Technical Field

The utility model relates to an environmental protection field is a collecting device to produced dust in the industrial production process.

Background

In industrial production processes, some production facilities generate a large amount of dust. The dust emitted into the air can pollute the workshop environment, is discharged outside the workshop and can pollute the atmospheric environment. The types and characteristics of dust produced by different factories and different production equipment are very different.

Thus, there are many different classes of dusters. Bag-type dust collectors, which use a bag to filter dust from air, are one of the major categories. The bag-type dust collector is favored because the dust collection efficiency is high and can reach the national discharge standard. Therefore, the bag-type dust collector is a main product of a plurality of environment-friendly equipment manufacturers, in particular to a pulse bag-type dust collector.

The filter cloth is used for filtering dust with high efficiency. But dust will quickly accumulate on the filter cloth during use. If the filter cloth is not cleaned in time, the air permeability of the filter cloth is greatly reduced. This requires the addition of a soot cleaning device. The bag-type dust collector can be classified differently due to different means for dust removal. In general, the existing bag-type dust collector is a very mature dust collector.

Detailed Description

In order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The unpowered dust removal bag-type dust collector is mainly formed by welding steel plate materials except for the bag (5). From top to bottom, the dust remover mainly comprises an upper box body (1), a middle box body (6), a dust remover (11), a dust hopper (10) and the like. [ in the figure: the air inlet pipe (2) can be regarded as a component of the upper box body (1). The upper flower plate (3), the upper short pipe (4), the air outlet pipe (7), the lower flower plate (8), the lower short pipe (9), the cloth bag (5) and the like can be regarded as part of the middle box body (6).

The upper flower plate (3) is provided with a plurality of openings, and an upper short pipe (4) is welded below the openings. The lower pattern plate (8) is also correspondingly provided with an opening, and a lower short pipe (9) is welded above the opening. Two ends of the cloth bag (5) are fastened on the upper short pipe (9) and the lower short pipe (9). The ash cleaner (11) is hung on the upper short pipe (4). Structurally, it is emphasized that: the central lines of the open pore of the upper pattern plate (3), the open pore of the upper short pipe (4), the cloth bag (5), the open pore of the lower pattern plate (8) and the lower short pipe (9) are on the same vertical line, namely the upper part and the lower part are through.

The ash hopper (10) part and the ash discharging device are similar to other existing dust removers, belong to conventional designs and are not described again.

When a fan in the dust removal system is started, the unpowered dust removal bag-type dust remover enters a working state:

(see FIG. 1, schematic diagram)

The dusty air flow enters the upper box body (1) from the air inlet pipe (2). Then the dust-containing air flow changes direction and vertically enters each cloth bag (5) from top to bottom. Those large and heavy dust will fall directly into the lower dust hopper (10) by its own weight and inertia. The small and light floating dust can be attached to the inner wall of the cloth bag (5) along with the air flow. The dust is left by the air flow in the cloth bag (5) and escapes from the pores of the cloth bag (5). After passing through the cloth bag (5), the air flow becomes clean air flow. They are discharged into the atmosphere after going out from the air outlet pipe (7) on the middle box body (6).

And the dust attached to the inner wall of the cloth bag (5). The dust will build up thicker and thicker until the gravity force is greater than the adhesion force, and will slide down in bulk like an avalanche and will fall directly into the lower hopper (10).

However, we often wait until this happens. Because then the filtration resistance of the cloth bag is too great. At this time, the dust-containing air quantity processed by the unpowered dust-cleaning bag-type dust remover according to the requirement can be reduced. This does not meet the dust removal system design requirements. Therefore, the ash cleaner (11) is arranged to forcibly clean the ash of the cloth bag, namely, the dust layer is not too thick.

The dust removing mode of the unpowered dust-cleaning bag-type dust remover belongs to the bag-in-bag filter type dust removal.

The ash cleaner of the unpowered ash-cleaning bag-type dust collector is arranged above each bag. When the unpowered dust removal bag-type dust collector works, the bag-type dust collector can continuously flap the bag in a left-right swinging mode, and the dust filtering work of the bag cannot be influenced.

The cloth bag ash cleaner is a piece of long strip-shaped cloth, one end of the cloth is hung on a lifting hook, and the lifting hook is fixed on the inner wall of the upper short pipe.

The unpowered ash removal cloth bag ash remover has no power and swings by the downward wind power at the upper opening of the cloth bag and the pendulum principle.

In addition, in order to prevent the cloth bag of the dust remover from dewing, the inner sides of the four walls of the middle box body are insulated.

A plurality of drawer sample plates with different sizes are manufactured by using a thinner plate. The flat surfaces of the plates face outwards, the grooves face inwards, and then the plates are welded into the four walls of the middle box body. The welding is carried out on the inner side surfaces of the four walls of the middle box body. The purpose is, on the one hand, to guarantee that intensity and surface are level and smooth, in addition has also saved a little steel. Meanwhile, a plurality of plate grooves on the inner wall also provide places for placing heat insulation materials.

The diameter D3 of the cloth bag is larger than the diameters D1 and D2 of the upper short pipe and the lower short pipe, so that the filtering area of the cloth bag is enlarged.

The unpowered ash removal bag-type dust collector can be used under negative pressure or positive pressure, and the cross section of the bag can be naturally (supported) to be round.

The unpowered ash removal bag-type dust collector is not provided with a bag framework. This saves many materials and manual work, has also made things convenient for the change of sack.

The above disclosure is only a preferred embodiment of the present invention, and certainly should not be taken as limiting the scope of the invention, which is defined by the claims and their equivalents.
