Abstract
The utility model discloses a novel totally enclosed explosion-proof valve of weight formula device relates to low pressure pulse sack buggy collector field, including the straight tube, fixed surface is connected with the articulated elements on the straight tube left end to there is the top cap through articulated elements sliding connection, fixed surface is connected with the balancing weight on the top cap opposite side, and there is the bracing piece straight tube left end lower surface through articulated elements sliding connection, and the contact links to each other under upper end of the support bar and the top cap left side. The utility model discloses taking place the accident when low pressure pulse sack buggy collector operation in-process, because the too high explosion-proof valve of internal pressure explodes, it explodes to let out the aluminum sheet and explodes to open and break, under the influence of the inside impact air current of equipment, the top cap seals explosion-proof mouthful at once under the effect of balancing weight gravity, because install seal ring on the top cap, ensure the tight explosion-proof mouthful of sealing of top cap, prevent that the outside air from getting into low pressure pulse sack buggy collector through the straight tube, thereby the leakproofness and the security of equipment have been guaranteed.
Description
Technical Field
The utility model relates to a low pressure pulse sack buggy collector field specifically is a novel totally enclosed explosion-proof valve device of weight formula.
Background
Coal injection equipment bag in coal injection workshop at presentThe coal dust collecting device comprises a raw coal bin, a coal feeding bin, a coal mill, a heating furnace, a cloth bag coal dust collector, a coal discharging pipe, a wood chip separator, a coal dust bin, a powder discharging fan, a blowing tank, a blowing pipeline and the like, coal dust collected by the cloth bag coal dust collector falls into a cone hopper of the coal dust collector, the coal dust is stored in the coal dust bin through a star-shaped ash discharging valve and the wood chip separator, the coal dust collector is used for carrying out gas-solid separation on a gas-powder mixture, and the concentration of the gas-powder mixture at the inlet of the coal dust collector is basically less than 1000g/Nm3The concentration of the filtered gas outlet is less than 30mg/Nm3。
In the low pressure pulse sack pulverized coal collector of present operation, because the dust of collecting is the buggy, for the security of assurance equipment, must set up explosion-proof valve in low pressure pulse sack pulverized coal collector box both sides, what adopt at present usually is integrated configuration such as straight tube, flange and aluminum sheet, this kind of structure is in case because the explosion-proof valve of accident bursts, whole explosion-proof valve is in open state, a large amount of air is inhaled in the collector, thereby cause collector internal accident aggravation, must shut down the processing, cause serious damage for whole equipment operation system.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a novel weight formula totally enclosed explosion-proof valve device to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme:
the utility model provides a novel totally enclosed explosion-proof valve of weight formula device, includes the straight tube, fixed surface is connected with the articulated elements on the straight tube left end to there is the top cap through articulated elements sliding connection, fixed surface is connected with the balancing weight on the top cap opposite side, and straight tube left end lower surface has the bracing piece through articulated elements sliding connection, and the upper end of the support bar links to each other with top cap left side lower surface contact.
As a further aspect of the present invention: the left end of the straight pipe is fixedly connected with a low-pressure pulse cloth bag pulverized coal collector.
As a further aspect of the present invention: and an explosion venting aluminum sheet is fixedly arranged inside the left side of the straight pipe.
As a further aspect of the present invention: the end opening at the left end of the straight pipe is provided with an explosion-proof opening, and the explosion-proof opening is in butt joint with the top cover.
As a further aspect of the present invention: and a sealing gasket is fixedly arranged on the lower surface of the top cover.
Compared with the prior art, the beneficial effects of the utility model are that: this novel weight formula totally enclosed explosion-proof valve device, when the low pressure pulse sack pulverized coal collector in-process emergence accident, because the explosion-proof valve that internal pressure is too high bursts open, it bursts open and breaks to let out the explosion-proof aluminum sheet, under the influence of the inside impact air current of equipment, the top cap seals explosion-proof mouthful at once under the effect of balancing weight gravity, because install seal ring on the top cap, ensure the tight explosion-proof mouth that seals of top cap, prevent that the outside air from passing through the straight tube and getting into in the low pressure pulse sack pulverized coal collector, thereby the leakproofness and the security of equipment have been guaranteed.
Drawings
Fig. 1 is a structural schematic diagram of a novel weight type fully-closed explosion-proof valve device.
In the figure: 1-explosion venting aluminum sheet, 2-top cover, 3-balancing weight, 4-explosion-proof opening, 5-sealing washer, 6-straight tube, 7-low pressure pulse cloth bag coal dust collector.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Example one
Referring to fig. 1, a novel weight type fully-closed explosion-proof valve device comprises a straight pipe 6, wherein the upper surface of the left end of the straight pipe 6 is fixedly connected with a hinged piece, and the hinged piece is connected with a top cover 2 in a sliding manner.
Particularly, fixed surface is connected with balancing weight 3 on 2 opposite sides of top cap to 6 left ends lower surfaces of straight tube have the bracing piece through articulated elements sliding connection, and the upper end of the bracing piece links to each other with 2 left side lower surface contact of top cap, 6 left ends of straight tube fixedly connected with low pressure pulse sack buggy collector 7, 6 left inside fixed mounting in straight tube have explosion venting aluminum sheet 1, 6 left end ports of straight tube are equipped with explosion-proof mouth 4, dock each other between explosion-proof mouth 4 and the top cap 2.
Example two
Referring to fig. 1, the difference between the second embodiment and the first embodiment is that a sealing washer 5 is fixedly installed on the lower surface of the top cover 2, and the top cover 2 is ensured to tightly seal the explosion-proof opening 4 by installing the sealing washer 5, so that external air is prevented from entering the low-pressure pulse bag coal dust collector through a straight pipe 6, and the low-pressure pulse bag coal dust collector is well protected.
This novel weight formula totally enclosed explosion-proof valve device, take place the accident when 7 operation in-process of low pressure pulse sack pulverized coal collector, because the explosion-proof valve that internal pressure is too high explodes out, let out and explode aluminum sheet 1 and explode and break, under the influence of the inside impact air current of equipment, top cap 2 seals explosion-proof opening 4 at once under the effect of 3 gravity of balancing weight, because install seal ring 5 on top cap 2, ensure 2 tight explosion-proof openings 4 of top cap, prevent that the outside air from passing through in 6 entering low pressure pulse sack pulverized coal collector 7 of straight tube, thereby the tightness and the security of equipment have been guaranteed.
