Description

Technical Field

[0001] This utility model relates to the technical field of water-based paint production and processing equipment, and in particular to a water-based paint dispersion protection device. Background Technology

[0002] In the production and processing of water-based paints, the dispersion process is a crucial step that determines the quality of the product. Its core requirement is to thoroughly mix and disperse the water-based paint raw materials using agitation components. Simultaneously, it needs to address issues such as paint splashing, adhesion to the inner walls, odor diffusion, material waste, and inconvenient equipment maintenance during the dispersion process. Currently available water-based paint dispersion devices, while capable of basic mixing and dispersion functions, still have many shortcomings in terms of protection and practicality, making it difficult to meet the demands for efficient, environmentally friendly, and low-loss production. Most existing water-based paint dispersion devices adopt open or simple cover plate structures. The open design easily leads to the paint splashing due to high-speed rotation during dispersion and stirring. This not only directly wastes the water-based paint raw materials, but also contaminates the equipment surface and workshop environment. If the splashed paint comes into contact with the skin of operators, it can easily cause irritation and discomfort. Although some devices with covers can block splashing to a certain extent, the covers are mostly fixed or have poor sealing effect. Fixed covers make feeding, cleaning and maintenance operations cumbersome, while poor sealing cannot effectively prevent the dispersion of volatile components in the paint, affecting the air quality in the workshop and endangering the respiratory health of operators. Meanwhile, existing equipment generally lacks a targeted cleaning and recovery structure. Water-based paint tends to adhere to the inner wall of the tank and the inner wall of the cover plate during the dispersion process. Long-term accumulation not only affects the purity of subsequent batches of paint (due to the easy introduction of impurities), but also requires manual disassembly and cleaning of the equipment periodically. This operation is time-consuming and labor-intensive, and the residual paint is difficult to recover during the cleaning process, further increasing material loss. In addition, although some equipment has attempted to set up cleaning components, these components often require additional drive motors, which not only increases equipment costs and energy consumption, but also complicates the structure of the equipment and reduces operational stability. A few other cleaning structures are indirectly driven by the main shaft, but lack a reasonable reduction transmission design, resulting in excessively high rotation speed of the cleaning components, which is prone to abnormal wear, shortens the service life, and limits the cleaning range, making it difficult to cover both the inner wall of the tank and the inner wall of the cover plate at the same time, resulting in poor cleaning effect. Furthermore, the material dispersion uniformity and discharge convenience of existing devices need to be improved. The stirring components of some devices can only act on the middle area of ​​the tank, and the material at the bottom is prone to settle in the discharge pipe or at the bottom of the tank, resulting in uneven dispersion and affecting the quality of water-based paint products; while the discharge process mostly relies on natural flow, which is inefficient and the residual material is difficult to completely discharge, which can easily cause pipe blockage and material waste. Therefore, this utility model proposes a water-based paint dispersion protection device to solve the above problems.

[0020] Reference Figure 1-8 A water-based paint dispersion protection device includes a tank body 1, an inlet pipe 11, a vertical pipe 12, an outlet pipe 13, a top cover 2, a main shaft 3, a drive motor 31, and a rotating shaft 5; Both the feed pipe 11 and the vertical pipe 12 are fixedly installed on the tank body 1, with the vertical pipe 12 located at the center of the bottom of the tank body 1. The discharge pipe 13 is fixedly installed on the vertical pipe 12 and is equipped with a valve. The bottom side of the top cover 2 is provided with a sealing groove arranged in an annular shape. A sealing ring is fixedly installed on the top of the tank body 1. The sealing ring is sealed and snapped into the sealing groove, which facilitates the disassembly of the top cover 2 and ensures the sealing effect after the top cover 2 is installed on the top of the tank body 1. The main shaft 3 is rotatably installed on the vertical pipe 12 and extends into the tank body 1 and the top cover 2. The drive motor 31 is fixedly installed at the bottom end of the vertical pipe 12, and the output shaft of the drive motor 31 is axially fixedly connected to the main shaft 3. Multiple stirring rods 32 located inside the tank body 1 are fixedly installed on the main shaft 3. A support frame 41 is rotatably mounted on the main shaft 3. Two lower scraper blades 4 are symmetrically fixed on the support frame 41. The side of the two lower scraper blades 4 away from the main shaft 3 is in contact with the inner wall of the tank 1. The lower scraper blades 4 can clean and scrape off the water-based paint adhering to the inner wall of the tank 1 when the lower scraper blades 4 rotate based on the main shaft 3. A rotating shaft 5 is rotatably mounted on the top cover 2. The rotating shaft 5 and the main shaft 3 are located on the same vertical axis. A polygonal snap-fit ​​block 301 is fixedly mounted at the bottom end of the main shaft 3. A snap-fit ​​groove adapted to the snap-fit ​​block 301 is opened at the bottom end of the rotating shaft 5. The main shaft 3 and the rotating shaft 5 are detachably connected through the snap-fit ​​block 301 and the snap-fit ​​groove. A mounting ring is rotatably mounted on the rotating shaft 5. Two upper scraper strips 51 are symmetrically fixed on the mounting ring and contact the inner wall of the top cover 2. When the mounting ring rotates around the rotating shaft 5, it can clean the water-based paint splashed onto the inner wall of the top cover 2, effectively preventing the water-based paint from adhering to the inner wall of the top cover 2, and also effectively reducing material waste. In order to directly drive the lower scraper 4 to rotate around the main shaft 3 when the upper scraper 51 rotates around the rotating shaft 5, the bottom end of the upper scraper 51 extends into the tank body 1 and contacts the upper part of the inner side wall of the tank body 1, and the upper scraper 51 and the lower scraper 4 are staggered. A drive gear 52 is fixedly sleeved on the rotating shaft 5. The same gear disk 54 is fixedly installed on the top side of the two upper scraper blades 51. Multiple transmission gears 53 are rotatably installed on the inner wall of the top side of the top cover 2, arranged in a circular array based on the rotating shaft 5. The multiple transmission gears 53 mesh with the gear disk 54 and the drive gear 52, which can control the two upper scraper blades 51 to rotate based on the rotating shaft 5 when the rotating shaft 5 rotates. At the same time, it can achieve an effective deceleration effect and avoid abnormal wear of the upper scraper blades 51 caused by excessive speed.

[0021] In this embodiment, in order to prevent water-based paint from splashing onto the drive gear 52 and transmission gear 53, and at the same time to prevent water-based paint from adhering to the bottom side of the rotating block 501, a rotating block 501 is fixedly installed on the rotating shaft 5. The bottom side of the rotating block 501 is concave, and the upper scraper 51 is in contact with the bottom side of the rotating block 501.

[0022] In this embodiment, in order to turn over the material deposited in the vertical pipe 12 during the material processing process to avoid local unevenness, and to achieve the effect of assisting material discharge when the rotation direction of the main shaft 3 changes, a spiral blade 33 is fixedly installed on the main shaft 3, and the spiral blade 33 is located inside the vertical pipe 12.

[0023] The circuits, electronic components, and module mechanisms involved all employ existing technologies, which can be fully implemented by those skilled in the art, and need no further explanation. The content protected by this application does not involve any improvement to the software, circuits, or methods.

[0024] Working principle: In use, first connect the power supply and add the water-based paint raw material to be dispersed into the tank 1 through the feed pipe 11. At the same time, start the drive motor 31. The drive motor 31 drives the main shaft 3 to rotate, and the stirring rod 32 on the main shaft 3 rotates accordingly, which fully stirs and disperses the water-based paint in the tank 1. At the same time, the main shaft 3 drives the rotating shaft 5 to rotate synchronously through the engagement of the locking block 301 and the locking groove. When the rotating shaft 5 rotates, the drive gear 52 fixedly mounted on it drives the gear disc 5 through multiple transmission gears 53. 4. Rotation allows control of the upper scraper 51 to rotate around the pivot 5. Since the upper scraper 51 and the lower scraper 4 are staggered, the upper scraper 51 will push the lower scraper 4 during rotation, causing it to rotate around the main shaft 3. This allows the inner wall of the tank 1 to be scraped and cleaned. The upper scraper 51 cleans the water-based paint on the inner wall of the top cover 2 and the upper part of the inner wall of the tank 1. In addition, the spiral blades 33 on the main shaft 3 rotate inside the vertical tube 12, turning over the deposited material inside the vertical tube 12 to ensure uniform dispersion.

[0025] After processing, open the valve on the discharge pipe 13. By changing the rotation direction of the main shaft 3, the material can be discharged from the discharge pipe 13 with the assistance of the spiral blades 33. If it is necessary to thoroughly clean or maintain the inside of the device, the top cover 2 can be directly removed. Since the top cover 2 and the tank body 1 are connected by a sealing ring and a sealing groove, the disassembly operation is convenient and does not affect the sealing of subsequent installation.

[0026] The present invention provides a detailed description of a water-based paint dispersion protection device. Specific embodiments have been used to illustrate the principle and implementation of the present invention. These embodiments are merely illustrative and are intended to aid in understanding the method and core concept of the present invention.
