[0022] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0023] like Figures 1 to 4 As shown, a filter press that is easy to clean includes an electric telescopic beam 1 and a pressure plate cleaning assembly 2. The lower end of the right side of the electric telescopic beam 1 is equipped with an electric lifting rod 3. The pressure plate cleaning assembly 2 for convenient cleaning of the pressure plate is arranged at the lower end of the electric lifting rod 3, and the pressure plate cleaning assembly 2 includes a fixed frame 201, an electric rotating shaft 202, a flushing water pipe 203, a water spray hole 204 and a brush cover 205. The lower end of the side of the fixed frame 201 is equipped with an electric rotating shaft 202, and the outside of the electric rotating shaft 202 is provided with a flushing Water pipe 203, a water spray hole 204 is opened on the surface of the flushing water pipe 203, and a brush cover 205 is provided on the outside of the flushing water pipe 203, a transverse slide rail 12 is installed at the lower end of the control box 5, and a transverse slider 13 is installed on the outside of the transverse slide rail 12, a slider transport block 15 is provided at the bottom of the side of the filter press plate 14, a rubber belt line 17 is provided below the transverse slide rail 12, and a rotating roller 16 is installed inside the rubber belt line 17, and a decontamination slope 21 is provided on the right side of the rubber belt line 17;

[0024] The specific operation is as follows: After the filtration is completed, the electric push rod 8 retracts, and the filter press plate 14 is driven to retract to the far left. The lower end of the side of the filter press plate 14 is installed with a slider transport block 15, and a horizontal slide rail 12 is provided below. The horizontal slider 13 straightens the first pressure plate on the far right and fits the thrust plate 11 on the far right. The pressure plate cleaning component 2 starts to work, and the electric telescopic beam 1 pushes the pressure plate cleaning component 2 to the top of the gap. The electric lifting rod 3 starts to work and moves the fixed frame 201 downward to between the gaps. The electric rotating shaft 202 starts to rotate. During the rotation, the flushing water pipe 203 starts to fill with water and sprays it out from the water spray hole 204 and from the brush cover 205. The brush inside is flushed out onto the filter press plate 14 and the filter cloth 26, and the rotation of the electric rotating shaft 202 drives the transfer of the brush cover 205. The electric lifting rod 3 moves up and down, and the rotating brush cover 205 continuously brushes the filter press plate 14 and the filter cloth 26. The dehydrated filter press residue falls onto the rubber belt line 17. The rubber belt line 17 is continuously driven under the action of the rotating roller 16, and the residue on the surface is transferred to the outside of the filter press through the decontamination slope 21. After completing the cleaning of the first filter press plate 14 and the filter cloth 26, the horizontal slider 13 moves the second filter press plate 14 to the rightmost side for cleaning until all the sliders are cleaned;

[0025] Since the decontamination slope 21 is in contact with the rubber belt line 17, there is only a small gap between the sharp corner of the upper end of the decontamination slope 21 and the lower end of the rubber belt line 17, which is conducive to cleaning the rubber belt line 17 and preventing the surface of the rubber belt line 17 from being stuck by the residue dropped after the filtration. When the rubber belt line 17 is transmitted, the filtration residue attached to the surface will be scraped off by the sharp corner of the decontamination slope 21. At the same time, the electric rotating shaft 202 of the pressing plate cleaning component 2 rotates, driving the brush cover 205 to clean the filtration plate 14 and the filter cloth 26, thereby preventing the filtration residue from adhering to the surface of the filter cloth 26 and affecting the filtration of the next wheel.

[0026] like Figures 1 to 4As shown, a water-filled water tank 4 is installed at the lower end of the electric telescopic beam 1, and a water-filled water pipe 6 is provided on the right side of the water-filled water tank 4. A connecting water pipe 7 is connected to the outside of the water-filled water pipe 6. A control box 5 is installed at the lower end of the water-filled water tank 4, and an electric push rod 8 is installed at the end on the right side of the control box 5. A silt-filled crossbeam 9 is installed in the middle of the right side of the control box 5. A fixed rod 10 is provided on the outside of the electric push rod 8, and a thrust plate 11 is provided on the right side of the fixed rod 10. A pressure plate 11 is installed on the right side of the electric push rod 8. A filter plate 14 is provided, and a filter cloth 26 is provided on the outside of the filter plate 14. A filter water tank 18 is provided below the rubber belt line 17, and a positioning block 19 is installed on the side of the filter water tank 18. A filter screen 20 is provided on the inner side of the positioning block 19. A water outlet 25 is provided at the bottom of the side of the filter water tank 18. A filter open flow pipe 22 is installed on the left side of the filter plate 14, and a filter cotton 24 is provided inside the filter open flow pipe 22. A filter underflow pipe 23 is installed on the right side of the horizontal slider 13.

[0027] The specific operation is as follows: open the control box 5 and start the filter press. After starting, the electric push rod 8 on the right side of the control box 5 starts to push the filter press plate 14 wrapped with the filter cloth 26. The filter press plate 14 is fixed to the position by the fixing rod 10 and the silt filling beam 9. After being pushed to the thrust plate 11, the filter press plate 14 fits tightly. The silt inlet on the left side of the silt filling beam 9 is opened, and the fluid to be filtered is absorbed to fill the silt beam 9. The silt filling beam 9 continuously fills into the gap between the filter press plate 14. Under the squeezing of the electric push rod 8, the fluid between the filter press plates 14 is continuously squeezed out of water, and the squeezed water flows into the water filling tank 4 along the filter open flow pipe 22, and passes through the filter open flow on the way. After the filter cotton 24 provided in the tube 22 is squeezed out of the water through the gap, the connecting water pipe 7 starts to work, the lower end of the water filling tank 4 is connected to the water filling pipe 6, the water filling pipe 6 is opened, and the connecting water pipe 7 connected to the water filling pipe 6 fills the water in the water tank into the filter cloth 26, so that the filter cloth 26 swells due to the water filling, and the fluid is squeezed again. The squeezed water enters the filter water tank 18 along the filter undercurrent pipe 23 for filtration. On the way, it passes through the filter cotton 24 provided in the filter undercurrent pipe 23. After the squeezed water flows into the filter water tank 18, it is filtered by the filter mesh 20 fixed by the positioning block 19 for multi-layer filtration of the flowing liquid, and is discharged through the water outlet 25 after the filtration is completed.

[0028] Since the filter open flow pipe 22 and the filter dark flow pipe 23 are both provided with filter cotton 24, the squeezed water flow is filtered, which is beneficial to ensure that there will not be too much filter press residue in the water after squeezing, and the situation of filter press residue clogging the water pipe occurs. After the squeezed water is transported to the filter water tank 18, it undergoes multi-layer filtration to prevent the water from containing fine impurities that have not been filtered by the filter cotton 24, thereby ensuring the cleanliness of the water. At the same time, the filter open flow pipe 22 is connected to the water filling tank 4, and the water flow filtered in the filter open flow pipe 22 will be directly sent to the water filling tank 4 to fill the water in the filter cloth 26, which is beneficial to reduce resource waste and can be recycled.

[0029] In summary, the specific operations are as follows: open the control box 5 and start the filter press. After starting, the electric push rod 8 on the right side of the control box 5 begins to push the filter press plate 14 wrapped with the filter cloth 26. The filter press plate 14 is fixed to the position by the fixing rod 10 and the silt filling beam 9. After being pushed to the thrust plate 11, the filter press plate 14 fits tightly. The silt inlet on the left side of the silt filling beam 9 is opened, and the fluid to be filtered is absorbed to fill the silt beam 9. The silt filling beam 9 continuously fills into the gap between the filter press plates 14. Under the squeezing of the electric push rod 8, the fluid between the filter press plates 14 is continuously squeezed out of water, and the squeezed water flows into the water filling tank 4 along the filter open flow pipe 22, and passes through the filter on the way. After the filter cotton 24 provided in the open flow pipe 22 is squeezed out of the water through the gap, the connecting water pipe 7 starts to work, the lower end of the water filling tank 4 is connected to the water filling pipe 6, the water filling pipe 6 is opened, and the connecting water pipe 7 connected to the water filling pipe 6 fills the water in the water tank into the filter cloth 26, so that the filter cloth 26 swells due to the water filling, and the fluid is squeezed again. The squeezed water enters the filter water tank 18 along the filter undercurrent pipe 23 for filtration. On the way, it passes through the filter cotton 24 provided in the filter undercurrent pipe 23. After the squeezed water flows into the filter water tank 18, it is filtered by the filter mesh 20 fixed by the positioning block 19 for multi-layer filtration of the flowing liquid, and is discharged through the water outlet 25 after the filtration is completed.

[0030] After the filtration is completed, the electric push rod 8 retracts, and drives the filter press plate 14 to retract to the far left. The lower end of the side of the filter press plate 14 is installed with a slider transport block 15, and a horizontal slide rail 12 is provided below. The horizontal slider 13 straightens the first pressure plate on the far right and fits the thrust plate 11 on the far right. The pressure plate cleaning component 2 starts to work, and the electric telescopic beam 1 pushes the pressure plate cleaning component 2 to the top of the gap. The electric lifting rod 3 starts to work and moves the fixed frame 201 downward to between the gaps. The electric rotating shaft 202 starts to rotate. During the rotation, the inside of the flushing water pipe 203 begins to fill with water and sprays out from the water spray hole 204. The brush from the brush sleeve 205 The inside is flushed out onto the filter press plate 14 and the filter cloth 26, and the rotation of the electric rotating shaft 202 drives the transfer of the brush cover 205. The electric lifting rod 3 moves up and down, and the rotating brush cover 205 continuously brushes the filter press plate 14 and the filter cloth 26. The dehydrated filter press residue falls onto the rubber belt line 17, and the rubber belt line 17 is continuously driven under the action of the rotating roller 16, and the residue on the surface is transferred to the outside of the filter press through the decontamination slope 21. After completing the cleaning of the first filter press plate 14 and the filter cloth 26, the horizontal slider 13 moves the second filter press plate 14 to the far right for cleaning until all the sliders are cleaned.
