Stirring heat transfer device

Abstract

The invention relates to a stirring heat transfer device, which prevents the abrasion of a bottom part of a casing by preventing treated matter or a dried product from being pressed to the bottom part at the other end (rear end) of the casing. Four approximately cylindrical hollow shafts are arranged in parallel in the casing rotatably along the longitudinal direction of the casing. Both ends of the hollow shafts are respectively projected from one end face 1a and the other end face of the casing in a sealed condition, and rotatably supported by bearing parts. The desired number of discharge ports are formed on the casing, or a part near a lower part and a side part of a jacket or a case body at the other end (rear end) of the hollow shafts, and a plurality of hollow stirring plates are mounted approximately vertically to a longitudinal axis of the hollow shafts without being inclined, on the hollow shafts near the discharge ports.

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
