[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0024] like Figures 1 to 8 As shown, the anti-shaft lock device of the incineration exhaust gas purification system of the present invention includes a pipe 1 for conveying smoke and dust. Both ends of the pipe 1 are provided with connecting portions 2 for connecting to other pipes 1, which can be fixed by bolts. The arrangement of the pipe 1 can control the conveyance and stopping of smoke and dust, acting as a switch. Furthermore, the adopted structure prevents the rotating shaft 3 from locking in high-temperature environments.

[0025] Pipe 1 has fixtures 4 on either side, one of which is attached to a driver 5, which can be a motor. Pipe 1 also has a rotating shaft 3 in the middle, with both ends attached to fixtures 4 and one end connected to driver 5. Rotating driver 5 drives shaft 3 as well.

[0026] A rotating member 6 is provided on the rotating shaft 3, and the rotating member 6 is connected to the rotating shaft 3 via a pin 8. A rotating portion 7 is provided in the middle of the rotating member 6. The middle of the rotating portion 7 is hollowed out, and the rotating shaft 3 can be inserted into it, and then fixed to the rotating member 6 via the pin 8, so that the rotating member 6 can rotate together with the rotating shaft 3.

[0027] Of course, the rotating member 6 is used to seal the pipe 1. When the rotating shaft 3 drives the rotating member 6 to rotate, so that the rotating member 6 and the fixed member 4 are in a perpendicular state, the rotating member 6 can now seal the pipe 1 and cut off the smoke and dust. In order to facilitate the rotation of the rotating member 6, arc portions 9 are provided at the upper and lower ends of the rotating member 6. The design of the arc surface 16 can make the arc portions 9 better contact with the inner wall of the pipe 1, and achieve linear contact between the arc portions 9 and the inner wall of the pipe 1. Only the rotating shaft 3 needs to drive the rotating member 6 to rotate, so that the upper and lower ends of the rotating member 6 block the smoke and dust, achieving a sealing effect.

[0028] In addition, a support member 10 is provided on the fixed member 4, and the support member 10 is used to support the rotating shaft 3. A rotating member 11, a blocking member 12 and a spring 13 are provided at both ends of the rotating shaft 3. The blocking member 12 is in contact with the outer wall of the pipe 1, and one end of the spring 13 is in contact with the blocking member 12, and the other end is in contact with the rotating member 11. The lower end of the rotating member 11 is in contact with the support member 10, and the fixed member 4 is provided with a symmetrically arranged limit seat 14, and the limit seat 14 is connected to the upper end of the rotating member 11 through an elastic member 15. The support member 10 is arc-shaped and has a downward recess 101 in the middle. When the rotating member 11 is placed in the recess, the position of the rotating member 11 can be limited by the recess, so that the rotating member 11 can only rotate therein, and cannot move left or right, that is, it cannot move in the axial direction of the rotating shaft 3.

[0029] Furthermore, the rotating member 11 has an arcuate surface 16 and a vertical surface 17. The vertical surfaces 17 are located on either side of the arcuate surface 16. The spring 13 contacts one of the vertical surfaces 17, and the other vertical surface 17 is provided with multiple recessed holes 18. A ball 19 is located in each recessed hole 18, and the ball 19 contacts the fixed member 4. When installing the ball 19, the ball 19 is first installed in the recessed hole 18, and then the ball 19 contacts the fixed member 4. Furthermore, the rotating member 11 is provided with multiple mounting grooves 20, which are spaced apart from the recessed holes 18. A baffle 21 is provided on the rotating shaft 3 and is installed in the mounting grooves 20. The rotating member 11 also has an axial hole 22 in the center for the rotating shaft 3 to be inserted therein, and the baffle 21 is inserted into the mounting grooves 20. When the rotating shaft 3 rotates, it drives the baffle 21 to rotate together, causing the baffle 21 to rotate the rotating member 11.

[0030] In addition, an annular groove 23 is provided on the arcuate surface 16. The elastic member 15 consists of a bent end portion 24, an elastic portion 25, and a contact portion 26 positioned in the annular groove 23. The stopper 14 is provided with a mounting hole 27, in which the end portion 24 is positioned. When installing the elastic member 15, one end of the elastic member 15 is first inserted into the mounting hole 27 on one side, and then the contact portion 26 is positioned in the annular groove 23. The other end of the elastic member 15 is then pulled forcefully, causing the other end to deform under force and enter the mounting hole 27 at the other end. The arrangement of the elastic member 15 and the support member 10 allows the rotating member 11 to be restrained on the rotating shaft 3. Even if the temperature in the middle of the rotating shaft 3 is too high, transferring the high temperature to both ends, causing the ends of the rotating shaft 3 to expand due to the heat, the rotating member 11 can continue to rotate on the support member 10 without locking.

[0031] A through hole 28 is provided in the middle of the fixing member 4 , and the rotating shaft 3 is disposed in the through hole 28 . The diameter of the through hole 28 is larger than the diameter of the rotating shaft 3 .

[0032] During installation, first place the rotating member 6 into the pipe 1, then insert the rotating shaft 3 through the pipe 1 and secure it with the pin 8. Next, weld the blocking member 12 to the rotating shaft 3, insert the spring 13, and weld the baffle 21 to the rotating shaft 3. During welding of the baffle 21, the spring 13 is in its natural position. Next, install the rotating member 11, the fixing member 4, and finally the elastic member 15. Finally, connect one end of the rotating shaft 3 to the driving member 5.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
