Detailed ways

The present invention will be described in detail below with reference to the accompanying drawings and examples.

The warm water storage tank is to solve the problem that the on-site eyewash can use the warm water source. It can provide the warm water source for the eyewash to prevent the injured from using the cold water source to cause secondary injury. The device adopts a single-channel reverse layering. The lamination technology effectively slows down the mixing speed of hot and cold water, and can provide an effective source of warm and hot water for the eyewash.

Since the electric heating cable is used to heat the water source in the water storage tank, even if the thermostat of the electric heating cable fails, the temperature of the water source in the water storage tank will not increase rapidly, avoiding the failure of the thermostat when using steam or electric heaters The technical problem of rapidly increasing the water temperature in the water storage tank.

The warm water storage tank can provide a water source temperature of 20 to 37°C for the spray of a single eye washer (water flow: 85L/MIN), and 35 to 35 to the eyewash for a single eyewash (water flow: 15L/MIN). The temperature of the water source is 37°C, and the capacity of the water storage tank can be increased to provide warm water source for 2 or more eyewashes.

In the actual use process, a regulating valve is set at the rear end of the spray ball valve and the eye wash valve to control the spray water flow and the eye wash water flow. Regardless of the size of the water supply pipe and the pressure of the water supply source, it is only necessary to control the water flow. .

As shown in Figure 1, the warm water storage tank includes a frame 1, a drain valve 2, a water storage tank 3, an electric heating cable 4, a thermal insulation layer 5, a casing 6, a thermostat 7, a power junction box 8, and a top cover 9 , hoisting ring 10, exhaust port 11, temperature display instrument 12, exhaust valve 13, laminate 14;

The water storage tank 3 is installed inside the frame 1, and the self-controlled electric heating cable 4 is used to heat the water source inside the water storage tank 3, and a thermostat 7 is set to control the temperature of the heated water source, so as to prevent the high-temperature water source from being supplied to the eyewash. The temperature display instrument 12 is used for on-site observation of the temperature of the water source in the water storage tank, and the power junction box 8 is provided for on-site power supply;

An insulating layer 5 and an outer shell 6 are arranged outside the water storage tank 3 to prevent the heat dissipation of the electric heating cable 4, and a top cover 9 is arranged on the top to prevent the rainwater from leaking into the insulating layer 5 outside the water storage tank 3 on a rainy day, and To affect the heating efficiency, four hoisting rings 10 are arranged on the top cover 9 for hoisting the equipment during installation.

Set the exhaust port 11 and the exhaust valve 13 to discharge the gas inside the water storage tank when the water is in hygienic requirements.

Single-lane, layered technology

The water inlet a of the warm water storage tank is connected to the on-site water supply pipeline, and the water outlet b is connected to the eyewash or eyewash water supply pipeline. The inside of the water storage tank is provided with a layered layer 14, which is assumed to be divided into n layers. Between a and the water outlet b, single-channel pipes C1, C2, C3... The water source inside is not directly from the water inlet a to the water outlet b. The more layers there are, the slower the mixing speed between the cold water source provided on site and the hot water source in the water storage tank.

reverse technology

In the first layer, the angle between the water inlet C0 of the water inlet a and the water outlet C1 of the water storage tank is not consistent, and the optimal angle is 180° (the same below), and the water inlet C0 of the water storage tank is at the first layer. The highest point position that can be installed, the water outlet C1 is at the lowest point of the first layer, and the first layer water outlet C1 is also the second layer water inlet;

In the second layer, the angle between the water outlet C1 of the first layer and the water outlet C2 of the second layer is 180°. lowest point position. The second layer water outlet C2 is also the third layer water inlet;

In the third layer, the angle between the water outlet C2 of the second layer and the water outlet C3 of the third layer is 180°, the water outlet C2 of the second layer is at the highest point of the third layer, and the water outlet C3 is in the third layer lowest point position. The water outlet C3 of the third layer is also the water inlet of the Cn-1 layer

and so on

In the nth layer, the angle between the water outlet Cn of the n-1th layer and the water outlet Cn+1 of the nth layer is 180°, and the water outlet Cn-1 of the n-1th layer is at the highest point of the nth layer. The water outlet Cn is at the lowest point of the nth layer. The water outlet C3 of the n-1st layer is the water inlet of the Cn-1th layer, and the water outlet Cn+1 of the nth layer is the water outlet b of the water storage tank.

The above layering technology and reverse technology can effectively ease the mixing speed of the cold water source on site and the hot water source inside the water storage tank

Lamination technology

Since the interior of the water storage tank (3) is layered by the layers (14), and the pipes (C) are used for reverse connection between the layers, the cold water source is provided on site through the water pressure from the first layer to the last nth layer, Provide a source of warm water to the eyewash.

Use process

1. After installing the warm water storage tank, connect the water inlet a to the on-site pipeline, and the water outlet b to the eyewash or the water supply pipe provided to the eyewash;

2. Open the water inlet a, let the on-site water source enter the water storage tank 3, and open the exhaust valve 13 to discharge the gas in the water storage tank 3. Since the water storage tank 3 adopts the layering technology, the above operations need to be repeated many times. Only then can the gas in the water storage tank 3 be discharged cleanly until the exhaust valve 13 is full of water;

3. Connect the on-site power supply to supply power to the electric heating cable 4, and the temperature of the water source inside the water storage tank 3 is controlled by the thermostat 7. Normally, the temperature of the thermostat 7 is set to 37°C (due to the mechanical thermostat, the temperature control The value has a certain deviation, the deviation value is about 2 ℃), once the temperature of the water source inside the water storage tank 3 reaches 37 ℃, the thermostat 7 will automatically cut off the power supply of the electric heating cable 4, so that the electric heating cable 4 will no longer be heated. When the temperature of the water source inside the water tank 3 is lower than 35°C, the thermostat 7 is automatically connected to the power supply of the electric heating cable 4, so that the electric heating cable 4 is heated again;

4. Since the electric heating cable 4 is used to heat the water source in the water storage tank 3, even if the thermostat 7 of the electric heating cable 4 fails, the temperature of the water source in the water storage tank 3 will not increase very quickly. Avoid using steam or electric heating. There is a technical problem that the failure of the thermostat 7 will rapidly increase the water temperature in the water storage tank.

The parts of the present invention that are not described in detail belong to the common knowledge of those skilled in the art.
