Description

Technical Field

[0001] This utility model relates to the field of quartz sand purification technology, specifically a high-temperature roasting and purification device for quartz sand. Background Technology

[0002] Quartz melting is an important raw material for melting quartz glass and making quartz crucibles, quartz glass, and optical and medical instruments for purifying silicon. Currently, quartz sand is mainly used as raw material for quartz melting. Before melting, quartz sand usually needs to be purified to remove moisture and impurities from the surface of the quartz sand raw material.

[0003] In existing technologies, quartz sand is generally purified at high temperatures. However, the existing equipment for high-temperature purification of quartz sand has a relatively closed and fixed structure, and can only operate one batch of quartz sand at a time. The feeding and discharging efficiency is low, and because the temperature of the purified quartz sand is high, careful handling is required when handling the material, which poses certain safety hazards.

[0004] The high-temperature purification equipment for quartz sand disclosed in announcement number CN220300425U uses a lifting device and a horizontal drive device to drive the high-temperature resistant tank to move up and down and laterally, which facilitates the delivery of quartz sand out of the high-temperature purification box. It is easy to operate, highly efficient, and does not require direct contact between the operator and the high-temperature resistant tank, thus eliminating safety hazards and ensuring safety.

[0005] However, during the use of the device, the quartz sand clumps together, causing uneven heating of the quartz sand, which in turn affects the efficiency of high-temperature roasting and purification of the quartz sand.

[0006] Therefore, we urgently need to provide a high-temperature roasting and purification equipment for quartz sand. Summary of the Invention

[0007] The purpose of this invention is to provide a high-temperature roasting and purification device for quartz sand, in order to solve the problem mentioned in the background art that causes quartz sand to accumulate and agglomerate during use, resulting in uneven heating of the quartz sand and thus affecting the efficiency of high-temperature roasting and purification of quartz sand.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature roasting and purification device for quartz sand, comprising a purification box, an inner box, a feed inlet, a discharge outlet, and an infrared heating tube.

[0010] The vibration mechanism includes a motor, a rotating shaft, a stirring rod, a half gear, a movable plate, a mounting block, a spring, and a striking rod. The motor is fixedly installed on the top of the purification tank, the rotating shaft is fixedly installed on the output end of the motor, the stirring rod is fixedly installed on the outside of the rotating shaft, the half gear is fixedly installed on the outer side of the upper end of the rotating shaft, the movable plate is installed on the top inside the purification tank, the mounting block is fixedly installed on the left and right sides of the inner wall of the movable plate, one end of the spring is fixedly installed on the inner wall of the mounting block, and the striking rod is fixedly installed on the other end of the spring.

[0011] Preferably, solenoid valves are installed inside the feed inlet and discharge outlet, a cavity is provided between the purification box and the inner box, and the infrared heating tube is installed in the cavity.

[0012] Preferably, the inner wall of the movable plate is provided with racks on both the front and rear sides, and the racks mesh with the half gears. The mounting block is provided with a mounting groove, and the striking rod can slide along the mounting groove. By starting the motor, the rotating shaft and the half gear are driven to rotate. Under the meshing of the racks on the movable plate with the half gears, the movable plate swings back and forth, thereby causing the striking rod to strike the inner wall of the inner box, causing the inner box to vibrate, thereby dispersing the agglomerated quartz sand and improving the purification efficiency and quality of quartz sand.

[0013] Preferably, the mounting block has a T-shaped block on its top, and the purification box has a T-shaped groove on its inner upper surface. The T-shaped block is slidably connected to the inner wall of the T-shaped groove, and the T-shaped block and the T-shaped groove cooperate to support and guide the mounting block and the movable plate.

[0014] Preferably, there are multiple stirring rods, which are equidistantly distributed on the outside of the rotating shaft. When the rotating shaft rotates, it drives the stirring rods to rotate, stirring the quartz sand in different positions inside the inner box, so that the quartz sand is heated more evenly, thereby improving the purification efficiency of the quartz sand.

[0015] Preferably, the purification mechanism includes a purification box, an air pump, an exhaust pipe, an intake pipe, a filter screen, and an activated carbon layer.

[0017] Compared with the prior art, the beneficial effects of this utility model are: 1. This high-temperature roasting and purification equipment for quartz sand uses a vibration mechanism. During the rotation of the shaft, the half gear rotates, and the half gear meshes with the rack on the movable plate, causing the movable plate to swing back and forth. This causes the striking rod to strike the inner wall of the inner box, resulting in vibration of the inner box. This shakes off the quartz sand adhering to the inner wall of the inner box and disperses the agglomerated quartz sand, thereby improving the purification efficiency and quality of the quartz sand.

[0018] 2. This high-temperature roasting and purification equipment for quartz sand, by setting up a purification mechanism, starts the air pump to filter and adsorb the dust and harmful gases generated during purification through the filter screen and activated carbon layer, and then discharges them through the exhaust pipe to avoid dust and harmful gases from polluting the environment. After purification is completed, the discharge port is opened to discharge the purified quartz sand. Attached Figure Description

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. Example

[0022] Due to the existing technology, quartz sand tends to agglomerate during use, leading to uneven heating and affecting the efficiency of high-temperature roasting and purification. Please refer to [link to relevant documentation]. Figures 1-5 This embodiment provides a high-temperature roasting and purification device for quartz sand, which can improve the purification efficiency and quality of quartz sand. The device includes a purification chamber 1, an inner chamber 2, an inlet 3, an outlet 4, and an infrared heating tube 5. The inner chamber 2 is fixedly installed inside the purification chamber 1. The inlet 3 is fixedly installed at the top of the purification chamber 1, and the outlet 4 is fixedly installed at the bottom of the purification chamber 1. The infrared heating tube 5, model IPCH116-3, is installed between the purification chamber 1 and the inner chamber 2. Solenoid valves are installed inside the inlet 3 and the outlet 4. A cavity is formed between the purification chamber 1 and the inner chamber 2, and the infrared heating tube 5 is installed inside the cavity. The opening and closing of the inlet 3 and the outlet 4 are controlled by the solenoid valves. The infrared heating tube 5 heats and roasts the quartz sand inside the inner chamber 2 for purification. The purification chamber 1 is equipped with a purification device, which includes a vibration mechanism and a purification mechanism.

[0023] The vibration mechanism is located at the upper part of the inner chamber 2, and the purification mechanism is located on the right side of the purification chamber 1.

[0024] The vibration mechanism includes a motor 601, a rotating shaft 602, a stirring rod 603, a half gear 604, a movable plate 605, a mounting block 606, a spring 607, and a striking rod 608. The motor 601 is fixedly mounted on the top of the purification chamber 1. The motor 601 is a Y112-4 model. The rotating shaft 602 is fixedly mounted on the output end of the motor 601. Multiple stirring rods 603 are fixedly mounted on the outside of the rotating shaft 602, evenly distributed on its outer side. When the rotating shaft 602 rotates, it drives the stirring rods 603 to rotate, stirring the quartz sand at different locations inside the inner chamber 2, making the quartz sand heat more evenly and thus improving the quartz sand purification efficiency. The half gear 604 is fixedly mounted on the upper outer side of the rotating shaft 602. The movable plate 605 is mounted on the top inside the purification chamber 1. Gear racks are provided on the front and rear sides of the inner wall of the movable plate 605, and these racks mesh with the half gear 604. The mounting block 606 has an internal mounting groove. The striking rod 608 can slide along the mounting groove. The starting motor 601 drives the rotating shaft 602 and the half-gear 604 to rotate. With the half-gear 604 meshing with the rack in the movable plate 605, the movable plate 605 swings back and forth, causing the striking rod 608 to strike the inner wall of the inner chamber 2, resulting in vibration of the inner chamber 2. This disperses the agglomerated quartz sand, improving the purification efficiency and quality of the quartz sand. The mounting block 606 is fixedly installed on the inner wall of the movable plate 605. On both sides, T-shaped blocks are provided on the top of the mounting block 606, and T-shaped grooves are provided on the upper surface of the inner side of the purification box 1. The T-shaped blocks are slidably connected to the inner wall of the T-shaped grooves. The T-shaped blocks and T-shaped grooves cooperate to support and guide the mounting block 606 and the movable plate 605. One end of the spring 607 is fixedly installed on the inner wall of the mounting block 606. The spring 607 prevents the striking rod 608 from causing excessive impact on the inner box 2. The striking rod 608 is fixedly installed on the other end of the spring 607. Example

[0025] Based on Example 1, please refer to Figures 1-5To prevent dust and harmful gases generated during purification from polluting the environment, this device is also equipped with a purification mechanism. The purification mechanism includes a purification chamber 701, a vacuum pump 702, an exhaust pipe 703, an exhaust duct 704, a filter screen 705, and an activated carbon layer 706. The purification chamber 701 is fixedly installed on the right side of the purification chamber 1. The vacuum pump 702 is fixedly installed at the bottom of the purification chamber 701. The exhaust pipe 703 is connected to the output end of the vacuum pump 702, and the exhaust duct 704 is connected to the top of the purification chamber 701. The exhaust duct 704 extends to the bottom of the purification chamber 701. One end of the purification chamber 701 is connected to the inner chamber 2. During the purification of quartz sand, the air pump 702 is started to filter and adsorb the dust and harmful gases generated during purification through the filter screen 705 and the activated carbon layer 706, and then discharge them through the exhaust pipe 703 to avoid dust and harmful gases from polluting the environment. The filter screen 705 is installed at the upper part of the purification chamber 701 to filter the dust generated during purification, and the activated carbon layer 706 is installed at the lower part of the purification chamber 701 to adsorb the sulfur-containing gases generated during purification.

[0026] In operation, the quartz sand to be purified is poured into the inner chamber 2 through the feed inlet 3. The inner chamber 2 is then heated by the infrared heating tube 5, thereby calcining and purifying the quartz sand inside. Simultaneously, the motor 601 is started, driving the rotating shaft 602 and the stirring rod 603 to rotate, stirring the quartz sand inside the inner chamber 2 to ensure even heating. During the rotation of the rotating shaft 602, the half-gear 604 rotates, engaging with the rack and pinion of the movable plate 605, causing the movable plate 605 to oscillate back and forth. The striking rod 608 strikes the inner wall of the inner box 2, causing the inner box 2 to vibrate. This shakes off the quartz sand adhering to the inner wall of the inner box 2 and disperses the agglomerated quartz sand, thereby improving the purification efficiency and quality of the quartz sand. During the purification process, the vacuum pump 702 is started to filter and adsorb the dust and harmful gases generated during purification through the filter screen 705 and the activated carbon layer 706, and then discharge them through the exhaust pipe 703 to avoid pollution of the environment by dust and harmful gases. After purification is completed, the discharge port 4 is opened to discharge the purified quartz sand.
