A process for removing impurities and reducing titanium in high-purity quartz sand and equipment for production

Abstract

The present invention relates to the technical field of quartz sand purification, specifically to a high-purity quartz sand impurity removal and titanium reduction process and production equipment, including a base, wherein a round table is fixedly installed in the middle of the upper end of the base. The four magnetic plates can be intermittently away from the inner side of the spiral chute, and the four magnetic plates will also flip 180 degrees during the process, so that the plastic plates on the four magnetic plates face the inner side of the spiral chute, so that the particles with larger specific gravity are no longer attracted, which helps the particles with larger specific gravity to move with the water flow and fall out of the spiral chute. When the four magnetic plates continue to be with the inner side of the spiral chute, they will continue to attract the particles with larger specific gravity. Through intermittent magnetic attraction, excessive aggregation of particles with larger specific gravity is avoided, which helps the particles with larger specific gravity to leave the area near the four magnetic plates faster in the spiral groove of the spiral chute with the water flow, thereby optimizing the particle discharge process.

Description

Technical Field

[0001] The present invention relates to the technical field of quartz sand purification, and particularly to a process for removing impurities and reducing titanium content in high-purity quartz sand and production equipment therefor. Background Art

[0002] In the process of removing impurities and reducing titanium content in high-purity quartz sand, a spiral chute is often used, which is an effective gravity separation equipment. The working principle of the spiral chute is based on the specific gravity difference of minerals. Through the combined action of water flow, mineral gravity, and the friction between the mineral particles and the bottom surface of the chute, the minerals are settled according to their specific gravity and distributed in different zones within the chute. Specifically, the pulp (a suspension containing mineral particles such as quartz sand) is fed into the upper central position of the spiral chute. Under the combined action of gravity and centrifugal force, the particles in the pulp move downward along the spiral chute. Particles with a larger specific gravity (such as metal particle impurities like titanium) will be thrown towards the inner edge within the spiral chute, while particles with a smaller specific gravity (such as quartz sand particles) will be thrown towards the outer edge. An intercepting section is provided at the tail of the spiral chute to separate and collect particles with a larger specific gravity from those with a smaller specific gravity, thereby removing impurities and reducing titanium content in the high-purity quartz sand.

[0003] However, relying solely on gravity and centrifugal force to separate metal particle impurities such as titanium from quartz sand particles according to the specific gravity difference, the separation efficiency is not high enough. When the metal particle impurities such as titanium in the pulp flow spirally downward in the spiral chute, they do not have a tendency to move actively towards the inner edge of the spiral chute, and some metal particle impurities such as titanium are likely to be mixed in the quartz sand particles. It is often necessary to circulate the pulp in the spiral chute many times to more thoroughly separate the metal particle impurities such as titanium from the quartz sand particles. At the same time, after the spiral chute finishes processing the quartz sand pulp, some particle impurities often adhere to the inside of the chute. Due to its complex spiral structure, it is difficult to completely remove the adhered particle impurities subsequently, which will affect the normal use of the spiral chute over time. Summary of the Invention

[0014] Preferably, the present invention also discloses a process for removing impurities and reducing titanium in the production of high-purity quartz sand, including the following steps:

[0015] S1: First, the quartz sand slurry enters from the top of the existing conveying system along the spiral chute, and then flows spirally downward along the spiral groove of the spiral chute. The particles with a larger specific gravity will be thrown towards the inner edge in the spiral groove, and the particles with a smaller specific gravity will be thrown towards the outer edge in the spiral groove;

[0016] S2: Start the motor. The motor will drive the rotating disc, the connecting cylinder, the four concave plates, the four plastic plates, the four magnetic plates, etc. to rotate together. The four magnetic plates will rotate while fitting on the inner side surface of the spiral chute. Under the action of magnetic attraction, the particles with a larger specific gravity have a tendency to be passively close to the inner edge of the spiral chute, which can improve the separation efficiency and reduce the number of times the quartz sand slurry circulates in the spiral chute;

Then, it will no longer attract the particles with a larger specific gravity, which helps the particles with a larger specific gravity move with the water flow and fall out of the spiral chute. When the four magnetic plates continue to contact the inner side of the spiral chute, they will continue to attract the particles with a larger specific gravity. Through intermittent magnetic attraction, it is avoided that the particles with a larger specific gravity gather excessively, which helps the particles with a larger specific gravity move away from the area near the four magnetic plates faster with the water flow in the spiral groove of the spiral chute, optimizing the particle discharge process;

[0018] S4: Through the mutual cooperation of the elastic component, the annular frame, the first triangular block and the second triangular block, the spiral chute can also maintain vertical jitter, further avoiding particle aggregation, improving the smoothness of the quartz sand slurry flow, and further improving the particle separation effect;

[0019] S5: Through the mutual cooperation of the cleaning mechanism and the fixing part, it is convenient to thoroughly clean the spiral groove of the spiral chute from top to bottom, and the cleaning method is spiral downward and adapted to the shape of the spiral chute, avoiding affecting the normal use of the spiral chute.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. Through the mutual cooperation of the base, the frustum, the elastic component, the fixing plate, the spiral chute, the annular frame, the first triangular block, the second triangular block, the motor, the turntable, the connecting cylinder, the concave plate, the magnetic plate, the flipping mechanism, the plastic plate, the adjusting mechanism, the expanding and contracting component, the cleaning mechanism and the fixing part, the four magnetic plates can intermittently move away from the inner side of the spiral chute, and during the process, the four magnetic plates will also flip 180 degrees, making the plastic plates on the four magnetic plates face the inner side of the spiral chute. Then, it will no longer attract the particles with a larger specific gravity, which helps the particles with a larger specific gravity move with the water flow and fall out of the spiral chute. When the four magnetic plates continue to contact the inner side of the spiral chute, they will continue to attract the particles with a larger specific gravity. Through intermittent magnetic attraction, it is avoided that the particles with a larger specific gravity gather excessively, which helps the particles with a larger specific gravity move away from the area near the four magnetic plates faster with the water flow in the spiral groove of the spiral chute, optimizing the particle discharge process.

[0022] 2. The spiral chute can also maintain vertical jitter, further avoiding particle aggregation, improving the smoothness of the quartz sand slurry flow, and further improving the particle separation effect.

[0023] 3. It is convenient to thoroughly clean the spiral groove of the spiral chute from top to bottom, and the cleaning method is spiral downward and adapted to the shape of the spiral chute, avoiding affecting the normal use of the spiral chute. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Example 1: Please refer to Figure 1 - Figure 11 , a high-purity quartz sand impurity removal and titanium reduction production equipment, including a base 7, a round table 6 is fixedly installed in the middle of the upper end of the base 7, and the upper end of the base 7 is elastically connected with a fixed plate 4 through an elastic component at the edges of the two sides of the base 7, a spiral chute 8 is fixedly connected between the two fixed plates 4, a motor 9 is fixedly installed on the upper end of the round table 6, a turntable 11 is fixedly connected to the output shaft end of the motor 9, a connecting tube 2 is fixedly connected to the middle of the upper end of the turntable 11, and four concave plates 29 are slidably arranged in a circular array around the center of the turntable 11, and magnetic plates 3 are rotatably connected between the upper and lower horizontal walls of the four concave plates 29, a turning mechanism is arranged between the four magnetic plates 3 and the output shaft of the motor 9, and the four magnetic plates 3 are fixedly connected to the wall surface of the corresponding connecting tube 2 with plastic plates 32, an adjusting mechanism is arranged between the four concave plates 29 and the connecting tube 2, a cleaning mechanism is arranged on the connecting tube 2, and the wall surfaces of the four magnetic plates 3 away from the connecting tube 2 are all in contact with the inner side surface of the spiral chute 8.

[0038] The upper end of the turntable 11 is provided with four slide grooves 19 in a circular array around the center thereof, and the lower ends of the four concave plates 29 are fixedly connected with T-shaped blocks 20 away from the magnetic plate 3, and the vertical sections of the four T-shaped blocks 20 are respectively slidably matched with the four slide grooves 19, and the horizontal sections of the four T-shaped blocks 20 are all in contact with the lower end of the turntable 11; specifically, by providing the slide grooves 19 and the T-shaped blocks 20, the sliding connection between the concave plates 29 and the turntable 11 can be achieved, and the concave plates 29 will only slide toward the center of the turntable 11 or away from the center of the turntable 11 at the upper end of the turntable 11, and the concave plates 29 will not be separated from the turntable 11. At the same time, when the turntable 11 rotates, the concave plates 29 can be driven to rotate together by the T-shaped blocks 20.

[0039] The flipping mechanism includes a rotating shaft 21 and a connecting plate 25. The rotating shaft 21 is fixedly connected to the lower end of the magnetic plate 3, and the lower end of the rotating shaft 21 movably passes through the concave plate 29, and the lower end of the rotating shaft 21 is fixedly connected to a gear 23, and a torsion spring 22 is fixedly connected between the upper end of the gear 23 and the lower end of the concave plate 29. The torsion spring 22 is slidably sleeved on the outer wall of the rotating shaft 21, one end of the connecting plate 25 is fixedly connected to the output shaft of the motor 9, and the other end of the connecting plate 25 is fixedly connected to a toothed plate 24, and the toothed plate 24 is on the movement path of the gear 23.

[0040] The adjusting mechanism includes an electric push rod two 31 and three collars 17. The three collars 17 are slidably sleeved on the outer wall of the connecting cylinder 2 in a linear array from top to bottom. A splicing column 30 is fixedly connected between adjacent two collars 17. A contraction and expansion assembly is provided between each collar 17 and the four concave plates 29. The electric push rod two 31 is fixedly installed on the upper part of the outer wall of the connecting cylinder 2, and the telescopic shaft end of the electric push rod two 31 is fixedly connected to the upper end of the collar 17 at the uppermost position.

[0041] The contraction and expansion assembly includes four connecting rods 18. One ends of the four connecting rods 18 are rotatably connected to the outer wall of the collar 17, and the other ends of the four connecting rods 18 are respectively rotatably connected to the wall surfaces of the four concave plates 29 corresponding to the connecting cylinder 2.

[0042] In this embodiment, the quartz sand slurry is continuously conveyed to the top inlet of the spiral chute 8 by an existing circulating conveying system. Subsequently, the quartz sand slurry will flow spirally downward along the spiral groove of the spiral chute 8. During this period, under the combined action of gravity and centrifugal force, particles with a larger specific gravity (such as metal particle impurities like titanium) will be thrown towards the inner edge in the spiral groove, and particles with a smaller specific gravity (such as quartz sand particles) will be thrown towards the outer edge in the spiral groove. The intercepting section and the collecting section at the tail of the spiral chute 8 will separately collect particles with a larger specific gravity and particles with a smaller specific gravity. This is a well-known prior art and will not be elaborated here.

[0043] Meanwhile, start the motor 9. The motor 9 can drive the turntable 11 to rotate, and the output shaft of the motor 9 can also drive the four connecting plates 25 to rotate together. The four connecting plates 25 can drive the respective connected toothed plates 24 to rotate together. The turntable 11 can also drive the four concave plates 29 to rotate together, and the turntable 11 can also drive the connecting cylinder 2 to rotate. The connecting cylinder 2 can drive the electric push rod two 31, the three collars 17, the two splicing columns 30, and the four connecting rods 18 rotatably connected between each collar 17 and the four concave plates 29 to rotate together. The four concave plates 29 can drive the respective connected magnetic plates 3 and plastic plates 32 to rotate together. The four magnetic plates 3 can drive the respective connected rotating shafts 21, gears 23, and torsion springs 22 to rotate together, and the four magnetic plates 3 rotate while adhering to the inner spiral surface of the spiral chute 8, thereby continuously attracting particles with a larger specific gravity (such as metal particle impurities like titanium). Then, particles with a larger specific gravity (such as metal particle impurities like titanium) tend to passively approach the inner edge of the spiral chute 8, thereby improving the separation efficiency and reducing the number of times the quartz sand slurry circulates in the spiral chute 8.

[0044] In the above process, the electric push rod 2 31 can be started to shorten and then lengthen its telescopic shaft, and in this way, when the telescopic shaft of the electric push rod 2 31 is shortened, a sleeve ring 17 connected thereto and located at the top will be driven to slide up outside the connecting tube 2. Since a splicing column 30 is fixedly connected between two adjacent sleeve rings 17, the three sleeve rings 17 will move up synchronously, and each sleeve ring 17 will drive the four connecting rods 18 to rotate synchronously in a contracted form, so the four concave plates 29 can be driven to move synchronously at the upper end of the turntable 11 toward the center of the turntable 11, and each concave plate 29 will drive the magnetic plate 3 and the plastic plate 32 connected thereto to move together. When each magnetic plate 3 moves, the magnetic plate 3 will first break away from the fit with the inner spiral surface of the spiral chute 8, Then the gear 23 connected under the magnetic plate 3 will move to contact with the corresponding tooth plate 24 and pass through the tooth plate 24, the gear 23 will mesh with the tooth plate 24 and rotate accordingly, the gear 23 will drive the corresponding rotating shaft 21 to rotate, and the gear 23 will twist the torsion spring 22 connected to the concave plate 29, the rotating shaft 21 will drive the corresponding magnetic plate 3 to rotate, because the magnetic plate 3 at this time has been separated from the fit with the inner spiral surface of the spiral chute 8, then the rotation of the magnetic plate 3 is not hindered, until the gear 23 moves to the tail of the tooth plate 24, at this time the gear 23 will also rotate 180 degrees, then the magnetic plate 3 will also flip 180 degrees in the corresponding concave plate 29, so that the plastic plate 32 on the magnetic plate 3 faces the inner spiral surface of the spiral chute 8,

[0045] To sum up, the four magnetic plates 3 will no longer attract particles with a larger specific gravity (such as metal particle impurities such as titanium). On the contrary, when the telescopic shaft of the electric push rod 231 is extended, under the action of the torsion spring 22, the four magnetic plates 3 will turn back and fit with the inner spiral surface of the spiral chute 8, and will continue to attract particles with a larger specific gravity. Through intermittent magnetic attraction, excessive aggregation of particles with a larger specific gravity can be avoided, which helps particles with a larger specific gravity to leave the area near the four magnetic plates 3 faster in the spiral groove of the spiral chute 8 with the water flow, thereby optimizing the particle discharge process.

[0046] Example 2: Please refer to Figure 1 - Figure 3 The present embodiment further explains Example 1, the elastic component includes a square shell 5 and an L-shaped plate 13, the square shell 5 is slidably sleeved at the lower edge of the outer wall of the fixed plate 4, and the lower end of the square shell 5 is fixedly connected to the upper end of the base 7, and the upper edge of the side wall of the square shell 5 corresponding to the motor 9 is fixedly connected with a support plate 39, the L-shaped plate 13 is fixedly connected to the side wall of the fixed plate 4 near the square shell 5, and the horizontal wall of the L-shaped plate 13 is symmetrically fixedly connected with guide columns 16, the lower ends of the two pairs of guide columns 16 are movably passed through the support plate 39, and the outer walls of the two guide columns 16 are slidably sleeved with springs 15, and the two springs 15 are fixedly connected between the L-shaped plate 13 and the support plate 39.

[0047] The lower end of the turntable 11 is fixedly connected to a ring frame 10, and the upper end of the ring frame 10 is fixedly connected to a plurality of triangular blocks 12 in a ring array around its center. The vertical wall of the L-shaped plate 13 is fixedly connected to a triangular block 2 14, and the triangular block 2 14 is located between two adjacent triangular blocks 12.

[0048] In this embodiment, the output shaft of the motor 9 can drive the annular frame 10 to rotate while rotating. The annular frame 10 can drive multiple triangular blocks 12 to rotate together. The rotation of each triangular block 12 will squeeze and push the two triangular blocks 14 upward in turn. When each triangular block 14 moves upward, it will drive the L-shaped plate 13 to move upward. The L-shaped plate 13 will drive the fixed plate 4 to slide upward in the square shell 5, and the L-shaped plate 13 will drive the two guide pillars 16 to slide upward in the support plate 39, and the L-shaped plate 13 will also stretch the two springs 15 connected to the support plate 39. When the triangular block 12 rotates away from the triangular block 14, under the action of the spring 15, the L-shaped plate 13 and the fixed plate 4 will automatically move down and reset.

[0049] To sum up, as the multiple triangular blocks 12 continue to rotate, the two fixed plates 4 will continue to shake in the vertical direction, thereby driving the spiral chute 8 connected between the two fixed plates 4 to continue to shake in the vertical direction, further avoiding the aggregation of particles, improving the smoothness of the flow of quartz sand slurry, and further improving the particle separation effect.

[0050] Example 3: Please refer to Figure 1 , Figure 6 , Figure 7 , Figure 9 and Figure 10 The present embodiment further illustrates the first embodiment, the cleaning mechanism comprises a spring 2 35, a card slot 1 33 and three card slots 2 34, the spring 2 35 is fixedly connected to the inner bottom end of the connecting tube 2, and the upper end of the spring 2 35 is fixedly connected to a sliding column 28, the sliding column 28 slides and fits at the upper edge of the inner wall of the connecting tube 2, and the outer wall of the sliding column 28 is fixedly connected to a card block 36, and a fixing piece is provided between the sliding column 28 and the connecting tube 2, the card slot 1 33 is arranged on the outer wall of the connecting tube 2, and the three card slots 2 34 are respectively arranged at the outer walls of the three collars 17 corresponding to the card slot 1 33, the card block 36 and the card slot 1 33 are slidably matched, and the card block 36 is fixedly connected to the upper edge of the wall surface away from the sliding column 28 with a splicing rod 27, and the end of the splicing rod 27 away from the card block 36 is fixedly installed with an electric push rod 1 26, and the telescopic shaft end of the electric push rod 1 26 is fixedly connected with a scraper 1, and the scraper 1 is located above the spiral chute 8.

[0051] The fixing part includes an electric push rod 38, which is fixedly installed on the outer wall of the connecting tube 2 through an L-shaped seat, and the telescopic shaft end of the electric push rod 38 is fixedly connected to the limiting column 37, and the limiting column 37 is slidably inserted into the inner walls of the connecting tube 2 and the sliding column 28 in turn.

[0052] In this embodiment, the rotation of the connecting tube 2 will also drive the spring 2 35, the sliding column 28, the block 36, the splicing rod 27, the electric push rod 1 26, the scraper 1, the electric push rod 38 and the limit column 37 to rotate together. At this time, the scraper 1 rotates above the spiral chute 8. When the spiral groove of the spiral chute 8 needs to be cleaned, the rotation of the turntable 11 is stopped and the scraper 1 is returned to the position as shown in the figure. Figure 1 The state shown, then start the electric push rod 1 26 to drive the scraper 1 to move down into the spiral groove of the spiral chute 8, and the scraper 1 and the spiral groove of the spiral chute 8 are adapted to fit, then start the electric push rod 38 to drive the limit column 37 to leave the slide column 28, then the slide column 28 is not restricted by the limit column 37, the spring 2 35 is originally in a stretched state, then the slide column 28 will be pulled downward, but it is restricted by the contact between the scraper 1 and the spiral chute 8, and the slide column 28 will not slide downward in the connecting tube 2. At this time, let the turntable 11 rotate clockwise, then the spring 2 35, the slide column 28, the block 36, and the splicing rod 27 , electric push rod 1 26, scraper 1, electric push rod 3 38 and limit column 37 will rotate clockwise together, and under the downward pulling action of spring 2 35 on slide column 28, scraper 1 will move downward in a spiral along the spiral groove surface of spiral chute 8, and slide column 28 will slide downward in connecting tube 2, and block 36 will slide downward in slot 1 33 outside connecting tube 2, and block 36 will pass through slot 2 34 provided on three collars 17 and pass over three collars 17 in sequence until scraper 1 reaches the tail of the spiral groove of spiral chute 8, so that impurities adhered in spiral chute 8 can be completely scraped off to avoid affecting the normal use of spiral chute 8. Conversely, if turntable 11 is turned counterclockwise, scraper 1 will move upward in a spiral along spiral chute 8, and slide column 28 and block 36 will move upward while rotating until slide column 28 is in a position as shown in the figure. Figure 10 The height shown is reached, and the electric push rod 3 38 is then started to drive the limit column 37 to be inserted back into the slide column 28, so that the movement of the slide column 28 can be limited, and finally the electric push rod 1 26 is used to drive the scraper 1 to move up to the original height.

[0053] Example 4, please refer to Figure 1 - Figure 11 The present invention also discloses a process for removing impurities and reducing titanium in high-purity quartz sand, comprising the following steps:

[0054] S1: First, the quartz sand slurry enters along the top of the spiral chute 8 from the existing conveying system, and then flows downward along the spiral groove of the spiral chute 8. Particles with a larger specific gravity (such as metal particle impurities such as titanium) are thrown to the inner edge of the spiral groove, and particles with a smaller specific gravity (such as quartz sand particles) are thrown to the outer edge of the spiral groove;

[0055] S2: Start the motor 9, which drives the turntable 11, the connecting tube 2, the four concave plates 29, the four plastic plates 32 and the four magnetic plates 3 to rotate together. The four magnetic plates 3 are attached to the inner side of the spiral chute 8 and rotate. Under the action of magnetic attraction, particles with a larger specific gravity (such as metal particle impurities such as titanium) tend to passively approach the inner edge of the spiral chute 8, which can speed up the separation efficiency and reduce the number of times the quartz sand slurry circulates in the spiral chute 8.

[0056] S3: By setting the mutual cooperation of the flipping mechanism, the adjusting mechanism and the shrinking and expanding components, the four magnetic plates 3 can be intermittently away from the inner side of the spiral chute 8, and the four magnetic plates 3 will also flip 180 degrees during the process, so that the plastic plates 32 on the four magnetic plates 3 face the inner side of the spiral chute 8, so that the particles with larger specific gravity are no longer attracted, which helps the particles with larger specific gravity to move with the water flow and fall out of the spiral chute 8. When the four magnetic plates 3 continue to be with the inner side of the spiral chute 8, they will continue to attract the particles with larger specific gravity. Through intermittent magnetic attraction, excessive aggregation of particles with larger specific gravity is avoided, which helps the particles with larger specific gravity to leave the area near the four magnetic plates 3 faster in the spiral groove of the spiral chute 8 with the water flow, thereby optimizing the particle discharge process;

[0057] S4: Through the cooperation of the elastic component, the annular frame 10, the triangular block 12 and the triangular block 2 14, the spiral chute 8 can also maintain vertical shaking, further avoiding the aggregation of particles, improving the smoothness of the flow of the quartz sand slurry, and further improving the particle separation effect;

[0058] S5: Through the cooperation between the cleaning mechanism and the fixing part, the spiral groove of the spiral chute 8 can be thoroughly cleaned from top to bottom, and the cleaning method is spiral downward and adapted to the shape of the spiral chute 8 to avoid affecting the normal use of the spiral chute 8.
