Abstract
The utility model discloses a calcium stearate's device is directly produced to aqueous phase, including reation kettle, centrifugal separator, flash drying machine, storage tank and circulating pump, reation kettle is provided with high shear emulsion machine and agitating unit, and the discharge gate of reation kettle below links to each other with the entry end of centrifugal separator, and the liquid outlet end of centrifugal separator is through storage tank, circulating pump, links to each other with the feed inlet of reation kettle top, and the powder exit end of centrifugal separator links to each other with the flash drying machine. The utility model discloses stirring that the in -process of effectively having solved aqueous phase direct method production calcium stearate exists is inhomogeneous, reaction time long and free acid content high scheduling problem, can make the production time shorten to 10 -15 minute by a wide margin, and the free acid content of product is low, and the granule is tiny, has reduced calcium stearate's unit product energy consumption and water bad news by a wide margin to the emission of waste water has been avoided.
Description
Technical field
The utility model relates to the technical field of stearate production equipment, particularly relates to a kind of device of aqueous phase direct production calcium stearate.
Background technology
Calcium stearate is the one of metallic soap of stearic acid, and having been widely used in fields such as plastics, detergents and cosmetic, coating, is one of main ingredient of polyvinyl-chloride use environment-friendly calcium-Zn composite heat stabilizer.At present, the production method of calcium stearate mainly contains double decomposition, scorification and aqueous phase direct method.Wherein, aqueous phase direct method is with stearic acid and calcium hydroxide (or calcium oxide) for raw material directly synthesizes calcium stearate in water medium, and it has the advantages such as reaction conditions gentleness, production cost be lower.
But adopt the conventional production equipment comprising mechanical agitation type reactor to carry out aqueous phase direct method and produce calcium stearate, stirring efficiency is lower, causes stirring uneven; In reaction process, along with solid phase prod calcium stearate levels increases, solid particulate in reaction system increases, part material stearic acid is wrapped, cause the reaction times longer (1-3 hour), and the free acid content of product is too high, have a strong impact on the quality of product, constrain the large-scale application that aqueous phase direct method produces calcium stearate.In addition, reusing of the waste water produced in production process do not considered by the production unit of existing calcium stearate, makes the water loss of unit product higher, and cause a large amount of discharges of waste water.Therefore, for enterprise and the technician of this area, the device developing a kind of aqueous phase direct production calcium stearate that can solve the problem has very important significance.
Summary of the invention
The purpose of this utility model is to provide a kind of device of aqueous phase direct production calcium stearate, and to solve, the stirring existed in the process of aqueous phase direct method production calcium stearate is uneven, long reaction time, free acid content are high, product particle is large, drying process power consumption is high and filtrate can not reusable technical problem.
The technical solution adopted in the utility model is: a kind of device of aqueous phase direct production calcium stearate, comprise reactor, whizzer, flash dryer, storage tank and recycle pump, described reactor is provided with high-shear emulsion machine and whipping appts, discharge port below reactor is connected with the inlet end of whizzer, the liquid exit end of whizzer is connected with the inlet end of storage tank, the powder exit end of whizzer is connected with flash dryer, the exit end of storage tank, through recycle pump, is connected with the opening for feed above reactor.
Described high-shear emulsion machine is positioned at the agitator arm both sides of reactor, is symmetric.
The utility model efficiently solves the aqueous phase direct method problem that to produce in the process of calcium stearate that the stirring that exists is uneven, long reaction time, free acid content are high, product particle is large, drying process consumes energy high, the production time can be made significantly to foreshorten to 10-15 minute by original 1-3 hour, the free acid content of product is low, particle is tiny, significantly reduce energy consumption of unit product and the water consumption of calcium stearate, and avoid the discharge of waste water.
Accompanying drawing explanation
Fig. 1 is production equipment overall schematic of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
The utility model discloses a kind of device of aqueous phase direct production calcium stearate, it comprises reactor 1, whizzer 2, flash dryer 3, storage tank 4 and recycle pump 5, reactor 1 is provided with high-shear emulsion machine 6 and whipping appts 7, high-shear emulsion machine 6 is positioned at whipping appts 7 both sides of reactor 1, is symmetric; Discharge port below reactor 1 is connected with the inlet end of whizzer 2, the liquid exit end of whizzer 2 is connected with the inlet end of storage tank 4, the powder exit end of whizzer 2 is connected with flash dryer 3, and the exit end of storage tank 4, through recycle pump 5, is connected with the opening for feed above reactor 1.
The above is preferred implementation of the present utility model, can not limit the interest field of the utility model with this.It should be pointed out that for those skilled in the art, the technical solution of the utility model is modified or equivalent replacement, do not depart from protection domain of the present utility model.
