Description

Technical Field

[0001] This utility model relates to the field of high-purity quartz sand processing technology, and in particular to a continuous precision temperature-controlled roasting device for high-purity quartz sand. Background Technology

[0002] High-purity quartz sand, as a key basic material with excellent high-temperature resistance, chemical stability, and optical properties, is widely used in high-tech fields such as semiconductors, photovoltaics, optical glass, and high-end ceramics. Its quality directly affects the performance and reliability of downstream products. Therefore, industrial production places extremely high demands on the purity and uniformity of high-purity quartz sand. In the production and processing of high-purity quartz sand, calcination is a crucial process. Calcination effectively removes moisture, organic impurities, and some volatile components from the quartz sand, while also adjusting its crystal structure and physical properties, laying a good foundation for subsequent purification and molding processes. This invention is a continuous, precise temperature-controlled calcination device for high-purity quartz sand.

[0003] In the current technology for high-purity quartz sand roasting, many devices lack effective material turning structures or have relatively simple turning methods. This makes it easy for quartz sand to accumulate during the roasting process, preventing it from making full and complete contact with the heat source generated by the heating components. Consequently, some areas of quartz sand are not roasted sufficiently, while other areas are over-roasted due to prolonged proximity to the heat source. Ultimately, this results in significant differences in the roasting effect of the same batch of quartz sand, making it difficult to guarantee product quality consistency and failing to meet the high-quality and high-stability requirements of downstream high-tech fields for high-purity quartz sand.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Please refer to Figures 1 to 6 Example 1: This utility model proposes a continuous precision temperature-controlled roasting device for high-purity quartz sand, comprising: a base frame 1; a flipping table 12 is mounted on the base frame 1 via pins, a frame 2 is mounted on the upper end of the flipping table 12, two sets of support rollers 21 are mounted on the frame 2 via bearing seats, and two sets of positioning plates 22 are mounted on the frame 2 via bolts, positioning wheels 221 are mounted on the positioning plates 22, and waist-shaped grooves are provided on the positioning plates 22; a rotating cylinder 3 is mounted above the frame 2, a drainage groove 33 is arranged in a ring at the left end of the rotating cylinder 3, a heat-conducting baffle 35 is fixed inside the rotating cylinder 3, and an arc-shaped guide plate 36 is fixed at the right end of the inner side of the rotating cylinder 3; a feed box 4 is provided at the left end of the rotating cylinder 3, and the rotating cylinder 3 and the feed box 4 are rotatably connected; a feed inlet 43 is provided at the upper end of the feed box 4, and a feed hopper 431 is mounted on the upper end of the feed inlet 43 via bolts.

[0025] In this embodiment of the invention, four casters 11 are installed at the lower end of the base frame 1. A hydraulic cylinder 13 is installed between the base frame 1 and the flipping table 12. An oil tank 14 is installed on the base frame 1, and a hydraulic pump motor 141 is installed on the oil tank 14. A control oil circuit 142 is connected between the hydraulic pump motor 141 and the hydraulic cylinder 13. The function of the four casters 11 is to enable the base frame 1 and the entire device to move flexibly, so as to facilitate the adjustment of the device position according to the actual layout of the production site and effectively improve the utilization rate of the site space. The oil tank 14 is used to store the hydraulic oil required by the hydraulic system. The hydraulic pump motor 141 provides a reliable oil supply for the operation of the cylinder 13. After the hydraulic pump motor 141 starts, it can deliver hydraulic oil to the cylinder 13 through the control oil circuit 142, driving the cylinder 13 to perform extension and retraction actions. This, in turn, drives the flipping table 12 and the frame 2 and rotating cylinder 3 above to adjust their tilt angles synchronously. During the roasting process, the angle can be finely adjusted to ensure that the high-purity quartz sand has sufficient roasting time in the rotating cylinder 3, ensuring thorough roasting. During the unloading stage, the tilt angle can be increased to speed up the material discharge, while avoiding material residue in the rotating cylinder 3, thus balancing production flexibility and processing efficiency.

[0026] In this embodiment of the utility model, a control box 15 is installed on the base frame 1, and a nylon plate 121 is installed on the flipping table 12. The nylon plate 121 is located between the flipping table 12 and the frame 2. Its function is as follows: the control box 15 can centrally integrate and regulate the operating parameters of each core component of the device, such as the speed of the drive motor 232, the temperature of the first heater 37 and the second heater 38, and the start and stop of the hydraulic pump motor 141, so as to realize one-button operation and precise control of the entire roasting process, which greatly reduces the difficulty of manual operation; the nylon plate 121 has excellent wear resistance and buffering performance, which can isolate the flipping table 12 and the frame 2, reduce the direct friction loss between the two during the operation or angle adjustment of the device, extend the service life of the flipping table 12 and the frame 2, and at the same time, when the device vibrates during operation, it can play a buffering and shock absorption role, avoid damage to the components caused by vibration collision between the flipping table 12 and the frame 2, and ensure the overall operational stability of the device.

[0027] In Example 2, based on Example 1, a first support 31 and a second support 32 are welded onto the rotating cylinder 3. The first support 31 has two sets. An annular frame 311 and a toothed ring 321 are respectively bolted onto the first support 31 and the second support 32. The annular frame 311 contacts the support roller 21, and the positioning wheel 221 on the positioning plate 22 contacts the side of the annular frame 311. Its function is: the support roller 21 provides bottom support for the rotating cylinder 3 through rolling contact with the annular frame 311, and at the same time converts the sliding friction of the rotating cylinder 3 into rolling friction, which greatly reduces the frictional resistance of the rotating cylinder 3 during operation and ensures smooth rotation of the rotating cylinder 3; the positioning wheel 221 limits and blocks from the side of the annular frame 311, which can effectively prevent the rotating cylinder 3 from lateral deviation during high-speed operation, ensuring that the rotating cylinder 3 always maintains the preset stable running trajectory, avoiding uneven distribution of roasted materials due to deviation, or collision damage between the rotating cylinder 3 and other components.

[0028] In Example 3, based on Examples 1 and 2, a welding table 23 is welded onto the frame 2. A reducer 231 is mounted on the welding table 23, and a gear is mounted on the output shaft of the reducer 231. A drive motor 232 is mounted on the welding table 23, and the output shaft of the drive motor 232 is connected to the input shaft of the reducer 231 via a coupling. The gear on the output shaft of the reducer 231 meshes with a gear ring 321. A first heater 37 and a second heater 38 are mounted on the rotating cylinder 3. A first support frame 371 is installed between the first heater 37 and the frame 2, and a second support frame 381 is installed between the second heater 38 and the frame 2. A third support frame 41 is installed between the feed box 4 and the frame 2, and a drain hopper 42 is fixedly installed at the lower end of the feed box 4. Its function is to transmit the power generated by the drive motor 232 through the coupling. The reducer 231 transmits the appropriate speed and torque to the output shaft gear through the reduction and torque amplification effect. Then, through the meshing transmission of the gear and gear ring 321, it drives the rotating drum 3 to operate at a uniform and stable speed, ensuring that the high-purity quartz sand in the rotating drum 3 can be fully agitated and evenly contacted with the heat source. The first support frame 371 provides fixed support for the first heater 37, and the second support frame 381 provides stable limiting for the second heater 38, ensuring that the first heater 37, the second heater 38 and the rotating drum 3 maintain a reasonable distance, so as to achieve precise temperature control and uniform heating of the material in the rotating drum 3. The drain hopper 42 can collect and drain the moisture generated in the feed box 4 due to roasting, preventing the moisture from accumulating in the feed box 4 and seeping into the rotating drum 3, affecting the roasting quality of the material. At the same time, it facilitates the unified treatment of wastewater in the future, which meets the requirements of environmental protection production.

[0029] The working principle of this embodiment is as follows: The entire system is started by controlling the electrical box 15. The operator feeds the high-purity quartz sand to be roasted through the feed hopper 431. After entering the feed box 4 through the feed inlet 43, the material flows smoothly into the rotating drum 3. Moisture in the material flows into the feed box 4 through the drain trough 33 at the left end of the rotating drum 3, and is then discharged through the drain hopper 42 at the lower end of the feed box 4. Subsequently, the drive motor 232 starts, and its power is transmitted to the reducer 231 via the coupling. After the reducer 231 reduces speed and increases torque, it drives the rotating drum 3 to rotate uniformly around its own axis through the meshing of the output shaft gear and the gear ring 321. Simultaneously, the first heater 37 and the second heater 38 begin heating under the control of the electrical box 15. The heat-conducting baffle 35 fixed inside the rotating drum 3 can, on the one hand, heat the first heater 37 and the second heater 38... The heat transferred to the rotating drum 3 is evenly conducted and diffused to avoid excessive local heat concentration. On the other hand, the rotating drum 3 can help to turn the quartz sand when it rotates, further breaking up the material accumulation state and ensuring that the quartz sand is in uniform contact with the heat source in all directions, providing a stable and precise roasting temperature for the quartz sand in the rotating drum 3. If it is necessary to adjust the residence time of the quartz sand in the rotating drum 3 or the unloading speed, the hydraulic pump motor 141 can be started by controlling the electrical box 15. The hydraulic pump motor 141 draws hydraulic oil from the oil tank 14 and delivers it to the oil cylinder 13 through the control oil circuit 142. The oil cylinder 13 extends and retracts, driving the flipping table 12 and the frame 2 above and the rotating drum 3 to adjust the tilt angle, thereby meeting the needs of different roasting processes. The roasted quartz sand is finally discharged from the discharge end of the rotating drum 3, realizing continuous roasting operation.
