Background technology
Existing reactor comprises the compositions such as several feed inlet and outlets, the shaft in the kettle and paddle that driving mechanism, the kettle on kettle, the kettle is outer.In order to improve the stirring efficiency of reactor, be provided with paddle in the shaft bottom, can stir shearing to material.Chinese patent discloses a kind of reactor (Granted publication number: CN 101249413A), it comprises kettle and agitating device, agitating device comprises shaft and paddle, paddle is fixed on the lower end of shaft, the upper end of shaft by bearing with the hub setting of cantilever form ground on the roof of kettle, the top ends of bearing that shaft is stuck in and drive unit transmission connect, in the portion on the upper side of the axis body of kettle that shaft is positioned at the one deposition umbrella that is used to admit the dirt that comes from bearing wear and produce is installed, the deposition umbrella maintains the distance of 10～25cm between the position on the shaft and item wall; The deposition pack is drawn together umbrella body, support member and securing member, the top expansion of umbrella body is set as horn body, the narrow tubular body that shortens in bottom, tubular body is nested with on the axis body of described shaft, support member is located on the umbrella body, securing member is fixed on the support member and by the transition of support member tubular body and shaft is fixed, the global shape of umbrella body is funnel-form, the umbrella body is to be made of the felt more than one deck at least, the thickness of every layer of felt is 1.5～2.5mm, the felt of felt for forming through needing machine acupuncture by polyster fibre, support member is a steel wire net rack, securing member is static line or hoop.But this reactor is when work, and material only is to enter then from feeding mouth to stir through paddle, discharging then, and stirring is sheared complete inadequately, can not reach the requirement of high dispersive.
The utility model content
The utility model technical issues that need to address provide a kind of high dispersive and mix the type reactor entirely, it mainly is to solve the existing in prior technology reactor when work, material only is to enter then from feeding mouth to stir through paddle, discharging then, stir to shear fully inadequately, can not reach the technical problem of the requirement etc. of high dispersive.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
High dispersive of the present utility model is mixed the type reactor entirely, comprise reactor, be provided with rotating shaft in the reactor, rotating shaft is by motor-driven, it is characterized in that described rotating shaft is connected with paddle, be evenly equipped with on the inwall of reactor 8 and with last in reactor the spray distribution device of spraying of material, the spray distribution device is connected with the outer circulation pump by pipeline, the outer circulation pump is communicated with the discharging opening of reactor again.Reactor includes the kettle cover of kettle and kettle upper end, is connected with charging aperture on the kettle.Material stirs after high pressure outer circulation pump is ejected in the reactor once more by the spray distribution device through paddle is preliminary, because expulsion pressure is stronger, so paddle is more complete when stirring is sheared.The outer circulation pumpage can be 300m
3/ hour, outlet pressure can be 2～15kg/cm
2After stirring was finished, material can be discharged from the discharging opening that reactor is provided with.
As preferably, described spray distribution device comprises the cylinder that has suction inlet, and the cylinder upper end is connected with the outer circulation pump by pipeline, and the cylinder lower end is shrunk to funnel type, and the funnel lower end is connected with upwards the jet to the reactor inner bending.The cylinder lower ending opening is less, makes that material pressure when spraying is bigger, helps being sheared.All spray distribution devices all are arranged in reactor inwall circumference, and its jet is all aimed at the reactor center.
As preferably, the angle α of described jet and spray distribution device axis is 40～45 °.Jet is tilted upward, and it can aim at the reactor center.
As preferably, described paddle is two-layer, and the upper strata is for mixing oar, and lower floor distributes oar for shearing, and mixes oar, shears and distribute oar all to be connected in the rotating shaft.Can aim at lower floor after the jet bending and shear distribution oar place.Can shear the shearing of distribution oar with the material that comes out from jet by the material of upper strata mixing oar like this.The discharge capacity of shear distributing oar be 3 ten thousand steres/hour, the discharge capacity of mixing oar be 5 ten thousand steres/hour.
As preferably, the spacing of the jet of described spray distribution device and reactor bottom is 2～6m.The position height of spray distribution device is very crucial, and it need avoid stirring in the still the relative negative pressuren zone that produces.The height of all spray distribution devices is all identical.
As preferably, the diameter of described reactor is 1～4m, and the height of reactor is 6～12m.
Therefore, the utlity model has and on the inwall of reactor, add a plurality of spray distribution devices, make reactor when work, the ejection pressure of material strengthens, shear comparatively thoroughly, and by two-layer paddle, make mixing effect better, can reach the requirement of high dispersive, characteristics such as simple and reasonable for structure.
