Abstract

A fluidized drying bed comprises a fan heating device which comprises a fan, a first heater and a control circuit. The control circuit comprises a control end, an input end and an output end, the control end of the control circuit is connected with the fan, the input end of the control circuit is connected with a controller power source, and the output end of the control circuit is connected with the first heater; when the fan normally works, the control end of the control circuit is connected, and the first heater is connected to the controller power source and works; when the fan stops running, the control end of the control circuit is disconnected, and the first heater is disconnected with the controller power source and stops working. The fan and the heater are integrally controlled by the control circuit, namely when the fan trips due to faults or stops working due to other reasons, the control circuit controls the heater to stop, and fires and other accidents caused by too high heating temperature are avoided.

Description

technical field [0001] The invention relates to a fluidized drying bed. Background technique [0002] Fluidized bed, also known as fluidized bed. Since it has been used for more than 40 years, it has been continuously improved and improved, and it is widely used in pharmaceutical, chemical, food, grain processing and other industries, such as raw material medicine, granule finished medicine, granule, feed, plastic resin and other powdery and granular forms. Dehumidification and drying of materials. [0003] Existing dryers generally include a dryer host, a heater and a fan for drying wet materials. The main body of the dryer is provided with an air inlet and an air outlet. After the hot air from the heater enters the main body of the dryer, the wet material in the main body of the dryer is boiled by the hot air. Due to the extensive contact between the hot air and the material, the drying can be completed in a short time. [0004] In the existing dryer, when the fan brea...
