Description

Technical Field

[0001] This utility model relates to the field of tailings treatment technology, specifically to a tailings treatment solid-liquid separation device. Background Technology

[0002] Solid-liquid separation is a crucial step in tailings treatment. Chinese Patent No. CN219489820U discloses a solid-liquid separation device for tailings and sludge treatment, comprising a separation shell. The device is characterized in that: a shock-absorbing support leg is detachably installed at the lower end of the separation shell, and a conveying mechanism is detachably installed inside the separation shell. The shock-absorbing support leg includes a mounting plate detachably installed at the lower end of the separation shell, and a sliding column is fixedly installed at the lower end of the mounting plate, with a spring shock absorber provided on the sliding column.

[0003] The above-mentioned device can perform solid-liquid separation of tailings during the transportation process. However, in actual operation, when the screw conveyor rotates too fast, the water in the tailings cannot be discharged from the liquid outlet in time, resulting in poor solid-liquid separation effect. Moreover, under long-term operation, the liquid outlet in the above-mentioned prior art is prone to blockage, affecting the separation effect and normal operation of the equipment, and is inconvenient to use. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a tailings solid-liquid separation device that solves the problem of poor separation performance in existing devices.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tailings treatment solid-liquid separation device, comprising a shell, an inlet at the top of the shell, an inclined screen plate inside the shell, a partition plate fixedly connected to the lower end of the screen plate, the partition plate fixedly disposed at the bottom of the shell and dividing the bottom of the shell into a drainage chamber and a sludge discharge chamber, an open structure on the upper side of the shell, a cleaning assembly connected to the shell above the screen plate, a horizontal plate inside the drainage chamber, a conical opening on the horizontal plate, a filter screen at the bottom of the conical opening, and a conveying assembly inside the sludge discharge chamber.

[0006] Preferably, the cleaning assembly includes a pair of electric slide rails disposed on the outer walls of both sides of the housing, the inclination of the electric slide rails being the same as the inclination of the sieve plate, a pair of electric sliders disposed on the pair of electric slide rails, a movable frame installed between the pair of electric sliders, a screw screwed onto the movable frame, an adjusting frame rotatably mounted on the lower end of the screw, a cleaning roller rotatably mounted inside the adjusting frame, a cleaning brush disposed on the outer wall of the cleaning roller, a pair of guide rods fixedly disposed on the adjusting frame, and a guide hole for the guide rods to pass through the movable frame.

[0007] Preferably, the conveying assembly includes a rotating shaft rotatably installed in the sludge discharge chamber, a conveying auger is provided on the rotating shaft, and a motor connected to one end of the rotating shaft is provided on the outer wall of the housing.

[0008] Preferably, the mud discharge chamber has a mud discharge port on one side and the drainage chamber has a drainage port on one side.

[0009] Preferably, the inner wall of the drainage cavity is provided with a support for supporting the horizontal plate, the side wall of the housing is provided with an inspection port for the horizontal plate to pass through, one end of the horizontal plate passes through the inspection port and is fixedly installed with a sealing plate, and the sealing plate is connected to the housing by bolts.

[0010] Preferably, the bottom of the drainage cavity is provided with a guide slope that is inclined toward the drainage pipe.

[0011] Beneficial effects

[0012] This utility model provides a solid-liquid separation device for tailings treatment, which has the following beneficial effects:

[0013] The tailings flow along the inclined screen plate under gravity, achieving solid-liquid separation. Simultaneously, a horizontally arranged plate within the drainage chamber has a conical opening and a filter screen at its bottom. After initial separation by the screen plate, the liquid flows into the drainage chamber and through the conical opening to the filter screen. The filter screen further filters out fine impurities, resulting in a purer liquid and improving the solid-liquid separation efficiency.

[0014] The electric slide rail drives the electric slider to move the moving frame along the screen plate. At the same time, the height of the cleaning roller can be adjusted by rotating the screw, so that the cleaning brush on the outer wall of the cleaning roller can fully contact the screen plate. During the movement, the cleaning brush can clean the solid impurities on the screen plate in time and push them into the sludge discharge chamber, avoiding the accumulation of solid impurities on the screen plate, preventing the screen plate from clogging, and ensuring that the screen plate can always maintain good filtration performance, ensuring the continuity and efficiency of the solid-liquid separation process.

[0015] The conveying assembly is driven by a motor to rotate the shaft, which in turn drives the conveying auger to rotate. Inside the sludge discharge chamber, the conveying auger can automatically transport the separated solid tailings to the sludge discharge port. This automated conveying method reduces manual operation, lowers labor costs and labor intensity, and improves work efficiency.

[0016] When the filter screen needs to be cleaned or replaced, or the inside of the drain chamber needs to be inspected, simply loosen the bolts on the sealing plate and pull the horizontal plate out from the inspection port. This design allows maintenance personnel to easily operate on the filter screen and the inside of the drain chamber without having to disassemble the entire device on a large scale, which greatly shortens the maintenance and repair time and reduces maintenance costs.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-2 This utility model provides a technical solution: a tailings treatment solid-liquid separation device, including a shell 1, a feed inlet 2 at the top of the shell 1, a screen plate 3 inclined inside the shell 1, the lower end of the screen plate 3 being fixedly connected to a partition plate 4, the partition plate 4 being fixedly disposed at the bottom inside the shell 1 and dividing the bottom of the shell 1 into a drainage chamber 6 and a sludge discharge chamber 5, the upper side of the shell 1 having an open structure, a cleaning assembly connected to the shell 1 being disposed above the screen plate 3, a horizontal plate 7 being horizontally disposed inside the drainage chamber 6, a conical opening being disposed on the horizontal plate 7, a filter screen 8 being disposed at the bottom of the conical opening, and a conveying assembly being disposed inside the sludge discharge chamber 5.

[0023] By adopting the above technical solution, the tailings enter the shell 1 from the feed inlet 2 and fall on the inclined screen plate 3. Under the action of gravity, the solid and liquid are initially separated. The partition plate 4 at the lower end of the screen plate 3 divides the bottom of the shell 1 into a drainage chamber 6 and a sludge discharge chamber 5, which are used to collect liquid and solid respectively. The cleaning component cleans the screen plate 3 to prevent blockage. The filter screen 8 in the drainage chamber 6 further filters the liquid. The conveying component transports the solid in the sludge discharge chamber 5 out.

[0024] In this embodiment, the cleaning assembly includes a pair of electric slide rails 9 on the outer walls of both sides of the housing 1. The slope of the electric slide rails 9 is the same as the slope of the sieve plate 3. A pair of electric sliders 10 are provided on the pair of electric slide rails 9. A movable frame 11 is installed between the pair of electric sliders 10. A screw 12 is screwed onto the movable frame 11. An adjusting frame 13 is rotatably installed at the lower end of the screw 12. A cleaning roller 14 is rotatably installed inside the adjusting frame 13. A cleaning brush 15 is provided on the outer wall of the cleaning roller 14. A pair of guide rods 16 are fixedly provided on the adjusting frame 13. A guide hole for the guide rods 16 to pass through is opened on the movable frame 11.

[0025] By adopting the above technical solution, the electric slide rail 9 drives the electric slider 10 to move the moving frame 11. The rotating screw 12 can adjust the height of the cleaning roller 14 so that the cleaning brush 15 contacts the screen plate 3 to clean the screen plate 3. The guide rod 16 and the guide hole ensure the stable movement of the adjusting frame 13. The above components realize the automatic cleaning function of the screen plate 3, effectively preventing the screen plate 3 from clogging. The cooperation between the electric slide rail 9 and the electric slider 10 enables the cleaning component to move along the screen plate 3, ensuring the continuity and efficiency of solid-liquid separation.

[0026] In this embodiment, the conveying assembly includes a rotating shaft 17 rotatably installed in the sludge discharge chamber 5, a conveying auger 18 is provided on the rotating shaft 17, and a motor 19 connected to one end of the rotating shaft 17 is provided on the outer wall of the housing 1.

[0027] By adopting the above technical solution, the motor 19 drives the rotating shaft 17 to rotate, which in turn drives the conveying auger 18 to rotate, transporting the solid tailings in the sludge discharge chamber 5 to the sludge discharge port 20, realizing the automatic conveying of solid tailings, reducing manual operation and improving work efficiency.

[0028] In this embodiment, the mud discharge chamber 5 is provided with a mud discharge port 20 on one side, and the drainage chamber 6 is provided with a drainage port 21 on one side.

[0029] In this embodiment, the inner wall of the drainage cavity 6 is provided with a support 22 for supporting the horizontal plate 7, and the side wall of the housing 1 is provided with an inspection port for the horizontal plate 7 to pass through. One end of the horizontal plate 7 passes through the inspection port and is fixedly installed with a sealing plate 23. The sealing plate 23 is connected to the housing 1 by bolts.

[0030] By adopting the above technical solution, the horizontal plate 7 is supported in the drainage chamber 6 by the support 22. When maintenance and repair are required, the bolts on the sealing plate 23 can be loosened to pull the horizontal plate 7 out from the inspection port, which improves the maintainability of the equipment, eliminates the need for a complicated disassembly process, shortens the maintenance and repair time, reduces maintenance costs, and ensures the long-term stable operation of the equipment.

[0031] In this embodiment, the bottom of the drainage cavity 6 is provided with a guide slope that is inclined toward the drainage pipe.

[0032] By adopting the above technical solution, the drainage efficiency is improved, liquid accumulation in the drainage chamber 6 is avoided, and the solid-liquid separation effect is guaranteed.

[0033] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0034] Example: During operation, tailings enter the device through the feed inlet 2 at the top of the shell 1 and fall onto the inclined screen plate 3. Under the action of gravity, the tailings flow downward on the screen plate 3. The liquid flows through the screen plate 3 into the drainage chamber 6, while the solid impurities remain on the screen plate 3 and continue to flow downward. The liquid flowing into the drainage chamber 6 passes through the conical opening on the horizontal plate 7 and is further filtered through the filter screen 8 to remove the fine impurities. Then it is discharged from the drainage outlet 21. The motor 19 drives the rotating shaft 17 to rotate, which drives the conveying auger 18 to transport the solid tailings in the sludge discharge chamber 5 to the sludge discharge outlet 20, thus completing the discharge of solids.

[0035] When it is necessary to clean the screen plate 3, rotate the screw 12, adjust the height of the cleaning roller 14 so that the cleaning brush 15 contacts the screen plate 3, start the electric slide rail 9, and the electric slider 10 drives the moving frame 11 to move along the screen plate 3 to clean the screen plate 3 and push solid impurities into the mud discharge chamber 5.

[0036] When the filter screen 8 needs to be cleaned or replaced, loosen the bolts on the sealing plate 23, pull out the horizontal plate 7 from the inspection port, and perform the corresponding operation. It is convenient to use.
