Description

Technical Field

[0001] This utility model relates to the field of laboratory high-temperature reaction vessel technology, and in particular to a laboratory high-temperature heating furnace. Background Technology

[0002] This technology relates to a high-temperature heating furnace (reactor) used in laboratories to conduct chemical reactions under high-temperature conditions. It is widely applied in chemical engineering, materials science, biomedicine, and the food industry. Currently, traditional high-temperature heating furnaces are all at high temperatures, such as the utility model patent CN206911347U entitled "A Simple-to-Operate Parallel High-Temperature Reaction Vessel for Laboratory Use." This furnace includes a housing with a control panel fixed to its left side wall. A protective cover is bolted to the top of the housing, and a vessel mounting bracket is bolted to the bottom of the cover. The vessel body is inserted into the top of the mounting bracket, and a high-pressure cover is bolted to the top of the vessel body. An electric heater is placed between the mounting bracket and the vessel body, resulting in both the surface and interior of the vessel body being at high temperatures. In the laboratory, the high temperature of the vessel body can easily cause burns to operators due to accidental contact; simultaneously, the heat from the high-temperature vessel body dissipates into the laboratory, raising the ambient temperature.

[0003] Therefore, there is an urgent need to develop a laboratory high-temperature heating furnace with a simple structure and reliable thermal insulation. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide a high-temperature laboratory heating furnace. The technical solution adopted by this utility model is as follows:

[0005] A laboratory high-temperature heating furnace includes a heat dissipation box, an operating platform mounted on the heat dissipation box, a condensate circulation jacket fixed to the heat dissipation box, an inner furnace body with its upper part fitted inside the condensate circulation jacket and its lower part placed inside the heat dissipation box, an inlet pipe and an outlet pipe mounted on the condensate circulation jacket, an upper cover covering the inner furnace body, a heating furnace body mounted inside the heat dissipation box and fitted at the lower part of the inner furnace body, a heater positioned between the inner furnace body and the heating furnace body, a first thermocouple sheath, a second thermocouple sheath, a displacement gas inlet, and a displacement gas outlet mounted on the upper cover, a winding roller positioned inside the inner furnace body, a heat insulation block positioned in the middle of the inner furnace body, and a heat insulation layer positioned between the heat insulation block and the upper cover; the first thermocouple sheath penetrates the heat insulation block and is positioned inside the winding roller; the second thermocouple sheath penetrates the heat insulation block and is positioned outside the winding roller; the displacement gas inlet and outlet are connected to the heat insulation layer; and the inlet pipe and outlet pipe are connected to external cooling water.

[0006] Furthermore, the heat dissipation box is provided with an inner groove; the condensate circulation jacket and the inner furnace body are installed in the inner groove.

[0007] Furthermore, the upper cover is provided with several lifting lugs.

[0008] Compared with the prior art, the present invention has the following beneficial effects:

[0009] (1) The present invention provides a heater in the heat dissipation box to heat the inner furnace body so that the lower part of the inner furnace body reaches the reaction zone temperature required by the experiment. The upper part of the inner furnace body is cooled and insulated by the heat insulation block and the condensate circulation water jacket to form a heat insulation layer, which effectively prevents heat transfer to the upper end cover. This can meet the high temperature heating needs of the lower part of the inner furnace body and prevent heat transfer to the upper end cover.

[0010] (2) By setting up a heat insulation block, a condensate circulation jacket, a displacement gas inlet and a displacement gas outlet, this utility model reduces the temperature at the top cover and reduces the heat directly dissipated from the reactor to the laboratory.

[0011] (3) This utility model sets up a first thermocouple sleeve and a second thermocouple sleeve, and inserts thermocouples in them respectively to measure the temperature inside and outside the winding roller, so as to ensure reliable monitoring of heating temperature.

[0012] In summary, this utility model has the advantages of simple structure and reliable heat insulation, and has high practical and promotional value in the field of laboratory high-temperature reaction vessel technology. Attached Figure Description
