Description

Technical Field

[0001] This invention relates to the field of mineral processing equipment technology, and in particular to an iron removal mineral processing machine. Background Technology

[0002] Mineral processing equipment separates different minerals in an ore based on their physical and chemical properties, using appropriate physical and chemical methods to facilitate its use. In mineral processing, where high iron content is required, iron removal equipment is needed to further refine the roughing material and remove iron, reducing the iron content in the ore.

[0003] Existing iron removal equipment uses a drum with magnetic devices installed in the internal gaps. When the drum rotates, iron in the slurry flowing from the drum's periphery is attracted to the drum surface by the magnetic devices. After leaving the magnetic area as the drum rotates, the iron is thrown out, completing the iron screening. In this method, the slurry has a simple flow channel structure during the flow process, which makes it impossible to precisely control the slurry flow rate and volume, reducing the capture efficiency of magnetic minerals. It also easily causes slurry deposition and blockage, reducing the separation effect. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that the simple flow channel structure of the slurry during the flow process makes it impossible to precisely control the slurry flow rate and flow rate, which reduces the capture efficiency of magnetic minerals. Therefore, an iron removal beneficiation machine is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an iron removal ore beneficiation machine, including a support frame, and further comprising: The tank is fixedly connected to the support. The bottom of the tank includes a front section, a stepped structure and a rear section. The front section is close to the inlet end of the tank and the rear section is close to the outlet end of the tank. The stepped structure is connected between the front section and the rear section. The overall depth of the stepped structure increases and then decreases from the inlet end to the outlet end. Adjustable baffles, multiple of which are connected between the front section and the stepped structure and at the depth inflection point of the stepped structure; Protrusions, multiple protrusions connected to the stepped structure; A feeding assembly is connected to the top of the tank inlet end, and the output end of the feeding assembly points into the tank inlet end; The iron removal mechanism is connected to the tank body. The input end of the iron removal mechanism extends into the tank body, the outlet end of the tank body is connected to the concentrate end, and the output end of the iron removal mechanism points to the concentrate end. The iron removal mechanism is used to magnetically attract magnetic materials in the slurry in the tank body and transport them to the concentrate end. The tailings pipe has a tailings hole between the stepped structure and the rear section, and the tailings pipe is connected to the bottom of the tailings hole.

[0006] In the aforementioned iron removal beneficiation machine, the stepped structure includes steps I, II, III, IV, V, and VI. Steps I and II are the initial stage, steps III and IV are the intermediate enhancement stage, and steps V and VI are the final transition stage. The depths of steps I, II, and III gradually increase, while the depths of steps III, IV, V, and VI gradually decrease. The depth of step I is greater than the depth of the preceding section, and the depth of step VI is less than the depth of the preceding section but greater than the depth of the following section.

[0007] In the aforementioned iron removal and beneficiation machine, multiple adjusting baffles are fixedly connected between the front section and step I, and between step III and step IV.

[0008] In the aforementioned iron removal and beneficiation machine, the adjusting baffle adopts a structure that is telescopic in the height direction.

[0009] In the aforementioned iron removal beneficiation machine, the plurality of protrusions connected to each step are evenly spaced, wherein the number of protrusions in the final transition stage is less than the number of protrusions in the intermediate enhancement stage, but greater than the number of protrusions in the initial stage.

[0010] In the aforementioned iron removal ore beneficiation machine, the protrusion has a semi-circular structure.

[0011] In the aforementioned iron removal and beneficiation machine, the feeding assembly includes a feed box, which is fixedly connected to the top of the tank. A water spray pipe is connected to the bottom of the feed box. Multiple feed ports are opened on one side of the water spray pipe, and the output direction of the multiple feed ports points to the inlet end of the tank. One end of the water spray pipe is connected to the output end of an external water supply source.

[0012] In the aforementioned iron removal beneficiation machine, the iron removal mechanism includes a motor, a motor base is fixedly connected to the support, the motor is mounted on the motor base, a drum is coaxially fixedly connected to the output end of the motor, the bottom of the drum is clearance-fitted with the bottom of the tank, a magnetic system is provided in the clearance at the bottom of the drum, a mounting frame is mounted on the support away from the motor base, a magnetic system adjustment device is connected to the mounting frame, the output end of the magnetic system adjustment device coaxially passes through the drum and is fixedly connected to the magnetic system, wherein the magnetic system adjustment device is used to adjust the angle and position of the magnetic system, and the point where the drum rotates away from the magnetic system is located above the concentrate end.

[0013] In the aforementioned iron removal and beneficiation machine, the drum includes an end cover, a cylinder body, and a cylindrical shaft. Both ends of the cylinder body are coaxially and fixedly connected to the end cover. A cylindrical shaft is coaxially and fixedly connected inside each of the two end covers. One cylindrical shaft is coaxially and fixedly connected to the output end of a motor, and the other cylindrical shaft is coaxially and rotatably connected to the output end of a magnetic system adjustment device.

[0014] In the aforementioned iron removal beneficiation machine, a discharge water pipe is fixedly connected to the top of the concentrate end, and a flushing hole is opened at the bottom of the discharge water pipe. The flushing hole points to the drum on the concentrate end, and one end of the discharge water pipe is connected to the output end of an external water supply source.

[0015] Compared with existing technologies, the advantages of this invention are: 1. This invention, by setting a stepped structure, with the overall depth of the stepped structure increasing and then decreasing from the inlet end to the outlet end, can perform preliminary treatment of the slurry fluid in the initial stage, provide enhanced disturbance effect in the secondary enhancement stage, and ensure smooth flow of slurry in the final transition stage, thereby optimizing the separation effect and achieving higher separation efficiency.

[0016] 2. This invention utilizes adjustable baffles. The adjustable baffle between the front end and step I slows down the flow velocity of the falling slurry, preventing excessively high initial flow velocity from causing turbulence and ensuring uniform inflow of the slurry. This reduces the impact of uneven initial slurry distribution on the separation effect. The adjustable baffle in the intermediate enhancement stage is a relatively long baffle, ensuring the overall stability of the baffle and increasing the residence time of the slurry. This ensures that the slurry can be fully separated by the iron removal mechanism during the intermediate enhancement stage, achieving higher separation efficiency.

[0017] 3. This invention sets up protrusions. In the initial stage, there are fewer protrusions, which mainly guide the flow of slurry. In the middle stage, there are more protrusions, which provide enhanced disturbance. In the final transition stage, there are a moderate number of protrusions to ensure smooth flow. When the slurry flows through, it will generate local disturbances around the protrusions, which will increase the contact effect between the magnetic material and the magnetic field and improve the separation efficiency. At the same time, it effectively prevents the slurry from forming dead corners or stagnation in certain areas. Attached Figure Description

The stepped structure is connected between the front section and the rear section. The overall depth of the stepped structure increases and then decreases from the inlet end to the outlet end.

[0021] Reference Figures 4-6 The stepped structure includes steps I, II, III, IV, V, and VI. Steps I and II are the initial stage, steps III and IV are the intermediate enhancement stage, and steps V and VI are the final transition stage.

[0022] Adjustable baffles 42, multiple adjustable baffles 42 are connected between the front section and the stepped structure and at the depth inflection point of the stepped structure.

[0023] Multiple adjusting baffles 42 are fixedly connected between the front section and step I, and between step III and step IV.

[0024] The adjusting baffle 42 has a height-extendable structure.

[0025] Protrusion 43, multiple protrusions 43 connected to the stepped structure.

[0026] Multiple protrusions 43 connected to each step are evenly spaced, wherein the number of protrusions 43 in the late transition stage is less than the number of protrusions 43 in the intermediate enhancement stage, but greater than the number of protrusions 43 in the initial stage.

[0027] Protrusion 43 has a semi-circular structure.

[0028] The feeding assembly is connected to the top of the inlet end of the tank 4, and the output end of the feeding assembly points into the inlet end of the tank 4.

[0029] The feeding assembly includes a feed box 1, which is fixedly connected to the top of the tank 4. A water spray pipe 41 is connected to the bottom of the feed box 1. Multiple feed ports are opened on one side of the water spray pipe 41, and the output direction of the multiple feed ports is pointing towards the inlet end of the tank 4. One end of the water spray pipe 41 is connected to the output end of an external water supply source.

[0030] Reference Figures 7-9 The iron removal mechanism is connected to the tank 4. The input end of the iron removal mechanism extends into the tank 4, and the outlet end of the tank 4 is connected to the concentrate end 8. The output end of the iron removal mechanism points to the concentrate end 8. The iron removal mechanism is used to magnetically attract magnetic materials in the slurry in the tank 4 and transport them to the concentrate end 8.

[0031] The iron removal mechanism includes a motor 2, a motor base fixedly connected to a bracket 6, the motor 2 is mounted on the motor base, and a roller 3 is coaxially fixedly connected to the output end of the motor 2. The bottom of the roller 3 is in clearance fit with the bottom of the tank 4. A magnetic system 33 is provided in the gap at the bottom of the roller 3. A mounting frame is installed on the bracket 6 at the end away from the motor base. A magnetic system adjustment device 5 is connected to the mounting frame.

This facilitates the adjustment of the angle of the magnetic system 33. By adjusting the length of the connecting shaft, the position of the magnetic system 33 can be easily adjusted, thereby adjusting the angle and position of the magnetic system 33 for use.

[0034] The roller 3 includes an end cover 31, a cylinder body, and a cylindrical shaft 32. Both ends of the cylinder body are coaxially fixedly connected to the end cover 31.

One cylindrical shaft 32 is coaxially fixedly connected to the output end of the motor 2, and the other cylindrical shaft 32 is coaxially rotatably connected to the output end of the magnetic system adjustment device 5.

[0035] Tailings pipe 7 has a stepped structure and a tailings hole between the rear section and the tailings pipe 7. Tailings pipe 7 is connected to the bottom of the tailings hole.

[0036] A ore discharge water pipe 44 is fixedly connected to the top of the concentrate end 8. A flushing hole is opened at the bottom of the ore discharge water pipe 44, which points to the roller 3 on the concentrate end 8. One end of the ore discharge water pipe 44 is connected to the output end of an external water supply source.

[0037] In this invention, the slurry enters the tank 4 through the feed box 1, and the external water supply works to supply water to the water spray pipe 41 at its output end. The slurry and the water sprayed from the water spray pipe 41 enter the inlet end of the tank 4 together. When the slurry fluid first enters the tank 4, it will pass through a certain height, thus entering the front end of the tank 4 at a higher flow rate. The slurry fluid will be rapidly dispersed and initially separated into coarse particles by impact with the front end of the tank 4. The slurry fluid then encounters the regulating baffle 42 between the front end and step I, and is intercepted by the regulating baffle 42. Five regulating baffles 42 are set according to the length of the tank 4. The height of the regulating baffle 42 is changed according to the required flow rate to change the cross-sectional area of ​​the flow channel and the flow path of the fluid, thereby controlling the flow rate of the slurry fluid. It can also force the slurry fluid to change its path, thereby slowing down the flow rate and making the flow rate of the high-velocity slurry fluid moderate, avoiding the turbulence caused by the initial high flow rate of the slurry fluid, ensuring that the slurry fluid flows in evenly, and reducing the impact of the uneven distribution of the initial slurry fluid on the separation effect. The regulating baffle 42 set between the front end and step I helps the slurry fluid reach the optimal flow conditions before entering the sorting area, providing a good foundation for subsequent sorting; The regulating baffle 42 set in the intermediate enhancement stage is a relatively long regulating baffle 42, which ensures the overall stability of the regulating baffle 42, increases the residence time of the slurry fluid, and ensures that the slurry fluid can be fully separated by the iron removal mechanism when passing through the intermediate enhancement stage, so as to achieve higher separation efficiency. The stepped structure at the bottom of the tank 4 has an overall depth that increases from the inlet end to the outlet end. This allows for preliminary treatment of the slurry fluid in the initial stage, provides enhanced disturbance in the secondary stage, and ensures smooth slurry outflow in the final transition stage, thereby optimizing the sorting effect. Specifically, the dimensions are allocated based on the 1600mm long tank 4. Step I and Step II are the initial stages, with the depth gradually increasing. They are used to initially distribute the slurry and guide the flow direction. Step I: length 300mm, height 25mm; Step II: length 300mm, height 30mm. Steps III and IV are the intermediate enhancement stages. Starting from step III, the depth is reduced so that step IV can hinder the slurry flow, providing an enhanced disturbance effect and improving the separation efficiency. Step III: length 300mm, height 35mm; Step IV: length 300mm, height 40mm. Steps V and VI are the final transitional stages. The depth of steps V and VI continues to gradually increase, making the slurry flow smoother and ensuring smooth slurry outflow. Step V: length 200mm, height 35mm; Step VI: length 200mm, height 30mm. At the same time, the length of steps V and VI is reduced to facilitate the concentrated outflow of slurry, making the slurry flow more easily for sorting and discharge. The number and distribution of multiple protrusions 43 are controlled according to the function of each step, which helps to prevent the slurry from forming dead zones or stagnating in certain areas; The number and spacing of protrusions 43 are adjusted according to the length and height of each step to ensure optimal flow and disturbance effects. In the initial stage, fewer protrusions 43 are used to guide the slurry flow, with 6 protrusions 43 selected for step I and 8 for step II. In the intermediate enhancement stage, more protrusions 43 are used to enhance disturbance, with 10 protrusions 43 selected for step III and 12 for step IV. In the final transition stage, a moderate number of protrusions 43 are used to ensure smooth flow, with 7 protrusions 43 selected for step V and 6 for step VI. This design ensures that each step has an appropriate number of protrusions 43, preventing slurry stagnation and optimizing the sorting effect. Adjusting the number and distribution of protrusions 43 according to the function and design of each step can significantly improve the overall performance of the device. When the slurry flows through, it generates local disturbances around the protrusions 43. These disturbances disrupt the laminar flow of the slurry, enhance the mixing effect of the slurry, and increase the contact frequency and time between the slurry and the magnetic field of the magnetic system 33, thereby increasing the capture probability of magnetic materials. At the same time, the design of the protrusions 43 increases the flow complexity of the slurry, preventing the slurry from depositing at the bottom of the tank 4. The uniformly distributed protrusions 43 ensure that there is sufficient disturbance in each area of ​​the tank 4, reducing dead zones and the risk of blockage. The presence of the protrusions 43 makes the flow path of the slurry in the tank 4 longer, increases the contact area between the magnetic materials and the magnetic field, and improves the sorting efficiency. Under the magnetic force of the magnetic system 33, the magnetic mineral material is attracted to the outer surface of the bottom of the drum 3. When the motor 2 is working, its output end drives the end cover 31 and the drum body to rotate through the cylindrical shaft 32. When the drum 3 drives the magnetic mineral particles at its bottom to rotate to the outer area of ​​the magnetic system 33, the external water supply works and its output end supplies water to the unloading water pipe 44. The unloading water pipe 44 flushes water onto the drum 3 through the flushing hole. At this time, the magnetic mineral particles leave the magnetic system 33 with the drum 3. The magnetic attraction of the magnetic mineral particles is weakened, so they enter the concentrate end 8 under the impact of the water, completing the brushing of the magnetic mineral particles. The non-magnetic mineral particles flow into the tailings pipe 7 through the tailings hole.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
