Abstract
The utility model relates to a kind of stirring rake structure, comprises stir shaft, stir shaft is fixed with oar body, and oar body is in " people " word structure, and its root is wire-wrapped in the periphery of stir shaft, and the top of oar body is fixed with blade; Oar body is 360 ° of Spiral distributions arrangements around the axis of stir shaft, and helix angle is 15 ~ 30 °, and the angle of two adjacent oar body medullary rays is 30 °, and in side, distance between centers of tracks is 300mm; Oar body is to tank body tail end lopsidedness, and the angle of the axis of oar side center line and stir shaft is 75 ~ 85 °.The utility model strengthens the oar body of oar body and the syndeton of stir shaft, also strengthens the strength of joint of oar body and stir shaft simultaneously, prevents oar body deformability, improve the stirring plug-flow efficiency of oar body.
Description
Technical field
The utility model relates to a kind of whipping appts, relates in particular to anaerobic fermentation tank stirring rake structure.
Background technology
Producing methane through anaerobic fermentation technology, its principle is for fermentation bed material with organic waste (farming stalk, feces of livestock and poultry, solid-state fluorescence material etc.), under anaerobic, utilize anaerobion that the organism in organic waste is changed into biogas, liquid natural pond, remaining natural pond slag can be used as fertilizer for plant husbandry.
Pulling flow type anaerobic reactor utilizes fresh fermentation substrate to form plug-flow to during the reactor feed of circular or square-section, and substrate adopts the flap of oar body or particular design to stir in the vertical direction of material plug-flow.Plug-flow reactor is stirred by adjustment and handling equipment can be suitable for doing, wetting two kinds of zymotechniques; And plug-flow can be formed the digestive process stage automatic separation, without the formation of heap sum settled layer, without short flow phenomenon.
The stirring rake of current anaerobic reactor is directly welded on stir shaft by oar body, because the contact surface of stir shaft and oar body is too little, and oar body is direct rod shape, when stirring, the rotation of stir shaft and the resistance of oar body and fermentation substrate, the opposite direction distortion that oar body can be caused to rotate to stir shaft, makes the inwall spacing of oar body top and anaerobic fermentation tank strengthen further, finally make the effect of oar body plug-flow fermentation substrate decline, cause stirring efficiency low.
Utility model content
Technical problem to be solved in the utility model is, improve the structure of existing stirring rake, increase the yield strength of welding site, strengthening oar body of oar body and stir shaft, make the oar body of stirring rake when stir shaft rotates, the generation of the situation such as avoid the flexural deformation of oar body or come off, ensure the plug-flow effect of oar body, improve stirring efficiency.
For achieving the above object, the utility model by the following technical solutions.Stirring rake structure, comprises stir shaft, stir shaft is fixed with oar body, and oar body is in " people " word structure, and its root is wire-wrapped in the periphery of stir shaft; The top of oar body is fixed with blade; Oar body is 360 ° of Spiral distributions arrangements around the axis of stir shaft, and helix angle is 15 ~ 30 °, and the angle of two adjacent oar body medullary rays is 30 °, and in side, distance between centers of tracks is 300mm; Oar body is to tank body tail end lopsidedness, and the angle of the axis of oar side center line and stir shaft is 75 ~ 85 °.
The utility model has the advantage of, strengthen the oar body of stirring rake and the syndeton of stir shaft, also strengthen the strength of joint of oar body and stir shaft simultaneously, prevent the flexural deformation of oar body or come off, improve the stirring plug-flow efficiency of oar body.
Accompanying drawing explanation

Fig. 3 is the side-view of single-piece oar body and stir shaft connection state in the utility model.
In figure: 1. stir shaft, 2. oar body, 3. blade, 4. tank body tail end.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.See Fig. 1 to Fig. 3, stirring rake structure, comprises stir shaft 1, stir shaft 1 is fixed with oar body 2, and oar body 2 is in " people " word structure, and its root is wire-wrapped in the periphery of stir shaft 1, and the top of oar body 2 is fixed with blade 3; Oar body 2 is 360 ° of Spiral distributions arrangements around the axis of stir shaft 1, and helix angle is 15 ~ 30 °, and the angle α of two adjacent oar body 2 medullary rays is 30 °, and in side, distance between centers of tracks L is 300mm; Oar body 2 is to tank body tail end 4 lopsidedness, and the angle β of the axis of oar body 2 side center line and stir shaft 1 is 75 ~ 85 °.
embodiment:a better embodiment of the present utility model is as follows: one is applied to horizontal type anaerobic fermentor tank and (adopts horizontal plug-flow technique, fermenter volume 13m
3) in stirring rake structure.In this structure, stir shaft 1 length is 7000mm, and diameter is 219mm; By distance between centers of tracks L in the side of oar body 2 be 300mm calculate, whole stir shaft 1 is welded with 23 oar bodies 2, and the axis angle β of oar body 2 side center line and stir shaft 1 is 80 °.Stirring arm 2 is made up of band steel, its width 50mm, thickness 12mm, length 562mm, and the root of stirring arm 2 is wire-wrapped in the periphery of stir shaft 1; Oar body 2 is 360 ° of Spiral distribution arrangements around the axis of stir shaft 1, and helix angle is 25 °, and the angle α of two adjacent oar body 2 medullary rays is 30 °.Blade 3 is made up of band steel, and its dimensions length is 120mm, width is 50mm, thickness is 12mm; Blade 3 is fixedly welded in two top clampings place of stirring arm 2.The utility model structure solves and was directly welded in rotating shaft by oar body 2 in the past, and the phenomenon occurring flexural deformation or come off, the stirring plug-flow efficiency of oar body 2 have also been obtained raising.
