[0025] As shown in Figure 3 and Figure 4 , the pressing assembly comprises an annular plate 8 arranged at the bottom of the air inlet pipe 3, the inner wall end face of the butt pipe 6 is provided with an annular groove 9, the annular plate 8 is located in the annular groove 9, and a plurality of first springs 10 are fixedly connected between the bottom surface of the annular plate 8 and the bottom surface of the annular groove 9.

[0026] Among them, the pressure of the air inlet pipe 3 entering the butt pipe 6 can be used to drive the first trapezoidal block 13 to extrude the sealing ring 12 by using the pressing assembly, so as to realize efficient sealing treatment of the air inlet pipe 3, without manual sealing, which has high convenience and practicality.

[0027] As shown in Figure 5 , the sealing assembly comprises a groove 11 arranged in the inner wall of the butt pipe 6, the groove 11 is annular, the side wall of the groove 11 is fixedly connected with a sealing ring 12, the sealing ring 12 is flush with the inner wall of the butt pipe 6, a plurality of first trapezoidal blocks 13 are movably connected in the inner cavity of the groove 11, the first trapezoidal blocks 13 are arc-shaped, a plurality of second trapezoidal blocks 17 are arranged on the outer side of the first trapezoidal blocks 13, the second trapezoidal blocks 17 are slidably connected with the side wall of the groove 11, the first trapezoidal blocks 13 abut the second trapezoidal blocks 17, the bottom surface of the second trapezoidal blocks 17 is fixedly connected with a steel wire 21, a plurality of through holes 18 are arranged in the bottom surface of the groove 11, the through holes 18 are communicated with the annular groove 9, and the other end of the steel wire 21 penetrates through the through hole 18 and is fixedly connected with the annular plate 8.

[0028] Among them, by setting the sealing assembly, the connection position of the air inlet pipe 3 and the butt pipe 6 can be effectively sealed, so as to avoid the leakage of unfiltered high-pressure gas from the connection gap between the air inlet pipe 3 and the butt pipe 6, causing the phenomenon that the gas is directly discharged without being filtered, thereby avoiding such problems, further improving the filtering effect of the gas.

[0029] As shown in Figure 5As shown, the bottom surface of the first trapezoidal block 13 is fixedly connected with a clamping block 14, the bottom surface of the groove 11 is provided with a plurality of clamping grooves 15, the clamping block 14 and the clamping groove 15 are slidably connected, and the clamping block 14 and the clamping groove 15 are fixedly connected with a second spring 16.

[0033] The working principle of the utility model is as follows: when the filter element 5 is taken out for cleaning or replacement, the top cover 2 needs to be removed first. After the filter element 5 is installed in the tank body 1, the top cover 2 is closed, the air inlet pipe 3 is inserted into the butt joint pipe 6, the air inlet pipe 3 is pressed down, the annular plate 8 is compressed, and the first spring 10 is compressed. When the annular plate 8 moves downward, the steel wire 21 is pulled down, the second trapezoidal block 17 is moved downward, the inclined surface of the second trapezoidal block 17 drives the first trapezoidal block 13 to move toward one side of the sealing ring 12, and the sealing ring 12 is pushed to tightly adhere to the air inlet pipe 3, achieving the effect of efficient sealing. When filtering gas, the specified air inlet pipe 3 can be selected according to the filtering requirements, and the corresponding valve 20 is opened, so that the gas flow of multiple pipelines can pass through the single filter element 5 for filtering, and the filtering efficiency is improved.
