Description

Technical Field

[0001] This utility model relates to the field of high-temperature experimental furnace technology, specifically a fully automatic high-throughput multi-station high-temperature experimental furnace. Background Technology

[0002] A high-temperature experimental furnace is a device used for material experiments and research in a high-temperature environment. It is widely used in materials science, metallurgy, ceramics, electronics and other fields, and plays a key role in material research and development, performance testing and process optimization. It mainly consists of a furnace body, heating system, temperature control system, atmosphere control system and sample carrying device.

[0003] In the fields of materials research and development and experimentation, with the ever-increasing demands for experimental efficiency and data accuracy, the performance of high-temperature experimental furnaces faces even greater challenges. However, existing high-temperature experimental furnaces have significant shortcomings in multi-station capabilities, making it difficult to meet the growing needs of scientific research and production.

[0004] Currently, most high-temperature experimental furnaces only have single-station operation capabilities, meaning they can only test one sample at a time. This implies that when conducting multiple comparative experiments or large-scale material screening, each sample must be tested sequentially, consuming a significant amount of time. For example, when researching the sintering process of new ceramic materials, if it is necessary to test the performance of different formulations at different temperatures, a single-station experimental furnace can only process one sample at a time. Completing a comprehensive set of experiments can take several days or even weeks, severely slowing down the research progress. Utility Model Content

[0005] The purpose of this invention is to provide a fully automatic high-throughput multi-station high-temperature experimental furnace to solve the problems mentioned in the background art.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] A fully automatic high-throughput multi-station high-temperature experimental furnace includes a furnace body. The furnace body has several furnace chambers, each with an opening. A furnace door is located near each opening on the outer side of the furnace body, and the furnace door seals the opening. Furnace wires and temperature sensors are installed inside each furnace chamber. A tray is suspended within each furnace chamber. A pusher component is also located inside the furnace body, driving the tray to move horizontally. The free end of the tray is connected to the furnace door. A gas groove is also formed inside the furnace body. A solenoid valve connects the furnace chambers and the gas groove. The furnace chamber is equipped with a high-temperature pressure sensor. The design of multiple furnace chambers enables multi-station operation, allowing simultaneous experiments on multiple samples and greatly improving experimental efficiency. The furnace door, in conjunction with the pusher, allows for easy opening and closing of the furnace chamber, facilitating sample placement and removal. A temperature sensor monitors the temperature inside the furnace chamber in real time, ensuring the accuracy of experimental temperatures. A tray is used to carry samples, and its horizontally movable design facilitates sample entry and exit from the furnace chamber. The gas chamber, solenoid valve, and high-temperature pressure sensor work together to precisely control the atmosphere and pressure inside the furnace chamber, meeting the environmental requirements of different experiments. Furthermore, the pusher includes an electrically operated telescopic rod installed on the back of the furnace body. The furnace body has a sliding hole that communicates with the furnace chamber, and a sliding rod slides inside. The telescopic end of the electrically operated telescopic rod is connected to the sliding rod, and the tray is connected to the free end of the sliding rod. When the electrically operated telescopic rod is energized, its telescopic end extends or retracts according to control commands. When shortening, the slide bar slides within the sliding hole, causing the slide bar to move the tray into the furnace chamber, sending the sample into the furnace chamber; when extending, the slide bar and the tray move in opposite directions, thereby opening the furnace door, allowing the user to remove the sample at the same time.

[0008] Furthermore, a conical block is installed on the side of the furnace door near the furnace body. The shape of the opening matches the conical block. The radius of the conical block on the side near the furnace body is larger than the radius on the side away from the furnace body. The cooperation between the conical block and the opening enhances the sealing performance of the furnace door when it is closed, reduces heat loss and gas leakage, ensures the stability of the experimental environment inside the furnace, and improves the accuracy of the experimental results.

[0009] Furthermore, a first sealing ring is installed on the outer side of the slide rod, and a second sealing ring is installed on the outer side of the conical block. The first and second sealing rings further enhance the sealing performance of the device, reduce gas leakage between the slide rod and the sliding hole, and between the conical block and the furnace opening, better maintain the experimental atmosphere and temperature stability in the furnace, and improve the accuracy and reliability of the experiment.

[0010] Furthermore, the sum of the lengths of the tray and the slide bar is greater than the length of the furnace chamber, ensuring that the tray can extend out of the furnace chamber, making it convenient for operators to place and retrieve samples, and improving the ease of operation.

[0011] Furthermore, the width of the tray is smaller than the width of the furnace chamber, allowing the tray to move smoothly within the furnace chamber and avoiding friction or collision between the tray and the inner wall of the furnace chamber due to the tray being too wide, which would affect the normal operation of the tray and the conduct of the experiment.

[0012] Furthermore, the furnace body is provided with a three-pronged pipe on its side, and one end of the three-pronged pipe is connected to the gas tank. The other two ends of the three-pronged pipe are respectively connected to a vacuum pump and an air pump through a one-way valve. By connecting the vacuum pump and the air pump, the furnace can be easily evacuated or filled with gas to meet the diverse atmospheric requirements of different experiments. For example, it can create vacuum conditions for experiments that require an oxygen-free environment, or introduce a specific gas for a specific experiment.

[0013] Furthermore, the number of furnace chambers is no less than eight, and the number of furnace chambers, pushers, and furnace doors is consistent. A larger number of furnace chambers greatly increases the throughput of experiments, allowing multiple experiments under different conditions to be conducted simultaneously, accelerating the experimental progress and improving experimental efficiency. The consistent number of components ensures that each furnace chamber can operate independently and normally without interfering with each other.

[0014] Compared with existing technologies, the beneficial effects of this utility model are as follows: This fully automatic high-throughput multi-station high-temperature experimental furnace features a multi-furnace chamber design to achieve multi-station operation, with no fewer than eight furnace chambers, allowing for simultaneous testing of multiple samples. Compared to single-station experimental furnaces, in experiments such as researching the sintering process of novel ceramic materials, which requires testing the performance of different formulations at different temperatures, it can significantly reduce experimental time from several days or weeks to a shorter cycle, accelerating the experimental progress and improving overall experimental efficiency. Furthermore, the consistent number of furnace chambers, pushers, and furnace doors ensures that each furnace chamber can operate independently and normally without interference, further increasing the experimental throughput.

[0021] 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.

[0022] Please see Figures 1-5 This utility model provides a technical solution: a fully automatic high-throughput multi-station high-temperature experimental furnace, including a furnace body 1, the furnace body 1 having several furnace chambers 12 inside, each furnace chamber 12 having an opening, and a furnace door 4 located near the opening on the outer side of the furnace body 1, the furnace door 4 sealing the opening, the furnace chamber 12 having heating wires and temperature sensors installed inside, and a tray 9 suspended inside each furnace chamber 12, the furnace body 1 also having a pusher that drives the tray 9 to move horizontally, the free end of the tray 9 being connected to the furnace door 4, the furnace body 1 also having a gas groove 11 inside, and a solenoid valve 13 connecting the furnace chamber 12 and the gas groove 11, the furnace chamber 12 also having a high-temperature pressure sensor installed inside, multiple furnace chambers 12 can simultaneously conduct experiments under different or the same conditions, when the furnace door 4 is closed, it seals the furnace chamber opening to prevent heat and gas leakage; when open, it cooperates with the pusher to transfer samples. The temperature sensor monitors the temperature and feeds it back to the control system, adjusting the heating wire power to control the temperature. The pusher pushes the tray 9 to move horizontally, realizing the entry and exit of samples from the furnace chamber. Gas trough 11, solenoid valve 13 and high temperature pressure sensor work together to control the opening and closing of solenoid valve to introduce or discharge gas into the furnace and regulate the atmosphere and pressure.

[0023] As one embodiment of this utility model, the pushing component further includes an electric telescopic rod 3 installed on the back of the furnace body 1. A sliding hole 8 is provided inside the furnace body 1, communicating with the furnace chamber 12. A sliding rod 10 slides inside the sliding hole 8. The telescopic end of the electric telescopic rod 3 is connected to the sliding rod 10, and the tray 9 is connected to the free end of the sliding rod 10. When the electric telescopic rod 3 is energized, its telescopic end extends or retracts according to a control command. When retracted, it pushes the sliding rod 10 to slide within the sliding hole 8, causing the sliding rod to move the tray 9 into the furnace chamber 12, thus sending the sample into the furnace chamber. When extended, it pushes the sliding rod and the tray to move in opposite directions, thereby opening the furnace door 4, allowing the user to simultaneously remove the sample.

[0024] As an embodiment of this utility model, the furnace door 4 is further provided with a conical block 6 on the side near the furnace body 1. The shape of the opening matches the conical block 6. The radius of the conical block 6 on the side near the furnace body 1 is greater than the radius on the side away from the furnace body 1. When the furnace door 4 is closed, the conical block 6 is inserted into the opening of the furnace chamber 12. Due to the special shape of the conical block, as the furnace door is closed, the gap between the conical block and the opening gradually decreases, forming a tight sealing structure to prevent heat and gas leakage.

[0025] As an embodiment of this utility model, a first sealing ring 5 is installed on the outer side of the slide rod 10, and a second sealing ring 7 is installed on the outer side of the conical block 6. The first sealing ring 5 fills the gap between the slide rod 10 and the sliding hole 8 to prevent gas from leaking from the gap; the second sealing ring 7 fills the tiny gap between the conical block 6 and the furnace opening to prevent gas leakage in the furnace and ensure the stability of the atmosphere and pressure in the furnace.

[0026] As an embodiment of this utility model, the combined length of the tray 9 and the slide bar 10 is greater than the length of the furnace chamber 12. Since the combined length of the tray 9 and the slide bar 10 is greater than the length of the furnace chamber 12, the tray 9 can extend out of the furnace chamber 12 under the action of the electric telescopic rod 3, providing sufficient space for loading and unloading samples.

[0027] As an embodiment of the present invention, the width of the tray 9 is smaller than the width of the furnace chamber 12. The smaller width of the tray 9 ensures that it will not be obstructed by the inner wall of the furnace chamber 12 when it moves horizontally inside the furnace chamber 12, thus ensuring that the tray 9 can smoothly enter and exit the furnace chamber 12.

[0028] As an embodiment of this utility model, the furnace body 1 is further provided with a three-way pipe 2 on its side, and one end of the three-way pipe 2 is connected to the gas groove 11. The other two ends of the three-way pipe 2 are connected to a vacuum pump and an air pump respectively through a one-way valve. When a vacuum is required, the vacuum pump evacuates the furnace chamber 12 through the three-way pipe 2 and the gas groove 11. When gas is required, the air pump fills the furnace chamber 12 with gas through the three-way pipe 2 and the gas groove 11. The solenoid valve 13 controls the gas flow between the gas groove 11 and the furnace chamber 12.

[0029] As an embodiment of this utility model, the number of furnace chambers 12 is not less than eight, and the number of furnace chambers 12, pushers, and furnace doors 4 is the same. Each furnace chamber 12 is equipped with an independent pusher and furnace door 4. The operator can control the corresponding components of each furnace chamber 12 according to the experimental requirements, so as to realize the simultaneous experimentation of different samples under different conditions.

[0030] It should be noted that all standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control method is automatic control through a control cabinet. The control circuit can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Furthermore, since this application is mainly used to protect mechanical devices, this application will not explain the control method and circuit connection in detail.
