Technical Field

[0001] This utility model relates to the field of digester heating technology, and in particular to a digester heating device. Background Technology

[0002] The heating element of a digester is an important component of the digester, and its performance and characteristics directly affect the digestion effect and experimental efficiency. The heating principle of the digester heating element varies depending on the type of digester.

[0003] In practical applications, if a digester uses bottom heating, this method often results in uneven temperature distribution within the digester, leading to uneven heating of the sample. This uneven heating may cause incomplete digestion, with some areas being too hot while others are too cold, thus affecting the digestion effect and experimental accuracy.

[0004] Due to uneven heating, the digester may over-digest some samples while under-digesting others. This not only reduces the accuracy of the experiment but may also negatively impact subsequent analysis and testing results. Utility Model Content

This design ensures that heat is evenly distributed around the test tube, thus avoiding localized overheating or underheating and improving the accuracy and reliability of heating.

[0017] By precisely controlling the fan speed with a servo motor, the heating process can be finely adjusted. This adjustment capability allows the equipment to adjust the heating intensity according to actual needs, further improving the flexibility and adaptability of the heating process.

[0018] The auxiliary heating channel design not only helps to distribute heat evenly, but also effectively prevents heat loss and the entry of external impurities. This ensures the stability and cleanliness of the heating process, extending the service life of the equipment.

Set the desired heating temperature, time, and rotation speed on the touchscreen 2. Place the test tube 4 to be processed into the designated placement slot in the digester chassis 1. Click the start button on the touchscreen 2; the electric heating unit will then begin heating the bottom of the test tube 4. Start the fan 11, and control its speed via the servo motor 12 to ensure that hot air is evenly delivered into the auxiliary heating channel 5 for auxiliary heating of the side walls of the test tube 4. During the heating process, monitor the temperature and rotation speed in real time via the touchscreen 2 and adjust as needed. Once the set temperature and time are reached, the device will automatically stop heating and turn off the power. After the test tube 4 has cooled, remove it for further processing or analysis.
