Abstract
The invention relates to a filter bag protection device for a pulse jetting bag type dust remover, which comprises a sleeve pipe, a support frame and a fixed ring, wherein the outer wall of the fixed ring is abutted against the inner wall of a cage mouth of a bag cage, and the upper end of the fixed ring is connected with the lower end of the support frame; the lower end of the support frame is arranged on the cage mouth of the bag cage, and the upper end of the support frame is connected with the upper end of the sleeve pipe; and the lower end of the sleeve pipe is arranged in the bag cage. The invention has the advantages of low investment and simple and convenient installation, and the purposes of protecting the filter bag and improving jetting effect can be achieved by only fixing the device on the top ring of the original bag cage without replacing the original bag cage of the filter bag.
Description
Technical field
The present invention relates to a kind of filter bag protective device that is used for pulse blowing bag type dust precipitator, belong to sack cleaner corollary apparatus technical field.
Background technology
Existing sack cleaner adopts the pulse of compressed air purge mode mostly, adopts compressed air to induce purification back air-flow to spray into filter bag, makes filter bag generation vibration, gas shock dust layer reach ash-removal effect.But; filter bag adopts support pouches cage in the open type in the existing design, and the sack position does not have safeguard measure, easily causes the winding-up air-flow to blow out the strong filter bag zone filtrate damage of effect; long duration of action can make this part filter bag zone hole occur, causes sack cleaner dust removing effects severe exacerbation.
As shown in Figure 1, the open type bag basket structure schematic diagram of using for existing filter bag inner support.In order to address this problem, except that new design bag cage, existing open type bag cage is installed additional this protective device on the import position, can effectively protect filter bag directly not to be subjected to the air-flow effect, reach the purpose that improves the air flow blowing effect, prolongs life-span of the filter bag.
Summary of the invention
Technical problem to be solved by this invention provides the filter bag protective device that is used for pulse blowing bag type dust precipitator, on the basis of not changing bag cage, reaches the purpose of protection filter bag opening, and gas-flow resistance is little when filtering work, simple installation.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: a kind of filter bag protective device that is used for pulse blowing bag type dust precipitator is provided; comprise sleeve pipe, bracing frame and retainer plate; the outer wall of retainer plate is near the cage mouth inwall of bag cage; the upper end of retainer plate connects the lower end of bracing frame; the lower end of bracing frame is located on the cage mouth of bag cage; the upper end of the upper end joint sleeve of bracing frame, the lower end of sleeve pipe is located in bag cage.
Further, described sleeve pipe is a hourglass shape.
Advantage of the present invention is: need not to change original filter bag bag cage, only need be fixed on the collar of former bag cage, just can reach the purpose of protection filter bag, raising winding-up effect, have small investment, the easy-to-install characteristics.

The specific embodiment
Further specify the present invention below in conjunction with drawings and Examples.
Embodiment
As shown in Figure 2; for having the pulse blowing bag type dust precipitator structural representation of filter bag protective device; as shown in Figure 3; be filter bag protective device vertical view; Fig. 4 is the profile along A-A line among Fig. 3; the described filter bag protective device that is used for pulse blowing bag type dust precipitator is made up of sleeve pipe 1, bracing frame 2 and retainer plate 3; the diameter of described retainer plate 3 is slightly less than the diameter of bag cage 4; the outer wall of retainer plate 3 is near the cage mouth inwall of bag cage 4; thereby guarantee that sleeve pipe 1 keeps vertically fixing state, also can use reinforcings such as metal-to-metal adhesive simultaneously.The upper end of retainer plate 3 connects the lower end of bracing frame 2, and the lower end of bracing frame 2 is located on the cage mouth of bag cage 4, the upper end of the upper end joint sleeve 1 of bracing frame 2, and 3 of sleeve pipe 1 and retainer plates have gas channel, and described sleeve pipe 1 is a hourglass shape.Described sleeve pipe 1 passes described retainer plate 3 and bag cage 4 under the support of described bracing frame 2, the lower end of sleeve pipe 1 is located in bag cage 4.
Frame of the present invention is contained on the cage mouth of bag cage, when carrying out deashing work, as shown in Figure 5, is deashing fundamental diagram of the present invention.The winding-up air-flow sprays into sleeve pipe 1, and simultaneously the inducing peripheral air gas channel that passes bracing frame 2 and sleeve pipe 1 and 3 of retainer plates forms induced draft, compares with the bag cage that protective device is not housed, and can effectively protect the sack of filter bag, the prolongation life-span of the filter bag.When the work of filtration, as shown in Figure 6, be filtration fundamental diagram of the present invention, purifying gas flow enters the pure qi (oxygen) casing simultaneously inside and outside sleeve pipe 1, compare with the bag cage that does not install the casing protection device additional, and the resistance of air-flow is little.In addition, the present invention need not to change former marsupial cage, small investment, simple installation.
