Description

A large environmental protection chute for mining

technical field

The utility model relates to a mine transportation system, in particular to a mine-used large environmental protection chute.

Background technique

] The chute process is widely used in mines, and chute drawing is one of the most effective and economical methods to overcome the height difference. Generally, it is mostly used in ore transportation of metal mines and backfilling of abandoned open-pit pits, especially hillside open-pit mines are more suitable for the application of chute transportation technology. Because the chute required for open-pit mine transportation has the characteristics of large transportation volume and large height difference, not only the stability of the chute transportation must be considered, but also the safety and environmental protection issues. Ordinary chutes cannot meet the requirements of large height difference and large transportation volume. delivery requirements. Therefore, need to provide a kind of novel mining environment-friendly type large height difference chute.

Contents of the invention

The purpose of the utility model is to solve the above-mentioned deficiencies in the prior art, and to provide a large-scale environmental protection chute for mining. The chute has the characteristics of large flow rate and large height difference, and is safe and environmentally friendly, that is, it can avoid the harm of flying stones and pollution of flying dust during transportation, and can also avoid the blockage of the conveying system.

The utility model is realized in this way: it includes a feed inlet, a chute channel, a spray device, a material concentration area, a retaining wall at the discharge port, and a protective net; the spray device is composed of a bracket, an air compressor, a pressurized water tank, a solar The energy storage power supply component, the solar panel, and the spray head are connected. The air compressor and the pressurized water tank are connected by the water tank pressure pipeline, and the pressurized water tank and the spray head are connected by the water delivery pipeline.

The specific connection is that the feed port is installed at the feed end of the chute channel, the spray head of the spray device is installed at the lower discharge end of the chute channel, the material collection area is closely connected with the chute outlet of the chute channel, and the material concentration area is equipped with The retaining wall of the outlet and the protective net are installed on the upper parts of the U-shaped sides of the chute channel through the connecting frame.

The utility model has the advantages that the environmentally friendly mining chute has a U-shaped cross-section structure, and the U-shaped chute can prevent the dust from spreading and the chute from being blocked, and the chute body is made of reinforced concrete with a small friction coefficient and is strong. The upper part is equipped with a steel material inlet, the middle of the chute is equipped with a protective net, and the lower part is equipped with a wet dust removal system and a sprinkler device, which can effectively prevent the dust from spreading. A safety protection wall is installed at the chute exit to effectively prevent flying stones from splashing.

The utility model can adapt to the operation under the condition of large height difference, has a large material flow, and has the functions of dust removal and preventing flying stones from splashing, and is suitable for large-scale mine transportation.
