Description

Drying equipment for fertilizers

Technical field

The present invention relates to the technical field of fertilizer drying, and in particular to a drying device for fertilizer.

Background technique

Fertilizer is a substance that is used to provide necessary nutrients for plants. It also has the function of improving soil properties and increasing soil fertility levels. During the production process of organic fertilizer, after fermentation, the fertilizer contains more water. In order to facilitate subsequent production, Fertilizer needs to be dried.

The existing fertilizer drying work generally uses a drum dryer. The drum dryer continuously rotates during the working process, causing the fertilizer inside the drum to be continuously turned over to achieve the drying effect. However, during the rolling process of the fertilizer, , Fertilizer particles are easily broken. After the fertilizer particles are broken, fertilizers with smaller particle diameters directly affect the quality of the product. In the process of fertilizer production, the broken fertilizer particles will cause fertilizer to be wasted. In addition, flip-stirring drying equipment is used , when this kind of equipment is drying, it constantly turns the fertilizer, which will also cause the fertilizer particles to break.

For example, the Chinese invention patent with announcement number CN110440557B discloses a drying device for biofertilizer, especially an easy-to-use drying device for biofertilizer, including a base, a cylinder, a drainage pipe, and a first valve. , water inlet pipe, second valve, cylinder, feed hopper, partition, swing plate, small connecting shaft, movable rod, etc.; the cylinder is located above the base, with a water tank, and an annular insert at the top of the cylinder. The annular slot is located above the water tank. The technical solution is to use a stirring plate to turn the fertilizer particles. During the turning process of the stirring plate, the fertilizer particles will inevitably be squeezed, causing the fertilizer particles to break. occur.

When the air extraction equipment is working, the gas containing a large amount of steam inside the drying cylinder 201 is extracted. During this process, the outside air enters the drying cylinder 201 through the vortex tube 402, realizing The gas flows inside the drying cylinder 201 to ensure the drying effect of the fertilizer. Turn on the switch of the electric heating pipe 304. The electric heating pipe 304 heats the water on the side of the partition 303 in the box 302 and generates steam. As the space As the steam in the cylinder increases, the air pressure rises, causing the boiling point of water to rise, thereby increasing the temperature of the steam. At this time, the steam enters the pneumatic cylinder 605 through the first connecting pipe 606, so that the pneumatic cylinder 605 is located below the first piston block 603 The air pressure rises, pushing the first piston block 603 to rise, driving the rack plate 601 to move through the pneumatic rod 602, and cooperating with the tooth groove 104 on the annular seat 102, so that the annular seat 102 can rotate to a certain angle, thereby making the inside of the drying barrel 201 The drying tank 702 is offset at a certain angle to realize the turning of fertilizer.

When the first solenoid valve 305 is opened, the air pressure in the pneumatic cylinder 605 below the first piston block 603 decreases. Under the action of the first spring 604, the air pressure passes through the first piston block 603, the pneumatic rod 602 and the rack plate. 601 drives the annular seat 102 to reversely rotate at a certain angle, thereby realizing the periodic rotation of the drying cylinder 201, ensuring the turning effect of the fertilizer, thereby ensuring the drying effect of the fertilizer. After drying for a period of time, the second solenoid valve is turned on 707 switch, the steam in the drying tank 702 and the connecting frame 703 enters the preheating box 401 through the output pipe 706, and contacts the vortex tube 402 inside the preheating box 401, heating the gas inside the vortex tube 402 , it is realized that after the device has been working for a period of time, the temperature of the drying gas entering the inside of the drying cylinder 201 is relatively high, which avoids the entry of outside gas and the lowering of the internal temperature of the drying cylinder 201, thereby ensuring the drying effect and at the same time making the preheating The steam inside the box 401 is liquefied. When the water inside the preheating box 401 reaches the movement level, it enters the box 302 through the one-way valve and the return pipe 403 to realize the recycling of water and avoid the waste of water resources. Compared with the transmission The steam heating equipment can effectively reduce the frequency of water injection during use of the drying device. When high-pressure steam enters the preheating box 401, it will also enter the U-shaped tube 501. When the air pressure in the U-shaped tube 501 rises, the steam The second piston block 504 rises, stretching the second spring 505. During the rising process, the second piston block 504 pushes the end of the drying tank 702 away from the chute 204 to rise through the transmission rod 502 and the transmission column 503, and cooperates with the slide block 704 The sliding between the chute 204 and the rotation between the connecting frame 703 and the drying tank 702 makes the drying tank 702 in an inclined state, causing the fertilizer inside the drying tank 702 to roll for a certain distance, thereby realizing the turning work of the fertilizer. Turn off the switch of the second solenoid valve 707 so that the preheating box 401 is no longer connected to the connecting frame 703. As the outside air enters through the vortex tube 402, the steam inside the preheating box 401 is liquefied. When the inside of the preheating box 401 After the steam is liquefied, the internal air pressure of the preheating box 401 decreases, and then under the action of the second piston block 504 and the second spring 505, the transmission rod 502 and the transmission column 503 are driven down, so that the drying tank 702 is in another tilted state. , thereby causing the fertilizer in the drying tank 702 to turn over again, ensuring full turning of the fertilizer and improving the drying efficiency. After closing the second solenoid valve 707, the air pressure inside the box 302 gradually increases again. When the air pressure increases, The greater the amount of steam, the greater the heat it carries, ensuring the heat supply during the drying process. In addition, compared with ordinary hot air drying technology, this drying device uses steam for heat transfer. Air pressure is used to turn the fertilizer, which not only ensures the drying effect of the fertilizer, but also improves the efficiency of the fertilizer.
