Detailed Implementation

[0018] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0019] Reference Figs. 1-3 A sliding cleaning and dispersing mechanism for a fly ash rotary dryer includes a dryer body 101, a rotating frame 102 rotatably mounted inside the dryer body 101, a plurality of heavy-duty dispersing mechanisms 200 inside the rotating frame 102, a sliding cleaning mechanism 400 mounted on the side wall of the dryer body 101, and a blowing mechanism 300 for cooperating with the sliding cleaning mechanism 400 on the side wall of the dryer body 101.

[0020] The heavy-duty dispersing mechanism 200 is used to evenly disperse the clumps of material adhering to the inner wall of the rotating frame 102, so that the material is more evenly crushed and dispersed during the drying process. The sliding cleaning mechanism 400 is used to push the material adhering to the discharge port 405, thereby clearing the blockage.

[0021] Reference Figs. 1-3 The heavy-duty disintegration mechanism 200 includes a mounting block 201, a connecting shaft 202, a limiting ring 203, and a chain 204. The mounting block 201 is provided with several evenly and symmetrically distributed on the inner wall of the rotating frame 102. The connecting shaft 202 is installed between the mounting blocks 201. The limiting ring 203 is installed in the middle position of the connecting shaft 202. The chain 204 is symmetrically slidably arranged on the connecting shaft 202.

[0022] The rotation of the rotating frame 102 can drive the mounting block 201 and the connecting shaft 202 to rotate, thereby enabling the chain 204 to slide on the connecting shaft 202. The chain 204 slides stably on the connecting shaft 202, thus producing a more uniform and continuous scattering effect. Furthermore, using the connecting shaft 202 as a support point can reduce the wear of the chain 204 caused by shaking, improve the durability of the chain 204, and at the same time, the stable sliding trajectory also helps to improve the overall operating efficiency of the equipment.

[0023] Reference Fig. 1 The sliding cleaning mechanism 400 includes a limiting frame 401, a conveying and unloading screw 402, a fixing frame 403, a conveying body 404, a discharge port 405, a feed port 406, a motor 407, a sliding plate 408, a support plate 409, rollers 410, and a limiting post 411. A sliding plate 408 is fixedly installed on the side wall of the dryer body 101. Several rollers 410 are symmetrically rotatably arranged at the lower end of the support plate 409, and the rollers 410 are slidably mounted on the sliding plate 408. A conveying body 404 is fixedly installed on the side wall of the dryer body 101, and a feed port is provided on the side wall of the conveying body 404 away from the dryer body 101. 406. A discharge port 405 is provided on the other side wall of the conveying body 404. A fixing frame 403 is fixedly installed on the side wall of the conveying body 404 away from the dryer body 101. A motor 407 and a limiting post 411 are fixedly installed on the support plate 409. A limiting frame 401 is fixedly installed on the fixing frame 403. The output end of the motor 407 passes through the limiting post 411, the limiting frame 401 and the side wall of the conveying body 404 and connects to the conveying and unloading screw 402. The conveying and unloading screw 402 is slidably arranged on the inner wall of the conveying body 404. A blowing mechanism 300 is provided above the discharge port 405 on the side wall of the dryer body 101.

[0024] The starting motor 407 drives the conveying and unloading screw 402 to rotate, which can drive the conveying and unloading screw 402 to break up and convey the material. When the material adheres to the discharge port 405, the sliding support plate 409 drives the conveying and unloading screw 402 to move and push against the blocked material, thus playing a role in clearing the blockage.

[0025] Reference Figs. 1-2 The blowing mechanism 300 includes an air cannon 301, a support frame 302, and an air outlet 303. The support frame 302 is fixedly installed on the side wall of the dryer body 101. The air cannon 301 is installed on the support frame 302. The output end of the air cannon 301 passes through the side wall of the dryer body 101 and the rotating frame 102 and connects to the air outlet 303. The air outlet 303 cooperates with the side wall of the conveying body 404 near the discharge port 405.

[0026] The air cannon 301 releases compressed air to generate a powerful shock wave to loosen and disperse the blocked material. This shock wave can penetrate the material layer and generate vibration and shear force inside the material, thereby destroying the structure of the agglomerate and loosening it. Therefore, by releasing compressed air to the side wall of the conveying body 404 through the air cannon 301, the hardened material blocked at the discharge port 405 can be cleared.

[0027] Working principle: Material enters the conveying body 404 through the inlet 406. The starting motor 407 drives the conveying and unloading screw 402 to rotate, which disperses and conveys the material. When material adheres to the outlet 405, the sliding support plate 409 moves the conveying and unloading screw 402, pushing against the clogged material and clearing the blockage. The material is then conveyed through the conveying body 404 to the rotating frame 102. The rotating frame 102 rotates, causing the mounting block 201 and connecting shaft 202 to rotate, thus allowing the chain 204 to slide on the connecting shaft 202. The stable sliding path of the upper part of the conveyor 404 results in a more uniform and continuous dispersing effect. Furthermore, using the connecting shaft 202 as a support point reduces wear on the chain 204 caused by swaying, improving its durability. The stable sliding trajectory also contributes to improved overall equipment operating efficiency. The air cannon 301 releases compressed air to generate a powerful shock wave that loosens and disperses clogged materials. This shock wave can penetrate the material layer and generate vibration and shear force within the material, thereby breaking down the agglomerated structure and loosening it. Therefore, releasing compressed air onto the side wall of the conveyor body 404 via the air cannon 301 can clear the clogged material at the discharge port 405.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
