Abstract
Description
Technical Field
[0001] This utility model belongs to the field of magnetic separator technology, and in particular relates to a permanent magnet drum magnetic separator with mechanical dispersion function. Background Technology
[0002] The permanent magnet drum separator is a highly efficient and energy-saving wet magnetic separation device, widely used in metallurgical mines, mineral processing plants, and other fields. It is mainly used to separate fine-particle magnetic minerals or remove magnetic impurities from non-magnetic minerals. During operation, the slurry is typically poured into the drum through the feed inlet, and then the rotating permanent magnet drum adsorbs the magnetic mineral particles onto its surface.
[0003] Existing permanent magnet drum separators lack a material distribution mechanism, which causes a buildup of slurry when it is poured into the drum, hindering the adsorption of magnetic mineral particles. Utility Model Content
[0004] The purpose of this utility model embodiment is to provide a permanent magnet drum magnetic separator with mechanical dispersion function, which aims to solve the problems mentioned in the background art.
[0005] This utility model embodiment is implemented as follows: a permanent magnet drum magnetic separator with mechanical dispersion function includes a magnetic separator body, on which a feeding channel is provided; and further includes:
[0006] The bulk material module includes a bulk material channel slidably installed on the top of the feeding channel, and a limiting platform for matching the bulk material channel is also provided on the top of the feeding channel. Two baffles are symmetrically arranged in the bulk material channel, and an adjustment unit for driving the two baffles to move in opposite directions at the same time is also provided on the feeding channel. Connecting rods are provided on two side walls along the sliding direction of the bulk material channel. Each connecting rod is slidably installed in a mounting frame provided on the feeding channel. A push plate is provided at the end of the connecting rod away from the bulk material channel, and several return springs are provided between the push plate and the mounting frame.
[0007] A reciprocating unit is disposed on the side wall of the feeding channel and is used to push the push plate to move linearly back and forth.
[0008] In a further technical solution, two sets of adjustment units are provided on the feeding channel. The two sets of adjustment units are respectively connected to two baffles. The adjustment unit includes a telescopic component installed on the feeding channel. The telescopic end of the telescopic component is connected to a connecting plate, and the bottom of the baffle is provided with a limiting slide that matches the connecting plate.
[0009] In a further technical solution, the telescopic component can be an electric telescopic rod or a hydraulic telescopic rod.
[0010] In a further technical solution, the reciprocating unit is provided in two sets, and the two sets of reciprocating units are respectively located at both ends of the bulk material channel; the reciprocating unit includes a mounting base installed on the feeding channel, a motor is installed on the mounting base, and a cam is installed on the output end of the motor. During the operation of the two motors, the two cams will intermittently abut against the push plate, and the two cams will not abut against the push plate at the same time.
[0011] In a further technical solution, the feeding channel is elongated and arranged radially along the body of the magnetic separator.
[0012] This utility model provides a permanent magnet drum magnetic separator with mechanical dispersion function. Initially, the adjusting unit is in a non-operating state, and the two baffles are in contact with each other. When slurry is poured into the distribution channel, it is blocked by the baffles and cannot fall into the feed channel. Then, the reciprocating unit is activated, which drives the push plate in a linear reciprocating motion. The push plate, via a connecting rod, drives the distribution channel to move synchronously, causing the distribution channel to oscillate back and forth, ensuring the slurry is evenly distributed within it. Then, the adjusting unit is controlled to move the two baffles away from each other, allowing the slurry to fall into the feed channel and then into the magnetic separator body for magnetic separation. This device achieves uniform material distribution, ensuring the slurry is evenly distributed inside the magnetic separator body, effectively improving the efficiency of magnetic separation.

Detailed Implementation
[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0019] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0020] like Figures 1-4 As shown, a permanent magnet drum magnetic separator with mechanical dispersion function is provided in one embodiment of this utility model, including a magnetic separator body 1, on which a feeding channel 11 is provided; and further including:
[0021] The bulk material module 2 includes a bulk material channel 21 slidably mounted on the top of the feeding channel 11, and a limiting platform 111 for matching the bulk material channel 21 is also provided on the top of the feeding channel 11. Two baffles 22 are symmetrically arranged in the bulk material channel 21, and an adjustment unit 3 is also provided on the feeding channel 11 for driving the two baffles 22 to move in opposite directions at the same time. Connecting rods 23 are provided on two side walls along the sliding direction of the bulk material channel 21. Each connecting rod 23 is slidably mounted in a mounting frame 112 provided on the feeding channel 11. A push plate 25 is provided at the end of the connecting rod 23 away from the bulk material channel 21, and a plurality of return springs 24 are provided between the push plate 25 and the mounting frame 112.
[0022] The reciprocating unit 4 is disposed on the side wall of the feeding channel 11 and is used to push the push plate 25 to move linearly back and forth.
[0023] In this embodiment of the invention, initially, the adjusting unit 3 is in a non-working state, and the two baffles 22 are in contact with each other. When slurry is poured into the material distribution channel 21, it is blocked by the baffles 22 and cannot fall into the feed channel 11. Then, the reciprocating unit 4 is activated, which pushes the push plate 25 in a linear reciprocating motion. The push plate 25, through the connecting rod 23, drives the material distribution channel 21 to move synchronously, causing the material distribution channel 21 to oscillate back and forth, thus ensuring the slurry is evenly distributed within it. Then, the adjusting unit 3 is controlled to operate, causing the two baffles 22 to move away from each other, allowing the slurry to fall into the feed channel 11 and then into the magnetic separator body 1 for magnetic separation.
[0024] like Figure 1 and Figure 2As shown, in a preferred embodiment of the present invention, two sets of adjustment units 3 are provided on the feeding channel 11. The two sets of adjustment units 3 are respectively connected to two baffles 22. The adjustment unit 3 includes a telescopic member 31 installed on the feeding channel 11. The telescopic end of the telescopic member 31 is connected to a connecting plate 32, and the bottom of the baffle 22 is provided with a limiting slide 221 that matches the connecting plate 32.
[0025] In this embodiment of the invention, the telescopic member 31 can be an electric telescopic rod or a hydraulic telescopic rod. During use, when both sets of adjustment units 3 have telescopic members 31 in a retracted state (i.e., non-working state), the two baffles 22 abut against each other, blocking the slurry poured into the bulk material channel 21. Furthermore, during the reciprocating swing of the bulk material channel 21, the connecting plate 32 slides along the limiting slide 221, without interfering with the movement of the bulk material channel 21. Simultaneously, the connecting plate 32 also acts on the baffle 22, limiting its position and preventing displacement during the swinging motion of the bulk material channel 21. When the telescopic member 31 is in an extended state (i.e., working state), the two telescopic members 31 can drive the two baffles 22 to move simultaneously in opposite directions via their corresponding connecting plates 32, allowing the slurry in the bulk material channel 21 to fall into the feed channel 11 and then be transported to the magnetic separator body 1 for magnetic separation.
[0026] like Figure 1 , Figure 2 and Figure 4 As shown, in a preferred embodiment of the present invention, the reciprocating unit 4 is provided in two sets, and the two sets of reciprocating units 4 are respectively provided at both ends of the bulk material channel 21; the reciprocating unit 4 includes a mounting base 41 installed on the feeding channel 11, a motor 42 is installed on the mounting base 41, and a cam 43 is installed at the output end of the motor 42. During the operation of the two motors 42, the two cams 43 will intermittently abut against the push plate 25, and the two cams 43 will not abut against the push plate 25 at the same time.
[0027] In this embodiment of the utility model, when in use, simply start the motor 42. The motor 42 will drive the cam 43 to rotate synchronously. During the rotation of the cam 43, its protruding end will periodically abut against the push plate 25 and push the push plate 25 to move away from the feed channel 11. The push plate 25 can drive the material distribution channel 21 to move synchronously through the connecting rod 23. When the cam 43 is disengaged from the push plate 25, the elastic force of the return spring 24 will cause the push plate 25 to return to its initial position. Through the cooperation of the cam 43 and the return spring 24, the material distribution channel 21 can be made to swing back and forth, thereby evenly distributing the slurry in the material distribution channel 21.
[0028] In a preferred embodiment of this utility model, the feed channel 11 is elongated and arranged radially along the magnetic separator body 1, so that the conveyed slurry can cover all areas of the internal magnetic separator cylinder.
[0029] Working principle: In the initial state, the telescopic components 31 are both in the retracted state, and the two baffles 22 abut against each other. At this time, the slurry poured into the material channel 21 will be blocked by the baffles 22. Simply start the motor 42, and the motor 42 will drive the cam 43 to rotate synchronously. During the rotation of the cam 43, its protruding end will periodically abut against the push plate 25 and push the push plate 25 to move away from the feed channel 11. The push plate 25 can drive the material channel 21 to move synchronously through the connecting rod 23. When the cam 43 disengages from the push plate 25, the elastic force of the return spring 24 will make the push plate 25 return to its initial position. Through the cooperation of the cam 43 and the return spring 24, the material channel 21 can be made to swing back and forth, thereby evenly distributing the slurry in the material channel 21. Then, the telescopic component 31 is controlled to extend. The two telescopic components 31 can drive the two baffles 22 to move in opposite directions at the same time through the corresponding connecting plate 32, so that the slurry in the bulk material channel 21 can fall into the feed channel 11 and then be transported to the magnetic separator body 1 for magnetic separation.
[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
