Abstract

The utility model discloses a transfusion cylinder type finely filtering device for production which is mainly composed of a cylinder body, a flange chassis, a porous filtering screen, a microporous filtering film, a liquid inlet tube, a liquid outlet tube and an exhaust pipe. The porous filtering screen with the microporous filtering film is in the shape of cylinder; the lower end of the porous filtering screen is fixed on the flange chassis. Therefore, the filtering area is increased, the liquid leakage brought for the broken film and the non-tight seal is avoided, and the medicine liquid is not retained on the inside of a filtering device after the people filter.

Description

Drum finely filtering device

The utility model belongs to filter cartridge type filter technical field.

The fine filtering device that adopts in the infusion solutions production process mostly is the disc type nuclepore membrane filter at present, and it mainly is made up of the porous sieve plate and the loam cake of chassis, band miillpore filter, and it has following deficiency:

1, filter area is little, and filtering velocity is slow;

2, soup directly washes away the filter membrane face, and making can saturating film than small particle and mistake influences the filtrate quality;

3, filter membrane is connected with loam cake with the chassis by packing ring with sieve plate, fixes tightly leakage can not take place;

4, filter membrane tensile strength is low, and the rupture of membranes leakage easily takes place.

The purpose of this utility model is at the deficiencies in the prior art, and a kind of fine filtering device that infusion solutions is produced that is used for is provided, and not only filter area is big to make it, and the rate of filtration is fast, and can improve filter quality.

The utility model is achieved in that cylindrical shell cylindraceous top has feed tube, the cylindrical shell bottom is sealed by the flange chassis, tubular porous filter screen lower end is fixed on the flange chassis in the cylindrical shell, be wrapped in miillpore filter on the porous filter screen, the drain pipe that the flange chassis is exposed in the lower end is equipped with in the porous filter screen inboard, have fluid hole on the drain pipe, the top of cylindrical shell has blast pipe, have drain tap on the blast pipe, in the inboard of porous filter screen the blast pipe that the flange chassis is exposed in the lower end is housed, its lower end has drain tap.

The utility model has solved problems of the prior art, and its filter area is big, and filtering velocity is fast, can use a few days continuously, avoided because of rupture of membranes or the poorly sealed liquid leakage that causes, the filtrate steady quality filters not retention soup in the filter that finishes.

Accompanying drawing has provided structure of the present utility model.Among the figure: (1) is feed tube, (2) be blast pipe, (3) be drain tap, (4) are cylindrical shell, and (5) are that porous filter screen (6) is a blast pipe, (7) be steam vent, (8) be fluid hole, (9) are screw, and (10) are drain tap, (11) be drain pipe, (12) are the flange chassis.

Embodiment: except that miillpore filter, other parts of the present utility model are made by stainless steel material.Cylindrical shell (4) internal diameter 180mm, wall thickness 1.5mm, high 360mm, feed tube (1) and drain pipe (11) internal diameter are 20mm, blast pipe (2), (6) internal diameter is 10mm, drain tap (3), (10) selection standard spare, blast pipe (6) upper end has a steam vent (7), the filter opening diameter 3.2mm of porous filter screen (5), its all length of side 96 orders, high 50 orders, the rectangle miillpore filter of the wide 320mm of long 50mm entirely is wrapped on the porous filter screen (5), tightly twines with the silk bandage again, and porous filter screen (5) lower end is welded on above the flange chassis (12), the diameter on flange chassis (12) is 220mm, is fastened on cylindrical shell (4) lower end by screw (9).

First filtrate after core filter stick filter filters is entered in the cylindrical shell (4), behind filtering with microporous membrane by feed tube (1), return the dosing cylinder through fluid hole (8) by the drain pipe outflow, filtrate cycle repeatedly after lamp inspection clarity is qualified, flows out can by drain pipe (11).The effect of blast pipe (2), (6) is to discharge in the cylindrical shell when filtering beginning and the gas of porous filter screen inboard, to guarantee effective filtration area.

Claims

1, a kind of infusion solutions production drum type brake fine filtering device, has the flange chassis (12) that top has the cylindrical shell (4) of feed tube (1) and is sealed in the cylindrical shell bottom, it is characterized in that also comprising that the interior lower end of cylindrical shell is fixed on the porous filter screen (5) on the flange chassis (12), be wrapped in the miillpore filter on the porous filter screen (5), and be contained in the porous filter screen (5) drain pipe (11) that has fluid hole (8) on it.

2,, it is characterized in that cylindrical shell (4) top has blast pipe (2), has drain tap (3) on the blast pipe (2) according to the described infusion solutions production drum type brake fine filtering device of claim 1.

3, according to the described infusion solutions production drum type brake fine filtering device of claim 1, it is characterized in that porous filter screen (5) inboard is equipped with blast pipe (6), blast pipe (6) upper end has steam vent (7), and its lower end has drain tap (10).
