The inner barrel is arranged in the outerbarrel, a feeding box communicating with the inner barrel is arranged at one end of the outer barrel, a feeding baffle is arranged at the end, close to the feeding box, of the inner barrel, a discharging guide plate is arranged at the end, far away from the feeding box, of the inner barrel, a ventilation opening and a discharging opening are arranged at the other end of the outer barrel, a front support frame and a rear support frame are arranged at the lower end of the outer barrel, the motor is fixed on the front support frame, the main shaft is connected to the middle of the inner barrel, one end of the main shaft is arranged outside the outer barrel and connected with the motor through a chain, a sealing plate is arranged between the rear support frame and the outer barrel, the supporting barrel device is arranged at the upper end of the rear support frame, a supporting hole matched with the supporting barrel device is formed in the side wall of the outer barrel, a smooth ring matched with the supporting barrel device is formed in the outer wall of the inner barrel, the two ends of the smooth ring are provided with fire retardant plates connected with the inner wall of the outer barrel, and the side wall of the outer barrel is provided with a furnace opening.

Description

technical field [0001] The invention relates to the technical field of dryers, in particular to an energy-saving drum dryer. Background technique [0002] Drum dryer is one of the traditional drying equipment, which is reliable in operation, flexible in operation, strong in adaptability, and large in processing capacity. It is widely used in metallurgy, building materials, chemical industry, coal washing, chemical fertilizer, ore, sand, clay, kaolin, sugar, etc. field. [0003] The traditional dryer is a cylinder that is slightly inclined to the horizontal direction. The material is fed from the higher end, and the high-temperature hot flue gas and the material flow into the cylinder together. With the rotation of the cylinder, the material moves due to gravity. To the lower end, the dried product is collected from the lower part of the bottom end. The traditional dryer has a single wall, poor sealing, and the short hot air flow leads to serious heat loss. In order to impr...
