Description

Technical Field

[0001] This utility model relates to a liquid stirring device, which is applied in the field of stirring equipment production for coating processing. Background Art

[0002] The descriptions in this section are provided only as background information relating to this disclosure and do not constitute prior art.

[0003] With social development and rising living standards, coatings can form a protective film on the surface of objects, preventing corrosion from oxygen and moisture, extending their lifespan, and also enhancing their appearance. The coating production process requires a mixer to mix the components. The coating mixer is an integral part of the coating production equipment, specifically the mixing system, which can pulverize, disperse, emulsify, and mix the coating.

[0004] A Chinese utility model patent with authorization announcement number CN219849109U discloses a mixing device for coating processing, including a mixing mechanism and a heat-insulating conveying component. A support plate is installed inside the mixing tank, the mixing mechanism is mounted on top of the support plate, and the heat-insulating conveying component is installed inside the mixing tank. A lid is hinged to the top of the mixing tank. When mixing the coating, the mixing mechanism uses an output motor to drive a mixing rod to rotate within a fixed bearing, causing the mixing blades, which are inclined at 45 degrees, to fully mix the coating, thus improving product quality. The heat-insulating conveying component provides a heater to the heating rod during mixing, increasing the mixing efficiency. An insulation layer attached to the inner surface of the mixing tank continuously keeps the mixed coating warm. A conveying pump is activated to extract the mixed coating through a connected conveying pipe. It has the following disadvantages: 1. It cannot quantitatively add materials, making it inconvenient to process and produce coatings using different materials with different ratios; 2. Residue will accumulate inside the mixing tank that holds the coating after a long period of use, and the mixing device as a whole is not easy to disassemble and clean; 3. The inner wall of the mixing tank that comes into contact with the coating is prone to coating adhesion.

[0005] Therefore, it has become an urgent task to provide a liquid stirring device that is easy to quantitatively add materials, easy to clean, and can effectively prevent coatings from adhering to the inner wall. Utility Model Content

[0006] To overcome the shortcomings of existing mixing devices, such as inability to quantitatively add materials, difficulty in cleaning, and easy adhesion of coatings to the inner wall, this utility model provides a liquid mixing device. The specially designed feeding device enables the rapid quantitative preparation of multi-component materials, allowing the materials to be quickly mixed and quantitatively added as needed, thus facilitating quantitative feeding.

[0007] The technical solution of this utility model is as follows:

The first feeding scraper is movably attached to the top of the bottom wall of the inner cavity of the feeding barrel.

[0011] The feeding scraper not only effectively prevents material from adhering to the inner wall of the feeding hopper, but also, through the rotation of at least two scrapers, drives the material in the feeding hopper to swirl and mix thoroughly. The integrated design of the feeding agitator and the feeding hopper lid facilitates quick disassembly and cleaning of the feeding device.

[0012] The feeding hopper cover includes a long strip-shaped horizontal plate that is horizontally positioned above the opening of the feeding hopper and extends radially to the top of the feeding hopper wall, and two flip-tops that are located on both sides of the horizontal plate and are rotatably connected to the horizontal plate by hinges.

The two first stirring scrapers are respectively close to the bottom wall of the top cover and the bottom wall of the inner cavity of the stirring tank and extend radially along the stirring tank to a position close to the inner cavity sidewall of the stirring tank.

[0017] The mixing scraper effectively prevents paint from adhering to the top cover and the inner wall of the mixing tank, facilitating quick and easy cleaning afterwards.

[0018] The mixing tank is provided with a first annular plate extending radially outward along the edge of the mixing tank, and the top cover is provided with a second annular plate extending radially outward along the edge of the top cover.
