Description

Technical Field

[0001] The utility model relates to the technical field of machine-made sand dust removal, in particular to a machine-made sand dust removal device. Background Art

[0002] Artificial sand refers to sand processed by sand making machines and other ancillary equipment. The finished product is more regular and can be processed into sand of different rules and sizes according to different process requirements, which can better meet daily needs. Artificial sand requires professional equipment to produce qualified and applicable sand and gravel.

[0003] A Chinese patent document with application number CN202222770112.8 in the related technology proposes a machine-made sand dust removal device, which includes a frame through a compensation mechanism, the frame is fixedly connected to the chassis, a wind tube is arranged on the inner side of the frame, a fan is installed inside the wind tube, a sealing cover is fixedly connected to the inner side of the wind tube by bolts, a cloth bag is arranged on the sealing cover, an air duct is arranged at the front end of the wind tube, a dust collecting hood is installed at one end of the air duct, a sealing plate is fixedly connected to the inner side of the dust collecting hood by bolts, and a plurality of through grooves are opened on the lower side of the sealing plate. When the fan inside the wind tube starts to work, the dust collecting hood will perform secondary cleaning on the dust floating on the top of the machine-made sand through the through grooves on the lower side of the sealing plate, and then the sucked dust will enter the cloth bag through the air duct and the wind tube in turn, so as to facilitate the staff to carry out secondary recovery of the dust.

[0004] With regard to the above-mentioned related technologies, the inventors believe that the following defects exist: the device starts the fan, and the dust collecting hood sucks the dust into the fan and then flows into the bag. However, the dust may be mixed with a large amount of impurities. When the fan comes into contact with the impurities, it is easy to cause damage to the fan, thereby directly affecting the dust removal efficiency of the dust removal shell. Moreover, this method can only collect dust, but it is difficult to effectively process the dust, which greatly reduces the practicality of the device. In view of this, a machine-made sand dust removal device is proposed to solve the above problems. Utility Model Content
