Problems solved by technology
[0002] During the working process of the coal shearer underground, the environment is harsh, and the flying dust is too large, which seriously affects the work efficiency. The dust suppression effect of water alone is poor, and the imported dust suppression agent is expensive. The brain is how to evenly add the expensive dust suppressant to the water flow. Various methods have been tested by major coal enterprises, but the adding procedure is complicated and the waste is astonishing

An automatically unpowered liquid adding pump belongs to the field of coal mine production and comprises a bracket with travelling wheels arranged at the bottom, wherein a liquid conveying pump, a manual reversing valve and a flow control valve are arranged on the bracket; a storage bin and a mixing barrel are arranged above the liquid conveying pump; the storage bin is provided with a feed port and a discharge port; a liquid level meter is arranged on one side of the storage bin; the mixing barrel is provided with a high pressure water inlet, a raw material inlet and a mixed solution outlet; a dust cap is arranged at the feed port of the storage bin; the discharge port of the storage bin is communicated with a cavity on the left side of the pump body of the liquid conveying pump through a feed valve; the cavity on the left side of the pump body of the liquid conveying pump is connected with the raw material inlet of the mixing barrel. According to the invention, additional power is not required, based on the water flow rate of the high-pressure water source in a work site, a dust-settling agent and the water are mixed and sprayed to the work site; moreover, the dust-settling agent is controllable in matching amount according to the dust concentration, the normal water supply of the working face is not affected, the operation is simple, and the movement is convenient.
Description
technical field [0001] The invention belongs to the field of coal mine production, and in particular relates to a non-powered liquid automatic adding pump for reducing coal mine dust content. Background technique [0002] During the working process of the coal shearer underground, the environment is harsh, and the flying dust is too large, which seriously affects the work efficiency. The dust suppression effect of water alone is poor, and the imported dust suppression agent is expensive. The mind is how to evenly add the expensive dust-reducing agent to the water flow. Various methods have been tried by major coal enterprises, but the adding procedure is complicated and the waste is astonishing. Contents of the invention [0003] The purpose of the present invention is to solve the above problems and provide a non-powered liquid automatic adding pump with simple operation, convenient movement and uniform spraying. [0004] The technical solution to achieve the above-menti...
