Description

Technical Field

[0001] This invention relates to the field of quartz sand particle processing technology, and in particular to a high-temperature drying and ultra-low temperature cold explosion device and its usage method. Background Technology

[0002] Quartz sand, as an important industrial raw material, is widely used in glass, ceramics, casting, electronics, and photovoltaic industries. During its production and processing, it often requires high-temperature drying to remove moisture and volatile impurities, followed by rapid cooling to improve its particle structure, purity, and physical properties.

[0003] When quartz sand particles are dried at high temperature, the gas-liquid inclusions are in an open state, making it easy to remove moisture and impurities. However, existing processes involve allowing the quartz sand particles to cool naturally after high-temperature drying. In the naturally cooling environment, moisture and other impurities can re-enter and reform inclusions, thus affecting the purity of the product.

[0004] Therefore, there is an urgent need to develop a compact quartz sand processing device that can achieve high-temperature drying and rapid ultra-low temperature cooling in order to improve product quality and meet the needs of modern production. Summary of the Invention

[0005] The purpose of this invention is to provide a high-temperature drying and ultra-low temperature cooling device and its usage method. Quartz sand materials can be rapidly and continuously processed by high-temperature drying and ultra-low temperature cooling in a single device. The process flow is highly integrated, which greatly shortens the processing cycle and improves production efficiency.

[0006] To achieve the above objectives, the present invention provides a high-temperature drying and ultra-low temperature cooling explosion device, comprising a vacuum feeding mechanism, two boxes, a tube, a stainless steel tube, and a rotation drive mechanism. The tube and the stainless steel tube are respectively embedded inside one of the boxes, and the right end of the tube is connected to and fixed together with the left end of the stainless steel tube.

[0007] Preferably, the stainless steel pipe has a double-layer pipe structure, with a liquid nitrogen containment cavity provided between the inner and outer rings of the double-layer pipe. A liquid nitrogen inlet is provided at the top of the closed end on the left side of the stainless steel pipe, and a liquid nitrogen outlet is provided at the bottom of the closed end on the right side of the stainless steel pipe. The liquid nitrogen inlet and outlet are connected to the liquid nitrogen containment cavity. A material outlet is also provided at the closed end on the right side of the stainless steel pipe, and material is conveyed in the space of the inner ring of the stainless steel pipe.

[0008] Preferably, the liquid nitrogen containment chamber is filled with liquid nitrogen at -180°.

[0009] Preferably, the outer surface of the tube located inside the box is provided with an electromagnetic heating structure.

[0010] Preferably, the rotation drive mechanism includes a motor, gear one, gear two, gear three, and gear four. The motor is fixed to the wall of the housing. The transmission shaft passes through the two housings and is rotatably connected to the two housings. Gear one and gear three are fixed on the transmission shaft. Gear one and gear two are both located outside the housing. Gear two is fixed on the outer surface of the left closed end of the tube. Gear one and gear two mesh and drive each other. Gears three and four are both located outside the housing. Gear four is fixed to the outer surface of the closed end of the stainless steel tube on the right. Gears three and four mesh and drive each other.

[0011] Preferably, the tube body is rotatably connected to the wall of the housing via a bearing, and the stainless steel tube is rotatably connected to another housing via a bearing, with the tube body and the stainless steel tube rotating in the same direction.

[0012] Preferably, the bottom of the two boxes is fixed with a support, and the bottom of the support is provided with a base one and a base two. The top of the base one is hinged to the bottom of the support, and the top of the base two is provided with an electric telescopic rod. The movable end of the electric telescopic rod is hinged to the bottom of the support. By extending the movable end of the electric telescopic rod of the base two, the left side of the left box is higher than the right side of the right box, so that the quartz sand particles are conveyed inclined downward.

[0013] Preferably, the vacuum feeding mechanism includes a hopper, a vacuum pump, a conveying hopper, and a control valve. The hopper is connected to the conveying hopper via a pipe, and a control valve is installed between the conveying hopper and the hopper.

The quartz sand particle inlet is located at the center of the closed end on the left side of the pipe body.

[0014] Preferably, the inner surface of each of the boxes is provided with thermal insulation cotton.

[0015] A method for using a high-temperature drying and ultra-low temperature cold explosion device includes the following steps: Step 1: Control the rotation drive mechanism through the controller to drive the tube body and stainless steel tube to rotate synchronously, and then fill the liquid nitrogen containing chamber with liquid nitrogen; Step 2: Control the operation of the vacuum feeding mechanism through the controller, and the vacuum feeding mechanism will transport the material to the quartz sand particle inlet; Step 3: As the pipe body and stainless steel pipe are inclined downward along the material conveying direction, and under the action of the rotation drive mechanism, the material is conveyed inclined downward. The material is first heated in the pipe body, then rapidly cooled in the stainless steel pipe, and finally output from the material outlet.

[0016] The advantages and positive effects of the high-temperature drying and ultra-low temperature cold explosion device described in this invention are: 1. When quartz sand particles are dried at high temperatures, the gas-liquid inclusions are in an open state, making it easier to remove moisture and impurities. However, existing processes involve natural cooling of the quartz sand particles after high-temperature drying. In the natural cooling environment, moisture and other impurities can re-enter and reform inclusions, affecting product purity. This invention allows for rapid and continuous processing of quartz sand material, sequentially undergoing high-temperature drying and ultra-low-temperature cooling within a single unit. After high-temperature drying, the quartz sand particles are rapidly cooled while the gas-liquid inclusions are open, quickly removing moisture and impurities, thus improving production efficiency and product purity.

[0017] 2. By connecting and integrating a tube with electromagnetic heating function with a double-layer stainless steel tube with liquid nitrogen cooling function, and under the synchronous drive of the rotation drive mechanism, the material can be rapidly and continuously processed by high temperature drying and ultra-low temperature cooling in a single unit. The process flow is highly integrated, which greatly shortens the processing cycle and improves production efficiency.

[0018] 3. The pipe body and stainless steel pipe rotate synchronously in the same direction under the drive mechanism, so that the material is constantly turned over during the conveying process, effectively avoiding material accumulation. Combined with the downward inclined arrangement, the material is conveyed smoothly under the assistance of gravity, ensuring that it is heated evenly in the heating section and comes into rapid and even contact with the cold source in the cooling section, thereby significantly improving the consistency and stability of product performance.

Both ends of the tube 3 are closed ends, and the closed ends of the tube 3 extend to the outside of the box 2. Both ends of the stainless steel tube 7 are closed ends, and the closed ends of the stainless steel tube 7 extend to the outside of the other box 2. The rotation drive mechanism 5 is provided on the outer surface of the left closed end of the tube 3 and the right closed end of the stainless steel tube 7.

[0026] The stainless steel pipe 7 has a double-layer pipe body 3 structure. A liquid nitrogen containing cavity 8 is provided between the inner and outer rings of the double-layer pipe body 3. A liquid nitrogen inlet 9 is opened at the top of the closed end on the left side of the stainless steel pipe 7, and a liquid nitrogen outlet 10 is opened at the bottom of the closed end on the right side of the stainless steel pipe 7.

A material outlet 11 is also provided at the closed end on the right side of the stainless steel pipe 7, and material is conveyed in the space of the inner ring of the stainless steel pipe 7.

[0027] The liquid nitrogen containment chamber 8 is filled with liquid nitrogen at -180°C, which can rapidly cool the materials conveyed in the stainless steel tube 7.

[0028] The outer surface of the portion of the tube body 3 located inside the box body 2 is equipped with an electromagnetic heating structure, which can heat the tube body 3 and thus heat the material conveyed by the tube body 3, thereby performing a drying operation on the material.

[0029] The rotation drive mechanism 5 includes a motor 501, gear 1 502, gear 2 503, gear 3 505, and gear 4 506. The motor 501 is fixed to the wall of the housing 2. The output shaft of the motor 501 is connected to a drive shaft 504. The drive shaft 504 passes through the two housings 2 and is rotatably connected to the two housings 2. Gear 1 502 and gear 3 505 are fixed on the drive shaft 504. Gear 1 502 and gear 2 503 are both located outside the housing 2. Gear 2 503 is fixed on the outer surface of the closed end on the left side of the tube 3. Gear 1 502 and gear 2 503 mesh and drive each other.

[0030] Gear 3 505 and gear 4 506 are both located outside the housing 2. Gear 4 506 is fixed on the outer surface of the closed end of the right end of the stainless steel tube 7. Gear 3 505 and gear 4 506 mesh and drive each other.

[0031] The pipe body 3 is rotatably connected to the wall of the box 2 via the bearing 4, and the stainless steel pipe 7 is rotatably connected to another box 2 via the bearing 4. The pipe body 3 and the stainless steel pipe 7 rotate in the same direction.

[0032] Specifically, the motor 501 of the rotation drive mechanism 5 controls the synchronous rotation of the tube body 3 and the stainless steel tube 7, which can turn over the materials conveyed in the tube body 3 and the stainless steel tube 7.

[0033] The bottom of the two boxes 2 is fixed with supports. The bottom of the supports is provided with base one and base two. The top of base one is hinged to the bottom of the support. The top of base two is provided with an electric telescopic rod. The movable end of the electric telescopic rod is hinged to the bottom of the support. By extending the movable end of the electric telescopic rod of base two, the left side of the left box 2 is higher than the right side of the right box 2, so that the quartz sand particles are conveyed downward at an incline.

[0034] The vacuum feeding mechanism 1 includes a hopper 101, a vacuum pump 103, a conveying chamber 102, and a control valve. The hopper 101 is connected to the conveying chamber 102 via a pipe.

The quartz sand particle inlet 6 is located at the center of the closed left end of the tank.

[0035] Specifically, during vacuum feeding, the controller closes the control valve 104 between the quartz sand particle inlet 6 and the conveying chamber 102, opens the control valve 104 between the hopper 101 and the conveying chamber 102, and starts the vacuum pump 103, so that the material in the hopper 101 is sucked into the conveying chamber 102. When the material in the conveying chamber 102 reaches a certain position, the vacuum pump 103 stops running. Then, the controller closes the control valve 104 between the hopper 101 and the conveying chamber 102, and opens the control valve between the quartz sand particle inlet 6 and the conveying chamber 102, so that the material is conveyed to the quartz sand particle inlet 6.

[0036] The inner surface of each box 2 is lined with insulation cotton. The insulation cotton serves to keep the temperature warm.

[0037] The present invention discloses a method for using a high-temperature drying and ultra-low temperature cold explosion device, comprising the following steps: Step 1: Control the rotation drive mechanism 5 through the controller to drive the tube body 3 and stainless steel tube 7 to rotate synchronously, and then fill the liquid nitrogen containing chamber 8 with liquid nitrogen.

[0038] Step 2: Control the operation of vacuum feeding mechanism 1 through the controller. Vacuum feeding mechanism 1 will transport the material to the quartz sand particle inlet 6.

[0039] Step 3: Since the pipe body 3 and the stainless steel pipe 7 are inclined downward along the material conveying direction, and under the action of the rotation drive mechanism 5, the material is conveyed inclined downward. The material is first heated in the pipe body 3, then rapidly cooled in the stainless steel pipe 7, and finally output from the material outlet 11.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them.
