Description

Technical Field

[0001] This invention relates to the field of quartz sand drying technology, and in particular to a temperature control device for resin-coated quartz sand used in fracturing. Background Technology

[0002] Quartz sand is quartz particles produced by crushing and screening quartz stone. It is a non-metallic mineral, and its main mineral component is silicon dioxide. Quartz sand can be classified according to quality into ordinary quartz sand, refined quartz sand, high-purity quartz sand, fused quartz sand, and silica powder, etc.

[0003] After washing, quartz sand needs to be dried during the production process. However, the high moisture content of the washed quartz sand makes it prone to clumping. Direct drying makes it difficult to separate the clumped quartz sand, resulting in uneven heating and insufficient drying, which affects subsequent use. Furthermore, the moisture content of the washed quartz sand varies, meaning that while some particles are dried, others still contain moisture. Quartz sand with low moisture content is over-dried, while quartz sand with high moisture content is under-dried, leading to significant differences in the quality of the dried quartz sand. Moreover, it is difficult to monitor the changes in moisture content of the quartz sand in real time during the drying process, making it difficult to ship the quartz sand out promptly after drying.

[0004] Therefore, it is necessary to design a quartz sand temperature control treatment device that can pre-treat quartz sand to reduce its moisture content and break it up to ensure the drying effect. This would solve the problems of existing devices where clumps of quartz sand cannot be heated evenly during drying, resulting in insufficient drying, and the significant differences in the quality of dried quartz sand due to varying degrees of dryness after washing.

[0012] Preferably, it also includes a pretreatment mechanism for pre-drying the washed quartz sand.

[0015] Preferably, it also includes a discharge mechanism for discharging dust into a pretreatment box for recycling.

[0016] The beneficial effects of the present invention are as follows: 1. The device can tap the cleaned quartz sand to prevent it from clumping, thus avoiding uneven drying caused by clumping, and also preventing the clumped quartz sand from blocking the channel.

[0017] 2. This device opens the channel between the rotating chamber and the processing cylinder by pressing down the sliding pressure rod and the lifting baffle block with a fixed pressure plate, allowing the quartz sand to enter the processing cylinder. Since the fixed pressure plate pushes the lifting baffle block down for the same amount of time each time, the weight of quartz sand received on the lifting receiving plate is equal after the sliding pressure rod has completely passed the fixed pressure plate.

[0018] 3. The lifting receiving plate slides downward under the gravity of the quartz sand. During the drying process, the moisture content of the quartz sand gradually decreases, the weight of the quartz sand decreases, and the lifting receiving plate rises continuously. When the moisture content of the quartz sand reaches the specified range, the limit block just disengages from the guide rod and releases the restriction on the lifting frame. The lifting frame is supported by the spring and pushed upward, driving the rotating baffle to rotate, so as to automatically open the discharge hole on the fixed base plate, and the dried quartz sand automatically falls downward.

[0019] 4. During the rotation of the processing cylinder by the rotating frame, when there is quartz sand in the processing cylinder, the sliding unlocking rod has not yet risen to the sliding block. At this time, the L-shaped rod is limited by the sliding block. After the sliding pressure rod contacts the fixed pressure plate, the sliding pressure rod will not push the L-shaped rod down, so as to prevent the lifting baffle block from sliding down and opening during the drying process. After drying is completed, the sliding unlocking rod rises to the highest position and releases the restriction of the sliding block on the L-shaped rod. At this time, the sliding pressure rod can push the L-shaped rod and the lifting baffle block down through the second downward pressure spring and add new quartz sand into the processing cylinder to ensure the normal operation of the drying process.

[0020] 5. The temperature of the dried quartz sand is relatively high. When the quartz sand comes into contact with the temperature regulating push block, the temperature regulating push block expands due to heat, causing the wedge block to get stuck on the sliding block. When the temperature of the quartz sand decreases, the temperature regulating push block contracts due to the decrease in temperature. The wedge block drives the sliding block to disengage from the processing cylinder. Then, after the L-shaped pressure rod comes into contact with the fixed lower pressure plate, the L-shaped pressure rod can drive the lifting clamping frame to descend, so as to open the outlet on the receiving baffle and discharge the cooled quartz sand downward.

[0021] 6. The quartz sand has a high moisture content after washing. Pretreatment reduces the moisture content of the quartz sand to reduce the subsequent drying load and shorten the drying time. The circulating treatment prevents substandard quartz sand from entering the drying process and affecting the drying process. During the pretreatment process, the sliding scraper slides up and down along the feeding ramp to prevent quartz sand from accumulating and causing blockage of the feeding ramp, thus ensuring stable material transportation in the pretreatment stage.

[0022] 7. During the cooling process, the high-temperature exhaust gas is discharged into the pretreatment box, realizing the recovery and utilization of exhaust gas waste heat, improving energy utilization efficiency, and reducing heat waste. Attached Figure Description

Detailed Implementation

[0037] The present invention will now be described in detail with reference to the accompanying drawings.

[0038] Example 1: A temperature control device for resin-coated quartz sand used in fracturing, such as... Figures 1-13As shown, the system includes a support base 1, a drive motor 101, a fixed cylinder 3, a rotating cylinder 3002, a disintegrating frame 3004, a rotating frame 301, a processing cylinder 302, a rotating chamber 4, a feeding frame 401, a fixed top plate 402, a drying mechanism, and a cooling mechanism. The drive motor 101 is fixedly connected to the support base 1, and the fixed cylinder 3 is also fixedly connected to the support base 1. The rotating frame 301 is rotatably connected to the bottom of the fixed cylinder 3. The output shaft of the drive motor 101 is connected to the rotating frame 301, enabling the drive motor 101 to drive the rotating frame 301 to rotate. The rotating cylinder 3002 is fixedly connected to the rotating frame 301 and rotates with it. The disintegrating frame 3004 is rotatably connected to the top of the rotating cylinder 3002. A rotating frame 3004 is mounted on the top of the fixed cylinder 3. The rotating chamber 4 is connected to a dispersing frame 3004, which passes through and rotates with the rotating chamber 4. During the rotation of the rotating chamber 4, the dispersing frame 3004 will beat the quartz sand in the rotating chamber 4 to disperse the quartz sand. A fixed top plate 402 is rotatably connected to the rotating chamber 4. The fixed top plate 402 is fixedly connected to the supporting base frame 1. A feed frame 401 is fixedly connected to the fixed top plate 402 and communicates with the rotating chamber 4. A processing cylinder 302 is fixedly connected to the rotating frame 301. An outlet is opened at the bottom of the processing cylinder 302. The top of the processing cylinder 302 is fixedly connected to the rotating chamber 4. The rotating frame 301 can drive the rotating chamber 4 to rotate through the processing cylinder 302. A drying mechanism is installed in the processing cylinder 302 and can dry the quartz sand. A cooling mechanism is installed in the processing cylinder 302.

[0039] The cleaned quartz sand is added into the rotating chamber 4 through the feed frame 401. At the same time, the drive motor 101 is started, which drives the rotating frame 301 to rotate. The rotating cylinder 3002 on the rotating frame 301 rotates accordingly. During the rotation of the rotating frame 301, the rotating chamber 4 is driven to rotate through the processing cylinder 302. The fixed top plate 402 and the feed frame 401 on the rotating chamber 4 do not rotate. During the rotation of the rotating chamber 4, the cleaned quartz sand is evenly added into the rotating chamber 4 through the feed frame 401. Since the dispersing frame 3004 is fixed to the fixed top plate 402, the dispersing frame 3004 does not rotate. During the rotation of the rotating chamber 4, the dispersing frame 3004 will disperse the quartz sand in the rotating chamber 4. During the rotation of the rotating chamber 4, the material will be pushed into the drying mechanism. The drying mechanism dries the quartz sand. After drying, the quartz sand will fall into the cooling mechanism. After the quartz sand in the cooling mechanism is cooled to a certain temperature, the cooling mechanism will discharge the quartz sand outward.

The heating component of the drying mechanism is existing technology, which is installed in the inner wall of the processing cylinder 302 and located above the lifting receiving plate 3031. The fixed base plate 303 is fixedly connected inside the processing cylinder 302, and a discharge hole is opened on the fixed base plate 303. A feeding hole is also provided at the corresponding position on the lifting receiving plate 3031, and a baffle extends downward from the feeding hole of the lifting receiving plate 3031. When the lifting receiving plate 3031 rises along the fixed base plate 303, the baffle extending downward from the lifting receiving plate 3031 will prevent the quartz sand from getting stuck between the lifting baffle and the fixed base plate 303. The lifting receiving plate 3031 is slidably connected inside the fixed base plate 303, and a lifting spring 3036 is provided between the lifting receiving plate 3031 and the fixed base plate 303. The lowering receiving plate 3031 is used to receive the quartz sand to be dried. As the weight of the quartz sand on the lowering receiving plate 3031 increases, the lowering receiving plate 3031 will be pressed into the fixed base plate 303 and compress the lifting spring 3036. The agitator 305 is rotatably connected inside the fixed base plate 303. An internal gear ring 403 is fixedly connected to the bottom of the fixed top plate 402.

The rotating rod 405 rotates under the action of the rotating gear 404 and the internal gear ring 403. The rotating rod 405 is fixedly connected to the stirring frame 305. The automatic discharge component is installed in the processing cylinder 302. The automatic discharge component can automatically discharge the dried quartz sand downwards. The feeding component is installed in the processing cylinder 302 and the rotating chamber 4.

The rotating baffle 307 passes through the lifting receiving plate 3031 and is rotatably connected. The rotating baffle 307 is used to block the discharge hole on the fixed base plate 303. A protrusion is fixed inside the rotating baffle 307. The protrusion inside the rotating baffle 307 is located in the arc-shaped slide rail 3061 on the lifting frame 306. During the up and down sliding process of the lifting frame 306, the rotating baffle 307 is driven to rotate under the action of the arc-shaped slide rail 3061 and the protrusion.

The shielding inclined plate 3037 is rotatably connected to the lifting receiving plate 3031, and the shielding inclined plate 3037 rotates with the rotating stop frame 307. A sliding unlocking rod 304 is slidably connected to the outside of the processing cylinder 302. 4 is fixedly connected to the lifting frame 306. A fixing plate 4011 is fixedly connected to the bottom of the feeding frame 401. A connecting block 406 is fixedly connected inside the rotating chamber 4. A sliding block 4061 is slidably connected inside the connecting block 406. The sliding block 4061 is U-shaped, and the end of the sliding block 4061 facing the L-shaped rod 4071 and the sliding unlocking rod 304 is inclined. A locking spring 4062 is provided between the sliding block 4061 and the connecting block 406. The two ends of the locking spring 4062 are fixed to the sliding block 4061 and the connecting block 406 respectively. A lifting stop is slidably connected to the rotating rod 405. A material block 407, a lifting baffle block 407, and a stirring frame 305 are provided with a baffle spring 408. An L-shaped rod 4071 is fixedly connected to the lifting baffle block 407. The L-shaped rod 4071 is slidably connected to the connecting block 406. A groove is provided on the L-shaped rod 4071, and a sliding block 4061 can be locked in the groove on the L-shaped rod 4071.

The second downward pressure spring 4073 is sleeved on the outside of the sliding pressure rod 4072. The two ends of the downward pressure spring 4073 are fixed to the L-shaped rod 4071 and the sliding pressure rod 4072 respectively. When the rotating chamber 4 rotates, the sliding pressure rod 4072 will slide downward under the action of the fixed pressure plate 4011. When the sliding block 4061 disengages from the L-shaped rod 4071, the sliding pressure rod 4072 will push the L-shaped rod 4071 and the lifting stop block 407 downward through the second downward pressure spring 4073. A connecting baffle 4074 is fixed on the L-shaped rod 4071. The connecting baffle 4074 is used to close the slide of the connecting block 406 when the L-shaped rod 4071 descends.

[0043] After the quartz sand enters the rotating chamber 4, since there is no quartz sand in the processing cylinder 302 at this time, the lifting spring 3036 lifts the lifting receiving plate 3031 upwards, and the connecting slide plate 3032 rises accordingly. The first downward spring 3033 between the connecting slide plate 3032 and the lifting frame 306 has not yet been compressed. At this time, the connecting slide plate 3032 and the fixed plate 3034 are both at their highest positions, and the limit block 3035 is located in the middle position of the inclined sliding groove on the fixed plate 3034. The limit block 3035 is not inserted into the slot on the guide rod 3021. At this time, the supporting spring 3022 pushes the lifting frame 306 and the sliding unlocking rod 304 to rise to their highest positions. As the rotating frame 301, the processing cylinder 302 and the rotating chamber 4 continue to rotate, when the sliding rod 4071... When the moving pressure rod 4072 rotates to the fixed pressure plate 4011, the fixed pressure plate 4011 will push the sliding pressure rod 4072 downward. Since the spring force of the baffle spring 408 is less than the spring force of the first pressing spring 3033, and the sliding unlocking rod 304 is at its highest point, the sliding unlocking rod 304 pushes the sliding block 4061 into the connecting block 406. During the descent of the sliding pressure rod 4072, it will push the lifting baffle block 407 and the connecting baffle plate 4074 downward via the L-shaped rod 4071. The baffle spring 408 is compressed, and the descent of the lifting baffle block 407 will open the channel between the rotating chamber 4 and the processing cylinder 302, allowing the quartz sand in the rotating chamber 4 to enter the processing cylinder 302. Furthermore, during the descent of the L-shaped rod 4071... Pushing the sliding unlocking lever 304, lifting frame 306, and limit block 3035 downwards compresses the support spring 3022. During the descent of the lifting frame 306, the limit block 3035 continues to slide away from the guide rod 3021 along the inclined groove on the fixed plate 3034. When the lifting frame 306 descends, it drives the rotating baffle 307 to rotate under the action of the arc-shaped slide rail 3061. The rotating baffle 307 will rotate to the bottom of the discharge hole on the fixed base plate 303 and block it. As the quartz sand continuously falls into the lifting receiving plate 3031 in the processing cylinder 302, the lifting receiving plate 3031 slides downwards along the fixed base plate 303 under the influence of the gravity of the quartz sand, compressing the support spring 3036. The connecting slide plate 3032 then descends and gradually... When the first compression spring 3033 is compressed, and the sliding pressure rod 4072 has completely passed through the fixed pressure plate 4011, the bottom surface of the lifting receiving plate 3031 just descends to be in contact with the top surface of the fixed base plate 303. At this time, the elastic force of the first compression spring 3033 is greater than the elastic force of the supporting spring 3022. During the descent of the connecting slide plate 3032, the fixed plate 3034 descends accordingly and pushes the limiting block 3035 to slide along the lifting frame 306 towards the guide rod 3021. When the bottom surface of the lifting receiving plate 3031 just descends to be in contact with the top surface of the fixed base plate 303, the limiting block 3035 just slides into the slot on the guide rod 3021. At this time, the sliding pressure rod 4072 disengages from the fixed pressure plate 4011 and is pushed by the supporting spring 3022.The lifting stop block 407 and its upper device will slide upward along the rotating rod 405 to reset and close the outlet of the rotating chamber 4. When the lifting stop block 407 rises to its highest position, the groove on the L-shaped rod 4071 is just aligned with the top of the sliding block 4061. Under the push of the locking spring 4062, the sliding block 4061 will be locked into the groove on the L-shaped rod 4071. At this time, enough quartz sand has been added into the processing cylinder 302. As the processing cylinder 302 continues to rotate, the sliding unlocking rod 304 cannot rise to reset because it is restricted by the limiting block 3035. When the sliding pressure rod 4072 passes the fixed pressure plate 4011 again, the L-shaped rod 4071 is limited by the sliding block 4061, and the sliding pressure rod 4072... The sliding rod 4072 is pushed down along the L-shaped rod 4071 and compresses the first downward pressure spring 3033. After passing the fixed pressure plate 4011, the first downward pressure spring 3033 pushes the sliding rod 4072 up to reset. During the rotation of the processing cylinder 302, the drying component inside the processing cylinder 302 heats the internal air to dry the quartz sand on the lifting receiving plate 3031. During the drying process, the rotating chamber 4 rotates continuously, and the rotating gear 404 on the rotating rod 405 rotates under the action of the internal gear ring 403. The rotating rod 405 also drives the stirring frame 305 to rotate. When the stirring frame 305 rotates, it can stir the quartz sand on the lifting receiving plate 3031 to improve the drying efficiency. As the moisture content of the quartz sand decreases, the weight of the quartz sand on the lifting receiving plate 3031 decreases. The lifting spring 3036 pushes the lifting receiving plate 3031 upward, and the connecting slide plate 3032 and the fixing plate 30314 rise accordingly. The first pressing spring 3033 gradually returns to its original position. During the rise of the fixing plate 3034, the limiting block 3035 will gradually slide out of the slot on the guide rod 3021. When the limiting block 3035 is completely disengaged from the slot on the guide rod 3021, the quartz sand on the lifting receiving plate 3031 is just dried. At this time, under the push of the supporting spring 3022, the lifting frame 306 will slide upward along the guide rod 3021 to reset, and at the same time, the arc-shaped slide 3... Under the action of 061, the rotating baffle 307 rotates to open the discharge hole on the fixed base plate 303. The top surfaces of both the fixed base plate 303 and the lifting receiving plate 3031 are inclined towards the discharge hole. The dried quartz sand on the lifting receiving plate 3031 passes through the discharge hole and falls into the cooling mechanism. During the rotation of the rotating baffle 307, the blocking inclined plate 3037 rotates accordingly, covering the rotation trajectory of the rotating baffle 307 to prevent the quartz sand from passing through. After the quartz sand has completely fallen out, the sliding pressure rod 4072, when passing the fixed pressure plate 4011, causes the quartz sand in the rotating chamber 4 to enter the processing cylinder 302. The above process is then repeated to dry the quartz sand.

[0044] like Figure 9 , Figure 12 and Figure 13As shown, the cooling mechanism includes a fixed lower pressure plate 3001, an exhaust fan 3003, a receiving baffle 5, a lifting and positioning frame 501, a conical stop 502, a support spring 504, an L-shaped pressure rod 505, a third lower pressure spring 506, and a limiting assembly. The fixed lower pressure plate 3001 is fixedly connected inside the processing cylinder 302. The exhaust fan 3003 is rotatably connected to the rotating frame 301 and is located inside the rotating cylinder 3002. The receiving baffle 5 is fixedly connected inside the processing cylinder 302. The lifting and positioning frame 501 is slidably connected to the stirring frame 305. A conical stop 502 is fixedly connected to the lifting and positioning frame 501 and is located at the discharge hole on the receiving baffle 5. One end of the positioning frame 501 passes through and is slidably connected to the processing cylinder 302. A support spring 504 is provided between the lifting positioning frame 501 and the processing cylinder 302. The two ends of the support spring 504 are fixed to the lifting positioning frame 501 and the processing cylinder 302, respectively. An L-shaped pressure rod 505 is slidably connected to the lifting positioning frame 501. The L-shaped pressure rod 505 is located outside the processing cylinder 302. A third downward pressure spring 506 is provided between the L-shaped pressure rod 505 and the lifting positioning frame 501. The two ends of the third downward pressure spring 506 are fixed to the L-shaped pressure rod 505 and the lifting positioning frame 501, respectively. A limiting component is installed inside the lifting positioning frame 501. The limiting component is used to limit the position of the lifting positioning frame 501.

[0045] like Figure 12 and Figure 13 As shown, the limiting assembly includes a temperature regulating push block 5011, a sliding rod 5012, a return spring 5013, a wedge block 5014, a top support spring 5015, a fixing block 5016, a sliding block 503, and a reset spring 5031. The temperature regulating push block 5011 is installed inside the lifting and positioning frame 501. The temperature regulating push block 5011 can increase or decrease according to temperature changes. The sliding rod 5012 is slidably connected inside the lifting and positioning frame 501. A return spring 5013 is provided between the sliding rod 5012 and the lifting and positioning frame 501. The two ends of the return spring 5013 are respectively fixed to the lifting and positioning frame 501 and the sliding rod 5012. A wedge block 5014 is slidably connected to the end of the sliding rod 5012. The wedge block 5014... The part has a groove, and the two ends of the groove at the top of the wedge block 5014 are at different heights. A top support spring 5015 is provided between the wedge block 5014 and the sliding rod 5012. The two ends of the top support spring 5015 are fixed to the wedge block 5014 and the sliding rod 5012 respectively. A fixing block 5016 is fixedly connected inside the lifting and positioning frame 501. The fixing block 5016 can push the wedge block 5014 into the sliding rod 5012. A sliding block 503 is slidably connected inside the lifting and positioning frame 501. The sliding block 503 can be inserted into the groove on the inner wall of the processing cylinder 302. A return spring 5031 is provided between the sliding block 503 and the lifting and positioning frame 501. The two ends of the return spring 5031 are fixed to the sliding block 503 and the lifting and positioning frame 501 respectively.

[0046] After the quartz sand is dried, it falls onto the receiving baffle 5. The temperature above the receiving baffle 5 rises rapidly, causing the temperature regulating push block 5011 inside the lifting and positioning frame 501 to expand due to the heat. Simultaneously, this pushes the sliding rod 5012 towards the sliding block 503, compressing the return spring 5013. The wedge block 5014 moves accordingly. When the wedge block 5014 contacts the sliding block 503, the sliding block 503 pushes the wedge block 5014 downwards, compressing the top support spring 5015. After the wedge block 5014 passes through the cylindrical through hole on the sliding block 503, the top support spring 5015 pushes the wedge block 5014 upwards to reset. At this point, the groove at the top of the wedge block 5014 is engaged with the sliding block 503, and the exhaust fan... During the rotation of cylinder 3003, an upward airflow is blown out. The processing cylinder 302 has two openings: one is an exhaust port connected to the rotating cylinder 3002, and the other is an air inlet. Hot air above the receiving baffle 5 flows into the rotating cylinder 3002 along the exhaust port on the side of the processing cylinder 302. Subsequently, external cold air enters the processing cylinder 302 through the air inlet to replace the air inside and rapidly cool the dried quartz sand. During the cooling process, the stirring frame 305 agitates the quartz sand on the receiving baffle 5 to improve cooling efficiency. As the temperature of the quartz sand on the receiving baffle 5 continuously decreases, the temperature regulating push block 5011 gradually shrinks. Under the push of the return spring 5013, the sliding rod 5012 slides back to its original position along the lifting and positioning frame 501. During the sliding and resetting process, the sliding rod 5012 pulls the sliding block 503 through the wedge block 5014 and compresses the return spring 5031, causing the sliding block 503 to disengage from the processing cylinder 302. Subsequently, when the processing cylinder 302 rotates with the rotating frame 301 to the fixed lower pressure plate 3001, the L-shaped pressure rod 505 is pushed down by the fixed lower pressure plate 3001. During the descent of the L-shaped pressure rod 505, the lifting and positioning frame 501 is pushed down along the stirring frame 305 by the third lower pressure spring 506, which simultaneously drives the conical stop block 502 to descend, receiving the cooled quartz sand on the receiving baffle 5. The material falls down and exits from the bottom outlet of the processing cylinder 302. After the L-shaped pressure rod 505 disengages from the fixed lower pressure plate 3001, the lifting clamping frame 501 slides upward and resets under the push of the support spring 504. The conical stop block 502 rises and resets accordingly, blocking the through hole on the receiving baffle 5. At the same time, the temperature regulating push block 5011 returns to its initial size, and the wedge block 5014 contacts the fixed pressure block 5016. Under the push of the fixed pressure block 5016, the wedge block 5014 slides down into the sliding rod 5012 and disengages from the sliding block 503. The reset spring 5031 pushes the sliding block 503 to slide and reset along the lifting clamping frame 501 and re-clamp into the groove on the inner wall of the processing cylinder 302.

[0047] Example 3: Based on Example 2, such as Figures 1-3As shown, it also includes a pretreatment mechanism for pre-drying the washed quartz sand. The pretreatment mechanism includes a pretreatment box 2, a discharge port 2001, a feeding frame 201, a discharge inclined plate 202, and a lifting assembly. The pretreatment box 2 is fixedly connected to the support base 1. Heating wires are installed inside the four side walls of the pretreatment box 2 to heat the air inside the pretreatment box 2. The discharge port 2001 is opened at one end of the pretreatment box 2 near the feeding frame 401. The feeding frame 401 is fixedly connected to the pretreatment box 2. The feeding frame 201 is fixedly connected to the top of the pretreatment box 2. The washed quartz sand passes through the feeding frame. 201 is added into the pretreatment box 2. There are two feeding inclined plates 202 fixed inside the pretreatment box 2. Quartz sand slides along the feeding inclined plates 202 and is pre-dried. There is a certain distance between the end of the lower feeding inclined plate 202 and the discharge port 2001. Only when the speed at which the quartz sand falls along the surface of the lower feeding inclined plate 202 reaches a certain value can the corresponding quartz sand pass through the discharge port 2001 and fall outward. The lifting component is installed in the pretreatment box 2. The lifting component is used to push the quartz sand with excessive moisture content upward and continue to pre-dry it.

[0048] like Figure 2 and Figure 3 As shown, the lifting assembly includes a recovery frame 203, a lifting cylinder 204, a spiral lifting blade 205, and a rotating gear frame 2051. The recovery frame 203 is fixedly connected inside the pretreatment box 2, and the lifting cylinder 204 is fixedly connected outside the pretreatment box 2. The bottom outlet of the recovery frame 203 is connected to the lifting cylinder 204. The spiral lifting blade 205 is rotatably connected inside the lifting cylinder 204. The rotating gear frame 2051 is rotatably connected to the support base 1. The rotating gear frame 2051 meshes with the external teeth on the rotating frame 301. The rotating gear frame 2051 is fixedly connected to the spiral lifting blade 205.

[0049] After washing, the quartz sand is first poured into the feeding frame 201 and then into the pretreatment box 2. At this time, the heating wire inside the pretreatment box 2 is activated, heating the air inside. The quartz sand entering the pretreatment box 2 is pre-dried by the high-temperature gas. The washed quartz sand has a high moisture content, and most of it clumps together. The contact surface between the clumps and the feeding inclined plate 202 is irregular, and the agglomeration of the quartz sand is enhanced, resulting in greater friction between the agglomerated quartz sand and the feeding inclined plate 202. The quartz sand slides slowly down the feeding inclined plate 202. After entering the pretreatment box 2, the high temperature inside the pretreatment box 2 performs preliminary drying on the quartz sand. During the pre-drying process, the moisture content of the quartz sand gradually decreases, and the agglomerated quartz sand gradually disperses. The adhesion between the quartz sand and the feeding inclined plate 202 weakens, and the friction between the quartz sand and the feeding inclined plate 202 gradually decreases. That is, as the moisture content of the quartz sand gradually decreases, the speed of the quartz sand continuously increases. After the quartz sand passes through two feeding inclined plates 202, the quartz sand with a moisture content reduced to the standard for drying will enter the feed frame 401 from the side outlet 2001 of the pretreatment box 2, and finally enter the rotating chamber 4. The quartz sand that does not meet the standard will fall into the recycling frame 203, and finally slide along the recycling frame 203 into the lifting cylinder 204. When the rotating frame 301 rotates, it drives the spiral lifting blades 205 to rotate through the rotating gear frame 2051. The quartz sand entering the lifting cylinder 204 is conveyed upward to the highest point by the spiral lifting blades 205 and re-enters the top of the pretreatment box 2 to reduce the moisture content in the washed quartz sand.

[0050] like Figure 3 and Figure 4 As shown, it also includes a cleaning mechanism for cleaning the quartz sand adhering to the feeding inclined plate 202. The cleaning mechanism includes a reciprocating screw 206, a belt drive component 207, a sliding guide frame 208, and a sliding scraper 209. The reciprocating screw 206 is rotatably connected to the outside of the pretreatment box 2. The reciprocating screw 206 is connected to the spiral lifting blade 205 through the belt drive component 207. The spiral lifting blade 205 drives the reciprocating screw 206 to rotate through the belt drive component 207. The sliding guide frame 208 is slidably connected to the outside of the pretreatment box 2. The sliding guide frame 208 is threadedly connected to the reciprocating screw 206. The reciprocating screw 206 can drive the sliding guide frame 208 to move up and down. A slotted sliding hole is opened in the sliding guide frame 208. The sliding scraper 209 is slidably connected in the slotted sliding hole in the sliding guide frame 208. The sliding scraper 209 is in contact with the feeding inclined plate 202.

[0051] The washed quartz sand has a high water content. As the quartz sand slides downward, it may adhere to the feeding inclined plate 202. When the spiral lifting blade 205 rotates, it will drive the reciprocating screw 206 to rotate through the belt drive component 207. When the reciprocating screw 206 rotates, it will drive the sliding guide frame 208 to slide up and down. When the sliding guide frame 208 moves up and down, it will drive the sliding scraper 209 to slide along the feeding inclined plate 202 to scrape off the quartz sand adhering to the feeding inclined plate 202.

[0052] like Figure 6 and Figure 9 As shown, it also includes a discharge mechanism that discharges dust to the pretreatment box 2 for recycling. The discharge mechanism includes a filter plate 3023, a fixed frame 6, and a discharge pipe 601. The treatment cylinder 302 has an exhaust port on the side near the rotating cylinder 3002. The filter plate 3023 is fixedly connected to the exhaust port on the treatment cylinder 302. The top of the disintegration frame 3004 passes through the fixed top plate 402 and is fixedly connected to it. The fixed frame 6 is fixedly connected to the disintegration frame 3004. The discharge pipe 601 is fixedly connected to the fixed frame 6. The discharge pipe 601 is fixedly connected to the feeding frame 201. The fixed frame 6 and the feeding frame 201 are connected through the discharge pipe 601. A filter screen is fixedly connected to one end of the discharge pipe 601 that is connected to the feeding frame 201.

[0053] As the exhaust fan 3003 rotates and discharges the gas inside the treatment cylinder 302, the high-temperature gas between the fixed base plate 303 and the receiving baffle 5 is blown outward. The dust contained in the high-temperature gas is blocked by the filter plate 3023 and cannot pass through the exhaust port on the side of the treatment cylinder 302. The high-temperature gas finally passes through the fixed frame 6 and the discharge pipe 601 and is discharged into the pretreatment box 2. The high-temperature gas comes into contact with the cleaned quartz sand and heats the quartz sand to achieve the function of exhaust gas temperature recovery and utilization.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
