[0024] In one embodiment, Figure 1-Figure 5 As shown, a ash dumping prevention device for pneumatic conveying includes a self-operated air supply valve 101, an air supply branch pipe 102 is provided on one side of the self-operated air supply valve 101, an ash conveying pipeline 103 is provided on the side of the air supply branch pipe 102 away from the self-operated air supply valve 101, a mounting block 104 is provided on the side of the air supply branch pipe 102, a docking component is provided inside the mounting block 104, a snap-on component is provided inside the docking component, an unlocking component matched with the snap-on component is symmetrically provided inside the mounting block 104, the docking component and the snap-on component are used to cooperate with each other, so as to facilitate the installation of the filter 105 inside the mounting block 104, so as to filter the dirty air, and the unlocking component is provided to facilitate the unlocking of the snap-on component, so as to facilitate the disassembly of the filter 105 for replacement or cleaning.

[0025] In one embodiment, Figure 1 and Figure 4 As shown, the docking assembly includes a docking groove 201 and a docking block 202. The mounting block 104 is provided with a docking groove 201 inside, and one end of the docking block 202 is slidably arranged inside the docking groove 201. The docking block 202 is provided with a snap-on assembly on one side close to the inner wall of the mounting block 104. The docking block 202 is aligned with the docking groove 201 and pressed to install the docking block 202 on the mounting block 104, so that it is convenient to install the filter 105 inside the mounting block 104, thereby facilitating the filtering of the dirty air.

[0026] In one embodiment, Figure 4As shown, the snap-on assembly includes a snap-on block 301 and a first spring 302. The snap-on block 301 is symmetrically slidably provided on one side of the docking block 202 close to the inner wall of the mounting block 104, driving the two ends of the first spring 302 to connect the inner wall of the mounting block 104 and the side of the snap-on block 301 respectively. The inner wall of the docking groove 201 is provided with a snap-on groove that matches the snap-on block 301. The docking block 202 is aligned with the docking groove 201 and pressed. At this time, the snap-on block 301 is subjected to force to drive the first spring 302 to retract.

The pushing plate 503 cooperates with the clamping block 301. The two ends of the second spring 504 are respectively connected to the side surface of the pushing block 501 and the inner wall of the mounting block 104. The unlocking block 402 pushes the pushing block 501 to move in the direction of the clamping block 301. The pushing block 501 drives the connecting rod 502 and the pushing plate 503 to move in the opposite direction of the clamping block 301. The pushing plate 503 pushes the clamping block 301 to complete the unlocking. The second spring 504 is used to drive the pushing block 501 to reset, thereby facilitating the next unlocking movement.
