Abstract
The utility model discloses a bag cage for a pulse jet bag filter, which comprises a bag cage framework, wherein the bag cage framework comprises transverse bars and vertical bars; the bottom end of the bag cage framework is provided with a close cover, the top cover of the bag cage framework is provided with a tubular bag cage cap, one end of the tubular bag cage cap extends into the bag cage framework, one opening of the tubular bag cage cap is provided with a flanging, the flanging is pressed on the opening of the bag cage framework, and the middle part of the tubular bag cage cap is provided with a cone-shaped section. The utility model is simple in structure, is convenient to install and use, through the design of tubular bag cage cap and the close cover, thus preventing the air flow from scouring the part of the bag opening of a filter bag, simultaneously enhancing the injection of deashing air flow so as to increase deashing effect, avoiding the damage of the bottom of the filter bag caused by the direct scouring of overhigh pressure, and improving the service life of the filter bag.
Description
Technical field
The utility model relates generally to a kind of industrial dust suction pulse jet bag type dust collector; relate in particular to a kind of bag cage that is used for arteries and veins spray sack cleaner; for the filter bag in the equipment filtration system provides protective device, and the ejector action of air-flow when increasing deashing, ash-removal effect improved.
Background technology
In the prior art, the bag cage is used for supporting filter bag as the vitals of sack cleaner, to guarantee filter bag inside sufficient space is arranged; The outside of filter bag is a dusty gas; become clean gas behind the filter bag surface filtration of dusty gas by the support of bedding bag cage; enter the inner space of filter bag; make air-flow be pooled to the outlet that bag cage mouth and filter pocket mouths are combined to form by this space; by air-introduced machine the purified gas extraction is entered atmosphere; thereby realize purifying flue gas, the purpose of protection environment.Along with constantly carrying out of filtering, the dust layer of filter bag surface attachment is more and more thicker, resistance increases, the air communication filter bag will be not smooth, at this moment just need carry out deashing to filter bag, deashing is finished by injection system, air pulse bundle as deashing enters filter bag with very high speed, induce simultaneously and be several times as much as the air that sprays tolerance, allow filter bag produce rapid expansion and impact shock to the bottom, cause the dust in the filter bag outside to be shaken off, reach the filter bag ash removal purpose by sack, after deashing finishes, recover the filtration state.Because filter bag length is longer, under the effect of unconfined high velocity air bundle, on the one hand near the filter bag inner surface the filter pocket mouths is formed brute force and wash away, cause life-span of the filter bag to shorten, oversize because of filter bag on the other hand, the air-flow no show has decayed during the bottom, can not realize thorough deashing.
The utility model content
The purpose of this utility model is in order to remedy the deficiency of prior art, a kind of bag cage that is used for arteries and veins spray sack cleaner is provided, design by tubular bag cage cap, near when having solved deashing the filter pocket mouths filter bag inner surface is washed away by brute force, and life-span of the filter bag shortens, and filter bag is oversize simultaneously, the air-flow no show has decayed during the bottom, can not realize thorough deashing, the design of bottom cover is for solving air-flow when improving back pkt. cage cap, and excess pressure is directly washed away the injury that causes to the filter bag bottom.
The utility model is achieved through the following technical solutions:
A kind of bag cage that is used for arteries and veins spray sack cleaner, comprise marsupial cage skeleton, described bag cage skeleton includes horizontal bar and perpendicular muscle, it is characterized in that: the bottom of described bag cage skeleton is provided with capping, the top end cover of described bag cage skeleton is equipped with tubular bag cage cap, and tubular bag cage cap one end extend in bag cage skeleton, and the oral area of described tubular bag cage cap is provided with flanging, described flanging is withheld the oral area at bag cage skeleton, and the middle part of described tubular bag cage cap is provided with conical section.
When powerful arteries and veins sprays deashing, can produce drainage in the filter bag upper end and cause negative pressure before the utility model improves, make filter bag top deashing unclean, waste filter area, pressure is rendered as middle high, low all around in the filter bag simultaneously; Also wasted filter area (the two waste area of actual motion is suitable) though improve the back, pressure is low, high all around in the middle of being rendered as in the filter bag, makes ash-removal effect better, adds upper cover in the bottom, at the bottom of too high pressure can not be damaged to bag; But the more important thing is, the accumulation of various deviations such as dynamic error causes the blowing device deflection when having avoided blowing device that error when making and operation are installed, and the winding-up air-flow misaligns, if will cause air-flow that sack a part is directly washed away before improving, form injury; Because of error is inevitable extensively to exist, but then broad understanding to be unconfined high velocity air bundle exists the injury of sack, and improvement back pkt. cage provides protection just for this reason.
The utility model has the advantages that:
The utility model is simple in structure, easy to install, design by tubular bag cage cap and capping, prevented air-flow washing away to the filter bag opening position, the ejector action that has increased the deashing air-flow simultaneously is to strengthen ash-removal effect, avoided excess pressure directly washing away the injury that causes, the service life of having improved filter bag to the filter bag bottom.
