Description

Technical Field

[0001] The utility model belongs to the technical field of straight-through pipe dredging, in particular to a device for dredging the straight-through pipe of an adiabatic accelerating calorimeter. Background Technique

[0002] An adiabatic accelerating calorimeter is a new type of thermal analysis instrument for hazardous material assessment. During chemical reactions and process scale-up, by testing and analyzing data such as time-temperature-pressure of chemical reactions under adiabatic conditions, the safety conditions of the process can be evaluated and hazards caused by runaway reactions can be avoided. Through testing, the start and severity of runaway reactions can be detected, and the key links in the reaction process can be identified, thus providing reliable data for safety assessment and the design of new process schemes. During the experiment, a variety of chemical samples will be tested. The temperature of the adiabatic test usually ranges from room temperature to 500 °C. At this time, most organic substances will decompose, generating volatile components. When the adiabatic experiment ends, some of the volatile components will condense in the straight-through pipe to produce solid substances. These substances are usually relatively hard and difficult to clean, resulting in the blockage of the entire gas pipeline, which will affect the subsequent testing of the adiabatic accelerating calorimeter.

[0003] A medical device pipeline dredging device with the publication number CN219802451U, by placing the device body into the medical device pipeline, the image acquisition element set on the device body acquires the image information inside the pipeline. The operator observes the structure and blockage situation inside the pipeline through an external display device connected to the image acquisition element. At the same time, the grabbing part on the device body is driven by the driving part to grab the blockage inside the pipeline, thus completing the visual dredging operation. However, it is not suitable for the dredging of straight-through pipes. In order to better carry out the experiment, a dredging device has been designed at present, which can quickly dredge the straight-through pipe, keep the gas path unobstructed, and ensure the subsequent use of the adiabatic accelerating calorimeter.

[0040] Working principle

[0041] When this device for dredging the straight pipe of the adiabatic acceleration calorimeter is needed, start the heating wire 6 to heat the heating plate 4. Through the heat conduction of the heat conductor 7, the probe 3 is further heated;

[0042] After heating, press the airbag ball 34 to deliver the gas inside the airbag ball 34 into the inside of the lifting cavity 11. Thus, the air plug plate 31 can be pushed to move, causing the probe 3 to move. When the airbag ball 34 is released, the airbag ball 34 automatically resumes. The one-way valve body 35 at the end of the airbag ball 34 allows external gas to enter the inside of the airbag ball 34. Repeating this process can move the air plug plate 31 and push the probe 3 to move;

[0043] When the pushing is blocked, start the drive motor 24 to drive the drive rod 25 to rotate, causing the driving gear 23 to rotate, making the transmission gear ring 22 and the transmission gear 21 rotate, and further causing the probe 3 to rotate, thereby drilling through the blocking part.
