Abstract

The utility model discloses a back-flush type bag filtering device, in particular to a bag filtering device that is suitable for chemical engineering, paint, printing ink and food service industries. In the utility model, the feed inlet of the traditional bag filtering device is arranged at the lower side of the filtering device; the direction of the liquid that flows across the filtering device is from the bottom of the filtering device to the top of the filtering device. Therefore, the back-flush type bag filtering device can utilize the gravity to make the filtering sediment not stick on a filtering screen to clog the filtering screen, the filtering effect is reinforced, and the production time is saved; meanwhile the back-flush type bag filtering device has energy saving and high efficiency. The rinsing process is very simple and convenient, the filtering device does not need to be detached, so long as a water inlet valve and a blow-off valve are opened, a material outlet valve and a material inlet valve are closed, tap water is filled from the water inlet valve, and then the filtering device can be automatically cleaned cleanly, and the back-flush type bag filtering device dispenses with the cockamamie rinsing process, and reduces the labor intensity of workers.

Description

A kind of backpulsing bag type filtering equipment
Technical field
The utility model relates to a kind of bag type filtering equipment, especially relates to the bag type filtering equipment of a kind of chemical industry, coating, printing ink, food service industry.
Background technology
Existing bag type filtering equipment all is to adopt from last charging usually, filters the mode of back from bottom discharge.Such traditional filtering mode has following shortcoming: 1. along with the carrying out of filter process, the filtrate that deposits in filter screen is more and more, and filter thing meeting blocking portion filter screen makes filter screen handle flow and diminishes, and filtration resistance increases, thereby has influenced filter effect; Handle flow simultaneously and reduce also to cause the production time to prolong, reduced production efficiency.2. after filtering end, can deposit a lot of deposits in the filter screen, screen pack must be taken out cleaning together with the deposit in the filter screen if clean, such cleaning process wastes time and energy, and has caused manpower and waste of time.
The utility model content
The purpose of this utility model is to shorten the production time in order to strengthen the filter effect of bag filter, enhances productivity, and makes it be more convenient for cleaning, dismantle and safeguard, has designed a kind of backpulsing bag type filtering equipment.
The purpose of this utility model realizes by following measure: nylon wire and stainless steel cloth are housed in the bag filter shell, nylon wire is enclosed within outside the stainless steel cloth, stainless steel cloth is placed on the ring flange of shell upper end by the ring flange of its upper end, there is a groove to place sealing gasket on the shell ring flange, so that seal between shell and the stainless steel cloth; The shell ring flange outside is connected with the fast-assembling suspension ring.The shell lower end links to each other with a threeway by fast connection interface, and two other lateral of threeway links to each other with feed pipe with blow-off pipe respectively with inlet valve by blowoff valve; A groove of laying sealing gasket is arranged on the stainless steel cloth ring flange, and loam cake places on the stainless steel cloth ring flange, and sealing gasket just can make between loam cake and stainless steel cloth, stainless steel cloth and the shell and seal after rotation fast-assembling suspension ring make it compress loam cake.Loam cake links to each other with a threeway by fast connection interface, and two other lateral of threeway links to each other with discharge nozzle with water inlet pipe respectively with bleeder valve by water intaking valve.The loam cake lower surface has welded several little steel poles, and a current dispersing tablet is located to be welded with in the lower end of these steel poles under through hole.
At the defective of traditional milling apparatus, this bag filter has been done corresponding improvement measures in design, and its advantage is:
Charging aperture be arranged on the below and the nylon filtration net cover outside stainless steel cloth, liquid is flowed through the direction of filter for from top to bottom, can utilize gravity that the filter deposition thing can be bonded at like this and stop up filter screen on the filter screen, both strengthened filter effect and also saved the living time, and also can make equipment more energy-conservation, efficient.
2. cleaning process is very easy, need not take filter apart, after only need closing bleeder valve, inlet valve and unlatching water intaking valve, blowoff valve, feeding running water from water intaking valve gets final product, the current dispersing tablet that designs below water inlet can make each corner of filter be rinsed well automatically by clear water, save cumbersome cleaning process, reduced labor strength.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is the cutaway view of the related backpulsing bag type filtering equipment of the utility model.
1 is shell, and 2 is nylon wire, and 3 is stainless steel cloth, and 4 is the shell ring flange, and 5 is the stainless steel cloth ring flange, 6,7 is sealing gasket, and 8 is the fast-assembling suspension ring, and 9 is blowoff valve, and 10 is inlet valve, and 11 is loam cake, 12 is water intaking valve, and 13 is bleeder valve, and 14,15 is fast connection interface, and 16 is the current dispersing tablet.
The specific embodiment
Assembly relation of the present utility model is as follows: nylon wire 2 and stainless steel cloth 3 are housed in the bag filter shell 1, nylon wire 2 is enclosed within outside the stainless steel cloth 3, stainless steel cloth 3 is placed on the shell ring flange 4 by the ring flange 5 of its upper end, there is a groove to place sealing gasket 6 on the shell ring flange 4, so that sealing between shell 1 and the stainless steel cloth 3; Shell ring flange 4 outsides are connected with fast-assembling suspension ring 8.Shell 1 lower end links to each other with a threeway by fast connection interface 15, and two other lateral of threeway links to each other with feed pipe with blow-off pipe respectively with inlet valve 10 by blowoff valve 9; A groove of laying sealing gasket 7 is arranged on the stainless steel cloth ring flange 5, loam cake 11 places on the stainless steel cloth ring flange 5, just can make between loam cake 11 and stainless steel cloth 3, stainless steel cloth 3 and the shell 1 and seals when rotation fast-assembling suspension ring 8 make it compress loam cake 11 after sealing gasket 6 and 7.Loam cake 11 links to each other with a threeway by fast connection interface 14, and two other lateral of threeway links to each other with discharge nozzle with water inlet pipe respectively with bleeder valve 13 by water intaking valve 12.Welded several little steel poles around the loam cake 11 lower surface center through hole, a current dispersing tablet 16 is located to be welded with in the lower end of these steel poles under through hole.
The course of work of complete equipment is: open inlet valve 10 and bleeder valve 13 during filter liquide, close blowoff valve 9 and water intaking valve 12; Liquid enters shell 1 by the inlet valve 10 of feed pipe, enters stainless steel cloth 3 after filtering through nylon wire 2, and filtrate is blocked in outside the nylon wire 2; Liquid after the filtration enters discharge pipe by bleeder valve 13 behind loam cake 11.Water intaking valve 12 and blowoff valve 9 be need open when cleaning bag filter, inlet valve 10 and bleeder valve 13 closed; Feed running water from water intaking valve 12, have the running water of certain pressure be injected in current dispersing tablet 16 backs to around splash, drop on stainless steel cloth 3 and the nylon wire 2, get final product automatic cleaning strainer, need not dismounting equipment; After the process running water washed away, filtrate was discharged from blowoff valve 9 with running water.
