Background

In coal mining processes, it is most common to transport coal downhole with a belt conveyor. In order to prevent dust from flying and meet the requirements of production process, certain water is required to be added into raw coal during conveying, so that some coal dust is adhered to a belt, and when the coal dust adhered to the belt passes through the tail of the belt conveyor, a sweeper at the tail scrapes the coal dust into a mud collecting pit below the belt conveyor to form coal mud. At present, two methods are commonly adopted for cleaning coal slime, namely a manual shovel removing mode and a pumping mode such as a slurry pump. When the manual shovel removing method is adopted for cleaning, the belt conveyor steel frame structure and the tensioning steel cables are distributed, so that the working space below the belt conveyor is small, workers are difficult to move when cleaning coal slime, and the working efficiency is very low. When the method of the slurry pump row is adopted for cleaning, the slurry is high in solid content and cannot be directly pumped, the pump row can be utilized only after water is added to form slurry, the residual slurry after the pump row is difficult to mechanically clean, and can be manually removed. In order to improve the production efficiency and reduce the labor intensity of workers, an electromechanical dredging device which can completely replace manpower, is environment-friendly, efficient and energy-saving is urgently needed to solve the problem of dredging of a belt conveyor which troubles coal mines for many years.

Detailed Description

The method adopts a fully-packaged treatment process that the coal slime is scraped off from the coal slime, falls into a recovery hopper 2, and is horizontally transported and vertically transported to be discharged to a belt conveyor again through a discharge port.

As shown in fig. 1, the high-efficiency energy-saving spiral belt silt remover comprises a recovery hopper 2, a horizontal driving device 3, a U-shaped groove 4, an axial helical blade 5, a vertical driving device 7, a vertical pipe 8, an axial-free helical blade 9, a discharging pipe 10 and two supports 11; the sweeper below on belt feeder 1 is arranged in to recovery hopper 2, and the coal slime ash that the belt sweeper was scraped falls to the ground, directly falls into recovery hopper 2, and recovery hopper 2 supports through the support 11 at both ends, and recovery hopper 2 bottom seals the setting through U type groove 4, there is axle helical blade 5 horizontal rotation to install in U type groove 4, and the bin outlet that is equipped with on the U type groove 4 lateral wall is passed to the end that has axle helical blade 5, fixes horizontal drive arrangement 3 on one of them side support 11 is used for driving axle helical blade 5, carries out horizontal transport through axle helical blade 5, vertical drive arrangement 7 installs on opposite side support 11 and is used for driving the shaftless helical blade 9 of vertical setting, riser 8 suit is on shaftless helical blade 9 and riser 8 lower extreme is fixed on support 11, and after the horizontal transport, the coal slime carries out vertical lift through shaftless helical blade 9 in riser 8, the feed inlet of riser 8 and the bin outlet intercommunication of U type groove 4, 8 upper ends of riser are equipped with discharging pipe 10, the discharge gate of discharging pipe 10 sets up towards belt feeder 1. The recovered coal slime is reloaded on the belt conveyor 1 through the discharge pipe 10 and is transported out. The whole process realizes that the coal slime does not fall to the ground, the axial helical blade 5 and the shaftless helical blade 9 are transported in a closed environment, the environment is not polluted, the procedure of manually cleaning a coal slime pit is completely cancelled, and the automation is realized. Thereby effectively improving the underground environment, reducing the labor intensity of workers, reducing the labor consumption and improving the economic benefit of enterprises.

The discharge hole of the U-shaped groove 4 is connected with the feed inlet of the vertical pipe 8 through a connecting flange 6.

The bottom of the recovery hopper 2 is smoothly and tightly connected with the U-shaped groove 4.

The length direction of the recovery hopper 2 and the conveying direction of the belt conveyor 1 are vertically arranged on the horizontal plane.

The horizontal driving device 3 and the vertical driving device 7 are both driving motors.

The working principle is as follows: the coal slime ash of adhesion is scraped to the recovery hopper 2 by the sweeper (not shown in the figure) on belt feeder 1, under the action of gravity, the coal slime slides into U type groove 4, there is axle helical blade 5 rotatory under the effect of horizontal drive device 3 in U type groove 4, in 6 propelling movement riser 8 with the coal slime through coupling flange, shaftless helical blade 9 in riser 8 is rotatory under the effect of vertical drive device 7, push away the removal top with the coal slime by the bottom of riser 8, discharge through arranging material pipe 10 and discharge, fall back to belt feeder 1 again, the overall process that the coal slime was retrieved has been accomplished. Wherein, the size of recovery hopper 2 can be confirmed according to the specific specification and size of belt feeder 1 and the scope of scraping of coal slime. The connecting flange 6 is a connecting and sealing part for realizing the connection of the coal slime on the spiral conveying device, and the middle part of the connecting flange contains a rubber sealing ring, so that the sealing performance is ensured, and the leakage of the coal slime is avoided. The recycling hopper 2 and the U-shaped groove 4 are connected smoothly and tightly, so that the coal slime in the recycling hopper 2 can smoothly slide into the U-shaped groove 4 without coal slime leakage. The support 11 not only has the function of supporting and fixing machine equipment, but also has the function of controlling and adjusting the distance between the receiving hopper 2 and the surface of the belt conveyor 1.

In order to ensure that the scraped coal slime falls into the recovery hopper 2, the recovery hopper 2 is wider. Considering that the coal slurry scraped by the belt conveyor 1 has certain viscosity and the coal slurry may contain other impurities which may have adverse effects on the normal operation of spiral conveying, in the aspect of model selection, the horizontal spiral conveying part is designed and manufactured in a mode of a U-shaped groove 4 and an axial spiral blade 5, and the vertical spiral conveying part is designed and manufactured in a mode of a stand pipe 8 and a shaftless spiral blade 9. In the aspect of the type selection of the helical blades, the U-shaped groove 4 of the horizontal helical conveying part can be properly wide, so that the axial helical blades 5 can be adopted for horizontal transportation, and the non-axial helical blades 9 can be adopted for the vertical transportation part. Because the model, specification and erection height of each unit belt conveyor 1 are different, in practical application, the individualized size design can be adopted according to the practical situation of the belt conveyor 1.
