Description

Technical Field

[0001] This utility model relates to the field of material screening technology, and in particular to a quartz sand magnetic separation device. Background Technology

[0002] The main component of quartz sand is silicon dioxide, but natural quartz sand is often mixed with magnetic minerals such as iron and titanium (such as hematite, magnetite, ilmenite, etc.) and iron oxides. These impurities will significantly reduce the purity of quartz sand and affect its performance. Magnetic separation of quartz sand is mainly to remove magnetic impurities and improve the purity and quality of quartz sand. In existing technologies, when performing magnetic separation on quartz sand, magnetic impurities are typically adsorbed by a rotating drum with built-in magnetic components as the quartz sand flows. When the drum rotates to a position where there is no magnetic adsorption, the magnetic impurities on the drum fall off and are collected. However, the time the quartz sand spends passing through the magnetic components is too short, and the quartz sand directly impacts the drum surface as it passes through, which may knock off the magnetic impurities on the drum. This may result in incomplete adsorption of magnetic impurities in the quartz sand, requiring secondary magnetic separation. This not only affects production efficiency but also increases production costs. On the other hand, if stronger magnetic components are used, since existing technologies mainly use electromagnets, this would lead to increased electricity costs, which is not conducive to reducing production costs. Utility Model Content

[0003] In view of the shortcomings of the above-mentioned prior art, this application provides a quartz sand magnetic separation device, which increases the time that quartz sand passes through the magnetic component, improves the screening effect of magnetic impurities, and has strong practicality.

[0004] To achieve the above objectives, the present invention employs the following technology: A quartz sand magnetic separator includes: a frame, a feeding assembly, and a magnetic separation assembly.

[0005] The feeding assembly includes a feeding frame located in the frame body. The feeding frame is equipped with a partition, which includes a vertical section and an arc-shaped section connected to the lower end of the vertical section. The center of the arc-shaped section is located at the center of the feeding frame. The lower end of the feeding frame is equipped with a downwardly inclined guide plate. There is a gap between the guide plate and the lower end of the partition for guiding the flow of quartz sand. The magnetic separation assembly includes a rotating drum located inside the arc-shaped section and rotating around its own axis. An electromagnet is installed inside the rotating drum. The electromagnet has an arc-shaped cross-section, and both ends of the cross-section are located outside the arc-shaped section and the guide plate.

[0006] Furthermore, a horizontal plate is provided at the lower end of the guide plate, and a vibrating plate is provided inside the horizontal plate. The vibrating plate is inverted L-shape and has a convex plate at its lower end. The convex plate is sleeved on the support rod, and the upper end of the support rod is connected to the guide plate. A spring is sleeved on the support rod, and the two ends of the spring abut against the convex plate and the guide plate respectively, and are always in a compressed state. One of the convex plates is connected to the power output end of the vibrating device, and the vibrating device is installed in the feeding frame.

[0007] Furthermore, a retaining ring is provided at the lower end of the support rod to abut against the convex plate.

[0008] Furthermore, the electromagnet is mounted on a support rod, which passes through the rotating drum, feeding frame, and frame in sequence, and is mounted on a bracket, which is then mounted on the frame.

[0009] Furthermore, a connecting ring is provided at the center of both ends of the rotating drum. The connecting ring passes through the feeding frame and is rotatably mounted on the frame. A driven gear is installed on the outer wall of the connecting ring. The driven gear meshes with the driving gear. The driving gear is mounted on the transmission shaft. The transmission shaft is rotatably mounted on the frame, and one end is connected to the output end of the first power device, which is mounted on the frame.

[0010] Furthermore, a side plate is provided on the side of the rotating drum away from the partition. The side plate is inclined and its lower end is installed on the feeding frame. Both the feeding frame and the side of the frame are provided with outlets, and the outlets are aligned with the top surface of the side plate.

[0011] Furthermore, a rotating roller is provided above the side plate, and a brush is provided around the rotating roller. The brush contacts the outer wall of the rotating drum. The rotating roller is installed on a rotating shaft, which passes through the feeding frame and is rotatably installed on the frame. One end of the rotating shaft is connected to the output end of the second power equipment, which is installed on the frame.

[0012] The beneficial effects of this utility model are as follows: by setting a partition in the feeding frame to block the quartz sand, the direct impact on the drum is avoided, thereby preventing the magnetic impurities on the drum from being knocked off, ensuring the magnetic separation effect. Furthermore, the guide plate increases the time that the quartz sand passes through the electromagnet, and the vibrating plate throws the quartz sand upward, further increasing the time that the quartz sand is within the magnetic field range of the electromagnet, thereby improving the adsorption effect on magnetic impurities and ensuring product quality.

[0019] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.

[0020] like Figures 1-5 As shown, this example provides a quartz sand magnetic separation device, including: a frame 100, a feeding assembly 200, and a magnetic separation assembly 300.

[0021] The feeding assembly 200 includes a feeding frame 201 disposed in the frame 100. A partition 202 is provided in the feeding frame 201. The partition 202 includes a vertical section and an arc-shaped section connected to the lower end of the vertical section, with the center of the arc-shaped section located at the center of the feeding frame 201. A downwardly inclined guide plate 203 is provided at the lower end of the feeding frame 201, with a gap between the guide plate 203 and the lower end of the partition 202 for guiding the flow of quartz sand. The magnetic separation assembly 300 includes a rotating drum 301 disposed inside the arc-shaped section and rotating about its own axis. The rotating drum 301 is located above the guide plate 203, and an electromagnet 302 is disposed inside the rotating drum 301. The electromagnet 302 has an arc-shaped cross-section, with both ends located outside the arc section and the guide plate 203. Quartz sand is fed into the feeding frame 201. Under the obstruction of the partition plate 202, the quartz sand falls onto the guide plate 203 and continues to flow downward under its own gravity. When the quartz sand flows to the bottom of the rotating drum 301, the magnetic impurities in the quartz sand are attracted onto the rotating drum 301 by the attraction of the electromagnet 302. They rotate with the rotating drum 301 until the magnetic impurities are located outside the area of ​​the electromagnet 302. At this time, the magnetic impurities will slide down under their own gravity and be collected.

[0022] Specifically, a horizontal plate 204 is provided at the lower end of the guide plate 203, and a vibrating plate 205 is provided inside the horizontal plate 204. The vibrating plate 205 is inverted L-shape, and a protruding plate 206 is provided at its lower end. The protruding plate 206 is sleeved on the support rod 207, and the upper end of the support rod 207 is connected to the guide plate 203. A spring 208 is sleeved on the support rod 207. The two ends of the spring 208 abut against the protruding plate 206 and the guide plate 203 respectively, and are always in a compressed state to reduce the impact on other components during the up-and-down vibration of the vibrating plate 205. One of the protruding plates... Plate 206 is connected to the power output end of the vibrating device. The vibrating device is installed in the feeding frame 201. The vibrating device can adopt an electromagnetic vibration mechanism, a starting vibration mechanism, or a cam mechanism to realize the up-and-down shaking of the vibrating plate 205. When the quartz sand flows to the bottom of the guide plate 203, the up-and-down shaking of the vibrating plate 205 throws the quartz sand upward, thereby increasing the time that the quartz sand stays below the electromagnet 302, so that magnetic impurities have more time to be adsorbed on the rotating drum 301, thereby improving the adsorption effect of magnetic impurities.

[0023] Specifically, the lower end of the support rod 207 is provided with a retaining ring, which is used to abut against the convex plate 206 to prevent the vibrating plate 205 from falling off.

[0024] Specifically, the electromagnet 302 is mounted on the support rod 303, which passes through the rotating drum 301, the feeding frame 201, and the frame 100 in sequence, and is mounted on the bracket 101. The bracket 101 is mounted on the frame 100 to support the electromagnet 302.

[0025] Specifically, each end of the rotating drum 301 has a connecting ring 304 at its center. The connecting ring 304 passes through the feeding frame 201 and is rotatably mounted on the frame 100. A driven gear 305 is mounted on the outer wall of the connecting ring 304. The driven gear 305 meshes with the driving gear 306. The driving gear 306 is mounted on the transmission shaft 307, which is rotatably mounted on the frame 100 and has one end connected to the output end of the first power device. The first power device is mounted on the frame 100 and can be a motor or the like. During magnetic separation, the first power device drives the transmission shaft 307 to rotate. Under the meshing transmission of the driven gear 305 and the driving gear 306, the rotating drum 301 will rotate synchronously, thereby transferring the magnetic impurities adsorbed on the rotating drum 301. Furthermore, under the action of the partition plate 202, the direct impact of the quartz sand on the rotating drum 301 is also avoided, ensuring that the magnetic impurities can be smoothly transferred away.

[0026] Specifically, a side plate 308 is provided on the side of the rotating drum 301 away from the partition 202. The side plate 308 is inclined and its lower end is installed on the feeding frame 201. The feeding frame 201 and the frame body 100 are provided with outlets on their sides, and the outlets are aligned with the top surface of the side plate 308. When the magnetic impurities on the rotating drum 301 are rotated to an area outside the electromagnet 302, they will fall onto the side plate 308 under their own gravity and flow out and be collected from the outlet.

[0027] Specifically, to reduce dust residue on the rotating drum 301 and prevent it from affecting the adsorption of magnetic impurities, a rotating roller 309 is provided above the side plate 308. A brush is provided around the rotating roller 309, and the brush contacts the outer wall of the rotating drum 301. The rotating roller 309 is mounted on a rotating shaft 310, which extends out of the feeding frame 201 and is rotatably mounted on the frame 100. One end of the rotating shaft 310 is connected to the output end of a second power device, which is mounted on the frame 100. The second power device can be a motor or other equipment. During the rotation of the rotating drum 301, the brush can brush off the dust on the rotating drum 301, and the second power device drives the rotating shaft 310 to rotate, which in turn drives the rotating roller 309 to rotate. The rotation direction of the rotating roller 309 is the same as the rotation direction of the rotating drum 301, so that the dust on the rotating drum 301 can be thrown upward and fall onto the side plate 308, preventing the dust from directly mixing with the magnetically separated quartz sand downward.

[0028] Since the above are merely preferred embodiments of this utility model and are not intended to limit this utility model, it is obvious that those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
