Specific embodiment
Aiming at the problem that powder mixing encounters in above-mentioned laboratory, the herein described mixing dress of applicant innovation and creation
It sets.
The utility model is described in further detail with reference to the accompanying drawing：
Refering to fig. 1 to Fig. 5, the utility model provides a kind of air blast powder mixing device, and described device includes 1 He of mixing tank
Air blower 2, the two are connected by sealing ventilation duct 3.Be provided with ventilation opening on the mixing pot sidewall, the ventilation opening on mixing tank with
Ventilation duct connection is sealed, the sealing ventilation duct other end is connect with air blower.The sealing ventilation duct can be divided into two sections, respectively
It seals among ventilation duct A18 and sealing ventilation duct B19, sealing ventilation duct A18 and sealing ventilation duct B19 through 4 connection of lock, it can
Disassembly, can clear up, and the junction that ventilation duct is sealed at two sections is equipped with O-ring seal.2 power adjustable of air blower, can basis
Demand changes wind-force size.Longitudinal ventilation opening 11 is provided on the mixing tank, the ventilation opening 11 is longitudinal flat-shaped structure.It is flat
The design of shape ventilation opening 11 enhances flow of the unit time by gas, and makes in different height powder by equivalent air-flow
Impact.The liner 6 and shell 5 are preferably hollow cylindrical body, the outer shell outer wall of the ventilation opening 11 and liner inner wall it
Between form vent passages 21, the vent passages 21 with cross the shell Chinese mugwort of ventilation opening 11 or the tangent line angle of liner less than 90 degree.
Because ventilation opening opening is not vertical with inner wall, inner wall, which serves as " slanting baffle " and can be formed to air-flow, stops to generate eddy airstream, meanwhile, it can
Effectively air-flow vertical impact inner wall is avoided to cause " to rebound " and make the abatement of wind.The mixing tank 1 includes shell 5, liner 6, sieve
