Abstract
The utility model relates to a pressure filter belonging to pressure filtration and separating device, which divides one vessel into an upper and a lower part; the emulsion flows into the lower part, passes through a filter cloth and a filter tube, enters the upper part and discharges from the vessel; the filtered emulsion discharges from the vessel by a scraper and achieves separation. The utility model has the advantages of compact structure, big emulsion separation amount, high efficiency and continuous working. The separated calcium carbonate(the white mud)is clean and has a high concentration.
Description
The utility model belongs to the pressure filtration device, relates to a kind of device that from the emulsion that the paper mill causticizer comes out solid carbonic acid calcium (white clay) is separated.
At present, from the emulsion that causticizer comes out with divided calcium carbonate from device mainly contain the white clay clarifier, its operation principle is the effect natural sedimentation by gravity, makes the bigger calcium carbonate of proportion be deposited in the bottom, top is the white liquid of clarification, thereby reaches the purpose of separation.This equipment volume is huge, inefficiency, and the work elastic range is little, and separating effect is not good, and white clay content is higher in the white liquid.
The purpose of this utility model just provides a kind of chimney filter that is provided with in pressure vessel, provide certain pressure, the device that white clay is separated with white liquid.
The solution that realizes the utility model purpose is to comprise that pressure vessel (2), emulsion feed tube (10), white liquid drain pipe (4), white clay go out pipe (14), particularly the top in pressure vessel (2) is provided with the card (3) that is connected with pressure vessel (2), chimney filter (8) is installed on the card (3), and fixing by presser cut (7).
Chimney filter (8) is a tube empty in the middle of, an outward flanging, and one with the flat board sealing, has densely covered aperture on the flat board of the periphery of tube and sealing, and the outer surface of chimney filter (8) is provided with filter cloth (9), and chimney filter (8) has four at least.Card (3) is provided with the hole, and chimney filter (8) is put in this hole, and the flange on the chimney filter (8) is stuck on the card (3), and the hole on the presser cut (7) is corresponding with the hole on the card (3), and is placed on the flange of chimney filter (8), links together with screw (6) and card (3).
The interior presser cut of pressure vessel (2) (7) top is provided with subregion dividing plate (5).
The utility model has the advantages that compact conformation, the separation of emulsions amount is big, efficient height, but basic continuous operation, isolated calcium carbonate (white clay) concentration height is clean.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of chimney filter.
The utility model is described in further detail below in conjunction with accompanying drawing:
Be connected to white liquid drain pipe (4) at pressure vessel (2), the middle part is provided with emulsion inlet pipe (10), between drain pipe (4) and inlet (10), be provided with the card (3) that the inwall with pressure vessel (2) is fixed together, card (3) is provided with the hole, chimney filter (8) is put in this hole, and the flange on the chimney filter (8) is stuck on the card (3), and the hole on the presser cut (7) is corresponding with the hole on the card (3), and be placed on the flange of chimney filter (8), link together with screw (6) and card (3).Chimney filter (8) is a tube empty in the middle of, an outward flanging, and the other end is with dull and stereotyped sealing, has densely covered aperture on the flat board of the periphery of tube and sealing, and the outer surface of chimney filter (8) is provided with filter cloth (9).Chimney filter (8) evenly gathers on card, has four at least.Be provided with in presser cut (7) top and separate plate (5), presser cut (7) upper space is separated into separate several regions.If certain district's chimney filter (8) filter cloth damages, can not influence the overanxious white liquid in other district.Be provided with scraper (12) in the bottom of pressure vessel (2), scraper (12) links to each other with motor (13) by transmission device.Manhole (11) is a maintenance usefulness.Pickle outlet (1) is cleaning pressure container (a 2) usefulness.
Emulsion is entered with certain pressure by emulsion inlet tube (10) during work, white liquid in the emulsion just enters the centre of chimney filter (4) by the filter cloth (9) on the chimney filter (4), arrive the top of presser cut (7), and in the zone that is separated into by demarcation strip (5), discharge from white liquid outlet (4).Emulsion is after filtering after a while, white clay is gone up at filter cloth (9) and is formed filter cake, filter cake is the very high white clay of solid content, can be regularly by the white liquid backwash of cleaning, filter cake on the filter cloth (9) is washed out, drop to the decanting zone by gravity, scraper (12) is equipped with in the decanting zone, can in time white clay be wiped off from the barrel of pressure vessel (2), discharge from white clay outlet (14).
