Description

Technical Field

[0001] The invention relates to the field of sedimentation screening, and in particular to a screening settler. Background Art

[0002] Screening settler is a separation equipment widely used in various mineral processing processes. After the slurry enters the screening settler, the solid particles gradually sink under the action of gravity. At the same time, because the particles in the fluid are affected by the surrounding flow field, the sedimentation of the particles interferes with each other, resulting in a decrease in the sedimentation rate of the particles, thereby achieving the separation and classification of different particles.

[0003] Since the separation and classification of particles is achieved through the combined action of flow field and gravity, it is inevitable that the separation and classification accuracy of the screening and settling device is low during use. Currently, the commonly used screening and settling devices are generally used in the initial separation stage of mineral processing, but in the separation scenarios that require relatively high precision, the general screening and settling devices are difficult to meet the use requirements.

[0038] The features and exemplary embodiments of various aspects of the present invention will be described in detail below. In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only configured to explain the present invention and are not configured to limit the present invention. For those skilled in the art, the present invention can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present invention by illustrating examples of the present invention.

[0039] The directional words appearing in the following description are all directions shown in the figures, and do not limit the specific structure of the present invention. In the description of the present invention, it should also be noted that, unless otherwise clearly specified and limited, the terms "installation, connection" should be understood in a broad sense, for example, it can be a fixed connection, or a detachable connection or an integral connection; it can be directly connected or indirectly connected. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0040] The embodiment of the present invention provides a screening settler, see Figures 1 to 8 The screening settler includes an inner cylinder 101, the inner bottom of the inner cylinder 101 is in an inverted cone shape, a diverter mechanism 200 is installed at the bottom of the inner cylinder 101, the diverter mechanism 200 is used to supply water into the inner cylinder 101, and the water flow direction is from bottom to top along the height direction of the inner cylinder 101.

[0041] The upper inner part of the inner tube 101 is in the shape of a square column, and a plurality of sedimentation boxes 102 and separation boxes 104 are fixed on the outer side of the inner tube 101. The sedimentation boxes 102 and the separation boxes 104 are arranged at intervals. The sedimentation boxes 102 are located at the side of the inner tube 101, and the separation boxes 104 are located at the corner of the inner tube 101. Discharge valves 105 are fixedly installed at the bottom of the plurality of sedimentation boxes 102 and the separation boxes 104 for unloading the materials in the sedimentation boxes 102 and the separation boxes 104.

[0042] The top of the settling box 102 is fixedly connected to a drainage pipe 103, and the drainage pipe 103 is used to discharge the water flow at the top of the settling box 102 to the outside. A plurality of mounting frames 106 are fixedly installed on the outside of the settling box 102 to facilitate the installation of the screening settler.

[0043] A feeding mechanism 400 is coaxially fixedly installed on the top of the inner cylinder 101 . The feeding mechanism 400 is used to evenly add and distribute the material in the inner cylinder 101 , so as to achieve even distribution of the material particles in the flow field and facilitate suspension of the material particles in the inner cylinder 101 .

[0044] On the partition between the inner tube 101 and the sedimentation box 102, a plurality of first channels 111 are evenly opened along the height direction. The first channels 111 are connected to the inside of a baffle ring 112. The baffle ring 112 is installed inside the sedimentation box 102. The cross-sectional shape of the baffle ring 112 is a whistle shape, that is, the side close to the first channel 111 is tangent to the first channel 111 in the horizontal direction, and the side away from the first channel 111 is in the shape of a volute.

[0045] A plurality of sieve holes 113 are evenly arranged on the side and bottom of the baffle ring 112 for filtering materials of different particle sizes inside the baffle ring 112. A spoiler tongue 114 is also fixedly installed inside the baffle ring 112. The upper surface of the spoiler tongue 114 is flush with the lower surface of the first channel 111, and the lower surface of the spoiler tongue 114 is arc-shaped and tangent to the inner surface of the baffle ring 112.

[0046] The structure of the baffle ring 112 in this embodiment allows the mixture of material and water in the inner cylinder 101 to enter the baffle ring 112 through the first channel 111, and then the material with a particle size smaller than the sieve hole 113 passes through the sieve hole 113 and enters the sedimentation box 102 with the water flow, thereby achieving the first separation of the material.

[0047] The materials entering the sedimentation box 102 will have their water flow velocity significantly slowed down. The materials with higher density will gradually settle at the bottom of the sedimentation box 102 due to the reduced impact force of the water flow, while the materials with lower density will be discharged outward from the drainage pipe 103 at the top of the sedimentation box 102 along with the water flow of the sedimentation box 102, thus achieving the second separation of the materials.

[0048] In addition, the material remaining in the baffle ring 112 will rotate and flow along the axial direction of the baffle ring 112 at the bottom of the baffle ring 112 under the impact of the water flow continuously flowing into the baffle ring 112 from the first channel 111, and the material remaining in the baffle ring 112 will be thoroughly screened, so that the material with a particle size smaller than the sieve hole 113 has sufficient opportunity to pass through the sieve hole 113 and enter the sedimentation box 102, thereby achieving sufficient screening and separation of the material.

[0049] The first channel 111 and the baffle ring 112 have the same contour direction, and both are symmetrical structures with a high middle and low ends. The two end surfaces of the baffle ring 112 are respectively connected to the separation box 104 located on both sides thereof.

[0050] The materials remaining in the baffle ring 112 after multiple rotational flow screenings will move from the middle position to the two end positions of the baffle ring 112 under the combined action of the water flow and its own gravity until they flow into the separation box 104 and are collected.

[0051] Through the above screening process, materials with particle sizes larger than the sieve holes 113 are finally gathered in the separation box 104 for collection; materials with particle sizes smaller than the sieve holes 113 and materials with higher density settle at the bottom of the sedimentation box 102; materials with particle sizes smaller than the sieve holes 113 and materials with lower density are discharged outward along the drainage pipe 103 at the top of the sedimentation box 102, thereby realizing the three-level separation of materials.

[0052] The top of the separation box 104 transports the water inside the separation box 104 to the inner tube 101 through the reflux mechanism 300, and flows from the center position of the inner tube 101 to the surrounding areas, which is used to cooperate with the upward water flow in the inner tube 101, so that the water flow in the inner tube 101 can flow from the middle position to the surrounding areas while flowing upward, so as to facilitate the mixture of water and material in the inner tube 101 to flow into the baffle ring 112 through the first channel 111, so as to realize the screening of the material.

[0053] As a further explanation of the above embodiments, see Figure 6 , Figure 7 The diversion mechanism 200 includes an inlet pipe 201, which is fixedly connected to the water supply pipe and is used to introduce the water flow in the water supply pipe into the inner tube 101. The inlet pipe 201 is fixedly connected to the bottom of the diversion chamber 202. The outer side of the diversion chamber 202 is evenly fixedly connected with a plurality of diversion pipes 204 along the circumferential direction. The diversion pipes 204 are respectively connected to a plurality of diversion grooves 205 arranged at the bottom of the inner tube 101 and evenly distributed in an annular shape.

[0054] In addition, an inverted cone-shaped guide seat 203 is coaxially arranged inside the diverter chamber 202, and the guide seat 203 is fixed to the bottom of the inner cylinder 101, so that the water flow entering the diverter chamber 202 through the inlet pipe 201 can be evenly and smoothly distributed in the diverter pipe 204 outside the diverter chamber 202 under the diversion effect of the guide seat 203, ensuring that the water flow flowing from the diverter groove 205 into the inner cylinder 101 can be evenly distributed in the circumferential direction of the inner cylinder 101.

[0055] The above structure enables water to flow from bottom to top in the inner cylinder 101, so that the water can drive materials of different particle sizes, shapes and densities in the inner cylinder 101 to be suspended, making it convenient to classify materials with different suspension degrees.

[0056] As a further explanation of the above embodiments, see Figure 3 , Figure 6 , Figure 7The reflux mechanism 300 includes a reflux pipe 301, a first end of the reflux pipe 301 is fixedly connected to the top of the separation box 104, a pump body 302 is installed on the reflux pipe 301, a second end of the reflux pipe 301 is fixedly connected to the top of the diversion tube 303, the diversion tube 303 is coaxially arranged inside the inner tube 101, and the diversion tube 303 is installed on the outside of the diversion mechanism 200, and the diversion tube 303 is evenly opened with a plurality of slots 304 along the height direction.

[0057] Among them, the slots 304 are evenly opened along the circumference of the diverter tube 303, and the opening direction is facing the sedimentation box 102. In addition, in the same direction, the number of the slots 304 is equal to the number of the first channels 111. The slots 304 correspond to the first channels 111 one by one, and the horizontal height of a corresponding group of slots 304 is slightly lower than the horizontal height of the first channel 111.

[0058] Since the material in the separation box 104 is the remaining material after screening, its particle size is relatively large, and then it will be deposited at the bottom after entering the separation box 104, so that the water at the top of the separation box 104 will basically not be mixed with materials. At this time, the water at the top of the separation box 104 is transported to the diversion cylinder 303 through the reflux pipe 301 equipped with a pump body 302, and flows horizontally outward through a plurality of slots 304 opened on the diversion cylinder 303. Since the water flow in the inner cylinder 101 flows from bottom to top, under the joint action of the above two water flows, the water flow of the mixed material in the inner cylinder 101 can more easily enter the first channel 111 to complete screening.

[0059] As a further embodiment of the present invention, see Figure 8 The feeding mechanism 400 includes a feeding barrel 401, which is coaxially fixedly installed inside the inner barrel 101. The top side of the feeding barrel 401 is fixedly connected to the bottom of the silo 402. The silo 402 is used to hold the materials to be separated. A motor 403 is fixedly installed on the top of the feeding barrel 401. The output end of the motor 403 passes through the top of the feeding barrel 401 and is coaxially fixed to the screw push rod 404. The screw push rod 404 is rotatably configured inside the feeding barrel 401. The bottom end of the screw push rod 404 is rotatably installed on the base 406, and the base 406 is fixed to the bottom of the inner barrel 101.

[0060] A plurality of push plates 405 are installed along the circumference of the bottom of the spiral push rod 404. The push plates 405 are rotatably arranged in the gap formed by the bottom of the feed barrel 401 and the base 406. Under the driving action of the output end of the motor 403, the material at the bottom of the feed barrel 401 is pushed out from the middle position to the surrounding areas.

[0061] The bottom of the feed barrel 401 is in a trumpet shape, and the outline of the base 406 is in a truncated cone shape. This structure facilitates the push plate 405 to push the material at the bottom of the feed barrel 401 from the center to the periphery.

[0062] The push plate 405 is an arc-shaped plate, so when the output end of the motor 403 drives the push plate 405 to rotate, the material at the bottom of the feed barrel 401 can be smoothly pushed to move outward.

[0063] In addition, in order to coordinate the uniform suspension of the material inside the inner cylinder 101, Figure 7 As shown, a plurality of diverter slots 205 are annularly arranged outside the circumference of the base 406, so that the material pushed out from the side of the base 406 can move smoothly to the top of the inner tube 101 under the impact of the water flow flowing out of the diverter slots 205, thereby achieving suspension of the material.

[0064] According to the embodiments of the present invention as described above, these embodiments do not describe all the details in detail, nor do they limit the invention to the only specific embodiments. Obviously, based on the above description, many modifications and changes can be made. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present invention, so that those skilled in the art can make good use of the present invention and the modified use based on the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
