Description

Mill roll

The present invention relates to a kind of be used to squeeze contain for example mill roll of sugarcane of juice thing, be contained in inner juice in order to extrusion.

Common one one be used for squeezing contain the juice thing for example the pressing device of sugarcane include the mill roll that two or more heterogeneous lap connect.The most basic pattern be comprise two rumble formulas of rumble at the bottom of a top rumble and and comprise a top rumble and two at the bottom of three rumble formula pressing devices of rumble.Each mill roll generally comprises a forged steel axle, by the cast iron manufacturing, and becomes cylindric rumble body with one of mode socket such as hot jacket.The annular surface of rumble body evenly is provided with a plurality of ring-type vee-cuts vertically at interval.Apply suitable power wheel drive, top rumble and end rumble are relatively rotated, so sugarcane can be squeezed between feeding top rumble and the end rumble, and the sugarcane juice that inside is contained is squeezed out.End rumble more offers along the bottom of trench of vee-cut and is commonly referred to as " Maxwell groove " (messchaert grooves), and the expressed sugarcane juice can be in these grooves flow into the container that be located at the pressing device below.

The pressing device of this traditional type has inborn disappearance, be exactly a large amount of squeeze the juice inevasible by repertory above the sugarcane layer, can only slowly penetrate sugarcane laminar flow rumble on earth, therefore in the process of squeezing, a large amount of sugarcane juices is arranged because the sugarcane (being bagasse) that had been squeezed absorbs and causes damage, too much the accumulation of sugarcane juice also causes trackslipping between mill roll simultaneously, seriously has influence on squeezing energy and squeezing efficient.

United States Patent (USP) the 7th, 969, disclosed a kind of top rumble design of attempting solving the conventional apparatus shortcoming for No. 802, this rumble comprises a rumble body of being made by steel, annular surface along the rumble body offers a plurality of grooves, and other has a plurality of row's juice road to run through vertically in the rumble body to offer, a plurality of juice hand-holes are arranged again, be opened in the bottom of trench of aforementioned groove, and extend internally from bottom of trench and to communicate with corresponding row's juice road.In when operation, squeeze the juice from the inside row of the being pressed into juice road of juice hand-hole, discharge the rumble body along row's juice road by rumble body two ends again and flow in the sugarcane juice container, like this, just make the amount of the obtaining increase of squeezing the juice.The wall of these juice hand-holes becomes diffusion type towards axis direction, and row's juice road also becomes diffusion type towards the end of rumble body both sides.

This mill roll of making by steel and cast iron relatively under, owing to easy acid etching, wearing and tearing and surface are become smooth by brighten easily, cause trackslipping relatively between the rumble body, so the inclined-plane of each groove must impose spot welding, with increase the surface roughness, thereby reduce wear and trackslip.

United States Patent (USP) the 4th, 391 has been continued to use United States Patent (USP) the 3rd, 969 No. 026, No. 802 principle of operation, but define a kind of manufacturing process of diffusion type juice inlet in more detail.According to this patent, its top rumble comprises a rumble axle, tubular rumble body is installed on the rumble axle, a plurality of vee-cuts of on the annular surface of rumble body, offering, a plurality of row's juice roads of offering that run through vertically in rumble body inside, the receiving hole of the circle that a plurality of bottoms of trench towards vee-cut are drilled with along groove, continuing to be drilled with the less circular hole of diameter again from this circle receiving hole bottom is communicated with corresponding row's juice road, and there be a plurality of outer rims row juice road corresponding to be communicated with receiving hole, and the plunger that a plurality of outer rims size corresponding with receiving hole is arranged is packed in each corresponding receiving hole, fixed with electric welding, simultaneously also with electric welding with vee-cut surface ruined part Repair Welding original state in addition when offering receiving hole, aforementioned each plunger is provided with the opening of rectangularity roughly, its cross-sectional shape is along the circumferential direction to have than length, length vertically is shorter, and this rectangular opening is towards the axis direction of rumble body and become diffusion type.

These designs have been the improvement shapes of the mill roll of traditional type, yet still have many shortcomings.For example these juice inlet is still blocked easily, the offering of its diffusion type juice inlet, and later maintenance and change etc. all quite numerous and diverse.Therefore again because above-mentioned two inventions all need to use a large amount of electric welding, have to give up the cast iron of commonly using and adopt the preferable steel of weldability to make the rumble shell.But because the acidproof and wear resistant of steel is relatively poor, under the erosion of the high acidity of sugarcane juice and corrosion, its surface is subjected to the damage of acid etching and wearing and tearing very big, and the operator must spend considerable time and money the routine maintenance of surperficial electric welding part.

In addition, these two patents all have another common disappearance, in case the juice that is exactly any row on the rumble body entered the mouth by the moment behind squeezing point or the maximum squeeze pressure point, the row of remaining in juice Dao Neishang is not able to do in time to be squeezed the juice and will be come out by the juice reverse refluence that enters the mouth by what discharged both sides, and the bagasse that was squeezed absorbs again.Two rumble formulas and three rumble formula press apparatus in Figure 1A and Figure 1B difference display operation, moment behind juice inlet 2 revolutions the passing through squeezing point X that rumble 1 upper edge circumference in top is offered, the squeeze pressure of sugarcane juice significantly reduces, cause the sugarcane juice of discharging of not being able to do in time as yet in the row's of remaining in juice road 3 still to come out, and the bagasse that is discharged from absorb again by each juice that communicates with this row's juice road 32 reverse refluences that enter the mouth from both sides.In like manner, obviously disclose as Fig. 1 b institute, the pressing device of three rumble formulas also has same disappearance, seriously has influence on their squeezing efficient.

In addition, because the juice of above-mentioned two patents inlet is opened in the bottom of trench of ring-type vee-cut, the width of each juice inlet opening is subjected to the restriction of vee-cut bottom of trench width, the then restriction of the row's of being subjected to juice road diameter of length of juice inlet opening, and therefore the opening total sectional area of juice inlet can't effectively increase.

The present invention is that the applicant is intended to overcome or solves the variety of issue that exists in the prior art as mentioned above.

Main purpose of the present invention provides a kind ofly can offer the bigger juice long-pending mill roll of total opening section that enters the mouth than prior art, can significantly improve its squeezing capacity and efficient.

Secondary objective of the present invention provides a kind of juice inlet and is difficult for blocked mill roll.

A further object of the present invention provides the manufacturing of a kind of suitable employing cast iron, and manufacturing processed is simple, and cost is lower and do not need the mill roll of electric welding.

Another order of the present invention provides and a kind ofly is fit to individually as top rumble, end rumble or provides the top rumble simultaneously and mill roll that end rumble is used.

A further object of the present invention provide a kind of can effectively prevent to squeeze the juice come out by resorbent mill roll by the reverse refluence that enters the mouth of the juice through being connected in row's juice road.

Mill roll of the present invention comprises a rumble body, this rumble body runs through vertically offers a plurality of row's juice road, each arrange the juice road be in the rumble body, circularize arranged evenly, there are a plurality of juice inlets roughly to extend radially outward to rumble body annular surface again by row's juice road, be connected with each row juice road, and reach hoop vertically and keep suitable spacing mutually.Each juice inlet has less length in the direction along the expressate feeding, and along having than length for best perpendicular to the feeding direction.In other words, suppose to be axis direction perpendicular to the rumble body by the feeding direction of expressate, then each juice inlet should have than length along the axis direction of rumble body, and have smaller length along hoop, and each juice inlet is the annular surface that is opened in the rumble body, and minimumly arranges the juice road and be connected with one.

Certainly, these a plurality of juice inlets can be to reach all corresponding arrangement of hoop vertically, or corresponding vertically the arrangement, then are staggered along hoop.The cross section of each juice inlet can be into regular shape or irregularly shaped, and can become diffusion or contraction-like towards rumble body internal direction, or becomes contraction-like in the stage casing, and is into diffusion type towards inside and outside both sides.

Similarly, the cross-sectional shape in row juice road can be multiple different shape, and for example circle, ellipse, rectangle, trapezoidal and/or fan-shaped wherein especially having than length towards axis direction, and are that to become diffusion type towards rumble body annular rim face direction be the best.This row's juice road can adopt the mechanical workout mode or cast with rumble body one.

A plurality of grooves can be offered equally in the surface of rumble body, are the best with the hoop groove of forming V-shape roughly wherein, this groove be by a pair of become towards axis direction in the relative groove face of poly-shape, and the bottom of trench between two groove faces is formed.The part of offering at least one groove face that comprises a bottom of trench and/or at least one groove at least of each juice inlet; Wherein the length of each juice inlet opening is the best with the slot pitch that is approximately equal to several grooves again.

Further, because each juice of the present invention inlet is less along the opening length of hoop, so each row's juice road can communicate with the juice inlet of two or more rows simultaneously, significantly to increase each row's juice number of times in changeing of mill roll.Therefore each juice inlet all can have long length, and total juice inlet effective vent area of whole mill roll can significantly increase, thereby can improve the row's juice capacity and the efficient of mill roll greatly.

The inner end that the vacant body of going into of merely hitting of more can respectively packing into again in each juice inlet of rumble body, this hollow are inserted body protrudes into inner one section predetermined distance in row's juice road of each correspondence, with the formation repertory space of squeezing the juice.In like manner, this rumble body can comprise a tubulose projection equally and protrude out one section predetermined distance by the inboard of each juice inlet towards the inboard, row's juice road of correspondence, forms an ennation and repertory space in row's juice road, comes temporary transient repertory to squeeze the juice.

Another aspect of the present invention, its temporary transient repertory space of squeezing the juice is to make juice inlet and corresponding row's juice road,, cause delay side relative same row's juice road in or leading side and juice to enter the mouth to completely cut off and form according to the leading side of rumble body turning direction or postpone side and communicate in row juice road.

The repertory spatial advantage of squeezing the juice that mode forms as described above is to squeeze the juice, before not being able to do in time to discharge from rumble body both sides, and temporarily in the row's of being rested on juice road, the not reduction of reason squeeze pressure, and the juice that was connected the certainly reverse refluence that enters the mouth is come out.

Because juice inlet of the present invention can be processed by the rumble body easily, therefore production process of the present invention is more simpler than used, and does not need to use electric welding.Again because the rumble body can use cast iron to make, therefore than used comparatively cheap and the more acidproof and abrasion performance of squeeze roll that must use cast steel to make.

In addition, this mill roll can be used existing mill roll, individually as top rumble or end rumble, or cooperates simultaneously as top rumble and the use of end rumble.

Below with reference to the accompanying drawings, preferred embodiment of the present invention is elaborated.

Though following narration relates to a kind of voltage supply and presses the mill roll that sugarcane is used, similarly, the present invention also is suitable for squeezing any juice thing that contains, and squeezes its juice.

As shown in Figure 2, mill roll 10 of the present invention comprises a rumble axle 11, and socket rumble body 12 on the rumble axle 11 runs through vertically in rumble body 12 and offers a plurality of row's juice road 13, and each is arranged juice road 13 and preferably roughly circularizes arranged evenly in rumble body 12.The cross-sectional shape in the row's juice road 13 shown in the figure roughly is to be circle, but the cross section of in fact arranging juice road 13 can become different shapes, for example oval, rectangle and/or fan-shaped are it especially with towards the axis direction tool than length, be good and become diffusion type towards the ring edge of rumble body.But row's juice road 13 mat mechanical workouts are shaped or form with rumble body integrally casting.

The annular surface of rumble body 12 offers a plurality of juice inlet 14 its openings and is located on the annular surface, and each opening axially has than length along the rumble body, and shorter along the length of its hoop.These a plurality of juice inlets 14 reach all roughly rule of correspondence arrangement of hoop vertically.Except corresponded manner was as shown in FIG. arranged, each juice inlet 14 also can be done the arrangement of different modes according to other geometric format.The opening of each juice inlet 14 roughly extends in the rumble body towards axis direction, so that each juice inlet 14 is connected with row's juice road 13 at least.

Fig. 3, Fig. 4 and Fig. 5 show another possible embodiments of the present invention, and wherein rumble body 20 is by an interior rumble body 21, and socket rumble shell 22 cylindraceous in outside is formed.Rumble body 21 offers along the outer circular edge face and a plurality of running through vertically offers and circularize row's juice road 23 arranged evenly in being somebody's turn to do.Rumble shell 22 can be made by multiple unlike material, for example cast iron, steel or cement etc., and stretch along anchor ring at the adjacent groove 24 that annular surface offers a plurality of roughly forming V-shapes, each is made up of two adjacent groove faces 27 and a bottom of trench 26, offer a plurality of juice inlets 25 on the rumble shell 22, the opening of each juice inlet 25 is with along axially the having than length of rumble body, and is short in good along the length of its hoop.These a plurality of juice inlets 25 are corresponding vertically substantially to be arranged, and axially adjacent two rows' juice inlet 25 is then staggered mutually at the hoop of rumble body.In a word, just as embodiment shown in Figure 2, the juice of present embodiment inlet can be done the arrangement of different modes equally according to other geometric format.Offering of juice inlet unlike existing mill roll is to be confined to channel bottom, and inlet 25 openings of each juice of present embodiment are to run through four bottoms of trench 26 and six groove faces 27 continuously.Juice inlet 25 length vertically can be the width less than a vee-cut 24, equal the width of a vee-cut 24, or greater than the width of a vee-cut 24, even can reach the width of a plurality of vee-cuts 24, be good especially with slot pitch width greater than single groove 24; Simultaneously, the cross-sectional shape of juice inlet 25 can be rule or irregular.In the latter, each juice inlet 25 can be into diffusion type or pinching shape towards the inner direction that is connected with row's juice road 23 of rumble body, or being into the pinching shape to the middle part of juice inlet, both sides all become diffusion type and reach outwardly inwardly, respectively shown in Fig. 3 D, Fig. 3 E and Fig. 3 F.The cross-sectional shape in the juice of row shown in figure road 23 is circular substantially.Yet arrange juice road 23 as shown in the figure and can become different shapes, for example oval (shown in Fig. 3 A), rectangle (shown in Fig. 3 B), and/or fan-shaped (shown in Fig. 3 C), especially towards the axis direction tool than length, and towards the annular rim face of the rumble body person that becomes the diffusion type for good.

Be different from prior art mill roll juice inlet width be subject to groove bottom of trench width, and the diameter in the row's juice road that is subject to its connection of length, the mode of offering of juice inlet 14 or 25 of the present invention, allow that passage can have the opening total sectional area bigger than the mill roll of prior art, for collecting and discharging and squeeze the juice.In fact the present invention does not just increase the collection and the discharging of squeezing the juice, and the squeezing efficient of raising mill roll, more can reduce the squeezing the juice of mill roll of prior art greatly, and mill roll may produce and trackslips relatively and reduce the phenomenon of the ability of squeezing the juice by resorbent loss.

Another advantage of the present invention can prevent that exactly juice inlet 14 or 25 is blocked.As shown in Figure 4, juice inlet 25 of the present invention reaches along the long end M of axially having of rumble body and along the circumferential direction has short end N.Since to be squeezed contain the juice thing for example sugarcane etc. be to feed between the mill roll by the direction that is indicated as arrow F, and fiber of sugarcane or bagasse are pressed into the probability in the juice inlet 25, obviously be to be directly proportional in the length of sugarcane travel direction with juice 25 openings that enter the mouth, juice of the present invention inlet 25 is minimum along the length distance of N direction, that is has reduced the juice 25 blocked possibilities that enter the mouth greatly.In addition, the offering of juice inlet that is different from the mill roll of prior art along hoop, so that length is limited by the width or the bore in its corresponding row's juice road, juice of the present invention inlet 25 is offered because of extending axially in rumble body upper edge, and can run through the bottom of trench and the groove face of several grooves continuously, the inside gross space of its juice inlet 25 is big many far beyond existing.Therefore, even just in case have into strips Caulis Sacchari sinensis fiber or bagasse to insert in the juice inlet 25, juice inlet of the present invention has enough roomy inside and moves the space, make the converted top of insertion can be easily along with sugarcane juice is gone out through row's juice road, and enter the mouth unlike the juice that the mill roll of prior art is offered, offer method because of it and make the space be subjected to arresting limit, in case fiber is stuck in the juice inlet, the accumulation because of bagasse causes the juice inlet blocked fully at last.

As shown in Figure 5, each juice inlet 25 preferably comprises a juice entrance extension body 29, this juice entrance extension body 29 is suitable in the row of the entering juice road 23 with one section of tubulose convex body structure extension by the inner end of juice inlet 25, so that 23 inner formation, one juice repertory spaces 30, row's juice road.The convex body of each juice entrance extension body 29 can be to form with row's juice road 23 integrally castings, or adopts other suitable modes to be fixed in row's juice road 23.When juice inlet 25 along with the revolution of rumble body during by the squeezing point between top rumble and end rumble, squeeze pressure moment reduction, be not able to do in time as yet in the row of the residuing in juice road 23 to be able to the juice repertory space 30 of temporary transient repertory in row's juice road 23, continue to emit by rumble body both sides by the sugarcane juice that rumble body both sides give off.Though row's juice road 23 is interconnected with corresponding juice inlet 25, yet, because juice entrance extension body 29 is higher than by the temporary transient liquid level of repertory in same row's juice road 23 with the intersection mouth position in row's juice road 23, the sugarcane juice of repertory in juice repertory space 30 will can not enter the mouth via juice and 25 blow back in the bagasse that was squeezed.Therefore the present invention can avoid over that reverse refluence is come out owing to squeezing the juice usually and by resorbent a large amount of mill losses.

Fig. 6 and Fig. 6 A show that another kind can form the design of juice repertory spatial in row's juice road 23.One is shaped with row juice road 23 integrally castings, or uses electric welding or other suitable technology, and the channel element 28 in the row of the being fixed on juice road 23 is stretched into and arranged juice road 23 interior one section suitable distance by juice 25 internal openings that enter the mouth.This channel element 28 extends to the juice inlet 25 that the other end offers this element 28 and same row vertically continuously by the end in row juice road 23 and communicates, and forms same row's juice road 23 each interior juice enter the mouth 25 common ennations and juice repertory space.

Fig. 7 shows the another kind of design that forms similar juice repertory space 30 in row's juice road 23.Be close to the juice hollow that 25 walls closely are pressed into that enters the mouth with one and insert body 31, its inner end stretches into corresponding row's juice road 23 interior one section suitable distance, just can form one and extend passage also thereby form a juice repertory space 30 in row's juice road 23.This insertion body 31 is to force closely to be press-fitted or to utilize other proper technology means to be fixed in the juice inlet 25, this insertion body can not come off in the press operation process.

Aforementioned formation juice repertory spatial design all can be used for two rumble formulas or three rumble formula pressing devices, uses (consulting Fig. 8 and shown in Figure 14) but be particularly suitable for three rumble formula pressing devices.The cross-sectional shape of above-mentioned juice entrance extension body 29 roughly can be identical with the cross-sectional shape of juice inlet 25, or becomes to enlarge to launch shape, to increase the efficient of juice repertory.

Fig. 9 shows that another forms the design of juice repertory spatial in row's juice road 23 of rumble body 20, is particularly suitable for using for two rumble formula pressing devices.The design adopts each juice inlet 25 to be connected with row's juice road 23 leading side 32 according to rumble body turning direction in row's juice road 23, cause with row's juice road 23 interior delay sides 33 along rumble body turning direction be able to and respectively this juice enter the mouth and 25 be isolated and form juice repertory space 34.The shape that shows row 23 cross sections, juice road among the figure is ovalization substantially, and juice inlet 25 can the leading edge general tangential according to rumble body turning direction be communicated with in row's juice road with row's juice road 23.Yet the cross-sectional shape in row's juice road 23 can be other shapes equally, for example rectangle, ellipse, trapezoidal and/or fan-shaped.As with Fig. 5 and the shown juice repertory space 30 of Fig. 7, can squeeze the juice and continue repertory in row's juice road 23 in this juice repertory space 34, till to the last emitting from 23 ends, row's juice road of rumble body both sides.Usually owing to squeeze the juice that reverse refluence is come out and therefore avoided, and can thereby increase the amount of squeezing the juice by resorbent a large amount of mill losses, and reduce bagasse contain the juice degree.

As shown in figure 10, the inner end of juice inlet 25 also can be connected with the delay side in row's juice road 23 equally, thereby the leading side in this row's juice road 23 forms similar juice repertory space.

Because main-inlet 14 of the present invention or 25 its length along hoop are very little, the juice inlet 14 or 25 that therefore can offer two or more rows very easily vertically communicates with single row's juice road 13 or 23.Therefore, each the row's juice road that is different from the mill roll of prior art can only be provided with a row juice inlet, with regard to the rumble body of row's juice road 13 with similar number or 23, total row's number of juice inlet 14 or 25 of the present invention can increase greatly, when therefore mill roll turns around for every time, there is the juice inlet to improve through the frequency of squeezing point, add the significantly increase of the juice inlet opening total area, make in any unit time institute's amount of obtaining of can an expressed squeezing the juice be able to significant improvement, squeezing efficient is improved, and absorbs and the tradition of trackslipping disappearance all can further overcome again.

The preferred arrangement method of juice inlet rumble body 20 in when Figure 11 and the juice inlet 25 that Figure 12 shows that two rows are connected with single row's juice road 23, the adjacent juice of illustrated two rows 25 hoops along rumble body 20 that enter the mouth are the shape arrangements that become to stagger mutually.Each juice inlet 25 be with offer by the angle of the rumble body 20 axis direction line deflections of this juice inlet 25 and row's juice road 23 joinings respectively.The inner end opening of the juice inlet 25 that these two rows that offer vertically are adjacent all communicates with row's juice road 23 through same juice entrance extension body 35 backs, and this juice entrance extension body 35 is identical with the structure of the channel element 28 shown in Fig. 6.The structure of the juice entrance extension body shown in Fig. 5 and Fig. 7 also is fit to use equally.

In fact and be regardless of and be limited to this though above diagram or be stated as the adjacent juice of offering vertically of two rows inlet 25 and arrange juice road 23 and be connected with same, the present invention.Each row's juice road 23 can communicate with three rows or the above adjacent juice of offering the vertically inlet 25 of three rows equally simultaneously.

Mill roll of the present invention can be separately and the mill roll of other traditional types and usefulness, or use as top rumble and end rumble as Figure 13 and while shown in Figure 14.With each identical parts noted earlier, all indicate among the figure with identical number.Rumble body 20 is used as the top rumble simultaneously and end rumble uses; Rumble both sides, top are installed with flange component 36; In addition, pollute the rumble axle of top rumble and end rumble 20, also respectively be provided with main loop 37 in rumble body 20 both sides in order to prevent sugarcane juice.The groove 24 of top rumble 20 and the groove 24 of end rumble 20 be bridle joint mutually.When one contains the juice thing for example sugarcane is squeezed,, under squeeze pressure greatly, by juice inlet 25 row of the entering juice roads 23 of top rumble and end rumble, discharge by rumble body both sides then respectively by the expressed sugarcane juice.Certainly squeezing the juice of part still can flow in the container of pressing device below along the vee-cut of end device.When using as end rumble, the present invention also can adopt the Maxwell groove of traditional type simultaneously.

Although the present invention be according at present consider that practical and the most best embodiment is narrated, yet the present invention only arrests to be limited to above disclosed embodiment, it should also determine to have contained equivalence and improvement design and the goods that make according to technological thought of the present invention and field, and its territory also should give to assert the most widely so that it comprises any and all improvement of the traditional technology relevant with the present invention and the present invention; For example, but more than that, offer " snow inspires confidence in orchid " (chevron) (Kay) formula groove of formula groove or " triumphant " in the rumble surface.
