High pressure composite roll grinding machine is that two rollers are done relative motion at a slow speed according to the principle design of material bed grinding, and a roller is fixed, and another roller can slide by along continuous straight runs.Material is fed by roll squeezer top and through two roller gaps continuously, gives the movable roll must active force, material pressurized and pulverizing.Granule that breaks and material get between two rollers of bottom at last, and the granularity that is broken into needs after utilizing bottom two action rollers to carry out squeezing for the second time once more to roll, shears is seen off by conveying equipment.The roller that along continuous straight runs slides is an action roller, and its slip and the clearance distance of keeping between two roll bodies need be able to guarantee that the hydraulic system of its operate as normal realizes.
Summary of the invention
The utility model discloses a kind of hydraulic system of disintegrating machine action roller according to the deficiency of existing disintegrating machine action roller designing technique.The problem that the utility model will solve provide a kind of new hydraulic system better pair of rollers horizontal slip in orbit power is provided, for roller rolls material pressure is provided, guarantee that disintegrating machine more effectively, normally work.
The utility model is realized through following technical scheme:
Disintegrating machine action roller hydraulic system; Comprise motor and the oil pump that dynamicliquid pressure oil is provided, the hydraulic jack that drives the disintegrating machine action roller; Wherein: said hydraulic jack is parallel with hydraulic accumulator; In the said dynamicliquid pressure oil closed circuit two-position four-way solenoid directional control valve is arranged, said dynamicliquid pressure oil oil return has the two-position three way solenoid directional control valve in the loop.
Said dynamicliquid pressure oil oil return has the superposing type overflow valve in the loop.
Said hydraulic jack is parallel with accumulator.
The hydraulic oil heater of the guaranteed hydraulic working oil temperature of said hydraulic system.
In said hydraulic jack and the two-position four-way solenoid directional control valve link circuit check valve is arranged.
The hydraulic system of above-mentioned disintegrating machine action roller also comprises: fuel tank, electric cabinet, return filter, pressure piping filter, air cleaner, Pressure gauge, superposing type pressure switch etc.
The utility model helpfulness is: the utility model adopts hydraulic system to realize the fragmentation work of disintegrating machine action roller; The hydraulic accumulator of parallel connection has guaranteed the duty that system stability continues in the hydraulic system; The hydraulic oil via design is reasonable; Simple for structure, satisfied the badly needs of working environment of disintegrating machine, hydraulic system is that the horizontal slip of roller provides power; For the roller broken material provides pressure; Can also be effectively to occurring material protection disintegrating machine roller really up to the mark in the broken material.

The specific embodiment
Through the specific embodiment and accompanying drawing the utility model is further specified below.Embodiment is used to explain the utility model, limits the utility model never in any form.
Disintegrating machine action roller hydraulic system; Comprise motor 3 and the oil pump 2 that dynamicliquid pressure oil is provided, the hydraulic jack 8 that drives the disintegrating machine action roller; Hydraulic jack 8 is parallel with hydraulic accumulator 11; In the said dynamicliquid pressure oil closed circuit two-position four-way solenoid directional control valve 6 is arranged, said dynamicliquid pressure oil oil return has two-position three way solenoid directional control valve 13 in the loop.
The oil return of dynamicliquid pressure oil has superposing type overflow valve 15 in the loop.
Hydraulic jack 8 is parallel with accumulator 17.
The hydraulic oil heater 5 of the guaranteed hydraulic working oil temperature of hydraulic system.
In hydraulic jack 8 and two-position four-way solenoid directional control valve 6 link circuits check valve 9 is arranged.
In conjunction with Fig. 1 and Fig. 2.
The operation principle of this disintegrating machine action roller hydraulic system: at first to system pressure oil is provided through motor 3 and oil pump 2, promotes hydraulic jack 8 and stretch out, when pressure was raised to operating pressure, 12 actions of superposing type pressure switch quit work motor 3 and oil pump 2.At this moment system is in packing state, and the pressure dwelling loop that promptly is made up of check valve 9 and accumulator 11 makes in the hydraulic cylinder 8 and keeping operating pressure, thereby gushes the broken work of action roller completion that hydraulic jack 8 promotes.This routine oil pump 2 adopts plunger-type fuel pump.
In shattering process; The back and forth movement that the hydraulic cylinder 8 of promotion action roller does not stop; Lean on accumulator 11 pressurizes to keep work; Hydraulic cylinder is after 8 work a period of times, and when pressure was reduced to minimum operating pressure, superposing type pressure switch 12 moved once more and makes motor 3 and oil pump 2 restart the raising oil pressure to operating pressure.
In shattering process, when raw meal particle size was excessive, hydraulic cylinder 8 was drawn back and is let along with action roller; And keep-up pressure, the pressure oil of discharge then gets into accumulator 1, if get into the bigger metallic foreign body of hardness suddenly; Cause hydraulic cylinder 8 astern speeds too fast; Accumulator 11 can not in time all absorb the hydraulic oil in the hydraulic cylinder 8, and oil pressure will rise rapidly and surpass maximum working pressure, and at this moment superposing type overflow valve 15 is the oil circuit overflow with effect.
Be set with a distribution box in mailbox 14 sides, be convenient to operating personnel's operation; When oil circuit 16 enters into hydraulic jack 8; After oil was full of hydraulic jack 8, oil circuit 16 will be exerted pressure to the piston rod in the hydraulic jack 8, shifts piston rod movement onto; Just piston rod is connected with the bearing block of roller again, so just for promoting the roller motion power is provided; Shifting roller onto when oil circuit 16 moves when arriving a certain value; A knob on the electric cabinet is screwed into the pressurize position, and hydraulic system will pair of rollers be carried out pressurize, and two rollers relatively rotate; Make material cracked; When pressure that material bore during greater than dwell pressure, in the hydraulic system under the effect of two-position four-way solenoid directional control valve 6 superposing type overflow valve 15 will in time act on, let the oil in the hydraulic jack 8 be back in the fuel tank 14.
This example has two working oil path, and the operation principle of two oil circuits is identical.
