Description

Technical Field

[0001] The utility model relates to the technical field of magnetic separation equipment, in particular to a drum type permanent magnetic separator. Background Art

[0002] Corundum is an oxide mineral with colors such as colorless, gray, yellow-gray, blue, etc., Mohs hardness of 9, transparent or translucent, and glassy luster. Corundum has the characteristics of high hardness, high melting point, and corrosion resistance. It is widely used in various industrial fields in the form of complex materials and also has certain ornamental value. In the process of corundum processing, it is necessary to separate the metal materials mixed in the corundum material, and the corundum material and metal materials are separated by using a magnetic separator.

[0003] For example, the patent document with the announcement number CN219400544U discloses a dry drum permanent magnetic separator. In the prior art, most of the materials are put into the feed hopper, and the materials fall directly onto the magnetic separation drum. The non-magnetic materials fall directly downward into the collection hopper. The permanent magnetic block in the magnetic separation drum is used to make the metal material be adsorbed on the magnetic separation drum and rotate with the magnetic separation drum. When the material leaves the permanent magnetic block, the metal material automatically falls off, thereby separating the material and the metal material.

[0004] However, in the prior art, materials are usually poured directly into a feed hopper, and then fall directly onto the magnetic separation drum. Usually, the materials cannot be evenly distributed in the feed hopper, so that the materials fall unevenly on the magnetic separation drum, and the falling speed of the materials is fast, and the contact time between the materials and the magnetic separation drum is short. Therefore, the magnetic separation effect in the area with more materials on the magnetic separation drum is not ideal, and the metal material may be discharged together with part of the material due to the large amount of materials in this area.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] The utility model is further described below in conjunction with the accompanying drawings:

[0026] like Figure 1-Figure 6 As shown, a drum-type permanent magnetic separator includes a casing 1, a feed pipe 2 is fixedly connected to the top of the casing 1, a feed hopper 3 is fixedly connected to the top of the feed pipe 2, a magnetic separation mechanism is arranged inside the casing 1, and the magnetic separation mechanism includes a motor 801, the motor 801 is connected to one side of the casing 1 by screws, a magnetic separation drum 802 is rotatably connected inside the casing 1, the feed pipe 2 is located above and at the rear of the magnetic separation drum 802, the output shaft of the motor 801 is fixedly connected to the magnetic separation drum 802, and the end of the magnetic separation drum 802 away from the motor 801 is fixedly connected to a connecting shaft 803, and the connecting shaft 803 is fixedly connected to the magnetic separation drum 802. 03 extends out of the casing 1, and the connecting shaft 803 is connected to the casing 1 through a bearing. A magnetic hopper 804 and a material hopper 805 are fixedly connected to the bottom of the casing 1. The magnetic hopper 804 is located in front of the material hopper 805. The corundum material passes through the feed hopper 3 and the feed pipe 2 and falls onto the magnetic separation cylinder 802. The magnetic separation cylinder 802 adsorbs the metal material, and the corundum material directly falls into the material hopper 805 along the connecting shaft 803. The metal material moves with the magnetic separation cylinder 802. When the metal material moves to the top of the magnetic hopper 804, the metal material separates from the magnetic separation cylinder 802 and falls into the magnetic hopper 804.

[0027] A bulking mechanism is provided inside the feed pipe 2, and the bulking mechanism is used to make the corundum material fall evenly onto the magnetic separation cylinder 802. The bulking mechanism includes a bulking shaft 401, and the bulking shaft 401 is connected to the feed pipe 2 through a bearing. Two spiral blades 402 are fixedly connected to the bulking shaft 401, and the two spiral blades 402 have opposite spiral directions and are symmetrically arranged. After the corundum material is poured into the feed pipe 2, the two spiral blades 402 will gradually transport the corundum material to both sides, and the corundum material continues to fall, so that the uniformity of the distribution of the corundum material in the feed pipe 2 can be improved. A bulking slide 403 is provided below the bulking shaft 401, and the bulking slide 403 is slidably connected to the feed pipe 2. Both ends of the bulking slide 403 extend from the feed pipe 2, and a plurality of material holes 404 are opened on the bulking slide 403. A transmission mechanism 5 is provided at the input end of the bulk material shaft 401, and the transmission mechanism 5 is used to transmit the power of the bulk material mechanism to the bulk material shaft 401. A toggle mechanism 6 is provided on one side of the feed pipe 2, and the toggle mechanism 6 is used to move the bulk material slide 403. A rebound mechanism 7 is provided on the other side of the feed pipe 2, and the rebound mechanism 7 is used to reset the bulk material slide 403 after moving. Through the cooperation of the toggle mechanism 6 and the rebound mechanism 7, the bulk material slide 403 is continuously swung left and right. When the corundum material falls onto the bulk material slide 403, as the bulk material slide 403 swings, the corundum material falls through the material hole 404, so that the corundum material is evenly scattered on the magnetic separation cylinder 802. The top surface of the bulk material slide 403 is V-shaped. Such a configuration makes it easier for the corundum material to enter the material hole 404, thereby increasing the feeding speed.

[0028] The toggle mechanism 6 includes a mounting plate 601, which is connected to one side of the feed pipe 2 by screws. A rotating shaft 602 is connected to the mounting plate 601 through a bearing. A cam 603 is fixedly connected to the bottom of the rotating shaft 602, and the cam 603 contacts one side of the bulk material slide 403. A driven bevel gear 604 is fixedly connected to the top of the rotating shaft 602. The driven bevel gear 604 is meshed with a driving bevel gear 605, and the driving bevel gear 605 is fixedly connected to the bulk material shaft 401. The bulk material shaft 401 rotates the rotating shaft 602 through the driven bevel gear 604 and the driving bevel gear 605, and the rotating shaft 602 drives the cam 603 to rotate, and the cam 603 squeezes the side of the bulk material slide 403, thereby moving the bulk material slide 403.

[0029] The rebound mechanism 7 includes a bracket 701, which is connected to the side of the feed pipe 2 away from the toggle mechanism 6 by screws. A fixed sleeve 702 is fixedly connected to the bracket 701, and a movable rod 703 is slidably connected in the fixed sleeve 702. A spring 704 is fixedly connected between the movable rod 703 and the fixed sleeve 702. One end of the fixed sleeve 702 away from the movable rod 703 is fixedly connected to the bulk material slide 403. When the cam 603 squeezes the bulk material slide 403, the bulk material slide 403 moves toward the fixed sleeve 702, so that the movable rod 703 is retracted toward the fixed sleeve 702 and the spring 704 is compressed. When the cam 603 does not squeeze the bulk material slide 403, the spring 704 rebounds, so that the movable rod 703 drives the bulk material slide 403 to reset, and this cycle causes the bulk material slide 403 to rock back and forth left and right.

[0030] The transmission mechanism 5 includes a driving pulley 501 , a belt 502 and a driven pulley 503 . The driving pulley 501 is fixedly connected to the connecting shaft 803 , and the driven pulley 503 is fixedly connected to the bulk material shaft 401 . The driving pulley 501 and the driven pulley 503 are connected via the belt 502 .

[0031] Working principle: When in use, the motor 801 drives the magnetic separation drum 802 to rotate, and the magnetic separation drum 802 drives the connecting shaft 803 to rotate. The connecting shaft 803 drives the bulk material shaft 401 to rotate through the active pulley 501, the belt 502 and the driven pulley 503. The bulk material shaft 401 drives the two spiral blades 402 to rotate, and the corundum is poured into the feed pipe 2 through the feed hopper 3. The corundum material continues to fall. At the same time, the two spiral blades 402 will push the corundum material to both sides, thereby improving the uniformity of the distribution of the corundum material in the feed pipe 2. Subsequently, the corundum material falls onto the bulk material slide 403, and the corundum material falls onto the magnetic separation drum 802 through the material hole 404. During the rotation of the bulk material shaft 401, the bulk material shaft 401 drives the active bevel gear 605 to rotate. The active bevel gear 605 drives the driven bevel gear 604 to rotate, and the driven bevel gear 604 drives the rotating shaft 602 and the cam 603 to rotate. The cam 603 squeezes the side of the bulk material slide 403, so that the bulk material slide 403 moves toward the fixed sleeve 702, so that the movable rod 703 retracts into the fixed sleeve 702, and the spring 704 is compressed. As the cam 603 continues to rotate, the spring 704 begins to rebound, so that the movable rod 703 drives the bulk material slide 403 to reset. This cycle causes the bulk material slide 403 to continuously shake left and right, thereby ensuring that the corundum material falls evenly on the magnetic separation cylinder 802. After the material is magnetically separated by the magnetic separation cylinder 802, the corundum material falls into the material hopper 805, and the metal material separated by the magnetic separation falls into the magnetic hopper 804, and then it can be collected manually.
