Description

Technical Field

[0001] This utility model relates to the field of magnetic separation technology, specifically to a primary magnetic separation device for heavy zinc oxide. Background Technology

[0002] Zinc oxide (chemical formula ZnO) is an oxide of zinc, commonly known as zinc white. It is a commonly used chemical additive in the metallurgical and chemical industries. However, heavy zinc oxide itself is generally not magnetic or has very weak magnetic properties. Impurities mixed in during the production process, such as iron and its oxides, usually have strong magnetic properties. These impurities will affect the purity and quality of zinc oxide, and thus affect its application performance in downstream products.

[0003] A search revealed that Chinese patent CN221907636U discloses a primary magnetic separation device for heavy zinc oxide. Its workflow is roughly as follows: during the conveying of heavy zinc oxide, the pricking action of the bristles breaks the zinc oxide clumps into a loose state. When the loose heavy zinc oxide reaches the magnetic separation mechanism, the iron particles can be better removed. In the subsequent magnetic separation process, a magnetic roller is set at the discharge end of the conveying mechanism. When the heavy zinc oxide reaches the magnetic roller along the conveyor belt, the iron particles can be adsorbed onto the surface of the conveyor belt. However, the mixture of the broken heavy zinc oxide and the iron particles, accumulating on the conveyor belt, may make it difficult to effectively remove and transfer the iron particles from the loose heavy zinc oxide. Utility Model Content

[0004] This invention proposes a primary magnetic separation device for heavy zinc oxide, which solves the problem that iron particles in loose heavy zinc oxide are difficult to effectively remove and transfer in the prior art.

[0005] The technical solution of this utility model is as follows: A primary magnetic separation device for heavy zinc oxide includes a shell, with a feed inlet at the top of the shell, and also includes a guide plate, a conveying mechanism, and a vibration mechanism. The guide plate is inclinedly disposed below the feed inlet to guide the flow of material. The conveying mechanism is disposed inside the shell and below the guide plate to convey material. The vibration mechanism is disposed on both sides of the conveying mechanism to vibrate the material being conveyed.

[0006] To transport heavy zinc oxide and separate the mixed iron particles therein, the conveying mechanism includes a first motor, a drive shaft, a drive roller, a first rotating shaft, a magnetic roller, a conveyor belt, and rubber retaining rings. The first motor is mounted on the outer wall of the housing; the output end of the first motor passes through the outer wall of the housing. One end of the drive shaft is rotatably connected to the inner wall of the housing, and the other end is coaxially connected to the output end of the first motor. The drive roller is sleeved on the drive shaft and coaxially fixedly connected to the drive shaft. The first rotating shaft is located on one side of the drive shaft, and its two ends are rotatably connected to the two inner walls of the housing, respectively. The magnetic roller is sleeved on the first rotating shaft and coaxially fixedly connected to the first rotating shaft. The conveyor belt is tensioned and sleeved on the drive roller and the magnetic roller, and the rubber retaining rings are provided at both ends of the conveyor belt.

[0007] To prevent the accumulation of heavy zinc oxide and iron particles on the conveyor belt and to prevent the heavy zinc oxide and iron particles from mixing and accumulating, thus affecting the magnetic roller's adsorption of iron particles, the vibration mechanism includes two fixed seats, a spring, a mounting seat, a second rotating shaft, a support roller, and two vibration motors. The bottom ends of the two fixed seats are fixedly connected to the inner bottom wall of the housing and are symmetrically arranged on both sides of the conveyor belt. The bottom end of the spring is fixedly connected to the fixed seat, and the bottom end of the mounting seat is fixedly connected to the top end of the spring. The two ends of the second rotating shaft are rotatably connected to the two mounting seats respectively. The support roller is sleeved on the second rotating shaft and is coaxially fixedly connected to the second rotating shaft. The vibration motors are mounted on the mounting seats.

[0008] In order to separate the iron particles mixed in the heavy zinc oxide and facilitate the adsorption of iron particles by the magnetic roller, the support roller is located between the drive roller and the magnetic roller and is close to the magnetic roller.

[0009] To facilitate the separate collection of heavy zinc oxide and iron particles, the bottom of the shell is provided with a first discharge port and a second discharge port. The first discharge port is located at one end of the bottom of the shell, and the second discharge port is located below the left side of the magnetic roller.

[0010] To accommodate the longitudinal vibration of the conveyor belt by the vibration mechanism and to maintain the corresponding tension during vibration, the conveyor belt is made of rubber.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. In this utility model, through the cooperation of the guide plate and the conveying mechanism, the material slides onto the conveyor belt by the guide plate, and is driven by the first motor to drive the transmission belt, thus driving the material to be conveyed horizontally. By setting a rubber retaining ring, the material is prevented from being leaked from the conveyor belt.

[0013] 2. In this utility model, by setting up a vibration mechanism, during the material conveying process, the vibration motor drives the conveyor belt near the magnetic roller to vibrate, causing the material on the conveyor belt to vibrate. This places the iron particles on the surface of the conveyor belt, while most of the heavy zinc oxide is above the iron particles. Through the adsorption of the iron particles by the magnetic roller, the iron particles are adsorbed onto the surface of the conveyor belt near the magnetic roller and transported. Then, the heavy zinc oxide is transferred out of the shell through the first discharge port, while the iron particles will be adsorbed onto the surface of the conveyor belt and continue to be conveyed. When the distance from the magnetic roller is far, the magnetic force on the iron particles decreases, and they fall to the second discharge port and are transferred out of the shell under their own gravity. This can effectively separate and collect the iron particles mixed in the heavy zinc oxide, avoiding excessive accumulation of heavy zinc oxide and iron particles on the conveyor belt and affecting the subsequent adsorption of the particles by the magnetic roller.

[0021] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0022] like Figures 1-4 As shown, this embodiment proposes a primary magnetic separation device for heavy zinc oxide, including a shell 1, a feed inlet 2 at the top of the shell 1, and also including a guide plate 3, a conveying mechanism and a vibration mechanism.

[0023] The guide plate 3 is inclined and set below the feed inlet 2 to guide the flow of materials. Two guide plates 19 are symmetrically arranged on the guide plate 3. The distance between the two guide plates 19 is less than the distance between the two rubber baffles 10. The material entering from the feed inlet 2 falls onto the guide plate 3 and is between the two guide plates 19. The material slides under the action of its own gravity.

[0024] The conveying mechanism is located inside the housing 1 and below the guide plate 3. It is used to convey materials. To convey heavy zinc oxide and separate the mixed iron particles, the conveying mechanism includes a first motor 4, a drive shaft 5, a drive roller 6, a first rotating shaft 7, a magnetic roller 8, a conveyor belt 9, and a rubber retaining ring 10. The first motor 4 is mounted on the outer wall of the housing 1; its output end penetrates the outer wall of the housing 1. One end of the drive shaft 5 is rotatably connected to the inner wall of the housing 1, and the other end is coaxially connected to the output end of the first motor 4. The drive roller 6 is sleeved on the drive shaft 5 and coaxially fixedly connected to it. The center point of the drive roller 6's axis is the same as the center point of the drive shaft 5's axis. The first rotating shaft 7 is located on one side of the drive shaft 5, and its two ends are rotatably connected to the two inner walls of the housing 1, respectively. The magnetic roller 8 is sleeved on the first rotating shaft 7 and coaxially fixedly connected to it. The conveyor belt 9 is tensioned and fitted onto the drive roller 6 and the magnetic roller 8. The width of the conveyor belt 9 is less than the length of the drive shaft 5 and the first rotating shaft 7, and is the same as the length of the drive roller 6 and the magnetic roller 8. Rubber retaining rings 10 are provided at both ends of the conveyor belt 9. When the first motor 4 is started, the output end of the first motor 4 rotates and drives the drive shaft 5 to rotate. The drive shaft 5 drives the drive roller 6 to rotate. The rotation of the drive roller 6 drives the transmission belt tensioned and fitted onto the drive roller 6 to rotate. The transmission belt drives the magnetic roller 8 and the first rotating shaft 7 to rotate. The conveyor belt 9 drives the rubber retaining rings 10 to rotate. When the material is transferred to one end of the top of the conveyor belt 9 through the guide plate 3 and is above the drive roller 6, it is then conveyed horizontally and slowly approaches the magnetic roller 8. The magnetic force generated by the magnetic roller 8 is small and will not cause the iron particles to be directly adsorbed onto the surface of the conveyor belt 9 and remain stationary. The iron particles will still be conveyed through the conveyor belt 9.

[0025] Vibration mechanisms are installed on both sides of the conveying mechanism to vibrate the conveyed material. To prevent heavy zinc oxide and iron particles from accumulating on the conveyor belt 9 and to prevent the heavy zinc oxide and iron particles from mixing and accumulating, thus affecting the magnetic roller 8's adsorption of iron particles, the vibration mechanism includes two fixed seats 11, springs 12, mounting seats 13, a second rotating shaft 14, a support roller 15, and two vibration motors 16. The bottom ends of the two fixed seats 11 are fixedly connected to the inner bottom wall of the housing 1 and are symmetrically arranged on both sides of the conveyor belt 9. The springs 12... The bottom end is fixedly connected to the fixed seat 11. All springs 12 have high rigidity. The bottom end of the mounting seat 13 is fixedly connected to the top end of the spring 12. The mounting seat 13 is L-shaped. Both ends of the second rotating shaft 14 are rotatably connected to the two mounting seats 13 respectively. The support roller 15 is sleeved on the second rotating shaft 14 and coaxially fixedly connected to it. The support roller 15 is positioned between the tensioned conveyor belts 9, with its top end in contact with the conveyor belt 9. This is to separate the iron particles mixed in the heavy zinc oxide and facilitate the magnetic roller 8's contact with the iron particles. The adsorption mechanism consists of a support roller 15 positioned between and close to the drive roller 6 and the magnetic roller 8. A second motor is mounted on a mounting base 13, and a vibration motor 16 is also mounted on the mounting base 13. To accommodate the longitudinal vibration of the conveyor belt 9 by the vibration mechanism and to maintain the corresponding tension during vibration, the conveyor belt 9 is made of rubber. By starting the vibration motor 16, the vibration motor 16 drives the two mounting bases 13 to vibrate longitudinally. The mounting base 13 drives the spring 12 to compress or extend, and the mounting base 13 drives the second rotating shaft 14 and the support roller 15 to move longitudinally up and down repeatedly. The support roller 15 vibrates the conveyor belt 9, causing the surface of the conveyor belt 9 near the magnetic roller 8 to vibrate continuously longitudinally, thus causing the material on the conveyor belt 9 to vibrate. Since the density of iron particles is greater than that of heavy zinc oxide, during vibration, the iron particles will be on the moving surface of the conveyor belt 9, while most of the heavy zinc oxide will be above the iron particles. Through the adsorption of the iron particles by the magnetic roller 8, the iron particles are adsorbed onto the surface of the conveyor belt 9 near the magnetic roller 8 and transported.

[0026] To facilitate the separation and collection of heavy zinc oxide and iron particles, a first discharge port 17 and a second discharge port 18 are provided at the bottom of the housing 1. The first discharge port 17 is located at one end of the bottom of the housing 1, and the second discharge port 18 is located below the left side of the magnetic roller 8. During the subsequent conveying process, heavy zinc oxide is transferred out of the housing 1 through the first discharge port 17, while iron particles are adsorbed on the surface of the conveyor belt 9 and continue to be conveyed. When the distance from the magnetic roller 8 is relatively far, the magnetic force on the iron particles decreases, and they fall to the second discharge port 18 and are transferred out of the housing 1 by their own gravity.

[0027] Working Principle: The primary magnetic separator for heavy zinc oxide is placed in a suitable location. Material enters the housing 1 through the feed inlet 2. The material falling from the feed inlet 2 onto the guide plate 3 and between the two guide plates 19 is slid onto the conveyor belt 9 under its own weight. The first motor 4 is started, and its output rotates, driving the drive shaft 5. The drive shaft 5 drives the drive roller 6, which in turn drives the transmission belt tensioned on it. The transmission belt drives the magnetic roller 8 and the first rotating shaft 7 to rotate, and the conveyor belt 9 drives the rubber retaining ring 10 to rotate. This drives the material to be conveyed horizontally. During the conveying process, the vibration motor 16 is started, causing the two mounting seats 13 to vibrate longitudinally. The mounting seats 13 cause the springs 12 to compress or extend, and the mounting seats 13 also drive the second rotating shaft 14 and the support... The support roller 15 moves up and down repeatedly in the longitudinal direction, vibrating the conveyor belt 9. This causes the surface of the conveyor belt 9 near the magnetic roller 8 to vibrate continuously in the longitudinal direction, causing the material on the conveyor belt 9 to vibrate. Since the density of iron particles is greater than that of heavy zinc oxide, during the vibration process, the iron particles will be on the moving surface of the conveyor belt 9, while most of the heavy zinc oxide will be above the iron particles. Through the adsorption of the iron particles by the magnetic roller 8, the iron particles are adsorbed onto the surface of the conveyor belt 9 near the magnetic roller 8 and transported. Then, the heavy zinc oxide is transferred out of the shell 1 through the first discharge port 17, while the iron particles will be adsorbed onto the surface of the conveyor belt 9 and continue to be transported. When the distance from the magnetic roller 8 is far, the magnetic force on the iron particles decreases, and they fall to the second discharge port 18 under their own gravity and are transferred out of the shell 1. This completes the separation of iron particles in the heavy zinc oxide.

[0028] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
