Description

Technical Field

[0001] This utility model relates to the field of iron removal technology for white fused alumina powder, and specifically to iron removal equipment for white fused alumina powder. Background Technology

[0002] In the production of corundum powder, iron powder impurities can severely affect product purity and performance, making iron removal equipment a crucial component. Existing iron removal equipment for white corundum powder suffers from two major problems:

[0003] First, the iron removal efficiency is low. Most of the magnetic components of the equipment are arranged in a single row or simply in parallel, resulting in blind spots in the magnetic field coverage. Tiny iron powders are easily missed, and the material has a short contact time with the magnetic field, so the adsorption is incomplete.

[0004] Secondly, the operation is cumbersome. The cleaning of the magnetic suction component and the driving of the material guiding structure are mostly controlled independently. Operators need to complete actions such as positioning the material guiding hopper and moving the magnetic suction component to scrape iron separately. The steps are redundant and the timing of the actions is prone to being disordered, resulting in iron powder scattering and contaminating the material, which increases the subsequent cleaning cost.

[0005] In addition, the material guiding structure of some equipment lacks reliable limiting, making it easy to detach from the cylinder during operation. The magnetic attraction component reset relies on manual pushing, and the ease of operation needs to be optimized. Utility Model Content

[0006] The purpose of this invention is to provide a white fused alumina powder iron removal device to solve the above problems, as detailed below.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] The white corundum powder iron removal equipment provided by this utility model includes a cylinder, a magnetic suction component is horizontally slidably connected inside the cylinder, and a guide hopper is inclinedly slidably connected on the cylinder. The guide hopper slides outside the cylinder under the action of gravity, and the guide hopper is located below the magnetic suction component.

[0009] A pulling mechanism is fixedly connected to the cylinder body, which is used to move the magnetic suction component out of the cylinder body and pull the guide hopper into the cylinder body. The pulling mechanism can drive the guide hopper first and then drive the magnetic suction component.

[0010] Preferably, the magnetic attraction assembly includes a connecting plate and several magnetic rods that are horizontally slidably connected to the cylinder. The magnetic rods are arranged in several layers, with magnetic rods of different heights staggered. The end of each magnetic rod that passes through the cylinder is fixedly connected to the connecting plate.

[0011] Preferably, a baffle is fixedly connected to one side of the guide hopper inserted into the cylinder to prevent the guide hopper from detaching from the cylinder.

[0012] Preferably, the pulling mechanism includes two connecting rods slidably connected to both sides of the cylinder and two pull rods. The pull rods are provided with misaligned surfaces, which are spaced from and correspond to the connecting plate. Two guide wheels are fixedly connected to the cylinder. A pull rope is fixedly connected between the near ends of the connecting rods and the pull rods, and the pull rope passes through the guide wheels.

[0013] Preferably, the connecting rod is arranged along the length of the guide hopper, and a guide sleeve is slidably connected to the surface of the connecting rod, and the guide sleeve is fixedly connected to the cylinder.

[0014] Preferably, a handle is fixedly connected between the two pull rods.

[0015] Preferably, the pull rod is horizontally arranged along the length of the magnet rod, and a guide sleeve is slidably connected to the surface of the pull rod, and the guide sleeve is fixedly connected to the cylinder.

[0016] Preferably, the pulling mechanism further includes a reset component for pulling the magnetic component into the cylinder.

[0018] The beneficial effects are:

[0019] 1. The magnetic rods of the magnetic attraction component are arranged in multiple layers in a staggered manner to form a magnetic field without blind spots, which prolongs the contact time between white fused alumina powder and the magnetic field, significantly improves the capture rate of fine iron powder, solves the problem of leakage in traditional equipment, and effectively ensures the purity of white fused alumina powder.

[0020] 2. The pulling mechanism, through the initial spacing design of the misaligned surface and the connecting plate, achieves the linkage effect of driving the guide hopper and the magnetic suction component in sequence with one pull, eliminating the need to operate the two parts separately, simplifying the operation process, reducing labor intensity, and avoiding iron powder scattering caused by disordered action sequence.

[0021] 3. The baffle design of the guide hopper provides reliable limiting and prevents it from detaching from the cylinder during operation. The spring of the reset component works in conjunction with the guide rod to ensure that the magnetic suction component automatically and accurately resets without manual adjustment, thus ensuring continuous and stable operation of the equipment.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] See Figures 1-4 As shown, this utility model provides a white corundum powder iron removal device, including a cylinder 1, a magnetic suction component 3 is horizontally slidably connected inside the cylinder 1, and a guide hopper 2 is inclinedly slidably connected on the cylinder 1. The guide hopper 2 slides outside the cylinder 1 under the action of gravity, and the guide hopper 2 is located below the magnetic suction component 3.

[0031] A pulling mechanism 4 is fixedly connected to the cylinder 1, which is used to move the magnetic suction component 3 out of the cylinder 1 and pull the guide hopper 2 into the cylinder 1. The pulling mechanism 4 can drive the guide hopper 2 first and then drive the magnetic suction component 3.

[0032] This equipment achieves iron removal from white fused alumina powder through a combination of flow guidance in the cylinder 1 and magnetic adsorption. At this stage, all components are in their initial working state, forming a stable iron removal channel. First, the cylinder 1 is connected to the discharge end of the white fused alumina powder production equipment, making the cylinder 1 a conveying channel for the white fused alumina powder, ensuring that the material can flow completely through the interior of the cylinder 1. At this time, the magnetic adsorption component 3 maintains its initial position under the action of the reset component 5, and the magnets 302 of different heights are staggered to maximize the contact area with the white fused alumina powder and improve the iron powder adsorption efficiency.

[0033] Under the influence of gravity, the guide hopper 2 slides naturally to the outside of the cylinder 1. Its insertion side into the cylinder 1 is limited by a baffle 201 to prevent complete detachment. Simultaneously, the end face of the guide hopper 2 is flush with the inner wall of the cylinder 1, precisely sealing the opening on the cylinder 1 for the guide hopper 2 to pass through, preventing leakage of white fused alumina powder during transport. When the white fused alumina powder flows in from the top of the cylinder 1 and is conveyed downwards, the iron powder in the material is firmly adsorbed onto the surface of the magnetic rod 302 under the influence of the magnetic field. The iron-removed white fused alumina powder then smoothly passes through the cylinder 1, achieving initial separation of iron powder and white fused alumina powder.

[0034] See Figure 1 and Figure 2 The magnetic suction assembly 3 includes a connecting plate 301 and several magnetic rods 302 that are horizontally slidably connected inside the cylinder 1. The magnetic rods 302 are arranged in several layers, with different heights of the magnetic rods 302 staggered. The end of each magnetic rod 302 that passes through the cylinder 1 is fixedly connected to the connecting plate 301. A baffle 201 is fixedly connected to one side of the guide hopper 2 that is inserted into the cylinder 1 to prevent the guide hopper 2 from detaching from the cylinder 1.

[0035] In this embodiment, the magnetic rods 302 are arranged in multiple staggered layers to form a magnetic field without blind spots, which prolongs the contact time between the material and the magnetic field and improves the capture rate of tiny iron powders. The magnetic rods 302 generate a magnetic field to adsorb the flowing iron powder, and the non-magnetic white corundum powder is smoothly discharged, thus achieving separation.

[0036] See Figure 1 and Figure 2The pulling mechanism 4 includes two connecting rods 402 and two pull rods 404 slidably connected to both sides of the cylinder 1. The pull rods 404 have a misaligned surface 407, which is spaced from and corresponds to the connecting plate 301. Two guide wheels 406 are fixedly connected to the cylinder 1. A pull rope 403 is fixedly connected between the near ends of the connecting rods 402 and the pull rods 404, passing through the guide wheels 406. The connecting rods 402 are arranged along the length of the guide hopper 2. A guide sleeve 401 is slidably connected to the surface of the connecting rods 402 and is fixedly connected to the cylinder 1. A handle 408 is fixedly connected between the two pull rods 404. The pull rods 404 are horizontally arranged along the length of the magnetic rod 302. A guide sleeve 405 is slidably connected to the surface of the pull rods 404 and is fixedly connected to the cylinder 1. The pulling mechanism 4 also includes a reset assembly 5, used to pull the magnetic suction assembly 3 into the cylinder 1. The reset assembly 5 includes a guide rod 501 that is horizontally slidably connected inside the cylinder 1. The guide rod 501 is fixedly connected to the connecting plate 301. A retaining ring 503 is fixedly connected to one end of the guide rod 501 away from the connecting plate 301. A spring 502 is sleeved on the guide rod 501. The two ends of the spring 502 are fixedly connected to the retaining ring 503 and the cylinder 1, respectively.

[0037] In this implementation, after the white fused alumina powder is conveyed, the equipment enters the iron powder cleaning process. This stage relies on the staggered driving characteristics of the pulling mechanism 4, which first drives the guide hopper 2 and then the magnetic suction component 3, to achieve the scraping and collection of iron powder. The operator holds the handle 408 between the two pull rods 404 and pulls the pull rods 404 outwards along the length of the magnetic rod 302. The pull rods 404 maintain a horizontal and stable sliding position under the constraint of the guide sleeve 405.

[0038] In the initial pulling phase, the pull rod 404, through the coordination of the pull rope 403 and the guide wheel 406, drives the connecting rods 402 on both sides to slide along the guide sleeve 401. The connecting rods 402 directly act on the guide hopper 2, overcoming the gravity of the guide hopper 2 and pulling it into the cylinder 1, causing the guide hopper 2 to move from the initial standby position to directly below the magnetic rod 302, forming an iron powder receiving channel. At this time, the misaligned surface 407 on the pull rod 404 and the connecting plate 301 of the magnetic attraction component 3 still maintain a distance. Under the pre-tightening force of the spring 502 of the reset component 5, the magnetic attraction component 3 maintains its adsorption position inside the cylinder 1, ensuring that the guide hopper 2 completes its receiving preparation first.

[0039] As the pull rod 404 continues to pull, when the misaligned surface 407 contacts the connecting plate 301, the pulling force is transmitted to the connecting plate 301 through the misaligned surface 407, causing the magnetic rod 302 to move outward from the cylinder 1. During this process, the iron powder adsorbed on the surface of the magnetic rod 302 is rigidly blocked by the inner wall of the cylinder 1, forming a relative scraping force that completely peels the iron powder off the surface of the magnetic rod 302. The peeled iron powder falls into the pre-positioned guide hopper 2 under the action of gravity, and slides out of the cylinder 1 along the inclined angle of the guide hopper 2, completing the centralized collection and discharge of the iron powder.

[0040] In summary, the pulling mechanism 4 can improve the ease of operation of the equipment, eliminating the need to drive the magnetic suction component 3 and the guide hopper 2 separately. This effect is achieved by the pulling mechanism 4 driving the guide hopper 2 and the magnetic suction component 3 sequentially. The core of achieving sequential driving lies in the initial distance between the misaligned surface 407 and the connecting plate 301.

[0041] Working principle:

[0042] The cylinder 1 is installed on the white alumina powder production equipment. The cylinder 1 can serve as a channel for white alumina powder. When white alumina powder passes through, the iron powder inside is attracted to the magnet rod 302 of the magnetic attraction component 3. After the white alumina powder is conveyed, the guide hopper 2 and the magnetic attraction component 3 are pulled by the pulling mechanism 4. The guide hopper 2 enters the cylinder 1 first, and then the magnetic attraction component 3 is also driven by the pulling mechanism 4 to move out of the cylinder 1.

[0043] During this process, the iron powder adsorbed on the magnetic rod 302 is blocked by the inside of the cylinder 1, is scraped off, falls into the guide hopper 2, and is then transferred out through the guide hopper 2.

[0044] After the iron powder is cleaned, the pulling mechanism 4 is released, and the magnetic suction component 3 and the guide hopper 2 automatically reset. The magnetic suction component 3 is placed horizontally inside the cylinder 1, and the guide hopper 2 is flush with the inner wall of the cylinder 1, without intruding into the cylinder 1, and can block the opening of the cylinder 1 through the guide hopper 2.

[0045] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
