A mining impact water bath dedusting device

Technical Fields

The utility model relates to an impact water bath dedusting device for mines, in particular to an impact water bath dedusting device for air purification in underground mines. The utility model belongs to the technical field of mine ventilation and dust removal.

Background technique

A lot of dust will be generated in the production of underground mines, such as rock drilling, blasting, crushing, loading and unloading, lifting, transportation, spray anchor support and other work will generate a lot of dust. Long-term inhalation of productive dust can cause various diseases of the respiratory system, such as pneumoconiosis, dust bronchitis, pneumonia, and rhinitis. Pneumoconiosis is a statutory occupational disease. It is very important to use dust removal devices to capture dust, purify the air, create a good working environment, and prevent occupational diseases.

The production of underground mines requires large air volume, cramped space and complex environment. Ordinary dust collectors are not suitable for dust removal in mines due to their large volume, large space occupation, and limited air volume. At present, the dust collectors used in mines are only small-scale dust collectors with a small processing air volume, which can only be used for dust removal in tunneling roadways, and can't do anything about the air intake with excessive dust concentration. Therefore, it is necessary to develop a mining dust removal device suitable for special underground spaces, with large air volume, high dust removal efficiency, convenient maintenance and strong practicability.

Contents of the invention

The technical problem to be solved by the utility model is to provide an impact water bath dedusting device used in underground mines, which has a large air volume, high dedusting efficiency, simple structure, low cost, convenient use, easy maintenance and strong practicability.

The technical scheme adopted by the utility model is: a windshield for a closed roadway is arranged at the upstream of the wind flow in the mine, a series of downwardly extending conduits are installed on the windshield, and the lower port of the conduit is inserted into a pool on the bottom plate of the roadway behind the windshield. A series of guide plates for the airflow to be bent upwards and downwards, an airtight wall is arranged downstream of the air flow behind the deflected guide plates, and an axial flow fan is arranged on the airtight wall.

The windshield upstream of the wind flow is Z-shaped, the vertical plates of the vertical section are respectively connected to the roadway roof and the roadway bottom plate, the horizontal plate of the horizontal section is arranged with a vertically extending duct, and the outlet of the duct is equipped with a nozzle; the bending guide plate is A series of retaining walls with both ends fixed to the roadway walls on both sides, forming a channel for the airflow to turn up and down between the retaining walls, and the lower part of the foremost retaining wall extends into the pool.

A slant plate whose reflection direction faces the inlet of the conduit is arranged above the transverse plate of the horizontal section.

The lower part of the front vertical plate of the windshield is fixed on the end retaining wall, the last retaining wall of the guide plate is fixed on the end retaining wall, the front and rear retaining walls are the front, rear and front edges of the pool, and the front end retaining wall is The upper part of the wall is provided with a water supply pipe leading to the pool, and the lower part of the rear end retaining wall is provided with a sewage pipe leading out of the pool.

An inspection door is also installed on the airtight wall, and a sealing gasket is arranged on the assembly door frame of the inspection door.

The efficiency and resistance of the utility model depend on the impact velocity of the airflow and the insertion depth of the nozzle. When the impact velocity is constant, the dust removal efficiency and resistance increase with the increase of the nozzle insertion depth; when the insertion depth is constant, the dust removal efficiency and resistance increase with the impact velocity.

The beneficial effects of the utility model are: clever use of the special space of the roadway, adapting measures to local conditions, making the roadway an impact water bath dust removal device, which can better solve the problem of purifying the dusty airflow in the mine; at the same time, using the length of the roadway to break through the limitation of the underground space , thus solving the problem of small air volume in the past. The device has high dust removal efficiency, simple structure, convenient use, easy maintenance and strong practicability.
