Description

Technical Field

[0001] This invention belongs to the field of quartz sand processing technology, and particularly relates to a device for circulating iron removal from quartz sand. Background Technology

[0002] Iron removal from quartz sand refers to removing iron impurities from quartz sand to improve its purity and quality. Iron impurities in quartz sand mainly include hematite, limonite, magnetite, and goethite. These impurities affect the usability and quality of quartz sand. Therefore, iron removal technology is crucial for ensuring the purity of quartz sand and improving economic efficiency. However, during the iron removal process, the quartz sand is often mixed together. Using magnets for iron removal can easily result in the magnets becoming saturated with iron slag, leading to a decrease in the iron removal effect. This paper proposes a circulating iron removal device that can significantly improve the iron removal effect. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a device for circulating iron removal from quartz sand, thus solving the aforementioned problems.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a circulating iron removal device for quartz sand, comprising a frame, and further comprising: a hopper, a channel, a plastic cover, a magnet, and a slide rod. Two hoppers are symmetrically fixedly connected to both sides of the frame. Multiple channels are staggered on both sides of the hoppers, and multiple plastic covers penetrate the channels. The edges of the plastic covers should have a certain distance from the inner frame of the channels. The magnets are inserted into the plastic covers, and anti-slip damping strips are provided at the connection between the magnets and the plastic covers.

The distance between the two baffles is the same as the width of the plastic cover, and the distance between the two baffles is greater than the width of the magnet block. A guide plate is inclinedly provided below each of the multiple magnet blocks. The guide plate is fixedly connected to the hopper, and the two guide plates on the same side have opposite inclination directions to guide the iron slag on them.

[0007] A further technical solution: one side of each of the multiple magnet blocks is threaded onto a lead screw, the multiple lead screws are rotatably connected to the hopper, and the initial positions of two magnet blocks on the same side on the lead screw are opposite. Any of the lead screws on the same side is fixedly connected to the output shaft of the motor, and the motor is fixedly connected to the frame.

[0008] A further technical solution: pulleys are fixedly connected to both lead screws on the same side, and the two pulleys cooperate with each other to be connected to the belt drive.

There is a certain distance between the screen plate and the bottom plate. The guide tube B is fixedly connected to the screen plate, and the guide tube A is fixedly connected to the shaft. The openings of the guide tube B and the guide tube A face the two conveyor belts respectively.

[0013] Beneficial effects

[0014] This invention provides a device for circulating iron removal from quartz sand, which has the following advantages compared with the prior art:

[0015] Beneficial effects:

[0016] 1. When the quartz sand falls evenly into the hopper, it is intercepted by the upper plastic cover. Simultaneously, because the magnet is located inside the plastic cover, the iron impurities in the quartz sand are adsorbed onto the plastic cover due to the magnetism of the magnet. Furthermore, because the surface of the plastic cover that contacts the quartz sand is sloped, and the staggered arrangement of the plastic covers effectively turbulent the quartz sand, it can slide down the slope onto the next layer of plastic cover, thus performing multi-stage screening to increase the removal accuracy of the iron slag. As the quartz sand slides down the slope of the plastic cover to the next layer, when the plastic cover has adsorbed multiple layers of impurities, the adsorption effect of the top layer of iron slag weakens, making it easier for the iron slag to be carried away by the quartz sand. Therefore, the multi-layered plastic cover effectively increases the adsorption efficiency of the iron slag. As a result, the fault tolerance rate is increased; after a period of time, the user should start the motor, so that the screw fixedly connected to the motor output shaft starts to rotate. At this time, the magnet starts to drive the plastic cover to slide synchronously, so that the two plastic covers in the hopper gradually detach from the discharge hopper, thereby avoiding too much iron slag on the plastic cover, which would prevent it from continuing to attract iron slag. At the same time, during the sliding process of the magnet, the magnet can pass through the two baffles, but the plastic cover will be blocked by the baffles, so that the plastic cover stops sliding with the magnet. At this time, the magnet gradually slides out of the plastic cover, so that the iron slag attracted to the plastic cover, after losing the magnetic effect of the magnet, begins to fall from the plastic cover to the guide plate below it. At the same time, since the guide plate has a slope, it can guide the iron slag to the side of the hopper.

[0017] 2. Simultaneously, when the motor starts, the two lead screws begin to rotate synchronously under the action of the belt. Since the initial positions of the magnet blocks are opposite and the threads of the two lead screws on the same side are opposite, the two lead screws begin to slide towards each other. As the magnet blocks detach from the hopper, the lower magnet blocks and plastic covers begin to enter the hopper, thus taking over from the upper magnet blocks and plastic covers to continue the adsorption of iron slag. In this way, the adsorption of iron slag is carried out in a cycle through the two sets of magnet blocks and plastic covers.

[0018] 3. The user pours the quartz sand evenly onto the screen plate, then starts the vibrating motors on both sides. When the eccentric blocks installed at both ends of the motor output shaft rotate at high speed, the centrifugal force generated by the eccentric blocks forms a periodic excitation force. This force is further amplified by the springs fixed between the base and the connecting plate. Simultaneously, because the frame is tilted at a certain angle, the quartz sand begins to slide smoothly down the screen plate. Since the screen plate has multiple identical sieve holes, smaller particles of quartz sand can pass through the sieve holes and fall onto the bottom plate, thus classifying the quartz sand. This increases the accuracy of iron removal. At the same time, the quartz sand particles on the screen and the bottom plate are guided by guide pipes B and A to the conveyor belts on both sides. Under the continuous vibration of the vibrating motor, the quartz sand is evenly spread on the conveyor belt. During this process, the user starts motor A, which causes the shaft fixedly connected to its output shaft to start rotating. At this time, the two rollers cooperate to drive the conveyor belt to rotate at a constant speed. Therefore, when the quartz sand falls onto the conveyor belt, it can be spread on the conveyor belt with a relatively thin thickness and then circulated to the hopper for iron removal.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0026] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0027] Please see Figure 1 as well as Figure 5 According to one embodiment of the present invention, a circulating iron removal device for quartz sand includes a frame 101, and further includes: a hopper 201, a channel 202, a plastic cover 203, a magnet 204, and a slide rod 205. Two hoppers 201 are symmetrically fixedly connected to both sides of the frame 101. Multiple channels 202 are staggered on both sides of the hoppers 201, and multiple plastic covers 203 penetrate through the channels 202. The edges of the plastic covers 203 should have a certain distance from the inner frame of the channels 202. The magnet 204 is inserted into the plastic cover 203, and an anti-slip damping strip is provided at the connection between the magnet 204 and the plastic cover 203. The slide rod 205 is fixedly connected to the hopper 201, and both the magnet 204 and the plastic cover 203 are slidably connected to the slide rod 205.

[0028] And sorting component 3, used to make the quartz sand particles fall evenly into the hopper 201.

[0029] Please see Figure 4 as well as Figure 5 Specifically, each of the multiple plastic covers 203 has two baffles 206 symmetrically arranged on one side. The distance between the two baffles 206 is the same as the width of the plastic cover 203, and the distance between the two baffles 206 is greater than the width of the magnet block 204. Each of the multiple magnet blocks 204 has a guide plate 208 inclined below it. The guide plate 208 is fixedly connected to the hopper 201, and the two guide plates 208 on the same side have opposite inclination directions to guide the iron slag on them.

[0030] Please see Figure 4 Specifically, one side of each of the multiple magnet blocks 204 is threaded onto a lead screw 209. The multiple lead screws 209 are rotatably connected to the hopper 201. The initial positions of two magnet blocks 204 on the same side on the lead screw 209 are opposite. Any of the lead screws 209 on the same side is fixedly connected to the output shaft of the motor 2003. The motor 2003 is fixedly connected to the frame 101.

[0031] Please see Figure 4 Specifically, pulleys 2001 are fixedly connected to the two lead screws 209 on the same side, and the two pulleys 2001 cooperate with each other to drive the belt 2002.

[0032] In this embodiment of the invention, when the quartz sand falls evenly into the hopper 201, it is intercepted by the upper plastic cover 203. Simultaneously, because the magnet 204 is located inside the plastic cover 203, the iron impurities in the quartz sand are adsorbed onto the plastic cover 203 under the magnetic effect of the magnet 204. Furthermore, since the surface of the plastic cover 203 used to contact the quartz sand is inclined, and the staggered arrangement of the plastic covers 203 can effectively turbulent the quartz sand, the quartz sand can slide down the inclined surface onto the next layer of plastic cover 203, thus performing multi-stage screening to increase the removal accuracy of the iron slag. During the process of the quartz sand sliding down the inclined surface of the plastic cover 203 to the next layer, when the plastic cover 203 has adsorbed multiple layers of impurities, the adsorption effect of the uppermost layer of iron slag will weaken, making it easier for the quartz sand to carry it down. Therefore, the multi-layered arrangement of the plastic covers 203 can effectively increase the adsorption effect on the iron slag and increase the tolerance rate. After a period of time... The user should start the motor 2003, which will cause the lead screw 209 fixedly connected to the output shaft of the motor 2003 to start rotating. At this time, the magnet 204 will start to drive the plastic cover 203 to slide synchronously, so that the two plastic covers 203 in the hopper 201 will gradually detach from the discharge hopper 201, thereby avoiding too much iron slag on the plastic cover 203, which will prevent it from continuing to attract iron slag. At the same time, during the sliding process of the magnet 204, the magnet 204 can pass through the two baffles 206, but the plastic cover 203 will be blocked by the baffles 206, so that the plastic cover 203 stops sliding with the magnet 204. At this time, the magnet 204 gradually slides out of the plastic cover 203, so that the iron slag attracted to the plastic cover 203 will fall from the plastic cover 203 to the guide plate 208 below it after losing the magnetic effect of the magnet 204. At the same time, since the guide plate 208 has a slope, it can guide the iron slag to the side of the hopper 201.

[0033] Simultaneously, when the motor 2003 starts, the two lead screws 209 begin to rotate synchronously under the action of the belt 2002. Since the initial positions of the magnet blocks 204 are opposite and the thread directions of the two lead screws 209 on the same side are opposite, the two lead screws 209 begin to slide towards each other. As the magnet blocks 204 detach from the hopper 201, the lower magnet blocks 204 and the plastic cover 203 begin to enter the hopper 201, thereby taking over from the upper magnet blocks 204 and the plastic cover 203 to continue the adsorption of iron slag. Thus, the adsorption of iron slag is carried out in a cycle through the two sets of magnet blocks 204 and plastic cover 203.

[0034] Please see Figure 5 Specifically, the sorting component 3 includes a shaft 301, a roller 302 and a conveyor belt 303. Multiple shafts 301 are symmetrically rotatably connected to the frame 101, and multiple rollers 302 are respectively fixedly connected to the shafts 301. Two rollers 302 on the same side cooperate with each other and are rotatably connected to the conveyor belt 303.

[0035] And a screening component, used to ensure that the screened quartz sand falls evenly onto the conveyor belt 303.

[0036] Please see Figure 5 Specifically, the two conveyor belts 303 are driven by their respective motors A304, and the output shaft of the motor A304 is fixedly connected to either shaft 301.

[0037] Please see Figure 1 , Figure 2 as well as Figure 3 Specifically, the screening assembly includes a frame 308, a screen plate 309, a bottom plate 3001, a guide tube B3004, and a guide tube A3003. The screen plate 309 and the bottom plate 3001 are fixedly connected between two frames 308, and the screen plate 309 is above the bottom plate 3001, with a certain distance between them. The guide tube B3004 is fixedly connected to the screen plate 309, and the guide tube A3003 is fixedly connected to the shaft 301. The openings of the guide tubes B3004 and A3003 face the two conveyor belts 303 respectively.

[0038] Please see Figure 1 Specifically, the mesh plate 309 is symmetrically fixedly connected to the two sides of the connecting plate 307, and a spring 306 is fixedly connected to the connecting plate 307. The other end of the spring 306 is fixedly connected to the base 305, and the frame 308 is inclinedly arranged on the base 305. The base 305 is fixedly connected to the frame 101.

[0039] In this embodiment of the invention, the user pours quartz sand evenly onto the screen plate 309, and then starts the vibrating motors 3005 on both sides. When the eccentric blocks installed at both ends of the output shaft of the vibrating motor 3005 rotate at high speed, the centrifugal force generated by the eccentric blocks forms a periodic excitation force, which can increase the vibration effect through the springs 306 fixed between the base 305 and the connecting plate 307. At the same time, since the frame 308 is tilted to a certain angle, the quartz sand begins to slide smoothly down the screen plate 309. Since the screen plate 309 has multiple sieve holes of the same size, the smaller quartz sand particles can pass through the sieve holes of the screen plate 309 and fall onto the bottom plate 3001, thereby classifying the quartz sand. To increase the precision of iron removal, the quartz sand particles on the mesh plate 309 and the bottom plate 3001 are guided by the guide pipes B3004 and A3003 to the conveyor belts 303 on both sides. Under the continuous vibration of the vibrating motor 3005, the quartz sand is evenly spread on the conveyor belt 303. During this process, the user starts the motor A304, which causes the shaft 301, which is fixedly connected to its output shaft, to start rotating. At this time, the two rollers 302 cooperate with each other to drive the conveyor belt 303 to rotate at a uniform speed. Therefore, during the process of the quartz sand falling onto the conveyor belt 303, the quartz sand can be spread on the conveyor belt 303 with a relatively thin thickness and then circulated to the hopper 201 for iron removal.

[0040] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0041] The term "fixed connection" as used in this application refers to a connection in which parts or components are fixed without any relative movement. This includes both detachable and non-detachable connections.

[0042] (1) Detachable connection: The components are fixed together using screws, splines, wedges, etc. This type of connection can be disassembled during maintenance without damaging the parts. However, the specifications of the connecting parts used must be correct (such as the length of the bolts, keys, wedges) and properly tightened.

[0043] (2) Non-removable connections: These mainly refer to welding, riveting, and tenon joints. Since disassembly requires forging, sawing, or oxyacetylene cutting for repair or replacement, the parts generally cannot be reused.

[0044] The sliding connection referred to in this application means that the component can slide along a linear trajectory, and the hinge referred to in this application means that the component can rotate along an axial constraint.

[0045] In some cases, the sliding connection and hinge referred to in this application may also be damped, enabling the component to maintain in the desired position.
