Description

Technical Field

[0001] This utility model relates to the field of filter equipment technology, and in particular to an improved stacked brush filter material fixing structure. Background Technology

[0002] Existing rotary filters use a reducer to drive a central tube, allowing the filter media fixed to the central tube to be circumferentially sprayed. However, the cleaning effect is still not thorough enough, leaving room for improvement. Patent publication CN217959160U discloses a solution: one end of the central tube is connected to a reducer. The reducer's rotation drives the filter media to rotate, and the brush, first pressure ring, and second pressure ring all rotate with the central tube. Inside the filter cylinder, there is a workpiece that abuts against the end of the brush. The part of the brush protruding from the filter media is blocked by the workpiece welded to the inner wall of the filter cylinder, preventing it from rotating. In this way, the filter media rotates while the brush is fixed. After one rotation, the filter media is in contact with the brush all the way around, achieving cleaning of the filter media. The cleaning effect is more thorough than existing technologies. This solution can effectively and thoroughly clean the filter element, but it has a problem: after the filter element and brush assembly end on the central tube are fastened by the annular pressure plate and clamps, this end of the central tube is then connected to the reducer. As a result, if the annular pressure plate and clamps become loose, these components will directly abut against the rotating ring and other components on the central tube that cooperate with the reducer, leading to equipment failure. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the main purpose of this utility model is to provide a solution to the equipment damage caused by inadequate clamping or loose fastening components in the existing technology.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an improved stacked brush filter media fixing structure, comprising a central tube, on which multiple filter sheets and brushes are spaced apart; the central tube includes a fixed end connected to a speed reducer and a connecting end inserted into the bottom of a filter barrel; a fixing ring is fixedly fitted on the central tube near the fixed end; and a moving ring assembly cooperating with the speed reducer is provided on the central tube at the fixed end; the multiple filter sheets and brushes are fitted onto the central tube from the connecting end; and the central tube also has a connecting end... A tapered connector is welded to the central tube. A fastening assembly is provided on the connector end. The fastening assembly includes a filter media pad, a sealing gasket, and a pad that are sequentially fitted onto the central tube. The filter media pad abuts against the outermost brush. The tapered connector includes a threaded section and a tapered section. A pin is inserted through the tapered section. The fastening assembly also includes a top-tightening plate that passes through the tapered section and is threaded onto the threaded section. The top-tightening plate is provided with a plurality of threaded holes, each of which is provided with a top-tightening screw that can abut against the pad.

[0005] Preferably, the moving ring assembly includes a moving ring sleeved on the central tube from the fixed end, a lower sealing ring of the moving ring, a top plate of the sealing ring, and a compression spring, wherein the compression spring abuts against the fixed ring.

[0006] Preferably, the diameter of the threaded section is smaller than the length of the pin, and two symmetrical pin slots are provided on the threaded through hole of the clamping plate.

[0007] Preferably, the diameter of the threaded section is greater than the length of the pin.

[0008] This invention has the following advantages over existing technologies: The fixing plate is welded to the central tube, and a tapered connector is welded to the connecting end of the central tube. The other end, the fixed end, is connected to the reducer via a rotating ring assembly. During assembly, first, the brush and brush pads are placed into the central tube from the connecting end, fitting snugly against the fixing ring. Then, the filter disc is placed in, followed by the sequential placement of all brush pads and brushes (filter discs). After placement, the filter media pad is placed in, followed by the sealing gasket. The tightening plate is then screwed onto the tapered connector, and the tightening screws are tightened diagonally until all screws are tightened. The rotating ring assembly is then sequentially installed into the fixed end. This completes the filter media assembly. The entire filter media set is then placed into the filter barrel, where the tapered connector at the connecting end aligns with the bottom of the filter barrel, and a pin provides a limiting position. This design, assembling the filter discs and brushes from the connecting end, solves the problem of equipment damage caused by inadequate tightening or loose fasteners in existing technologies.

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] like Figure 1 As shown, an improved composite brush 3 filter media fixing structure includes a central tube 1. Multiple filter sheets 2 and brushes 3 are spaced and sleeved on the central tube 1. The central tube 1 includes a fixed end 4 connected to a speed reducer and a connecting end 5 inserted into the bottom of the filter barrel. A fixing ring 6 is fixedly sleeved on the central tube 1 near the fixed end 4. A moving ring assembly 7 cooperating with the speed reducer is provided on the central tube 1 at the fixed end 4. The multiple filter sheets 2 and brushes 3 are sleeved onto the central tube 1 from the connecting end 5. A tapered connector 8 is also welded to the central tube 1 at the connecting end 5. A fastening assembly 9 is provided on end 5. The fastening assembly 9 includes a filter media pad 10, a sealing gasket 11, and a pad 12 that are sequentially sleeved on the central tube 1. The filter media pad 10 abuts against the outermost brush 3. The tapered connector 8 includes a threaded section 13 and a tapered section 14. A pin 15 is provided on the tapered section 14. The fastening assembly 9 also includes a top-tightening plate 16 that passes through the tapered section 14 and is threadedly connected to the threaded section 13. The top-tightening plate 16 is provided with a plurality of threaded holes, and a top-tightening screw 18 that can abut against the pad is provided in each of the plurality of threaded holes.

[0016] This solution presents an improved filter media fixing structure for stacked brushes 3. A fixing plate is welded to the central tube 1. A tapered connector 8 is welded to the connecting end 5 of the central tube 1, and the other end, the fixing end 4, is connected to the reducer via a rotating ring assembly 7. During assembly, first, the brushes 3 and brush 3 pads are inserted into the central tube 1 from the connecting end 5, fitting snugly against the fixing ring 6. Then, the filter disc 2 is placed in. Next, all the brush 3 pads and brushes 3 (i.e., filter discs 2) are placed in sequence. After placement, the filter media pad 10 is placed in, followed by the sealing gasket 11 (i.e., pad 12). Then, the tightening plate 16 is tightened onto the tapered connector 8. The tightening screws 18 are then tightened diagonally until all screws 18 are tightened. Finally, the rotating ring assembly 7 is installed into the fixing end 4. This completes the filter media assembly. The entire filter media set is then placed into the filter canister. The tapered connector 8 at the connecting end 5 aligns with the bottom of the filter canister, and a pin provides a limiting position. This solution assembles the filter element 2 and brush 3 from the connection end 5, which can solve the problem of equipment damage caused by insufficient clamping or loose fastening components 9 in the prior art.

[0017] Preferably, the rotating ring assembly 7 includes a rotating ring 19, a lower rotating ring sealing ring 20, a sealing ring top plate 21, and a compression spring 22, which are sleeved on the central tube 1 from the fixed end 4. The compression spring 22 abuts against the fixed ring 6. After the rotating ring 19, the lower rotating ring sealing ring 20, the sealing ring top plate 21, and the compression spring 22 are assembled, they are connected to the reducer.

[0018] Preferably, the diameter of the threaded section 13 is smaller than the length of the pin 15, and two symmetrical pin grooves 23 are provided on the threaded through hole of the clamping plate 16.

[0019] Preferably, the diameter of the threaded section 13 is greater than the length of the pin 15.

[0020] The tensioning plate 16 has two structural designs, determined by the diameter of the threaded section 13 and the length of the pin 15. When the diameter of the threaded section 13 is less than the length of the pin 15, two symmetrical pin grooves 23 extend from the threaded through hole of the tensioning plate 16, ensuring that the tensioning plate 16 can smoothly pass through the tapered connector 8. When the diameter of the threaded section 13 is greater than the length of the pin 15, the threaded through hole of the tensioning plate 16 is a complete circular structure.

[0021] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
