Abstract
Description
Technical Field
[0001] This utility model relates to the field of quartz crucible manufacturing technology, and in particular to a quartz crucible cleaning and drying device. Background Technology
[0002] After the quartz crucible is manufactured, in order to ensure the cleanliness of the product and facilitate its rapid use, it needs to be sent to the spray channel for cleaning after the product has been cut and inspected. This washes away impurities such as particles and powder on its outer surface and dries it quickly with high-temperature gas.
[0003] When quartz crucibles are rinsed through traditional spray channels, the crucible opening faces downwards during the spraying process. For the spraying of the inner wall of the crucible, an atomizing nozzle with water outlet at the top is used to spray and rinse the inner wall of the crucible. In this spraying method, because the water flow is relatively dispersed, the impact force on the inner wall of the crucible is small. Dust and particulate impurities in the inner wall of the crucible need to be sprayed for a longer time to remove them, increasing the amount of water used. Similarly, during the drying process of the crucible, it is impossible to concentrate the high-temperature airflow to spray onto the inner wall of the crucible, resulting in low drying efficiency of the inner wall of the crucible. Utility Model Content
[0004] This disclosure relates to a quartz crucible cleaning and drying device to address the problem that when quartz crucibles are rinsed through a traditional spray channel, the crucible opening faces downwards during the spraying process. For the spraying of the inner wall of the crucible, an atomizing nozzle with water outlet at the top is used. In this spraying method, because the water flow is relatively dispersed, the impact force on the inner wall of the crucible is small, and dust and particulate impurities in the inner wall of the crucible require a longer spraying time to remove, increasing water consumption. Similarly, during the crucible drying process, it is impossible to concentrate the high-temperature airflow onto the inner wall of the crucible, resulting in low drying efficiency.
[0005] In a first aspect, this disclosure provides a quartz crucible cleaning and drying device, specifically comprising: a crucible conveying platform, a conveying platform base fixedly connected to the lower part of the crucible conveying platform, a lifting drive component fixedly connected to the front and rear of the conveying platform base by screws, a lifting screw fixedly connected to the upper end of the rotating shaft of the lifting drive component, the upper end of the lifting screw rotatably connected to the lower surface of the crucible conveying platform, a clamping push cylinder fixedly connected to the front and rear of the crucible conveying platform, a crucible clamping frame fixedly connected to the outer end of the push rod of the clamping push cylinder, the crucible clamping frame movably connected to the front and rear walls of the crucible conveying platform, and a cleaning inner spray pipe and an inner drying pipe slidably connected to the bottom of the crucible conveying platform.
[0006] In at least some embodiments, a side guide port is provided through the front and rear walls of the crucible conveyor platform, and the side guide port is slidably connected to the crucible clamping frame. A vertical guide port is provided through the bottom of the crucible conveyor platform, and the front vertical guide port is slidably connected to the cleaning inner spray pipe, and the rear vertical guide port is slidably connected to the inner drying pipe.
[0007] In at least some embodiments, two crucible clamps are rotatably connected to the end of the crucible clamping frame. The axis of the crucible clamps is perpendicular to the upper surface of the crucible conveying table. A rotary drive is fixedly connected to the upper surface of the right end support of the rear crucible clamping frame by screws. The rotating shaft of the rotary drive is fixedly connected to the support shaft of the right end crucible clamp.
[0008] In at least some embodiments, the cleaning inner nozzle has an "L" shaped structure, and a nozzle lifting push seat is welded to the bottom of the cleaning inner nozzle. A nozzle spiral push hole is longitudinally opened in the middle of the nozzle lifting push seat, and the nozzle spiral push hole is spirally connected to the lifting screw located in front.
[0009] In at least some embodiments, the lower end of the inner cleaning nozzle is fixedly connected to a nozzle water supply pipe, and an oblique spray hole is provided through the outer pipe wall of the inner cleaning nozzle, the oblique spray hole being opened at an angle.
[0010] In at least some embodiments, the bottom of the inner drying tube is connected to a drying tube pusher by welding, and a drying tube spiral push hole is opened through the center of the drying tube pusher.

[0012] This utility model provides a quartz crucible cleaning and drying device, which has the following beneficial effects:
[0013] In this invention, the quartz crucible is transported via a roller-type conveyor table. Once the crucible reaches the designated area, two clamping cylinders pull the two crucible clamping frames towards the center of the conveyor table, causing the crucible clamps to move towards the center and contact the outer surface of the quartz crucible, forming a rolling connection and positioning the crucible. A lifting drive unit then rotates the lifting screw, and the spiral transmission formed by the lifting screw, the nozzle spiral push hole, and the drying tube spiral push hole pushes the inner cleaning nozzle and inner drying tube upwards and inserts them into the quartz crucible. The "L"-shaped cleaning nozzle and the inner drying pipe are close to the inner wall of the quartz crucible. The cleaning nozzle is connected to water pressure through the nozzle water supply pipe. The water flow is sprayed obliquely through the spiral push hole of the nozzle to the inner wall of the quartz crucible, rinsing the inner wall of the quartz crucible. As the rotary drive drives the crucible clamp to rotate, the crucible clamp and the quartz crucible form a rolling connection, adapting to the rotation of the crucible. As the quartz crucible rotates, the inner wall of the crucible circulates close to the cleaning nozzle for rinsing. This rinsing method has a concentrated water flow and high rinsing efficiency, which can improve the rinsing efficiency of the crucible and effectively save cleaning water.
[0014] In addition, a drying fan is connected to the air supply pipe of the drying tube, allowing the high-temperature airflow from the drying fan to enter the interior of the inner drying tube. The airflow is then directed towards the inner wall of the crucible through an oblique air outlet, separating the water flow in the inner wall of the crucible. As the rotary drive unit drives the crucible clamp to rotate, the crucible clamp forms a rolling connection with the quartz crucible, adapting to the rotation of the crucible. With the rotation of the quartz crucible, the inner wall of the crucible circulates close to the inner drying tube for drying, improving the drying efficiency of the crucible.

[0028] 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.
[0029] Example 1: Please refer to Figures 1 to 8 :
[0030] This utility model discloses a quartz crucible cleaning and drying device, comprising: a crucible conveyor table 1, which is a roller conveyor frame; a conveyor base 2 fixedly connected to the bottom of the crucible conveyor table 1; a lifting drive component 3 fixedly connected to the front and rear of the conveyor base 2 by screws; a lifting screw 4 fixedly connected to the upper end of the rotating shaft of the lifting drive component 3; the upper end of the lifting screw 4 rotatably connected to the lower surface of the crucible conveyor table 1; a clamping push cylinder 5 fixedly connected to the front and rear of the crucible conveyor table 1; a crucible clamping frame 6 fixedly connected to the outer end of the push rod of the clamping push cylinder 5; the crucible clamping frame 6 movably connected to the front and rear walls of the crucible conveyor table 1; and a cleaning inner spray slidably connected to the bottom of the crucible conveyor table 1. The crucible conveying platform 1 has a conveying platform side guide 101 through the front and rear walls, which is slidably connected to the crucible clamping frame 6. The bottom of the crucible conveying platform 1 has a conveying platform vertical guide 102 through the longitudinal direction. The front conveying platform vertical guide 102 is slidably connected to the cleaning inner spray pipe 7, and the rear conveying platform vertical guide 102 is slidably connected to the inner drying pipe 8. The sliding connection between the conveying platform side guide 101 and the crucible clamping frame 6 serves as a guide, enabling the horizontal advancement of the two crucible clamping frames 6. The sliding connection between the conveying platform vertical guide 102 and the cleaning inner spray pipe 7 and the inner drying pipe 8 also serves as a guide, enabling the cleaning inner spray pipe 7 and the inner drying pipe 8 to rise and fall vertically in a straight line.
[0031] In this embodiment, two crucible clamps 601 are rotatably connected to the end of the crucible clamping frame 6. The axis of the crucible clamps 601 is perpendicular to the upper surface of the crucible conveying platform 1. A rotary drive 602 is fixedly connected to the upper surface of the right end support of the rear crucible clamping frame 6 by screws. The rotating shaft of the rotary drive 602 is fixedly connected to the support shaft of the right end crucible clamp 601. When the quartz crucible is conveyed to the set area, the two clamping push cylinders 5 pull the two crucible clamping frames 6 towards the center of the crucible conveying platform 1, causing the crucible clamps 601 to move towards the center of the crucible conveying platform 1 and contact the outer surface of the quartz crucible to form a rolling connection, thus positioning the quartz crucible. As the rotary drive 602 drives the crucible clamps 601 to rotate, the crucible clamps 601 and the quartz crucible form a rolling connection, adapting to the rotation of the crucible. As the quartz crucible rotates, the inner wall of the crucible circulates close to the inner cleaning spray pipe 7 or the inner drying pipe 8 for rinsing and drying.
[0032] In this embodiment, the cleaning inner nozzle 7 has an "L" shaped structure. The bottom of the cleaning inner nozzle 7 is connected to a nozzle lifting push seat 701 by welding. A nozzle spiral push hole 702 is longitudinally opened through the middle of the nozzle lifting push seat 701. The nozzle spiral push hole 702 is spirally connected to the lifting screw 4 located in front. The lower end of the cleaning inner nozzle 7 is fixedly connected to a nozzle water supply pipe 704. An oblique spray hole 703 is opened through the outer pipe wall of the cleaning inner nozzle 7. The oblique spray hole 703 is opened at an angle. The "L" shaped cleaning inner nozzle 7 can better fit close to the inner wall of the crucible. The obliquely set oblique spray hole 703 can improve the concentration of water flow, reduce the dispersion of water flow, and increase the scouring force of water flow on the inner wall of the crucible.
[0033] In Example 2, based on Example 1, a drying tube pusher 801 is welded to the bottom of the inner drying tube 8, and a spiral pushing hole 802 is opened through the center of the drying tube pusher 801; a drying tube air supply pipe 804 is fixedly connected to the lower end of the inner drying tube 8; the inner drying tube 8 has an "L" shaped structure, and an oblique air port 803 is opened on the tube wall of the inner drying tube 8, which is opened at an angle; a drying fan is connected to the drying tube air supply pipe 804, so that the high-temperature airflow in the drying fan enters the drying tube. The water enters the inner drying tube 8 and is blown towards the inner wall of the crucible through the inclined air port 803. The water flow in the inner wall of the crucible is separated by the airflow. As the rotary drive 602 drives the crucible clamp 601 to rotate, the crucible clamp 601 forms a rolling connection with the quartz crucible, adapting to the rotation of the crucible. As the quartz crucible rotates, the inner wall of the crucible circulates close to the inner drying tube 8 for drying, improving the drying efficiency of the crucible. The "L"-shaped inner drying tube 8 can better fit close to the inner wall of the crucible, improving the drying effect.
[0034] The working principle of this embodiment is as follows: First, the quartz crucible is placed upside down at the center of the upper surface of the crucible conveyor table 1. The quartz crucible is conveyed through the crucible conveyor table 1. When the quartz crucible is conveyed to the set area, the two clamping push cylinders 5 pull the two crucible clamping frames 6 towards the center of the crucible conveyor table 1, so that the crucible clamping cylinder 601 moves towards the center of the crucible conveyor table 1 and contacts the outer surface of the quartz crucible to form a rolling connection, thereby positioning the quartz crucible. The lifting drive component 3 drives the lifting... The lowering screw 4 rotates, and the spiral drive formed by the lifting screw 4, the nozzle spiral push hole 702, and the drying tube spiral push hole 802 pushes the cleaning inner nozzle 7 and the inner drying tube 8 upward and inserts them into the quartz crucible. This brings the "L"-shaped cleaning inner nozzle 7 and the inner drying tube 8 close to the inner wall of the quartz crucible. The cleaning inner nozzle 7 is connected to water pressure through the nozzle water supply pipe 704, and the water flow is sprayed obliquely through the nozzle spiral push hole 702 onto the inner wall of the quartz crucible, rinsing the inner wall of the quartz crucible. As the water flows back... The drive unit 602 drives the crucible clamp 601 to rotate, forming a rolling connection between the crucible clamp 601 and the quartz crucible to adapt to the crucible's rotation. As the quartz crucible rotates, the inner wall of the crucible circulates close to the inner cleaning spray pipe 7 for rinsing. After rinsing, a drying fan is connected externally through the drying pipe air supply pipe 804. The drying fan is turned on, allowing the high-temperature airflow in the drying fan to enter the inner drying pipe 8 and be blown towards the inner wall of the crucible through the inclined air port 803, thus dispersing the water in the inner wall of the crucible through the airflow. Separation occurs as the rotary drive 602 drives the crucible clamp 601 to rotate, forming a rolling connection between the crucible clamp 601 and the quartz crucible. This allows the crucible to rotate, and as the quartz crucible rotates, the inner wall of the crucible circulates closer to the inner drying tube 8 for drying. After drying, the two lifting drive components 3 are controlled to rotate, causing the inner cleaning spray pipe 7 and the inner drying tube 8 to retract downwards. The clamping push cylinder 5 pushes the two crucible clamping frames 6 outwards to reset, allowing the quartz crucible to continue to be conveyed above the crucible conveying table 1.
