Description

Technical Field

[0001] The utility model belongs to the technical field of wastewater treatment, and particularly relates to a high-efficiency separation and treatment system for muddy sand wastewater. Background Art

[0002] Mine wastewater contains different mud, sand, mineral impurities, etc. The characteristic of sand washing wastewater is high sediment content. During the sand washing process, the soil mixed with sand and stones is extremely easy to turn into mud and suspend in the sand washing wastewater to form slurry. The most important thing in treating sand washing wastewater is to separate mud and water, reduce the suspended solids in the water, and transport the treated waste mud and slag out for disposal.

[0003] The utility model patent with domestic application number 202221143383.4 discloses a new type of sand washing wastewater treatment system, including a sand washing recovery device, a tail water tank, a coagulation tank, a high-efficiency deep cone thickener, a clear water tank and a filter press. The sand washing recovery device and the tail water tank are connected through a pipeline. The tail water tank and the coagulation tank are connected through a sewage pump. The coagulation tank is connected to one side of the top of the high-efficiency deep cone thickener. The clear water tank is connected to one side of the high-efficiency deep cone thickener. A steady flow cylinder is arranged inside the high-efficiency deep cone thickener. The rotating shaft penetrates through the middle position of the steady flow cylinder. A discharge hopper is arranged at the bottom of the high-efficiency deep cone thickener. An outlet is arranged at the bottom of the high-efficiency deep cone thickener. The conical discharge hopper facilitates the solid-liquid separation of the ore mud in the tank. The ore mud deposited at the bottom of the tank is continuously scraped into the discharge hopper by a scraper and discharged through a sludge discharge pipe. The clarified water is discharged into the clear water tank through an overflow trough on one side of the top of the tank, improving the treatment effect of sand washing wastewater. The above utility model uses a conical discharge hopper to separate solid and liquid from wastewater, and a scraper is used to scrape the ore mud. However, the ore mud itself has a certain adsorption effect, and both the ore mud and sand and stones have a certain weight. Only by settling to treat them, it is impossible to ensure that there is no sand and stone residue in the ore mud, reducing the completeness of sand and stone filtration in wastewater treatment, reducing the recovery amount of sand and stones, and reducing the environmental protection effect of secondary utilization of sand and stones. Content of the Utility Model

[0004] In order to solve the above technical problems, the utility model provides a high-efficiency separation and treatment system for muddy sand wastewater, including a bottom plate, a sedimentation tank fixedly installed on the top of the bottom plate, a stirring tank installed on the top of the sedimentation tank, a driving motor fixedly installed on the top of the stirring tank, a secondary filter tank fixedly installed on the top of the bottom plate on one side of the sedimentation tank, a main shaft motor fixedly installed on the secondary filter tank, and a conveying pump and a circulation pump fixedly installed on the top of the bottom plate for conveying. A stirring paddle is rotatably installed inside the stirring tank through the driving of the driving motor. A screening box is installed between the sedimentation tank and the stirring tank.

[0005] The stirring paddle is rotated by a driving motor to stir the wastewater inside the stirring tank, so that the dust, soil and sand in the sediment are suspended inside the stirring tank, and preliminary sedimentation is carried out through a screening box at the bottom of the stirring tank to achieve the filtering effect of the sand and gravel, and then it enters the sedimentation tank for sedimentation. The circulating pump circulates and conveys the wastewater inside the sedimentation tank, so that it is stirred and suspended inside the stirring tank for multiple times. After multiple circulating conveying operations, the conveying pump conveys the wastewater inside the sedimentation tank to the secondary filter tank for secondary sand washing.

Three support columns are fixedly installed around the outside of the sedimentation tank.

[0007] The feeding port formed between the inclined feeding plates can achieve the filtering effect on the wastewater, so that larger-diameter sand and gravel or other garbage are stuck at the position of the feeding port, which is convenient for subsequent cleaning.

[0008] As a further preferred technical solution of the present utility model; the output end of the driving motor penetrates through the outer shell of the stirring tank and is fixedly installed with the stirring paddle. A feeding port is provided on one side of the top of the stirring tank, and a discharging port is provided at the bottom of the stirring tank. A connecting rod is installed at the bottom of the stirring paddle at the position of the discharging port through thread docking. A round-hole filter plate is fixedly installed at the bottom of the connecting rod, and a plurality of inclined filter plates are fixedly installed between the top of the round-hole filter plate and the connecting rod.

[0009] Due to the inclined setting of the inclined filter plates, it is convenient for the inclined filter plates to attach and filter dust or sand and gravel. During the process of the driving motor driving the stirring paddle to rotate, the inclined filter plates cooperate with the round-hole filter plate to rotate inside the screening box, delaying the water outlet speed of the wastewater at the bottom of the stirring tank, thereby ensuring the completeness of filtration. After the filtration is completed, the screening box can be removed, and the connecting rod can be removed, so as to collect part of the sand and gravel.

[0010] As a further preferred technical solution of the present utility model; the secondary filter tank includes a cover plate placed on the top and an installation pipe welded and installed integrally. The bottom of the secondary filter tank is fixedly installed with the bottom plate through a support seat. A spiral lifting rod is installed inside the installation pipe. The output end of the main shaft motor penetrates through the installation pipe and is rotatably installed with the spiral lifting rod, and the other end of the spiral lifting rod is fixedly installed with the side wall of the installation pipe through a rotating bearing. A drainage plate is fixedly installed at the bottom of one end of the installation pipe, and a sand outlet is provided at the bottom of the drainage plate.

[0011] The sediment inside the secondary filter tank is lifted by the rotation of the spiral lifting rod. During the lifting process, the muddy water flows back into the secondary filter tank through the gap between the spiral lifting rod and the side wall of the installation pipe, thereby performing secondary collection of the sand and gravel to ensure the completeness of the sand and gravel collection. Moreover, during the rotation of the spiral lifting rod, the waste water at the bottom of the secondary filter tank will be rotated, achieving a stirring effect, separating the sand and gravel in the muddy water from the muddy water, which is beneficial to the collection of the sand and gravel.

[0012] As a further preferred technical solution of the present utility model; the screening box and the bottom of the stirring tank are fixedly installed through a mounting plate and mounting bolts, the bottom of the stirring tank and the top of the sedimentation tank are connected and installed through a lifting column, and a semi-circular filter screen plate is arranged at the bottom of the screening box.

[0013] By lifting and lowering the lifting column, the screening box is removed, thereby collecting the sand and gravel filtered at the bottom of the screening box and the connecting rod.

[0014] As a further preferred technical solution of the present utility model; the delivery pump is respectively connected and installed with the sedimentation tank and the secondary filter tank through a suction pipe and a delivery pipe, and the circulation pump is respectively docked and installed with the sedimentation tank and the stirring tank through a circulation pipe and a connecting pipe. Solenoid valves are installed on both the delivery pipe and the connecting pipe.

[0015] The water inside the sedimentation tank is circulated and transported to the inside of the stirring tank for stirring and filtering by the circulation pump, improving the completeness of the waste water treatment; the secondary-treated waste water is then extracted from the inside of the sedimentation tank by the delivery pump and transported to the inside of the secondary filter tank, thereby ensuring the delivery effect of the waste water.

[0016] Beneficial effects

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0018] 1. The waste water inside the sedimentation tank is circulated and transported by the circulation pump, so that it is stirred and suspended inside the stirring tank multiple times. Since the density of the soil is less than that of the sand and gravel, repeated operations can ensure the completeness of the separation of the sand and gravel from the soil, and the waste water is filtered multiple times by the screening box to achieve multiple filtration effects of the waste water. In cooperation with the rotation of the spiral lifting rod to lift the sediment inside the secondary filter tank, during the lifting process, the muddy water flows back into the secondary filter tank through the gap between the spiral lifting rod and the side wall of the installation pipe, thereby performing secondary collection of the sand and gravel to ensure the completeness of the sand and gravel collection. Moreover, during the rotation of the spiral lifting rod, the waste water at the bottom of the secondary filter tank will be rotated, achieving a stirring effect, separating the sand and gravel in the muddy water from the muddy water, which is beneficial to the collection of the sand and gravel.

[0019] 2. Through the inclined setting of the inclined filter plate, it is convenient for the inclined filter plate to attach and filter dust or sand and gravel. During the rotation of the stirring paddle driven by the drive motor, the rotation of the inclined filter plate and the round hole filter plate inside the screening box delays the water outlet speed of the wastewater at the bottom of the stirring tank, thus ensuring the completeness of filtration. After the filtration is completed, the connecting rod can be removed by removing the screening box, so as to collect some sand and gravel. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] This specific embodiment is a high-efficiency separation and treatment system for mud and sand wastewater.

However, the ore mud itself has a certain adsorption effect, and both the ore mud and sand and gravel have a certain weight. Only by sedimentation to treat it, during the sedimentation process, the sand and gravel will be mixed with the soil again, unable to reduce the sand and gravel residue in the ore mud, reduce the completeness of sand and gravel filtration in wastewater treatment, reduce the recovery amount of sand and gravel, and reduce the environmental protection effect of secondary utilization of sand and gravel.

[0028] Its structural schematic diagram is asFigures 1 - 3 As shown in the figure. A high-efficiency separation and treatment system for sediment-laden wastewater includes a bottom plate 1 and a sedimentation tank 3 fixedly installed on the top of the bottom plate 1. The top of the sedimentation tank 3 is provided with a water outlet 35, and a plurality of inclined blanking plates 33 are fixedly installed inside the sedimentation tank 3. A blanking port 34 is formed between the inclined blanking plates 33. Three support columns 32 are fixedly installed around the outside of the sedimentation tank 3. The blanking port 34 formed between the inclined blanking plates 33 can achieve the effect of filtering wastewater, so that larger-diameter sand or other garbage is stuck at the position of the blanking port 34, which is convenient for subsequent cleaning.

[0029] It includes a stirring tank 4 installed on the top of the sedimentation tank 3.

A connecting rod 45 is installed at the bottom of the stirring paddle 41 at the position of the discharging port 46 through thread docking. A round hole filter plate 48 is fixedly installed at the bottom of the connecting rod 45, and a plurality of inclined filter plates 47 are fixedly installed between the top of the round hole filter plate 48 and the connecting rod 45. Due to the inclined setting of the inclined filter plates 47, it is convenient for the inclined filter plates 47 to attach and filter dust or sand. During the process of the driving motor 5 driving the stirring paddle 41 to rotate, the inclined filter plates 47 cooperate with the round hole filter plate 48 to rotate inside the screening box 31, delaying the water outlet speed of the wastewater at the bottom of the stirring tank 4, thereby ensuring the completeness of filtration. After the filtration is completed, by removing the screening box 31, the connecting rod 45 can be removed, so as to collect some sand and gravel.

[0030] The structural schematic diagram is as Figures 4 - 5 shown in the figure. It includes a driving motor 5 fixedly installed on the top of the stirring tank 4 and a secondary filter tank 6 fixedly installed on the top of the bottom plate 1 on one side of the sedimentation tank 3. The secondary filter tank 6 includes a cover plate 62 placed on the top and a mounting pipe 61 welded and installed integrally. The bottom of the secondary filter tank 6 is fixedly installed with the bottom plate 1 through a support seat 66. A spiral lifting rod 65 is installed inside the mounting pipe 61. The output end of the main shaft motor 7 penetrates through the mounting pipe 61 and is rotatably installed with the spiral lifting rod 65, and the other end of the spiral lifting rod 65 is fixedly installed with the side wall of the mounting pipe 61 through a rotating bearing. One end of the bottom of the mounting pipe 61 is fixedly installed with a drainage plate 63, and a sand outlet 64 is opened at the bottom of the drainage plate 63. By rotating the spiral lifting rod 65, the sediment inside the secondary filter tank 6 is lifted. During the lifting process, the muddy water flows back into the secondary filter tank 6 through the gap between the spiral lifting rod 65 and the side wall of the mounting pipe 61, thereby collecting the sand and gravel for the second time and ensuring the completeness of the sand and gravel collection. And when the spiral lifting rod 65 rotates, it will cause the wastewater at the bottom of the secondary filter tank 6 to rotate, achieving a stirring effect, separating the sand and gravel in the muddy water from the muddy water, which is beneficial to the collection of sand and gravel.

[0031] It also includes a main shaft motor 7 fixedly installed on the secondary filter tank 6, a delivery pump 2 fixedly installed on the top of the bottom plate 1 for conveying, and a circulation pump 24. Inside the mixing tank 4, a mixing paddle 41 is rotatably installed by driving of a driving motor 5, and a screening box 31 is installed between the sedimentation tank 3 and the mixing tank 4. The screening box 31 and the bottom of the mixing tank 4 are fixedly installed through a mounting plate 311 and mounting bolts 49. The bottom of the mixing tank 4 and the top of the sedimentation tank 3 are connected and installed through a lifting column 43. The bottom of the screening box 31 is provided with a semi-circular filter plate 312. By lifting the lifting column 43, the screening box 31 is removed, so as to collect the sand and gravel filtered at the bottom of the screening box 31 and the connecting rod 45.

[0032] The delivery pump 2 is respectively connected and installed with the sedimentation tank 3 and the secondary filter tank 6 through a suction pipe 23 and a delivery pipe 22, and the circulation pump 24 is respectively docked and installed with the sedimentation tank 3 and the mixing tank 4 through a circulation pipe 36 and a connecting pipe 44.

The water inside the sedimentation tank 3 is circulated and conveyed to the inside of the mixing tank 4 by the circulation pump 24 for stirring and filtering, which improves the completeness of the wastewater treatment; the secondary-treated wastewater is pumped into the sedimentation tank 3 by the delivery pump 2 and then conveyed to the inside of the secondary filter tank 6, so as to ensure the conveying effect of the wastewater.

[0033] The driving motor 5 drives the mixing paddle 41 to rotate to stir the wastewater inside the mixing tank 4, so that the dust, soil and sand in the mud and sand are suspended inside the mixing tank 4, and are preliminarily settled by the screening box 31 at the bottom of the mixing tank 4 to achieve the filtering effect of the sand and gravel, and then enter the sedimentation tank 3 for sedimentation. The circulation pump 24 circulates and conveys the wastewater inside the sedimentation tank 3, so that it is stirred and suspended inside the mixing tank 4 for many times. Since the density of the soil is less than that of the sand and gravel, repeated operations can ensure the completeness of the separation of the sand and gravel from the soil, and the screening box 31 filters many times to achieve the effect of filtering the wastewater many times. After many times of circulating and conveying operations, the delivery pump 2 conveys the wastewater inside the sedimentation tank 3 to the secondary filter tank 6 for secondary sand washing. The main shaft motor 7 drives the spiral lifting rod 65 to rotate. The rotation of the spiral lifting rod 65 itself has a certain stirring effect, which can suspend the sand and gravel again. During the conveying process of the spiral lifting rod 65, the muddy water flows back into the secondary filter tank 6 from the inner wall of the installation pipe 61, so as to ensure the completeness of the separation between the sand and gravel and the soil and reduce the situation of sand and gravel remaining in the soil. Finally, the wastewater is conveyed through another group of pipes on the secondary filter tank 6, and the cleanliness treatment of the wastewater improves the overall treatment effect of the wastewater treatment system.
