[0002] A single bin pump is one of the main devices in dense phase pneumatic ash conveying, and is used in a fluidized ash conveying system. It uses compressed air as power to transport powdery materials through a conveying pipe to an ash silo or a storage bin, and is suitable for the conveying of powdery materials such as fly ash, bottom slag, limestone powder, and cement in power plants. The bottom end of the single bin pump is a gasification bin, a fluidization plate is fixed between the gasification bin and the single bin pump, and the inside of the gasification bin is a gasification chamber.

[0003] The patent specification with the publication number CN214140601U discloses a fixing structure for the bottom bin of a pneumatic ash conveying single bin pump. The gasification bin flange and the bottom flange of the bin are fixed by extrusion and clamping through a C-shaped clamping plate and a large-headed screw, avoiding the conventional multi-bolt penetration and extrusion fixation, making the installation and fixation between the gasification bin flange and the bottom flange of the bin faster and more convenient. At the same time, it is also convenient for the disassembly, maintenance, and cleaning of the ash conveying gasification bin, etc., with stronger practicability. Moreover, this fixing method also avoids operations such as opening holes in the gasification bin gasket, improving the integrity of the gasification bin gasket.

[0004] However, it is found in the implementation of the related technology that the above technical solution has the following problems: In the process of using the above device, the gasification bin flange and the bottom flange of the bin are fixed by extrusion and clamping through a C-shaped clamping plate and a large-headed screw, avoiding the conventional multi-bolt penetration and extrusion fixation, making the installation and fixation between the gasification bin flange and the bottom flange of the bin faster and more convenient. However, due to the vibration generated during the daily work of the device, the fixing structure of the gasification bin of the device gradually falls off from the clamping plate seat after long-term vibration, resulting in the damage of the device. Therefore, further improvement is needed. Summary of the Utility Model

A circular groove 3231 is formed through one side of the first clamping block 323. A second through groove 3221 is formed through the upper end of the ring block 322. The second through groove 3221 passes through the inside of the second fixing ring 32 and is connected to the outside. The second through groove 3221 is connected to the first through groove 311. The circular groove 3231 passes through the inside of the ring block 322 and the second clamping block 324 and is connected to the outside. The circular groove 3231 is connected to the thread groove 3141. The anti-overflow soft pads 321 are used to reduce the gap at the connection between the first fixing ring 31 and the second fixing ring 32, thereby preventing the overflow of water and liquid.

[0032] As Figure 5 and Figure 6As shown, a threaded rod 33 and a threaded shaft 34 are disposed through the interiors of the first fixing ring 31 and the second fixing ring 32. A threaded cap 331 is disposed on one side of the threaded rod 33.

At this time, under the action of the first clamping block 323 and the second clamping block 324, the ring block 322 can be prevented from rotating inside the ring groove 312. At this time, the threaded shaft 34 can be passed through the interior of the circular slot 3231 and threadedly connected to the threaded groove 3141. At this time, under the action of the threaded shaft 34, the first fixing ring 31 and the second fixing ring 32 can be initially fixedly connected. Then, the threaded rod 33 is passed through the interiors of the first through slot 311 and the second through slot 3221. Then, the threaded cap 331 is sleeved on the exposed end of the threaded rod 33, and the two are rotated to form a threaded connection. At this time, under the action of the threaded cap 331 and the threaded rod 33, the first fixing ring 31 and the second fixing ring 32 can be further fixed. And due to the presence of the anti-overflow soft pad 321, when the first fixing ring 31 and the second fixing ring 32 are in a mutually attached state, the anti-overflow soft pad 321 is squeezed, reducing the gap at the connection between the first fixing ring 31 and the second fixing ring 32, thereby preventing the overflow of water.
