TECHNICAL FIELD

[0001] The application relates to the technical field of ore material scraping of a magnetic separator, in particular to a permanent-magnetic drum type magnetic separator facilitating ore material scraping. BACKGROUND

[0002] The permanent-magnetic drum type magnetic separator is a kind of equipment widely used in mining, metallurgy, chemical industry and other industries, and is mainly used for separating magnetic minerals from ore materials. However, with long-term use of the magnetic separator, minerals are prone to accumulate on the surface of the roller, especially some minerals with strong adhesion, which will affect the operation efficiency of the equipment and intensify the wear of the roller and the scraper, thereby reducing the service life of the equipment.

[0003] The conventional scraping mechanism of the magnetic separator is usually designed with a single scraper, and the scraping effect is limited, so it is difficult to achieve efficient and uniform mineral scraping, and the wear of the scraper is serious after long-term use.

[0004] Therefore, how to improve the scraping efficiency of the minerals, reduce the wear speed of the scraper and prolong the service life of the equipment has become an important challenge in the design of the magnetic separator. SUMMARY

[0005] In view of the above technical problems, the application solves the problem of limited effect and high wear of the single-layer scraper in the prior art.

[0006] In order to achieve the above purpose, the technical scheme adopted by the application is as follows: a permanent-magnetic drum type magnetic separator facilitating ore material scraping, comprising a base, a roller rotatably arranged on the base, a collecting groove and a collecting box fixedly arranged on the base, the collecting groove corresponding in position to the collecting box, a horizontal shaft slidably arranged on the collecting groove, a plurality of staggered arc-shaped plates slidably arranged on the horizontal shaft, a primary scraper fixedly arranged on the arc-shaped plate, a secondary scraper and a tertiary scraper slidably arranged on the arc-shaped plate, and an inclination angle existing between the primary scraper, the secondary scraper, the tertiary scraper and the arc-shaped plate.

[0007] In order to better achieve the application, further, a semicircular contact end is arranged on the primary scraper, an inclined surface is arranged on the secondary scraper, and an arc-shaped surface matched with the outer wall of the roller is arranged on the tertiary scraper.

[0008] In order to better achieve the application, further, six sliding rods are slidably arranged on the arc-shaped plate, one spring is fixedly arranged on each sliding rod, the spring is sleeved on the sliding rod, a buffer block is fixedly arranged on the spring, and the buffer block is fixedly arranged on the arc-shaped plate.

[0009] In order to better achieve the application, further, a horizontal plate is slidably arranged on the arc-shaped plate, an installation plate is fixedly arranged on the horizontal plate, and the installation plate is fixedly connected with the horizontal shaft.

[0010] In order to better realize the application, further, the base is fixedly provided with a side frame, the side frame is fixedly provided with a mounting groove, the mounting groove is provided with a sliding groove, a horizontal shaft is slidingly arranged on the sliding groove of the mounting groove, the side frame is provided with a vertical sliding groove, a limiting block is slidingly arranged on the sliding groove, the limiting block is fixedly provided with a lifting rod, the lifting rod is provided with a sliding groove, a convex shaft is arranged on the horizontal shaft, and the convex shaft is slidingly connected to the sliding groove of the lifting rod.

[0011] In order to better realize the application, further, the base is fixedly provided with a side frame, the side frame is fixedly provided with a mounting groove, the mounting groove is provided with a sliding groove, a horizontal shaft is slidingly arranged on the sliding groove of the mounting groove, the side frame is provided with a vertical sliding groove, a limiting block is slidingly arranged on the sliding groove, the limiting block is fixedly provided with a lifting rod, the lifting rod is provided with a sliding groove, a convex shaft is arranged on the horizontal shaft, and the convex shaft is slidingly connected to the sliding groove of the lifting rod.

[0012] The technical scheme provided by the application has the following beneficial effects compared with the prior art:

[0013] 1. The application adopts a multi-stage scraping mechanism composed of a first-stage scraper, a second-stage scraper and a third-stage scraper. The scrapers at different stages cooperate with each other to scrape the mineral layer in different thicknesses and adhesion degrees in layers. The first-stage scraper first senses the thickness of the adhered mineral on the roller, and when the mineral is thick, the first-stage scraper drives the second-stage scraper and the third-stage scraper to move under the push of the mineral, thereby realizing preliminary layering treatment of the mineral. Subsequently, the second-stage scraper and the third-stage scraper further scrape the mineral in turn, and the inclined tip of the second-stage scraper can efficiently scrape the residual mineral, and the arc surface on the third-stage scraper is in close contact with the outer surface of the roller, and can comprehensively scrape the surface of the roller. This multi-stage scraping mode significantly improves the scraping efficiency of the mineral on the roller, and effectively solves the problem that the traditional single scraper or simple scraping device cannot completely remove the mineral.

[0014] 2. The semicircular contact end of the first-stage scraper drives the second-stage scraper and the third-stage scraper to move under the push of the mineral, thereby avoiding long-time and high-intensity direct contact of the second-stage scraper and the third-stage scraper with the outer wall of the roller, reducing the wear rate of the scrapers, and when facing thick mineral, the mineral can be layered and scraped, thereby avoiding damage to the scrapers caused by thick mineral, and reducing the replacement frequency of the scrapers.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0022] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0023] like Figures 1 to 5 As shown, a permanent magnet drum magnetic separator for easy scraping of mineral materials includes a base 101, on which a roller 102 is rotatably mounted. A collection trough 103 and a collection box 104 are fixedly mounted on the base 101, with the collection trough 103 and collection box 104 corresponding in position. A horizontal shaft 117 is slidably mounted on the collection trough 103, and multiple staggered arc-shaped plates 118 are slidably mounted on the horizontal shaft 117. A primary scraper 119 is fixedly mounted on the arc-shaped plates 118, and a secondary scraper 120 and a tertiary scraper 121 are slidably mounted on the arc-shaped plates 118. The primary scraper 119, the secondary scraper 120, and the tertiary scraper 121 are all inclined at an angle to the arc-shaped plates 118.

[0024] Specifically, the first scraper 119, the second scraper 120 and the third scraper 121 are combined to form a multi-stage scraping mechanism, each stage has different functions, and together they achieve efficient scraping of the minerals on the roller of the magnetic separator. By setting the adjacent arc-shaped plates 118 in a staggered manner, the same level of scrapers on the adjacent arc-shaped plates 118 are also staggered, so that gaps are formed between the scrapers, and there is partial overlap between the left and right, thereby ensuring the integrity of the scraping interval and facilitating the movement of the scraped minerals along the inclined direction of the scrapers, falling through the gaps formed by the staggered arrangement, and being guided by the collecting groove 103 to fall into the collecting box 104 for collection.

[0025] As shown in Figure 5 the first scraper 119 is provided with a semicircular contact end, the second scraper 120 is provided with an inclined surface, and the third scraper 121 is provided with an arc surface matching the outer wall of the roller 102.

[0026] Specifically, the semicircular contact end of the first scraper 119 is mainly used to sense the thickness of the adhered minerals on the roller 102, so that the second scraper 120 and the third scraper 121 are moved by the arc-shaped plate 118 under the push of the minerals, thereby avoiding long-term and high-intensity contact between the second scraper 120 and the third scraper 121 and the outer wall of the roller 102, reducing the wear rate of the second scraper 120 and the third scraper 121, improving the service life of the equipment, and performing scraping work on the minerals layer by layer by adapting to the thickness, thereby avoiding that some minerals with high adhesion strength cannot be scraped in one go, and improving the scraping efficiency by scraping in multiple times and multiple layers.

[0027] The length of the first scraper 119 is less than that of the second scraper 120 and the third scraper 121, so that when the second scraper 120 and the third scraper 121 contact the roller 102, the first scraper 119 still maintains a certain distance from the roller 102. Only when the minerals on the roller 102 are thick, the first scraper 119 will contact the minerals and move the arc-shaped plate 118 by pushing the thick minerals. After the second scraper 120 and the third scraper 121 contact the roller 102, they will continue to move the arc-shaped plate 118 by a certain distance, so that the second scraper 120 and the third scraper 121 slide on the arc-shaped plate 118 by a certain distance, the second scraper 120 and the third scraper 121 respectively push the sliding rod 122 to slide on the arc-shaped plate 118, and stretch the spring 123, thereby ensuring the contact between the second scraper 120 and the third scraper 121 and the roller 102, and further improving the scraping effect of the minerals on the roller 102.

[0028] The arc surface on the third scraper 121 can be in close contact with the outer surface of the roller 102, so as to comprehensively scrape the surface of the roller 102; the inclined surface on the second scraper 120 is only in contact with the roller 102 through the tip, and the mineral is scraped through the tip, so as to improve the scraping effect; and the semicircular contact end of the first scraper 119 is only used for contacting the thicker mineral, and drives the second scraper 120 and the third scraper 121 to move away from the roller 102, so as to scrape the mineral in layers.

[0029] As shown in Figure 4 and Figure 5 , the arc-shaped plate 118 is slidably provided with six sliding rods 122, and each sliding rod 122 is fixedly provided with a spring 123, the spring 123 is sleeved on the sliding rod 122, the spring 123 is fixedly provided with a buffer block 124, and the buffer block 124 is fixedly provided on the arc-shaped plate 118.

[0030] Specifically, one sliding rod 122, spring 123 and buffer block 124 form a set of buffering mechanisms, and each second scraper 120 and third scraper 121 is respectively provided with three sets of sliding rods 122, springs 123 and buffer blocks 124, so as to improve the contact ability between the second scraper 120 and the third scraper 121 and the outer wall of the roller 102, so that when the mineral with high adhesion strength is encountered during scraping, the second scraper 120 and the third scraper 121 can be pushed to rebound, and when the mineral with low adhesion strength is encountered, the second scraper 120 and the third scraper 121 will not be pushed, that is, the range of adhesion strength of the mineral that can be scraped by the second scraper 120 and the third scraper 121 is improved, and the application ability is improved. At the same time, the second scraper 120 and the third scraper 121 avoid hard contact with the roller 102 due to the absence of buffering mechanisms, so that the friction is too large, and the roller 102 or the second scraper 120 and the third scraper 121 itself is damaged during scraping.

[0031] As shown in Figure 4 , the arc-shaped plate 118 is slidably provided with a horizontal plate 116, the horizontal plate 116 is fixedly provided with a mounting plate 113, and the mounting plate 113 is fixedly connected with the horizontal shaft 117.

[0032] Specifically, a plurality of arc-shaped plates 118 are fixedly connected with the horizontal shaft 117 and the horizontal plate 116, so that the arc-shaped plate 118 can stably approach or move away from the roller 102, and the shaking of the arc-shaped plate 118 during scraping is avoided, and the scraping effect is affected.

[0033] As shown in Figure 1 and Figure 2As shown, the base 101 is fixedly provided with a side frame 111, the side frame 111 is fixedly provided with a mounting groove 112, the mounting groove 112 is provided with a sliding groove, the horizontal shaft 117 is slidingly arranged on the sliding groove of the mounting groove 112, the side frame 111 is provided with a vertical sliding groove, the vertical sliding groove is slidingly provided with a limiting block 115, the limiting block 115 is fixedly provided with a lifting rod 114, the lifting rod 114 is provided with a sliding groove, the horizontal shaft 117 is provided with a convex shaft, and the convex shaft is slidingly connected to the sliding groove of the lifting rod 114.

[0034] Specifically, the base 101 is provided with two groups of side frames 111, mounting grooves 112, mounting plates 113, lifting rods 114 and limiting blocks 115. When scraping is needed, the lifting rod 114 is controlled to move downward, so that the limiting block 115 slides downward on the sliding groove of the side frame 111, the lifting rod 114 pulls the convex shaft of the mounting plate 113 through the sliding groove, so that the mounting plate 113 slides on the sliding groove of the mounting groove 112, and then the convex shaft of the mounting plate 113 slides transversely on the sliding groove of the lifting rod 114, so that the mounting plate 113 approaches the roller 102, and then the first scraper 119, the second scraper 120 and the third scraper 121 on the plurality of arc-shaped plates 118 are driven to contact the roller 102.

[0035] As shown in Figure 1 and Figure 3 The base 101 is fixedly provided with a cylinder 105, the output end of the cylinder 105 is fixedly provided with a lifting frame 106, the lifting frame 106 is slidingly provided with a pull rod 107, the pull rod 107 is fixedly provided with a connecting block 108, the connecting block 108 is slidingly provided with a horizontal rod 110, the horizontal rod 110 is fixedly connected with the lifting rod 114, the connecting block 108 is fixedly provided with a lifting spring 109, and the lifting spring 109 is also fixedly arranged on the lifting frame 106.

[0036] Specifically, the lifting spring 109 is sleeved on the pull rod 107. In use, the pull rod 107 is controlled to move up and down by the cylinder 105. In the initial state, because of the action of the mounting plate 113, a greater downward tension is generated on the connecting block 108 and the horizontal rod 110, and the lifting spring 109 tends to be stretched. Therefore, the lifting spring 109 adopts a specification with a larger elastic potential, so that the lifting spring 109 itself can overcome the tension of the connecting block 108 in the initial state, that is, the lifting spring 109 will not be stretched in the initial state, so that the pull rod 107, the connecting block 108, the lifting spring 109 and the horizontal rod 110 are kept in balance.

[0037] When the pull rod 107 moves upward, because the horizontal rod 110 needs to push the lifting rod 114, the lifting rod 114 pushes the mounting plate 113 to slide on the mounting groove 112, and a larger pushing force is needed, so that the pull rod 107 will stretch the lifting spring 109, and pull the connecting block 108, the horizontal rod 110 and the lifting rod 114 through the elastic force of the lifting spring 109; when it is needed to control the downward movement of the pull rod 107, the pull rod 107 first pushes the lifting spring 109 downward, and through the downward force of the mounting plate 113 and the lifting rod 114 itself, the mounting plate 113 is jointly slid on the mounting groove 112 to the direction close to the roller 102, so as to drive the arc-shaped plate 118 to close to the roller 102. When the mineral pushes the primary scraper 119 and the arc-shaped plate 118 to move during the scraping work, the arc-shaped plate 118 drives the mounting plate 113 to slide on the mounting groove 112 through the horizontal plate 116 and the horizontal shaft 117, and drives the lifting rod 114, the horizontal rod 110 and the connecting block 108 to move upward through the convex shaft of the mounting plate 113, so as to compress the lifting spring 109, and make the connecting block 108 slide on the pull rod 107, at this time, the elastic force of the lifting spring 109 buffers the pushing of the mineral, avoids that the primary scraper 119 moves too far, affects the scraping effect, and makes the primary scraper 119 can always keep the contact ability with the mineral.

[0038] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and variations. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application shall be included in the protection scope of the present application.
