Description

Technical Field

[0001] This utility model relates to the technical field of electric thermostatic drying ovens, specifically an electric thermostatic drying oven with waste gas diversion function. Background Technology

[0002] An electric constant temperature drying oven is a drying device that uses electric heating elements to heat and maintain a constant temperature inside the oven. It mainly consists of a chamber, an electric heating system, a temperature control system, and a ventilation system. The chamber is generally made of high-quality materials and has good sealing and heat preservation properties, which can effectively reduce heat loss. The electric heating system converts electrical energy into heat energy through electric heating elements to provide heat for the drying process. The temperature control system can accurately sense the temperature inside the oven and automatically adjust the working state of the electric heating elements according to the set value to ensure that the temperature inside the oven is stable within the required range. The ventilation system can promote air circulation inside the oven, so that the heat is evenly distributed and moisture is expelled, thus accelerating the drying process. During the exhaust gas diversion process in the electric thermostatic drying oven, the exhaust gas drawn out of the oven is not pure; it contains various impurities. These impurities come from diverse sources, such as fine particles volatilized from materials during the drying process or dust accumulated inside the equipment due to long-term use. The presence of these impurities has a significant negative impact on the exhaust gas diversion process. They easily adhere to the inner wall of the diversion pipe and gradually accumulate over time, causing the inner diameter of the pipe to decrease, thus hindering the smooth flow of exhaust gas and greatly reducing the diversion efficiency.

[0003] Therefore, an electric thermostatic drying oven with waste gas diversion function is proposed. Utility Model Content

The treatment chamber 34 is fixedly fitted inside the connecting ring 33, and the right end of the treatment chamber 34 is located inside the positioning frame 32 to ensure that the exhaust gas can smoothly enter the treatment chamber 34. After the exhaust gas enters the treatment chamber 34, it will pass through two filters 37 set inside the treatment chamber 34.

The exhaust gas filtered by the filters 37 is discharged from the exhaust pipe 36. Furthermore, in this embodiment, the exhaust gas in the constant temperature drying chamber 1 is drawn out by the exhaust fan 31, and the exhaust gas is filtered by the filter screen 37 in the treatment chamber 34 to remove impurities and particulate matter in the exhaust gas, thereby reducing the pollution of the exhaust gas to the environment. Two filters 37 are set on the left and right sides to improve the purification effect of the exhaust gas.
