The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
Embodiment 1:
Extremely shown in Figure 2 as Fig. 1, the soy bean milk making machine of present embodiment comprises head 1, be installed in the motor 2 in the head 1, place the cup 8 of head 1 below, place pulverizing beating apparatus 7 in the cup 6 and the heater (the present embodiment heater places the bottom of cup) that places cup 6 inside or bottom, head upper cover 3 that head 1 mainly is made of plastics and stainless steel (or other metal material also can, as aluminium sheet, iron plate etc.) head lower cover made 4 forms.
In the present embodiment, be provided with support 41 between head upper cover 3 and the head lower cover 4, be provided with seal 91 between head upper cover 3 and the support 41, be provided with seal 92 between support 41 and the head lower cover 4, be provided with seal 91 between head upper cover 3 and the support 41.Its medium-height trestle 41 is mainly used in and connects head upper cover 3 and head lower cover 4, and is used for the installation location of motor 2.The upper end of head lower cover 4 is provided with outside flange 4a, seal 92, support 41, seal 91, head upper cover 3 are bearing on the flange 4a successively, flange 4a is provided with the through hole of fixedly connected head upper cover 3 usefulness, support 41 is provided with corresponding installing hole with head upper cover 3, seal 91,92, by the screw 10 that passes through hole and installing hole they is linked together.Its medium-height trestle 41 is generally plastic rubber bracket, and the lower end of support 41 can be used for locating and installation motor 2.
In addition, the periphery of head lower cover flange 4a is provided with flanging 4b upwards, and support 41 is provided with corresponding draw-in groove 42, and the flanging 4b of head lower cover 4 is plugged in the draw-in groove 42, thereby plays better positioning action.The inboard of support 41 upper ends is provided with positioning convex ring 43, and positioning convex ring 43 is plugged in the inboard of head upper cover 3.Such design also mainly is for better location.
The bottom of support 41 is provided with electric machine support 12, and motor 2 is fixed on the electric machine support 12.Be provided with downward boss 4c at the center of head lower cover 4 bottoms, this boss 4c can extend downwards always, welds together with flow-disturbing parts 12.Also can directly offer through hole, as connector, again flow-disturbing parts 12 be connected or are welded on the lower end of metal tube 5 by seal at through hole weld metal pipe 5 in the bottom of head lower cover 4 or the bottom of boss 4c.
In order to prevent that slurries from entering head inside, connect motor 2 and be provided with seal 94 with the connecting axle 14 of pulverizing beating apparatus 7.Above-mentioned seal 94 is arranged between motor 2 and the electric machine support 12, also can be arranged between electric machine support 21 and plastic cement lower cover 41 and the metal lower cover 4.As shown in Figure 4, seal 94 in the present embodiment is a double tubular, and the inwall of internal layer tube 94a encases connecting axle 22, and the outer wall of outer tube 94b cooperates with electric machine support 21, the inwall of outer tube 94b cooperates with the appearance of motor 2, thereby plays the dual-seal effect between the three.In addition, motor 2 is installed on the electric machine support 21, the below of electric machine support 21 also is provided with silicagel pad 93, after head lower cover 4 is installed silicagel pad 93 and electric machine support 21 are pressed between support 41 and the head lower cover 4, thereby realize motor 2 soft installations, can effectively eliminate alignment error, make motor 2 self-regulations, guarantee the perpendicularity of connecting axle 22 and motor mounting plane.
Flow-disturbing parts 12 are metal hood-like revolution solid of curved surface, are provided with the protrusion element 12a of rule or irregular distribution at the peripheral surface of flow-disturbing parts 12 and basal surface.The basal surface of flow-disturbing parts 12 is about 5~15mm with the minimum spacing of pulverizing beating apparatus 7, pulverizing beating apparatus can be to be higher than flow-disturbing parts basal surface, also can be to be lower than flow-disturbing parts basal surface, be the best to pulverize about distance H=5~10mm that beating apparatus is higher than flow-disturbing parts basal surface generally.Reason is single when pulverizing beating apparatus 7 and being higher than flow-disturbing parts basal surface, because near the negative pressure the blade increases, forms siphonage easily, therefore pulverize and the flow-disturbing effect better.
Secondly, in order to reach best flow-disturbing effect, the long-pending shaft section greater than the upper end of the shaft section of flow-disturbing parts lower end is long-pending.The long-pending ratio of greatest axis sectional area and minimum shaft section is 1.1~10 on the flow-disturbing parts.For example the diameter D1 of flow-disturbing parts upper surface is 28mm in the accompanying drawing 2, and the diameter D2 of lower surface is 70mm.
Embodiment 2:
To shown in Figure 7, present embodiment 2 is as the metal tube 5 of connector different with the connected mode of head lower cover 4 with the difference of embodiment 1 as Fig. 6.Head 1 comprises head upper cover 3, moulds support 4 and head lower cover 4 in the present embodiment, connector is the metal tube 5 that is welded with flanging 51, be provided with sealing ring 6 between the flanging 51 of metal tube 5 and the head lower cover 4, and link together with head lower cover 4 by the flanging 51 of securing member 61 with metal tube 5, prevent that slurries or slag from entering between connector and the head lower cover 4, avoids growing of bacterium.
