Description
Technical Field
[0001] This utility model belongs to the field of vacuum heating technology, and in particular relates to a vacuum heating device that is easy to insulate. Background Technology
[0002] In modern industrial production, vacuum heating devices are widely used in many industries, such as materials processing, chemical synthesis, and electronic component manufacturing, due to their advantages of providing a stable high-temperature environment and preventing oxidation. For example, in the semiconductor chip manufacturing process, vacuum heating devices are needed to perform precise heat treatment on wafers to achieve specific physical and chemical changes; in the research and development of new materials, the vacuum heating environment helps to synthesize materials with special properties.
[0003] Currently, the loss of a large amount of heat during the operation of existing vacuum heating devices not only wastes energy and increases production costs, but also causes the ambient temperature around the device to rise, posing safety hazards to operators and affecting the normal operation of surrounding equipment. On the other hand, the poor heat insulation makes it difficult to control the internal temperature of the heating device stably, failing to meet the requirements of high-precision production processes, and thus affecting product quality and production efficiency.
[0004] To address these issues, we provide a vacuum heating device that is easy to insulate. Utility Model Content
[0005] The purpose of this invention is to provide a vacuum heating device that is easy to insulate. By combining the insulation component and the heating wire component, it solves the problem that the vacuum heating device in the prior art has poor insulation, which makes it difficult to control the internal temperature of the heating device stably and cannot meet the requirements of high-precision production processes.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.
[0007] This utility model relates to a vacuum heating device with convenient heat insulation, comprising a heat insulation component. A heating wire assembly is disposed on the top of the heat insulation component. The heating wire assembly includes a disc-shaped heating wire, which is positioned on the top of the heat insulation component. A positioning seat is fixedly connected to the bottom of the disc-shaped heating wire. A housing is fixedly connected to the bottom of the positioning seat. A wiring terminal is fixedly connected to the bottom of the positioning seat, extending to the inner cavity of the housing. An integrated connector is connected to the bottom of the housing. The heat insulation component includes a heat insulation plate with a four-layer structure. A heat insulation wire assembly is fixedly connected to the top of the heat insulation plate. The heating wire assembly uses the disc-shaped heating wire as the core heating element, and the main filling material inside the disc-shaped heating wire is oxide. Magnesium, with its excellent high-temperature resistance and insulation properties, ensures stable operation of the disc heating wire at temperatures up to 750°C, providing a reliable high-temperature heat source for the device. The positioning base not only supports and fixes the disc heating wire but also provides a mounting foundation for components such as wiring terminals. The outer shell connected to the bottom of the positioning base protects the internal wiring terminals and other electrical components from external factors such as dust and moisture affecting their electrical performance. The wiring terminals are fixed to the bottom of the positioning base, extending into the inner cavity of the outer shell, and are connected to the disc heating wire via wires to achieve power transmission. The integrated connector connected to the bottom of the outer shell adopts an integrated design of wiring terminals and dedicated aviation plugs, supporting both 220V and 380V voltage inputs to meet the power needs of different usage scenarios.
[0008] The present invention is further configured such that a fixing frame is fixedly connected to the top of the disc heating wire, and the number of fixing frames is three, and the three fixing frames are equally distributed. The fixing frames are used to install and position the disc heating wire. The equally distributed method can effectively limit its unreasonable displacement and avoid the heating wire from twisting or breaking due to excessive local stress, thus ensuring the structural integrity and stability of the heating wire.
[0009] The present invention is further configured such that a bolt is provided on the top of the fixing frame, and a washer is fitted on the bottom of the bolt. The bolt can tightly connect the fixing frame and the heat insulation plate, providing a strong fastening force. The washer can increase the contact area between the bolt and the fixing frame and disperse the pressure generated when the bolt is tightened.
[0010] The present invention is further configured such that a positioning post is fixedly connected to the top of the heat insulation plate, the positioning post being compatible with the bolt, and during installation, the positioning post can provide positioning guidance for the bolt, enabling the operator to quickly install the disc heating wire into the predetermined position.
[0011] The present invention is further configured such that the heat insulation wire device includes a heating wire baffle, the bottom of which contacts the heat insulation plate, and a heat insulation frame is fixedly connected to the top of the heating wire baffle. The heating wire baffle and the heat insulation plate are in close contact, providing a stable support foundation for the heat insulation frame, so that the heat insulation frame can be stably set between the heating wire baffle and the disc heating wire. The heat insulation frame further blocks the conduction of heat from the disc heating wire to the heating wire baffle, effectively avoiding problems such as deformation and aging of the heating wire baffle due to high temperature, and extending the service life of the heating wire baffle.
[0012] The present invention is further configured such that mounting plates are fixedly connected to both sides of the bottom of the heat insulation plate, and one side of the mounting plate is fixedly connected to the positioning seat. The mounting plates firmly connect the heat insulation plate and the positioning seat, so that the heat insulation component and the heating wire component form a tightly integrated whole structure.
[0013] The present invention is further configured such that a first positioning pin is provided on the top of each mounting plate, the mounting plate is fixedly connected to the heat insulation plate through the first positioning pin, and a second positioning pin is provided on both sides of the mounting plate. One side of the second positioning pin is fixedly connected to the positioning seat, the first positioning pin is fixedly connected to the heat insulation plate, and the second positioning pins on both sides are fixedly connected to the positioning seat, thereby ensuring the stability of the installation position.
[0014] The present invention has the following beneficial effects.
[0015] 1. This utility model adopts a four-layer heat insulation board, combined with a top heat insulation wire device, to form a multi-layer composite heat insulation system. This system can greatly hinder heat transfer and effectively reduce the heat loss from the heating wire assembly to the outside. This not only reduces energy consumption but also keeps the ambient temperature around the device within a safe range, preventing operators from being burned and ensuring the normal operation of other instruments around the device. At the same time, it ensures the internal temperature of the heating device is stable, meeting the temperature stability requirements of high-precision production processes.
[0016] 2. This utility model utilizes the disc-shaped structure of the heating wire to ensure uniform heat distribution. Combined with the bottom positioning seat, outer shell, wiring terminals, and integrated connector, it ensures the stability and safety of the heating wire during operation. The disc-shaped heating wire is tightly connected to the positioning post on the heat insulation component through the fixing frame, bolts, and gaskets, further enhancing the fixing effect of the heating wire and preventing displacement of the heating wire due to vibration or other factors during heating. This ensures the uniformity and stability of heating and provides a reliable heat source for the production process. Attached Figure Description
