Dust cleaning device on second-hand household appliance

Abstract

The invention discloses a dust cleaning device on a second-hand household appliance. The dust cleaning device comprises a dust removal chamber, and a rotating disc is arranged at the bottom of the center in the dust removal chamber; vertical air supply pipes are arranged on the two sides of the rotating disc, and inclined air blowing pipes are connected to the air supply pipes; the upper ends of the air supply pipes penetrate through through grooves formed in the two sides of the upper end of the dust removal chamber; a dust suction mechanism is fixed at the position, between the through grooves, on the top of the dust removal chamber and comprises a dust suction box, a dust suction pipe inserted into the side wall of the dust suction box, a dust collecting box fixed to the top end face ofthe inner side of the dust removal chamber and water contained in the dust collecting box; one end of the dust suction pipe penetrates through the dust removal chamber and is fixed to the dust collecting box, and the other end of the dust suction pipe is immersed in the water in the dust collecting box; a conical air guide cylinder is arranged on the water above a hook, and the upper end of the air guide cylinder is communicated with a V-shaped air guide channel; the air guide channel is communicated with air outlets formed in the two side walls of the upper end of the dust suction box separately, and the air outlets are communicated with the upper ends of the air supply pipes respectively. According to the device, dust on the second-hand household electrical appliance can be removed conveniently, and secondary pollution cannot be caused.

Description

Technical field: [0001] The invention relates to the technical field of household appliances, in particular to a dust cleaning device on second-hand household appliances. Background technique: [0002] With the acceleration of electronic information technology updates and the strengthening of people's awareness of environmental protection and the concept of circular economy, obsolete small household electrical appliances have gradually changed from being discarded at will to being collected and disposed of in a standardized manner. Recycled household electrical appliances have been used or put aside for a long time, causing a large amount of dust to accumulate on the surface of the household appliances. If the pre-treatment is not carried out, it will bring dust secondary pollution to the workers in the inspection and maintenance of the remanufacturing production line, which will affect the operation. At the same time, the existence of fine dust particles will also cause the...

Problems solved by technology

Recycled household electrical appliances have been used or put aside for a long time, causing a large amount of dust to accumulate on the surface of the household appliances. If the pre-treatment is not carried out, it will bring dust secondary pollution to the workers in the inspection and maintenance of the remanufacturing production line, which will affect the operation. The health of personnel, at the same time, the existence of fine dust particles will also cause the problem of inaccurate detection and maintenance accuracy

At present, second-hand processing factories or household appliance cleaning companies place household appliances to be repaired or cleaned in the open air, and at the same time use induced air blowing to remove dust on the surface of household appliances, which will lead to secondary pollution caused by dust, and because of fixed Type of spraying, prone to incomplete cleaning
