Abstract

The utility model discloses a cloth-bag type dust precipitator, which is provided with a case body, wherein a baffle plate is arranged in the case body and divides the case body into an upper part and a lower part; a proper amount of cylindrical frames are uniformly hung on the lower side surface of the baffle plate, an opening is respectively arranged at the upper end of each cylindrical frame, and a filtering screen is wrapped at the part of the cylindrical frames positioned in the lower case body; an air inlet communicated with a cavity of a kiln is arranged on the side wall of the lower case body; an exhaust opening communicated with a vacuum pump is arranged on the side wall of the upper case body; air-guiding pipes are arranged in the upper case body; blowing openings respectively corresponding to each opening on the baffle plate are arranged on the air-guiding pipes; the air-guiding pipes are communicated with a high-pressure air source; and a dust-collection opening is arranged at the bottom of the case body. The cloth-bag type dust precipitator has the characteristics that dust on the surface of a cloth bag can be thoroughly cleaned, the possibility of hole blockage is low, and the cloth bag can be effectively prevented from damage.

Description

Sack cleaner

Technical field

The utility model relates to a kind of novel sack cleaner, and it is used for reclaiming the dust of the flue dust that the roasting of chemical industry stove produces.

Background technology

In the chemical industry, often industrial chemicals such as breeze etc. need be carried out roasting, to make required product, in roasting process, can produce in the body of heater by gas, the high-temperature smoke that vaporous water and dust etc. are formed, if above-mentioned flue dust is directly discharging, not only can pollute environment, and the dust major part in the above-mentioned flue dust all can be recycled, directly discharging also causes a large amount of wastes of industrial chemicals, mostly adopt sack cleaner to reclaim in the prior art, its general mode of vibration that adopts will be shaken down to prevent plug-hole attached to the cloth bag surface dust of being made up of filter cloth, but this mode can cause filter cloth on the one hand and tear, very easily cause the breakage of filter cloth, in addition also can some sticky dust being not easy to shake influences recovering effect down.

Summary of the invention

The purpose of this utility model is at above-mentioned the deficiencies in the prior art, provides the dust on a kind of cloth bag surface to remove thoroughly, be difficult for plug-hole, and can protect effectively that cloth bag avoids damaging sack cleaner.

The utility model is that the technical scheme that is adopted that achieves the above object is: a kind of sack cleaner, it has a casing, be provided with dividing plate in the casing casing is divided into upper and lower two parts, evenly hang the tubular frame of suitable number on the dividing plate downside, and corresponding each tubular frame upper end has port on the dividing plate, and the part that the tubular frame is arranged in lower part box is coated with filter screen; The lower part box sidewall is provided with the air inlet that is communicated with the stove inner chamber, the upper box body sidewall is provided with the exhaust outlet that is communicated with vavuum pump, is provided with wireway in the upper box body, and corresponding each dividing plate port also is provided with blowing mouth on the wireway, above-mentioned wireway is communicated with high-pressure air source, and bottom half is a dust collecting opening.

Adopt the utility model of said structure that the following course of work can be arranged: at first to open the vavuum pump that is communicated with exhaust outlet, then form negative pressure in the casing, the interior flue dust of stove this moment can enter lower part box via the casing air inlet under the effect of negative pressure, contact with the filter screen that coats on the tubular frame, gas in the flue dust and vaporize water etc. pass filter screen and enter upper box body and discharged by exhaust outlet at last, dust in the flue dust can be bottled up by filter screen, part dust directly drops down onto dust collecting opening by filter screen, some dust can be attached to screen surface, when the dust of screen surface accumulates to a certain degree, close vavuum pump, open wireway, then high pressure gas is known from experience by the reverse tubular frame inner chamber that is blown into of the blowing mouth of wireway, will blow down attached to the dust of screen surface and drop down onto dust collecting opening.Therefore the utility model adopts the reverse gas dust of screen surface that blows off, and it is not only removed thoroughly and can not cause damage to cloth bag, has prolonged service life.

As improvement of the present utility model, above-mentioned tubular frame external diameter is slightly less than the internal diameter of dividing plate port, and can there be flange the upper end of tubular frame, is provided with sealing gasket between above-mentioned flange and dividing plate upper surface.The tubular frame can be hung on by the outer rim of its protrusion on the dividing plate, and sealing gasket can strengthen the air-tightness between upper and lower casing, prevents that flue dust from directly entering upper box body without filter screen, improves the rate of recovery.

Description of drawings

Fig. 1 is the structural representation of a kind of embodiment of the utility model;

Fig. 2 is the structural representation of tubular frame in the above-mentioned embodiment.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing:

As Fig. 1, shown in Figure 2, the utility model comprises a casing 1, middle and upper part in the casing 1 is provided with dividing plate 2, dividing plate 2 is separated into relatively independent upper box body 11 and lower part box 12 with casing, lower part box 12 bottoms are dust collecting opening 13, evenly be furnished with some tubular frames 3 in the lower part box 12, in the present embodiment, tube property frame 3 is the keel type structure, be on it, a ring 31 is respectively arranged down, 32, on, be connected as one by spaced bar shaped keel 33 between following ring, the last ring of tube property frame 3 has flange, and tube property frame 3 can be inserted on the dividing plate 2 accordingly in the port 21 by the top of dividing plate 2, thereby is hung on the dividing plate 2, between the flange of the upper surface of dividing plate 2 and tube property frame sealing gasket is set, the part burden that tubular frame 3 is in the lower part box 12 has filter screen; The air inlet 121 that has connection stove inner chamber of lower part box 12, have the exhaust outlet 111 that is communicated with vavuum pump on the upper side wall of upper box body 11, also be provided with wireway 4 in the upper box body 11, wireway 4 is communicated with high-pressure air source (as air compressor machine), has inflatable mouth 41 corresponding to each dividing plate port 21 on its body.
