Description

Technical Field

[0001] This utility model belongs to the field of underground gas drainage technology in coal mines, specifically relating to an integrated gas-water-slag treatment device. Background Technology

[0002] The mine's gas drainage pipeline is connected to a drainage mechanism, which is mainly used to collect water and sludge from the gas drainage pipeline and discharge them. The existing drainage mechanism uses a jack rod with a sealing ball connected to its end to discharge the water and sludge stored within. Because the float has a certain weight, the jack rod is prone to deformation due to prolonged use or external forces during transport, leading to a poor seal between the sealing ball and the sealing opening, resulting in air leakage.

[0003] Some of the related devices are complex in structure, and their manufacturing and maintenance are troublesome, which affects their efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide an integrated gas-water-slag treatment device with a long service life and good sealing performance.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] An integrated gas-water-slag treatment device includes a gas-gathering chamber and a water storage chamber, which are separated by a partition. The gas-gathering chamber is located above the water storage chamber. An exhaust port is provided on the top of the gas-gathering chamber, connected to a gas collection station via an exhaust pipe. A drain pipe from the gas-gathering chamber leads to the water storage chamber through the partition, and a sealing plate B is provided at the outlet of the drain pipe. A slag discharge port is provided at the bottom of the water storage chamber, and a sealing plate A is provided at the slag discharge port. The device is characterized in that: the gas-gathering chamber has at least two air inlets; a sleeve is provided on the upper part of the water storage chamber, with a piston inside the sleeve. The piston's vertical movement is limited by the sleeve. The lower end of the piston is hinged to a vertically downward guide rod via a limiting plate. A float is provided on the guide rod and can move vertically up and down; a return air pipe is provided on the upper part of the top wall of the sleeve, connecting to the upper part of the gas-gathering chamber; a vent A is provided on the sleeve, leading to the wall of the water storage chamber; a vent B is also provided on the sleeve, connecting the sleeve and the water storage chamber.

[0007] further:

[0008] The bottom of the water storage chamber is equipped with a base, which restricts the swing of the guide rod but does not restrict the rise of the guide rod.

[0009] A limiting plate is connected below the piston via a connecting rod, which passes through the bottom hole of the sleeve; the piston diameter matches the inner diameter of the sleeve; the diameter of the connecting rod is smaller than the diameter of the bottom hole of the sleeve.

[0010] When using two air inlets, they are arranged in a staggered parallel configuration and connected to the gas extraction holes respectively.

[0011] The sealing plate A and the sealing plate are connected to the slag outlet and the water outlet respectively via shafts. Under negative pressure, they tightly adhere to and seal the slag outlet and the water outlet respectively.

[0012] Both the slag outlet and the water outlet are oblique cuts with an included angle of 10-30°.

[0013] The bottom of the water storage chamber is provided with an inclined plate, and the slag discharge port is located at the end of the inclined plate.

Detailed Implementation

[0021] like Figure 1 , 2 As shown in Figures 3 and 4, an integrated gas-water-slag treatment device includes a gas-gathering chamber 7 and a water storage chamber 13, which are separated by a partition 8. Each side of the gas-gathering chamber 7 has an air inlet 4, and the top of the gas-gathering chamber 7 has an exhaust outlet 5, with a drain pipe 3 at the bottom. The two air inlets 4 are connected to gas extraction holes respectively; the exhaust outlet 5 is connected to a gas collection station via an exhaust pipe, and the gas entering the gas-gathering chamber 7 from the air inlets 4 is discharged into the gas collection station through the exhaust outlet 5.

[0022] The drain pipe 3 of the gas-gathering chamber 7 passes through the partition 8 and enters the water storage chamber 13, allowing water and coal slag entering the gas-gathering chamber 7 to be discharged into the water storage chamber 13. The drain pipe 3 has an "L" shaped structure, which serves to slowly discharge water and coal slag.

[0023] A sealing plate B is installed at the end of drain pipe 3. Sealing plate B is connected by a shaft, and a spring can be added if necessary to automatically seal the outlet of drain pipe 3. When the weight of water and coal slag reaches a certain level, it can force open sealing plate B. The outlet of drain pipe 3 adopts a beveled design (generally with an acute angle of 10-30° to the vertical). This allows coal sludge (slag) to easily enter and exit, resulting in good drainage and slag removal, and solving the problem of coal sludge and slag clogging the outlet and causing air leakage.

[0024] In this utility model, the outlet of the drain pipe 3 and the slag discharge port on the slag collection hopper 19 are both designed with oblique cuts.

[0025] A float 2 is installed inside the water storage chamber 13, and a sleeve 10 is installed above the float 2. The shape of the float 2 can be selected as spherical or cylindrical, and the size and weight of the float 2 can be selected. The sleeve 10 is fixed in the water storage chamber 13 by a support plate 16. A base is provided at the bottom of the water storage chamber 13, and a guide rod 11 that can move up and down is vertically installed on the base. The base restricts the swing of the guide rod 11, but does not restrict the rise of the guide rod. The float 2 is axially sleeved on the guide rod 11 and can move up and down along the guide rod 11. A piston 17 is installed inside the sleeve 10, and the piston 17 can move up and down inside the sleeve 10. A limiting plate 18 is connected to the connecting rod 20 below the piston 17. The connecting rod 20 passes through the bottom hole of the sleeve, and the guide rod 11 is hinged to the limiting plate 18. The float 2 rises under the buoyancy of the water, pushing the piston 17 to move upward.

[0026] The diameter of piston 17 matches the inner diameter of sleeve 10, thus forming a seal around sleeve 10; the diameter of connecting rod 20 is smaller than the diameter of bottom hole of sleeve, and there is a gap between connecting rod 20 and bottom hole of sleeve.

[0027] The side wall of the water storage chamber 13 is provided with a vent hole A9 to allow the inside of the sleeve 10 to be vented to the outside. The sleeve 10 is provided with a vent hole B19 for allowing the sleeve 10 to be vented to the water storage chamber 13; the top of the sleeve 10 is provided with a return air pipe 6, the upper opening of the return air pipe 6 is located at the upper part of the air gathering chamber 7, and the arrangement of the return air pipe 6 allows the inside of the sleeve 10 to be vented to the air gathering chamber 7.

[0028] The bottom of the water storage chamber 13 is a slag discharge port, which is sealed by sealing plate A.

[0029] The bottom of the water storage chamber is provided with an inclined plate 14, and the slag discharge port is located at the end of the inclined plate 14.

[0030] A processing hole 12 is provided on one side of the bottom of the water storage chamber.

[0031] The water storage chamber is equipped with an observation window 15.

[0032] Both the water storage chamber 13 and the float 2 can be made of PVC material, which has the advantages of corrosion resistance, light weight, antistatic properties, and non-deformation. The sleeve 10 and the piston 17 can be made of stainless steel or other wear-resistant materials.

[0033] Figure 5 —8 shows four structural diagrams of the gas-gathering chamber.

[0034] Figure 5 This is the case where the two air intakes 4 are directly opposite each other. Figure 6 —8 represents the case where the two air intakes are misaligned and parallel, where: Figure 6 This refers to the case where the two air inlets 4 are positioned parallel to each other and offset from the outer edge of the air-gathering chamber. Figure 7 This refers to the case where the two air inlets 4 are positioned parallel and offset on the inside of the air-gathering chamber. Figure 8 The two air inlets 4 are positioned in a staggered and parallel configuration in the middle of the gas-gathering chamber. This staggered and parallel configuration facilitates the air intake of the gas-gathering chamber 7, which drives the coal slime (slag) to rotate and settle, and allows it to be discharged into the water storage chamber 13 in a timely manner.

[0035] The working principle of this utility model is as follows: Figure 4As shown, gas, water, and coal slag (sludge) enter the gas-gathering chamber 7 through the air inlet 4. The gas is drawn away from the exhaust port 5. Due to the action of the exhaust fan at the air inlet 4, the gas-gathering chamber 7 is under negative pressure. At this time, the return air pipe 6 connects to the gas-gathering chamber 7, and the vent B19 connects the gas-gathering chamber 7 and the water storage chamber 13. Therefore, the water storage chamber 13 is under negative pressure. The outlet of the drain pipe 3 is sealed by the sealing plate B, and the slag discharge port is sealed by the sealing plate A. Both sides of the sealing plate B are under negative pressure, and the air pressure is balanced. Under the action of its own weight, water and coal slag (sludge) enter the water storage chamber 13 through the drain pipe 3. The inside of the sealing plate A is under negative pressure, and the outside is under atmospheric pressure. The air pressure on both sides is unbalanced, so it is blocked by the slag discharge port. As more water and coal slag (mud) enter the water storage chamber 13, the float 2 begins to rise under the action of buoyancy, thereby pushing the piston 17 upward. When the piston 17 rises and blocks the vent hole B19 (by sealing the periphery of the sleeve 10 with the help of the piston 17), the vent hole A9 is opened at the same time. With the help of the gap between the connecting rod 20 and the sleeve 10, the interior of the water storage chamber 13 becomes atmospheric pressure. The outlet of the drain pipe 3 is sealed by the negative pressure above the sealing plate B and the atmospheric pressure below, so the outlet is blocked. At the same time, the inside and outside of the sealing plate A are both atmospheric pressure. Under the action of its own weight, the water and coal slag (mud) break through the sealing plate A and are discharged through the slag discharge port.

Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
