Background technology
Sand mill is one of equipment necessary in coating production process, and it,, by its inner abrasive media and the collision between colored paint, is separated into original particle by colored paint, can, evenly in paint vehicle, form required mill base.Sand mill in conventional solution, it is due to the friction between abrasive media and mill base in process, and part mill base is unavoidably left on abrasive media surface.Residual mill base not only can cause the loss of raw material, can make sand mill in following process process simultaneously, and the mill base of remained on surface is mixed with follow-up mill base, thereby causes the purity of mill base to decline.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of sand mill, and it can effectively remove the mill base that remains in abrasive media surface in process each time.
For solving the problems of the technologies described above, the present invention relates to a kind of sand mill that keeps mill base processing purity, it comprises cylindrical shell, and is arranged on feeding mouth and discharging opening on cylindrical shell; Described inner barrel is provided with dispersion axle, disperses to be evenly provided with a plurality of dispersion impellers on axle; In described cylindrical shell, discharging opening inside is provided with screen cloth.In the described sand mill that keeps mill base processing purity, the position of discharging opening is provided with abrasive media process chamber; Described abrasive media process chamber is arranged at the below of discharging opening, and with discharging opening between by magnetic valve, be connected; In described abrasive media process chamber, be provided with supersonic generator, ultrasonic transducer, and pipe blow-through, described pipe blow-through is connected to the cleaning liquid bath that is arranged on cylindrical shell outside; In described abrasive media process chamber, be provided with and extend to its outside drainage pipeline, and the feed back pipeline that is connected to inner barrel; Described drainage pipeline, and the position that crosses of feed back pipeline and abrasive media process chamber is provided with magnetic valve.
As a modification of the present invention, in described abrasive media process chamber, be provided with the shaft vertically extending, it is connected to the motor that is arranged on abrasive media process chamber outside; On described shaft, be provided with a plurality of stirring vanes from the horizontal by certain angle.Adopt above-mentioned design, it can drive shaft to drive stirring vane to rotate by motor, thereby make abrasive media under the drive of stirring vane, in abrasive media process chamber, be rotated and then be uniformly dispersed, avoid abrasive media to be deposited in a place and cannot thoroughly to it, carry out supersonic cleaning.
As a modification of the present invention, the distance between described shaft upper end and abrasive media process chamber upper surface is at most 5 centimetres, is provided with at least 3 group stirring vanes in shaft, and it is uniformly distributed on stirring axis direction; Every group of stirring vane is by two axis in same plane, and stirring vane positioned opposite to each other forms; Described stirring vane is 40 to 50 ° from the horizontal by acutangulate scope.Adopt above-mentioned design, it can make the contact-making surface between stirring vane and abrasive media increase, thereby stirring vane is improved to the mixing effect of abrasive media.
As a modification of the present invention, described drainage pipeline, and feed back pipeline is all arranged on the lower surface of abrasive media process chamber; In described drainage pipeline, be provided with filter course, drainage pipeline is connected to clean liquid bath.Adopt above-mentioned design, it can be convenient to abrasive media and cleaning fluid is discharged abrasive media process chamber.
As a modification of the present invention, the axis of described feed back pipeline is in vertical direction with certain angle, the scope of itself and the alleged acute angle of vertical direction is 30 to 40 °, and it can make abrasive media along feed back pipeline natural downslide to inner barrel, thereby avoids it residual to some extent.
As a modification of the present invention, in described drainage pipeline, filter course consists of the first filter course and the second filter course, and described the first filter course is arranged between magnetic valve and abrasive media process chamber, and described the second filter course is arranged on drainage pipeline end position; Between described the second filter course and magnetic valve, be provided with openable cover plate.Adopt above-mentioned design, described the first filter course can be stayed abrasive media in abrasive media process chamber, thereby avoids it with cleaning solution, together to discharge; The second filter course can be by cleaning solution, and the mill base residue from abrasive media surface clean stays, and is taken out by cover plate, thereby realizes the recovery of material.
The above-mentioned sand mill that keeps mill base processing purity, mill base and abrasive media enter after inner barrel from feeding mouth, disperse axle under motor drives, to drive dispersion impeller rotation, thereby the mill base of making and abrasive media rise gradually.In uphill process, mill base and abrasive media keep turbulent motion between cylindrical shell, dispersion axle and dispersion impeller, and mill base and abrasive media rub and collision all the time simultaneously, thereby complete the dispersion to mill base by abrasive media.After sand mill disperses mill base, sand milling medium and mill base are together delivered in discharging opening.In discharging opening, sand milling medium is residual under the filtration of screen cloth, and enters abrasive media inner treatment chamber.In abrasive media process chamber, supersonic generator and ultrasonic transducer clean abrasive media by ultrasonic wave, thereby make the mill base of abrasive media remained on surface separated with abrasive media, are suspended in cleaning solution.After cleaning completes, abrasive media conveying meeting inner barrel carries out spreading the work next time, carries the cleaning solution of mill base and after filtering, returns clean liquid bath, can be for follow-up after lower mill base collection and filter.
Adopt the sand mill of the kept mill base processing purity of technique scheme, its mill base that can effectively clean abrasive media work in-process remained on surface washes away, thereby avoid abrasive media in following process, its surperficial mill base is mixed with new mill base, cause coating finished product purity to decline to some extent; Meanwhile, it can be collected the mill base residue that remains in abrasive media surface, and recycles, thereby reduces the loss in production process.
