First embodiment
Fig. 1 is refer to, the present embodiment provides a kind of pressing device 100, applied to oil expression, including base 11, squeezing bar assembly
12 and multiple pads group 13.
In the present embodiment, base 11 is frustum cone structure, has certain thickness, plays a part of support；Squeeze bar assembly
12 are arranged at base 11, and with 11 mobilizable connection of base, squeezing bar assembly 12 includes more squeezing bars 121, more squeeze bars 121 around
The center line of base 11 surrounds oil expression chamber 122, and oil expression chamber 122 has feed end, is easy to oil plant placement and depression bar 17 extracting oil
Slided in chamber 122；The quantity of shim pack 13 is identical with the quantity for squeezing bar 121, makes equivalent to shim pack 13 with squeezing the cooperation of bar 121
Include at least one pad 131 with, each shim pack 13, pad 131 between adjacent two are squeezed bars 121, pad 131 with
Any one is squeezed bar 121 and connected, and adjacent two is formed the gap 123 that fuel feeding circulates between squeezing bar 121, according to pad 131
Thickness, the size in gap 123 can be adjusted, so that oil extraction is smooth.
The concrete structure to all parts of the pressing device 100 and mutual corresponding relation are carried out specifically below
It is bright.
As shown in Fig. 2 base 11 is frustum cone structure, base 11 offers first annular groove 111, and first annular groove 111 encloses
Into the pressure-bearing portion 113 for squeezing oil plant, pressure-bearing portion 113 is frustum cone structure, and first annular groove 111 acts the work accepted and positioned
With.The bottom wall of first annular groove 111 offers the second annular groove 112, and the second annular groove 112 is oil scupper, when pressure head extrudes oil
Material, oil flows into first annular groove 111 from gap 123, subsequently into the second annular groove 112.The side wall of base 11 offers and the
The oil-out 114 that second ring groove 112 connects, the oil stream being easy in the second annular groove 112 go out.
Further, base 11 is circumferentially provided with side plate 115, and side plate 115 is located at the upper surface of base 11, side plate 115
Annular accommodating chamber is surrounded, for preventing dust enters squeezing bar assembly 12 from influenceing oil, the oil for being also prevented from squeezing out passes through base
11 upper surface outflow.
It is pointed out that the planform of base 11 is not limited to frustum cone structure, can also be fang platform, special-shaped platform etc.
Other structures, user can choose according to actual conditions.The groove width of first annular groove 111 is according to the size for squeezing bar 121 come really
Fixed, first annular groove 111, which is used to limit, squeezes the moving radially along first annular groove 111 of bar 121, the groove depth of first annular groove 111
It can be chosen according to the actual conditions of user；The groove width and groove depth of second annular groove 112 can choose diversified forms, user
Different sizes can be chosen according to actual conditions.The size of oil-out 114, position are not construed as limiting, and user can be the bottom of according to
The appropriate oil-out 114 of selection of dimension of seat 11.
Squeeze bar assembly 12 to be plugged in the first annular groove 111 of base 11, user can adjust according to demand squeezes bar group
The position of part 12.As shown in figure 3, squeezing bar assembly 12 includes more squeezing bars 121, squeezing bar 121 is rectangular parallelepiped structure, is easy to processing to make
Make.Fig. 4 is the first visual angle sectional view (along the sectional view for squeezing the radial direction of bar assembly 12) for squeezing bar assembly 12, as shown in figure 4, more squeezinges
Bar 121 is distributed around the circumference (equivalent to center line of base 11) of first annular groove 111, and surrounds oil expression chamber 122, and extract oil chamber
122 one end is closed by base 11, another end opening for the chamber 122 that extracts oil.
Extract oil chamber 122 volume by first annular groove 111 size (equivalent to the diameter in pressure-bearing portion 113) and squeeze bar
121 length determines that the volume of oil expression chamber 122 determines the capacity of squeezing oil plant.More are squeezed bar 121 and surround first annular groove
111 it is circumferentially distributed, adjacent two are squeezed bars 121 and contacted, and more are squeezed the oil expression chamber 122 that bars 121 surround and level off to cylindrical cavity, are
Readily appreciate, the structure for the chamber 122 that extracts oil is defined as cylinder, the cross section equivalent to oil expression chamber 122 is similar to circle.
