Description

Technical Field

[0001] The present invention relates to the technical field of tailings water treatment, and particularly relates to a tailings thickener with a structure for assisting sedimentation. Background Art

[0002] Tailings water refers to the wastewater containing a large amount of mineral suspensions and dissolved substances generated after the ore undergoes physical and chemical treatment during the ore dressing process. In the prior art, a thickener is generally used to treat tailings water.

[0003] In the patent "A Flocculant Adding Device for a Deep Cone Thickener" with the application number "202323424976.5", in this solution, the flocculant storage tank is arranged in a fitting manner with the support frame, and the flocculant storage tank forms a communication structure with the upper cover through a connecting pipe. When the adjusting component is opened, the flocculant can be controllably discharged into the fixedly installed box. However, this solution still has certain defects:

[0004] This solution adds the flocculant 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 contacts the tailings water, that is, during the mixing process of the flocculant and the tailings water, the flocculant needs to enter from the upper surface of the tailings water to the bottom of the tailings water in order to make all of the tailings water contact the flocculant. However, this method prolongs the mixing time of the flocculant and the tailings water, reduces the sedimentation speed of the tailings water, and this method is likely to cause uneven distribution of the flocculant, resulting in uneven sedimentation inside the tailings water. Summary of the Invention

[0019] Compared with the existing technology, the advantages of the present invention are as follows:

[0020] 1. A descending aid mechanism and a pump liquid mechanism are provided. When the two first plates slide back and forth, at this time the flocculant flows out through a plurality of liquid outlets, and is continuously thrown upwards following the up and down rotation of the spoiler plate, so that the flocculant is initially mixed with the tailings water. And as the two spoiler plates rotate continuously, the time for the tailings water to fall into the machine body increases, further increasing the initial mixing degree of the flocculant and the tailings water, accelerating the subsequent sedimentation of the tailings water, and avoiding the situation in the prior art where the flocculant is added 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 speed of the tailings water, and this method is likely to cause uneven distribution of the flocculant, resulting in uneven sedimentation inside the tailings water.

[0021] 2. A first descending aid plate and a pump oil mechanism are provided. When the two spoiler plates rotate up and down, both spoiler plates drive the second T-shaped plate to slide back and forth on the inner wall of the pump oil frame through the fifth plate, so that the space inside the pump oil frame intermittently increases or decreases. At this time, the hydraulic oil will flow back and forth between the pump oil frame and the pump oil cavity through the connecting pipe, causing the slide plate to slide back and forth on the inner wall of the strip cavity. At this time, a plurality of toothed plates will drive a plurality of vertical rods to rotate through a plurality of gears, driving a plurality of first descending aid plates to rotate, further accelerating the sedimentation of the tailings water.

[0022] 3. A partition plate and a magnetic spring are provided. When the electric push rod stops telescoping, it indicates that the uniform mixing of the flocculant and the tailings water is completed. At this time, wait for the tailings water to settle. At this time, the external control mechanism controls the plurality of magnetic springs to be powered off and extended, so that the partition plate moves out of the groove, and at this time, the side walls of the two adjacent partition plates facing each other are in contact, hindering the flow of the tailings water, so that the tailings water stops flowing as soon as possible, accelerating the static sedimentation of the tailings water.

Specific embodiments

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Referring to Figure 1- Figure 9 , a tailings thickener with a landing assistance structure, comprising a machine body 1, a shell 2 is fixedly connected to the upper end of the machine body 1, two water inlets 3 are opened at the upper end of the shell 2, a water extraction pipe 35 is slidably connected to the inner top of the machine body 1, which can extract the settled water in the machine body 1, a sewage discharge pipe 36 is fixedly connected to the lower part of the inner wall of the machine body 1, a valve is installed in the sewage discharge pipe 36, and a bottom cover 37 is fixedly installed at the lower end of the machine body 1 through a plurality of bolts.

[0035] The landing assistance mechanism, the landing assistance mechanism includes a fixed frame 4 fixedly connected to the inner top of the shell 2, spoiler plates 5 are rotatably connected to the mutually remote side walls of the fixed frame 4 through rotating shafts, the inner walls of the fixed frame 4 below the two spoiler plates 5 are all slidably connected through the first plates 7, and the side walls of the first plates 7 outside the fixed frame 4 are rotatably connected to the lower ends of the spoiler plates 5 close to them through the second plates 8, an electric push rod 9 is fixedly connected to the upper end of the shell 2, and the side wall of the movable shaft of the electric push rod 9 is rotatably connected to the upper ends of the two first plates 7 through two third plates 10 respectively. A strip-shaped cavity 6 is opened in the spoiler plate 5, a slide plate 11 is hermetically slidably connected to the inner wall of the strip-shaped cavity 6, and the slide plate 11 divides the strip-shaped cavity 6 into a pump oil cavity 12 and a pump liquid cavity 13 (as Figure 6 shown), and a plurality of liquid outlets 17 are opened at the inner top of the pump liquid cavity 13 away from the slide plate 11.

[0036] The 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, adjust the electric push rod 9 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 continuously throw up the tailings water impacting on the two spoiler plates 5.

[0037] A pump liquid mechanism is arranged on the fixed frame 4, the pump liquid mechanism includes two pump liquid frames 14 fixedly connected to the lower end of the fixed frame 4, the inner walls of the two pump liquid frames 14 are hermetically slidably connected with first T-shaped plates 15, the lower ends of the two first plates 7 are fixedly connected with fourth plates 20, and the fourth plates 20 are fixedly connected with the side walls of the first T-shaped plates 15 close to them. The inner bottom of the pump liquid frame 14 is communicated with the inner bottom of the pump liquid cavity 13 through a one-way liquid outlet pipe 16.

[0038] A liquid storage frame 18 is fixedly connected to the side wall of the shell 2, and the inner walls of the two pump liquid frames 14 are communicated with the inner wall of the liquid storage frame 18 through one-way liquid suction pipes 19 (as Figure 5 shown), and a flocculant is arranged in the liquid storage frame 18.

[0039] A one-way valve that only allows the flocculant to enter the pump liquid cavity 13 from the pump liquid frame 14 is installed in the one-way liquid outlet pipe 16, and a one-way valve that only allows the flocculant to enter the pump liquid frame 14 from the liquid storage frame 18 is installed in the one-way liquid suction pipe 19.

[0040] When the two first plates 7 slide back and forth, they will slide back and forth on the inner walls of the two pump liquid frames 14 through the two fourth plates 20 and the two first T-shaped plates 15, causing the spaces in the two pump liquid frames 14 to increase or decrease intermittently. At this time, both of 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 liquid suction pipe 19 and the one-way liquid discharge pipe 16. Subsequently, the flocculant flows out through multiple liquid discharge ports 17 and is continuously thrown upward following the up and down rotation of the spoiler plate 5, enabling the flocculant to be initially mixed with the tailings water. And with the continuous rotation of the two spoiler plates 5, the time for the tailings water to fall into the machine body 1 increases, further increasing the initial mixing degree of the flocculant and the tailings water, accelerating the subsequent sedimentation of the tailings water, and avoiding the situation in the prior art where the flocculant is added to the surface of the tailings water at one time, resulting in the flocculant needing to enter from the upper surface of the tailings water to the bottom 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 speed of the tailings water, and this method is prone to uneven distribution of the flocculant, leading to uneven sedimentation inside the tailings water.

[0041] A plurality of vertical rods 21 are rotatably connected to the top of the inner part of the pump liquid cavity 13 in an array. A plurality of first descending 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 inside the pump liquid cavity 13. A plurality of toothed plates 24 are fixedly connected to the side wall of the sliding plate 11 close to the gear 23, and the toothed plates 24 are meshed with the side walls of the corresponding plurality of gears 23 (as Figure 6 shown).

[0042] A pump oil mechanism is provided on the fixed frame 4. The pump oil mechanism includes two pump oil frames 25 fixedly connected to the side wall of the fixed frame 4. Hydraulic oil is provided inside the pump oil frames 25. The inner walls of the two pump oil frames 25 are hermetically slidably connected with second T-shaped plates 26. The side wall of the second T-shaped plate 26 located outside the pump oil frame 25 is rotatably connected to the lower end of the spoiler plate 5 close to it through a fifth plate 28. The top of the pump oil frame 25 is communicated with the bottom of the pump oil cavity 12 close to it through a connecting pipe 27.

[0043] When the two spoiler plates 5 rotate up and down, both of the two spoiler plates 5 drive the second T-shaped plates 26 to slide back and forth on the inner walls of the pump oil frames 25 through the fifth plates 28, causing the spaces in the pump oil frames 25 to increase or decrease intermittently. At this time, the hydraulic oil will flow back and forth between the pump oil frames 25 and the pump oil cavity 12 through the connecting pipe 27, causing the sliding plate 11 to slide back and forth on the inner wall of the strip-shaped cavity 6. At this time, the plurality of toothed plates 24 will drive the plurality of vertical rods 21 to rotate through the plurality of gears 23, driving the plurality of first descending plates 22 to rotate, further accelerating the sedimentation of the tailings water.

[0044] The lower end of the fixed frame 4 is rotatably connected with a threaded cylinder 29. A plurality of second descending plates 30 are fixedly connected to the side wall of the threaded cylinder 29. The lower end of the electric push rod 9 is fixedly connected with a rifled rod 31 (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).

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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;

[0049] 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;

[0050] 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;

[0051] 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.

[0052] 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 Figure 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;

[0053] 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 .

[0054] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, making equivalent replacements or changes, shall be covered by the protection scope of the present invention.
