When the pressure sensor 101 detects that the pressure in the vacuum tank 1 is less than P0The variable-frequency vacuum pump 4 reduces the vacuum-pumping rate and simultaneously reduces the opening degree of the regulating control valve 51, so that the pressure in the vacuum tank 1 is stabilized at P0. When the pressure sensor 101 detects that the pressure in the vacuum tank 1 is greater than P0The variable-frequency vacuum pump 4 increases the vacuum-pumping rate and at the same time increases the opening of the regulating control valve 51, so that the pressure in the vacuum tank 1 is stabilized at P0. The above adjusting mode ensures that the negative pressure in the vacuum tank 1 is stabilized at the working pressure P in the powder absorbing process0Therefore, the powder can be stably fed, the powder feeding amount can be accurately controlled, and meanwhile, the powder feeding efficiency and the dissolving efficiency of the powder in the solvent are effectively improved.
The utility model has the advantages that: the structure is simple and practical, and the effect is obvious. Secondly, the vacuum degree in the vacuum tank 1 is stabilized at the working pressure P by adjusting the vacuum pumping speed of the variable-frequency vacuum pump 4 and adjusting the opening degree of the adjusting control valve 51 on the vacuum adjusting pipeline 50Powder feeding volume just can be by accurate control like this to improve the precision of solution concentration greatly, and then improve product quality.
