Description
Technical field
The utility model relates to a kind of vacuum dust sucking device that is used to the filter bag in the sack cleaner to carry out inner dedusting.
Background technology
Sack cleaner is the equipment that dust and dust are separated from flue gas, and it is widely used in the dedusting of industries such as thermal power generation, casting, waste incineration, cement, mining.Because improving constantly of national requirements for environmental protection, the positive large tracts of land of old-fashioned in the market electric cleaner is replaced by sack cleaner, as shown in Figure 3, the flue gas that contains dust and dust enters the visceral-qi chamber 17 of deduster inner sealing card 20 bottoms from air inlet 16, there are a plurality of 2～10 meters long filter bags 18 inside of deduster, its material is natural fiber, chemical synthetic fiber, glass fibre or metallic fiber etc., has cage bone 19 to support in the filter bag 18.The top of deduster has one deck sealing card 20 to prevent the leakage of flue gas, the top of filter bag is the filter pocket mouths 21 of passing sealing card 20, filter pocket mouths 21 is connected with discharge duct 27 by sealing card 20 top air-purifying chambers 24, flue gas sees through the inside that filter bag 18 enters filter bag after entering the inside of deduster, dust and dust are blocked in the outside of filter bag, gas after the filtration enters gas channel by the passway, reaches the effect that purifies flue gas.After the long-term use of deduster, filter bag is outside can to accumulate a thick layer of ash, can influence the filtration and the service life of filter bag, the part deduster self has the pulsed pneumatic shuttle, can from high pressure gas bag 22, import winding-up pipe 25 to the gas of high pressure by pulse valve 23, injection hole 26 from cloth bag oral area top sprays into filter bag at last, make filter bag 18 be subjected to gas impact and with the intermittent collision of the cage ostosis of inside, allow filter bag in shake, outside dust shake be dropped into into dust collector ash hopper 28, reach certain dedusting effect.
Filter bag 18 in use inevitable with bag in cage bone 19 and deduster internals to collision friction, collision friction can make filter bag produce local damage for a long time.Dust will pass broken hole and arrive sealing card 20 tops in the flue gas, and part enters atmosphere with flue gas, and part is at the card surface settlement, and the final overwhelming majority enters filter bag 18 inside, and is serious even fill up whole filter bag.Cause the local of filter bag strainability or completely lose.The dismounting and change work of filter bag also becomes difficult.
The utility model content
For the filter bag that solves in the existing deduster is full of dust, cause reducing the filterability of filter bag and the problem that can't dismantle, the utility model provides following technical scheme:
A kind of vacuum dust sucking device, it comprises compressed air hose, be connected in the air chamber of described compressed air hose by air valve, be fixedly connected on the gas blow pipe of described air chamber, be fixedly connected on the air intake duct of described air chamber, the ash discharge flexible pipe that is connected with described gas blow pipe by first joint, be connected in the suction ash flexible pipe of described air intake duct and the broken ash pipe of stainless steel that is connected in the grey flexible pipe of described suction by the 3rd joint by second joint, be provided with I shape break-in ring in the described air chamber, described I shape break-in ring and described air chamber inwall form a ring-type air chamber, have a plurality of spray-holes on the sidewall of ring-type air chamber, described spray-hole is right against gas blow pipe, and the end of the broken ash pipe of described stainless steel offers a plurality of passages.
More excellent is that described air valve is provided with switch knob.
The utility model advantage is:
1, simple and practical, operate simple and easy, easy to maintenance;
2, power source is a compressed air, can adjust power according to actual conditions;
3, cleaning effect is good, and speed is fast, has effectively improved the result of use and the service life of sack cleaner, has very positive meaning.

The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby protection domain of the present utility model is made more explicit defining so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that.
Shown in accompanying drawing 1 the utility model structural representation and accompanying drawing 2 the utility model air chamber part-structure schematic diagrames, compressed air hose 1 is connected with air chamber 4 by the air valve 2 that has switch knob 3.Air chamber 4 inside are provided with an I shape break-in ring 5, and I shape break-in ring 5 outsides form a ring-type air chamber with air chamber 4 inwalls, and this ring-type air chamber communicates with gas blow pipe 7 by a plurality of spray-holes 6 on air chamber 4 sidewalls.I shape break-in ring 5 internal paths communicate with gas blow pipe 7 and air intake duct 8 respectively.Gas blow pipe 7 is connected with ash releasing tube 10 by first joint 9; Air intake duct 8 is connected with the grey flexible pipe 12 of suction by second joint 11; Inhaling grey flexible pipe is connected by the broken ash pipe 14 of the 3rd joint 13 and stainless steel.Broken ash pipe 14 other ends of stainless steel are the end that offers a plurality of passages 15.Ash discharge flexible pipe 10 and the grey flexible pipe 12 of suction can be chosen suitable length according to actual conditions.
The utility model is by the air force jet current principle, working media is a compressed air, compressed air process compressed air hose 1 enters the ring-type air chamber in the air chamber 4, change airflow direction through I shape break-in ring 5, compressed air by spray-hole 6 along gas blow pipe 7 high velocity jet forward, thereby in air intake duct 8, form and reach as high as the negative pressure of 33kPa, thereby realize the function of quick dust suction; The end of the broken ash pipe 14 of stainless steel can be with the dust fragmentation of caking simultaneously.
As shown in Figure 4, earlier at filter bag of sack cleaner dismounting, expose a card hole during use, ash releasing tube is stretched into this card hole; Compressed air is connected by compressed air hose; The filter pocket mouth that broken ash pipe of stainless steel and the grey flexible pipe of suction are handled from needs extend into the bottom; The rotary switch spanner is opened the defeated dirt of beginning dust suction with air valve; Dust in the filter bag is picked up, and directly delivers in the ash bucket of sack cleaner card below.
The above; it only is the specific embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; any those of ordinary skill in the art are in the disclosed technical scope of the utility model; variation or the replacement that can expect without creative work all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
