A drum type rotary dryer

Abstract

The invention discloses a drum type rotary dryer. The drum type rotary dryer comprises a cylinder and a stirring structure, wherein the stirring structure is erected in the cylinder in the direction of the long axis of the cylinder, and can freely rotate, the cylinder and the stirring structure are supported by a feeding side machine frame, a discharging side machine frame and supporting rollers, opening portions arranged at the two sides of the cylinder are sealed by a feeding side cover and a discharging side cover respectively, a rotary shaft of the stirring structure is provided with a rotation fixing portion and a supporting portion used for perpendicular supporting, and a conveying direction carrying device and a scraping carrying device are arranged on the inner side of the cylinder. According to the drum type rotary dryer, adhesion of processed materials can be effectively reduced, dispersibility of the processed materials can be effectively improved, the phenomenon of blocking cannot happen inside the cylinder, adhesion of the interior of the cylinder is greatly reduced, the quantity of retained processed materials inside the cylinder is constant, the quantity of discharged processed materials is constant, the processed materials can be effectively crushed through the stirring structure, hot air can make contact with the processed materials more effectively, hot air efficiency is improved, and the processed materials with the uniform moisture content are obtained.

Description

technical field [0001] The invention belongs to the field of drying treatment equipment, in particular to a drum type rotary dryer. Background technique [0002] In recent years, more and more attention has been paid to environmental protection. Food drainage sludge from food factories, excrement and urine treatment in excrement and urine treatment plants, or sewage sludge in sewer treatment plants must be dried, volume-reduced, and treated to prevent corruption. be used as a renewable resource. Most of these muddy and cake-like treated substances have extremely high water content, strong adhesion, difficult to disperse, difficult to effectively contact with hot air, and very easy to adhere in the dryer, resulting in clogging of the dryer , The irregular peeling off of the processed product adhered inside the dryer will cause the moisture content of the processed product to be uneven, resulting in great errors, and the discharge of the processed product after drying is not ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a drum-type rotary dryer, aiming to solve the problem that the irregular peeling of the treated matter adhered inside the existing dryer causes the moisture content of the treated matter to be uneven, resulting in great errors. The amount of treated waste is not necessarily the same
