Abstract

The invention discloses a circulating hot air drying furnace, which comprises a drying furnace shell and a rotating main shaft. A motor is installed at the center of the bottom end of the drying furnace shell, and the output rotating shaft of the motor is connected with the rotating main shaft through a coupling. One end of the rotating main shaft is equipped with an impurity collection cylinder, one end of the fixed shaft is equipped with a slider, and the inside of the drying furnace shell is equipped with a disc track, and the disc track is connected with four sliders , the top of the drying furnace shell is equipped with a hot air blower, one end of the hot air blower is connected with a hot air pipe, the hot air pipe is connected with the drying furnace shell, and the gas filter and the circulating fan are connected with a A gas pipeline, a furnace door is arranged on the surface of the drying furnace shell. In the present invention, due to the action of centrifugal force, the porous cylinder can throw the impurities in the raw materials into the impurity collection cylinder to realize the removal of impurities from the raw materials, and at the same time speed up the contact surface between the raw materials and the hot air, so as to speed up the drying efficiency of the materials.

Description

technical field [0001] The invention relates to the technical field of hot air drying, in particular to a circulating hot air drying furnace. Background technique [0002] Hot air drying, also known as "instant drying", is to make the heating medium (air, inert gas, gas waste gas or other hot gas) directly contact with the solid particles to be dried, and to suspend the solid particles to be dried in the fluid, so the contact area of ​​the two phases It is large, strengthens the heat and mass transfer process, and is widely used in the drying unit operation of bulk materials. The hot air drying often uses a drying furnace, but the traditional circulating hot air drying furnace has a single function and does not have the function of filtering and removing impurities from raw materials. Contents of the invention [0003] The purpose of the present invention is to provide a circulating hot air drying furnace to solve the problem that the circulating hot air drying furnace in...
