Description
Technical Field
The invention relates to a conveyor, in particular to a magnetic relay separation conveyor.
Background
The belt conveyor is the most important bulk material conveying and loading and unloading equipment, can be widely applied to the industrial fields of mines, metallurgy, and the like, and can be widely applied to coal mines, iron and steel enterprises, ports, cement plants, and the like. However, the conventional belt conveyor is conveyed by means of friction force between the belt and the materials and between the material particles, so that the belt conveyor cannot realize large-angle or even vertical-angle material conveying. In addition, the existing belt conveyor often has no selectivity to materials, for example, a magnetic separator is generally adopted to separate the magnetically permeable material from the non-magnetically permeable material for the mixture of the magnetically permeable material and the non-magnetically permeable material, and then the belt conveyor is used for conveying the materials.
Disclosure of Invention
Aiming at the defects of the prior art, the invention provides a magnetic relay separation conveyor which can realize separation of magnetic conductive materials and non-magnetic conductive materials and long-distance conveying of vertical angles and other angles of magnetic conductive powdery materials.
The technical scheme of the invention is as follows: the magnetic relay separation conveyor comprises a plurality of magnetic rollers which are arranged in parallel at intervals and a collecting device for collecting materials from the magnetic rollers, wherein each magnetic roller comprises a roller and a plurality of magnetic rings which are arranged in the roller and synchronously rotate with the roller, the magnetic rings are arranged at intervals along the axial direction of the magnetic roller, the magnetic pole directions of the magnetic rings are radial, the polar directions of two adjacent magnetic rings are the same, the polar directions of the magnetic rings on the two adjacent magnetic rollers are opposite, and the magnetic field intensity of the surfaces of the rollers of the two adjacent magnetic rollers is the same.
The invention firstly utilizes the adsorption effect of the magnetic roller on the magnetic conductive material, can be used for separating and conveying the magnetic conductive material and the non-magnetic conductive material, and secondly utilizes the homopolar repulsion generated by homopolar polarities of adjacent magnetic rings on the same magnetic roller, and the opposite repulsion effect of the magnetic rings which are opposite to each other on the adjacent magnetic roller can ensure that the magnetic conductive material is piled up on one magnetic roller and extends along the normal direction on the surface of the magnetic roller to form a radial needle group. The radial needle group of the next magnetic roller is continuously extended (the extension length is determined according to the magnetic field intensity), part of the magnetic conduction material is attracted by the previous magnetic roller through the rotation of the magnetic roller, and the magnetic roller is left on the surface of the magnetic roller to finish the transmission between the two magnetic rollers. The next magnetic roller continuously attracts the magnetic conductive material from the raw material pile and transmits the magnetic conductive material to the previous magnetic roller, and the corresponding number of the magnetic rollers is set according to the required transmission distance.
Further, in order to prevent the magnetic conduction material from excessively accumulating on a single magnetic roller, the magnetic conduction material is blocked between adjacent magnetic rollers, and the surface linear speeds of the adjacent magnetic rollers are within 10 percent.
Preferably, the surface linear velocities of the adjacent magnetic rollers are equal.
Further, in order to enable the magnetic conduction material accumulated on the surface of the next magnetic roller to be in full time contact with the previous magnetic roller, the energy consumption of the same conveying amount is reduced, and the rotation directions of the adjacent magnetic rollers are opposite.
Furthermore, in order to enhance the stacking extension of the magnetic conductive materials on the same magnetic roller along the normal direction of the roller surface, the magnetic ring comprises a plurality of magnetic blocks which are arranged at equal intervals along the circumferential direction of the roller.
Furthermore, the magnetic blocks forming two adjacent magnetic rings on the same magnetic roller are coaxially arranged. That is, the magnetic blocks of the adjacent magnetic rings are arranged in parallel in the axial direction of the magnetic roller, and the gaps between the magnetic blocks of the adjacent magnetic rings are also arranged in parallel in the axial direction of the magnetic roller.
Further, in order to separate the magnetic conduction material from the final magnetic roller, the collection of the magnetic conduction material after the transportation is completed, and the collection device comprises a non-magnetic roller and a conveyer belt wound around the non-magnetic roller and the magnetic roller. When the magnetic conductive material is adsorbed on the surface of the conveyer belt due to the action of the final magnetic roller, the magnetic conductive material gradually breaks away from the attraction of the final magnetic roller along with the movement of the conveyer belt. When the magnetic material reaches the nonmagnetic roller, the magnetic material falls off along with the overturning of the conveying belt.
Furthermore, in order to smoothly bring the magnetic conductive material away from the attraction of the final magnetic roller, the surface of the conveying belt is provided with a concave-convex structure.
Preferably, the concave-convex structure is a groove and a convex strip arranged along the width direction of the conveying belt.
Furthermore, in order to separate the magnetic conduction material from the final magnetic roller, the collection device can also be a scraper blade, and the scraper blade forms a scraping effect on the surface of the magnetic roller.
The technical scheme provided by the invention has the advantages that:
the separation and conveying of the magnetic conductive material and the non-magnetic conductive material can be synchronously carried out through the magnetic effect adsorption conveying, such as the separation conveying of the iron powder mixed with lime dust, the conveying of the iron sand for polishing, the magnetic concentrate powder, the turning scrap iron and the like, and the separation conveying of the iron sand and the liquid, such as turning cooling liquid, surface processing buffer solution and the like, can be realized, and the separation is not needed to be carried out by a magnetic separator first, then the conveying is carried by a belt conveyor, so that the equipment structure is simplified.
Meanwhile, the principle of like-pole repulsion and opposite-pole attraction is adopted, and the magnetic conduction materials are conveyed among the magnetic rollers with the same magnetic field strength through rotation among the magnetic rollers, so that on one hand, the conveying can be realized by the same magnetic field strength, the step-by-step increase is not needed, the long-distance material conveying can be realized, and the conveying distance is limited by the limitation of the magnetic field strength in the prior art; on the other hand, the magnetic relay type conveying device is used for conveying at intervals, a connecting structure such as a conveying belt is not required to be arranged in the middle, conveying at any angle can be realized, and especially vertical angle conveying which cannot be completed by belt conveying can be realized. The equipment has the advantages of small abrasion, convenient maintenance, long-time reliable operation and high efficiency.

Detailed Description
The invention is further illustrated, but is not limited, by the following examples.
As shown in fig. 1 and 2, the magnetic relay separating conveyor according to the present embodiment includes a plurality of magnetic rollers 1 arranged in parallel and spaced apart, the magnetic rollers 1 may be driven by a motor, and rotation between the magnetic rollers 1 and the magnetic rollers 1 may be driven by cooperation of a belt pulley 2 and a belt 3, or may be driven by a gear or a sprocket in a driving manner. The diameters of the different magnetic rollers 1 may be different, but the surface linear velocity difference of the adjacent magnetic rollers 1 should be controlled within 10%. The present embodiment employs the magnet roller 1 of the same diameter, and the surface linear velocity of the magnet roller 1 is the same but the rotation directions are opposite. The relative positions of the magnetic rollers 1 can be arranged according to specific conveying requirements, and are sequentially arranged in the vertical direction, or obliquely arranged at a certain inclination angle, or the first two stages are arranged at a certain angle and the second two stages are arranged at another different angle. It should be noted that the magnetic relay separating conveyor structure of only one of the three magnetic rollers 1 is shown in fig. 1 and 2, and that the number of the magnetic rollers 1 should be determined according to the transmission distance, i.e., the set magnetic field strength, without being limited to the three magnetic rollers 1 in practical use. The collecting device is arranged at the tail end of the final magnetic roller 1 as relay conveying and comprises a non-magnetic roller 4 which is arranged in parallel with the final magnetic roller 1, a conveying belt 5 is wound on the non-magnetic roller 4 and the final magnetic roller 1, and the conveying belt 5 is used for conveying magnetic conductive powder materials away from the final magnetic roller. The surface of the conveyer belt 5 is provided with a concave-convex structure, and the concave-convex structure is a groove 6 and a convex strip 7 which are arranged along the width direction of the conveyer belt 5. When the conveyer belt 5 rotates continuously, the side wall of the raised strip 7 pushes the magnetic conductive powder material to move forwards, and gradually breaks away from the attraction of the final magnetic roller 1. When reaching the nonmagnetic roller 4, the magnetically permeable material falls off as the conveyor belt 5 turns over. With reference to fig. 3, it is easy to understand that the task of the collecting device is to remove the magnetically conductive material from the surface of the final magnetic roller 1, so that the collecting device may be formed by a scraper 8 opposite to the rotation direction of the magnetic roller 1, and the scraper 8 forms a scraping action on the surface of the magnetic roller 1 to scrape the magnetically conductive material away from the magnetic roller 1 as the magnetic roller 1 rotates.
As shown in fig. 4, the magnetic roller 1 includes a roller 9 and a plurality of magnetic rings 10 which are arranged in the roller 9 and rotate synchronously with the roller 9, the magnetic rings 10 are arranged at intervals along the axial direction of the magnetic roller 1, the magnetic pole directions of the magnetic rings 10 are radial, the polarity directions of two adjacent magnetic rings 10 are the same, the polarity directions of the two magnetic rings 10 on the two adjacent magnetic rollers 1 are opposite, namely, the outer ring of each magnetic ring 10 on the next magnetic roller 1a is S-polarity, the inner ring is N-polarity, the outer ring of each magnetic ring 10 on the last magnetic roller 1b is N-polarity, the inner ring is S-polarity, the outer ring of each magnetic ring on the last magnetic roller is S-polarity, the inner ring is N-polarity, and so on. As shown in fig. 5, the magnetic ring 10 may not be a complete ring magnet, and the magnetic ring 10 is formed by a plurality of magnetic blocks 11 equally spaced along the circumferential direction of the roller 9, and the magnetic blocks 11 forming two adjacent magnetic rings 10 on the same magnetic roller 1 are coaxially arranged, that is, the magnetic blocks 11 are arranged in a plurality of parallel columns in the axial direction of the magnetic roller 1. The polarity direction of each magnet 11 is the radial direction of the magnet roller 1, and the polarities pointing to the axis of the magnet roller 1 are the same. The magnetic rings 10 and the magnetic blocks 11 can be permanent magnets or electromagnets, but the magnetism of the magnetic rings 10 and the magnetic blocks 11 is controlled so that the magnetic field intensity of the roller surfaces of two adjacent magnetic rollers 1 is the same.
As shown in fig. 6, when the magnetic relay separation conveyor conveys the magnetic conductive powder material 12, the first stage magnetic roller 1a adsorbs the magnetic conductive powder material 11, and if the magnetic conductive powder material 11 is mixed with the non-magnetic conductive material, separation can be achieved by the present stage adsorption. On the first magnet roller 1a, a magnetic conductive material extends between two adjacent magnet rings 10 or magnet blocks along the normal direction on the surface of the magnet roller 1a to form a radial needle group. As the stack of magnetically permeable powder material 12 on the first magnet roller 1a expands, the upper magnet roller 1b attracts magnetically permeable powder material 122 and migrates from the next magnet roller 1a to the upper magnet roller 1b until the last magnet roller.
