Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In describing the present invention, when it is determined that a detailed description of a related known function or configuration may unnecessarily flow the gist of the present invention, the detailed description thereof will be omitted.

In the non-metal sludge collecting device of the present invention, all components including a pintle chain and a sprocket and a chain for driving the pintle chain to collect sludge are made of non-metallic material to improve corrosion resistance, and to prevent chains from being overloaded. It should be noted that it is a non-metallic sludge collection device that detects this and stops the sludge collection device, and notifies the worker.

1 to 3, the sludge collecting device according to the preferred embodiment of the present invention includes a drive motor 10, a drive sprocket 20, drive collector sprockets 30 and 30 ', and a support collector sprocket ( 40, 40 '), pintle chains (50, 50'), flight (60), drive detection means (70), control unit (80), and installed in the sedimentation tank (100) of the wastewater treatment plant. And the sludge settled on the bottom of the settling tank 100 is collected to the hopper 110 side.

The drive motor 10 is installed on the upper slab 120 of the settling tank 100, is supplied with power from the outside to provide a driving force for the rotation of the pintle chain (50, 50`).

The drive sprocket 20 is installed on one side wall 101 of the settling tank 100 so as to be located inside the settling tank 100, and is connected to and rotated by the driving motor 10 and the driving chain 11. At this time, the driving sprocket 20 is made of cast nylon (CAST NYLON-6).

Two driving collector sprockets 30 and 30` are provided to be installed on both side walls 101 and 102 of the settling tank 100, respectively, and two driving collector sprockets 30 and 30` provided are made of fiber-reinforced plastics. In addition to being connected to each other by the drive shaft 21 and coaxial with the drive sprocket 20 is rotated in conjunction with the drive sprocket 20, the same as the drive sprocket 20 is made of cast nylon.

The support collector sprockets 40 and 40` are provided in plural, and the pintle chain has a predetermined arrangement structure with the driving collector sprockets 30 and 30` installed on both side walls 101 and 102 of the settling tank 100, respectively. It is installed on both side walls (101, 102) of the settling tank 100 so that 50, 50` can be rotated like an orbit. 1 and 2 show three support collector sprockets installed on each wall 101, 102. These support collector sprockets 40 and 40 'are made of cast nylon.

On the other hand, the cast nylon constituting the various sprockets (20, 30, 30`, 40, 40`) has a high tensile strength, rigidity and shock absorption, lightweight and high corrosion resistance to reduce the weight of the sludge collection device It will help to prevent corrosion caused by various sludge and environmental factors.

The pintle chain (50, 50`) is rotated while the pair of pintle chain (50, 50`) in parallel to each other to move the flight 60, to collect the sludge is settled, The collector collector sprockets 30 and 30 'and the collector collector sprockets 40 and 40` installed on both walls 101 and 102 of the settling tank 100 are mounted to form a closed curve. This pintle chain (50, 50 ') is made of polybutylene terephthalate (PBT). As such, the polybutylene terephthalate constituting the pintle chain 50 has high strength and stiffness, and has a very low water content of 0.07% or less, so that the sludge collection device can maintain the same tensile strength even after long-term use in water. Helps improve durability.

The flight 60 is provided in plural, the plurality of flights 60 is fixed to both ends of the pair of pintle chain (50, 50`), maintain equal intervals along the pintle chain (50, 50`) To be installed. This flight 60 is made of fiber reinforced plastic (FRP). In addition, a scraper lip is formed at the lower end of the flight 60 to improve the collection of sludge. As shown in FIGS. 4 and 5, the scraper lip 61 protrudes toward the lower end of the flight 20 and is integrally formed at the lower end of the flight 20 so as to form a plurality of regular intervals. The lower end of this scraper lip 61 is formed in a semicircle whose side cross-sectional shape protrudes convexly toward the bottom of the sedimentation basin. Accordingly, when collecting the sludge accumulated in the sedimentation basin, it is possible to collect the sludge to the hopper 100 without catching the bottom of the sedimentation basin. On the other hand, the fiber-reinforced plastic constituting the flight 60 has an advantage that the strength per unit weight is relatively large.

As shown in Figures 1 and 6,7, the drive detecting means 70 detects the normal operation of the sludge collecting device by detecting the rotation of the support collector sprockets (40, 40`), proximity sensor And a sensing plate 72. Two proximity sensors 71 are provided to sense the rotation of the support collector sprockets 40 and 40` installed on both side walls 101 and 102 of the settling tank 100. That is, as shown in FIG. 1, one proximity sensor is installed to be adjacent to one selected sprocket among the plurality of support collector sprockets 40 supporting the chain 50 positioned on the left side, and positioned on the right side. The other one of the proximity sensors is installed so as to be adjacent to the selected one of the plurality of support collector sprocket (40`) for supporting the chain 50` support collector sprocket 40, 40`) rotation is detected. In this case, the proximity sensor 71 is fixed to the wall of the sedimentation basin and is fixed by the bracket 73 extending toward the support collector sprockets 40 and 40`. The sensing plate 72 is installed to rotate in conjunction with the support collector sprockets 40 and 40` on the side of the selected support collector sprockets 40 and 40`, and the proximity sensor 71 is disposed on one surface thereof. A plurality of detection pieces 74 are provided to generate a signal periodically. The detection pieces 74 are circularly arranged on the basis of the center of rotation of the sensing plate 72, and are arranged to have an equiangular interval therebetween so that the proximity sensor 71 periodically signals the rotation of the support pieces sprocket 40. It is installed to generate.

The control unit 80 receives a signal generated from the proximity sensor 71 to check whether the sludge collection device is in normal operation, and is provided with a notification means for notifying the worker when an abnormal condition is detected. That is, when the signal generated from the proximity sensor 71 is input at a constant cycle, the controller 80 recognizes that the sludge collecting device is normally driven. On the contrary, the controller 80 cannot receive a signal from the proximity sensor 71 at a constant cycle. In this case, as an example, if the pintle chain 50 is broken and the support collector sprocket 40 is stopped, the sludge collecting device is not normally operated to stop the driving motor 10 and notify the worker through the notification means. do.

The notification means may be made of a lamp for emitting light or a speaker for emitting sound.

The sludge collection device of the present invention configured as described above is a pair connected by the drive sprocket 20 and the drive shaft 21 when the driving force of the drive motor 10 rotates the drive sprocket 20 through the drive chain 11. Drive collector sprockets 30 and 30 'are rotated, and pintle chains 50 and 50' coupled to the drive collector sprockets 30 and 30 'are rotated.

By the rotation of the pintle chain (50, 50`) as described above, the support collector sprockets (40, 40`) also rotates to support the rotation of the pintle chain (50, 50`). At this time, the flight 60 installed in the pintle chain (50, 50`) is to push the sludge at the bottom of the sedimentation basin toward the hopper 110 of the sedimentation basin. The proximity sensor 71 detecting the rotation of the support collector sprocket 40 periodically generates a signal by the rotating sensing plate 72 and transmits the signal to the control unit 80, and the control unit 80 transmits the signal. On the basis of this, it is confirmed that the sludge collecting device is operating normally.

On the other hand, when a large load is applied to the pintle chain (50, 50`) due to a large amount of sludge or other causes beyond the design value and the pintle chain 50 is broken, the support collector rotated by the pintle chain 50 The sprockets 40 are stopped, and the rotation of the sensing plate 72 is also stopped. As the sensing plate 72 stops as described above, the proximity sensor 71 becomes unable to generate a periodic signal, and the controller 80 that senses this cuts off the power of the driving motor 10, and controls the operator as light or sound. Notify the abnormal condition to enable a quick repair.

The present invention is not limited to the above-described specific preferred embodiments, and various modifications can be made by any person having ordinary skill in the art without departing from the gist of the present invention claimed in the claims. Of course, such changes will fall within the scope of the claims.

According to the present invention, all the components including the pintle chain and various sprockets and flights constituting the sludge collecting device are made of non-metal to improve corrosion resistance against various contaminants such as sludge, and are lighter than metal materials. And easy to maintain. In addition, by detecting the rotation state of the support sprocket continuously checking whether the sludge collecting device is abnormal, it is possible to respond quickly in the event of an error.
