[0002] In order to improve the corrosion resistance of the pipeline, it is often necessary to perform polyethylene coating operations on the pipeline. In order to ensure that the polyethylene coating is quickly shaped, polyethylene coating auxiliary cooling equipment is required. The utility model patent with patent application number CN202121156893.0 discloses a polyethylene coated complex pipe cooling equipment for pipes, including a flipping mechanism rotatably supported on a base and driven to rotate by a first reduction motor; a rotating mechanism is provided on the flipping mechanism, and the rotating mechanism includes two driving wheels that are driven to rotate synchronously by a second reduction motor; a column is also vertically fixed on the flipping mechanism through a rotating disk, and a clamping lifting mechanism is provided on the side wall of the column through a linear slide rail, a slider, and a screw drive frame; the screw is connected to the third reduction motor; the clamping lifting mechanism includes a clamping arm horizontally connected to the slider, and the bottom of the clamping arm is connected to a clamping wheel mechanism; the clamping wheel mechanism includes two clamping wheels; the mirror surface of the two clamping wheels and the mirror surface of the two driving wheels are the same vertical plane. The present invention can automatically rotate the pipe axially and flip it radially at the same time, which accelerates cooling and is convenient and quick. According to the technical solution disclosed therein, when the existing polyethylene plastic coating auxiliary cooling equipment is used, on the one hand, during the blowing cooling operation, the polyethylene coated on the pipe is easily deformed due to the blowing of the airflow, which is not conducive to ensuring the quality of the polyethylene plastic coating. On the other hand, during the cooling operation, the environment is easily polluted due to the volatilization of organic gases in the polyethylene plastic coating material.

[0003] Therefore, how to design a polyethylene plastic-coated auxiliary cooling device has become our current problem to be solved. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a polyethylene plastic-coated auxiliary cooling device to solve the problems raised in the above-mentioned background technology. The utility model is reasonably designed and convenient to use, and is suitable for cooling polyethylene plastic-coated pipes.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a polyethylene plastic-coated auxiliary cooling device, comprising a sleeve and an inlet, an air inlet assembly installed on the top of the sleeve, the air inlet assembly comprising a wind tube and a fan 1, a filter assembly installed on the wind tube, the filter assembly comprising a filter screen and a cone mouth, a cooling assembly installed on the inner side of the sleeve, the cooling assembly comprising a spiral plate and a through port, an exhaust assembly installed on the bottom of the sleeve, the exhaust assembly comprising a guide sleeve and a ferrule, a purification assembly installed on the inner side of the ferrule, the purification assembly comprising an activated carbon plate and a fan 2.

[0006] Furthermore, the inlet is opened at the center of one end of the sleeve, and the outlet is opened at the center of the other end of the sleeve.

[0007] Furthermore, the top of the cone is welded to the bottom of the wind tube, the bottom of the cone is communicated with the inner side of the sleeve, and the fan is installed on the inner side of the wind tube by bolts.

[0008] Furthermore, the outer side of the spiral plate is welded to the inner wall of the other end of the sleeve, and the inner diameter of the spiral on the inner side of the spiral plate is equal to the inner diameter of the inlet.

[0009] Furthermore, the through port is opened at the bottom of one end of the sleeve, a connecting pipe is welded to the bottom of the sleeve, and the bottom of the connecting pipe is welded to the top of the guide sleeve.

[0010] Furthermore, the guide sleeve is connected to the inner side of the sleeve through a connecting pipe and a through port, and the clamping sleeve is welded to one end of the guide sleeve.

[0011] Furthermore, the activated carbon plate is clamped on the inner side of the clamping sleeve, and the second blower is installed on the inner side of the clamping sleeve by bolts.

[0012] Furthermore, a partition screen is installed on the outer side of the ferrule through bolts, and the filter screen is installed on the top of the air duct through bolts.

[0013] Beneficial effects: 1. When the polyethylene plastic coating auxiliary cooling device is in use, the pipe that has completed the polyethylene plastic coating operation is passed through the inlet into the inner side of the sleeve, and the fan filters the air through the filter and blows it into the inner side of the sleeve through the wind tube and the cone mouth. The airflow flows in a spiral along the spiral gap of the spiral plate on the inner side of the sleeve and on the outer side of the pipe, thereby increasing the airflow speed on the pipe surface and improving the cooling efficiency. The airflow gradually flows out through the through port at the bottom of the left end of the sleeve, thereby gradually reducing the airflow speed in the sleeve, so that the cooling airflow on the outer side of the pipe that has completed the polyethylene plastic coating operation gradually decreases, and then the polyethylene is first shaped with a slow airflow to avoid the polyethylene being deformed due to excessively fast airflow, thereby ensuring the quality of the polyethylene plastic coating of the pipe.

[0014] 2. When the polyethylene plastic-coated auxiliary cooling device is in use, the gas enters the inner side of the connecting pipe through the through-hole, and the second fan generates suction on the guide sleeve through the ferrule, sucking the airflow into the inner side of the ferrule, and then after purification and adsorption by the activated carbon plate, the air is blown out through the ferrule, effectively utilizing the activated carbon plate to remove volatile organic gases, preventing organic gases from drifting into the air, avoiding air pollution, and ensuring environmental safety.

The airflow gradually flows out through the through port 9 at the bottom of the left end of the sleeve 1, thereby gradually reducing the airflow speed in the sleeve 1, so that the cooling airflow on the outer side of the pipe where the polyethylene coating operation is completed gradually decreases, thereby first using a slow airflow to shape the polyethylene to avoid polyethylene being deformed due to excessively fast airflow, thereby ensuring the quality of the polyethylene coating of the pipe.

When in use, the pipe that has completed the polyethylene plastic coating operation is passed into the inner side of the sleeve 1 through the inlet 2.
