Description

Technical Field

[0001] This invention relates to the field of quartz sand purification technology, and in particular to a continuous quartz sand purification and treatment device. Background Technology

[0002] The continuous quartz sand purification and treatment device is a specialized equipment for the continuous purification and particle size classification of quartz sand raw materials, including crushed natural quartz ore, vein quartz coarse sand, ordinary industrial quartz sand, and high-purity quartz sand raw materials for photovoltaic and semiconductor applications.

[0003] Chinese utility model CN217149004U discloses a continuous cold explosion purification device for quartz sand. It uses a lifting drive device to drive a connecting rod to intermittently lift a floating plate, causing a valve column vertically fixed on the floating plate to synchronously insert and remove the sieve holes on the bottom plate of the cold explosion water tank. While completing the cold explosion purification of quartz sand, it also achieves the screening and continuous discharge of quartz sand of qualified particle size. However, the sieve holes on the bottom plate of the cold explosion water tank are a fixed-diameter integrated structure, making it impossible to adjust the screening aperture according to the particle size requirements of different quartz sand products. For quartz sand products with different mesh size requirements, the bottom plate of the water tank needs to be replaced with one of corresponding aperture sizes, resulting in poor adaptability in the purification and production of multi-specification quartz sand.

[0034] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0035] The cold explosion purification structure includes a cold explosion chamber for holding cooling water and heated quartz sand to be purified. The structure also has a supplementary opening connected to the cold explosion chamber. Multiple sieve holes are located at the bottom of the structure and are connected to the cold explosion chamber. A storage structure is situated at the bottom of the structure and includes a storage cavity connected to the sieve holes. This storage cavity stores qualified quartz sand after sieving through the sieve holes and cooling water, thereby achieving the desired purification process. This integrated continuous operation, encompassing cold-blast purification, online screening, and finished product collection, utilizes the space provided by the cold-blast chamber to ensure the rapid cooling and blasting effect of heated quartz sand, laying a qualified raw material foundation for subsequent multi-specification screening and purification. The top supplementary opening allows for uninterrupted material and cooling water supply during production, adapting to continuous purification needs without interrupting production.

The moving screen plates slide synchronously along the radial direction of the corresponding screen holes, thus achieving stepless online adjustment and independent on / off control of the sieve aperture of a single screen hole. This eliminates the need for machine shutdown, disassembly, or replacement of the screen, or dismantling of the main unit. The adjustable flow channel aperture can be adjusted simply by driving the synchronous radial sliding of the moving screen plates, matching the sieve purification needs of various specifications of quartz sand, from fine powder to coarse particles. The sealing surface formed by the circumferential sliding contact of the moving screen plates enables the closing and stopping of a single screen hole. Corresponding screen holes can be flexibly activated and deactivated according to multi-specification production needs. This allows for simultaneous purification of a large batch of single-specification quartz sand across all channels, as well as simultaneous sieve purification of a small batch of multi-specification quartz sand across different channels. This solves the problem of traditional fixed-aperture screens only being suitable for single-specification quartz sand purification and having low production changeover efficiency, improving the adaptability of the device in multi-specification quartz sand purification production.

The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0049] See Figures 4-6 The specific implementation of a preferred embodiment of the present invention is as follows: A continuous quartz sand purification and treatment device includes: a cold explosion purification structure 1, a storage structure 2, and multiple pore size adjustment components 3.

[0050] The cold explosion purification structure 1 is provided with a cold explosion chamber 11, which is used to hold cooling water and heated quartz sand to be purified; the cold explosion purification structure 1 is provided with a supplementary opening 12, which is connected to the cold explosion chamber 11; the bottom of the cold explosion purification structure 1 is provided with a plurality of sieve holes 13, which are all connected to the cold explosion chamber 11.

[0051] The storage structure 2 is located at the bottom of the cold explosion purification structure 1. The storage structure 2 is provided with a storage cavity 21, which is connected to the sieve hole 13. The storage cavity 21 is used to store qualified particle size quartz sand and cooling water after being screened by the sieve hole 13.

[0052] Each aperture adjustment component 3 is respectively disposed at a corresponding sieve hole 13; the aperture adjustment component 3 has multiple movable sieve plates 31 and a driving device 32; the multiple movable sieve plates 31 are arranged at intervals along the circumference of the corresponding sieve hole 13, and each can slide back and forth along the radial direction of the corresponding sieve hole 13; one circumferential side of each movable sieve plate 31 slides and fits against the corresponding circumferential side of the adjacent movable sieve plate 31; when the two circumferential sides of the adjacent movable sieve plates 31 are completely fitted, the multiple movable sieve plates 31 together form a continuous sealing surface 311, the sealing surface 311 is used to seal the corresponding sieve hole 13; when the adjacent movable sieve plates 31 slide away from each other in the radial direction, the fitted two circumferential sides are misaligned, the sealing surface 311 is released, and the multiple movable sieve plates 31 together form an adjustable flow channel 312, the adjustable flow channel 312 is connected to the corresponding sieve hole 13;

[0053] The driving device 32 is connected to the plurality of movable screen plates 31 in a transmission manner, and the driving device 32 is used to drive the plurality of movable screen plates 31 to slide synchronously along the radial direction of the corresponding screen holes 13.

[0054] In use, first operate the drive device 32 of each aperture adjustment component 3 to drive the movable screen plate 31 at the corresponding screen hole 13 to slide synchronously along the radial direction of the screen hole 13 until the circumferential sides of the adjacent movable screen plates 31 are completely attached to form a continuous sealing surface 311, thus completing the closing operation of all screen holes 13; after the closing is completed, cool water is injected into the cold explosion chamber 11 through the supplementary opening 12 at the top of the cold explosion purification structure 1, and then heated quartz sand to be purified is put into the cold explosion chamber 11 through the supplementary opening 12, so that the quartz sand to be purified completes the cold explosion treatment in the cooling water in the cold explosion chamber 11; after the cold explosion treatment is completed, the opening sieving operation is performed, and the drive device 32 of the aperture adjustment component 3 at the corresponding screen hole 13 is operated to drive the movable screen plate 31 at the corresponding screen hole 13 to slide synchronously in opposite directions along the radial direction of the screen hole 13, so that the attached circumferential sides are misaligned, the sealing surface 311 is released, and multiple movable screen plates 31 together form an adjustable flow channel 312;

[0055] When producing single-specification quartz sand, the drive devices 32 corresponding to all sieve holes 13 are operated synchronously to ensure that the diameter of the adjustable flow channel 312 formed by the movable sieve plates 31 at all sieve holes 13 remains consistent. When producing multiple specifications of quartz sand simultaneously, such as simultaneously producing 40-70 mesh and 70-120 mesh finished products, the drive devices 32 corresponding to the sieve holes 13 are operated separately to make the diameter of the adjustable flow channel 312 of some sieve holes 13 match the sieve particle size of 40-70 mesh quartz sand, and the diameter of the adjustable flow channel 312 of other sieve holes 13 match the sieve particle size of 70-120 mesh quartz sand.

[0056] When it is necessary to switch the production specifications of quartz sand during the screening process, the drive device 32 at the corresponding screen hole 13 is directly operated to drive the movable screen plate 31 to slide synchronously along the radial direction of the screen hole 13, adjust the misalignment of adjacent movable screen plates 31, and change the aperture of the adjustable flow channel 312; or drive the movable screen plate 31 to slide radially towards each other until the two sides of the circumference are completely in contact, forming a sealing surface 311 to close the corresponding screen hole 13; the qualified particle size quartz sand and cooling water after screening by the adjustable flow channel 312 fall into the storage structure 2 at the bottom of the cold explosion purification structure 1 and are received and stored by the storage cavity 21; after the production is completed, the drive device 32 of all aperture adjustment components 3 is operated to drive the movable screen plate 31 at the corresponding screen hole 13 to slide radially towards each other until the two sides of the circumference are completely in contact, forming a sealing surface 311 to seal all screen holes 13, and then the remaining material in the cold explosion cavity 11 is cleaned through the supplementary opening 12, and the purified quartz sand product is collected through the storage cavity 21 of the storage structure 2.

[0057] Obviously, the cold explosion purification structure 1 is provided with a cold explosion chamber 11, which is used to hold cooling water and heated quartz sand to be purified; the cold explosion purification structure 1 has a supplementary opening 12, which is connected to the cold explosion chamber 11; the bottom of the cold explosion purification structure 1 has multiple sieve holes 13, all of which are connected to the cold explosion chamber 11; the storage structure 2 is located at the bottom of the cold explosion purification structure 1, and the storage structure 2 has a storage cavity 21, which is connected to the sieve holes 13; the storage cavity 21 is used to store qualified particle size quartz sand after being sieved by the sieve holes 13 and cooling water; thereby realizing the cold explosion of quartz sand. The integrated continuous operation of purification, online screening, and finished product collection ensures the rapid cooling and crushing effect of heated quartz sand through the containment space provided by the cold explosion chamber 11, laying a qualified raw material foundation for subsequent multi-specification screening and purification. The top supplementary opening 12 can realize uninterrupted material and cooling water supply during the production process, adapting to the continuous purification requirements without stopping production. The arrangement of multiple screen holes 13 at the bottom, combined with the support of the storage chamber 21, can realize multi-channel synchronous screening and unified collection of qualified materials and cooling water, providing a stable structural carrier for subsequent independent aperture adjustment of screen holes 13 and multi-specification synchronous screening. Each aperture adjustment component 3 is respectively set at a corresponding screen hole 13. The aperture adjustment assembly 3 has multiple movable screen plates 31 and a driving device 32. The multiple movable screen plates 31 are arranged at intervals along the circumference of the corresponding screen holes 13, and each can slide back and forth radially along the corresponding screen hole 13. One circumferential side of each movable screen plate 31 slides against the corresponding circumferential side of the adjacent movable screen plate 31. When the circumferential sides of adjacent movable screen plates 31 are fully against each other, the multiple movable screen plates 31 together form a continuous sealing surface 311, which is used to seal the corresponding screen hole 13. When adjacent movable screen plates 31 slide away radially from each other, the against-grip circumferential sides are misaligned, the sealing surface 311 is released, and the multiple movable screen plates 31 slide back and forth. The sieve plates 31 together form an adjustable flow channel 312, which is connected to the corresponding sieve hole 13. The driving device 32 is connected to the multiple movable sieve plates 31 and is used to drive the multiple movable sieve plates 31 to slide synchronously along the radial direction of the corresponding sieve hole 13. This realizes the stepless online adjustment and independent on / off control of the sieve aperture of a single sieve hole 13. There is no need to stop the machine to disassemble and replace the sieve or disassemble the main body of the device. The aperture of the adjustable flow channel 312 can be adjusted by driving the movable sieve plates 31 to slide synchronously in the radial direction, so as to match the sieve purification needs of quartz sand of different specifications from fine powder to coarse particles.The sealing surface 311 formed by the circumferential sliding contact of the movable screen plate 31 enables the closure and shutdown of a single screen hole 13. This allows for flexible activation and deactivation of corresponding screen holes 13 according to the production needs of multiple specifications. It enables simultaneous purification of a large batch of single-specification quartz sand across all channels, as well as simultaneous screening and purification of small batches of multiple-specification quartz sand across different channels. This solves the problem of traditional fixed-aperture screens only being suitable for single-specification quartz sand purification and having low production changeover efficiency, thus improving the adaptability of the device in the purification and production of multi-specification quartz sand.

[0058] See Figure 1 , Figures 4-6 In this embodiment, in order to more effectively improve the adaptability in the purification and production of multi-specification quartz sand, preferably, the cold explosion purification structure 1 is provided with a base plate 14, which is detachably installed at the bottom of the cold explosion chamber 11.

[0059] The base plate 14 has mounting through holes 141 corresponding to each of the sieve holes 13. Each mounting through hole 141 extends along the axial direction of the corresponding sieve hole 13 and is connected to the corresponding sieve hole 13.

[0060] The bottom of the base plate 14 and the bottom of the cold explosion chamber 11 together form an installation space 15. Each of the aperture adjustment components 3 is placed in the installation space 15 and installed in the corresponding installation through hole 141.

[0061] The continuous quartz sand purification device also includes a control terminal 4, which is installed on the cold explosion purification structure 1 and is electrically connected to the drive device 32 of each of the aperture adjustment components 3.

[0062] The detachable base plate 14 serves as the mounting base for the aperture adjustment component 3, enabling modular pre-assembly and overall disassembly of the aperture adjustment component 3. Inspection, replacement, and maintenance of the aperture adjustment component 3 can be completed without disassembling the main body of the cold explosion purification structure 1. The sealed installation space 15 formed by the base plate 14 and the bottom of the cold explosion chamber 11 isolates the aperture adjustment component 3 from the water and sand media within the cold explosion chamber 11 and storage chamber 21, preventing quartz sand particles and cooling water from entering the drive clearance and causing jamming and wear. This ensures the stability of the aperture adjustment action and adapts to the continuous production requirements of multi-specification quartz sand. The control terminal 4, electrically connected to the drive device 32 of each aperture adjustment component 3, enables centralized control of the aperture of all sieve holes 13, allowing for convenient switching of aperture parameters corresponding to different specifications of quartz sand production, further improving the adaptability and efficiency of multi-specification quartz sand purification production.

[0063] The bottom plate 14 and the bottom of the cold explosion chamber 11 are detachably fixedly connected by multiple sets of threaded fasteners evenly distributed along the circumference.

[0064] See Figures 5-8 Furthermore, the aperture adjustment assembly 3 is provided with a guide base 33 and a rotary adjustment seat 34; the guide base 33 is installed on the base plate 14 at the location corresponding to the mounting through hole 141; the guide base 33 has a first through hole 331, which penetrates the guide base 33 along the axial direction corresponding to the mounting through hole 141; the rotary adjustment seat 34 is rotatably mounted on the guide base 33 around the axis of the first through hole 331; the rotary adjustment seat 34 has a second through hole 341, which penetrates the rotary adjustment seat 34 along the axial direction corresponding to the mounting through hole 141; the driving device 32 is connected to the rotary adjustment seat 34 in a transmission manner, and the driving device 32 is used to drive the rotary adjustment seat 34 to rotate around the axis of the first through hole 331;

[0065] Each of the movable sieve plates 31 is arranged between the guide base 33 and the rotary adjustment base 34. The two opposite ends of the movable sieve plates 31 are an adjustment execution end 313 and a movable end 314, respectively. The adjustment execution end 313 extends into the corresponding sieve hole 13 and together form the adjustable flow channel 312 or are mutually attached to form the sealing surface 311. The movable end 314 is provided with a force-bearing part 315. The mounting through hole 141, the first through hole 331, the adjustable flow channel 312, the second through hole 341, and the corresponding sieve hole 13 are connected in sequence.

[0066] The rotary adjustment seat 34 has multiple radial transmission grooves 342, which are equally spaced around the periphery of the second through hole 341 in the circumferential direction. The movable end 314 of each movable sieve plate 31 is slidably embedded in the corresponding radial transmission groove 342. The adjustment execution end 313 of the movable sieve plate 31 slides radially along the corresponding sieve hole 13 as the movable end 314 slides along the length direction of the radial transmission groove 342.

[0067] The guide base 33 is also provided with a plurality of radial guide grooves 332, which are arranged at intervals along the circumference of the first through hole 331 and extend from the axis of the first through hole 331 to the circumferentially outer side of the guide base 33. The force-bearing part 315 of each movable screen plate 31 is slidably embedded in the corresponding radial guide groove 332. The radial guide groove 332 is used to convert the rotation action of the rotary adjustment seat 34 into the synchronous sliding action of the adjustment execution end 313 of each movable screen plate 31 along the radial direction of the corresponding screen hole 13.

[0068] The coaxial assembly structure of the guide base 33 and the rotary adjustment seat 34 provides a stable assembly and transmission carrier for the radial sliding of the movable screen plate 31, converting the rotational power of the drive device 32 into the synchronous radial sliding action of each movable screen plate 31, ensuring the consistency of the sliding amplitude of each movable screen plate 31; the double groove cooperation between the radial transmission groove 342 of the rotary adjustment seat 34 and the radial guide groove 332 of the guide base 33 limits the sliding process of the movable screen plate 31 without radial wobble or circumferential misalignment, ensuring both the sealing reliability in the blocking state and the consistency of the aperture in the screening state, adapting to the accuracy requirements of synchronous screening of multi-specification quartz sand.

[0069] The specific transmission process is as follows: When the drive device 32 outputs rotational power and drives the rotary adjustment seat 34 to rotate circumferentially around the axis of the first through hole 331, the radial transmission grooves 342 on the rotary adjustment seat 34 rotate circumferentially synchronously with the rotary adjustment seat 34. The inner wall of the radial transmission groove 342 applies a circumferential tangential force to the movable end 314 of the movable screen plate 31 embedded in the groove. At the same time, because the force-bearing part 315 of the movable screen plate 31 is embedded in the radial guide groove 332 fixedly provided on the guide base 33, the radial guide groove 332 forms a circumferential limit on the movable screen plate 31, restricting the movable screen plate 31 from rotating circumferentially with the rotary adjustment seat 34, and only allowing the movable screen plate 31 to slide linearly along the extension direction of the radial guide groove 332. Under this double limiting cooperation, the radial transmission groove The circumferential tangential force applied by 342 is decomposed into a radial driving force extending along the radial guide groove 332, which drives all movable screen plates 31 to slide synchronously along the radial direction of the corresponding screen hole 13. When the rotary adjustment seat 34 rotates in the forward direction, it drives all movable screen plates 31 to slide synchronously towards each other in the radial direction until the adjustment execution ends 313 of each movable screen plate 31 are completely attached to both sides in the circumferential direction, forming a sealing surface 311. When the rotary adjustment seat 34 rotates in the reverse direction, it drives all movable screen plates 31 to slide synchronously away from each other in the radial direction. The contact sides of adjacent movable screen plates 31 are misaligned, forming an adjustable flow channel 312. By controlling the rotation angle of the rotary adjustment seat 34, the radial sliding amplitude of the movable screen plates 31 can be controlled, realizing stepless adjustment of the aperture of the adjustable flow channel 312.

[0070] Furthermore, the top of the guide base 33 is provided with a plurality of limiting insertion parts 333, which are arranged at intervals along the circumference of the first through hole 331; the bottom plate 14 is provided with a plurality of insertion slots 142 on the side facing the mounting space 15, which surround the periphery of the corresponding mounting through hole 141; each limiting insertion part 333 is inserted into the corresponding insertion slot 142 so that the first through hole 331 and the mounting through hole 141 are coaxially arranged.

[0071] By engaging the limiting insertion part 333 of the guide base 33 with the insertion slot 142 of the base plate 14, the guide base 33 and the base plate 14 are quickly positioned and assembled. This ensures that the first through hole 331 of the guide base 33 is coaxially arranged with the mounting through hole 141 and the screen hole 13 of the base plate 14, preventing circumferential deflection and radial offset of the guide base 33. This also ensures the alignment of the radial sliding trajectory of the movable screen plate 31 with the axis of the screen hole 13, further improving the accuracy and stability of the aperture adjustment. The circumferential rotation of the guide base 33 is restricted by multiple sets of circumferentially spaced insertion structures, preventing the guide base 33 from being synchronously deflected during the rotation of the rotating adjustment seat 34, thus ensuring the stable operation of the equipment during the continuous production of multi-specification quartz sand.

[0072] Furthermore, the top of the rotary adjustment seat 34 is provided with a rotation groove 343, the bottom of the guide base 33 is embedded in the rotation groove 343 and slides in cooperation with the inner wall of the rotation groove 343; the second through hole 341, the first through hole 331, and the corresponding sieve hole 13 are arranged coaxially.

[0073] The rotating groove 343 on the top of the rotating adjustment seat 34 and the sliding fit between the rotating adjustment seat 34 and the bottom of the guide base 33 provide radial and axial limits for the circumferential rotation of the rotating adjustment seat 34, ensuring that the rotating adjustment seat 34 rotates coaxially with the guide base 33 and the screen hole 13 throughout the entire process, avoiding axial movement and radial sway during the rotation of the rotating adjustment seat 34, and ensuring the smoothness and consistency of the synchronous sliding of the movable screen plate 31.

[0074] Furthermore, the driving device 32 includes a first gear 321, a second gear 322, and a first motor 323; the first gear 321 is mounted on the rotary adjustment seat 34 and rotates synchronously with the rotary adjustment seat 34; the first motor 323 is installed at the bottom of the cold explosion chamber 11; the second gear 322 is connected to the output shaft of the first motor 323 and meshes with the first gear 321.

[0075] The control terminal 4 is electrically connected to the first motor 323 of each of the aperture adjustment components 3.

[0076] Through the meshing transmission structure of the first gear 321 and the second gear 322, the output torque of the first motor 323 is stably transmitted to the rotary adjustment seat 34, ensuring that the rotation angle of the rotary adjustment seat 34 corresponds stably to the sliding amplitude of the movable screen plate 31, and realizing closed-loop control of the aperture of the adjustable flow channel 312. Through the independent electrical connection between the control terminal 4 and the first motor 323 of each aperture adjustment component 3, the independent aperture adjustment and start / stop control of a single screen hole 13 can be realized. This can realize both synchronous aperture adjustment of all screen holes 13 and differentiated aperture settings of different screen holes 13, further improving the adaptability of the device in the synchronous purification and production of multi-specification quartz sand.

[0077] See Figure 1 , Figures 3-5 Furthermore, the continuous quartz sand purification device also includes multiple auxiliary sealing components 5 and a lifting drive component 6; each of the auxiliary sealing components 5 is placed in the storage cavity 21 and is arranged one-to-one with each of the sieve holes 13; the lifting drive component 6 is installed on the cold explosion purification structure 1, and the lifting drive component 6 is connected to each of the auxiliary sealing components 5 in a transmission manner. The lifting drive component 6 is used to drive each of the auxiliary sealing components 5 to move up and down synchronously along the axial direction of the corresponding sieve hole 13 and abut against each of the movable sieve plates 31 forming the sealing surface 311.

[0078] The lifting drive assembly 6 drives the auxiliary sealing assembly 5, which corresponds one-to-one with the sieve holes 13, to move axially. After the movable sieve plate 31 forms the sealing surface 311, the auxiliary sealing assembly 5 is driven to abut against the lower surface of the movable sieve plate 31, providing axial support for the movable sieve plate 31. This counteracts the vertical pressure of the cooling water and quartz sand in the cold explosion chamber 11, preventing the movable sieve plate 31 from deforming or not fitting properly under high pressure. This improves the sealing reliability of the sieve holes 13 under the sealing state and ensures the effectiveness of the cold explosion purification operation. At the same time, after the purification and screening of a single batch of quartz sand is completed, or before switching to the production of different specifications of quartz sand, the lifting drive assembly 6 can be used to lift and lower the sieve plate 31. Component 6 drives the auxiliary sealing component 5 to reciprocate up and down along the axial direction of the screen hole 13, so that the top of the sealing part 51 of the auxiliary sealing component 5 extends into the axial range of the screen hole 13, and pushes out and cleans the quartz sand particles and fine powder attached to and stuck in the inner wall of the screen hole 13, the surface of the movable screen plate 31 and the joint gap of the adjacent movable screen plates 31. On the one hand, it can prevent residual sand particles from scratching the joint surface of the movable screen plate 31 during the subsequent aperture adjustment process, resulting in sealing failure. On the other hand, it can prevent residual sand particles from the previous batch from being mixed into the subsequent quartz sand products of different specifications, avoiding the problem of particle size mixing, and further improving the adaptability of the device in the purification and production of multi-specification quartz sand.

[0079] Furthermore, the lifting drive assembly 6 includes a movable component 61, a second motor 62, a screw 63, and a support frame 64; the base plate 14 has a first movable through hole 143 extending along the thickness direction of the base plate 14; the bottom of the cold explosion chamber 11 has a corresponding second movable through hole 111 extending axially along the first movable through hole 143; one end of the movable component 61 passes through the first movable through hole 143 and the second movable through hole 111 in sequence, and extends into the storage cavity 21; the outer peripheral surface of the movable component 61 is slidably engaged with the hole wall of the first movable through hole 143 and the hole wall of the second movable through hole 111; the other end of the movable component 61 has a threaded transmission hole 612 extending axially along the first movable through hole 143;

[0080] The top of the cold explosion purification structure 1 is provided with a mounting bracket 16, the second motor 62 is mounted on the mounting bracket 16 and is electrically connected to the control terminal 4; the screw 63 extends axially along the first movable through hole 143, and one end of the screw 63 is connected to the output shaft of the second motor 62; the other end of the screw 63 is screwed into the threaded transmission hole 612;

[0081] The mounting bracket 16 has at least two limiting guide grooves 161, each of which extends along the axial direction of the screw 63 and is arranged radially opposite to each other along the moving part 61; the outer peripheral surface of the moving part 61 is provided with a limiting protrusion 611, each of which is embedded in the limiting guide groove 161 on the corresponding side and slides in cooperation with the inner wall of the corresponding limiting guide groove 161.

[0082] The support frame 64 is installed at one end of the movable member 61 that extends into the storage cavity 21, and slides synchronously with the movable member 61; each of the auxiliary sealing components 5 is installed on the support frame 64.

[0083] The second motor 62 drives the screw 63 to rotate, which, in conjunction with the screw 63 engaging with the threaded transmission hole 612 of the movable part 61, and the limiting guide groove 161 of the mounting bracket 16 and the limiting protrusion 611 of the movable part 61, converts the rotational motion of the second motor 62 into the axial linear lifting motion of the movable part 61. This controls the contact stroke and contact force between the auxiliary sealing assembly 5 and the movable screen 31, ensuring the consistency of the sealing and reinforcement effect. The movable part 61 passes through the first movable through hole 143 of the base plate 14 and the second movable through hole at the bottom of the cold explosion chamber 11. The double-hole sliding fit structure of the moving through hole 111 provides radial limit for the axial lifting of the moving part 61, avoiding radial sway during the lifting process of the moving part 61, and ensuring that each auxiliary sealing component 5 on the support frame 64 can be coaxially connected with the corresponding screen hole 13; through the second motor 62 electrically connected to the control terminal 4, the lifting action of the auxiliary sealing component 5 can be automatically controlled, and linked with the sealing and opening action of the aperture adjustment component 3, so that the sealing and avoidance actions can be completed without manual operation, which is suitable for the continuous and automated multi-specification quartz sand purification production needs of the equipment.

[0084] Furthermore, the auxiliary sealing assembly 5 is provided with a sealing part 51, a guide post 52 and an elastic buffer 53; the guide post 52 is located at the bottom of the sealing part 51 and extends along the axial direction of the corresponding sieve hole 13; the top of the sealing part 51 is used to abut against the plurality of movable sieve plates 31 in the corresponding sieve hole 13.

[0085] The support frame 64 has guide holes 641 corresponding to each of the auxiliary sealing components 5. The guide holes 641 extend along the axial direction of the corresponding guide post 52. The guide post 52 passes through the corresponding guide hole 641 and slides in cooperation with the hole wall of the corresponding guide hole 641.

[0086] The elastic buffer 53 is sleeved on the outer peripheral surface of the guide post 52, and the two ends of the elastic buffer 53 abut against the bottom of the sealing part 51 and the top of the support frame 64, respectively; the elastic buffer 53 is used to apply an elastic pre-tightening force to the sealing part 51 that extends into the corresponding screen hole 13 to abut against the movable screen plate 31.

[0087] Through the cooperative structure of the sealing part 51, guide post 52, and elastic buffer 53, when the sealing part 51 abuts against the movable screen plate 31, the compression deformation of the elastic buffer 53 provides a continuous axial elastic preload to the sealing part 51. This automatically compensates for the wear, deformation, and vibration displacement of the movable screen plate 31, ensuring that the sealing part 51 always tightly abuts against the lower surface of the movable screen plate 31. This not only guarantees the sealing performance in the sealing state but also avoids deformation and damage to the movable screen plate 31 caused by rigid contact. Furthermore, through the sliding fit structure between the guide post 52 and the guide hole 641 of the support frame 64... It provides stable guidance for the axial extension and retraction of the sealing part 51, and avoids radial displacement of the sealing part 51 during lifting and contact. Through the independent elastic buffer structure of each screen hole 13 corresponding to a single set of auxiliary sealing components 5, it can adapt to the height difference and deformation of the movable screen plate 31 of different screen holes 13. Even if there are assembly errors and wear differences in the movable screen plate 31 of different screen holes 13, uniform contact can be achieved through the independent deformation of the corresponding elastic buffer 53, ensuring that the sealing and reinforcement effect of each screen hole 13 is consistent, and improving the sealing reliability and operational stability of the device during long-term operation.

[0088] The elastic buffer 53 is preferably a cylindrical helical compression spring, which is coaxially sleeved on the outer circumferential surface of the guide post 52, and its two axial ends stably abut against the bottom end face of the sealing part 51 and the top end face of the support frame 64.

[0089] See Figure 1 , Figure 4 Furthermore, the outer peripheral surface of the cold explosion purification structure 1 is provided with a water supply pipe 17, which is connected to the cold explosion cavity 11 and is used to connect with external cooling water supply equipment; a first control valve 7 is installed on the water supply pipe 17, which is used to control the opening and closing of the water supply pipe 17.

[0090] The bottom of the storage structure 2 is provided with a sand extraction port 22, which is connected to the storage cavity 21; a second control valve 8 is installed at the sand extraction port 22, which is used to control the opening and closing of the sand extraction port 22.

[0091] The first control valve 7 and the second control valve 8 are electrically connected to the control terminal 4, respectively.

[0092] Through the water supply pipe 17 connected to the cold explosion chamber 11 and the first control valve 7, the cooling water in the cold explosion chamber 11 can be automatically replenished and replaced. With the electrical connection control of the control terminal 4, the injection volume, injection speed and water replacement frequency of the cooling water can be controlled according to the cold explosion purification process requirements of different specifications of quartz sand, so as to ensure that quartz sand of different particle size and grade can obtain the best cold explosion purification effect. Through the sand outlet 22 at the bottom of the storage structure 2 and the second control valve 8, the qualified quartz sand after screening can be automatically and continuously discharged, and the finished product can be collected without stopping the machine, which is suitable for the continuous purification production needs of different specifications of quartz sand.

[0093] The first control valve 7 is preferably an explosion-proof soft-seal electric regulating ball valve, and the second control valve 8 is preferably a wear-resistant hard-seal electric regulating ball valve. The explosion-proof soft-seal electric regulating ball valve can simultaneously realize the stepless adjustment of pipeline opening and closing and cooling water flow under the linkage control of the control terminal 4, matching the differentiated requirements of different specifications of quartz sand cold explosion purification processes for cooling water injection volume, injection speed, and water change frequency. The wear-resistant hard-seal electric regulating ball valve can effectively avoid quartz sand particles from getting stuck and blocking the material. Its hard-seal valve seat can withstand the long-term scouring and wear of water-sand mixed media, extending the service life of the valve and adapting to the production capacity requirements and continuous production rhythm of different specifications of quartz sand.
