Description

Technical Field

[0001] This utility model relates to the field of paint raw material production technology, and in particular to a paint raw material impurity filtration device. Background Technology

[0002] Paint is a type of coating. It refers to a general term for liquid or solid materials that can be applied to the surface of an object to form a solid film with protective, decorative, or special properties (anti-corrosion, insulation, etc.). During the production of paint, impurities or foreign objects may be mixed in at various stages, affecting the quality of the paint. For example, grinding media may be mixed in when dispersing with sand mill. Therefore, the filtration process is one of the most important steps in the paint production process.

[0003] When existing paint raw materials are filtered, due to the viscosity of the paint, the paint raw materials tend to accumulate inside the filtration equipment during the filtration process. The efficiency of the paint raw materials falling through the filter plate or filter screen is relatively low, which reduces the smoothness of the paint raw material filtration and thus seriously affects the filtration efficiency. Therefore, a paint raw material impurity filtration device is proposed to solve the above problems. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] like Figure 1-5 As shown, the present invention proposes a paint raw material impurity filtration device, which includes a housing 1, and a filtration structure 2 is provided inside the housing 1.

[0026] In this invention, the filter structure 2 allows the paint raw material to be fully agitated during filtration, enabling it to flow and thus allowing for faster filtration, improving the smoothness of the filtration process and further enhancing the filtration efficiency.

[0027] In an optional embodiment, the filter structure 2 includes a fixed box 21, a rotating rod 22, a drive assembly 23, a U-shaped frame 24, a filter frame 25, a support assembly 26, a guide plate 27, and a discharge port 28. The fixed box 21 is located on the back of the box body 1. The rotating rod 22 is rotatably connected to the rear side wall of the inner cavity of the fixed box 21 and extends into the interior of the box body 1. The drive assembly 23 is located inside the fixed box 21, and the output end of the drive assembly 23 is connected to the rotating rod 22. The U-shaped frame 24 is located at the front end of the rotating rod 22. The filter frame 25 is located inside the U-shaped frame 24. The support assembly 26 is located inside the U-shaped frame 24, and the U-shaped frame 24 is connected to the filter frame 25 through the support assembly 26. The guide plate 27 is located inside the box body 1, and the left side of the guide plate 27 is inclined downward. The discharge port 28 is opened on the left side of the box body 1 and extends into its interior, and the discharge port 28 corresponds to the left side of the guide plate 27.

[0028] It should be noted that the filter frame 25 can hold the paint raw materials, and the drive component 23 can drive the rotating rod 22 to rotate clockwise and counterclockwise alternately. During the alternating rotation of the rotating rod 22, the rotating rod 22 will drive the U-shaped frame 24 to rotate alternately, so that the U-shaped frame 24 can drive the filter frame 25 to shake, so that the paint raw materials inside the filter frame 25 can shake, thereby making the paint raw materials flow inside the filter frame 25, improving the smoothness and efficiency of paint filtration.

[0029] In addition, the filter frame 25 can be installed inside the U-shaped frame 24 by the support component 26, so that the U-shaped frame 24 can drive the filter frame 25 to shake. After filtration is completed, the filter frame 25 can be removed from the U-shaped frame 24 by the support component 26, which makes it convenient to clean the filter frame 25.

[0030] It should be noted that during the filtration process, the filtered paint material will fall to the top of the guide plate 27, and the tilt of the guide plate 27 will cause the filtered paint material to flow to the outlet 28. The outlet 28 can be connected to a discharge pipe or a container can be placed directly at the outlet 28 for easy collection of the filtered paint material.

[0031] In addition, the filter frame 25 consists of a square frame and a filter section. The filter section is installed at the bottom of the square frame and can be a filter bag or a concave filter plate. During the shaking of the filter frame 25, the paint material will flow inside the filter section, improving the filtration efficiency of the paint material. However, during shaking, the shaking amplitude of the filter frame 25 and the amount of paint inside the filter frame 25 should be controlled to prevent the paint material from leaking through the top of the filter frame 25 during shaking.

[0032] In an optional embodiment, the drive assembly 23 includes a servo geared motor 231, a fixed screw 232, a threaded block 233, a limit module 234, a rack 235, and a sector gear 236. The servo geared motor 231 is located on the right side of the fixed housing 21. The fixed screw 232 is mounted on the output shaft of the servo geared motor 231 via a coupling. The other end of the fixed screw 232 extends into the interior of the fixed housing 21. The threaded block 233 is threaded to the outside of the fixed screw 232. The limit module 234 is located at the bottom of the threaded block 233. The rack 235 is located at the top of the threaded block 233. The sector gear 236 is located on the outside of the rotating rod 22, and the rack 235 meshes with the sector gear 236.

[0033] It should be noted that when the servo geared motor 231 is started, the output shaft of the servo geared motor 231 will drive the fixed screw 232 to rotate. Under the action of the limit module 234, the threaded block 233 will not rotate. When the fixed screw 232 rotates, under the action of the thread thrust, the fixed screw 232 will drive the threaded block 233 to move to the left or right. The threaded block 233 will drive the rack 235 to move to the left or right. The rack 235 will drive the sector gear 236 meshing with it to rotate clockwise or counterclockwise. The sector gear 236 will drive the rotating rod 22 to rotate clockwise or counterclockwise.

[0034] By alternately starting the servo reduction motor 231 in both directions, the rack 235 can move back and forth, thereby causing the rotating rod 22 to rotate alternately in clockwise and counterclockwise directions.

[0035] In an optional embodiment, the limiting module 234 includes a limiting block and a limiting groove. The limiting block is located at the bottom of the threaded block 233, and the limiting groove is opened in the inner bottom wall of the fixed box 21. The limiting block is slidably connected to the inside of the limiting groove.

[0036] It should be noted that the threaded block 233 can be limited by the limiting block and the limiting groove. This not only prevents the threaded block 233 from rotating, but also limits the range of motion of the threaded block 233. This prevents the threaded block 233 from moving too much and causing it to disengage from the sector gear 236. At the same time, it also prevents the filter frame 25 from shaking too much and causing paint material to spill.

[0037] In an optional embodiment, the support assembly 26 includes two support grooves 261, two support blocks 262, and a fixing module 263. The two support grooves 261 are respectively opened on the left and right side walls of the inner cavity of the U-shaped frame 24, and the front of the two support grooves 261 are connected to the outside. The two support blocks 262 are respectively disposed on the left and right sides of the filter frame 25, and the two support blocks 262 are slidably connected to the inside of the two support grooves 261. The fixing module 263 is disposed on the top of the U-shaped frame 24.

[0038] It should be noted that the filter frame 25 can be installed in the inner cylinder of the U-shaped frame 24 through the two support slots 261 and the two support blocks 262, and the U-shaped frame 24 is also supported. After the filter frame 25 is installed, the two support blocks 262 can be fixed by the fixing module 263 to ensure the stability of the filter frame 25 after installation.

[0039] In an optional embodiment, the fixing module 263 includes two threaded grooves 2631, two movable screws 2632, and two knobs 2633. The two threaded grooves 2631 are respectively opened on the top of the two support blocks 262. The two movable screws 2632 are both located on the top of the U-shaped frame 24 and extend into the interior of the two threaded grooves 2631 respectively. The two movable screws 2632 are threadedly connected to the two threaded grooves 2631 respectively. The two knobs 2633 are respectively located on the top of the two movable screws 2632.

[0040] It should be noted that when the filter frame 25 needs to be disassembled after filtration is completed, the two knobs 2633 need to be turned first. The two knobs 2633 will drive the two movable screws 2632 to rotate respectively. When the two movable screws 2632 rotate, they will move upward or downward under the action of the thread thrust. When the two movable screws 2632 move upward and disengage from the two threaded grooves 2631 respectively, the filter frame 25 can be pulled forward, so that the two support blocks 262 slide out from the two support grooves 261 respectively, thereby removing the filter frame 25.

[0041] In addition, when installing the filter frame 25, the two support blocks 262 need to be slidably connected to the inside of the two support grooves 261 respectively, and the filter frame 25 needs to be pushed backward until it can not be pushed any further. At this time, turn the knob 2633 to make the movable screw 2632 move downward. When the two movable screws 2632 are threadedly connected to the two threaded grooves 2631 respectively, the support block 262 can be fixed by the movable screws 2632 and the threaded grooves 2631, thereby ensuring the stability of the filter frame 25 after installation.

[0042] In an optional embodiment, the front of the box body 1 is hinged to a door 3, the front of the door 3 is provided with an observation window 4, the front of the door 3 is provided with a handle 5, the bottom four corners of the box body 1 are provided with support columns 6, the top of the box body 1 is connected to a feed pipe 7, and the feed pipe 7 is located above the filter frame 25.

[0043] It should be noted that opening the door 3 allows for easy disassembly or installation of the filter frame 25, while closing the door 3 can cover the front of the chamber 1. The handle 5 facilitates the opening and closing of the door 3, and the observation window 4 allows for observation of the filtration process inside the chamber 1. This helps prevent excessive paint material inside the filter frame 25 or excessive shaking of the filter frame 25, which could cause paint material to spill during filtration.

[0044] In addition, the box 1 can be supported by four support columns 6, and the paint raw material can be sent into the filter frame 25 through the feed pipe 7. An electric valve can be installed inside the feed pipe 7, and the amount of paint raw material added to the filter frame 25 can be controlled by controlling the electric valve.

[0045] It should be noted that a controller is installed on the outside of the housing 1. The servo geared motor 231 and the electric valve are electrically connected to the controller. The servo geared motor 231 and the electric valve can be controlled through the controller.

[0046] Working principle:

[0047] In operation, the paint material impurity filtration device first feeds the paint material into the filter frame 25 through the feed pipe 7. Then, the servo reduction motor 231 is started, causing the U-shaped frame 24 to rotate clockwise and counterclockwise. Under the action of the support component 26, the U-shaped frame 24 drives the filter frame 25 to shake, thereby causing the paint material inside the filter frame 25 to shake and flow, improving the smoothness and efficiency of paint filtration. The filtered paint material falls directly onto the guide plate 27, and the tilt of the guide plate 27 allows the filtered paint material to flow to the outlet 28 for easy collection. After filtration, the housing 1 is opened, and the two knobs 2633 are turned. When the two movable screws 2632 move upward and disengage from the two threaded grooves 2631, the filter frame 25 can be disassembled for cleaning.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
