Open the liquid outlet 43 and the liquid inlet 6, and close the drain port 2; S3. Inject a certain amount of pulp into the liquid inlet 6.

By penetrating the heating pipe member through the heater housing and using the pressure difference between the inside and outside of the diversion pipe, the substances that are likely to deposit in the liquid are pushed into the liquid outlet device through the diversion pipe and discharged from the liquid outlet, highly ensuring that the pulp can be evenly heated during the heating process, thereby avoiding local overheating or unheated areas caused by pulp precipitation, and preventing phenomena such as scale formation inside the heating device and dry burning of the heating pipe, greatly prolonging the service life of the heating device and having a certain protective effect on the heating device.
