Description

Technical Field

[0001] This utility model relates to the field of tailings recycling technology, specifically a new type of high-efficiency tailings dewatering equipment. Background Technology

[0002] In the field of geology and mining, the main method for treating tailings is to utilize tailings dams. Tailings slurry enters the tailings dam for sedimentation, where water and solid particles gradually separate. Solid particles settle at the bottom, while the upper layer is mainly clear water. As tailings slurry continues to flow in, the clear water overflows and is recycled, while the particles gradually settle to the bottom and remain in the tailings dam, enabling continuous operation. This method of tailings treatment is inexpensive but poses significant safety hazards. Tailings dams themselves are sources of debris flows. Due to the fine particle size, large surface area, and high moisture content of the tailings, most of the moisture must be removed to meet the requirements of subsequent processes for utilization. Therefore, filtration and dewatering equipment is needed to pre-dewater the tailings slurry to reduce its moisture content.

[0003] Existing tailings slurry dewatering equipment simply uses internal filter elements to filter the liquid and reduce its moisture content. However, it has the following shortcomings: 1. After filtration, the tailings fragments need to be removed separately, lacking an integrated automatic discharge mechanism, resulting in poor ease of use; 2. After filtration, there is no integrated cleaning and unblocking mechanism for the internal filter elements, leaving a large amount of solid slag residue on the filter elements, which can easily cause blockages and affect reuse, resulting in poor cleanliness after use. In view of this, this application proposes a new type of high-efficiency tailings dewatering equipment to solve the above-mentioned problems. Utility Model Content

[0030] Example 1

[0031] like Figures 1 to 2 As shown in this embodiment, a novel high-efficiency tailings dewatering device includes:

[0032] The feeding cylinder 1 is inclined, and stainless steel filter screens 101 are embedded and fixed on its top inner wall, bottom inner wall, front inner wall and rear inner wall.

[0033] The outer shell 3 is sealed and rotated on the outside of the feed cylinder 1. Its bottom inner wall is set as a conical structure. The bottom inner wall of the outer shell 3 is connected to and fixed with a drainage pipe 301.

[0034] A circular support sleeve 102 is rotatably installed on the left side of the feed cylinder 1. The left side is configured as a sealing structure, and the top of the sleeve is connected to and fixedly connected to a feed hopper 103. Rectangular support plates 6 are welded and fixed to the bottom of the circular support sleeve 102 and the bottom of the circular outer shell 3. The bottoms of the two rectangular support plates 6 are connected to the same base 601. The inner side of the feed cylinder 1 is provided with an annular groove with an opening on the left side, and the outer side of the circular support sleeve 102 is provided with an annular groove with an opening on the right side. A first sealing bearing is fixedly fitted inside the annular groove, and the inner ring of the first sealing bearing is fixedly fitted to the inner wall of the annular groove.

[0035] A spiral conveyor assembly is installed inside the circular support sleeve 102 and the feed cylinder 1. The spiral conveyor assembly is used to push and convey the tailings slurry to the right into the feed cylinder 1 after the tailings slurry is fed into the circular support sleeve 102 through the feed hopper 103, and then convey and discharge it to the right. Four stainless steel filter screens 101 are set to filter out water as the tailings slurry moves in the feed cylinder 1. By using the combination of stirring and long-distance stainless steel filter screens 101 to filter water, efficient dewatering is achieved, effectively reducing the water content of the tailings slurry. The dewatered water is discharged to the outside through the drain pipe 301.

[0036] The rotary support assembly is fixedly connected to the left side of the circular outer shell 3 and fixedly sleeved on the outside of the feed cylinder 1 and the circular support sleeve 102. The rotary support assembly is used to support the circular support sleeve 102 and the feed cylinder 1, and to drive the feed cylinder 1 to rotate after use, thereby driving the four stainless steel filter screens 101 to rotate.

[0037] The backflushing cleaning assembly is fixedly connected between the inner walls of both sides of the circular outer shell 3 and located above the feed cylinder 1; the backflushing cleaning assembly is used to backflush and clean the four rotating stainless steel filter screens 101 after use.

[0038] In this embodiment, the outer shell 3 has through holes on both sides, and a second sealing bearing is fixedly fitted inside the through hole. The inner ring of the second sealing bearing is fixedly fitted to the outer side of the feed cylinder 1, so as to achieve the effect of sealing and rotating the feed cylinder 1 from the outside. The feed cylinder 1 has fitting holes on the top inner wall, bottom inner wall, front inner wall and rear inner wall, and the inner wall of the fitting hole is fixedly connected to the outer side of the corresponding stainless steel filter screen 101.

[0039] Furthermore, the base 601 is welded to the bottom of the two rectangular support plates 6.

[0040] Furthermore, such as Figure 2As shown, the screw conveyor assembly includes a central shaft 201, a screw conveyor blade 202, a U-shaped seat, and a drive motor 2. The central shaft 201 is rotatably fitted into the left inner wall of the circular support sleeve 102. The central shaft 201 is rotatably installed between the front and rear inner walls of the feeding cylinder 1. The screw conveyor blade 202 is welded and sleeved on the central shaft 201.

The output shaft of the drive motor 2 is fixedly connected to the left end of the central shaft 201.

[0041] In this embodiment, a circular hole is provided on the inner wall of the left side of the circular support sleeve 102, and a third sealing bearing is fixedly fitted in the circular hole. Support rods are fixedly connected to the inner walls of the front and rear sides of the feed cylinder 1, and a support bearing is fixedly connected between the two support rods. The inner ring of the support bearing and the inner ring of the third sealing bearing are fixedly fitted to the outer side of the central shaft 201, so as to achieve the effect of rotating the central shaft 201.

[0042] In this embodiment, the central shaft 201, the spiral conveyor blade 202, the U-shaped seat and the drive motor 2 work together to drive the central shaft 201 to rotate. The central shaft 201 drives the spiral conveyor blade 202 to rotate. When the spiral conveyor blade 202 rotates, it agitates the incoming tailings slurry and pushes it to the right in a spiral motion for conveying.

[0043] Furthermore, such as Figure 1 and 2 As shown, the rotary support assembly includes a fixed box 5, an external gear ring 501, a gear 502, and a brake motor 503. The right side of the fixed box 5 is set as an opening and is fixedly connected to the left side of the circular outer shell 3. The fixed box 5 is fixedly sleeved on the outside of the circular support sleeve 102. The external gear ring 501 is located inside the fixed box 5 and is fixedly sleeved on the outside of the feed cylinder 1. The gear 502 meshes with the bottom of the external gear ring 501. The brake motor 503 is fixedly installed on the bottom left side of the fixed box 5. The output shaft of the brake motor 503 is fixedly connected to the left side of the gear 502.

[0044] In this embodiment, the left side of the fixing box 5 is provided with a fitting hole for fixed connection with the outer side of the round support sleeve 102;

[0045] In this embodiment, the fixed box 5, the outer gear ring 501, the gear 502 and the brake motor 503 work together to fix and support the circular support sleeve 102 on the left side of the circular outer shell 3. After use, the brake motor 503 drives the gear 502 to rotate, the gear 502 drives the outer gear ring 501 that meshes with it to rotate, the outer gear ring 501 drives the feed cylinder 1 to rotate, and the feed cylinder 1 drives the four stainless steel filter screens 101 to rotate.

[0046] Furthermore, such as Figure 2As shown, the backflushing cleaning assembly includes a horizontal pipe 401, multiple high-pressure nozzles 402, an L-shaped pipe, and a water pump 4. The horizontal pipe 401 is welded and fixed between the inner walls of both sides of the circular outer shell 3. The multiple high-pressure nozzles 402 are all located above the feed cylinder 1 and are connected and fixed at equal intervals at the bottom of the horizontal pipe 401. The water pump 4 is fixedly installed on the top of the circular outer shell 3. The L-shaped pipe is connected and fixed to the water outlet end of the water pump 4. The bottom end of the L-shaped pipe extends into the circular outer shell 3 and is connected and fixed to the top of the horizontal pipe 401. The water inlet end of the water pump 4 is connected and fixed with a suction hose.

[0047] In this embodiment, the top of the circular outer shell 3 is provided with a through hole that makes active contact with the outside of the L-shaped tube;

[0048] In this implementation scheme, the horizontal pipe 401, multiple high-pressure nozzles 402, L-shaped pipe, and water pump 4 work together. After use, one end of the suction hose is placed in an external water source or connected to an external water supply pipe. The water pump 4 draws water from the external source through the suction hose and pumps it into the horizontal pipe 401 through the L-shaped pipe. The water is sprayed downwards through multiple high-pressure nozzles 402 to backwash and clean the four rotating stainless steel filter screens 101 in sequence. This avoids the phenomenon that a large amount of solid residue remains in the stainless steel filter screens 101 and inside, which affects subsequent use. It improves the internal cleanliness after use and eliminates the need for manual cleaning, thus improving the convenience and automation of cleaning.

[0049] It should be noted that the rectangular support plate 6, the feed cylinder 1, the round outer shell 3, the round support sleeve 102, the central shaft 201, the spiral conveyor blade 202, the fixed box 5, the external gear ring 501, the gear 502, the horizontal pipe 401, the high-pressure nozzle 402, and the L-shaped pipe are all preferably made of stainless steel. The advantages of stainless steel, such as high hardness, high wear resistance, corrosion resistance, and good maintenance-free performance, are utilized to ensure long-term connection application and support stability.

[0050] Regarding power supply, the tailings dewatering treatment site is a tailings processing site, and there is no shortage of power supply measures on site. All electrical components of this device are connected to the mains power on site, and are connected to the power input interface of each device through conventional power distribution devices such as circuit breakers, contactors, and power modules (not marked in the figure) to form a complete power supply circuit. This power supply scheme is a conventional power distribution method for industrial equipment, and all are conventional, mature and well-known methods, so it will not be described in detail here. In addition, when used in some conditions such as being carried on a vehicle, it can be used with commercially available diesel generators and other mobile power supply facilities for power supply.

[0051] This embodiment can efficiently filter and dehydrate water and automatically discharge solid tailings during filtration, reducing the moisture content of the tailings slurry. It eliminates the need for separate operation to remove the tailings, improving ease of use. It also allows for convenient backflushing and unclogging of the four stainless steel filter screens 101 after use, reducing the likelihood of blockage caused by residual solids on the inside, which could affect subsequent use. This improves the internal cleanliness after use and eliminates the need for manual internal cleaning, enhancing the convenience and automation of cleaning.

[0052] The usage method of this embodiment is as follows: When using this new type of high-efficiency tailings dewatering equipment, the tailings slurry is fed into the circular support sleeve 102 through the feed hopper 103. The drive motor 2 is started to drive the central shaft 201 to rotate. The central shaft 201 drives the spiral conveyor blade 202 to rotate. When the spiral conveyor blade 202 rotates, it agitates and pushes the incoming tailings slurry to the right, agitating and pushing it to the right into the feed cylinder 1. The tailings slurry is then discharged to the right through the right side of the feed cylinder 1. Four stainless steel filter screens 101 filter out the water as the tailings slurry moves within the feed cylinder 1. The filtered water is discharged outward through the drain pipe 301. Connecting the drain pipe 301 to an external hose allows for designated drainage and recycling of the water. By using agitation combined with the long-distance stainless steel filter screens 101 for integrated water filtration, high-efficiency water filtration and dewatering are achieved, effectively reducing the moisture content of the tailings slurry. The solid tailings are automatically discharged during filtration, eliminating the need for separate removal of the tailings, thus improving ease of use.

[0053] After use, personnel start the brake motor 503 and water pump 4, placing one end of the suction hose into an external water source or connecting it to an external water supply pipe. When the brake motor 503 starts, it drives the gear 502 to rotate, which in turn drives the meshing outer gear ring 501 to rotate. The outer gear ring 501 drives the feed cylinder 1 to rotate, which in turn drives the four stainless steel filter screens 101 to rotate. The water pump 4 draws water from the external source through the suction hose and pumps it into the horizontal pipe 401 through the L-shaped pipe. The water is sprayed downwards through multiple high-pressure nozzles 402, which backflushes and cleans the four rotating stainless steel filter screens 101 in sequence. This achieves a convenient and integrated backflushing and cleaning effect on the four stainless steel filter screens 101 after use, reducing the phenomenon of large amounts of solid residue remaining on the inside of the stainless steel filter screens 101 causing blockage and affecting subsequent use. It also improves the internal cleanliness after use, eliminating the need for manual cleaning and increasing the convenience and automation of cleaning.

[0054] Example 2

[0055] like Figures 3 to 4As shown, this embodiment differs from Embodiment 1 in that: the base 601 is detachably connected to the bottom of the two rectangular support plates 6, and rectangular sleeves 602 are welded and fixed on both sides of the top of the base 601. The bottoms of the two rectangular support plates 6 are respectively movably fitted into the corresponding rectangular sleeves 602. Threaded grooves are opened on the bottom of the opposing sides of the two rectangular support plates 6, and knob bolts 603 are threaded into the threaded grooves. Threaded holes are opened on the opposing sides of the two rectangular sleeves 602, and the threaded holes are threaded onto the corresponding knob bolts 603.

[0056] This embodiment allows for the separate assembly and disassembly of the base 601. The detachable base 601 allows personnel to replace the base carrier with one equipped with wheels or a base carrier of different heights as needed, thereby enabling more flexible application and improving usability.

[0057] The usage method of this embodiment is as follows: Unlike Embodiment 1, it also has the following functions: Utilizing the provided rectangular sleeve 602, threaded groove, threaded hole, and knob bolt 603, the rectangular sleeve 602 secures and positions the corresponding rectangular support plate 6. The knob bolt 603, through its threaded connection with the threaded groove, locks the rectangular support plate 6 to the rectangular sleeve 602. When the knob bolt 603 is rotated in the opposite direction to separate from the threaded groove, the fixation between the rectangular support plate 6 and the rectangular sleeve 602 is released, allowing the rectangular support plate 6 to be moved upwards and separated from the corresponding rectangular sleeve 602. This achieves the effect of detachable and detachable base 601. The detachable base 601 allows personnel to subsequently replace the base carrier with a wheeled one or a base carrier of different heights as needed, enabling further flexible application.
