Abstract
Description
Technical Field
[0001] This utility model relates to the field of crystallization furnace technology, and in particular to an electric heating microcrystalline glass pot continuous annealing crystallization furnace. Background Technology
[0002] A crystallization furnace is a high-temperature device used for material synthesis or crystal growth. Its core function is to precisely control temperature and atmosphere to achieve the crystallization process. It is widely used in the production of ceramics, metal alloys, semiconductor materials, and microcrystalline glass, using high-temperature treatment to form a stable crystalline structure within the material. An electrically heated microcrystalline glass pot continuous annealing crystallization furnace is a specialized industrial device for the production of microcrystalline glass pots. It uses resistance radiation heating to continuously anneal and crystallize microcrystalline glass. Its core function is to achieve the desired physical properties and crystallization effect of the microcrystalline glass pot through processes such as heating, heat preservation, and cooling.
[0003] To address this issue, patent CN208454810U discloses a modular microcrystalline glass annealing and crystallization furnace. The furnace includes a furnace body with a heating zone. A temperature equalization component is installed within the heating zone to separate the conveying component from the heating component. By placing temperature equalization components above and below the conveying component, a first, arc-shaped temperature equalization component creates a muffle effect above the conveying component, causing the heating surface to align with the glass workpiece surface, thus improving temperature uniformity. A second, M-shaped temperature equalization component forms a complete heating plane below the conveying component, further improving temperature uniformity and facilitating the removal of glass residue. This solves the technical problem of achieving temperature uniformity within a modular microcrystalline glass annealing and crystallization furnace, ensuring uniform temperature across all parts of the furnace, improving the crystallization quality of the microcrystalline glass, and simultaneously forming a complete heating plane below the conveying component, enhancing temperature uniformity and facilitating the removal of glass residue.
[0004] In the modular microcrystalline glass annealing and crystallization furnace mentioned above, the hot air inside the furnace body cannot circulate effectively during use, which makes it impossible to effectively recycle the hot air. The heated hot air is directly discharged outside the furnace, resulting in a large amount of heat waste, increased energy consumption, and uneven temperature throughout the furnace body, which can easily affect production quality.

[0010] The above structure allows for the installation and removal of the first and second heating rods during use, facilitating operation. Furthermore, the detachable design of both the first and second guide plates facilitates regular cleaning of the mesh on both plates, preventing clogging.
[0011] Preferably, the first heating rods are evenly spaced at the top of the box, and the second heating rods are evenly spaced at the bottom of the box.
[0012] With the above structure, the glass pot can be heated quickly through dual heating, resulting in uniform heat distribution and facilitating crystallization.
[0013] Preferably, both the first and second guide plates are made of RA330 alloy material, and the interiors of the first and second guide plates are uniformly provided with openings.
[0014] With the above structure, hot air can be forced to circulate through the first and second guide plates during use, improving heat exchange efficiency and thus enhancing temperature uniformity.
[0015] Preferably, the bottom end of the air inlet extends through the top of the housing and into the interior of the housing, and one end of the air duct extends through one side of the fan and into the interior of the fan.
[0016] With the above structure, the hot air inside the chamber is circulated through the ventilation duct during use, which further ensures the temperature uniformity of the chamber and makes the glass pot heat evenly, thereby improving production quality.
[0017] Preferably, the transport structure includes supports disposed on both sides of the box body, with rotating shafts installed on both sides inside the supports, a reduction motor fixed to one side of one end of the support of the rotating shaft, transmission rollers fixed to the outer side of the rotating shaft, and a conveyor belt installed on the outer side of the transmission rollers. Both sides of the box body are provided with openings, and a heat shield curtain is fixed to the top of the opening. Guide plates are fixed to both sides inside the box body.
[0018] Preferably, the conveyor belt is made of 310S stainless steel woven mesh, the openings are symmetrically distributed on both sides of the box, the heat shielding curtain is made of ceramic fiber material, and the guide plates are symmetrically distributed on both sides of the openings inside the box.
[0019] With the above structure, the heat shield curtain can effectively reduce temperature cross-contamination during use, and the guide plate can prevent the glass pot from sliding or shifting during transportation, thereby ensuring the processing quality of the glass pot.
[0020] The advantages of the electrically heated microcrystalline glass pot continuous annealing and crystallization furnace provided by this utility model are as follows:
[0021] By setting up a transport structure, the glass pot is placed at the top of the conveyor belt, and then the glass pot is transported from the opening into the interior of the box by the rotation of the conveyor belt. By setting up a heat shield curtain, the temperature cross-contamination can be effectively reduced, and by setting up a guide plate, the glass pot can be prevented from sliding or shifting during transport. After crystallization is completed, the glass pot is transported to the outside of the box by the conveyor belt, and then enters the annealing furnace for annealing treatment, thereby completing the processing of the glass pot.
[0022] By incorporating a heating structure, with the first and second heating rods installed at the upper and lower ends of the chamber at equal intervals, the glass pot can be rapidly heated through dual heating for crystallization, resulting in uniform heat distribution. The first and second guide plates force hot air to circulate, improving heat exchange efficiency and temperature uniformity. Simultaneously, a fan blows hot air from inside the chamber into the ventilation duct and then back into the chamber, achieving hot air circulation and further ensuring temperature uniformity throughout the chamber. This results in even heating of the glass pot and improved production quality. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Please see Figure 1-5 The electric heating microcrystalline glass pot continuous annealing crystallization furnace provided by this utility model includes a box body 1 and a heating structure 4.
[0031] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, support legs 2 are fixed at the bottom edge of the box 1. A transport structure 3 is installed inside the box 1. The transport structure 3 includes brackets 301 on both sides of the box 1. A rotating shaft 302 is installed on both sides inside the brackets 301. A geared motor 303 is fixed on one side of the brackets 301 at one end of the rotating shaft 302. A transmission roller 304 is fixed on the outside of the rotating shaft 302. A conveyor belt 305 is installed on the outside of the transmission roller 304. A passage 306 is provided on both sides of the box 1. A heat shield curtain 307 is fixed at the top of the passage 306. Guide plates 308 are fixed on both sides inside the box 1. The conveyor belt 305 is made of 310S stainless steel woven mesh. The passages 306 are symmetrically distributed on both sides of the box 1. The heat shield curtain 307 is made of ceramic fiber material. The guide plates 308 are symmetrically distributed on both sides of the passages 306 inside the box 1.
[0032] By placing the glass pot at the top of the conveyor belt 305 (310S stainless steel woven mesh), and then starting the geared motor 303 to drive the rotating shaft 302 to rotate the transmission roller 304, the glass pot is conveyed from the opening 306 into the interior of the housing 1 by the conveyor belt 305. A heat shield curtain 307, made of ceramic fiber material, is installed to effectively reduce temperature fluctuations. When the glass pot enters the interior of the housing 1, the geared motor 303 stops. A guide plate 308 is installed to prevent the glass pot from sliding or shifting during transport, allowing the glass pot to crystallize inside the housing 1 and ensuring the production quality of the glass pot. After crystallization, the geared motor 303 is started again to drive the conveyor belt 305 to transport the glass pot to the outside of the housing 1, where it enters the annealing furnace for annealing treatment, thus completing the processing of the glass pot.
[0033] Reference Figures 1-4As shown, heating structures 4 are installed on both sides of the interior of the housing 1. Each heating structure 4 includes a first heating rod 401 installed at the top of the interior of the housing 1, a second heating rod 402 installed at the bottom of the interior of the housing 1, a first guide plate 406 installed at the bottom of the first heating rod 401, a second guide plate 410 installed at the top of the second heating rod 402, a fan 412 installed at the top of the housing 1, an air inlet 413 at the bottom of the fan 412, a first heat insulation mesh 414 installed inside the air inlet 413, a second heat insulation mesh 415 installed at the bottom of the interior of the housing 1, and a ventilation duct 416 fixed at the bottom of the housing 1. Fixing blocks 403 are fixed to both ends of the first heating rod 401 and the second heating rod 402. A fixing groove 404 is provided inside the housing 1 outside the fixing block 403. An mounting plate 405 is fixed to one end of the fixing block 403 outside the housing 1. Support plates 407 are fixed to both sides of the bottom of the first guide plate 406 inside the housing 1. Connecting plates 408 are fixed to the other two sides of the top of the first guide plate 406 inside the housing 1. Ceramic bolts 409 are installed inside the connecting plates 408 and the first guide plate 406. Fixing plates 411 are fixed to the edge of the bottom of the second guide plate 410 inside the housing 1. The first heating rods 401 are evenly distributed at the top of the housing 1. The second heating rods 402 are evenly distributed at the bottom of the housing 1. The first guide plate 406 and the second guide plate 410 are both made of RA330 alloy. Openings are evenly arranged inside the first guide plate 406 and the second guide plate 410. The bottom of the air inlet 413 extends through the top of the housing 1 to the inside of the housing 1. One end of the air duct 416 extends through one side of the fan 412 to the inside of the fan 412. A door 5 is installed on one side of the housing 1.
[0034] The first heating rod 401 and the second heating rod 402 are fixed by inserting the fixing block 403 into the fixing groove 404, and then the mounting plate 405 is fixed by bolts. This allows for easy installation and removal of the first heating rod 401 and the second heating rod 402, facilitating use. Furthermore, the first heating rod 401 and the second heating rod 402 are evenly distributed at both ends inside the housing 1, enabling rapid heating of the glass pot for crystallization, resulting in uniform heat distribution. By activating the fan 412, the hot air inside the housing 1 is directed by the first guide plate 406 and the second guide plate 410. Forced circulation improves heat exchange efficiency and temperature uniformity. Both the first guide plate 406 and the second guide plate 410 are detachable, facilitating regular cleaning of the mesh on both plates to prevent clogging. Simultaneously, the fan 412 blows hot air from inside the housing 1 into the ventilation duct 416, then exhausts it through the duct into the fan 412 and outwards into the housing 1, achieving hot air circulation within the housing 1. This further ensures temperature uniformity throughout the housing 1, resulting in even heating of the glass pot and improved production quality.
