A kind of colloid modification highly effective reaction still

Technical field

This utility model belongs to material reaction still equipment technical field, is specifically related to a kind of colloid modification highly effective reaction Still.

Background technology

It is known that reactor is one of indispensable key equipment in colloid production process, it is mainly by electricity Motivation drive shaft carrys out reaction stirred makes it fully react the material required for obtaining.At present, along with colloid technique Development, people it is also proposed higher requirement to quality and the precision of colloid product, the reactor produced relative to colloid It is also proposed higher requirement, the especially structure at reactor to design, multicomponent colloid raw material to be ensured mixing is all Even, make various modifying agent be combined with each other with raw material, improve colloid cohesive force, and reaction during to temperature, pressure, The parameters such as the dynamics of stirring also to carry out strict control, the production efficient, stable to realize reactor.Existing reactor master Kettle to be included, is arranged on the charging aperture at top, rabbling mechanism and is arranged on the discharge nozzle of autoclave body bottom, during use, first from entering Material is added in kettle by material mouth, then utilizes driven by motor rabbling mechanism to be stirred material, stirs abundant to material After reaction obtains required colloid, i.e. can open baiting valve and the colloid in kettle is discharged from discharge nozzle, but, above-mentioned stirs Mix mechanism use during, due to rabbling mechanism design unreasonable, use during, rabbling mechanism system easily deposit In the bottom at stirring dead angle, particularly reactor and easily stir inequality near the region of reactor outer wall, substantially can not reach Well compounding effect, more can not make modifying agent uniformly mix with raw material cmpletely, makes the viscous force of the colloid of a part reach Less than requiring, the product even resulting in colloid is defective, affects the normal production of colloid, it is impossible to meet and produce needs normally. Therefore, a kind of simple in construction of development is firm, mixing effect is good, batch mixing is uniform, can be effectively improved production efficiency and ensure product The colloid modification reactor of quality is desirability.

Summary of the invention

The purpose of this utility model is to provide that a kind of simple in construction is firm, mixing effect is good, batch mixing is uniform, can effectively carry High efficiency and the colloid modification reactor of guarantee product quality.

The purpose of this utility model is achieved in that and includes charging aperture, discharging opening, supporting leg, kettle, top cover and blender Structure, rabbling mechanism includes buncher and shaft, and shaft is disposed with three layer process oars from top to bottom, respectively One technique oar, the second technique oar and the 3rd technique oar, the first technique oar, the second technique oar and the 3rd technique oar are by three stirrings Leaf forms, and the angle between three paddles of every layer process oar is 120 °, and paddle between two neighbouring technique oars Interlaced layout, the length of the first technique oar and the 3rd technique oar is longer than the length of the second technique oar, at the inner surface of kettle On be vertically symmetrically arranged with block baffle plate, baffle plate be shaped as isosceles triangle, the horizontal center line of baffle plate and the second technique oar Horizontal center line overlaps, and the end edge 10～20mm of drift angle distance the second technique oar of baffle plate is also machined with several on baffle plate Circular eddy current hole.

This utility model simple in construction, by arranging the technique oar of different radii so that technique oar stirring when not It is only capable of the dead angle eliminating stirring thoroughly, the homodisperse degree of material in effective increase whipping process, increase near still The flowing velocity of material at wall, effectively improves stirring efficiency, and baffle plate is while rotating along with technique oar, can be quick Promote material stirring up and down between the layers, increase dispersibility and the intermolecular collision probability of material of material, strengthen The effect of stirring, makes the material mix homogeneously in reactor, reaction fully, meanwhile, technique oar and baffle plate with the use of, technique The colloid raw material of reactor upper and lower different densities can be flowed by oar to intermediate layer, and baffle plate can be to flowing into intermediate layer Raw material carry out stopping and disperseing, thus change the direction of motion of colloid raw material, allow raw material be mixed thoroughly, do not produce layering The phenomenon uneven with stirring, further improves the uniformity of material, to guarantee the bonding force of colloid, improves the matter of colloid Amount, meets the needs of production.
