Description

Technical Field

[0001] This application relates to the field of water treatment, and particularly to a mine water inrush treatment device. Background Art

[0002] Currently, mine water inrush, that is, mine wastewater, is the general term for natural leaching water in the mine, ore dressing wastewater, overflow water from the dike of ore dressing waste residue, and leaching water from the accumulation of ore slag. The pollutants in mine wastewater are mainly divided into solid pollutants such as ore slag and debris particles, and acid-base substances such as sulfur leached from minerals. The sewage discharged during underground mining, especially hydraulic coal mining and water-sand filling mining methods, cannot be ignored. Therefore, the water generated during the mine mining process needs to be purified before being discharged to the outside to avoid environmental pollution.

[0003] Currently, when treating solid pollutants in the inrush water, a filtering device is usually used to filter out the solid pollutants in the inrush water. The filtering device generally includes a filter box and at least two filter plates suspended in the filter box. The two filter plates are arranged at intervals up and down, and can perform multi-stage filtering on solid pollutants.

[0004] The above prior art solutions have the following defects: When filtering solid pollutants through the filter plate, the pollutants stay on the surface of the filter plate. Since the discharge speed of the filter residue is slow, the filter residue accumulates on the surface of the filter plate and easily clogs the filter holes. When cleaning the clogged filter holes, it is necessary to stop work, resulting in a reduction in the sewage treatment efficiency. Utility Model Content

[0005] This application provides a mine water inrush treatment device in order to continuously filter a large amount of solid pollutants in a large amount of continuous mine water inrush.

[0006] The above technical objectives of this application are achieved through the following technical solutions:

[0007] A mine water inrush treatment device includes a sedimentation tank, a first sewage discharge pipe fixedly connected to the bottom of the sedimentation tank and communicating with the sedimentation tank, a first liquid discharge pipe fixedly connected to the upper part of the sedimentation tank and communicating with the sedimentation tank, a mud-water separation tank fixedly connected to the lower end of the first liquid discharge pipe at the top and communicating with the first liquid discharge pipe through a connecting pipe, a second sewage discharge pipe fixedly connected to the bottom of the mud-water separation tank and communicating with the inside of the mud-water separation tank, two sealing plates respectively hinged to one end of the first sewage discharge pipe away from the sedimentation tank and hinged to one end of the second sewage discharge pipe away from the mud-water separation tank, and two locking members respectively fixedly arranged on the sealing plates and the sewage discharge pipes for connecting the sealing plates and the sewage discharge pipes. A sealing gasket is fixedly arranged on the plate surface of the sealing plate facing the sewage discharge pipe, and the plate surface area of the sealing plate is larger than the pipe orifice area of the sewage discharge pipe.

[0008] By adopting the above technical solution, compared with the conventional vibrating screen for treating the gushing water, a large amount of continuous gushing water quickly separates the mud from the solid pollutants in the sedimentation barrel. As the mud content in the sedimentation barrel increases, the mud flows from the first drain pipe to the mud-water separation box. After further treatment in the mud-water separation box, the purified water can be discharged through the second drain pipe. The discharge end of the drain pipe can be closed by the locking member and the sealing plate, so that the mud will not leak through the drain pipe during the process of settling the solid pollutants in the sedimentation barrel.

[0009] Optionally, the sealing plate is bent away from the side hinged with the sewage pipe to form an extension plate, and the bending direction of the extension plate is opposite to the pipe opening of the sewage pipe;

[0010] The locking member includes a fixing member fixed to the outer wall of the sewage pipe, a shell fixed to the extension plate and having closed ends at both ends, a movable plate movably arranged between the two ends of the shell, a spring in an extended state with its two ends respectively abutting against the movable plate and the upper end of the shell, and a plug-in rod passing through the two ends of the shell and fixed to the movable plate, wherein the end of the plug-in rod close to the movable plate is a hemispherical surface and can be plugged into the fixing member.

[0011] By adopting the above technical solution, the overall structure of the locking piece is simple and easy to operate, which is convenient for the staff to open and close the end of the sewage pipe by operating the locking piece.

[0012] Optionally, reinforcing ribs are fixedly connected to the plate surface of the sealing plate facing away from the sealing gasket.

[0013] By adopting the above technical solution, the reinforcing ribs can keep the sealing plate as flat as possible, which is conducive to closing the sewage pipe.

[0014] Optionally, the sedimentation tank comprises a cylindrical section with a closed end at the top and a funnel section fixedly connected to the lower end of the cylindrical section, and the bottom of the funnel section is fixedly connected to one end of the first sewage pipe;

[0015] A mesh plate is fixedly connected to the inner wall of the cylinder section, and the mesh plate is spaced apart from the top of the cylinder section. A liquid inlet pipe is fixedly connected to the outer wall of the cylinder section, and the liquid inlet pipe is communicated with the inside of the cylinder section and is located below the mesh plate.

[0016] By adopting the above technical solution, the mesh plate can effectively prevent solid pollutants from entering the first liquid discharge pipe, thereby facilitating a large amount of solid pollutants to be concentrated and precipitated at the bottom of the funnel section.

[0017] Optionally, a spiral guide plate is fixedly connected to the inner wall of the cylindrical section, and the upper end of the guide plate is lower than the liquid inlet pipe.

[0018] By adopting the above technical solution, after the solid pollutants in the gushing water enter the sedimentation bucket, the solid pollutants can be effectively guided, so that the solid pollutants settle into the funnel section by their own gravity.

[0019] Optionally, the gushing water treatment equipment further includes a conveyor. The discharge ends of the first sewage discharge pipe and the second sewage discharge pipe are both suspended above the conveying surface of the conveyor, and the sealing plate is spaced from the conveying surface of the conveyor.

[0020] By adopting the above technical solution, using one conveyor can effectively control the overall cost of the treatment equipment. The conveyor transports the solid pollutants away, which is faster than manual transportation and further facilitates the centralized treatment of a large amount of solid pollutants.

[0021] Optionally, multiple legs are provided at the bottom of the mud-water separation tank. A flow dividing plate is fixedly connected inside the mud-water separation tank. The flow dividing plate is an arc-shaped plate and its arc protruding surface faces the first liquid discharge pipe, and the arc opening of the flow dividing plate faces the second liquid discharge pipe.

[0022] By adopting the above technical solution, the legs support the mud-water separation tank to facilitate the installation of the second sewage discharge pipe. The arc protruding surface of the flow dividing plate can block the slurry, so that the slurry flows along the arc protruding surface of the flow dividing plate to the bottom of the mud-water separation tank, reducing the violent disturbance formed after the slurry enters the mud-water separation tank, and facilitating the formation of supernatant liquid in the mud-water separation tank.

[0023] Optionally, the bottom of the mud-water separation tank is inclined upward in the direction of the connection line between the first liquid discharge pipe and the second liquid discharge pipe, and the second sewage discharge pipe is connected to the lower part of the bottom of the mud-water separation tank.

[0024] By adopting the above technical solution, it is beneficial to concentrate the precipitation of the slurry to the bottom of the mud-water separation tank.

[0025] Optionally, a chemical agent tank is fixedly arranged at the top of the mud-water separation tank, and the chemical agent tank is communicated with the inside of the mud-water separation tank.

[0026] By adopting the above technical solution, the chemical agent tank stores the sewage treatment agent to remove particulate matter and acid-base substances.

[0027] In summary, the present application has the following technical effects:

[0028] 1. By providing a sedimentation bucket, a first sewage discharge pipe, a first liquid discharge pipe, a mud-water separation tank, a second sewage discharge pipe, a sealing plate, and a locking member, the discharge end of the sewage discharge pipe can be closed by the locking member and the sealing plate, so that the slurry can be prevented from leaking through the sewage discharge pipe during the process of precipitating solid pollutants in the sedimentation bucket;

Detailed Description of the Embodiment

[0036] The following further describes the present application in detail with reference to the drawings.

[0037] The embodiment of the present application discloses a mine water inrush treatment device. Refer to Figures 1 to 3, The mine water treatment equipment includes a sedimentation tank 1, a first sewage discharge pipe 2 fixedly connected to the bottom of the sedimentation tank 1 and communicating with the inside of the sedimentation tank 1, a sealing plate 3 hinged to the discharge end of the first sewage discharge pipe 2, a locking member 4 fixedly connected to the sealing plate 3 and detachably and fixedly connected to the discharge end of the first sewage discharge pipe 2, a conveyor 5 arranged below the discharge end of the first sewage discharge pipe 2, a first liquid discharge pipe 6 fixedly connected to the upper part of the sedimentation tank 1 and communicating with the inside of the sedimentation tank 1, a mud-water separation tank 7 fixedly connected and communicated with the lower end of the first liquid discharge pipe 6, a second sewage discharge pipe 8 fixedly connected to one end of the bottom of the mud-water separation tank 7 and communicating with the inside of the mud-water separation tank 7, and a second liquid discharge pipe 9 fixedly connected to the upper part of the mud-water separation tank 7 and communicating with the inside of the mud-water separation tank 7. In this embodiment, a sealing plate 3 and a locking member 4 are also installed on the discharge end of the second sewage discharge pipe 8. Augers are provided inside both the first sewage discharge pipe 2 and the second sewage discharge pipe 8, and motors for the operation of the augers are installed at the ends of the sewage discharge pipes far from the sedimentation tank 1 and the mud-water separation tank 7. The outer surfaces of the two augers are respectively in contact with the inner walls of the two sewage discharge pipes. When the sealing plate 3 is in a vertical state, the lower part of the sealing plate 3 always hangs above the conveying surface of the conveyor 5.

[0038] Combined with Figure 1 , Figure 2 , the sedimentation tank 1 includes a cylindrical section 11 and a funnel section 12 fixedly connected to the lower end of the cylindrical section 11. The upper end of the cylindrical section 11 is a closed end, and a pipe head 13 is fixedly connected to the lower end of the funnel section 12 for connecting to the end of the first sewage discharge pipe 2. A plurality of support rods 14 vertically arranged with their upper ends fixedly connected to the outer wall of the funnel section 12, a mesh plate 15 horizontally arranged inside the cylindrical section 11 and spaced from the top of the cylindrical section 11, a liquid inlet pipe 16 fixedly connected to one end of the outer wall of the cylindrical section 11 and communicating with the inside of the cylindrical section 11, and a guide plate 17 spirally fixedly connected to the inner wall of the cylindrical section 11 with its top end lower than the liquid inlet pipe 16 are also provided on the sedimentation cylinder. The end of the liquid inlet pipe 16 communicating with the cylindrical section 11 is lower than the mesh plate 15.

[0039] The mine water gushing out enters the sedimentation tank 1 from the end of the liquid inlet pipe 16 far from the cylindrical section 11. Under the action of the spiral guide plate 17, the solid pollutants in the gushing water can be effectively guided after entering the sedimentation tank 1, so that the solid pollutants settle into the funnel section 12 by their own gravity. Compared with using a conventional vibrating screen to treat the gushing water, a large amount of continuous gushing water can quickly separate the mud and solid pollutants in the sedimentation tank 1. As the mud content in the sedimentation tank 1 increases, the mud flows from the mesh plate 15 to the mud-water separation tank 7 through the first liquid discharge pipe 6. The discharge end of the first sewage discharge pipe 2 can be closed by the locking member 4 and the sealing plate 3, so that the mud can be prevented from leaking through the first sewage discharge pipe 2 during the process of sedimenting solid pollutants in the sedimentation tank 1. In this embodiment, the discharge end of the sewage discharge pipe is square tubular, and the square pipe is convenient for installing the sealing plate 3.

[0040] Referring toFigure 3 , the plate surface area of the sealing plate 3 is larger than the area of the sewage pipe nozzle. In this embodiment, the sealing plate 3 is a rectangular plate and the length of the sealing plate 3 is greater than the length of the sewage discharge end of the sewage pipe. The sealing plate 3 is hinged to the outer wall of the sewage pipe through a hinge. A sealing gasket (not shown in the figure) is fixedly connected to the plate surface of the sealing plate 3 that closes the sewage pipe. A plurality of reinforcing ribs 31 are fixedly arranged on the plate surface of the sealing plate 3 away from the sealing gasket, so that the sealing plate 3 can be kept as flat as possible, which is beneficial to closing the sewage pipe. One side of the sealing plate 3 away from the hinge is formed into an extension plate 32 through bending. When the sealing plate 3 closes the sewage pipe, the bending direction of the extension plate 32 is opposite to the orientation of the sewage pipe nozzle, and the extension plate 32 is arranged at an interval from the sewage pipe. The locking member 4 is fixedly arranged on the extension plate 32 and is located within the right-angle opening formed by the sealing plate 3 and the extension plate 32.

[0041] Refer to Figure 3 , the locking member 4 includes a fixing member 41 fixedly arranged on the outer wall of the sewage pipe, a housing 42 vertically and fixedly arranged on the extension plate 32 and not closed at both the upper and lower ends, a movable plate 43 movably arranged within the housing 42 and located at the lower end of the housing 42, a spring 44 arranged within the housing 42 and located on the upper plate surface of the movable plate 43, and a plugging rod 45 movably passing through both ends of the housing 42 and fixedly connected to the movable plate 43. The two ends of the spring 44 are respectively abutted against the upper end of the housing 42 and the movable plate 43, and the spring 44 is sleeved outside the plugging rod 45, so as to ensure that the spring 44 can be smoothly extended after being compressed. The length of the plugging rod 45 is greater than the length of the housing 42. In this embodiment, the housing 42 is made of channel steel, and the notch of the channel steel faces the extension plate 32. The lower end of the plugging rod 45 is processed into a hemispherical shape, and a jack is opened on the fixing member 41. The lower end of the plugging rod 45 can be inserted into the jack. In order to improve the stability of the sealing plate 3 in closing the sewage pipe, at least two locking members are provided. The fixing member 41 can be set as a fixing block or a fixing strip.

[0042] When it is necessary to discharge solid pollutants, the staff can pull the upper end of the plugging rod 45 upward to pull the plugging rod 45 out of the fixing member 41, so that the sealing of the discharge end of the sewage pipe by the sealing plate 3 can be released; when it is necessary to close the discharge end of the sewage pipe, the staff rotates the sealing plate 3 towards the discharge end of the sewage pipe and inserts the plugging rod 45 into the fixing member 41. The spring 44 in the extended state can stably hold the movable plate 43 and make the plugging column stably inserted into the fixing member 41, which is beneficial to the sealing plate 3 to close the discharge end of the sewage pipe.

[0043] Refer to Figure 4, the lower end of the first drain pipe 6 is connected to one side of the top of the mud-water separation box 7, and the second drain pipe 9 is connected to the upper part of the mud-water separation box 7 away from the side wall of the first drain pipe 6. A plurality of legs 71 are provided at the bottom of the mud-water separation box 7, the legs 71 are vertically arranged and the upper ends are fixedly connected to the bottom of the mud-water separation box 7, and the mud-water separation box 7 is suspended above the ground through the legs 71, providing installation space for the second sewage pipe 8. A plurality of diverter plates 72 are also provided inside the mud-water separation box 7, and the two ends of the diverter plates 72 are respectively fixedly connected to the two opposite inner walls of the mud-water separation box 7, the diverter plates 72 are arc-shaped plates and the arc-shaped opening faces away from the lower end of the first drain pipe 6, and the plurality of diverter plates 72 are arranged at intervals along the direction of the line from the first drain pipe 6 to the second drain pipe 9.

[0044] When the mud flows into the mud separation box from the first drainage pipe 6, the arc-shaped protruding surface of the diverter plate 72 can block the mud, so that the mud flows along the arc-shaped protruding surface of the diverter plate 72 toward the bottom of the mud-water separation box 7, reducing the violent disturbance formed after the mud enters the mud-water separation box 7, which is conducive to the formation of supernatant liquid in the mud-water separation box 7. The supernatant liquid is discharged through the second drainage pipe 9, and the gushing water treatment work can be completed.

[0045] Reference Figure 4 The bottom of the mud-water separation box 7 is tilted, and its tilting direction is tilted upward from the first drain pipe 6 to the second drain pipe 9. The second sewage pipe 8 is connected to the lower part of the tilted bottom of the mud-water separation box 7. The conveyor 5 is arranged between the sedimentation barrel 1 and the mud-water separation box 7. The second sewage pipe 8 is staggered with the first sewage pipe 2, and the discharge end of the second sewage pipe 8 is also suspended above the conveyor 5, so that both the first sewage pipe 2 and the second sewage pipe 8 can use the conveyor 5 when discharging solid pollution, effectively reducing the use cost.

[0046] Reference Figure 4 A reagent box 73 is arranged on the top surface of the mud-water separation box 7. The reagent box 73 is arranged close to the first drain pipe 6. The reagent box 73 contains reagents for sewage treatment, thereby removing particulate matter and acidic and alkaline substances.
