Description

A drilling dust removal device

technical field

The utility model relates to the field of mine dust control, in particular to a drilling dust removal device.

Background technique

Dust is very harmful to the human body. Generally, dust larger than 10 μm is easily captured by nasal cavity and tracheal mucus and gradually excreted from the body; dust smaller than 10 μm can penetrate deep into the trachea; and dust smaller than 5 μm can deposit 90% in the trachea , on the alveoli, causing the hyperemia of the alveoli and leading to pneumoconiosis. Miners are very close to the drill hole when drilling, and it is easy to inhale a large amount of dust. Therefore, the drilling dust removal device is also an important part of mine dust control.

At present, the treatment methods for drilling dust include wet drilling, spraying water and water curtain purification. Wet drilling is a common method of drilling, but when the drilling machine used in some areas has no water or a small amount of water, the dust is very large. When drilling, the operator is near the drilling hole, and it is easy to inhale a large amount of dust. The use of spray watering is easy to form water accumulation, which will affect the on-site work. When drilling, the operator should observe the drilling condition, and the way of water curtain purification is used to affect the operator's observation of the drilling condition.

There is also a device that uses a dry dust collector to remove drilling dust. The dry dust collector guides the dust in the drill pipe into the fabric filter bag through the dust guide hose. The fabric filter bag intercepts the dust and discharges the clean air into the roadway. The dry dust collector can only capture part of the dust, and the dust generated between the drill pipe and the borehole wall cannot be removed. If the fabric filter bag is used for a long time, the dust will block the air hole of the filter bag, and a new filter bag needs to be replaced. The maintenance and replacement cost of this device is relatively high.

Contents of the invention

The problem to be solved by the utility model is to provide a drilling dust removal device with simple structure and low cost, which can effectively remove the dust in the drilling.

In order to solve the above-mentioned problems, the drilling dust removal device provided by the utility model includes a water inlet pipe, an air inlet pipe, a sewage discharge pipe with a control valve, and an exhaust fan. The S-shaped dust removal pipe includes at least one upper curved part and one lower curved part. One end of the dust removal pipe is connected to the exhaust fan; there is a nozzle on the water inlet pipe, and the nozzle extends into the S-type dust removal pipe and is located at the top of the straight pipe on the curved part of the S-type dust removal pipe; the air inlet pipe extends into the other end of the S-type dust removal pipe. The air intake pipe is provided with an air suction port; the sewage discharge pipe communicates with the bottom of the S-shaped dust removal pipe.

Above-mentioned inlet pipe can be provided with a plurality of suction ports, can use a dedusting device to dedust a plurality of boreholes like this.

The utility model has the advantages of simple structure, small volume and low cost, and will not generate water accumulation in the roadway, and will not affect on-site construction. The utility model can lay one set in one borehole, also can lay out one set in a plurality of boreholes. The utility model can effectively reduce dust generated during drilling, and provides a treatment approach for reducing the occurrence of miner's pneumoconiosis.

Description of drawings

Fig. 1 is a schematic structural view of an embodiment of the utility model.

detailed description

As shown in Figure 1: the dust removal device consists of a water inlet pipe 1 with a valve 11 and a nozzle, an S-shaped dust removal pipe 2, an air inlet pipe 3 with branch air inlet pipes 31, 32 and 33, and a sewage discharge pipe 5 with a valve 51 and Exhaust fan 6 forms. The S-shaped dust removal pipe 2 has an upper curved portion and a lower curved portion, one end of which is connected to the branch air intake pipes 31, 32 and 33, and the other end is connected to the exhaust fan 6. The water inlet pipe 1 is provided with 3 nozzles, and they stretch into the straight pipe top of the S-type dust removal pipe respectively. The outlet end of the inlet pipe 3 extends into one end of the S-type dust removal pipe, and the outlet end of the inlet pipe is higher than the working liquid level in the S-type dust removal pipe. The sewage discharge pipe 5 communicates with the bottom 4 of the S-shaped dust removal pipe and the bottom 41 of the lower curved part respectively.

When dust removal, place the suction port of the branch air intake pipe near the drill hole, open the water inlet pipe valve 11, the water flow enters the nozzle from the water inlet pipe 1 and sprays out, and the sprayed water fills the sewage discharge pipe 5 and overflows to the S-shaped dust removal pipe 2 When the bottom 4 and the lower curved part 41, open the control valve 51 on the sewage discharge pipe 5, control the sewage discharge speed, keep water at the bottom of the sewage discharge pipe 5 and the S-shaped dust removal pipe 2, and then open the exhaust fan 6 to make the sewage discharge pipe 5 and the bottom of the S-shaped dust removal pipe 2 have water. The wind flow of dust enters the air intake pipe 3 from the branch air intake pipes 31, 32 and 33, and then enters the S-type dust removal pipe 2.
