Dedusting and purifying device for underground tunneling working area

Abstract

The invention discloses a dedusting and purifying device for an underground tunneling working area, and belongs to the technical field of gold mine dedusting. The dedusting and purifying device comprises a bottom plate. A liquid storage tank body, an infusion pump and a support frame body are sequentially arranged on the bottom plate. A case cover body is arranged at the upper end of the support frame body. A movable case body is arranged in the case cover body. A driving assembly and guide assemblies are arranged at the upper end and the lower end of the movable case body respectively. Air filter screens are arranged in the movable case body. One end of the movable case body is connected with an air guide funnel, and the air guide funnel is communicated with an exhaust tube at the input end of a negative-pressure fan which is installed on the inner wall of the top of the case cover body. An exhaust pipe at the output end part of the negative-pressure fan is connected with a machine shell in a secondary dedusting assembly. The dedusting and purifying device for the underground tunneling working area can remove dust from heavy metal dust particles of the whole gold mine, is convenient to maintain, large in dedusting capacity, high in dedusting efficiency, suitable for complex working environments of the gold mine, low in failure rate and easy to maintain, and meets the dedustingrequirement of the gold mine in the actual mining production process.

Description

technical field [0001] The invention relates to the technical field of gold mine dust removal, in particular to a dust removal and purification device for underground excavation work areas. Background technique [0002] A mine is a general term for the wells, chambers, equipment, ground buildings and structures that form the underground coal mine production system. Sometimes the inclined shafts, shafts, and adits in the underground development of mines are also called mines. The determination of the size of each mine field, production capacity and service life of each mine is one of the key issues that must be resolved in the design of the mine itself. [0003] At present, there are the following technical problems in the mining and production process of gold mines: 1. A large amount of dust impurities often appear in the mining and production process of gold mines. The dust of gold mines is mainly composed of ore particles and other powders.

Problems solved by technology

[0003] At present, there are the following technical problems in the mining and production process of gold mines: 1. A large amount of dust impurities often appear in the mining and production process of gold mines. The dust of gold mines is mainly composed of ore particles and other powders. During the mining process, the dust generation is mainly concentrated in the drilling and blasting process, crushing, screening and belt conveying process. If the underground workers inhale this kind of dust for a long time, it will cause great harm to the human body, so it is necessary to use the corresponding dust removal device to deal with it. Dust, however, the existing dust removal device is difficult to maintain, has a single function, and cannot cope with the complex working environment in the mining and production process of gold mines. In addition, gold mine dust often contains a large amount of heavy metal dust particles, which is often harmful to the respiratory tract of workers. It will cause irreversible damage and seriously affect the health and work efficiency of the staff; 2. In the process of dust removal device processing dust, the function is relatively single, which cannot solve the dry dust environment of the gold mine underground, and the gold mine dust will often be strong Attached to the filter net, the filter function will gradually decrease or even disappear as the production process continues, and the dust content in the gold mine cannot be reduced; 3. During the dust removal process of the heavy metal dust particles in the gold mine, the dust has not been effectively removed Centralized collection leads to the secondary flying of heavy metal dust particles in the gold mine, thereby polluting the environment again; 4. The overall cost of the existing device is expensive and the failure rate is high. During use, due to the complex terrain environment of the gold mine, some maintenance parts It is difficult to transport it to the inside of the mine in time, resulting in the stagnation and shutdown of the dust removal work. Moreover, as the mine excavation continues, the heavy metal dust particles of the gold mine are also continuously produced. The existing dust removal devices on the market are often in this Faults occur in such an environment, and maintenance is difficult, which is difficult to meet the actual mining production process of gold mines.
