[0017] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments: Figure 1-Figure 3 The baffle 3 structure of the boiler flue 2 cleaning device includes a sandblasting device, which is used to clean the residue on the boiler flue 2. The sandblasting device includes a nozzle 1, and the nozzle 1 is a conical nozzle 1. At the same time, in order to facilitate the adjustment of the sandblasting direction, a baffle 3 is arranged in the boiler flue 2, and the sandblasting direction and angle are achieved by changing the angle of the baffle 3.

[0018] However, the vertically reflected gravel may damage the nozzle 1 itself, and the baffle 3 itself moves or rotates. Therefore, a baffle 3 structure is proposed to prevent the nozzle 1 from being impacted.

[0019] The baffle 3 includes a movable groove 4, in which a plurality of movable blocks 5 are embedded. The movable blocks 5 are connected end to end with each other, wherein adjacent movable blocks 5 can move independently, and each movable block 5 is installed in the movable groove 4 and kept parallel to the baffle 3 at the same time. The movable blocks 5 are fixed and moved, so as to play the function of normal reflective sandblasting.

[0020] Furthermore, a guide rod 6 is connected to the rear side of the movement, and the guide rod 6 is slidably connected in the baffle 3. Specifically, a control board 7 is provided in the movable groove 4. The guide rod 6 is slid on the control board 7. The control board 7 realizes the movement control of the moving block 5, and at the same time, the integrity of the outer facade of the baffle 3 can be realized, so that the movable connection structure is conveniently connected thereto.

[0021] At the same time, in order to ensure that the moving block 5 can be locked, a placement plate 9 is arranged on the outer shell of the flue 2, and a first magnetic component is arranged in the placement plate 9, and a second magnetic component is arranged on the moving block 5 component. The magnetic components corresponding to the two have the same magnetic poles, which can achieve repulsion between the two. A limiting block 8 is arranged at the tail of the guide rod 6. Under the action of the limiting block 8, the moving block 5 and the baffle 3 can be kept flat. The second magnetic component can be arranged on the limiting block 8, and the two can maintain the same magnetic poles.

[0022] A plurality of groups of nozzles 1 are arranged on the flue 2 boiler on the opposite side. According to the diameter of the nozzle 1 body, a hollow area 13 is arranged on the placement plate 9, that is, the first magnetic part is not arranged in the hollow area 13, so that when the sandblasting contacts and reflects with the moving block 5, the arc of the sand reflected by the nozzle 1 can be reduced, thereby reducing the damage to the nozzle 1.

[0023] Furthermore, in order to increase the stability of the guide rod 6 during its sliding movement and the stable buffering effect of the gravel, a spring 10 is arranged between the guide rod 6 and the baffle 3. The spring 10 passes through the guide rod 6 and is connected between the moving block 5 and the control member, thereby effectively increasing the elasticity of the impact and further reducing the reflected gravel.

[0024] The baffle 3 is connected to the rod body 11, and the rod body 11 slides in the boiler flue 2. Since there are a large number of nozzles 1, the baffle 3 needs to be moved repeatedly to clean the flue 2 boiler. For this, the rod body 11 is the output shaft of the electric push rod 12, so the baffle 3 can move back and forth between each nozzle 1 to achieve sandblasting cleaning.

[0025] In order to protect the rod body 11, a flexible rubber protective cover can be wrapped around the outside of the rod body 11. At the same time, the rubber protective cover can further increase the sealing performance between the rod body 11 and the boiler flue 2 without hindering the sliding connection therebetween.

[0026] In summary, the sandblasting adjustment structure controls the sandblasting reflection by moving the baffle 3, that is, cleans the entire inside of the flue 2, and at the same time cooperates with the moving block 5, the guide rod 6, the spring 10, the rod body 11, the electric push rod 12, the first magnetic part and the second magnetic part to achieve the reflection of sand and gravel, and always avoid the main body of the nozzle 1, thereby increasing the service life of the main body of the nozzle 1.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents.
