AI Technical Summary
The existing pneumatic conveying equipment lacks a dust removal mechanism when unloading, which causes the ash overflow and cannot be handled, which can easily cause harm to the staff. The ash temperature drops and forms a block shape, resulting in congestion in the discharge port of the feeder and reducing the ash efficiency.
A pneumatic conveying anti-blocking device under the ash bucket was designed. The ash-breathing structure is driven to rotate the shaft of the feeder through the motor, and the fixed rod is used to rotate the inside of the feeder shell to disperse the wet or blocky ash material to avoid Block and improve the efficiency of lowering the ash, while using the sound-absorbing holes and sound-absorbing cotton pads on the inner side of the silent cover to absorb the motor noise.
Effectively avoid clogging of ash, improve the efficiency and work efficiency of ash, and reduce noise through silent design and improve the silent effect.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pneumatic conveying equipment, in particular to an ash dispersing structure under an ash hopper of a pneumatic conveying anti-blocking device. Background Art
[0002] Ash hopper refers to the bucket-shaped furnace bottom structure formed at a certain inclination angle (usually 50°~55°) at the bottom of the furnace of a power plant. It is mainly used to cool and collect ash and discharge it in solid form. For the combustion chamber of a solid slag discharge boiler, the lower part of the front and rear water-cooled walls bend inward to form a cold ash hopper. Its main function is to collect, cool and automatically discharge ash.
[0003] When pneumatic conveying equipment is unloading, an ash hopper and a feeder are required. Most of the existing feeders are single pipes without corresponding dust removal mechanisms, resulting in the inability to process the overflowed ash, which is easy to cause harm to the health of the workers. Although the ash is processed by the feeder, the temperature drops, which will cause the ash to get wet and form lumps, which will easily cause congestion at the discharge port of the feeder and reduce the ash unloading efficiency of the device. For this reason, we proposed a pneumatic conveying anti-blocking device ash hopper ash dispersing structure to solve the above problems. Utility Model Content
