Description

Technical Field

[0001] The invention relates to the technical field of diaphragm filter presses, and in particular to a device for removing accumulated mud from a central hole of a diaphragm filter press. Background Art

[0002] The diaphragm filter press is mainly composed of four parts: the frame, the hydraulic system, the filter part and the electrical control part. When the diaphragm filter press is working, the piston in the oil cylinder pushes the compression plate, which compresses the filter plate and filter medium between the compression plate and the thrust plate to ensure that the filtered material with working pressure is pressurized and filtered in the filter chamber.

[0003] During the dehydration process, sludge with high water content will remain in the center hole of the filter press. This sludge will be pushed into the sludge pool during the unloading process, which will increase the water content of the filtered sludge and cause the quality of the sludge to decrease after filtration. Therefore, the center hole of the filter press needs to be cleared of sludge before unloading. Summary of the Invention

The driving part 2 is fixedly connected to the moving end of the pushing hydraulic rod 1, the adaptive cleaning head 3 is fixedly connected to the driving part 2, the adaptive cleaning head 3 is provided with a guide head 4, the adaptive cleaning head 3 is slidably connected to the connecting pipe 5, the connecting pipe 5 is fixedly connected to the filter plate 6, and a stop valve is provided on the connecting pipe 5. The adaptive cleaning head 3 can change the outer diameter size and the adaptive cleaning head 3 can rotate around its own central axis. When in use, the stop valve on the connecting pipe 5 is opened to enable the adaptive cleaning head 3 to move in and out. Enter the center hole of the filter plate 6, and use the pushing hydraulic rod 1 to push the driving part 2 and the adaptive cleaning head 3 together. After the driving part 2 and the adaptive cleaning head 3 enter the center hole of the filter plate 6, start the driving part 2. The driving part 2 drives the adaptive cleaning head 3 to adjust the outer diameter so that the adaptive cleaning head 3 can contact the hole wall of the center hole of the filter plate 6. Then the driving part 2 drives the adaptive cleaning head 3 to rotate along the central axis. During the rotation, the cleaning head 3 cleans the inner wall of the center hole. During the cleaning process, the hydraulic rod 1 is pushed, which can push the cleaned sludge forward until the accumulated sludge is pushed out of the center hole and falls into the sludge pool.

[0035] Preferably, the driving part 2 includes a telescopic closed shell 21, a driving cleaning motor 22, a cleaning head adjustment motor 23, a driving gear 24 and a driven gear 25. The driving cleaning motor 22 and the cleaning head adjustment motor 23 are both fixedly connected to the telescopic closed shell 21. The driving gear 24 is fixedly connected to the output shaft of the driving cleaning motor 22. The driving gear 24 and the driven gear 25 are engaged for transmission. The adaptive cleaning head 3 includes an adjustment screw 31, a driving shaft 32, a driving shaft gear 321, a counter-rotating shaft 33, a counter-rotating transmission gear 331, a transmission gear 34, a closed expansion ring 35 and a sealing push upper card plate 36. The sealing push upper card plate 36 is threadedly driven with the adjusting screw 31, and the sealing push upper card plate 36 is rotatably connected to the telescopic closed shell 21. The driven gear 25 is fixedly connected to the driving shaft 32, the counter-rotating transmission gear 331 is fixedly connected to the counter-rotating shaft 33, and the driving shaft gear 321 is fixedly connected to the driving shaft 32. The driving shaft gear 321 and the counter-rotating transmission gear 331 are meshed and transmitted through multiple transmission gears 34. The driving shaft 32 rotates and is connected to the counter-rotating shaft 33. The driving cleaning motor 22 is started to drive the driving gear 24 to rotate, and the driven gear 25 meshed with it also rotates, driving the driving shaft gear 321 to rotate. The driving shaft gear 321 drives multiple transmission gears 34 to rotate, causing the counter-rotating transmission gear 331 to rotate, thereby realizing the reverse synchronous rotation of the driving shaft 32 and the counter-rotating shaft 33, so that the cleaning head 3 can continuously rotate in the center hole to clean, clean up and push out the accumulated mud.

[0036] Preferably, the adaptive cleaning head 3 further comprises an elastic conical expansion ring 35, a bottom sand pushing ring 351, a telescopic axial limiting ring 352 and a pushing lower card plate 353. The elastic conical expansion ring 35 is arranged between the pushing lower card plate 353 and the sealing pushing upper card plate 36. The telescopic axial limiting ring 352 is fixedly connected to the bottom of the sealing pushing upper card plate 36. A plurality of transmission gears 34 are rotatably connected to the telescopic axial limiting ring 352. The bottom sand pushing ring 351 is fixedly connected to the anti-rotation shaft 33. The cleaning head adjustment motor 23 starts the adjustment screw 31 to rotate. Pushed by the thread, the sealing push upper clamping plate 36 moves downward on the adjusting screw 31, generating pressure on the elastic conical expansion ring 35, causing the elastic conical expansion ring 35 to expand, thereby increasing the maximum outer diameter, so that it contacts the hole wall of the center hole of the filter plate 6 to prevent sludge residue during the pushing process. When the elastic conical expansion ring 35 is shortened, the telescopic axial limiting ring 352 also becomes shorter. The telescopic axial limiting ring 352 provides a rotation position for multiple transmission gears 34, and multiple transmission gears 34 are slidingly connected to the telescopic axial limiting ring 352.

[0037] Preferably, a card slot 361 is provided at the bottom of the sealing push upper card plate 36, and the card slot 361 can provide a deformation support surface for the deformation of the elastic conical expansion ring 35, thereby producing a size that can adapt to various apertures.

[0038] Preferably, the cone angles of the elastic conical expansion ring 35 on the upper and lower sides are 30° and 60° respectively, which can ensure that the elastic conical expansion ring 35 opens outward when subjected to force, and ensures that the elastic conical expansion ring 35 will not pop out of the slot 361 under the premise that the elastic conical expansion ring 35 is compressed to the maximum range, thereby causing the device to fail.

[0039] Preferably, the adaptive cleaning head 3 further includes an adjustment motor 301, an adjustment end plate 37, a fixed end plate 371, a connecting rod 38, a slider 39, a horizontal connecting rod 310, an extension push rod 311 and a cleaning rotating shell 313, the adjustment motor 301 output shaft is fixedly connected to the adjustment end plate 37, the adjustment end plate 37 is fixedly connected to the cleaning rotating shell 313, the cleaning rotating shell 313 is fixedly connected to the bottom sand pushing ring 351, multiple connecting rods 38 are fixedly connected to the adjustment end plate 37, multiple horizontal connecting rods 310 are respectively rotatably connected to the multiple connecting rods 38, and multiple horizontal connecting rods 310 are fixedly connected to the multiple connecting rods 38. They are rotatably connected to multiple sliders 39 respectively, and extension push rods 311 are fixed to multiple sliders 39. Multiple sliders 39 are slidably connected to the fixed end plate 371, and the fixed end plate 371 is fixed to the cleaning rotating shell 313. Multiple extension push rods 311 are slidably connected to the cleaning rotating shell 313. The adjustment motor 301 is fixed to the cleaning rotating shell 313. When the adjustment motor 301 is started, the adjustment end plate 37 rotates, and the multiple connecting rods 38 rotate, pushing the sliders 39 to slide on the fixed end plate 371, and pushing the multiple extension push rods 311 to achieve diameter change.

[0040] Preferably, the adaptive cleaning head 3 also includes an extended cleaning plate 312 and a cleaning scraper 314, and a plurality of cleaning scrapers 314 are fixedly connected to the extended cleaning plate 312, and the plurality of extended cleaning plates 312 are respectively fixedly connected to a plurality of extended push rods 311, and the plurality of extended cleaning plates 312 are all slidably connected to the cleaning rotating shell 313, and the plurality of cleaning scrapers 314 are in a "V" shape. When the plurality of extended cleaning plates 312 rotate, the "V"-shaped cleaning scraper 314 can remove the sludge in the center hole, increase the contact area with the sludge, and make it more convenient to remove the sludge. In the process of cleaning long-distance holes, the plurality of cleaning scrapers 314 can move the two sludge storages to prevent excessive sludge from being retained, causing the sludge to be stuck.
