Description

Technical Field

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

[0002] Spiral sluices are commonly used equipment in the field of mineral processing. The slurry enters evenly from the top. Inside the spiral channel, mineral particles are separated according to the differences in forces such as gravity and centrifugal force. The denser minerals are closer to the inside of the sluice, while the less dense minerals are closer to the outside. Finally, they are collected in different collection tanks at the bottom to complete the mineral processing process.

[0003] However, existing spiral sluices for mining have significant shortcomings. In actual mining scenarios, the extracted ore often carries a large amount of soil. Because spiral sluices lack a ore-washing function during the feeding stage, unwashed ore enters directly, causing soil to mix into the ore solution. This situation leads to a series of adverse effects. On the one hand, the soil complicates the composition of the ore solution, seriously interfering with the normal separation process of mineral particles within the spiral sluice based on gravity, centrifugal force, etc., and significantly reducing beneficiation efficiency. On the other hand, the presence of soil seriously affects the quality of the final beneficiated product, making it difficult to meet the stringent standards for concentrate quality in industrial production. In view of this, a spiral sluice for mining beneficiation is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a spiral chute for mineral processing. This solution addresses the issue that the spiral chute lacks a ore washing function during the feeding stage, resulting in unwashed ore entering directly and causing mud to mix into the ore solution. This situation leads to a series of adverse effects. On the one hand, the mud complicates the composition of the ore solution, seriously interfering with the normal separation process of mineral particles in the spiral chute based on gravity, centrifugal force, etc., and significantly reducing the mineral processing efficiency. On the other hand, the presence of mud seriously affects the quality of the final mineral processing product.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a spiral chute for mineral processing, comprising a support frame, wherein the support frame is in the shape of a cross, a spiral chute body is provided inside the support frame, a water injection pump is fixedly connected to the top of the support frame, a water injection pipe is fixedly connected to the outlet of the water injection pump, and the water injection pipe is located at the feed inlet of the spiral chute body.

[0006] A cleaning box is provided on one side of the support frame, and a connecting box is fixedly connected to the cleaning box;

[0007] The bottom of the cleaning tank is fixedly connected to a first motor, and the bottom of the connecting box is fixedly connected to a second motor.

[0008] The cleaning box is equipped with a cleaning mechanism, and the connecting box is connected to the inside of the cleaning box.

[0009] Preferably, the cleaning mechanism includes a rotating shaft, which is fixedly connected to the output end of the first motor. A cleaning rod is fixedly connected to the rotating shaft, and cleaning brushes are fixedly connected to both sides of the cleaning rod.

[0010] The cleaning mechanism also includes a conveying pipe, which is fixedly connected to the connecting box, and an auger is installed inside the conveying pipe;

[0011] The auger is fixedly connected to the output end of the second motor.

[0012] Preferably, the auger has a through hole.

[0013] Preferably, the cleaning mechanism further includes a water distribution ring, which is fixedly connected to the surface of the conveying pipe;

[0014] A water distribution pipe is fixedly connected to the water distribution ring, and an installation hole is opened on the inner wall of the material conveying pipe;

[0015] The mounting hole contains a water nozzle, which is connected to the water distribution pipe.

[0016] Preferably, the inner bottom surface of the cleaning tank is inclined towards the connecting box.

[0017] Preferably, a drain pipe is fixedly connected to the bottom of the connecting box, and a valve is installed on the drain pipe.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This mine uses a spiral chute for mineral processing. After the ore is fed into the washing tank, the first motor is started. The output of the first motor drives the rotating shaft, cleaning rod, and washing brush to rotate together. The washing brush scrubs the surface of the ore, removing dirt and other adhering materials, thus ensuring the subsequent screening effect. Since the bottom of the washing tank is inclined, the ore flows towards the connecting box. At this time, the second motor is started, and the output of the second motor drives the auger to rotate. The auger then transports the washed ore to the spiral chute body. At this time, the water flowing out of the water injection pipe completes the mineral processing operation, thereby improving the mineral processing efficiency and quality.

[0020] The ore beneficiation process uses a spiral chute. During the process of conveying ore by the screw conveyor, water is supplied to the water distribution ring through an external water supply device. This causes the water to be sprayed out through the water distribution pipe and spray head, thereby achieving the purpose of washing the ore again, thoroughly cleaning the surface deposits, and ensuring the beneficiation effect.

[0031] Please see Figure 1-4This utility model provides a technical solution: a spiral chute for mineral processing, including a support frame 1, the support frame 1 is in the shape of a cross, a spiral chute body 2 is provided inside the support frame 1, a water injection pump 3 is fixedly connected to the top of the support frame 1, a water injection pipe 4 is fixedly connected to the outlet of the water injection pump 3, and the water injection pipe 4 is located at the feed inlet of the spiral chute body 2.

[0032] A cleaning box 5 is provided on one side of the support frame 1, and a connecting box 6 is fixedly connected to the cleaning box 5;

[0033] The bottom of the cleaning tank 5 is fixedly connected to the first motor 8, and the bottom of the connecting box 6 is fixedly connected to the second motor 9;

[0034] The cleaning tank 5 is equipped with a cleaning mechanism, and the connecting box 6 is connected to the interior of the cleaning tank 5.

[0035] When it is necessary to select ore, the ore can be put into the washing tank 5 and water can be added to the washing tank 5. At this time, the washing mechanism will clean the mud and other impurities adhering to the surface of the ore, thus ensuring the subsequent screening effect.

[0036] The bottom of the connecting box 6 is fixedly connected to a drain pipe, and a valve is installed on the drain pipe;

[0037] The bottom of the cleaning tank 5 is inclined towards the connecting box 6;

[0038] Furthermore, the cleaning mechanism includes a rotating shaft 12, which is fixedly connected to the output end of the first motor 8. A cleaning rod 13 is fixedly connected to the rotating shaft 12, and cleaning brushes 14 are fixedly connected to both sides of the cleaning rod 13.

[0040] Screw 15 is fixedly connected to the output end of the second motor 9;

[0041] After the ore is placed inside the washing tank 5, the first motor 8 is started. The output of the first motor 8 drives the rotating shaft 12, the cleaning rod 13 and the cleaning brush 14 to rotate together. Therefore, the cleaning brush 14 scrubs the surface of the ore to remove dirt and other attachments, thus ensuring the subsequent screening effect. Since the bottom of the washing tank 5 is inclined, the ore flows towards the connecting box 6. At this time, the second motor 9 is started. The output of the second motor 9 drives the auger 15 to rotate. Therefore, the auger 15 transports the cleaned ore to the spiral chute body 2. At this time, the water flowing out of the water injection pipe 4 completes the mineral processing operation.

[0042] Among them, the screw conveyor 15 has a through hole;

[0043] By opening through holes in the auger 15, excess water and soil can be discharged through the through holes during the auger 15 transport of ore, thus preventing soil from being transported onto the spiral chute body 2, thereby ensuring the mineral processing effect.

[0044] Furthermore, the cleaning mechanism also includes a water distribution ring 10, which is fixedly connected to the surface of the material conveying pipe 7.

[0045] A water distribution pipe 11 is fixedly connected to the water distribution ring 10, and an installation hole 16 is provided on the inner wall of the material conveying pipe 7.

[0046] A water nozzle 17 is installed inside the mounting hole 16, and the water nozzle 17 is connected to the water distribution pipe 11.

[0047] The water distribution ring 10 is interconnected with the external water supply equipment;

[0048] During the process of conveying ore by the screw conveyor 15, water is supplied to the water distribution ring 10 through an external water supply device, so that the water is sprayed out through the water distribution pipe 11 and the water nozzle 17, thereby achieving the purpose of cleaning the ore again, thoroughly cleaning the surface deposits, and thus ensuring the mineral processing effect.

[0049] Working principle: When the ore is put into the washing tank 5, the first motor 8 is started. The output of the first motor 8 drives the rotating shaft 12, the cleaning rod 13 and the cleaning brush 14 to rotate together. Therefore, the cleaning brush 14 scrubs the surface of the ore to remove dirt and other attachments, thus ensuring the subsequent screening effect. Since the bottom of the washing tank 5 is inclined, the ore flows towards the connecting box 6. At this time, the second motor 9 is started. The output of the second motor 9 drives the auger 15 to rotate. Therefore, the auger 15 transports the cleaned ore to the spiral chute body 2. At this time, the water flowing out of the water injection pipe 4 completes the mineral processing operation.

[0050] During the process of conveying ore by the screw conveyor 15, water is supplied to the water distribution ring 10 through an external water supply device, so that the water is sprayed out through the water distribution pipe 11 and the water spray head 17, thereby achieving the purpose of cleaning the ore again, thoroughly cleaning the surface deposits, and thus ensuring the mineral processing effect.

[0051] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
