Abstract

The utility model discloses a stirring evaporator, comprising a stirring rod (3), a stirring evaporative kettle (9), and a flow guiding funnel (6). The other end of the blades (5, 7) connected with the stirring shaft (3) of the evaporative kettle (9) is connected with the funnel (6); the blade (5) of the upper layer is connected with the upper end of the funnel (6); the blade (7) of the lower layer is connected with the lower part of the flow guiding funnel (6); the upper part of the internal diameter of the flow guiding funnel (6) is big, and the lower part of the internal diameter of the flow guiding funnel (6) is small; over two pieces of the flow guiding plate (4)which is axisymmetric and is the top and bottom trend are arranged in the flow guiding funnel (6). When the blades rotate, the centrifugal force make the liquid contacting with the flow guiding plate in the flow guiding funnel generate an upward attraction because the upper part of the flow guiding funnel (6) is big, and the lower part of the flow guiding funnel (6) is small.

Description

Stir vaporising device

Technical field

The utility model relates to a kind of stirring vaporising device, especially relates to a kind of stirring evaporating kettle.

Background technology

In the stirring evaporating kettle that uses at present, in the process that generally all exist in heating, stirs, evaporating kettle top heat transfer area can not make full use of, and makes that the thermal efficiency that stirs evaporating kettle is low, causes the phenomenon of energy waste simultaneously; This mainly is because along with after the liquid in kettle evaporation reduces, and liquid material reduces gradually with the contact area that stirs the evaporating kettle heat-transfer area and causes.

Summary of the invention

The purpose of this utility model is to stir the original heat transfer area of evaporating kettle in order to make full use of, guarantee that liquid reduces in the kettle after, liquid material with stir evaporating kettle bigger heat transfer contact area still can be arranged, thereby improve the thermal efficiency that stirs evaporating kettle; Be convenient to simultaneously the cleaning of whole agitating device again, and a kind of stirring vaporising device of design.

The technical scheme that the above-mentioned purpose of finishing the utility model adopts is: a kind of stirring vaporising device comprises the stirring evaporating kettle of shaft and multi-layer oar blade also comprising the water conservancy diversion funnel; The other end of the blade that is connected with the shaft of evaporating kettle is connected with the water conservancy diversion funnel, and the upper strata blade connects the top of water conservancy diversion funnel, and lower floor's blade connects the bottom of water conservancy diversion funnel, and the internal diameter of water conservancy diversion funnel is up big and down small; The axisymmetric deflector more than two of trend up and down is set in the water conservancy diversion funnel; The cross section of deflector can be an arc, also can be square or obtuse angle shape; Stirring evaporating kettle can be double-layer paddle, also can be multi-layer oar blade; In stirring evaporating kettle, the cross section of blade can be the flat type that is parallel to shaft, also can be the round of round bar shape.

The beneficial effects of the utility model: because the water conservancy diversion funnel in the agitating device is up big and down small; And in the water conservancy diversion funnel, be provided with up and down the deflector of trend; When agitating device rotates, centrifugal force makes the liquid of contact deflector in the water conservancy diversion funnel produce gravitation upwards, the liquid material of autoclave body bottom constantly is extracted into upper surface in the inner zone of heating scope of kettle by the deflector on the water conservancy diversion funnel, and it is past dirty along kettle top equably, fully contact the heating surface of kettle, improved the thermal efficiency of evaporating kettle greatly.Shorten evaporation time, thereby can not change under the original heat transfer area condition of original agitating function and kettle, improve evaporation efficiency, and energy savings; In addition since the water conservancy diversion funnel on deflector be open, so that the cleaning of whole agitating device.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

In Fig. 1, stir vaporising device: comprise the stirring evaporating kettle 9 of motor 1, decelerator 2, shaft 3 and upper and

lower blade

5,7, also comprise water conservancy diversion funnel 6; What be connected with the shaft 3 of evaporating kettle 9 is upper and lower each four

blade

5,7, the other end of these blades is connected with water conservancy diversion funnel 6, and last blade 5 connects the top of water conservancy diversion funnel 6, and following blade 7 connects the bottom of water conservancy diversion funnel 6, following blade 7 is than last blade 5 weak points, and the internal diameter of water conservancy diversion funnel 6 is up big and down small; Axisymmetric four deflectors 4 of trend up and down are set in water conservancy diversion funnel 6, and the cross section of deflector 4 is a square; Drive blade 5 at

shaft

3,7 when stirring, water conservancy diversion funnel 6 also rotates together, because the internal diameter of water conservancy diversion funnel 6 is up big and down small, the liquid that contacts with deflector 4 on the water conservancy diversion funnel 6 is under action of centrifugal force, upwards flow along deflector 4, thereby the liquid of autoclave body bottom is extracted into continuously the top of water conservancy diversion funnel 6, and evenly be sprayed at kettle top and have in the zone of zone of heating 8, though like this along with liquid evaporation back amount of liquid reduces gradually, but because the continuous action of the deflector 4 on the water conservancy diversion funnel 6, thereby assurance liquid contacts fully with heating region, has improved the evaporation efficiency of evaporating kettle 9.

In Fig. 1 along A-A as shown in Figure 2 to view: in the stirring evaporating kettle 9 of zone of heating 8 is arranged, be provided with axisymmetric four deflectors 4 of trend up and down on the water conservancy diversion funnel 6, the cross section of deflector 4 is a square, is connected the bottom of water conservancy diversion funnels 6 by blade under axisymmetric four flats of shaft 3 drivings 7;

Deflector cross section among the embodiment of the present utility model on the water conservancy diversion funnel be arc structure as shown in Figure 3: on water conservancy diversion funnel 12, the cross section of deflector 11 is an arc.

Deflector cross section among the embodiment of the present utility model on the water conservancy diversion funnel be obtuse angle shape structure as shown in Figure 4: on water conservancy diversion funnel 14, the cross section of deflector 13 is an obtuse angle shape.

In embodiment of the present utility model, the blade that stirs evaporating kettle can be a bilayer as shown in Figure 1, also can be multilayer; Blade can be the blade of flat, also can be the round bar of tubulose; The quantity of blade can be as shown in Figure 2 four, also can be axisymmetric two, three, five, or multi-disc more; The quantity of the deflector on the water conservancy diversion funnel can be as shown in Figure 2 four, also can be axisymmetric two, three, five, or multi-disc more; The cross section of the deflector on the water conservancy diversion funnel can be a square as shown in Figure 2, also can be as shown in Figure 3 arc or obtuse angle shape as shown in Figure 4.
