Technical field

The present invention relates to the mixing apparatus of plurality of liquid material, be especially applicable to the numerical control on-line continuous blender of liquid-liquid, the mediation of liquid-a small amount of solid, dispersion, emulsification and microemulsified.

Background technology

In the production process of oil product, need to be in harmonious proportion evenly to plurality of raw materials, in order to ensure product quality output, need various material rapid mixing even.Present stage commercial mixer, mixing apparatus volume is large, and incorporation time is long, and production efficiency is lower, and equipment funds input is very large.

Summary of the invention

For overcoming the defect of current many blenders, adapt to the needs that industry energy conservation consumption reduction is produced, the technical problem to be solved in the present invention is the on-line continuous mixing apparatus providing a kind of dependable performance, good mixing effect, production efficiency high, to reduce the input of equipment and to ensure product quality.

The present invention solves the problems of the technologies described above and adopts following technical scheme: a kind of numerical control on-line continuous blender, comprise vertical tank body, motor and agitating device, it is characterized in that: in vertical tank body, horizontal direction is provided with 2-4 block annular diaphragm plate, tank body is divided into the relatively independent stirring layer of 3-5 layer by annular diaphragm plate, annular diaphragm plate center is provided with through hole, the several curving groove of through hole edge, agitating device comprises shaft and is installed on 3-5 agitator on shaft, an agitator is positioned at one deck and stirs layer, and motor is numerical control variable frequency motor.

Annular diaphragm plate is evenly provided with sieve aperture; In order to ensure the load performance of tank body, ellipse head is established in tank body bottom, and oval capping is installed on tank body top.

The 2-4 block annular diaphragm plate installed in tank body, is divided into the stirring layer that 3-5 layer is relatively independent, increases the effect of blender micromixing by blender; Adjacent annular diaphragm plate spacing is fixed in tank body uniformly, the through hole that annular diaphragm plate center is provided with, agitator is coordinated to install, several palintrope skewed slots of annular diaphragm plate through hole edge, to tear hydroenhancement microcosmic immixture, increase agitator to the shear-mixed effect of fluid, on annular diaphragm plate, have sieve aperture simultaneously, increase the mixing of adjacent stirring inter-layer fluid, reduce agitator resistance to a certain extent, increase mixed; Simultaneously in whipping process, because each stirring interlayer pressure is different, the fluid effect of being stressed, also vertically spray into another layer by sieve aperture in little a fluid stream mode, dispersing liquid particle, then mix with horizontal flow in another layer, form microcosmic cross-flow, promote mixed further.

Blender adopts bottom in and top out continuously-running duty; material can be passed through premix and enters tank body by an import; or various materials is directly entered tank body by 2-4 the import be distributed on below tank body; enter in blender along tank body tangential direction level; automatically horizontal vortex is produced by the horizontal tangent speed of fluid; reduce agitator and stir resistance, protection agitator, reduction stir energy consumption.

The on-line continuous mixing apparatus that the present invention is a kind of efficient, low consumption, applicability is wide, can be used for the dissolving of material in all kinds of oil product, food processing, brew and chemical products production process, emulsification, dispersion and mediation, substitute blending tank used or emulsion tank in prior art mixed process, equipment volume is little, production capacity is large, can equipment investment be reduced, increase substantially production efficiency, ensure product quality.

Detailed description of the invention

As shown in Figures 1 and 2: a kind of numerical control on-line continuous blender, comprise vertical tank body 1, motor 5 and agitating device, in vertical tank body 1, horizontal direction is provided with three pieces of annular diaphragm plates 4, vertical tank body 1 is divided into four layers of relatively independent stirring layer 101 by annular diaphragm plate 4, annular diaphragm plate 4 center is provided with through hole 401, through hole 401 edge six curving grooves 402, agitating device comprises shaft 2 and is installed on four agitators 3 on shaft 2, an agitator 3 is positioned at one deck and stirs layer 101, and motor 5 is numerical control variable frequency motors.

See Fig. 3 and Fig. 4: annular diaphragm plate 4 is evenly provided with sieve aperture 403; In order to ensure the load performance of vertical tank body 1, ellipse head is established in vertical tank body 1 bottom, and oval capping 6 is installed on vertical tank body 1 top.

In order to prevent shaft 2 eccentric and bend in whipping process, see Fig. 1, vertical tank body 1 bottom welding has support 7, and shaft 2 lower end by bearings is arranged on support 7; See Fig. 5 and Fig. 6, orlop agitator 301 is oblique leaf open turbine formula structure, and the number of blade six, produces radial and axial mixed flow in whipping process, and while mixing, propelling fluid flows from bottom to top; See Fig. 7 and Fig. 8, intermediate layer agitator 302 is palintrope leaf disc turbotype structure, central disc stops fluid directly to flow through blender, avoid producing the irregular phenomenon of local mixing, it is little that palintrope impeller structure stirs resistance, increase the adaptability of fluid negotiability and fluid viscosity, also can be used for the mixing continuously fast of medium-viscosity material; See Fig. 9 and Figure 10, the superiors' agitator 303 is straight leaf open turbine formula structure, has shearing and mixed, ensures the Homogeneous phase mixing of fluid both macro and micro.

Agitating device, by numerical control variable frequency driven by motor, requires adjusting rotary speed according to the character of mixed material and mixing, improves blender to the adaptability of fluid, reduces energy consumption.

Vertical tank body 1 bottom is provided with material inlet 102 and the cylinder inboard wall of material inlet 102 inlet duct and vertical tank body 1 is tangential direction, makes full use of the kinetic energy pumping into fluid, reduces and stirs resistance, reduces the loss of shaft; According to mixing needs, material inlet 102 can arrange two to four, various materials is directly entered tank body by two to four material inlets be distributed on below tank body, the present embodiment is provided with two each material inlets, material inlet 102 may also be one, and material enters tank body and fully mixes further after premix; Material outlet 601 be positioned at oval capping 6 top and with oval capping 6 plan vertical, material vertically flows out from end socket, the material mixed is made directly to enter in follow-up equipment, because the present invention adopts the continuous operation mode of bottom in and top out, material outlet is without the need to mounted valve, blender is in the mode of operation of the canful of fluid continuous-flow always, overall operation resistance is minimum, energy consumption is minimum, in running, feed rate size can be regulated as required, change the mixing time of staying, reach the mixed effect of needs.
