[0032] The beneficial effect of this embodiment is as follows: the present application provides an arc-shaped material guiding channel on the material feeding well 10, which is different from the prior art in which the material is directly introduced into the material feeding well 10. The material guiding portion 12 buffers the incoming material, so that after the incoming material enters the material guiding portion 12 from the material feeding interface 11, it needs to travel along the arc-shaped channel of the material guiding portion 12 before entering the material discharging portion 13, thereby improving the flow path of the incoming material and the incoming material will impact the arc-shaped path, effectively reducing the kinetic potential energy of the incoming material, reducing the splashing of the material, reducing the impact on the settled material at the bottom of the pool, and reducing the impact on the concentration of the overflow water at the top of the pool, thereby reducing the impact on the existing material in the concentration tank, and also improving the efficiency of material dispersion and fusion, thereby facilitating the improvement of the utilization efficiency of the concentration tank.

[0033] On the basis of the above embodiment, the material guiding portion 12 may be located on the side wall of the material inlet well 10 , and the material discharging portion 13 may be located in the middle of the material inlet well 10 or in the lower part of the material inlet well 10 .

[0034] Example 2

[0035] Preferably, based on Example 1, see Figure 5 , Figure 6 and Figure 7 There are at least two material guide parts 12 extending in different directions. A baffle 14 is provided in the middle of the feed interface 11, and the baffle 14 divides the feed interface 11 into at least two feed channels, each of which is connected to its corresponding material guide part 12.

[0036] The beneficial effect of adopting the preferred scheme in the above embodiment is that at least two feeding channels are provided to divert the feeding material, so that the incoming material is divided into two streams leading to the two material guiding parts 12 by the baffle 14 at the material guiding part 12, and the kinetic potential energy of the incoming material is reduced by the arc-shaped channels of the two material guiding parts 12, thereby reducing the impact of new materials entering the concentration tank on the existing materials in the concentration tank, thereby facilitating the fusion of the materials after entering the concentration tank.

[0037] On the basis of the above embodiment, a triangular diversion area is provided behind the baffle 14 to facilitate diversion of the feed and guide it into the two guide parts 12. The triangular shape has good stability, which is convenient for supporting the baffle 14 and improving the stability of the baffle 14. Specifically, at least one feed interface 11 is provided on the feed well 10. When the required feed speed or feed flow rate is large, multiple feed interfaces 11 can be provided; wherein, the number of guide parts 12 on each feed interface 11 is not limited to two, that is, the number of baffles 14 on the feed interface 11 is not limited to one, and the number of guide parts 12 can be adjusted according to the specific application scenario.

[0038] Example 3

[0039] Preferably, based on Example 2, see Figure 5 , Figure 6 and Figure 7 The feed well 10 is annular, and the two guide parts 12 extend along the annular side wall of the feed well 10, one of the guide parts 12 is bent upward, and the other guide part 12 is bent downward, and the two ends of the guide part 12 respectively penetrate the inner wall and outer wall of the annular structure of the feed well 10, the discharge part 13 is formed in the axial center hole of the feed well 10, and the feed interface 11 is fixed on the outer wall of the feed well 10; the arc of the guide part 12 along the circumference of the feed well 10 is less than π.

[0040] The beneficial effect of adopting the preferred scheme in the above embodiment is that the feed well 10 is annular, the guide part 12 extends along the side wall of the feed well 10 and has an arc-shaped structure, and bending structures are provided on both guide parts 12, so that the length of the arc-shaped channel of the guide part 12 is lengthened, thereby increasing the path for the incoming material to move in the guide part 12, which is beneficial to the reduction of the kinetic potential energy of the incoming material.

[0041] Based on the above embodiments, see Figure 5 , Figure 6 and Figure 7The two guides 12 extend in opposite directions, which can avoid collision and splashing of materials flowing out of the two guides 12 due to overlapping paths, thereby reducing the impact on the sedimentation of materials in the concentration tank. The axial direction of the feed well 10 is located in the vertical direction. The feed well 10 is provided with a plurality of partitions perpendicular to the axial direction or at a certain angle. The two sides of the partitions are respectively fixed to the inner wall and the outer wall of the feed well 10, so as to divide the feed well 10 into a material guide channel and a material guide part 12. The upper and lower side walls of the material guide part 12 are surrounded by the partitions, and the inner and outer side walls of the material guide part 12 are surrounded by the inner wall and the outer wall of the feed well 10.

[0042] Example 4

[0043] Preferably, based on Examples 1-3, see Figure 5 and Figure 6 The feed interface 11 is located at the upper part of the feed well 10 , and the feed interface 11 is connected to a feed pipe 20 , and one end of the feed pipe 20 close to the feed interface 11 has a bending structure.

[0044] The beneficial effect of adopting the preferred scheme in the above embodiment is that the feed interface 11 is located at the upper part of the feed well 10, which is convenient for the setting and extension of the guide part 12 on the side wall of the feed well 10, and is convenient for the connection between the feed pipe 20 and the feed well 10; the feed pipe 20 is provided with a bend, which has a buffering effect on the incoming material and has the effect of reducing the speed of the incoming material, which can effectively reduce the kinetic potential energy of the incoming material, thereby reducing the impact of the incoming material on the separated material in the concentration tank.

[0045] Based on the above embodiments, see Figure 1 and Figure 2 The bending structure of the feed pipe 20 divides the feed pipe 20 into two transverse parts and an oblique part; both ends of the bending structure are connected to the transverse parts, wherein the height of one transverse part close to the feed well 10 is lower than the other, so as to facilitate the movement of the material and also facilitate the material to enter the feed well 10; the middle part of the bending structure is the oblique part, and the two transverse parts are connected by the oblique part. The bending structure has a buffering effect, and the oblique part facilitates the movement of the material and prevents the material from being blocked at the bending part of the feed pipe 20. The feed interface 11 is located on the outer wall of the feed well 10 and is located at the upper part of the feed well 10. The feed interface 11 is used to connect the feed pipe 20 and allow the material to be introduced into the feed well 10.

[0046] Example 5

[0047] Preferably, based on Examples 1-4, see Figure 1 , Figure 2 and Figure 3 , a concentrator is provided, including a feeding structure of the concentrator, and also including a tank body 30 located below the feeding structure, wherein a rake frame 40 is provided in the tank body 30 and is in contact with or close to the bottom of the tank body 30.

[0048] The beneficial effect of adopting the preferred solution in the above embodiment is that the tank body 30 is arranged below the feeding structure, which facilitates the incoming materials to enter the tank body 30, and a rake frame 40 is arranged in the tank body 30 to facilitate the rake frame 40 to rake the bottom sediment.

[0049] Based on the above embodiments, when the feed well 10 introduces the material into the pool body 30, the material can be directly introduced below the liquid surface of the pool body 30, or other methods that can reduce the impact of new materials entering the pool body 30 on the concentration of the upper and lower parts of the existing materials can also be used.

[0050] Example 6

[0051] Preferably, based on Example 5, see Figure 3 The rake frame 40 includes two short rakes 41 and two long rakes 42, and the short rakes 41 and the long rakes 42 are alternately arranged and perpendicular to each other.

[0052] The beneficial effect of adopting the preferred scheme in the above embodiment is that, due to the effect of gravity, there is less sedimentary material in the outer circle of the pool body 30, and more sedimentary material near the middle of the pool body 30. Therefore, the long rake 42 and the short rake 41 are arranged alternately, so that the central part of the pool body 30 with more sedimentary material can be raked more by the rake frame 40, thereby facilitating the discharge of the sedimentary material.

[0053] Based on the above embodiments, see Figure 1 and Figure 2 , the rake frame 40 can be crane-shaped, that is, the short rake 41 and the long rake 42 are crane-like wing structures, and the rake frame 40 is a structure with a smaller root and a pointed tail, which is suitable for movement in the fluid, and is also convenient for rotation in the fluid, and the force is also smaller; the rake frame 40 is a circular tubular structure, and preferably, a hollow tube can be used to make the rake frame 40; the crane-shaped pipe structure has a greater buoyancy in the fluid than the rake frame 40 structure composed of other profiles, and the circular pipe and the crane-shaped wings are conducive to reducing the resistance and drag coefficient when rotating in the fluid, improving the durability of the structure, thereby increasing the service life of the rake frame 40; and the rake frame 40 is made of a round tube, which can make the force surface small, and the force can also be diverted when the wings rotate, thereby reducing the resistance to material sedimentation; therefore, the crane-shaped rake frame 40 raks the fluid settled at the bottom in the fluid, which can avoid agglomeration and deposition, and at the same time push the settled fluid to flow to the discharge port 32.

[0054] Example 7

[0055] Preferably, based on Examples 5-6, see Figure 2 , Figure 3 and Figure 4 A deformable scraper 43 is connected to the bottom of the rake frame 40.

[0056] The beneficial effect of adopting the preferred scheme in the above embodiment is that the scraper 43 is provided to push the material when the rake frame 40 moves, thereby facilitating the gathering and discharge of the material; the scraper 43 is deformable, so that the scraper 43 can produce a certain deformation according to the shape or size of the material, thereby improving the adaptability of the scraper 43, so that the scraper 43 can better push the block material, granular material or sedimentation material to move.

[0057] Based on the above embodiments, see Figure 2 , Figure 3 and Figure 4 The scraper 43 may be a long strip structure, the scraper 43 may be at a certain angle to the rake frame 40, and both ends of the scraper 43 extend out in the width direction of the rake frame 40; multiple scrapers 43 extend out on both sides of the width direction of the rake frame 40, and the scrapers 43 may be arranged equidistantly or in a certain pattern. When the rake frame 40 rotates or moves, the scraper 43 may serve as an auxiliary to the rake frame 40 to drive the material to move, thereby facilitating the stirring of the material deposited at the bottom and facilitating the material to move toward the center of the pool body 30, thereby facilitating the discharge of the deposited material from the discharge portion 13 of the pool body 30.

[0058] Example 8

[0059] Preferably, based on Examples 5-7, see Figure 1 and Figure 2 The pool body 30 is in a cone shape that is larger at the top and smaller at the bottom. The arc surface of the pool body 30 is divided into two connected cone surfaces 31 in the horizontal direction, and the slope of the cone surface 31 near the middle of the pool body 30 is larger.

[0060] The beneficial effect of adopting the preferred solution in the above embodiment is that, see Figure 1 and Figure 2 The conical pool body 30 facilitates the material to settle toward the middle, so as to facilitate the gathering and discharge of the material; the pool body 30 is provided with two conical surfaces 31, and the slopes of the two conical surfaces 31 are different. Since the slope of the conical surface 31 close to the center of the pool body 30 is larger, it is easier for the material to enter the center of the pool body 30 when it settles, thereby facilitating the gathering of the material when it settles, and also facilitating the subsequent discharge of the material.

[0061] On the basis of the above embodiment, when used specifically, the angles between the two sections of the cone 31 and the horizontal plane can be 5° and 11° respectively, wherein the angle between the cone 31 located in the middle of the tank body 30 and the horizontal plane is 11°. The tank body 30 of the present application is relatively lower, and the height of the conventional tank body 30 is more than twice that of the present application. Generally speaking, a taller tank body 30 has better sedimentation and can settle efficiently, but the combination of the two-section cone 31, the feeding structure and the rake 40 of the present application can also achieve the effect of efficient sedimentation, thereby reducing the height of the tank body 30, thereby reducing the construction cost of the tank body 30; but the specific height of the tank body 30 can be adjusted according to the type of fluid being settled and the required sedimentation efficiency.

[0062] Example 9

[0063] Preferably, based on Examples 5-8, see Figure 1 and Figure 2 A discharge port 32 is provided in the middle of the tank body 30 , and the rake frame 40 includes a central rake portion 44 , which extends into the discharge port 32 .

[0064] The beneficial effect of adopting the preferred scheme in the above embodiment is that a discharge port 32 is provided in the middle of the pool body 30 to facilitate the discharge of materials after deposition, and a central rake portion 44 is provided, and the central rake portion 44 extends into the discharge port 32, so that the discharge port 32 can be easily raked using the central rake portion 44 to avoid accumulation and blockage of materials at the discharge port 32, thereby ensuring smooth discharge of materials from the discharge port 32.

[0065] Based on the above embodiments, see Figure 3 A pull rope 50 is also provided between the rake frames 40. The pull rope 50 is connected to the outer end of the short rake 41 and extends to the long rake 42. Both ends of each pull rope 50 are respectively connected to the short rake 41 and the long rake 42. A total of four pull ropes 50 are provided. The four pull ropes 50 form a rectangular frame structure, thereby enhancing the strength and stability of the rake frame 40. When the rake frame 40 moves, the stability of the rake frame 40 is improved and the deformation of the rake frame 40 is reduced.

[0066] Example 10

[0067] Preferably, based on Examples 5-9, see Figure 1 A hydraulic control system 60 is also provided above the feed well 10 . The hydraulic control system 60 is connected to the rake frame 40 through a vertical bracket 70 and is used to control the lifting and rotation of the rake frame 40 .

[0068] The beneficial effect of adopting the preferred scheme in the above embodiment is that a hydraulic control system 60 is set, and the hydraulic control system 60 is used to drive the rake frame 40 to rotate or lift, thereby driving the rake frame 40 to rake the sediment in the pool body 30, avoiding the sediment from agglomerating at the bottom of the pool body 30, facilitating the sediment to move toward the middle of the pool body 30, and facilitating the subsequent discharge of the sediment from the discharge port 32 in the middle of the pool body 30.

[0069] The solution of the utility model is provided with a low tank body 30 structure, which effectively reduces the infrastructure cost; the feed pipe 20 is a progressive type with a center level, and a bend is provided near the feed well 10. The feed well 10 has an arc-shaped guide portion 12, which effectively reduces the kinetic potential energy of the incoming material and reduces the impact of the new material entering on the settled and separated materials in the tank body 30; the rake frame 40 is crane-shaped, which effectively reduces the resistance when moving in the material, increases the life of the rake frame 40, and also reduces the pressure of the power system; an automated hydraulic control system 60 is provided, which can realize network automated intelligent control, reduce operating labor costs, and improve the operating reliability of the concentrator system.

[0070] The method of use is as follows: the material is introduced from the feed pipe 20 and enters the feed well 10 and the tank body 30 in turn. After the material enters the feed well 10, it is first diverted from the feed interface 11 and enters different material guide parts 12, and then the material is introduced into the tank body 30 through the discharge part 13; when the material is in the tank body 30, the hydraulic control system 60 drives the rake frame 40 to move up and down or rotate, thereby raking the material deposited at the bottom of the tank body 30, so as to facilitate the material to gather toward the middle of the tank body 30, and the gathered material is discharged from the discharge port 32 of the tank body 30.
