Description

Technical Field

[0001] The utility model relates to a processing device for a dust suppressant for a mine road, belonging to the technical field of dust suppressant processing devices. Background Art

[0002] In most mining projects, ore needs to be transported by mine trucks. During the transportation process, the mine trucks driving on the mine roads are prone to generate dust, which pollutes the environment. At the same time, the dust will drift into the surrounding environment, which will harm the health of on-site workers. The dust pollution on the mine roads is highly dispersed and the dust is not easy to settle, which will have a continuous adverse impact on the mining environment.

[0003] At present, the main methods for suppressing dust on mine roads are watering, covering and chemical dust suppression. Although watering is simple and easy, it has the disadvantage of wasting water resources. At the same time, as the water evaporates, it will be raised again by external disturbances, resulting in a short dust suppression cycle and poor dust suppression effect. Covering dust suppression uses a lot of manpower and material resources, which cannot effectively solve the problem, and the corrosion of the tarpaulin itself will cause pollution to the cover and the environment again. Chemical dust suppression has obvious dust suppression effect, can control costs, and has a wide range of applications.

[0004] Chemical dust suppressants can be divided into three categories: dust wetting agents, binders and coagulants. Powdered eco-friendly dust suppressants are made from a variety of modified natural plant fibers. The liquid used has high-quality moisturizing, bonding, film-forming and crusting functions, so it can effectively fix dust and form a protective film on the surface of the material. Powdered dust suppressants are made from modified natural plant fibers. They are non-toxic, harmless, non-polluting, non-corrosive, non-flammable and completely biodegradable. They do not harm the soil and plants and do not affect the quality of the deposits. Therefore, they are widely used. However, dry powder dust suppressants require mixing various materials. When dry powder raw materials are mixed with solvent raw materials, agglomeration often occurs, causing the spraying pipe of the dust suppressant spreader to be blocked. The continuity of its spraying cannot be guaranteed, and the efficiency is difficult to meet the standards, resulting in increased production costs for enterprises. Utility Model Content

[0005] The utility model provides a processing device for a mine road dust suppressant, which is designed to solve the problem of easy agglomeration of dry powder raw materials and solvent raw materials when they are mixed in the existing dust suppressant production device.
