[0027] The following descriptions are based on Figure 1 The description is based on the orientation of the manual valve (1), that is, the manual valve (1) is located on the left side of the housing (2);

[0028] The working steps of the above embodiment are: first, the staff installs the present invention in the chemical pipeline, and then during the flow of the chemical liquid, the rear channel 2002 is first blocked by the baffle 4, so that the chemical liquid cannot flow from the rear channel 2002, so that the chemical liquid can only flow from the front channel 2002, and the impurities in the chemical liquid are filtered out by the front filter 3. After the present invention has been running for a period of time, when the front filter 3 filters out more impurities, the staff turns the knob 106 and all the parts connected to it in a counterclockwise direction from a top-down perspective. The knob 106 drives the left baffle 4 to rotate through the connecting rod 4001. When the left baffle 4 rotates to contact the inner front side of the shell 2, the baffle 4 cannot continue to rotate, and then the staff stops turning the knob 106; at the same time, since the gear III 105 is meshed with the rack 104, the rotation of the gear III 105 will push the rack 104 to move to the right; since the rack 104 is meshed with the rack The gear Ⅱ103 is meshed, so the rack 104 moves to the right to push the gear Ⅱ103 to rotate. Since the gear Ⅱ103 is meshed with the gear Ⅰ102, the gear Ⅱ103 will drive the gear Ⅰ102 to rotate after the gear Ⅱ103 rotates, so that the baffle 4 on the right rotates. When the baffle 4 on the right rotates to contact the inner front side of the shell 2, the baffle 4 on the right cannot continue to rotate. At this time, the two baffles 4 respectively block the left and right sides of the front channel 2002, so that the chemical liquid cannot continue to flow through the front channel 2002, and the baffle 4 no longer blocks the rear channel 2002, so that the chemical liquid starts to flow from the rear channel 2002; at this time, the baffle 4 cooperates with the shell 2, so that a relatively closed space is formed between the baffle 4 and the shell 2, thereby preventing the gas in the pipeline from entering the front channel 2002, and preventing the gas in the pipeline from flowing out from the filter 3 when the filter 3 is replaced, causing an impact on the staff.

[0029] Then the staff member pulls the front clamping plate 202 to move to the right again, so that the clamping plate 202 no longer clamps the front extraction block 3001, and the spring rod 203 is compressed. Then, when the clamping plate 202 moves to the right to the limit block 204, the clamping plate 202 squeezes the limit block 204, forcing the limit block 204 to rotate upward. Then, when the clamping plate 202 moves to the right to the right of the limit block 204, the clamping plate 202 no longer squeezes the limit block 204, and then the torsion spring connected to the limit block 204 drives the limit block 204 to move downward and reset, thereby limiting the clamping plate 202 through the limit block 204, avoiding the subsequent process of the staff pulling out the filter 3. The spring rod 203 resets and pushes the clamping plate 202 to move to the left, which affects the staff pulling out the filter 3, so that the staff does not need to keep pulling the clamping plate 202 when pulling out the filter 3.

[0030] When the clamping plate 202 is limited, the staff pulls the filter screen 3 upward by pulling out the block 3001. In the process of pulling out the filter screen 3, it is difficult to avoid the filter screen 3 from shaking, and the shaking of the filter screen 3 will cause the filtered impurities attached to the filter screen 3 to fall off, causing the impurities to fall into the channel 2002, and some of the impurities will fall to the left of the filter screen 3, so that when the channel 2002 is used later, the impurities in the channel 2002 will flow with the chemical liquid, causing damage to the chemical liquid. Therefore, the fallen impurities are caught by the rotating plate 301 to prevent the impurities from falling directly into the channel 2002, and then when the filter 3 drives the rotating plate 301 to move upward, since the upper end of the rotating plate 301 is provided with a magnetic metal strip, the rotating plate 301 is affected by the magnetic force of the magnetic plate 302, so that the rotating plate 301 rotates in the direction close to the filter 3, so that the filter 3 can be pulled out of the shell 2 normally, thereby preventing the rotating plate 301 from affecting the pulling out of the filter 3.

[0031] After the staff pulls out the filter 3, the staff cleans the filter 3, and then after the cleaning is completed, the staff reinserts the filter 3 into the shell 2, and then the staff presses the right end of the limit block 204 to force the limit block 204 to rotate upward, so that the limit block 204 no longer limits the clamping plate 202, and then the spring rod 203 pushes the clamping plate 202 to move to the left, so that the clamping plate 202 clamps the pulling block 3001 again, and then when the impurities filtered out by the rear filter 3 are more, the staff turns the knob 106 again to make the baffle 4 rotate to contact with the rear side surface of the shell 2, thereby cleaning the rear filter 3, and so on and so forth, thereby preventing the filter 3 from being blocked and facilitating the staff to replace it.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
