[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying 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.

[0022] Referring to Figures 1-4 , an exhaust gas environmental protection treatment device includes a spray tower 1. An extension pipe 2 is connected to the front of the spray tower 1, and an observation port 3 is installed on the front of the extension pipe 2. A support column 4 is provided on the side of the extension pipe 2, and a rotating block 5 is sleeved outside the support column 4. Two rectangular grooves 7 are opened inside the rotating block 5, and moving plates 9 are inserted into the rectangular grooves 7. A limiting rod 10 is connected to the side of the moving plates 9 close to each other, and the limiting rod 10 extends into the support column 4. Springs 8 are connected to the sides of the moving plates 9 away from each other, and the other ends of the springs 8 are connected to the inner walls of the rectangular grooves 7. A protection plate 13 is connected to the side of the rotating block 5.

[0023] Further, referring to Figure 4 , it can be known that an annular groove is opened inside the rotating block 5, and a connecting ring 6 is inserted into the annular groove. The connecting ring 6 is sleeved outside the support column 4. During use, through the mutual cooperation of the annular groove and the connecting ring 6, the guiding of the rotating block 5 can be realized, and while not affecting the rotation of the rotating block 5, the situation that the rotating block 5 moves forward and backward can be prevented.

[0024] Further, referring to Figure 4 , it can be known that a linkage block 12 is connected to the upper side of the moving plate 9, and the linkage block 12 is set as a spherical structure. During use, through the spherical structure of the linkage block 12, it is convenient for the staff to quickly pull the moving plate 9, thereby effectively improving the convenience during the use of this device.

[0025] Further, referring to Figure 4 , it can be known that cross bars 11 are symmetrically connected to the upper and lower ends of the rectangular groove 7, and moving grooves adapted to the cross bars 11 are opened inside the moving plate 9. During use, through the mutual cooperation of the moving grooves and the cross bars 11, the guiding of the moving plate 9 can be realized to ensure the stable movement of the moving plate 9 inside the rectangular groove 7.

[0026] Further, referring to Figure 3 , it can be known that an insertion slot is opened on the back of the support column 4, and a docking rod 17 is inserted into the insertion slot. The back of the docking rod 17 is connected to the outer wall of the spray tower 1, and the side of the support column 4 is connected to the docking rod 17 through bolts. During use, through the mutual cooperation of the docking rod 17 and the bolts, the disassembly operation of the support column 4 and the protection plate 13 can be realized, so that the staff can replace the damaged protection plate 13 in time.

[0027] Further, referring toFigure 3 It can be known that a groove is provided at the center position on the back surface of the protection plate 13, and a scraping strip 16 is glued to the inner wall of the groove. During the process of the staff rotating the protection plate 13, the scraping strip 16 arranged on the inner side of the protection plate 13 is forced to slide along the outer surface of the observation port 3. Since the scraping strip 16 is made of rubber material, the sundries attached to the observation port 3 can be scraped off, so as to clean the sundries on the front surface of the observation port 3.

[0028] Further, referring to Figure 2 and Figure 3 It can be known that rubber columns 15 are equidistantly connected to the front surface of the protection plate 13, and the other ends of the rubber columns 15 are connected with a protection pad 14. The longitudinal section of the protection pad 14 is set as a U-shaped structure. During use, through the protection pad 14 set in the U-shaped structure, the front surface and the edge of the protection plate 13 can be protected. Since the protection pad 14 is made of rubber material, the preliminary protection of the front surface of the protection plate 13 can be realized. With multiple groups of rubber columns 15 connected between the protection plate 13 and the protection pad 14, the impact force can be dispersed again to further improve the protection effect on the protection plate 13.

[0029] Working principle: When the present utility model is in use, the staff can first install the device at a suitable position. Through the mutual cooperation of each component inside the spray tower 1, the environmental protection treatment of the laboratory tail gas can be realized. During the treatment process, when the staff needs to check the working conditions inside the spray tower 1, the staff can first pull two linkage blocks 12 in the horizontal direction, so as to drive the two moving plates 9 connected to the bottom ends thereof to move away from each other. At this time, the limiting rods 10 connected to the sides of the moving plates 9 are drawn out from the inside of the support columns 4 to release the limitation on the support columns 4. Then the staff can rotate the protection plate 13, so that the rotating blocks 5 are simultaneously forced to rotate. When the protection plate 13 is rotated 180 degrees, the staff can stop pulling the linkage blocks 12, so that the limiting rods 10 are forced to be embedded into the support columns 4 again to realize the limitation on the rotating blocks 5 and the protection plate 13 again. At this time, the protection plate 13 no longer covers the observation port 3, so the staff can observe the situation inside the spray tower 1 through the observation port 3. After the observation is completed, the staff can pull the limiting rods 10 again, so that the protection plate 13 covers the observation port 3 again to realize the protection of the observation port 3. The above is the whole working principle of the present utility model.

[0030] In the present utility model, the installation methods, connection methods or setting methods of all the above-mentioned components are common mechanical methods, and the specific structures, models and coefficient indexes of all its components are its own technologies. As long as the beneficial effects can be achieved, they can be implemented, so no more details will be described.
