Embodiment Construction
[0023] The present invention is described in detail below in conjunction with accompanying drawing:
[0024] Such as figure 1 Shown, a kind of alkali-adding and diluting device that prevents Kjeldahl azotometer sample from bumping comprises a digestion tube 1, and a retort 3 communicated with the interior of the retort is installed at the top opening of the digestion tube 1, and the retort After a condenser 4 is connected in series at the top, it is connected with a titration cylinder 6. Meanwhile, the distilling bottle is also provided with lye and water inlets, and the lye or water inlets are respectively connected with water pumps and alkali pumps. The water pump 7 and the alkali pump 8 are controlled by a control device 9 . A distillation head 2 is provided at the mouth of the connecting pipe between the distillation bottle 3 and the digestion pipe 1 .
[0025] The input end of the control device 9 is provided with a display, and a data input module is provided on the di...
