Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and in particular to a device for treating sludge in underground mines. Background Technology

[0002] The silt in the mine is usually related to mining activities, natural geological processes and environmental factors. During open-pit mining, when the topsoil and rock are stripped away, a large amount of loose material is exposed and formed into fine-grained mud and sand by rainwater. Underground mining may cause surface collapse or fissures, leading to groundwater seepage and the accumulation of silt and sand. Tailings or waste rock piles after ore processing form mud under the erosion of rainwater.

[0003] There is a patent application with publication number CN109574433B entitled "A Municipal Sludge Treatment Device and its Treatment Method". The municipal sludge treatment device includes a box body. A motor is fixedly connected to the top of the box body. A rotating shaft is fixedly connected to the output shaft of the motor. The bottom end of the rotating shaft extends into the box body. Multiple stirring blades are welded to the outside of the rotating shaft. Connecting pipes are fixedly connected to both sides of the box body. The top ends of the two connecting pipes are connected to the same air box. The air box is fixedly installed on one side of the top of the box body. An air pump is fixedly connected to the top of the air box. The air outlet of the air pump extends into the air box. Multiple horizontally arranged first heating rods are fixedly connected to the inner wall of the air box. A liquid injection hole is provided on one side of the top of the air box. A first plug is installed in the threaded part of the liquid injection hole. The design is reasonable and can fully agitate the sludge in the box body, so that the microbial stock solution can be fully mixed into the sludge, reducing the organic matter content in the sludge. It can also dry the sludge with high drying efficiency.

[0004] While the aforementioned existing technologies can agitate municipal sludge and reduce its organic content, the sludge in the well contains montmorillonite. The presence of montmorillonite particles in the sludge increases its viscosity. After the sludge stratifies, a transition layer is formed between the sludge and the upper water layer. Due to the high viscosity of the sludge, some particles in the transition layer cannot successfully float to the surface of the sludge, and even agitation cannot improve the treatment effect. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a mining area underground sludge treatment device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: Design a mine underground sludge treatment device, including a composting bed, a frame, and a water pump, with the water pump located on the frame and the frame located on one side of the composting bed: The upper inner side of the frame is provided with a screw structure, and a connecting plate is connected to the screw structure.

[0015] Preferably, baffles are connected to both sides of the container, and the baffles are secured to the support frame.

[0016] The present invention proposes an underground sludge treatment device for mining areas, which has the following advantages: The device injects sludge into a composting bed, allows it to stand, then extracts the liquid from the upper layer and performs preliminary treatment on the extracted water.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0027] Example 1, referring to Figure 1-4 A mining underground sludge treatment device includes a composting bed 1, a frame 2, and a water pump 3, with the water pump 3 located on the frame 2, which is located on one side of the composting bed 1. A screw structure is provided on the upper inner side of the frame 2, and a connecting plate 9 is connected to the screw structure. The screw structure includes a stepper motor 7 installed on the outer side of the frame 2. A threaded rod 4 is installed at the end of the output shaft of the stepper motor 7, and a threaded sleeve 8 is installed on the threaded rod 4. The connecting plate 9 is fixed on the threaded sleeve 8, and the water inlet pipe of the water pump 3 passes through a reserved hole on the connecting plate 9 and extends to the inner side of the conical barrel 11.

[0028] A conical barrel 11 is fixed to the lower end of the connecting plate 9 via an electric telescopic rod 10. Two actuating plates 16 are symmetrically arranged on one side wall of the conical barrel 11. A support frame 15 is fixed to one side of the conical barrel 11. A holding box 26 is fixed to the inner side of the support frame 15. Baffles 14 are connected to both sides of the holding box 26. The baffles 14 are locked onto the support frame 15. Fly ash slurry is contained in the holding box 26. An L-shaped flow channel 19 is opened at the upper inner side of the actuating plate 16. The flow channel 19 is connected to the inside of the holding box 26 through a conveying pipe 13. An electrically controlled valve is installed on the conveying pipe 13.

[0029] Furthermore, the water inlet pipe of the water pump 3 extends to the inside of the conical barrel 11. Both the upper and lower ends of the conical barrel 11 are open, and the conical barrel 11 is wider at the top and narrower at the bottom. Multiple layers of filter cloth 25 are fixed at the bottom of the conical barrel 11.

[0030] The sludge collected underground was injected into compost bed 1. After a period of settling, the sludge was separated into layers, with the lower layer being sludge and the upper layer being water. Because the sludge in the mine contained montmorillonite, the sludge was very sticky, which was not conducive to the subsequent treatment of the sludge.

[0031] To this end, a frame 2 is installed on one side of the compost bed 1, and a stepper motor 7 is installed on one side of the frame 2. When the stepper motor 7 is powered on, it drives the threaded rod 4 in the middle to rotate. A threaded sleeve 8 is installed on the outside of the threaded rod 4, and the threaded sleeve 8 and the top of the frame 2 are provided with guide grooves for limiting the movement of the threaded sleeve 8 along the axial direction of the threaded rod 4. At the same time, it is fixed to one side of the threaded sleeve 8 by a connecting plate 9, and the connecting plate 9 is connected to a cone at the lower end by an electric telescopic rod 10. The conical barrel 11 is wider at the top and narrower at the bottom. The position and height of the conical barrel 11 are adjusted by the electric telescopic rod 10, so that the lower half of the conical barrel 11 extends into the upper layer of sludge. The water pump 3 is started, and the water pump 3 draws water out of the compost bed 1. During this process, the position of the conical barrel 11 can be linearly moved through the threaded sleeve 8, constantly changing its position and adjusting the water pumping control. At the same time, the bottom of the conical barrel 11 is compositely bonded with a filter cloth 25 to ensure that the sludge is not drawn out during the water pumping process.

[0032] To further address the viscosity of the sludge, a container 26 is installed on one side of the conical bucket 11. Fly ash slurry is added to the inside of the container 26. If fly ash is added directly to the viscous sludge, it will cause the fly ash to float and agglomerate, forming localized enrichment areas. Therefore, the fly ash slurry needs to be mixed in the container 26 beforehand. When the agitator 16 extends into the sludge, the electric valve on the conveying pipe 13 between the container 26 and the agitator 16 is activated. After the valve is activated, the fly ash slurry flows from the channel 1... 9 leaks out and directly enters the bottom of the sludge. At the same time, since the agitator plate 16 is connected to the side wall of the conical barrel 11, the agitator plate 16 moves in the sludge as the conical barrel 11 moves. On the one hand, it can fully and evenly inject the fly ash slurry into all parts of the sludge. On the other hand, the agitator plate 16 can slowly contact the sludge during its movement, thus achieving a stirring effect. Compared with traditional high-speed stirring, when dealing with high-viscosity sludge, the stirring process will cause the problem of temperature rise and the energy consumption is high.

[0033] Example 2, Reference Figure 7-8 The difference between this embodiment and embodiment 1 is that a return plate 6 is installed at an angle on the side of the compost bed 1 near the frame 2, and a screen hole is opened on the return plate 6. A conveying box 5 is set near the top of the return plate 6. The water outlet pipe of the water pump 3 is connected to the conveying box 5. A corresponding water outlet hole is set at the bottom of the conveying box 5. A bracket 17 is symmetrically arranged at the bottom of the return plate 6. A receiving plate 18 is inserted between two brackets 17. Multiple grids 22 are set on the inner side of the receiving plate 18. A water outlet hole is also set on the receiving plate 18. The middle position of the grid 22 is inclined towards the water flow direction. A slot 23 is opened in the middle of the grid 22. Activated carbon particles 24 are filled inside the slot 23.

[0034] When silt separates into layers, the water separated from the upper layer contains a large amount of colloids, which need to be treated during the water extraction process.

[0035] To this end, the outlet pipe of the water pump 3 is connected to the inside of the conveying box 5. Water falls from the bottom of the conveying box 5 to avoid splashing caused by the water coming out of the outlet pipe directly contacting the return plate 6. After the water comes out from the bottom of the conveying box 5 and falls onto the return plate 6, it will fall through the holes on the return plate 6. The two sides of the bottom of the return plate 6 are effectively fixed by two symmetrically arranged L-shaped brackets 17. After the receiving plate 18 catches the water falling from the return plate 6, the water will pass through multiple grids 22 in sequence. The slots 23 in the middle of the grids 22 are filled with activated carbon particles 24. The activated carbon particles 24 adsorb the colloid. The water that passes through is discharged from the outlet hole at the bottom of the receiving plate 18 for subsequent treatment.

[0036] Example 3, Reference Figure 5-6 The difference between this embodiment and Embodiment 1 and Embodiment 2 is that one side of the actuating plate 16 is sloping and a platform is provided at the top of the slope. A receiving cavity 21 is provided on the inner side of the actuating plate 16. An adjustment structure 20 is provided at the platform position at the top of the receiving cavity 21. The adjustment structure 20 includes a float plate 201, a conical groove 202, a conical plate 203, a straight plate 204, and a grid strip 205. Straight plates 204 are symmetrically arranged on the top of the receiving cavity 21. Grid strips 205 are arranged in an array between the lower ends of the two straight plates 204. A conical groove 202 is opened through the platform on the actuating plate 16. Conical plates 203 are placed on the grid strips 205. Multiple floating plates 201 are arranged on the upper part of the conical plates 203. When the position of the floating plates 201 rises, the upper end of the floating plates 201 passes through the conical groove 202 and extends to the outside. Aeration components 12 are arranged in a rectangular array at the bottom of the compost bed 1, and the actuating plate 16 is located above the aeration components 12.

[0037] After the silt in the mining area settles and stratifies, a transition layer will form at the interface between the liquid and the silt. If the transition layer is not treated in time, it will gradually become dense, which will increase the difficulty of subsequent treatment. At the same time, due to the high viscosity of the silt, some suspended particles will be trapped in the silt and will be difficult to float and collect.

[0038] Therefore, slopes are provided on both sides of the agitator 16, and a platform is provided at the upper end of the slope. The position of the agitator 16 is readjusted so that the bottom of the agitator 16 extends into the silt by 1-3 cm. During the movement of the agitator 16, the silt on the surface is lifted up, and the surface transition layer reaches the platform position at the upper end of the slope along the slope of the agitator 16. An adjustment component 20 is provided at the platform position. The adjustment component 20 includes a float 201, a conical groove 202, a conical plate 203, a straight plate 204, and a grid strip 205. When the water in the upper layer of sludge is not drained, the water submerges the agitator 16, causing the floats 201 inside the conical groove 202 to move upward under buoyancy. At this time, multiple floats 201 will lift the lower conical plates 203 upward until the conical plates 203 are stuck inside the conical groove 202, thus sealing the conical groove 202. When the agitator 16 first enters the water, the floats 201 do not float, and a small amount of water enters the receiving cavity 21. The amount of water entering is small and negligible. When the water in the upper layer is drained, the floats 201 fall. During the movement of the agitator 16, the material of the transition layer is continuously introduced into the inner side of the receiving cavity 21 through the gap between the conical groove 202 and the baffle strip 205. During this process, the microbubbles emitted by the aeration components 12 at the bottom of the compost bed 1 can combine with the suspended particles in the sludge, increasing their buoyancy and successfully floating to the transition layer area for collection.

[0039] The working principle of this device is as follows: The sludge collected underground was injected into compost bed 1. After a period of settling, the sludge was separated into layers, with the lower layer being sludge and the upper layer being water. Because the sludge in the mine contained montmorillonite, the sludge was very sticky, which was not conducive to the subsequent treatment of the sludge.

[0040] To this end, a frame 2 is installed on one side of the compost bed 1, and a stepper motor 7 is installed on one side of the frame 2. When the stepper motor 7 is powered on, it drives the threaded rod 4 in the middle to rotate. A threaded sleeve 8 is installed on the outside of the threaded rod 4, and the threaded sleeve 8 and the top of the frame 2 are provided with guide grooves for limiting the movement of the threaded sleeve 8 along the axial direction of the threaded rod 4. At the same time, it is fixed to one side of the threaded sleeve 8 by a connecting plate 9, and the connecting plate 9 is connected to a cone at the lower end by an electric telescopic rod 10. The conical barrel 11 is wider at the top and narrower at the bottom. The position and height of the conical barrel 11 are adjusted by the electric telescopic rod 10, so that the lower half of the conical barrel 11 extends into the upper layer of sludge. The water pump 3 is started, and the water pump 3 draws water out of the compost bed 1. During this process, the position of the conical barrel 11 can be linearly moved through the threaded sleeve 8, constantly changing its position and adjusting the water pumping control. At the same time, the bottom of the conical barrel 11 is compositely bonded with a filter cloth 25 to ensure that the sludge is not drawn out during the water pumping process.

[0041] To further address the viscosity of the sludge, a container 26 is installed on one side of the conical bucket 11. Fly ash slurry is added to the inside of the container 26. If fly ash is added directly to the viscous sludge, it will cause the fly ash to float and agglomerate, forming localized enrichment areas. Therefore, the fly ash slurry needs to be mixed in the container 26 beforehand. When the agitator 16 extends into the sludge, the electric valve on the conveying pipe 13 between the container 26 and the agitator 16 is activated. After the valve is activated, the fly ash slurry flows from the channel 1... 9 leaks out and directly enters the bottom of the sludge. At the same time, since the agitator plate 16 is connected to the side wall of the conical barrel 11, the agitator plate 16 moves in the sludge as the conical barrel 11 moves. On the one hand, it can fully and evenly inject the fly ash slurry into all parts of the sludge. On the other hand, the agitator plate 16 can slowly contact the sludge during its movement, thus achieving a stirring effect. Compared with traditional high-speed stirring, when dealing with high-viscosity sludge, the stirring process will cause the problem of temperature rise and the energy consumption is high.

[0042] When silt separates into layers, the water separated from the upper layer contains a large amount of colloids, which need to be treated during the water extraction process.

[0043] To this end, the outlet pipe of the water pump 3 is connected to the inside of the conveying box 5. Water falls from the bottom of the conveying box 5 to avoid splashing caused by the water coming out of the outlet pipe directly contacting the return plate 6. After the water comes out from the bottom of the conveying box 5 and falls onto the return plate 6, it will fall through the holes on the return plate 6. The two sides of the bottom of the return plate 6 are effectively fixed by two symmetrically arranged L-shaped brackets 17. After the receiving plate 18 catches the water falling from the return plate 6, the water will pass through multiple grids 22 in sequence. The slots 23 in the middle of the grids 22 are filled with activated carbon particles 24. The activated carbon particles 24 adsorb the colloid. The water that passes through is discharged from the outlet hole at the bottom of the receiving plate 18 for subsequent treatment.

[0044] After the silt in the mining area settles and stratifies, a transition layer will form at the interface between the liquid and the silt. If the transition layer is not treated in time, it will gradually become dense, which will increase the difficulty of subsequent treatment. At the same time, due to the high viscosity of the silt, some suspended particles will be trapped in the silt and will be difficult to float and collect.

[0045] Therefore, slopes are provided on both sides of the agitator 16, and a platform is provided at the upper end of the slope. The position of the agitator 16 is readjusted so that the bottom of the agitator 16 extends into the silt by 1-3 cm. During the movement of the agitator 16, the silt on the surface is lifted up, and the surface transition layer reaches the platform position at the upper end of the slope along the slope of the agitator 16. An adjustment component 20 is provided at the platform position. The adjustment component 20 includes a float 201, a conical groove 202, a conical plate 203, a straight plate 204, and a grid strip 205. When the water in the upper layer of sludge is not drained, the water submerges the agitator 16, causing the floats 201 inside the conical groove 202 to move upward under buoyancy. At this time, multiple floats 201 will lift the lower conical plates 203 upward until the conical plates 203 are stuck inside the conical groove 202, thus sealing the conical groove 202. When the agitator 16 first enters the water, the floats 201 do not float, and a small amount of water enters the receiving cavity 21. The amount of water entering is small and negligible. When the water in the upper layer is drained, the floats 201 fall. During the movement of the agitator 16, the material of the transition layer is continuously introduced into the inner side of the receiving cavity 21 through the gap between the conical groove 202 and the baffle strip 205. During this process, the microbubbles emitted by the aeration components 12 at the bottom of the compost bed 1 can combine with the suspended particles in the sludge, increasing their buoyancy and successfully floating to the transition layer area for collection.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
