Abstract
Description
Technical Field
[0001] This utility model relates to the field of quartz sand production technology, specifically to a high-purity quartz sand drying device. Background Technology
[0002] Quartz sand is formed by crushing and processing mined quartz. High-purity quartz sand is quartz sand with relatively high purity and is often used in the production fields of construction, chemical industry, plastics and casting. Quartz sand mining and production requires the use of some equipment for processing, and drying equipment is one of them. The drying equipment can dry the moisture in the quartz sand. The dried quartz sand is less likely to crack and has a better performance.
[0003] Existing high-purity quartz sand drying equipment typically uses a heating method to dry the high-purity quartz sand by placing it inside a mixing tank and stirring it. During the drying of large quantities of quartz sand, due to the weight of the quartz sand itself, it tends to accumulate at the bottom of the mixing tank. The lack of a device to dry the quartz sand in layers affects the efficiency of drying the quartz sand to some extent.
[0004] Therefore, in order to solve the above problems, this utility model provides a high-purity quartz sand drying device. Utility Model Content

[0007] As a further aspect of this invention: a feeding channel is provided between the feed inlet and the drying chamber, and a flow-limiting device is installed within the feeding channel. The flow-limiting device includes a flow-limiting rotating shaft and multiple distribution baffles, which are evenly distributed on the outer circumference of the flow-limiting rotating shaft. A damping strip is provided on one side wall of the feeding channel to impede the movement of the distribution baffles; the damping strip is arranged parallel to the distribution baffles. By structurally configuring the flow-limiting device in the feeding channel, the feeding speed can be controlled to alleviate the drying pressure on the chamber and improve the drying efficiency of the quartz sand within the drying chamber.
[0008] As a further embodiment of this invention: a fixed bracket is provided at the bottom of the drive motor, the drive motor is located at the higher end of the heating guide plate, and the stirring paddle is positioned close to the heating guide plate. This arrangement of the stirring paddle close to the heating guide plate allows for continuous stirring and dispersion of the quartz sand falling onto the heating guide plate, thereby improving drying efficiency.
[0009] As a further embodiment of this invention: the plurality of heating guide plates are uniformly and obliquely fixedly arranged on both side walls inside the drying chamber in a vertical direction. The plurality of heating guide plates includes a first heating guide plate, a second heating guide plate, and a third heating guide plate. The lower end of the first heating guide plate is positioned above the higher end of the second heating guide plate, and the lower end of the second heating guide plate is positioned above the higher end of the third heating guide plate. The heating guide plates are PTC constant temperature heating plates. Through the structural arrangement of the plurality of heating guide plates, and by setting the heating guide plates to different temperatures, multi-stage temperature-controlled drying of quartz sand from top to bottom can be achieved.

Through the structural setting of multiple heating guide plates and the use of a stirring device, multi-stage temperature-controlled drying of quartz sand from top to bottom can be achieved, improving drying efficiency.
[0013] By setting the first heating guide plate, the second heating guide plate, and the third heating guide plate to different temperatures, thermal stress can be avoided from causing the quartz sand to crack.
[0014] By controlling the flow restriction device in the feed channel, the feed speed can be reduced to alleviate the drying pressure on the chamber and improve the drying efficiency of quartz sand in the drying chamber. Attached Figure Description
