Description

The existing mud heating device is provided with a heat exchanger, and a plurality of vertically arranged heat exchange tubes are arranged in the heat exchanger. Mud is passed into the heat exchange tubes, and each heat exchange tube is arranged at intervals. The heat at the tail of the kiln is transferred to the water, that is, the water is heated. The heated water is passed into the heat exchanger, contacts the heat exchange tubes, and transfers the heat of the water to the mud in the heat exchange tubes, thereby achieving mud heating. However, the gaps between the multiple heat exchange tubes are very small, and it is easy to scale at the gaps after long-term use, reducing the contact area between the hot water and the heat exchange tubes and reducing the heat exchange efficiency. In addition, the diameter of the mud tube is small, and it is easy to be blocked, resulting in unstable production. Finally, its water inlet and return water inlet are both located in the middle of the heat exchanger, and it is difficult for hot water to be evenly distributed throughout the heat exchanger. The hot water cannot be guaranteed to contact all the heat exchange tubes, which also makes the heat exchange efficiency low. Utility Model Content
