A kind of sludge cleaning device in coal mine water tank

Abstract

The invention provides a device for removing silt in a water sump of a coal mine. Particularly, the device for removing silt in the water sump of the coal mine is suspended in the water sump through suspension arms, silt is lifted and transported through cooperative rotation of an impeller and spiral blades, water in silt is squeezed out through a high-density woven sleeve, and then silt is removed. The device for removing silt in the water sump of the coal mine is characterized in that a main body cylinder is sleeved with a guide sleeve, and the guide sleeve can slide along the main body cylinder; one ends of the two suspension arms are symmetrically arranged on the guide sleeve, supporting plates are correspondingly arranged at the other ends of the suspension arms separately, reinforcing rib plates are arranged between the supporting plates and the suspension arms, and elastic rubber mats are arranged on the supporting plates; one end of the main body cylinder communicates with a suction pipe through a screen pipe, the suction pipe is a horn mouth, and the diameter of the small end of the suction pipe is the same as the diameter of the screen pipe; a limiting ring is arranged onthe inner wall of the suction pipe and located at the small end of the suction pipe, and a plurality of clamping grooves are formed in the big end of the suction pipe at equal angles; and a motor installation base is arranged in the other end of the main body cylinder in a sleeved mode and is coaxial with the main body cylinder.

Description

technical field [0001] The invention relates to a sludge cleaning device in a coal mine water tank, which relates to a device for cleaning the sludge deposited at the bottom of the water tank during the working process of the coal mine water tank, and belongs to the field of coal mine facilities. In particular, it relates to a device that suspends the suspension arm in the water tank, and through the coordinated rotation of the impeller and the spiral blade, the sludge is lifted and transported, and the water in the sludge is drained through the high-density braided sleeve to clean the sludge.

[0002] At present, in the coal mine mining site, water seepage is easy to occur in the rock formation. By diverting the seepage water into the water tank, the pre-set water tank is used to buffer the water, and coal dust and various garbage will also enter the water tank with the water flow. Sludge is accumulated at the bottom of the water storage tank, which affects the discharge and buffer capacity of the water tank. Since the water tank contains coal powder, the sludge needs to be excavated to eliminate the functional hindrance of the sludge to the water tank, and the coal powder can also be recycled. The traditional The cleaning method is to drain the water, then manually clean the silt in the water tank, and transport the silt away by mine trucks, which is time-consuming and laborious, and requires rainfall to be drained. In the event of sudden water damage, there are hidden dangers to the safety of personnel. The risk factor is high. The existing water tank will be equipped with a filter device, but its cleaning capacity is limited. It can only filter and cannot clean the deposited silt. Moreover, the filter device is large in size, does not filter continuously, and has low working efficiency, which affects the sludge. In the existing method of collecting sludge, the sludge and water are directly extracted, so that the water and pumping need to be processed after drying the sludge. the water to be discharged;

[0003] Publication number CN206157856U discloses a coal mine central water tank sludge cleaning device, which is characterized in that: a coal mine central water tank sludge cleaning device, a coal mine central water tank sludge cleaning device, including a sedimentation filter box, a stirring device and a water pump arranged in the central water tank; First enter the filter box, filter the garbage in the sewage, settle the floating coal and silt, and then enter the central water tank. The stirring device installed in the central water tank continuously stirs the water in the central water tank to prevent the formation of Precipitation; when the water level in the water tank exceeds the design elevation, the water pump installed in the central water tank will pump the water in the central water tank out of the tank, and the device will first filter the water entering the water tank through the filter box. The volume of the tank is limited, and after filtering to a certain limit, it needs to be replaced or cleaned. The humidity of the sludge inside is relatively high, and the flow path of the water flowing into the tank is uncertain, so the sludge in the tank cannot be completely cleaned.
