Description

Unpowered blast automatic cleaning type dust filtration device
Technical field
The present invention relates to a kind of dust filtration device, especially relate to a kind of unpowered blast automatic cleaning type dust filtration device.
Background technology
Dust filtration device is widely used in the industry of textile industry, nonwoven (non-weaving cloth) production industry and other generation dust pollution.In dust filtration device, the air that conveying fan will have dust, chemical fibre or other impurity is transported in the dust filtration device, dust filtration device separates air with impurity, air ejects from the filter dirt cloth of dust filtration device, impurity and short fiber etc. are separated by dust filtration device, thereby the realization air separates with impurity class material, to reach the effect that purifies air.In traditional dust filtration device, most of short fiber, dust are separated by dust filtration device with impurity, but be attracted on the filter cloth of dust filtration device under the effect of some dust impurity and short fiber blast in dust filtration device, and slowly on filter cloth, accumulate, form the thick short fiber impurity layer of one deck gradually, thereby influenced the air draft of filter cloth, had a strong impact on filter dirt effect.And the difficult cleaning of this type of short fiber impurity layer will be forced to stop to produce and could clear up dust filtration device on the one hand, wastes time and energy also extremely unhygienic environmental protection on the other hand again.
Existing dirt catcher product.In any shape with use which kind of filter medium, its clear assorted device that filters the impurity that produces and all need to have power carries out assorted clearly, these assorted clearly devices are consumed energies not only, and clear assorted effect is not satisfactory.For example the assorted clearly dirt catcher of pulsating is characterized in batch (-type) cleaning impurity, often has complicated electric automatics and drive unit; Clear up dirt catcher at regular intervals No. one time for every under electrical control, the shortcoming of this dirt catcher is: the effect of removal of impurities is downward trend in the neutral of two blanking times, and the effect of filter dirt has reduced 50%.For example hinder the formula dirt catcher more surely, the control of its clearance time is by the decision of the quantity of the impurity that adheres on the filter medium, the filter dirt the course of work in along with the deposition of laying dust on the screen pack surface, the area of screen pack mesh is more and more littler, thereby cause air quantity more and more littler, windage is increasing, represents the parameter of windage will be transferred in the electrical control, form feedback quantity and deliver to the input of PLC, the output signal drive mechanism forms removal of impurities power; This shortcoming that hinders the formula dirt catcher surely is identical with the pulsating dirt catcher.In addition, the clear assorted device of other various forms of dirt catchers all has similar problem to exist.Owing to there is above-mentioned problem, also restricted the increase of the capacity of dirt catcher, dirt catcher with power considers that the effect of cleaning can only be taked the design of multiple-unit formula, and not only a difficult problem of bringing cost to rise to production process is also brought the trouble of working service inconvenience to the user.It is pointed out that in addition being accompanied by above-mentioned defective also has the possibility that the fuselage cycle rocks, and is forcing the manufacturer thicken the material thickness of fuselage.To strengthen the stability of fuselage, this is again a waste.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of unpowered blast automatic cleaning type dust filtration device; This dust filtration device is the power of clear assorted device by means of wind-force, has realized the design of larger capacity; Realize following cleaning, assorted the obtaining at any time of filter screen upward filtration cleared up, not only saved the energy, electric circuit, mechanical component; Also improve filter efficiency greatly, made to simplify the structure, improved the stability of equipment; Maintenance period is prolonged greatly; After tested, the dust content that uses dust filtration device of the present invention to carry out after the air cleaning can reach every cubic metre<0.75 milligram.
