Description
Technical field
The utility model relates to a kind of tubular filter, and particularly a kind of Filter-bag carcass of tubular filter is applied to the Separation of Solid and Liquid field.
Background technology
The screen pipe parts of existing tubular filter are comprised of filter bag and Filter-bag carcass.Filter-bag carcass mainly is comprised of flange 7, pull bar 9, fiberglass screen pipe 10 etc.The hollow fiberglass screen pipe 10 of multistage is serially connected by pull bar 9, and disk and flange 7 amongs on top mounting flange 7, fiberglass screen pipe 10 and the pull bar 9 add a rubber washer (8,11), in case fiberglass screen pipe 10 is damaged by pressure.In order to prevent spilling the slit of filtered fluid between flange 7 tops and pull bar 9, flange 7 tops increase packing seal 5, and packing seal 5 is played sealing function by sealing gland 4 under the effect of nut 2 and plain washer 3.Suspension ring 1 are installed on pull bar top, are used for lifting by crane Filter-bag carcass.
Behind the terylene filter bag 12, be installed in the installing hole of tubular filter on the Filter-bag carcass outer cover.Enter turbid liquid in the tubular filter under the effect of filter pressure, liquid passes filter bag 12 from the outside, enters the internal cavities of screen pipe 10 by the aperture on the fiberglass screen pipe 10, forms pure filtered fluid.Pure filtered fluid upwards flows, from filtrate (liquid 6 outflow filters on flange 7 tops.Impurity in the turbid liquid under the obstruction of filter bag 12, has been retained the outside of filter bag 12, and collects in filter cylinder bottom formation filter residue after filter bag 12 comes off.Like this, just reached the purpose of Separation of Solid and Liquid.
Existing this fiberglass Filter-bag carcass has the following disadvantages: (1) because the rigidity of fiberglass is less, and temperature tolerance is poor, so easily distortion and the damage of fiberglass screen pipe, service life is very short.(2) tubular filter filters from outside to inside, because the effect of external pressure, filter bag tightly is wrapped on the outer surface of fiberglass screen pipe, so only have the filter cloth at aperture place on the fiberglass screen pipe just can play effective filtration.But the area sum of aperture will be far smaller than the area of filter bag, so can not take full advantage of the filter bag filter area, filter efficiency is very low.(3) number of spare parts of fiberglass skeleton is many, and complex structure is made, maintenance workload is large.
The utility model content
The purpose of this utility model is exactly in order to overcome the weak point in the background technology, designs a kind of long service life, brand-new Filter-bag carcass that filter efficiency is high, simple in structure, easy to maintenance.
The purpose of this utility model is achieved through the following technical solutions.
A kind of Filter-bag carcass of tubular filter comprises suspension ring 13, closure plate 14, snap joint 15, pipe 16 and flange 17,
Pipe 16 passes flange 17 and is the hollow tube-shape structure, welding snap joint 15 on the pipe, and pipe 16 1 ends welding closure plate 14, welding hanging ring 13 on the closure plate 14, it is characterized in that:
Connect many straight wires on the described pipe other end circumference, form the hollow tube-shape structure.
Above-mentioned Filter-bag carcass is characterized in that: also have an end cap and straight wire other end welding.
Above-mentioned Filter-bag carcass is characterized in that: described straight wire evenly distributes along circular tube circumference.
Above-mentioned Filter-bag carcass is characterized in that: also have one or more wire to be wrapped on the straight wire cylinder circumference.
Above-mentioned Filter-bag carcass is characterized in that: described one or more wire is helical form or circular wire, distributes along wire drum outer wall or inwall, or becomes cage structure with straight wire weaving.
Above-mentioned Filter-bag carcass is characterized in that: described straight wire has 8.
Above-mentioned Filter-bag carcass is characterized in that: described end cap is spherical structure.
Above-mentioned Filter-bag carcass is characterized in that: porose in the middle of the described end cap.
Above-mentioned Filter-bag carcass is characterized in that: described Filter-bag carcass material is stainless steel.
Above-mentioned Filter-bag carcass is characterized in that: described connected mode also can be bonding.
The wire of straight inboard welding coil spring shape wiry, so straight wire and spiral metal wire have just formed a firmly elongated cylindrical cage; Wire can be helical form or circular, also can be woven on the straight wire and form cage structure;
Welding end cap in cage bottom avoids the end of straight wire and spiral metal wire to expose;
End cap is spherical structure, and a hole is opened in the centre, can avoid liquid collecting;
Weld snap joint on the pipe, the snap joint internal cavities communicates with the pipe cavity;
The top welding closure plate of pipe, welding hanging ring on the closure plate;
Make the used material of this Filter-bag carcass, can be according to different choice titanium or stainless steel or other metal materials of filtered fluid, to reach anticorrosive and purpose that increase the service life, connection also can be adopted bonding between the different parts simultaneously.
The beneficial effects of the utility model: the designed Filter-bag carcass of the utility model in use, filter bag 12 of cage type skeleton outer cover.Compare with background technology, (1) can take full advantage of the filter area of filter bag 12, so filter efficiency is higher owing to there is the cage type skeleton to support.(2) because this skeleton mainly is comprised of wire, so the material that uses is less, lightweight, cost is low.(3) skeleton is made by metal material, so intensity is high, and long service life.(4) skeleton is Welding Structure, does not have movable members, thus simple in structure, manufacturing and easy to maintenance.
