Rotary drum and drying machine comprising same

Abstract

The invention discloses a rotary drum. The rotary drum comprises a rotary drum body and a rotational flow plate; the rotational flow plate is located on the inner surface of the rotary drum body and is connected with the rotary drum body; a screen is arranged inside the rotary drum body; the screen and a feeding port of the rotary drum body are located at the same end; and the rotary drum body is linked with the screen. The rotary drum is low in heat loss.

Description

technical field [0001] The invention relates to a rotary drum and a rotary drum dryer. Background technique [0002] Dryers can be divided into industrial and civilian. Industrial dryers are also called drying equipment or dryers. Civilian dryers are one of washing machines. They are generally used to remove clothing and other textiles after washing and dehydration. of moisture. [0003] The dryer has several modes such as belt drying, rotary drum drying, box drying, tower drying, etc.; heat sources include coal, electricity, gas, etc.; the drying process of materials has hot air flow type and radiation type. wait. [0004] At present, the rotary drum of the rotary drum dryer generally adopts a built-in mechanical dispersing device, and the rotating shaft traverses the entire rotary drum along the axial direction of the rotary drum. Radial breaking teeth are installed along the radial direction of the rotating shaft. The two ends of the shaft are fixed and installed by b...

AI Technical Summary

Problems solved by technology

In order to avoid damage to the shaft end bearing due to high temperature, a hollow shaft is usually selected for the rotating shaft, and circulating cooling water is introduced into the cavity of the rotating shaft to reduce the temperature of the rotating shaft and prolong the service life of the bearing. However, due to the cooling water, it will take away The heat in the rotary drum has a large loss of heat energy
