Technical Field

[0001] The utility model relates to the technical field of quenching oil production, in particular to an impurity removal device for the production of quenching medium. Background Technique

[0002] Quenching oil is a process oil used as a quenching medium. The cooling capacity of the oil is insufficient in the range of 550-650°C, and the average cooling rate is only 60-100°C / s. However, in the range of 200-300°C, the slow cooling rate is very suitable for quenching. The oil is used for quenching alloy steel and small-section carbon steel, which can not only obtain satisfactory hardenability and hardenability, but also prevent cracking and reduce deformation.

[0003] There are impurities inside the quenching oil. If the impurities in the quenching oil cannot be filtered out, it will affect the later use quality of the quenching oil. However, the existing impurity removal device cannot clean the impurities at the filter surface during the working process, resulting in a large thickness of the impurity complex, a decline in the filtering and impurity removal effect, and inconvenience in cleaning the filtering structure. Therefore, an impurity removal device for the production of quenching medium is proposed for the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide an impurity removal device for the production of quenching medium to solve the above problems.

[0005] The utility model realizes the above purpose through the following technical solutions. An impurity removal device for the production of quenching medium includes a lower hood, an upper hood, a fine filter tube, a lower spring, an upper spring, a pneumatic control valve, a gas guide hose and a round hole plate. The hole in the middle of the round hole plate is in sliding contact with the surface of the fine filter tube, and the round hole plate is installed in the upper hood. The upper spring is sleeved on a part of the fine filter tube on one side of the round hole plate. The lower round cover at the bottom end of the fine filter tube is connected to the inner bottom of the lower hood through a lower spring. The part of the gas guide hose inside the fine filter tube is distributed with air injection holes. The outer end of the gas guide hose is connected to the corresponding port of the pneumatic control valve. The port of the oil inlet conduit at the inner bottom of the lower hood faces the lower round cover.

[0006] Preferably, a vortex formation baffle is installed inside the lower hood, and the outer circular ring surface of the vortex formation baffle is lower than the hood opening of the lower hood.

[0007] Preferably, the inner diameter of the outer circular ring surface of the vortex formation baffle is much larger than the diameter of the fine filter tube.

[0008] Preferably, the top port of the fine filter tube is sealed with an upper round cover, and the middle part of the upper round cover is fixedly connected to the corresponding part of the gas guide hose.

[0009] Preferably, the hood opening of the lower hood and the hood opening of the upper hood are threadedly connected to each other.

[0010] Preferably, an oil outlet duct is connected and installed on the upper hood.

[0011] Compared with the prior art, the advantages of the present utility model are as follows: the impact change of the oil flow velocity flowing out through the oil inlet conduit on the lower round cover directly in front, combined with the upper spring and the lower spring distributed above and below the fine filter tube, achieves the effect of the up-and-down movement of the fine filter tube. At the same time, the up-and-down fine filter tube is in sliding contact with the round holes on the round hole plate, which is conducive to scraping off the impurities attached to the surface of the fine filter tube and falling off, always maintaining the use state where the filter surface is free of impurity blockage. The eddy current forming baffle is used to form an eddy current on one side inside the lower hood, which helps to retain the scraped-off impurities in the eddy current area and reduce the influence on the filter surface of the fine filter tube. The air injection holes distributed on a part of the air guide hose located inside the fine filter tube are used to clean the impurities in the fine filter tube in the reverse direction.
