DETAILED DESCRIPTION

[0042] In view of the deficiencies in the prior art, the inventor of this case has proposed the technical solution of the present invention after long-term research and extensive practice. The technical solution, its implementation process and principle will be further explained as follows.

[0043] like Figure 1 , Figure 2As shown, the present invention discloses a filter bag cleaning device, including a water treatment system, a cleaning mechanism 8, a centrifugal mechanism 9 and a container 1, wherein the cleaning mechanism 8, the centrifugal mechanism 9 and the water treatment system are all arranged in the container 1. When the manufacturer needs to clean the filter bag, the container 1 is hoisted on a transport vehicle, and the filter bag cleaning device can be transported by one vehicle, which greatly saves the transportation cost. The cleaning mechanism 8 is at least used to clean the filter bag. When cleaning, the filter bag is placed in a net bag and put into a cleaning machine for cleaning; the centrifugal mechanism 9 is at least used to spin dry the cleaned filter bag; in order to filter the sewage after cleaning the filter bag, the water treatment system is connected to the cleaning mechanism 8, and the water treatment system can process the sewage after cleaning the filter bag, so that the water circulates between the cleaning mechanism 8 and the water treatment system, which greatly saves water resources.

[0044] Specifically, Figure 3 As shown, the water treatment system includes a pipeline system, and the pipeline system is connected with a water storage tank 2, a sewage tank 3, a filter press assembly 4 and a clean water tank 5. The sewage passes through the water storage tank 2, the sewage tank 3, the filter press assembly 4 and the clean water tank 5 in sequence, and the sewage passes through the filter press assembly 4 to become clean water; the water storage tank 2 is used to collect the sewage to be filtered, and the sewage tank 3 is used to store the sewage to be filtered. In order to stir the sewage evenly and prevent the sludge from sinking, a stirring assembly 11 is arranged in the sewage tank 3, and the sewage can be mixed evenly under the drive of the stirring assembly 11. The two ends of the pipeline system are respectively connected to the water inlet and outlet of the cleaning machine. The sewage discharged by the cleaning machine passes through the water storage tank 2, the sewage tank 3, the filter press assembly 4 and the clean water tank 5 in sequence, and the water circulates among the cleaning machine, the water storage tank 2, the sewage tank 3, the filter press assembly 4 and the clean water tank 5.

[0045] In some implementation cases, in order to treat the water discharged from the centrifugal mechanism 9 , the discharge end of the centrifugal mechanism 9 is connected to a water treatment system so that the water treatment system can treat the water discharged from the centrifugal mechanism 9 .

[0046] In some implementation cases, the filter press assembly 4 is used to filter sewage and press the sludge into a mud cake, and the clean water tank 5 is used to store the filtered clean water for recycling. The present application can filter the sewage after cleaning the filter bag, so that the water can be recycled, reducing the amount of water used and greatly reducing the cost.

[0047] like Figure 4As shown, the filter press assembly 4 includes a crossbeam 401, on which a plurality of filter press plates 402 and filter press frames 403 are arranged at intervals along the crossbeam 401; each of the filter press plates 402 is wrapped with a filter press cloth, which is made of needle felt or high-precision woven cloth. The high-precision woven cloth is finely woven, and the filter material produced has high-precision filtering performance during use, and ensures good permeability and is not easy to clog. The filter press in the existing water treatment system cannot meet the water treatment requirements, and flocculants need to be used to make small particles clump together to reduce the difficulty of filtering; however, the water after using the flocculant will become sticky, and the filter bag cannot be cleaned. The present application uses needle felt or high-precision woven cloth to make filter press cloth, which can filter out fine particles in sewage. Compared with the traditional method of using flocculants to filter out fine particles and make the fine particles clump together, the present application uses physical methods to filter out fine particles, avoids chemical reactions, reduces costs, and avoids the treated water from becoming viscous. The water treated by the present application is cleaner and can meet the requirements of recycling.

[0048] A clamping assembly 405 is provided on the outer side of the filter press plate 402 or the filter press frame 403 at the outermost end of the crossbeam 401. Driven by the clamping assembly 405, a closed filter chamber is formed between the filter press plate 402, the filter press frame 403 and the filter cloth. The corresponding positions of the filter press plate 402 and the filter press frame 403 are respectively provided with a first through hole and a second through hole. When the filter chamber is in a closed state, a plurality of the first through holes form a water inlet channel, and a plurality of the second through holes form a drainage channel. Sewage enters the filter chamber through the water inlet channel, and the sewage passes through the filter press cloth to filter impurities on the outer side of the filter press plate 402. The filtered clean water enters the drainage channel along the groove of the filter press plate 402 and is discharged.

[0049] On the basis of the above, in order to extend the service life of the filter press cloth, acid and alkali resistant needle felt or high-precision woven cloth is selected.

[0050] Preferably, the temperature resistance range of the filter press cloth is -30 to 250 degrees Celsius.

[0051] Specifically, Figure 5As shown, the clamping assembly 405 includes a first pressure plate 408 and a second pressure plate 409 arranged at both ends of the filter chamber, the first pressure plate 408 or the second pressure plate 409 is fixed on the crossbeam 401, and one side of the second pressure plate 409 or the first pressure plate 408 is provided with a first driving assembly 410 for driving the second pressure plate 409 or the first pressure plate 408 to approach the first pressure plate 408 or the second pressure plate 409. Under the drive of the first drive component 410, one of the press plates moves toward or away from another press plate. Before the sewage needs to be filtered, the first drive component 410 drives one press plate to move toward another press plate (the moving press plate moves toward the fixed press plate) to press the filter plate 402, the filter press frame 403 and the filter press cloth, so that a closed filter chamber is formed between the filter plate 402, the filter press frame 403 and the filter press cloth; when the pressure in the filter chamber is too high, that is, when the filter cake needs to be unloaded, the first drive component 410 drives one press plate to move away from another press plate, so that the adjacent filter plates 402 and the filter press frame 403 are separated, so that the filter cake can fall out easily. The first drive component 410 may include an oil cylinder and may also include a motor and a screw rod. In this embodiment, the first drive component 410 includes an oil cylinder, and the driving end of the oil cylinder is fixedly connected to the movable press plate.

[0052] In some implementation cases, in order to save manpower and improve the efficiency of cake unloading, an automatic cake unloading assembly 6 is arranged on one side of the filter press plate 402, and the automatic cake unloading assembly 6 is at least used to unload the mud cake attached to the surface of the filter press cloth. Specifically, the automatic cake unloading assembly 6 includes two paddles arranged on both sides of the filter press plate 402, and one side of the paddle is provided with a second drive assembly for driving the two paddles to be relatively close and a third drive assembly for driving the paddle to move to drive the filter press plate 402 to move along the crossbeam 401. The second drive assembly is used to drive the two paddles to be relatively close, so that the distance between the two paddles is less than the width of the filter press plate 402 or the filter press frame 403. Under the drive of the third drive assembly, the two paddles can drive the filter press plate 402 and the filter press frame 403 to move, so that the two adjacent filter press plates 402 and the filter press frame 403 are separated, so that the filter cake falls. The second drive assembly and the third drive assembly include a cylinder and may also include a motor and a screw rod. In this implementation case, the second drive assembly and the second drive assembly both include a cylinder.

[0053] On the basis of the above, in order to transfer the fallen mud cake, a transmission component 7 is arranged below the filter press plate 402. The mud cake is transferred out under the driving of the transmission component 7, which saves manpower and improves work efficiency. Figure 6 As shown, the transmission component 7 includes a transmission belt 701 and a power component 702 for driving the transmission belt 701 to transmit. The power component 702 includes a sprocket and a chain. The chain is connected to the transmission belt 701 to drive the transmission belt 701 to transmit.

[0054] Another aspect of the present invention also discloses a filter bag cleaning method, based on a filter bag cleaning device, comprising the following steps:

[0055] S1. Put the filter bag to be cleaned into the cleaning mechanism for cleaning;

[0056] S2, water treatment system to treat sewage;

[0057] S3. The cleaned filter bag is placed in a centrifugal mechanism for centrifugal treatment.

[0058] On the basis of the above, the steps of treating sewage in the water treatment system include:

[0059] S10, installing the filter press plate and the filter press frame, the pressing assembly presses the filter press plate and the filter press frame, and the filter press plate, the filter press frame and the filter press cloth form a closed filter chamber; specifically, the step of installing the filter press plate and the filter press frame in S10 includes: S100, wrapping the needle felt or high-precision woven cloth on the filter press plate, and fixing the needle felt or high-precision woven cloth on the filter press plate; S200, connecting the filter press plate and the filter press frame to the crossbeam, and the filter press plate and the filter press frame are arranged at intervals;

[0060] S20, the sewage in the water storage tank is pumped into the sewage tank by a first water pump;

[0061] S30, the second water pump pumps the sewage in the sewage tank into the water inlet channel;

[0062] S40, sewage enters the filter chamber through the water inlet channel, passes through the filter press cloth and enters the drainage channel along the filter press plate groove;

[0063] S50: The filtered water flows into the clean water tank from the drainage channel.
