Description

Technical Field

[0001] The utility model belongs to the fields of photovoltaics and semiconductors, and in particular relates to a fully automatic sand-feeding and molding system for a quartz crucible. Background Art

[0002] Quartz crucible is a sub-product of quartz glass products. It is made of high-purity quartz sand through mold shaping and high-temperature production using the electric arc method. It has the characteristics of high temperature resistance, long service life, and high purity. Quartz crucible is mainly used as an auxiliary consumable for drawing high-purity single crystal silicon rods for semiconductors. It is a key disposable consumable for holding molten silicon liquid during the drawing process of single crystal silicon rods. According to the downstream application scenarios of single crystal silicon rods, quartz crucibles can be divided into quartz crucibles for semiconductor single crystal silicon growth (semiconductor quartz crucibles and photovoltaic single crystal silicon growth quartz crucibles). In recent years, with the vigorous development of the photovoltaic and semiconductor industries, the demand for quartz crucibles has also increased year by year, and at the same time, higher requirements have been placed on the quality of quartz crucibles and their production processes.

[0003] Quartz crucibles need to be stacked with different qualities of quartz sand in each layer under high temperature. The quality of the added quartz sand also varies, and the location and stacking method of the added quartz sand will also vary due to the different shapes of the inner wall and bottom of the quartz crucible. Due to this complex process requirement, the existing quartz crucible production method on the market is generally purely manual.

[0004] Workers work continuously and with high concentration in a high-temperature environment to prevent processing errors, environmental impurities and other problems. For example, if impurities fall into the crucible during processing or the thickness is uneven during the stacking process, the entire quartz crucible will become waste. The current market price of quartz sand is expensive, and the scrap rate increases, which in turn increases the cost of the entire quartz crucible and cannot meet the market's positioning requirements for quartz crucibles.

[0005] However, if the existing mechanical structures on the market are used for assembly, they cannot meet the changing process requirements during the automatic processing of quartz crucibles. Therefore, how to design an automated system equipment that can also process qualified quartz crucibles, and whether this involves improvements to traditional manual processing technology, are issues that need to be studied urgently.

A person skilled in the art will be able to understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0100] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0101] A specific method for fully automatic sanding and forming a quartz crucible is implemented, and the steps include:

[0102] The material is automatically thrown into the quartz crucible melting furnace mold 1 by using the quartz crucible automatic feeding and shape and size control growth equipment 3;

[0103] The quartz crucible automatic forming control device 4 cooperates with the quartz crucible melting furnace mold 1 to scrape the material thrown into the quartz crucible melting furnace mold 1 so that it accumulates inside the quartz crucible melting furnace mold 1 to form a quartz crucible prototype;

[0104] The quartz crucible is formed by stacking quartz sand of at least two qualities. At least the first time the quartz crucible automatically feeds and the shape and size control growth device 3 throws the material, it throws the material only to the inner wall of the quartz crucible melting furnace mold 1. After that, the quartz crucible automatically feeds and the shape and size control growth device 3 performs the material throwing work according to the quartz sand of different qualities. At least the last time the quartz crucible automatically feeds and the shape and size control growth device 3 throws the material, it throws the material to the inner wall of the quartz crucible melting furnace mold 1 and makes the material accumulate on the inner wall. After that, the quartz crucible automatically feeds and the shape and size control growth device 3 throws the material to the inner bottom of the quartz crucible melting furnace mold 1 and makes the material accumulate on the inner bottom.

[0105] Generally, materials are stacked in the order of secondary materials, outer layer materials, middle layer materials, and inner layer materials; one or two materials may be missing, depending on the process.

[0106] When the secondary material and the outer layer material are stacked, the inner wall of the quartz crucible melting furnace mold 1 is scraped. When the middle layer material and the inner layer material are stacked, the inner wall of the quartz crucible melting furnace mold 1 is scraped first, and then the inner bottom of the quartz crucible melting furnace mold 1 is scraped to complete the formation of the quartz crucible.

[0107] When material has accumulated on the inner bottom of the quartz crucible melting furnace mold 1, the quartz crucible automatic feeding and shape and size control growth device 3 stops scraping the inner bottom of the quartz crucible melting furnace mold 1, and then the quartz crucible automatic shaping control device 4 continues to scrape the inner bottom of the quartz crucible melting furnace mold 1 for at least one round. This ensures that no waste is generated and that all materials are accumulated in the corresponding positions.

[0108] The quartz crucible automatic feeding and shape and size control growth device 3 is placed in the quartz crucible melting furnace mold 1, and the material is thrown from bottom to top, which conforms to the inertia of material gravity and stacking inertia, so that the material can be firmly accumulated inside the quartz crucible melting furnace mold 1.

[0109] The speed at which the quartz crucible automatic feeding and shape and size control growth device 3 throws the material to the inner wall of the quartz crucible melting furnace mold 1 is greater than the speed at which the material is thrown to the inner bottom of the quartz crucible melting furnace mold 1 .

[0110] The quartz crucible automatic feeding and shape and size control growth equipment 3 is placed in the quartz crucible melting furnace mold 1, and the material throwing outlet is perpendicular to the inner wall of the quartz crucible melting furnace mold 1. This better ensures that the material is thrown into the interior of the quartz crucible melting furnace mold 1 and is convenient for stacking, and also reduces the material deposition problem caused by manual tilting and throwing, which has occupied space.

[0111] The scraper assembly used by the automatic quartz crucible shaping control device 4 for scraping materials is replaced based on the quality of the material being scraped. The feeding hopper 3621 used to hold the material to be discarded in the automatic quartz crucible feeding and shape and size control growth device 3 is also replaced based on the quality of the material. Both functions are designed to prevent cross-contamination and ensure material cleanliness during quartz crucible processing. The scraper assembly maintains a vertical horizontal position while operating the quartz crucible melting furnace mold 1.

[0112] The quartz crucible automatic feeding and shape and size control growth device 3 is close to the inner wall of the quartz crucible melting furnace mold 1 when throwing the material to the inner wall of the quartz crucible melting furnace mold 1;

[0113] When the quartz crucible automatic feeding and shape and size control growth device 3 throws the material to the inner bottom of the quartz crucible melting furnace mold 1, it is close to the middle position of the inner bottom of the quartz crucible melting furnace mold 1. This makes it convenient to throw the material to the corresponding position more quickly.

[0114] It also includes an automatic classification and transportation device 2 for quartz crucible sand, which automatically feeds the automatic feeding and shape and size control growth device 3 for quartz crucible. When the automatic classification and transportation device 2 for quartz crucible sand feeds different qualities of materials to the automatic feeding and shape and size control growth device 3 for quartz crucible, different sand material barrels 23 are used to weigh the materials and drop them into the automatic feeding and shape and size control growth device 3 for quartz crucible; the automatic classification and transportation device 2 for quartz crucible sand can be lowered to the operating position, and the sand material barrel 23 is fed at the operating position.

[0115] The device also includes a quartz sand processing flying material collecting device 5 , which can automatically collect the waste thrown out of the quartz crucible melting furnace mold 1 .

[0116] If all the above equipment are included, the specific process steps include:

[0117] The automatic classification and handling equipment 2 for quartz crucible sand classifies and loads materials of different qualities. The automatic feeding and shape and size control growth equipment 3 for quartz crucible is fed with materials of one quality each time. The automatic feeding and shape and size control growth equipment 3 for quartz crucible weighs the materials to determine their weight and then throws the materials into the quartz crucible melting furnace mold 1. The automatic forming control equipment 4 for quartz crucible is started and scrapes the materials thrown into the quartz crucible melting furnace mold 1, so that the materials are accumulated in the corresponding positions of the quartz crucible melting furnace mold 1.

[0118] During the scraping process of the same material, when the inner bottom of the quartz crucible melting furnace mold 1 needs to be stacked, the inner wall of the quartz crucible melting furnace mold 1 is scraped first, and then the inner bottom of the quartz crucible melting furnace mold 1 is scraped;

[0119] After the quartz crucible automatic feeding and shape and size control growth device 3 stops throwing materials, the quartz crucible automatic shaping control device 4 continues to act on the corresponding position of the quartz crucible melting furnace mold 1 for at least one circle. At this time, the quartz crucible automatic feeding and shape and size control growth device 3 moves out of the quartz crucible melting furnace mold 1, and then receives the quartz crucible sand automatic classification and transportation device 2 to load other materials;

[0120] During the movement of the quartz crucible automatic forming control device 4, the quartz sand processing flying material collecting device 5 collects the materials splashed out of the quartz crucible melting furnace mold 1;

[0121] In response to scraping materials of different qualities, the quartz crucible automatic forming control device 4 replaces the scraper assembly for scraping the materials.

[0122] The above process requirements can also be separately required on each corresponding equipment, which can improve the automation and cleanliness requirements of quartz crucible processing and improve the quality of processed quartz crucibles.

[0123] In addition to the above process methods, a fully automatic sand-loading and molding system for quartz crucibles has also been designed. This system can use the above process methods and can also be programmed separately for automated processing.

[0124] like Figure 1 As shown, a fully automatic sand-feeding and molding system for a quartz crucible includes a quartz crucible automatic molding control device 4 and a quartz crucible automatic feeding and shape and size control growth device 3;

[0125] The quartz crucible automatic forming control device 4 cooperates with the quartz crucible melting furnace mold 1 to scrape the material and make the material accumulate inside the quartz crucible melting furnace mold 1;

[0126] The quartz crucible automatic feeding and shape and size control growth device 3 enters the quartz crucible melting furnace mold 1 and throws materials of different qualities into the quartz crucible melting furnace mold 1 according to process requirements. It cooperates with the quartz crucible automatic forming control device 4 to make the thrown materials accumulate inside the quartz crucible melting furnace mold 1 to form a quartz crucible prototype.

[0127] It also includes an automatic classification and transportation device 2 for quartz crucible sand, which is used to load the required materials into the automatic feeding and shape and size control growth device 3 for quartz crucible;

[0128] A quartz crucible automatic forming control device 4 is provided on one side of the quartz crucible melting furnace mold 1, and a quartz crucible automatic feeding and shape and size control growth device 3 is provided on the other side thereof.

The quartz sand processing flying material collection device 5 is on the same side as the quartz crucible automatic feeding and shape and size control growth device 3, and is arranged between the quartz crucible automatic feeding and shape and size control production equipment and the quartz crucible sand automatic classification and transportation equipment 2.

[0130] The sand material barrel 23 in the automatic classification and transportation device 2 for quartz crucible sand can be lowered to the operating position for adding materials, and can be raised and rotated to the top of the automatic feeding and shape and size control growth device 3 for quartz crucible. The sand material barrel 23 is used to carry the materials that fall into the automatic feeding and shape and size control growth device 3 for quartz crucible;

[0131] The discharge point of the sand barrel 23 is connected to the outside through the classification barrel discharge pipe 246 and is arranged in conjunction with the quartz crucible automatic feeding and shape and size control growth equipment 3. The classification barrel opening and closing valve 244 includes a baffle 2441 and a baffle 2441 movement mechanism. The baffle 2441 movement mechanism causes the baffle 2441 to be displaced relative to the nozzle of the classification barrel discharge pipe 246. One extreme position of the displacement of the baffle 2441 is completely away from the nozzle of the classification barrel discharge pipe 246, and the other extreme position is completely covering the nozzle of the classification barrel discharge pipe 246.

[0132] It also includes a classification barrel vibrator 243 and a classification barrel blowing component;

[0133] The classification barrel vibrator 243 is installed at the discharge of the sand barrel 23 and is used to generate vibration at the discharge of the sand barrel 23;

[0134] The blowing component of the classification barrel includes a blowing pipe and an air generator. One end of the blowing pipe is connected to the air generator, and the other end is connected to the discharge point of the sand barrel 23.

[0135] The quartz crucible automatic feeding and shape and size control growth device 3 includes a feeding hopper 3621 for weighing and storing materials. The materials in the feeding hopper 3621 fall onto a throwing plate 3638 and are thrown out by the rotational force provided by the motor 3631 of the throwing plate 3638. The feeding hopper 3621 can be raised and rotated to the position of the automatic classification and transportation device 2 for quartz crucible sand, and the throwing plate 3638 can be rotated and lowered into the quartz crucible melting furnace mold 1.

[0136] The upper baffle plate 2441 of the throwing plate 3638 is also provided above the throwing plate 3638. A throwing space is formed between the throwing plate 3638 and the upper baffle plate 2441 of the throwing plate 3638. The material in the feeding bin 3621 is thrown out through the throwing space via the upper baffle plate 2441 of the throwing plate 3638.

[0137] The spinner 3638 is partitioned to form a plurality of independent spinner 3638 troughs, and the material in the feeding bin 3621 is connected to the spinner 3638 trough;

[0138] The material trough of the spinning plate 3638 is fan-shaped and gradually radiates outward from the center of the spinning plate 3638;

[0139] A feeding bin 3621 air blowing pipe is also provided, through which gas is blown into the feeding bin 3621;

[0140] The feeding silo 3621 is an open funnel-shaped silo, which is covered with a feeding silo cover 3621, and the feeding silo cover 3621 is opened with a feeding silo cover 3621;

[0141] The feeding silo 3621 has a cover plate 3624 on its cover, and the edge of the cover of the feeding silo 3621 has a protruding enclosure, and the silo cover is closed and covered above the enclosure. The cover plate 3624 can rotate relative to the cover of the feeding silo 3621, and the blowing pipe of the feeding silo 3621 is installed on the surface of the cover plate 3624 facing the feeding silo 3621;

[0142] It also includes a feeding pipe 3633 and a feeding valve blowing pipe 3653. The outlet of the feeding bin 3621 is connected to the feeding pipe 3633, and the material falls into the trough of the spinning plate 3638 through the feeding pipe 3633.

[0143] The outlet of the feeding valve blowing pipe 3653 is connected to the inlet of the feeding supply pipe 3633 or the outlet of the feeding bin 3621, so as to blow gas into the corresponding pipeline.

[0144] The quartz crucible automatic forming control device 4 includes a scraper assembly for scraping the material in the quartz crucible melting furnace mold 1 so that the material accumulates inside the quartz crucible melting furnace mold 1;

[0145] The scraper assembly can rise and rotate away from above the quartz crucible melting furnace mold 1, and can also rotate and descend into the quartz crucible melting furnace mold 1; the scraper assembly can also perform translational motion relative to the position where the inner wall or inner bottom of the quartz crucible melting furnace mold 1 is located;

[0146] Each scraper assembly includes a formed scraper vertical portion 411 and a formed scraper horizontal portion 412, wherein the formed scraper vertical portion 411 and the formed scraper horizontal portion 412 form an "L"-shaped scraper body, wherein the connection point of the formed scraper vertical portion 411 and the formed scraper horizontal portion 412 is the forming end point, and the end point of the formed scraper horizontal portion 412 away from the formed scraper vertical portion 411 is the forming starting point, and the height of the forming starting point from the horizontal plane gradually increases to the forming end point;

[0147] The scraper assembly also includes a formed scraper side scraper portion 413, which is installed on the side of the "L"-shaped scraper body. The working surface of the formed scraper side scraper portion 413 cooperates with the side wall of the mold that carries the material to be scraped, and the working surface of the "L"-shaped scraper body cooperates with the inner bottom of the mold that carries the material to be scraped.

[0148] The specific practical structures of the quartz crucible automatic forming control equipment 4, the quartz crucible automatic feeding and shape and size control growth equipment 3, the quartz crucible sand automatic classification and transportation equipment 2, and the quartz sand processing flying material collection equipment 5 also have many special designs. At the same time, the structure for the above-mentioned operation displacement is also specifically described in the embodiments.

[0149] An embodiment of a separate structural design description of an automatic classification and handling device for semiconductor and solar quartz crucible sand 2:

[0150] like Figure 2-1 and 2-2 As shown, an automatic sand sorting and transporting device 2 for semiconductor and solar quartz crucibles includes a sorting lifting mechanism 21, a sorting rotating mechanism 22 and at least two sand barrels 23;

[0151] The classification lifting mechanism 21 and the classification rotating mechanism 22 work together to enable the sand barrel 23 to rotate and lift at a preset origin;

[0152] Each discharge port of the sand material barrel 23 is connected to a useful sand dividing assembly 24 , and the sand dividing assembly 24 includes a classification barrel opening and closing valve 244 for controlling the opening and closing degree of the discharge port of the sand material barrel 23 .

[0153] The sand barrel 23 needs to be moved to the vicinity of the quartz crucible melting furnace mold 1 through the classification rotation mechanism 22 and the classification lifting mechanism 21 to facilitate blanking or loading. Generally, it will go through a weighing process before entering the mold, so a quartz crucible automatic feeding and shape and size control growth device may be added to accurately measure the weight and speed of the feeding. Of course, the patented device can also be used to directly add materials to the quartz crucible melting furnace mold 1 and select according to processing requirements.

[0154] The production of quartz crucibles is generally divided into different levels, and the added materials generally include secondary materials, outer layer materials, middle layer materials, inner layer materials, and fine powder materials; therefore, the sand barrel 23 can be set in quantity according to the type of material, and the classification rotating structure can be used to determine which type of material to be dropped.

[0155] Due to the requirement of automated classification and unloading, as long as the sand material barrel 23 carrying the material can be rotated and lifted and lowered, the requirement can be met. Therefore, the classification rotation mechanism 22 and the classification lifting mechanism 21 can be divided into two installation modes. One is that the classification lifting mechanism 21 carries the sand material barrel 23 to be lifted and lowered and is driven to rotate by the classification rotation mechanism 22. The other is that the classification lifting mechanism 21 drives the classification rotation mechanism 22 to be lifted and lowered. The sand material barrel 23 is connected to the classification rotation mechanism 22, and the sand material barrel 23 can be rotated according to the preset origin.

[0156] The specific installation structure is as follows:

[0157] 1. The classification rotating mechanism 22 is connected to the classification lifting mechanism 21, and the sand barrel 23 is connected to the classification rotating mechanism 22 and rotates relative to the classification lifting mechanism 21 through the classification rotating mechanism 22;

[0158] Second, the classification lifting mechanism 21 is connected to the classification rotating mechanism 22, and the sand material barrel 23 is connected to the classification lifting mechanism 21. The classification rotating mechanism 22 makes the classification lifting mechanism 21 rotate around a preset origin, and the sand material barrel 23 moves with the classification lifting mechanism 21;

[0159] The classification lifting mechanism 21 enables the sand barrel 23 to move up and down relative to a preset origin.

[0160] Figures 2-5 to 2-8 The material distribution rotating mechanism is shown to be installed on the material distribution lifting mechanism, and the sand material barrel 23 is installed on the material distribution rotating mechanism;

[0161] The classification rotation mechanism 22 includes a classification rotation servo motor 221 and a classification rotation external tooth bearing 223; the classification rotation external tooth bearing 223 has an outer ring with a circle of meshing teeth, and the inner ring is fixed to the classification rotation fixed seat 225. The output end of the classification rotation servo motor 221 is connected to the classification rotation drive teeth 224, and the classification rotation drive teeth 224 are meshed with the outer ring of the classification rotation external tooth bearing 223;

[0162] The sand material barrel 23 is connected to the outer ring of the classification rotation external gear bearing 223, and the classification rotation fixed seat 225 is connected to the classification lifting mechanism 21;

[0163] Furthermore, a classification rotation limiter 222 is provided on the outer ring of the classification rotation external gear bearing 223 to limit the rotation position of the classification rotation external gear bearing 223. This can be achieved by using a limit sensor or a mechanical blocking structure. When the predetermined position of the sand material barrel 23 is set, the classification rotation limiter 222 can prevent the sand material barrel 23 from rotating excessively and also limit its corresponding position. Of course, the main function of the sand material barrel 23 reaching the fixed position is achieved by controlling the classification rotation servo motor 221.

[0164] The classification lifting mechanism 21 includes a classification lifting bracket 219, a classification lifting servo motor 214 and a classification lifting driving rack 213;

[0165] The classification lifting drive rack 213 is fixed on the classification lifting bracket 219, the output end of the classification lifting servo motor 214 is connected to the classification lifting gear, the classification lifting gear is engaged with the classification lifting rack, and the classification lifting servo motor 214 is fixed on the classification lifting seat;

[0166] A classification rotating mechanism 22 is installed on the classification lifting seat, and a sand material cylinder 23 is connected to the classification rotating mechanism 22.

[0167] When the classification lifting mechanism 21 rotates with the classification rotating mechanism 22, the specific connection method is as follows:

[0168] The classification lifting mechanism 21 is connected to the outer ring of the classification rotating external tooth bearing 223 , the classification rotating fixed seat 225 is fixed at a preset position, and the sand barrel 23 is connected to the classification lifting mechanism 21 in a liftable manner.

[0169] The sand material cylinder 23 is installed on the classification lifting seat, and the classification lifting bracket 219 is installed on the classification rotating mechanism 22.

[0170] Regardless of the connection method used by the classification lifting mechanism 21 and the classification rotating mechanism 22, classification V-shaped rollers 215 are provided on both sides of the classification lifting seat, and classification V-shaped guide rails 216 are provided on both sides of the classification lifting bracket 219. The classification V-shaped rollers 215 are rollingly arranged in the classification V-shaped guide rails 216. The coordinated rolling of the classification V-shaped guide rails 216 and the classification V-shaped rollers 215 can play a guiding role for the classification lifting mechanism 21, thereby improving the stability of the lifting. At the same time, the V-shaped connection can effectively reduce the contamination of the falling materials by impurities and dust, thereby ensuring that the machine can still be used and operated normally in a non-high cleanliness environment.

[0171] Furthermore, the classification lifting bracket 219 is provided with a classification lifting locking hole 218, and the classification lifting seat is also provided with a classification lifting limit locking cylinder 217. The output end of the classification lifting limit locking cylinder 217 is connected to a locking member, which is plugged into the classification lifting locking hole 218. When the classification lifting mechanism 21 rises to a preset position, the classification lifting limit locking cylinder 217 moves and causes the locking member to be inserted into the corresponding classification lifting locking hole 218, thereby fixing the position and improving the safety of the entire classification lifting mechanism 21. Therefore, multiple classification lifting locking holes 218 can be provided on the classification lifting bracket 219 to meet different travel requirements.

[0172] The classification lifting bracket 219 is fixed at a preset position by a classification lifting base 25, and a classification column auxiliary support leg 26 is added to the lower side of the classification lifting bracket 219 to form the classification lifting bracket 219 into a stable triangle shape and fix it at the preset position.

[0173] A classification lifting anti-fall device 212 is also provided above the classification lifting bracket 219 , and the classification lifting anti-fall device 212 is equivalent to a structure for preventing falling in an elevator.

[0174] like Figure 2-3 、 2-4 2-9 is a schematic diagram showing the cooperation between the sand barrel 23 and the classification barrel opening and closing valve 244. The sand barrel 23 can be connected to the outside through the classification barrel discharge pipe 246, or it can be directly connected to the outside.

[0175] The classification barrel opening and closing valve 244 is used to control the opening and closing degree of the discharge of the sand barrel 23. The classification barrel opening and closing valve 244 here controls the opening and closing degree of the discharge of the sand barrel 23. There are many options for the valve body. You can choose a valve body with only an opening and closing function (only used to control the discharge of materials of different masses and also to control the weight of the discharged materials). You can also choose a valve body with multiple gear openings. This valve body can control the size of the outlet of the discharge of the sand barrel 23 to the outside, so that the discharge speed can be further controlled. The specific valve body selected on the market can be a gate valve, a stop valve, a butterfly valve, a ball valve, etc.

[0176] In order to better match the size and position of the sand barrel 23, this patent has innovated a valve body structure, which is as follows:

[0177] The discharge point of the sand barrel 23 is connected to the outside through the classification barrel discharge pipe 246. The classification barrel opening and closing valve 244 includes a baffle 2441 and a baffle 2441 movement mechanism. The baffle 2441 movement mechanism is used to displace the baffle 2441 relative to the pipe mouth of the classification barrel discharge pipe 246. One extreme position of the displacement of the baffle 2441 is completely away from the pipe mouth of the classification barrel discharge pipe 246, and the other extreme position is to completely cover the pipe mouth of the classification barrel discharge pipe.

[0178] Alternatively, a graduation groove is provided in the middle of the discharge pipe 246 of the classification barrel, and the graduation groove is adapted to the baffle 2441;

[0179] The baffle 2441 is displaced relative to the indexing groove by the movement mechanism of the baffle 2441. One extreme position of the displacement of the baffle 2441 is to be completely away from the indexing groove and to allow the nozzle of the discharge pipe 246 of the classification barrel to be connected to the outside world. The other extreme position is to be completely inserted into the indexing groove and to isolate the discharge pipe 246 of the classification barrel from the outside world.

[0180] The baffle 2441 and the outer portion of the indexing groove are covered in the valve housing of the classification barrel opening and closing valve 244; the classification barrel opening and closing valve 244 is installed on the classification barrel discharge mounting plate 247;

[0181] The sorting barrel discharge mounting plate 247 is provided with a sorting barrel air hole 245. An air generator is connected to the sorting barrel discharge pipe 246 through the sorting barrel air hole 245. The air blown by the air generator can act on the interior of the sorting barrel discharge pipe 246. The air generator can also be directly connected to the sorting barrel discharge point through an air pipe. The air generator blows air into the sorting barrel discharge pipe 246 or the outlet of the sand barrel 23. Both the nozzle of the sorting barrel discharge pipe 246 and the outlet of the sand barrel 23 can be referred to as the blanking outlet, that is, the portion that communicates with the external environment. The sorting barrel discharge pipe 246 or the outlet of the sand barrel 23 are both designed as funnels to facilitate discharge.

[0182] The movement mechanism of the baffle 2441 can be a servo electric cylinder or a pneumatic cylinder, as long as the running trajectory can be controlled so that the baffle 2441 can stay in the preset position at any time as needed.

[0183] Furthermore, the sand-classifying component 24 further includes a classifying barrel vibrator 243 and a classifying barrel blowing component;

[0184] The classification barrel vibrator 243 is installed at the discharge of the sand barrel 23 and is used to generate vibration at the discharge of the sand barrel 23;

[0185] The blowing component of the classification barrel includes a blowing pipe and an air generator. One end of the blowing pipe is connected to the air generator, and the other end is connected to the discharge point of the sand barrel 23.

[0186] The classification valve assembly protective cover 241 is also included. The classification valve assembly protective cover 241 is fixed at the discharge of the classification barrel and covers the classification barrel opening and closing valve 244, the classification barrel vibrator 243, and the air blowing pipeline in the classification barrel air blowing component. It can prevent contaminants generated by the moving components from falling into the quartz sand.

[0187] Furthermore, the sand barrel 23, the classification barrel opening and closing valve 244, and the classification barrel discharge pipe 246 are all made of 304 grade or above stainless steel to prevent material contamination caused by rust, or quartz sand material, even if there are tiny impurities falling, it will not cause material contamination.

[0188] Working principle: (Take the classification rotating mechanism 22 installed on the classification lifting mechanism 21 as an example)

[0189] A plurality of sand material cylinders 23 are provided as needed. Here, five sand material cylinders 23 are taken as an example. The five sand material cylinders 23 are mounted together through a classification mounting plate. The classification mounting plate is mounted on the classification rotating mechanism 22, specifically, on the outer shaft of the classification rotating external tooth bearing 223.

[0190] The classification rotating fixed seat 225 in the classification rotating mechanism 22 is connected to the classification lifting seat, and the classification lifting seat is fixed to the classification lifting servo motor 214. Through the rotation of the classification lifting servo motor 214, the classification rotating mechanism 22 can move vertically on the classification lifting bracket 219;

[0191] First, the sand barrels 23 are lowered to a position accessible to humans or machines through the classification lifting mechanism 21. After quartz sand of corresponding quality is added to each sand barrel 23 manually or by machine, the sand barrels 23 are raised to a preset position. Then, the classification rotation servo motor 221 in the classification rotation mechanism 22 is started, causing the sand barrels 23 to rotate. The classification rotation servo motor 221 controls which sand barrel 23 needs to be rotated to the corresponding position.

[0192] Then, the classification barrel opening and closing valve 244 is started to control the opening and closing of the valve body to coordinate with the blanking of the sand barrel 23. If the innovative valve body of this patent is used, the size of the blanking opening can be controlled by controlling the movement mechanism of the baffle 2441, thereby controlling the blanking speed;

[0193] During this period, the classification barrel vibrator 243 and the air generator are turned on so that there is always vibration and air blown out at the blanking position to prevent the material station from adhering to the blanking outlet.

[0194] (1) The automatic sorting and handling equipment for semiconductor and solar quartz crucible sand is equipped with multiple rotatable and elevating sand barrels, which can meet the needs of adding materials of different qualities. At the same time, the purpose of automatically adding sand is achieved through the mechanical structure. Combined with the cleanliness requirements of the quartz crucible during the processing, different sand barrels can reduce the contamination between materials of different qualities. The use of the classification barrel opening and closing valve to control the amount of sand barrel falling can also meet the requirements of accurately controlling the amount of sand falling. Not only does the mechanical design realize the automatic sorting of quartz sand, but it also replaces the problems of low manual efficiency and the inability to ensure cleanliness and consistency.

[0195] (2) The structural design of the opening and closing valve of the classification barrel of the automatic classification and handling equipment for semiconductor and solar quartz crucible sand can meet the quantitative requirements of quartz sand blanking, and can control the opening and closing degree of blanking, thereby controlling the blanking speed and meeting the subsequent requirements for the quartz crucible processing technology.

[0196] (3) The vibrator and blowing parts of the classification barrel of the automatic classification and handling equipment for semiconductor and solar quartz crucible sand can further improve the accuracy and cleanliness requirements of the blanking. Since quartz sand has a certain viscosity, it may "hang on the wall" during the blanking process, and the smoothness of the blanking can be improved by vibration; the added blowing part can assist the vibration to ensure the smoothness of the blanking, and at the same time improve the cleanliness of the blanking, and will not cause the quartz sand added to the sand barrel later to mix with the previous quartz sand, thereby improving the cleanliness and ensuring the quality of subsequent quartz crucible processing.

[0197] (4) The protective cover of the classification valve group of the automatic classification and handling equipment for semiconductor and solar quartz crucible sand can wrap the mechanical parts around the blanking position, further ensuring the cleanliness of the quartz sand during the blanking process and meeting the prerequisite requirements for the automated production of quartz crucibles.

[0198] (5) The structural design of the classification rotation mechanism of the automatic classification and transportation equipment for semiconductor and solar quartz crucible sand can not only meet the requirements that the sand barrel can rotate along the preset origin, thereby achieving the purpose of loading materials at one place and unloading materials at another place, avoiding the contamination problem caused by pouring materials into the sand barrel at the unloading position; but also can minimize the coordination of spare parts due to the rotating structural design, avoiding more pollution during the operation of parts.

[0199] (6) The structural design of the classification and lifting mechanism of the automatic classification and handling equipment for semiconductor and solar quartz crucible sand. The structural coordination design avoids the lifting and lowering jamming caused by the excessive weight of the material in the sand barrel, and meets the requirements of lifting stability.

[0202] The feeding and control mechanism 36 includes a feeding silo 3621, a feeding valve assembly for controlling the degree of communication between the material in the feeding silo 3621 and the outside world, and a silo weighing assembly 364 for weighing the material in the feeding silo 3621. The material in the feeding silo 3621 falls into a spinner 3638 through the feeding valve assembly, and the spinner 3638 rotates to spin the material out.

[0203] The feeding rotation mechanism 33 is used to control the feeding and the rotation of the control mechanism 36 at a preset origin;

[0204] The feeding translation mechanism 35 is used to control the feeding and control mechanism 36 to approach or move away from the preset material ejection position;

[0205] The feeding and lifting mechanism 34 is used to control the feeding and the control mechanism 36 to rise or fall relative to the position where the material needs to be thrown away;

[0206] The feeding rotation mechanism 33, the feeding translation mechanism 35 and the feeding lifting mechanism 34 cooperate with each other to make the feeding and control mechanism 36 move relative to the position where the materials need to be thrown away.

[0210] like Figure 3-6 、 3-8 As shown, the feeding valve assembly includes a feeding valve servo electric cylinder 3651 and a feeding valve baffle 3652. The feeding valve baffle 3652 is powered by the feeding valve servo electric cylinder 3651 and moves relative to the outlet of the feeding silo 3621. One extreme position of the displacement of the feeding valve baffle 3652 is completely away from the outlet of the feeding silo 3621, allowing the outlet of the feeding silo 3621 to be connected to the outside world.

[0244] The feeding valve baffle 3652, the throwing plate 3638, and the upper baffle of the throwing plate 3638 in the feeding valve assembly are all made of quartz sand, and other connection and installation methods are adopted to avoid exposing components such as mounting screws to the outside, and try to wrap the components in the cover to reduce the impurities generated by the components and mix with the quartz sand material, thereby causing pollution.

[0245] Working principle:

[0246] The feeding translation mechanism 35 is installed on the operating electric cabinet 32, the feeding translation slider 332, and the feeding lifting mechanism 34 is installed on the outer ring of the feeding rotating turntable bearing 331 with external teeth on the feeding rotating mechanism 33 through the feeding lifting mounting seat 335. The feeding connecting frame 361 is installed on the feeding lifting mounting seat 335 of the feeding lifting mechanism 34.

[0247] The operating electrical cabinet 32 ​​is provided with a feeding operation button 321 for operating the entire device, and is also provided with a feeding display screen 322 for displaying the weighing mass.

[0248] When quartz sand needs to be added to the feeding silo 3621, first withdraw the feeding silo 3621 to an original position, lower the feeding silo 3621 to the bottom, add the material through the cover of the feeding silo 3621, and then rotate the silo cover sealing plate 3624 to cover it.

[0249] The weight of the added material is weighed by the silo weighing component 364 to check whether it meets the weight requirements.

[0250] The feeding bin 3621 is raised and rotated to a position close to the quartz crucible melting furnace mold 1 , and the feeding and control mechanism 36 is moved above the quartz crucible melting furnace mold 1 through the feeding translation mechanism 35 .

[0251] Start the air blowing pipe of the feeding bin 3621 to blow air into the feeding bin 3621 to ensure smooth material discharge;

[0252] The feeding valve baffle 3652 is started, opening the outlet of the feeding bin 3621, allowing the material in the feeding bin 3621 to fall into the feeding pipe 3633, and at the same time, the rotation motor 3631 of the throwing plate 3638 is turned on, causing the throwing plate 3638 to rotate, and the material falls into the throwing plate 3638 and is thrown to the outside by centrifugal force.

[0253] (1) The feeding and control mechanism of the quartz crucible automatic feeding and shape and size control growth equipment can mechanically realize the dropping of the quartz sand material according to the required weight, and through the setting of multiple motion mechanisms, it realizes three-dimensional angle operation, which can meet the position requirements of the feeding of the previous process and the processing and forming of the quartz crucible of the next process, and avoids the processing and forming position of the quartz crucible when feeding into the feeding hopper, and further improves the cleanliness of the quartz sand thrown into the quartz crucible melting furnace mold. At the same time, due to the setting of three-dimensional multi-operation tracks, the mechanical automation of feeding can be realized, the efficiency of quartz crucible production can be improved, manpower can be reduced, and costs can be reduced.

[0254] (2) Automatic feeding of quartz crucible and control of shape and size The design of multiple feeding silos of the growth equipment can meet the feeding requirements of quartz sand of different qualities. Only one machine can meet all the requirements of quartz crucible feeding, which also improves the degree of automation.

[0255] (3) Quartz crucible automatic feeding and shape and size control The silo cover sealing plate of the growth equipment can not only ensure the cleanliness of the material in the feeding silo, but also add a feeding silo air blowing pipe at this position to improve the falling smoothness of the material in the feeding silo and prevent the material from sticking to the feeding silo.

[0256] (4) Automatic feeding and shape and size control of quartz crucibles. The feeding valve assembly of the growth equipment can control the blanking time of the feeding hopper and the blanking speed. This can be achieved by controlling the outlet size of the feeding hopper. This mechanical structure meets the state and speed requirements of quartz sand of different qualities and processes being thrown into the mold, further enhancing the degree of automation of the entire quartz crucible manufacturing process and avoiding excessive human intervention.

[0257] (5) The structure of the disk assembly of the quartz crucible automatic feeding and shape and size control growth equipment can ensure that when the disk is rotating, the pollutants generated by other moving parts will not fall into the disk. At the same time, the material trough formed by the partition can further ensure the running trajectory of the quartz sand thrown out, which is basically in a vertical state with the inner wall of the mold, so that the quartz sand thrown out can be accumulated on the inner wall of the mold, reducing the processing complexity of the subsequent process.

[0258] (6) The combination of various different operating mechanisms of the quartz crucible automatic feeding and shape and size control growth equipment can all achieve the three-dimensional running trajectory requirements, and the specific structural forms of the feeding lifting mechanism, feeding rotating mechanism, and feeding translation mechanism can use the structural form of the existing technology or the structural form protected by this patent. The structural form protected by this patent can make the movement process smoother, with fewer parts exposed to the outside, and improve the cleanliness of the quartz sand discharged.

[0259] An embodiment of a separate structural design description of a quartz crucible automatic forming control device 4:

[0260] like Figure 4-1 As shown, the quartz crucible automatic forming control device 4 cooperates with the quartz crucible melting furnace mold 1 (hereinafter referred to as the mold) to produce and eventually form a prototype quartz crucible.

[0261] like Figure 4-2 As shown, the quartz crucible automatic forming control device 4 includes a forming scraper assembly 41, a forming rotation mechanism 43, a forming translation mechanism 44 and a forming lifting mechanism 45;

[0262] like Figure 4-8 As shown, the forming scraper assembly 41 is used to scrape the material in the mold so that the material accumulates on the mold; according to the various quality requirements of quartz sand, multiple forming scraper assemblies 41 are set, and each forming scraper corresponds to a quality of quartz sand. The multiple forming scraper assemblies 41 can each have an independent motion mechanism, but in order to save space to the maximum extent and operate more accurately, the multiple forming scraper assemblies 41 can be connected at the same forming connection point and rotated by the same forming rotation mechanism 43.

[0263] The scraper assembly includes a formed scraper vertical portion 411 and a formed scraper horizontal portion 412, wherein the formed scraper vertical portion 411 and the formed scraper horizontal portion 412 form an "L"-shaped scraper body. The connection point of the formed scraper vertical portion 411 and the formed scraper horizontal portion 412 is the forming end point, and the end point of the formed scraper horizontal portion 412 away from the formed scraper vertical portion 411 is the forming starting point. The height of the forming starting point from the horizontal plane gradually increases to the forming end point.

[0264] The scraper assembly also includes a formed scraper side scraper portion 413, which is installed on the side of the "L"-shaped scraper body. The working surface of the formed scraper side scraper portion 413 cooperates with the side wall of the mold that carries the material to be scraped, and the working surface of the "L"-shaped scraper body cooperates with the inner bottom of the mold that carries the material to be scraped.

[0265] The scraper side scraper portion 413 can act on the inner wall of the mold, and the L-shaped scraper body can act on the inner bottom of the mold. The scraper assembly can then satisfy the action relationship on the entire mold, meeting the requirements of automatic processing of quartz crucibles.

[0266] The forming rotation mechanism 43 is used for rotating the forming scraper assembly 41 about a preset origin;

[0267] The shaping translation mechanism 44 is used to move the shaping scraper assembly 41 closer to or farther from a preset position for carrying the material to be scraped;

[0268] The forming lifting mechanism 45 is used to raise or lower the forming scraper assembly 41 relative to the preset position of the material to be scraped;

[0269] The forming rotation mechanism 43 , the forming translation mechanism 44 and the forming lifting mechanism 45 cooperate with each other to cause the forming scraper assembly 41 to move relative to a preset position for carrying the material to be scraped.

[0270] Therefore, there are many options for how to connect and install the forming rotation mechanism 43, the forming translation mechanism 44, and the forming lifting mechanism 45, as long as the scraper assembly can be moved away from or close to the mold, the scraper assembly can be replaced, and the inner wall or inner bottom of the mold can be acted on. The following describes the preferred structures of the three mechanisms respectively, and further describes the preferred connection method.

[0271] like Figure 4-6 As shown, the molding rotating mechanism 43 can be provided with rotational power by a gear meshing mode or by a synchronous belt driven rotation mode. The present patent preferably adopts a gear meshing mode, specifically including a molding rotating base 431 and a molding rotating turntable bearing 432 with external teeth.

[0272] The molded rotating turntable bearing 432 with external teeth has a circle of meshing teeth on its outer ring and an inner ring fixed to the molded rotating base 431. A molded rotating gear 434 is also fixed to the molded rotating base 431. The molded rotating gear 434 meshes with the molded rotating turntable bearing 432.

[0275] The forming rotation mechanism 43 is connected to the forming translation mechanism 44, and the forming translation mechanism 44 is connected to the forming lifting mechanism 45, so that the forming lifting mechanism 45 drives the forming translation mechanism 44 to move up and down, and the forming translation mechanism 44 drives the forming rotation mechanism 43 to move in translation; or,

[0276] The molding rotating mechanism 43 is connected to the molding lifting mechanism 45 , and the molding lifting mechanism 45 is connected to the molding translation mechanism 44 , so that the molding translation mechanism 44 drives the molding lifting mechanism 45 to translate, and the molding lifting mechanism 45 drives the molding rotating mechanism 43 to move up and down.

[0277] like Figure 4-3 、 4-6 As shown in 4-7, the forming translation mechanism 44 can be either guide rail type translation or belt type translation as long as the scraper assembly can be translated or moved away from the mold. There are various structural forms on the market. The preferred structure of this patent includes a forming translation base 441 and a forming translation servo electric cylinder 443. A forming translation guide rail 444 is provided on the forming translation base 441, and a forming translation guide wheel 442 is slidably matched with the forming translation guide rail 444. The forming translation servo electric cylinder 443 is installed on the forming translation base 441.

[0278] The forming translation guide wheel 442 is installed on the forming rotation mechanism 43, the output end of the forming translation servo cylinder 443 is connected to the forming rotation mechanism 43 and provides the forming rotation mechanism 43 with power to move along the forming translation guide rail 444, the forming translation base 441 is fixed on the forming lifting mechanism 45, and the forming lifting mechanism 45 provides lifting power for the forming translation mechanism 44; or,

[0280] The shaped translation guide rail 444 is a dustproof V-shaped rail; the shaped translation guide wheel 442 is a dustproof V-shaped roller.

[0281] like Figure 4-4 、 4-5 As shown, the molding lifting mechanism 45 can make the scraper assembly leave the mold or enter the mold for processing. Therefore, the lifting mechanism has various forms such as rails, belts, and gears. There are many options on the market, but the preferred mechanism of this patent is more stable, which includes a molding lifting servo electric cylinder 451. The molding lifting servo electric cylinder 451 is fixed on the molding lifting frame 453. The output end of the molding lifting servo electric cylinder 451 provides lifting power for the molding lifting base 454. The molding lifting base 454 is equipped with a molding lifting guide shaft 452. The molding lifting frame 453 is equipped with a molding lifting guide wheel 457. The molding lifting guide wheel 457 is slidably connected to the molding lifting guide shaft 452.

[0282] The movable end of the molding lifting guide shaft 452 on the molding lifting base 454 is connected to the molding translation mechanism 44. The molding translation mechanism 44 includes a molding translation base 441. The molding rotation mechanism 43 is installed on the molding translation base 441. The molding translation mechanism 44 provides translational force for the molding rotation mechanism 43. The molding rotation mechanism 43 is connected to a scraper assembly. The molding translation base 441 is provided with a molding lifting positioning hole 4411. A molding lifting positioning pin 456 is also installed on the molding elevator. The molding lifting positioning pin 456 is plugged into and pulled out of the molding lifting positioning hole 4411 by the lifting and lowering of the molding translation mechanism 44.

[0283] Or, the movable end of the forming lifting guide shaft 452 on the forming lifting base 454 is connected to the forming rotating mechanism 43, and a scraper assembly is installed on the forming rotating mechanism 43. The forming rotating mechanism 43 includes a forming rotating base 431, and a forming lifting positioning hole 4411 is opened on the forming rotating base 431. A forming lifting positioning pin 456 is also installed on the forming elevator. The forming lifting positioning pin 456 is plugged in and out of the forming lifting positioning hole 4411 through the lifting and lowering of the forming rotating mechanism 43. A forming lifting mechanism 45 is installed on the forming translation mechanism 44 and provides translational force for the forming lifting mechanism 45.

[0284] The molding lift guide cage 455 is mounted on the upper portion of the molding lift frame 453. The molding lift guide wheel 457 is fixed in the molding lift guide cage 455. The molding lift base 454 is disposed at the lower portion of the molding lift frame 453. The molding lift servo electric cylinder 451 is mounted in the molding lift guide cage 455. The molding translation mechanism 44 or the molding rotation mechanism 43 is connected above the molding lift guide cage 455.

[0285] The molding lift positioning pins 456 are installed on both sides of the molding lift guide cage 455 .

[0286] The forming lifting frame 453 is also provided with a forming lifting chain for storing the wires used by the forming lifting mechanism 45 . One end of the forming lifting chain is connected to the fixed position of the forming lifting servo cylinder 451 , and the other end is connected to the forming lifting base 454 .

[0287] The aforementioned molding lifting mechanism 45 , molding rotating mechanism 43 , and molding translation mechanism 44 are all enclosed within the molding shell, and a molding operation interface 421 for viewing and operating the equipment operation status is installed outside the molding shell.

[0288] The figure shows that the scraper assembly is installed on the forming rotation mechanism 43, the forming rotation mechanism 43 is installed on the forming translation mechanism 44, and the forming lifting mechanism 45 drives the forming rotation mechanism 43 and the forming translation mechanism 44 to lift and lower together.

[0289] When the forming lifting servo electric cylinder 451 drives the forming lifting base 454 to rise, the forming translation base 441 connected to it through the forming lifting guide shaft 452 also moves upward, and the forming rotating base 431 slidingly connected to the forming translation base 441 can be displaced with the forming translation base 441 through the action of the forming translation servo electric cylinder 443, thereby driving the forming rotating mechanism 43 and the scraper assembly to translate, and the forming rotating mechanism 43 independently acts to rotate the scraper assembly.

[0290] Working principle:

[0291] The original position automatic control device is outside the mold. After the scraper assembly is lifted by the molding lifting mechanism 45, the molding translation mechanism 44 drives the scraper assembly to the top of the mold. The molding rotation mechanism 43 rotates the corresponding scraper assembly into place. The molding lifting mechanism 45 descends to the original position. When the sand starts to be thrown into the mold, the scraper assembly approaches the position where the sand needs to be scraped and accumulated. The rotation of the mold continuously acts on it, and finally the prototype of the quartz crucible is produced.

[0292] When processing the bottom of the mold, due to the "L"-shaped scraper body structure design in the scraper assembly, the quartz sand can be continuously moved toward the middle, thereby scraping the bottom smooth without any excess waste sand.

[0293] The molding lifting mechanism 45 and the molding rotating mechanism 43 are both provided with positioning structures, which can ensure that when the quartz crucible is processed, the entire molding control device is more stable and will not deviate, thereby ensuring the flatness of the sand scraping during the processing.

[0294] When the corresponding displacement is completed, the positioning structure starts to work, and the molding rotation positioning pin 433 is extended and inserted into the molding rotation positioning hole 437 to fix the molding rotation mechanism 43 and the scraper assembly;

[0295] The molding lift positioning pin 456 also extends out and is inserted into the molding lift positioning hole 4411 to fix the molding lift mechanism 45 and the molding scraper assembly 41 .

[0296] (1) The automatic forming control equipment of the quartz crucible can adapt to different mold forms, positions and quartz crucible processing requirements through the cooperation of the forming scraper assembly and the power mechanism that provides multiple dimensions of movement. It can meet the requirements of mechanical automatic scraping of the quartz sand in the mold and make it accumulate on the inner wall of the mold, and finally form the prototype of the quartz crucible, thereby achieving the purpose of automatic processing of the quartz crucible.

[0297] (2) The quartz crucible automatic forming control device is equipped with multiple forming scraper assemblies to meet the need to stack multiple layers of quartz sand of different qualities during the quartz crucible production process. Each time a layer of quartz sand (quartz sand of different qualities) is stacked, a forming scraper assembly is automatically replaced mechanically to prevent the current quartz sand from being contaminated by quartz sand of other qualities.

[0298] (3) The structural composition of the scraper assembly in the quartz crucible automatic forming control equipment can meet the requirements of the quartz crucible mold shape, and can scrape the inner wall and the bottom of the mold during the automatic scraping process, without causing unnecessary waste to accumulate at the bottom of the mold.

[0299] (4) The structure of the forming rotation mechanism in the automatic forming control equipment of the quartz crucible is selected to have a faster rotation speed, but a stable position after rotation, so as to meet the requirements of the scraper assembly during replacement and operation. The replacement needs to be fast and the position needs to be accurate. The scraper assembly that is currently working needs to be stable during operation, so as to further ensure the scraping quality and improve the qualified rate of the quartz crucible.

[0300] (5) The structure of the forming translation mechanism in the automatic forming control equipment of the quartz crucible is selected to be stable and prevent dust from falling into, which ensures the translational movement of the scraper assembly, makes the scraper assembly more free, and does not cause pollution to the quartz crucible.

[0301] (6) The structural design of the finished product lifting assembly in the automatic forming control equipment of the quartz crucible mainly achieves smooth lifting and after the scraper assembly is adjusted to a good position, the scraper assembly can maintain a stable position in the direction of lifting and lowering displacement, thereby improving the scraping stability of the scraper assembly during the processing of the quartz crucible and improving the production quality.

[0302] (7) In the quartz crucible automatic molding control equipment, the moving structure is wrapped in the molding shell to further ensure the cleanliness of the quartz crucible during the processing.

[0303] An embodiment of a separate structural design description of a quartz sand processing flying material collecting device 5:

[0304] like Figure 5-1 and 5-2 As shown, the quartz sand processing flying material collection device 5 includes a quartz sand collection silo 51;

[0305] The quartz sand collecting silo 51 includes a connected quartz sand collecting front end 513, a quartz sand collecting feeding part 511 and a quartz sand collecting discharging part 512; the quartz sand collecting silo 51 can be integrally formed or can be formed by splicing multiple shells, as long as the integrity of the collecting silo is ensured.

[0306] The bottom of the quartz sand collecting silo 51 can be designed to be inclined to ensure that the quartz sand collected from the collecting feed port flows out from the tail opening of the quartz sand collecting discharge part 512; or a reversible structure can be designed to allow the quartz sand in the quartz sand collecting silo 51 to flow out by reversing.

[0307] The opening of the quartz sand collecting front end portion 513 and the openings of the quartz sand collecting feed portion 511 and the quartz sand collecting discharge portion 512 form a collecting feed port. The external shape of the collecting feed port matches the external shape of the quartz crucible melting furnace mold 1 from which the pre-generated quartz sand splashes out; the quartz sand collecting discharge portion 512 is a trumpet-shaped shell to facilitate the outflow of the collected quartz sand.

[0308] The quartz sand collecting and discharging portion 512 has a tail opening, and the material entering the quartz sand collecting and discharging portion 512 is discharged through the tail opening.

[0309] The opening height of the quartz sand collecting and feeding part 511 is greater than the openings of the quartz sand collecting front end part 513 and the quartz sand collecting and discharging part 512, mainly because the quartz sand collecting and feeding part 511 located in the middle will receive more splashing quartz sand with a higher trajectory.

[0310] The quartz sand collecting silo 51 is installed at a preset position through the collecting silo support frame 552. The quartz sand collecting silo 51 rotates relative to the collecting silo support frame 552, with one extreme position being a vertical horizontal plane and the other extreme position being parallel to the horizontal plane.

[0311] It also includes a collecting silo turning shaft 573, and the quartz sand collecting silo 51 is connected to the collecting silo turning shaft 573. The collecting silo turning shaft 573 rotates with the collecting silo support frame 552 through the power provided by the collecting silo rotation servo motor 571.

[0312] Since the quartz sand collecting silo 51 can rotate, position detection and buffering are provided at the extreme positions to improve the practicality and lifespan of the quartz sand collecting silo 51 .

[0313] The collecting silo support frame 552 is equipped with a collecting silo horizontal in-place sensor 572 and a collecting silo horizontal buffer limiter 574. The collecting silo horizontal in-place sensor 572 detects the horizontal limit position of the collecting silo. The collecting silo horizontal buffer limiter 574 is installed at a horizontal limit movement position of the quartz sand collecting silo 51, and is used to provide elastic buffering force and position support to the quartz sand collecting silo 51.

[0314] The collecting silo support frame 552 is equipped with a collecting silo vertical position sensor 576 and a collecting silo vertical buffer limiter. The collecting silo vertical position sensor 576 detects the vertical limit position of the collecting silo. The collecting silo vertical buffer limiter is installed at a vertical limit movement position of the quartz sand collecting silo 51, and is used to provide elastic buffering force and position support to the quartz sand collecting silo 51.

[0315] The vertical buffer limiter and the horizontal buffer limiter of the collecting silo can be components with springs as the main body, or the components themselves can be paved with materials with elastic deformation, as long as they can support the collecting silo and play a limiting and buffering role for it.

[0316] like Figures 5-3 to 5-4 As shown, the position of the quartz sand collecting bin 51 relative to the quartz crucible melting furnace mold 1 can be adjusted in three directions: X, Y, and Z.

[0317] The position adjustment in the X-axis direction can be achieved as long as fine adjustment can be achieved. The design structure of this patent is:

[0318] The collection silo is connected to the collection silo support frame 552 via a collection connecting plate. This plate has a slotted hole 581 for adjusting the collection silo's X-direction position. The collection silo is bolted to this slotted hole 581, allowing adjustment of the collection silo's X-direction position based on the position of the slotted hole 581. The collection connecting plate is connected to a collection silo tilting shaft 573, which is rotatably connected to the collection silo support frame 552. When adjustments are needed, the collection silo can be fine-tuned in the X-direction by simply repositioning the bolts in the original slotted hole 581.

[0319] The position adjustment in the Y-axis direction can be achieved as long as fine adjustment can be achieved. The design structure of this patent is:

[0320] The collecting connecting plate is sleeved on the collecting bin turning shaft 573 through a key shaft, and the collecting bin is fixed in position relative to the collecting bin turning shaft 573 by inserting the key shaft into the collecting bin Y-direction adjustment key 582 .

[0321] The key shaft slides on the collection bin flip shaft 573. After sliding into place, the collection bin Y-direction adjustment key 582 is inserted into the key shaft for fixing, thereby achieving fine adjustment of the collection bin in the Y direction.

[0322] The position adjustment in the Z-axis direction can be achieved as long as fine adjustment can be achieved. The design structure of this patent is:

[0323] The bottom of the collecting silo support frame 552 is connected to a collecting silo Z-axis adjustment screw 583, and the other end of the collecting silo Z-axis adjustment screw 583 is screwed onto the collecting height adjustment bracket 551. Through the collecting silo Z-axis adjustment screw 583, the collecting silo support frame 552 can be displaced in the Z-axis direction relative to the collecting height adjustment bracket 551.

[0324] By rotating the Z-axis adjusting screw 583 of the collecting silo, the position of the collecting silo support frame 552 connected thereto can be adjusted, thereby satisfying the fine adjustment of the collecting silo in the Z-axis direction.

[0325] A receiving funnel 53 is provided below the tail opening of the quartz sand collecting and discharging portion 512 , and the receiving funnel 53 is fixed on a collecting bin support frame 552 ; the receiving funnel 53 is connected to a collecting barrel 56 below via a receiving hose 54 .

[0326] The material receiving hose 54 is fixedly installed on the collection height adjustment bracket 551. When the collection bin is displaced in the Z-axis direction, the material receiving hose 54 can remain unchanged due to its own characteristics and length, and can still maintain its relative position with the collection barrel 56 below, ensuring that the collected quartz sand still falls accurately into the collection barrel 56.

[0327] When the quartz crucible melting furnace mold 1 starts processing, splashing quartz sand will be generated. At this time, the quartz sand collecting silo 51 is placed near the mold, and the splashing quartz sand falls into the quartz sand collecting silo 51 .

[0328] The quartz sand collection silo design in the quartz sand processing flying material collection equipment can solve the problem of collecting quartz sand flying out of the quartz crucible melting furnace mold during the quartz crucible production process with a high degree of automation. The collected quartz sand can reduce the pollution of the surrounding environment, which is very necessary for both personnel and quartz sand materials; and the collected quartz sand can be used as low-quality materials, further saving costs.

[0329] The structural design features of the quartz sand collection silo are in line with the trajectory of quartz sand splashing out of the mold, ensuring that more quartz sand is collected and can flow more smoothly into the collection barrel.

[0330] The quartz sand collection silo can be rotated to a vertical position to ensure that all the quartz sand in the collection silo is poured out to avoid material contamination caused by residual material.

[0331] The quartz sand collection silo is adjustable in three directions to meet the requirements of molds of different specifications and quartz sand of different qualities, which increases the adaptability of the equipment and indirectly saves costs.

[0332] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
