Stirring heat transfer device

Abstract

An inclined disc dryer comprises a casing inside which four hollow shafts with a substantially cylindrical contour and with identical diameter and length are arranged in parallel to and spaced from each other to allow for free rotation, namely parallel arranged in a horizontal direction. Opposite ends of the hollow shaft are mounted on the casing that is hermetic and are rotatably supported by bearings. A front end of the hollow shaft is coupled to a rotation drive means comprised of a gear mechanism and a motor. Discharge ports of suitable number are formed in a lower part or side parts of the casing, a water jacket or a gate plate at locations adjacent a rear end of the hollow shaft. Adjacent the discharge ports, a number of, namely two to three, pieces of hollow stirring plates are mounted to the hollow shaft in a substantially vertical direction with respect to the axis of the hollow shaft, rather than in an inclined manner. The device prevents the substance that is processed or dried material from pressing a bottom of the rear end side thereby eliminating wearing of the bottom of the casing.

Description

technical field [0001] The invention relates to a plurality of rotatable hollow shafts arranged in parallel in a casing, and a plurality of hollow stirring plates are obliquely arranged in each hollow shaft, and then through the A hollow stirring plate and a rake blade larger than the hollow stirring plate are arranged in a substantially vertical direction in the hollow shaft portion of the width, so that heat exchange treatment can be performed while stirring the material to be treated supplied into the housing. Stirring device for smooth discharge. Background technique [0002] In the past, as this kind of agitation heat transfer device, for example, a plurality of rotating shafts are spaced in parallel in a substantially horizontal housing with a water jacket structure on the outer periphery, and stirring plates are provided on the rotating shafts. The rotating shaft and the stirring plate are hollow, and a heat exchange medium is passed through the inside of the rotatin...

AI Technical Summary

Problems solved by technology

According to the prior art, the material to be processed supplied from the feed inlet of the stirring heat transfer device is transferred into the device while being heated or cooled while stirring, and then the processed finished product or dry product is taken out from the discharge port. All the stirring plates are formed by inclination relative to the plane that is at right angles to the axial axis of the rotating shaft, so the finished product or dried product will strongly press the bottom of the housing of the stirring heat transfer device, and the processed dried product At the same time, it is difficult to discharge from the discharge port. At the same time, by repeatedly performing the strong pressing action of the dried product, etc., it will cause the bottom of the shell to wear and cause damage such as cracks or openings, and also induce heat exchange into the shell. Leakage of media such as steam, warm or cold water
