Description

Technical Field

[0001] This utility model relates to the field of coarse coal slime separation technology, specifically a coarse coal slime secondary separator that prevents sedimentation. Background Technology

[0002] Traditional thickening bed separators often suffer from insufficient separation of low-density materials when the feed concentration fluctuates or the particle distribution is uneven, resulting in the sedimentation of some materials with high-density materials to the bottom without proper separation. This leads to a high content of mismatched substances in the tailings. Existing thickening bed separators mostly adopt a combination structure of cylindrical and conical cylinders. The feed material is usually discharged directly as middlings to the downstream coal slime screen, still containing a significant amount of unrecovered clean coal, which makes it difficult to meet the actual requirements for efficient and stable separation.

[0003] To overcome the above-mentioned defects, the prior art (Chinese patent publication number: CN218573902U, publication date: 2023-03-07) discloses a coal slime separator that prevents material accumulation, including a cylindrical cylinder, a conical cylinder, and a water supply cylinder. The lower end of the cylindrical cylinder is connected to the conical cylinder, and the water supply cylinder is wrapped around the outside of the conical cylinder. The conical cylinder is provided with water distribution holes that connect the water supply cylinder and the inner cavity of the conical cylinder. The water distribution holes are characterized by being divided into vertical holes and inclined holes. Inclined holes are arranged in the circumferential direction at the upper end of the conical cylinder, and the inclined holes are inclined towards the upper middle part of the conical cylinder. Vertical holes are arranged in the circumferential direction at the lower end of the conical cylinder. The combination of inclined holes and vertical holes avoids material accumulation at the upper part of the conical cylinder and also allows the rising water flow to form an interfering bed with the incoming material. It has the advantages of simple structure, good separation effect, good operation effect, and less water waste.

[0004] However, while the above structure can solve the above problems, when the coarse coal slime is deposited at the bottom of the equipment and needs to be mixed efficiently to achieve secondary separation, the existing equipment has limited agitation and mixing capacity, which makes it difficult to fully mix the coarse coal slime with high density; and in the output stage, a large number of coal slime particles are often mixed in the liquid, the output pipeline is prone to blockage, the equipment has low conveying efficiency, unstable operation, and a large amount of maintenance work. Utility Model Content

[0005] The purpose of this invention is to provide a secondary separator for coarse coal slime that prevents sedimentation, in order to solve the technical problems of low sediment mixing efficiency, insufficient mixing of heavy coal slime, and easy blockage during output and transportation in the existing coarse coal slime separation process.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a secondary separator for coarse coal slime that prevents sedimentation, comprising a sedimentation processing barrel, a vertical limiting frame installed inside the sedimentation processing barrel, a flushing nozzle installed inside the sedimentation processing barrel, and the flushing nozzle having a conical flared nozzle inner cavity design, a high-precision concentration sensor installed at the bottom of the barrel for detecting the sediment concentration, and a resisting mixing mechanism for sliding a mixing swing plate up and down inside the vertical limiting frame.

[0007] Furthermore, the meshing and fitting mechanism includes a through-flow block, which is fixedly installed at the output end of the lower open tube. Connecting output tubes are installed at the openings on the left and right sides of the through-flow block, and a mating protrusion is installed at the output end of the rotary motor.

[0008] Furthermore, the outer surface of the mating protrusion is mated and fitted with the interior of the lower opening tube, and a lower fixing gear is installed at the end of the mating protrusion. A stable rotating frame is installed on the inner surface of the through flow block, and an impurity running-in rod is installed inside the stable rotating frame.

[0009] Furthermore, a downward pressing contact spring is installed on the top of the inner surface of the deposition processing tank, and a rotating contact rod is installed on the outer surface of the output end of the rotary motor. A lower driving rod is installed on the lower surface of the end of the contact spring, and the rotation trajectory of the rotating contact rod abuts against the outer surface of the lower driving rod.

[0010] Furthermore, the contact surfaces of the rotating abutment rod and the lower driving rod are both semi-circular, and the top of the hybrid swing plate is fixedly installed on the lower surface of the lower driving rod, the upper surface of the lower driving rod is fixedly installed on the lower end of the pressing abutment spring, and the back of the hybrid swing plate slides vertically along the interior of the vertical limiting frame.

[0011] Furthermore, a rotating mixing plate is installed on the lower outer surface of the output end of the rotary motor, and four sets of pressing contact springs, lower driving rods and mixing swing plates are equally distributed about the center point of the deposition processing tank. The back of the mixing swing plate contacts the inner surface of the vertical limiting frame to form a sliding structure, and the lower end of the pressing contact spring contacts the upper surface of the lower driving rod to form an elastic structure.

[0012] Furthermore, the impurity running-in rod is rotatably installed inside the stable rotating frame, and a side transmission gear is installed at the end of the impurity running-in rod. The lower fixed gear meshes with the side transmission gear, and the end of the impurity running-in rod slides in contact with the inner surface of the connecting output pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: When the deposited coarse coal slime secondary separator needs to be efficiently mixed, the rotating motor drives the rotating mixing plate to initially agitate the deposited coal slime. At the same time, as the rotating contact rod and the lower driving rod contact the mixing swing plate, they will move upward accordingly and be reset during the downward pressing operation of the contact spring. This design improves the mixing efficiency, allows the heavier coarse coal slime to be fully mixed, and improves the uniformity of the separation and the subsequent use effect. Furthermore, when the docking protrusion rotates, the lower fixed gear drives the impurity grinding rod to rotate synchronously through the meshing motion with the side transmission gear. The coal slurry will be ground and crushed through the mutual contact and sliding between the impurity grinding rod and the connecting output pipe. This design prevents the connecting output pipe from accumulating and clogging, thereby improving the discharge efficiency and smoothness of the equipment, and thus reducing the maintenance frequency and repair costs. Furthermore, the interior of the lower open pipe and the exterior of the mating protrusion fit together, enhancing the sealing of the internal structure of the equipment. At the same time, the flushing nozzles designed inside the deposition processing tank can efficiently flush the coal sludge inside the equipment, which helps to improve the cleaning efficiency of the equipment.

[0016] 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.

[0017] Example 1: Please refer to Figure 1 , Figure 2 and Figure 3 The present invention provides the following technical solution: a coarse coal slime secondary separator for preventing deposition, comprising a deposition processing barrel 1, a vertical limiting frame 12 installed inside the deposition processing barrel 1, a flushing nozzle 6 installed inside the deposition processing barrel 1, and the nozzle cavity of the flushing nozzle 6 having a conical flare, a high-precision concentration sensor installed at the bottom of the deposition processing barrel 1 for detecting the concentration of the deposition layer, and a resisting mixing mechanism for sliding the mixing swing plate 10 up and down inside the vertical limiting frame 12.

[0018] like Figure 1 , Figure 2 and Figure 3 The technical solution shown addresses the problem of insufficient mixing efficiency and difficulty in fully mixing heavier coal slime during the agitation process after sedimentation, thus affecting processing quality and subsequent use. This utility model discloses the following: a downward-pressing contact spring 7 is installed on the top of the inner surface of the sedimentation processing tank 1, and a rotating contact rod 8 is installed on the outer surface of the output end of the rotary motor 2. A lower driving rod 9 is installed on the lower surface of the end of the downward-pressing contact spring 7, and the rotation trajectory of the rotating contact rod 8 contacts the outer surface of the lower driving rod 9. The contact surfaces of the rotating contact rod 8 and the lower driving rod 9 are both semi-circular. The top of the mixing swing plate 10 is fixedly installed on the lower surface of the lower driving rod 9. Figure 3 As shown, the upper surface of the lower drive rod 9 is fixedly installed at the lower end of the pressing contact spring 7, and the back of the mixing swing plate 10 slides vertically along the interior of the vertical limiting frame 12. The lower outer surface of the output end of the rotary motor 2 is equipped with a rotating mixing plate 11, and the pressing contact spring 7, the lower drive rod 9 and the mixing swing plate 10 are equally installed in four groups about the center point of the deposition processing tank 1. The back of the mixing swing plate 10 contacts the inner surface of the vertical limiting frame 12 to form a sliding structure, and the lower end of the pressing contact spring 7 contacts the upper surface of the lower drive rod 9 to form an elastic structure.

[0019] When it is necessary to perform a rotary mixing operation on the deposited coarse coal slime, the rotary motor 2 fixedly installed at the top of the deposition processing tank 1 is directly started. At this time, the rotary mixing plate 11 fixedly installed at the output end of the rotary motor 2 will be driven to rotate stably, so that the coal slime deposited at the bottom of the deposition processing tank 1 will be mixed. At the same time, the rotation of the rotary motor 2 will synchronously drive the rotary abutment rod 8. During the rotation of the rotary abutment rod 8, it will abut against the lower driving rod 9. Since the contact surfaces of the rotary abutment rod 8 and the lower driving rod 9 are both semi-circular, and the lower driving rod 9 is slidably installed on the inner bottom surface of the deposition processing tank 1, the lower driving rod 9 will move upward synchronously with the abutment. The movement of the lower driving rod 9 will compress and contract the downward abutment spring 7 fixedly installed at the top. Figure 3 As shown, since the downward pressing contact spring 7 is fixedly installed on the inner top surface of the deposition processing tank 1, the downward pressing contact spring 7 will generate vertical contraction. At this time, the upward movement of the lower end driving rod 9 will synchronously move the mixing swing plate 10 fixedly installed on the lower surface. The mixing swing plate 10 will slide vertically along the corresponding position of the vertical limit frame 12 installed inside the deposition processing tank 1. After the rotating contact rod 8 disengages from the lower end driving rod 9, the downward pressing contact spring 7 will release its elasticity and drive the mixing swing plate 10 to reset again. During this process, the mixing swing plate 10 will efficiently mix the liquid and coal slime.

[0020] Example 2: Figure 4 , Figure 5 and Figure 6 The technical solution shown addresses the problem of coal slurry accumulation and blockage in pipelines during output operations, caused by the presence of such slurry within the liquid. It discloses a meshing and engaging mechanism comprising a through-flow block 4, fixedly installed at the output end of the lower open pipe 3. Connecting output pipes 18 are installed at the openings on both sides of the through-flow block 4. A mating protrusion 13 is installed at the output end of the rotary motor 2, with its outer surface mating against the interior of the lower open pipe 3. Figure 4 As shown, a lower fixed gear 15 is installed at the end of the mating protrusion 13, a stable rotating frame 16 is installed through the inner surface of the flow block 4, and an impurity running-in rod 14 is installed inside the stable rotating frame 16. The impurity running-in rod 14 is rotatably installed inside the stable rotating frame 16, and a side transmission gear 17 is installed at the end of the impurity running-in rod 14. The lower fixed gear 15 and the side transmission gear 17 mesh with each other, and the end of the impurity running-in rod 14 slides against the inner surface of the connecting output pipe 18.

[0021] When the rotary motor 2 rotates, the mating protrusion 13 fixedly installed at the output end of the rotary motor 2 will be driven to rotate synchronously. At this time, the mating protrusion 13 will rotate stably and limit its movement along the lower opening tube 3 fixed at the opening of the deposition processing tank 1. While the mating protrusion 13 is rotating, the lower fixed gear 15 fixedly installed on the lower surface will rotate synchronously. When the lower fixed gear 15 rotates, it will mesh with the side transmission gear 17 that is in contact with the outer surface and drive it. Figure 5 As shown, since the impurity grinding rod 14 is fixedly installed on the side of the side transmission gear 17, the impurity grinding rod 14 will rotate synchronously. At this time, the impurity grinding rod 14 will rotate in a limited circumferential manner within the stable rotating frame 16 fixedly installed inside the through-flow block 4. The rotation of the impurity grinding rod 14 will continuously fit and rotate within the connecting output pipe 18 designed to pass through the left and right sides of the through-flow block 4. During this process, the impurity grinding rod 14 will grind and crush the coarse coal slime, so that no blockage will occur inside the equipment. The discharge pump 5 will assist the connecting output pipe 18 to output efficiently.

[0022] Example 3: Figure 3 The technical solution shown discloses the following to address the problems of poor mixing effect and significant deposition risk in existing designs: a deposition processing tank 1, a vertical limiting frame 12 installed inside the deposition processing tank 1, a rinsing nozzle 6 installed inside the deposition processing tank 1, and the nozzle cavity of the rinsing nozzle 6 having a conical flare, a high-precision concentration sensor installed at the bottom of the deposition processing tank 1 for detecting the deposition layer concentration, and a resisting mixing mechanism for sliding the mixing swing plate 10 up and down inside the vertical limiting frame 12.

[0023] During the mixing and discharge process, the inner cavity of the flushing nozzle 6 adopts a conical flare design. This structure allows the water flow to form a large spray angle when sprayed, resulting in a diffused distribution of the liquid within the deposition tank 1. This enables efficient cleaning of the interior of the deposition tank 1. Furthermore, the conical flare design helps to slow down changes in liquid flow rate, reducing particle aggregation and retention within the nozzle cavity, and lowering the risk of clogging the flushing nozzle 6. Simultaneously, a high-precision concentration sensor is designed at the bottom of the deposition tank 1 to detect the concentration of the deposited layer during the mixing process. The sensor monitors changes in the concentration of the deposited layer using ultrasonic waves or differential pressure principles. When the concentration value increases and the risk of deposition increases, the rotation speed can be adjusted to keep the material loose. According to the existing technology, the concentration sensor is directly embedded in the core area of ​​the fluidized bed layer at the bottom of the deposition processing tank 1 of the anti-deposition coarse coal slime secondary separator, 0-100mm from the bottom plate. It adopts a submerged probe design and detects the change in bed concentration by measuring the pressure difference between two points with a fixed height difference. At the same time, it combines the method of high-frequency sound waves penetrating the medium to judge the local particle concentration state. During this process, local floc deposition can be captured so as to carry out corresponding manual rotation speed adjustment (the technical solution here is the existing technology and is used to illustrate the specific operation mode).
