Abstract

The utility model belongs to a squeezing roller on a sugarcane squeezing machine in sugar factories. A cast iron roller sleeve is sheathed on the outside of a steel shaft in center, an axial juice expelling passage is arranged on the roller sleeve, an alloy steel roller casing is sheathed on the outside of the cast iron roller sleeve, a roller tooth is arranged on the roller casing, the bottom of the roller tooth is provided with a juice entering mouth which is communicated with the juice expelling passage, and abrasion resistant alloy steel is welded on the top of the roller tooth and the side of the roller tooth in a built-up way. The sugarcane squeezing roller is more than twice longer service life than existing squeezing rollers, is improved on squeezing rate, is made of existing scarp squeezing rollers to reuse, causing the production cost of the sugar factory to be reduced.

Description

A kind of Sugar cane press roller

The utility model relates to the press for extracting juice roller on a kind of the cane sugar factory mechanical means, particularly cane mill.

Press for extracting juice roller (comprising top roller and bottom roller) structure on the present being seen cane sugar factory squeezing machine is cast iron roll shell of central steel shaft overcoat, have the roller tooth of herring-bone or splayed or other shape on the roller shell, heavy suction phenomenon for fear of sugarcane juice, manufactured and designed coupling tube roller again from the seventies people, promptly having radial juice inlet at the bottom of the tooth of roller shell or on the flank, having axial flow juice passage in roller tooth bottom.It is the insufficient strength of cast iron roll shell that there is maximum weak point in this Sugar cane press roller, not wear-resisting, easily collapse tooth, the press for extracting juice roller in most of sugar refinery can only use one and press season (4-5 month) just roll change shell more, in order to increase work-ing life, people have taked some measures, as tooth top and flank deposited metal point at the roller tooth, have built-up welding is once again after polishing, but also can only use some months more, finally still unavoidably the cast iron roll shell be changed, make sugar refinery increase equipment loss, improve cost, reduced benefit.

The purpose of this utility model provides a kind of roller shell intensity height, wear-resisting, the high Sugar cane press roller of squeezing efficient, can also be used again having the depleted cast iron roll shell that weares and teares now.

The utility model is realized in following mode: cane pressing roller of sugar comprises central steel shaft and roller shell, be characterized in pressing roller and divide three layers, innermost layer is a central steel shaft, central steel shaft is with the cast iron roll cover outward, this layer cast iron roller shell and existing roller shell are similar, but diameter is slightly little, the cast iron roller shell also is with alloy steel rider shell outward, alloy steel rider shell surface has the roller tooth, and roller tooth bottom has radially juice flow inlet, and this juice flow inlet is from outside to inside being the bellmouth orifice that enlarges gradually, skin at the cast iron roller shell has axial juice discharging channel, this juice discharging channel communicates with loudspeaker juice flow inlet radially, and in order to make alloy roller tooth wear resistance better, built-up welding has wear-resisting alloy steel on tooth top and the flank.

The utility model has the advantages that:

1. it is very high to press the roller wear resistance, be difficult for collapsing tooth, the life-span of pressing roller is prolonged more than 2 times, present cast iron roller shell only can use one to press season, change these three layers and can use 2-3 to press season after pressing rollers, still can keep squeezing ability and sugar part sucrose extraction without roll change shell crusher in promptly 3 years.

2. cost and cast iron roll shell remain basically stable, and the equipment loss rate obviously reduced without the roll change shell in 3 years.

3. the heavy suction phenomenon of sugarcane juice reduces, owing to adopt tubaeform radially juice flow inlet, bagasse is difficult for stopping up juice flow inlet and juice discharging channel, therefore can keep very high sucrose extraction in whole press for extracting juice season.

4. the cast iron roll shell of former wearing and tearing need not abandon, and it is flat only need to get on the bus at lathe, opens axial groove, puts alloy steel rider shell again and promptly can be made into this roller.

5. on roller shell surface, need not open " people " word groove, still maintain enough sugarcane abilities of holding.

Below in conjunction with accompanying drawing enforcement structure of the present utility model is described:

Fig. 1 is the cross sectional representation of three layers of Sugar cane press roller;

Fig. 2 is three layers of axial sectional view of Sugar cane press roller.

See that from figure the Sugar cane press roller innermost layer is a central steel shaft 6, the steel axle is outward a cast iron roller shell 4, have axial juice discharging channel 5 on the roller shell, also be with alloy steel rider shell 3 outside the cast iron roller shell 4, roller shell 3 is provided with roller tooth 1, have at the bottom of the tooth and radially arrange juice mouth 2, wear-resisting alloy steel 8 in tooth top and the flank built-up welding.

Claims

1. a Sugar cane press roller comprises central steel shaft and roller shell, it is characterized in that; Press roller and be divided into three layers, the inside is central steel shaft (6), central steel shaft is with cast iron roll cover (4) outward, the cast iron roller shell 4 outer alloy roller shells (3) that also are with, roller shell surface has roller tooth (1), roller tooth bottom has radially juice flow inlet (2), has some axial juice discharging channels (5) at the outside surface of cast iron roller shell (4), and juice discharging channel (5) radially juice flow inlet (2) communicates.

2. Sugar cane press roller according to claim 1 is characterized in that radially juice flow inlet (2) is the bellmouth orifice from outside to inside enlarging gradually.

3. Sugar cane press roller according to claim 1 is characterized in that the tooth top of roller tooth (1) and flank built-up welding have wear-resisting alloy steel (8).
