Description

Technical Field

[0001] This utility model relates to the field of mining equipment technology, and in particular to a spiral chute mining device for a mineral processing system. Background Technology

[0002] A spiral sluice is a type of spiral mineral concentrator. It allows the slurry to rotate in a spiral motion along the surface of the spiral sluice under the action of gravity. The slurry contains mineral particles with different specific gravities. During the sluice process, the mineral particles with different specific gravities separate and stratify due to differences in buoyancy, gravity, and centrifugal force. Heavy minerals settle quickly and are close to the bottom of the sluice. Due to the influence of friction, they slow down and concentrate towards the inner edge of the spiral sluice. Light minerals, due to settling, are in the upper layer of the slurry. They move faster and are subject to greater centrifugal force, so they concentrate towards the outer edge of the spiral sluice. In this way, the material to be processed is separated.

[0003] However, different slurries have different mineral proportions, and the minerals are separated at different locations during separation. When different slurries are used in the same spiral chute, the separation accuracy will be reduced and the separation effect will be poor. Utility Model Content

[0034] To achieve the above objectives and effects, the technical means and structure adopted by this utility model are described in detail with reference to the accompanying drawings, focusing on the features and functions of the preferred embodiments of this utility model.

[0035] As attached Figures 1-4 As shown, this utility model provides a spiral chute mining device for a mineral processing system, comprising:

[0036] Main body 1, which is a hollow cylinder with an opening at the top;

[0037] Rotating shaft 2 is rotatably connected to the main body 1 on the same axis;

[0038] Spiral chute 3 is located on the outside of rotating shaft 2 and is fixedly connected to rotating shaft 2 coaxially;

[0039] Feeding hopper 4 is located on the top of the main body 1 and is opposite to the spiral chute 3;

[0040] Water hopper 5 is located on the top of the main body 1. Water hopper 5 is opposite to the spiral chute 3. Water hopper 5 and material hopper 4 are arranged radially along the spiral chute 3.

[0041] The ore separating component is located at the outlet end of the spiral chute 3 and is used to divide the spiral chute 3 into multiple flow channels.

[0042] The receiving trough 6 has multiple receiving chambers. The receiving trough 6 is located below the spiral chute 3, and the multiple receiving chambers correspond to multiple flow channels of the spiral chute 3.

[0043] Drive component 7 is used to drive the rotating shaft 2 to rotate.

[0044] Specifically, the drive component 7 is a drive motor, which is located at the bottom of the main body 1. The drive shaft of the drive motor is connected through a coupling shaft 2, which passes through the main body 1 and is rotatably connected to the main body 1.

[0045] Specifically, the feeding hopper 4 and the water feeding hopper 5 are coaxial annular structures. The water feeding hopper 5 is located inside the feeding hopper 4 and is coaxially and fixedly connected to the rotating shaft 2. The feeding hopper 4 is also fixedly connected to the water feeding hopper. Both the bottom of the water feeding hopper 5 and the feeding hopper 4 are equipped with feeding pipes, the other end of which is located inside the spiral chute 3. The bottoms of both the water feeding hopper 5 and the feeding hopper 4 are inclined towards their respective feeding pipes.

[0046] In this embodiment, the receiving groove 6 is circular and fixedly connected to the rotating shaft 2 coaxially. Multiple circular partitions 8, coaxial with the receiving groove 6, are arranged inside the receiving groove 6. The partitions 8 have different diameters and are arranged radially along the receiving groove 6, forming multiple circular receiving cavities. Each receiving cavity has a discharge port at its bottom, and the bottom of the receiving cavity is inclined towards the discharge port.

[0047] In this embodiment, the mining component includes:

[0048] Cover plate 9 is set at the top of the end of the spiral chute 3, and the width of cover plate 9 is the same as the width of spiral chute 3.

[0049] The slide rail is arranged along the width direction of the cover plate 9 and located at the bottom of the cover plate 9. Multiple sliders are provided on the slide rail.

[0050] The separating plates 10 are fixedly mounted on the slider. The top of the separating plates 10 is slidably and sealingly connected to the cover plate 9, and the bottom of the separating plates 10 is slidably and sealingly connected to the spiral chute 3. Multiple separating plates 10 divide the end of the spiral chute 3 into different slurry outlets, allowing the sorted slurry to exit from different outlets, thus completing the sorting process. During use, operators can adjust the position of the separating plates 10 according to the actual sorting situation, changing the size and position of the different slurry outlets to improve the accuracy of the sorting.

[0051] Specifically, a flexible baffle 11 is provided at the end of the ore separating plate 10 away from the spiral chute 3, and the other end of the flexible baffle 11 is connected to the partition plate 8. After the position of the ore separating plate 10 changes, one end of the flexible baffle 11 will form a channel along with one end of the ore separating plate 10, so that the slurry can accurately enter the corresponding receiving cavity in the receiving trough 6.

[0052] In actual use, mineral materials are injected into the feeding hopper 4, and water is injected into the water feeding hopper 5. The mineral materials and water flow into the spiral chute 3 through their feed pipes and form a slurry. Under the action of gravity, the slurry spirals downward along the spiral chute 3. Under the action of centrifugal force, materials of different weights will separate and leave from different slurry outlets at the end of the spiral chute 3 into different receiving chambers in the receiving trough 6 for collection.

[0053] At the same time, the drive component 7 will drive the rotating shaft 2 to rotate, causing the spiral chute 3 to rotate accordingly, increasing the centrifugal force of the slurry in the spiral chute 3 and improving the separation efficiency.

[0054] In this embodiment, a sampling device is installed inside the spiral chute 3, and the sampling device is located near the ore-separating component. The sampling device includes:

[0055] The gantry frame 12 has two legs respectively set on the two side plates of the spiral chute 3, and the crossbeam of the gantry frame 12 is set along the radial direction of the spiral chute 3.

[0056] Multiple electric telescopic rods 13 are evenly distributed at the bottom of the crossbeam of the gantry frame 12 and are set along the length of the crossbeam.

[0057] Multiple sampling boxes 14 are mounted on the gantry frame 12. Each sampling box 14 contains an analysis device and a suction pump. Each sampling box 14 corresponds to a multiple electric telescopic rod 13.

[0058] Multiple flexible sampling tubes 15 are respectively installed on multiple electric telescopic rods 13. The first end of the flexible sampling tube 15 is located below the electric telescopic rod 13, and the second end is connected to the corresponding sampling box 14. The second end of the flexible sampling tube 15 is equipped with an electromagnetic valve.

[0059] In mineral processing, the sampling device operates intermittently: First, the solenoid valve opens, the electric telescopic rod 13 extends, the first end of the flexible sampling tube 15 extends into the spiral chute 3, the suction pump operates, and the slurry at the corresponding position is sucked into the sampling box 14. Then the solenoid valve closes, and the analysis device in the sampling box 14 analyzes the slurry to obtain the mineral type. The staff can adjust the position of the mineral sorting plate 10 according to the sampling results to improve the mineral processing accuracy.

[0060] In this embodiment, the slide rail is an electric slide rail, and the slide rail is electrically connected to a controller. The controller is electrically connected to the analysis device and the solenoid valve.

[0061] Specifically, the analysis device can be a high-definition camera. The high-definition camera takes pictures of the slurry collected in the sampling box 14 and uploads them to the controller. The controller analyzes the specific slurry type and automatically adjusts the position of the ore separating plate 10 according to the distribution of slurry types, so that the ore separating plate 10 is closer to the position of slurry type stratification, thereby improving the beneficiation accuracy.

[0062] In another embodiment, a vibration motor is provided at the bottom of the spiral chute 3. The vibration motor is close to the inlet end of the spiral chute 3, so that the slurry that has just entered the spiral chute 3 is vibrated by the vibration motor, the slurry is dispersed and the separation efficiency is improved.
