Abstract

The invention relates to crusher machinery, and particularly relates to a tooth roller of a single-roller crusher. The tooth roller of the single-roller crusher comprises a roller shaft, a roller sleeve, crushing teeth and teeth, wherein the roller sleeve is fixed on the roller shaft; the crushing teeth are fixed on the outer periphery of the roller sleeve; the teeth are arranged on the end parts of the crushing teeth; the roller shaft comprises a hollow steel tube and a sleeve composed of at least six fixed plates which are tangential with the outer circumference of the steel tube; a through hole is formed between the sleeve and the steel tube; seal plates are arranged between two ends of the through hole and the steel tube; the steel tube corresponding to two ends of the through hole has connecting holes; the through hole and the steel tube are connected through the connecting holes; two ends of the steel tube are both provided with seal covers; the seal cover at one end of the steel tube has a water intake pipeline hole; the water intake pipeline hole is internally provided with a water intake pipeline; clearance between the water intake pipeline and the water intake pipeline hole forms a water drainage hole; the outlet of the water intake pipeline is positioned in the inner side of the other end part of the steel tube. The tooth roller of the single-roller crusher provided by the invention has cooling and temperature reduction functions, and is light in weight, long in service life, low in required accuracy, and saved in cost.

Description

The single roll crusher discaling roll

Technical field

The present invention relates to a kind of crushing mechanism, be specifically related to the discaling roll on a kind of single roll crusher.

Background technology

Single roll crusher roller tooth is the critical component of single roll crusher, and at present single roll crusher roller tooth mainly consists of circular solids steel axle and the crushing teeth that is fixed on the axle periphery, and roller tooth weight is large, the design requirement on machining accuracy is high, and processing charges is high, and the crushing teeth end is rectangular configuration, damaged resistance is large, lot of energy, and in the work engineering, steel axle and crushing teeth be heat-dissipating very easily all, mutability, crushing teeth is short service life, need to often change, and has increased maintenance cost.

Summary of the invention

The present invention is directed to above-mentioned technical problem, a kind of single roll crusher discaling roll is provided, it has the function of cooling, and lightweight, long service life, precision prescribed low, save cost.

For achieving the above object, the technical scheme taked of the present invention is:

A kind of single roll crusher discaling roll, comprise roll shaft, be fixed on the roller shell on roll shaft and be fixed on the crushing teeth on the roller shell periphery and be arranged on the teeth of crushing teeth end, described roll shaft comprises the steel pipe of hollow and at least by six sleeves that form with the tangent fixed head of steel pipe periphery, between sleeve and steel pipe, leave through hole, between the two ends of through hole and steel pipe, be provided with sealing plate, on the steel pipe corresponding with the through hole two ends, be provided with connecting hole, through hole is connected by connecting hole with steel pipe, the steel pipe two ends are provided with capping, in the capping of steel pipe one end, be provided with the inlet channel hole, the inlet channel hole is provided with inlet channel in hole, gap between inlet channel and inlet channel hole forms apopore, the inlet channel outlet is positioned at inboard, steel pipe the other end.

Described sleeve is connected and forms with the tangent fixed head of steel pipe periphery by six.

Described crushing teeth is triangular prism shape.

Described teeth are the Rhizoma Sparganii taper.

Roll shaft of the present invention adopts the steel pipe of hollow, and it is lightweight, in steel pipe, is provided with inlet channel, can water flowing cool, the axle sleeve in the steel pipe outside adopts six sleeves that form with the tangent fixed head of steel pipe periphery, and roller shell is enclosed within outside sleeve, only needs allly in roller shell with the sleeve periphery is corresponding, to get final product, requirement on machining accuracy is low, between through hole two ends and steel pipe, be provided with connecting hole, water cooling not only can, by steel pipe, refluxing, also can reflux by through hole, carry out dual cooling, cooling-down effect is better; Crushing teeth is triangular prism shape, and there is the rib tooth front side, and the crushing teeth cross section vertical with the crushing teeth Rhizoma Sparganii is triangle, and its damaged resistance is little, and teeth are the Rhizoma Sparganii taper, and front side is the rib point, and damaged resistance is little, reduces energy resource consumption, saves cost, long service life.

Fig. 1 is structural representation of the present invention.

Fig. 2 is the A-A profile of Fig. 1.

Fig. 3 is B-B profile in Fig. 2.

Fig. 4 is C-C profile in Fig. 2.

The specific embodiment

The invention will be further described below in conjunction with accompanying drawing.

As Figure 1-Figure 4, a kind of single roll crusher discaling roll, comprise roll shaft, be fixed on the roller shell 11 on roll shaft and be fixed on the crushing teeth 12 on roller shell 11 peripheries and be arranged on the teeth 13 of crushing teeth 12 ends, roll shaft comprises the steel pipe 1 of hollow and at least by six sleeves 2 that form with the tangent fixed head 10 of steel pipe 1 periphery, between sleeve 2 and steel pipe 1, leave through hole 3, between the two ends of through hole 3 and steel pipe 1, be provided with sealing plate 4, on the steel pipe 1 corresponding with through hole 3 two ends, be provided with connecting hole, be designated as respectively connecting hole I 5 and connecting hole II 6, through hole is connected by connecting hole with steel pipe, steel pipe 1 two ends are provided with capping 7, in the capping of steel pipe 1 one ends, be provided with the inlet channel hole, the inlet channel hole is provided with inlet channel 9 in hole, space between inlet channel 9 and inlet channel hole forms delivery port 8, inlet channel 9 outlets are positioned at inboard, steel pipe the other end, sleeve 2 can be comprised of six fixed heads 10, also can be by seven, the fixed heads such as eight or ten 10 form, the preferred sleeve 2 of the present invention is connected and forms with the tangent fixed head 10 of steel pipe periphery by six, crushing teeth 12 is triangular prism shape, the cross section perpendicular with the crushing teeth Rhizoma Sparganii is triangle, than cross section, be that tetragonal tooth is sharp, resistance is little, teeth 13 are the Rhizoma Sparganii taper, the cross section perpendicular with teeth 13 Rhizoma Sparganiis is triangle, the teeth front side is the cone point, teeth are sharper, resistance is little, save the energy.

When the present invention uses, the steel pipe two ends, by bearing block, are arranged on it on single roll crusher, and inlet channel 9 is passed into to cooling water, cooling water enters inboard, steel pipe the other end, a cooling water part is flowed through the steel pipe inboard through delivery port 8 outflows, and a part enters through hole 3 through connecting hole II 6, then flows into the steel pipe inboards through connecting hole I 5, through delivery port 8, flow out, realize the dual-cooled cooling, avoid the discaling roll excess Temperature, guarantee the normal safe operation of discaling roll.
