Abstract
Description
Technical Field
[0001] This utility model relates to the field of experimental atmosphere furnace technology, specifically a partitioned structure for the heating tubes of a dual-tube vertical thermogravimetric atmosphere furnace. Background Technology
[0002] During the use of experimental atmosphere furnaces, the heated materials usually undergo physicochemical reactions at high temperatures, releasing fumes and gases that are harmful to humans and the environment. Experimental atmosphere furnaces can perform high-temperature heat treatment on materials under the protection of inert gases such as nitrogen and argon, avoiding oxidation of the materials and preparing high-purity samples. Therefore, they have become commonly used heat treatment experimental equipment in the fields of chemistry, chemical engineering, and materials science.
[0003] For example, the Chinese patent with publication number CN213668324U, entitled "(An Experimental Atmosphere Furnace Flue Gas Treatment Device)," includes: a cylindrical body, a filter assembly, and an exhaust assembly. The cylindrical body is equipped with a flue gas inlet pipe, and the cylindrical body contains a lower first limiting block and an upper second limiting block. The filter assembly is located within the cylindrical body above the flue gas inlet pipe, and includes a first filter structure and a second filter structure. This invention effectively purifies the flue gas generated by the experimental atmosphere furnace, preventing direct emission of the flue gas into the external environment and avoiding significant harm to experimental personnel and the environment. It employs a dual purification process using graphene carbon blocks and activated carbon blocks to ensure the cleanliness of the treated flue gas. Furthermore, the inclusion of a second stainless steel mesh inside the cylindrical body facilitates the replacement of the activated carbon blocks and graphene carbon blocks.
[0004] However, existing experimental atmosphere furnaces cannot adjust the heating environment according to the reaction status of the materials during use; therefore, they do not meet the current requirements. To address this, we propose a dual-tube vertical thermogravimetric atmosphere furnace with partitioned heating tube structure. Utility Model Content
[0005] The purpose of this invention is to provide a dual-tube vertical thermogravimetric atmosphere furnace heating tube partition structure to solve the problem mentioned in the background art that existing experimental atmosphere furnaces cannot adjust the heating environment according to the reaction status of the materials during use.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a partitioned structure for the heating tubes of a double-tube vertical thermogravimetric atmosphere furnace, comprising: a double-tube vertical atmosphere furnace, wherein double-tube furnace bodies are provided inside both ends of the double-tube vertical atmosphere furnace, and two double-tube furnace bodies are provided.
[0007] Also includes:
[0008] The first inner cavity is installed below the interior of the dual-tube vertical atmosphere furnace. A feeding rod is provided on one side of the first inner cavity.

A support rod is provided at the middle position of the upper end face of the feeding rod, and the support rod passes through the connecting base plate and extends to the outside of the upper installation base. A temperature monitoring mechanism is provided between the connecting base plate and the outer wall of the support rod.
[0009] The second inner cavity is installed above the interior of the dual-tube furnace body. The interior of the second inner cavity is provided with a ceramic inner tube. Several ceramic inner tubes are provided, and several ceramic inner tubes are detachable and installable. A heating tube is provided around the outer wall of several ceramic inner tubes.
[0010] Preferably, a lifting moving rod mechanism is provided on one side of the feeding upright, and a horizontal moving rod mechanism is provided on the rear side of the lifting moving rod mechanism. A connecting bracket is provided between the lifting moving rod mechanism and the feeding upright, and both sides of the connecting bracket are threadedly connected to the feeding upright and the horizontal moving rod mechanism.

[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1. This utility model, through the setting of a feeding upright, a lifting moving rod mechanism, and a horizontal moving rod mechanism, as well as a ceramic bowl and a temperature monitoring mechanism set on the feeding upright, allows the material to be placed inside the ceramic bowl. The lifting moving rod mechanism is then reset and lowered, and the horizontal moving rod mechanism is moved to drive the lifting moving rod mechanism, so that the upper end of the feeding upright is directly below the ceramic inner tube. During the reaction operation, the heating tube is turned on to heat the ceramic inner tube. Simultaneously, an external reaction atmosphere is added into the ceramic inner tube to support the material's reaction. The required temperature varies depending on the material's state. The temperature monitoring mechanism monitors the temperature in real time, allowing the feeding upright to move up and down as needed. When a higher temperature is required, the feeding upright is moved upwards; when a higher temperature is not needed, it is moved downwards. This effectively avoids the problem of existing experimental atmosphere furnaces being unable to adjust the heating environment according to the material's reaction status.

An mounting base 10403 is provided above the connecting base plate 10404. A support rod 10402 is provided at the middle position of the upper end face of the feeding rod 104. The support rod 10402 passes through the connecting base plate 10404 and extends to the outside of the mounting base 10403. A temperature monitoring mechanism 10405 is provided between the connecting base plate 10404 and the outer wall of the support rod 10402.
[0026] The second inner cavity 204 is installed above the inside of the double-tube furnace body 200. The second inner cavity 204 is provided with a ceramic inner tube 205. Several ceramic inner tubes 205 are provided. Several ceramic inner tubes 205 can be detached and installed. A heating tube 206 is provided around the outer wall of several ceramic inner tubes 205.
[0027] The feeding upright 104 and the vertical ceramic inner tube 205 are configured such that the feeding upright 104 can be moved up and down as needed for the material. When a high temperature is required, the feeding upright 104 is moved upward, and when a high temperature is not required, the feeding upright 104 is moved downward.
[0028] Example 2
[0029] Please see Figure 2 A lifting moving rod mechanism 103 is provided on one side of the feeding upright 104, and a horizontal moving rod mechanism 106 is provided on the rear side of the lifting moving rod mechanism 103. A connecting bracket 105 is provided between the lifting moving rod mechanism 103 and the feeding upright 104. Both sides of the connecting bracket 105 are threadedly connected to the feeding upright 104 and the horizontal moving rod mechanism 106. A ceramic bowl 10401 is provided on the upper end face of the support rod 10402.
[0030] The ceramic bowl 10401 is designed to effectively provide a reaction space cavity for materials that need to react.
[0031] Please see Figure 1The two double-tube furnace bodies 200 are provided with an outer protective cover 101, and the outer protective cover 101 is fixedly connected to the double-tube vertical atmosphere furnace 100. The upper end face of the two double-tube furnace bodies 200 is provided with a conveying mechanism 201. A discharge pipe 203 is provided on one side above the conveying mechanism 201. A conveying pipe 202 is provided between the discharge pipe 203 and the conveying mechanism 201.

During the reaction operation, the heating tube 206 is turned on to heat the ceramic inner tube 205. At the same time, the external reaction atmosphere is added into the ceramic inner tube 205 to support the reaction operation of the material. The required temperature varies depending on the state of the material. The temperature varies depending on the depth of the ceramic inner tube 205. The temperature increases from bottom to top according to the depth of the ceramic inner tube 205. The temperature monitoring mechanism 10405 monitors in real time and can move the feeding rod 104 up and down as needed by the material. When a high temperature is needed, the feeding rod 104 is moved upward, and when a high temperature is not needed, the feeding rod 104 is moved downward. Because the ceramic inner tube 205 is vertical, the temperature of the internal cavity is concentrated at the top, while the temperature at the bottom is relatively low.
