Description

Technical Field

[0001] The present invention relates to the technical field of underground mining, and more specifically, to a muddy water treatment device for underground mining. Background Art

[0002] At present, most underground metal mines adopt the backfilling method for mining, and some mines use tailings after beneficiation as backfill aggregate to backfill the goaf. Generally, these tailings will be sealed in the goaf during backfilling, but due to some uncontrollable factors in the production process, these tailings will overflow and form muddy water, which will have a certain impact on the environment. Muddy water treatment equipment is needed to separate the muddy water into solid and liquid; However, the existing underground mining mud water treatment equipment has the following shortcomings when performing solid-liquid separation on mud water: the mud water is separated into solid and liquid by sedimentation and filtration, and the separated liquid is located on the upper layer of the soil. The height of the layer between the separated liquid and the soil is different each time, making it difficult to fully extract the liquid. Moreover, although the soil is settled below, the moisture content of the soil after separation is still very high, reducing the effect of solid-liquid separation of mud water. Summary of the invention

[0003] The technical solution adopted by the present invention to achieve the technical purpose is: an underground mining mud and water treatment device, whose structure includes a treatment box, a feed port, supporting legs, an extraction mechanism, a water storage tank, and a rolling box. The mud and water are discharged from the feed port into the treatment box for sedimentation. Four supporting legs are supported at the bottom of the treatment box. The extraction mechanism extracts the liquid inside the treatment box into the water storage tank. The mud after solid-liquid separation inside the treatment box is discharged into the rolling box. A scraper is provided inside the treatment box, and a motor is provided at the lower left end of the treatment box. A driving block is provided at the bottom of the scraper. A connecting seat is provided at the lower end of the driving block and is connected to a slider provided at the lower end of the scraper. A driving rod provided at the front end of the motor drives the worm provided at the lower end of the scraper to rotate, and the worm drives the slider to slide inside a protective tube provided at the bottom inner side of the treatment box. The protective tube is a long strip structure, and the top is an arc-shaped surface structure, which can protect the internal slider and worm.

[0004] As a further improvement of the present invention, a side scraper is provided on the side of the scraper, which scrapes the soil on the side of the inside of the processing box, and a lower guide plate is provided at the front end of the scraper, through which the soil at the front end of the scraper flows downwardly.

[0005] As a further improvement of the present invention, the extraction mechanism consists of a liquid pump, a drainage pipe, a telescopic hose, a float and a sinking pipe. The liquid pump is installed on the top of the water tank, and the liquid pump is connected to the telescopic hose through the connected drainage pipe. The telescopic hose, the float and the sinking pipe are all located inside the treatment box. There are two floats and they are installed on both sides of the middle part of the sinking pipe. Under the buoyancy of the float, the sinking pipe can rise and fall and float following the height of the surface of the separated liquid.

[0006] As a further improvement of the present invention, a mud inlet, a filter bag, a rolling mechanism, a mud outlet and a liquid collecting tank are provided inside the rolling box. The mud inlet and the mud outlet are respectively arranged at the upper left corner and the lower right corner of the rolling box, and the head and tail ends of the filter bag are installed between the mud inlet and the mud outlet. The rolling mechanism is against the inclined surface of the filter bag. The liquid collecting tank is located below the filter bag. The lower inclined surface of the filter bag is supported by a supporting filter plate arranged on the top of the liquid collecting tank. The filter bag is arranged in an inclined state inside the rolling box, so that the mud can be smoothly discharged from the mud inlet into the filter bag for dehydration.

[0007] As a further improvement of the present invention, a cylinder is provided on the rolling mechanism, and a push rod is provided at the lower end of the cylinder. When the cylinder is running, the push rod pushes the pressure plate provided on the rolling mechanism to squeeze the inclined surface of the filter bag.

[0008] As a further improvement of the present invention, a side connecting rod is further provided above the push rod, the lower end of the side connecting rod is arranged at the upper end of the edge of the pressure plate, and a pressure wheel is further provided inside the edges at both ends of the pressure plate, the pressure wheel abuts against the edge end of the inclined surface on the filter bag, and the side connecting rod is provided with two, and is arranged on both sides of the push rod and at both ends of the edge of the pressure plate, to provide support force for the cylinder to push the pressure plate to squeeze the filter bag as a whole, thereby ensuring that the pressure plate can effectively squeeze the filter bag as a whole.

[0009] The beneficial effects of the present invention are: 1. During the pumping process, the liquid height continues to drop. Under the action of the float and the telescopic hose, the sinking pipe can always remain inside the upper surface of the liquid, so that all the precipitated and separated liquid is pumped into the water tank, improving the effect of solid-liquid separation; 2. The starting cylinder, connected with the push rod, causes the pressure plate to squeeze the top of the filter bag. At the same time, the two pressure wheels at the two ends of the pressure plate press the connection between the filter bag and the mud inlet and outlet to prevent the mud inside the filter bag from being squeezed out from the mud inlet and outlet when the pressure plate squeezes and dehydrates the mud. The mud inside the filter bag is then crushed and dehydrated, reducing the moisture content of the mud, thereby improving the effect of solid-liquid separation of mud and water.

DETAILED DESCRIPTION

[0017] The present invention is further described below in conjunction with the accompanying drawings: Example

[0018] As attached Figure 1 To Attachment Figure 4 As shown: The present invention discloses an underground mining mud water treatment device, which structure includes a treatment box 1, a feed port 2, a support leg 3, an extraction mechanism 4, a water storage tank 5, and a rolling box 6. Mud water is discharged from the feed port 2 into the treatment box 1 for sedimentation. Four support legs 3 are supported at the bottom of the treatment box 1. The extraction mechanism 4 extracts the liquid inside the treatment box 1 into the water storage tank 5. The mud after solid-liquid separation inside the treatment box 1 is discharged into the rolling box 6. A scraper 11 is provided inside the treatment box 1, and a motor 12 is provided at the lower left end of the treatment box 1. A driving block 111 is provided at the bottom of the scraper 11. A connecting seat 112 is provided at the lower end of the driving block 111 to connect with a slider 113 provided at the lower end of the scraper 11. The front end of the motor 12 is provided with a The driving rod 121 drives the worm 114 set at the lower end of the scraper 11 to rotate, and the worm 114 drives the slider 113 to slide inside the protective tube 115 set at the bottom of the inner side of the processing box 1. The side of the scraper 11 is provided with a side scraper 116, and the side scraper 116 scrapes the soil on the side of the processing box 1. The front end of the scraper 11 is provided with a lower guide plate 117, and the soil at the front end of the scraper 11 is tilted downward by the lower guide plate 117. The extraction mechanism 4 consists of a liquid pump 41, a drainage pipe 42, a telescopic hose 43, a float 44 and a sinking pipe 45. The liquid pump 41 is installed on the top of the water storage tank 5, and the liquid pump 41 is connected to the telescopic hose 43 through the connected drainage pipe 42. The hose 43, the float 44 and the sinking pipe 45 are all located inside the treatment box 1. In the present invention, the muddy water generated by ore washing is discharged from the feed port 2 into the treatment box 1 for solid-liquid sedimentation separation. The liquid after sedimentation separation is in the upper layer of the mud. According to the height of the separated liquid inside the treatment box 1, the lower end of the sinking pipe 45 is driven to sink inside the upper surface layer of the liquid under the buoyancy of the float 44. The liquid pump 41 is started to pump the separated liquid from the sinking pipe 45 into the water storage tank 5 through the discharge pipe 42 and the telescopic hose 43. During the pumping process, the liquid height continues to decrease. Under the action of the float 44 and the telescopic hose 43, it is ensured that the sinking pipe 45 can always remain inside the upper surface layer of the liquid, thereby separating the sediment. All the liquid is pumped into the water tank 5 to improve the solid-liquid separation effect. After the liquid is extracted, the motor 12 is started to rotate the worm 114 driven by the driving rod 121, and the driving slider 113 slides on the worm 114. Under the connection of the connecting seat 112, the driving block 111 drives the scraper 11 to move in the direction of the rolling box 6 inside the processing box 1, and the precipitated and separated mud is scraped into the rolling box 6. The side scraper 116 is used to scrape the mud on the side of the processing box 1, and the lower guide plate 117 is used to tilt the mud at the front end of the scraper 11 downward to ensure that all the precipitated and separated mud can be scraped into the rolling box 6 for dehydration again, thereby improving the solid-liquid separation effect of mud and water.

[0019] A preferred technical solution, the protection tube 115 is a long strip structure, and the top is an arc-shaped surface structure, which can protect the internal slider 113 and the worm 114, and prevent the precipitated mud from adhering to the surface of the worm 114, so that the worm 114 cannot smoothly drive the slider 113 to drive the scraper 11 to slide, and the scraper 11 is used to scrape the mud settled at the bottom of the processing box 1 toward the rolling box 6, and the precipitated mud is dehydrated again; A better technical solution is that there are two floats 44 and they are installed on both sides of the middle part of the sinking tube 45. Under the buoyancy of the float 44, the sinking tube 45 can rise and fall with the height of the surface of the separated liquid. The lower end of the sinking tube 45 sinks into the liquid to extract the precipitated and separated liquid, ensuring that the separated liquid can be fully extracted. Embodiment 2: Based on embodiment 1, as shown in the attached Figure 5 To Attachment Figure 6 As shown: As a further improvement of the present invention, the rolling box 6 is provided with a mud inlet 61, a filter bag 62, a rolling mechanism 63, a mud outlet 64 and a liquid collecting tank 65. The mud inlet 61 and the mud outlet 64 are respectively arranged at the upper left corner and the lower right corner of the rolling box 6, and the head and tail ends of the filter bag 62 are installed between the mud inlet 61 and the mud outlet 64. The rolling mechanism 63 is against the inclined surface of the filter bag 62. The liquid collecting tank 65 is located below the filter bag 62. The support filter plate 651 arranged at the top supports the lower inclined surface of the filter bag 62. The rolling mechanism 63 is provided with a cylinder 631, and a push rod 632 is provided at the lower end of the cylinder 631. When the cylinder 631 is running, the push rod 632 pushes the pressing plate 633 arranged on the rolling mechanism 63 to squeeze the upper inclined surface of the filter bag 62. A side connecting rod 634 is also provided above the push rod 632. The lower end of the side connecting rod 634 is arranged at the upper end of the edge of the pressing plate 633, and the pressing plate 633 is provided at the bottom of the pressing plate 633. The edges of both ends of the filter bag 62 are also provided with pressure wheels 635, and the pressure wheels 635 are abutted against the edge ends of the inclined surfaces of the filter bag 62. In the present invention, when the mud is discharged into the rolling box 6, it is obliquely discharged into the filter bag 62 from the mud inlet 61. When all the mud is concentrated in the filter bag 62, the cylinder 631 is started to squeeze the pressure plate 633 on the top of the filter bag 62 under the connection of the push rod 632. At the same time, the two pressure wheels 635 on the edges of both ends of the pressure plate 633 press the connection between the filter bag 62 and the mud inlet 61 and the mud outlet 64, so as to prevent the pressure plate 633 from squeezing and dehydrating the mud inside the filter bag 62 from squeezing and dehydrating the mud from the mud inlet 61 and the mud outlet 64, thereby rolling and dehydrating the mud inside the filter bag 62, reducing the moisture content of the mud, thereby improving the effect of solid-liquid separation of mud and water, and the liquid discharged flows into the liquid collecting tank 65 through the supporting filter plate 651 for centralized collection, and finally the dehydrated mud is discharged from the mud outlet 64.

[0020] A preferred technical solution is that the filter bag 62 is arranged in an inclined state inside the rolling box 6, so that the mud can be smoothly discharged from the mud inlet 61 into the filter bag 62 for dehydration, and the filter bag 62 is prevented from falling under the support of the filter plate 651, and the liquid that escapes from the filter bag 62 can be discharged into the liquid collecting tank 65; A preferred technical solution, there are two side connecting rods 634, and they are arranged on both sides of the push rod 632 and at both ends of the edge of the pressure plate 633, to provide support for the cylinder 631 to push the pressure plate 633 to squeeze the filter bag 62 as a whole, to ensure that the pressure plate 633 can effectively squeeze the filter bag 62 as a whole, and to press the connection between the filter bag 62 and the mud inlet 61 and the mud outlet 64 through two pressure wheels 635, to prevent the pressure plate 633 from squeezing and dehydrating the mud inside the filter bag 62 from squeezing out the mud from the mud inlet 61 and the mud outlet 64, to ensure that the mud is efficiently dehydrated inside the filter bag 62, and to improve the effect of solid-liquid separation of mud and water. Utilizing the technical solution of the present invention, or those skilled in the art designing similar technical solutions inspired by the technical solution of the present invention to achieve the above-mentioned technical effects, all fall within the protection scope of the present invention.
