Description

Technical Field

[0001] This utility model relates to the field of feed pump technology, and more specifically, to an anti-clogging feed pump. Background Technology

[0002] Currently, feed pumps commonly face clogging problems when conveying materials containing particles (such as mine drainage), leading to decreased efficiency, increased energy consumption, and even equipment damage. The main drawbacks of existing technologies include reliance on filters and frequent maintenance.

[0003] A fixed filter screen (such as a bar screen or metal mesh) is usually installed at the water inlet to intercept impurities. However, if the filter screen pore size is too large, fine fibers will pass through, while if the pore size is too small, it will be easily clogged. Cleaning the filter screen requires frequent shutdowns and disassembly, which affects continuous operation. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a non-clogging feed pump that is easy to clean.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An anti-clogging feed pump includes a pump body, a filter cylinder connected to the feed side of the pump body, a filter screen disposed inside the filter cylinder, an anti-clogging mechanism disposed on the side of the filter screen facing the pump body, and a collection box disposed on the side of the filter screen away from the pump body. Mounting brackets are disposed at both ends of the filter cylinder, and the two mounting brackets are rotatably connected to a rotating shaft. The rotating shaft passes through the filter screen, and the anti-clogging mechanism and the collection box are both fixed on the rotating shaft. The position of the anti-clogging mechanism corresponds to that of the collection box.

[0007] The present invention is further configured such that: the unclogging mechanism includes a mounting plate, the mounting plate is fixed on a rotating shaft, the surface of the mounting plate is slidably connected to the filter screen, the filter screen is evenly provided with a plurality of mesh holes, the mounting plate is provided with a plurality of through holes, the positions of the through holes correspond to the positions of the mesh holes, a push block is slidably connected in the through hole, the push block can extend into the mesh hole, one end of the push block away from the filter screen extends out of the through hole, and one end of the push block extending out of the through hole is provided with a top plate, the top plate can abut against the mounting plate.

[0008] The present invention is further configured such that: a sealing film is covered on the top plate, the edge of the sealing film is fixed to the mounting plate, and the sealing film seals the through hole.

[0009] The present invention is further configured such that: the end of the push block away from the sealing film is provided with a tip, the tip is wedge-shaped, the top end of the wedge-shaped tip can extend into the mesh, the bottom end of the wedge-shaped tip is always in the through hole, and the wedge-shaped surface of the tip faces the preset rotation direction of the mounting plate.

[0010] The present invention is further configured such that: the filter cylinder includes a cylinder body, one end of the cylinder body away from the pump body is a feed inlet, the other end of the cylinder body is a discharge outlet, one side of the collection box is provided with an opening, the opening of the collection box is a receiving groove, the side wall of the collection box with the receiving groove is in contact with the filter screen, and the side wall of the collection box away from the receiving groove is provided with a spiral surface, the spiral surface facing the feed inlet.

[0011] The advantages of this utility model are:

[0012] 1. A cleaning mechanism and a collection box are respectively set on both sides of the filter screen. When the push block of the cleaning mechanism moves to the mesh of the filter screen, the top plate and the sealing membrane are pushed to the collection box side under the action of hydraulic pressure, so that the push block extends into the mesh and pushes the impurities in the mesh into the collection box. The collection box fits into the filter screen. A mounting plate is attached to the corresponding position on the other side of the filter screen, so that there is almost no liquid flow in the collection box. The impurities pushed into the collection box will no longer block the mesh with the liquid flow, thereby cleaning the filter screen and preventing clogging.

[0013] 2. A rotating shaft is connected inside the filter cartridge. The unclogging mechanism and the collection box are fixed on the rotating shaft. The side wall of the collection box facing the feed inlet is set as a spiral surface. When the feed passes through the collection box, it will push the collection box to rotate through the spiral surface, and at the same time drive the unclogging mechanism to rotate, thus cleaning. When the flow rate increases, impurities are more likely to clog the mesh, while the rotation speed of the collection box increases and the cleaning frequency increases, ensuring the smooth flow of the filter screen.

[0023] Please see Figure 1-5 The present invention provides the following technical solution:

[0024] A clog-resistant feed pump includes a pump body 1, a filter cylinder 2 connected to the feed side of the pump body 1, a filter screen 3 inside the filter cylinder 2, a clogging removal mechanism 4 on the side of the filter screen 3 facing the pump body 1, and a collection box 5 correspondingly located on the side of the filter screen 3 away from the pump body 1. Mounting brackets 7 are located at both ends of the filter cylinder 2, and the two mounting brackets 7 are rotatably connected to a rotating shaft 6. The rotating shaft 6 passes through the filter screen 3, and the clogging removal mechanism 4 and the collection box 5 are both fixed on the rotating shaft 6. The position of the clogging removal mechanism 4 corresponds to that of the collection box 5. When the pump body 1 is started, the liquid flow pushes the collection box 5, thereby driving the clogging removal mechanism 4 to rotate synchronously. When the clogging removal mechanism 4 rotates, it can push impurities on the filter screen 3 at the corresponding position into the collection box 5 for collection, thereby cleaning the filter screen 3 and preventing clogging.

[0025] The unclogging mechanism 4 includes a mounting plate 41, which is fixed on the rotating shaft 6. The surface of the mounting plate 41 is slidably connected to the filter screen 3. The filter screen 3 has a plurality of mesh holes 31 evenly distributed through it. The mounting plate 41 has a plurality of through holes 42 distributed through it. The positions of the through holes 42 correspond to the positions of the mesh holes 31. A push block 43 is slidably connected inside the through hole 42. The push block 43 can extend into the mesh hole 31. One end of the push block 43 away from the filter screen 3 extends out of the through hole 42. A top plate 45 is provided at one end of the push block 43 extending out of the through hole 42. The top plate 45 can abut against the mounting plate 41. A sealing film 46 is covered on the top plate 45. The edge of the sealing film 46 is fixed on the mounting plate 41. The sealing film 46 seals and covers the through hole 42.

[0026] Under the action of hydraulic pressure, the sealing membrane 46 and the top plate 45 tend to move towards the filter screen 3. When the through hole 42 moves to the position corresponding to the mesh 31, the pusher 43 is pushed by the sealing membrane 46 and the top plate 45 to extend into the mesh 31, thereby pushing the impurities in the mesh 31 into the collection box 5.

[0027] The push block 43 has a pointed tip 44 at the end away from the sealing film 46. The pointed tip 44 is wedge-shaped, and the top of the wedge-shaped tip 44 can extend into the mesh 31. The bottom of the wedge-shaped tip 44 is always in the through hole 42. The wedge-shaped surface of the pointed tip 44 faces the preset rotation direction of the mounting plate 41. The push block 43 extends into the mesh 31. When the mounting plate 41 rotates, it drives the push block 43 to rotate synchronously. The wedge-shaped surface of the pointed tip 44 abuts against the edge of the mesh 31, thereby pushing the push block 43 to move away from the filter screen 3, which facilitates continuous cleaning operations.

[0028] The filter cartridge 2 includes a cylinder 21. One end of the cylinder 21 facing away from the pump body 1 is the inlet 22, and the other end of the cylinder 21 is the outlet 23. The collection box 5 has an opening on one side, which is a receiving groove 51. The side wall of the collection box 5 with the receiving groove 51 is in contact with the filter screen 3. The side wall of the collection box 5 facing away from the receiving groove 51 is set as a spiral surface 52. The spiral surface 52 faces the inlet 22. When the liquid flows through the spiral surface 52, it will create a radial thrust on the spiral surface 52, thereby driving the collection box 5 to rotate. The greater the liquid flow rate, the greater the rotation speed of the collection box 5.

[0029] Specifically, a cleaning mechanism 4 and a collection box 5 are respectively provided on both sides of the filter screen 3. When the push block 43 of the cleaning mechanism 4 moves to the mesh 31 of the filter screen 3, the top plate 45 and the sealing film 46 are pushed towards the collection box 5 under the action of hydraulic pressure, so that the push block 43 extends into the mesh 31 and pushes the impurities in the mesh 31 into the collection box 5. The collection box 5 is attached to the filter screen 3. The mounting plate 41 is attached to the corresponding position on the other side of the filter screen 3, so that there is almost no liquid flow in the collection box 5. The impurities pushed into the collection box 5 will no longer be blocked on the mesh 31 with the liquid flow, thereby achieving the cleaning of the filter screen 3 and preventing clogging.

[0030] A rotating shaft 6 is rotatably connected inside the filter cartridge 2. The unclogging mechanism 4 and the collection box 5 are both fixed on the rotating shaft 6. The side wall of the collection box 5 facing the feed inlet 22 is set as a spiral surface 52. When the feed passes through the collection box 5, it will push the collection box 5 to rotate through the spiral surface 52, and at the same time drive the unclogging mechanism 4 to rotate, thereby cleaning. When the flow rate increases, impurities are more likely to clog the mesh 31. At the same time, the rotation speed of the collection box 5 increases and the cleaning frequency increases, ensuring the smooth flow of the filter screen 3.
