Description

Technical Field

[0001] The invention relates to the technical field of underground coal slime mining, in particular to a mining coal-water separation and processing device with a novel mud pump. Background Art

[0002] Underground coal mine silos and various coal slurry sedimentation tanks (pits) are core facilities for ensuring safe production and preventing mine flooding. Their effective operation is directly related to the safety and production efficiency of the entire mine. With the continuous extension of mining depths and the widespread adoption of mechanized production, the amount of water inflow (including geological water inflow and production water) in mines has shown a gradual increase. This inflowing water carries large amounts of coal (rock) slurry into the silos, sedimentation tanks, and pits. This phenomenon directly reduces the effective water storage capacity of the underground silos, weakening their flood control and drainage capabilities. Furthermore, this coal (rock) slurry enters the main drainage pump along with the water flow, exacerbating pump wear, shortening equipment life, increasing maintenance costs, and posing a serious threat to the mine's normal drainage system.

[0003] In this context, mine clearance operations and coal slime dewatering have become key links affecting the normal production of mines. At present, the conventional processing process is to use a clearance machine to excavate the coal slime underground and then transport it out, but there are many problems in actual operation. On the one hand, the large amount of mud remaining in the working area after excavation is difficult to collect efficiently. Traditional manual cleaning is inefficient and ineffective. The existing simple collection device cannot adapt to the complex underground working conditions, resulting in long-term mud residue, further occupying the water tank space and affecting its water storage function. On the other hand, when the coal slime is transported out of the separation device, the existing conveying equipment is prone to blockage, severe wear and other problems when facing coal slime with sticky and granular characteristics, which seriously affects the continuity and stability of coal slime transportation, thereby restricting the efficiency of the entire clearance and dewatering process. Summary of the Invention

[0004] In order to solve the problems of long-term mud retention and easy blockage during transportation during the above-mentioned cleaning operations and coal slime dehydration treatment, the present invention provides a mining coal-water separation and treatment device with a new type of mud pump.

[0005] The technical solutions of the present invention are as follows: A coal-water separation and treatment device for mining with a novel mud pump includes a cleaning device, which includes a traveling mechanism for moving the entire device. A material collecting mechanism is provided at the front end of the traveling mechanism, and the material collecting mechanism is connected to a feeding mechanism extending toward the rear end of the device. A receiving hopper is provided at the end of the walking mechanism, and a discharge port is provided at the end of the receiving hopper away from the walking mechanism, and the discharge port of the feeding mechanism is located above the receiving hopper and within the area covered by the receiving hopper in the vertical direction; A mud pump mechanism is provided on the side of the receiving hopper, including a pump body installed with the receiving hopper, a driving device is installed on the outside of the pump body, the pump body is connected to multiple material ports, a hose is installed around the inner wall of the pump body, and the two ends of the hose are respectively connected to any two material ports, and the outsides of the two material ports connected to the hose are both connected to material pipes, one of which is connected to the receiving hopper, and the other is connected to the underground water tank; A cam structure is coaxially mounted in the pump body with the output end of the driving device. The cam structure includes at least two cam portions, and the cam portions extend beyond the minimum distance from the rotation center to the hose relative to the rotation center. Driven by the driving device, the cam portions can alternately squeeze the hose. The traveling mechanism is provided with a pumping mechanism, and the pumping mechanism is provided with two output ends, which extend into the receiving hopper and are alternately connected with the discharge port, so as to pump out the coal slime in the receiving hopper in a cyclical manner.

[0006] The specific design of the pump body is that the inner cavity cross-section of the pump body is circular, and there are two material ports connected to the outside of the pump body, which are arranged symmetrically. The hose is arranged around the inner cavity wall of the pump body and its two ends are connected to the two material ports.

[0007] In order to improve the suction and discharge force of the coal slime, the minimum distance that each cam part can reach from the inner wall of the pump body when rotating with the driving device is not more than 2 times the thickness of the hose wall.

[0008] The specific design of the cam structure is that the cam structure includes a mounting plate connected to the output end of the driving device, and a plurality of cam parts are installed along the circumference of the mounting plate.

[0009] The specific design of the cam part is that the mounting plate is set to a triangular shape, and there are three cam parts, which are respectively rotatably installed at the three corners of the mounting plate. During the rotation process, the two cam parts in contact with the hose separate the hose to form a sealed cavity.

[0010] In order to facilitate the stirring of the coal slime temporarily stored in the receiving hopper, improve the fluidity and slow down the sedimentation of the coal slime, a stirring assembly is provided in the receiving hopper, and the driving shaft of the stirring assembly extends into the pump body and is connected to the output end of the driving device.

[0011] The specific design of the pumping mechanism is as follows: the pumping mechanism includes two main drive cylinders and two auxiliary drive cylinders, both of which are located on the traveling mechanism. The output ends of the two main drive cylinders are respectively connected to the piston rods of the two auxiliary drive cylinders. The two auxiliary drive cylinders are circulated and connected to the discharge port and the receiving hopper through a connecting structure. A water tank is provided between the main driving cylinder and the auxiliary driving cylinder, and a reversing device is provided in the water tank, which can control the alternating extension and retraction of the two main driving cylinders.

[0012] The specific design of the connection structure is that the connection structure includes a double-hole plate in the receiving hopper, and the openings of the two auxiliary drive cylinders are respectively connected to the double-hole plate; A connecting pipe connected to the discharge port is provided in the receiving hopper, and a swinging oil cylinder is provided in the receiving hopper. The output end of the swinging oil cylinder is connected to the connecting pipe through a swing arm, which can drive the connecting pipe to circulate and connect with the two holes of the double-hole plate.

[0013] In order to avoid the backflow of coal slime in the receiving hopper, the material pipe connected to the receiving hopper is located above another material pipe and higher than the pumping mechanism.

[0014] In order to filter and screen the mined coal slime, the discharge port is connected to a linear vibrating screen through a first conveying pipe, a transportation device is provided on one side of the solid outlet of the linear vibrating screen, and the liquid outlet is connected to a solid-liquid separation device through a second conveying pipe, and a conveyor is provided at the solid discharge port, and the end of the conveyor extends above the transportation device.

[0015] The beneficial effects of the present invention are as follows: The present invention provides a coal-water separation and processing device for mining with a novel mud pump. The mud pump mechanism rotates a cam structure through a drive device. The cam portion alternately squeezes a flexible hose, utilizing the flexible hose's elastic deformation to create negative pressure, effectively drawing in residual mud from underground water tanks and coal slurry water sedimentation tanks (pits). This mechanical extrusion method achieves fluid transport and is highly adaptable to high-viscosity, particulate-laden mud. This effectively addresses the difficulties and inefficiencies in collecting residual mud in existing technologies, significantly improving the thoroughness of clearance operations and reducing the amount of water storage capacity occupied by residual mud. Secondly, the pumping mechanism has two output ports that extend into the receiving hopper and alternately connect to the discharge port, enabling the cyclical pumping of the coal slurry. This alternating operating mode avoids the blockage problem caused by the continuous transportation of highly viscous coal slurry in traditional conveying equipment, while also reducing continuous wear on the equipment and extending its service life. In addition, the coordination of the main drive cylinder, auxiliary drive cylinder, and reversing device makes the conveying process more controllable, ensuring the continuity and stability of coal slurry transportation and improving the efficiency of the entire coal-water separation process. The clearance equipment's travel mechanism, collection mechanism, and loading mechanism work together to achieve efficient excavation and loading of coal slurry. The slurry pump mechanism promptly collects residual slurry, preventing secondary pollution and resource waste. The pumping mechanism steadily delivers the slurry to subsequent processing equipment. These components work together to form a complete coal-water separation and treatment system, effectively addressing the pressure on coal (rock) slurry treatment caused by increased mine water inflow, reducing wear on the main drainage pump caused by coal slurry, lowering maintenance costs, and ensuring the normal operation of the mine drainage system.

DETAILED DESCRIPTION

[0018] Exemplary embodiments of the present disclosure will be described in greater detail below with reference to the accompanying drawings. It should be noted that these embodiments are provided so that the present disclosure can be more thoroughly understood, and the scope of the present disclosure can be accurately conveyed to those skilled in the art, and the present disclosure can be implemented in various forms, and should not be limited by the embodiments set forth herein.

[0019] EMBODIMENT The present embodiment discloses a mine coal-water separation treatment device with a new slurry pump, which combines the advantages of the prior art and has the following advantages: Figure 1The coal-water separation and treatment device for mines is based on the cleaning device 1 and integrates the subsequent separation equipment to form a complete underground coal slime treatment system. In this solution, the material transportation from the cleaning device 1 to the subsequent separation equipment and the collection of the coal slime remaining in the water bin are improved and optimized. The front end of the walking mechanism 11 is provided with a gathering mechanism 12, which can mine and collect coal slime, and the gathering mechanism 12 is connected to a feeding mechanism 13 extending toward the end of the device. By setting the feeding mechanism 13, the feeding mechanism 13 is connected to the gathering mechanism 12. The connection of the mechanism 12 can transport the coal slime collected by the gathering mechanism 12. A receiving hopper 14 is provided at the end of the walking mechanism 11, and the discharge port 131 of the feeding mechanism 13 is located above the receiving hopper 14 and within the area covered by the receiving hopper 14 in the vertical direction, ensuring that the transported coal slime is accurately discharged into the receiving hopper 14 at the discharge port 131. A discharge port 141 is provided at the end of the receiving hopper 14 away from the walking mechanism 11, and the coal slime is transported out of the clearing equipment 1 to the subsequent separation equipment for solid-liquid separation at the discharge port 141.

[0020] In this embodiment, combined with Figure 2 and Figure 3 The receiving hopper 14 serves as the transfer core, and a mud pump mechanism 15 is installed on its side. The pump body 151 of this mechanism has a circular inner cavity structure. The pump body 151 is connected to multiple feed ports 153. In this solution, two feed ports 153 are symmetrically arranged on the outside, and both feed ports 153 are arranged horizontally. A high-strength elastic hose 154 is fixed around the inner cavity wall. The two ends of the hose 154 are sealed and connected to the two feed ports 153, forming a closed conveying channel. Moreover, the outsides of the two feed ports 153 are connected to the outside of each other. One of the feed ports 153 is connected to the inside of the receiving hopper 14 through the feed pipe 155, which is used to transport the coal slurry to the receiving hopper 14. The other feed port 153 is connected to the underground water tank through the extended feed pipe 155, which is used to suck the coal slurry remaining in the underground water tank.

[0021] Based on the above structure, combined with Figure 3 and Figure 4The driving device 152 installed on the outside of the pump body 151 is an explosion-proof motor, the output end of which coaxially extends into the interior of the pump body and is connected to the cam structure, and the cam structure includes at least two cam portions 156. In this solution, the structure includes a triangular mounting plate 157 and three cam portions 156. The cam portions 156 are circular rollers, and the cam portions 156 are rotatably mounted on the three corners of the mounting plate 157 respectively. Moreover, the extension of the cam portion 156 relative to the rotation center exceeds the minimum distance from the rotation center to the hose 154. Specifically, when rotating, the minimum distance between the cam portion 156 and the inner wall of the pump body does not exceed 2 times the wall thickness of the hose 154, ensuring that when the cam portion 156 alternately squeezes the hose 154, it can at least make the inner wall of the hose 154 fit, forming a sealed space, thereby increasing the suction and discharge force of the coal slime. When the driving device 152 is running, two of the three cam portions 156 alternately squeeze the hose 154, and a sealed cavity 158 is formed between the two adjacent contacting cam portions 156, that is, there is always squeezing between the two cam portions 156 and the hose 154, and the mud is pushed to flow along the hose 154 as it rotates, thereby realizing efficient transportation of the residual mud in the underground water tank to the receiving hopper 14.

[0022] At the same time, combined Figure 4 A stirring assembly 17 is provided in the receiving hopper 14, including a drive shaft and circumferentially installed stirring blades. The drive shaft extends into the interior of the pump body and is connected to the output end of the drive device 152. It rotates synchronously to prevent the coal slime from settling and agglomerating, thereby improving the fluidity in the receiving hopper 14.

[0023] In this embodiment, the walking mechanism 11 is provided with a pumping mechanism 16. It should be noted that, in combination with Figure 3 and Figure 4The material pipe 155 connected to the receiving hopper 14 is positioned higher than the pumping mechanism 16 to prevent the coal sludge from flowing back. The pumping mechanism 16 is provided with two output ends, which extend into the receiving hopper 14 and alternately connect with the discharge port 141, so as to pump out the coal sludge in the receiving hopper 14 in a circular manner. The pumping mechanism 16 comprises two main drive cylinders 161, two auxiliary drive cylinders 162, a matching water tank 163 and a reversing device. The reversing device can use an electromagnetic reversing valve in conjunction with a pipeline to control the water inlet and outlet of the two main drive cylinders 161. The piston rods of the main drive cylinder 161 and the auxiliary drive cylinder 162 are connected by a connecting structure. The reversing device in the water tank 163 can control the alternating extension and retraction of the two main drive cylinders 161. The feeding ends of the two auxiliary drive cylinders 162 are connected to the double-hole plate 164 in the receiving hopper 14 through pipes. Two connecting holes are provided on the double-hole plate 164. A connecting pipe 165 connected to the discharge port 141 is also provided inside the receiving hopper 14. The connecting pipe 165 is driven by a swing cylinder 166 through a swing arm 167. Two swing cylinders 166 are provided, which drive the swing arm 167 to swing in two directions respectively, and then can cyclically dock with the two holes of the double-hole plate 164. When the swing cylinder 166 drives the connecting pipe 165 to connect with one of the auxiliary drive cylinders 162, the auxiliary drive cylinder 162 presses out the sucked coal slime under the action of the main drive cylinder 161. At the same time, the other auxiliary drive cylinder 162 and the matching main drive cylinder 161 perform a suction action to suck the coal slime in the hopper 14 into the cylinder body. Then, the swing cylinder 166 is controlled to make the connecting pipe 165 connect with the auxiliary drive cylinder 162 that sucks the coal slime. The reversing device controls the reversal of the two main drive cylinders 161, and the two auxiliary drive cylinders 162 alternately perform suction and discharge actions to achieve cyclical continuous transportation.

[0024] It should be noted that after the excavation is completed, there may be residual coal slime in the first feed pipe 2, but the receiving hopper 14 is in an empty state, and it is not easy to pump out the coal slime in the first feed pipe 2. The swing cylinder 166 can be controlled to drive the connecting pipe 165 to connect with any channel of the double-hole plate 164. At this time, the main drive cylinder 161 and the auxiliary drive cylinder 162 connected thereto contract to suck the coal slime in the first feed pipe 2 into the receiving hopper 14.

[0025] In this embodiment, combined with Figure 5The discharge port 141 is connected to the linear vibrating screen 3 through the first feed pipe 2, and the coal slime is transported to the linear vibrating screen 3 through the pumping mechanism 16. The screen surface is arranged at an angle to accelerate separation. A transport device 4 is set on the solid outlet side. The transport device 4 uses a rail-type transport vehicle, which is powered by a battery pack. First, the coal slime solids that pass through the linear vibrating screen 3 fall into the rail-type transport vehicle through the solid outlet and are transported out of the well. The liquid after screening still contains a lot of coal slime, so the liquid outlet of the linear vibrating screen 3 is connected to the solid-liquid separation device 6 through the second feed pipe 5 to perform a second screening of the coal slime. A conveyor 7 is provided at the solid discharge port of the solid-liquid separation device 6. The end of the conveyor 7 extends to the top of the transport device 4, so that the solid coal slimes produced by the two separation devices are collected and transported out, and the liquid is reused in the underground system after treatment, forming a complete coal-water separation process.

[0026] In addition, the gathering mechanism 12 installed at the front end of the walking mechanism 11 includes excavation equipment and gathering equipment. The excavation equipment is assembled at the front end of the walking mechanism 11 and adopts a multi-axis hydraulic drive mechanical arm, which includes a base rotation axis, a boom pitch axis, a small arm telescopic axis and a bucket flip axis. A bucket is installed at the end for excavating coal slime, and the gathering equipment is installed across the front of the walking mechanism 11. Its gathering bin is a cylindrical trough structure with an opening at the front end. Two gathering shafts are symmetrically arranged inside. Continuous spiral blades are welded on the outside of the shaft body. The dual-motor drive mechanism in the middle of the bin body rotates synchronously in the opposite direction, and the coal slime poured by the excavation mechanism can be gathered to the middle of the bin body. The middle part of the collecting bin extends toward the side of the traveling mechanism 11 to form a temporary storage bin, which is used to buffer and temporarily store the gathered coal slime. Secondly, the feeding mechanism 13 includes a feeding pipe with a spiral mechanism arranged inside. The bottom end of the spiral mechanism extends into the temporary storage bin, and the upper end extends to the top discharge port 131. The coal slime is transported obliquely backward and upward by the motor drive, and finally falls into the receiving hopper 14 located at the bottom of the discharge port 131.

[0027] The control system of the present invention preferably locates the clearing device 1 and constructs a running map through the Gamapping algorithm, uploads the acquired three-dimensional geographic spatial information to the Free RTOS system, identifies the shape and position of the coal slime section through the recognition camera and the non-contact distance sensor, and the control system collects data based on the recognition camera and the non-contact distance sensor, establishes an FCN network adapted to the distance data, and constructs an excavation grid map of the excavation mechanism based on the Gampping algorithm, sends control instructions to the clearing device 1 through the underlying control panel, controls the clearing device to perform coal slime excavation according to the running map and the excavation grid map, and establishes real-time communication between the clearing device 1 and each communication node based on Ethernet communication to realize remote control of the entire device.

[0028] During operation, the control system is preferably based on the difference e between the real-time density of the detected coal slime and the target density ρst, and the maximum difference and minimum difference are preset according to the on-site environment. When the difference is greater than the maximum difference, the control system dilutes the coal slime density by selectively adding constant pressure water. When the difference is less than the minimum difference, the calculated density deviation e and the deviation change rate ec are used as input variables of the fuzzy controller, and the corresponding fuzzy control quantities Δkp, Δki, and Δkd are output. They are superimposed with the initial parameters to obtain real-time working parameters kp+Δkp, ki+Δki, and kd+Δkd, which are input into the PID controller as initial variables. At the same time, e is input into the step control, and the deviation interval is divided. The correction value is obtained through the Γ(e) link, and a step control signal for reducing the water injection amount is output.

[0029] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
