Online main drainage pump water suction kettle anti-blocking dredging device for coal mine

Abstract

The invention discloses an online main drainage pump water suction kettle anti-blocking dredging device for a coal mine, and belongs to auxiliary dredging devices for coal mines. The anti-blocking dredging device comprises a driving portion, an arc guide sliding channel, a vertical guide sliding channel, a stirring sand discharging pump, a high-pressure water jetting device, an electronic control system and a control valve set. The driving portion is connected with the vertical guide sliding channel, and the stirring sand discharging pump is arranged on the vertical guide sliding channel, and can vertically move along the vertical guide sliding channel under the action of a jack. The vertical guide sliding channel is arranged on the arc guide sliding channel through a roller, and can rotate forwards and backwards around the arc guide sliding channel under the action of the driving portion, and therefore the stirring sand discharging pump is driven to do vertical and circumferential motion around a water suction kettle to comprehensively removing sludge around the stirring sand discharging pump. The high-pressure water jetting device can flush apart and dilute the sludge to facilitate pumping and drainage. The electronic control system and the control valve set are used for system control. The device is compact in structure, and can be used for a long time after being mounted once, the water suction kettle is cleaned online, manual dredging is not needed, the labor amount of workers and cost are reduced, and the device is economical, safe and efficient.

Description

technical field [0001] The invention relates to an auxiliary desilting machine for coal mines, in particular to an anti-blocking and desilting device for an online main drainage pump suction tap used in coal mines. Background technique [0002] The main underground drainage pump of coal mines is generally installed in the pump room, and a special water storage tank and water suction well are built. The water pump lifts water from the water suction well and discharges it to the ground. Since the underground water is accompanied by the coal mining process, a large amount of coal slime is mixed. After the coal slime water flows into the water tank, it gradually deposits in the water tank and the water suction well. Over time, the sludge in the water tank accumulates. If it is not cleaned in time, it will gradually expand and bury the bottom of the water suction well and the water suction faucet of the water pump. The water pump cannot normal work. The mine must be cleaned freq...

[0002] The main underground drainage pump of coal mines is generally installed in the pump room, and a special water storage tank and water suction well are built. The water pump lifts water from the water suction well and discharges it to the ground. Since the underground water is accompanied by the coal mining process, a large amount of coal slime is mixed. After the coal slime water flows into the water tank, it gradually deposits in the water tank and the water suction well. Over time, the sludge in the water tank accumulates. If it is not cleaned in time, it will gradually expand and bury the bottom of the water suction well and the water suction faucet of the water pump. The water pump cannot normal work

The mine must be cleaned frequently by hand, and the water-absorbing faucet must be dug out from the silt to ensure the normal drainage of the water pump. Although this method is effective, each water-absorbing well is switched back and forth, which affects the normal drainage of the mine and the workers go deep into the water-absorbing well. Time-consuming and labor-intensive, extremely unsafe
