Description

Technical Field

[0001] This utility model relates to the field of filtration technology, specifically a filtration device for processing coating materials. Background Technology

[0002] Coating materials are applied to the surface of objects to be protected or decorated, forming a continuous film that adheres firmly to the object. They are usually viscous liquids made primarily of resin, oil, or emulsion, with or without pigments and fillers, and with appropriate additives, and formulated with organic solvents or water. Generally, the produced coating materials contain a small amount of insoluble impurities. Therefore, filtration through a filtration device can further improve the performance of the coating materials.

[0003] In the patent application with authorization publication number CN209392826U, authorization publication date of 2019-09-17, entitled "A Filtering Device for Coating Material Processing", the coating material to be filtered is transported from the nozzle to the inside of the cylinder, so that the coating material is evenly distributed in the cylinder. The motor drives the blade to rotate, so that the coating material inside the cylinder is in a flowing state, which increases the filtration speed. The waste chamber is moved upward by the pull rod to remove the residual coating material, thus completing the cleaning and recycling of the residual coating material. Furthermore, water is injected through the clean water pipe to remove the filter residue in the filter screen, thus completing the cleaning of the filter screen.

[0004] In actual use of the above-mentioned device, during the filtration process, particulate impurities easily clog the filter screen. As the usage time increases, the filtration capacity of the filter screen will gradually decrease, requiring frequent shutdowns of the equipment to clean or replace the filter screen. Furthermore, due to the lack of effective heating and temperature control methods, when the ambient temperature is low or the coating material itself needs to be filtered under specific temperature conditions, the performance of the coating material will change due to temperature factors, such as reduced fluidity, which in turn affects the overall processing performance of the coating material and the quality of the final product.

[0005] Therefore, we propose a filtration device for coating material processing to solve the problems mentioned above. Utility Model Content

[0006] 1. The technical problem to be solved by the utility model:

[0007] The purpose of this invention is to provide a filtration device for coating material processing to solve the problems currently existing in the market as described in the background art.

[0008] 2. Technical Solution:

[0009] To achieve the above objectives, the present invention provides the following technical solution: a filter device for processing coating materials, comprising a housing, an air supply component installed on the left outer wall of the housing, and a heating component installed at the output end of the air supply component, a guide plate fixed inside the lower left side of the housing, an auger conveyor installed inside the lower right side of the housing, and a discharge pipe connected to the rear right side of the housing.

[0010] The upper end of the housing is detachably fitted with a top cover, and the lower end of the top cover is fixed with a column rod. A filter element is elastically and telescopically installed at the lower end of the column rod. A threaded rod is installed in the bearing inside the housing, and a guide rod is fixed inside the housing. An air outlet assembly is installed between the threaded rod and the guide rod. The air inlet pipe of the air outlet assembly is connected to the air outlet of the air supply assembly.

[0011] Furthermore, the guide plate is designed with a left-high and right-low shape.

[0012] The above technical solution allows the filtered coating material to fall from the guide plate to the auger conveyor, and then be discharged from the discharge pipe using the auger conveyor.

[0013] Furthermore, the filter element includes a frame that is elastically slidably mounted on the outside of the column, a filter screen is installed inside the frame, and protrusions are fixed at equal intervals on the lower ends of the left and right sides of the frame.

[0014] The above technical solution allows the filter element to slide up and down on the column when it is subjected to force.

[0015] Furthermore, the air outlet assembly includes two brackets, one of which is threaded onto the outside of the threaded rod, and the other is slidably sleeved onto the outside of the guide rod. A support frame is placed above the brackets, and an air outlet pipe is installed between the two support frames.

[0016] The above technical solution enables airflow to be ejected from the outlet pipe when the air supply component is activated.

[0017] Furthermore, a fixing component is installed on the bracket for fixing the support frame. The fixing component includes a screw rotatably mounted on the bracket, and a positioning block is threaded on the outer side of the screw. The side of the positioning block is attached to a limiting plate, and the limiting plate is fixed on the bracket. At the same time, the positioning block and the support frame form a concave-convex fit.

[0018] The above technical solution enables the positioning block to move and extend into the support frame after the screw rotates, thus fixing the support frame.

[0019] Furthermore, the uppermost position of the support frame is higher than the lowest position of the protrusion, and both the upper end of the support frame and the lower end of the protrusion are designed with an arc shape.

[0020] The above technical solution allows the support frame to press against the protrusion when it moves back and forth, thus driving the filter element to move upward.

[0021] 3. Beneficial effects:

[0022] Compared with the prior art, the technical solution provided by this utility model is a filtration device for coating material processing. By blowing air through the air outlet component, it prevents particles from clogging the filter mesh, ensuring continuous and effective filtration. Simultaneously, it prevents performance changes in coating materials due to excessively low temperatures. The specific details are as follows:

[0023] After the coating material is put into the box, the motor at the end of the threaded rod is started, which drives the threaded rod to rotate. After the threaded rod rotates, the air outlet component can be displaced under the limiting action of the guide rod. When the air supply component is started, it can make the outside air enter the air outlet through the air inlet pipe. Then the air outlet sprays air onto the filter screen through its own air outlet to prevent particles from clogging the filter screen mesh and ensure the continuous and effective filtration of the filter screen. At the same time, the airflow is heated by the heating component to give the airflow a certain temperature, which helps to prevent the coating material from changing its performance due to excessively low temperature.

[0024] When the threaded rod rotates forward and backward, it drives the air outlet assembly to move back and forth, which in turn drives the support frame to move back and forth synchronously. During the movement, the support frame squeezes the protrusion, which in turn drives the frame to move upward. Then, under the action of gravity and elasticity, it moves downward in the opposite direction, thereby achieving vibration and further improving the filtration capacity of the filter screen.

[0035] Please see Figure 1-5A filtration device for coating material processing includes a housing 1, an air supply component 2 installed on the left outer wall of the housing 1, a heating component 3 installed at the output end of the air supply component 2, a guide plate 4 fixed inside the lower left side of the housing 1, an auger conveyor 5 installed inside the lower right side of the housing 1, and a discharge pipe 6 connected to the rear right side of the housing 1; the guide plate 4 is designed with the left side higher than the right side.

[0036] After being filtered, the coating material falls onto the guide plate 4, then concentrates at the auger conveyor 5, is transported by the auger conveyor 5, and is then discharged from the discharge pipe 6.

[0037] The upper end of the housing 1 is detachably fitted with a top cover 7, and the lower end of the top cover 7 is fixed with a column rod 71. The lower end of the column rod 71 is elastically telescopically fitted with a filter element 8. The internal bearing of the housing 1 is fitted with a threaded rod 9, and the internal part of the housing 1 is fixed with a guide rod 10. An air outlet assembly 11 is installed between the threaded rod 9 and the guide rod 10. The air inlet pipe of the air outlet assembly 11 is connected to the air outlet of the air supply assembly 2. The filter element 8 includes a frame 81 elastically slidably installed on the outside of the column rod 71. A filter screen 82 is installed inside the frame 81, and protrusions 83 are fixed at equal intervals on the lower ends of the left and right sides of the frame 81. The air outlet assembly 11 includes two brackets 111. One bracket 111 is threadedly fitted on the outside of the threaded rod 9, and the other bracket 111 is slidably fitted on the outside of the guide rod 10. A support frame 113 is placed above the bracket 111, and an air outlet pipe 114 is installed between the two support frames 113.

[0038] The coating material is put into the box 1, and the motor at the end of the threaded rod 9 is started to drive the threaded rod 9 to rotate. After the threaded rod 9 rotates, under the limiting action of the guide rod 10, the air outlet assembly 11 is displaced and the air supply assembly 2 is started. Outside air can enter the air outlet pipe 114 through the air inlet pipe. Then the air outlet pipe 114 sprays air onto the filter screen 82 through its own air outlet to prevent particles from clogging the mesh of the filter screen 82 and to ensure the continuous and effective filtration of the filter screen 82. At the same time, the airflow is heated by the heating assembly 3 so that the sprayed airflow has a certain temperature, which helps to prevent the coating material from changing its performance due to excessively low temperature.

[0039] A fastener 112 is installed on the bracket 111. The fastener 112 is used to fix the support frame 113. The fastener 112 includes a screw 1121 rotatably installed on the bracket 111. A positioning block 1122 is threaded on the outer side of the screw 1121. The side of the positioning block 1122 is attached to a limiting plate 1123. The limiting plate 1123 is fixed on the bracket 111. At the same time, the positioning block 1122 and the support frame 113 form a concave-convex fit.

[0040] Rotate screw 1121 to drive positioning block 1122 to disengage from support frame 113. Then, support frame 113 and air outlet pipe 114 can be removed from two brackets 111 and the air outlet pipe 114 can be cleaned.

[0041] The uppermost position of the support frame 113 is higher than the lowest position of the protrusion 83, and both the upper end of the support frame 113 and the lower end of the protrusion 83 are designed with arc-shaped structures.

[0042] When the threaded rod 9 rotates forward and backward, driving the air outlet assembly 11 to move back and forth, the support frame 113 will move back and forth synchronously. During the movement, the support frame 113 squeezes the protrusion 83, thereby driving the frame 81 to move upward. Then, under the action of gravity and elasticity, it moves downward in the opposite direction, thereby achieving shaking and further improving the filtration capacity of the filter screen 82.

[0043] Working principle: When using this filter device for coating material processing, such as Figure 1-5 As shown, the coating material is put into the box 1, the motor at the end of the threaded rod 9 is started, and the air outlet assembly 11 is moved by the cooperation of the threaded rod 9 and the guide rod 10. The air supply assembly 2 is started, so that the outside air enters the air outlet pipe 114 through the air inlet pipe. Then the air outlet pipe 114 sprays air onto the filter screen 82 through its own air outlet to prevent particles from clogging the mesh of the filter screen 82 and to ensure the continuous and effective filtration of the filter screen 82. At the same time, the airflow is heated by the heating assembly 3 to give the airflow a certain temperature, which helps to prevent the coating material from changing its performance due to low temperature. The filtered coating material falls on the guide plate 4 and is then discharged from the discharge pipe 6 through the auger conveyor 5.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
