DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with the accompanying drawings:

[0020] Example 1: Please refer to Figure 1-5 : In the present embodiment, a pneumatic rotary sootblower comprises a sootblower 1 and a straight pipe 4. The front face of the sootblower 1 is connected to the rear end face of the straight pipe 4. How to operate and use the sootblower 1 is already existing technology and will not be elaborated on in detail. The model is selected according to the use requirements. The front end of the inner wall of the straight pipe 4 is rotatably connected with a circular tube 5. The cylinder 5 is subjected to force to rotate in front of the inner wall of the straight pipe 4 through a sealed bearing. The upper and lower sides of the circular tube 5 are respectively connected to a fixed structure 2. The upper and lower sides of the circular tube 5 are respectively processed with a first opening 6 in front. The left and right sides of the sootblower 1 are respectively connected to a supporting structure 3. A handle 9 is fixedly connected to the top of the sootblower 1 for easy lifting of the sootblower 1.

[0021] The fixing structure 2 includes a bracket 201 and a first screw rod 202. The inner sides of the two brackets 201 are fixedly connected to the upper and lower sides of the circular tube 5 respectively. The outer wall circular mouth of the bracket 201 is threadedly connected to the outer wall of the first screw rod 202. The first screw rod 202 is subjected to force to rotate up and down through the bracket 201. The inner side of the outer wall of the first screw rod 202 is rotatably connected with a clamping plate 203. The inner side of the outer wall of the first screw rod 202 is subjected to force to rotate through the outer bearing of the clamping plate 203. A handle 204 is fixedly connected to the outer side of the first screw rod 202. The handle 204 is convenient for driving the first screw rod 202 to rotate. A vertical rod 205 is fixedly connected to the outer rear of the clamping plate 203. The outer wall of the vertical rod 205 is slidably engaged with the outer wall of the bracket 201. The vertical rod 205 is subjected to force to slide up and down through the outer wall of the bracket 201. The inner side of the clamping plate 203 is pressed against a sleeve 10. The inner wall of the sleeve 10 is plugged into the outer wall of the circular tube 5 at the rear.

[0022] By cooperating with the handle 204 in the fixed structure 2, the first screw 202 is rotated inwardly through the bracket 201, so that the clamp 203 moves inwardly, so that the inner side of the clamp 203 presses the outer wall of the sleeve 10, and the vertical rod 205 will also move with the movement of the clamp 203 to limit the clamp 203 and prevent it from rotating. Then the sleeve 10 is placed in the soot blowing position, eliminating the use limitations of the pneumatic rotary soot blower and ensuring the normal use of the pneumatic rotary soot blower.

[0023] A second opening 11 is respectively processed at the front of the upper and lower sides of the sleeve 10, and a baffle 7 is inserted in the front of the inner wall of the circular tube 5. Bolts 8 are respectively threaded on the upper and lower sides of the inner wall of the baffle 7. The bolts 8 fix the baffle 7. Before connecting the sleeve 10, the baffle 7 needs to be inserted to open the front of the circular tube 5. The outer wall end of the bolt 8 is threadedly connected to the inner wall of the circular tube 5. The supporting structure 3 includes a protruding rod 301 and a cylinder 302. The inner sides of the two protruding rods 301 are respectively fixed to the lower left and right sides of the soot blower 1. The bottom of the outer wall of the protruding rod 301 is inserted into the inner wall of the cylinder 302. The cylinder 302 is forced to move downward and can be separated from the bottom of the outer wall of the protruding rod 301. The bottom of the cylinder 302 is fixed with a bottom plate 303.

[0024] Working principle:

[0025] When the soot blower 1 is used, the inner wall of the sleeve 10 is first plugged into the outer wall of the circular tube 5 until the rear of the outer wall of the sleeve 10 is located on the inner side of the clamping plate 203, and then the handle 204 is used to drive the first screw 202 to rotate inward through the bracket 201, so that the clamping plate 203 moves inward, so that the inner side of the clamping plate 203 presses the outer wall of the sleeve 10, and the vertical rod 205 will also move during the movement of the clamping plate 203 to limit the clamping plate 203 and prevent it from rotating. Then the sleeve 10 is placed in the soot blowing position, and the soot blower 1 is started. The wind source enters the circular tube 5 through the straight pipe 4 and is finally discharged through the sleeve 10 at the second opening 11 to perform soot blowing. Since the second opening 11 and the inner wall of the first opening are both provided with inclined surfaces, when the wind source passes by, the circular tube 5 will be rotated to realize the start rotation. When soot blowing for a long time, the bottom of the bottom plate 303 can be fitted with the contact surface, thereby cooperating with the cylinder 302 and the convex rod 301 to support the soot blower 1.

[0026] Example 2: Please refer to Figure 1-5 In this embodiment, the support structure 3 also includes a second screw rod 3a1 and a curved rod 3a2. The outer wall of the second screw rod 3a1 is threadedly connected to the inner wall of the convex rod 301, the top of the second screw rod 3a1 is fixedly connected to the bottom of the curved rod 3a2, and the bottom of the second screw rod 3a1 is fixedly connected to the bottom of the inner wall of the cylinder 302.

[0027] Working principle:

[0028] The second screw rod 3a1 cooperates with the bent rod 3a2 to rotate downward through the protruding rod 301, and then rotates downward with the cylinder 302, so that the bottom plate 303 moves downward, and the height of the soot blower 1 is adjusted to meet the support requirements.
