The bottom of the tower body 2 is fixedly connected to the left side of the top of the base plate 1, the bottom of the motor 3 is fixedly connected to the top of the tower body 2, the connecting frame 4 is located inside the tower body 2, the output end of the motor 3 passes through the top of the inner wall of the tower body 2 and is fixedly connected to the top of the connecting frame 4, the bottom of the circulating spray device 5 is fixedly connected to the right side of the top of the base plate 1, and the input of the circulating spray device 5 The end is connected to the right side of the top of the tower body 2 through a conduit, and the input end of the circulating spray device 5 is connected to the bottom of the right side of the tower body 2 through a conduit. A trapezoidal groove 7 is provided on the left side of the connecting frame 4, and a trapezoidal block 8 is slidably connected to the inner wall of the trapezoidal groove 7. The right side of the triangular scraper 6 is fixedly connected to the left side of the trapezoidal block 8, and the left side of the triangular scraper 6 is in contact with the inner wall of the tower body 2. An opening and closing component 9 is provided on the left side of the top of the tower body 2, a fixing mechanism 10 is provided inside the connecting frame 4, and an unlocking mechanism 11 is provided on the left side of the top of the front of the connecting frame 4.

[0024] refer to Figure 1 and Figure 3 The opening and closing component 9 includes a through slot 91, which is opened on the left side of the top of the tower body 2. Both sides of the inner wall of the through slot 91 are movably connected with a movable plate 92, and the outer side of the top of the movable plate 92 is movably connected to the two sides of the top of the tower body 2 through a hinge.

[0025] As a technical optimization solution of the present invention, by setting an opening and closing component 9, when the user needs to connect the triangular scraper 6 to the connecting frame 4, the movable plate 92 is pulled to make the movable plate 92 rotate symmetrically until the through slot 91 is opened, and then an open port is provided for the tower body 2 through the through slot 91. Then, the triangular scraper 6 can be placed into the tower body 2 through this open port, and the connection between the trapezoidal block 8 and the trapezoidal slot 7 can be controlled, thereby improving the user's operation convenience.

[0026] refer to Figure 3 and Figure 4 The fixing mechanism 10 includes a base groove 101, which is opened inside the connecting frame 4. The inner wall of the base groove 101 is connected to the inner wall of the trapezoidal groove 7. A connecting groove 102 is opened on the top of the right side of the trapezoidal block 8. The inner wall of the base groove 101 is slidably connected with a fixing block 103. The left side of the surface of the fixing block 103 is slidably connected to the inner wall of the connecting groove 102. The right side of the fixing block 103 is fixedly connected with a spring 104, and the other end of the spring 104 is fixedly connected to the right side of the inner wall of the base groove 101.

[0027] As a technical optimization solution of the present invention, by setting a fixing mechanism 10, when the user holds the triangular scraper 6 and controls the trapezoidal block 8 to insert into the trapezoidal groove 7, the inclined surface of the fixing block 103 first contacts the trapezoidal block 8, and is then squeezed by the trapezoidal block 8, gradually shrinking into the base groove 101, and squeezing the spring 104, causing the spring 104 to deform and generate a rebound force. Subsequently, when the trapezoidal block 8 is fully inserted into the trapezoidal groove 7 and the connecting groove 102 coincides with the base groove 101, the rebound force of the spring 104 is released, pushing part of the fixing block 103 into the connecting groove 102, thereby limiting and fixing the trapezoidal groove 7 and the trapezoidal block 8, thereby stabilizing the connection between the triangular scraper 6 and the connecting frame 4.

[0028] refer to Figure 4 The unlocking mechanism 11 includes an unlocking slot 111, which is opened on the left side of the top front of the connecting frame 4. The unlocking slot 111 is connected to the base slot 101. The inner wall of the unlocking slot 111 is slidably connected with an extension rod 112. The back of the extension rod 112 is fixedly connected to the front of the fixed block 103. The right side of the top front of the connecting frame 4 is movably connected with an L-shaped rod 113 through an axle pin.

[0029] As a technical optimization solution of the present invention, by setting an unlocking mechanism 11, when the triangular scraper 6 has been used for a long time and is excessively worn and needs to be replaced, the user pulls the extension rod 112 to move along the track of the unlocking groove 111, so that the part of the fixed block 103 inserted into the connecting groove 102 gradually shrinks into the base groove 101 and squeezes the spring 104 again. Then, when the fixed block 103 is completely pulled out of the connecting groove 102, the L-shaped rod 113 is rotated to hook the extension rod 112, blocking the release of the rebound force of the spring 104, thereby canceling the limiting fixation of the fixed block 103 on the trapezoidal groove 7 and the trapezoidal block 8, and then the triangular scraper 6 can be pulled apart from the connecting frame 4, and the triangular scraper 6 can be replaced, thereby improving the stability of the cleaning effect when using the triangular scraper 6 to clean the inner wall of the tower body 2.

[0030] refer to Figure 2 The front and back sides of the triangular scraper 6 are fixedly connected with power rods 12, and a plurality of power rods 12 are provided and distributed at equal distances.

[0031] As a technical optimization solution of the present invention, by setting a power-assisting rod 12, when the user pulls the triangular scraper 6 out of the tower body 2, the power-assisting rod 12 is used to provide multi-level grabbing points for the triangular scraper 6, which is convenient for the user to grab and lift the triangular scraper 6 alternately step by step, thereby preventing the triangular scraper 6 from being too long for the user to lift, and ultimately improving the user's operation convenience.

[0032] refer to Figure 3 The surface of the movable plate 92 is fixedly connected to a rubber pad 13 , and the surface of the rubber pad 13 is movably connected to the inner wall of the through groove 91 .

[0033] As a technical optimization solution of the present invention, by providing a rubber pad 13, when the flap 92 and the through groove 91 are closed, the rubber pad 13 is squeezed and deformed, thereby increasing the contact area between the flap 92 and the through groove 91, thereby reducing the gap at the closed position, improving the sealing, and preventing the exhaust gas from overflowing from the gap when entering the tower body 2.

[0034] refer to Figure 1 A transparent observation window 14 is fixedly embedded on the front of the tower body 2.

[0035] As a technical optimization solution of the present invention, a transparent observation window 14 is provided. When the motor 3 drives the connecting frame 4 to rotate the triangular scraper 6 to scrape and clean the inner wall of the tower body 2, the transparent observation window 14 is scraped together. Then, the transparent observation window 14 is used to observe the scraping condition of the triangular scraper 6 on the inner wall of the tower body 2, so as to judge the degree of wear of the triangular scraper 6, and finally facilitate the user to judge whether the triangular scraper 6 needs to be replaced.

[0036] The working principle and use process of the present invention are as follows: when the exhaust gas is input into the tower body 2, the circulating spray device is started to circulate and spray the exhaust gas. When the treatment is completed, the inner wall of the tower body 2 needs to be scraped and cleaned, and the movable plate 92 is pulled to rotate the movable plate 92 symmetrically until the through slot 91 is opened, and an opening is provided for the tower body 2 through the through slot 91. Then, the triangular scraper 6 is held, and the trapezoidal block 8 is aligned with the trapezoidal slot 7 on the connecting frame 4 and inserted. Then, as the trapezoidal block 8 is advanced, the inclined surface of the fixed block 103 first contacts the trapezoidal block 8 and is squeezed by the trapezoidal block 8, gradually shrinking into the base groove 101, and at the same time squeezing the spring 104 to deform it and generate a rebound force. Subsequently, when the trapezoidal block 8 is fully inserted into the trapezoidal groove 7 and the connecting groove 102 coincides with the base groove 101, the rebound force of the spring 104 is released, pushing part of the fixed block 103 into the connecting groove 102, thereby When the cam 114 is in the closed position, the cam 114 is in the closed position, and the cam 114 is in the closed position, so that the cam 114 is in the closed position and the cam 114 is in the closed position, and the cam 114 is in the closed position, so that the cam 114 is in the closed position, and the cam 114 is in the closed position, so that the cam 114 is in the closed position, and the cam 114 is in the closed position, so that the cam 114 is in the closed position, and the cam 114 is in the closed position, so that the cam 114 is in the closed position, and the cam 114 is in the closed position, so that the cam 114 is in the closed position, and the cam 114 is in the closed position, so that the cam 114 is in the closed position, and the cam 114 is in the closed position, so that the cam 114 is in the closed position, and the cam 114 is in the closed position,

[0037] To sum up: the waste gas spray tower for waste gas treatment is equipped with trapezoidal blocks 8 and trapezoidal grooves 7. When the triangular scraper 6 is needed to scrape and clean the inner wall of the tower body 2, the user holds the triangular scraper 6, aligns the trapezoidal block 8 with the trapezoidal groove 7 on the connecting frame 4, and then inserts it to connect the triangular scraper 6 to the connecting frame 4, and then starts the motor 3 to drive the connecting frame 4 to drive the triangular scraper 6 to rotate, which solves the problem that the scraper will gradually wear out when cleaning the inner wall of the tower body, and will suffer excessive wear after long-term use, thereby reducing the contact area with the inner wall and reducing the cleaning effect on the inner wall of the tower body. However, the scraper and the connecting frame are welded and fixed, which is not easy to replace.
