Fiberizer

Technical field

The utility model relates to the hermetically-sealed construction of fiberizer, the especially fiberizer of food such as polishing soya-bean milk, Rice & peanut milk or bean powder, ground rice.

Background technology

Food such as soya-bean milk, Rice & peanut milk or bean powder ground rice are very popular, also occurred the soy bean milk making machine of a lot of structure types on the corresponding market or claimed that fiberizer perhaps is called beater.Its principle all is that granular food is pulverized.

But rise in the equipment of pulverization at these; The difficult problem of sealing is particularly outstanding; Especially the sealing between rotary part and the fixed part; The for example sealing between the line shaft of motor and other parts, if adopt the existing mechanical hermetically-sealed construction, then long-term friction must have the chip or the dust of wearing and tearing between the parts of relative motion.And food can not contact this type of chip or dust, in order to avoid contaminated.For solving this difficult problem; In the prior art or motor is installed in the loam cake of complete machine, reinforced in the cup of bottom then, cover the loam cake processing of polishing; Utilize the gravity effect of material like this, make material try one's best away from the auxiliary section of line shaft and fixed part.But the processing capacity of such process equipment receives the capacity limitation of cup, can not realize continuous charging processing, uses very inconvenient.

Summary of the invention

It is more simple and reliable and can not pollute the fiberizer of foods to be processed that the purpose of the utility model provides a kind of sealing.

For realizing above-mentioned purpose; The utility model has adopted following technical scheme: a kind of fiberizer, comprise the workpiece polishing mechanism and the charging and discharging mouth that is connected workpiece polishing mechanism of the material of polishing, and workpiece polishing mechanism is by motor-driven; It is characterized in that: the line shaft of described motor is connected with the rotary part of workpiece polishing mechanism; Fix a case on the rotary part or on the line shaft, a cylindrical shell is set, described case, cylindrical shell and line shaft coaxial arrangement on the fixed part of all sides of line shaft; Case and cylindrical shell constitute matched in clearance, its gap in the length of 0.1-1.1 millimeter, gap section more than 8 millimeters; Only be communicated with gap between the cylindrical shell between the zone of rotary part processing materials and the line shaft by case.

The beneficial effect of the utility model is: after adopting said structure, the slight gap of case and cylindrical shell can play the possibility that intercepts material and line shaft motion, just plays the effect of sealing; Its principle is exactly; Driving material in the process of rotary part rotation moves around line shaft; The inevitable linear velocity of its line of motion speed greater than the air motion in case and the cylindrical shell, according to hydromechanical principle, the fluid pressure that linear velocity is big is little; So the gas pressure distribution to all sides of rotary part between case and the cylindrical shell is exactly descending, material also just can't get into the high-pressure area naturally.Certainly, because common equipment size and motor speed are limited, it is limited causing draught head, so the length and width parameter in gap again must be within the size of regulation.

Case can not contact or rub with cylindrical shell like this, does not produce so do not have the chip or the dust of wearing and tearing, can not pollute the food of being processed.Such hermetically-sealed construction is simple and reliable, also can not pollute foods to be processed simultaneously, in food processing machinery, has purposes widely.

The specific embodiment

A kind of fiberizer as shown in Figure 1; The workpiece polishing mechanism and the charging and discharging mouth that is connected workpiece polishing mechanism 20,32 that comprise the material of polishing; Workpiece polishing mechanism plays the effect that food is pulverized; Its structure can be the structure of rotation of blade comminuting matter, also can be the structure or the like of the abrasive disc ground material of two relative motions; Workpiece polishing mechanism is driven by motor 8, and just the moving component of workpiece polishing mechanism is driven by motor 8.The line shaft 9 of the described motor 8 just power output shaft of motor 8 is connected with the rotary part of workpiece polishing mechanism, and rotary part just blade or abrasive disc etc. is used for the parts with the food pulverizing.

Fixing case 13 is provided with a cylindrical shell 28 on the fixed part of line shaft 9 all sides on the rotary part or on the line shaft 9, described case 13, cylindrical shell 28 and line shaft 9 coaxial arrangement.Just case 13 is fixed between the end or rotary part and motor 8 of rotary part near motor 8.In conjunction with shown in Fig. 1 to 9, case 13 is fixed on the movable grinding disc 14 end near motor 8; Perhaps also can be arranged on the line shaft 9 between case 13 and the motor 8; Perhaps case 13 only is a cylindrical shell or body, and the surface of movable grinding disc 14 and cylindrical shell or body constitute case 13.The workpiece polishing mechanism of the utility model is positioned at the loading head 18 shown in Fig. 4 to 9, and cylindrical shell 28 correspondingly just is arranged on the position near line shaft 9 of loading head 18 so.Cylindrical shell 28 external diameters are less than the external diameter of case 13, constitute case 13 and constitute matched in clearance with cylindrical shell 28, its gap length in the length of 0.1-1.1 millimeter, gap section more than 8 millimeters; Only be communicated with gap between the cylindrical shell 28 between the zone of rotary part processing materials and the line shaft 9 by case 13; Because loading head of the utility model 18 and cylindrical shell 28 whole machine-shapings; Case 13 is bonded in movable grinding disc 14 lower ends again then; So it is visible like Fig. 1; Line shaft 9 and the zone between the cylindrical shell 28 must have only case 13 to be communicated with gap between the cylindrical shell 28 to lead to around the rotary part, just between loading head 18 and the rotary part.

If the structure of loading head 18 is different with the utility model; Guarantee that then the zone of line shaft 9 all sides and the regional isolated structure of rotary part processing materials also have a lot; Because the situation that itself does not exist moving component to match with fixed part, so be provided with also very simple.

The architectural feature of the utility model is exactly to focus on the gap between case 13 and the cylindrical shell 28 to the seal between the sound parts of line shaft 9 and polishing machining area, and two parts that constitute the gap are connected with fixture with moving part respectively.And this gap, sealing is played in the higher-pressure region that when equipment is worked, forms, and just isolates the effect of line shaft 9 and material, and has avoided the friction between parts, has both avoided wear debris, dust to produce and contaminated food products; Also need not to change seal, save equipment cost, use also more convenient.

Further, the radial dimension of described case 13 is less than the rotating diameter of rotary part.That is to say the diameter of the radial dimension of case 13 less than rotary part rotation institute region covered; Because the utility model utilizes rotary part to drive material rotation generation low pressure and realizes sealing; So case 13 is more little; The rotating diameter of rotary part is big more, and then the linear differential of motion is big more, and sealing effectiveness is good more.In fact the utility model is exactly the range of movement of the scope that rotation covered of movable grinding disc 14 and material scraper 27 integral body greater than case 13.Specifically: it is isometrical with movable grinding disc 14 that the utility model is actually case 13; But case 13 outsides also are provided with like Fig. 2, the material scraper 27 shown in 3; In fact material scraper 27 is processed with case 13 integral body; Riser that axially are provided with along line shaft 9 are divided into two leg-of-mutton plate bodys 271,273 up and down by the level board 272 of direction of motion rear side setting; The triangular plate 273 of bottom coincide with loading head 18 interior shapes like this, is convenient to scrape material, and level board 272 plays the structure booster action as floor simultaneously.The marginal position of loading head 18 is told somebody what one's real intentions are, and yes is convenient to slurry by discharging opening 32 outflows.

Further, the spacing of described cylindrical shell 28 and case 13 is less near line shaft 9 one sides, bigger near food processing zone one side, and the spacing 0.2-0.7 millimeter of smaller portions, length are more than 8 millimeters; Major part spacing 0.4-1.0 millimeter, length are more than 6 millimeters.Like Fig. 1 narrower, bottom broad in top in gap just, air pressure can distribute more equably like this, avoids air pressure step or low pressure to occur in the part, avoids the situation that the material local accumulation occurs or bleed line shaft 9.Certainly, visible by above-mentioned principle, the apparent surface's of cylindrical shell 28 and case 13 radial dimension all is the shape that an end is big, an end is little like this, and less near line shaft 9 one sides, and upside just as shown in Figure 1 is little, downside is big.

Be more preferably: 0.15-0.2 ° of the outer surface of described cylindrical shell 28 and vertical direction deviation, the part surface that part surface that described case 13 and cylindrical shell 28 spacings are less and 0.15-0.2 ° of vertical direction deviation, spacing are bigger and the deviation of vertical direction are at 1.2-1.8 °.Vertical direction is shown in the dotted line among Fig. 2,4.That is to say that cylindrical shell 28 is not straight tube, outer surface is set to frustum at least, and up-small and down-big in Fig. 1, and just outer surface and vertical direction have 0.15-0.2 ° angle.And the inclination situation on case 13 tops is consistent with cylindrical shell 28; But the bottom can be regarded bell-mouthed shape as; Bigger with the deviation of vertical direction; But guarantee the maximum position of gap size just gap spacing dimension bottom still meet the requirement of aforesaid 0.4-1.0 millimeter, guarantee that further sealing is reliable.

Further, the zone between described cylindrical shell 28, case 13 and the motor housing 10 is removed case 13 and is had the gap with 28 of cylindrical shells, and remainder seals.Just as shown in Figure 1, the cavity between line shaft 9 and cylindrical shell 28, the loading head 18 has the gap except

case

13 and 28 of cylindrical shells, the remainder sealing.Such structure is provided with a variety of modes and is easy to realize.For example among Fig. 1; Loading head 18 is connected with screwed hole 37 on the motor housing 10 through connecting hole 182 and screw 36, gasket seal etc.; Between motor housing 10 and the line shaft 9 because itself just contact with foods to be processed, so can use existing mechanical to seal.The advantage of doing like this is: after the cavity of line shaft 9 all sides all seals except the gap between case 13 and the cylindrical shell 28; If materials such as soya-bean milk flow in the gap; Gas in inevitable compression power axle 9 surrounding housings, and this air pressure just can guarantee fully to intercept the entering of material.

Such two kinds of sealing effectiveness mutual superposition play the dual-seal guarantee, reliable effect, and also can reduce the machining accuracy of case 13, cylindrical shell 28 etc.

Visible by above-mentioned principle, a kind of simple hermetically-sealed construction is: the zone between described cylindrical shell 28, case 13 and the motor housing 10 is removed case 13 and is had the gap with 28 of cylindrical shells, and remainder seals; The gap of cylindrical shell 28 and case 13 in 0.2-0.9 millimeter, length more than 10 millimeters.Through verification experimental verification, because the sealing intracavity gas around the line shaft 9 is difficult to compressed reason, can not guarantee that sealing is reliable in this structure so do not have under the situation that tapering, gap size are also big, rotating speed of motor is lower at case 13 and cylindrical shell 28 yet.

Further, described motor 8 is positioned at the fiberizer bottom, and described rotary part is a movable grinding disc 14, and described case 13 is positioned at movable grinding disc 14 downsides and is provided with down; The fixed millstone 17 that cooperates with movable grinding disc 14 is fixedly installed on movable grinding disc 14 tops, 14, the 17 coaxial settings of two mills.Motor is positioned at the bottom of complete machine like this, and machine gravity is lower, and stable equipment operation property is good.And the fineness that the fineness ratio blade of mill relative motion wearing and tearing material is pulverized is higher, more even.

Improvement further; Just adopt the structure that preferably is provided with of mill to be: like Fig. 1; Described fixed millstone 17 is affixed with the feed hopper 21 on complete machine top, and described charging aperture 20 comprises the charging hole that the centre position of fixed millstone 17 is provided with, and charging hole docks with the discharge opening of feed hopper 21; Described line shaft 9 upper ends connect transition disc 26; Between transition disc 26 and the movable grinding disc 14 alignment pin is set; Transition disc 26 upper ends are provided with screwed hole, and described pulverizing screw 16 and screwed hole are spirally connected movable grinding disc 14 companies of wearing and are pressed on and constitute coaxial rotation on the transition disc 26 and be connected; The nut upper surface of pulverizing screw 16 is provided with fin 16`, and it is identical with the position of charging aperture 20 to pulverize screw 16.Like Fig. 1,2, shown in 3, transition disc 26 and line shaft 9 are affixed or be in transmission connection, and pin-and-hole 132 is set on the case 13, and alignment pin is connected in the pin-and-hole 142 on pin-and-hole 132 and the movable grinding disc 14, like this movable grinding disc just can with line shaft 9 coaxial rotation.The concrete structure of pulverizing screw 16 is provided with counterbore 141 like Figure 10, shown in 11 in the middle of the movable grinding disc 14, the screwed hole that pulverizing screw 16 passes on this counterbore 141 and copper backing 15 and the transition disc 26 is spirally connected.Pulverizing screw 16 compresses movable grinding disc 14 so on the one hand, and it is more steady to make that movable grinding disc 14 rotates; Fin 16` simultaneously can be similar to blade when rotated and equally smash the large scale material, plays preliminary pulverization, and such fiberizer can also be used to press sugar-cane juice or the large scale material of polishing.Certainly, for the ease of pulverizing screw 16 stability of rotation, preferably fin 16` is symmetrical set two or more about the center of pulverizing screw 16.

The utility model has further improved the structure of mill.Shown in Figure 12 to 15, equably along the circumferential groove 14` that is provided with, groove 14` is streamlined in the direction of rotation of movable grinding disc 14 on the described movable grinding disc 14; The card middle part of described fixed millstone 17 has the recess of hammer platform shape, and recess surface is provided with many linear grooves 17`, and linear grooves 17` is the setting of center divergent shape with charging aperture 20, the place ahead of oblique movable grinding disc 14 direction of rotation of the flute length direction of every linear grooves 17`; Described charging aperture 20 partly communicates with the large scale of linear grooves 17` and groove 14`.

Also can be regarded as specifically: fixed millstone 17 is screwed onto feed hopper 21 bottoms through connecting hole 171, and the charging hole in the middle of discharge opening in the middle of the feed hopper 21 and the fixed millstone 17 all constitutes the part of charging aperture 20.The tapered end 25 that the lower edge setting of feed hopper 21 can be locked or unclamp, and feed hopper 21 lower limbs have to the centre and stretch out and the buckle 19 corresponding with the flange in loading head 18 outsides 181.19 pairs of the buckles of feed hopper 21 are as three positions on Fig. 7,8, the loading head 18 shown in 9 like this; Rotate the tapered end 25 of screwing after the suitable angle then; Just can realize being connected of feed hopper 21 and loading head 18; And the O-ring seals 24 guarantor junctions sealing that the position corresponding with loading head 18 upper ends is provided with on the feed hopper 21 is reliable, can not leak material.

During fiberizer work; For example material such as soybean is got into by charging aperture 20, is pulverized screw 16 then and tentatively pulverizes, gets into the interior large scale position of groove 14`; Movable grinding disc 14 counter clockwise direction is as shown in Figure 12 rotated then; Material in the groove 14` just constantly is extruded, grinds so, is flowed out by two mill edges along linear grooves 17`, and other has few partial material in the middle of linear grooves 17` gets back to mill, to repeat polishing; Thinner material can strengthen the whole flowability of material, has improved the efficient of polishing greatly.

The outstanding innovation of the utility model is that also the card middle part of fixed millstone 17 has the recess of hammer platform shape, and recess surface is provided with many linear grooves 17`, and such recess is convenient to material and is evenly disperseed, and what utilize accumulation simultaneously is mutual extrusion, wearing and tearing.Simultaneously; Recess is provided with linear grooves 17`, and just linear grooves 17` is not the edge that always extends to fixed millstone 17, but shown in figure 14; Separation disc face edge, recess edge has a segment distance; Linear grooves 17` edge also leaves with the card edge mutually, is like this to utilize the large-area mutual extrusion in card edge, friction, guarantees the fineness of polishing.
