Description

Technical Field

[0001] The invention relates to the technical field of quartz sand processing, in particular to high-temperature quartz sand processing equipment with dual processing technology. Background Art

[0002] At present, quartz sand is quartz particles obtained by crushing quartz stone. It has the characteristics of silicate minerals with high hardness, wear resistance and stable chemical properties. Its main component is silicon dioxide (SiO 2 ), plays a key raw material role in the industrial field; In order to remove impurities on its surface and inside, such as iron oxide, clay, mica, etc., to improve purity. After the quartz sand is crushed, it will be washed with water. This physical cleaning process is usually used in combination with other purification processes. It can be used as a pretreatment step to remove dirt and prepare for subsequent chemical purification processes such as acid washing to ensure that the quartz sand meets the purity requirements in high-end applications such as glass manufacturing and semiconductor production. The drying of quartz sand after water washing is not only an indispensable part of the quartz sand processing flow, but also a key step to ensure the quality and performance of the final product. The core goal of this process is to completely remove the residual free water and attached wet film in the quartz sand, so as to avoid the adverse effects of moisture on the physical properties, chemical stability and subsequent processing of the quartz sand; However, the washed quartz sand passes through a discharge valve and is transferred by gravity directly into a drying device. Since the washed quartz sand has a high water content or uneven particle size distribution, the fluidity of the washed quartz sand will deteriorate, causing the quartz sand to agglomerate and agglomerate during the drying process, resulting in a high moisture content in the dried quartz sand. This not only reduces the purity of the product, but also affects its performance in subsequent processing or use. Moreover, in subsequent processing, such as grinding, screening, mixing and other processes, low-purity quartz sand will lead to reduced processing efficiency and unstable product quality.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The present invention optimizes the pre-drying treatment process of washed quartz sand through a segmentation structure and a transmission structure. In the feed box and the feed barrel, the washed quartz sand is effectively segmented by the segmentation structure. This segmentation not only helps to reduce the contact and friction between the quartz sands, but also reduces the agglomerates formed due to excessive squeezing between particles. Subsequently, the segmented quartz sand falls evenly on the conveyor belt. This process further breaks up the agglomeration and agglomeration of the quartz sand, thereby significantly improving the fluidity of the quartz sand in the feed barrel. This improved fluidity not only helps to improve the drying efficiency, but also reduces the problem of uneven drying caused by agglomeration, thereby ensuring the quality and performance of the quartz sand in the subsequent processing process; The circulating heat transfer structure of the present invention effectively utilizes the heat energy in the tumbling drying structure to transfer the heat energy released in the discharge barrel to the feed barrel. The quartz sand divided on the conveyor belt is pre-dried in the feed barrel, which can increase the surface temperature of the quartz sand, thereby accelerating the evaporation process of water and helping to improve the drying efficiency. Pre-drying can significantly reduce the moisture content of the quartz sand and reduce the liquid bridge effect caused by moisture, thereby reducing the agglomeration phenomenon between particles. Moreover, through pre-drying, the fluidity of the quartz sand is improved, which is helpful for subsequent processing and handling processes and reduces the agglomeration problem caused by poor fluidity.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] See also Figure 1-13 The present invention provides a technical solution: a quartz sand high-temperature processing equipment with dual processing technology, including a fixed support structure 100, the fixed support structure 100 includes a support frame 101, and a support base 102 fixedly connected to the support frame 101 and located at both ends of the support frame 101; the support frame 101 and the support bases 102 at both ends provide a stable base for the entire equipment.

[0019] The tumble drying structure 200 includes a drying cylinder 201 rotatably connected to the support base 102, a feeding cylinder 202 rotatably connected to one end of the drying cylinder 201 and located on one side of the support base 102, a feeding box 203 fixedly connected to the feeding cylinder 202 at one end away from the drying cylinder 201, and a discharging cylinder 204 rotatably connected to the other end of the drying cylinder 201 and located on one side of the support base 102; the drying cylinder 201 is the core component of the tumble drying structure 200, and the interior of the drying cylinder 201 provides a rotating space for the quartz sand, so that the stone The quartz sand keeps rolling inside, and the drying cylinder 201 adopts high-temperature heating and microwave heating methods, which increases the chance of the quartz sand contacting with heat energy. The washed quartz sand enters from the feed cylinder 202 and the feed box 203 at one end of the drying cylinder 201. As the cylinder rotates, the washed quartz sand keeps rolling inside the cylinder, which increases the chance of the quartz sand contacting with heat energy, thereby accelerating the evaporation of water. The heat source transfers heat through the shell or inner wall of the drying cylinder 201, so that the washed quartz sand is quickly dried, and the dried quartz sand is discharged from the discharge port on the discharge cylinder 204.

[0020] The transmission structure 300 includes a motor 301 fixedly connected to the feed barrel 202 and located below the feed box 203, a main rotating wheel 302 fixedly connected to the motor 301 and located between the feed barrel 202 and the motor 301, a transmission belt 303 rotatably connected to the main rotating wheel 302, a driving shaft 304 fixedly connected to the surface of the main rotating wheel 302 and one end of which rotates and passes through the side of the feed barrel 202, and the other end of which rotates and is embedded in the other side of the feed barrel 202, an active roller 305 fixedly connected to the surface of the active rotating shaft 304 and located inside the feed barrel 202, and a transmission belt 306 rotatably connected to the surface of the active roller 305, located directly below the connection between the feed box 203 and the feed barrel 202, and extending inside the feed barrel 202 to one end of the drying barrel 201; the motor 301 provides the necessary power to drive the rotation of the entire transmission belt 306 to ensure the continuous flow of quartz sand on the transmission belt 306. The main wheel 302 transmits the rotational motion of the motor 301 to the transmission belt 303, which further drives the rotation of the slave wheel 401. The rotation of the main wheel 302 can drive the rotation of the active shaft 304 and the active roller 305, thereby driving the transmission belt 306 to rotate inside the feed cylinder 202 as the main power source, and then transferring the quartz sand in the feed box 203 to the inside of the drying cylinder 201 for drying.

[0021] The splitting structure 400 includes a driven wheel 401 rotatably connected to the transmission belt 303, a transmission shaft 402 fixedly connected to the driven wheel 401 and rotatably connected to the outside of the feed box 203 at one end, a bevel gear 1 403 fixedly connected to the other end of the transmission shaft 402 and located on the outside of the driven wheel, and a bevel gear 2 404 meshingly connected to the surface of the bevel gear 1 403; the rotation of the transmission belt 303 drives the rotation of the driven wheel 401, the rotation of the driven wheel 401 drives the rotation of the transmission shaft 402, the rotation of the transmission shaft 402 can drive the rotation of the bevel gear 1 403, the rotation of the bevel gear 1 403 can drive the rotation of the bevel gear 2 404, and the rotation of the bevel gear 2 404 can drive the rotation of the connecting shaft 405, thereby providing power for the operation of the entire splitting piece 413.

[0022] The circulating heat transfer structure 500 includes a sleeve 501 fixedly connected to the surface of the discharge barrel 204 and close to the side of the support base 102, a mounting sleeve 502 fixedly connected to the sleeve 501 and symmetrical with respect to the discharge barrel 204, and a transmission pipe 503 fixedly connected to the connecting sleeve 1 and symmetrical with respect to the discharge barrel 204. The sleeve 501 is mainly used to provide a stable connection point on the surface of the discharge barrel 204, so that the heat transferred from the drying barrel 201 in the discharge barrel 204 is transferred along the mounting sleeve 502 on the sleeve 501, ensuring the stability of the entire circulating heat transfer structure 500 and avoiding loosening of the circulating heat transfer structure 500 due to thermal expansion or vibration. The mounting sleeve 502 is used to connect the sleeve 501 and the transmission pipe 503, ensuring that the heat transferred in the sleeve 501 is transferred along the transmission pipe 503 to the feed barrel 202, thereby not only pre-treating the quartz sand on the conveyor belt 306, but also realizing the recycling of heat in the drying barrel 201.

[0023] The conveyor belt 306 has a cross section, wherein the upper cross section has a wave shape along the belt length direction, and the wave shape is composed of wave crests and wave troughs arranged at equal intervals, the point where the vertical line at the midpoint of the wave crest and the lower surface of the conveyor belt 306 intersect is set as the center of the circle m, the vertical line at the midpoint of the wave crest is set as the y-axis, and the horizontal line at the lower surface of the conveyor belt 306 is set as the x-axis, wherein the distance between the wave crest and the wave trough is L, the vertical distance between the top of the wave crest and the lowest point of the wave trough is H, and the value of H is smaller than the value of L; the wave-shaped surface increases the contact points between the conveyor belt 306 and the quartz sand, making the distribution of the quartz sand on the conveyor belt 306 more uniform, and reducing the possibility of quartz sand accumulation. The height H between the wave crest and the wave trough, that is, the convex part of the wave shape, can be used as a simple stirrer to help turn the quartz sand, thereby improving the mixing uniformity of the quartz sand during the transmission process. The quartz sand does not contact the conveyor belt 306 continuously and smoothly, which reduces the actual contact area between the quartz sand and the belt surface and reduces the possibility of adhesion. The wavy design is conducive to the discharge of liquid and reduces the situation where the quartz sand adheres to the conveyor belt 306 due to high humidity.

[0024] The rolling action of the quartz sand on the wavy conveyor belt 306 helps to break the liquid bridge formed by water between the quartz sand, which is one of the main factors for the agglomeration and agglomeration of the quartz sand. The wavy upper surface of the conveyor belt 306 increases the distance between the quartz sand particles, reduces the contact opportunities between the particles, and thus reduces the mutual adsorption and agglomeration between the particles. The wavy design increases the surface area of ​​the quartz sand, so that the hot air transmitted from the discharge barrel 204 to the feed barrel 202 can contact the quartz sand more effectively, accelerates the evaporation of water on the surface of the quartz sand, performs drying pretreatment on the quartz sand on the conveyor belt 306, and reduces the agglomeration and agglomeration caused by water.

[0025] The feed drum 202 is rotatably connected to one end away from the motor 301 and close to the support base 102, and has two ends embedded and rotatably connected to the inner side of the feed drum 202 and a driven shaft 308 on the same horizontal plane as the center point of the driving shaft 304; the driven shaft 308 is fixedly connected on the surface of a driven roller 309, whose two ends are arranged inside the feed drum 202 and on the same plane as the driving roller 305, and the surface of which is rotatably connected to the transmission belt 306; the transmission belt 306 is rotatably connected to a transmission component 307 located on the inner side of the feed drum 202 just below the end away from the motor 301; the driven roller 309 shaft is used to fix and support the rotation of the driven roller 309, the driving shaft 304 and the driven shaft 308 are on the same horizontal plane, and the driving roller 305 and the driven roller 309 are on the same plane, which can ensure the stability of the transmission belt 306 during the transmission process. The driven roller 309 is a key supporting point during the transmission of the transmission belt 306. It transmits the power of the motor 301 to the entire transmission system through interaction with the active roller 305, ensuring the smooth transportation of the quartz sand. The surface of the feed box 203 is fixedly connected to a fixed frame 2031 that is symmetrical with respect to the feed cylinder 202; the fixed frame 2031 is used to ensure the stability of the feed box 203 during operation.

[0026] Bevel gear 2 404 is fixedly connected to the upper top surface above transmission shaft 402 with a connecting shaft 405 perpendicular to transmission shaft 402. The connecting shaft 405 is movably connected to a support frame 406 at the center in the vertical direction, one end of which is fixedly connected to the surface of fixed frame 2031; support frame 406 is used to fix and support the rotation of connecting shaft 405.

[0027] A turntable 407 is fixedly connected to the upper surface of the end of the connecting shaft 405 away from the bevel gear 2 404, and a connecting block 1 408 is fixedly connected to the edge of the turntable 407 away from the center point of the turntable 407, and the surface of the connecting block 1 408 is rotatably connected to a connecting rod 1 409 located inside the feed box 203 and above the turntable 407, and the end of the connecting rod 1 409 away from the connecting block is fixedly connected to a connecting block 2 410, and the surface of the connecting block 2 410 is rotatably connected to a connecting rod 2 411 located inside the feed box 203 and above the connecting rod 1 409; the surface of the connecting rod 2 411 is fixedly connected to a support shaft 412, one end of which is embedded and rotatably connected to the inside of the feed box 203 and located above the connection between the feed box 203 and the feed cylinder 202, and the surface of the support shaft 412 is rotatably connected to a plurality of dividing pieces 413 located directly above the conveyor belt 306; The connecting shaft 405 is a key component for transmitting power. The power transmitted by the bevel gear 2 404 rotates the connecting shaft 405.

[0028] Power is transmitted to the turntable 407 through the connecting shaft 405 to realize long-distance transmission of energy. The rotation of the turntable 407 provides power for the subsequent reciprocating swing of the connecting rod 1 409. The swing of the connecting rod 1 409 drives the connecting rod 2 411 to swing back and forth in the clamping block 415, thereby driving the reciprocating rotation of the support shaft 412 to drive the swing of the dividing piece 413, and divide the quartz sand falling from the feed port of the feed box 203. The large pieces of quartz sand are divided into small parts and evenly dropped onto the conveyor belt 306. Then the conveyor belt 306 transports the quartz sand to the drying cylinder 201 to prevent the quartz sand from agglomerating and agglomerating during the drying process.

[0029] The supporting frame 101 is fixedly connected with a power member 103, the feeding cylinder 202 is fixedly connected with a second sleeve 505 corresponding to the first sleeve 501, and the second sleeve 505 is fixedly connected with a second installation sleeve 504 matching the transmission tube 503 and corresponding to the first installation sleeve 502; the power member 103 is used to drive the rotation of the entire drying cylinder 201, and the transmission tube 503 transmits the heat in the discharge cylinder 204 to the feeding cylinder 202 through the second installation sleeve 504 and the second sleeve 505, so as to pre-treat the quartz sand on the conveyor belt 306 With the point of the cross section of the connecting axis 405 as the center O and the center O as the starting point, along the horizontal direction radius of the circular cross section of the connecting axis 405, the rightward extending direction is set to be the X axis, and along the vertical direction radius of the circular cross section of the connecting axis 405, the upward extending direction is set to be the X axis; The dividing piece 413 includes a protruding block 4131 and a guide block 4132. The protruding block 4131 is located directly above the X-axis and is symmetrical about the Y-axis. From the connection between the protruding block 4131 and the X-axis to the connection between the protruding block 4131 and the Y-axis, the inner diameter of the cross section of the protruding block 4131 has a tendency to gradually decrease, and a tip is formed at the connection between the protruding block 4131 and the Y-axis. The guide block 4132 is located directly below the X-axis, and the guide block 4132 is symmetrical about the Y-axis. From the connection point of the guide block 4132 and the X-axis to the connection point of the guide block 4132 and the opposite direction of the Y-axis, the inner diameter of the cross section of the guide block 4132 has a tendency to gradually decrease, and forms an arc-shaped end at the connection point of the guide block 4132 and the opposite direction of the Y-axis. The function of the convex block 4131 is to divide the washed quartz sand falling from the feed box 203. During the falling process of the quartz sand, the convex block 4131 and the guide block 4132 are in a state of reciprocating swing in the same direction. The washed quartz sand falls onto the convex block 4131 under the action of gravity. The tip of the convex block 4131 will divide the quartz sand. The divided quartz sand is evenly distributed on the conveyor belt 306 along the surface of the guide plate and the holes 414 on the surface of the guide plate, and is transmitted to the transmission component 307 through the conveyor belt 306.

[0030] The transmission component 307 includes a fixed shaft 1 3072 whose two ends are rotatably connected to the inner surface of the feed cylinder 202, a conveying member 3071 fixedly connected to the surface of the fixed shaft 1 3072 and located below the conveying belt 306, and located inside the feed cylinder 202, a fixed shaft 2 3073 rotatably connected to one end of the conveying member 3071 away from the drying cylinder 201, a cleaning cylinder 3074 fixedly connected to the surface of the fixed shaft 2 3073 and located below the conveying belt 306, and a limiting member 3075 whose one end is fixedly connected to the surface of the conveying member 3071 and the other end is fixedly connected to the inner surface of the feed cylinder 202 and located on one side of the cleaning cylinder 3074; When the quartz sand on the conveyor belt 306 falls on the conveyor member 3071, since the length of the portion of the conveyor member 3071 away from the fixed axis 3072 is greater than the length of the portion of the conveyor member 3071 close to the fixed axis 3072, when the quartz sand is transported on the conveyor member 3071, the length of the portion of the conveyor member 3071 close to the fixed axis 3072 is lifted and moved closer to the lower surface of the conveyor belt 306 using the lever principle. At this time, the cleaning brush cylinder 3074 will fit the lower surface of the rotating conveyor belt 306, The lower surface of the conveyor belt 306 is cleaned and brushed. The continuous brushing action of the brush cylinder 3074 can effectively remove the residual quartz sand on the conveyor belt 306, keep the surface of the conveyor belt 306 smooth, reduce the stickiness of the surface of the conveyor belt 306 after use, and prevent the accumulation and agglomeration of subsequent quartz sand on the surface of the conveyor belt 306, thereby improving the transportation efficiency of the quartz sand on the conveyor belt 306. The limiter 3075 limits the height of the brush cylinder 3074 to prevent the brush cylinder 3074 from being too high and affecting the transmission of the conveyor belt 306.

[0031] The limiting member 3075 includes a fixed block 3075-1 having one end fixedly connected to the inner bottom surface of the feed barrel 202, an anti-slip groove 3075-2 opened inside the fixed block 3075-1, an anti-slip block 3075-3 having one end slidably connected to the anti-slip groove 3075-2 and the other end fixedly connected to the surface of the conveying member 3071, a telescopic cylinder 3075-4 fixedly connected to the anti-slip groove 3075-2, a telescopic column 3075-5 having one end slidably connected to the inside of the telescopic cylinder 3075-4 and the other end fixedly connected to the surface of the anti-slip block 3075-3, and a spring 3075-6 having one end fixedly connected to the lower surface of the anti-slip block 3075-3 and the other end fixedly connected to the surface of the telescopic sleeve and located on the surface of the telescopic column 3075-5. The transmission member and the feed cylinder 202 are integrated into a whole by connecting the anti-dropping block 3075-3 and the fixing block 3075-1 under the transmission member. Each time the transmission member is lifted, the anti-dropping block 3075-3 pulls the telescopic rod to slide in the telescopic cylinder 3075-4. At this time, the spring 3075-6 plays a key role. When the transmission member drops or loses external force, it pushes the telescopic rod back to its original position, ensuring that the entire limiter 3075 system can work stably and repeatedly.

[0032] Working principle: The operator turns on the power of the entire device, and the motor 301 starts to work. When the motor 301 receives the start signal, it starts to rotate. The motor 301 is the power source of the transmission structure 300. The rotation of the motor 301 is transmitted to the slave wheel 401 through the main wheel 302 and the transmission belt 303, thereby driving the rotation of the active shaft 304 and the active roller 305. The rotation of the active roller 305 drives the movement of the transmission belt 306, providing the necessary power for the transmission of quartz sand. The start of the motor 301 marks the beginning of the entire drying process and provides a stable power source for subsequent steps. The movement of the transmission belt 306 ensures that the quartz sand can continuously, smoothly and evenly enter the drying cylinder 201 for drying.

[0033] As the conveyor belt 306 moves, the quartz sand falls from the feed port of the feed box 203 onto the conveyor belt 306. The segmentation structure 400 is composed of a rotating wheel 401, a transmission shaft 402, a bevel gear 1 403 and a bevel gear 2 404, which together drive the rotation of the connecting shaft 405 and the turntable 407. The connecting block 1 408 and the connecting rod 1 409 on the turntable 407 drive the connecting block 2 410 and the connecting rod 2 411 to swing back and forth, thereby driving the convex tip block 4131 and the guide block 4132 to swing. The washed quartz sand, under the guidance of gravity, will gradually settle to the tip of the convex tip block 4131, and the sharp parts of these tips will split the quartz sand. Subsequently, the segmented quartz sand is evenly spread on the conveyor belt along the surface of the guide plate and the hole groove 414 on the plate. The dividing structure 400 divides the large pieces of quartz sand into small pieces, thereby preventing the quartz sand from agglomerating and agglomerating during the drying process. The design of the guide block 4132 enables the quartz sand to be evenly distributed on the conveyor belt 306, thereby improving the drying efficiency.

[0034] The segmented quartz sand is gradually brought closer to the drying cylinder 201 by the conveyor belt 306. At this time, the wave shape of the conveyor belt 306 begins to play a role. The wavy surface increases the contact points between the conveyor belt 306 and the quartz sand, making the distribution of the quartz sand on the conveyor belt 306 more uniform. At the same time, the height difference between the crest and the trough can be used as a simple agitator to help turn the quartz sand and improve its mixing uniformity during the transmission process. The wavy conveyor belt 306 design improves the mixing uniformity of the quartz sand during the transmission process and reduces the possibility of agglomeration and agglomeration. The distance between the quartz sand particles is increased, the contact opportunities between the particles are reduced, and thus the mutual adsorption between the particles is reduced.

[0035] After the quartz sand passes through the transmission component 307 and enters the drying cylinder 201, the quartz sand tumbles continuously as the cylinder rotates. The drying cylinder 201 uses high temperature heating and microwave heating to increase the chances of the quartz sand coming into contact with heat energy. At the same time, the tumbling action helps to break the liquid bridge formed by water between the quartz sands, further reducing the phenomenon of agglomeration and agglomeration. The tumbling action allows the quartz sand to come into contact with heat energy more fully, accelerating the evaporation of water. The liquid bridge formed by water between the quartz sands is broken, reducing the possibility of agglomeration and agglomeration. In the process of the conveyor belt 306 transporting the quartz sand to the transmission assembly 307 and then entering the drying cylinder 201 through the transmission assembly 307, some quartz sand or other impurities may remain on the conveyor belt 306. In order to keep the conveyor belt 306 clean and smooth, the cleaning cylinder 3074 starts to play a role. When the quartz sand on the conveyor belt 306 falls on the conveying member 3071, the length of the part away from the fixed axis 1 3072 is greater than the length of the part close to the fixed axis 1 3072, and the part of the conveyor member 3071 close to the fixed axis 1 3072 will be lifted toward the lower surface of the conveyor belt 306. At this time, the cleaning cylinder 3074 will fit the lower surface of the conveyor belt 306 in rotation and clean the lower surface of the conveyor belt 306. The continuous cleaning action of the cleaning cylinder 3074 can effectively remove the quartz sand and impurities remaining on the conveyor belt 306. The surface of the conveyor belt 306 is kept smooth and clean, and the stickiness of the surface of the conveyor belt 306 after use is reduced. This prevents subsequent quartz sand from accumulating and agglomerating on the surface of the conveyor belt 306, thereby improving the transportation efficiency of the quartz sand.

[0036] During the operation of the cleaning cylinder 3074, the limiter 3075 plays a key role. It is composed of a fixed block 3075-1, an anti-slip groove 3075-2, an anti-slip block 3075-3, a telescopic cylinder 3075-4, a telescopic column 3075-5 and a spring 3075-6. When the transmission member is in the process of lifting, the anti-slip block 3075-3 will pull the telescopic rod to slide in the telescopic cylinder 3075-4. At this time, the spring 3075-6 plays a key role. It will push the telescopic rod back to its original position when the transmission member descends or loses external force. This ensures that the entire limiter 3075 system can work stably and repeatedly. The design of the limiter 3075 ensures the stability of the transmission member during the lifting and lowering process. The addition of the spring 3075-6 enables the limiter 3075 system to automatically reset, thereby improving the reliability and durability of the system.

[0037] The quartz sand after drying is discharged from the discharge port of the discharge barrel 204. At this time, the moisture in the quartz sand has been largely removed, achieving the purpose of drying. The discharged quartz sand can be subsequently packaged, stored or further processed. The quality of the dried quartz sand is significantly improved, meeting the needs of subsequent processing or use. The entire drying process is efficient and energy-saving, reducing production costs.

[0038] In the process of drying quartz sand, the circulating heat transfer structure 500 plays a vital role. The components such as the collar 1 501, the mounting sleeve 1 502 and the transmission tube 503 together form a heat transfer channel. The heat transferred from the drying cylinder 201 in the discharge cylinder 204 is transferred along the mounting sleeve 1 502 on the collar 1 501, and then enters the feed cylinder 202 through the transmission tube 503. In this way, the quartz sand on the conveyor belt 306 can be pre-treated, and the heat in the drying cylinder 201 can be circulated.

[0039] Through the circulating heat transfer structure 500, the heat in the drying cylinder 201 can be effectively recovered and reused. This avoids the waste of heat and improves the energy utilization efficiency of the entire drying process. The recycling of heat reduces the demand for new heat sources, thereby reducing energy consumption. This is of great significance for reducing production costs and improving economic benefits. The circulating heat transfer structure 500 helps to maintain a stable temperature in the drying cylinder 201, which is conducive to the uniform drying of quartz sand and ensuring the drying quality. In addition, the transmission pipe 503 in the circulating heat transfer structure 500 can effectively capture and process the dust generated during the drying process, thereby improving the working environment and reducing the risk of workers suffering from occupational diseases.

[0040] The circulating heat transfer structure 500 allows the heat in the discharge cylinder 204 to enter the feed cylinder 202 along the collar 1 501 and the transmission tube 503, and preheat the quartz sand on the conveyor belt 306. This helps to speed up the drying speed of the quartz sand and improve the drying efficiency. The preheating treatment can remove part of the moisture from the quartz sand before entering the drying cylinder 201, thereby reducing the drying time in the drying cylinder 201. This helps to avoid the problem of overheating or uneven drying of the quartz sand during the drying process, and ensure the drying quality.
