Dust removal system for casting workshops

Abstract

The invention belongs to the technical field of casting equipment, and particularly relates to a casting workshop dust removal system. The casting workshop dust removal system comprises a dust remover, a dust removal main pipe, a plurality of dust removal branch pipes, a plurality of telescopic dust accumulation covers, a control system and a frequency converter; the dust remover is arranged on one side of a workshop; one end of the dedust removal main pipe is communicated with the dust remover; a plurality of dust suction openings are formed in the dust removal main pipe at intervals; one endof each dust removal branch pipe is communicated with a dust suction opening in the corresponding dust removal branch pipe, and the other end is communicated with a corresponding telescopic dust accumulation cover; the plurality of dust accumulation covers are arranged in the workshop at intervals, and a smoke sensor is arranged in each telescopic dust accumulation cover; a signal input end of the control system is connected with a signal output end of each smoke sensor; a signal input end of the frequency converter is connected with a signal output end of a controller. The casting workshop dust removal system is used in traditional casting workshops, adoption of the dust remover, the telescopic dust accumulation covers and the control system is capable of realizing collecting and treating of smoke dust generated by air gouging, welding and relief grinding in the workshop, and discharging of the treated smoke dust into the atmosphere, and pollution to the atmosphere is reduced.

Description

technical field [0001] The invention belongs to the technical field of foundry equipment, in particular to a dust removal system in a foundry. Background technique [0002] In the foundry industry, in the cleaning workshop, the welding, relief grinding, gouging and cleaning processes of castings are mainly carried out. The gouging work is carried out in a specific room, which is equipped with a dust collector, which can effectively suck away the smoke and dust. , After being filtered, it is discharged into the atmosphere; welding and shovel grinding operations will also generate smoke, but the welding and shovel grinding fume treatment was not considered in the early stage of plant construction, and there was no dust removal system, resulting in a very poor environment in the plant.

[0002] In the foundry industry, in the cleaning workshop, the welding, relief grinding, gouging and cleaning processes of castings are mainly carried out. The gouging work is carried out in a specific room, which is equipped with a dust collector, which can effectively suck away the smoke and dust. After being filtered, it is discharged into the atmosphere; welding and shovel grinding operations will also generate smoke and dust, but the treatment of welding and shovel grinding dust was not considered in the early stage of plant construction, and there was no dust removal system, resulting in a very poor environment in the plant

[0003] At present, there are various dust collectors on the market, and there are many types. It is very simple to deal with the dust alone. However, if the size of the castings produced is relatively large, a crane must be used for transfer. The crane cannot be hindered in the air. Moreover, the workshop is relatively large large, and the welding and shovel grinding operations are relatively scattered, which makes it impossible to directly use the existing dust removal equipment for dust removal work
