Abstract
Description
Technical Field
[0001] This utility model relates to the field of coating processing technology, and in particular to an anti-caking mixing device for coating processing. Background Technology
[0002] With the increasing demands for coating quality from industries such as construction, automotive, and furniture, the mixing process in coating production has become particularly important. During coating processing, the uniform mixing of raw materials directly affects the quality and performance of the finished product. Problems such as raw material agglomeration and uneven dispersion have always been technical challenges in production. Traditional mixing equipment often struggles to effectively solve problems like powder agglomeration and stratification, leading to defects in the coating such as particle size and uneven gloss.
[0003] Currently, most mixing devices used in coating processing employ a single-layer stirring structure, relying on the rotation of impellers or helical blades to mix materials. For example, some devices use anchor mixers in conjunction with helical blades to break up clumps through mechanical shearing force; others enhance the turbulence effect of the fluid by setting static guide plates. However, these mixing devices have problems in practical applications. For instance, a single-layer stirring structure cannot simultaneously meet the needs of clump breaking and full-area mixing, especially for coating systems with high solids content or easy settling. The material in the central area is prone to forming a "dead zone" due to poor flowability, resulting in insufficient material exchange between the upper and lower layers. Therefore, an anti-clumping mixing device for coating processing is proposed to solve the above problems. Utility Model Content
[0004] To overcome the above deficiencies, this utility model provides an anti-caking mixing device for coating processing, which aims to improve the situation where a single-layer stirring structure cannot simultaneously meet the needs of agglomeration and crushing and full-area mixing. In particular, for coating systems with high solids content or easy sedimentation, the material in the central area is prone to forming a "dead zone" due to poor flowability, resulting in insufficient material exchange between the upper and lower layers.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a coating processing anti-caking mixing device, comprising a tank, a support frame fixedly connected to the outer wall of the tank, a feed inlet fixedly connected to the inside of the tank, a tank cover slidably connected to the upper surface of the tank, a motor fixedly connected inside the tank cover, and a stirring assembly provided at the output end of the motor;
[0006] The stirring assembly includes a second connecting rod, a first connecting rod, and a first stirring roller. One end of the second connecting rod is fixedly connected to the output end of the motor, and one end of the first connecting rod is fixedly connected to the other end of the second connecting rod. The inner wall of the first stirring roller is fixedly connected to the outer wall of the second connecting rod. A first support rod is fixedly connected inside the first connecting rod, and the second stirring roller is fixedly connected to the outer wall of the first support rod. A guide plate is fixedly connected to the inner wall of the tank.
[0007] Furthermore, a support rod two is fixedly connected to the outer wall of the connecting rod two, and a connecting block two is fixedly connected to one end of the support rod two.
[0008] Furthermore, an upper scraper is fixedly connected to the outer wall of the second connecting block, and the outer wall of the upper scraper is slidably connected to the inner wall of the tank.
[0009] Furthermore, a lower scraper is fixedly connected to one end of the support rod, and the outer wall of the lower scraper is slidably connected to the inner wall of the tank.
[0010] Furthermore, a flange is fixedly connected inside the tank, and a pipe is fixedly connected to the outer wall of the flange.
[0011] Furthermore, a fixing block is fixedly connected inside the pipe, and a connecting block three is fixedly connected to one side of the outer wall of the fixing block.
[0012] Furthermore, a filter basket is rotatably connected inside the connecting block three, and a connecting block one is fixedly connected to the outer wall of the filter basket.
[0013] Furthermore, the outer wall of the connecting block is rotatably connected to the inner wall of the pipe, a filter pad is fixedly connected inside the pipe, and a flange is provided at one end of the pipe.
[0014] This utility model has the following beneficial effects:
[0015] 1. In this utility model, the motor drives the second connecting rod and the first connecting rod to rotate clockwise. The second connecting rod drives the first stirring roller to rotate. When the second connecting rod is stirring, it breaks up any lumps of paint material. The first support rod connects and fixes the first connecting rod and the second stirring roller. The first connecting rod drives the second stirring roller to rotate, pushing the paint located in the center to the upper and lower sides to prevent it from sinking or floating. The guide plate enhances the exchange between the upper and lower stirring chambers and blocks lumps of paint material, thereby improving the practicality of the device.
[0016] 2. In this utility model, the second support rod drives the upper scraper connected to the second connecting block to scrape the upper mixing chamber wall, and the first support rod drives the lower scraper to scrape the lower mixing chamber wall. This avoids material waste, reduces material loss, and lowers production costs. The mixed coating flows into the pipeline through the first flange, where it is intercepted by the filter basket connected by the fixed block and the third connecting block. Any remaining clumps of coating and impurities can be removed for cleaning by rotating the first connecting block. This is simple and quick. Furthermore, a filter pad is used for secondary filtration, which improves the practicality of the device. Attached Figure Description

[0024] 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.

One end of the second connecting rod 17 is fixedly connected to the output end of the motor 4, and one end of the first connecting rod 13 is fixedly connected to the other end of the second connecting rod 17. The inner wall of the first mixing roller 11 is fixedly connected to the outer wall of the second connecting rod 17. The second connecting rod 17 drives the first mixing roller 11 to rotate. The second connecting rod 17 is a serrated dispersion disc, which breaks up any lumps of paint material during mixing, effectively preventing clumping. A support rod 16 is fixedly connected inside the first connecting rod 13, and a support rod 16 is fixedly connected to the outer wall of the support rod 16. The stirring roller 14 and connecting rod 13 are spiral-type stirrers that drive the stirring roller 14 to rotate, pushing the coating material located at the center to the upper and lower sides to prevent the coating material from sinking or floating. A guide plate 12 is fixedly connected to the inner wall of the tank 1. The guide plate 12 divides the downward jet generated by the stirring roller 11 into a main stream after impacting the conical surface, which flows obliquely along the conical surface towards the tank wall to form a large circulation, and into tributaries that fall vertically through the holes to enhance the exchange between the upper and lower chambers. A support rod 19 is fixedly connected to the outer wall of the connecting rod 17. A connecting block 18 is fixedly connected to one end of the support rod 19.
[0027] Reference Figure 1 , Figure 4 and Figure 5 A scraper 10 is fixedly connected to the outer wall of connecting block 2 18. The scraper 10 is used to scrape off the coating on the inner wall of the upper mixing chamber, thereby avoiding material waste caused by long-term adhesion to the inner wall of the upper mixing chamber, reducing material loss and lowering production costs. The outer wall of the scraper 10 is slidably connected to the inner wall of tank 1. A lower scraper 15 is fixedly connected to one end of support rod 16. The lower scraper 15 is used to scrape off the coating on the inner wall of the lower mixing chamber, thereby avoiding material waste caused by long-term adhesion to the inner wall of the lower mixing chamber, reducing material loss and lowering production costs. The outer wall of the lower scraper 15 is slidably connected to the inner wall of tank 1. The body 1 is internally fixedly connected to a flange 5. The outer wall of the flange 5 is fixedly connected to a pipe 6. The pipe 6 is internally fixedly connected to a fixing block 20. The outer wall of the fixing block 20 is fixedly connected to a connecting block 3 21. The connecting block 3 21 is rotatably connected to a filter basket 22.

The pipe 6 is internally fixedly connected to a filter pad 23. The filter pad 23 performs secondary filtration. One end of the pipe 6 is equipped with a flange 2 8.
[0028] Working Principle: When using the anti-caking mixing device for paint processing to prevent paint from caking, the paint raw material is added into the tank 1 through the inlet 2. The inlet 2 is then closed, and the motor 4 is started. The motor 4 drives the connecting rod 17 and the first connecting rod 13 to rotate clockwise. The connecting rod 17 drives the first stirring roller 11 to rotate. During stirring, the connecting rod 17 breaks up any caking paint raw material. The support rod 16 connects and fixes the connecting rod 13 and the second stirring roller 14. The connecting rod 13 drives the second stirring roller 14 to rotate, pushing the paint located in the center upwards and downwards to prevent it from settling or floating. The guide plate 12 enhances the exchange between the upper and lower mixing chambers and prevents caking. To prevent the coating material from clumping, support rod 219 drives the upper scraper 10, which is connected to connecting block 218, to scrape the upper mixing chamber wall. Support rod 16 drives the lower scraper 15 to scrape the lower mixing chamber wall. The mixed coating flows into pipe 6 through flange 15. The filter basket 22, connected by fixing block 20 and connecting block 321, intercepts any remaining clumped coating and impurities. The filter basket 22 can be removed for cleaning by rotating connecting block 17, which is simple and quick. A filter pad 23 performs secondary filtration, and the coating then flows into storage tank through flange 28. When the tank needs to be cleaned, the tank cover 3 is opened for cleaning. Support frame 9 supports the entire device for stable operation.
