Abstract

The utility model relates to sugarcane press rollers. The inner parts of the roller shell bodies of three rollers are provided with a plurality of juice discharge channels (3) distributed along the circumference. The slot bottom part of the V-shaped circumferential slot of each roller is provided with juice inlet holes (2) whose number is the same as the juice discharge channels. The juice inlet holes (2) are communicated with the juice discharge channels. The intersection angles of the radial line of the minimum wall thickness B and the center lines of the juice inlet holes of each set respectively are 32 DEG to 75 DEG. The press machine adopting the rollers can press more sugarcane juice and the blockage of the juice inlet holes caused by broken sugarcane dregs is greatly reduced. The extraction rate of the sugarcane juice is improved. The yield is increased. The energy consumption is reduced and the work is stable and continuous.

Description

Cane pressing roller of sugar

The utility model belongs to cane sugar manufacture and squeezes the juice with the press for extracting juice roller field of crusher.

Because the working condition of the machinery of squeezing the juice in the cane sugar factory directly has influence on every production and technical indication in sugar refinery, so the existing now technology of much being devoted to improve the crusher working condition.For example at Chinese patent＜efficient cane milling top roller〉(ZL95228522) in, juice groove under the top roller roll surface of press for extracting juice roller is designed to the cross section is length * height=50～200mm * 30～110mm, the juice inlet quantity that flows into every juice groove between per two circle grooves is 3～20, and the aperture is Φ 4～7mm.This press for extracting juice roller has strengthened the juice groove capacity, has increased the quantity of juice inlet, the expressed sugarcane juice can more smooth, more be entered in the juice groove and from the two ends of roller flow out, and has both improved the sugarcane juice recovery rate, has also saved power consumption.But only improve top roller and before and after not touching the structure of two rollers make the machinery of squeezing the juice also have potentiality to dig, and the improvement of top roller also can have other better scheme, in the hope of also reduce the blocked of juice inlet when strengthening juice production as far as possible.

The purpose of this utility model provides a kind of press for extracting juice roller that can increase substantially crusher row juice total volume, increase press for extracting juice roller intensity and be easy to process, reduce the juice inlet obstruction.

The utility model is realized its purpose as follows: in the roller housing of top roller 1, back roller 4, preliminary roller 5, all have some along the circumferential direction distribute, parallel with roll shaft and connect the juice groove 3 of full roller shell, the V-arrangement circumferential slot trench bottom of each roll surface all has the juice inlet of counting on the same group mutually with the juice groove number 2 to be communicated with juice groove, the angle of cut of the radial slit of each centerline hole and minimum wall thickness (MINI W.) B is respectively 32 °～75 ° in every group of juice inlet, towards the same oblique fan-shaped distribution that is.The number of juice inlet can be 2～8, and the aperture is Φ 4～10mm.The bar number of juice groove can be the 6-160 bar, and when being circular as the cross-sectional shape of ditch, the aperture can be 20～80mm.The minimum wall thickness (MINI W.) B of the V-arrangement circumferential slot bottom land on juice groove wall and roller surface can be 10～45mm.

Squeeze the juice with the crusher that the utility model press for extracting juice roller is housed, row's juice is fast, row's juice is many, improved the sugarcane juice sucrose extraction, significantly reduced the latch up phenomenon of bagasse juice inlet, and because bagasse contains sugarcane juice and moisture reduces, reduced the relatively sliding of bagasse and roll surface, help improving the suction sugarcane ability of roll surface, improve daily squeezed quantity, also reduced the crusher energy consumption and prolonged working life.Also, simplified the processing of roller owing to cancelled the circumferential juice ejecting groove of traditional preliminary roller surface V-arrangement circumferential slot bottom land.

Embodiment further specifies the utility model below in conjunction with accompanying drawing:

Fig. 1 is that cross section is arranged in three in the crusher of the present utility model is the shape and the structural representation of the press for extracting juice roller of circular juice groove.Press for extracting juice roller among the figure is the synoptic diagram of transversal profile.

Fig. 2 be the cross section be circular juice groove uniform in a circumferential direction, with three juice inlets partial section that is one group cane pressing roller of sugar.

The top roller 1 of cane mill, preliminary roller 5, back roller 4 are isosceles triangle and are installed on the crusher, have in the roller housing of each roller some along the circumferential direction distribute, parallel with roll shaft and connect the juice groove 3 of full roller shell, the cross section of juice groove can be circular, also can be other shape.V-arrangement circumferential slot bottom land distributes and to be communicated with juice groove with the several on the same group mutually juice inlet 2 of juice groove number on roller shell face, and the angle of cut of each axially bored line in every group of juice inlet and the radial slit of minimum wall thickness (MINI W.) B is respectively 32 ° to 75 °, with the same oblique fan-shaped distribution that is.When beginning to press sugarcane, sugarcane passes through between the top roller 1 of Fig. 1 and front and back roller 5,4, and institute's expressed sugarcane juice flows in the juice grooves through juice inlet 2 from the surface of each roller in traveling process, and flow out at the two ends along juice groove from the roller shell again.Because three rollers are the row's of participating in juice simultaneously, be bordering on comprehensive interior row's juice, the expressed sugarcane juice is discharged easily, sugarcane juice sucrose extraction height not only, be beneficial to and improve sugarcane speed, alleviated roll surface pressure in addition, the crusher pressurized is obviously reduced, reached and improved output, lower energy consumption, obviously improve the purpose of every production technology and financial index.

Press the needs of roller in order to adapt to different sizes, juice groove can be made the 6-160 bar, and every diameter D can be 20-80mm; Juice groove can be that single hole is uniform, also can be that grouping is arranged.Every group of juice inlet can be made of the 2-8 bar, and the aperture d in each hole can be Φ 4-10mm, and the angle of cut of the radial slit of the medullary ray in each hole and minimum wall thickness (MINI W.) B is 32 ° to 75 ° in every group of juice inlet, is fan-shaped array from small to large.The sense of rotation of oblique and roller that top roller, preliminary roller and back roller are respectively organized juice inlet is opposite, because the medullary ray of juice inlet and the radial slit angle of cut of minimum wall thickness (MINI W.) B are apparently higher than traditional press for extracting juice roller, therefore greatly reduce the obstruction probability of broken bagasse, make crusher steady running for a long time juice inlet.In order to guarantee the intensity of roller, the minor increment B with the juice groove wall at the bottom of the roll surface V-shaped groove can be 10-45mm.
