[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. The utility model can solve the problem that solid particles and impurities will accumulate in the filter plate during a long period of filtration by means of the filter plate flushing mechanism. These substances will gradually accumulate and block the filter holes, resulting in reduced filtration efficiency. The hose is connected to the external water source, and then the first motor is started to drive the screw to rotate, so that the slider slides and adjusts in the first slide groove, and then the connecting plate and the two first water pipes and the two second water pipes plugged thereon are driven to move and adjust through the slider, so that the two first water pipes and the two second water pipes are no longer located in the four compartments. When the connecting plate is moved to the appropriate position, the water source is turned on, and the water flows through the hose into the diversion pipe, and then is distributed to the first water pipe and the second water pipe. The water flows through the two-way nozzle and the single nozzle. Spray to the nozzle to clean both sides of the filter plate. At the same time, water is also sprayed out through the first bottom nozzle and the second bottom nozzle to ensure that the bottom of the filter plate and the bottom of the filter tank are fully cleaned. Through such reciprocating cleaning, it is ensured that the surface of the filter plate and the bottom of the filter tank are cleaned without dead corners, thereby improving the cleaning efficiency and quality. After cleaning, turn off the water source, wait for the connecting plate to reset to the initial position, and turn off the first motor to complete the cleaning process. This not only improves the cleaning efficiency and quality, but also realizes automated operation, saves manpower and water resources, and effectively solves the problem that the filter plate will accumulate solid particles and impurities during the long-term filtration process. These substances will gradually accumulate and block the filter holes, resulting in reduced filtration efficiency.

The utility model can solve the problem that manual workers regularly stop the equipment and disassemble the filter plates for cleaning, which increases the frequency and labor intensity of maintenance work, and also increases the production downtime. By setting the second motor, gears and toothed plates, the six second motors are divided into three groups, and the two second motors in each group are arranged oppositely. By controlling the operation of the three groups of second motors on the three fixed plates respectively, the six gears rotate and mesh with the adjacent toothed plates for transmission. At the same time, the six toothed plates slide in the three second chutes respectively, driving the three filter plates to lift upward. At this time, the three filter plates can be taken out of the filter tank for replacement. According to the loss rate of the filter plates, the filter plates that need to be replaced can be replaced separately. Such a design is convenient for the replacement of the filter plates, and a certain filter plate can be replaced separately according to the loss requirement. Compared with the traditional method, replacing the filter plates often requires completely stopping the equipment, while this design allows partial or all filter plates to be replaced during the operation of the equipment, greatly reducing the production downtime caused by maintenance, and effectively solving the problem that manual workers regularly stop the equipment and disassemble the filter plates for cleaning, which increases the frequency and labor intensity of maintenance work, and also increases the production downtime.

Specific embodiments

[0026] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] Such as Figure 1 - Figure 9As shown in the figure, a flat washing and filtering device includes a bottom plate 1, on which a filtering tank 2 is fixedly connected. Four partition chambers 4 are connected to both sides of the filtering tank 2 at equal intervals and communicate with each other. A filter plate washing mechanism 3 is arranged on the filtering tank 2. The filter plate washing mechanism 3 includes two fixing blocks 301, and the two fixing blocks 301 are fixedly connected to the filtering tank 2 at equal intervals. First sliding grooves 302 are opened on both of the two fixing blocks 301. Screw rods 303 are rotatably connected in the two first sliding grooves 302. One ends of the two fixing blocks 301 are fixedly connected with first motors 306 respectively. Output shafts of the two first motors 306 respectively pass through the two fixing blocks 301 and are fixedly connected with the two screw rods 303. Sliders 304 are slidably arranged in the two first sliding grooves 302. The two sliders 304 are respectively threadedly connected to the two screw rods 303. A connecting plate 305 is fixedly connected to the two sliders 304. Two first water pipes 307 are fixedly inserted into the connecting plate 305 at equal intervals. A number of bidirectional nozzles 308 are connected to the two first water pipes 307 at equal intervals and communicate with each other. A first bottom nozzle 309 is connected to the lower ends of the two first water pipes 307 and communicates with them. Two second water pipes 310 are fixedly inserted into the connecting plate 305 at equal intervals. The two second water pipes 310 are respectively located on one side of the two first water pipes 307. A number of unidirectional nozzles 311 are connected to the two second water pipes 310 at equal intervals and communicate with each other. Second bottom nozzles 312 are connected to the lower ends of the two second water pipes 310 and communicate with them. A flow dividing pipe 313 is arranged on the connecting plate 305. The two first water pipes 307 and the two second water pipes 310 are both connected to the flow dividing pipe 313 and communicate with it. A flexible pipe 314 is connected to the flow dividing pipe 313 and communicates with it. The two first water pipes 307 and the two second water pipes 310 are respectively located in the four partition chambers 4. By adopting the above technical solution: Connect the flexible pipe 314 to the water source, then start the first motor 306 to drive the screw rod 303 to rotate, so that the slider 304 slides and adjusts in the first sliding groove 302. Then, the connecting plate 305 and the two first water pipes 307 and the two second water pipes 310 inserted thereon are driven by the slider 304 to move and adjust, so that the two first water pipes 307 and the two second water pipes 310 are no longer located in the four partition chambers 4. When the connecting plate 305 moves to an appropriate position, turn on the water source. The water flows through the flexible pipe 314 into the flow dividing pipe 313, and then is distributed to the first water pipes 307 and the second water pipes 310. The water is sprayed through the bidirectional nozzles 308 and the unidirectional nozzles 311 to clean both sides of the filter plate 5. At the same time, the water also sprays out through the first bottom nozzle 309 and the second bottom nozzle 312 to ensure that the bottom of the filter plate and the bottom of the filtering tank 2 are fully cleaned. Through such reciprocating cleaning, it is ensured that there are no dead corners in cleaning the surface of the filter plate and the bottom of the filtering tank 2, improving the cleaning efficiency and quality. After the cleaning is completed, turn off the water source. Wait for the connecting plate 305 to return to the initial position, and at the same time turn off the first motor 306 to complete the cleaning process. This design improves the cleaning efficiency and quality, and also realizes automatic operation, saving manpower and water resources.

[0028] AsFigure 1 - Figure 6 As shown in Figure 6 , three second chutes 7 are equidistantly arranged on the filter tank 2. Filter plates 5 are equidistantly arranged in the filter tank 2. Tooth plates 6 are fixedly connected to both ends of the three filter plates 5. The six tooth plates 6 are divided into three groups, and the three groups of tooth plates 6 slide in the three second chutes 7 respectively. Three fixing plates 8 are equidistantly and fixedly connected to both sides of the filter tank 2. The six fixing plates 8 are divided into three groups, and groove-shaped limit blocks 11 are fixedly installed on each group of the three fixing plates 8. Second motors 9 are fixedly installed on each group of the three fixing plates 8. Output shafts of the six second motors 9 are respectively movably inserted through the adjacent groove-shaped limit blocks 11 and fixedly connected with gears 10. The six gears 10 are respectively meshed with the adjacent tooth plates 6. By adopting the above technical solution: The six second motors 9 are divided into three groups, and the two second motors 9 in each group are arranged oppositely. By respectively controlling the three groups of second motors 9 on the three fixing plates 8 to work, the six gears 10 rotate and mesh with the adjacent tooth plates 6 to drive, and at the same time, the six tooth plates 6 slide in the three second chutes 7 respectively, driving the three filter plates 5 to be lifted upward. At this time, the three filter plates 5 can be taken out of the filter tank 2 for replacement. Also, according to the loss rate of the filter plates 5, the filter plates 5 that need to be replaced can be replaced individually. Such a design facilitates the replacement of the filter plates 5 and can also replace a certain filter plate 5 according to the loss requirement. The groove-shaped limit blocks 11 provided accurately guiding paths for the tooth plates 6. Since the tooth plates 6 are connected to the filter plates 5, the groove-shaped limit blocks 11 indirectly provide guidance for the movement of the filter plates 5, ensuring that the filter plates 5 can move smoothly along the preset trajectory without deviation or jamming.

[0029] As Figure 1 - Figure 4 As shown in Figure 4 , one end of the filter tank 2 is connected to a connecting pipe 16 in a communicating manner. One end of the connecting pipe 16 far from the filter tank 2 is connected to a clear water tank 17 in a communicating manner. The clear water tank 17 is fixedly connected to the bottom plate 1. One end of the clear water tank 17 is connected to a water outlet pipe 18 in a communicating manner. A second valve 19 is installed on the water outlet pipe 18. By adopting the above technical solution: The water filtered by the filter tank 2 flows through the connecting pipe 16 and into the clear water tank 17. When the water in the clear water tank 17 needs to be discharged, the second valve 19 is opened, and the water flows out through the water outlet pipe 18.

[0030] As Figure 2 - Figure 4 As shown in Figure 4 , L-shaped connecting pipes 12 are connected to the lower ends of the eight partition chambers 4 in a communicating manner. A sewage pipe 13 is arranged below the bottom plate 1. The eight L-shaped connecting pipes 12 are all connected to the sewage pipe 13 in a communicating manner. A first valve 14 is installed on the sewage pipe 13. By adopting the above technical solution: The eight L-shaped connecting pipes 12 provided facilitate the discharge of the sewage after flushing and flow into the sewage pipe 13. At this time, the first valve 14 is opened to discharge the sewage.

[0031] As Figure 1 -Figure 4 As shown, one end of the filtration tank 2 is connected to a water inlet pipe 15 in a communicating manner. Four legs 20 are fixedly connected to the lower end of the bottom plate 1 at equal intervals. By adopting the above technical solution: the four legs 20 provided can play a role in supporting and fixing the bottom plate 1, and the water inlet pipe 15 provided facilitates the injection of sewage to be filtered.

[0032] A control panel 21 is fixedly installed at one end of the filtration tank 2. The output ends of the control panel 21 are electrically connected to the first motor 306 and the second motor 9 respectively.

[0033] It should be noted that the present utility model is a flat washing and filtering device. When in use, first place the device at a designated position, and connect the first motor 306, the second motor 9 and the control panel 21 to an external power source to supply power to the device.

[0034] The sewage is injected through the water inlet pipe 15 and flows into the filtration tank 2. Through the hierarchical filtration of the three filter plates 5 in the three filtration tanks 2, the filtered water flows through the connecting pipe 16 and into the clear water tank 17. When it is necessary to discharge the water in the clear water tank 17, open the second valve 19, and the water flows out through the water outlet pipe 18. The four legs 20 provided can play a role in supporting and fixing the bottom plate 1.

[0035] When the filter plate is blocked after long-term filtration, affecting the filtration efficiency, connect the hose 314 of the filter plate washing mechanism 3 to an external water source, and then start the first motor 306 to drive the screw 303 to rotate, so that the slider 304 slides and adjusts in the first chute 302 on the fixed block 301. Then, the connecting plate 305 and the two first water pipes 307 and two second water pipes 310 inserted thereon are driven by the slider 304 to move and adjust, so that the two first water pipes 307 and the two second water pipes 310 are no longer located in the four partition chambers 4. When the connecting plate 305 moves to an appropriate position, turn on the water source. The water flows through the hose 314 into the shunt pipe 313, and then is distributed to the first water pipe 307 and the second water pipe 310. The water is sprayed through the bidirectional nozzles 308 and the unidirectional nozzles 311 to clean both sides of the filter plate 5. At the same time, the water also sprays out through the first bottom nozzle 309 and the second bottom nozzle 312 to ensure that the bottom of the filter plate and the bottom of the filtration tank 2 are fully cleaned. During the reciprocating cleaning process, the sewage flows into the eight L-shaped connecting pipes 12 respectively, and the sewage flows into the sewage pipe 13. At this time, open the first valve 14 to discharge the sewage, ensuring that there are no dead corners in the cleaning of the filter plate surface and the bottom of the filtration tank 2, improving the cleaning efficiency and quality. After the cleaning is completed, turn off the water source, wait for the connecting plate 305 to reset to the initial position, and at the same time turn off the first motor 306 and the first valve 14 to complete the cleaning process. This not only improves the cleaning efficiency and quality, but also realizes automatic operation, saving manpower and water resources.

[0036] When it is necessary to replace the loss filter plate 5, by controlling the operation of the three groups of second motors 9 on the three groups of fixed plates 8 respectively, the six gears 10 are rotated to engage and drive the adjacent toothed plates 6, and at the same time, the six toothed plates 6 slide in the three second chutes 7 respectively, driving the three filter plates 5 to lift upward. The provided groove-shaped limit blocks 11 provide an accurate guiding path for the toothed plates 6. Since the toothed plates 6 are connected to the filter plates 5, the groove-shaped limit blocks 11 indirectly provide guidance for the movement of the filter plates 5, ensuring that the filter plates 5 can move smoothly along the preset trajectory without skewing or jamming. At this time, the three filter plates 5 can be withdrawn from the filtration tank 2 for replacement. Also, according to the loss rate of the filter plates 5, the filter plates 5 that need to be replaced can be replaced individually. Such a design facilitates the replacement of the filter plates 5 and allows for the individual replacement of a certain filter plate 5 according to the loss requirements. Compared with the traditional method, replacing the filter plate 5 often requires completely stopping the equipment, while this design allows for the replacement of some or all of the filter plates during the operation of the equipment, greatly reducing the production downtime caused by maintenance.
