Problems solved by technology

[0005] Generally, water is used as the heat exchange medium in heat exchange pipes. Since the temperature of the water from the inlet end to the outlet end of the heat exchange pipes is not the same, the heat exchange efficiency is different and the heat exchange is uneven. At the same time, the outer surface of the heat exchange pipes will also condense the material This leads to a decrease in heat transfer capacity and intensifies the crystallization of the material on the outer wall of the main shaft 1, which will affect the medium channel
[0006] In addition, because the water has been used for a long time, it is easy to scale. Once the scale accumulates, the heat exchange capacity will decrease. It is necessary to stop the granulator for descaling maintenance, which greatly affects the output of the granulator.

Embodiment 1

[0025] In the heat exchanger of Embodiment 1, a heat exchange medium 16 and a heating device 12 that rotates synchronously with the main shaft 1 are arranged inside the main shaft 1. The heating device 12 continuously heats the heat exchange medium 16 for constant temperature control, so that the temperature of the heat exchange medium 16 is uniform, and then Solved the problem of uneven heat transfer.

[0026] Preferably, the heat exchange medium 16 is heat transfer oil. This prevents scaling and requires no additional maintenance.

[0027] The main shaft 1 is generally driven by a motor and a reducer. In order to enable the main shaft 1 and the heating device 12 to rotate synchronously, preferably, the inner wall of the main shaft 1 is connected with a sleeve bracket 6, and the outer side of the heating device 12 is sleeved with a connecting sleeve 7. The pipe support 6 is connected with the connecting sleeve 7 . As a feasible implementation known to those skilled in the a...

Abstract

The invention provides a heat exchanger which comprises a first casing, a main shaft and a heating device, wherein the first casing is provided with a first accommodating cavity for accommodating materials; the main shaft penetrates through the first accommodating cavity rotationally and is provided with a second accommodating cavity, and a heat exchanger medium is arranged in the second accommodating cavity; and the heating device penetrates through the second accommodating cavity and rotates synchronously with the main shaft, and a first end of the heating device penetrates out of the main shaft and is connected with a power supply. The heat exchanger effectively solves the problem of uniform heat exchange, and the structure is simple.

Description

technical field [0001] The invention relates to a heat exchanger. Background technique [0002] A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid. It is a general-purpose device in chemical, petroleum, power, food and many other industrial sectors, and plays an important role in production. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators, etc., and are widely used. Heat exchangers have different uses, various types, and different performances. [0003] The working principle of the heat exchanger is to transfer part of the heat of the hot fluid to the cold fluid. For example, the shell-and-tube heat exchanger is a typical heat exchange structure. The heat medium flows through the pipe. Because of the temperature difference between the heat medium in the pipe and the cold fluid in the shell, heat exchange will be formed. The heat of the high-temperature object is always transferred to ...
