Abstract
The utility model discloses a low-pressure pulse bag type dust collector, which comprises an upper box body, a middle box body and a lower box body, wherein the box bodies are communicated with each other. A filter bag and an off-line valve box are arranged in the middle box, and a single-chamber blowing air bag is arranged in the upper box body. The low-pressure pulse bag type dust collector is characterized by further comprising a push-up type off-line valve which is fixed in the off-line valve box through a separating board, and the push-up type off-line valve comprises an air cylinder and an off-line valve board fixed at the front end of a cylinder rod of the air cylinder. The low-pressure pulse bag type dust collector is simple in structure, better in work adaptability, not limited by air sources in working and higher in safety.
Description
Technical field
The utility model relates to a kind of action of low-voltage pulse bag dust filter, and pushing-type Low-Pressure Pulse Bag Filter on especially a kind of off-line valve is widely used in fields such as metallurgy, chemical industry and electric power.
Background technology
At present, the action of low-voltage pulse bag dust filter is than indispensable part at the off-line valve in service of going into operation, and is convenient to control the air-out of each filter chamber and the off-line maintenance of equipment.In traditional Low-Pressure Pulse Bag Filter, the off-line valve is roof-mounted.If the air source of the gas that the fruit deduster happens suddenly at work is not enough or interruption, the off-line valve plate of off-line valve can not satisfy under the situation of use in the source of the gas supply, because the slow sedimentation of self gravitation effect meeting of valve plate all is in closed condition until filter chamber's off-line equipment, this moment, the negative pressure of deduster sharply increased, impact for the air draught and the deduster shell structure of each dust sucting point, even scrap behind the deduster gross distortion.
The utility model content
The technical problems to be solved in the utility model provides a kind of simple in structure, better impulse bag dirt catcher of labor aptitude.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of Low-Pressure Pulse Bag Filter, it comprises upper box, middle casing, lower box, be communicated with between each casing, be provided with filter bag and off-line clack box in the middle casing, be provided with single chamber winding-up gas bag in the upper box, its key technology is: also comprise by dividing plate and be fixed in last pushing-type off-line valve in the off-line clack box, described on the pushing-type off-line valve off-line valve plate that comprises cylinder and be fixed in cylinder cylinder bar front end.
Above-mentioned off-line valve plate is a circular configuration, is provided with reinforcement on the off-line valve plate.
Adopt the beneficial effect that technique scheme produced to be: the last pushing-type off-line valve in the utility model adopts cylinder direct pull off-line valve plate, the open and close of valve opening are satisfied in the pushing-type work on carrying out under the pulling of cylinder of last pushing-type off-line valve, under the situation of air source of the gas deficiency that happens suddenly or interruption, last pushing-type off-line valve can automatically reset, make pushing-type off-line valve be in normally open, not limited by source of the gas.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Participate in accompanying drawing 1, accompanying drawing 2 and accompanying drawing 3, the utility model comprises upper box 4, middle casing 3, lower box 1, be communicated with between each casing, be provided with filter bag and off-line clack box 9 in the middle casing 4, be provided with single chamber winding-up gas bag 7 in the upper box 4, it also comprises by dividing plate 26 and is fixed in last pushing-type off-line valve in the off-line clack box 9, described on the pushing-type off-line valve off-line valve plate 19 that comprises cylinder 20 and be fixed in cylinder 20 cylinder bar front ends.The described pushing-type off-line valve of going up is in the middle of the net air turnover air channel 10, and off-line valve plate 19 is positioned at the upper position of off-line clack box 9, and is fixed in the cylinder bar front end of cylinder 20 by nut and locking plate.The repair and maintenance of off-line valve plate 19 and cylinder 20 etc. is provided with special access path 21.
Described off-line valve plate 19 is a circular configuration, on off-line valve plate 19, be provided with reinforcement 25, off-line valve plate 19 general employing thickness are the Q235A material of 8～14 ㎜, according to the reinforcement setting that the specification and the material thickness of off-line valve plate 19 are determined upper surface, satisfy its requirement of strength.
The utility model is the passing away of net air behind the deduster clarifying smoke, is the off-line ash-clearing of each filter chamber of deduster and the gauge tap of off-line maintenance simultaneously.When certain filter chamber being carried out deashing or maintenance, the off-line valve of this filter chamber is in closed condition and works offline, after finishing when working offline, the off-line valve of this filter chamber is in opening and carries out conventional udst separation work, during another filter chamber is in again and works offline, in the dust pelletizing system, the work of off-line valve proceeds to last filter chamber one by one and finishes, at last a work period.
Open and close of the present utility model are to supply with by successive source of the gas to carry out circulating work.If the situation of source of the gas undersupply or interruption takes place, the structure of pushing-type has been given full play to effect on the off-line valve, the off-line valve plate of closing can fall automatically, make the air-out of each filter chamber be in opening, the in service of dust pelletizing system the negative pressure puberty of deduster itself is changed, thereby guaranteed the influence that is not subjected to source of the gas in the case that is operated in of deduster, the reliable assurance that the dedusting of each production line airborne dust point is provided, and provide the time facility to the maintenance of supplying with source of the gas.
