Uniform material distribution equipment for facilitating magnetic separation of iron concentrate

Abstract

This utility model discloses a uniform material distribution device for facilitating magnetic separation of iron concentrate, including a support frame, a lifting component, and a cleaning component. The magnetic separator body is mounted on the top of the support frame, and a feed hopper is fixedly installed on the outer surface of the magnetic separator body. A vibrating screen plate mechanism is mounted on the inner surface of the top of the feed hopper. Four lifting components are mounted on the outer surface at the four corners of the feed hopper. By setting up the lifting component and cleaning component, the screen plate in the vibrating screen plate mechanism can be lifted by the lifting component during the interval of raw material feeding, so that its upper surface is flush with the feed hopper. At this time, by controlling the cleaning component, the scraper moves against the upper surface of the feed hopper and the vibrating screen plate mechanism, pushing the surface impurities towards the guide plate. Thus, the surface of the vibrating screen plate mechanism is cleaned during the interval of raw material feeding, which improves the overall operating efficiency.

Description

Technical Field

[0001] This utility model relates to the field of magnetic separation processing technology for iron concentrate, and more specifically, to a uniform material distribution device that facilitates magnetic separation processing of iron concentrate. Background Technology

[0002] Magnetic separation of iron ore concentrate is a process that extracts high-purity iron concentrate from iron ore using magnetic separation technology. The process first involves crushing and grinding the raw ore, then using a magnetic separator to separate iron-containing minerals from non-magnetic impurities under the influence of a magnetic field. The resulting iron concentrate has a high iron content and low impurities, making it suitable for steelmaking. This process is efficient and environmentally friendly, significantly improving the utilization rate of iron ore and product quality.

[0003] A search revealed CN219943692U, which discloses a magnetic separator for iron concentrate. The separator includes a main body, a feed box and a discharge box on one side, a fixed ring inside the feed box, a fixed ring above the fixed ring, and a screen on the fixed ring. A cooling box is located at the bottom of the main body, with cooling holes. A refrigeration unit is located on one side of the cooling box, and a dustproof screen is located at the air inlet of the refrigeration unit. A dust collection box is located at the top of the main body, with a dust collection pipe inside and a dust collection fan on one side of the dust collection pipe. The feed box, fixed ring, fixed ring, and screen facilitate filtering and screening of the iron concentrate raw material at the feed box, preventing impurities from clogging the screen and affecting the working efficiency of the main body. The cooling box, cooling holes, and refrigeration unit cool the interior of the main body. The dust collection box, dust collection pipe, and dust collection fan clean the dust generated during magnetic separation inside the main body.

[0004] However, this type of magnetic separator for iron concentrate still has some drawbacks. For example, the above-mentioned technical solution achieves the filtration and screening of iron concentrate raw materials by setting a screen at the feed box, and designs a structure that facilitates the disassembly of the screen to clean impurities. However, since cleaning the screen requires disassembly and pausing the equipment, the screening process is interrupted and cannot be operated continuously, thus reducing the overall screening efficiency of the equipment. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a uniform material distribution device that facilitates magnetic separation of iron concentrate, so as to solve the problem that in the prior art, some devices filter iron concentrate through screens, which is convenient for disassembly and cleaning, but requires machine shutdown during cleaning, resulting in reduced screening efficiency.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a uniform material distribution device for facilitating magnetic separation of iron concentrate, comprising...

[0007] A support frame is provided, on the top of which the main body of the magnetic separator is provided. A feed hopper is fixedly installed on the outer surface of the main body of the magnetic separator, and a vibrating screen plate mechanism is provided on the inner surface of the top of the feed hopper.

[0008] The lifting assembly has four lifting components on its outer surface at the four corners of the middle part of the feed hopper;

[0009] The cleaning assembly includes a limiting frame and a scraper. Two limiting frames are arranged parallel to each other on both sides of the top of the feed hopper along its length, and the surfaces of the sides closest to each other are fixedly installed to the outer surface of the feed hopper. A motor is fixedly installed at the end of the limiting frame, and a lead screw is fixedly sleeved at the output end of the motor. The surfaces at both ends of the lead screw are rotatably installed to the inner surfaces at both ends of the limiting frame, and the outer surfaces are threadedly connected to sliders. The outer surface of the bottom of the sliders is slidably installed to the inner surface of the limiting frame. The surfaces of the tops of the two sliders that are close to each other are fixedly installed to the two ends of the scraper, and the lower surface of the scraper is in contact with the upper surface of the feed hopper.

[0010] The lifting assembly includes an electric telescopic rod, a fixing block is fixedly installed on the outer surface of the bottom of the electric telescopic rod, the surface of the fixing block is fixedly installed on the outer surface of the feed hopper, the outer surface of the top of the electric telescopic rod is slidably installed on the inner surface of the side wall of the feed hopper, and a protruding post is fixedly installed on the top of the electric telescopic rod, and the upper surface of the protruding post is in contact with the lower surface of the vibrating screen plate mechanism.

[0011] The device also includes a guide plate, a support column, and a fabric assembly. The guide plate is located on the side of the top of the feed hopper in the width direction away from the limiting frame. The fabric assembly is located on the side of the top of the feed hopper in the width direction close to the limiting frame. The bottom of the support column is fixedly installed to the upper surface of the support frame, and the top is fixedly installed to the lower surface of the guide plate.

[0012] The fabric assembly includes a second support column, a gear, and a second electric telescopic rod. The bottom of the second support column is fixedly installed on the upper surface of the support frame. A roller is rotatably installed on the inner surface of the top of the second support column. A U-shaped frame is fixedly installed at one end of the roller, and a toothed ring is fixedly sleeved on the outer surface of the other end. Three fabric hoppers are arranged in parallel inside the U-shaped frame, and the outer surfaces of the tops of the three fabric hoppers are fixedly installed on the inner surface of the U-shaped frame. A shaft is rotatably installed in the middle of the gear, and the end of the shaft is fixedly installed on the outer surface of the second support column. The toothed ring meshes with the gear. The side edge of the second electric telescopic rod is fixedly installed on the outer surface of the second support column, and a rack is fixedly installed at the end of the second electric telescopic rod. The rack meshes with the gear.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In the above scheme, by setting up lifting components and cleaning components, after the vibrating screen plate mechanism screens the feed material for a period of time, the operator can use the lifting components to lift the screen plate in the vibrating screen plate mechanism during the interval between raw material feeding. This will make its upper surface flush with the feed hopper. At this time, the motor is started, and the lead screw fixedly connected to the motor output end rotates inside the limit frame, pulling the slider connected to the outer surface threaded laterally. The scraper connected in the middle of the two sliders is driven to move against the feed hopper and the upper surface of the vibrating screen plate mechanism, pushing the surface impurities towards the guide plate and sliding them from the surface of the guide plate into the collection box. Afterward, the scraper and lifting components return to their original positions, and the operator adds raw material to the top of the vibrating screen plate mechanism. This utilizes the interval between raw material feeding to clean the surface of the vibrating screen plate mechanism, which helps to improve the overall work efficiency.

[0015] In the above scheme, by setting up a feeding assembly, when the iron concentrate is fed into the magnetic separator for magnetic separation, the operator can first put the raw material into the feeding hopper. At the same time, the electric telescopic rod 2 is controlled to continuously extend and retract. The rack fixedly installed at the end of the electric telescopic rod 2 is pulled to move laterally back and forth, driving the meshing gear to rotate back and forth. This causes the gear ring meshing with the gear to rotate back and forth synchronously, driving the connected shaft roller and the return frame installed at the end of the shaft roller to rotate back and forth. The feeding hopper set inside the return frame swings left and right. During the swinging process, the feeding hopper drives the raw material inside to be evenly sprinkled above the vibrating screen plate mechanism, which makes it easier to distribute the raw material more evenly on the top of the vibrating screen plate mechanism, reducing the accumulation of raw material and improving the actual feeding efficiency.

[0022] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0023] As attached Figure 1 To be continued Figure 4 An embodiment of this utility model provides a uniform material distribution device for facilitating magnetic separation of iron concentrate, including...

[0024] Support frame 1, magnetic separator body 2 is set on the top of support frame 1, feed hopper 3 is fixedly installed on the outer surface of magnetic separator body 2, and vibrating screen plate mechanism 4 is set on the inner surface of the top of feed hopper 3.

[0025] By setting up a vibrating screen plate mechanism 4, the outer edge of the screen plate in the vibrating screen plate mechanism 4 is movably installed with the inner wall of the top of the feed hopper 3, and a vibrating motor is installed on the surface. It is connected to the surface of the feed hopper 3 by a spring, which facilitates the screen plate to vibrate and screen the material. When the cleaning component 6 cleans the impurities on the surface of the screen plate, the vibrating motor can be briefly stopped to ensure stable cleaning of impurities.

[0026] The lifting assembly 5 has four parts on the outer surface at the four corners of the middle part of the feed hopper 3;

[0027] Cleaning component 6 includes a limiting frame 60 and a scraper 64. Two limiting frames 60 are arranged parallel to each other on both sides of the top of the feed hopper 3 along its length, and the surfaces of the sides that are close to each other are fixedly installed with the outer surface of the feed hopper 3. A motor 61 is fixedly installed at the end of the limiting frame 60. A lead screw 62 is fixedly sleeved at the output end of the motor 61. The surfaces of both ends of the lead screw 62 are rotatably installed with the inner surfaces of both ends of the limiting frame 60, and the outer surface of the lead screw 62 is threadedly connected with a slider 63. The outer surface of the bottom of the slider 63 is slidably installed with the inner surface of the limiting frame 60. The surfaces of the tops of the two sliders 63 that are close to each other are fixedly installed with the two ends of the scraper 64, and the lower surface of the scraper 64 is in contact with the upper surface of the feed hopper 3.

[0028] The lifting assembly 5 includes an electric telescopic rod 50. A fixing block 51 is fixedly installed on the outer surface of the bottom of the electric telescopic rod 50. The surface of the fixing block 51 is fixedly installed with the outer surface of the feed hopper 3.

A protruding post 52 is fixedly installed on the top of the electric telescopic rod 50, and the upper surface of the protruding post 52 is in contact with the lower surface of the vibrating screen plate mechanism 4.

[0029] By setting the lifting component 5, the electric telescopic rod 50 is initially in a retracted state, and the protrusion 52 at its top is located in the inner cavity of the feed hopper 3. After the electric telescopic rod 50 is extended, its end will move upward along the inner surface of the feed hopper 3. The protrusion 52 abuts against the lower surface of the screen plate at the four corners of the vibrating screen plate mechanism 4, and gradually lifts the screen plate of the vibrating screen plate mechanism 4 upward to move the upper surface to be flush with the upper surface of the feed hopper 3.

[0030] It also includes a guide plate 7, a support column 8, and a fabric assembly 9. The guide plate 7 is located on the side of the top of the feed hopper 3 in the width direction away from the limit frame 60. The fabric assembly 9 is located on the side of the top of the feed hopper 3 in the width direction close to the limit frame 60. The bottom of the support column 8 is fixedly installed on the upper surface of the support frame 1, and the top is fixedly installed on the lower surface of the guide plate 7.

[0031] The fabric assembly 9 includes a second support column 90, a gear 95, and an electric telescopic rod 97. The bottom of the second support column 90 is fixedly installed on the upper surface of the support frame 1. A roller 91 is rotatably installed on the inner surface of the top of the second support column 90. A U-shaped frame 92 is fixedly installed at one end of the roller 91, and a toothed ring 94 is fixedly sleeved on the outer surface of the other end. Three fabric hoppers 93 are arranged in parallel inside the U-shaped frame 92, and the outer surfaces of the tops of the three fabric hoppers 93 are fixedly installed on the inner surface of the U-shaped frame 92.

A rack 96 is fixedly installed at the end of the electric telescopic rod 97, and the rack 96 meshes with the gear 95.

[0032] By setting a rack 96, the middle part of the rack 96 is connected to the end of the pre-electric telescopic rod 97 of the connecting plate, and the outer surface of the side end of the connecting plate is slidably installed with the inner surface of the support column 90, thereby improving the stability of the rack 96 movement.

[0033] The working process of this utility model is as follows:

[0034] When iron concentrate is fed into the main body 2 of the magnetic separator for magnetic separation, the operator can first put the raw material into the feeding hopper 93. At the same time, the electric telescopic rod 97 is continuously extended and retracted. The rack 96, which is fixedly installed at the end of the electric telescopic rod 97, is pulled to move laterally back and forth, driving the meshing gear 95 to rotate back and forth. This causes the toothed ring 94, which meshes with the gear 95, to also rotate back and forth synchronously. This drives the connected shaft roller 91 and the return frame 92 installed at the end of the shaft roller 91 to rotate back and forth. The feeding hopper 93, which is set inside the return frame 92, swings left and right. During the swinging process, the feeding hopper 93 causes the raw material inside to be evenly sprinkled on the top of the vibrating screen plate mechanism 4, which makes it easier to distribute the raw material more evenly on the top of the vibrating screen plate mechanism 4, reducing the accumulation of raw material and improving the actual feeding efficiency.

[0035] After the vibrating screen plate mechanism 4 screens the feed material for a period of time, the operator can use the lifting component 5 to lift the screen plate in the vibrating screen plate mechanism 4 during the interval between material feeding. The upper surface of the screen plate is then flush with the feed hopper 3. At this time, the motor 61 is started, and the lead screw 62, which is fixedly sleeved with the output end of the motor 61, rotates inside the limit frame 60. This pulls the slider 63, which is threaded on the outer surface, to move laterally. The scraper 64, which is connected in the middle of the two sliders 63, is driven to move against the upper surface of the feed hopper 3 and the vibrating screen plate mechanism 4, pushing the impurities on the surface towards the guide plate 7 and allowing them to slide off the surface of the guide plate 7 into the collection box. Afterward, the scraper 64 and the lifting component 5 return to their original positions, and the operator adds the raw material to the top of the vibrating screen plate mechanism 4. This allows the operator to clean the surface of the vibrating screen plate mechanism 4 during the interval between material feeding, thus improving the overall work efficiency.
