[0002] A blast drying oven is a common experimental device, which is widely used in the fields of materials science, biomedicine, chemistry, etc. It controls the temperature and air circulation in the oven through a blast system and an electric heating system, so as to achieve the purpose of drying or heating samples. Dry hot rock experiments usually need to be carried out at a relatively high temperature to simulate the geothermal environment. The common temperature range of blast drying ovens is generally between room temperature and 300 °C, and high-end models can reach above 500 °C for adjusting the internal temperature change to simulate dry hot rock experiments.

[0003] When the existing dry hot rock simulation experimental device according to temperature change conducts a simulated temperature experiment on dry hot rock, high temperature will generate flue gas.

However, when the filter screen filters particulate impurities for a long time and too many impurities are adsorbed on it, it is easy to affect the filtration effect of the filter screen, and it is not convenient to automatically remove the impurities adsorbed on the filter screen, and manual cleaning is required. Frequent replacement and cleaning increase the labor intensity. Content of the Utility Model

[0029] Working principle: First, a dry hot rock simulation experiment device based on temperature change is used to heat rock samples to simulate different temperatures. Temperature simulation experiments are carried out on multiple groups of rock samples. When heating the rock samples, during the heating process, the moisture and volatile substances in the dry hot rock will be heated and released to form gas, thus resulting in the generation of flue gas. After the flue gas flows upward and enters the inside of the exhaust hole 7, it will flow through the filter screen 13. The filter screen 13 will filter and adsorb the particulate matter in the flue gas, thereby filtering and purifying the flue gas to avoid the influence of impurity dispersion on the surrounding environment. After long-term use, more impurities will be adsorbed at the bottom of the filter screen 13. If there are too many impurities, it will easily affect the filtering effect of the filter screen 13. When removing the impurities adsorbed at the bottom of the filter screen 13, the driving motor 14 is made to work, which will drive the threaded rod 15 to rotate. When the threaded rod 15 rotates, the threaded ring 16 will move. When the threaded ring 16 moves, it will drive the strip plate 17 to move. The strip plate 17 will drive the storage groove 21 to move. When the storage groove 21 moves, it will drive the scraper 22 to move. When the scraper 22 moves, it will scrape the impurities adsorbed at the bottom of the filter screen 13. The scraper 22 is inclined. After the scraped debris falls on the scraper 22, it will slide into the inside of the storage groove 21 for storage, achieving the purpose of automatically cleaning the filter screen 13, effectively avoiding too many impurities adsorbed on the filter screen 13 from affecting the filtering effect of the filter screen 13, without the need for manual frequent cleaning and replacement of the filter screen 13, reducing the labor intensity, and improving the practicability of the dry hot rock simulation experiment device based on temperature change. When carrying out simulation experiments on rock samples in the blast drying oven 1, there will be debris falling, and finally it will fall on the bottom plate 24. When removing the debris, the bottom plate 24 is pulled, and after the bottom plate 24 moves out of the inside of the sliding groove 23, the bottom plate 24 will move the debris to the outside, and then the debris can be removed, thereby achieving the purpose of facilitating the removal of debris inside the dry hot rock simulation experiment device based on temperature change and improving the cleaning efficiency.
