Description

Technical Field

[0001] The utility model relates to the technical field of dischargers, in particular to a star-shaped discharger with high-efficiency discharge. Background Art

[0002] The discharger is the main equipment used for dust removal equipment to discharge dust, air supply and other equipment to feed materials. It is widely used in powdery materials and granular materials. Among them, the star-shaped discharger has the best working efficiency and stability. The star-shaped discharger has a compact structure and beautiful appearance. It is widely used in environmental protection, metallurgy, chemical industry, grain, food and other departments.

[0003] When the existing star-shaped discharger discharges materials, the materials are easily adhered to the rotating impeller and are not easy to fall, which affects the discharge efficiency. In addition, the materials rely on their own gravity to fall during discharge. In order to ensure thorough discharge, the impeller rotates slowly, resulting in low discharge efficiency and difficulty in meeting people's usage needs. Utility Model Content

[0012] Compared with the prior art, the utility model provides a star-shaped discharger with high efficiency in discharge, which has the following beneficial effects:

[0013] 1. The star-shaped discharger with high efficiency discharge starts the air pump to assist in discharge when discharging.

[0014] 2. For this efficient unloading star-shaped unloader, when the conveying trough moves to other positions, the abutment plate and the eccentric ring, and the spring, through their own elastic force, will drive the guide rod to retract into the auxiliary cavity, closing the opening of the airway. At the same time, the sealing plate will fit with the surface of the rotating tube to receive the material, making it convenient for the next wave of unloading. BRIEF DESCRIPTION OF THE DRAWINGS

An output shaft 12 is fixedly installed on the output end of the motor 11, and a coupling 14 is fixedly installed on one end of the output shaft 12. The output shaft 12 is connected to the rotating tube 4 through the coupling 14.

[0022] By starting the motor 11, the rotating tube 4 is driven to rotate, and the rotating tube 4 drives the blade 5 to rotate, so that the conveying trough 13 that has received the material at the feed port 2 is conveniently rotated to the discharge port 3 for unloading. At the same time, the conveying trough 13 that has unloaded the material is rotated to the feed port 2 to receive the material again. Multiple conveying troughs 13 work in a cycle to unload the device that needs to unload.

At the same time, the guide rod 81 moves downward to allow the opening of the air channel 85 to leak out in the conveying trough 13, and the gas generated by the air pump 9 can be sprayed out through the air channel 85 on the guide rod 81, so that the material can be quickly pushed out of the conveying trough 13 for unloading.

[0027] Working principle: This high-efficiency star-shaped discharger is installed at the outlet of the device that needs to be discharged, and then the motor 11 is started to drive the rotating tube 4 to rotate. The rotating tube 4 drives the blade 5 to rotate to discharge the material, and the air pump 9 is started to assist in the discharge. When a conveying trough 13 rotates to the lower discharge port 3, the auxiliary discharge assembly 8 on the conveying trough 13 will be pressed by the eccentric ring 7, driving the guide rod 81 and the sealing plate 82 to move downward, so as to facilitate the material at the bottom of the conveying trough 13 to be pushed away, and at the same time the guide rod 8 1 can be moved downward to leak the opening of the air channel 85, and the gas generated by the air pump 9 can be ejected outward through the air channel 85 on the guide rod 81, so that the material can be quickly pushed out of the conveying trough 13 for unloading. When the conveying trough 13 moves to other positions, the abutment plate 84 and the eccentric ring 7 and the spring 83 will drive the guide rod 81 to retract into the auxiliary cavity 6 through their own elastic force, and close the opening of the air channel 85.
