[0002] The plate and frame filter press consists of a frame, a filter press chamber, filter plates, filter cloths, a filter press system and a waste liquid discharge system. The filter press system is a system in which a push plate is arranged between two filter plates. The push plate is pushed toward the wastewater by compressed air to complete the filter press step.

However, the compressed gas input into the filter press is compressed by the air compressor. In the actual production process, due to the limited use of compressed air, when multiple filter presses are used at the same time, there is a shortage of compressed gas, resulting in the filter press operation cannot obtain compressed gas, resulting in work interruption.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] The utility model provides Figure 1 and Figure 2A wastewater plate-frame water squeezing system shown in the figure comprises a filter press 1, a water tank 3 for storing water is arranged on one side of the filter press 1, an input component for inputting high-pressure water into the filter press 1 is arranged on one side of the water tank 3, the input component comprises a vertical squeezing pump 4 arranged on one side of the water tank 3 for extracting water from the water tank 3, an output end of the vertical squeezing pump 4 is fixedly connected to an squeezing water line pipe 5, a water inlet connecting pipe 2 is arranged at the water inlet of the filter press 1, one end of the squeezing water line pipe 5 away from the vertical squeezing pump 4 is fixedly connected to one end of the water tank 3, and an in-pipe pneumatic control valve 6 for controlling water pressure is arranged in the middle of the vertical squeezing pump 4.

[0019] It should be noted that the filter press 1 is used for filtering, washing and dehydrating solid particles. When in use, the feed valve is opened, and the suspension to be treated enters the filter press chamber through the feed pipe. The liquid will pass through the filter cloth, permeate the filter material under the action of pressure, and enter the filter plate cavity, thereby separating the solid and the liquid. Then, the pressure is increased, and the wastewater is squeezed by the push plate to squeeze out the water in the solid to increase the dehydration rate of the solid. Finally, the filtered filter cake is taken out from the filter press 1. When the water storage tank 3 is set, firstly according to the number of filter presses 1, , and then calculate the required water volume to design the size of the water tank 3; the vertical extrusion pump 4 is used to transport the water in the water tank 3 to the extrusion waterline pipe 5, and the in-pipe pneumatic control valve 6 adjusts the water pressure in the extrusion waterline pipe 5 by appropriately adjusting the opening of the pneumatic valve to maintain it within the set range. When in use, automatic control can be achieved by using the pneumatic valve in conjunction with a sensor, a control system, etc. Before use, the opening and closing time of the in-pipe pneumatic control valve 6 is first set through the control system, thereby reducing the workload of on-site personnel.

[0020] Furthermore, the filter plate of the plate and frame filter press 1 is changed from a compressed air extrusion plate to a water extrusion plate, and a new input component is provided to pass into the filter press 1. The extrusion pressure of the water input into the filter press 1 is controlled by the pneumatic control valve 6 in the pipe, and a new water storage tank 3 is added. The required water is added to the water storage tank 3 according to the number of equipment and the required amount of water.

[0021] Specifically, a connecting pipe 7 is inserted and connected to one side of the water tank 3 , and the connecting pipe 7 is fixedly connected to the input end of the vertical extrusion pump 4 .

[0022] Specifically, one end of the connecting pipe 7 away from the vertical extrusion pump 4 is fixedly connected to the water inlet pipe 9 , and the water inlet pipe 9 is inserted and connected to the inside of the water storage tank 3 .

[0023] It should be noted that the bottom end of the water inlet pipe 9 is located at the bottom of the water tank 3, and the two are not in contact with each other, so that when the water level in the water tank 3 drops, the water at the bottom of the water tank 3 is sucked through the water inlet pipe 9 whose water inlet is located at the bottom of the water tank 3.

[0024] Furthermore, when the water in the water tank 3 needs to be pumped out by the vertical squeeze pump 4 , the water inlet pipe 9 absorbs the water at the bottom of the water tank 3 and then inputs the water into the vertical squeeze pump 4 through the connecting pipe 7 .

[0025] Specifically, a water tank outlet ball valve 8 for controlling water flow is provided in the middle of the connecting pipe 7 , and a pump outlet ball valve 10 is provided on one side of the extrusion waterline pipe 5 close to the vertical extrusion pump 4 .

[0026] It should be noted that the water tank outlet ball valve 8 is used to close the connecting pipe 7 through the water tank outlet ball valve 8 when the vertical extrusion pump 4 needs to be disassembled; the pump outlet ball valve 10 is used to control the water flow in the extrusion waterline pipe 5. When the pneumatic control valve 6 in the pipe is damaged, the water flow in the extrusion waterline pipe 5 is controlled through the pump outlet ball valve 10.

[0027] Specifically, a first return pipe 11 for returning water to the water tank 3 is provided on one side of the squeezed waterline pipe 5. One end of the first return pipe 11 away from the squeezed waterline pipe 5 is inserted and connected to one side of the water tank 3. A return ball valve 12 for controlling the water flow is provided in the middle of the first return pipe 11.

[0028] Specifically, a second return pipe 14 is provided on one side of the squeezed waterline pipe 5 , an end of the second return pipe 14 away from the squeezed waterline pipe 5 is inserted and connected to one side of the water storage tank 3 , and a return pneumatic control valve 13 is provided in the middle of the second return pipe 14 .

[0029] It should be noted that the first return pipe 11 and the second return pipe 14 are both used to return water to the water storage tank 3. The return pneumatic control valve 13 arranged on the second return pipe 14 is consistent with the pneumatic control valve 6 in the pipe. When in use, the switch of the valve body is automatically controlled to reduce the operation of the staff. The first return pipe 11 and the return ball valve 12 are used for backup return water. When the return pneumatic control valve 13 is damaged and cannot be opened, the return ball valve 12 is opened to allow the return water to flow back to the water storage tank 3 through the first return pipe 11.

[0030] Specifically, the in-pipe pneumatic control valve 6 is disposed between the first return pipe 11 and the second return pipe 14 .

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
