Description

Technical Field

[0001] The utility model relates to a thermal cleaning furnace with good paint stripping effect, belonging to the technical field of thermal cleaning furnaces. Background Art

[0002] The thermal cleaning furnace has two relatively independent heating systems and temperature and smoke control systems. In the first heating system, the furnace cavity is heated to a certain temperature range, and the temperature in the furnace is automatically controlled by the control system, so that the coating on the workpiece is gradually decomposed into gas. The control system always ensures that the decomposition speed and the concentration of the decomposition products are strictly controlled within a certain range. When the decomposition products are treated by high temperature in the second heating system, they are converted into CO2 and water vapor and discharged through the chimney. What remains in the furnace are the workpieces and unaffected inorganic substances. These inorganic substances have become powdery, and most of them have fallen on the bottom plate of the furnace. The small amount of remaining can be shaken off by gently knocking and scrubbing with water.

[0003] When a traditional thermal cleaning furnace is burning a product, it can only burn one side of the product, resulting in incomplete combustion of the product. Incomplete combustion of the product is likely to cause incomplete combustion of the product, thereby affecting the paint stripping effect. For this reason, we have designed a thermal cleaning furnace with good paint stripping effect to solve the above technical problems. Utility Model Content
