Abstract
The utility model provides a production intermediate's filtration is pressed from both sides can improve filtration efficiency. A production intermediate's filtration is pressed from both sides, includes filter housing, and the filter housing upper end links to each other with the upper end cover through the flange dish, and the filter housing lower extreme passes through the flange dish and links to each other with the connecting seat, even has the feed liquor pipe on the upper end cover, even has the drain pipe on the connecting seat, is equipped with the filter core in the filter housing, and top -down is equipped with at least two -layer filter screen in the filter core, is equipped with the charcoal package on the filter screen of bottom, it reduces gradually to cross the filtration pore aperture on the top -down filter screen. Has set up the multiple -layer filtering net in this application, has still set up the charcoal package, more thorough to the specific filtration resistance of filtrating, filter to press from both sides establish ties use through two, can improve filtration efficiency, and two is filtered and press from both sides also that the separable from uses, whole process scheme not the stopped status can produce medical product.
Description
Technical field
This utility model relates to field of medicine production, is specifically related to the defecator used time prepared by a kind of medicine intermediate.
Background technology
In medicine intermediate production process, it is necessary to through multistep processing such as reactor, extraction equipment, defecator, mixing arrangements, could produce such as medicine intermediates such as cefuroxime acids.Wherein defecator is mainly used in filtering foreign material therein, and existing defecator efficiency can not meet requirement, and needs regular maintenance down, changes filter element, have impact on production operation.
Utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, it is provided that a kind of filtration folder producing medicine intermediate, can improve filter efficiency.
The technical solution of the utility model is achieved in that a kind of filtration folder producing medicine intermediate, including filtrate housing, filtrate housing upper end is connected with upper end cover by ring flange, filtrate housing lower end is connected with being connected seat by ring flange, upper end cover is connected with feed tube, connects and seat is connected with drain pipe, in filtrate housing, be provided with filter element, being provided with at least two-layer filter screen in filter element from top to bottom, the filter screen of bottom is provided with charcoal bag；On filter screen, filtering holes aperture is gradually reduced from top to bottom.
Described filtrate housing is two groups, and the drain pipe in first filtrate housing is connected by the feed tube on intervalve, the pump housing and second drain pipe.
Described upper end cover is provided with exhaust-valve.
Described intervalve is parallel with transparent observing tube, intervalve is also connected with three-way valve.
The application is provided with multiple filtration net, is also provided with charcoal bag, to the specific filtration resistance of filtrate more thoroughly; filter folder series connection by two to use; filter efficiency can be improved, and two filtration folders can also be used separately, and can produce medical product in whole work flow not stopped status.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the premise not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Wherein: 1. connect seat, 2. filtrate housing, 3. upper end cover, 4. exhaust-valve, 5. feed tube, 6. drain pipe, 7. filter element, 8. filter screen, 9. charcoal bag, the 10. pump housing, 11. intervalves, 12. observing tubes, 13. three-way valve.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not paying creative work premise, broadly fall into the scope of this utility model protection.
As shown in Figure 1, a kind of filtration folder producing medicine intermediate, including filtrate housing 2, filtrate housing 2 upper end is connected with upper end cover 3 by ring flange, and filtrate housing 2 lower end is connected with being connected seat 1 by ring flange, and upper end cover 3 is connected with feed tube 5, connect and seat 1 is connected with drain pipe 6, being provided with filter element 7 in filtrate housing 2, be provided with at least two-layer filter screen 8 in filter element 7 from top to bottom, the filter screen of bottom is provided with charcoal bag 9.Preferably, described filter screen 8 is 3～5 layers, and on filter screen 8, filtering holes aperture is gradually reduced from top to bottom.
In the application, filter screen is provided with multilamellar, step by step medicinal liquid can be filtered, when being typically in changing, ratio is the filter screen changing the top one two-layer more frequently, charcoal bag is additionally set on the filter screen of bottom, by the adsorption of charcoal bag 9, more short grained impurity absorption can be fallen so that the liquid impurity content discharged through drain pipe 6 is less.And from top to bottom, the filtering holes aperture of filter screen reduces, and can improve the efficiency filtered, and reduce clogging so that filter more thorough.
Described upper end cover 3 is provided with exhaust-valve 4, and exhaust-valve 4 is for regulating the pressure in filtrate housing 2.
Preferably, described filtrate housing 2 is two groups, and the drain pipe 6 in first filtrate housing is connected with the feed tube in second filtrate housing by intervalve 11, the pump housing 10.So there are two benefits, 1. can realize cascade filtration, and when one of them filters folder needs replacing or maintenance time, it is only necessary to disconnecting two connecting valves filtered between folder, filtration another one need not overhauled is pressed from both sides and is connected on feeding device.So produce and can keep seriality, it is not necessary to shut down.2. two filter screens filtered in folder can arrange different pore size, so can improve filter efficiency, reduces clogging.
Preferably, described intervalve 11 is parallel with transparent observing tube 12, intervalve 11 is also connected with three-way valve 13.The effect of filtration can be observed by observing tube 12, and then judge whether to need to adjust filter screen etc..When needs adjust filter screen time, adjust the trend of three-way valve.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all within spirit of the present utility model and principle, any amendment of making, equivalent replacement, improvement etc., should be included within protection domain of the present utility model.
