Description

Technical Field

[0001] This utility model relates to the technical field of insulator production equipment, specifically to an iron removal device for raw materials of porcelain insulators. Background Technology

[0002] The raw materials for porcelain insulators are diverse, mainly including bauxite, kaolin, and clay. During the manufacturing process, ferromagnetic impurities in these raw materials, such as iron filings and iron oxide particles, can severely affect the insulator's performance and product reliability, thus requiring strict removal. In industrial production, common methods for iron removal from insulator raw materials include dry magnetic separation and wet magnetic separation. Dry magnetic separation is suitable for powdered raw materials, using permanent magnet separators such as magnetic rollers to separate iron impurities. Its disadvantage is that it easily causes dust pollution. Wet magnetic separation involves adsorbing slurry-like raw materials using magnetic rods. Its disadvantage is that it requires manual mixing and slurry preparation, which involves multiple steps and is time-consuming and labor-intensive. A new type of raw material iron removal equipment is needed to solve these problems. Utility Model Content

[0003] To solve the above problems, this utility model proposes an iron removal device for porcelain insulator raw materials, including a slide, several magnetic cylinders rotatably connected inside the slide along the conveying direction, a material holding box at the lower end of the slide, and the bottom of a mixing hopper at the upper end of the slide. A control valve is provided at the bottom of the mixing hopper, a water inlet pipe is connected to the hopper body, a stirring assembly is built into the mixing hopper, a material conveying port is opened on one side of the top of the mixing hopper, a baffle is provided at the material conveying port, the notch of the baffle is connected to the feeding belt, and a crushing assembly is provided inside the baffle.

[0004] Furthermore, the magnetic cylinder surface ring of the magnetic cylinder is provided with several grooves, the central through hole of the magnetic cylinder is rotatably connected to the insertion shaft, the top surface of the limiting plate at the first end of the insertion shaft is provided with a pull ring, and the tail end of the insertion shaft is a threaded rod, which is locked by a nut after passing through the side wall of the slide.

[0005] Furthermore, the control valve includes a valve plate, the top surface of which is in contact with the bottom surface of the mixing hopper. The bottom surface of the mixing hopper is provided with several grooves along the radial direction. The grooves are matched with the holes opened in the valve plate. A vertically downward control rod is provided at the center of the bottom surface of the valve plate. The rod body is rotatably connected to the bottom surface of the slide.

[0008] Furthermore, the bottom surface of the material container is covered with magnetic blocks, and several sets of forklift holes are opened in the side walls on both sides of the material container.

[0009] The beneficial effects of this utility model are as follows: This utility model uses a feeding belt to transport insulator raw materials to the feeding port.

It can also be used with a forklift for overall transfer. This device has a simple structure, high integration, and is convenient and efficient. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings:

[0017] like Figures 1 to 3 As shown, an iron removal device for porcelain insulator raw materials includes a slide rail 1. Several magnetic cylinders 2 are arranged inside the slide rail 1 along the conveying direction. The magnetic cylinder surface of each magnetic cylinder 2 has several grooves 201. A central through-hole of each magnetic cylinder 2 is rotatably connected to a shaft 6. A retaining ring 601 is provided on the top surface of a limiting plate at the front end of the shaft 6. The rear end of the shaft 6 is a threaded rod, which passes through the side wall of the slide rail 1 and is locked by a nut. A material container 3 is located at the lower inclined end of the slide rail 1. Magnetic blocks 301 are laid on the bottom surface of the material container 3. Several sets of forklift holes 302 are opened in the side walls of the material container 3. The forklift holes 302 can accommodate heating elements or insert forklift forks. The upper end of the chute 1 is connected to the bottom of the mixing hopper 4. The bottom of the mixing hopper 4 is equipped with a control valve, which includes a valve plate 7. The top surface of the valve plate 7 is in contact with the bottom surface of the mixing hopper 4. The bottom surface of the mixing hopper 4 has a plurality of grooves 402 arranged radially. The grooves 402 correspond one-to-one with the holes 701 opened in the valve plate 7. When the grooves 402 overlap with the holes 701, the control valve is open; when the holes 701 are blocked by the bottom surface of the mixing hopper 4, the control valve is closed. A vertically downward control rod 702 is provided at the center of the bottom surface of the valve plate 7. The rod 702 is rotatably connected to the bottom surface of the chute 1. After the control rod 702 passes through the chute 1, it is connected to the control panel 8.

[0018] In this embodiment, the mixing hopper 4 is connected to the water inlet pipe 13. The mixing hopper 4 has a built-in stirring assembly, which includes a stirring motor 9. The gearbox of the stirring motor 9 is installed at the center of the top surface of the mixing hopper 4. The output shaft of the gearbox is inserted vertically downward into the mixing hopper 4. The shaft of the output shaft has several support rods 901. A material inlet is opened on one side of the top of the mixing hopper 4. A baffle 401 is provided at the material inlet. The notch of the baffle 401 is connected to the feed belt 5. A crushing assembly is provided inside the baffle 401. The crushing assembly includes crushing rollers 10. The shafts at both ends of the crushing rollers 10 are rotatably connected to the walls of the baffles 401 on both sides. The tail shafts of the two crushing rollers 10 pass through the baffles 401 and are meshed by gears 11. The head shaft of one of the crushing rollers 10 passes through the baffles 401 and is connected to the output end of the crushing motor 12. The convex rings of the two crushing rollers 10 are staggered.

[0019] The working principle of this utility model is as follows:

[0020] The feed belt 5 is opened to transport the insulator raw materials into the enclosure 401. The crushing motor 12 is started, driving the two crushing rollers 10 to rotate in opposite directions. The raw material particles crushed by the crushing rollers 10 fall into the mixing hopper 4. During the crushing process, the water inlet pipe 13 is opened to inject liquid into the mixing hopper 4 simultaneously. The stirring motor 9 is started to drive each support rod 901 to mix and slurry. After the raw material particles and water are fully mixed and stirred into a slurry, the control panel 8 is rotated to open the control valve, and the slurry flows into the slide 1. Under the action of gravity, the slurry flows into the holding box 3. During the downward movement, the slurry pushes the groove 201 to drive the magnetic cylinder 2 to rotate. Each magnetic cylinder 2 adsorbs the ferromagnetic particles in the slurry step by step. The slurry falling into the holding box 3 is allowed to settle in the box. The remaining ferromagnetic particles are adsorbed to the bottom of the box by the magnetic block 301. An electric heating tube can be placed in the forklift hole 302 to heat and concentrate the slurry. Once the container 3 is full, it can be moved as a whole using a forklift. When the magnetic cylinder 2 needs to be cleaned, the nut can be unscrewed and the insert shaft 6 can be pulled out. This device has a simple structure, high integration, and is convenient and efficient, saving a significant amount of labor costs.
