Description

Coal box lifting mechanical cleaning and coal spreading system

technical field

The invention relates to a mechanical cleaning and spreading coal system, in particular to a coal box lifting type mechanical cleaning and spreading coal system.

Background technique

When the vertical shaft skip is used for lifting, when the loading equipment in the loading chamber loads coal into the skip, some coal will fail to enter the skip and fall to the bottom of the well. The amount of coal accounts for about 3‰-5‰ of the daily lifting coal amount of the mine.

The coal spreading and cleaning methods at the present stage mainly include: bucket cleaning and coal spreading (sedimentation tank type and dewatering scraper sedimentation tank type), vertical well small skip cleaning and coal spreading, inclined alley small skip cleaning and coal spreading, vertical shaft grab bucket cleaning and spreading Coal, swing gate side lane mine car cleaning and scattering coal, etc.

When the coal sprinkler is mixed with the wellbore water to form a coal-water mixture, it will cause great difficulties in the cleaning work, and the coal sprinkler needs to be cleaned regularly. At the same time, the manpower and financial costs brought by the cleaning process are also relatively large. Therefore, a reasonable mechanical design It is very necessary to clean the coal spreading system of the main shaft.

detailed description

The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

Referring to Fig. 1 and Fig. 2, the mechanical cleaning coal spreading system of the present invention includes: screw blade 7, first motor 8, overrunning clutch 9, coal bridge 10, coal lifting box 2, second motor 4 and dredging pump 3. Wherein, the overrunning clutch 9 is a ratchet mechanism with one-way output power, which is installed on the output shaft of the first motor 8, and the rotation of the helical blade 7 and the lowering and retracting of the coal bridge 10 are controlled by the first motor 8 and the overrunning clutch 9. control, specifically:

When the first motor 8 reverses, the overrunning clutch 9 outputs power outwards, drives the screw blade 7 to rotate, drives the coal spreading movement, and drives the main shaft of the coal bridge 10 to rotate at the same time, so that the coal bridge 10 is lowered to realize coal spreading without omission. is loaded;

When the first motor 8 was rotating forward, the overrunning clutch 9 did not output power outwards, and the helical blade 7 did not move, but the main shaft driving the coal bridge 10 reversely rotated, so that the coal bridge 10 was retracted to facilitate the passage of the coal box 2.

Referring to Figure 1, the helical blade 7 is arranged in the coal slant eye 11 between the bottom 5 of the main shaft and the small coal lifting eye 1, the high end of the slant eye 11 is located below the bottom 5 of the main shaft, and the low end is located At the coal inlet of the small eye 1, the first motor 8 and the coal bridge 10 are located at the lower end of the coal slant eye 11, and a number of water leakage holes are arranged at the bottom of the coal slant eye 11. When the coal-water mixture is transported on the spiral blade 7, The water is separated from the coal sprinkling, and the separated water flows into the bottom of the coal lifting eyelet 1, and is pumped to the road drainage system through the dredging pump 3, and the separated coal sprinkling falls into the coal lifting box 2 in the coal lifting eyelet 1 , the coal lifting box 2 rises under the drive of the second motor 4, and the coal is transported to the top of the coal lifting eyelet 1, and finally transported to the bottom alley (not shown), the bottom coal bunker through the conveyor belt, etc. (not shown), thereby forming a closed circulation system.

Due to the strong stickiness of spreading coal, we have also installed a funnel body 6 at the bottom of the main well bottom 5, i.e. a funnel-shaped closing mouth, and its inclination angle is 45°-60°, preferably 50°, which can achieve Sprinkle coal and gather smoothly to the outlet of funnel body 6 under the action of gravity.

With reference to Fig. 2, in the present embodiment, the coal bridge 10 that we adopt, its main body is made up of two flat plates, and these two flat plates can flexibly rotate around the connecting shaft, simple in structure, easy to operate and implement.

System of the present invention, its working principle is as follows:

The first motor 8 reverses, and the overrunning clutch 9 outputs power outwards to drive the screw blade 7 to rotate, driving the coal spreading movement (during the movement, water and coal are automatically separated), and simultaneously drives the main shaft of the coal bridge 10 to rotate, so that the coal bridge 10 Lower it down and start to load and sprinkle coal in the coal lifting box 2. When the coal lifting box 2 is full, the first motor 8 rotates forward, the overrunning clutch 9 does not output power outward, and the spiral blade 7 does not move, but the drive coal bridge 10 The main shaft reversely rotates so that the coal bridge 10 is retracted. At the same time, the second motor 4 is started to promote the coal lifting box 2, and transport the scattered coal to the top of the coal lifting eyelet 1.

Therefore, the whole system only needs to control the forward and reverse rotation of the two motors within an appropriate time interval to realize the autonomous mechanized cleaning of the main shaft coal sprinkling.

Because we are provided with coal bridge 10 in mechanical cleaning coal-spreading system of the present invention, so well realized that coal-sprinkling is without omission, all transfers in the coal-lifting box 2 from slipping coal oblique eye 11 safely.

To sum up, the system of the present invention can not only effectively separate the water from the sprinkling coal, but also ensure that all the sprinkling coal is transported out without omission.

It should be noted that the above embodiments do not limit the present invention in any form, and all technical solutions obtained by means of equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
