Description

TECHNICAL FIELD

[0001] The application relates to the technical field of chemical experiment equipment, in particular to a protective cover for waterproof roll Soxhlet extractor experiment. BACKGROUND

[0002] As an important building material, the waterproof roll is often used for determining the soluble content in the waterproof roll by Soxhlet extraction method in the quality detection process, so as to evaluate the material performance. However, when the Soxhlet extractor is used for the experiment on the waterproof roll in the laboratory, the safety and reliability become an important problem that cannot be ignored.

[0003] In order to ensure the smooth progress of the experiment, some simple physical protection measures are usually adopted to reduce the experimental risk. The existing protection measures mainly include installing an air exchanger fan in the experimental operation room or using an experimental container made of heat-resistant material, which can reduce the possible dangers in the experimental process to a certain extent, but still cannot make the high-temperature and high-pressure gas quickly exhaust.

[0004] In the process of using the Soxhlet extractor to carry out the heating extraction experiment, a large amount of high-temperature gas is generated in the heating process, and the gas pressure is continuously generated by the gathering. The existing simple protection measures cannot effectively collect and process these gases, so that there are explosion or other safety hazards in the experimental process. CONTENT OF THE INVENTION

[0019] An air exhaust pipe is arranged on the side wall of the cover body, and the air exhaust pipe is in communication with the air exhaust;

Compared with fixation on the wall surface only by relying on one side wall, the multi-point fixation mode can more evenly disperse the force borne by the cover body, improve the stability of the cover body in each direction, and make the cover body not easily shake or tilt even when affected by external force impact or motor vibration.

[0028] Optionally, the cover body is made of high-temperature-resistant material.
