Abstract

The utility model relates to a pressure device of a hydraulic oil mill, mainly comprising an oil tank, a motor, a filter, a gear pump, an overflowing valve, a pressure oil cylinder, an H-shaped manual reversing valve, O-shaped manual reversing valve and a plurality of one-way valves; the pressure oil cylinder is formed by connecting a plunger type cylinder and a piston cylinder in series, by adopting different effective acting areas of a plunger and a piston, the rapid pressure increasing is achieved; moreover, according to different coarse oil manufacturing requirements, the pressure oil cylinder not only can adopt a one-way pressure oil cylinder, but also a double-way pressure oil cylinder. The pressure device has the beneficial effects that: the pressure oil cylinder is used for replacing a combined pump system adopted by a Korean rapid hydraulic oil mill, the structure is simple and the manufacturing process requirements are low.

Description

A kind of supercharging device of hydraulic oil press

Technical field

The utility model relates to the oil crops processing equipment, relates in particular to a kind of supercharging device of hydraulic oil press.

Background technology

At present, the fast hydraulic pressure oil press that people often use, mostly be Korea Spro's formula oil press that Korea S manufactures and designs, what the super-pressure of this quick oil press (50MPa) hydraulic system adopted is the sundstrand pump system that gear pump combines with high-pressure plunger pump, though oil expression speed is fast, oil yield is high, and complex structure, precision height, need possess higher technological and manufacturing level, sundstrand pump system manufacturing cost height for China overwhelming majority rural area oil crops processor, is difficult to promote the use of.

The utility model content

The purpose of this utility model is to provide a kind of pressurizing cylinder that utilizes to make hydraulic oil press realize super-pressure (more than the 63Mpa), replace Korea Spro's formula fast hydraulic pressure oil press sundstrand pump system, can reach the effect that Korea Spro's formula fast hydraulic pressure oil press speed is fast, oil yield is high like this, can also reduce cost greatly simultaneously.

For achieving the above object, the utility model adopts following technical scheme:

The supercharging device of a kind of hydraulic oil press described in the utility model, mainly comprise fuel tank, motor, cleaner, gear pump, overflow valve, pressurizing cylinder, H type hand-operated direction valve, O type hand-operated direction valve and some check valves, described pressurizing cylinder is in series by plunger case and piston cylinder, utilize the effective active area of piston and plunger different, reach the purpose of quick supercharging, and can be according to different crushed grain material oil expression requirements, pressurizing cylinder both can adopt unidirectional pressurizing cylinder, also can adopt the bidirectional booster oil cylinder; When low pressure oil entered pressurizing cylinder a chamber, piston and plunger were up, because the effective active area of piston and plunger is different, and plunger case output hydraulic oil, supercharging in the oil press oil cylinder is to reach the purpose of quick supercharging.

The beneficial effects of the utility model are: the sundstrand pump system that uses pressurizing cylinder to replace Korea Spro's formula fast hydraulic pressure oil press to be adopted, and simple in structure, manufacture process requirement is low, low cost of manufacture, used power is little, and speed is fast, oil yield is high, can satisfy the requirement of vast rural consumer.

The specific embodiment

As shown in Figure 1, the supercharging device of a kind of hydraulic oil press described in the utility model, mainly comprise fuel tank 13, motor 14, cleaner 12, gear pump 11, overflow valve 10, pressurizing cylinder 1, H type hand-operated direction valve 6, O type hand-operated direction valve 7 and high pressure check valve 2, high pressure check valve 3, some check valves such as check valve 9, described pressurizing cylinder 1 is in series by plunger case and piston cylinder, utilize the effective active area of piston and plunger different, reach the purpose of quick supercharging, and can be according to different crushed grain material oil expression requirements, the pressurizing cylinder 1 of design different size, both can adopt unidirectional pressurizing cylinder, also can adopt the bidirectional booster oil cylinder, required drive is low, and 2.2KW is following to get final product; The pressure height can reach more than the 63Mpa.

When beginning to extract oil, the handle of H type hand-operated direction valve 6 is put to pressurizing cylinder 1 descent of piston position, the handle of O type hand-operated direction valve 7 is put to the centre position, behind the starter motor 14, hydraulic oil is via gear pump 11, overflow valve 10, H type hand-operated direction valve 6, enter the epicoele of oil cylinder 4 by hydraulic control one-way valve 5, this moment, oil cylinder 4 internal pressures reached as high as 20Mpa; Again the handle of O type hand-operated direction valve 7 is put epicoele fuel feeding position to pressurizing cylinder 1, hydraulic oil is through b, the c chamber fuel feeding of O type hand-operated direction valve 7 to pressurizing cylinder 1, then the handle of O type hand-operated direction valve 7 is put cavity of resorption fuel feeding position to pressurizing cylinder 1, hydraulic oil pressurizes to a chamber of pressurizing cylinder 1 fuel feeding through check valve 9, this moment, high-pressure and hydraulic oil was carried in pressurizing cylinder 1 beginning in oil cylinder 4, carried out oil expression work; Behind the oil expression end-of-job, disable motor 14 is put cavity of resorption fuel feeding position to oil cylinder 4 with the handle of H type hand-operated direction valve 6, opens hydraulic control one-way valve 5 and lays down super-pressure in the oil cylinder 4, the handle of H type hand-operated direction valve 6 is put to the centre position again; Oil cylinder 4 continues release, at last the handle of H type hand-operated direction valve 6 is put to the piston stroking upward position, and piston stroking upward prepares to enter next working procedure.
