Description

Technical Field

[0001] This utility model relates to the field of mineral processing shaking table technology, specifically to a mineral processing shaking table screening and protection device. Background Technology

[0002] Mineral processing shaking tables cause mineral particles to move in different directions according to their density and particle size. Starting from the feed trough, the particles spread out diagonally in a fan shape and are discharged sequentially along the edges of the table. The discharge line is long, allowing for the precise production of various products of different qualities, such as concentrate, secondary concentrate, middlings, and tailings. During screening on a shaking table, asymmetrical reciprocating motion is generated through an inclined plane with bed strips on the surface. This motion is achieved by a motor, reducer, and crank-connecting rod mechanism. Three main force fields are generated during operation: one generated by the crank-connecting rod mechanism, propelling the particles longitudinally; another generated by the transverse inclination of the table, promoting lateral movement; and a third generated by the washing water, aiding in particle stratification and separation. These three force fields work synergistically. Denser mineral particles are strongly resisted by the bed strips, exhibiting significant longitudinal movement but weaker lateral movement. Conversely, less dense gangue particles are less resisted by the bed strips and mainly move laterally with the water flow. This results in mineral particles with different characteristics exhibiting different trajectories on the table surface, thus achieving separation. However, during water washing, some mineral particles may not be screened and may be washed out of the shaking table. If no effective protection is provided, the loss of mineral particles over a long period of time will cause unnecessary cost losses. Therefore, we propose a mineral processing shaking table screening protection device. Utility Model Content

[0003] The purpose of this utility model is to provide a protective device for mineral processing shaking table screening, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a mineral processing shaking table screening and protection device, including a mineral processing shaking table, a bottom plate fixedly connected to the bottom of the mineral processing shaking table, a groove formed on the surface of the bottom plate, the groove being elongated and curved, and a filter plate fixedly connected to the corner of the upper surface of the bottom plate, the filter plate having through holes on its surface, and the mesh size being smaller than that of the mineral particles.

[0005] Preferably, it also includes a feeding structure, the bottom side of which is fixedly connected to one side of the upper surface of the mineral processing shaking table.

[0006] Preferably, the feeding structure includes a first inclined plate, the lower surface of which is fixedly connected to one side of the upper surface of the mineral processing shaking table, a through-hole plate fixedly connected to the center of the upper surface of the first inclined plate, a pull rod inserted into the inner cavity of the through-hole plate, the pull rod being "m" shaped and the pull rod and the through-hole plate being clearance fit, a support plate fixedly connected to the other end of the pull rod, a second inclined plate fixedly connected to the lower surface of the support plate, the side wall of the second inclined plate being in contact with the side wall of the first inclined plate, side plates symmetrically fixedly connected to the upper surfaces of the second inclined plate and the first inclined plate, and a vibration motor fixedly connected to the side wall of the side plate.

[0007] Preferably, the joint between the sidewalls of the first inclined plate and the sidewalls of the second inclined plate forms a "V" shape.

[0008] Preferably, the number of side panels is four, and they are arranged symmetrically side by side.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: First, the material preparation is carried out through the feeding structure. The inclined plates on both sides are joined together to form a "V" shape, changing the existing feeding position and raising the feeding height to avoid mineral particle accumulation affecting screening. At the same time, the vibrating motors on both sides are turned on to vibrate. Since the mineral processing shaking table is inclined, the mineral particles will be evenly spread during vibration. Subsequently, the pull rod is pushed forward to make the mineral particles fall. Changing the original opening method allows for more efficient feeding. The vibration of the vibrating motor ensures that no material remains during feeding. The asymmetrical reciprocating motion generated by the mineral processing shaking table causes some mineral particles that fall with the water flow to contact the bottom plate. At the same time, the surface of the bottom plate has grooves to facilitate the settling of mineral particles. It is also equipped with a filter plate for interception. The mesh size of the filter plate is smaller than that of the mineral particles to prevent mineral particles from flowing out and provide sufficient interception and protection for the mineral particles, effectively avoiding unnecessary cost losses.

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.

[0014] Please see Figure 1-2 This utility model provides a screening and protection device for a mineral processing shaking table, including a mineral processing shaking table 1. A base plate 2 is fixedly connected to the bottom of the mineral processing shaking table 1. A groove 3 is formed on the surface of the base plate 2. The groove 3 is long and curved. A filter plate 4 is fixedly connected to the upper surface corner of the base plate 2. The surface of the filter plate 4 has through holes and the mesh size is smaller than that of the mineral particles.

[0015] It also includes a feeding structure 5, the bottom side of which is fixedly connected to the upper surface of the mineral processing shaking table 1.

[0016] The feeding structure 5 includes a first inclined plate 51. The lower surface of the first inclined plate 51 is fixedly connected to one side of the upper surface of the mineral processing shaking table 1. A through-hole plate 52 is fixedly connected to the center of the upper surface of the first inclined plate 51. A pull rod 53 is inserted into the inner cavity of the through-hole plate 52. The pull rod 53 is "m" shaped and the pull rod 53 and the through-hole plate 52 are clearance-fitted. A support plate 54 is fixedly connected to the other end of the pull rod 53. A second inclined plate 55 is fixedly connected to the lower surface of the support plate 54. The side wall of the second inclined plate 55 is in contact with the side wall of the first inclined plate 51. Side plates 56 are symmetrically fixedly connected to the upper surfaces of the second inclined plate 55 and the first inclined plate 51. A vibration motor 57 is fixedly connected to the side wall of the side plate 56.

[0017] The sidewalls of the first inclined plate 51 and the second inclined plate 55 meet in a "V" shape.

[0018] There are four side panels 56, which are arranged symmetrically side by side.

[0019] Working principle: When the mineral processing shaking table 1 is used for screening, the material is first prepared by the feeding structure 5. The feeding structure 5 is fixed to one end of the mineral processing shaking table 1 by the first inclined plate 51. At the same time, a through plate 52 is set on the top of the first inclined plate 51. A pull rod 53 is sleeved on the through plate 52. A support plate 54 is fixed to the other end of the pull rod 53. A second inclined plate 55 is fixed to the bottom of the support plate 54. The two inclined plates are joined together to form a "V" shape. The operator pulls the pull rod 53 to keep the two inclined plates stable. Another operator pours the mineral particles into it and turns on the vibration motors 57 on both sides to vibrate. The inclined setting ensures that the mineral particles are evenly distributed during vibration. The subsequent forward push of the pull rod 53 causes the mineral particles to fall. The vibration of the vibration motor 57 ensures that no material remains during feeding. The asymmetrical reciprocating motion generated by the mineral processing shaking table 1, along with the inclined plane and the bed strips laid on the surface, and the washing water, helps the particles to stratify and separate. The particles are collected in a bucket-like container. Some of the mineral particles that fall with the water flow will contact the bottom plate 2. At the same time, the surface of the bottom plate 2 has grooves 3 to facilitate the sedimentation of the mineral particles. It is also equipped with a filter plate 4 for interception. The mesh size of the filter plate 4 is smaller than that of the mineral particles to prevent the mineral particles from flowing out, providing sufficient interception and protection for the mineral particles and effectively avoiding unnecessary cost losses.
