Embodiment 1
[0059] The hot-melt material purification method of the present embodiment comprises the following steps:
[0060] The first step: the hot-melt material to be purified is introduced into the uniform temperature box 3 through the stock pump 5, and the temperature T1 is adjusted at the same time, and the T1 is 80-140 degrees Celsius;
[0061] Step 2: Preheat the rotary barrel 19 to a temperature T2, and T2 is 80-120 degrees Celsius;
[0062] Step 3: The hot-melt material with a temperature of T1 is pumped into the cavity of the rotary drum 19 of the centrifugal device that has been preheated to the temperature T2 and operated according to the separation factor A through the feed pump 6 at a constant flow rate L, and the material in the rotary drum 19 is Impurities with different specific gravity such as moisture, ash, oxides and carbides in the hot-melt state materials are radially and accurately stratified; the flow rate L is 0.2-0.8 cubic meters per hour, and the separation fa...
