Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

Example 1

A powder drying device comprises a shell 1, a blower 3, a heater 4 and a base 7, wherein the shell 1 is cylindrical, the surface of the shell 1 is respectively provided with an air inlet 101, an air outlet 102, a feed inlet 103 and a discharge outlet 104, the feed inlet 103 is positioned at one end of the top of the shell 1 close to the air outlet 102, the discharge outlet 104 is positioned at one end of the bottom of the shell 1 close to the air inlet 101, hot air entering from the air inlet 101 is firstly contacted with powder with the lowest water content, wet material entering from the feed inlet 103 is firstly contacted with hot air with the highest humidity and the lowest temperature so as to fully utilize the heat of the hot air and reduce the water content of the powder at the discharge outlet 104 as much as possible, the blower 3 and the heater 4 are connected in series, the blower 3 sends outside air into the heater 4, the heated air enters the shell 1 from the air inlet 101, the heater 4 uses an air duct type air heater, the outlet of the heater 4 is communicated with the air inlet 101, the shell 1 is fixedly installed on a base 7, the drum 2 and the motor 5 are further included, the drum 2 is arranged in the shell 1 along the horizontal direction, a first bearing 8 and a second bearing 9 are respectively arranged at two ends of the drum 2, the first bearing 8 and the second bearing 9 are thrust bearings, the drum 2 is rotatably connected with the shell 1 through the first bearing 8 and the second bearing 9, blades 201 are arranged on the portion, located inside the shell 1, of the drum 2, the blades 201 are spiral plates, partition plates 203 are further arranged on the surface of the drum 2, the axis of the drum 2 is located in the plane where the partition plates 203 are located, the blades 201 are divided into a plurality of lattices through the partition plates 203, through holes 204 are formed in the blades 201, the through holes 204 are located between the two adjacent partition plates, one end, close to an exhaust port 102, of the drum 2 extends out of the shell 1 and is fixedly connected with a driven wheel 202, the driven wheel 202 is connected with the rotating shaft of the motor 5 through belt power, so that the motor 5 can drive the drum 2 to rotate, the exhaust dust collector further comprises a cyclone separator 6, wherein an inlet of the cyclone separator 6 is communicated with the exhaust port 102 and used for collecting dust in the tail gas and preventing environmental pollution.
