Spirally adjustable type mining automatic adding and mixing device for dust falling agent

Abstract

The invention particularly relates to a spirally adjustable type mining automatic adding and mixing device for a dust falling agent. The problems that an existing adding device is serious in energy loss and high in equipment cost, and the accuracy of the adding amount is hard to control are solved. A turbulent flow pipe and an on-off valve are arranged on a water inlet pipe, a flowmeter and a valve are arranged on a liquid inlet pipe, and a concentration detector is arranged on a liquid outlet pipe. A turbine comprises a columnar shell, an adjusting knob is arranged on the right end face of the columnar shell, a threaded liquid conveying shaft is arranged in the center of the columnar shell, and a left hub and a right hub are arranged on the threaded liquid conveying shaft. A disc-shaped support is arranged on the left side of the left hub, arc-shaped groove holes are evenly formed in the right hub, an adjusting bevel gear is arranged on the left side of the right hub, and a connecting rod is arranged between the adjusting knob and the adjusting bevel gear. Rotary heads are arranged between the left hub and the right hub, fan connecting pieces are arranged on the outer sides of the rotary heads, and drainage fan blades are arranged on the outer sides of the fan connecting pieces. According to the device, the aim of automatically injecting the dust falling agent into a downhole water pipe through water pressure is effectively achieved.

Description

technical field [0001] The invention relates to an automatic adding device for underground coal mines, in particular to a screw-adjustable automatic adding and mixing device for mine dust suppressant. Background technique [0002] With the increasing attention to coal mine safety, the control of mine dust has attracted more and more attention. Due to the convenience of water bodies, the most commonly used dust reduction method is spray dust reduction. However, due to the hydrophobicity of hard coal in my country, this is serious. Affected the spray dust reduction phase rate. In order to improve the combination ability of atomized water mist and coal dust, the most common way is to add dust suppressant in water. [0003] However, the existing dust suppressant automatic adding device needs external power supply, which not only consumes energy but also increases the cost of the equipment; there are also dust suppressant automatic adding devices that inhale the dust suppressant ...
