Description

Technical Field

[0001] This utility model relates to the field of coal mining, and in particular to a multi-functional machine for intelligent extraction and closed crushing coal and water conveyance. Background Technology

[0002] In modern coal mining, gas extraction technology, coal crushing technology, and underground drill pipe transportation are key aspects to ensure safe and efficient operations.

[0003] The main challenge of gas drainage technology lies in the high concentration and uneven distribution of gas, leading to low drainage efficiency and increased risks. Traditional drainage equipment often struggles to adapt to complex geological structures and fluctuating gas concentrations, easily causing gas leakage and accumulation, which can lead to explosions and other safety accidents in severe cases. Secondly, traditional crushing equipment often suffers from high energy consumption, low crushing efficiency, and poor adaptability. In practical applications, the physical properties of coal and changes in the mining environment make it difficult to maintain stable crushing operations, resulting in uneven coal particle size, affecting subsequent transportation and utilization. Traditional manual transfer is not only inefficient but also prone to personnel injury; the complex underground environment makes the transfer process susceptible to interference, increasing safety risks. In conclusion, although existing technologies have addressed these problems to some extent, more efficient and safer solutions are still needed to improve the overall efficiency and safety of coal mining.

[0026] like Figure 1 As shown, a multi-functional intelligent extraction and closed crushing coal-water conveying machine includes a supporting base plate and a traveling mechanism 4 located at the lower end of the supporting base plate. An extraction buffer box 2 is installed on the supporting base plate. One end of the extraction buffer box 2 is provided with a first slag inlet 1, and the other end is connected to a crushing conveying box 3. A high negative pressure extraction port 201, a low negative pressure extraction port 202, and a butterfly valve 205 for controlling the opening or closing of the high negative pressure extraction port 201 are arranged side by side on one side of the top cover of the extraction buffer box 2. A pressure controller 203 for detecting the pressure inside the extraction buffer box 2 and controlling the opening and closing of the butterfly valve 205 is installed at the tail end of the extraction buffer box 2. A rotary crushing device 302 is installed inside the crushing conveying box 3 for crushing large pieces of coal slag.

[0027] The extraction buffer box 2 is inclined and its lower end is connected to the crushing conveyor box 3. When the coal slag water enters the extraction buffer box 2 through the first slag inlet 1, the coal slag water automatically slides down the inclined inner wall into the crushing conveyor box 3.

[0028] In this embodiment, the extraction buffer box 2 and the crushing conveyor box 3 are connected to the support base plate by bolts.

[0029] The walking mechanism 4 is a tracked type, and the front end of the support base plate is also equipped with a forklift handling mechanism 5, which facilitates the transfer of drill pipes downhole and improves the efficiency of drill pipe transfer.

[0030] Specifically, the first slag inlet 1 flange connection is used to collect and transport the gas extracted from the drill hole and the coal slag water discharged after hydraulic flushing.

[0031] The extraction buffer box 2 has a rectangular parallelepiped structure and a relatively long buffer section. A buffer plate 206 is installed near the first slag inlet 1 to buffer the spray nozzles and reduce the impact of coal slag water on subsequent treatment equipment. In this embodiment, the extraction buffer box 2 is made of pressure-resistant and corrosion-resistant steel to ensure the stability and safety of the system in harsh environments.

[0032] In this embodiment, the butterfly valve 205 is a high-performance hydraulic flange butterfly valve.

[0033] The extraction buffer box 2 is provided with a first slag outlet 204 at one end, and the crushing conveying box 3 is provided with a second slag inlet 301 on one side for connecting the first slag outlet 204. The first slag outlet 204 and the second slag inlet 301 are matched in size to improve the sealing of the extraction buffer box 2 and the crushing conveying box 3.

[0034] The first slag outlet 204 and the second slag inlet 301 are connected by bolts.

[0035] The crushing and conveying box 3 is provided with a second slag outlet 304 on one side, which is connected to a conveying pipe. A rotary crushing device 302 is provided in the center of the crushing and conveying box 3. A slurry pump 301 for conveying coal slag is provided on the upper part of the rotary crushing device 302. A water pipe is connected to one side of the crushing and conveying box 3.

[0036] The pressure controller 203 is a mine-use explosion-proof pressure controller.

[0037] During operation, the slag water and gas generated during drilling enter the extraction buffer tank 2 through the first slag inlet 1. When the pressure inside the extraction buffer tank 2 is negative, the butterfly valve 205 closes, and gas extraction is carried out through the low negative pressure extraction port 202. When the pressure inside the tank is greater than or equal to zero, the butterfly valve 205 opens, driving the high negative pressure extraction port 201 to open. The high negative pressure extraction port 201 and the low negative pressure extraction port 202 simultaneously extract gas. When the pressure inside the tank is less than zero, the high negative pressure extraction port 201 closes. The slag water entering the extraction buffer tank 2 is buffered over a long distance and enters the slag crushing and conveying tank 3 through the first slag outlet 204. Small pieces of slag are directly conveyed over a long distance by the slurry pump 303 through the second slag outlet 304. Large pieces of slag are crushed by the rotary crushing device 302 and then conveyed over a long distance by the slurry pump 303 through the second slag outlet 304, ensuring that slag of different specifications can be processed efficiently and improving the convenience of operation.

[0038] It should be noted that the above embodiments are only used to illustrate the present utility model, but the present utility model is not limited to the above embodiments. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
