Abstract
Description
Technical Field
[0001] This utility model relates to the field of quartz glass technology, specifically to a raw material mixing and stirring device for quartz glass production and processing. Background Technology
[0002] Quartz glass is made by melting various pure natural quartz crystals. It has an extremely small coefficient of linear expansion, only 1 / 10 to 1 / 20 that of ordinary glass, and excellent thermal shock resistance. It also has high heat resistance, with a typical operating temperature of 1100–1200 degrees Celsius and short-term operating temperatures reaching 1400 degrees Celsius. Quartz glass is mainly used in laboratory equipment and refining equipment for special high-purity products. It is primarily made from raw materials such as crystal, silica, and silicides through high-temperature melting or chemical vapor deposition.
[0003] However, in the current process of mixing raw materials for quartz glass, the raw materials tend to stick to the inner wall of the mixing drum and cannot participate in the mixing, thus resulting in a waste of resources. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a raw material mixing and stirring device for quartz glass production and processing.
[0005] To achieve the above objectives, the technical solution of this utility model is as follows:
[0006] A raw material mixing and stirring device for quartz glass production and processing includes a stirring drum. A feed pipe for feeding is inclinedly arranged on the upper part of one side of the stirring drum, and a discharge pipe for discharging is arranged at the bottom of the stirring drum. A fixed cylinder with a through hole on one side is fixed at the top of the stirring drum. A rotatable lead screw is arranged inside the fixed cylinder. A movable ring is threaded on the lead screw. A connecting rod is fixed at one end of the movable ring through the through hole and slidably connected to the through hole. A scraper for cleaning the inner wall of the stirring drum is fixed at the end of the connecting rod. Several stirring rods are fixed at the bottom of the lead screw.
[0007] Preferably, the top surface of the stirring rod is in contact with the bottom surface of the fixed cylinder, and the bottom surface of the stirring rod is in contact with the inner bottom surface of the stirring cylinder.
[0008] Preferably, the connecting rod is also provided with a scraper for cleaning the outer wall of the fixed cylinder.
[0009] Preferably, the through hole on the fixed cylinder is opposite to the feed pipe.
[0010] Preferably, both scraper one and scraper two are configured as annular scrapers with a conical bottom surface, the outer diameter of scraper one remains unchanged, and the inner diameter of scraper two remains unchanged.
[0011] Preferably, the first scraper, the second scraper, and the moving ring are at the same height.
[0012] Preferably, the height difference between the highest point of the connection between the feed pipe and the mixing drum and the top surface inside the mixing drum is not less than the height of the scraper.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. This utility model uses a lead screw to drive a stirring rod to stir the raw materials. At the same time, the moving ring descends through the threaded connection between the moving ring and the lead screw. The descent of the moving ring drives the second scraper and the first scraper to descend, thereby cleaning the outer wall of the fixed cylinder and the inner wall of the stirring cylinder by the second scraper and the first scraper, respectively. This avoids the raw materials from sticking to the inner wall of the stirring cylinder and the outer wall of the fixed cylinder, thus avoiding the waste of resources. It has high practical value.
[0015] 2. This utility model uses a fixed cylinder to ensure that the moving ring does not rotate when the screw rotates, thereby achieving the lifting and lowering of the moving ring and ensuring the stable progress of the cleaning work. Attached Figure Description

[0022] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.
[0023] like Figure 1 As shown, this utility model discloses a raw material mixing and stirring device for quartz glass production and processing, comprising a stirring drum 1. Multiple support rods are arranged on the side of the stirring drum 1, and the bottoms of the multiple support rods are fixed to the same base plate. A feed pipe 2 is inclinedly arranged on the upper part of one side of the stirring drum 1, and a discharge pipe 3 is arranged at the bottom of the stirring drum 1. A solenoid valve is installed on the discharge pipe 3. Raw materials are added through the feed pipe 2, and the discharge is controlled by the solenoid valve on the discharge pipe 3. A drive motor 4 is installed at the center of the top of the stirring drum 1. Figure 3 As shown, the output end of the drive motor 4 is provided with a lead screw 6 that passes through the mixing drum 1 and is rotatably connected to the mixing drum 1. The lead screw 6 is located inside the mixing drum 1, and several stirring rods 8 are fixed to the bottom of the lead screw 6. A moving ring 11 is threaded on the lead screw 6. A connecting rod 9 is fixed to one end of the moving ring 11, and a scraper 7 is fixed to the end of the connecting rod 9. Figure 4 As shown, a scraper 10 is also provided on the connecting rod 9. The drive motor 4 drives the lead screw 6 to rotate, thereby driving the stirring rod 8 to stir the raw materials.
[0024] like Figure 2 As shown, a fixed cylinder 5 is fixed at the top of the mixing drum 1. The fixed cylinder 5 is located inside the scraper 2 10, and the moving ring 11 and the lead screw 6 are located inside the fixed cylinder 5. A through hole is opened on one side of the fixed cylinder 5, and the connecting rod 9 passes through the through hole and is slidably connected to the through hole. The fixed cylinder 5 ensures that the moving ring 11 will not rotate when the lead screw 6 rotates, thereby realizing the lifting and lowering of the moving ring 11. Then, the lowering of the moving ring 11 drives the scraper 2 10 and the scraper 1 7 to descend. Thus, the scraper 2 10 and the scraper 1 7 clean the outer wall of the fixed cylinder 5 and the inner wall of the mixing drum 1, respectively. At the same time, the moving ring 11 can clean the inner wall of the fixed cylinder 5 to a certain extent, avoiding the raw materials from adhering to the inner wall of the mixing drum 1 and the outer wall of the fixed cylinder 5, which would cause waste of resources. The scraper 1 7 and the scraper 2 10 are both set as annular scrapers with a conical bottom surface. The outer diameter of the scraper 1 7 remains unchanged, and the inner diameter of the scraper 2 10 remains unchanged. The conical surface is conducive to the cleaning work on the one hand, and avoids the raw materials from adhering to the scraper on the other hand.
[0025] like Figure 2 As shown, the through hole on the fixed cylinder 5 is opposite to the feed pipe 2, ensuring that when the raw material enters the mixing cylinder 1 through the feed pipe 2, it will not directly enter the upper part of the fixed cylinder 5 through the through hole. The top surface of the stirring rod 8 is in contact with the bottom surface of the fixed cylinder 5, and the bottom surface of the stirring rod 8 is in contact with the inner bottom surface of the mixing cylinder 1, ensuring that the connecting rod 9 will not be separated from the limit of the fixed cylinder 5. The height of scraper 1 7, scraper 2 10 and moving ring 11 is the same, ensuring that scraper 1 7 and scraper 2 10 can descend to the top of the stirring rod 8 for comprehensive cleaning. The height difference between the highest point of the connection position between the feed pipe 2 and the mixing cylinder 1 and the inner top surface of the mixing cylinder 1 is not less than the height of scraper 1 7, to prevent the raw material from falling onto the top plane of the scraper.
[0026] In use, the raw materials are added into the mixing drum 1 through the feed pipe 2. The drive motor 4 drives the lead screw 6 to rotate back and forth, which in turn drives the stirring rod 8 to stir. After the raw materials are mixed, they are discharged through the discharge pipe 3. As the raw materials are gradually discharged, the drive motor 4 drives the lead screw 6 to rotate, which in turn drives the scraper 1 7, scraper 2 10 and moving ring 11 to gradually descend and clean the inner wall of the mixing drum 1, the outer wall of the fixed drum 5 and the inner wall of the fixed drum 5 respectively until all the raw materials are discharged. The scraper 1 7, scraper 2 10 and moving ring 11 are always located above the raw materials.
[0027] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
