Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mine equipment, in particular to a drilling water-coal separation metering all-in-one machine. BACKGROUND

[0002] During the process of underground coal mining, measures such as hydraulic punching and hydraulic slotting are needed to increase the permeability, but these measures will produce a large amount of coal-water mixture, which needs to be metered and separated into coal and water before being stored in the warehouse. The Chinese patent application with publication number CN113062703A discloses a three-proofing complete equipment orifice sealing device for drilling and punching, which seals the surrounding of the drilling hole as the inlet end of the coal-water slag and gas collection in the drilling hole. The orifice sealing device is a cylindrical barrel structure. The coal-water collection box includes an upper box body and a lower box body, which are hinged on one side and closed to form an upper and lower buckled box after rotation. A sealing port is provided on the side wall of the box and is connected to the orifice sealing device. The coal-water separation vehicle includes a gas-liquid separation device, a lifting device and a drainage tank. The liquid inlet of the gas-liquid separation device is connected to the lower interface of the coal-water collection box. The centrifugal separator includes a horizontal screw centrifuge, which is used for secondary separation of the separated sewage in the drainage tank. The device basically realizes the integrated design of drilling and coal-water separation, but the coal-water separation equipment needs a series of devices such as screw centrifuge, water tank-lifting device, and the structure is relatively complex, which increases the maintenance difficulty and use cost.

[0065] The blowout hole module 11 comprises a box 1102 fixed at the first end of the sliding frame 1202, the box 1102 is provided with a first interface 1103, a water and coal outlet 1101, a sealing port 1104 and a second outlet 1105, wherein the bottom of the water and coal outlet 1101, the axis of the sealing port 1104 coincides with the axis of the chuck 1214, the water and coal outlet 1101 is fixedly connected with the metering module, and the first interface 1103 and the second outlet 1105 are used for connecting a gas recovery device.

[0066] The drilling process is as follows: first, the drilling machine 1 is moved to a predetermined position, the fourth clamping oil cylinder 18, the third clamping oil cylinder 15 and the first clamping oil cylinder 1204 are output, the drilling machine is fixed on the work station from the upper and lower two directions, so that the stability of the drilling machine is maintained, then the drill rod is installed, the chuck 1214 holds the main drill rod, the height of the drill rod is adjusted through the lifting oil cylinder 1215, the drilling angle of the drill rod is adjusted through the first rotary support 1211 and the second rotary support 1216, then the second clamping oil cylinder 1209 is output and the wall is clamped; the two second clamping oil cylinders 1209 can balance the reaction force received by the equipment during drilling, maintain the stability of the position of the equipment, and reduce the damage of the drill bit module 12 to the equipment due to uneven stress during drilling. Start the drilling motor, the piston rod of the second feeding oil cylinder 1217 is retracted, the drill rod is driven to drill, after the piston rod of the second feeding oil cylinder 1217 is fully retracted, the first feeding oil cylinder 1203 and the second clamping oil cylinder 1209 are output at the same time, the sliding frame is driven to move, so that the drill rod continues to drill, and the first feeding oil cylinder 1203 and the second feeding oil cylinder 1217 are arranged behind to make the drilling stroke larger. When the piston rod of the first feeding oil cylinder 1203 extends to the maximum stroke or a predetermined stroke, the drill rod holding device 1201 clamps the drill rod, the chuck 1214 releases the drill rod, the second feeding oil cylinder 1217 is output to the maximum stroke; then the chuck 1214 clamps the drill rod, and the drill rod holding device 1201 is released; then the piston of the first feeding oil cylinder 1203 and the second clamping oil cylinder 1206 is retracted, the sliding frame 1202 is driven to return to the initial state, and the piston of the second feeding oil cylinder 1217 is also retracted in this process, so that the drill rod remains stationary; after the sliding frame 1202 returns to the initial state, the drill rod holding device 1201 clamps the drill rod, the chuck 1214 releases the drill rod, the second feeding oil cylinder 1217 is output to the maximum stroke, then the chuck 1214 clamps the drill rod, and the drill rod holding device 1201 is released, and drilling is performed again.

[0067] The coal-water mixture produced by the drilling flows out of the water-coal outlet 1101, flows through the second feeding pipe 2434, completes flow metering through the metering device 2433, enters the separation assembly 2412, and the filter screen filters out the water therein. The water flows out through the water outlet 2413. With the operation of the pipe chain, the coal is discharged through the coal outlet 2418 under the driving of the scraper 2427. The brush 32 brushes off the coal slurry deposited on the filter screen to prevent the filter screen from being blocked. The adjusting oil cylinder 22 can be adjusted according to the water content in the coal slurry mixture, so as to change the inclination degree of the coal-water separation module 24.
