[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the attached drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.
[0022] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.
[0023] Such as Figures 1-6As shown, a purification device for waste gas treatment that is easy to clean includes a temporary storage box 1 and a filter box 2 fixedly arranged on the upper side of the temporary storage box 1, and also includes an intermittent back-blowing anti-clogging component 20 arranged in the temporary storage box 1, the intermittent back-blowing anti-clogging component 20 includes a turntable 8 rotatably arranged on the top inner wall of the temporary storage box 1, a linkage rod 9 eccentrically rotatably arranged on the turntable 8 at one end, a guide rail 21 opened on the top inner wall of the temporary storage box 1, and a control baffle 10 horizontally slidably arranged in the guide rail 21, wherein the control baffle 10 is provided with a guide A filter through hole 13 and an anti-clogging backblowing through hole 12 are provided on the top wall of the temporary storage box 1. The guide hole 11 corresponds to the filter through hole 13 and the anti-clogging backblowing through hole 12. The free end of the linkage rod 9 is rotatably connected to the control baffle 10. A ventilation pipe 18 is provided between the temporary storage box 1 and the filter box 2. An anti-clogging backblowing pipe 19 is provided between the temporary storage box 1 and the filter box 2. The ventilation pipe 18 corresponds to the filter through hole 13, and the anti-clogging backblowing pipe 19 corresponds to the anti-clogging backblowing through hole 12.
[0024] The filter box 2 is provided with a detachable filter screen plate 14 , and the connection between the anti-clogging backflush pipe 19 and the filter box 2 and the connection between the ventilation pipe 18 and the filter box 2 are respectively arranged on both sides of the filter screen plate 14 .
[0025] A connecting frame 15 is fixedly provided on the control baffle 10 , and a blocking plate 16 is fixedly provided on the connecting frame 15 .
[0026] An air outlet 17 is provided on the top wall of the filter box 2 , and the air outlet 17 corresponds to the blocking plate 16 .
[0027] An air monitor 6 is provided in the temporary storage box 1 , and a switch door 3 is provided on the side wall of the temporary storage box 1 .
[0028] An air inlet 5 is provided at one side of the temporary storage box 1 , and a negative pressure fan 4 is rotatably provided in the air inlet 5 .
[0029] A servo motor 7 is fixedly disposed on the top outer wall of the temporary storage box 1 , and an output end of the servo motor 7 is fixedly connected to the central axis of a turntable 8 .
[0030] During specific use, first turn on the negative pressure fan 4 and the servo motor 7. The negative pressure fan 4 sucks the waste gas into the temporary storage box 1. The servo motor 7 drives the turntable 8 to rotate. The turntable 8 drives the linkage rod 9 to move. The linkage rod 9 drives the control baffle 10 to move horizontally back and forth. When the diversion hole 11 corresponds to the filtering through hole 13, at this time, the waste gas will enter the filtering box 2 from the diversion hole 11 and the ventilation pipe 18. At this time, the blocking plate 16 no longer blocks the air outlet hole 17. Therefore, the waste gas will be filtered through the filter mesh plate 14 and finally the filtered air will be discharged from the air outlet hole 17. When the diversion hole 11 corresponds to the anti-blocking back-blowing through hole 12, at this time, the blocking plate 16 blocks the air outlet hole 17, and the air will blow back through the filter mesh plate 14, so as to realize the cleaning effect on the dust or other particulate impurities on the front side of the filter mesh plate 14 and avoid the blockage of the filter mesh plate 14. This device can greatly reduce the cleaning and maintenance frequency of the filter mesh plate 14, thereby improving the use experience of the staff. When there are more impurities attached to both sides of the filter mesh plate 14, the filter mesh plate 14 can be taken out and cleaned.
[0031] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents. All in all, if those of ordinary skill in the art are inspired by it and design similar structural modes and embodiments without creative efforts without departing from the purpose of the present invention, they shall fall within the protection scope of the present invention.
