Description

Technical Field

[0001] The invention belongs to the field of photovoltaics and semiconductors, and in particular relates to a fully automatic sand-loading molding system and a process method for a quartz crucible. Background Art

[0002] Quartz crucible is a subdivided product of quartz glass products. It is made of high-purity quartz sand through mold shaping and high-temperature production using the 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 the drawing of high-purity single crystal silicon rods for semiconductors. It is a key disposable consumable for containing 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 the output of quartz crucibles has also increased year by year, and at the same time, higher requirements are placed on the quality of quartz crucibles and their production processes.

[0003] The quartz crucible needs to be stacked with quartz sand of different qualities in each layer under high temperature. The quality of the added quartz sand also varies. 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 scrapped. 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 it involves improvements to traditional manual processing technology, are issues that need to be studied urgently. Summary of the invention

[0006] In view of this, the present invention aims to provide a fully automatic sand-feeding and molding system and process method for a quartz crucible to solve one of the above-mentioned problems.

[0007] To achieve the above object, the technical solution created by the present invention is implemented as follows:

[0008] A fully automatic sand forming process for a quartz crucible, the specific steps of which include:

[0009] The quartz crucible automatic feeding and shape and size control growth equipment are used to automatically throw the materials into the quartz crucible melting furnace mold;

[0010] The quartz crucible automatic forming control equipment cooperates with the quartz crucible melting furnace mold to scrape the material thrown into the quartz crucible melting furnace mold, so that it accumulates inside the quartz crucible melting furnace mold to form a quartz crucible prototype;

[0011] The quartz crucible is formed by the accumulation of at least two qualities of quartz sand. At least the first time the quartz crucible is automatically charged and the shape and size controlled growth equipment throws the material, it only throws the material to the inner wall of the quartz crucible melting furnace mold. After that, the quartz crucible is automatically charged and the shape and size controlled growth equipment performs material throwing work according to quartz sands of different qualities. At least the last time the quartz crucible is automatically charged and the shape and size controlled growth equipment throws the material, it throws the material to the inner wall of the quartz crucible melting furnace mold and makes the material accumulate on the inner wall. After that, the quartz crucible is automatically charged and the shape and size controlled growth equipment throws the material to the inner bottom of the quartz crucible melting furnace mold and makes the material accumulate on the inner bottom.

[0012] Furthermore, when the material has been accumulated on the inner bottom of the quartz crucible melting furnace mold, the quartz crucible automatic feeding and shape and size control growth equipment stops throwing the material on the inner bottom of the quartz crucible melting furnace mold, and then the quartz crucible automatic forming control equipment continues to scrape the inner bottom of the quartz crucible melting furnace mold for at least one circle.

[0013] Furthermore, the quartz crucible automatic feeding and shape and size control growth equipment is placed in the quartz crucible melting furnace mold, and the material is thrown from bottom to top;

[0014] The material throwing speed of the quartz crucible automatic feeding and shape and size control growth equipment to the inner wall of the quartz crucible melting furnace mold is greater than the material throwing speed of the inner bottom of the quartz crucible melting furnace mold.

[0015] Furthermore, the quartz crucible automatic feeding and shape and size control growth equipment is placed in the quartz crucible melting furnace mold, and the material throwing outlet is perpendicular to the inner wall of the quartz crucible melting furnace mold.

[0016] Furthermore, the scraper assembly of the quartz crucible automatic forming control device for scraping the material is replaced according to the different qualities of the scraped material;

[0017] Quartz crucible automatic feeding and shape and size control growth equipment is used to hold the feeding silo of the material to be thrown out, which can be replaced according to the different quality materials;

[0021] Furthermore, it also includes an automatic classification and transportation device for quartz crucible sand which automatically feeds the quartz crucible automatic feeding and shape and size control growth equipment. When the automatic classification and transportation device for quartz crucible sand feeds the quartz crucible automatic feeding and shape and size control growth equipment with materials of different qualities, different sand material barrels are used to weigh the materials and drop the materials into the quartz crucible automatic feeding and shape and size control growth equipment; the automatic classification and transportation device for quartz crucible sand can be lowered to the operating position to feed the sand material barrel at the operating position.

[0022] Furthermore, it also includes a quartz sand processing flying material collection device, which can automatically collect the waste thrown out of the quartz crucible melting furnace mold;

[0023] The automatic classification and handling equipment for quartz crucible sand classifies and loads materials of different qualities, and the automatic feeding and shape and size control growth equipment for quartz crucible feeds one quality of material each time. The automatic feeding and shape and size control growth equipment for quartz crucible weighs and determines the weight of the material and then throws the material into the quartz crucible melting furnace mold. The automatic forming control equipment for quartz crucible starts and scrapes the material thrown into the quartz crucible melting furnace mold, so that the material is accumulated in the quartz crucible melting furnace mold at the corresponding position;

[0024] In the process of scraping the same material, when the inner bottom of the quartz crucible melting furnace mold needs to be piled up, the inner wall of the quartz crucible melting furnace mold is scraped first, and then the inner bottom of the quartz crucible melting furnace mold is scraped;

[0025] After the quartz crucible automatic feeding and shape and size control growth equipment stops throwing materials, the quartz crucible automatic forming control equipment continues to act on the corresponding position of the quartz crucible melting furnace mold for one circle. At this time, the quartz crucible automatic feeding and shape and size control growth equipment moves out of the quartz crucible melting furnace mold, and then receives the quartz crucible sand automatic classification and handling equipment to load other materials;

[0026] During the movement of the quartz crucible automatic molding control device, the quartz sand processing flying material collection device collects the materials splashed out of the quartz crucible melting furnace mold;

[0027] In response to scraping materials of different qualities, the quartz crucible automatic forming control device replaces the scraper assembly for scraping the materials.

[0047] The outlet of the blowing pipe of the feeding valve leads to the inlet of the feeding supply pipe or the outlet of the feeding bin, and is used to blow gas into the corresponding pipeline.

For ordinary technicians in this field, the specific meanings of the above terms in the invention can be understood according to specific circumstances.

[0096] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0097] A fully automatic sand forming process for a quartz crucible, the specific steps of which include:

[0098] 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 device 3;

[0099] 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;

[0100] The quartz crucible is formed by the accumulation of at least two qualities of quartz sand. At least the first time the quartz crucible automatically feeds and the shape and size control growth device 3 throws the material, it only throws the material to the inner wall of the quartz crucible melting furnace mold 1. Then the quartz crucible automatically feeds and the shape and size control growth device 3 throws the material according to the different qualities of quartz sand. 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. Then, 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.

[0101] 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.

[0102] 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, so as to completely form the quartz crucible.

[0103] When the material has been 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 throwing the material on the inner bottom of the quartz crucible melting furnace mold 1, and then the quartz crucible automatic forming control device 4 continues to scrape the inner bottom of the quartz crucible melting furnace mold 1 for at least one circle. This ensures that no waste is generated and the materials are accumulated at the corresponding positions.

[0104] 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 stacked inside the quartz crucible melting furnace mold 1.

[0105] The material throwing speed of the quartz crucible automatic feeding and shape and size control growth device 3 to the inner wall of the quartz crucible melting furnace mold 1 is greater than the material throwing speed of the inner bottom of the quartz crucible melting furnace mold 1.

[0106] 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, and the problem of occupied space.

[0107] The scraper assembly for scraping the material in the automatic forming control device 4 of the quartz crucible is replaced according to the different quality materials being scraped. The feeding bin 3621 for accommodating the material to be thrown out in the automatic feeding and shape and size control growth device 3 of the quartz crucible is replaced according to the different quality materials; both are to avoid cross contamination and ensure the cleanliness of the material during the processing of the quartz crucible. When the scraper assembly works on the quartz crucible melting furnace mold 1, it is in a vertical horizontal plane state.

[0108] 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;

[0109] 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.

[0110] It also includes an automatic classification and handling device 2 for quartz crucible sand, which automatically feeds the automatic feeding and shape and size control growth device 3 for the quartz crucible. When the automatic classification and handling device 2 for quartz crucible sand feeds the automatic feeding and shape and size control growth device 3 with materials of different qualities, different sand material barrels 23 are used to weigh the materials and drop the materials into the automatic feeding and shape and size control growth device 3 for the quartz crucible; the automatic classification and handling 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.

[0111] It also includes a quartz sand processing flying material collection device 5, which can automatically collect the waste thrown out of the quartz crucible melting furnace mold 1.

[0112] If all of the above equipment are included, the specific process steps include:

[0114] In the process of scraping 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;

[0115] After the quartz crucible automatic feeding and shape and size control growth device 3 stops throwing materials, the quartz crucible automatic forming 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;

The classification barrel opening and closing valve 244 includes a baffle 2441 and a baffle 2441 movement mechanism.

[0144] 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 above-mentioned structure for operating displacement is also specifically described in the embodiments.

[0145] Semiconductor and solar quartz crucible sand automatic classification and handling equipment 2 separate structural design description of the embodiment:

[0146] like Figure 2-1 and 2-2 As shown, an automatic classification and transportation device 2 for semiconductor and solar quartz crucible sand includes a classification lifting mechanism 21, a classification rotating mechanism 22 and at least two sand barrels 23;

[0147] 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;

[0148] 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 .

[0149] The sand barrel 23 needs to be moved to the vicinity of the quartz crucible melting furnace mold 1 through the classification rotating mechanism 22 and the classification lifting mechanism 21 to facilitate blanking or loading. Generally, a weighing process will be required 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 equipment can also be used to directly add materials to the quartz crucible melting furnace mold 1, and selection can be made according to processing requirements.

[0150] 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 materials, and the classification rotating structure is used to determine which type of material to be dropped.

[0151] Due to the requirement of automatic classification and unloading, as long as the sand material barrel 23 carrying the material can be rotated and lifted and displaced, the requirement can be met. Therefore, the classification rotating 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 for lifting and is driven to rotate by the classification rotating mechanism 22. The other is that the classification lifting mechanism 21 drives the classification rotating mechanism 22 to lift and lower. The classification rotating mechanism 22 is connected to the sand material barrel 23, and the sand material barrel 23 can rotate according to the preset origin.

[0152] The specific installation structure is as follows:

[0153] 1. The classification rotating mechanism 22 is connected to the classification lifting mechanism 21, and the sand material barrel 23 is connected to the classification rotating mechanism 22 and the classification rotating mechanism 22 performs a rotational motion relative to the classification lifting mechanism 21;

[0154] 2. The classification lifting mechanism 21 is connected to the classification rotating mechanism 22, and the sand material tube 23 is connected to the classification lifting mechanism 21 and the classification rotating mechanism 22 makes the classification lifting mechanism 21 rotate around a preset origin, and the sand material tube 23 follows the classification lifting mechanism 21;

[0155] The classification lifting mechanism 21 enables the sand material barrel 23 to move up and down relative to a preset origin.

[0156] 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;

[0157] 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 on the classification rotation fixed seat 225, the output end of the classification rotation servo motor 221 is connected to the classification rotation driving teeth 224, and the classification rotation driving teeth 224 are meshed with the outer ring of the classification rotation external tooth bearing 223;

[0158] The sand material barrel 23 is connected to the outer ring of the classification rotating external gear bearing 223, and the classification rotating fixed seat 225 is connected to the classification lifting mechanism 21;

[0159] Furthermore, a classification rotation limiter 222 is provided on the outer ring of the classification rotation external gear bearing 223, which is used to limit the rotation position of the classification rotation external gear bearing 223, and can be realized by selecting a limit sensor or a mechanical blocking structure. When the preset position that the corresponding sand material barrel 23 should reach is set, the classification rotation limiter 222 can prevent the sand material barrel 23 from rotating excessively, and can also play a role in limiting its corresponding position; of course, the main function of the sand material barrel 23 reaching a fixed position is achieved by controlling the classification rotation servo motor 221.

[0160] The classification lifting mechanism 21 includes a classification lifting bracket 219, a classification lifting servo motor 214 and a classification lifting driving rack 213;

[0161] The classification lifting driving 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 meshed with the classification lifting rack, and the classification lifting servo motor 214 is fixed on the classification lifting seat;

[0162] 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.

[0163] When the classification lifting mechanism 21 rotates with the classification rotating mechanism 22, the specific connection method is as follows:

[0164] 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 material barrel 23 is connected to the classification lifting mechanism 21 in a lifting manner.

[0165] 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.

[0166] Regardless of the connection method adopted 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, and 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 lifting and lowering. At the same time, the V-shaped method can effectively reduce the pollution of impurities and dust to the falling materials, thereby ensuring that the machine can still be used and operated normally in a non-high cleanliness environment.

[0167] Furthermore, a classification lifting locking hole 218 is also provided in the classification lifting bracket 219, and a classification lifting limit locking cylinder 217 is also provided on the classification lifting seat. The output end of the classification lifting limit locking cylinder 217 is connected to a locking member, and the locking member 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 overall classification lifting mechanism 21. Therefore, more classification lifting locking holes 218 can be provided on the classification lifting bracket 219 to meet different travel requirements.

[0168] 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.

[0169] 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.

[0170] like Figure 2-3 , 2-4 2-9 is a schematic diagram of 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.

[0171] 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 choices of valve bodies. You can choose a valve body with only opening and closing functions (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 gate valves, stop valves, butterfly valves, ball valves, etc.

[0172] In order to better match the size and position of the material discharged by the sand barrel 23, this patent innovates a valve body structure, which is as follows:

[0173] The discharge point of the sand barrel 23 is connected to the outside through a 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 causes the baffle 2441 to be displaced relative to the pipe mouth of the classification barrel discharge pipe 246. One extreme position of the displacement of the baffle 2441 is to be 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.

[0174] Or, a graduation groove is provided in the middle of the classification barrel discharge pipe 246, and the graduation groove is adapted to the baffle 2441;

[0175] 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 make the nozzle of the discharge pipe 246 of the classification barrel communicate with the outside world. Another extreme position is to be completely inserted into the indexing groove and to isolate the discharge pipe 246 of the classification barrel from being connected with the outside world.

[0176] The baffle plate 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;

[0177] The classification barrel discharge mounting plate 247 is provided with a classification barrel blowing hole 245, and an air generator is connected to the classification barrel discharge pipe 246 through the classification barrel blowing hole 245, and the air blown by the air generator can act on the inside of the classification barrel discharge pipe 246. The air generator can also be directly connected to the classification barrel discharge through an air pipe. The air is blown into the classification barrel discharge pipe 246 or the outlet of the sand barrel 23 by the air generator. Whether it is the nozzle of the classification barrel discharge pipe 246 or the outlet of the sand barrel 23, it can be called the blanking outlet, that is, the part connected to the external environment. The classification barrel discharge pipe 246 or the outlet of the sand barrel 23 are both funnel-designed, which is convenient for discharge.

[0178] 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.

[0179] Furthermore, the sand-classifying component 24 also includes a classifying barrel vibrator 243 and a classifying barrel blowing component;

[0180] The classification barrel vibrator 243 is installed at the discharge point of the sand barrel 23 to generate vibration at the discharge point of the sand barrel 23;

[0181] The blowing component of the classification barrel comprises 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.

[0182] It also includes a classification valve group protective cover 241, which 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 blowing pipeline in the classification barrel blowing component, so as to prevent the moving parts from generating pollutants and falling into the quartz sand.

[0183] 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 higher 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.

[0184] Working principle: (Take the classification rotating mechanism 22 installed on the classification lifting mechanism 21 as an example)

[0185] A plurality of sand material barrels 23 are provided as required. Here, five sand material barrels 23 are taken as an example. The five sand material barrels 23 are installed together through a classification mounting plate. The classification mounting plate is installed on the classification rotating mechanism 22, specifically, on the outer shaft of the classification rotating external gear bearing 223;

[0186] 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;

[0187] First, the sand barrel 23 is lowered to a position that can be reached by a person or a machine through the classification lifting mechanism 21. After the person or machine adds quartz sand of corresponding quality into each sand barrel 23, the sand barrel 23 rises to a preset position, and the classification rotation servo motor 221 in the classification rotation mechanism 22 is started to rotate the sand barrel 23. Which sand barrel 23 needs to rotate to the corresponding position can be controlled by the classification rotation servo motor 221.

[0188] Then, the classification barrel opening and closing valve 244 is started to control the opening and closing of the valve body to cooperate with the blanking of the sand barrel 23. If the valve body of the invention 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;

[0189] During this period, the classification barrel vibrator 243 and the air generator are turned on so that there is always a sense of vibration and air blown out at the material drop position to prevent the material station from being attached to the outlet of the drop.

[0190] (1) The automatic sand sorting and handling equipment for semiconductor and solar quartz crucibles is equipped with multiple rotatable and liftable sand barrels to 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 quartz crucibles during processing, different sand barrels can reduce the contamination between materials of different qualities. The classification barrel opening and closing valve is used to control the amount of sand falling from the sand barrel, which also meets 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 lack of cleanliness and consistency.

[0191] (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.

[0192] (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, "hanging on the wall" may occur during the blanking process. 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. The quartz sand added to the sand barrel later will not be mixed with the previous quartz sand, thereby improving the cleanliness and ensuring the quality of subsequent quartz crucible processing.

[0193] (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.

[0194] (5) The structural design of the classification and rotation mechanism of the automatic classification and transportation equipment for semiconductor and solar quartz crucible sand can not only satisfy the requirement 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.

[0195] (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.

[0196] Quartz crucible automatic feeding and shape and size control growth equipment 3 separate structural design description embodiment:

[0197] like Figure 3-1 , 3-2 As shown, the quartz crucible automatic feeding and shape size control growth device 3 includes a feeding and control mechanism 36, a feeding rotation mechanism 33, a feeding translation mechanism 35 and a feeding lifting mechanism 34;

[0198] The feeding and control mechanism 36 includes a feeding bin 3621, a feeding valve assembly for controlling the degree of communication between the material in the feeding bin 3621 and the outside world, and a bin weighing assembly 364 for weighing the material in the feeding bin 3621. The material in the feeding bin 3621 falls into the throwing plate 3638 through the feeding valve assembly, and the throwing plate 3638 rotates to throw the material out;

[0199] The feeding rotating mechanism 33 is used to control the feeding and control mechanism 36 to rotate at a preset origin;

[0200] The feeding translation mechanism 35 is used to control the feeding and control mechanism 36 to approach or move away from the preset material throwing position;

[0201] The feeding lifting mechanism 34 is used to control the feeding and control mechanism 36 to rise or fall relative to the position where the material needs to be thrown away;

[0202] The feeding rotating mechanism 33, the feeding translating 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 material needs to be thrown away.

[0203] like Figure 3-5 As shown, the feeding and control mechanism 36 includes a plurality of feeding bins 3621, each of which corresponds to a different spinner 3638, each of which is connected via a feeding connecting frame 361, and a plurality of feeding connecting frames 361 converge at one point to be connected to the motion mechanism, and the power mechanism of the spinner 3638 rotating the synchronous belt pulley group 3635 is also installed on the feeding connecting frame 361.

[0204] The feeding bin 3621 is an open funnel-shaped bin body, the feeding bin 3621 is covered with a feeding bin cover 3621, and the feeding bin cover 3621 is opened with a feeding bin cover opening;

[0205] The cover of the feeding silo 3621 is provided with a silo cover sealing plate 3624, the edge of the cover of the feeding silo 3621 is provided with a protruding enclosure, the silo cover is closed and covers above the enclosure, the silo cover sealing plate 3624 can rotate relative to the cover of the feeding silo 3621, and the silo cover sealing plate 3624 is provided with a feeding silo 3621 blowing pipe on the surface opposite to the feeding silo 3621, and the feeding silo 3621 blowing pipe is connected to an air generator, and the air generator blows gas into the feeding silo 3621 through the feeding silo 3621 blowing pipe, which helps the material in the feeding silo 3621 to fall without hanging on the wall.

[0206] 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 bin 3621. One extreme position of the displacement of the feeding valve baffle 3652 is to be completely away from the outlet of the feeding bin 3621 and to make the outlet of the feeding bin 3621 connected to the outside world. The other extreme position is to completely cover the outlet of the feeding bin 3621 and isolate the feeding bin 3621 from the outside world.

[0241] Working principle:

[0242] The feeding translation mechanism 35 is installed on the operating electric cabinet 32, the feeding translation slider 332, 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, and the feeding connecting frame 361 is installed on the feeding lifting mounting seat 335 of the feeding lifting mechanism 34.

[0243] The operating 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.

[0244] When quartz sand needs to be added to the feeding bin 3621, first withdraw the feeding bin 3621 to an original position, lower the feeding bin 3621 to the bottom, add the material through the cover of the feeding bin 3621, and then rotate the bin cover sealing plate 3624 to cover it.

[0245] The weight of the added material is weighed by the silo weighing component 364 to check whether it meets the weight requirement.

[0246] The feeding bin 3621 is raised, and the feeding bin 3621 is 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 .

[0247] Start the air blowing pipe of the feeding bin 3621 to blow air into the inside of the feeding bin 3621 to ensure smooth material dropping;

[0248] The feeding valve baffle 3652 is started to open 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 rotating motor 3631 of the throwing plate 3638 is turned on to make the throwing plate 3638 rotate, and the material falls into the throwing plate 3638 and is thrown to the outside by centrifugal force.

[0249] (1) The feeding and control mechanism of the growth equipment for automatic feeding and shape and size control of quartz crucible can mechanically realize the falling of quartz sand materials according to the required weight, and through the setting of multiple motion mechanisms, three-dimensional angle operation is realized, 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 avoid the processing and forming position of the quartz crucible when feeding into the feeding bin, and further improve 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.

[0250] (2) Automatic feeding and shape and size control of quartz crucibles The design of multiple feeding bins 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.

[0251] (3) The cover plate of the silo of the quartz crucible automatic feeding and shape and size control 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 smoothness of the falling of the material in the feeding silo and prevent the material from sticking to the feeding silo.

[0252] (4) Automatic feeding and shape and size control of quartz crucibles. The feeding valve assembly of the growth equipment can control the feeding time of the feeding bin and the feeding speed. This can be achieved by controlling the outlet size of the feeding bin. 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.

[0253] (5) The structure of the spinner assembly of the quartz crucible automatic feeding and shape and size control growth equipment can ensure that when the spinner is rotating, pollutants generated by other moving parts will not fall into the spinner. At the same time, the spinner 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 subsequent processes.

[0254] (6) The combination of various 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, the feeding rotating mechanism, and the 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, thereby improving the cleanliness of the quartz sand discharged.

[0255] An embodiment of a separate structural design description of a quartz crucible automatic molding control device 4:

[0260] The scraper assembly also includes a molded scraper side scraper portion 413, which is installed on the side of the "L"-shaped scraper body. The working surface of the molded 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.

[0261] The side scraper portion 413 of the molded scraper can act on the inner wall of the mold, and the L-shaped scraper body can act on the inner bottom of the mold. Then, the scraper assembly can satisfy the action relationship on the entire mold, meeting the requirements of automatic processing of quartz crucibles.

[0262] The forming rotating mechanism 43 is used for the forming scraper assembly 41 to rotate at a preset origin;

[0263] The forming translation mechanism 44 is used for the forming scraper assembly 41 to approach or move away from a preset position for carrying the material to be scraped;

[0265] The forming rotating mechanism 43, the forming translating mechanism 44 and the forming lifting mechanism 45 cooperate with each other to make the forming scraper assembly 41 move relative to the preset position of the material to be scraped.

[0271] The molding rotation mechanism 43 is connected to the molding translation mechanism 44, and the molding translation mechanism 44 is connected to the molding lifting mechanism 45, so that the molding lifting mechanism 45 drives the molding translation mechanism 44 to rise and fall, and the molding translation mechanism 44 drives the molding rotation mechanism 43 to translate; or,

[0272] 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.

[0273] like Figure 4-3 , 4-6 As shown in 4-7, the molding translation mechanism 44 can be either guide rail type translation or belt type translation as long as the scraper assembly can be translated or away from the mold. There are various structural forms on the market. The preferred structure of this patent includes a molding translation base 441 and a molding translation servo electric cylinder 443. A molding translation guide rail 444 is provided on the molding translation base 441, and a molding translation guide wheel 442 is slidably matched with the molding translation guide rail 444. The molding translation servo electric cylinder 443 is installed on the molding translation base 441;

[0274] The forming translation guide wheel 442 is installed on the forming rotation mechanism 43, the output end of the forming translation servo electric 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,

[0276] The molded translation guide rail 444 is a dustproof V-shaped rail; the molded translation guide wheel 442 is a dustproof V-shaped roller.

[0277] 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, so 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, and 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, and the molding lifting frame 453 is equipped with a molding lifting guide wheel 457. The molding lifting guide wheel 457 is slidably connected with the molding lifting guide shaft 452;

[0278] The movable end of the molding lifting guide shaft 452 on the molding lifting base 454 is connected to the molding translation mechanism 44, and 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 with 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 and pulled out of the molding lifting positioning hole 4411 through the lifting and lowering of the molding translation mechanism 44.

[0279] 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.

[0280] It also includes a molding lifting guide cage 455 installed on the upper part of the molding lifting frame 453, the molding lifting guide wheel 457 is fixed in the molding lifting guide cage 455, the molding lifting base 454 is set at the lower part of the molding lifting frame 453, the molding lifting servo electric cylinder 451 is installed in the molding lifting guide cage 455, and the molding translation mechanism 44 or the molding rotation mechanism 43 is connected above the molding lifting guide cage 455;

[0281] The molding lifting positioning pins 456 are installed on both sides of the molding lifting guide cage 455 .

[0282] A forming lifting chain for storing the wires used by the forming lifting mechanism 45 is also provided in the forming lifting frame 453 . One end of the forming lifting chain is connected to a fixed position of the forming lifting servo electric cylinder 451 , and the other end is connected to the forming lifting base 454 .

[0283] The aforementioned molding lifting mechanism 45 , molding rotating mechanism 43 , and molding translation mechanism 44 are all enclosed inside a molding shell, and a molding operation interface 421 for viewing and operating the operation status of the equipment is installed outside the molding shell.

[0284] Here, the scraper assembly is shown to be installed on the molding rotating mechanism 43, and the molding rotating mechanism 43 is installed on the molding translation mechanism 44. The molding lifting mechanism 45 drives the molding rotating mechanism 43 and the molding translation mechanism 44 to lift and lower together.

[0285] When the molding lifting servo electric cylinder 451 drives the molding lifting base 454 to rise, the molding translation base 441 connected to it through the molding lifting guide shaft 452 also moves upward, and the molding rotating base 431 slidingly connected to the molding translation base 441 can be displaced with the molding translation base 441 through the action of the molding translation servo electric cylinder 443, thereby driving the molding rotating mechanism 43 and the scraper assembly to translate, and the molding rotating mechanism 43 independently acts to rotate the scraper assembly.

[0286] Working principle:

[0287] 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 to the right position. The molding lifting mechanism 45 descends to the original position. When the sand starts to be thrown into the mold, the scraper assembly is close to the position where the sand needs to be scraped and accumulated. The mold rotates and acts continuously, and finally the prototype of the quartz crucible is produced.

[0288] 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 to the middle, so that the bottom can be scraped and smoothed without any excess waste sand.

[0289] 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 scraping during the processing.

[0290] 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;

[0291] The molding lifting positioning pin 456 also extends out and is inserted into the molding lifting positioning hole 4411 to fix the molding lifting mechanism 45 and the molding scraper assembly 41 .

[0292] (1) The automatic forming control equipment of the quartz crucible automatic forming control equipment 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 multi-dimensional 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.

[0293] (2) Multiple forming scraper assemblies are arranged in the quartz crucible automatic forming control device to meet the need to stack multiple layers of quartz sand of different qualities during the quartz crucible manufacturing 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.

[0294] (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.

[0295] (4) The structure of the forming rotation mechanism in the automatic forming control equipment of the quartz crucible adopts a structural design with a faster rotation speed but a stable position after rotation 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. When working, the scraper assembly needs to be in a stable position, so as to further ensure the scraping quality and improve the qualified rate of the quartz crucible.

[0296] (5) The structure of the forming translation mechanism in the automatic forming control equipment of the quartz crucible is stable and dust-proof, which ensures the translational movement of the scraper assembly, making the scraper assembly more free and not causing pollution to the quartz crucible.

[0297] (6) The structural design of the finished product lifting assembly in the automatic forming control equipment for quartz crucibles mainly achieves smooth lifting and lowering. 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 quartz crucibles and improving production quality.

[0298] (7) In the automatic forming control equipment for quartz crucibles, the moving structure is wrapped in a forming shell in order to further ensure the cleanliness of the quartz crucible during the processing.

[0299] Quartz sand processing flying material collecting device 5 separate structural design description embodiment:

[0300] 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;

[0301] 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.

[0302] 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 inlet 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.

[0303] 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, and 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.

[0304] 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.

[0305] 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.

[0306] The quartz sand collecting silo 51 is installed at a preset position through the collecting silo support frame 552, and the quartz sand collecting silo 51 rotates relative to the collecting silo support frame 552, wherein one extreme position is a vertical horizontal plane, and the other extreme position is a parallel horizontal plane.

[0307] It also includes a collecting silo turning shaft 573, the quartz sand collecting silo 51 is connected to the collecting silo turning shaft 573, and 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.

[0308] Since the quartz sand collecting silo 51 can rotate, position detection and buffering at the extreme position are provided to increase the practicality and life of the quartz sand collecting silo 51 .

[0309] 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 extreme position of the collecting silo. The collecting silo horizontal buffer limiter 574 is installed at a horizontal extreme 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.

[0310] 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.

[0311] 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.

[0312] like Figure 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.

[0313] The position adjustment in the X-axis direction can be achieved as long as micro-adjustment can be achieved. The design structure of this patent is:

[0314] The collecting silo is connected to the collecting silo support frame 552 through a collecting connecting plate, and a collecting silo X-direction adjustment slot 581 is provided on the collecting connecting plate. The collecting silo is fixedly connected to the collecting silo X-direction adjustment slot 581 through a bolt, and the displacement of the collecting silo in the X direction is adjusted according to the position of the collecting silo X-direction adjustment slot 581. The collecting connecting plate is connected to the collecting silo flip shaft 573, and the collecting silo flip shaft 573 is rotatably connected to the collecting silo support frame 552. When adjustment is required, the collecting silo can be fine-tuned in the X direction by simply fixing the bolts to the original position of the collecting silo X-direction adjustment slot 581.

[0315] 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:

[0316] The collecting connecting plate is sleeved on the collecting bin flipping shaft 573 via a key shaft, and the collecting bin is fixed in position relative to the collecting bin flipping shaft 573 by inserting the key shaft into the Y-direction adjustment key 582 of the collecting bin.

[0317] 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.

[0318] The position adjustment in the Z-axis direction can be achieved as long as micro-adjustment can be achieved. The design structure of this patent is:

[0319] A collecting silo Z-axis adjusting screw 583 is connected to the bottom of the collecting silo support frame 552, and the other end of the collecting silo Z-axis adjusting screw 583 is screwed onto the collecting height adjusting bracket 551. The collecting silo Z-axis adjusting screw 583 allows the collecting silo support frame 552 to be displaced in the Z-axis direction relative to the collecting height adjusting bracket 551.

[0320] By rotating the Z-axis adjusting screw 583 of the collecting silo to move up and down, the position of the collecting silo support frame 552 connected thereto can be adjusted to meet the needs of fine-tuning the collecting silo in the Z-axis direction.

[0321] A receiving funnel 53 is provided below the tail opening of the quartz sand collecting and discharging portion 512 . 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 through a receiving hose 54 .

[0322] The material receiving hose 54 is fixedly mounted on the collection height adjustment bracket 551. When the collection bin is displaced in the Z-axis direction, the material receiving hose 54 may not be displaced due to its own characteristics and length, and can still maintain its relative position with the collection barrel 56 below, thereby ensuring that the collected quartz sand still accurately falls into the collection barrel 56.

[0323] When the quartz crucible melting furnace mold 1 starts processing, splashing quartz sand will be generated. At this time, the quartz sand collecting bin 51 is placed near the mold, and the splashing quartz sand falls into the quartz sand collecting bin 51.

[0324] The quartz sand collection silo design in the quartz sand processing flying material collection equipment can solve the problem of collecting quartz sand splashed from 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 necessary for both personnel and quartz sand materials; and the collected quartz sand can continue to be used as poor quality materials, further saving costs.

[0325] 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.

[0326] The quartz sand collection silo can be rotated to a vertical state to ensure that all the quartz sand in the collection silo is poured out to avoid material contamination caused by residues.

[0327] 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.

[0328] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
