When the upper sealing cover is screwed in the opening end of the barrel joint, the volume and the weight of the upper sealing cover can be reduced, so that the upper sealing cover is convenient to disassemble and assemble, and the manufacturing cost is saved; the sealing ring ensures that the matching surface of the upper sealing cover keeps sealing.
Preferably, the cylinder is made of a thick-walled stainless steel pipe, and the outer diameter of the cylinder is at least 2 times the outer diameter of the connecting pipe butted on the air inlet and the air outlet. The cylinder body made of the thick-wall stainless steel pipe has high strength and good corrosion resistance; when the cylinder is more than 2 times of the outer diameter of the connecting pipeline, the integral strength of the filter can be ensured.
Preferably, the cylinder joint is welded and fixed on the cylinder. The barrel joint is welded and fixed on the barrel, so that the processing of structures such as air inlet and air outlet is convenient.
Preferably, the bottom of the barrel is provided with a sewage draining outlet. Through the drain of bottom, be convenient for clear away the impurity in the filter immediately, guarantee the filter effect.
Therefore, the utility model discloses a high pressure filter structure has following advantage: the integral structure is simple, the filter element is disassembled with time and labor conservation, and the filter element is convenient and quick, and compared with the traditional high-pressure filter with the same caliber and pressure, the weight is only about half, the material and the processing cost are saved, and the integral cost is lower; because the barrel body is thin and long, and the floor area is small, a support does not need to be arranged, and the barrel is more suitable for installation and use in various narrow spaces.
