Dedusting and charging device for ore aggregate machine-made sand

Abstract

The invention discloses a dedusting and charging device for ore aggregate machine-made sand. The dedusting and charging device for the ore aggregate machine-made sand comprises a main rack, a discharging assembly, a dust suction fan and a winch with a lifting rope, wherein the discharging assembly is provided with a fixed cylinder and a telescopic cylinder; a feeding assembly in butt joint with a stock bin is arranged above the fixed barrel, and a dust suction pipe connected with the dust suction fan is arranged on the side face of the fixed barrel; the telescopic cylinder comprises an upper connecting frame, a lower discharging end and a plurality of sections of telescopic cylinders connected between the upper connecting frame and the lower discharging end; the upper connecting frame is connected with the lower end part of the fixed cylinder; the lower discharging end is provided with a discharging port; a level gage is arranged at the discharging port; and a material guiding and dedusting assembly is arranged between every two sections of telescopic cylinders, and a dispersing assembly is further arranged in the fixed cylinder. The dedusting and charging device for the ore aggregate machine-made sand is good in flexibility, has a good dedusting effect, can avoid dust raising and collect dust in the sand, and enables the on-site charging environment to be good and pollution to be little.

Description

technical field [0001] The invention relates to the technical field of machine-made sand production, in particular to an ore aggregate machine-made sand dust removal and charging device. Background technique [0002] Machine-made sand and gravel aggregate is prepared by crushing with a stone crusher. During the preparation of traditional machine-made sand and gravel aggregate, a large amount of fine dust adhering to the surface of the aggregate is often produced, and the particle size is about 0.075mm or less. . This part of the dust generates a large amount of dust during the discharge and transportation process, which seriously pollutes the production environment. [0003] At present, in the production process of machine-made sand and gravel, the dust is mainly treated by bag vacuuming and electric vacuuming, which can partially remove the dust existing on the surface of the machine-made sand and gravel aggregate and reduce the amount of dust generated. However, this The...

This part of the dust generates a lot of dust during the discharge and transportation process, which seriously pollutes the production environment

[0003] At present, in the production process of machine-made sand and gravel, the dust is mainly treated by bag vacuuming and electric vacuuming, which can partially remove the dust existing on the surface of the machine-made sand and gravel aggregate and reduce the amount of dust generated. However, this The cost of the two methods is relatively high, and the effect of dust removal is still not up to the ideal requirements, so that it is still accompanied by a large amount of dust release, and the dust recovery is difficult

[0004] Chinese utility model patent (publication number: CN212469096U) disclosed a machine-made sand winnowing dust removal equipment in 2021, including a dust removal box, a feed hopper connected to the top of the dust removal box, and a feed pipe connected to the outlet of the feed hopper. There is a discharge port at the bottom of the dust removal box, and a blower is connected to the dust removal box. There is a buffer plate inside the dust removal box. The buffer plate is located between the feed pipe and the blower. , the dust collection box is connected with a dust collection pipe, the dust collection pipe is located on the side opposite to the blower and close to the top of the dust collection box, and the dust collection pipe is connected with an exhaust fan. Although this utility model can improve the dust removal effect, its structure is relatively fixed and flexible. The performance is not high, and it can be used with different sizes of loading vehicles during the loading process, and the dust removal effect for continuous large batches of sand is not good.
