DETAILED DESCRIPTION

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] See also Figure 1-4 The utility model provides a technical solution: an electronic slurry filtering device, comprising a filter box 1 and a filter cartridge 3 that passes through from top to bottom.

The semicircular protrusion 27 is connected to the lower end of the adjacent support plate 6. The semicircular impact block 26 corresponds to the semicircular protrusion 27. The upper end of the filter box 1 is connected to the feed hopper 2.

[0023] When the electronic slurry is filtered through the filtering device, the electronic slurry is added to the filter cylinder 3 through the feed hopper 2. When the electronic slurry is filtered through the conical filter screen 9, the rotating shaft 25 and the semicircular impact block 26 are driven to rotate together by the operation of the rotating motor 24. The semicircular impact block 26 will continuously push the semicircular protrusion 27 and the support plate 6 upward through the arc surface. The support plate 6 will compress the spring return rod 5, and then the elastic force of the spring return rod 5 will drive the support plate 6 to move down and reset. In this way, the filter cylinder 3 and the conical filter screen 9 can be driven to vibrate up and down together, so that the electronic slurry is vibrated through the conical filter screen 9. Compared with the static filtration method, the filtration efficiency of the electronic slurry is effectively improved.

[0024] In this embodiment, the upper end of the lower shaft tube 11 is connected to a telescopic tube 16, the upper end of the telescopic tube 16 is connected to the upper shaft tube 10, and the upper ends of the left and right sides of the lower shaft tube 11 are fixed with spring telescopic rods 12, and the upper ends of the spring telescopic rods 12 are fixed to the outside of the lower shaft tube 11.

[0025] When the filter cartridge 3 and the conical filter screen 9 vibrate up and down, the conical filter screen 9 will drive the upper shaft tube 10 to move up and down together. At this time, the upper shaft tube 10 will stretch the telescopic tube 16 and the spring telescopic rod 12 up and down, thereby ensuring the normal up and down vibration of the conical filter screen and the filter cartridge 3.

[0026] In this embodiment, a liquid storage chamber 17 is opened at the lower end of the filter box 1, and a mounting chamber 18 is opened at the front end of the filter box 1 above the liquid storage chamber 17. A water pump 19 communicating with the liquid storage chamber 17 is installed in the mounting chamber 18. The upper end of the water pump 19 is rotatably connected and communicated with a lower shaft tube 11. The lower shaft tube 11 rotates upward to penetrate into the filter box 1, and the upper end of the lower shaft tube 11 is connected with a telescopic tube 16. The upper end of the telescopic tube 16 is connected with an upper shaft tube 10. The upper ends of the left and right sides of the lower shaft tube 11 are fixed with spring telescopic rods 12. The upper ends of the spring telescopic rods 12 are fixed to the outside of the lower shaft tube 11. The upper shaft tube 10 rotates upward to penetrate the conical filter screen 9. The conical filter screen 9 is provided with a cleaning pipe 13, a cleaning brush 15 and several flushing nozzles 14 on the left side of the upper end and the right side of the lower end. The cleaning pipes 13 are connected to the upper shaft tube 11, and the cleaning brushes 15 are connected to the inner side of the cleaning pipe 13. The flushing nozzles 14 are connected to the inner side of the cleaning pipe 13. A rotary drive assembly is provided in the mounting cavity 18. The rotary drive assembly includes a drive motor 20, a drive gear 21 and a driven gear 22. The drive motor 20 is fixed in the mounting cavity 18, and the drive gear 21 is connected to the power end of the drive motor 20. The driven gear 22 is fixedly sleeved on the outer periphery of the lower shaft tube 11, and the driven gear 22 is engaged with the drive gear 21.

[0027] When it is necessary to clean the upper and lower end surfaces of the conical filter 9, the cleaning brushes 15 at the upper and lower ends are respectively arranged to be in contact with the upper and lower end surfaces of the conical filter 9. Therefore, the driving gear 21, the driven gear 22, the lower shaft tube 11, the spring telescopic rod 12, the telescopic tube 16, the upper shaft tube 10, the cleaning tube 13, the cleaning brush 15 and the flushing nozzle 14 are rotated together by the working of the driving motor 20. The rotating cleaning brush 15 will sweep and clean the upper and lower end surfaces of the conical filter 9, and under the premise that the cleaning liquid is stored in the liquid storage chamber 17, the cleaning liquid is pumped into the lower shaft tube 11, the telescopic tube 16, the upper shaft tube 10 and the flushing nozzle 14 in sequence through the work of the water pump 19, and finally the cleaning liquid is sprayed onto the upper and lower end surfaces of the conical filter 9 by the flushing nozzle 14, thereby achieving the effect of flushing and cleaning the conical filter 9. In summary, there is no need to frequently disassemble and assemble to clean and dredge the conical filter 9, so it is convenient to clean and dredge the conical filter 9.

[0028] In this embodiment, the left side of the filter box 1 is connected to a discharge valve 23, and the right side of the filter cylinder 3 is connected to a waste valve 7 close to the outer edge of the conical filter screen 9. The waste outlet of the waste valve 7 is connected to a waste hose 8, and the end of the waste hose 8 passes through the outside of the filter box 1.

[0029] When the electronic slurry is filtered to the bottom of the filter box 1, the filtered electronic slurry can be discharged by opening the discharge valve 23. When the conical filter 9 is cleaned and the electronic slurry in the filter box 1 is discharged cleanly, the waste liquid generated by cleaning and dredging is discharged through the discharge valve 23, and the waste valve 7 is opened. The waste liquid above the conical filter 9 is discharged through the waste valve 7 and the waste hose 8, so that the conical filter 9 can be used normally later.

[0030] Working principle:

[0031] The electronic slurry is added into the filter cylinder 3 through the feed hopper 2, and the rotating shaft 25 and the semicircular impact block 26 are driven to rotate together by the work of the rotating motor 24. The semicircular impact block 26 will continuously push the semicircular protrusion 27 and the support plate 6 upward through the arc surface, and the support plate 6 will compress the spring return rod 5, and then the elastic force of the spring return rod 5 drives the support plate 6 to move down and reset, so as to reciprocate, thereby vibrating and filtering the electronic slurry through the conical filter 9. When the upper and lower end surfaces of the conical filter 9 need to be cleaned, the upper and lower end surfaces of the conical filter 9 are cleaned by driving the drive cam 26. The working drive gear 21, the driven gear 22, the lower shaft tube 11, the spring telescopic rod 12, the telescopic tube 16, the upper shaft tube 10, the cleaning tube 13, the cleaning brush 15 and the flushing nozzle 14 of the driving motor 20 rotate together. The rotating cleaning brush 15 will sweep and clean the upper and lower end surfaces of the conical filter 9, and then the cleaning liquid will be pumped into the lower shaft tube 11, the telescopic tube 16, the upper shaft tube 10 and the flushing nozzle 14 in turn through the work of the water pump 19, and finally the cleaning liquid will be sprayed onto the upper and lower end surfaces of the conical filter 9 by the flushing nozzle 14.
