Paint stirring blend tank
Technical field
The present invention relates to a kind of blend tank, specifically refer to paint stirring blend tank.
Background technology
The allotment of paint needs to stir in heat-processed, otherwise easily coking and dead angle occurs, when the viscosity painted is very big, stir and not easily carry out, thus present paint deployment tank be all to Large Copacity, high solid-liquid ratio, strong mixing be developing direction, but also exist stir that electricity consumption is big, material sedimentation easily stuck, be difficult to eliminate the defect stirring dead angle.
Present paint deployment tank generally all adopts major axis multilayer sweep stirring at low speed, motor configuration power is big, agitator shaft speed about 1 turn/second, stirring rake radius are slightly less than tank body internal diameter, exist paint easily sink to the bottom, have a power failure material sedimentation can stuck stirring even cannot start defect, electricity consume very high, thus existing whipping appts can not meet the technical requirements of high viscosity, large size paint deployment tank.
Summary of the invention
The technical problem to be solved in the present invention overcomes the deficiencies in the prior art exactly, the each road technique that provide a kind of less energy-consumption, paint deployment can be completed, material circulates very well, not easily sink to the bottom, and having a power failure even if long-time causes the material sedimentation also can the paint stirring blend tank of light-load starting.
For overcoming the deficiencies in the prior art, the present invention takes following technical scheme:
A kind of paint stirring blend tank, comprise tank body, motor and step-down gear and stir shaft, in stir shaft insertion tank body, motor and step-down gear drive stir shaft to rotate, it is characterized in that: stir shaft is followed successively by from lower to upper sweeps jet flow agitator under end agitator, plural serial stage, two-way jet flow agitator and the lower jet agitator that suspends, the lower jet agitator that wherein suspends limits by upper and lower positioning step, can fluctuate; Tank is external is provided with chuck, and chuck connects steam valve, drain valve and inline valve, and chuck is also connected with water intaking valve and return water pipe control valve; Tank base is connected Middle pressure draught fan and is provided with paint delivery valve.
Described end agitator of sweeping comprises stir shaft, interior cylinder and urceolus, and stir shaft and interior cylinder are welded as a whole through axial blade, and interior cylinder extends to cone cylinder downwards, and cone cylinder is welded by fagging with urceolus; Interior cylinder inwall is welded with circulation blade, cone cylinder inwall is welded with centrifuge scraper.
Under described plural serial stage, jet flow agitator is in series by 2-10 lower jet flow agitator, and lower jet flow agitator comprises stir shaft and urceolus, and stir shaft and urceolus flow down spray blade through liquid and be welded as a whole.
Described two-way jet flow agitator comprises stir shaft, interior cylinder and urceolus, and stir shaft and interior cylinder flow down spray blade through liquid and be welded as a whole, and interior cylinder and urceolus spray blade on liquid stream and be welded as a whole.
Under described suspension, jet agitator comprises stir shaft, axle sleeve and urceolus, and stir shaft is splined shaft, and axle sleeve is also spline axle sleeve, and spline axle sleeve can move on splined shaft; Spline axle sleeve and urceolus connect as one through blade.
Described tank body is provided with manhole, is convenient to maintenance, observation and throws material.
When needs carry out process for processing, open motor and step-down gear, rotating speed in actual applications 3-15 p.s. turn can adapt to great majority use needs, progressively add material again, the lower jet agitator that suspends can fluctuate on the splined shaft between upper and lower positioning step flexibly, suspend lower jet agitator by the reverse towing force of gravity, downwards jet flow liquid and splined shaft and spline inner room frictional force acting in conjunction, can suspend stirring by relative liquid surface certain position, downward jet flow; Two-way jet flow agitator rotates, wherein liquid flows down the spray downward jet flow of blade, and liquid stream sprays blade upwards jet flow, and under suspending, jet agitator and two-way jet flow agitator produce the core flow decline of upper liquid jointly, liquid stream sprays blade to upper annular jet flow, make top convection current situation good.
Multiple downward tandem injection liquid of lower jet flow agitator, enter and sweep end agitator and accelerated downward conveying once again by axial blade, liquid is rotated speed-raising and is had remarkable circulation when flowing through circulation blade, becoming the integrated fluid of axial flow, circulation, the direct punching of core flow high speed carries out center to bottom and sweeps the end, and a part of centrifugal stream is centrifuged blade and rotates speed-raising once again, form tubaeform injection stream high speed diffusion, impact base plane, play big area without dead angle sweep the end stir, prevent material sedimentation.
The different process segments, need to carry out different parameters regulation and control, commitment material viscosity can be opened greatly valve and carry out the steam heating that indirectly heats up work efficiency is improved, if desired can start Middle pressure draught fan when heating up applicable and carry out rare gas element internal recycle, rare gas element from blower fan adds by the bottom of tank, mix and scatter in cone is bucket-shaped from stirring downward streams, rare gas element carries material and forms rising mixed solution stream in tank wall, so tank is formed centrally katabatic drainage, stirring region outside forms upwelling, form perfectly paint underflow convection circulation, after completing processing, product deployed in tank is cooled by Open valve cold water fast, opening paint delivery valve, can to implement lower step filling.
Compared with prior art, the useful effect of the present invention is also:
Center liquid axial flow from top to bottom series connection speed-raising always impact bottom downwards, make bottom well material suspended, can not sedimentation; The electric power consumed preferentially carries out liquid stream and sweeps end elimination sedimentation, then lets nature take its course to be converted to stirring again, makes liquid phase solid phase in whole bucket substantially even, and this kind of principle of work had both met service requirements, key significantly energy-conservation again.
The lower jet agitator that suspends suspends to stir and automatically adapts to different liquid level, completes to stir.
Axial force fully considers that gravity balances simultaneously mutually, reduces the detrimentally affect to transmission.
The bottom bucket-shaped jet flow of cone coordinates central jet, perfect realization sweeps the end, prevent sedimentation, little owing to stirring radius, even if material viscosity is very big, drag torque is also very little, therefore can stir by light start, entering normal whipped state, noble gas mixtures stream forms the perfect convection circulation of paint underflow further.
The scull leaf middling speed rotation that axial flow uses, electricity consumption is very low, and mixing effect is fine, particularly sweeps the urceolus of end agitator and bores cylinder when higher rotation speed, and internal and external walls liquid can play liquid-bearing supporting role, makes stirring reliable and stable.
