Fat acid, vitamin etc., the extracting process of the current vegetable oil of China have two classes：Hot rolling and cold-press, wherein most plant
Oily manufacturing enterprise uses hot moulding method.Vegetable oil prepared by hot moulding method has strong fragrance, has catered to consumer demand, but heat
Squeezing the conditions such as high temperature, high pressure in technical process can produce to the protein in oil crops, vitamin and unrighted acid
Negative effect, reduces nutritive value.In order to keep the nutritive value of vegetable oil, the quality of vegetable oil is improved, it is necessary to using cold
Technique is squeezed, oil crops is squeezed at a lower temperature, the nutritional ingredient and bioactivity of reservation crop that can be more complete
Composition.
The cold-squeezing of domestic vegetable oil mainly has screw press and hydraulic pressure to squeeze two major classes, screw press be by diameter by
The big helical axis of gradual change is driven by power, but in rotary course with oil plant friction can occur for rotary shaft produce heat
Amount, elevates the temperature, simply relative low temperature.Hydraulic pressure squeezing is oil of the pressure produced by hydraulic system to dress in a reservoir
Material is extruded and takes oil, is cold pressing truly.Hydraulic oil press in the market is individual workship's production mostly,
Its course of work is first to be fed from the top for squeezing cylinder, and then pressure head is descending, and oil plant is extruded in cylinder is squeezed, squeezed
Pressure head is exited afterwards, then lifts squeezing cylinder, and oil cake is extruded from cylinder is squeezed, oil cake is then removed, has moved after oil cake and put down squeezing cylinder, weight
Reassemble the circulation of material-squeezing-cake discharge；In a cycle squeeze cylinder can not be separated with oil press, the interval time squeezed twice compared with
It is long, cause production efficiency relatively low, be not suitable for large-scale industrial production；Meanwhile, after oil press use time is long, liquid
The piston rod of cylinder pressure can spill hydraulic oil with cylinder body contact position, and such as processing can cause vegetable oil to be contaminated not in time.
The content of the invention
In order to which the production efficiency for solving oil press in the prior art is relatively low, be not suitable for large-scale industrial production, and hydraulic pressure
The problem of cylinder leakage force feed Pollution Plant is oily, the detachable cold pressing oil press of cylinder is squeezed the invention provides one kind.

The limit is squeezed, position-limited wheel 181 will not also be urged to travel switch, and also there will be no shutdown action.
Hydraulic system 3 includes super-pressure duplex pump, high-voltage electromagnetic reversal valve, high-low pressure overflow valve, hydraulic control one-way valve, safety
Valve etc., super-pressure duplex pump is made up of super-high-pressure plunger pump and gear hydraulic pump.When oil press is operated, first squeezed in advance,
Squeezing hydraulic cylinder 12 is set to drive platen 13 quickly to move down, the high velocity, low pressure needed for squeezing can be by the big flow in super-pressure duplex pump
The gear hydraulic pump and high-pressure plunger pump of low pressure are realized jointly, and rear oil press has been squeezed in advance and has carried out low speed heavy pressure motion；Precompressed is complete
Cheng Shi, because operating pressure is increased, when operating pressure exceedes the low pressure relief valve set pressure in high-low pressure overflow valve,
High-pressure pump in low-lift pump meeting automatic overflow in super-pressure duplex pump, super-pressure duplex pump works on, and starts pressurization, makes pressure
The piston rod of squeezing hydraulic cylinder 12 is slow and strong pushing is extracted oil.
Squeeze the detachable cold pressing oil press of cylinder the course of work be：Start precompressed：After squeezing cylinder is in place, electric motor starting, electromagnetism
Reversal valve commutates, and super-pressure duplex pump drives high-low pressure hydraulic oil to enter pressing oil epicoele through high-pressure reversing valve, and oil cylinder starts
Work, carries out precompressed.
Squeezing：After precompressed terminates, when pressure rises to set pressure, pumping plant low pressure relief valve（Pressure setting 8MPa）Unload
Lotus, is extracted oil by the high-pressure plunger oil pump feed in super-pressure duplex pump, according to different oil plants, works out corresponding program, is realized and is added
Pressure-shutdown-pressurization-shutdown, so repeatedly, until completing, it is ensured that high oil recovery.
Oil cylinder is retracted：Extract oil after end-of-job, the control reversal valve commutation of electric control system 4, super-pressure duplex pump is exported
Hydraulic oil enters the squeezing cavity of resorption of hydraulic cylinder 12 and opens hydraulic control one-way valve, and the piston rod of squeezing hydraulic cylinder 12 is retracted.
Reset：The piston rod of squeezing hydraulic cylinder 12 is fallen back on after up to point, and reversal valve sends call signal and exhaled automatically to middle position
AGV Plantago minutas are to remove squeezing cylinder, motor stopping.
The preferred embodiments of the present invention are the foregoing is only, as long as realizing the skill of the object of the invention with essentially identical means
Art scheme is belonged within protection scope of the present invention.
