Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, specifically a drying equipment for quartz sand production. Background Technology

[0002] Quartz sand is a granular material produced from natural quartz minerals (mainly composed of silicon dioxide, SiO2) through processes such as crushing, screening, washing, and drying. It is one of the most common minerals in nature, widely found in rocks, sand, and soil. Due to its excellent physical and chemical properties, quartz sand has important applications in many industrial fields. Quartz sand drying is a crucial step in mineral processing and subsequent processing; its purpose is to remove surface moisture from the quartz sand, ensuring product quality and process stability.

[0003] Chinese patent (authorization announcement number: 221593344 U, authorization announcement date: 2024.08.23) proposes a high-efficiency drying equipment for quartz sand. The quartz sand drying equipment uses a second bolt and a first bolt to fix the main body, top cover and base together. The user can easily disassemble the main body, thereby making it easier to clean or maintain the inner wall of the main body and the stirring rod on the top cover, thus extending the service life of the equipment.

[0004] However, the above-mentioned drying device only uses heating pipes around the perimeter to heat and dry the quartz sand. This method is relatively simple, and setting heating pipes only on the side will also lead to poor heating efficiency, resulting in low drying efficiency of quartz sand. In order to improve the drying efficiency of the device, we propose a drying equipment for quartz sand production. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a drying device for quartz sand production. Air blown out by a fan is heated by heating wires inside a hollow box, and then blown into the drying chamber through a one-way air outlet valve on the air duct. This air-dries the quartz sand inside the drying chamber. During the rotation of the drying chamber, heat is transferred to the quartz sand via a heat-conducting plate in conjunction with the spiral blades. Through these two heating methods, the quartz sand is thoroughly dried, significantly improving the drying efficiency and solving the problems mentioned earlier.

A heat-conducting plate 16 is fixedly installed, and several one-way air valves 17 are fixedly connected to the air duct 12. A screening assembly 3 is fixedly installed on the front side of the base plate 1. The drying assembly 4 also includes a fan 10, which is fixedly installed on the base plate 1. The air outlet of the fan 10 is fixedly connected to the air inlet pipe 11, and a feed pipe 15 is fixedly connected to the connecting sleeve 13. Several heating wires are installed inside the hollow box 14, and an electric heating plate is embedded in the heat-conducting plate 16. Spiral blades 8 and a limiting frame 9 are fixedly installed inside the drying chamber 2, and the limiting frame 9 is rotatably connected to the air duct 12.

[0030] In use, quartz sand is loaded into the drying chamber 2 through the feed pipe 15 and the connecting sleeve 13. Then, under the action of the spiral blades 8, the quartz sand is pushed forward. Then, the blower 10 introduces natural air into the hollow box 14 through the air inlet pipe 11. Under the heating of the electric heating wire in the hollow box 14, the natural air is heated and introduced into the air guide pipe 12. Then, the hot air is blown into the drying chamber 2 through the one-way air outlet valve 17. At the same time, the electric heating plate in the heat conduction plate 16 also starts to work, heating the heat conduction plate 16, thereby transferring heat to the quartz sand. The quartz sand is fully heated and dried through two methods.

[0031] An arc-shaped plate 20 is fixedly installed on the base plate 1, and several auxiliary wheels 21 are rotatably installed on the arc-shaped plate 20. Several sliding slots 6 are opened on the outer side of the drying chamber 2, and the sliding slots 6 cooperate with the auxiliary wheels 21. A bidirectional motor 18 is fixedly installed on the base plate 1. Both sets of drive shafts of the bidirectional motor 18 are fixedly fitted with drive rings 19. Two sets of driven rings 7 are fitted on the outer side of the drying chamber 2.

Two sets of auxiliary blocks 22 are fixedly installed on the base plate 1, and the drive shafts of the bidirectional motor 18 are rotatably connected to the corresponding auxiliary blocks 22.

[0032] When in use, start the fan 10, which blows natural air into the air inlet pipe 11. At the same time, start the bidirectional motor 18. The two sets of drive shafts of the bidirectional motor 18 drive the drive ring 19 to rotate. With the cooperation of the driven ring 7 and the drive ring 19, and with the cooperation of the auxiliary wheel 21 and the sliding groove 6, the drying chamber 2 starts to rotate. The auxiliary wheel 21 on the arc plate 20 also plays a supporting role, and the auxiliary block 22 plays a supporting role for the drive shaft of the bidirectional motor 18. During the rotation of the drying chamber 2, the spiral blades 8 will rotate, thereby sending the quartz sand forward.

The limiting plate 28 restricts the position of the screen 25, and the spring on the protrusion 27 can reset the position of the screen 25. The mounting hole 23 on the base plate 1 is used to install this equipment.

[0035] Working principle: When in use, start the fan 10, which blows natural air into the air inlet pipe 11. At the same time, start the bidirectional motor 18. The two sets of drive shafts of the bidirectional motor 18 drive the active ring 19 to rotate. With the cooperation of the driven ring 7 and the active ring 19, and with the cooperation of the auxiliary wheel 21 and the sliding groove 6, the drying chamber 2 starts to rotate. The auxiliary wheel 21 on the arc plate 20 also plays a supporting role, and the auxiliary block 22 plays a supporting role for the drive shaft of the bidirectional motor 18. During the rotation of the drying chamber 2, the spiral blades 8 will rotate, thereby sending the quartz sand forward.

[0036] Then, the quartz sand is loaded into the drying chamber 2 through the feed pipe 15 and the connecting sleeve 13. Under the action of the spiral blades 8, the quartz sand is pushed forward. Then, the fan 10 introduces natural air into the hollow box 14 through the air inlet pipe 11. Under the heating of the electric heating wire in the hollow box 14, the natural air is heated and introduced into the air guide pipe 12. Then, the hot air is blown into the drying chamber 2 through the one-way air outlet valve 17. At the same time, the electric heating plate in the heat conduction plate 16 also starts to work, heating the heat conduction plate 16, thereby transferring heat to the quartz sand. The quartz sand is fully heated and dried through two methods.

[0037] After the quartz sand is dried, it is sent out of the drying chamber 2 by the spiral blades 8 and enters the loading frame 24. The operator pulls the screen 25 back and forth by pulling the ring and the rope 26 to prevent the quartz sand from clogging. The limiting plate 28 restricts the position of the screen 25, and the spring on the protrusion 27 can reset the position of the screen 25. The mounting hole 23 on the base plate 1 is used to install this equipment.
