[0003] Traditional coating additive extraction and filtration equipment uses specialized filter bags to remove solid particles from liquid coatings. This type of equipment is typically suitable for high-flow-rate coating production lines. During the filtration process, the coating additive fabric must fully cover the top of the filter bag; otherwise, it will result in waste of coating additives, reduced filtration efficiency, and decreased practicality of the equipment. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a coating additive extraction and filtration device, which aims to improve the problem of coating additive waste caused by the inability of the coating additive cloth to completely cover the top of the filter bag, and the low practicality of the device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a coating additive extraction and filtration device, comprising a filter barrel, a top cover threadedly connected to the top of the filter barrel, two mounting brackets slidably connected inside the filter barrel, filter bags fixedly connected to the bottom of each of the two mounting brackets, a water distribution mechanism provided inside the filter barrel for evenly distributing coating additives into the filter bags, and a locking mechanism provided outside the filter barrel for quickly replacing the filter bags;

[0006] The water distribution mechanism includes a drive motor, the output end of which is fixedly connected to the top of the top cover. The output end of the drive motor is fixedly connected to a connecting shaft, the bottom of which is fixedly connected to a crank. The bottom of the crank is rotatably connected to a U-shaped frame, the inside of which is rotatably connected to a pipe sleeve. The inside of the pipe sleeve is fixedly connected to a connecting pipe, and the bottom of the connecting pipe is fixedly connected to several spray pipes.

[0007] As a further description of the above technical solution:

[0008] One end of the connecting pipe is rotatably connected to the inside of the filter barrel.

[0009] As a further description of the above technical solution:

[0010] The bottom of the filter barrel is fixedly connected to a receiving hopper, and the bottom of the receiving hopper is provided with a receiving bin.

[0011] As a further description of the above technical solution:

[0012] The engaging mechanism includes four mounting shells, with the opposite sides of the four mounting shells fixedly connected to the outside of the filter barrel. A spring is fixedly connected inside the mounting shell, and a limiting block is fixedly connected to the side of the spring near the filter barrel. A pin is fixedly connected inside the limiting block, and the pin passes through the outside of the filter barrel and engages with the outside of the mounting frame.

[0013] As a further description of the above technical solution:

[0014] A fixing box is fixedly connected to the top of the mounting shell, a sliding plate is slidably connected inside the fixing box, a baffle plate is fixedly connected to the bottom of the sliding plate, and the bottom of the baffle plate abuts against the top of the limiting block.

[0015] As a further description of the above technical solution:

[0016] The limiting block is slidably connected inside the mounting housing.

[0017] As a further description of the above technical solution:

[0018] The pin passes through both ends of the mounting housing.

[0019] As a further description of the above technical solution:

[0020] A handle is fixedly connected to the side of the pin away from the limiting block.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, during filtration, the coating additive is conveyed through a connecting pipe to a spray pipe and sprayed into the filter bag for filtration. After filtration, it falls into a collection bin via a collection hopper. During the coating process, the drive motor is activated to drive the connecting shaft, which in turn drives the U-shaped frame via a crank, causing the sleeve to swing back and forth inside the filter bin. The coating additive is then evenly sprayed into the filter bag through the spray pipe, achieving a uniform distribution of the coating additive through the water distribution mechanism. This ensures that the coating additive can fully enter the filter bag for filtration, avoiding waste, improving filtration efficiency, and enhancing the practicality of the device.

[0023] 2. In this invention, solid particles from the coating additives may remain inside the filter bag during filtration. Long-term accumulation can clog the filter bag and reduce filtration efficiency, requiring timely replacement. To replace the filter bag, pull the handle outwards on the pin to compress the spring of the limiting block. As the limiting block moves, the barrier plate automatically falls due to gravity, blocking the limiting block and preventing its movement, thus unlocking the locking mechanism. At this point, remove the filter bag and empty the solid particles inside, or replace it directly. To install the filter bag, pull up the barrier plate using the sliding plate, causing the limiting block to be pushed by the spring's rebound force, re-engaging the pin with the mounting bracket. This achieves quick filter bag replacement via the locking mechanism, facilitating filter bag cleaning and replacement, improving filtration efficiency, and enhancing the practicality of the device.

[0031] 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.

[0032] Reference Figure 1 - Figure 3 An embodiment of this utility model provides a coating additive extraction and filtration device, including a filter barrel 1, which serves to fix the internal structure. A top cover 2 is threadedly connected to the top of the filter barrel 1, which serves to seal the filter. Two mounting brackets 5 are slidably connected inside the filter barrel 1, which serves to connect filter bags 6. Filter bags 6 are fixedly connected to the bottom of both mounting brackets 5, which serve to filter materials. A water distribution mechanism is provided inside the filter barrel 1, which is used to evenly distribute coating additives into the filter bags 6. A locking mechanism is provided outside the filter barrel 1, which is used to quickly replace the filter bags 6.

[0033] The water distribution mechanism includes a drive motor 7, which provides power to drive the connecting shaft 8. The output end of the drive motor 7 is fixedly connected to the top of the top cover 2. The output end of the drive motor 7 is fixedly connected to the connecting shaft 8, which connects to a crank 9. The bottom of the connecting shaft 8 is fixedly connected to the crank 9, which connects to a U-shaped frame 10. The bottom of the crank 9 is rotatably connected to the U-shaped frame 10, which connects to a pipe sleeve 11. The inside of the U-shaped frame 10 is rotatably connected to the pipe sleeve 11, which is used to install a connecting pipe 12. The inside of the pipe sleeve 11 is fixedly connected to the connecting pipe 12. Several spray pipes 13 are fixedly connected to the bottom of the connecting pipe 12, and the spray pipes 13 distribute water. One end of the connecting pipe 12 is rotatably connected to the inside of the filter tank 1. The bottom of the filter tank 1 is fixedly connected to a receiving hopper 3, and a receiving bin 4 is provided at the bottom of the receiving hopper 3.

[0034] Specifically, when adding coating additives, the drive motor 7 is started to rotate the crank 9, which drives the sleeve 11 through the U-shaped frame 10, causing the connecting pipe 12 to drive the spray pipe 13 to swing back and forth inside the filter barrel 1, increasing the water distribution area.

[0035] Reference Figure 1 and Figure 4 - Figure 5The engaging mechanism includes four mounting shells 14, which serve to fix the internal structure. The opposite sides of the four mounting shells 14 are fixedly connected to the outside of the filter barrel 1. A spring 15 is fixedly connected inside the mounting shell 14. The spring 15 provides elastic force to push the limiting block 16. The limiting block 16 is fixedly connected to the side of the spring 15 closest to the filter barrel 1. The limiting block 16 prevents the spring 15 from falling off. A pin 17 is fixedly connected inside the limiting block 16. The pin 17 serves to engage and fix the filter barrel 1. The pin 17 passes through the outside of the filter barrel 1 and engages with the outside of the mounting frame 5. The top of the mounting shell 14 is fixedly connected to a fixing box 18, which serves to fix the internal structure. Inside the fixing box 18, a sliding plate 19 is slidably connected, which serves to connect to the baffle plate 20. The bottom of the sliding plate 19 is fixedly connected to the baffle plate 20, which serves to prevent the movement of the limiting block 16. The bottom of the baffle plate 20 abuts against the top of the limiting block 16. The limiting block 16 is slidably connected inside the mounting shell 14. A pin 17 passes through both ends of the mounting shell 14. A handle 21 is fixedly connected to the side of the pin 17 away from the limiting block 16.

[0036] To remove the filter bag 6, simply pull the pin 17 outward from the handle 21 to release it from the engagement with the mounting bracket 5.

[0037] Working principle: During filtration, the coating additive is conveyed through the connecting pipe 12 to the spray pipe 13 and sprayed into the filter bag 6 for filtration. After filtration, it falls into the collection bin through the collection hopper 3 for collection. During the material spreading process, the drive motor 7 is started to drive the connecting shaft 8, which drives the U-shaped frame 10 through the crank 9, causing the sleeve 11 to drive the connecting pipe 12 to swing back and forth inside the filter bin 1. The coating additive is evenly sprayed into the filter bag 6 through the spray pipe 13.

[0038] During the filtration process, solid particles from coating additives may remain inside the filter bag 6. Long-term accumulation can clog the filter bag 6, reducing filtration efficiency, necessitating timely replacement. To replace the filter bag 6, pull the pin 17 outwards using the handle 21, causing the limit block 16 to compress the spring 15. As the limit block 16 moves, the baffle plate 20 automatically falls due to gravity, blocking the limit block 16 and preventing its movement, thus unlocking the locking mechanism. At this point, remove the filter bag 6, empty the solid particles inside, or replace it directly. To install the filter bag 6, pull up the baffle plate 20 using the slide plate 19, causing the limit block 16 to be pushed by the spring 15, re-engaging the pin 17 with the mounting bracket 5.

[0039] 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.
