Description

The shower nozzle of seed-coating machine spray gun
Technical field
The utility model relates to a kind of shower nozzle of seed-coating machine spray gun.
Background technology
The spray gun atomization sector effect of tradition seed-coating machine is normally realized by two small sircle holes on two row's small sircle holes and interstitial hole side on lance head inclined-plane, and circular hole broad in the middle is liquid.During spray gun work, first pass into compressed air, needle-valve in middle circular hole is opened, small sircle hole on lance head inclined-plane is also opened simultaneously, liquid is passed into again in spray gun, liquid starts atomization under the effect of interstitial hole side small sircle hole gas, adjusts atomization sector by two row's small sircle holes on lance head inclined-plane.The spray gun of this structure, the atomization mass of spraying can only reach a gasification result, and can produce very thick fluid column, can not scatter equably, makes the uniformity of atomization mass can not reach best, can not meet some particular/special requirement of pharmaceutical factory film coating procedure well.
Summary of the invention
Technical problem to be solved in the utility model is: the shower nozzle providing a kind of seed-coating machine spray gun of new structure, to overcome the above-mentioned defect that existing seed-coating machine spray gun operationally exists.
The technical scheme that the utility model adopts is: a kind of shower nozzle of seed-coating machine spray gun, the procephalic gas cap of described spray is provided with one-level gasification hole, secondary gasification hole and three grades of gasification holes, the wherein position of the adjacent nozzle liquid outlet in one-level gasification hole, secondary gasification hole and three grades of gasification holes are positioned at that one-level gasification hole is peripheral successively and with nozzle liquid outlet axially in a fixed inclination, described one-level gasification hole, secondary gasification hole are connected with the Compressed Gas interface on spray gun respectively by pipeline with three grades of gasification holes.For realizing best atomizing effect, the utility model preferred version is provided with four secondary gasification holes, four secondary gasification hole circle distribution at equal intervals; Be provided with gasification hole, two three grades gasification 8, two three grades, holes and be symmetrically distributed in nozzle liquid outlet both sides.
After spray gun use; usually in working order and when putting; nozzle needle and shower nozzle often damage by human factor; for protect needle-valve front end needle not easily people for fractureing or being out of shape; the further technical scheme of the utility model is: shower nozzle front portion is provided with shower nozzle flange; the needle that the height of shower nozzle flange is greater than needle-valve front end exposes the length of shower nozzle part, nozzle needle and shower nozzle on this flange energy available protecting spray gun.
From first order gasification hole high pressure draught out, make liquid material mouth produce negative pressure, the liquid material of sucking-off is carried out one-level gasification and is formed atomization mass.Very high straight line atomisation pressure and 360 degree of gasifications are had to produce uneven state because first order gasification fails to be convened for lack of a quorum, again by second level porous gasification stream, one-level atomized liquid is gasified again and reaches atomization evenly, produce pressure drag by the effect of secondary gasification inclined hole simultaneously, atomization mass is sprayed and can control within certain range of atomized flow.Gasified to flow by the third level again and change spray pattern, the fan flat spray pattern that final formation is best.
The beneficial effect that the utility model has: adopt technique scheme, can realize hydrojet and scatter equably, forms the atomizing effect that the uniformity is splendid; Shower nozzle flange can the needle of available protecting needle-valve front end and shower nozzle not by artificial damage.The utility model can meet the requirement of pharmaceutical factory film coating procedure well.
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described in further detail.
