Description

A kind of for the negative pressure fine filter in pigment production
Technical field
The utility model relates to a kind of for the negative pressure fine filter in pigment production, is a kind of filtration consersion unit.
Background technology
Prior art is used for liquid reaction material (mainly diazol) in the negative pressure fine filter in pigment production and high-purity can not filters and refine and affect pigment quality, existing minifilters (small-sized filter press) not only cleans difficulty, complicated operation, and can not produce negative pressure and make some need the material being decomposed into gas effectively to remove.Therefore, need to provide one to solve the problems of the technologies described above, good filtration effect, refining sufficient efficient stirring blade.
Utility model content
The utility model object is to provide one to solve the above-mentioned problems in the prior art, good filtration effect, refining fully for the negative pressure fine filter in pigment production.
The utility model object is achieved through the following technical solutions:
A kind of for the negative pressure fine filter in pigment production, the filter kettle comprising coupling reaction still and refine for negative pressure, be connected by bottom valve between coupling reaction still with filter kettle, it is characterized in that, also comprise display channel, porous carrying dividing plate, negative tube, vavuum pump and screen pack, the sidewall of filter kettle is provided with display channel, and display channel bottom connects filter autoclave body bottom, display channel top connects negative tube, and vavuum pump is connected with filter kettle by negative tube; The top of filter kettle is porous carrying dividing plate, lays screen pack above porous carrying dividing plate.
As preferably, described negative tube is inclined upwardly 15 degree of angles.
As preferably, also include the input port being filtered liquid, the input port being filtered liquid is positioned at the top of the screen pack of filter kettle.
As preferably, also include negative pressure gauge, negative pressure gauge has been installed in the middle part of negative tube.
Compared with prior art, this product has the following advantages: simple to operate, filters thoroughly, and fully refining, scientific structure design is reasonable, uses reliable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Label declaration: coupling reaction still 1, filter kettle 2, display channel 3, porous carrying dividing plate 4, negative tube 5, vavuum pump 6, screen pack 7, the input port 8 being filtered liquid, negative pressure gauge 9, bottom valve 10.
Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is described, the following example, only for illustration of the technical solution of the utility model, does not limit protection domain of the present utility model.
Embodiment:
As shown in Figure 1, the product of the present embodiment comprises coupling reaction still 1 and for the refining filter kettle 2 of negative pressure, be connected by bottom valve 10 between coupling reaction still 1 with filter kettle 2, the present embodiment also comprises display channel 3, porous carrying dividing plate 4, negative tube 5, vavuum pump 6 and screen pack 7, the sidewall of filter kettle 2 is provided with display channel 3, display channel 3 bottom connects bottom filter kettle 2, display channel 3 top connects negative tube 5, vavuum pump 6 is connected with filter kettle 2 by negative tube 5, and negative tube 5 is inclined upwardly 15 degree of angles; The top of filter kettle 2 is porous carrying dividing plates 4, the screen pack 7 of laying above of porous carrying dividing plate 4.
The present embodiment also includes the input port 8 and negative pressure gauge 9 that are filtered liquid, and the input port 8 being filtered liquid is positioned at the top of the screen pack 7 of filter kettle 2, has installed negative pressure gauge 9 in the middle part of negative tube 5.
Before bringing into use work, first screen pack 7 is laid on porous carrying dividing plate 4, then vavuum pump 6 is opened, input port 8 subsequently by being filtered liquid adds and is filtered liquid, negative pressure gauge 9 shows work negative pressure, display channel 3 display is filtered aqueous condition, and the nitrous acid be filtered in liquid (diazol) decomposes rapidly under negative pressure and removes; Withdraw from screen pack 7 after filtration to clean, negative tube 5 is inclined upwardly and can prevents being filtered liquid under negative pressure and flowed out by this pipe.
By this product, the reaction mass (diazol) of liquid state is directly put into negative pressure fine filter kettle 2, the negative pressure produced in filter again makes the unstable component (nitrous acid) being easy to again to decompose in material fully decompose and be removed, diazol must well be refined, thus synthesize the pigment product of high-quality, the screen pack 7 that more double negative pressure fine filter uses is laid immediately on the porous carrying dividing plate 4 of filter, very easily remove or change, simple to operate, convenient and practical.
Above content described in this description is only to the explanation of the utility model structure example.The novel described those skilled in the art of this use can do various amendment or supplement or adopt similar mode to replace to described instantiation; only otherwise depart from structure of the present utility model or surmount this scope as defined in the claims, all should be belonged to this and use novel protection domain.
