Abstract
Description
Technical Field
[0001] This utility model belongs to the field of quartz sand drying technology, specifically relating to a novel quartz sand drying device. Background Technology
[0002] Quartz sand drying refers to the industrial process of removing moisture from quartz sand through specific techniques, aiming to improve its purity, stability, and performance. As a non-metallic mineral raw material, quartz sand often contains high moisture content in its natural state or after mining, requiring drying to reduce its moisture content to 0.5%-5% to meet industrial requirements. This process typically employs the principle of thermal evaporation: wet quartz sand enters the drying equipment through a feeding device, where heat and mass transfer evaporate the moisture, and finally, dried sand particles are output through a discharge device.
[0003] For example, a quartz sand drying device with announcement number CN221549286U uses hot air entering the distribution pipe and then being evenly blown to different locations within the drying chamber through the drying pipe. This allows for thorough drying of the quartz sand at different locations within the chamber. Adjusting the tilt angle of the screen allows the quartz sand to slide on the screen, turning it over during the drying process and minimizing dead zones, thus promoting uniform drying. However, this technology uses heating wires to heat heating tubes, which in turn heat the air, ultimately drying the moist quartz sand. This indirect heating method results in heat loss with each heat transfer, leading to significant energy waste. Furthermore, while the quartz sand is heated with hot air, there is no dedicated exhaust system for the heated, moist air, causing moisture to flow back into the sand, reducing drying efficiency and resulting in unnecessary waste of time and energy. Utility Model Content

The rising protective cylinder 5; two drying brackets 2 are respectively installed on the upper wall of the drying device base 1; the container wall 3 is movably installed between the two drying brackets 2 via a shaft, and the container wall 3 and the two drying brackets 2 are relatively fixed by bolts; the container heating seat 4 is installed on the lower wall of the container wall 3; the rising protective cylinder 5 is installed inside the container wall 3 via four connecting columns; the upper wall of the container wall 3 is provided with a feed inlet 17, and the feed inlet 17 of the container wall 3 is movably installed with a sealing cover 18 via a hinge; the side wall of the container wall 3 is provided with a handle 19, and the side wall of the container wall 3 is provided with an extension feed port 20.
[0019] As a preferred embodiment, the rising and tilting structure further includes: a rising movable shaft 6, a rising spiral blade 7, and a driven gear 8; the rising movable shaft 6 is movably mounted inside the container wall 3 via bearings, and the rising movable shaft 6 is mounted on the upper wall of the container heating seat 4 via a movable seat; the rising spiral blade 7 is fixedly mounted outside the rising movable shaft 6, and the rising spiral blade 7 is located inside the rising protective cylinder 5; the driven gear 8 is mounted on the upper wall of the rising movable shaft 6.
[0020] As a preferred embodiment, the tumbling power structure further includes: a tumbling power motor 9 and a drive gear 10; the tumbling power motor 9 is installed on the upper wall surface of the container wall 3, the drive gear 10 is installed on the drive end of the tumbling power motor 9, and the drive gear 10 meshes with the driven gear 8.
[0021] As a preferred embodiment, the exhaust structure further includes: an exhaust pipe 11, an exhaust pump 12, and an exhaust check valve 13; the exhaust pipe 11 is installed on the upper wall of the container wall 3, the exhaust pump 12 is installed outside the exhaust pipe 11, and the exhaust check valve 13 is installed outside the exhaust pipe 11.
[0022] As a preferred embodiment, the intake structure further includes: an intake pipe 14, an intake one-way valve 15, and an intake desiccant container 16; the intake pipe 14 is installed on the side wall of the container wall 3, the intake desiccant container 16 is installed outside the intake pipe 14, and the intake one-way valve 15 is installed outside the intake pipe 14.
[0023] Working principle: Before using this device, an external AC power supply needs to be connected to the device to provide energy for the electrical appliances in the device, and a matching controller needs to be connected to the device to provide control and working logic for the electrical appliances. Then, the operator places the calcium chloride desiccant granules into the air inlet desiccant container 16, which completes the preparation work of the device.
[0024] The operator first opens the sealing cover 18 by folding the hinge, exposing the feed inlet 17. The operator then injects the previously processed damp quartz sand through the feed inlet 17 into the container wall 3 and the container heating base 4. The container heating base 4 then starts operating, heating its interior. Simultaneously, the rotating motor 9 begins to rotate, driving the drive gear 10. Through the meshing of the gears, the drive gear 8 rotates, which in turn drives the rising shaft 6 and the rising spiral blade 7. This causes the quartz sand inside the container heating base 4 to move upwards along the rising spiral blade 7 and then upwards along the inside of the rising protective cylinder 5 until it reaches the top of the rising protective cylinder 5. The quartz sand then falls back into the container heating base 4. As heating continues, the moisture in the quartz sand evaporates. The exhaust pump 12 starts working, heating the container wall 3 and the container heating seat 4 to generate a large amount of air mixed with water vapor. The humid air is discharged into the atmosphere through the exhaust one-way valve 13 and the exhaust pipe 11. At this time, a relative vacuum is created inside the container wall 3 and the container heating seat 4. The air in the atmosphere passes through the intake one-way valve 15 and the intake desiccant container 16, and enters the interior of the container wall 3 and the container heating seat 4 through the intake pipe 14. When the moisture in the atmospheric air passes through the intake desiccant container 16, it is adsorbed by the calcium chloride desiccant particles, thereby gradually reducing the humidity inside the container wall 3 and the container heating seat 4. A humidity sensor is installed inside. When the humidity drops to a preset threshold, the container heating seat 4 stops working, while the turning motor 9 continues to work. After the quartz sand cools down, both the turning motor 9 and the exhaust pump 12 stop working.
[0025] After the heating and drying are completed, the operator removes the bolts used to connect the container wall 3 and the two drying supports 2, and opens the sealing cover 18. The operator rotates the container wall 3 by the handle 19. The container wall 3 and the container heating seat 4 rotate gradually until the quartz sand inside the container is discharged through the extension port 20. At this time, the drying of quartz sand is completed.
