Abstract
Description
Technical Field
[0001] This utility model relates to the field of high-purity quartz sand production technology, and in particular to a drying equipment for high-purity quartz sand production. Background Technology
[0002] Quartz sand is quartz particles produced by crushing and processing quartz stone. It is milky white or colorless and translucent. Quartz sand is an important industrial mineral raw material, widely used in glass, casting, ceramics and fireproof materials, ferrosilicon smelting, metallurgical solvents, metallurgy, construction, chemicals, plastics, rubber, abrasives, filter media, and other fields. Generally, high-purity quartz sand undergoes a series of processes during preparation, including crushing, pulverizing, magnetic separation, sieving, roasting, water crushing, flotation, deionized water washing, drying, and acid leaching. Drying equipment is used to treat high-purity quartz sand.
[0003] Chinese Patent Application Publication No. 202323596165.3 discloses a high-efficiency drying device for quartz sand, including a base and a trolley. A main body is fixedly connected to the middle of the upper surface of the base, and a rubber ring is fixedly connected to the periphery of the upper surface of the main body. The lower end of the inner wall of the main body has slots on both sides. Two electric telescopic rods are fixedly connected to the inner wall of the slots near the main body. A baffle is fixedly connected to the outer wall of the electric telescopic rods away from the main body. A top cover is fixedly connected to the upper surface of the main body.
[0004] Although the aforementioned drying equipment can dry high-purity quartz sand, the high-purity quartz sand tends to accumulate inside the equipment during use. Even with a stirring structure, the drying speed remains slow. Due to the accumulation of quartz sand, hot air cannot evenly contact each quartz sand particle, resulting in low heat transfer efficiency. While the stirring structure can agitate the quartz sand to some extent, it cannot effectively break up the accumulation, thus limiting the contact area between the quartz sand and the hot air, which in turn slows down the drying speed of the high-purity quartz sand. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a drying device for high-purity quartz sand production, which solves the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A drying device for producing high-purity quartz sand includes a drying chamber. An elastic component is installed inside the drying chamber, and a frame is installed inside the drying chamber via the elastic component. An installation groove is opened on the front side of the frame, and an installation plate is inserted into the installation groove. A flat tray is fixedly installed on the top of the installation plate. A drive component is installed on the right side of the drying chamber, and a rotating shaft is installed on the right side of the drying chamber via the drive component. A transmission component is installed on the surface of the rotating shaft, and a rotating rod is installed on the surface of the rotating shaft via the transmission component. The rotating rod is rotatably connected to the drying chamber, and a cam is fixedly installed on the surface of the rotating rod. A heating rod is fixedly installed inside the drying chamber.
[0008] Preferably, the elastic component includes a support block disposed inside the drying chamber, a spring fixedly installed on the top of the support block, and the spring being fixedly connected to the frame.
[0009] Preferably, the drive assembly includes a fixed plate disposed on the right side of the drying chamber, a drive motor is fixedly mounted on the top of the fixed plate, the output end of the drive motor is fixedly connected to a rotating shaft, and the rotating shaft is rotatably connected to the fixed plate.
[0010] Preferably, the transmission assembly includes a first bevel gear disposed on the surface of the rotating shaft, a second bevel gear meshing on the surface of the first bevel gear, and the second bevel gear being fixedly connected to the rotating rod.
[0011] Preferably, the drying oven is provided with a door on the front side, and a handle is fixedly installed on the front side of the door.
[0012] Preferably, a support leg is fixedly installed at the bottom of the drying box, and an anti-slip pad is provided at the bottom end of the support leg.
[0013] Preferably, the mounting plate has a convex structure, and the mounting groove is adapted to the mounting plate.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This high-purity quartz sand drying equipment places a flat tray containing high-purity quartz sand into a drying chamber. Heating is then applied by heating rods, raising the internal temperature of the drying chamber and drying the high-purity quartz sand on the tray. Simultaneously, a drive assembly rotates the shaft, which in turn rotates the transmission assembly, causing the rotating rod and cam to rotate. The cam's rotation causes the frame to vibrate slightly up and down via the elastic assembly, resulting in slight vibration of the flat tray and the high-purity quartz sand within it. This effectively loosens the quartz sand particles, reducing accumulation and ensuring each particle is fully exposed to the hot air. This uniform heat contact significantly improves heat transfer efficiency, allowing the moisture in the quartz sand to evaporate more quickly, thus significantly shortening the drying time and increasing the drying speed.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Reference Figure 1-4A drying device for producing high-purity quartz sand includes a drying chamber 1. An elastic component is installed inside the drying chamber 1, and a frame 4 is installed inside the drying chamber 1 via the elastic component. An installation groove 5 is opened on the front side of the frame 4, and an installation plate 6 is inserted into the installation groove 5. The installation plate 6 has a convex structure, and the installation groove 5 and the installation plate 6 are adapted to each other, so that the installation plate 6 can only be pulled out from the front side of the installation groove 5 and cannot be removed from above the installation groove 5. A flat tray 7 is fixedly installed on the top of the installation plate 6. A drive assembly is located on the right side of the drying chamber 1, and a rotating shaft 10 is installed on the right side of the drying chamber 1 via the drive assembly. A transmission assembly is provided on the surface of the rotating shaft 10, and a rotating rod 13 is provided on the surface of the rotating shaft 10 via the transmission assembly. The rotating rod 13 is rotatably connected to the drying chamber 1, and a cam 14 is fixedly installed on the surface of the rotating rod 13. A heating rod 18 is fixedly installed inside the drying chamber 1. A door 15 is located on the front side of the drying chamber 1, and a handle 16 is fixedly installed on the front side of the door 15. Support legs 17 are fixedly installed at the bottom of the drying chamber 1. The bottom of leg 17 is equipped with an anti-slip pad to facilitate stable support for the drying chamber 1. In this high-purity quartz sand production drying equipment, after the flat tray 7 containing high-purity quartz sand is placed into the drying chamber 1, it is heated by heating rod 18, raising the internal temperature of the drying chamber 1 and thus drying the high-purity quartz sand on the flat tray 7. Simultaneously, the drive assembly rotates the rotating shaft 10, causing the transmission assembly to rotate, which in turn rotates the rotating rod 13 and the cam 14. The rotation of the cam 14 causes the frame 4 to vibrate slightly up and down via the elastic component, causing the flat tray 7 to vibrate slightly, and the high-purity quartz sand in the flat tray 7 to vibrate. This effectively loosens the quartz sand particles, reducing accumulation and ensuring that each quartz sand particle is fully exposed to the hot air. This uniform heat contact greatly improves heat transfer efficiency, allowing the moisture in the quartz sand to evaporate more quickly, thus significantly shortening the drying time and increasing the drying speed.
[0022] Specifically, the elastic component includes a support block 2 installed inside the drying oven 1. A spring 3 is fixedly installed on the top of the support block 2. The spring 3 is fixedly connected to the frame 4. The elastic component facilitates the elastic support of the frame 4. When the cam 14 rotates, the frame 4 can move up and down, thereby facilitating the frame 4 to vibrate slightly.
[0023] Specifically, the drive assembly includes a fixed plate 8 located on the right side of the drying chamber 1. A drive motor 9 is fixedly mounted on the top of the fixed plate 8. The output end of the drive motor 9 is fixedly connected to the rotating shaft 10. The rotating shaft 10 is rotatably connected to the fixed plate 8. The drive assembly facilitates the provision of driving force for the rotation of the rotating shaft 10. The transmission assembly includes a first bevel gear 11 disposed on the surface of the rotating shaft 10. A second bevel gear 12 is meshed on the surface of the first bevel gear 11. The second bevel gear 12 is fixedly connected to the rotating rod 13. The transmission assembly facilitates transmission when the rotating shaft 10 rotates, thereby facilitating the simultaneous rotation of the rotating rod 13. This allows the rotating rod 13 to be driven by the same drive source, reducing motor waste and thus saving energy.
[0024] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be any conventional known device, such as a computer, that can control the operation of the electrical components mentioned in the article.
[0025] In use: Open the door 15 using handle 16, insert the flat tray 7 containing high-purity quartz sand into the mounting slot 5 via mounting plate 6, and place the flat tray 7 into the drying chamber 1. Repeat until all the flat trays 7 are in the drying chamber 1. Then close the door 15 using handle 16. Heating is then applied using heating rod 18 to raise the internal temperature of the drying chamber 1, thereby drying the high-purity quartz sand on the flat trays 7. Simultaneously, the drive motor 9 rotates the shaft 10, causing the first bevel gear 11 to... The rotation of the cam causes the second bevel gear 12 to rotate simultaneously, which in turn causes the rotating rod 13 to rotate simultaneously, and the cam 14 to rotate simultaneously. The rotation of the cam 14 causes the frame 4 to vibrate slightly up and down via the spring 3, which in turn causes the flat tray 7 to vibrate slightly, causing the high-purity quartz sand in the flat tray 7 to vibrate. After drying, the door 15 is opened by the handle 16, and the flat tray 7 is pulled out from the mounting slot 5 via the mounting plate 6, thus completing the disassembly of the flat tray 7. Then, the dried high-purity quartz sand in the flat tray 7 can be poured out.
