[0021] When the pre-filter device performs filtering work, first extend the external connecting air pipe to the inside of the air inlet pipe 2, then use the air bag air collecting device 4 on the outside of the pipe sleeve 15 to output air to the inside of the expansion air bag 5, so that the air is collected and expanded, thereby squeezing and clamping the external pipe connected to the inside of the air inlet pipe 2, thereby facilitating the connection between the external pipe and the air inlet pipe 2. After the connection is completed, the exhaust gas enters the interior of the shell 1 through the air inlet pipe 2, and the particulate matter, stains and other trace elements in the exhaust gas are filtered through the filter plate 9 made of activated carbon. During the filtering process, the lifting component is used The movable plate 11 is driven to move up and down, so that the brush 14 on one side of the movable plate 11 cleans the dirt on the filter plate 9. The scraped dirt will fall into the sewage hopper 7 under the influence of gravity, and finally the filtered gas is discharged through the blower 3. After completing the RTO organic waste gas treatment, the dirt inside the sewage hopper 7 is discharged centrally through the sewage valve 8. Thus, the filter plate 9 is continuously cleaned by the brush 14, which effectively avoids the accumulation of dirt on the filter plate 9, so that the pre-filtering device can effectively complete the pre-filtration of the waste gas, thereby improving the waste gas treatment efficiency.

[0022] like Figure 1 and Figure 4As shown, the lifting assembly includes a threaded rod 12, which is rotatably connected between the inner walls of the shell 1, the outer side of the threaded rod 12 is threadedly connected to the movable plate 11, one side of the movable plate 11 is fixedly connected with a brush 14, the outer side of the brush 14 is in contact with the filter plate 9, a servo motor 6 is fixedly installed on the top of the shell 1, the output end of the servo motor 6 extends to the interior of the shell 1 and is fixedly connected to the threaded rod 12, one side of the movable plate 11 is fixedly connected with a limiting block 13, a limiting groove 10 is provided on the inner side of the shell 1, and the outer side of the limiting block 13 is slidably connected to the inner wall of the limiting groove 10.

[0023] The threaded rod 12 is driven by the servo motor 6 to rotate between the inner walls of the shell 1, so that the movable plate 11 is driven to slide between the inner walls of the shell 1 under the cooperation of the limit block 13 and the limit groove 10, and at the same time, the brush 14 is driven to contact the filter plate 9, so that the dirt on the outside of the filter plate 9 is removed, thereby facilitating the timely cleaning of the filter plate 9 to avoid dirt accumulation and clogging of the filter plate 9.

[0024] The utility model provides a pre-filter device suitable for RTO organic waste gas treatment equipment, and the specific working principle is as follows: when the pre-filter device performs filtering work, the external connecting air pipe is first extended to the inside of the air inlet pipe 2, and then the air bag air collecting device 4 on the outside of the pipe sleeve 15 is used to output air to the inside of the expansion air bag 5 to make the air collection expand, thereby squeezing and clamping the external pipe connected to the inside of the air inlet pipe 2, thereby facilitating the connection of the external pipe with the air inlet pipe 2. After the connection is completed, the exhaust gas enters the interior of the shell 1 through the air inlet pipe 2, and the exhaust gas is filtered out by the filter plate 9 made of activated carbon. The particles, stains and other trace elements in the air are filtered. During the filtering process, the servo motor 6 is used to drive the threaded rod 12 to rotate between the inner walls of the shell 1, so that the movable plate 11 is driven to slide between the inner walls of the shell 1 under the cooperation of the limit block 13 and the limit groove 10, so that the brush 14 on one side of the movable plate 11 cleans the dirt on the filter plate 9. The scraped dirt will fall into the sewage hopper 7 under the influence of gravity. Finally, the filtered gas is discharged through the blower 3. After completing the RTO organic waste gas treatment, the dirt inside the sewage hopper 7 is discharged centrally through the sewage valve 8.
