Stirring heat transfer device

Abstract

Disclosed is a stirring heat transfer device, wherein four hollow shafts capable of rotating neatly are set inside the housing with an equal interval, in the housing length direction and parallel to each other, and are also transversely deposited in the level direction. Both ends of said hollow shafts are connected respectively to one end surface of the housing and a protruding part placed sealing-like at the other end surface of the housing, and are supported rotatablely by bearing parts. One end (front) part of said hollow shaft is equipped with a gear mechanism and a motor meshing with each other and with the hollow shaft rotorating driving mechanism comprising the gear mechanism, the motor and the like. Appropriate amount of outlet orifices are set at the housing and a water jacket at the other end part (back) of the hollow shaft or at outer housing lower part and side part and the like, and a first sealing board and / or a second sealing board are set at one part of the hollow shaft at the inner wall within one end surface and / or the other end surface of the housing, wherein the sealing boards have their frontispieces inlining inwards and are set separated with each other. Said device is capable of ensuring that matters to be processes are prevented from leaking out when they are stirred, heat-transferred and fed to the housing and discharging finished products from the housing.

Description

technical field [0001] The present invention relates to a plurality of hollow shafts arranged in parallel and rotatable isolation in the casing, and a plurality of hollow stirring plates are obliquely arranged on each hollow shaft, and a sealing plate is arranged at the front end and / or rear end of the hollow shaft, And it is a technique to prevent the material to be treated supplied into the casing from leaking to the outside of the stirring heat transfer device. Background technique [0002] In the past, as this kind of agitating heat transfer device, for example, it is parallel and rotatably isolated to install a plurality of rotating shafts in a substantially horizontal housing with a water jacket structure on the outer periphery, and there are isolated stirring plates arranged on these shafts. And the rotating shaft and stirring plate are made hollow, and the heat exchange medium flows through the inside and the above-mentioned water jacket while stirring the powder or ...

AI Technical Summary

Problems solved by technology

[0006] According to the conventional technology, it heats or cools the object to be treated supplied from the inlet of the stirring heat transfer device while stirring it, and conveys it in the device, and takes out the processed product or dried product from the discharge outlet. , but at the front end and rear end of the above-mentioned hollow shaft, there will be various impurities and agglomerations such as non-solid and non-liquid mortar or ultrafine particles or dust generated in the housing residue, and leakage from the gap between the outer circumference of the hollow shaft and the housing through the shaft seal to the outside

[0007] In addition, in the prior art, the front end portion or rear end portion of the above-mentioned hollow shaft outside the front end or the rear end of the housing has a sealing member composed of a gland box, etc., but especially the front end portion of the housing It is very difficult to completely prevent the liquid fluid flowing out of the inner wall due to the temperature rise of the processed object with high water content, and it is very difficult to prevent it from flowing out to the outside of the casing.

[0008] In addition, in the prior art, since it does not have a sealing plate at the front end and / or rear end of the rotating shaft, it has the disadvantages of stirring, heat transfer, and transporting the processed object transferred to the rear end of the rotating shaft. When the inclination of a series of agitating plates disposed in the casing toward the axis of the hollow shaft is small or due to other types of objects to be processed, the object to be processed bounces back toward the front end of the rotating shaft or stays at the front end of the casing, and decreases Problems with stirring or conveying efficiency

[0009] And, there is also the object to be processed that is transported from the front of the casing to the rear, which is solidified and stagnated near the discharge port or the rear end inner wall or bottom of the casing, etc., and the object to be processed is pressed against the inner wall or the bottom of the casing. The inner wall or bottom of the shell will be worn away and cause damage such as cracks or perforations, which will cause problems such as leakage of the heat exchange medium flowing through the water jacket, such as steam or hot water and cold water, to the shell side.
