Technical Field
[0001] This invention relates to the field of crystallization furnace technology, specifically to a multi-stage, stable feeding, continuous growth horizontal Bridgeman furnace. Background Technology
[0002] The Bridgman crystal growth method, also known as the crucible lowering method, is a commonly used crystal growth method. It is divided into the vertical Bridgman method and the horizontal Bridgman method. Bridgman furnaces are widely used in the crystal growth industry, often involving air sintering. The horizontal Bridgman method is used to prepare large-area, shaped, thin-plate crystals. The raw material is placed in a boat-shaped crucible, which is then horizontally passed through the heating zone, melting and crystallizing the raw material. To grow crystals with strict orientation, a seed crystal can be placed in a seed slot at the top of the crucible to induce growth.
[0003] Current Bridgman furnaces, when melting seed crystals in crucibles, suffer from slow melting processes, making continuous feeding of seed crystals inconvenient and affecting the efficiency of seed crystal transport and processing.

[0016] Compared with the prior art, the beneficial effects of the present invention are:
[0017] 1. In this invention, two drive rollers are used to horizontally transport the crucible between the rear ends of two guide bars via two conveyor belts. This allows the second hydraulic cylinder to drive three actuating seats through the waist-shaped hole via the guide slide and drive screw, and insert them into the inner side of the furnace body, cooling box, and preheating box respectively. The drive motor drives the three actuating seats to slide forward on the inner side of the guide slide via the drive screw. This allows the actuating seats to move the crucible between the two guide bars, facilitating its movement to the inner side of the preheating box. The conical diverter seat injects air into the cooling box through multiple cooling air conveying sleeves. After being heated in the furnace body by two heating plates, the air is transported to the preheating box through the airflow in the cooling box, thus facilitating the preheating of the seed crystal in the crucible.
[0018] 2. This invention utilizes airflow within the cooling chamber to cool the molten seed crystals, accelerating the formation of plate-like crystals. A synchronous conveying mechanism enables multi-stage conveying of the crucibles, facilitating continuous preheating, melting, and cooling of seed crystals in multiple crucibles. Multiple sensors on the upper surface of the conveyor support plate monitor the crucible loading position, ensuring precise connection between the actuating seat and the crucible. Multiple cooling air conveying sleeves ensure uniform cooling of the plate-like crystals during the introduction of cold air. The preheating chamber is connected to the reflux sleeve and exhaust sleeve via connecting sleeves. Adjusting the airflow within the reflux and exhaust sleeves allows for control of the amount of airflow exiting the preheating chamber through the exhaust sleeve, thereby adjusting the furnace temperature and achieving preheating and cooling operations while preventing excessive temperature fluctuations within the furnace.

[0034] The furnace body 101 is fixedly connected to the cooling box 301 and the preheating box 401 by two guide strips 103.

The actuating seats 606 are used to switch the two positioning holes, thereby facilitating the movement of the crucible 7.
[0035] Please see Figures 1 to 4 The feeding and conveying mechanism 2 includes a conveying frame 201. Two conveyor belts 202 are installed on the inner side of the conveying frame 201. Two drive rollers 203 are installed on the inner side of both ends of the two conveyor belts 202. A conveying support plate 204 is fixedly installed in the middle of the conveying frame 201. Multiple sensing sensors 205 are fixedly installed on the upper surface of the conveying support plate 204.

The multiple sensing sensors 205 can monitor the feeding position of the crucible 7, thereby realizing the precise insertion of the actuating seat 606 and the crucible 7.
[0036] Please see Figure 4 , Figure 6 and Figure 7Both the cooling mechanism 3 and the preheating mechanism 4 have an active sealing mechanism 5 installed at their far ends. The active sealing mechanism 5 includes a first hydraulic cylinder 501. A sealing plate 502 is fixedly installed at the output end of the first hydraulic cylinder 501. Guide angle plates 503 are slidably connected to both ends of the sealing plate 502. The cooling box 301 and the preheating box 401 are fixedly connected to the guide angle plates 503. The bottom ends of the two sealing plates 502 are respectively inserted between the cooling box 301 and the preheating box 401 and the guide angle plates 503. The two first hydraulic cylinders 501 are fixedly connected to the cooling box 301 and the preheating box 401. The sealing plates 502 are inserted between the two guide angle plates 503 by the first hydraulic cylinders 501, so that the two sealing plates 502 can respectively seal the far ends of the cooling box 301 and the preheating box 401, thereby avoiding interference from the external environment to the seed crystal processing.
[0037] In summary, when generating crystals, the crucible 7 containing the seed crystal is placed on the upper surface of the two conveyor belts 202. The power is turned on, and the two drive rollers 203 horizontally transport the crucible 7 to the rear end of the two guide bars 103 via the two conveyor belts 202. When the crucible 7 moves to the inside of the preheating box 401, the second hydraulic cylinder 604 is activated. Under the support of the mounting base 603, the second hydraulic cylinder 604 drives the three actuating seats 606 through the waist-shaped hole and into the inside of the furnace body 101, the cooling box 301 and the preheating box 401 respectively via the guide slide 601 and the drive screw 605. One of the actuating seats 606 located at the rear can be inserted into the positioning hole located at the front.
[0038] Then, the drive motor 602 is started, which, under the support of the guide slide 601, drives the three actuating seats 606 to slide forward on the inner side of the guide slide 601 through the drive screw 605. The actuating seats 606 can then move the crucible 7 between the two guide bars 103, making it easier to move the crucible 7 to the inner side of the preheating box 401. At this time, the conical flow divider 302 injects gas into the cooling box 301 through multiple cooling air conveying sleeves 304. After being heated in the furnace body 101 by the two heating plates 105, the gas is transported to the preheating box 401 through the airflow in the cooling box 301, thus facilitating the preheating of the seed crystal in the crucible 7.
[0039] After preheating, the toggle seat 606 is adjusted so that it can switch the two positioning holes. The crucible 7 is then moved by the toggle seat 606 to move it into the furnace body 101. The seed crystal in the crucible 7 is then heated and melted by the two heating plates 105. After melting, the crucible 7 is moved by the toggle seat 606 to move it into the cooling box 301. The airflow in the cooling box 301 cools the melted seed crystal and accelerates the formation of plate crystals. The crucible 7 is then output through the feeding inclined plate 104. The crucible 7 can be transported in multiple stages by the synchronous conveying mechanism 6, which facilitates the continuous preheating, melting and cooling of the seed crystals in multiple crucibles 7. At the same time, the feeding position of the crucible 7 can be monitored by multiple sensors 205 on the upper surface of the conveying support plate 204, thereby achieving precise insertion between the toggle seat 606 and the crucible 7.
[0040] During seed crystal processing, preheating, melting, and cooling, two active sealing mechanisms 5 seal the cooling box 301 and the preheating box 401. Specifically, the first hydraulic cylinder 501 drives the sealing plate 502 to be inserted between the two guide angle plates 503, so that the two sealing plates 502 can seal the ends of the cooling box 301 and the preheating box 401 respectively, thereby avoiding interference from the external environment to the seed crystal processing. At the same time, the width of the multiple cooling air conveying sleeves 304 decreases from back to front. The multiple cooling air conveying sleeves 304 can facilitate the uniform cooling of the flaky crystals during the introduction of cold air, and the filter cotton in the filter box 303 can keep the airflow clean.
[0041] The preheating box 401 is connected to the reflux sleeve 403 and the exhaust sleeve 404 through the connecting sleeve 402. By adjusting the airflow in the reflux sleeve 403 and the exhaust sleeve 404, it is easy to control the amount of airflow discharged from the preheating box 401 through the exhaust sleeve 404, thereby adjusting the temperature inside the furnace body 101. This allows for both preheating and cooling operations while preventing excessive temperature changes inside the furnace body 101.
[0042] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention.
