Embodiment
Preferred embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings, so that the advantages of the utility model
It can be easier to be understood by the person skilled in the art with feature, it is apparent bright so as to be made to the scope of protection of the utility model
True defines.The right side of paper, left side in Fig. 1 are corresponded respectively to before and after being addressed in the utility model.
The present embodiment provides a kind of dichloromethane extraction equipment of wet method barrier film manufacture, and it is used for barrier film Central Plains work stone
Wax oil extract and on barrier film pore-forming.Shown in reference picture 1, a kind of dichloromethane extraction equipment of wet method barrier film manufacture,
Groove 1 including offering multiple recovery ports 3, the front portion of groove 1 are further opened with extractant entrance 2, and extractant is specially dichloromethane.
Multiple baffle plates 4 are provided with equal intervals from A-P in groove 1.Baffle plate 4 is fixed in groove 1 vertically, and each baffle plate 4 has respectively to be used for
The upper surface 40 overflowed for liquid in groove 1, in addition to upper surface 40, other end faces of each baffle plate 4 and the inwall of groove 1 connect.
The upper surface 40 of the baffle plate 4 of front side is higher than the upper surface 40 of the baffle plate 4 of rear side, in other words, the upper surface of above-mentioned multiple baffle plates 4
40 reduce successively from A-P, form in ladder low after preceding height.
The number of baffle plate 4 is n, and groove 1 is divided into n+1 overflow unit 10.Corresponding in Fig. 1, n=5, then the sky in groove 1
Between by 5 baffle plates 4 be separated into 6 overflow units 10.Being offered on baffle plate 4 allows liquid in groove 1 to be flowed from i-th of overflow unit 10
To the hole of i+1 overflow unit 10, wherein i is the positive integer less than or equal to n-1, that is to say, that is opened on each baffle plate 4
Located at hole.Direction shown in oil slick and debris along each arrow positioned at upper strata is successively from the overflow of upper surface 40 of each baffle plate 4 under
One overflow unit 10, and the dichloromethane extractant positioned at lower floor then flows into next overflow unit 10 by the hole on baffle plate 4.
The recovery port 3 that the bottom of each overflow unit 10 offers respectively.Dichloromethane extraction equipment also includes connecting back
The recovery tube 5 of closing in 3.Dichloromethane extraction equipment include it is multiple be used to connect recovery tube 5 and the branch pipe 6 of each recovery port 3, each
Tapping valve 7 is respectively arranged with pipe 6.
If such as prior art, overall liquid level in groove 1 is all horizontal, and whole liquid level joins together, and area is big, no
But overflow is slow, and the oil slick of extractant upper surface can due to adhesion to act on being internally formed for extraction equipment many quiet
Dead angle only, oil slick and debris are difficult thoroughly to be overflowed to be recovered below.Based on this, dichloromethane extraction of the present utility model
Taking equipment is designed to that the height of baffle plate 4 between several overflow units 10 is different, forms the step of same gradient, such extractant enters
After entering extraction equipment, because the extractant of circulation can only enter first namely liquid level highest overflow unit 10 at first, this
The extractant of sample miscella paraffin oil will be quickly overflow into second, the 3rd ... a to the last overflow
Groove 1, and the paraffin oil and debris of extractant upper surface also due to flow velocity accelerate and thoroughly with extractant overflow to the end
And be finally recycled, so recycling of the Ladder Overflow method to extractant in extraction equipment can improve 300% effect.
In extraction equipment, extractant dichloromethane is after one end of slave unit flows to the other end with extractant at leisure
It is extracted what Recovery and recycle utilized, and the starting paraffin oil extracted is because density ratio extractant dichloromethane is small, is floating
In dichloromethane upper surface, so being to solve extraction to allow the paraffin oil of extractant upper surface to overflow as soon as possible and be recovered
The fundamental way of problem is taken, so flowing to the principle of lower from eminence according to liquid, enters from extractant in equipment and uses rank
Terraced press over system, groove 1 is separated into several overflow units 10, and the upper end of baffle plate 4 forms the different step of height, and according to
The relation of hydrodynamics and flowing velocity, the rate equation of liquid flowing be p+ ρ gh+ (1/2) * ρ v^2=c, p, ρ, v difference in formula
For the pressure of fluid, density and speed；H is plumb height；G is acceleration of gravity；C is constant, in the same situation of p, ρ, v
Under, h is bigger, and fluid velocity is faster, can only be maximum in the finiteness and the finiteness of instrument size in view of extractant usage amount
The raising h of limit improves overflow, and such extractant can overflow to increasingly lower step along first step of highest, and
The paraffin oil on extractant surface also most can thoroughly overflow to last groove 1 a step by a step along step, finally be recovered machine
Recovery, and h considers cost and volume in device fabrication, typically in 7-10mm.Thus, the height of each baffle plate 4 is 7-10m,
And the difference in height of arbitrary neighborhood baffle plate 4 is consistent.
Above-described embodiment is a kind of preferred embodiment only to illustrate technical concepts and features of the present utility model, its mesh
Be to allow person skilled in the art to understand content of the present utility model and implement according to this, can not limit this with this
The protection domain of utility model.All equivalent change or modifications made according to Spirit Essence of the present utility model, should all cover
Within the scope of protection of the utility model.
