Description

Technical Field

[0002] Quartz sand is quartz particles processed by crushing quartz stone. It is a hard, wear-resistant, chemically stable silicate non-metallic mineral. The milky white or colorless translucent quartz sand is an important industrial mineral raw material and has been widely used in various industrial fields such as glass, ceramics, fireproof materials, smelting ferrosilicon, metallurgical flux, chemicals, plastics and filter materials.

[0003] In the process of quartz sand purification and selection, in order to improve the quality and yield of quartz sand purification, it is necessary to use the acid leaching method to treat quartz sand, taking advantage of the fact that quartz sand is insoluble in acid but slightly soluble in potassium hydroxide solution. After acid leaching, the quartz sand needs to be neutralized with sodium hydroxide solution.

[0004] In the prior art, quartz sand processing generally involves placing quartz sand in a processing tank for acid leaching, discharging the acid in the processing tank after the acid leaching is completed, and then adding alkali solution to achieve neutralization. After the neutralization is completed, the quartz sand is washed with water until it reaches neutrality. Since quartz sand is in the form of fine particles, a large amount of it accumulated in the processing tank is bound to affect the neutralization efficiency and effect of the alkali solution.

[0016] The present invention has the following beneficial effects: 1. After completing the input of the same amount of acidic solution into each liquid-passing cavity, the present invention continues to control the annular leaching and turning bin to rotate. During the rotation of the annular leaching and turning bin, the quartz sand particles in each sand turning cavity are continuously tumbled. At the same time, the acidic solution in each liquid-passing cavity circulates in the entire inner cavity of the annular leaching and turning bin through the flow mesh plate (the sieve holes of the flow mesh plate are smaller than the quartz sand particles to ensure that the quartz sand particles will not escape from the sand turning cavity). In this way, sufficient mixing between the quartz sand particles and the acidic solution can be achieved, thereby greatly improving the acid leaching treatment effect and acid leaching treatment efficiency of the quartz sand particles in the annular leaching and turning bin.

[0017] 2. In the present invention, when the controller controls the first closed ring body to rotate until the first closed ring body completes 180° rotation, the telescopic cylinder on one side of the unlocking push part of the controller starts to push the unlocking push part horizontally, and the arc-shaped elastic member is compressed during the sliding process of the unlocking push part along the limiting groove until the unlocking push part abuts against the other end of the limiting groove. In this process, the unlocking push part pushes the radial force plate horizontally to rotate, and under the action of the radial force plate, the inner gear ring is driven to rotate, and the inner gear ring drives each second The transmission gear rotates synchronously, and the first transmission gear rotating synchronously with the second transmission gear drives the transmission gear plate to move toward the axis center of the annular immersion and turning bin, and then drives each arc-shaped fixed plate to move synchronously toward the axis center of the annular immersion and turning bin. When the unlocking push portion abuts against the other end of the limiting groove, the flow mesh plate moving synchronously with the arc-shaped fixed plate completely opens each sand turning chamber. At this time, the inner cavity of the entire annular immersion and turning bin is in the first connected state, and then the quartz sand in the annular immersion and turning bin can be flushed out and collected by utilizing the flow potential energy of the alkali solution.

[0018] 3. The present invention starts the hydraulic cylinder on one side of the immersion liquid supply structure through the controller to move the immersion liquid supply structure until the alkali washing liquid supply mechanism moves to the original position of the acid immersion liquid supply mechanism, and continues to start the stroke control hydraulic cylinder through the controller to drive the stroke control seat to move towards the alkali washing liquid supply mechanism until the first flow port and the second guide pipe are horizontally plugged and matched, and then the solenoid valve on the second guide pipe is opened. Since the height of the alkali solution storage tank is higher than the first flow port, the alkaline solution in the alkali solution storage tank flows through the first flow port and the second flow port under the action of the alkali solution potential energy and enters the corresponding liquid cavity in the annular immersion turning bin. The solenoid valve on the second guide pipe After being opened for a period of time, it is closed by the controller, and then the annular immersion and turning bin is controlled to rotate 90° so that the next second flow opening is aligned with the corresponding first flow opening. At this time, the two first flow openings on the first closed ring body are still aligned with the two second flow openings. Then the controller opens the solenoid valve on the second guide pipe again for the same time, and the alkaline solution in the alkali solution storage tank flows through the first flow opening and the second flow opening again into the corresponding liquid cavity in the annular immersion and turning bin. The same control method as above is adopted until the annular immersion and turning bin rotates one circle to realize the input of the same amount of alkaline solution in each liquid cavity, thereby realizing the alkali solution neutralization treatment of the quartz sand in the entire annular immersion and turning bin.

[0019] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] The output shaft of the transposition control motor 308 installed inside the stroke control seat 306 is fixedly connected to the transposition control frame 301. The function of the transposition control motor 308 is to realize the rotation of the transposition control frame 301 by 180 degrees, so that the transposition control frame 301 can be switched between the upper and lower positions. A third closed ring body 309 coaxial with the first closed ring body 302 is fixedly provided on one side of the first closed ring body 302. The first feed port 304 is symmetrically opened on the third closed ring body 309 (in the initial state, the first feed port 304 is just aligned with the sand storage bin 402, One of the second feed ports 603 is aligned with the first feed port 304, and each first flow port 303 is aligned with a second flow port 604 respectively. During the quartz sand loading process, the annular immersion and turning bin 601 rotates by 90° each time, ensuring that the first flow port 303 is aligned with the second flow port 604 each time the annular immersion and turning bin 601 rotates. A turning control motor 310 is installed on the top of the transposition control frame 301 through a motor seat, and a turning control gear 311 is connected to the output shaft of the turning control motor 310.

[0044] In this embodiment of the present invention, the acid leaching liquid supply mechanism includes an acid liquid storage tank 102 fixedly mounted on a supporting frame 101, and two first guide pipes 103 connected to the interior of the acid liquid storage tank 102 are symmetrically mounted on the side surface thereof, and the first guide pipe 103 is arranged close to the bottom of the acid liquid storage tank 102; the alkali washing liquid supply mechanism includes an alkali liquid storage tank 104 fixedly mounted on the supporting frame 101, and two second guide pipes 105 connected to the interior of the alkali liquid storage tank 104 are symmetrically mounted on the side surface thereof, and the second guide pipe 105 is arranged close to the bottom of the alkali liquid storage tank 104, and the alkali liquid storage tank 104 is arranged close to the side surface thereof. A discharge guide pipe 106 is provided at the bottom position, and a branch connecting pipe 107 corresponding to the first flow opening 303 is fixedly installed on the discharge guide pipe 106, and a solenoid valve 108 is installed on the first guide pipe 103, the second guide pipe 105 and the discharge guide pipe 106; the inner cavity of the annular immersion and turning bin 601 is divided into a plurality of sand turning chambers and liquid passage chambers by a flow mesh plate 701, and the sand turning chamber is arranged between the two flow mesh plates 701 on each immersion chamber assembly 7, the second feed port 603 is connected to the corresponding sand turning chamber, and the second flow opening 604 is connected to the corresponding liquid passage chamber.

[0045] The specific working process of this embodiment is as follows: in the initial state, the outer wall of the first closed ring body 302 is fitted on the inner wall of the second closed ring body 401, and the first feed port 304 is just aligned with the sand storage bin 402, and one of the second feed ports 603 is aligned with the first feed port 304. The controller controls the feeding control motor 405 to operate, so that the conveying auger piece 404 rotates inside the sand storage bin 402. Under the action of the conveying auger piece 404, a certain amount of quartz sand in the sand storage bin 402 is transported downward through the first feed port 304 and the second feed port 603 into the corresponding sand turning cavity in the annular immersion and turning bin 601. Then, the annular immersion and turning bin 601 is controlled to rotate 90° so that the next second feed port 603 is aligned with the first feed port 304. In the same way, the same amount of quartz sand is transported downward to the corresponding sand turning cavity. In this way, the loading operation of quartz sand in each sand turning cavity in the annular immersion and turning bin 601 can be realized.

[0046] After the annular leaching and turning bin 601 rotates one circle to realize the loading of quartz sand in each sand turning cavity in its inner cavity, the controller starts the stroke control hydraulic cylinder 307 to drive the stroke control seat 306 to approach the acid leaching liquid supply mechanism until the stroke control seat 306 abuts against the inner wall of the stroke control frame 305 away from the stroke control hydraulic cylinder 307. At this time, the first closed ring body 302 is completely separated from the second closed ring body 401, and the transposition control frame 301 moves to the left side of the sand conveying mechanism 4 (such as Figure 3 As shown in the figure, the first flow opening 303 just realizes the horizontal plug-in cooperation with the first guide tube 103 on the acid leaching liquid supply mechanism, and then the controller opens the solenoid valve 108 on the first guide tube 103. Since the height of the acid storage tank 102 is higher than the first flow opening 303, the acid solution in the acid storage tank 102 flows through the first flow opening 303 and the second flow opening 604 under the action of the acid potential energy and enters the corresponding liquid cavity in the annular leaching and turning bin 601. The solenoid valve 108 on the first guide tube 103 is opened for a period of time and then closed by the controller, and then the annular leaching and turning bin 601 is controlled to rotate. Move 90° so that the next second flow opening 604 is aligned with the corresponding first flow opening 303. At this time, the two first flow openings 303 on the first closed ring body 302 are still aligned with the two second flow openings 604. Then the controller opens the solenoid valve 108 on the first guide tube 103 again for the same time, and the acid solution in the acid storage tank 102 flows through the first flow opening 303 and the second flow opening 604 again into the corresponding liquid cavity in the annular immersion and turning bin 601. The same control method as above is adopted until the annular immersion and turning bin 601 rotates one circle to realize the input of the same amount of acid solution in each liquid cavity.

[0047] After completing the input of the same amount of acidic solution into each liquid-passing cavity, continue to control the annular leaching and turning bin 601 to rotate. During the rotation of the annular leaching and turning bin 601, the quartz sand particles in each sand turning cavity are continuously tumbling. At the same time, the acidic solution in each liquid-passing cavity circulates in the entire inner cavity of the annular leaching and turning bin 601 and passes through the flow mesh plate 701 (the sieve holes of the flow mesh plate 701 are smaller than the quartz sand particles to ensure that the quartz sand particles will not escape from the sand turning cavity). In this way, sufficient mixing between the quartz sand particles and the acidic solution can be achieved, thereby greatly improving the acid leaching treatment effect and efficiency of the quartz sand particles in the annular leaching and turning bin 601.

[0048] After the acid leaching of the quartz sand particles is completed, the annular leaching and turning bin 601 returns to the initial position (i.e., each first flow opening 303 is aligned with a second flow opening 604), and the stroke control hydraulic cylinder 307 drives the stroke control seat 306 to move a small distance away from the acid leaching liquid supply mechanism (i.e., move to the initial direction), so that the first flow opening 303 is separated from the first guide pipe 103 on the acid leaching liquid supply mechanism, and then the first closed ring body 302 is controlled to rotate so that one of the first flow openings 303 is at the lowest position of the first closed ring body 302. In this process, the annular leaching and turning bin 601 is 01 rotates synchronously with the first closed loop body 302, and then the acidic solution in the annular immersion and turning bin 601 can be discharged through the corresponding second flow opening 604 and the first flow opening 303 in sequence under the action of gravity to achieve collection. During the acidic solution discharge process, the annular immersion and turning bin 601 is intermittently controlled to rotate to ensure that the acidic solution in the annular immersion and turning bin 601 is completely discharged (the annular immersion and turning bin 601 rotates 90° each time). After the acidic solution in the annular immersion and turning bin 601 is completely discharged, the first closed loop body 302 is controlled to rotate in the opposite direction to complete the reset (i.e., return to the Figure 6 shown in the position).

[0049] Then, the hydraulic cylinder on one side of the leaching liquid supply structure 1 is started by the controller to move the leaching liquid supply structure 1 until the alkali washing liquid supply mechanism moves to the original position of the acid leaching liquid supply mechanism (that is, each second guide tube 105 on the alkali liquid storage tank 104 is aligned with the first flow port 303), and the stroke control hydraulic cylinder 307 is continued to be started by the controller to drive the stroke control seat 306 to move toward the alkali washing liquid supply mechanism until the first flow port 303 and the second guide tube 105 are horizontally plugged and matched, and then the solenoid valve 108 on the second guide tube 105 is opened. Since the height of the alkali liquid storage tank 104 is higher than the first flow port 303, the alkaline solution in the alkali liquid storage tank 104 flows by gravity through the first flow port 303 and the second flow port 604 under the action of the alkali liquid potential energy and enters the corresponding liquid cavity in the annular leaching material turning bin 601. The solenoid valve 108 on the second flow guide pipe 105 is opened for a period of time and then closed by the controller. Then the annular immersion and turning bin 601 is controlled to rotate 90° so that the next second flow opening 604 is aligned with the corresponding first flow opening 303. At this time, the two first flow openings 303 on the first closed ring body 302 are still aligned with the two second flow openings 604. Then the controller opens the solenoid valve 108 on the second flow guide pipe 105 again for the same time, and the alkaline solution in the alkali solution storage tank 104 flows through the first flow opening 303 and the second flow opening 604 again into the corresponding liquid cavity in the annular immersion and turning bin 601. The same control method as above is adopted until the annular immersion and turning bin 601 rotates one circle to realize the input of the same amount of alkaline solution in each liquid cavity, thereby realizing the alkali solution neutralization treatment of the quartz sand in the entire annular immersion and turning bin 601.

[0050] After the alkali solution neutralization treatment of the quartz sand particles is completed, the annular leaching and turning bin 601 returns to the initial position (that is, each first flow opening 303 is aligned with a second flow opening 604), and the stroke control hydraulic cylinder 307 drives the stroke control seat 306 to move a small distance away from the alkali washing liquid supply mechanism (that is, move in the initial direction), so that the first flow opening 303 is separated from the second guide pipe 105 on the alkali washing liquid supply mechanism, and then the first closed ring body 302 is controlled to rotate so that one of the first flow openings 303 is at the lowest position of the first closed ring body 302. In this process, the annular leaching and turning bin 601 is moved with the first closed ring body 302. The alkaline solution in the annular immersion and turning bin 601 is rotated step by step, and then the alkaline solution in the annular immersion and turning bin 601 can be discharged through the corresponding second flow opening 604 and the first flow opening 303 in sequence under the action of gravity to be collected. During the alkaline solution discharge process, the annular immersion and turning bin 601 is intermittently controlled to rotate to ensure that the alkaline solution in the annular immersion and turning bin 601 is completely discharged (the annular immersion and turning bin 601 rotates 90° each time). After the alkaline solution in the annular immersion and turning bin 601 is completely discharged, the first closed ring body 302 is continued to be controlled to rotate by the controller until the first closed ring body 302 completes a 180° rotation (at this time, the first closed ring body 302 is Figure 6 The initial position of the tributary pipe 107 is changed to the position directly below, and each branch pipe 107 is aligned with the corresponding first flow port 303. Then, the stroke control hydraulic cylinder 307 is controlled by the controller to drive the stroke control seat 306 to move toward the direction close to the alkali washing liquid supply mechanism until the first flow port 303 is horizontally plugged into the tributary pipe 107. At this time, the first feed port 304 is vertically downward, and the first feed port 304 is aligned with a second feed port 603. Then, the flow mesh plate 701 is controlled to synchronously move to the annular immersion and turning bin 601. Move radially inward until each sand turning chamber and liquid flow chamber are connected, and then open the solenoid valve 108 on the discharge guide pipe 106 through the controller. Under the action of the potential energy of the alkali solution, the alkaline solution in the alkali solution storage tank 104 flows by gravity through the discharge guide pipe 106, the first flow port 303 and the second flow port 604 into the inner cavity of the annular immersion turning bin 601. The quartz sand particles in the inner cavity of the entire annular immersion turning bin 601 are flushed out and collected through the rapid flow of the alkaline solution in the annular immersion turning bin 601.

[0051] After the quartz sand particles in the inner cavity of the entire annular leaching and turning bin 601 are flushed out and collected, the stroke control hydraulic cylinder 307 drives the stroke control seat 306 to move a small distance away from the alkali washing liquid supply mechanism (i.e., move in the initial direction), so that the first flow port 303 is separated from the discharge guide pipe 106 on the alkali washing liquid supply mechanism, and then the leaching liquid supply structure 1 is controlled to move in the reverse direction and reset (i.e., return to the original position). Figure 1The controller controls the first closed ring body 302 to rotate in the opposite direction until the first closed ring body 302 completes a 180° rotation and returns to the Figure 6 At the position shown, the stroke control hydraulic cylinder 307 drives the stroke control seat 306 to move away from the acid leaching liquid supply mechanism until it is reset. After controlling each flow screen plate 701 to move radially back to the initial position synchronously, the acid leaching and alkali neutralization processing of the next batch of quartz sand particles can be realized again.

During the acid leaching and alkali neutralization process, the radial force plate 608 is always tightly pressed against the unlocking push portion 606 to ensure the stability of the flow mesh plate 701 in the dividing chamber plug interface 602.

[0053] In this embodiment of the present invention, an outer gear ring 611 is provided on the side of the annular immersion and turning bin 601 away from the second flow port 604. The outer gear ring 611 is coaxially arranged with the annular immersion and turning bin 601, and the outer gear ring 611 is meshed with the turning control gear 311 on its outer side. The outer gear ring 611 and the annular immersion and turning bin 601 are connected by a plurality of fixed rods 612. During the entire quartz sand processing process, the rotation of the annular immersion and turning bin 601 is achieved by controlling the rotation of the outer gear ring 611, that is, the controller controls the turning control motor 310 to drive the turning control gear 311 to rotate, and the rotation of the entire immersion and turning mechanism 5 is achieved under the meshing action of the turning control gear 311 and the outer gear ring 611.

An axial linkage rod 704 corresponding to the transmission tooth plate 703 is rotatably arranged on the annular immersion turning bin 601, and a first transmission gear 705 meshing with the transmission tooth plate 703 is fixedly installed at one end of the axial linkage rod 704, and a second transmission gear 706 is fixedly installed at the other end of the axial linkage rod 704, and the inner gear ring 607 and each second transmission gear 706 on its inner side are meshed with each other; the first closed ring body 302 is controlled to rotate by the controller until the first closed ring body 302 completes a 180° rotation (at this time, the first closed ring body 302 is rotated by Figure 6 When the initial position of the unlocking push part 606 is changed to the position directly below, and each tributary connecting pipe 107 is aligned with the corresponding first flow opening 303, the telescopic cylinder on one side of the unlocking push part 606 of the controller is started to push the unlocking push part 606 horizontally, and the arc-shaped elastic member 610 is compressed during the sliding process of the unlocking push part 606 along the limiting groove 605 until the unlocking push part 606 abuts against the other end of the limiting groove 605. In this process, the radial force plate 608 is horizontally pushed by the unlocking push part 606 to rotate, and the inner gear ring 607 is driven to rotate under the action of the radial force plate 608, thereby driving each second transmission unit 607 to rotate. The movable gear 706 rotates synchronously, and the first transmission gear 705 rotating synchronously with the second transmission gear 706 drives the transmission gear plate 703 to move toward the axis center of the annular immersion and turning bin 601, and then drives each arc-shaped fixed plate 702 to move synchronously toward the axis center of the annular immersion and turning bin 601. When the unlocking push portion 606 abuts against the other end of the limiting groove 605, the flow mesh plate 701 moving synchronously with the arc-shaped fixed plate 702 completely opens each sand turning chamber. At this time, the inner cavity of the entire annular immersion and turning bin 601 is in the first connected state, and then the quartz sand in the annular immersion and turning bin 601 can be flushed out and collected by utilizing the flow potential energy of the alkali solution.
