Description

Technical Field

[0001] The present invention belongs to the technical field of quartz sand processing, and particularly relates to an acid leaching production device for quartz sand processing and treatment. Background Technique

[0002] Quartz sand is quartz particles processed by crushing quartz stones. It belongs to a hard, wear-resistant, and chemically stable silicate non-metallic mineral. 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, silicon iron smelting, metallurgical fluxes, chemicals, plastics, and filter media.

[0003] In the process of quartz sand purification and selection, in order to improve the quality and output of quartz sand purification, by utilizing the characteristics that quartz sand is insoluble in acid and slightly soluble in potassium hydroxide solution, it has become a necessary processing method to treat quartz sand by acid leaching method. After acid leaching, it is necessary to use sodium hydroxide solution to neutralize the quartz sand.

[0004] In the prior art, the processing and treatment of quartz sand generally involve placing quartz sand in a treatment tank for acid leaching treatment. After the acid leaching treatment is completed, the acid solution in the treatment tank is drained, and then an alkali solution is added to achieve neutralization treatment. After the neutralization treatment is completed, it is washed with water until the quartz sand reaches neutrality. Since quartz sand is in the form of fine particles, its large accumulation in the treatment tank will inevitably affect the neutralization efficiency and effect of the alkali solution. Therefore, we provide an acid leaching production device for quartz sand processing and treatment to solve the above problems. Summary of the Invention

[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, causing the immersion liquid supply structure to move until the alkaline cleaning liquid supply mechanism moves to the position of the original acid immersion liquid supply mechanism. Then, the controller is used to start the stroke control hydraulic cylinder to drive the stroke control seat to move towards the alkaline cleaning liquid supply mechanism until the first through-flow port is horizontally inserted and matched with the second diversion pipe. Subsequently, the solenoid valve on the second diversion pipe is opened. Since the height of the alkaline liquid storage tank is higher than that of the first through-flow port, under the action of the potential energy of the alkaline liquid, the alkaline solution in the alkaline liquid storage tank flows through the first through-flow port and the second through-flow port by gravity and enters the corresponding liquid passage cavity in the annular immersion and material turning bin. After the solenoid valve on the second diversion pipe is opened for a period of time, it is closed by the controller. Then, the annular immersion and material turning bin is controlled to rotate 90° so that the next second through-flow port is aligned with the corresponding first through-flow port. At this time, the two first through-flow ports on the first sealing ring body are still aligned with the two second through-flow ports. Subsequently, the controller opens the solenoid valve on the second diversion pipe again for the same time, and the alkaline solution in the alkaline liquid storage tank flows through the first through-flow port and the second through-flow port by gravity again and enters the corresponding liquid passage cavity in the annular immersion and material turning bin. The same control method is adopted until the annular immersion and material turning bin rotates one week to realize the input of the same amount of alkaline solution in each liquid passage cavity, thus realizing the alkaline solution neutralization treatment of the quartz sand in the entire annular immersion and material turning bin.

[0019] Of course, it is not necessary for any product implementing the present invention to simultaneously achieve all the above-mentioned advantages. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0037] For the first specific embodiment, please refer to Figure 1-13 , the present invention is an acid leaching production device for quartz sand processing, including a washing liquid supply structure 1 and a washing and turning structure 2 arranged on one side thereof; wherein, the washing liquid supply structure 1 includes an acid leaching liquid supply mechanism and an alkali washing liquid supply mechanism; the washing and turning structure 2 includes a stroke control mechanism 3, a sand grain conveying mechanism 4 is installed directly above the stroke control mechanism 3, and a washing and turning mechanism 5 is rotatably installed inside the stroke control mechanism 3, and the horizontal movement of the washing and turning mechanism 5 is controlled by the stroke control mechanism 3.

[0038] The stroke control mechanism 3 includes a rotationally arranged transposition control frame 301, a first through-flow port 303 and a first feed port 304; a first sealed ring body 302 is fixedly arranged on one side of the transposition control frame 301, and the rotation of the first sealed ring body 302 is realized through the transposition control frame 301; the first through-flow port 303 is symmetrically opened on one side of the first sealed ring body 302 and is communicated with the inside of the first sealed ring body 302; the first feed port 304 is opened at the top of the first sealed ring body 302 and is communicated with the inside of the first sealed ring body 302.

[0039] The washing and turning mechanism 5 includes a washing and turning component 6 and a washing and sub-chamber component 7; the washing and turning component 6 is rotatably installed inside the first sealed ring body 302 and they are coaxially arranged. The washing and turning component 6 includes a hollow annular washing and turning bin 601. The annular washing and turning bin 601 is rotatably arranged inside the first sealed ring body 302. A plurality of sub-chamber insertion ports 602 communicated with its inner cavity are opened on the inner wall of the annular washing and turning bin 601. A number of second feed ports 603 are opened on the outer wall of the annular washing and turning bin 601. Each group of sub-chamber insertion ports 602 corresponds to a second feed port 603. A number of second through-flow ports 604 communicated with its inner cavity are opened on one side of the annular washing and turning bin 601. Each group of sub-chamber insertion ports 602 corresponds to a second feed port 603 and they are arranged in a staggered manner.

[0040] The immersion washing cavity-dividing assembly 7 is arranged in a circumferential array inside the annular immersion washing and turning bin 601. The immersion washing cavity-dividing assembly 7 is arranged in one-to-one correspondence with the second feed port 603. The immersion washing cavity-dividing assembly 7 includes a flow-through mesh plate 701 that corresponds to the cavity-dividing insertion port 602 one by one. The flow-through mesh plate 701 is slidably inserted and fitted inside the corresponding cavity-dividing insertion port 602. When controlling the movement of the immersion washing and turning mechanism 5 to achieve the horizontal insertion of the first flow-through port 303 and the acid immersion liquid supply mechanism, the acid immersion treatment of the quartz sand inside it is realized through the rotation of the immersion washing and turning mechanism 5. When controlling the movement of the immersion washing and turning mechanism 5 to achieve the horizontal insertion of the first flow-through port 303 and the alkali washing liquid supply mechanism, the alkali washing treatment of the quartz sand inside it is realized through the rotation of the immersion washing and turning mechanism 5.

[0041] In this embodiment of the present invention, the sand grain conveying mechanism 4 includes a second sealed ring body 401. The outer wall of the first sealed ring body 302 is fitted against the inner wall of the second sealed ring body 401 (in the initial position). A sand grain storage bin 402 penetrating the second sealed ring body 401 is fixedly installed at the top of the second sealed ring body 401. A feeding power shaft 403 is rotatably arranged inside the sand grain storage bin 402. A conveying auger blade 404 is fixedly installed on the circumferential side of the feeding power shaft 403. The output end of a feeding control motor 405 installed at the top of the sand grain storage bin 402 is connected to the feeding power shaft 403; as Figure 1 shown, in the initial state, the outer wall of the first sealed ring body 302 is fitted against the inner wall of the second sealed ring body 401, and the first feed port 304 is just aligned with the sand grain storage bin 402. One of the second feed ports 603 is aligned with the first feed port 304. By controlling the operation of the feeding control motor 405 through the controller, the conveying auger blade 404 rotates inside the sand grain storage bin 402. Under the action of the conveying auger blade 404, a certain amount of quartz sand in the sand grain storage bin 402 is conveyed downward through the first feed port 304 and the second feed port 603 and enters between the corresponding two flow-through mesh plates 701 inside the annular immersion washing and turning bin 601. Subsequently, control the rotation of the annular immersion washing and turning bin 601 to make the next second feed port 603 align with the first feed port 304, and in the same way, convey the same amount of quartz sand downward to between the corresponding two flow-through mesh plates 701. In this way, the feeding operation of the quartz sand between each group of flow-through mesh plates 701 inside the annular immersion washing and turning bin 601 can be realized.

[0042] In this embodiment of the present invention, the stroke control mechanism 3 further includes a stroke control frame 305. A stroke control seat 306 is horizontally slidably arranged inside the stroke control frame 305. A stroke control hydraulic cylinder 307 is installed on one side of the stroke control frame 305. The output end of the stroke control hydraulic cylinder 307 is connected to the stroke control seat 306;

[0043] The output shaft of the position-changing control motor 308 installed inside the stroke control seat 306 is fixedly connected to the position-changing control frame 301. The function of the position-changing control motor 308 is to rotate the position-changing control frame 301 by 180 degrees, so as to realize the conversion of the position-changing control frame 301 between the upper and lower positions. On one side of the first sealing ring body 302, a third sealing ring body 309 coaxial with it is fixedly arranged. The first feed inlet 304 is symmetrically arranged on the third sealing ring body 309 (in the initial state, the first feed inlet 304 just aligns with the sand storage bin 402, one of the second feed inlets 603 aligns with the first feed inlet 304, and each first through-flow port 303 aligns with a second through-flow port 604 respectively. During the process of feeding quartz sand, the angle of each rotation of the annular immersion and turning bin 601 is 90°, ensuring that each rotation of the annular immersion and turning bin 601 can make the first through-flow port 303 align with the second through-flow port 604). Inside the top of the position-changing control frame 301, a turning control motor 310 is installed through a motor seat, and the output shaft of the turning control motor 310 is connected to a turning control gear 311.

[0044] In this embodiment of the present invention, the acid leaching liquid supply mechanism includes an acid liquid storage tank 102 fixedly installed on the bearing frame 101. Two first diversion pipes 103 connected to its interior are symmetrically installed on the circumferential side of the acid liquid storage tank 102, and the first diversion pipes 103 are 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 installed on the bearing frame 101. Two second diversion pipes 105 connected to its interior are symmetrically installed on the circumferential side of the alkali liquid storage tank 104, and the second diversion pipes 105 are arranged close to the bottom of the alkali liquid storage tank 104. A discharge diversion pipe 106 is connected to the circumferential side of the alkali liquid storage tank 104 close to the bottom position, and a branch docking pipe 107 corresponding to the first through-flow port 303 one by one is fixedly installed on the discharge diversion pipe 106. Solenoid valves 108 are installed on the first diversion pipe 103, the second diversion pipe 105 and the discharge diversion pipe 106; the inner cavity of the annular immersion and turning bin 601 is divided into several sand turning cavities and liquid through-flow cavities by a through-flow mesh plate 701. The sand turning cavities are arranged between two through-flow mesh plates 701 on each immersion sub-chamber assembly 7. The second feed inlet 603 is communicated with the corresponding sand turning cavity, and the second through-flow port 604 is communicated with the corresponding liquid through-flow cavity.

[0045] The specific working process of this embodiment is as follows: In the initial state, the outer wall of the first sealed ring body 302 is fitted to the inner wall of the second sealed ring body 401, and 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. The feeding control motor 405 is controlled by the controller to operate, so that the conveying auger blade 404 rotates inside the sand storage bin 402. Under the action of the conveying auger blade 404, a certain amount of quartz sand in the sand storage bin 402 is conveyed downward through the first feed port 304 and the second feed port 603 and enters the corresponding sand turning cavity in the annular washing and turning bin 601. Subsequently, the annular washing 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, and the same amount of quartz sand is conveyed downward to the corresponding sand turning cavity in the same way, so as to realize the feeding operation of the quartz sand in each sand turning cavity in the annular washing and turning bin 601.

[0046] After the annular washing and turning bin 601 rotates one week to complete the feeding of the 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 far from the stroke control hydraulic cylinder 307. At this time, the first sealed ring body 302 is completely separated from the second sealed ring body 401, and the position conversion control frame 301 moves to the left of the sand conveying mechanism 4 (as Figure 3 shown), and the first through-flow port 303 just realizes the horizontal plug-in fit with the first diversion pipe 103 on the acid leaching liquid supply mechanism. Subsequently, the controller opens the solenoid valve 108 on the first diversion pipe 103. Since the height of the acid liquid storage tank 102 is higher than the first through-flow port 303, under the action of the potential energy of the acid liquid, the acidic solution in the acid liquid storage tank 102 flows through the first through-flow port 303 and the second through-flow port 604 and enters the corresponding liquid through-flow cavity in the annular washing and turning bin 601. After the solenoid valve 108 on the first diversion pipe 103 is opened for a period of time, it is closed by the controller. Then, the annular washing and turning bin 601 is controlled to rotate 90° so that the next second through-flow port 604 is aligned with the corresponding first through-flow port 303. At this time, the two first through-flow ports 303 on the first sealed ring body 302 are still aligned with the two second through-flow ports 604. Subsequently, the controller opens the solenoid valve 108 on the first diversion pipe 103 for the same time again, and the acidic solution in the acid liquid storage tank 102 flows through the first through-flow port 303 and the second through-flow port 604 again and enters the corresponding liquid through-flow cavity in the annular washing and turning bin 601. The above-mentioned same control method is adopted until the annular washing and turning bin 601 rotates one week to realize the input of the same amount of acidic solution in each liquid through-flow cavity.

[0047] After the input of the same amount of acidic solution in each liquid passing cavity is completed, continue to control the annular immersion turning bin 601 to rotate. During the rotation of the annular immersion turning bin 601, the quartz sand particles in each sand particle turning cavity keep tumbling, and at the same time, the acidic solution in each liquid passing cavity circulates through the through-flow mesh plate 701 (the sieve holes of the through-flow mesh plate 701 are smaller than the quartz sand particles to ensure that the quartz sand particles do not break away from the sand particle turning cavity) in the inner cavity of the entire annular immersion turning bin 601. In this way, sufficient mixing between the quartz sand particles and the acidic solution can be achieved, thus greatly improving the acid leaching treatment effect and efficiency of the quartz sand particles in the annular immersion turning bin 601.

[0048] After the acid leaching process of the quartz sand particles is completed, the annular immersion turning bin 601 returns to its initial position (i.e., each first through-flow port 303 is aligned with a second through-flow port 604). The stroke control hydraulic cylinder 307 is used to drive the stroke control seat 306 to move a small distance in the direction deviating from the acid leaching liquid supply mechanism (i.e., move in the initial direction), so that the first through-flow port 303 is separated from the first diversion pipe 103 on the acid leaching liquid supply mechanism. Then, control the rotation of the first sealing ring body 302 so that one of the first through-flow ports 303 is at the lowest position of the first sealing ring body 302. During this process, the annular immersion turning bin 601 rotates synchronously with the first sealing ring body 302. Subsequently, the acidic solution in the annular immersion turning bin 601 can flow out through the corresponding second through-flow port 604 and first through-flow port 303 in sequence under the action of gravity for collection. During the drainage process of the acidic solution, intermittently control the rotation of the annular immersion turning bin 601 to ensure that the acidic solution in the annular immersion turning bin 601 is completely drained (the rotation angle of the annular immersion turning bin 601 each time is 90°). After the acidic solution in the annular immersion turning bin 601 is completely drained, control the first sealing ring body 302 to rotate in the reverse direction to complete the reset (i.e., return to Figure 6 the position shown).

[0049] Next, the hydraulic cylinder on one side of the immersion liquid supply structure 1 is started through the controller to move the immersion liquid supply structure 1 until the caustic washing liquid supply mechanism moves to the position of the original acid immersion liquid supply mechanism (that is, each second diversion pipe 105 on the caustic soda storage tank 104 is aligned with the first through-flow port 303). Then, the stroke control hydraulic cylinder 307 is started through the controller to drive the stroke control seat 306 to move towards the caustic washing liquid supply mechanism until the first through-flow port 303 is horizontally inserted and matched with the second diversion pipe 105. Subsequently, the solenoid valve 108 on the second diversion pipe 105 is opened. Since the height of the caustic soda storage tank 104 is higher than that of the first through-flow port 303, under the action of the potential energy of the caustic soda, the alkaline solution in the caustic soda storage tank 104 flows through the first through-flow port 303 and the second through-flow port 604 by gravity and enters the corresponding liquid passage cavity in the annular immersion and turning bin 601. After the solenoid valve 108 on the second diversion pipe 105 is opened for a period of time, it is closed through the controller. Then, the annular immersion and turning bin 601 is controlled to rotate 90° so that the next second through-flow port 604 is aligned with the corresponding first through-flow port 303. At this time, the two first through-flow ports 303 on the first sealing ring body 302 are still aligned with the two second through-flow ports 604. Subsequently, the controller opens the solenoid valve 108 on the second diversion pipe 105 again for the same time, and the alkaline solution in the caustic soda storage tank 104 flows through the first through-flow port 303 and the second through-flow port 604 by gravity again and enters the corresponding liquid passage cavity in the annular immersion and turning bin 601. The same control method is adopted until the annular immersion and turning bin 601 rotates one week to realize the input of the same amount of alkaline solution in each liquid passage cavity, thus realizing the caustic soda 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 immersion and turning bin 601 returns to its initial position (i.e., each first through-flow port 303 is aligned with a second through-flow port 604). The stroke control hydraulic cylinder 307 is driven to move the stroke control seat 306 a small distance in the direction away from the alkali washing liquid supply mechanism (i.e., in the initial direction), so that the first through-flow port 303 is disengaged from the second guide pipe 105 on the alkali washing liquid supply mechanism. Then, the first sealing ring body 302 is controlled to rotate so that one of the first through-flow ports 303 is at the lowest position of the first sealing ring body 302. During this process, the annular immersion and turning bin 601 rotates synchronously with the first sealing ring body 302. Subsequently, the alkaline solution in the annular immersion and turning bin 601 can flow out sequentially through the corresponding second through-flow port 604 and first through-flow port 303 under the action of gravity for collection. During the drainage process of the alkaline solution, 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 drained (the rotation angle of the annular immersion and turning bin 601 is 90° each time). After the alkaline solution in the annular immersion and turning bin 601 is completely drained, the first sealing ring body 302 is continuously controlled by the controller to rotate until the first sealing ring body 302 completes a 180° rotation (at this time, the first sealing ring body 302 changes from the Figure 6 initial position to the position directly below, and each branch docking pipe 107 is aligned with the corresponding first through-flow port 303). Then, the stroke control hydraulic cylinder 307 is continuously controlled by the controller to drive the stroke control seat 306 to move in the direction close to the alkali washing liquid supply mechanism until the first through-flow port 303 is horizontally inserted and matched with the branch docking 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. Subsequently, the through-flow mesh plate 701 is controlled to move radially inward to the inside of the annular immersion and turning bin 601 until each sand turning cavity and liquid through cavity are connected. Then, the solenoid valve 108 on the discharge guide pipe 106 is opened by the controller, and under the action of the potential energy of the alkali solution, the alkaline solution in the alkali solution storage tank 104 flows through the discharge guide pipe 106, the first through-flow port 303, and the second through-flow port 604 into the inner cavity of the annular immersion and turning bin 601 by gravity. The quartz sand particles in the entire inner cavity of the annular immersion and turning bin 601 are flushed out through the rapid flow of the alkaline solution in the annular immersion and turning bin 601 for collection.

[0051] After the quartz sand particles in the entire inner cavity of the annular immersion and turning bin 601 are flushed out for collection, the stroke control hydraulic cylinder 307 is driven to move the stroke control seat 306 a small distance in the direction away from the alkali washing liquid supply mechanism (i.e., in the initial direction), so that the first through-flow port 303 is disengaged from the discharge guide pipe 106 on the alkali washing liquid supply mechanism. Subsequently, the immersion liquid supply structure 1 is controlled to move backward and reset (i.e., return to Figure 1at the shown position), the controller controls the first sealed ring body 302 to rotate reversely until the first sealed ring body 302 completes a 180° rotation and returns to Figure 6 the shown position, and then the stroke control hydraulic cylinder 307 is used to drive the stroke control seat 306 to move away from the acid leaching liquid supply mechanism until reset. After controlling each flow-through net plate 701 to synchronously move radially back to the initial position, the acid leaching and alkali neutralization processing of the next batch of quartz sand particles can be realized again.

[0052] Specific Embodiment 2: On the basis of Specific Embodiment 1, a limiting channel 605 is opened on one side of the annular washing and turning bin 601 away from the second flow-through port 604. An unlocking and pushing part 606 is slidably arranged inside the limiting channel 605. An internal gear ring 607 is rotatably installed on one side of the annular washing and turning bin 601 close to the unlocking and pushing part 606. The internal gear ring 607 is coaxially arranged with the annular washing and turning bin 601. A radial force-bearing plate 608 in close contact with the unlocking and pushing part 606 is fixedly arranged on the outer wall of the internal gear ring 607. A radial mounting plate 609 is fixedly arranged on the surface of the annular washing and turning bin 601. An arc-shaped elastic part 610 is arranged between the radial mounting plate 609 and the radial force-bearing plate 608 (the strong elastic force of the arc-shaped elastic part 610 makes the radial force-bearing plate 608 tightly abut against the unlocking and pushing part 606). During the acid leaching and alkali neutralization process, the radial force-bearing plate 608 is always tightly abutting against the unlocking and pushing part 606 to ensure the stability of the cooperation of the flow-through net plate 701 in the sub-chamber insertion port 602.

[0053] In this embodiment of the present invention, an external gear ring 611 is arranged on one side of the annular washing and turning bin 601 away from the second flow-through port 604. The external gear ring 611 is coaxially arranged with the annular washing and turning bin 601. The external gear ring 611 meshes with the turning control gear 311 outside it. The external gear ring 611 and the annular washing and turning bin 601 are connected by a plurality of fixing rods 612. During the whole quartz sand processing process, the rotation of the annular washing and turning bin 601 is realized by controlling the rotation of the external gear ring 611, that is, the controller controls the turning control motor 310 to operate to drive the turning control gear 311 to rotate, and the rotation of the whole washing and turning mechanism 5 is realized under the meshing action of the turning control gear 311 and the external gear ring 611.

[0054] In this embodiment of the present invention, the immersion washing cavity separation assembly 7 further includes an arc-shaped fixing plate 702 coaxial with the annular immersion turning bin 601. The flow-through mesh plate 701 is symmetrically and fixedly arranged on the outer wall of the arc-shaped fixing plate 702. A transmission gear plate 703 is fixedly arranged on the inner wall of the arc-shaped fixing plate 702. Axial linkage rods 704 corresponding one by one to the transmission gear plate 703 are rotatably arranged on the annular immersion turning bin 601. One end of the axial linkage rod 704 is fixedly installed with a first transmission gear 705 meshing with the transmission gear plate 703, and the other end of the axial linkage rod 704 is fixedly installed with a second transmission gear 706. The internal gear ring 607 meshes with each of the second transmission gears 706 inside it; when the controller controls the rotation of the first sealing ring body 302 until the first sealing ring body 302 completes a 180° rotation (at this time, the first sealing ring body 302 changes from the Figure 6 initial position to the position directly below, and each branch docking pipe 107 is aligned with the corresponding first flow-through port 303), the controller unlocks the telescopic cylinder on one side of the unlocking and pushing part 606 to start horizontal pushing on the unlocking and pushing part 606. During the sliding process of the unlocking and pushing part 606 along the limiting channel 605, the arc-shaped elastic member 610 is compressed until the unlocking and pushing part 606 abuts against the other end of the limiting channel 605. During this process, the radial force-receiving plate 608 is rotated by the horizontal pushing of the unlocking and pushing part 606. Under the action of the radial force-receiving plate 608, the internal gear ring 607 is driven to rotate. The internal gear ring 607 drives each of the second transmission gears 706 to rotate synchronously. The first transmission gear 705 rotating synchronously with the second transmission gear 706 drives the transmission gear plate 703 to move towards the axis of the annular immersion turning bin 601, thereby driving each arc-shaped fixing plate 702 to move towards the axis of the annular immersion turning bin 601 synchronously. When the unlocking and pushing part 606 abuts against the other end of the limiting channel 605, the flow-through mesh plate 701 moving synchronously with the arc-shaped fixing plate 702 completely opens each sand particle turning cavity. At this time, the inner cavity of the entire annular immersion turning bin 601 is in a first-to-last communication state. Subsequently, the potential energy of the flowing alkali solution can be used to wash out the quartz sand in the annular immersion turning bin 601 for collection.
