Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of smelting equipment, specifically a high-purity quartz sand smelting equipment. Background Technology
[0002] When smelting quartz sand, we use a smelting furnace to process the quartz sand raw material at high temperature. Quartz sand smelting is a key step in the preparation of high-performance quartz products (such as fused quartz sand).
[0003] In existing smelting equipment, common methods include electric arc furnaces, which use electric current introduced through electrodes to heat and melt the furnace charge using the heat of the electric arc. This is used to melt quartz sand and flux. Alternatively, a medium-frequency induction furnace can be used to heat a graphite crucible and then melt the quartz sand inside. There are many ways to melt quartz sand, which will not be listed here. However, existing smelting furnaces have drawbacks. Quartz sand is typically fed into the furnace via a screw conveyor or feed conveyor belt. Because the feed position is fixed, the quartz sand accumulates inside the furnace, forming a sand pile with a pointed end. Even after the feed inlet is full, there is still space around it, affecting the feeding efficiency. Therefore, an improved high-purity quartz sand smelting device is needed to address this problem. Utility Model Content
[0004] The purpose of this invention is to provide a high-purity quartz sand smelting device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-purity quartz sand smelting device, comprising a base plate, a first support provided in the middle of the base plate, and second supports fixedly provided on both sides of the base plate. A smelting mechanism for smelting quartz sand is provided at the upper end of the first support. The smelting mechanism includes a heating crucible, a holding furnace, and a top cover. The heating crucible is movably mounted on the upper end of the first support via a rotating shaft. A holding furnace is fixedly mounted on the outside of the heating crucible. A top cover is movably mounted on one side of the upper end of the holding furnace via a rotating shaft. A feeding mechanism for feeding material into the heating crucible is provided at the upper end of the second support. The feeding mechanism includes a crossbar, a fixed ring, a rotating disk, and a discharge pipe. A crossbar is fixedly mounted on the upper end of the second support. A fixed ring is fixedly mounted in the middle of the crossbar. A rotating disk is movably mounted inside the fixed ring via a bearing. A discharge pipe is fixedly mounted at the lower end of the rotating disk.
[0006] Preferably, a number of teeth are uniformly fixed on the outer surface of the upper end of the rotating disk, a motor is fixedly installed on one side of the fixed ring, and a gear is fixedly installed on the power output shaft end of the motor. The teeth and the gear mesh with each other. The rotating disk can be driven to rotate by the motor and the gear in conjunction with the teeth, so that the quartz sand entering the crucible will not accumulate in one place.
[0007] Preferably, an electric push rod is movably mounted on one side of the surface of the heat preservation furnace via a rotating shaft. The movable end of the electric push rod is movably connected to the top cover via the rotating shaft. The retraction of the electric push rod can drive the top cover to rotate around the rotating shaft, thereby controlling the opening and closing of the top cover.
[0008] Preferably, a discharge port is fixedly provided on one side of the upper end of the heating crucible. After the quartz sand is melted in the heating crucible, the crucible can be tilted to easily pour out the molten quartz sand.
[0009] Preferably, a worm gear reducer is fixedly installed on one side of the upper end of the first support, and a servo motor is fixedly installed on one side of the worm gear reducer. The power output shaft of the servo motor is connected to the power input shaft of the worm gear reducer, and the power output shaft of the worm gear reducer is connected to the rotating shaft of the heating crucible. By rotating the servo motor in conjunction with the worm gear reducer, the heating crucible can be driven to rotate, thereby tilting the heating crucible and allowing the molten quartz sand inside to be poured out. The rotating disk of this device uses a motor because the rotating disk does not need to have its rotation angle controlled. When feeding, the motor rotates continuously to drive the rotating disk to rotate. However, when the heating crucible is tilted, attention needs to be paid to the angle and rotation speed, so a servo motor is required for transmission.
[0010] Preferably, the discharge pipe is located on one side of the lower end of the rotating disk. The rotating disk can drive the discharge pipe to rotate, thereby allowing for circumferential feeding into the heating crucible. This prevents the quartz sand inside the crucible from accumulating in one place, thus improving the uniformity of the feed and facilitating subsequent quartz sand smelting.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. In this invention, the quartz sand entering the rotating disc is automatically slid down to the lowest point of the disc, which is the discharge pipe. The quartz sand then enters the heating crucible through the discharge pipe. At this time, the rotating disc can be driven to rotate by a motor and gears in conjunction with a toothed clamp, thus enabling circular feeding. This prevents the quartz sand entering the crucible from accumulating in one place. This circular feeding improves the uniformity of the feed, facilitating subsequent quartz sand smelting.

[0018] 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.
[0019] Please see Figure 1-4This utility model provides a technical solution: a high-purity quartz sand smelting device, including a base plate 1, a first support 2 arranged in the middle of the base plate 1, and second supports 3 fixedly arranged on both sides of the base plate 1. A smelting mechanism for smelting quartz sand is arranged on the upper end of the first support 2. The smelting mechanism includes a heating crucible 4, a holding furnace 5, and a top cover 6. The heating crucible 4 is movably arranged on the upper end of the first support 2 through a rotating shaft. The holding furnace 5 is fixedly arranged on the outside of the heating crucible 4. The top cover 6 is movably arranged on one side of the upper end of the holding furnace 5 through a rotating shaft. A feeding mechanism for feeding material into the heating crucible 4 is arranged on the upper end of the second support 3. The feeding mechanism includes a crossbar 7, a fixing ring 8, a rotating disk 9, and a discharge pipe 10. The crossbar 7 is fixedly arranged on the upper end of the second support 3. The fixing ring 8 is fixedly arranged in the middle of the crossbar 7. The rotating disk 9 is movably arranged inside the fixing ring 8 through a bearing. The discharge pipe 10 is fixedly arranged on the lower end of the rotating disk 9.
[0020] A number of locking teeth 11 are uniformly fixed on the outer surface of the upper end of the rotating disk 9. A motor 12 is fixedly installed on one side of the fixing ring 8. A gear 13 is fixedly installed on the power output shaft end of the motor 12. The locking teeth 11 and the gear 13 mesh with each other. The rotating disk 9 can be driven to rotate by the motor 12, the gear 13 and the locking teeth 11, so that the quartz sand entering the crucible will not accumulate in one place.
[0021] An electric push rod 14 is movably mounted on one side of the surface of the heat preservation furnace 5 via a rotating shaft. The movable end of the electric push rod 14 is movably connected to the top cover 6 via the rotating shaft. The retraction of the electric push rod 14 can drive the top cover 6 to rotate around the rotating shaft, thereby controlling the opening and closing of the top cover 6.
[0022] A discharge port 15 is fixedly provided on one side of the upper end of the heating crucible 4. After the quartz sand is melted in the heating crucible 4, the molten quartz sand can be poured out by tilting the crucible through the discharge port 15.
[0023] A worm gear reducer 16 is fixedly installed on one side of the upper end of the first bracket 2. A servo motor 17 is fixedly installed on one side of the worm gear reducer 16. The power output shaft of the servo motor 17 is connected to the power input shaft of the worm gear reducer 16. The power output shaft of the worm gear reducer 16 is connected to the rotating shaft of the heating crucible 4. By cooperating with the servo motor 17 to rotate the worm gear reducer 16, the heating crucible 4 can be driven to rotate, so that the heating crucible 4 can be tilted, thereby pouring out the molten quartz sand inside. The rotating disk 9 of this device uses a motor 12 because the rotating disk 9 does not need to control the rotation angle. When feeding, the motor 12 rotates continuously to drive the rotating disk 9 to rotate. However, when the heating crucible 4 is tilted, attention needs to be paid to the angle and rotation speed, so the servo motor 17 is required for transmission.
[0024] The discharge pipe 10 is located on one side of the lower end of the rotating disk 9. The rotating disk 9 can drive the discharge pipe 10 to rotate, thereby feeding material into the heating crucible 4 in a ring. This prevents the quartz sand inside the crucible from accumulating in one place, thus improving the uniformity of feeding and facilitating the subsequent quartz sand smelting work.
[0025] Working principle: This device requires a matching conveyor belt or spiral conveyor. Compared with existing technologies, the conveyor belt or spiral conveyor does not require any special structure. Based on existing technology, it can transport quartz sand from a lower position to the rotating disk 9 at a higher position. Since the lower end of the rotating disk 9 is conical, the quartz sand inside the rotating disk 9 will automatically slide down to the lowest point of the rotating disk 9, which is the discharge pipe 10. The quartz sand then enters the heating crucible 4 through the discharge pipe 10. At this time, the rotating disk 9 can be rotated by the motor 12, gear 13 and clamping teeth 11, so as to carry out circular feeding, so that the quartz sand entering the crucible will not accumulate in one place. This circular feeding can improve the uniformity of feeding, which is conducive to the subsequent quartz sand melting work.
