Description

Technical Field

[0001] This utility model relates to the technical field of white fused alumina production equipment, and in particular to a white fused alumina iron removal screening device. Background Technology

[0002] White fused alumina is a type of artificial abrasive, containing over 99% aluminum oxide and small amounts of iron oxide and silicon oxide, and is white in color. Its key characteristics are small crystal size and impact resistance. When processed and crushed using an autogenous mill, the particles are mostly spherical with clean, dry surfaces, easily combining with binders. However, iron removal is necessary during production. Existing white fused alumina iron removal devices typically use a magnetic mesh laid below a screen. However, due to the perforated mesh structure, the magnetic mesh has limited effectiveness in adsorbing iron impurities. With the impact of the material during screening, the iron impurities adsorbed by the magnetic mesh are relatively easily washed away by the material, thus affecting the iron removal effect. Therefore, this application proposes a white fused alumina iron removal screening device. Utility Model Content

[0003] To address the above situation and overcome the shortcomings of existing technologies, this utility model provides a white corundum iron removal screening device. The technical solution it provides includes a housing, characterized in that a discharge port and two large inclined slides symmetrically arranged about the discharge port are integrally arranged at the bottom of the housing. The large inclined slides are made of aluminum alloy. A support frame is fixedly connected to the inner wall of the housing, and a screen is fixedly connected to the upper end of the support frame. Multiple evenly distributed electromagnets are fixedly connected to the lower end of each of the large inclined slides. A mounting frame is fixedly connected to the large inclined slide on the right side, and a vibration motor is fixedly connected to the mounting frame. A reciprocating drive device, coaxially arranged with the discharge port, is arranged on the inner wall of the housing. The reciprocating drive device is connected to two scrapers, which abut against each large inclined slide in a one-to-one correspondence. A protective cover, cooperating with the reciprocating drive device, is fixedly connected to the inner wall of the housing. The protective cover has two symmetrically arranged small inclined slides integrally arranged, each corresponding to a large inclined slide. A support assembly is arranged on the outside of the housing.

[0004] Preferably, the reciprocating drive device includes a reciprocating screw rotatably connected to the inner wall of the housing, a longitudinal shaft arranged parallel to the reciprocating screw fixedly connected to the inner wall of the housing, the upper end of the reciprocating rod threadedly connected to the reciprocating screw, the lower end of the reciprocating rod slidably connected to the longitudinal shaft, the middle part of the connecting rod integrally connected to the reciprocating rod, the two ends of the connecting rod being fixedly connected to the two scrapers respectively, and a drive motor for driving the reciprocating screw fixedly connected to the front end of the housing, with both the reciprocating screw and the longitudinal shaft located directly below the protective cover.

[0005] Preferably, the support assembly includes four top blocks arranged in a rectangular array and fixedly connected to the outer wall of the shell. Each top block has an upper cylinder fixedly connected to its lower end. Four support legs arranged in a rectangular array are arranged below the shell. Each support leg has a lower cylinder fixedly connected to its upper end. The upper cylinder and the lower cylinder correspond one-to-one. Each upper cylinder has the lower end of a support spring coaxially mounted on it. The lower end of each support spring is coaxially mounted on the lower cylinder on its corresponding side. A reinforcing beam is fixedly connected between the support legs.

[0006] The beneficial effects of this utility model are:

[0007] In use, this application utilizes a large inclined slide in conjunction with an electromagnet to attract iron impurities. Compared to traditional hollow magnetic mesh structures, the large inclined slide significantly improves the resistance to scouring, ensuring better removal of iron impurities. The application uses a vibrating motor to drive the housing and related components such as the screen to vibrate, causing the material to pass through the screen. After passing through the screen, the material slides down the large inclined slide towards the discharge port. During this descent, iron impurities in the material are attracted to the large inclined slide by the electromagnet, and the material is discharged through the discharge port. After the material is discharged and collected, the electromagnet can be de-energized, causing it to lose its magnetism. This removes the iron impurities from the large inclined slide, allowing them to slide down and be discharged through the discharge port. Furthermore, to prevent iron impurities from remaining on the large inclined slide, a reciprocating drive device is provided. Under the action of this device, a scraper cleans the iron impurities from the large inclined slide, allowing them to slide down to the discharge port. Attached Figure Description

[0015] The following is in conjunction with the appendix Figure 1-5 The specific embodiments of this utility model will be described in further detail.

[0016] In the first embodiment, the technical solution is as follows: When in use, the vibration motor 8 can drive the housing 1 and related components such as the screen 5 to vibrate, thereby causing the material with the required composite properties to pass through the screen 5. After passing through the screen 5, the material will slide down the large inclined slide 3 to the discharge port 2. During the sliding process, iron impurities in the material will be attracted to the large inclined slide 3 under the action of the electromagnet 6, and the material will be discharged through the discharge port 2. After the material is discharged and collected, the electromagnet 6 can be de-energized to make it lose its magnetism, and the iron impurities on the large inclined slide 3 will lose their attraction. At this time, the iron impurities will slide down the large inclined slide 3 and be discharged through the discharge port 2. Furthermore, in order to avoid iron impurities from being stuck on the large inclined slide 3, a reciprocating drive device 9 is provided. Under the action of the reciprocating drive device 9, the scraper 10 can clean the iron impurities on the large inclined slide 3, so that they slide down the large inclined slide 3 to the discharge port 2. This application uses a large inclined slide 3 in conjunction with an electromagnet 6 to adsorb iron impurities. Compared with the traditional hollow magnetic mesh, the large inclined slide 3 has a much better effect in resisting erosion and can better ensure the removal of iron impurities.

[0017] In Example 2, based on Example 1, specifically, in use, a screen 5 is arranged inside the housing 1 via a support frame 4, and a vibration motor 8 is arranged on the large inclined slide 3. The white corundum material to be screened and de-ironized is placed on the screen 5. The vibration motor 8 is then started, causing the housing 1 and the screen 5 to vibrate, thereby screening the white corundum material on the screen 5. During the operation of the vibration motor 8, to prevent damage to the housing 1 and support components due to vibration, thus affecting their service life, an upper cylinder 19 and a lower cylinder 21 are arranged in the support components. The upper cylinder 19, lower cylinder 21, and support spring 22 achieve an elastic connection between the top block 18 and the support leg 20. Therefore, during the vibratory screening process, the housing 1 can operate safely to the maximum extent, ensuring normal operation and effectiveness of the vibratory screening. To ensure the stability of the support leg 20, a reinforcing beam 23 is arranged.

[0018] During the vibrating screening process, the electromagnet 6 should be energized to give it a certain magnetic strength, thereby ensuring that the electromagnet 6 can adsorb iron impurities through the large inclined slide 3. Under the action of the vibrating motor 8, which is fixedly connected to the mounting frame 7, the screen 5 vibrates and screens the white fused alumina material. The white fused alumina material that meets the requirements, along with the iron impurities, will pass through the screen 5 and fall onto the large inclined slide 3. The large inclined slide 3 is arranged at an angle, so the white fused alumina material falling on it will slide down to the discharge port 2, while the iron impurities will be adsorbed onto the large inclined slide 3 under the magnetic force of the electromagnet 6. After the white fused alumina material is discharged from the discharge port 2 and collected, the iron impurities adsorbed on the large inclined slide 3 can be processed.

[0019] When processing impurities adsorbed on the large inclined slide 3, the electromagnet 6 should be de-energized to demagnetize it. This will cause the iron impurities on the large inclined slide 3 to lose their magnetic attraction, allowing them to flow along the slide 3 towards the discharge port 2 for collection. The large inclined slide 3 is made of aluminum alloy, which prevents the electromagnet 6 from becoming magnetized during energization, thus avoiding interference with the processing of iron impurities. Furthermore, during the process of handling iron impurities, in order to prevent iron impurities from adhering and remaining on the large inclined slide plate 3, the drive motor 17 of the reciprocating drive device 9 can be started. The start of the drive motor 17 will drive the reciprocating screw 13 to rotate. The rotation of the reciprocating screw 13 will drive the reciprocating rod 15 threadedly connected to it. The reciprocating rod 15 is slidably connected to the longitudinal axis 14. Therefore, under the drive of the reciprocating screw 13, the reciprocating rod 15 will move back and forth along the longitudinal axis 14. Consequently, the connecting rod 16 fixedly connected to the reciprocating rod 15 and the scraper 10 fixedly connected to the connecting rod 16 will move back and forth accordingly. During the reciprocating movement of the scraper 10, the iron impurities remaining on the large inclined slide plate 3 can be cleaned so that they can slide towards the discharge port 2.

[0020] In Example 3, based on Example 2, the reciprocating screw 13 and the longitudinal shaft 14 are both located directly below the protective cover 11 to prevent material from intruding into the connection between the reciprocating screw 13 and the longitudinal shaft 14 and the reciprocating rod 15, thus affecting their normal operation. Furthermore, the protective cover 11 is integrally equipped with small inclined slides 12 that correspond one-to-one with the large inclined slide 3. Therefore, after passing through the screen 5, the material corresponding to the discharge port 2 can first fall onto the small inclined slides 12, and then slide down onto the large inclined slide 3 for iron removal, preventing the material from directly passing through the discharge port 2 and ensuring the iron removal effect.
