Description

A kind of flue fire prevention cleaning plant of no work blind spot

Technical field

A kind of flue fire prevention cleaning plant of no work blind spot, belongs to flue cleaning equipment technical field.

Background technology

Flue is the channel of exhaust gas and smog emission, and dining room would generally set flue, and the flue in dining room is mostly longer and narrower, So as to facilitate the discharge of oil smoke, since the oil in oil smoke can be attached in flue inner wall, after long-time use, flue inner wall can be attached More oil, is become narrow gradually so as to cause flue, since the vertical height of flue is larger and long and narrow, and in order to facilitate flue It installation and uses, the both ends of flue would generally be bent to close to the direction in dining room, and manual cleaning is often merely able to clean flues two End, and can not be cleaned in the middle part of flue, this results in flue middle part more and more narrow, hinders the ventilation of flue, affects oil smoke Discharge, and since oil smoke is adhered to flue inner wall, the open fire in flue is easy to cause fire, and there are security risks.

Invention content

The technical problems to be solved in the utility model is：One kind is overcome the deficiencies of the prior art and provide to glue by powder of preventing fires The flue without work blind spot that brush roll clears up flue inner wall is attached on pasta, open fire is avoided to cause fire and pass through to prevent fires Cleaning plant.

Technical solution is used by the utility model solves its technical problem：The flue fire prevention cleaning without work blind spot Device, it is characterised in that：Including being arranged on the baffle at flue both ends and dry powder nozzle, baffle is detachably arranged in flue two It holds and flue is closed at both ends, at least side of flue is provided with the mouth that dusts, and dry powder nozzle is arranged on the outside of the mouth that dusts, dry powder spray Head is connected with powder inlet pipe；Brush roll is additionally provided in flue, brush roll is mounted in walking mechanism.

Preferably, the dry powder nozzle is connected by telescopic sleeve pipe with powder inlet pipe, and set is arranged with outside telescopic sleeve pipe Pipe resetting spring, the both ends of casing resetting spring are connected with the both ends of telescopic sleeve pipe and telescopic sleeve pipe are driven to shrink respectively.

Preferably, the brush roll is rotatably installed in by installation axle in walking mechanism, brush roll inner wall and installation axle interval Setting is arranged at intervals with multiple blades, and the inner end of blade is tilted along the circumferential direction of brush roll to the same side, peace around brush roll inner wall The cylinder that axis is one end closing is filled, the side of installation axle is provided with through-hole.

Preferably, the side of the brush roll is arranged at intervals with multiple spray holes.

Preferably, the inner end of the spray hole is identical with the inner end inclined direction of blade.

Preferably, the brush roll is axially slidable installs on the mounting shaft, and brush roll endoporus lower end is from the bottom to top The taper that diameter is gradually reduced is equipped with position-arresting disk, and be encircled into conical cavity with brush roll lower end in the installation axle on the downside of brush roll, brushes The upper end of roller and installation axle sealed set.

Preferably, the outer wall of the brush roll is equipped with long brush hairs and short bristles, and long brush hairs and short bristles are along the half of brush roll Diameter direction is set.

Compared with prior art, advantageous effect possessed by the utility model is：

1st, this flue fire prevention cleaning plant without work blind spot makes dry powder nozzle that the mouth that dusts be passed through to enter inside flue, So as to spray into fire prevention powder to flue inside, fire prevention powder can be attached on the pasta of walling of flue after entering flue, and brush roll can be to whole A flue inner wall is cleared up, and flue inner wall is avoided to be attached with oil, both ensure that the ventilatory effect of flue, so as to make pasta and cigarette Air exclusion in road even if open fire is generated in flue will not cause fire, greatly reduces fire odds, reduces The danger of fire occurs in flue, reduces security risk, there is no the dead angles of fire prevention and cleaning.

2nd, telescopic sleeve pipe can extend under the action of powder inlet pipe pressure, so as to which dry powder nozzle be made to stretch into flue, treat into When pressure in tube cell stops, telescopic sleeve pipe shrinks telescopic sleeve pipe under the elastic force effect of casing resetting spring, and then Reset dry powder nozzle.

3rd, cleaning solution is injected to by the through-hole of installation axle in brush roll, and brush roll is pushed to rotate by blade, without The rotation of brush roll can be realized by power plant module driving, made device structure simple, do not needed to setting transmission mechanism.

4th, brush roll outer wall is equipped with spray hole, can spray into cleaning solution in flue and wash away the oil in flue or cigarette ash, Cleaning is thorough；The inner end of spray hole is identical with the inclined direction of blade inner end, so as to not only realize sprinkling cleaning solution, but also realize Auxiliary drive brush roll rotates.

5th, brush roll lower end and position-arresting disk are encircled into conical cavity, when cleaning solution sprays into conical cavity, due to cleaning fluid pressure Effect, brush roll are moved up along installation axle, and brush roll lower end is detached with position-arresting disk at this time, and the pressure in conical cavity reduces, brush roll edge Installation axle moves down, it is achieved thereby that the axial wobble of brush roll, forms relative motion, cleaning effect is good with walling of flue.
