Abstract

The utility model discloses an autorotation spraying device, which adopts the technical scheme that 2-3 pipe-type spokes are connected onto an annular water pipe; the other end of each pipe-type spoke is connected onto a shaft sleeve; a hollow shaft head is fixed on an elbow of a water supply stand pipe; the shaft sleeve is sleeved on the hollow shaft head; a water channel, through which the annular water pipe is communicated with the water supply pipe, is arranged on the pipe-type spokes, the shaft sleeve and the hollow shaft head; several nozzles are installed on the annular water pipe; the spraying directions of the nozzles guarantee that water mist covers a cross section of a laneway during the rotation of the annular water pipe. The autorotation spraying device provided by the utility model takes full advantages of reverse impact force of spraying, guarantees the atomizing effect of dust-proof water, and enlarges the covering area of spraying.

Description

Automatic rotary atomization device

Technical field

The utility model relates to a kind of automatic rotary atomization device, especially a kind of getting working face and transportation transfer point atomizing de-dusting apparatus of being applicable to.

Background technology

In recent years, along with the continuous upgrading that improves constantly and exploit equipment of pit mining level, combined to adopt to combine pick no matter be; Still auxiliary fortune coal facility; The capital produces a large amount of dust, if protect untimelyly, not thorough, directly the constructor is caused; The site operation personnel of special driving face; Work long hours and producing the dirt place,, site operation personnel and the related personnel's of native system healthy meeting is caused serious harm if dust-laying effect is poor, the protection is not in place, dust prevention can not get implementing; In order to solve dust problem, atomization mechanism is all installed in the down-hole, but receives the restriction of shower nozzle size, and the spraying area is limited, and only fixing direction spraying, catches the dirt weak effect.

Summary of the invention

In order to solve the above-mentioned deficiency of existing atomization mechanism, the utility model provides a kind of automatic rotary atomization device, thereby enlarges the spraying area.

For addressing the above problem, the technical scheme that the utility model is taked is: it is on an annular conduit, to connect 2-3 root tubular type spoke, and the tubular type spoke other end is connected on the axle sleeve; Fixing hollow shaft head on water supply standpipe elbow, axle sleeve is enclosed within on the hollow shaft head, and tubular type spoke, axle sleeve and hollow shaft head are provided with the water channel that annular conduit is communicated with feed pipe; On annular conduit, install several shower nozzles, spray water covered drift section when the spraying to of shower nozzle should guarantee the annular conduit rotation.

During spraying, water under high pressure passes through spindle nose.Axle sleeve and tubular type spoke get into annular conduit, spray at a high speed through shower nozzle, utilize the recoil strength of water under high pressure that rotary atomization device is run up, and make vaporific high-speed jet cover drift section, reach the purpose of automatic rotary atomization device depositing dust.

Through in production practices, verifying, do not use before this automatic rotary atomization device, the boring head work plane is in fully-mechanized digging machine cutting units rotation cutting process; The dust dust reduction rate less than 75% of producing; After using automatic rotary atomization device, dust reduction rate reaches more than 90%, facts have proved that each boring head work plane increases dustproof water pressure and reaches 5MPa, installs more than 3 groups; Use automatic matching device in dustproof water, to add the depositing dust agent simultaneously, dust reduction rate can reach more than 95%.This device is easy to use, safe; Use in this device work constructor, equipment damage fewly, guarantee that the site operation personnel avoid the harm of dust, make the site operation personnel that a good line-of-sight circumstances arranged; Be convenient to normal operations, the construction safety reliability is strengthened.

The characteristics that the utlity model has:

1, through using the utility model, made full use of the anti-force of spraying, guaranteed the atomizing effect of dustproof water, increased the spraying area coverage.

2, special rotary spraying design is sprayed spraying ringwise, has increased the area coverage of spraying, effectively reduces mine dust and flies upward diffusion, has strengthened dust-laying effect.

3, the utility model is simple in structure, and processing and fabricating is convenient, and solid and reliable, dust-laying effect is good.

In getting working face and transportation transfer point atomizing de-dusting technical field; Everyly include similar rotary spray structure, with the reaction force driven rotary of spraying, to the atomization mechanism of dustproof dust-laying effect all in the protection domain of the utility model.
