Abstract

The invention discloses a dust treatment device for wood processing, and belongs to the technical field of dust treatment equipment. The technical scheme of the invention is as follows: external air is sucked into the device through the air inlet pipeline by the turbofan, when the air flow moves rapidly, the opening of the conical air suction pipeline at the fork of the air pipe inclines upwards, so that the air nearby is driven by the moving air flow in the air inlet pipeline to move downwards to form instantaneous negative pressure, the dust floating at the upper end of the conical air suction pipeline flows into the machine body through the conical air suction pipeline and flows into the dust settling chamber, and finally the dust begins to settle under the action of gravity through the water mist sprayed by the spray head, and the filtering wall blocks the dust and finally falls into the bearing disc to be collected.

Description

Dust treatment device for wood working

Technical Field

The invention belongs to the technical field of dust treatment equipment, and particularly relates to a dust treatment device for wood processing.

Background

The wood processing is mainly carried out by mechanical or chemical methods by using wood as raw material, the product still maintains the basic characteristics of the wood, the wood has the advantages of light weight, high strength-weight ratio, good elasticity, impact-resistant texture, rich and beautiful color, easy processing and the like, and the grinding and cutting of the wood are necessary procedures in the processing and production process of the wood. Carpentry can produce a large amount of dust and wood shavings, can produce the sawdust in the course of working, create bits and polish dust etc, it is tiny to polish the operation dust, and difficult the collection, the dust of production not only can increase wood working equipment's wearing and tearing and the normal work that influences the electrical apparatus, still can produce great harm to environment and human body, for the waste that reduces the resource and prevent polluted environment and improve product quality when protecting the workman healthy, must have dust absorption and clarification plant to these processes. In the production at present, every wood working equipment all is equipped with corresponding dust collecting equipment, and dust collecting equipment collects the inside dust of equipment, and the processing apparatus to the dust generally inhales the dust inside through the fan and filters the collection through inside filter screen bag etc. similar device to the dust again, and this kind of mode can reduce the content of dust in the air, but has some defects, such as: on one hand, dry dust, particularly the wood processing environment aimed by the invention, is mostly flammable dust such as wood dust, and if the dry dust is contacted with a circuit in a fan, the dust explosion phenomenon is easy to occur, so the potential safety hazard is higher, on the other hand, the mode of directly filtering by using a filter screen is increased along with the increase of time, so that the filter screen holes are blocked, the gas quantity passing through the filter bag is gradually reduced, the ventilation obstruction is caused, the dust collection capacity is reduced, the filter screen needs to be frequently disassembled and cleaned, the production is inconvenient, the operation management cost is higher, at present, when wood is processed, for example, a patent with the application number of CN201320808283.3 comprises a main dust collection pipe and a dust collection purification device, the main dust collection pipe is arranged above the wood processing device, and the main dust collection pipe is provided with a dust collection port at a corresponding position above each wood processing, although this patent can take the dust air of carrying out and take out, can't will clear away the dust back and send back the circulation that forms the air inside the workshop and flow, lead to equipment to form effectual dust removal only in some region, greatly reduced the dust removal dedusting effect to the workshop, lead to the inside partial region dust concentration in workshop still very high, the condition that dust deflagration can appear, unnecessary loss has been caused, the dust also can be inhaled internal influence healthy by the staff simultaneously, and when filtering the dust, the dust can live the effect that influences air exhaust with the screen cloth jam, need the operation that the staff often cleared up, staff's use is not convenient for, can't satisfy customer's demand. For example, a filter cartridge dust treatment control device disclosed in patent No. CN2017113407240 can perform filter screen self-cleaning by combining reverse rotation with a filter cartridge dust cleaning device with back flushing, but is also troublesome in that it needs to be stopped and manually operated after being used for a period of time.
