Description
Technical Field
The invention belongs to the relevant technical field in the aspect of large-space dust removal, and particularly relates to a multi-stage indirect drive type suction device for large-space dust removal.
Background
Certain processes in cotton, wool, hemp and silk spinning plants, such as cotton mixing, wool selection, ramie softening, opening and carding, discharge a large amount of dust, and some spinning devices, such as open-end machines, discharge a large amount of dust-containing air during the process by using air flows to convey and agglomerate the fibers or to remove waste materials. In a cotton mill with 5 ten thousand spindles, the air discharge amount of a cotton cleaner is more than 12 ten thousand meters per hour. If textile factories do not adopt air purification measures, a large amount of dust-containing air is inevitably diffused, seriously pollutes workshops and surrounding environments, directly harms the health of workers and influences the product quality. The operating speed of textile machinery is increasing, and the dust concentration in the air in the workshop of the spinning department is increased by the expanded use of mechanical cotton picking and metal card clothing in cotton spinning. The requirements of the industrial countries in the world on the air quality of workshops of textile mills are more and more strict, so that the dust removal of the textile mills becomes a prominent problem in the design of new factories and the technical transformation of the original factories. Property of spinning mill dust the dust formed in the spinning process is a mixture of particles of various substances. The constituent substances are mainly classified into organic and inorganic substances. The organic matter comprises fragments, scraps, linters, seed scraps, leaf scraps, etc. of cotton, flax, jute, wool, silk, chemical fiber, etc.; the inorganic substances include clay, sand, asbestos, glass dust and the like. Some dusts (e.g., cotton dust and hemp dust) also contain a proportion of silica dust. Most of this dust is mixed with the fibres during the harvesting of the material, for example during cotton picking, cropping or retting, or during processing, transport and storage. The particle size distribution range of dust in textile production is wide, the shapes of dust particles are complex and various, and most of dust is nontoxic but still has great harm to human bodies. For example, too high a content of silica or silicate dust in the dust can cause pneumoconiosis. Some productive dusts (such as cotton dust, hemp dust, asbestos dust, etc.) which are inhaled by textile workers for a long time and have high concentration are easy to suffer from pneumoconiosis, and some dusts are researched to be also carcinogenic. The hazard of dust increases with increasing dust dispersion. Generally, dust with larger particle size (above 100 microns) can settle faster in air; dust with the particle size of 10-100 microns can be blocked by vibrissa, nasal mucosa and an upper respiratory tract and is not easy to enter the lung; dust larger than 5 microns can partly enter alveoli, while dust particles smaller than 5 microns enter alveoli in larger quantity and most of the dust particles can be deposited in lungs, so that the harm is greatest. In addition, the irritating effect of the dust can lead to an increased incidence of inflammation of the upper respiratory tract in the inhalator and damage to the skin or mucous membranes of the person in contact therewith. According to the harmfulness of the particle size of the dust to human bodies, dust removal of a spinning factory is mainly to remove dust below 15 microns, especially dust below 5 microns. Different dust removal modes are adopted by textile mills for dust contained in outdoor atmosphere and dust emitted in workshops. Under the condition of low sanitary standard, outdoor air is generally directly sent to a vehicle or is washed by an air conditioning water spray chamber and then sent to the vehicle. When the requirements of sanitary standard and product quality are high or the air pollution is serious, the outdoor air must be strictly purified by a dust remover and then can be sent into a workshop. The dust emitted in the workshop is removed mainly by adopting a ventilation mode of upper air supply and lower air exhaust. Comprehensive air supply and comprehensive air exhaust can meet the requirements of temperature and humidity control of a workshop, can reduce the dust amount which is comprehensively diffused, and can exhaust free dust in the air to dust filtration equipment. The processing equipment which locally emits dust takes a sealing measure, and air suction is utilized at the dust emitting point and nearby dust emitting points to enable the dust-containing air to pass through a dust suction cover, a dust suction pipeline, a dust remover, a ventilator and dust discharging equipment, and the air is purified and then discharged out of the room or returned to a workshop. Dust removal in textile mills has three basic forms according to the dust remover arrangement method: firstly, the dust remover is directly arranged on the processing equipment emitting dust, the dust is collected on the spot, and the purified air returns to the workshop on the spot. The form is simple, the layout is compact, and the maintenance is convenient. Dust collecting and removing systems at two positions of drafting and sliver discharging on a cotton spinning drawing frame belong to the category; secondly, dispersion type: one or a plurality of air suction of dust dispersing points in the same process flow are combined into a system. The dust collector and the fan are installed near the equipment emitting dust, and are generally taken care of by the production workers themselves. The mode has the advantages of short pipeline, simple arrangement, easy air quantity balance and the like, but the collection of waste materials is more troublesome. The dust removal of a small dust remover used by the opening and picking combination machine or the carding machine is distributed; ③ centralized type: a plurality of dust scattering points or dust scattering points of the whole workshop, even the air suction of the dust scattering points of the whole factory are integrated into a dust removal system, a special dust removal chamber is arranged and managed by a specially-assigned person, and the dust removal system is often used in combination with automatic collection and packaging of blanking, feet and waste materials. The characteristic of this form is that the amount of wind is big, the pipeline is long and complicated, but the collection of leftover bits and waste material and packing realize mechanization and automation easily. But the dust remover that is used for one type of large space of weaving factory now is direct more to set up dust absorption fan inside the wind channel, and single fan provides suction through longer single wind channel, and power is lower, and the absorptive air that contains dust, dust is direct to contact with the flabellum and the motor of fan, and dust, the dust that subside easily divide and form easily inside the motor of fan, on the flabellum and pile up, cause the result that influences dust remover work efficiency.
