[0016] Compared with the prior art, the present invention provides a paint sludge reduction filtration and separation device, which has the following beneficial effects:

[0017] 1. The newly added structure on the sweeping plate works in conjunction with the clamping plate and the pressing airbag to cause paint residue to accumulate at the end of the drive chain and flow back to the reduction chamber, reducing paint residue residue. During movement, the airbag is pressurized and sprays liquid or gas to generate thrust, quickly pushing the paint residue away to the other end of the baffle, accelerating paint residue separation. Compared with traditional devices, this greatly shortens the processing time and increases the amount of paint residue processed per unit time.

[0018] 2. The thrust generated by the pressing airbag on the water surface precisely acts on the paint residue, effectively separating it from other substances for a more thorough separation. Spring reset and sleeve rod guidance ensure stable airbag operation, guaranteeing a consistent fluid ejection with each squeeze, steadily pushing the paint residue away, improving separation accuracy, and yielding a purer processed product.

[0019] 3. The spring's restoring deformation resets the pressing airbag, ensuring continuous and stable operation of the device and preventing subsequent operations from being affected by the airbag's inability to reset. The sleeve guides the pressing direction of the pressing airbag, ensuring that the round head is always aligned with both ends of the sweeping plate, preventing structural damage due to uneven force, extending equipment lifespan, reducing maintenance frequency, and lowering maintenance costs.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides, for example Figure 1-4 The paint sludge reduction filtration and separation device shown includes a reduction device body 1 and a feed hopper 2 located on the outside of the right side of the reduction device body 1.

[0027] A fixed support frame 3 is provided on the lower side of the main body 1 of the reduction equipment, a motor box 11 is provided on the front exterior of the main body 1 of the reduction equipment, a reduction cavity 4 is provided on the middle inner side of the main body 1 of the reduction equipment, a separation cavity 5 is provided on the left side of the reduction cavity 4, and a baffle 6 is provided at the middle position of the reduction cavity 4 and the separation cavity 5.

[0028] A drive shaft 8 is provided at the upper left and right ends of the reduction chamber 4, and a drive chain 9 is provided on the front and rear sides of the drive shaft 8, and a sweeping plate 10 is provided on the outer side of the two drive chains 9.

[0029] In this embodiment, when the paint sludge reduction and filtration separation device is running, it mainly revolves around a series of operations performed by the drive chain 9 driving the sweeping plate 10. After the drive chain 9 is started, it drives the sweeping plate 10 to move cyclically along a set path, passing through different working areas in sequence, thereby realizing the collection, separation and reduction of paint sludge.

[0030] The sweeping plate 10 moves with the drive chain 9, cleaning and collecting the paint residue as it passes through areas where it exists. When the sweeping plate 10 reaches the end of the drive chain 9 near the reduction chamber 4, a newly added structure on the sweeping plate 10 comes into play. The rounded heads 13 on both sides of the sweeping plate 10 squeeze and press the air bladder 16. As the sweeping plate 10 continues to move, some paint residue gradually accumulates during this process. Simultaneously, the air bladder 16 is compressed, and the internal liquid or gas is ejected from the nozzle 12. The resulting force pushes the accumulated paint residue back into the reduction chamber 4, achieving initial collection and return of the paint residue, preventing it from accumulating at the end and affecting equipment operation.

[0031] like Figure 1-4 As shown, a pressing airbag 16 is provided at both ends of the sweeping plate 10. A round head 13 is provided on the outside of the end of the pressing airbag 16. A fixing ring 14 is provided on the outside of the pressing airbag 16 and the outside of the round head 13. A spring 15 is provided in the middle of the two fixing rings 14. A sleeve rod 17 is provided at the upper and lower ends of the two fixing rings 14, and a limit block 18 is provided at one end of the sleeve rod 17.

[0032] A nozzle 12 is protruding from the upper right front of the sweeping plate 10, and two clamping plates 7 are respectively provided on the upper left side of the reduction chamber 4 near the right end of the baffle 6.

[0033] A one-way air inlet valve is provided at the left end of the press airbag 16. A space is provided at the connection between the nozzle 12 inside the sweeping plate 10 and the press airbag 16 to serve as a channel for gas or water media. The fixing ring 14 is connected to the sweeping plate 10 and the round head 13 via welding and connection methods. The spring 15 wraps around the press airbag 16 and releases elastic force towards the fixing rings 14 on both sides. The sweeping plate 10 is connected to the drive chain 9 via bolts. The drive chain 9 is connected to two drive shafts 8 via meshing connection. The drive shafts 8 are connected via transmission connection methods. The drive shaft 8 is connected to the motor housing 11 via a transmission, and one end of the drive shaft 8 is connected to the main body 1 of the reduction equipment via a nested connection. The clamping plate 7 is inclined, and the inclination angle gradually increases with the distance between the reduction chamber 4 and the separation chamber 5. One end of the sleeve rod 17 is welded to the fixing ring 14 on the side of the round head 13, and the other end passes through the fixing ring 14 on the other side. The round heads 13 at both ends of the sweeping plate 10 are in close contact with the inner wall of the reduction chamber 4. An arc-shaped transition area is designed at the contact point between the clamping plate 7 and the front of the round head 13. When the round head 13 contacts this area, it can smoothly transition to the inclined area of ​​the clamping plate 7.

[0034] Preferably, a clamping plate 7 structure is provided on the front side of the baffle 6 between the reducing chamber 4 and the separating chamber 5. When the sweeping plate 10 passes the clamping plate 7, the action of the round head 13 squeezing the pressing airbag 16 occurs again. After the pressing airbag 16 is squeezed, the internal liquid or gas is ejected from the nozzle 12, generating thrust on the water surface. This thrust pushes the paint residue away to the other end of the baffle 6, achieving preliminary separation of the paint residue from other liquids or impurities. During the process of pushing the paint residue away, due to the elastic action of the spring 15, after the pressing action of the pressing airbag 16 is completed, the spring 15 restores its deformation, resetting the pressing airbag 16 to its initial state, preparing it for the next squeezing.

[0035] In addition, the sleeve rod 17 plays a crucial auxiliary role throughout the process. It guides the pressing direction of the pressing airbag 16, ensuring that the orientation of the round head 13 is always consistent with the two ends of the sweeping plate 10's movement direction. This ensures that during the movement of the sweeping plate 10, the round head 13 can accurately squeeze and press the airbag 16, causing the airbag to stably spray liquid or gas, thereby stably pushing the paint sludge, improving the effect and stability of paint sludge reduction filtration and separation, and ensuring the continuous and efficient operation of the device.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
