Description

Semiclosed loop powdery paints precipitation equipment

Technical field

The present invention relates to a kind of powder coating processing devices, more particularly to a kind of semiclosed loop powdery paints precipitation equipment.

Background technique

China is world manufacturing center, needs to consume a large amount of coating every year, and existing coating is mostly prepared liquid-type, Transport must barreled it is at high cost, unit dose than great, climate influence winter transport and storage be all easy to endure cold it is rotten, by these Factor restricts, and powdery paints was developed rapidly in recent years, and with packed at low cost, storage transport occupies little space, phase It is smaller than unit dose specific gravity, weatherproof is diluted without volume, avoids the loss endured cold, further decreases winter storage fortune Defeated cost still has some shortcomings with the needs that the yield of powdery paints is increased production, manufacturing equipment but not big technological progress Place, such as in terms of dust leakage, flour mill and feed bin are typically all closed cycle in production, and air-flow is sent into and is milled by air blower Machine drives powder to enter feed bin by flour mill outlet, and powder deposits in feed bin, and air-flow is extracted out by air blower again, forms enclosed and follows Ring is not completely closed since flour mill is equipped with sprue, dust is still had when positive pressure in flour mill and is leaked by sprue Out, it causes damages to production environment, not only influences staff's health, be also easy to cause dust storm catastrophic failure, this is asked Topic still up for solving, promotes the development of powdery paints industry.

Summary of the invention

To solve the above-mentioned problems, the present invention provides a kind of semiclosed loop powdery paints precipitation equipments.

The technical solution adopted by the present invention are as follows: a kind of semiclosed loop powdery paints precipitation equipment, it is characterised in that including deposition Storehouse, deposition storehouse are equipped with powdering inlet and air stream outlet, and powdering inlet cross section of fluid channel product is the 2 of air stream outlet cross section of fluid channel product Times, powdering inlet is connect by air blower with flour mill dust outlet, and air stream outlet is connect with flour mill air flow inlet；Deposit storehouse Storehouse plate on be provided with symmetrical window, two windows are greater than window or so width by the spacing of proximal edge, are connected on window The strainer being located on the outside of the plate of storehouse；Thereabout is equipped with fin on the inside of the plate of storehouse, and downside fin is lower than lower window edge, other three sides are convex Simultaneously, upside fin position perforation connection, downside fin between two windows pass through position between two windows for rib and window edge Lead to and connect, fin is equipped with gasket, is respectively equipped with sliding rail on the upside of downside fin downside and upside fin, is combined in sliding rail close Slide plate is sealed, sealing slide plate is bonded with gasket, is sealed slide plate and is covered the position between two windows and a window, between two windows Storehouse plate is equipped with the bar shaped gap of a left and right directions, and sealing slide plate is equipped with one by bar shaped gap through the handle on the outside of the plate of storehouse； The discharge port section for depositing storehouse lower part is rectangle, and the left and right ends of discharge port are respectively equipped with the expansion block engaged with discharge port, is discharged The front and rear sides of mouth are respectively equipped with elastic force intermediate plate, and discharge port is equipped with opening and closing flashboard.

Further, motor-driven eccentric shaking hammer is connected on the filter screen.

Further, the powdering inlet and air stream outlet are horn-like in deposition storehouse inner opening.

Air blower send the powder extraction in flour mill to deposition storehouse, due to powdering inlet cross section of fluid channel when the invention works Product than air stream outlet cross section of fluid channel product it is big, therefore deposit storehouse in be positive pressure always, fraction is flowed out by strainer, fraction by Air stream outlet is re-fed into flour mill and goes to blow afloat powder, and powdering inlet air flow rate is greater than air stream outlet air flow rate, in flour mill It is inside negative pressure always, supplement is entered by flour mill sprue by the tolerance that strainer flows out, such semiclosed cycle is not in Dust leakage, and strainer burden is small；Slide plate will be sealed by handle when use and slide to side, sealing slide plate and gasket paste It closes, seals the space between the side screen and two windows, air-flow can only be flowed out from another side screen, when dust accumulation to influence airflow When sealing slide plate slide into dust accumulation strainer side, seal the space between dust accumulation strainer and two windows, clean strainer work shakes at this time Dust accumulation strainer flows through dust accumulation strainer without air-flow at this time, and micronic dust will not be brought out by air-flow, dust accumulation fall into beneath window fin and The space between slide plate is sealed, dust accumulation strainer becomes clean strainer again and waits switch operating, can and so on guarantee the stream of air-flow It is dynamic, do not have to shut down i.e. changeable cleaning, will not influence air-flow and the conveying of powdery paints is acted on, structure is simply easy to implement, fits In popularization and application.
