In order to ensure that the extracted humic acid chelated fertilizer is more standardized and efficient, equipment for producing the humic acid chelated fertilizer needs to be further improved, so that the equipment is more intelligent and more accurate, and manual operation is reduced, so that the aims of saving working time and improving production efficiency are fulfilled.

Through set up liquid level controlling means 4 on evaporation storehouse 1, control the liquid level height scope of humic acid chelate fertilizer liquid 100 in evaporation storehouse 1, it is specific, liquid level controlling means 4 is according to the liquid level height change of humic acid chelate fertilizer liquid 100, controls the flow that humic acid chelate fertilizer liquid 100 flows into evaporation storehouse 1, keeps steam cylinder 2 to sink into in the humic acid chelate fertilizer liquid 100 volume and is in the default.

This is because humic acid chelate fertilizer liquid 100 is refined under steam cylinder 2's high temperature, and the liquid level height can be constantly descend, consequently needs pump machine 3 can be intelligent to carry out the liquid feeding or stop the liquid feeding operation in evaporating storehouse 1, makes humic acid chelate fertilizer liquid 100's liquid level keep between the predetermined water flat line, makes steam cylinder 2 sink into in humic acid chelate fertilizer liquid 100 volume suitable, just so can guarantee the high-efficient production of humic acid chelate fertilizer.
