Description

Technical Field

[0001] This utility model relates to the chemical industry, and in particular to a core-pulling stirring tank for water-based coatings. Background Technology

[0002] Water-based coatings are complex systems composed of multiple components, including resins, pigments and fillers, additives (such as dispersants, wetting agents, defoamers, thickeners, etc.) and water. These components may separate into layers due to density differences after standing for a period of time. In particular, pigments and fillers may settle to the bottom of the container. Stirring can redisperse these components to ensure that the coating reaches a uniform state before application, avoiding problems such as color difference, uneven gloss, or reduced hiding power during coating.

[0003] In the existing technology, conventional mixing equipment can only drive the coating to move in one direction during mixing. The uniformity of mixing is poor due to the rotation and mixing in one direction, and the material at the bottom layer is difficult to mix with the material at the top layer. The mixing time is longer, and the mixing efficiency is low and the output rate is poor. Utility Model Content

[0004] The purpose of this invention is to solve any of the problems in the above-mentioned technologies, thereby providing a core-pulling stirring tank for water-based coatings.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a core-pulling mixing tank for water-based coatings, comprising a mixing tank for holding the coating to be mixed and a motor fixedly installed at the center of its bottom, a rotatable mixing shaft installed inside the mixing tank, the mixing shaft being fixedly sleeved on the output shaft of the motor and rotating therewith, and multiple pump chambers provided inside the mixing tank, including pump 6.

[0006] The pressure chamber is equipped with a pump rod that can float up and down, and the bottom of the pump rod abuts against the annular drive platform of the stirring shaft.

[0007] Furthermore, the main body of the mixing tank is cylindrical with support feet at the four corners of the bottom. A motor platform is located in the middle of the four corners of the bottom of the mixing tank, and the motor is fixed at the center of the bottom of the motor platform. A central shaft seat is located at the center of the cylindrical mixing tank, and four hollow cylindrical pump chambers are arranged in a circular array around the central shaft seat. Multiple feed slots penetrating into the internal cavity are provided on the bottom side wall of the pump chamber, and a floating shaft seat is located at the center of the bottom of the pump chamber.

[0008] Furthermore, a pump rod is installed inside the pump chamber of the mixing tank. The pump rod is a T-shaped frustum with a rounded bottom. The upper frustum of the pump rod is slidably embedded in the inner wall of the pump chamber, and the lower round rod slides through the floating shaft seat. The bottom rounded end of the pump rod abuts against the mixing shaft, and a downward pressure spring is installed between the top of the pump rod and the top surface of the inner wall of the pump chamber.

[0009] Furthermore, the stirring shaft has a central shaft rod at its center, which rotates through the central shaft seat. The side wall of the central shaft rod is provided with four stirring racks arranged in a circular array. The bottom periphery of the central shaft rod is provided with an annular drive platform. The outer edge of the annular drive platform is a ring with a certain angled top surface. The top of the inclined frustum of the annular drive platform abuts against the bottom round head of the pump rod. The bottom center of the stirring shaft is provided with a connecting hole, which is fixedly fitted onto the output shaft of the motor.

[0010] The beneficial effects of this invention are as follows: the stirring frame on the side of the stirring shaft provides unidirectional pushing and stirring of the water-based coating when it rotates; the annular drive platform of the stirring shaft drives the pump rod to slide up and down in the pump chamber while rotating; when the pump rod slides up and down, a negative pressure is generated in the pump chamber, which draws the coating into the pump chamber, mixes and compresses it, and then pumps it out; the coating pumped out between multiple pump chambers will have a good convection and turning effect on the coating while being flushed, which makes the mixing uniformity better and the stirring efficiency higher.

[0020] In a specific embodiment, the pump chambers 13 are symmetrically distributed at the four corners inside the mixing tank 1. When the pump chambers 13 pump out the coating, the coating pumped out between adjacent pump chambers 13 will be mixed by counter-current mixing, making the upper and lower layers of the coating move more violently.

A downward pressure spring 5 is provided between the top of the pump rod 3 and the top surface of the inner wall of the pump chamber 13.

[0022] In a specific embodiment, when the pump rod 3 slides up and down, a negative pressure is generated in the pump chamber 13, which draws the paint into the pump chamber 13, mixes and compresses it, and then pumps it out. The paint pumped out between multiple pump chambers 13 will have a good convection and mixing effect on the paint while being flushed.

[0023] Preferably, the center of the stirring shaft 2 is a central shaft 21, which is rotatably inserted into the central shaft seat 12. The side wall of the central shaft 21 is provided with four circumferentially arranged stirring racks 22. The bottom periphery of the central shaft 21 is provided with an annular drive platform 23. The outer edge of the annular drive platform 23 is an annular shape with a certain angled top surface. The top of the inclined frustum of the annular drive platform 23 abuts against the bottom round head of the pump rod 3. The bottom center of the stirring shaft 2 is provided with a connecting hole 23, which is fixedly sleeved on the output shaft of the motor 4.

[0024] In a specific embodiment, the stirring frame 22 on the side of the stirring shaft 2 provides unidirectional pushing and stirring of the water-based coating when it rotates, and the annular drive platform 23 of the stirring shaft 2 drives the pump rod 3 to slide up and down in the pump chamber 13 while rotating.
