Description

Technical Field

[0001] The invention relates to the technical field of tailings water treatment, and in particular to a tailings thickener with a tailings lowering aid structure. Background Art

[0002] Tailings water refers to wastewater containing a large amount of suspended and dissolved minerals produced after the ore is physically and chemically treated during the mineral processing process. In the prior art, thickeners are generally used to treat tailings water.

[0003] In the patent "A deep cone thickener flocculant adding device" with application number "202323424976.5", the scheme is to set the flocculant storage box and the support frame to be close to each other, and the flocculant storage box is connected to the upper cover through a connecting pipe. When the adjustment component is opened, the flocculant can be controlled and discharged into the fixed installation box. However, this scheme still has certain defects: This solution will add flocculants to the surface of the tailings water at one time. Although this method does not affect the subsequent sedimentation of the tailings water, when the flocculant and tailings water come into contact, that is, during the mixing process of the flocculant and tailings water, the flocculant needs to enter the bottom of the tailings water from the upper surface of the tailings water so that all the tailings water can contact the flocculants. However, this method prolongs the mixing time of the flocculant and tailings water, reduces the sedimentation rate of the tailings water, and this method can easily lead to uneven distribution of the flocculant, resulting in uneven sedimentation inside the tailings water.

[0007] Preferably, the shell side wall is fixedly connected with a liquid storage frame, the inner walls of the two pump liquid frames are connected to the inner walls of the liquid storage frame through a one-way suction pipe, and flocculant is arranged in the liquid storage frame.

[0009] Preferably, an oil pumping mechanism is provided on the fixed frame, and the oil pumping mechanism includes two oil pumping frames fixedly connected to the side walls of the fixed frame, hydraulic oil is provided in the oil pumping frames, and the inner walls of the two oil pumping frames are sealed and slidably connected with a second T-shaped plate, and the side wall of the second T-shaped plate located outside the oil pumping frame is rotatably connected to the lower end of the spoiler close to it through a fifth plate, and the top of the oil pumping frame is connected to the bottom of the oil pumping chamber close to it through a connecting pipe.

[0010] Preferably, the lower end of the fixed frame is rotatably connected to a threaded barrel, a plurality of second landing aid plates are fixedly connected to the side wall of the threaded barrel, the lower end of the electric push rod is fixedly connected to a rifle rod, and the side wall of the rifle rod is threadedly connected to the inner wall of the threaded barrel.

[0011] Preferably, grooves are provided at the upper and lower ends of the plurality of second landing aid plates, the inner walls of the grooves are sealingly and slidably connected with partitions, the side walls of the partitions are elastically connected to the inner walls of the grooves through a plurality of magnetic springs, and the plurality of magnetic springs are electrically connected to an external control mechanism.

[0013] Preferably, a bottom cover is fixedly mounted on the lower end of the machine body by a plurality of bolts.

[0014] Preferably, a one-way valve is installed in the one-way liquid outlet pipe to only allow flocculant to enter the pump liquid cavity from the pump liquid frame, and a one-way liquid suction pipe is installed to only allow flocculant to enter the pump liquid frame from the liquid storage frame.

[0015] Compared with the prior art, the present invention has the following advantages: 1. A descent-assisting mechanism and a liquid pumping mechanism are provided. When the two first plates slide back and forth, the flocculant flows out through a plurality of liquid outlets and is continuously thrown upward as the spoiler rotates up and down, so that the flocculant is initially mixed with the tailings water. As the two spoilers rotate continuously, the time for the tailings water to fall into the body is increased, which further increases the initial mixing degree of the flocculant with the tailings water and accelerates the subsequent sedimentation of the tailings water. This avoids the prior art practice of adding the flocculant to the surface of the tailings water at one time, which results in the flocculant needing to enter the bottom of the tailings water from the upper surface of the tailings water during the mixing process of the flocculant and the tailings water, thereby prolonging the mixing time of the flocculant and the tailings water and reducing the sedimentation rate of the tailings water. In addition, this method can easily lead to uneven distribution of the flocculant, resulting in uneven sedimentation inside the tailings water.

[0016] 2. A first lowering assisting plate and an oil pumping mechanism are provided. When the two spoilers rotate up and down, the two spoilers drive the second T-shaped plate to slide back and forth on the inner wall of the oil pumping frame through the fifth plate, so that the space in the oil pumping frame is intermittently increased or decreased. At this time, the hydraulic oil will flow back and forth in the oil pumping frame and the oil pumping cavity through the connecting pipe, so that the slide plate slides back and forth on the inner wall of the strip cavity. At this time, multiple toothed plates will drive multiple vertical rods to rotate through multiple gears, and drive multiple first lowering assisting plates to rotate, thereby further accelerating the sedimentation of the tailings water.

[0017] 3. Set up partitions and magnetic springs. When the electric push rod stops extending and retracting, it means that the flocculant and tailings water are evenly mixed. Now just wait for the tailings water to settle. At this time, the external control mechanism controls multiple magnetic springs to cut off power and extend, so that the partition is moved out of the groove. At this time, the side walls of the two adjacent partitions above and below are fitted together, which hinders the flow of tailings water, stops the flow of tailings water as soon as possible, and accelerates the static sedimentation of tailings water.

[0022] The landing-assisting mechanism includes a fixed frame 4 fixedly connected to the top of the shell 2, and the side walls of the fixed frame 4 that are away from each other are rotatably connected to spoilers 5 through a rotating shaft. The inner walls of the fixed frame 4 below the two spoilers 5 are penetrated and slidably connected with a first plate 7, and the side walls of the first plate 7 outside the fixed frame 4 are rotatably connected to the lower ends of the spoilers 5 close to it through a second plate 8. An electric push rod 9 is fixedly connected to the upper end of the shell 2, and the side walls of the movable shaft of the electric push rod 9 are rotatably connected to the upper ends of the two first plates 7 through two third plates 10. A strip cavity 6 is opened in the spoiler 5, and a slide plate 11 is sealed and slidably connected to the inner wall of the strip cavity 6. The slide plate 11 divides the strip cavity 6 into a pump oil cavity 12 and a pump liquid cavity 13 (such as Figure 6 As shown in FIG. 1 , a plurality of liquid outlets 17 are provided at the inner top of the pump liquid chamber 13 away from the slide plate 11.

[0023] Tailings water is added into the shell 2 through the two water inlets 3, and the tailings water will directly impact on the two spoiler plates 5. At this time, the electric push rod 9 is adjusted to continuously extend and retract. At this time, the electric push rod 9 will drive the two spoiler plates 5 to rotate up and down through the two third plates 10, the two first plates 7 and the two second plates 8, and the tailings water impacting the two spoiler plates 5 will be continuously thrown upwards.

[0024] A pumping mechanism is provided on the fixed frame 4, and the pumping mechanism includes two pumping frames 14 fixedly connected to the lower end of the fixed frame 4, the inner walls of the two pumping frames 14 are sealed and slidably connected with the first T-shaped plate 15, the lower ends of the two first plates 7 are fixedly connected with the fourth plate 20, and the fourth plate 20 is fixedly connected to the side wall of the first T-shaped plate 15 adjacent to it, and the inner bottom of the pumping frame 14 is connected to the inner bottom of the pumping chamber 13 through a one-way liquid outlet pipe 16.

[0025] The side wall of the housing 2 is fixedly connected to a liquid storage frame 18, and the inner walls of the two pump liquid frames 14 are connected to the inner wall of the liquid storage frame 18 through a one-way suction pipe 19 (such as Figure 5 As shown in FIG. 1 ), a flocculant is provided in the liquid storage frame 18 .

[0026] A one-way valve is installed in the one-way liquid outlet pipe 16 to allow only flocculant to enter the pump liquid chamber 13 from the pump liquid frame 14 . A one-way liquid suction pipe 19 is installed to allow only flocculant to enter the pump liquid frame 14 from the liquid storage frame 18 .

[0027] When the two first plates 7 slide back and forth, the two fourth plates 20 and the two first T-shaped plates 15 will slide back and forth on the inner walls of the two pump liquid frames 14, so that the space in the two pump liquid frames 14 is intermittently increased or decreased. At this time, the two pump liquid frames 14 can squeeze the flocculant in the liquid storage frame 18 into the pump liquid cavity 13 through the one-way suction pipe 19 and the one-way liquid outlet pipe 16, and then the flocculant flows out through the multiple liquid outlets 17, and is continuously thrown upwards following the up and down rotation of the spoiler 5, so that the flocculant is initially mixed with the tailings water, and as the two spoilers The continuous rotation of 5 increases the time for the tailings water to fall into the body 1, further increases the initial mixing degree of the flocculant with the tailings water, accelerates the subsequent sedimentation of the tailings water, and avoids the prior art practice of adding the flocculant to the surface of the tailings water at one time, resulting in the flocculant needing to enter the bottom of the tailings water from the upper surface of the tailings water during the mixing process of the flocculant and the tailings water, prolonging the mixing time of the flocculant and the tailings water, reducing the sedimentation rate of the tailings water, and this method can easily lead to uneven distribution of the flocculant, resulting in uneven sedimentation inside the tailings water.

[0028] A plurality of vertical rods 21 are rotatably connected to the top array in the pump liquid chamber 13, and a plurality of first descending aid plates 22 are fixedly connected to the side walls of the plurality of vertical rods 21. A plurality of gears 23 are fixedly connected to the side walls of the plurality of vertical rods 21 located in the pump liquid chamber 13, and a plurality of tooth plates 24 are fixedly connected to the side walls of the slide plate 11 near the gears 23. The tooth plates 24 are meshed with the side walls of the plurality of gears 23 corresponding to the tooth plates 24 (such as Figure 6 as shown).

[0029] An oil pumping mechanism is provided on the fixed frame 4, and the oil pumping mechanism includes two oil pumping frames 25 fixedly connected to the side walls of the fixed frame 4. Hydraulic oil is provided in the oil pumping frames 25. The inner walls of the two oil pumping frames 25 are sealed and slidably connected with a second T-shaped plate 26. The side wall of the second T-shaped plate 26 located outside the oil pumping frame 25 is rotatably connected to the lower end of the spoiler 5 adjacent to it through a fifth plate 28. The top of the oil pumping frame 25 is connected to the bottom of the oil pumping chamber 12 adjacent to it through a connecting pipe 27.

[0030] When the two spoilers 5 rotate up and down, the two spoilers 5 drive the second T-shaped plate 26 to slide back and forth on the inner wall of the oil pump frame 25 through the fifth plate 28, so that the space in the oil pump frame 25 intermittently increases or decreases. At this time, the hydraulic oil will flow back and forth in the oil pump frame 25 and the oil pump cavity 12 through the connecting pipe 27, so that the slide plate 11 slides back and forth on the inner wall of the strip cavity 6. At this time, the multiple tooth plates 24 will drive the multiple vertical rods 21 to rotate through the multiple gears 23, and drive the multiple first descending aid plates 22 to rotate, thereby further accelerating the sedimentation of the tailings water.

[0031] The lower end of the fixed frame 4 is rotatably connected to a threaded cylinder 29, and the side wall of the threaded cylinder 29 is fixedly connected to a plurality of second landing aid plates 30. The lower end of the electric push rod 9 is fixedly connected to a rifle rod 31 (such as Figure 3As shown, the side wall of the rifle rod 31 is threadedly connected to the inner wall of the threaded tube 29 (as shown in FIG. Figure 3 and Figure 4 as shown).

[0032] When the electric push rod 9 is continuously extended and retracted, it will drive the rifle rod 31 to move up and down, and then drive the threaded barrel 29 to continuously rotate, so that the threaded barrel 29 drives the multiple second lowering plates 30 to rotate, so that the flocculant and tailings water are evenly mixed, and the sedimentation of the tailings water is accelerated.

[0033] The second landing aid plate 30 has grooves 32 at the upper and lower ends, and the inner wall of the groove 32 is sealed and slidably connected with a partition 33. The side wall of the partition 33 is elastically connected to the inner wall of the groove 32 through a plurality of magnetic springs 34, and the plurality of magnetic springs 34 are electrically connected to an external control mechanism.

[0034] It should be noted that after the magnetic spring 34 is energized, due to electromagnetic induction, the magnetic spring 34 interacts with the current in the external magnetic field to generate pulling forces of different sizes to control the tensile deformation and movement state of the magnetic spring 34. Furthermore, during the continuous extension and retraction of the electric push rod 9, the external control mechanism controls the multiple magnetic springs 34 to be energized and retracted, so that the partition 33 retracts into the groove 32, thereby accelerating the uniform mixing of the flocculant and the tailings water. When the electric push rod 9 stops extending and retracting, it indicates that the uniform mixing of the flocculant and the tailings water is completed, and the tailings water can be waited for to settle. At this time, the external control mechanism controls the multiple magnetic springs 34 to be de-energized and extended, so that the partition 33 is moved out of the groove 32, and at this time, the side walls of the two adjacent partitions 33 above and below are close to each other, which hinders the flow of the tailings water, stops the flow of the tailings water as soon as possible, and accelerates the static sedimentation of the tailings water.

[0035] When treating tailings water, the tailings water is added into the housing 2 through the two water inlets 3, and the tailings water will directly impact on the two spoilers 5. At this time, the electric push rod 9 is adjusted to continuously extend and retract. At this time, the electric push rod 9 will drive the two spoilers 5 to rotate up and down through the two third plates 10, the two first plates 7 and the two second plates 8, and the tailings water impacting on the two spoilers 5 will be continuously thrown upwards; When the two first plates 7 slide back and forth, the two fourth plates 20 and the two first T-shaped plates 15 will slide back and forth on the inner walls of the two pump liquid frames 14, so that the space in the two pump liquid frames 14 is intermittently increased or decreased. At this time, the two pump liquid frames 14 can squeeze the flocculant in the liquid storage frame 18 into the pump liquid cavity 13 through the one-way suction pipe 19 and the one-way liquid outlet pipe 16, and then the flocculant flows out through the multiple liquid outlets 17, and is continuously thrown upward following the up and down rotation of the spoiler 5, so that the flocculant is initially mixed with the tailings water, and as the two spoilers 5 continue to rotate, the time for the tailings water to fall into the body 1 is increased, further increasing the initial mixing degree of the flocculant with the tailings water, and accelerating the subsequent sedimentation of the tailings water; When the two spoilers 5 rotate up and down, the two spoilers 5 drive the second T-shaped plate 26 to slide back and forth on the inner wall of the oil pump frame 25 through the fifth plate 28, so that the space in the oil pump frame 25 is intermittently increased or decreased. At this time, the hydraulic oil will flow back and forth in the oil pump frame 25 and the oil pump cavity 12 through the connecting pipe 27, so that the slide plate 11 slides back and forth on the inner wall of the strip cavity 6. At this time, the multiple tooth plates 24 will drive the multiple vertical rods 21 to rotate through the multiple gears 23, and drive the multiple first descending plates 22 to rotate, so as to further accelerate the sedimentation of the tailings water; Subsequently, the initially mixed flocculant and tailings water enter the body 1 for storage. At this time, the electric push rod 9 continuously extends and retracts to drive the rifle rod 31 to move up and down, thereby driving the threaded barrel 29 to continuously rotate, so that the threaded barrel 29 drives the plurality of second descending aid plates 30 to rotate, so that the flocculant and tailings water are evenly mixed, and the settling of the tailings water is accelerated. And when the electric push rod 9 is continuously extending and retracting, the external control mechanism controls the multiple magnetic springs 34 to be energized and retracted, so that the partition 33 is retracted into the groove 32, accelerating the uniform mixing of the flocculant and the tailings water. When the electric push rod 9 stops extending and retracting, it means that the uniform mixing of the flocculant and the tailings water is completed, and the tailings water can be waited for to settle. At this time, the external control mechanism controls the multiple magnetic springs 34 to be de-energized and extended, so that the partition 33 is moved out of the groove 32, and at this time, the side walls of the two adjacent partitions 33 above and below are fitted to each other (such as Fig. 9 As shown in the figure), the flow of tailings water is hindered, so that the tailings water stops flowing as soon as possible, thereby accelerating the static sedimentation of the tailings water; After the tailings water settles, the staff can pump out the settled water in the machine body 1 through the pumping pipe 35 , and finally the sediment in the machine body 1 can be discharged through the sewage pipe 36 .

[0036] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
