Abstract
A bottom-diversion high-efficiency and energy-saving mixing device used in the blending of the liquid in a fixed container uses a radial flow-typed mixing impeller; the midpoint of the leaf width is arranged in the place one tenth to one fifth from the liquid surface; the bottom of the container is provided with a radioactive diversion baffle with a special curved surface; thus the radial liquid produced by the rotation of the impeller can return to the bottom of the container after being impacted by the inner wall of the container; the liquid is gathered and lifted towards the center according to the shape of the arranged baffle to produce an upward spiral central flow; thus the original flow typed is changed into a more complex mixed flow; and the device reaches the mixing effect equal to the whole baffle but with the low energy consumption.
Description
Technical field: the utility model relates to a kind of agitating device that the lifting of liquid mixed process generation center is flowed in fixed container.Especially mix requirement at different medium, adopt four kinds of different bottom water conservancy diversion barrier forms respectively, produce energy-efficient mixing effect.
Background technology: existing agitating device all adopts agitator arm, and the rotation by impeller transfers to surrounding liquid with energy, produces liquid stream, promotes liquid and circulates in container along certain path, wishes to produce the mixing flow pattern from radial and axial all directions.Existing common practice is to settle the vertical plate washer of several certain widths around the container on the inwall, when baffle dimensions size and quantity meet certain requirements, is called full baffle plate, and under full baffle plate condition, mixed effect the best will increase 4-5 doubly but stir power consumption, and it is bigger to consume energy.
Summary of the invention: the purpose of this utility model is to propose a kind of mixed type circulating fluid that causes, and mixed effect is good and stir energy-efficient agitating device low in energy consumption.
Can realize the purpose of this utility model by following technical proposals, a kind of energy-efficient agitating device, it comprises container, radial type agitator arm, it is characterized in that, be that fulcrum is provided with the water conservancy diversion plate washer that is radial arrangement on the container bottom surface with its center.
In order to reach effect preferably, agitator arm (starting at its blade mid point) places from liquid level 1/10-1/5 degree of depth place, connects guide shell in the agitator arm bottom.
The water conservancy diversion plate washer is 4 kinds of curve forms, or parabolic type or log spiral type or involute-type or circular arc type, their and average angle distributions vertical with container bottoms.
The beneficial effects of the utility model are: the flow apron of placing the emanant layout of special curve form at container bottom, the liquid that makes runoff produce flows when the bump container inner wall returns container bottom, be subjected to the guide effect of the shape of set baffle plate, liquid flows to the center and compiles and rotate, produce the spiral center stream that upwards promotes, the direction of rotation of center stream is consistent with impeller, is attracted and enter the water conservancy diversion that is connected in the impeller lower end to connect guide shell in the agitator arm bottom by impeller eye when rising to certain altitude near impeller.Be subjected to the impeller centrifugation accelerates to produce radial flow in the tube once more, thereby medium is constantly dispersed, change original flow pattern, form the comparatively mixed flow of complex loops, avoided the lamination of " short circuit " phenomenon and radial flow, reached the purpose that mixes.Through experimental verification, the power levels number of the agitator arm of mensuration is 2-2.5 times when not adding baffle plate, is about 1/2 under the full baffle plate condition, and mixed effect is suitable with full baffle plate condition, with the less higher stirring efficiency of energy consumption acquisition.
Description of drawings: the utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the vertical section structure sketch of an embodiment of the present utility model.
Fig. 2 is the embodiment vertical view of four kinds of forms of water conservancy diversion plate washer of bottom radiation layout.
Among Fig. 11, agitator arm, 2, guide shell, 3, container, 4, flow apron.
(a) parabola radial pattern plate washer among Fig. 2, (b) log spiral type radial pattern plate washer, (c) involute-type radial pattern plate washer, (d) circular arc type radial pattern plate washer.
The specific embodiment: referring to accompanying drawing 1,2, be provided with water conservancy diversion plate washer 4 in the bottom of container 3, it is that fulcrum is radial average angle arranged distribution with container 3 centers.Water conservancy diversion plate washer 4 has four kinds of forms, i.e. parabolic type plate washer, log spiral type plate washer, involute-type plate washer, circular arc type plate washer.Water conservancy diversion plate washer 4 is vertical with the bottom surface of container 3, and general quantity is 4, adopts welding or bolting in the container bottom surface.Agitator arm is a radial type, and it places container 3, its bottom guide shell 2 that is fixedly connected, and the blade mid point plane of agitator arm 1 places apart from the degree of depth place of medium liquid level 1/10-1/5.Guide shell 2 is a metal thin shell cylinder.
Fig. 1 is one of the present utility model and implements general rule, and during practical application, according to the vessel volume size, the physical property of medium viscosity and suspended particulate etc. design the width and the length of agitator arm size, rotating speed, draft tube diameter and width and water conservancy diversion plate washer.The curve form of flow apron is also selected each embodiment of Fig. 2 respectively according to above-mentioned condition of work, promptly adopt: parabolic type or log spiral type or involute-type or circular arc type etc.
Claims (3)
1, the energy-efficient agitating device of a kind of bottom flow-guiding type, it comprises container, the radial type agitator arm is characterized in that, is that fulcrum is provided with the water conservancy diversion plate washer that is radial arrangement on the container bottom surface with its center.
By the energy-efficient agitating device of the described flow-guiding type of claim 1, it is characterized in that 2, the radial type agitator arm places the position of container to be the degree of depth place with blade mid point plane separation medium liquid level 1/10-1/5, connects guide shell in the agitator arm bottom.
3, by claim 1 or the energy-efficient agitating device of 2 described flow-guiding types, it is characterized in that the water conservancy diversion plate washer is 4 kinds of curved surface forms, or parabolic type or log spiral type or involute-type or circular arc type, their and average angle distributions vertical with container bottoms.
