Feed material lifting device with negative pressure return air cavity

Abstract

This utility model discloses a feed material lifting device with a negative pressure return air chamber, relating to the field of feed conveying technology. The device includes a lifting machine body and a return air hood mounted on top of the lifting machine body. A return material bin is fixedly mounted on one side of the return air hood. Through the arrangement of a transmission assembly, a negative pressure fan, and a scraper filter plate, when the lifting machine body lifts material, a first servo motor drives the transmission assembly to rotate, which in turn drives the negative pressure fan to rotate, generating suction to absorb floating feed particles and transport them through a collection hood pipe to the return material bin. This prevents feed particles from scattering and affecting the air environment. Simultaneously, the transmission assembly drives the scraper filter plate to rotate, scraping the absorbed feed particles into the return pipe and returning them to the hopper. This achieves the recycling and reuse of collected feed, reduces material loss, and prevents feed particles from getting stuck in the mesh of the isolation screen, which would weaken the suction.

Description

Technical Field

[0001] This utility model relates to the field of feed conveying technology, specifically a feed material lifting device with a negative pressure return air chamber. Background Technology

[0002] Feed material elevators are one of the indispensable core equipment in the feed processing industry. They are mainly used to vertically or nearly vertically transport powdery, granular, or fragmented feed raw materials and finished products between various stages of production.

[0003] Existing feed material elevators have certain shortcomings in actual operation. On the one hand, during the feeding, lifting, and discharging processes, the collision between materials and the airflow generated by the equipment operation can easily cause lighter feed particles and dust to be scattered into the surrounding air. This not only causes direct material loss and increases production costs, but also seriously pollutes the workshop working environment, affects the health of employees, and poses certain dust safety hazards. On the other hand, there is usually a certain height difference between the discharge port of the elevator and the receiving port of downstream equipment (such as silos and mixers). When the material falls, it will generate impact, causing the already deposited particles and dust to be raised again, which exacerbates the problem of material dispersion and environmental pollution.
