[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. By sleeved a quick-connect sleeve on the outside of the connection between the first reinforcement ring and the second reinforcement ring, when the silo pump or the fluidizer needs to be repaired, the auxiliary rod is inserted into the outside of the quick-connect sleeve and tightened. Then, the blocking column is pressed with a slender column. When the blocking column completely leaves the blocking groove, the quick-connect sleeve is driven to rotate by rotating the auxiliary rod. The quick-connect sleeve continuously moves away from the first reinforcement ring under the action of the thread until the first reinforcement ring is completely separated from the quick-connect sleeve. The separation of the silo pump and the fluidizer is completed. The purpose of separating the silo pump and the fluidizer can be achieved without removing multiple bolts and nuts, which effectively improves the maintenance efficiency of the staff.

[0016] 2. By installing a tight ring on the top of the first reinforcement ring, when the fluidizer is connected to the silo pump, fix the fluidizer and then rotate the quick-connect sleeve. The first reinforcement ring will continue to move upward under the action of the thread. The fluidizer drives the first reinforcement ring to move upward, and the first reinforcement ring drives the tight ring to move upward until the quick-connect sleeve can no longer be turned. This time, the tight ring enters the rubber sleeve. Under the action of the rubber sleeve and the tight ring, the connection sealing between the silo pump and the fluidizer is further improved.

[0017] 3. By installing a threaded rod in the accommodating cavity, when assembling the upper and lower bins, align the first connecting flange and the second connecting flange, then rotate the threaded rod upward 180 degrees, and then rotate the threaded ring. The threaded rod continues to move downward under the action of the thread, and the threaded rod drives the gasket to move downward until the threaded ring can no longer be rotated. The assembly of the upper and lower bins is completed, which facilitates the assemblers to install the bin pump. BRIEF DESCRIPTION OF THE DRAWINGS

A mounting groove 102 is provided on the outside of the first reinforcement ring 31, and a blocking column 10 is slidably connected in the mounting groove 102. One end of the blocking column 10 is engaged in the mounting groove 102, and a spring 103 is provided on one end of the blocking column 10 and one side of the mounting groove 102 for resetting the blocking column 10. A blocking groove 101 adapted to the blocking column 10 is provided on the outside of the quick-connect sleeve 3, and the other end of the blocking column 10 is engaged in the blocking groove 10 1, as a preference, the surface of one end of the blocking column 10 close to the blocking groove 101 is an arc surface, and the arc surface design can facilitate the blocking column 10 to enter the blocking groove 101, and the bottom end of the outer side of the quick-connect sleeve 3 is fixedly connected to the first indicator block 91, and the outer side of the fluidizer 4 is fixed with a second indicator block 92 corresponding to the first indicator block 91. The installation positions of the first indicator block 91 and the second indicator block 92 are set according to the thread stroke at the connection between the quick-connect sleeve 3 and the first reinforcement ring 31. When rotating the quick-connect sleeve 3, the first indicator block 91 and the second indicator block 92 are first connected. Align the indicator block 92, and then rotate the quick-connect sleeve 3 until the quick-connect sleeve 3 cannot be rotated. At this time, the blocking column 10 just enters the blocking groove 101, and the connection firmness of the fluidizer 4 and the silo pump 1 is just right, avoiding damage to the sealing components caused by the connection being too tight. The blocking column 10 is engaged in the blocking groove 101 to avoid the quick-connect sleeve 3 from accidentally rotating under force, which helps to improve the connection firmness between the quick-connect sleeve 3 and the first reinforcement ring 31. Auxiliary rods 33 are equidistantly inserted on the outside of the quick-connect sleeve 3. The auxiliary rods 33 are connected to the quick-connect sleeve 3 through threads, which facilitates the rotation of the quick-connect sleeve 3.

When the blocking column 10 completely leaves the blocking groove 101, the quick-connect sleeve 3 is driven to rotate by rotating the auxiliary rod 33. The quick-connect sleeve 3 continues to move away from the first reinforcement ring 31 under the action of the thread until the first reinforcement ring 31 is completely separated from the quick-connect sleeve 3, completing the separation of the silo pump 1 and the fluidizer 4. The purpose of separating the silo pump 1 and the fluidizer 4 can be achieved without removing multiple bolts and nuts, which effectively improves the maintenance efficiency of the staff.

[0028] Example 2

[0029] Please refer to Figure 3As shown, the present invention provides a silo pump for pneumatic conveying. This embodiment adopts the same technical solution as the first embodiment, except that a tight ring 34 is fixedly connected to the top of the first reinforcement ring 31, and a rubber sleeve 35 adapted to the tight ring 34 is embedded in the bottom end of the second reinforcement ring 32. The tight ring 34 is embedded in the rubber sleeve 35 to improve the sealing performance of the connection between the first reinforcement ring 31 and the second reinforcement ring 32. Preferably, the top of the tight ring 34 is an arc surface, which is set to an arc surface to facilitate the tight ring 34 to enter the rubber sleeve 35.

[0030] During use, when the fluidizer 4 is connected to the silo pump 1, fix the fluidizer 4, and then rotate the quick-connect sleeve 3. The first reinforcement ring 31 continues to move upward under the action of the thread, and the fluidizer 4 drives the first reinforcement ring 31 to move upward. The first reinforcement ring 31 drives the tight ring 34 to move upward until the quick-connect sleeve 3 cannot be rotated. This time, the tight ring 34 enters the rubber sleeve 35. Under the action of the rubber sleeve 35 and the tight ring 34, the connection sealing between the silo pump 1 and the fluidizer 4 is further improved.
