Description

Technical Field

[0001] This utility model relates to the field of anti-corrosion coating production technology, and more specifically, to a mixing and grinding device for producing anti-corrosion coatings that is easy to clean. Background Technology

[0002] Anti-corrosion coating mixing and grinding is a process in which raw materials such as resin, pigments, fillers, and additives are uniformly mixed through high-speed dispersion and fine grinding. This process typically uses sand mills or ball mills, which effectively break up particle aggregates and optimize particle size distribution through mechanical shearing force and the collision action of grinding media.

[0003] A search revealed CN217830153U, which discloses a mixing and grinding device for the production of anti-corrosion coatings. The technical solution includes: a base, a shell, and a grinding tank. The shell is welded to the upper surface of the base. A stirrer is installed inside the lower end of the shell. Slide rails are symmetrically welded to the inner wall of the upper end of the shell. A movable frame is arranged above the slide rails. Pulleys are symmetrically welded to both sides of the lower surface of the movable frame. A screening plate is located in the center of the movable frame. A grinding tank is located inside the upper end of the shell. A first grinding roller is located inside the grinding tank, and second grinding rollers are symmetrically arranged on both sides of the first grinding roller. This invention allows for easy and flexible pulling out of the movable frame via pulleys and slide rails, enabling the removal of raw materials clogging the sieve holes on the screening plate. The material can then be re-input into the grinding tank for further grinding, preventing a deterioration in the filtration effect of the screening plate and greatly improving the practicality of the device.

[0004] However, in practical applications, the aforementioned mixing and grinding device still has certain limitations. For example, although the design facilitates the disassembly and cleaning of the screening plate to maintain the filtration effect, the operation of the upper grinding roller must be paused during the cleaning process to prevent the raw materials from directly entering the next process without screening. While this operation ensures the grinding accuracy of the raw materials, frequent downtime for maintenance will have a certain impact on the overall production efficiency. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a mixing and grinding device for the production of anti-corrosion coatings that is easy to clean, so as to solve the problem that although some grinding devices in the prior art are easy to clean the screening plate, they need to be stopped during cleaning, which reduces production efficiency while ensuring accuracy.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a mixing and grinding device for the production of anti-corrosion coatings that is easy to clean, comprising...

[0007] The base has a housing fixedly installed on its top. A feed inlet is fixedly sleeved in the middle of the top of the housing. A grinding roller is provided in the inner cavity of the top of the housing. A mixing tank is provided in the inner cavity of the bottom of the base. A stirring motor is fixedly installed on the lower surface of the middle of the mixing tank. A main shaft is fixedly sleeved on the output end of the stirring motor. Several stirring rods are fixedly installed on the outer surface of the main shaft.

[0008] The filter plate is inclinedly disposed in the inner cavity of the middle of the base, and the outer surfaces on both sides along the length direction are slidably installed with the inner walls on both sides of the base. A vibration mechanism is provided directly below the filter plate, and a circulating material return mechanism is provided on the side of the filter plate along the length direction near the back of the machine.

[0009] The circulating material return mechanism includes a receiving plate 1. The outer surface of the receiving plate 1 is fixedly sleeved with the inner wall of one side of the back of the base, and its side edge in the length direction is slidably installed with the side edge of the filter plate. The bottom of the receiving plate 1 away from the filter plate is open. A receiving plate 2 is fixedly installed on the lower surface of the receiving plate 1. The bottom of the receiving plate 2 is inclined. A feed pipe is fixedly sleeved at the end of the receiving plate 2 in the width direction. A lifting cylinder is fixedly sleeved at the bottom end of the feed pipe. A support base is fixedly installed on the lower surface of the lifting cylinder. The side of the support base is fixedly installed with the outer surface of one side of the back of the base, and a motor 2 is fixedly installed on the inner surface in the middle. An auger is fixedly sleeved at the output end of the motor 2. The outer surface of the auger is rotatably installed with the inner surface of the lifting cylinder. A discharge pipe is fixedly sleeved at the top of the lifting cylinder. The discharge pipe is inclined, and its end away from the lifting cylinder is located directly above the feed inlet.

[0010] The vibration mechanism includes a motor, the surface of which is fixedly installed on the middle of the side of the base in the width direction. A shaft is fixedly sleeved on the output end of the motor. The outer surfaces of both ends of the shaft are rotatably installed on the inner walls of both sides of the base in the width direction. Several elliptical plates are fixedly sleeved on the outer surface of the shaft. The outer edges of the several elliptical plates are in contact with the lower surface of the middle part of the filter plate.

[0011] The base has a support plate fixedly installed on its inner wall, and the upper surface of the support plate is bolted to the outer surface of the top of the mixing tank. The mixing tank is equipped with a side wall cleaning mechanism.

[0012] The sidewall cleaning mechanism includes three sleeves arranged parallel to each other vertically. The outer surface of the middle part of each of the three sleeves is fixedly sleeved with the inner surface of the main shaft. A spring is provided in the inner cavity of the middle part of the sleeve. Limiting plates are fixedly connected to both ends of the spring. The outer surface of the limiting plate is slidably sleeved with the inner surface of the end of the sleeve. A movable rod is fixedly installed on the side of the limiting plate away from the spring. The outer surface of one end of the movable rod is slidably sleeved with the end of the sleeve, and a scraper is fixedly installed on the other end. The side of the scraper is in contact with the inner wall of the mixing tank.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In the above scheme, by setting up a filter plate and a circulating material return mechanism, raw material particles that do not meet the required particle size specifications filtered at the top of the filter plate will fall into the receiving plate after the side edge of the filter plate is flush with the receiving plate one, and then be discharged from the opening into the inside of the receiving plate two. They will then be collected at the feed pipe through the bottom inclined surface of the receiving plate two. Next, the raw material particles will flow into the lifting cylinder through the feed pipe. After the motor two is started, the auger connected to its output end will rotate inside the lifting cylinder and convey the raw material particles upward. Finally, after the raw material particles reach the top of the lifting cylinder, they will be added back into the base from above the feed port along the inner surface of the discharge pipe to participate in the grinding process. In this way, the conveying action of the inclined filter plate and the circulating material return mechanism can clean and return large-diameter raw material particles, ensuring the filtration effect of the filter plate while eliminating the need for frequent machine shutdowns for cleaning, thus improving the actual production efficiency.

[0015] In the above solution, by setting up a side wall cleaning mechanism and other structures, during the mixing of raw materials inside the mixing tank by the stirring motor driving the main shaft and stirring rod, three sleeves connected to the top, bottom, and middle of the main shaft rotate synchronously, driving the sleeved movable rod to rotate. This causes the scraper connected to the end of the movable rod to move against the inner wall of the mixing tank. This not only stirs the raw materials in areas that the stirring rod cannot reach, but also scrapes and cleans the raw materials adhering to the inner wall of the mixing tank. In addition, the spring set in the middle of the sleeve cavity pushes the limiting plate connected to both ends. The limiting plate further pushes the movable rod, so that under the elastic action of the spring, the scraper connected to the end of the movable rod adheres to the inner wall of the mixing tank. This solution can be adapted to the use of mixing tanks of different diameters. Thus, the side wall cleaning mechanism sleeved inside the main shaft can more thoroughly mix the raw materials inside the mixing tank, and can also scrape off the raw materials adhering to the inner wall of the mixing tank, reducing residue and facilitating subsequent cleaning of the mixing tank.

[0022] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0023] As attached Figure 1 To be continued Figure 4 An embodiment of this utility model provides a mixing and grinding apparatus for the production of anti-corrosion coatings that is easy to clean, including...

[0024] A base 1 is provided, and a housing 2 is fixedly installed on the top of the base 1. A feed inlet 3 is fixedly sleeved in the middle of the top of the housing 2. A grinding roller 4 is provided in the inner cavity of the top of the housing 2. A mixing tank 8 is provided in the inner cavity of the bottom of the base 1. A stirring motor 10 is fixedly installed on the lower surface of the middle of the mixing tank 8. A main shaft 11 is fixedly sleeved at the output end of the stirring motor 10. Several stirring rods 12 are fixedly installed on the outer surface of the main shaft 11.

[0025] The filter plate 5 is inclinedly arranged in the inner cavity of the middle of the base 1, and the outer surfaces on both sides of the length direction are slidably installed with the inner walls on both sides of the base 1. A vibration mechanism 6 is arranged directly below the filter plate 5, and a circulating material return mechanism 7 is arranged on the side of the filter plate 5 near the back of the machine box 2 in the length direction.

[0026] The recycling mechanism 7 includes a receiving plate 70, the outer surface of which is fixedly sleeved with the inner wall of the back side of the base 1, and the side edge along the length direction is slidably installed with the side edge of the filter plate 5. The bottom of the receiving plate 70 on the side away from the filter plate 5 is open. A receiving plate 71 is fixedly installed on the lower surface of the receiving plate 70. The bottom of the receiving plate 71 is inclined. A feed pipe 72 is fixedly sleeved at the end of the receiving plate 71 in the width direction. A lifting device is fixedly sleeved at the bottom end of the feed pipe 72. The lifting cylinder 76 has a support base 73 fixedly installed on its lower surface.

The top end of the lifting cylinder 76 is fixedly sleeved with a discharge pipe 77. The discharge pipe 77 is inclined, and the end away from the lifting cylinder 76 is located directly above the feed inlet 3.

[0027] The vibration mechanism 6 includes a motor 60, whose surface is fixedly installed at the center of the side of the base 1 in the width direction. A shaft 61 is fixedly sleeved at the output end of the motor 60.

Several elliptical plates 62 are fixedly sleeved on the outer surface of the shaft 61. The outer edges of the elliptical plates 62 are in contact with the lower surface of the middle part of the filter plate 5. By setting the vibration mechanism 6, when the filter plate 5 filters the ground raw material, the motor 60 can be started. The shaft 61 sleeved at its output end rotates, which drives the sleeved elliptical plates 62 to rotate. As the elliptical plates 62 rotate, the filter plate 5, which is in contact with the outer edges of the elliptical plates 62, exhibits an up-and-down vibration effect according to the change in the diameter of the elliptical plates 62 during the rotation, thereby improving the filtration efficiency of the raw material and assisting the large-particle-size raw material to roll down towards the recycling mechanism 7.

[0028] Among them, a support plate 9 is fixedly installed on the inner wall of the bottom of the base 1, and the upper surface of the support plate 9 is bolted to the outer surface of the top of the mixing tank 8. The inner cavity of the mixing tank 8 is provided with a side wall cleaning mechanism 13.

[0029] The side wall cleaning mechanism 13 includes a sleeve 130, three sleeves 130 are arranged in parallel vertically, and the outer surface of the middle part of each of the three sleeves 130 is fixedly sleeved with the inner surface of the main shaft 11. A spring 131 is provided in the inner cavity of the middle part of the sleeve 130. Limiting plates 133 are fixedly connected to both ends of the spring 131. The outer surface of the limiting plate 133 is slidably sleeved with the inner surface of the end of the sleeve 130. A movable rod 132 is fixedly installed on the side of the limiting plate 133 away from the spring 131. The outer surface of one end of the movable rod 132 is slidably sleeved with the end of the sleeve 130, and a scraper 134 is fixedly installed on the other end. The side of the scraper 134 is in contact with the inner wall of the mixing tank 8.

[0030] The working process of this utility model is as follows:

[0031] During the production of anti-corrosion coatings, raw materials such as resin, pigment, filler and additives can be added to the interior of the base 1 through the feed port 3. After being crushed and ground by the grinding roller 4 in the inner cavity of the top of the base 1, they fall into the filter plate 5 for screening. Raw material particles that meet the required particle size specifications will continue to fall into the interior of the mixing tank 8. Then, the stirring motor 10 is controlled to drive the main shaft 11 to rotate, so that several stirring rods 12 connected to the surface of the main shaft 11 stir and mix the raw materials inside.

[0032] In the above production process, the raw material particles that do not meet the required particle size specifications filtered by the top of the filter plate 5 will fall into the receiving plate 70 through the inclined surface of the filter plate 5 after the side edge of the filter plate 5 is flush with the receiving plate 70. Then, they will be discharged from the opening into the inside of the receiving plate 71 and collected at the feed pipe 72 through the inclined surface at the bottom of the receiving plate 71. Then, the raw material particles will flow into the lifting cylinder 76 through the feed pipe 72. After the motor 74 is started, the auger 75 connected to its output end will rotate inside the lifting cylinder 76 and convey the raw material particles upward. Finally, after the raw material particles reach the top of the lifting cylinder 76, they will be added back into the inside of the base 1 from above the feed port 3 along the inner surface of the discharge pipe 77 to participate in the grinding process.

[0033] During the mixing process of the mixing drum 8 by the stirring motor 10 driving the main shaft 11, stirring rod 12 and other structures, the three sleeves 130 connected to the top, bottom and middle of the main shaft 11 will rotate synchronously, and drive the sleeved movable rod 132 to rotate. This causes the scraper 134 connected to the end of the movable rod 132 to move against the inner wall of the mixing drum 8. This not only stirs the raw materials in the area that the stirring rod 12 cannot reach, but also scrapes and cleans the raw materials adhering to the inner wall of the mixing drum 8 using the scraper 134. In addition, the spring 131 set in the middle of the inner cavity of the sleeve 130 will push the limiting plate 133 connected at both ends. The limiting plate 133 further pushes the movable rod 132, so that under the elastic action of the spring 131, the scraper 134 connected to the end of the movable rod 132 will adhere to the inner wall of the mixing drum 8. This method can be adapted to the use of mixing drums 8 with different diameters.
