Description

Mine road surface dust removal car

The technical field is as follows:

this product relates to the road surface clearance field, specifically is a rely on the fan to induced draft and blow to accomplish the dust pelletizing system of road surface clearance operation at road surface dust removal in-process, and the road surface dust removal in specially adapted mine.

The background art comprises the following steps:

the mine road is built for the mine vehicle to pass through, because the surrounding environment dust, coal dust, smoke and dust are great and the rubble is more, and the road surface deposition is serious, and the vehicle back of traveling raises a large amount of dust and seriously influences the back car sight, causes the potential safety hazard, needs in time to carry out the deashing to the road surface, therefore it is very necessary to study a mine road surface cleaning device of high-efficient dust removal.

The common dust removing vehicles include a sweeping vehicle, a washing and sweeping vehicle and a dust collecting vehicle.

When the sweeping machine works, the side brushes at the bottom of the sweeping machine sweep garbage at corners to a cleaning range of the main brush from outside to inside in a centralized manner, and the main brush sweeps the garbage to the front of the sucking disc; the garbage is continuously sucked into the garbage can through the sucking disc, and the filtering system filters the sucked dust-containing airflow and then discharges clean air to the atmosphere.

The road surface is cleaned once through high-pressure spraying equipment during the operation of the sweeper, then the cleaned road surface is cleaned through a high-speed turntable brush, and finally the cleaned garbage is sucked into the garbage can through a middle-arranged or rear-arranged negative pressure sucker.

The common dust collection vehicle has the same working principle as a dust collector, utilizes the power generated by a centrifugal fan to generate negative pressure in a box body, generates pressure difference with the outside of the box body, generates suction force by utilizing the pressure difference, and transmits the suction force to a dust hood along a pipeline, the dust hood sucks dust from the ground, the collected dust-containing airflow is treated by a filtering system, the dust is left in the box body, and clean air is discharged to the atmosphere.

To the mine road surface, if adopt traditional sweeping machine, when the operation, the rotatory brush of vehicle bottom can be raised the dust on ground to all around, is difficult to be taken sucking disc the place ahead along the brush, and sweeping machine not only cleans the effect limitedly, but also can increase the dust content in the air on the contrary to be not applicable to the mining site road surface. For example: the invention name is as follows: a sweeping mechanism for a sweeper truck is disclosed in the application number: 201921873626.8, which is suitable for cleaning up refuse on urban pavements, it has a very limited effect in the face of dust on mine pavements.

To the mine road surface, if adopt the washing and sweeping vehicle, the dust on ground can be drenched and flow to low relief department under the effect of rivers to the high pressure rivers of washing and sweeping vehicle spun, and the while rivers of spun still can cause the mire on mine ground road surface to be unfavorable for the current of follow-up vehicle, and the washing and sweeping vehicle is equally unsuitable mine ground road surface, for example: the invention name is as follows: a road ground dust removal vehicle, application number: 202021478029.8, it is mainly directed at level highway road surface, and the deposition is less, and for mine road surface, because dust and coal ash are more, its rivers that spout can wet the dust on ground and form the mud piece and be difficult to be swept away, remain on the road surface and influence follow-up traffic.

Although the road surface of the mine field mainly comprises dust and powder, the dust collection vehicle is most suitable, if the traditional pure suction type vacuum dust collection vehicle is adopted, the road surface of the mine field is often rugged and uneven, the dust and the powder between broken stone thin seams are difficult to clean efficiently only by suction, the dust collection capacity of the dust collection vehicle is closely related to the ground clearance of the dust collection cover, the ground clearance is too high, the suction force is reduced, the ground clearance is too low, the risk that the dust collection cover is scratched on the mine road surface is increased, and the damage of the dust collection cover is easily caused.

Because the big and in the road surface unevenness of mine mountain road dust volume, the rubble slit dust be difficult to high-efficient clearance, prior art all can't reach the cleaning performance of ideal, the utility model discloses to the rugged and uneven road surface of mining site create a blow-and-suck type dirty-suction vehicle, compensatied the not enough of current dirty-suction vehicle dust removal.

The utility model has the following contents:

in order to achieve the purpose, the utility model provides a mine road surface dust removal car mainly comprises automobile body, air curtain generating device, raise dust device, dust purification device.

Air curtain generating device includes four at least air supply columns just four at least air supply columns are cyclic annular interval arrangement, every along circumference the air supply column all is connected with the fan, and the periphery wall of air supply column is equipped with the air outlet that extends along length direction, and four at least air supply columns can form the air curtain that seals the encirclement all around through respective air outlet.

The raise dust device includes raise dust dryer and fan, and the axial of raise dust dryer is installed in the below of automobile body, and the periphery wall of raise dust dryer is equipped with along axially extended air outlet, and the fan is connected with the raise dust dryer, provides wind-force to the raise dust dryer, and the wind that the air outlet was derived can blow the dust in ground and the slot.

The dust purification device comprises a dust hood, a fan, an air pipe, a dust remover and a dust collection barrel, wherein the dust hood is positioned above an air curtain which is formed by an air curtain generation device and is surrounded by the air curtain, the upper part of the dust hood is connected with the dust remover through the air pipe, a dust outlet below the dust remover is connected with the dust collection barrel through a buckle, and an air outlet above the dust remover is connected with the fan through the air pipe.

This mine road surface dust removal car during operation, the wind-force that the fan among the raise dust device provided comes out through the air outlet of raise dust dryer, blow up the dust in the especially eave tile of ground, because air curtain generating device can form the air curtain that seals all around and encircle, thereby the dust control that will raise is inside the air curtain, fan among the dust purification device provides the draft force to the suction hood through the tuber pipe, thereby make the suction hood below form the negative pressure, the dust gas that is raised passes through the tuber pipe of suction hood top and gets into in the dust remover, through the purification of dust remover, the dust gets into the dust collection bucket, the air after the purification is gone into the atmosphere under the fan effect, this mine road surface dust removal car is applicable to rugged road surface in mining field specially, avoid simple relying on suction unable to come out the dust of ditch seam the inside, also can improve the suction hood ground too high circumstances that leads to the suction to descend simultaneously.

Furthermore, the air curtain generating device comprises four air supply columns which are arranged at intervals along the circumferential direction, and the air supply columns are sequentially connected in a line along the circumferential direction to form a rectangular structure.
