Abstract
Description
Technical Field
[0001] This utility model relates to the field of mineral processing equipment technology, specifically to a shaking table device and a sorting system. Background Technology
[0002] Shaking table separation is a common gravity separation method widely used in industries such as mining and metallurgy for the effective separation of ores. Traditional shaking table devices typically include two feed hoppers, one for supplying slurry and the other for supplying water to the table. During this process, the ore is washed by water in the feed hopper and flows out as a slurry, then evenly distributed across the table through the feed openings for subsequent separation operations.
[0003] In existing shaking table devices, when the ore is fed, although it flows out as a slurry after being washed by water in the feed box, the ore remains relatively concentrated and does not reach its maximum dispersion when it flows onto the table. This concentrated flow of slurry leads to uneven distribution of the ore on the table, thus affecting the separation effect. To solve this problem, current technology can only change the slurry concentration by adjusting the water supply to achieve uniformity of slurry flow onto the table. However, this adjustment method has certain limitations in practical operation and cannot completely meet the requirement of uniform slurry distribution. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a shaking table device and a sorting system, which solves the problem that the concentrated supply of slurry in existing systems affects the sorting effect.
[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: a shaking table device, including a feeding box, wherein the inside of the feeding box is divided into a first material box and a second material box by a partition, both the first material box and the second material box have feeding openings on their front sides, and a feeding box is provided on the rear side of the first material box. The feeding box is provided with a slurry outlet pipe, and the slurry outlet pipe is inserted into the first material box.
[0006] The first material box is provided with a boss, and a material feeding mechanism is provided above the boss. The material feeding mechanism includes a beam rod arranged along the length direction of the first material box, and a set of paddles that can reciprocate on the beam rod is provided. The set of paddles is located in front of the slurry outlet pipe.
[0007] Preferably, the slurry outlet pipe is located above the boss.

[0018] Beneficial effects
[0019] By using the shaking table device and sorting system provided by this utility model, a boss and a material-pushing mechanism are set in the first material box. The swing frame, affected by the vibration of the shaking table device and in cooperation with the spring, moves back and forth on the beam, and simultaneously drives the paddle to move, repeatedly agitating the slurry flowing from the slurry pipe to the boss, so that the slurry is further dispersed and flows evenly to the feed opening. This method effectively improves the uniformity of slurry distribution on the bed, thereby improving the sorting effect. At the same time, affected by the flowing slurry and the repeated movement of the swing frame, the paddle swings naturally around the sphere as the axis through the spherical support, so that the paddle can better adapt to the flow characteristics of the slurry when agitating it, thereby improving the slurry dispersion effect.

[0027] The technical solutions of the present invention 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 invention, and not all embodiments. Various changes can be made to the implementation scheme as long as the effects of the present invention can be achieved.
[0028] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.
[0029] Reference Figure 1-4 The shaking table device and sorting system of this implementation plan are described.
[0030] First, the shaking table device of this embodiment includes a feed box 1, which is internally divided into a first feed box 2 and a second feed box 3 by a partition. The first feed box 2 is used to supply mineral slurry, and the second feed box 3 is used to supply liquid water. Both the first feed box 2 and the second feed box 3 have a feed opening 9 on their front sides, through which the mineral slurry and liquid water flow out respectively.
[0031] Furthermore, a hopper with a built-in water supply pipe is installed at one end of the second material box 3. For example... Figure 1 and Figure 2 As shown, a feed box 4 is provided on the rear side of the first feed box 2. The ore to be screened is fed into the feed box 4. The feed box 4 has a built-in water supply pipe and a slurry outlet pipe 7, which is inserted into the first feed box 2. The water supply pipe is strip-shaped, so that the ore is evenly flushed with water in the feed box 4 and flows into the first feed box 2 through the slurry outlet pipe 7.
[0032] It should be noted that both the feed box 4 and the slurry outlet pipe 7 are strip-shaped and are arranged along the length of the first feed box 2. In one feasible embodiment, the strip-shaped design of the feed box 4 and the slurry outlet pipe 7 allows the ore and water to be mixed to form a slurry, which then enters the first feed box 2 in a uniformly distributed manner, is dispersed, and flows out through the feed opening 9.
[0033] Furthermore, in this embodiment, the first material box 2 is provided with a boss 6, and the slurry outlet pipe 7 is located above the boss 6. The side of the boss 6 close to the feed opening 9 is inclined downward to form a slope 8. After the slurry flows out through the slurry outlet pipe 7, it flows onto the boss 6, and then flows through the slope 8 to the feed opening 9.
[0034] In addition, the surface of the inclined plane 8 is provided with multiple recesses 81 and protrusions 82, which are spaced apart and continuously arranged. Specifically, the recesses 81 and protrusions 82 are sequentially connected to form a continuous, curved corrugated shape. When the slurry flows down through the multiple recesses 81 and protrusions 82 on the inclined plane 8, the flow path becomes tortuous, slowing down the flow rate of the slurry and easily generating turbulence and eddies. This increases the mixing and suspension of solid particles in the slurry, facilitating subsequent sorting operations.
[0035] In this embodiment, a material feeding mechanism 5 is provided above the boss 6 to repeatedly move the slurry flowing from the slurry pipe 7 to the boss 6, so that the slurry is further dispersed and flows evenly to the feed opening 9.
[0036] Specifically, the feeding mechanism 5 includes a beam 51 arranged along the length of the first material box 2. A set of paddles, capable of reciprocating on the beam 51, is mounted on the beam 51 and is located in front of the slurry outlet pipe 7. For example, the beam is composed of two circular cross-section rods to ensure that the paddles do not tilt or rotate on the beam 51. Alternatively, the beam can also be a single rectangular cross-section rod.
[0037] In one embodiment, the paddle assembly includes a swing arm 53 and a connecting beam. (See reference) Figure 1 and Figure 3 For example, the swing frame 53 includes several plates and a connecting plate connecting two adjacent plates. The plates are sleeved on the beam 51, and the two ends of the swing frame 53 (i.e., the plates located on both sides) are connected to the two side walls (inner wall and partition of the first material box 2) by springs 52. The connecting beam is set on the swing frame 53, and a lever 54 is set on the connecting beam. When the shaking table device vibrates as a whole, the swing frame 53 is affected by the vibration of the shaking table device and moves back and forth on the beam 51 in cooperation with the springs 52, and simultaneously drives the lever 54 to move, repeatedly agitating the slurry flowing from the slurry pipe 7 to the boss 6, so that the slurry is further dispersed and flows evenly to the feed opening 9.
[0038] Furthermore, the connecting beam includes a rear beam 55 and a front beam 56 arranged side by side, with a lever 54 fitted onto the rear beam 55 and the front beam 56.
[0039] A sphere 58 is provided at the contact point between the front beam 56 and the lever 54. A spherical bracket 59 is provided on the lever 54, which is fitted onto the sphere 58. The spherical bracket 59 serves as a retainer and slides on the sphere 58. During implementation, influenced by the flowing slurry and the repeatedly moving pendulum 53, the lever 54 swings naturally around the sphere 58 via the spherical bracket 59, enhancing the dispersion effect of the slurry.
[0040] In addition, to allow the paddle shifter 54 to swing smoothly, a through hole is provided at the connection between the paddle shifter 54 and the rear beam 55. A rubber sleeve 57 is installed inside the through hole, and the inner diameter of the rubber sleeve 57 is larger than the diameter of the rear beam 55. When the paddle shifter 54 swings to its maximum position, the outer edge of the rubber sleeve 57 abuts against the rear beam 55.
[0041] Secondly, this embodiment also discloses a sorting system, including a shaking table device and a bed 10. The feed box 1 of the shaking table device is located on the side of the top surface of the bed 10. The slurry and water flow to the surface of the bed 10 for vibration sorting through the feed openings 9 on the front sides of the first feed box 2 and the second feed box 3, respectively.
[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
