Abstract

This multi-functional stirring device is a single-shaft, single-motor stirring device composed of a high-speed stirrer inside the guide tube and a low-speed stirrer outside the guide tube. It can make the material produce both axial flow and radial flow in the mixing tank, and it can also stir near the tank wall. There is no dead zone in the whole mixing tank, and the mixing is uniform and the mixing effect is good. The agitation process of the material also produces high shear action, so it has multiple functions such as crushing, dispersing, mixing, emulsifying and so on. The single-axis rotation has simple structure, easy sealing, and low equipment cost.

Description

Multifunctional mixer

The utility model belongs to the mixing plant of material.

Stirring is the unit operation of Chemical Manufacture, has a large capacity and a wide range, and is widely used in each technical fields such as chemical industry, light industry, food.The form of agitating device is a lot, can be divided into following several types according to shaft: the single shaft uniflow type, have only single shaft as shown in Figure 2, and agitator rotation makes the groove inner fluid cause single axial flow pattern or flow pattern radially; Single shaft double action type as shown in Figure 3, promptly single shaft, and agitator can rotate and can pump; Represent respectively that as Fig. 4, Fig. 5 two kinds of twin shafts are combined, two shafts are respectively with different rotating speeds with turn to rotation.The mixing effect of two kinds of forms is better than first kind after experimental study shows.But have weak point, single shaft double action type makes the many and sealing difficulty of driving member owing to want agitator rotation and reciprocating motion; And two shafts of the combined need of twin shaft, two cover transmission and gears, two sealing devices.So this transmission mechanism complexity of two types, processing request height, equipment cost increases.

Task of the present utility model provides a kind of agitating device of fixedly single shaft rotating spoon, and its transmission mechanism is simple, and sealing easily, and is cheap for manufacturing cost, reliable operation.The interior material of groove was moved vertically and radially simultaneously, the material at nearly cell wall place also can be stirred, and reach no dead band in the whole groove, and mix, mixing effect is good.

Organization plan of the present utility model: in the agitator outside of rotation at a high speed, a fixing guide shell is arranged, have the water conservancy diversion narrow slit of inclination at the upper face of guide shell, above near narrow slit, a leafy oblique slurry free to rotate is housed, and tiltedly outside the slurry anchor formula stirring blade of fixedlying connected with it is being arranged.When high speed agitator rotates, material sucks in the guide shell, produce axial flow, and when passing through the inclination narrow slit of guide shell upper surface, produce than big shearing force, material is ejected into after the leafy oblique slurry of inclination narrow slit top, make oblique slurry and with its anchor formula paddle that fuses with lower speed and and the direction of high speed shaft direction of rotation rotate, thereby the material at cell wall place is also stirred, reach no dead band in the whole groove, mix.

The advantage of the utility model organization plan: both produced axial flow in the tank diameter, and Radial Flow had been arranged, good mixing effect again.Material produces high shear forces at a high speed by narrow slit, and therefore the fragmentation of favourable material, dispersion have multiple functions such as dispersion, mixing, fragmentation, emulsification.The single shaft rotational structure makes transmission mechanism simple, saves cover transmission, gear and a sealing device than twin shaft fabricated structure, significantly reduces the device fabrication cost.The running of axial restraint single shaft, supreme reciprocating motion down is easy to adopt the mechanically-sealing apparatus of good sealing effect, so is particularly useful for the stirring occasion of poisonous material.

Further specify the embodiment of this programme with reference to accompanying drawing:

Fig. 1 is an organization plan schematic diagram of the present utility model.

Motor 6 drives shaft 8 and high speed agitator 1 rotation that is fixed on the shaft, in the outside of agitator 1 fixed guide shell 2 is arranged, and inclination narrow slit 3 is arranged on the guide shell upper face.In the shaft outside sleeve 9 is arranged, its upper end is fixed on the lid of tank diameter 7, and its lower end and guide shell are fixed, and locate above near guide shell, and the outside of sleeve 9 is with the oblique slurry 5 that can rotate freely, and tiltedly slurry fixedly fuses with anchor formula stirring blade 4 again.After at a high speed the material by narrow slit 3 is ejected into oblique slurry, just make the rotation at a slow speed together of oblique slurry and anchor formula paddle, rotation direction is opposite with the agitator direction of rotation, anchor formula paddle 4 is near the inwall of tank diameter 7, its rotation also can be stirred the material at cell wall place, realize no dead band in the whole tank diameter, mix, respond well.

Claims (3)

1, a kind of agitating device mainly is made up of motor, shaft, agitator, guide shell and tank diameter, it is characterized in that having inclination narrow slit [3] at the upper surface of guide shell, above near narrow slit, a leafy oblique slurry [5] free to rotate is housed, and is tiltedly starching the anchor formula stirring blade [4] that the outside has and it is fixing.

2, agitating device according to claim 1 is characterized in that one and its stationary sleeve (9) are arranged at the top of described guide shell, and tiltedly slurry (5) then is enclosed within the outer surface near guide shell top place's sleeve (9).
