[0002] Barite tailings refer to the waste residue produced during the mining and processing of barite (barium sulfate) ore, that is, the tailings left after the ore is processed. Barite is an important non-metallic mineral resource, widely used in chemical, petroleum, construction and other industries, especially in the oil drilling industry, as a weighting agent to increase the density of drilling fluid.

[0003] One way to separate barite tailings is to use a screening device to separate large-size and small-size tailings to avoid mixing of large-size and small-size tailings, which would have an adverse effect on subsequent production. When the screening device is separating the tailings, large-size tailings are easily retained on the top surface of the screen plate of the screening device, while large-size tailings are not easy to collect and are retained on the screen plate, affecting subsequent tailings separation.

[0025] The front and rear side surfaces of the movable column 2 slide in contact with the front and rear inner surfaces of the box body 1, the distance between the upper and lower end surfaces of the movable column 2 corresponds to the distance from the partition 1 5 to the partition 2 6, and the front and rear ends of the fixed column 3 contact the front and rear inner surfaces of the box body 1 respectively.

[0026] A connecting rod 15 is fixed to the top surface of the movable column 2. The connecting rod 15 is a long strip rod arranged along the length direction of the movable column 2. The driving member 1 includes a screw 13 and a motor 14. The screw 13 is threadedly connected to the connecting rod 15.

When the connecting rod 15 contacts the partition 2 6, the right end of the movable column 2 is flush with the right side surface of the partition 2 6.

[0027] The arc groove 1 7 and the arc groove 2 8 are both on the same circle. The middle parts of the front and rear ends of the screen plate 4 are rotatably connected to the front and rear side plates of the box body 1 via the rotating shaft 1 17 and the rotating shaft 2 18 respectively. The left end of the screen plate 4 is an arc surface corresponding to the arc groove 1 7, and the right end is an arc surface corresponding to the arc groove 2 8. The front and rear ends of the screen plate slide and contact the front and rear inner surfaces of the box body respectively.

[0028] The driving member 2 includes a gear 16, a motor 24 and a rotating shaft 3 19. The front end of the rotating shaft 17 passes through the front plate of the box body 1 and is connected to the gear 16. The rotating shaft 17 on the front side of the box body 1 is covered with a torsion spring 20. The front and rear ends of the torsion spring 20 are respectively connected to the gear 16 and the front plate of the box body 1. A motor 24 with an output end facing forward is fixed to the outside of the front side of the box body 1 on the upper side of the torsion spring 20. The output end of the motor 2 is connected to the rotating shaft 3 19. A fan ring plate 21 is fixed to the upper end of the peripheral wall of the rotating shaft 3 19. The inner ring surface of the fan ring plate 21 is fixedly connected to the peripheral wall of the rotating shaft 3 19. The fan ring plate 21 and the gear 16 are opposite to each other in upper and lower directions. The outer ring surface of the fan ring plate 21 is convex upward, and teeth 22 are arranged at intervals on the outer ring surface. When the outer ring surface of the fan ring plate 21 is convex downward, the teeth 22 on the fan ring plate 21 mesh with the gear 16.

[0029] When the torsion spring 20 is in a natural state, the left end of the sieve plate 4 contacts the lower end of arc groove 1 7 and the right end contacts the upper end of arc groove 2 8. When the teeth 22 on the fan ring plate 21 drive the gear 16 to rotate to the limit state, the left end of the sieve plate 4 contacts the upper end of arc groove 1 7 and the right end contacts the lower end of arc groove 2 8.

[0030] When in use, in the initial state, the torsion spring 20 is in a natural state, the sieve plate 4 is in a state of being lower on the left and higher on the right, and the barite tailings to be screened are fed through the upper opening of the box body 1, and the barite tailings fall on the top surface of the sieve plate 4 until the barite tailings are close to the lower end of the partition plate 2 6; start the motor 2, and the motor 2 drives the fan ring plate 21 to rotate counterclockwise via the rotating shaft 3 19 (the counterclockwise rotation of the fan ring plate 21 is Figure 1 ), when the outer ring surface of the fan ring plate 21 is convex and faces downward, the teeth 22 on the fan ring plate 21 mesh with the drive gear 16 to rotate clockwise (the clockwise rotation of the gear 16 is Figure 1 The gear 16 drives the screen plate 4 to rotate clockwise via the rotating shaft 17, and the torsion spring 20 is twisted. During the clockwise rotation of the screen plate 4, the screen plate 4 gradually becomes higher on the left and lower on the right, and the barite tailings on the screen plate 4 move to the right. As the rotating shaft 3 19 continues to rotate, after the teeth 22 on the fan ring plate 21 disengage from the gear 16, under the restoring force of the torsion spring 20, the gear 16 drives the screen plate 4 to rotate counterclockwise via the rotating shaft 17 to return to the initial position, and the screen plate 4 returns from the state of being higher on the left and lower on the right to the state of being lower on the left and higher on the right; therefore, when the motor 24 drives the rotating shaft 3 19 to rotate continuously, the screen plate 4 can be in a state of being higher on the left and lower on the right or lower on the left and higher on the right, and the barite tailings reciprocate left and right on the screen plate 4, which is conducive to the tailings smaller than the sieve hole diameter on the screen plate 4 falling onto the guide plate 2 11 through the sieve hole;

[0031] After the separation is completed, the tailings with large particle sizes are retained on the top surface of the screen plate 4, the motor 2 stops working, and the outer ring surface of the fan ring plate 21 is raised upward. At this time, the torsion spring 20 is in a natural state, and the screen plate 4 is in a state of low left and high right. Since the front and rear ends of the movable column contact the front and rear inner surfaces of the box body, when the screw rotates, the movable column can only move to the left or right. The motor 14 drives the screw 13 to rotate, and the driving connecting rod 15 drives the movable column 2 to move to the left. When the left end of the movable column 2 is separated from between the partition 1 5 and the partition 2 6, the tailings with large particle sizes on the screen plate 4 fall to the lower left onto the guide plate 1 9 under the action of its own weight and are collected;

[0032] Open the discharge door 10 and the discharge door 2 12 to facilitate the discharge of ores with large particle sizes and small particle sizes.

[0033] The preferred implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings; however, the present invention is not limited to the above-mentioned embodiments. Without violating the spirit of the present invention, i.e., the disclosure scope, any equivalent or equivalent deformation or replacement of the technical solution of the present invention shall fall within the protection scope of the present invention.
