Description

Technical Field

[0001] This utility model relates to the field of mineral processing shaking table technology, specifically a mineral processing shaking table with a multi-layer vibration mineral processing mechanism. Background Technology

[0002] A shaking table is a gravity separation device used to separate fine-grained materials. The slurry is added to the feed trough, and after adjusting the concentration to approximately 20%-25%, it flows onto the table surface. Under the action of water flow and table vibration, the mineral particles loosen and stratify within the table grooves. Heavy mineral particles move in the opposite direction to the drive end due to table vibration, forming concentrate which is discharged from the concentrate end. Lighter mineral particles are pushed upwards by the water flow and move laterally at an incline, being discharged as tailings. Due to differences in specific gravity and particle size, the product is distributed in a fan-shaped pattern along the diagonal from the feed trough.

[0003] Most of the mineral processing shaking tables currently on the market have a fixed internal mineral processing mechanism. This fixed structural design greatly limits the flexibility of the shaking table in different operating scenarios, making it difficult to make targeted screening adjustments according to the characteristics of the ore. Ultimately, this results in the ore screening efficiency remaining at a low level for a long time, becoming a major bottleneck restricting the improvement of mineral processing capacity. Utility Model Content

[0006] The vibration mechanism includes a support base, which is disposed inside the shaking table body. A cam is disposed in the middle of the support base. A rotating rod is fixedly connected to the inner ring of the cam. A support frame is rotatably connected to the surface of the rotating rod. A connecting plate is fixedly connected to the side of the support frame away from the cam. The connecting plate is fixedly connected to one side of the surface of the shaking table body.

[0007] Preferably, a pulley assembly is driven to the surface of the rotating rod, and an output shaft is driven to the side of the pulley assembly opposite to the rotating rod. A motor is fixedly connected to one end of the output shaft, and a fixing plate is fixedly connected to the surface of the motor. The fixing plate is fixedly connected to the surface of the shaking table body.

[0008] Preferably, the support frame is designed in an "H" shape, and the cam is disposed between the support frame and the support base.

[0009] Preferably, the pulley assembly is made of ductile iron and is disposed inside the shaking table body.

[0010] Preferably, the support mechanism includes a guide plate, which is disposed inside the shaking table body. The number of guide plates is three, and the three guide plates are designed at an angle. The support base is fixedly connected to the surface of the top guide plate.

[0011] Preferably, vertical plates are fixedly connected to the surfaces of the three guide plates, and the vertical plates are disposed on both sides of the shaking table body.

[0012] Preferably, connecting blocks are fixedly connected to both sides of the guide plate, and a fixing rod is slidably connected inside the connecting block.

[0016] Compared with the prior art, this utility model provides a mineral processing shaking table with a multi-layer vibration mineral processing mechanism, which has the following beneficial effects:

[0017] 1. This mineral processing shaking table with a multi-layer vibration separation mechanism accurately transmits the up-and-down movement to each guide plate through the set vibration mechanism, so that multiple guide plates generate high-frequency vibration at the same time. During the vibration process, ores of different properties generate different movement trajectories on the surface of the guide plates due to differences in particle size, density and shape, thereby realizing the preliminary separation of ores and greatly improving the mineral processing efficiency.

[0018] 2. This multi-layer vibrating mineral processing shaking table, through its support mechanism, allows the connecting block to slide at high frequency along the axial direction of the fixed rod when the guide plate is displaced by the cam. During the sliding process, the connecting block continuously compresses the spring installed between it and the fixed support, causing the spring to undergo elastic deformation and store elastic potential energy. When the force of the cam weakens, the spring releases the stored elastic potential energy and pushes the connecting block to move in the opposite direction with its own elastic restoring force, thereby driving the guide plate to move in the opposite direction. This cycle repeats continuously, keeping the guide plate in a stable and efficient vibration state, providing a stable and reliable power source for the precise separation of ore.

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.

[0027] This utility model provides a technical solution:

[0028] Example 1:

[0029] Combination Figure 1-4 A mineral processing shaking table with a multi-layer vibration mineral processing mechanism includes a shaking table body 1, a vibration mechanism 2 is provided inside the shaking table body 1, and a support mechanism 3 is provided at the bottom of the vibration mechanism 2;

[0030] The vibration mechanism 2 includes a support base 25, which is located inside the shaker body 1. A cam 27 is located in the middle of the support base 25. A rotating rod 26 is fixedly connected to the inner ring of the cam 27. A support frame 23 is rotatably connected to the surface of the rotating rod 26. A connecting plate 24 is fixedly connected to the side of the support frame 23 away from the cam 27. The connecting plate 24 is fixedly connected to one side of the surface of the shaker body 1.

[0031] Furthermore, a pulley assembly is connected to the surface of the rotating rod 26. An output shaft is connected to the side of the pulley assembly opposite to the rotating rod 26. A motor 22 is fixedly connected to one end of the output shaft. A fixing plate 21 is fixedly connected to the surface of the motor 22. The fixing plate 21 is fixedly connected to the surface of the shaking table body 1. The support frame 23 has an "H" shape design. A cam 27 is set between the support frame 23 and the support seat 25. The pulley assembly is made of ductile iron and is set inside the shaking table body 1.

[0032] Example 2:

[0033] See Figure 1 and Figure 5 Based on Embodiment 1, the support mechanism 3 includes a guide plate 33, which is disposed inside the shaking table body 1. There are three guide plates 33, which are inclined. The support base 25 is fixedly connected to the surface of the top guide plate 33.

[0034] Furthermore, vertical plates 31 are fixedly connected to the surfaces of the three guide plates 33. The vertical plates 31 are located on both sides of the shaking table body 1. Connecting blocks 36 are fixedly connected to both sides of the guide plates 33. Fixed rods 32 are slidably connected inside the connecting blocks 36. The fixed rods 32 are fixedly connected to the bottom of the shaking table body 1. Both fixed rods 32 are located on both sides of the shaking table body 1.

[0035] Furthermore, a spring 37 is sleeved on the surface of the fixing rod 32. The spring 37 is located at the bottom of the connecting block 36. There are several springs 37. A support member 35 is fixedly connected to the surface of the fixing rod 32. The support member 35 is fixedly connected to the inner wall of the shaking table body 1. A sliding groove is opened on one side of the shaking table body 1. A sliding plate 34 is slidably connected in the sliding groove. Both sliding plates 34 are fixedly connected to both sides of the guide plate 33.

[0036] In actual operation, when this device is put into use, the operator first places different types and specifications of ore raw materials into the different levels of guide plates 33 according to the predetermined process. These guide plates 33 are arranged in an orderly manner in a stepped shape, forming a multi-layer sorting structure. Each layer of guide plate 33 corresponds to a specific sorting particle size or mineral type. After the feeding operation is completed, the motor 22 is started. The motor 22 outputs strong power and transmits the power precisely to the rotating rod 26 through the transmission system, thereby driving the cam 27 installed on the rotating rod 26 to start rotating at a uniform speed.

[0037] As the cam 27 continues to rotate, its unique contour curve interacts with the support seat 25. Based on the mechanical transmission principle, it periodically applies force to the support seat 25, driving the support seat 25 to move up and down in a regular manner in the vertical direction. This up and down movement is precisely transmitted to each guide plate 33, causing multiple guide plates 33 to vibrate at high frequency simultaneously. During the vibration process, ores of different properties, due to differences in particle size, density, and shape, generate different movement trajectories on the surface of the guide plates 33, thereby achieving preliminary separation of the ore and greatly improving the beneficiation efficiency.

[0038] During the vibration of the guide plate 33, the elastic buffer system consisting of the connecting block 36, the fixed rod 32, and the spring 37 plays a crucial role. The connecting block 36 is tightly fitted onto the surface of the fixed rod 32. When the guide plate 33 is driven by the cam 27 to move, the connecting block 36 will slide at high frequency along the axial direction of the fixed rod 32. During the sliding process, the connecting block 36 will continuously compress the spring 37 installed between it and the fixed support, causing the spring 37 to undergo elastic deformation and store elastic potential energy. When the force of the cam 27 weakens, the spring 37 will release the stored elastic potential energy and push the connecting block 36 to move in the opposite direction with its own elastic restoring force, thereby driving the guide plate 33 to move in the opposite direction. This cycle repeats, allowing the guide plate 33 to maintain a stable and efficient vibration state, providing stable and reliable power conditions for the precise separation of ore.
