Abstract
Description
Technical Field
[0001] This application relates to the field of coating filtration technology, and in particular to an anti-clogging device for a coating filter machine. Background Technology
[0002] Paint is a type of material that is applied to the surface of an object and forms a thin film under certain conditions to provide protection and decoration. If the raw materials of the paint contain large particulate impurities, it will affect the uniformity of the mixture and thus affect the coating effect. Therefore, paint filtration is an important step.
[0003] In existing paint filtration devices, when filtering paint for a long time, a lot of impurities tend to accumulate on the surface of the filter screen, causing the mesh to become clogged. At the same time, since the screen is usually fixed inside the filter box, it is not convenient for staff to clean the filter screen. In addition, during the filtration process, paint powder tends to adhere to the inner wall of the filter box, resulting in material waste. Utility Model Content
[0004] To address the problems of existing paint filtration devices, where impurities tend to accumulate on the surface of the filter screen during prolonged filtration, causing mesh blockage, and the fact that the filter screen is typically fixed inside the filter box, making it inconvenient for workers to clean it, and the paint powder tends to adhere to the inner wall of the filter box during filtration, resulting in material waste, this application provides an anti-clogging device for a paint filter machine.
[0005] The anti-clogging device for a paint filter machine provided in this application adopts the following technical solution:
[0006] A clogging prevention device for a paint filter includes a filter housing. Support legs are symmetrically fixed at the bottom of the filter housing, and a sealing cover is detachably fixed at the top. A funnel is installed through one side of the sealing cover, and a U-shaped seat is fixedly installed in the middle. A motor is fixedly installed on the top of the U-shaped seat, and a rotating shaft is fixedly installed at the output end of the motor. One end of the rotating shaft passes through the sealing cover and extends into the filter housing, where a spiral blade is installed. A cylindrical body is fixedly installed on the side of the sealing cover away from the U-shaped seat, and the rotating shaft is installed inside the cylindrical body. Several through holes are opened on the outer surface of the cylindrical body. A filter screen is installed inside the filter housing below the rotating shaft, and a discharge port is opened at the bottom.
[0007] Preferably, a fixing plate is provided on the outside of the filter box, and the sealing box cover is fixed to the fixing plate by bolts.
[0008] Preferably, the filter screen has a conical structure.
[0009] Preferably, scraper rods are symmetrically arranged at the bottom end of the rotating shaft, and a scraper plate is fixedly arranged above the end of the scraper rod away from the rotating shaft, which contacts the side wall of the filter box. Bristles that contact the middle of the filter screen are installed below the scraper plate.
[0010] Preferably, a valve is installed at the bottom of the discharge port.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] This anti-clogging device for the paint filter works by rotating the outer spiral blades during filtration. This causes the paint on the filter screen to churn, allowing paint and impurities to enter the cylinder. This accelerates the flow of the paint, carrying away accumulated impurities. The impurities are then ejected through the through-holes in the cylinder for the next cycle. This ensures that the liquid above the filter screen is always in a state of circulation, reducing the accumulation of impurities on the filter screen and thus minimizing clogging, improving ease of use.

[0017] 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.
[0018] Please see Figures 1 to 3 This utility model provides a technical solution:
[0019] A coating filter anti-clogging device includes a filter box 1. Support legs 2 are symmetrically fixed at the bottom of the filter box 1, and a sealing cover 3 is detachably fixed at the top. A funnel 6 is installed through one side of the sealing cover 3, and a U-shaped seat 4 is fixedly installed in the middle. A motor 7 is fixedly installed at the top of the U-shaped seat 4. A rotating shaft 5 is fixedly installed at the output end of the motor 7. One end of the rotating shaft 5 passes through the sealing cover 3 and extends into the filter box 1, where a spiral blade 8 is installed. A cylinder 9 is fixedly installed on the side of the sealing cover 3 away from the U-shaped seat 4. The rotating shaft 5 is installed inside the cylinder 9. Several through holes 10 are opened on the outer surface of the cylinder 9. A filter screen 11 is installed inside the filter box 1 and below the rotating shaft 5, and a discharge port 12 is opened at the bottom.
[0020] In use, paint can be added into the filter box 1 through the funnel 6. The paint is filtered through the filter screen 11, and impurities accumulate on top of the filter screen 11. At this time, the drive motor 7 drives the rotating shaft 5 to rotate. The spiral blades on the outside can cause the paint on the filter screen 11 to tumble, allowing the paint and impurities to enter the cylinder 9. The accumulated impurities are carried along with the paint, thereby accelerating the flow of the paint. Finally, it is sprayed out through the through hole 10 on the cylinder 9 to continue the next cycle. In this way, the liquid above the filter screen 11 is always in a state of circulation, thereby reducing the accumulation of a large amount of impurities on the filter screen 11, thus reducing clogging and improving the ease of use.
[0021] A fixing plate 13 is provided on the outside of the filter box 1. The sealing box cover 3 is fixed to the fixing plate 13 by bolts, which facilitates installation and disassembly and makes subsequent cleaning easier.
[0022] The filter screen 11 has a conical structure.
[0023] A scraper 14 is symmetrically arranged at the bottom end of the rotating shaft 5. A scraper 15 that contacts the side wall of the filter box 1 is fixedly arranged above the end of the scraper 14 away from the rotating shaft 5. A brush bristle 16 that contacts the middle of the filter screen 11 is installed below the scraper 14.
[0024] When the rotating shaft 5 rotates, it drives the scraper 14 and scraper 15 to rotate synchronously. The bristles 16 below the scraper 14 can further agitate the impurities remaining on the filter screen 11, so that the impurities can be carried into the cylinder 9 by the spiral blades 8 to complete the circulation flow, thereby further reducing the accumulation of impurities on the filter screen 11 and reducing the possibility of clogging. Meanwhile, the scraper 15 will scrape the inner wall of the filter box 1 to avoid a large amount of paint adhering to the inner wall and causing waste.
[0025] A valve is installed at the bottom of the discharge port 12 to control the entry and exit of the coating.
[0026] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
