Abstract

The utility model relates to a filter device which comprises a main pipe 6, a main flange 3 and a flange cap 1 at the top of the main pipe 6, an intake pipe 7 and an outtake pipe 8 connected with the pipeline at the out side of the main pipe 6, and a filter module in the main pipe 6. The filter module comprises a barrel type screen holder 9 and a barrel type screen 10, and are mounted on the inside wall of the main pipe 6 by a guide bracket to divide the cavity of the main pipe 6 into an internal cavity and an external cavity; wherein the internal cavity is communicated with the stretching pipe orifice of the intake pipe 7, the external cavity is communicated with the outtake pipe 8, a flushing pipe is provided at the bottom of the internal cavity, the flushing pipe reaches out from the main pipe 6 through a guide pipe 17, and a blow-off pipe 15 is provided at the bottom of the internal cavity. The utility model has the advantages of that the recoil type self-discharging filtering structure and the barrel type screen are adopted, the structure is simple, the filter area is big, the efficiency is high, the screen can self-clean, the dirt is discharged automatically, the operation is easy, the service life is long and the safety and the reliability are ensured.

Description

Backpulsing is from arranging filter
Technical field:
The utility model relates to a kind of filter.Specifically be that a kind of gas, liquid backpulsing are from arranging filter.
Background technology:
At present, various types of filters that China is commonly used, as crude oil filter, water filtering device, the capable filter of Y, air filter, no matter be flat screen type, drum-net type or basket formula etc., its complex structure, wash in order to take out filter screen, all adopt structures such as flange, gland, have that volume is big, filter area is little, dismounting is difficult, operation is inconvenient, and impurity difficulty in the scavenge unit, fluid resistance is big, inefficiency.
Summary of the invention:
The purpose of this utility model is to provide a kind of filter area big, cleans in filter screen and the device impurity, dirt and can utilize self medium to clean automatically, discharge, and easy and simple to handle, labour-saving backpulsing is from arranging filter.
Its technical scheme is: comprise and be responsible for 6, be responsible for the main flange 3 and the blind flange 1 at 6 tops, be responsible for inlet pipe 7 that 6 outsides are connected with pipeline and go out to manage 8, be responsible for the filter assemblies of 6 inside.Filter assemblies comprises cartridge type screen holder 9, barrel type filtering net 10, and be fixed on by saddle 12 and be responsible on 6 inwalls, the cavity of being responsible for 6 is spaced apart inside and outside two cavitys, wherein the internal cavity and the inlet pipe 7 extended mouths of pipe directly connect, and external cavity connects with going out pipe 8, is provided with cleaning hose in the bottom of internal cavity, be processed with micropore above the cleaning hose, the cleaning hose closed at both ends, and draw from being responsible for 6 by conduit 17, blow-off pipe 15 be provided with in the bottom of internal cavity.
Advantage of the present utility model is to have adopted backpulsing from arranging flushing mechanism, the barrel type filtering net, thereby have simple in structure, compact, filter area is big, efficient is high, screen pack can clean voluntarily, impurity discharges automatically, easy and simple to handle, long service life, safe and reliable, applicable to gas, the liquid filtering of industries such as oil, chemical industry, metallurgy, thermoelectricity.
Description of drawings:
Accompanying drawing is the structural representation of a kind of embodiment of the present utility model.In the accompanying drawing: 0, Pressure gauge; 1, blind flange; 2, pad; 3, main flange; 4, studs; 5, hex nut; 6, be responsible for; 7, inlet pipe; 8, go out pipe; 9, screen holder; 10, screen pack; 11, Intranet; 12, saddle; 13, ellipsoidal head; 14, medium-height trestle; 15, blow-off pipe; 16, lower flange; 17, flushing annex; 18, gate valve.
Specific embodiment:
Be further described below in conjunction with drawings and Examples.
Being responsible for 6 is a cylinder, and the bottom is welded with ellipsoidal head 13.Be welded with blow-off pipe 15 and irrigating catheter 17 in ellipsoidal head 13 bottoms.Irrigating catheter 17 1 ends are connected on the cleaning hose that is positioned at screen pack 10, and the other end is directly connected on the inlet pipe 7 by valve, is processed with micropore on the cleaning hose.Being responsible for 6 tops is main flange 3 and blind flange 1, is provided with pad 2 between the two, and is connected with hex nut by stud 4.The person in charge 6 the outside is provided with the inlet pipe 7 that is connected with pipeline and goes out pipe 8.Filter assemblies is equipped with in the person in charge 6 inside, and filter assemblies comprises cartridge type screen holder 9, barrel type filtering net 8, and is fixed on the person in charge's 6 inwalls by saddle 12, medium-height trestle 14, and whole person in charge's cavity is spaced apart inside and outside two cavitys.Wherein the internal cavity and the inlet pipe 7 extended mouths of pipe directly connect, external cavity with go out pipe 8 and connect.The fluid that need to filter so directly enters into the internal cavity of filter screen by inlet pipe 7, and fluid enters into external cavity after filtering, flows out by going out pipe 8, and impurity and the dirt in the fluid is deposited in the internal cavity simultaneously.Clean filter screen and remove impurity, dirt need not any instrument, the impurity in the medium, dirt are deposited in the barrel type filtering net 10, only need open the external valve of cleaning hose, open blowoff gate valve 18 and get rid of raffinates.Cleaning finishes, and closes blowoff gate valve 18 and flushing valve, opens the import and export control valve, can run well.
