Description

Technical Field

[0001] The invention belongs to the technical field of dry bulk material unloading, and in particular relates to a dust collecting dry ash bulk loader. Background Art

[0002] Typical dry ash bulk loaders utilize a single discharge lift head that also serves as a dust extraction port. There's a significant height difference between the dry bulk material being unloaded from the storage silo and onto the flatbed truck, and the presence of a high concentration of fine ash in the bulk material creates significant dust during unloading, impacting the on-site environment and the occupational health and safety of on-site workers. Summary of the Invention

DETAILED DESCRIPTION

[0011] The technical solution of the present invention is further described below with reference to examples and drawings.

[0012] Figure 1 As shown, a dust collecting dry ash bulk loader includes a base 1, a dust removal fan 2, a dust extraction air duct 3, a lifting motor 4, a wire rope drum 5, a wire rope 6, a pulley 7, a discharge telescopic head 8, a contact material level meter 9, a dust extraction telescopic head 10, a dust collection hood 11, and a dust collection soft curtain 12. The base 1 is installed on the unloading platform, and the dust removal fan 2, dust extraction duct 3, lifting motor 4, wire rope drum 5, pulley 7, unloading telescopic head 8, and dust extraction telescopic head 10 are installed and fixed on the base; one end of the dust extraction duct 3 is connected to the dust removal fan 2, and the other end is connected to the unloading telescopic head 8 and the dust extraction telescopic head 10; one end of the wire rope 6 is fixed on the wire rope drum 5, and the other end is fixed on the unloading telescopic head 8 and the dust extraction telescopic head 10 through the pulley 7; the contact material level meter 9 is fixed on the unloading telescopic head 8; the dust collection hood 11 is fixed on the unloading telescopic head 8 and the dust extraction telescopic head 10, and the dust collection soft curtain 12 is fixed on the dust collection hood 11.

[0013] The body and blades of the dust removal fan 2 are made of wear-resistant alloy steel, and the dust extraction air duct 3 is made of wear-resistant alloy steel; the core of the steel wire rope 6 is made of metal core material; the telescopic joints of the unloading telescopic head 8 and the dust extraction telescopic head 10 are made of industrial wear-resistant canvas, and other connecting chutes and unloading heads are made of wear-resistant alloy steel; the dust collection hood 11 is made of stainless steel; and the dust collection soft curtain 12 is made of PVC.

[0014] The dust removal fan 2 simultaneously controls the dust extraction of a discharge telescopic head 8 and two dust extraction telescopic heads 10 through the dust extraction air duct 3; the lifting motor 4 simultaneously controls the lifting and lowering of a discharge telescopic head 8 and two dust extraction telescopic heads 10 through a multi-section wire rope drum 5, a wire rope 6, and three pulleys 7, and at the same time drives the lifting and lowering of the dust collection hood 11 and the dust collection soft curtain 12.

[0015] Working process and principle: The base 1 is fixed to the silo's unloading platform. When unloading the silo, the lifting motor 4 is first started to rotate the wire rope drum 5. Through the rotation of the wire rope 6 and three pulleys 7, the unloading telescopic head 8 and two dust extraction telescopic heads 10 are lowered above the flatbed truck. At the same time, the dust collection hood 11 and dust collection curtain 12 are lowered until the bottom of the dust collection curtain 12 just falls on the flatbed truck receiving hopper. The dust extraction fan 2 is turned on, and dust is extracted from the outlets of the unloading telescopic head 8 and the two dust extraction telescopic heads 10 through the dust extraction air duct 3.

[0016] The shut-off valve at the silo outlet is opened, and the material is unloaded onto a flatbed truck through the telescopic discharge head 8. The generated dust is sucked away by the dust suction ports of the telescopic discharge head 8 and two telescopic dust extraction heads 10. A small amount of dust that is not sucked away is prevented from escaping to the outside by the dust collection hood 11 and the dust collection soft curtain 12, and is then sucked away by the dust suction ports of the telescopic discharge head 8 and two telescopic dust extraction heads 10. The dust-laden air is sent into the silo by the dust removal fan 2, and is purified by the dust collector on the silo before being discharged.

[0017] When the material is unloaded to a certain height, the contact level meter 9 responds, and the lifting motor 4 slowly lifts the unloading telescopic head 8 and the dust extraction telescopic head 10 until the material is unloaded to the top of the carriage to complete the entire unloading process.

[0018] The body and blades of the dust removal fan 2 are made of wear-resistant alloy steel, and the dust extraction air duct 3 is made of wear-resistant alloy steel; the core of the steel wire rope 6 is made of metal core material; the telescopic joints of the unloading telescopic head 8 and the dust extraction telescopic head 10 are made of industrial wear-resistant canvas, and other connecting chutes and unloading heads are made of wear-resistant alloy steel; the dust collection hood 11 is made of stainless steel; the dust collection soft curtain 12 is made of PVC to reduce equipment wear and increase the service life of the equipment.
