Description

Technical Field

[0001] This utility model relates to the technical field of wet countercurrent permanent magnet drum separators, specifically to a scraper mechanism for a wet countercurrent permanent magnet drum separator. Background Technology

[0002] Magnetic separators are specialized equipment that remove iron powder from mineral particles by using magnetic and mechanical forces. In the existing technology, magnetic separators are divided into two types according to the moisture content of the mineral powder: dry magnetic separators and wet magnetic separators. Among them, dry disc magnetic separators are mainly used for separating weakly magnetic minerals smaller than 2-3 mm and for the further refining of rare metal ores.

[0003] According to a public disclosure of a wet magnetic separator (publication number: CN101940978A), it includes a first sluice for directional flow of slurry, a second sluice and a storage tank arranged sequentially on one side of the first sluice, and a magnetic separation device suspended above the first sluice, the second sluice, and the storage tank. The magnetic separation device has a disc driven by a power device that can rotate along its plane and a magnet mounted on the disc. However, in the above-mentioned device, the components such as the first sluice and the second sluice cooperate with each other, making it difficult to scrape the minerals after magnetic separation from the inner wall of the magnetic drum, making it difficult to avoid excessive mineral deposition, making it difficult to maintain the separation efficiency of the equipment while quantitatively feeding the material, making it difficult to avoid excessive mineral deposition on the surface of the magnetic drum, and making it difficult to prevent mineral agglomeration and blockage inside the equipment. It needs to be improved. Utility Model Content

[0004] This invention proposes a scraper mechanism for a wet countercurrent permanent magnet drum separator, which solves the problem of mineral accumulation and clogging of the equipment interior in related technologies.

[0005] The technical solution of this utility model is as follows: A scraper mechanism for a wet countercurrent permanent magnet drum separator includes a protective shell, a support frame is fixedly connected to the side of the protective shell, and a reaction tank is arranged inside the protective shell.

[0006] The protective shell is equipped with a processing device, which includes a motor. The motor is fixedly connected to the side of the support frame. The output shaft of the motor is fixedly connected to a rotating rod. A protective sleeve is fixedly connected to the circumferential surface of the rotating rod. A fixing frame is fixedly connected to the circumferential surface of the protective sleeve. A scraper is fixedly connected to the side of the fixing frame. The processing device includes a feeding structure.

[0007] Optionally, the feeding structure includes a rotating rod, which is fixedly connected to one end of a rotating rod. A belt is rotatably connected to the circumferential surface of the rotating rod. The rotating rod is connected to a rotating shaft via the belt drive. A fixed rod is fixedly connected to one end of the rotating shaft. A feeding plate is fixedly connected to the circumferential surface of the fixed rod.

[0008] Optionally, the number of feeding plates is set to several, and they are arranged in a circumferential array on the circumferential surface of the fixed rod. The rotation of the feeding plates makes the feeding process more precise and controllable. Quantitative feeding helps to control the flow and distribution of materials, and ensures that the process conditions of subsequent processing are more stable.

[0009] Optionally, the processing device includes a cooling structure, which includes a connecting belt rotatably connected to the circumferential surface of a rotating rod. The rotating rod is driven by a rotating shaft via the connecting belt. A half gear is fixedly connected to the circumferential surface of the rotating shaft. A rotating rod A is rotatably connected to the side of the protective shell. A gear is fixedly connected to the circumferential surface of the rotating rod A. A water pipe is fixedly connected to one end of the rotating rod A, and a nozzle passes through the circumferential surface of the water pipe.

[0010] Optionally, a fixing sleeve is fixedly connected to the circumferential surface of the water pipe, and a support rod is rotatably connected to the circumferential surface of the fixing sleeve. The end of the support rod away from the fixing sleeve is fixedly connected to the inner wall of the protective shell. The water pipe can cover a larger area of ​​the reaction tank and distribute cooling water over a wider area through the nozzle, thereby increasing the cooling area and improving the cooling efficiency.

[0011] Optionally, a torsion spring is fixedly connected to the circumferential surface of the rotating rod A, and the end of the torsion spring away from the rotating rod A is fixedly connected to the side of the protective shell. The reciprocating motion of the water pipe is restored by the elasticity of the torsion spring, which effectively utilizes mechanical energy, eliminates the need for external energy to drive it, and reduces energy consumption.

[0012] Optionally, the torsion spring is initially in a relaxed state, and the toothed side of the half gear meshes with the side of the gear. The design of the torsion spring allows the rotating rod A to automatically reset, reducing manual intervention.

[0013] Optionally, the number of nozzles is set to several, and they are arranged in a linear array on the circumference of the water pipe. The nozzle design can extend the service life of the magnetic separator and its components by improving the cooling effect and avoiding local overheating of the equipment.

[0014] Optionally, the number of the fixing frames is set to several, and they are arranged in a linear array on the circumference of the rotating rod. The design of the fixing frames is conducive to fixing the scraper. The scraper can effectively prevent minerals from accumulating and clogging the inside of the equipment, thereby reducing the frequency of equipment maintenance and repair costs.

[0015] Optionally, the side of the scraper contacts the inner wall of the reaction tank, and the number of the support rods is set to several and arranged in a linear array on the inner wall of the protective shell. The scraper removes the minerals after magnetic separation from the inner wall of the magnetic cylinder by rotating, thus avoiding excessive deposition of minerals on the surface of the magnetic cylinder.

[0016] The working principle and beneficial effects of this utility model are as follows:

[0017] 1. In this utility model, the force of the rotating rod driven by the motor cooperates with the components such as the fixed frame, rotating shaft and scraper in the processing device. This achieves the effect of rotating the fixed sleeve through the rotation of the rotating rod, rotating the fixed frame through the rotation of the fixed sleeve, and rotating the scraper through the rotation of the fixed frame. This achieves the effect of scraping the minerals after magnetic separation from the inner wall of the magnetic drum, avoiding excessive mineral deposition, maintaining the sorting efficiency of the equipment while quantitatively feeding the material, and preventing excessive mineral deposition on the surface of the magnetic drum, effectively preventing mineral accumulation and blockage inside the equipment.

[0018] 2. In this utility model, the force that drives the connecting belt to rotate through the rotation of the rotating rod cooperates with the torsion spring, half gear, and gear components in the processing device. This enables the water pipe to rotate through the rotation of the rotating rod A, and then the nozzle to rotate through the rotation of the water pipe. When the toothed side of the half gear disengages from the gear, the rotating rod A drives the water pipe to reset through the elastic force of the torsion spring. This achieves the effect of cooling the reaction tank through the reciprocating motion of the water pipe, increasing the cooling area, improving the cooling efficiency, and enhancing the overall effect of the cooling system. This also helps to reduce excessive heat generated during equipment operation. Attached Figure Description

[0030] Example 1

[0031] Reference Figures 1-5 The first embodiment of this utility model proposes a scraper mechanism for a wet countercurrent permanent magnet drum separator, including a protective shell 101, a support frame 102 fixedly connected to the side of the protective shell 101, and a reaction tank 103 arranged inside the protective shell 101.

[0032] The protective shell 101 is equipped with a processing device 2. The processing device 2 includes a motor 201, which is fixedly connected to the side of the support frame 102. The output shaft of the motor 201 is fixedly connected to a rotating rod 202. A protective sleeve 203 is fixedly connected to the circumferential surface of the rotating rod 202. A fixing frame 204 is fixedly connected to the circumferential surface of the protective sleeve 203. A scraper 205 is fixedly connected to the side of the fixing frame 204. The processing device 2 includes a feeding structure.

[0033] The feeding structure includes a rotating rod 206, which is fixedly connected to one end of a rotating rod 202. A belt 207 is rotatably connected to the circumferential surface of the rotating rod 206. The rotating rod 206 is driven by a rotating shaft 208 through the belt 207. A fixing rod 209 is fixedly connected to one end of the rotating shaft 208. A feeding plate 210 is fixedly connected to the circumferential surface of the fixing rod 209.

[0034] The number of feeding plates 210 is set to several, and they are arranged in a circumferential array on the circumferential surface of the fixed rod 209. The rotation of the feeding plates 210 makes the feeding process more precise and controllable. Quantitative feeding helps to control the flow and distribution of materials, and ensures that the process conditions of subsequent processing are more stable.

[0035] In this embodiment, the application uses a motor 201 to drive a rotating rod 202 to rotate, which in turn drives a protective sleeve 203 to rotate. The protective sleeve 203 then drives a fixed frame 204 to rotate, which in turn drives a scraper 205 to rotate. This achieves the function of scraping away the minerals after magnetic separation from the inner wall of the magnetic drum, avoiding excessive mineral deposition and maintaining the sorting efficiency of the equipment. The rotating rod 202 drives a rotating rod 206 to rotate, which in turn drives a belt 207 to rotate. The belt 207 then drives a rotating shaft 208 to rotate, which in turn drives a fixed rod 209 to rotate. The fixed rod 209 then drives a feeding plate 210 to rotate, achieving the function of quantitative feeding.

[0036] Example 2

[0037] Reference Figures 1-5 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the processing device 2 includes a cooling structure, which includes a connecting belt 211. The connecting belt 211 is rotatably connected to the circumferential surface of the rotating rod 206. The rotating rod 206 is connected to a rotating shaft 212 via the connecting belt 211. A half gear 213 is fixedly connected to the circumferential surface of the rotating shaft 212. A rotating rod A214 is rotatably connected to the side of the protective shell 101. A gear 215 is fixedly connected to the circumferential surface of the rotating rod A214. A water pipe 217 is fixedly connected to one end of the rotating rod A214. A nozzle 218 passes through the circumferential surface of the water pipe 217.

[0038] A fixing sleeve 220 is fixedly connected to the circumferential surface of the water pipe 217. A support rod 219 is rotatably connected to the circumferential surface of the fixing sleeve 220. The end of the support rod 219 away from the fixing sleeve 220 is fixedly connected to the inner wall of the protective shell 101. The water pipe 217 can cover a larger area of ​​the reaction tank 103. The cooling water is distributed to a wider area through the nozzle 218, thereby increasing the cooling area and improving the cooling efficiency.

[0039] A torsion spring 216 is fixedly connected to the circumferential surface of the rotating rod A214. The end of the torsion spring 216 away from the rotating rod A214 is fixedly connected to the side of the protective shell 101. The reciprocating motion of the water pipe 217 is effectively utilized by the elastic reset of the torsion spring 216, without the need for external energy to drive it, thus reducing energy consumption.

[0040] The torsion spring 216 is initially in a relaxed state. The toothed side of the half gear 213 meshes with the side of the gear 215. The design of the torsion spring 216 allows the rotating rod A214 to automatically reset, reducing manual intervention.

[0041] The number of nozzles 218 is set to several and arranged in a linear array on the circumference of the water pipe 217. The design of the nozzles 218 can extend the service life of the magnetic separator and its components by improving the cooling effect and avoiding local overheating of the equipment.

[0042] The number of fixed frames 204 is set to several, and they are arranged in a linear array on the circumference of the rotating rod 202. The design of the fixed frames 204 is conducive to fixing the scraper 205. The scraper 205 can effectively prevent minerals from accumulating and clogging the inside of the equipment, reducing the frequency of equipment maintenance and repair costs.

[0043] The side of the scraper 205 contacts the inner wall of the reaction tank 103. The number of support rods 219 is set to several and arranged linearly on the inner wall of the protective shell 101. The scraper 205 scrapes the minerals after magnetic separation from the inner wall of the magnetic cylinder by rotating, thus avoiding excessive deposition of minerals on the surface of the magnetic cylinder.

[0044] Compared to Embodiment 1, further, the rotating rod 206 rotates to drive the connecting belt 211 to rotate, and the rotating belt 211 rotates to drive the rotating shaft 212 to rotate. The rotating shaft 212 rotates to drive the half gear 213 to rotate. When the toothed side of the half gear 213 meshes with the gear 215, the half gear 213 drives the gear 215 to rotate. The rotation of the gear 215 then drives the rotating rod A214 to rotate, which in turn drives the water pipe 217 to rotate. The rotation of the water pipe 217 then drives the nozzle 218 to rotate. When the toothed side of the half gear 213 disengages from the gear 215, the rotating rod A214 drives the water pipe 217 to reset through the elastic force of the torsion spring 216. This achieves the effect of cooling the reaction tank 103 by the reciprocating motion of the water pipe 217, increasing the cooling area.
