Description

Technical Field

[0001] This utility model belongs to the field of limestone processing technology, and in particular relates to a dust removal and ash conveying device. Background Technology

[0002] Currently, a large amount of dust is generated during the processing of limestone. Most of this dust is stored inside the ash storage silo. When the amount of dust inside the ash storage silo reaches a set value, it is transferred to the ash transport vehicle by a conveying device and transported away.

[0003] A Chinese patent application with publication number CN219116669U discloses a dust collection and conveying device for calcium carbide furnace tail gas. This device automatically transports dust to a transport vehicle using a base plate, a first ash storage bin, an ash inlet pipe, a first ash outlet pipe, and a conveying mechanism. While this technology can transport dust to the transport vehicle in a sealed environment without requiring manual handling, it lacks dust suppression and discharge capabilities. When the dust is discharged into the transport vehicle, it scatters, polluting the surrounding environment, obstructing visibility, and hindering the transport and transfer of dust by personnel, making it unsuitable for use. Utility Model Content

[0004] The purpose of this utility model is to provide a dust removal ash conveying device. By combining the conveying component and the dust prevention component, it solves the problem that the existing dust removal ash conveying device does not have a discharge dust suppression function, and generates a large amount of dust pollution to the surrounding environment when the dust removal ash is discharged into the transfer vehicle.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

The exhaust fan sucks the dust into the feeding shell, and the filter screen retains the dust inside the feeding shell. The first motor, in conjunction with the rotating shaft and scraper, sends the dust into the discharge square pipe. The discharge square pipe discharges the dust into the hopper of the transfer vehicle, preventing the dust from generating a large amount of dust during the discharge process due to excessive conveying speed.

[0015] 2. This utility model uses a dustproof component to absorb and filter the dust generated during the ash removal process, preventing the dust from spreading and polluting the surrounding environment.
