[0044] In other embodiments, a discharge pipe may be further provided at the bottom end of the air intake pipe 6 to discharge the impurities cleaned by the cleaning plate 38 out of the air intake pipe 6;

[0045] Among them, a plurality of flow-catching blades are fixedly connected to the outer side of the flow-catching roller 40, and the flow-catching blades are of an arc-shaped structure. By utilizing the setting of the flow-catching blades, when air flows through the flow-catching roller 40, the flow-catching blades can be blown, thereby driving the flow-catching shaft 39 to rotate.

[0046] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0047] Working principle: First, the air inlet pipe 6 is connected to the air supply pipe of the clean room, and the exhaust pipe 7 is connected to the circulation pipe of the clean room. When the airflow in the clean room enters the air inlet pipe 6, the filter 30 can be used to perform preliminary treatment on the airflow entering;

[0048] The flow space inside the air supply main pipe 1 is cut off by the blocking disk 13, so that the airflow can only be transmitted through the multiple filter branches 5 in sequence. When the airflow enters the filter branch 5, the purification filter element body 27 can be used to filter out impurities in the airflow. Finally, the airflow treated by the purification filter element body 27 will be sent to the circulation pipeline of the clean room through the exhaust pipe 7 and return to the inside of the clean room.

[0049] In the process of connecting the filter branch pipe 5 and the load-bearing arc plate 9, the push plate 26 will first contact the force-bearing slide bar 23. When the filter branch pipe 5 is displaced later, the push plate 26 can be used to push the force-bearing slide bar 23, thereby driving the blocking piece 24 to move, thereby releasing the blockage of the shunt pipe 3 and squeezing the coil spring 25 at the same time.

[0050] When the application effect of a purification filter element main body 27 at a certain place is not good, the transmission screw 19 at the corresponding purification filter element main body 27 is rotated, and the transmission screw 19 and the linear slide rod 20 are set, which can drive the displacement seat 21 to move linearly under the limit of the linear slide rod 20, and push the eccentric transmission plate 16. Since the eccentric transmission plate 16 is supported by the central shaft rod 12, it can drive the central shaft rod 12 to rotate, prompting the blocking disk 13 to release the blockage of the air supply main pipe 1, and cooperate with the connection between the central shaft rod 12 and the guide plate 14, so that the guide plate 14 can rotate with the central shaft rod 12, and pull the linkage frame 11 through the linkage rod 15, thereby driving The positioning arc plate 10 is flipped upward to release the positioning of the filter branch pipe 5, and then the filter branch pipe 5 is pulled outward to remove the filter branch pipe 5 from the bearing arc plate 9, so that the deduction plate 26 is separated from the contact with the force-bearing slide rod 23, and the plugging piece 24 is pushed to move by the spiral spring 25, so that the plugging piece 24 forms a blockage of the shunt pipe 3 to prevent the gas in the gas supply main pipe 1 from being discharged from the shunt pipe 3 that is not connected to the filter branch pipe 5. After the filter branch pipe 5 is removed, the plugging plate 13 can release the blockage of the gas supply main pipe 1, so that a complete passage can still be formed between other filter branch pipes 5, so that the filter branch pipe 5 can be removed and replaced without stopping the machine;

[0051] Before the replacement step of the filter branch pipe 5, the guide shaft 33 is rotated to cause the guide worm 34 to turn the matching worm wheel 35, so as to drive the flow control shaft 31 to rotate, and the flow control shaft 31 and the blocking plate 32 are connected, so that the blocking plate 32 can gradually block the flow control slot 29, and adjust the flow of the gas from the intake pipe 6 into the gas supply main pipe 1, so as not to increase the purification strength of other filter branches 5;

[0052] The limit screw 43 is rotated regularly, and the connection between the limit screw 43 and the limit cylinder 42 is coordinated to make the stop plate 44 disengage from the connection with the flow-catching shaft 39, release the limit on the flow-catching shaft 39, and allow the flow-catching shaft 39 to rotate. When the air flow flows inside the intake pipe 6, the flow-catching roller 40 can be pushed to cause the flow-catching shaft 39 to rotate, and under the connection of the two linked bevel gears 41, the cleaning shaft 37 is caused to rotate, so that the cleaning plate 38 wipes the filter screen 30 and brushes off the particles attached to its surface, thereby cleaning the filter screen 30 and ensuring the application effect of the filter screen 30.

[0054] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
