Description

Smoke evacuation dedusting ventilation fan

The utility model smoke evacuation dedusting ventilation fan is widely used in smoke evacuation in tunnel, the mine, ventilation and dedusting.

China's existing smoke evacuation dust removal machine series, mainly have following shortcoming: 1) smoke discharging effect is poor, can't solve natural air resistance in the ventilating duct, long poorer apart from tunnel smoke evacuation dust removing effects, smoke exhaust pipe is thick, it is big to take up space, heavy, seam is easily leaked gas, even employing flexible pipe, stringing hangs on the wall, some adds several induced draft fans conveyings again at certain distance and also has little effect, tunnel tunnel face, the top, hole is that flue dust also can't enter predetermined smoke discharging pipe everywhere, and enter pipeline just around flue dust little by little, around tube head, form air and circle round that to rest on what discharge in the hole be not cigarette but wind to flue dust; 2) trouble is installed, sling and danger close, and all bring many inconvenience for back one step lining cutting excavation, vehicle pass-through, usually be damaged during construction, cause to interfere with each other, when meeting the loader muck removal especially, the smog that work car is discharged makes a big impact to the healthy of constructor, being forced to increases investment, and programming is slow; 3) structure design is unreasonable, does not meet the aerology principle, and main surface all adopts fan blade type to ventilate, prove that from air property and principle can not fundamentally solve the resistance of air, resistance is a principal contradiction, facts have proved, under the dark situation in tunnel, can't change ventilation condition.

The purpose of this utility model provides a kind of smoke evacuation dedusting ventilation fan, solves the problem of the difficulty of tunnel smoke evacuation for many years, reduces engineering cost, ensures that the workman is healthy.

The purpose of this utility model is achieved in that smoke evacuation dedusting ventilation fan, comprise motor, pipe, it also comprises air removal unit, filtering core device, the double leaf turbine, frame pipe car, the light plastic pipe, described pipe is a flexible pipe, described air removal unit left side links to each other with automatic clutch, the right side links to each other with filtering core device by air inlet pipe, described filtering core device links to each other with the double leaf turbine, described double leaf turbine links to each other with frame pipe car by flexible pipe, described air removal unit is made up of 4 pistons, described filtering core device is by filter shaft, liquid is arranged below, support with gauze wire cloth all around, the turbine inboard of described double leaf turbine is the sword head dummy.

The utility model compared with prior art has following advantage: 1) no matter how dark tunnel can both guarantee dust removing effects, create good construction environment, reduce engineering cost, reduce investment outlay, accelerating construction progress, assurance personnel health is not endangered, even has tied the unnecessary investment that causes since can reducing history, and the whole tunnel degree of depth and Position Design are played reference role; 2) only need increase by 2 valves just at one stroke two if any beating the air pressure gun pipeline, also be no more than 20 centimetres of diameters even smoke discharging pipe is installed, bring benign cycle to unit in charge of construction, create economic worth, smoke extract rate can bring up to 90% by original 10%.

Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.

Motor 1 is the three-phase alternating current synchronous motor; link to each other with air removal unit 4 (seeing Fig. 1 and Fig. 2) by automatic clutch 2; the top screw-driving of using all around of the shell 3 of this air removal unit 4; and also have hinge and clinching; easy access and maintenance; play things such as preventing external ballast and wound parts; with the protection main frame; have 4 pistons in the air removal unit 4; each 2 piston of the left and right sides of body; first piston intake is arranged to second, the 3rd, by the 4th piston discharge line, forces pressure to be delivered to outside the hole.The body left side is smoke pipe 5, and the right is an air inlet pipe 6.

(see that Fig. 3-Fig. 5), it is shaped as circle, the centre has filter shaft 9 to cross to filtering core device 7, there is tripod 10 fixing below, the top is the air outlet junction, and it links to each other with body right side air inlet pipe 6, is placed in the induced-draft fan lower right side, water or oil 11 are equipped with in inside, diesel oil preferably, its degree of depth is 1/3 height of filtering core device, the rotational speed that filtering core device changes with per minute 12 when work, the filtering core device outside has reduction gearing 12 to drive, and filter core equipment is placed in traverse in the filter case 8.Just be filtered device as dust and flue dust and wash, regularly open pipe gate valve 13 discharging dust below the filtering core device to one.

Reducer 14 (see figure 6)s are used for driving diesel-oil filter element device 7 and rotate, and speed is to drop to per minute 12 with per minute by 1600 original commentaries on classics to change, and mainly drives 7 cleaning actions of filtering core device and ringing, and it is made up of " fourth " word gear-box reducer and motor 15.Double leaf turbine 17 is made up of 2 elongated motor, each driven by motor turbine rotation supercharging flue dust, work to carry and reduce air resistance, strengthen the flow of air, the turbine inboard is the sword head dummy, to reduce of the mobile influence of the volume of motor own to flue dust, be filtering core device 7 services, it is connected with filter core air inlet pipe 16.Flexible pipe 19 is to be used for transmitting and the dedicated pipe of mobile smoking direction, the left side double leaf turbine 17 that links to each other, and the right link pipe car 18, its length and practicality are exceeded.Frame pipe car 18 is special handcarts that move and seek smog, it is made up of three light plastic pipes 21 and aluminum alloy square bar of therebetween, aluminium alloys plays light and handy and skeleton function, three tube heads are with netting 20 cap seal, in order to avoid inspiration particle, damage parts, three tube length are benefit with hole high 80%.It is easy to use, light and handy flexibly, all can enter conveyance conduit at flue dust in tens meters of induced-draft fans.Particularly more effective to the flue dust at tunnel tunnel face and top, hole place, this driver's handle is laid particular stress on than the front during design, is of value at any time three pipes up, and is not fragile.
