Description

Technical Field

[0001] This utility model relates to the field of muffle furnaces, and more particularly to a muffle furnace for rapid heating and heat dissipation. Background Technology

[0002] Muffle furnaces are devices used for high-temperature material processing. Rapid heating and cooling muffle furnaces, through optimized heating elements, furnace structure, and heat dissipation system, coupled with intelligent control algorithms, can complete heating and cooling in a short time. Compared with traditional equipment, they can shorten the experimental cycle by more than 50%. At the same time, through multi-zone heating and precise temperature control, the temperature uniformity error is controlled within ±2℃, which reduces the performance degradation of samples caused by prolonged high temperature, reduces heat loss by 30%, and improves the safety of automated operation. They are widely used in scenarios with high requirements for efficiency and precision, such as lithium battery material sintering, semiconductor annealing, and metal heat treatment.

[0003] The muffle furnace, designed for rapid heating and cooling, utilizes high-density heating elements and a multi-faceted surround layout, combined with a PID composite control algorithm, to achieve rapid heating at rates exceeding 20℃ / min, while keeping temperature overshoot within ±3℃. During cooling, forced air cooling, heat absorption by phase change materials, and a pneumatic pressure relief valve work together to achieve a cooling rate of 15℃ / min, reducing the temperature from 800℃ to 100℃ in just 40 minutes. Simultaneously, the multi-layer composite insulation structure and dynamic sealing design reduce heat loss by 30%, ensuring the safe and stable operation of the furnace and meeting the demands for efficient and precise temperature control in material preparation and other scenarios.

[0004] In the actual use of muffle furnaces for rapid heating and cooling, the maintenance challenges of the cooling system are particularly prominent. Currently, most equipment uses a fixed, integrated design for the cooling pipes, with the transport pipes and cooling lines rigidly connected by threads or flanges. Disassembly requires the use of wrenches, screwdrivers, and other tools to disassemble the furnace shell, insulation layer, and pipe connections layer by layer. A single cleaning process can take 2-3 hours. If scale forms inside the cooling pipes due to high water hardness or sample residue buildup, clogging the channels, the cooling rate will not only drop from 15℃ / min to below 8℃ / min, but uneven heat dissipation can also cause localized overheating and damage to the heating elements. This complex maintenance not only interrupts equipment operation but also requires professional intervention, directly impacting the continuous operating efficiency of the equipment. This contradicts the original design intent of rapid heating and cooling, becoming a key bottleneck restricting the equipment's high efficiency. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a muffle furnace for rapid heating and heat dissipation, aiming to improve the problem that requires complicated operations to remove the transport pipe and clean the inside of the cooling pipe during equipment use.

[0014] As a further description of the above technical solution:

[0032] 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.

[0033] Reference Figures 1-3 The present invention provides an embodiment of a muffle furnace for rapid heating and heat dissipation, comprising a base 1, a furnace body 2 fixedly connected to the top of the base 1 for heating items, a sealing component provided on one side of the furnace body 2 for sealing the furnace body 2, a heating component provided inside the furnace body 2 for providing heat to the items, heat dissipation components provided inside both the base 1 and the furnace body 2 for extracting heat from the equipment after the equipment is stopped, a return pipe 10 fixedly connected inside the furnace body 2 for returning cooling water, an inlet pipe 11 fixedly connected inside the furnace body 2 for flowing cooling water, a fixing component provided on the outer wall of the inlet pipe 11, a transport pipe 17 slidably connected inside the inlet pipe 11 for transporting cooling water, and a fixing groove 18 provided on the outer wall of the transport pipe 17;

[0034] The fixing assembly includes a sliding sleeve 12, a fixing ring 13, and a spring 14. The inner wall of the sliding sleeve 12 is slidably connected to the outer wall of the inlet pipe 11 to control the position of the balls 15. The inner wall of the fixing ring 13 is fixedly connected to the outer wall of the inlet pipe 11 to limit the movement range of the sliding sleeve 12. The spring 14 is disposed inside the sliding sleeve 12 to provide elastic force to the sliding sleeve 12. One end of the spring 14 is fixedly connected inside the sliding sleeve 12, and the other end of the spring 14 is fixedly connected to one side of the fixing ring 13. Multiple balls 15 are slidably connected inside the inlet pipe 11 and cooperate with the fixing groove 18 to fix the transport pipe 17. Multiple sliding grooves 16 are opened inside the inlet pipe 11 to accommodate the balls 15. The sealing assembly includes a furnace door 3 and a handle 4. The furnace door 3 is rotatably connected to one side of the furnace body 2 to seal the furnace body 2. The handle 4 is fixedly connected to one side of the furnace door 3 to open and close the furnace body 2. The heating assembly includes a furnace wall 5 and multiple heating tubes 8. The outer wall of the furnace wall 5 is fixedly connected to the inside of the furnace body 2 to place items to be heated and conduct heat for heating. Both ends of each heating tube 8 are fixedly connected to the inside of the furnace body 2 to emit heat to heat the items. The heat dissipation assembly includes multiple heat dissipation holes 6, multiple fans 7, and cooling pipes 9. The heat dissipation holes 6 are opened inside the base 1 to accommodate the fans 7. The outer wall of the fans 7 is fixedly connected to the inside of the heat dissipation holes 6 to extract heat from the inside of the furnace body 2. The outer wall of the cooling pipes 9 is fixedly connected to the inside of the furnace body 2.

[0035] Specifically, during maintenance, the operator must first firmly grasp the sliding sleeve 12 with both hands, and then push it inward with even and stable force. As the sliding sleeve 12 moves, the ball bearing 15, which was originally firmly embedded in the fixed groove 18, slowly retracts under the leverage and smoothly disengages from the groove. The transport tube 17 is thus released from mechanical locking. At this time, by holding the transport tube 17, the front end can be easily and smoothly pulled out from the tightly nested interface of the inlet tube 11. After disassembly, the sliding sleeve 12 is released, and the built-in high-elasticity spring 14 immediately releases its stored energy, causing the sliding sleeve 12 to precisely reset, and the ball bearing 15 to re-enter the fixed groove 18. The whole process is as smooth as flowing water, opening a convenient channel for subsequent cleaning of the cooling tube 9.

[0036] Reference Figure 4 and Figure 5The base 1 has multiple connecting rods 19 fixedly connected to its bottom for connecting the support rods 20 and the base 1. Each connecting rod 19 has a support rod 20 slidably connected to its outer wall for supporting the entire device. Each support rod 20 has multiple connecting holes 21 on its outer wall for accommodating fixing pins 22. Each support rod 20 has a support base 25 fixedly connected to its bottom for supporting the entire device. Each connecting rod 19 has a fixing pin 22 slidably connected to its bottom end for fixing the height of the device. Each fixing pin 22 has its outer wall slidably connected inside the connecting hole 21. Each fixing pin 22 has a limit plate 23 fixedly connected to one end to limit the movement range of the fixing pin 22. Each limit plate 23 has a pull ring 24 fixedly connected to one side for driving the fixing pin 22 to move.

[0037] Specifically, when adjusting the equipment height, the operator places their palm on the pull ring 24 and then pulls it outward with a steady and moderate force. As the pull ring 24 moves, the fixing pin 22, which was originally firmly embedded in the positioning hole of the connecting rod 19, slowly comes out. At this time, the connecting rod 19 is successfully unlocked. Then, holding the support rod 20, the operator can use its comfortable grip arc to precisely adjust the equipment height according to the actual usage needs. After the height is determined, the fixing pin 22 is aligned with the corresponding height of the connecting hole 21 and gently pushed in. When the fixing pin 22 re-engages in the connecting hole 21, the familiar locking sound is heard again. The entire adjustment process is completed in one go, ensuring that the equipment stands stably at the ideal height, providing reliable support for subsequent operations.

[0038] Working principle: When using the muffle furnace for rapid heating and heat dissipation, first hold the pull ring 24 and pull it outward to disengage the fixing pin 22 from the inside of the connecting rod 19, thereby unlocking the connecting rod 22. Then, hold the support rod 20 to adjust the height of the entire equipment to the required height, and then insert the fixing pin 22 into the corresponding connecting hole 21. When it is necessary to remove the transport pipe 17 to clean the cooling pipe 9, first hold the sliding sleeve 12 and push it inward to unlock the ball bearing 15 and disengage it from the fixing groove 18, thereby unlocking the transport pipe 17. Then, hold the transport pipe 17 and pull its front end out from the inlet pipe 11. Finally, release the sliding sleeve 12 so that it returns to its original position under the action of the spring 14.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
