Description

Flash dryer with slag discharging and returning mechanism Technical Field The utility model belongs to the technical field of flash drying machines, and particularly relates to a flash drying machine with a slag discharging and returning mechanism. Background The flash dryer is high-efficiency drying equipment, has the advantages of high drying speed, short residence time, good product quality and the like, and is widely applied to the industries of chemical industry, pharmacy, food and the like. For example, chinese patent publication No. CN213273569U discloses a flash dryer, which comprises a flash dryer, a rotating shaft and a support, wherein the rotating shaft comprises a main shaft, the main shaft is sequentially provided with a belt pulley, a lower gland, a lower bearing, an upper gland, a blade and a fixing nut from bottom to top, a bearing chamber is arranged between the upper bearing and the lower bearing outside the main shaft, and a spiral sheet is arranged on the rotating shaft inside the bearing chamber. The spiral piece is arranged on the rotating shaft in the bearing chamber, when the rotating shaft rotates, the spiral piece rotates along with the rotating shaft, lubricating oil in the rotating shaft is driven to move upwards by the spiral piece, the lubricating oil plays a sealing role at the moment, a gap between the bearing chamber and the rotating shaft is sealed, materials can be effectively prevented from entering the bearing, the influence of the materials on the bearing is avoided, the service life of the device is prolonged, the long-period stable operation of the device is ensured, and the occurrence of safety accidents is avoided. The above patent has the following problems: The patent has some defects in use, such as that after the device works, materials are directly discharged, part of large-particle materials are wrapped and clamped by air flow and discharged together with the air in the discharging process, and the materials which are not sufficiently dried or reach the particle size standard can be mixed into qualified products, so that the quality of the products does not reach the standard in the subsequent use, and the production benefit and brand public praise are affected. In view of this, we propose a flash dryer with a slag-off and return mechanism.
