Description

The high accuracy filter

Technical field:

The utility model relates to a kind of filter, relate in particular to a kind of from crude oil the high accuracy filter of separate solid particles (or suspension) impurity.

Background technology:

At petrochemical industry, in order to improve the purity of product, the safety of equipment such as protection pump, instrument need be used filter.At present, the filter of prior art comprises the filter body that has import and export, places the filter of filter body inside.This filter is the filter screen with protective cover, because filter screen is thinner, when fluid passed through, filter screen was stressed bigger with the not contacted position of outer support, and the time one is long, it is big that mesh becomes, some less suspended contaminations are arranged when flowing through filter, pass filter opening and enter later operation, cause filter effect bad along with fluid, influence product purity, can not effectively protect the safety of equipment such as pump, instrument; Simultaneously, filter screen is big more with outer bracing or strutting arrangement contact area, and the area that fluid passes through is just more little, and the dead angle is many more, causes filter efficiency to reduce, and the cleaning difficulty is big; Moreover filter screen is thinner, damages easily in the process of installing and using, and influences filter quality, causes loss economically.

The utility model content:

In order to overcome the deficiency in the background technology, the utility model provides a kind of high accuracy filter, and this device has good filtration effect, long service life and non-damageable characteristics.

The technical solution of the utility model is: this high accuracy filter comprises housing; the housing upper and lower has import and export respectively; inner walls is fixed with 2-5 support ring that has through hole; the chamber of housing is built-in with filter cylinder with holes and protection tube; be filled with filter core between filter cylinder and protection tube; the outer wall of protection tube touches mutually with support ring; the upper end of filter cylinder and protection tube has diffusing edge; loose along with housing in upper end support ring upper surface match; between the diffusing edge of filter cylinder and protection tube sealing ring is arranged; filter cylinder loose along on flange is arranged, flange is by being bolted on the support ring.

Have several rows of slotted hole on the above-mentioned protection tube, have several rows of circular hole on the filter cylinder; Filter cylinder and protection tube loose along on have and corresponding hole, flange bolt hole; The surfaces externally and internally of filter cylinder and protection tube all has nano coating; Have on the flange to open and portal.

The beneficial effect that the utlity model has is: this device good filtration effect, and long service life, the work period is long; filter is not easy to damage, and filter effect is remarkable, improves product purity; effectively protect the safety of pump, instrument, apparatus surface is smooth, and is nonpolarity; the resistance of convection cell is less; improve flow velocity, promote filter quality, simultaneously; nano coating also has bactericidal action, effectively the microorganism in the eliminate fluid.

Description of drawings:

Accompanying drawing 1 is a structural representation of the present utility model;

Accompanying drawing 2 is structural representations of flange in the accompanying drawing 1;

Accompanying drawing 3 is structural representations of filter cylinder;

Accompanying drawing 4 is structural representations of protection tube.

1-filter cylinder among the figure, 2-flange, 3-are protected tube, the 4-filter core, and the 5-housing, the 6-small sealing ring, the 7-sealing ring, the 8-circular hole, the 9-slotted hole, the 10-support ring, the 11-outlet, the 12-import, 13-bolt hole, 14-open and portal, the 15-through hole.

The specific embodiment:

The utility model is described in further detail below in conjunction with accompanying drawing: this high accuracy filter comprises housing 5; housing 5 upper and lowers have respectively into; outlet (12; 11); housing 5 inwalls are fixed with 2-5 support ring 10 that has through hole 15; the chamber of housing 5 is built-in with filter cylinder with holes 1 and protection tube 3; have even several rows of slotted hole 9 on the protection tube 3; it is a kind of protective device of making by corrosion resistant plate; filter cylinder 1 is to have even circular hole 8; the titanium plate of HTHP moulding is made; filter cylinder 1 and protection tube 3 are suitable;

filter cylinder

1 and 3 in protection tube are filled with filter core 4; like this; less exactly suspended particulate impurity is when flowing through cartridge filter 1 along with fluid; also can be filtered, filter effect is remarkable, improves product purity; effectively protect pump; the safety of instrument; simultaneously, place the described stainless steel protection tube 3 of filter core outer surface, filter core is not damaged in the process of installing and using.The outer wall of protection tube 3 touches mutually with support ring 10; the upper end of filter cylinder 1 and protection tube 3 has diffusing edge; loose along matching with housing 5 interior upper end support ring 10 upper surfaces; between the diffusing edge of filter cylinder 1 and protection tube 3 sealing ring 7 is arranged; filter cylinder 1 loose along on the flange 2 that matches with housing 5 internal diameters is arranged; 2 of the diffusing edge of filter cylinder 1 and flanges have last sealing ring 6, can prevent effectively that fluid from flowing to from the gap of 10 of edge and filter cylinder 1 wall, support rings, also avoided bringing into the possibility of smaller particles impurity.Flange 2 is by being bolted on the support ring 10.

Filter cylinder 1 and protection tube 3 loose along on have and 13 corresponding holes, flange bolt hole, have to open on the flange 2 simultaneously and portal 14, when installing and clean, conveniently install and propose.

The surfaces externally and internally of filter cylinder 1 and protection tube 3 all is coated with has the bactericidal action nano coating, and smooth surface is nonpolarity; the resistance of convection cell is less, improves flow velocity, promotes filter quality; simultaneously, nano coating also has bactericidal action, effectively the microorganism in the eliminate fluid.

Because filter core 4 and filter cylinder 1 replaceable other different sizes of filter also are applicable to the processing to oil-polluted water, sanitary sewage etc.This high accuracy filter is specially adapted to the filtration that oil-field thick-oil transports.
