Description

Technical Field

[0001] This utility model relates to the field of laboratory heating equipment technology, specifically to a sample heating furnace. Background Technology

[0002] Heating equipment used to remove moisture or organic matter from the sample surface is a common pretreatment tool in laboratories and industrial production. Its core principle is to create a constant temperature environment through electric heating elements (such as electric heating tubes), and use heat conduction and heat convection to make the moisture or low-boiling-point organic matter on the sample surface absorb heat and evaporate.

[0003] The heating stage widely used in existing laboratories as the main heating equipment often takes a long time to start, stop and heat up. It often takes several minutes or even longer to heat up from room temperature to the target temperature required for the experiment, which greatly extends the preparation cycle of a single experiment. At the same time, the heat conduction efficiency is low, and the heat is easily unevenly distributed when it is transferred to the sample through the stage, which affects the consistency of the experimental reaction and the accuracy of the results, thus slowing down the overall research process.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0028] like Figures 1-2 As shown, in one embodiment, a sample heating furnace includes: a placement assembly 1 and a heating assembly 2;

[0029] The placement component 1 is used to stably place various samples to be heated, while the heating component 2 is used to continuously provide a stable heat supply to the samples, ensuring that the samples can complete the heating process under the set conditions.

[0030] For example, the placement assembly 1 includes a placement rack 11, which is provided with a raising pad 12 to provide a stable support platform for the sample tray 3, so that the sample tray 3 can be placed in a horizontal state.

[0031] Correspondingly, the heating component 2 includes a heat-resistant brick 21 with excellent high-temperature resistance. A heating wire 22 is provided on its surface or inside. The heating wire 22 serves as the core heating element, which can rapidly heat up and radiate heat to the surroundings after being powered on, providing an energy source for heating the sample.

[0032] Specifically, the heat-resistant brick 21 is placed on the placement rack 11, and the heat-resistant brick 21 has a receiving groove 211;

[0033] Correspondingly, the heating wire 22 extends along the internal path of the receiving groove 211 to ensure that the heating wire 22 is in close contact with the heat-resistant brick 21, thereby improving the heat transfer efficiency. At the same time, the heating wire 22 is connected to the external power supply through the wire to achieve a stable electrical connection, ensuring the continuity and safety of the power supply.

[0034] Furthermore, the placement rack 11 includes a stainless steel support frame 111, and the ends of the support frame 111 are welded to stainless steel support legs 112 by welding process, which can significantly improve the connection strength between the support frame 111 and the support legs 112, and ensure that the overall structure of the placement rack 11 is stable and reliable.

[0035] In addition, a heightening pad 12 is installed on the top of the support frame 111 for placing the sample tray 3 containing the sample.

[0036] Specifically, the heightening pad 12 is made of ceramic, which has good high temperature resistance; and the heightening pad abuts against the sample tray 3, with 4-6 sets of heightening pads 12 symmetrically arranged.

[0037] Understandably, when the sample plate 3 is placed on the contact point of the raising pad 12 and the heating wire is connected to the power supply, the current passes through the heating wire 22 and continues to generate heat due to the resistance effect. The heat is quickly transferred to the sample plate 3 through the heat-resistant brick 21, so that the sample gradually heats up in a suitable temperature environment, thereby causing the moisture, organic matter and other impurities attached to the sample surface and inside to absorb heat and evaporate.

[0038] Please continue reading. Figures 3-4 In this embodiment, the placement component 1 and the heating component 2 are placed inside the furnace body 4. The furnace body 4 can provide a good heat preservation environment for the internal components and reduce heat loss. A special support frame 41 is provided at the bottom of the furnace body 4, and the placement frame 11 is placed stably on the support frame 41.

[0039] For example, a handle 411 is provided at the end of the receiving frame 41, so that the experimenter can easily pull or move the receiving frame 41;

[0040] Correspondingly, a placement groove 412 is provided in the middle of the receiving frame 41, and the bottom of the placement frame 11 is inserted into the placement groove 412, thereby effectively limiting the displacement of the placement frame 11 and ensuring its stability during the heating process.

[0041] Through the above technical solution, the close integration and reasonable layout of the heating wire 22 and the heat-resistant brick 21 greatly improve the heat conduction speed, and the heat can be quickly transferred to the sample; at the same time, the efficient heating characteristics of the heating wire 22 enable the equipment to heat up quickly, shortening the experimental preparation time; in addition, the components have simple structures and reliable connections, and the replacement of easily damaged parts such as the heating wire 22 is convenient, which greatly reduces the maintenance cost of the equipment.

[0042] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
