Abstract

The utility model provides a fiber cloth block filter, which mainly comprises a filter pot body, a waterway and a filtering material, the filtering material adopts the composite fiber cloth block which is formed by stacking a plurality of layers of composite fiber cloth with the same size flatly and being quilted at the peripheral edge by cellosilk. The upper part of the composite fiber cloth block filtering material is provided with a filtering material pinch device. The composite fiber cloth block formed by stacking three to five layers of composite fiber cloth with the same size flatly and being quilted at the peripheral edge by cellosilk is the most favorable. The plurality of layers of equi-sized composite fiber cloth can be added with a filtration membrane with the same size for being quilted together. The diameter of the hole of the filtration membrane ranging from zero point one to zero point two micron is better in effectiveness. The composite fiber cloth block is the square shape with the size of 40-60 x 40-60mm. The optimum quadrate size is 50x50mm. The utility model has advantages of good filtering effect, high filtering speed, non affinity for oil of the filtering material and easy washing, and the filtering material need not be changed and can be regenerated according to the requirements, the service life of the filtering material is long, thus greatly reducing the cost.

Description

Fiber cloth strainer

Technical field

The utility model relates to a kind of fiber cloth strainer, is a kind of water treatment filter, especially for the processing of oil-contaminated water of oil field.

Background technology

At present, China's water treatment field is using a kind of fiber ball filtering device, as patent 00230750.When its working process was water process fiber-ball filter media, the mechanical impurity particle in the water was tackled by fiber yarn, and the mechanical impurity in the water of filter back is reduced.But this fiber ball filtering device can not be used for oily water treatment, and the fiber material that chief reason is to make this fibrous nodules is thick excessively, and is poor to the interception function of suspended substance; The fiber material of its two fibrous nodules is the lipophilic fiber, and oil is sticking secondaryly to be not easy to remove when attached to it, can't clean up, and makes this fibrous nodules become an oil group, thereby influences the filter effect of water.And the fan-shaped fibrous nodules of the taraxacum formula of symmetrical ligation, its single is easy to loose and takes off when flushing, and work-ing life is short.

Summary of the invention

The purpose of this utility model provides a kind ofly can remove mechanical impurity in the water, can remove greasy dirt in the water again, the strainer of filtering accuracy height, easy cleaning.

Technical scheme of the present utility model provides a kind of fiber cloth strainer, mainly comprise strainer tank body, water route and filtrate, its filtrate adopts the synthon cloth, and cloth is flat folded by the onesize synthetic fiber cloth of multilayer, and periphery forms with the fiber yarn quilting.

Described fiber cloth strainer is provided with the filtrate hold-down gear above synthon cloth filtrate.

Described fiber cloth strainer, synthon cloth are by the flat folded periphery fiber yarn quilting best results of 3～5 layers of onesize synthetic fiber cloth.

Described fiber cloth strainer also can add the onesize with it filtering membrane of one deck quilting together on the onesize synthetic fiber cloth of multilayer.The diameter that filters fenestra is 0.1 to 0.2 micron its better effects if.

Described fiber cloth strainer, its synthon cloth is square, size is 40～60 * 40～60mm.

Described fiber cloth strainer, its synthon cloth are square, and size is 50 * 50mm the best.

Characteristics of the present utility model are: the filtration hole of cloth can decide size according to the height of filtering accuracy, and it is constant that the filtration essence is crossed, do not come the moving influence of ripples, if there is hold-down gear auxiliary, effect can be better, can keep the flake shape of cloth with 3-5 layer cloth quilting system, not curl the filtering accuracy height.Another maximum characteristics of fiber cloth filtrate are that it has very strong hydrophilic oleophobic properties, therefore, backwash and regeneration ability extra-heavy, clear water can be removed once trembling greasy dirt, the energy mechanical stirring also can pneumaticly stir, and all can not damage fiber yarn, fiber cloth strainer of the present utility model is state-of-the art physical filtering device, and it has solved rejection of oil flied effluent and the water resources utilization and the environmental issue that efflux.The cloth that the utility model adopts is a chemical synthetic fiber cloth, suspended substance in the planar water and pollutent, good filtration effect, filtering velocity height, filtering accuracy height, and oleophylic not can also be regenerated as required at any time, need not to change filtrate, the filtrate long service life, thus greatly reduce cost.

Description of drawings

Fig. 1 is a structural representation of the present utility model.Wherein tank body 1, cloth filtrate 2, revolving stirrer 3, water-in 4, water outlet 5, filtrate hold-down gear 6, porous bearing plates 7, cylinder 8, filtrate intercepting and separating device 9.

Fig. 2 is the synoptic diagram of synthon cloth when being square.2-1 is that synthetic fiber cloth, 2-2 are the fiber yarn quiltings among the figure.

Embodiment

Embodiment of the present utility model as shown in the figure, it comprises tank body 1, and the filtrate of being made up of the synthon cloth 2 is housed in the tank body, revolving stirrer 3 is equipped with in the tank body bottom, and water-in 4 is arranged at tank body top, and water outlet 5 is arranged at the bottom, filtrate hold-down gear 6 is arranged at top, and filtrate hold-down gear 6 is driven by cylinder 8.Fig. 2 has provided the synoptic diagram when the synthon cloth is square.Fiber cloth filtrate is the special fibre silk fabrics that adopts a kind of chemosynthesis, the i.e. netted woven fabrics of being made up of the continuous fibre silk.The fiber cloth is square, and multilayer stacks, and the fiber yarn quilting is used together in four limits, and size is 40～60 * 40～60mm.The synthon cloth is a square, and size is 50 * 50mm the best.Onesize filtering membrane of quilting (diameter in its hole is at 0.1 to 0.2 micron) on the fiber cloth, its filtering accuracy is higher 10 times more than than fiber ball filter.With filtrate of 3-5 layer cloth quilting, numerous filtrate cloths constitute filtrate.The filtration hole of cloth can decide its size according to the height of filtering accuracy.Be provided with the block filtering layer-porous bearing plates 7 of cloth in the bottom of tank body, be connected with water inlet pipe 4 at the top of tank body, be connected with rising pipe 5 in the bottom of tank body, be provided with the backwash mechanical stirring device in the bottom of tank body, be provided with pneumatic filtrate hold-down gear 6 at the tank body top, hold-down gear makes the filter effect meeting better, be circumscribed with a backwash water pipe at the rising pipe place, after running to certain hour, carry out back flushing, water purification enters from lower outlet 5, start 3 pairs of filtrates of revolving stirrer 2 simultaneously and carry out the water flushing, filtrate intercepting and separating device 9 separates filtrate upper strata sump oil and mechanical impurity with filtrate 2, sump oil and mechanical impurity are discharged through last water-in 4 and connected sewage draining exit.

Core of the present utility model is a fiber cloth filtrate, and it is to be formed by multi-layer synthetic fibre cloth quilting, and its multilayer is made the flake shape that can keep cloth, does not curl the filtering accuracy height; 3～5 layers of the best, too many its sheet of maintenance that is difficult for of layer.Certainly, layer also can add a little sewing lines in the centre of fiber cloth for a long time in order to keep its sheet.In fact, the fiber cloth can be an Any shape, and as rectangle, circle etc., just square is that manufacture craft and effect are all better.The size of fiber cloth also can be unrestricted under convenient flushing and in order to be effective situation.Hold-down gear helps to improve filter effect, and its type of drive is not limited to pneumatic.

The foregoing description and accompanying drawing have provided the embodiment when the synthon cloth is square, and other shapes do not have particular requirement except that shape, therefore do not enumerate one by one.
