In the prior art, in patent ZL92227864.4 and the disclosed technology of ZL00246067.X, mention method, but do not have the device of concrete control concentration, just with microscler baffle controls overflow height with major-minor groove and microscler baffle controls liquid level and control coagulating basin solution concentration.Though and the overflow method that patent ZL96215771.6 proposes is reasonable, and can get rid of the denseer body lotion of bottom solvent, but what obviously adopt is that hard tube connects, only can accomplish the liquid level that keeps certain, can't regulate the liquid level of coagulating bath, and not propose the method for clear and definite gageable adjusting coagulating bath concentration.
The utility model content
The purpose of this utility model is to have overcome above-mentioned shortcoming of the prior art, provides that a kind of fluid infusion combines with overflow, simple in structure, easy to adjust, coagulating bath concentration of component keeps stable adjusting hollow-fibre membrane dry-wet spinning dry-spinning path and coagulating bath technology concentration control apparatus easily.
In order to realize above-mentioned purpose, the utility model is regulated the following formation that has of hollow-fibre membrane dry-wet spinning dry-spinning path and coagulating bath technology concentration control apparatus:
This regulates hollow-fibre membrane dry-wet spinning dry-spinning path and coagulating bath technology concentration control apparatus, form by fluid level control system and fluid infusion system, its main feature is, described fluid level control system comprises a coagulating basin, the side of this coagulating basin is provided with an overfall, one end of a flexible pipe is connected with this overfall, the other end is connected with transverse pipe one end of a T type pipe, the other end of the transverse pipe of this T type pipe is connected with another flexible pipe, and the vertical duct of this T type pipe is fixed on the scale plate by a fixture and can vertically moves freely along this scale plate.
The fluid infusion system of this adjusting hollow-fibre membrane dry-wet spinning dry-spinning path and coagulating bath technology concentration control apparatus comprises several metering devices and corresponding several make-up valve, wherein the liquid outlet of each metering device all is connected with corresponding make-up valve one end by a pipeline, and the other end of this each make-up valve all is communicated with a fluid infusion pipeline.
Owing to adopted the adjusting hollow-fibre membrane dry-wet spinning dry-spinning path and the coagulating bath technology concentration control apparatus of this utility model, fluid infusion combines with overflow with control coagulating bath concentration, it is stepless and adjustable continuously to make adjustment process and fluid infusion process to accomplish, not only easy to adjust, and make the coagulating bath component be stabilized in process stipulation concentration easily, simultaneously simple in structure, produce easy to assembly.
Description of drawings
Fig. 1 is each components schematic diagram of the present utility model.
The specific embodiment
In order more to be expressly understood technology contents of the present utility model, describe in detail especially exemplified by following examples.
See also shown in Figure 1, this regulates hollow-fibre membrane dry-wet spinning dry-spinning path and coagulating bath technology concentration control apparatus, form by fluid level control system and fluid infusion system, wherein, described fluid level control system comprises coagulating basin 1, the appropriate location of the side of this coagulating basin 1 is provided with overfall 2, one end of flexible pipe 3 is connected with this overfall 2, the other end of this flexible pipe 31 is connected with an end of the transverse pipe 41 of T type pipe 4, the other end of the transverse pipe 41 of this T type pipe 4 is connected with flexible pipe 32, and the vertical duct 42 of this T type pipe 4 is fixed on the scale plate 5 by fixture 51 and can vertically moves freely along this scale plate 5.
Described fluid infusion system comprises several metering devices 6 and corresponding several make-up valve 7, wherein the liquid outlet 61 of each metering device 6 all is connected by the end of a pipeline 62 with corresponding make-up valve 7, and the other end of this each make-up valve 7 all is communicated with fluid infusion pipeline 8.
The method that is used for regulating hollow-fibre membrane dry-wet spinning dry-spinning path in the native system is not to regulate coagulating basin 1 itself, but outside groove, regulate the height of T type pipe 4, the liquid level of coagulating basin 1 promptly should be consistent with the transverse pipe 41 of T type pipe 4, i.e. the liquid level 9 of coagulating bath among the figure.Through flexible pipe 31, the T type of flowing through pipe 4 and flexible pipe 32 enter down water or recovery system to the body lotion that overflows from overfall 2.Because T type pipe 4 can be along scale plate 5 up-down adjustment, and the liquid level of coagulating basin 1 is identical with the transverse pipe 41 of T type pipe 4, so can be easily the liquid level 9 of coagulating bath is adjusted and is stabilized in the desirable height of researcher, and its whole adjustment process be stepless, continuously adjustable.The vertical duct 42 of T type pipe is for fear of siphonage takes place with tubing equally, simultaneously as the part of regulating the fixed position, fixture 51 is arranged on scale plate 5, with fixing T type pipe 4, this fixture can adopt various fixed structure, after fixing, make T type pipe 4 vertically to move freely, and regulate the liquid level 9 of coagulating bath in the coagulating basin 1 according to the scale on the scale plate 5 along this scale plate 5.
Because various components enter coagulating basin 1 in the feed liquid, the concentration of component of coagulating bath in the coagulating basin 1 is constantly increased, the fluid infusion system of being made up of the metering device 6 and the make-up valve 7 of some accurate controls cooperates with above-mentioned fluid level control system, the speed that enters coagulating bath by the component and the process stipulation of stoste, can be quantitatively in coagulating bath, replenish body lotion, so the stable solidification concentration of component of bathing effectively.Its fluid infusion process is stepless, continuously adjustable.
Therefore, this programme proposition adds that with flexible pipe it is the length of dry-spinning path that the method for T type pipe can easy, effectively, stably be regulated coagulating bath liquid level height, be equipped with gageable fluid infusion system fluid infusion again, be stabilized in the desirable technology concentration of researcher so can control the coagulating bath component effectively.
In this specification, the utility model is described with reference to its certain embodiments.But, still can make various modifications and conversion obviously and not deviate from spirit and scope of the present utility model.Therefore, specification and accompanying drawing are regarded in an illustrative, rather than a restrictive.
