Description

Technical Field

[0001] This utility model relates to the field of paint filtration technology, and in particular to a solid particulate filter for paint processing. Background Technology

[0002] Solid particles in paint can cause a rough, uneven surface to the coating, affecting its appearance. Furthermore, these particles can also impact the coating's durability, shorten its lifespan, and increase the risk of cracking or peeling.

[0003] To ensure paint quality, the paint is typically filtered during production to remove solid particles completely. Since these particles are generally small in diameter, they gradually accumulate on the filter screen during filtration, causing blockages. This necessitates regular manual cleaning of the filter screen, affecting filtration efficiency. Utility Model Content

[0004] This utility model discloses a solid particulate filter for paint processing, aiming to solve the technical problem that, due to the generally small diameter of particles, particles gradually accumulate on the surface of the filter screen and cause blockage during filtration. This necessitates manual cleaning of the filter screen at regular intervals, affecting filtration efficiency.

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

[0006] A solid particulate filter for paint processing includes a tank, a flow guiding mechanism, a filtering mechanism and a liquid storage tank disposed in the tank, a suction mechanism disposed on one side of the tank, and a sealing door connected to the inner wall of one side of the tank via a hinge.

[0007] The filtration mechanism includes a base frame, a support shaft eccentrically fixed to the top of the base frame, a stepper motor fixedly connected to the top of the support shaft, filter bags distributed around the outer periphery of the base frame, a filter screen mounted on the base frame, a circular baffle fixedly connected to the outer wall of the top of the base frame, a conical support movably fitted to the outer wall of the top of the filter screen, and multiple through slots I through the conical support and a through slot III transversely through the bottom of the conical support;

[0008] The conical bracket is fixedly connected to the bottom end of the drainage mechanism. The outer periphery of the base frame is provided with a through groove two, and the filter bag is located at the bottom end of the through groove two.

[0009] The outer wall of the circular baffle is fixedly connected with multiple slides, and the inner wall of the tank is provided with a limiting groove, and the multiple slides are simultaneously moved and engaged in the limiting groove.

[0010] The inner wall of the top of the tank is inlaid with a bearing, and the support shaft is connected to the bearing. The stepper motor is installed at the top of the tank.

[0011] By incorporating a filtration mechanism, a stepper motor drives the base frame and circular baffle to rotate eccentrically via a support shaft. This assists in the falling of paint, optimizing filtration efficiency. Simultaneously, the contact position between the filter screen surface and the bottom of the conical support changes with rotation, continuously cleaning the filter screen surface during filtration. Furthermore, the rotation pushes accumulated particles outwards into the filter bag, thereby continuously reducing the amount of particles accumulated on the filter screen and ensuring its continuous filtration effect.

[0012] In a preferred embodiment, the drainage mechanism includes a transition chamber, a first inclined guide plate and a second inclined guide plate that are obliquely fixed to the inner wall of the transition chamber, and a square through slot that is disposed through the second inclined guide plate.

[0013] The top inner wall of the tank is fixedly connected to a feed inlet, and the transition chamber is fixedly connected to the top inner wall of the tank and located at the bottom of the feed inlet. The first inclined guide plate and the second inclined guide plate are arranged in an alternating manner.

[0014] The surface of the inclined guide plate is provided with multiple protrusions, and a through hole is provided through the inclined guide plate, through which the support shaft passes;

[0015] The outer wall of the inclined guide plate is fixedly connected with a baffle, and the baffle surrounds the square through groove. The bottom end of the transition chamber is fixedly connected with a cross frame, and the conical bracket is fixedly connected to the bottom end of the cross frame.

[0016] With the addition of a flow-guiding mechanism, the paint can fall along the surfaces of inclined guide plates one and two onto the surface of the filter screen. During this process, the setting of multiple protrusions enables preliminary filtration, while the setting of square through grooves and baffles can divide the paint into two streams as it flows, thereby achieving uniform distribution of the paint on the filter screen and optimizing the filtration effect.

[0017] In a preferred embodiment, the suction mechanism includes a suction machine, a vent pipe connected to the input end of the suction machine, a corrugated hose connected to the output end of the suction machine, and a valve installed on the vent pipe.

[0018] A mounting bracket is fixedly connected to one side of the outer wall of the tank, and the suction machine is mounted on the mounting bracket. One end of the corrugated hose extends outdoors, and one end of the vent pipe is connected to one side of the inner wall of the tank.

[0019] By incorporating a suction mechanism, the concentration of odors inside the tank can be reduced, preventing odor interference during the disassembly of the storage tank and optimizing the working environment. Furthermore, the valve design allows for sealing without starting the suction machine, ensuring a relatively sealed space during the filtration process.

[0020] As described above, a solid particulate filter for paint processing includes a tank, a flow guiding mechanism, a filtering mechanism, and a liquid storage cylinder disposed within the tank, a suction mechanism disposed on one side of the tank, and a sealing door connected to the inner wall of one side of the tank via a hinge. The filtering mechanism includes a base frame, a support shaft eccentrically fixed to the top of the base frame, a stepper motor fixedly connected to the top of the support shaft, filter bags distributed around the outer periphery of the base frame, a filter screen mounted on the base frame, a circular baffle fixedly connected to the outer wall of the top of the base frame, a conical support movably fitted to the outer wall of the top of the filter screen, and multiple through slots (first type) penetrating the conical support and a through slot (third type) transversely penetrating the bottom of the conical support. The solid particulate filter for paint processing provided by this utility model can continuously reduce the accumulation of particles on the filter screen, ensuring the continuous filtering effect of the filter screen.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] The solid particulate filter disclosed in this utility model is mainly used in paint filtration scenarios.

[0028] Reference Figures 1-3 A solid particulate filter for paint processing includes a tank 3, a flow guiding mechanism 2 disposed in the tank 3, a filtering mechanism 5 and a liquid storage cylinder 6, a suction mechanism 1 disposed on one side of the tank 3, and a sealing door 4 connected to the inner wall of one side of the tank 3 by a hinge.

[0029] The filtration mechanism 5 includes a base frame 510, a support shaft 503 eccentrically fixed to the top of the base frame 510, a stepper motor 501 fixedly connected to the top of the support shaft 503, filter bags 512 distributed around the outer periphery of the base frame 510, filter screens 511 mounted on the base frame 510, a circular baffle 506 fixedly connected to the outer wall of the top of the base frame 510, a conical support 504 movably fitted to the outer wall of the top of the filter screen 511, multiple through slots 505 penetrating the conical support 504, and a through slot 513 transversely penetrating the bottom of the conical support 504. In the filtration mechanism 5, the stepper motor 501 drives the base frame 510 and the circular baffle 506 eccentrically via the support shaft 503. The rotation causes the circular baffle 506 to rotate and adhere to the inner wall of the tank 3. This rotation assists in the falling of the paint, optimizing filtration efficiency. Simultaneously, the contact position between the surface of the filter screen 511 and the bottom of the conical support 504 changes with the rotation, allowing for continuous cleaning of the surface of the filter screen 511 during filtration. This prevents excessive accumulation of particles in one location. Furthermore, the rotation pushes the accumulated particles gradually outward into the filter bag 512. The groove 513 allows particles inside the conical support 504 to be transferred outward, thereby continuously reducing the amount of particles accumulated on the filter screen 511 and ensuring the continuous filtration effect of the filter screen 511.

[0030] Reference Figure 2 and Figure 3 In a preferred embodiment, the conical support 504 is fixedly connected to the bottom end of the drainage mechanism 2, and the outer periphery of the base frame 510 is provided with a through groove 509, and the filter bag 512 is located at the bottom end of the through groove 509.

[0031] Reference Figure 2 In a preferred embodiment, a plurality of slides 507 are fixedly connected to the outer wall of the circular baffle 506, and a limiting groove 508 is provided around the inner wall of the tank body 3, and the plurality of slides 507 are simultaneously engaged in the limiting groove 508.

[0032] Reference Figure 2 In a preferred embodiment, a bearing 502 is embedded in the inner wall of the top of the tank body 3, and a support shaft 503 is connected to the bearing 502. A stepper motor 501 is installed at the top of the tank body 3.

[0033] Reference Figure 4 In a preferred embodiment, the drainage mechanism 2 includes a transition chamber 202, a first inclined guide plate 204 and a second inclined guide plate 207 that are obliquely fixed to the inner wall of the transition chamber 202, and a square through slot 208 that is disposed through the second inclined guide plate 207.

[0034] Reference Figure 4 In a preferred embodiment, a feed inlet 201 is fixedly connected to the inner wall of the top of the tank body 3, and a transition chamber 202 is fixedly connected to the inner wall of the top of the tank body 3 and located at the bottom of the feed inlet 201. Inclined guide plate 1 204 and inclined guide plate 207 are arranged alternately.

[0035] Reference Figure 4 In a preferred embodiment, the surface of the inclined guide plate 204 is provided with a plurality of protrusions 203, and a through hole 205 is provided through the inclined guide plate 204, through which the support shaft 503 passes.

[0036] Reference Figure 4 In a preferred embodiment, a baffle 209 is fixedly connected to the outer wall of the second inclined guide plate 207, and the baffle 209 surrounds the square through groove 208. A cross frame 206 is fixedly connected to the bottom end of the transition chamber 202, and a conical bracket 504 is fixedly connected to the bottom end of the cross frame 206. When the paint enters the transition chamber 202 through the inlet 201, it will fall down along the surfaces of the first inclined guide plate 204 and the second inclined guide plate 207 to the surface of the filter screen 511. During the process, the setting of multiple protrusions 203 can block some of the particles in the paint to achieve preliminary filtration. The setting of the square through groove 208 and the baffle 209 can divide the paint into two streams when it flows, one stream falls from the second inclined guide plate 207 and the other stream falls from the square through groove 208, thereby achieving uniform distribution of the paint on the filter screen 511 and optimizing the filtration effect.

[0037] Reference Figure 2 In a preferred embodiment, the suction mechanism 1 includes a suction machine 102, a vent pipe 104 connected to the input end of the suction machine 102, a corrugated hose 101 connected to the output end of the suction machine 102, and a valve 105 installed on the vent pipe 104.

[0038] Reference Figure 2In a preferred embodiment, a mounting bracket 103 is fixedly connected to one outer wall of the tank 3, and a suction machine 102 is mounted on the mounting bracket 103. One end of the corrugated hose 101 extends outside the room, and one end of the vent pipe 104 is connected to one inner wall of the tank 3. When the sealing door 4 is opened and the liquid storage cylinder 6 is taken out, the suction machine 102 and the valve 105 can be turned on in advance to extract the odor gas in the tank 3 through the vent pipe 104 and the corrugated hose 101, thereby reducing the odor concentration in the tank 3, avoiding the influence of odor when disassembling the liquid storage cylinder 6, optimizing the working environment, and through the setting of the valve 105, it can be closed without starting the suction machine 102 to ensure a relatively sealed space during the filtration process.

[0039] Working principle: In the filter mechanism 5, the stepper motor 501 drives the base frame 510 and the circular baffle 506 to rotate eccentrically via the support shaft 503. This causes the circular baffle 506 to rotate against the inner wall of the tank 3. The rotation helps the paint to fall and optimizes the filtration efficiency. At the same time, the contact position between the surface of the filter screen 511 and the bottom of the conical support 504 changes with the rotation. This allows for continuous cleaning of the surface of the filter screen 511 during the filtration process, preventing excessive accumulation of particles in one position. With the rotation, the accumulated particles can be pushed to gradually move outward into the filter bag 512. The groove 513 allows the particles inside the conical support 504 to be pushed to the outside of the conical support 504, thereby continuously reducing the amount of particles accumulated on the filter screen 511 and ensuring the continuous filtration effect of the filter screen 511.

[0040] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
