Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of drying ovens, and in particular to an electric heating constant temperature drying oven for foam glass production experiments. Background Art
[0002] Foam glass is a new type of inorganic thermal insulation material made primarily from glass, by adding an appropriate amount of foaming agent, and then undergoing high-temperature heating, roasting, and annealing. Foam glass has low density, low thermal conductivity, is impermeable to moisture, does not absorb water, does not burn, and does not mold. It also possesses high mechanical strength and excellent chemical stability. It can withstand all chemical attacks except hydrogen fluoride and maintains stable performance over a wide temperature range from ultra-low to high temperatures. During the production of foam glass, the experimental stage is crucial for optimizing material formulations and production processes. Therefore, electric constant-temperature drying ovens play a vital role in experimental research on foam glass, providing a stable drying environment to test and evaluate the performance of foam glass under different conditions.
[0003] In the prior art, in order to provide a stable drying environment to test and evaluate the performance of foam glass under different conditions, an electric constant temperature drying oven is generally used. However, during the application of the constant temperature drying oven, there is a problem that the position where the hot air is provided is relatively fixed. For foam glass samples placed at different positions in the box, their heating state will be directly affected by the temperature distribution in the box. Samples close to the heat source may dry prematurely or even be damaged, while samples far away from the heat source may dry later, resulting in different heating conditions of the materials in different places in the box, resulting in certain differences in the drying degree of the materials, thereby reducing the accuracy and reliability of the experimental data. Utility Model Content
[0004] The utility model provides an electric constant temperature drying oven for foam glass production experiments, which solves the problem that the position of hot air provided by the constant temperature drying oven in the related art is relatively fixed during application.

[0013] The working principle and beneficial effects of the utility model are as follows:
[0014] 1. In the utility model, the servo motor is started to drive the turntable to rotate, and the turntable drives the thin rod to rotate. When the thin rod rotates, it drives the hollow frame to move up and down to perform reciprocating motion. Under the action of the limit block, the hollow frame drives the connecting rod to move synchronously. The movement of the connecting rod simultaneously drives the adjusting rod to slide inside the guide frame, so that the guide frame drives the air outlet pipe to rotate back and forth, thereby changing the air outlet direction of the air outlet pipe, expanding the drying range of the air outlet pipe, making the material heated more evenly, and improving the reference value of the experimental data.

When the cam does not push the I-frame, the spring pushes the I-frame to reset, and the I-frame drives the U-frame to clean the filter again, avoiding clogging of the filter caused by excessive dust, thereby improving the practicality of the device.

The purpose of this arrangement is that, when in use, the foam glass to be dried is placed inside the loading tray 3, and the fan 7 and the electric heating wire 6 are subsequently started. When the fan 7 is running, the external air is sucked into the mounting frame 5, and the impurities in the air are filtered through the filter 8. The air passes through the electric heating wire 6 to heat the air flow, and the heated air is provided to the air supply pipe 4 and transported to the air outlet pipe 17, and then transported to the foam glass on the loading tray 3 to dry the foam glass. In order to avoid the problem of inaccurate experimental data caused by uneven heating of the foam glass, the servo motor 10 is started to drive the turntable 11 and The thin rod 12 rotates synchronously, and then under the limit of the hollow frame 13, the circular motion of the thin rod 12 is converted into the reciprocating linear motion of the hollow frame 13.

When the I-frame 22 is pushed, it slides and compresses the spring 21 inside the fixed frame 19, so that the spring 21 generates an elastic force. When the I-frame 22 slides, it drives the U-shaped frame to move downward, and the U-shaped frame moves downward, driving the brush 24 to move downward. The brush 24 and the filter screen 8 abut against each other to clean the dust attached to the filter screen 8. When the cam 20 does not push the I-frame 22, the spring 21 pushes the I-frame 22 to reset, the I-frame 22 drives the U-shaped frame, and the U-shaped frame drives the brush 24 to reset. During the reset of the brush 24, the filter screen 8 is cleaned again.
[0032] Preferably, one end of the spring 21 is fixedly connected to the inner bottom wall of the fixed frame 19, and the other end of the spring 21 is fixedly connected to the bottom wall of the I-frame 22.
