Description

Technical Field

[0001] This utility model relates to the field of coating technology, and in particular to a coating impurity separation device. Background Technology

[0002] Paint is a viscous liquid that is applied to the surface of an object to be protected or decorated and forms a continuous film that adheres firmly to the object. It is usually based on resin, oil, or emulsion, with or without pigments and fillers, and with appropriate additives, and is prepared with organic solvents or water. During the paint production process, it is necessary to separate impurities from the paint.

[0003] A search revealed a Chinese patent (application number "202323287241.2") disclosing "a paint impurity separation device." This device includes a processing box, characterized in that: a feed hopper is fixedly installed at the right end of the processing box, a discharge port is fixedly installed at the lower end of the processing box, a pushing and squeezing assembly is provided at the top of the processing box, the pushing and squeezing assembly penetrates the top of the processing box and extends into the interior of the processing box, a filtering assembly is provided inside the processing box, and a pushing and striking assembly is provided in the inner cavity of the processing box. However, during use, when the paint is squeezed to accelerate the filtration speed, the pressure causes the paint to flow from the bottom to the top of the feed hopper, resulting in paint overflowing from the top opening of the feed hopper, thus reducing its practicality. Utility Model Content

[0004] This invention provides a paint impurity separation device, which solves the problem in the prior art that when the separation device extrudes paint to accelerate the filtration speed, the pressure causes the paint to flow from the bottom to the top of the feed hopper, resulting in paint overflowing from the top opening of the feed hopper, thus reducing its practicality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A coating impurity separation device includes a separation tank with a feeding mechanism. The feeding mechanism includes a top cover connected to the outer wall of the top of the separation tank via a flange and two conveying cylinders respectively penetrating and fixed to the outer wall of the top cover. Each of the two conveying cylinders contains a filter assembly. The filter assembly includes a limiting plate abutting against the outer wall of the top of the conveying cylinder, a connecting rod fixed to the outer wall of the bottom of the limiting plate, a fixing rod fixed to the outer wall of the bottom end of the connecting rod, a filter element slidably sleeved on the outer wall of the fixing rod, and a threaded ring screwed to the lower outer wall of the fixing rod. The separation tank is equipped with a stirring mechanism, which includes a stirring motor, a stirring shaft connected to the bottom end of the output shaft of the stirring motor via a coupling, a mounting ring connected to the outer wall of the stirring shaft via a pin, and several stirring frames respectively fixed to the outer wall of the mounting ring. One side of the separation tank is equipped with a vacuuming mechanism, which includes a mounting block fixed to the outer wall of one side of the separation tank, a vacuum pump bolted to the outer wall of one side of the mounting block, and an exhaust pipe fixed to the outer wall of the bottom of the top cover.

[0007] Preferably, a discharge pipe is fixedly provided on the inner wall of the bottom of the separation tank, and a solenoid valve is clamped and installed on the outer wall of one end of the discharge pipe.

[0008] Preferably, both conveying cylinders have equally spaced through holes on their outer walls below the top cover, and both conveying cylinders have feed pipes fixed on the upper inner walls of one side.

[0009] Preferably, the filter element is slidably sleeved inside the conveying cylinder, and a fixing opening is opened on the bottom outer wall of the conveying cylinder, with a threaded ring sleeved inside the fixing opening.

[0010] The above method involves feeding paint into a conveying cylinder through one of the feed pipes. The filter element inside the conveying cylinder filters the paint, trapping impurities within it. When a single filter element needs to be replaced, paint is fed through another feed pipe, and the filter element is pulled out by pulling the limit plate, i.e., removing the limit ring, allowing for filter element replacement.

[0011] Preferably, a mounting bracket is fixed on the top outer wall of the top cover, and the stirring motor is connected to the top outer wall of the mounting bracket by bolts. The upper part of the stirring shaft passes through and is connected to the outer wall of the top cover by bearings, and several stirring brackets abut against the inner wall of the separation tank.

[0012] Preferably, a three-way pipe is screwed onto the upper outer wall of the outlet pipe, and a gas supply pipe is screwed onto the bottom inner wall of the three-way pipe. One end of the gas supply pipe is connected to the outer wall of the vacuum pump inlet by a clamp. An exhaust pipe is screwed onto the top inner wall of the three-way pipe, and a sealing valve is clamped onto the outer wall of one end of the exhaust pipe.

[0013] The above scheme uses the output shaft of the stirring motor to rotate, which drives the stirring shaft and multiple stirring frames to rotate. The multiple stirring frames scrape off the coating on the inner wall of the separation tank. At the same time, the stirring frames stir the coating in the separation tank, causing the air in the coating to overflow. The vacuum pump operates to extract the air from the separation tank, making the separation tank a negative pressure state. Under the action of pressure difference, the coating quickly passes through the filter element.

[0014] The beneficial effects of this utility model are as follows:

[0015] The output shaft of the stirring motor rotates, driving the stirring shaft and multiple stirring frames to rotate. The multiple stirring frames scrape off the coating on the inner wall of the separation tank. At the same time, the stirring frames stir the coating in the separation tank, causing the air in the coating to escape. The vacuum pump operates to extract the air from the separation tank, making the separation tank a negative pressure state. Under the action of pressure difference, the coating passes through the filter element quickly. This can accelerate the filtration speed of the coating and prevent the coating from overflowing under pressure, thus improving its practicality. Attached Figure Description
