[0021] Example 1:

[0022] As Figures 1-2 ​As shown, a straight-through particle filter, comprising a shell 1, the left side of the center position of the shell 1 is provided with an air inlet, the right side of the center position of the shell 1 is provided with an exhaust port, the air inlet is communicated with the air inlet pipe 2 located outside the shell 1, the exhaust port is communicated with the exhaust pipe 3 located outside the shell 1, the air inlet pipe 2 and the exhaust pipe 3 are fixedly connected with the shell 1, the inside of the shell 1 is provided with a support frame 4, a plurality of first filter sheets 5 and second filter sheets 6 are arranged in the support frame 4 from left to right, the shell 1 is welded by the shell on the left side and the end cover on the right side, the outer wall of the first filter sheet 5 and the second filter sheet 6 is attached to the inner wall of the shell 1, the support frame 4 comprises a first circular rod, a second circular rod, a third circular rod, a first semicircular ring and a second semicircular ring, the first circular rod, the second circular rod and the third circular rod are in the shape of a triangle, one end of the first circular rod, the second circular rod and the third circular rod is fixedly connected with the first semicircular ring, the other end of the first circular rod, the second circular rod and the third circular rod is fixedly connected with the second semicircular ring, the periphery of the first filter sheet 5 and the second filter sheet 6 is provided with an acute angle obtuse shape, the end of the exhaust pipe 3 away from the shell 1 is provided with an outer wall thread, the end of the exhaust pipe 3 away from the shell 1 is screwed with an arc-shaped pipe, the left side of the support frame 4 of the shell 1 is provided with a dispersion filter screen inside the shell 1, the dispersion filter screen is a convex arc surface, a plurality of protrusions are arranged on the support frame 4 from left to right at equal intervals.

[0023] As Figure 1 and Figure 2 shown, in the design of the first filter sheet for filtering large particles, the second filter sheet for adsorbing toxic and harmful gases, through the staggered arrangement of the first filter sheet and the second filter sheet, the gas can be better filtered, the straight-through filtering process is realized, and in order to avoid the first filter sheet and the second filter sheet cannot be effectively utilized, so need to distribute the protrusions on the support frame from left to right, play the existence of interval between two adjacent first filter sheet and second filter sheet, because the diameter of the air inlet pipe is smaller than the diameter of the filter sheet, so need to pass through the dispersion filter screen to disperse the airflow entering the inside of the shell, because the entry point is located at the left center position of the shell, so set the dispersion filter screen to the arc-shaped mesh surface with the center position protruding to the left, play a better dispersion effect.

[0024] Specific implementation process: through the structure of the first filter piece and the second filter piece is not consistent, and because the outer wall of the first filter piece and the second filter piece are all attached to the inner wall of the shell, the first filter piece and the second filter piece can be fixed and installed on the support frame first, then put into the shell, and finally the fixed end cover is welded, the high-precision installation of the particle filter is realized, compared with the traditional method of directly inserting the filter piece into the shell, the filter piece installed in this way has more uniform internal distribution density, and is more convenient for batch manufacturing effect. When the material enters the shell through the feeding pipe, and then passes through the first filter piece and the second filter piece, and then enters the exhaust pipe and is discharged, because the arc-shaped pipe is screwed at the end of the exhaust pipe, a certain air flow resistance is given, so that the airflow can stay in the inside of the shell and the inside of the exhaust pipe for more time when being filtered, and the filtering purity is effectively improved.
