The invention discloses an automatic
emulsion preparation apparatus. The automatic
emulsion preparation apparatus comprises a water purification apparatus, an
emulsion preparation apparatus and a controller; the water purification apparatus comprises a
flocculation pretreatment apparatus, a filtering apparatus, a
water softening apparatus, a pH adjusting apparatus and a
water storage apparatus; the emulsion preparation apparatus comprises a liquid mixing box, a mixer, a concentration sensor, a second electric valve, a
water flow gauge, a
high pressure pump, a
gear oil pump, a frequency converter and a controller; and the controller is connected with a stirring mechanism, a pH sensor, a first electric valve, a
circulating pump, a concentration sensor, the second electric valve, the
water flow gauge and the frequency converter of the
gear oil pump. By adopting the automatic emulsion preparation apparatus, the automatic proportioning of
emulsified oil and
clean water is realized, the liquid supply quality of the emulsion is improved, the liquid mixing efficiency is increased, the abrasion and
corrosion of harmful substances on an underground hydraulic device can be prevented, the safety potential
hazard of a hydraulic support in use can be avoided, the use stability of the support is ensured, and an important actual significance on the safe and efficient production of a working face can be realized.
