Description
Technical Field
The invention belongs to the technical field of wood processing, and particularly relates to a dust removing system for wood furniture production.
Background
In recent years, with the rapid development of science and technology, wood processing enterprises gradually enter a large-scale fine intelligent production stage, as is well known, in the wood processing process, the following processes of cutting, milling, drilling, sanding and the like are often required, in the processes, the devices required to be used are a grinding machine, a cutting machine, a processing center, a sanding machine, a milling machine, a drilling machine, a lathe and the like, and with the heavy use of such automatic devices, a large amount of wood dust is generated as a result;
as is known, wood dust can be divided into wood chips and wood powder according to the particle size, the wood chips are generally from milling and sawing equipment, and the wood powder is mainly from sanding equipment; both wood chips and wood flour are flammable. Wood flour produced by cutting wood can float in the air for a long time; after being inhaled by human body, the health of human body is greatly damaged. Therefore, as a household production enterprise, the treatment of the wood dust is particularly important from the aspects of environmental protection requirements and human body safety.
In addition, the risk in terms of production safety is dust explosion, which refers to an explosion phenomenon that occurs when combustible dust suspended in air touches an open flame or an ignition source such as an electric spark. The dust explosion means that the combustible dust meets a heat source within the explosion limit range, the flame instantly spreads in the whole mixed dust space, the chemical reaction speed is extremely high, a large amount of heat is released at the same time, high temperature and high pressure are formed, the energy of the system is converted into mechanical energy and the radiation of light and heat, and the destructive power is very strong. Along with the popularization of the humanization concept and the composition of a novel harmonious society, wood dust explosion prevention is very necessary. The explosion of combustible dust should be subject to three conditions, namely the dust itself is explosive and the dust must be suspended in and mixed with air to an explosive concentration with a sufficient source of fire to cause the dust to explode. The wood particles can be exploded after reaching 25-65g/m3, and the existence of dust explosion inducers and enough induced energy are sufficient conditions for dust explosion. In the past, because the understanding and attention on dust explosion are lacked, the dust explosion phenomenon is often represented as an accidental sudden event. The causes of this are mainly open flames, hot particles or surfaces, heat accumulation, heat rays, mechanical friction such as sparks generated by sanding and collision, sparks generated by electrical or electrostatic discharge, etc.
In conclusion, dust removal treatment needs to be performed on a processing workshop, but most of existing dust removal systems simply perform dust filtration and collection, so that not only is the dust removal effect poor, but also if the dust concentration cannot be guaranteed to be controlled, the safety of a processing place cannot be guaranteed, continuous operation cannot be performed, regular cleaning is required after long-time use, filtered dust is accumulated, dust is easily splashed to form secondary pollution when disassembly and maintenance are performed, the effect is not ideal, sparks are easily generated due to friction during the dust extraction process, and once sparks are generated, explosion is more likely to occur, and great potential safety hazards are caused.
