Description

Loading dust suppression device of open-pit mine car

Technical Field

The utility model relates to a cleaning production's technical field, concretely relates to loading dust suppression device of open-pit mine car.

Background

Under the prior art, to the raise dust problem that the open mine loading in-process exists, the general adoption is joined in marriage in addition fog gun car and is restrained the raise dust, but because the dress shovel point is unset, when shovel loading point position changes, needs personnel to operate fog gun car and removes and follow, and is troublesome hard. For the open-pit mine with more shovel loading points, each shovel loading point needs to be provided with one fog gun vehicle, the investment cost is high, each fog gun vehicle needs one operator, and the personnel cost is high.

Meanwhile, as the fog gun vehicle adopts pneumatic spraying, the fog gun vehicle usually sprays at a distance and needs a large amount of water, and usually one fog gun vehicle with a water tank can only meet the operation for 2-3 hours, so that water needs to be frequently added, the fog gun vehicle is only suitable for areas with rich water resources, and the scheme is difficult to realize for areas with deficient water resources.

The ultrasonic spray humidifying system can generate a large amount of water mist, and fine dust is condensed and sinks due to the fact that the fine water mist is very easy to combine with the dust, so that the raised dust is obviously inhibited; the ultrasonic spraying humidification system is mainly used for humidifying in a workshop, is used for eliminating static electricity and reducing the content of solid particles in air, and can also be applied to the loading process of an open-pit mine.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems of high cost, poor practicability and poor dust suppression effect in the prior art that an additional fog gun vehicle is generally adopted to suppress the raised dust aiming at the raised dust phenomenon in the surface mine loading process.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a loading dust suppression device of open-air mine car, including set up the water tank on the mine car, with the fog generator that the water tank is linked together and set up the pipeline in mine car hopper both sides, evenly be provided with on the pipeline and be used for to spray the opening of water smoke in the hopper.

Further, the spray generator comprises a shell, a cavity is formed in the shell, the cavity is divided into a first cavity and a second cavity through a partition plate, the first cavity is communicated with the pipeline, and an ultrasonic atomization plate is installed in the second cavity.

Furthermore, a water mist conveying fan is arranged in the pipeline, a flowing air inlet is formed in the upper portion of the ultrasonic atomization plate, and a dust collection cover is arranged on the flowing air inlet.

Preferably, a ball float valve is arranged at the communication position of the spray generator and the water tank, and the ball float valve can automatically open a valve to supplement a water source when the water level in the cavity is low.

Preferably, a signal generator is arranged on equipment for loading shovels in the mine, a signal receiver is arranged on the mine car, and when the mine car approaches the equipment for loading shovels, the spray generator is automatically turned on to form a layer of water mist in a carriage in advance.

According to the above technical scheme, the utility model discloses a set up ultrasonic spray generating device and signal receiver directly on the mine car, install signal generator on the equipment that is used for the loading shovel, realized that the mine car is close to the automatic ultrasonic spraying system of opening of loading shovel equipment, forms the water smoke in the carriage, through very easily with the water smoke of dust contact, reached better dust suppression effect at the loading in-process when consuming water and reducing.

FIG. 2 is a schematic structural diagram of an ultrasonic spray generator;

in the figure: 1. a water tank; 2. a spray generator; 21. a first chamber; 22. a second chamber; 23. an ultrasonic atomization plate; 3. a pipeline; 4. an opening; 5. A mist delivery fan; 6. a dust collection cover; 7. ball float valve.

Detailed Description

A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

As shown in figure 1, the loading dust suppression device of open-air mine car, including set up water tank 1 on the mine car, with spray generator 2 and the pipeline 3 of setting in the mine car hopper both sides that the water tank is linked together, evenly be provided with on the pipeline and be used for to spray opening 4 of water smoke in the hopper, this preferred embodiment ultrasonic wave spray generator formula design as an organic whole, the water smoke granule that produces is little, and the surface area is big, very easily contacts with the dust, and it is effectual to suppress dirt, and the water consumption is few and simple to operate, only needs the power supply can the operation.

As shown in fig. 2, the spray generator 2 includes a housing, and the housing of the preferred embodiment is made of stainless steel, so as to avoid corrosion caused by long-term immersion, the housing is formed with a cavity, the cavity is divided into a first chamber 21 and a second chamber 22 by a partition board, the first chamber is communicated with the pipeline 3, an ultrasonic atomization plate 23 is installed in the second chamber, the atomization plate is immersed below the water surface, and after the power supply supplies power to the atomization plate, a large amount of water mist is generated.

As shown in fig. 2, a water mist conveying fan is arranged in the pipeline, a flowing air inlet is formed above the ultrasonic atomization plate, a dust collection cover 6 is arranged on the flowing air inlet, so that dust in the air is prevented from entering the generator to influence the atomization effect of the ultrasonic atomization plate, and the flowing air is driven by the water mist driving fan to drive the water mist to enter the pipeline in an accelerating manner.
