Safe and return dust-less dust exhaust apparatus for lapper

Abstract

The invention relates to a safe and return dust-less dust exhaust apparatus for a lapper. The dust exhaust apparatus is characterized by comprising a suction hood, a dust filtering device and a dust collecting pipe for connecting the suction hood with the dust filtering device, wherein the dust collecting pipe is internally provided with a suction ventilator, and the dust filtering device comprises a box-shaped housing and at least one of layers of plate-shaped dust filtering cores arranged in the housing. According to the dust exhaust apparatus for the lapper, provided by the invention, the conventional filter bag is replaced by the dust filtering cores in the dust filtering device, and the dust filtering device is better in air permeability and less in return dust, so that the dust exhaust apparatus is better in filtering effect, safer in process, capable of being protected by a hard housing, hard to damage and longer in service life. The suction ventilator can be additively provided with a motor speed adjusting device, and the housing is internally provided with the plurality of layers of detachable dust filtering cores, so that the proper dust filtering intensity can be adjusted according to the dust absorption requirements of different occasions such as the different fabrics, therefore, not only can the energy waste be avoided, but also the dust absorption effect can be guaranteed.

Description

technical field [0001] The invention relates to a dust removal device in the field of textile machinery, in particular to a dust suction device for a lapping machine. Background technique [0002] In the textile field, a coiling machine is used to roll the gray cloth. Since the gray cloth contains slurry, it is easy to fall off during the rolling process and generate dust, which will cause environmental pollution in the workshop and damage the health of the operators. Traditional dust removal equipment usually includes a dust collection hood, a suction fan, and a filter structure connected to the dust collection hood. In the filter structure, the filter bag acts as a filter. The air with dust enters the dust filter bag, and the dust is retained, while the air Escaping from the dust bag. However, because the usual dust filter bags are fiber woven bags, such as cloth bags, which have high density and poor air permeability, there are potential safety hazards, and it is easy to...

AI Technical Summary

Problems solved by technology

However, because the usual dust filter bags are fiber woven bags, such as cloth bags, which have high density and poor air permeability, there are potential safety hazards, and it is easy to cause part of the dust to return to the dust collection cover, resulting in dust return and reducing the dust collection effect.
