Technical Field

[0001] This utility model relates to the field of tailings treatment technology, specifically to an integrated device for tailings concentration and dry discharge. Background Technology

[0002] Tailings dry stacking refers to the process where tailings slurry output from the mineral processing flow is dewatered and concentrated to form slag with low water content, which is easy to settle and solidify and can be stored on site. The slag can be transported to a fixed location for dry stacking.

[0003] In existing technologies, tailings dry discharge equipment mainly includes vibrating dewatering screens and filters to separate the solid and liquid components of tailings slurry. However, these methods have the following shortcomings: 1. They lack a mechanism for further squeezing, dewatering, and automatically discharging the separated solid tailings, resulting in a large amount of water remaining in the tailings and requiring manual assistance to remove the material, leading to poor dewatering and removal effects; 2. They lack an auxiliary drying mechanism for the dewatered solid tailings, resulting in poor dry discharge effects.

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0032] Example 1

[0033] like Figures 1 to 3 As shown in this embodiment, a tailings concentration and dry discharge integrated device includes:

[0034] The box 1 has an opening at the bottom, two fixed brackets are fixedly connected to the bottom of both sides, a feed pipe is fixedly connected to the top, and a rectangular discharge hole 104 with an inclined bottom is opened on the right side.

[0035] The hydrophobic filter assembly is installed on the lower inner side of the housing 1 and is flush with the highest point of the bottom inner wall of the rectangular discharge hole 104. The hydrophobic filter assembly is used to filter and separate the solid and liquid after the tailings slurry is introduced, and to filter and intercept the solid tailings slag material at the top and discharge the liquid downward.

[0036] U-shaped support plate 2 is fixedly connected to the left side of the box body 1;

[0037] The PLC controller 201 is fixedly installed at the bottom of the U-shaped support plate 2;

[0038] The pressure-controlled extrusion dewatering and pushing assembly is installed inside the U-shaped support plate 2 and makes movable contact with the top left side of the hydrophobic filter assembly, and is electrically connected to the PLC controller 201.

[0039] The sealing assembly is installed on the housing 1 and is sealed and movable inside the rectangular discharge hole 104, and is electrically connected to the PLC controller 201.

[0040] The guide drying assembly is fixedly connected to the right side of the housing 1, and is connected to the rectangular discharge hole 104 and electrically connected to the PLC controller 201.

[0041] A water tank 100 is located below the tank body 1, with a drain valve fixed to its front bottom. The pressure-controlled extrusion dewatering and pushing assembly is used to control the pressure of the filtered and intercepted solid tailings material laterally under the control of the PLC controller 201, so as to further and quickly remove the residual water inside, and to push the material laterally after extrusion dewatering. The sealing assembly is used to seal the rectangular discharge hole 104, and is used to automatically unseal the rectangular discharge hole 104 under the control of the PLC controller 201 when pushing after extrusion, so that the solid tailings material can be moved to the right through the rectangular discharge hole 104. The guide and drying assembly is used to guide the removed tailings material outward and assist in its drying.

[0042] Furthermore, such as Figure 3As shown, the hydrophobic filtration assembly includes a stainless steel filter plate 103, four connecting rods 102, and an activated carbon filter plate 101. The stainless steel filter plate 103 is movably sleeved on the lower part of the inner side of the housing 1. The top of the stainless steel filter plate 103 is flush with the highest point of the bottom inner wall of the rectangular discharge hole 104. The activated carbon filter plate 101 is in movable contact with the bottom of the housing 1. The four connecting rods 102 are fixedly connected in a rectangular shape between the top of the activated carbon filter plate 101 and the bottom of the stainless steel filter plate 103. Two threaded grooves are opened on both sides of the bottom of the housing 1, and a knob bolt is screwed into the threaded groove. Two bolt holes are opened on both sides of the bottom of the activated carbon filter plate 101, and the threaded holes are movably sleeved on the corresponding knob bolts.

[0043] In this embodiment, the stainless steel filter plate 103, four connecting rods 102, activated carbon filter plate 101, knob bolts, and threaded grooves work together to filter out the liquid inside the tailings slurry after it is introduced, thus achieving solid-liquid separation of the tailings slurry. The activated carbon filter plate 101 further purifies the harmful substances contained in the water. The filtered and purified water is discharged downwards into the water receiving tank 100, achieving the effect of solid-liquid separation of the tailings slurry after it is introduced, filtering and intercepting the solid tailings slag at the top, and discharging the liquid downwards. In addition, the activated carbon filter plate 101 is installed and fixed by four knob bolts. Later, personnel can loosen and remove the four knob bolts to release the lock on the activated carbon filter plate 101, and then remove the activated carbon filter plate 101 and the stainless steel filter plate 103 for replacement.

[0044] Furthermore, such as Figure 1 and 3 As shown, the pressure-controlled extrusion dewatering and pushing assembly includes a first electric telescopic rod 203, a pressure sensor 204, and an L-shaped extrusion plate 202. The first electric telescopic rod 203 is fixedly installed on the inner left side of the U-shaped support plate 2. The extended end of the first electric telescopic rod 203 is fixedly connected to the pressure sensor 204. The right side of the pressure sensor 204 is movably inserted into the housing 1 and fixedly connected to the inner right side of the L-shaped extrusion plate 202. The bottom of the L-shaped extrusion plate 202 is in movable contact with the top left side of the stainless steel filter plate 103. The housing 1 is slidably sleeved on the L-shaped extrusion plate 202. The front, rear, and right inner walls of the L-shaped extrusion plate 202 are in movable contact with the front, rear, and left inner walls of the housing 1, respectively. The first electric telescopic rod 203 and the pressure sensor 204 are both electrically connected to the PLC controller 201.

[0045] In this embodiment, a rectangular sliding hole is provided on the left inner wall of the housing 1, which is slidably connected to the outer side of the L-shaped extrusion plate 202, so as to guide the L-shaped extrusion plate 202 to slide laterally; a rectangular through hole is provided on the left inner wall of the housing 1, and the pressure sensor 204 is located in the rectangular through hole and does not contact its inner side, so as to allow the pressure sensor 204 to pass through.

[0046] In this implementation scheme, the first electric telescopic rod 203, pressure sensor 204, and L-shaped extrusion plate 202 work together. The PLC controller 201 is pre-set to control the closing pressure value of the first electric telescopic rod 203, and is pre-set to restart it three seconds after reaching the pressure value. When the human-machine interface of the PLC controller 201 is turned on, the PLC controller 201 first controls the first electric telescopic rod 203 to start forward, causing it to move the L-shaped extrusion plate 202 to the right via the pressure sensor 204. The L-shaped extrusion plate 202 pushes the filtered and intercepted solid tailings material laterally to the right, further quickly removing the residue under the pushing force. The water that remains, under the resistance created by the pushing, is detected by the pressure sensor 204, which detects the squeezing force applied by the first electric telescopic rod 203. This force is converted into a standard electrical signal and transmitted to the PLC controller 201. The PLC controller 201 converts the received standard electrical signal into an actual pressure value through analog-to-digital conversion. When the pressure value reaches the preset value, the PLC controller 201 controls the first electric telescopic rod 203 to close, and then controls it to start forward again after three seconds. This causes the L-shaped extrusion plate 202 to move to the right and push laterally after three seconds, thus achieving the effect of lateral pressure control and pushing to quickly discharge the residual liquid from the filtered and intercepted solid tailings material. After extrusion dehydration and unsealing on the right side, the material is pushed out laterally.

[0047] Furthermore, such as Figure 2 and 3 As shown, the sealing assembly includes an L-shaped sealing plate 301 and a second electric telescopic rod 3. A rectangular guide hole communicating with a rectangular discharge hole 104 is provided on the top right side of the housing 1. The L-shaped sealing plate 301 is slidably fitted in the rectangular guide hole and the rectangular discharge hole 104. The bottom of the L-shaped sealing plate 301 is set as an inclined surface and is squeezed and fitted tightly against the bottom inner wall of the rectangular discharge hole 104. The second electric telescopic rod 3 is fixedly installed on the top right side of the housing 1. The extended end of the second electric telescopic rod 3 is fixedly connected to the top inner wall of the L-shaped sealing plate 301. The second electric telescopic rod 3 is electrically connected to the PLC controller 201.

[0048] In this embodiment, the outer side of the L-shaped sealing plate 301 is bonded and covered with a sealing rubber. The outer side of the sealing rubber slides and closely contacts the inner wall of the rectangular guide hole and the rectangular discharge hole 104, thereby achieving a sliding seal between the outer side of the L-shaped sealing plate 301 and the inner side of the rectangular guide hole and the rectangular discharge hole 104.

[0049] In this implementation scheme, the L-shaped sealing plate 301 and the second electric telescopic rod 3 work together. The PLC controller 201 pre-sets a pressure value to control the forward start of the second electric telescopic rod 3. This pressure value is the same as the controlled pressure pushing pressure value. It is set to control the first electric telescopic rod 203 and the second electric telescopic rod 3 to start in reverse and reset sequentially after five seconds of opening, with a two-second interval between each two seconds. When the controlled pressure pushing pressure value reaches the preset value, the PLC controller 201 controls the second electric telescopic rod 3 to start forward, driving the L-shaped sealing plate 301 to move upward and unseal the rectangular discharge hole 104, thereby improving efficiency. The system provides the conditions for pushing solid tailings material out horizontally. After the program-set running time reaches five seconds, the PLC controller 201 first controls the first electric telescopic rod 203 to start and reset in the reverse direction, driving the L-shaped extrusion plate 202 to move back to the left and reset. Then, two seconds later, it controls the second electric telescopic rod 3 to start and reset in the reverse direction, driving the L-shaped sealing plate 301 to move down and re-seal the rectangular discharge hole 104. This achieves the effect of automatically unsealing the rectangular discharge hole 104 after pushing and automatically sealing it after pushing and discharging, so that the solid tailings material can move to the right through the rectangular discharge hole 104 when being pushed.

[0050] Furthermore, such as Figure 2 and 3 As shown, the guide drying assembly includes a rectangular guide pipe 4, an inclined filter plate 401, two hot air blowers 404, a vibration motor 403, and a water guide box 402. The rectangular guide pipe 4 is inclined and fixedly connected to the right side of the housing 1 and is connected to the rectangular discharge hole 104. The inclined filter plate 401 is embedded in the bottom inner wall of the rectangular guide pipe 4. The water guide box 402 is inclined and fixedly connected between two fixed brackets on the right side and is located below the inclined filter plate 401 and above the water receiving tank 100. The two hot air blowers 404 are both embedded and fixedly fixed on the top left side of the rectangular guide pipe 4. The bottom of the hot air blower 404 is the hot air outlet and is connected to the inside of the rectangular guide pipe 4. The vibration motor 403 is fixedly installed on the top of the rectangular guide pipe 4. The two hot air blowers 404 and the vibration motor 403 are all electrically connected to the PLC controller 201.

[0051] In this embodiment, two mounting through holes are provided on the top left side of the rectangular guide pipe 4, which are respectively fixedly connected to the outside of the corresponding hot air blower 404;

[0052] In this implementation scheme, the rectangular guide pipe 4, inclined filter plate 401, two hot air blowers 404, vibration motor 403, and water guide box 402 work together. The PLC controller 201 is pre-set to control the starting pressure of the two hot air blowers 404 and vibration motor 403. This pressure value is the same as the controlled pressure pushing pressure value, and is set to shut down after twenty seconds. When the controlled pressure pushing pressure value reaches the preset value, the PLC controller 201 controls the two hot air blowers 404 and vibration motor 403 to start, and the solid tailings material pushed to the right is discharged into the rectangular guide pipe 4. The activated vibration motor 403 vibrates and transmits the high-frequency micro-amplitude hard vibration resonance force to the rectangular guide pipe 4. The high-frequency hard vibration of the rectangular guide pipe 4, combined with its inclined setting, guides the solid tailings material downwards and to the right, while the two hot air blowers 404 blow hot air downwards. For the auxiliary drying of solid tailings slag, the inclined filter plate 401 further filters the residual water downwards into the water guide box 402, and then guides it into the water receiving tank 100 through the water guide box 402. After 20 seconds, the PLC controller 201 controls the two hot air blowers 404 and the vibration motor 403 to shut down, waiting for the next operation of the PLC controller 201 to automatically run each step in sequence. This achieves the effect of auxiliary drying, further dewatering and vibration guiding of tailings slag when it is removed. Personnel can simply place a receiving box or conveying device on the lower right of the rectangular guide pipe 4. By using the coordinated application of sequential water filtration, pressure-controlled pushing dewatering, unsealing and horizontal pushing discharge, and guided auxiliary drying, there is no need for personnel to remove the solid tailings slag from the inside, which improves the convenience of use and the concentration and dewatering effect, forming an integrated application effect of tailings dewatering, concentration and dry discharge.

[0053] Furthermore, the inclined filter plate 401 is fixedly embedded in the bottom inner wall of the rectangular guide pipe 4, and a rectangular embedding hole is opened on the bottom inner wall of the rectangular guide pipe 4 to be fixedly connected to the outer side of the inclined filter plate 401; by using the fixed embedding method, when subsequent personnel clean the inclined filter plate 401, they can directly use an external air gun to back-blow and clean it from bottom to top.

[0054] It should be noted that: the PLC controller 201 is preferably a Siemens S7-200SMART programmable controller with an integrated analog input module, which can directly receive the standard electrical signal output by the pressure sensor and use its own analog-to-digital conversion function to accurately convert the electrical signal into the actual pressure value; the pressure sensor 204 is preferably a Transcell BSS series plate (pressure) load cell; and by using the time control function of the programmable controller, the pause time from closing to starting of the first electric telescopic rod 203, the pause time from starting to resetting of the second electric telescopic rod 3, and the time interval from starting to closing of the hot air blower 404 and the vibration motor 403 can be set through programming, so as to control the start of each accordingly, thereby realizing the time control function of the corresponding steps. The above operations are all conventional applications of the programmable controller and are basic and well-known technical means of the programmable controller, which will not be described in detail here.

[0055] The electrical connection between the first electric telescopic rod 203, the second electric telescopic rod 3, and the PLC controller 201 is achieved through wires and servo drivers. The preferred servo driver is a Siemens V90 servo driver, a commonly used driver for controlling motors and electric actuators in conjunction with Siemens programmable controllers, satisfying the programmable controller's direct control requirements for the first and second electric telescopic rods 203. The electrical connection between the hot air blower 404 and the vibration motor 403 and the PLC controller 201 is also achieved through wires and relays, satisfying the programmable controller's direct control requirements for the hot air blower 404 and the vibration motor 403. This method of establishing an electrical connection controlled by the PLC controller 201 through direct wire connection is a mature and well-known technology for conventional wired program control of the controller, and will not be elaborated further.

[0056] This embodiment can separate the solid and liquid components of the tailings slurry after it is introduced, filter and intercept the solid tailings slag at the top and discharge the liquid downwards. It can also control the pressure and push the filtered and separated solid tailings slag to quickly discharge the residual liquid, and push the ore laterally after extrusion and dewatering to reduce the phenomenon of a large amount of water remaining in the tailings slag, improve the dewatering effect and the ease of removal. It can also assist in drying, further dewatering and vibration guiding the tailings slag during removal. By using the synergistic application of sequential filtration, pressure-controlled extrusion dewatering, unsealing and horizontal pushing discharge, and guided discharge to assist drying, the ease of use is improved.

[0057] The method of use in this embodiment is as follows: When the tailings thickening and dry discharge integrated device is used, the stainless steel filter plate 103 filters out the liquid inside the tailings slurry after it is introduced, thereby achieving solid-liquid separation of the tailings slurry. The activated carbon filter plate 101 further purifies the harmful substances contained in the water. The filtered and purified water is discharged downward into the water receiving tank 100, thereby achieving the effect of solid-liquid separation of the tailings slurry after it is introduced, filtering and intercepting the solid tailings slag at the top and discharging the liquid downward.

[0058] The PLC controller 201 is pre-set with pressure values ​​to control the closing of the first electric telescopic rod 203, the opening of the second electric telescopic rod 3, the opening of the hot air blower 404, and the opening of the vibration motor 403. It is also pre-set to control the first electric telescopic rod 203 to start forward again after a three-second interval after reaching the pressure value and to control the first electric telescopic rod 203 to start in reverse and reset after a two-second interval after the second electric telescopic rod 3 has been open for five seconds. The hot air blower 404 and the vibration motor 403 are controlled to shut down after twenty seconds of operation. When the human-machine interface of the PLC controller 201 is turned on, the PLC controller 201 first controls the first electric telescopic rod 203 to start forward, causing it to move the L-shaped extrusion plate 202 to the right via the pressure sensor 204. The L-shaped extrusion plate 202 pushes the filtered and intercepted solid tailings material laterally to the right, further quickly removing residual water under the pushing force. Under the resistance formed by the pushing, the pressure sensor 204 detects the first... The extrusion force applied by the electric telescopic rod 203 is converted into a standard electrical signal and transmitted to the PLC controller 201. The PLC controller 201 converts the received standard electrical signal into an actual pressure value through analog-to-digital conversion. When the pressure value reaches the preset value, the PLC controller 201 controls the first electric telescopic rod 203 to close, the second electric telescopic rod 3 to open, the hot air blower 404 to turn on, and the vibration motor 403 to turn on. At this time, the second electric telescopic rod 3 drives the L-shaped sealing plate 301 to move upward and unseal the rectangular discharge hole 104. Three seconds later, the PLC controller 201 controls the first electric telescopic rod 203 to start forward again and drive the L-shaped extrusion plate 202 to move to the right again to push the tailings slag after extrusion and dewatering. This achieves the effect of controlling the pressure and pushing the solid tailings slag separated by filtration and interception to quickly discharge the residual liquid, and pushes the ore out laterally after extrusion and dewatering. This reduces the phenomenon of a large amount of water remaining in the tailings slag and eliminates the need for manual removal of the material, improving the dewatering effect and the ease of removal.

[0059] After the program's set running time reaches five seconds, the PLC controller 201 first controls the first electric telescopic rod 203 to reverse and reset, driving the L-shaped extrusion plate 202 to move back to the left and reset. Then, two seconds later, it controls the second electric telescopic rod 3 to reverse and reset, driving the L-shaped sealing plate 301 to move down and re-seal the rectangular discharge hole 104, achieving the effect of automatic sealing after the material is pushed out, so that the solid tailings material can be pushed out to the right through the rectangular discharge hole 104. The tailings material moving to the right enters the rectangular guide pipe 4. When the two hot air blowers 404 and the vibration motor 403 are turned on, the vibration of the turned-on vibration motor 403 is transmitted to the rectangular guide pipe 4 with a high-frequency micro-amplitude hard vibration resonance force. The high-frequency hard vibration of the rectangular guide pipe 4, combined with its tilt setting, realizes the guide of the solid tailings material to the lower right. 4. Hot air is blown down to assist in the drying of solid tailings slag. The inclined filter plate 401 further filters the residual water downward into the water guide box 402, and then guides it into the water receiving tank 100. After 20 seconds, the PLC controller 201 controls the two hot air blowers 404 and the vibration motor 403 to shut down, waiting for the next operation of the PLC controller 201 to automatically run each step in sequence. This achieves the effect of assisting in the drying, further dehydration and vibration guiding of the tailings slag when it is removed. Personnel can simply place a receiving box or conveying device on the lower right of the rectangular guide pipe 4. By using the coordinated application of sequential water filtration, pressure-controlled pushing dehydration, unsealing and horizontal pushing discharge, and guided auxiliary drying, there is no need for personnel to remove the solid tailings slag from the inside, which improves the convenience of use and the concentration and dehydration effect, forming an integrated application effect of tailings dehydration, concentration and dry discharge.
