Four-channel rotating jacket

Abstract

The invention relates to a four-channel rotating jacket, belonging to the technical field of heat exchange. Heat-exchange fluid medium enters a flow passage in the jacket through a water inlet (3) of the jacket of a four-channel water-dividing ring (4) from a hollow rotating shaft (18), a horizontal channel partition plate (6) divides a biconical jacket (19) with symmetrical geometric dimension into two symmetrical regions, a longitudinal return water partition plate (5), a longitudinal guide partition plate (7) and a longitudinal channel partition plate (15) divide each region into two symmetrical channels, a horizontal flow passage partition plate (9) and a longitudinal return water partition plate (5) are provided with flow passage ports (1) and (14), respectively, each flow passage forms flowing through the flow passage port, the heat-exchange fluid medium enters the four-channel water-dividing ring (4) through a water return port (2) of the jacket, returns to the hollow rotating shaft (18) and flows out. According to the invention, the heat-exchange fluid medium enters the four-channel rotating jacket through the four-channel water-dividing ring, so that the situation that the medium flows through all heat exchange regions of the jacket is ensured, and four channels have consistent geometric dimensions, flow rates and inner temperature fields.

Description

technical field [0001] The invention relates to the improvement of the jacket function of a rotary jacketed container equipment, and belongs to the technical field of heat exchange. Background technique [0002] Rotary jacketed heating or cooling container equipment, the fluid medium in the jacket must enter and exit through the hollow rotating shaft that drives the rotation. The fluid in the rotating jacket cannot flow according to the ideal working conditions, the flow rate is extremely low, and it is easy to short circuit. The temperature field distribution in the heat exchange area of ​​the inner wall of the container is not uniform, and the heat exchange efficiency is low when the temperature of the fluid medium in the jacket is given. Contents of the invention [0003] The object of the present invention is to provide a four-channel rotary jacket, which is suitable for a rotary jacketed container with symmetrical geometric dimensions, and can enter the heat exchange...
