Description

Technical Field

[0001] The utility model relates to the technical field of chemical industry, in particular to a chemical solution filter. Background Art

[0002] In the petrochemical industry, filters are often used to filter tiny impurities in chemical solutions. During the filtration process, due to the excessive viscosity and poor fluidity of some chemical solutions, the effect of direct backwashing of the filter elements inside the filter is poor. Generally, the filter elements are replaced regularly to ensure the filtration effect.

[0003] When some filters are filtering impurities in petrochemical solutions, the device body is not convenient for pressure relief protection of the petrochemical solutions, and the filter element arranged inside the device body is not convenient for disassembly and replacement. Therefore, a chemical solution filter is proposed to address the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a chemical solution filter, which is used to solve the problem that when some filters are filtering impurities in petrochemical solutions, the device body is not convenient for pressure relief protection of petrochemical solutions, and the filter element arranged inside the device body is not convenient for disassembly and replacement.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] The filter is connected with the filter housing, and the filter housing is connected with the filter housing.

[0007] Preferably, when the filtering device is assembled, the cylindrical shell and the sealing silicone layer are slidably inserted.

[0008] Preferably, the rear end of the cylinder shell is in close contact with the inner wall of the rear end of the sleeve shell, and the front end of the sleeve shell is in engagement contact with the cylinder plate.

[0009] Preferably, the bottom of the housing is in contact with the frame plate, and the outer side of the column tube is in contact with the inner wall of the rubber ring.

[0010] Preferably, the preset threaded holes of the frame plate and the preset threaded holes of the casing are arranged by external stud thread assembly.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] In the utility model, the booster pump connected to the feed pipe is started to transport the petrochemical solution to the inside of the hollow pipe head and it gushes out. The petrochemical solution fills the inside of the truncated cone shell and then enters the column tube and is transported upward. The fine impurities contained in the petrochemical solution are adsorbed by the honeycomb filter element, and then the petrochemical solution is discharged through the discharge pipe. The electric control safety valve presets the safety pressure parameter through the external PLC controller. When the hydraulic pressure inside the truncated cone shell exceeds the safety pressure parameter preset by the PLC controller, the electric control safety valve automatically opens the passage to divert and relieve the pressure of the liquid inside the truncated cone shell. When the filter device is assembled, the cylinder shell and the sealing silicone layer are slid backward and inserted until the rear end of the cylinder shell is in contact with the inner wall of the rear end of the sleeve shell, and the front end of the sleeve shell is in contact with the cylinder plate. Through the above arrangement, when the filter filters the petrochemical solution, the device body is convenient for pressure relief protection of the petrochemical solution, and the filter element arranged inside the device body is convenient for disassembly and replacement.

A cylinder plate 24 is provided at the front end of the casing 21, and a cylinder shell 25 is symmetrically fixedly provided at the rear end of the cylinder plate 24. A honeycomb filter element 26 is fixedly provided between the bottoms of the cylinder shells 25 provided on the left and right sides, and a rubber ring 27 is fixedly provided inside the bottom end of the casing 21.

[0029] When the filter device 2 is assembled, the cylindrical shell 25 and the sealing silicone layer 22 are slidably inserted into each other. Through the above arrangement, the sealing silicone layer 22 and the cylindrical shell 25 are waterproof and sealed after installation.

[0030] The rear end of the cylindrical shell 25 is in contact with the rear end inner wall of the sleeve shell 21, and the front end of the sleeve shell 21 is in contact with the cylindrical plate 24. Through the above arrangement, the plug-in placement structure of the internal components of the filter device 2 is formed.

[0031] The bottom of the housing 21 is in contact with the frame plate 17 , and the outer side of the column tube 16 is in contact with the inner wall of the rubber ring 27 . Through the above arrangement, a plug-in placement structure of the mixing device 1 and the filtering device 2 is formed.

[0032] The preset threaded holes of the frame plate 17 and the preset threaded holes of the casing 21 are arranged by threaded assembly with external studs. Through the above arrangement, it is convenient to assemble and fix the mixing device 1 and the filtering device 2 through the external studs.

[0033] Working process: The utility model provides a chemical solution filter. The device body is convenient for pressure relief protection of petrochemical solutions, and the filter element arranged inside the device body is convenient for disassembly and replacement, and the device body is convenient for assembly.

[0034] The cylindrical plate 24, the cylindrical shell 25 and the honeycomb filter element 26 are an integrated filter element. When assembling the filter device 2, manually hold the handle fixed at the front end of the cylindrical plate 24, slide the cylindrical shell 25 and the sealing silicone layer 22 backward and insert them until the rear end of the cylindrical shell 25 is in contact with the rear end inner wall of the sleeve shell 21, and the front end of the sleeve shell 21 is in contact with the cylindrical plate 24, completing the installation of the integrated filter element inside the filter device 2, wherein the sealing silicone layer 22 and the cylindrical shell 25 are in contact with each other for waterproof sealing.

The electronically controlled safety valve 14 presets the safety pressure parameter through the external PLC controller. When the hydraulic pressure inside the conical shell 11 exceeds the safety pressure parameter preset by the PLC controller, the electronically controlled safety valve 14 automatically opens the passage to divert and relieve the pressure of the liquid inside the conical shell 11. When the hydraulic pressure inside the conical shell 11 is within the safety pressure parameter preset by the PLC controller, the electronically controlled safety valve 14 automatically disconnects the passage to improve the safety of the device body.
