The meshy or striped fixed underframe is welded by stainless steel outer ring, screen mesh (11) or striped steel, with their shape and size being determined in accordance with the shape of the filter, wherein the side length of the rectangular orifice of the screen mesh (11) is 9 to 20 mm. The long fiber filtration materials adopt polyester fiber or acetate fiber, with the fiber diameter being 15 to 50 mum and the length of the fiber cantilevered end is 1.2 to 1.5 m. The components are characterized in high filtration speed, easy backwash and so on, which can improve the water yield rate, pollution receiving ability and backwash effects, make the effluent quality better, economize the energy consumption and make the bed frame light.
Description
Technical field
The utility model is the core processing unit during feedwater and all kinds of dirt (giving up) water filtration are handled, and belongs to the technical field that water filtration is handled.
Background technology
Filtration be in all kinds of water treatments in order to one of the most frequently used treatment process of removing suspension (turbid matter) and adsorbed material thereof, filter assemblies then is the most critical factor of decision filter capability.Chang Yong sand filtration in the past not only have than great, filtration resistance is big, filtering velocity is low, backwash is difficult, carrier is easy to shortcomings such as loss, also little because of specific area, the low filter capacity that influences the filter tank of water environment capacity.Group's come-up during then because of structural closure and backwash such as fibrous nodules makes it be difficult to clean, and has influenced the lasting effect that filters greatly.
Summary of the invention
Technical problem: the purpose of this utility model provides a kind of beetling and cantilevered type long fibre high-rate fitration assembly, this filter assemblies has characteristics such as filtering velocity height, backwash be easy, can improve producing water ratio, water environment capacity, backwash effect to greatest extent, improve effluent quality, energy efficient, and make a body lightness.
Technical scheme: beetling and cantilevered type long fibre high-rate fitration assembly of the present utility model is made up of filtering material and fixture, this assembly comprises netted or strip fixed frame and long fibre filter material, the long fibre filter material takes the shape of the letter U to hang and ties on the opposite side of screen cloth in netted or strip fixed frame, and the cantilever end of long fibre filter material freely is suspended in the current.Netted or strip fixed frame is formed by stainless steel outer ring, screen cloth or strip reinforcing bar weldering system, and profile and size netted or the strip fixed frame are decided according to the shape of filter, and the rectangle eyelet length of side of screen cloth is 9～20mm.The long fibre filter material adopts polyester fiber or acetate fiber material, and fibre diameter is 15～50 μ m, and fiber cantilever end length is 1.2～1.5m.
Beneficial effect:
1) the experimental study result that carried out of applicant shows, the bottom fixed form and the compartment system of fiber module are huge to the influence of bed resistance, wear and adopt outstanding knot cantilevered fashion to collude, can avoid to greatest extent causing reducing of circulation area because of fixed, thereby several times ground improves filtering velocity, can reach more than the 65m/h;
2) take an end untwisting one end cantilever-designed freely, compared with the sand filtration of generally adopting both at home and abroad at present, two ends anchoring fiber assembly, fibrous nodules etc., when reducing filtration resistance, make full use of the fiber free end in water with the chance state, under the out-of-balance force effect of water and bubble, violent frictional impact has improved the backwash effect effectively, reduce backwash time and water, gas consumption, saved energy consumption;
3) fibrous material of the suitable diameter of selection utilizes body gently to reach the own elasticity function, and voidage reaches 80-90% when guaranteeing to filter, and has improved producing water ratio and backwash effect;
4) filametntary huge specific area and contamination capacity have improved effluent quality effectively, have prolonged the backwash cycle.
Description of drawings
Fig. 1 is a general structure schematic diagram of the present utility model, wherein has netted or strip fixed frame 1, long fibre filter material 2.
Fig. 2 is the local enlarged diagram of netted fixed frame 1 of the utility model and the outstanding knot mode of fiber, and screen cloth 11 is wherein arranged.
When Fig. 3 was filtration, bear building-up got loose, filter material is presented and dredged the schematic diagram of close form down, arrow " ↓ " expression water (flow) direction wherein.
Fiber was strained when Fig. 4 was the utility model backwash, the screen cloth fiber soars the form schematic diagram.
The specific embodiment
According to the filter form of fracture and install and fix mode, the distance of making in advance between a certain size size, the rectangle eyelet length of side or the strip reinforcing bar is the screen mesh type fixed frame of 9-20mm.In line with reducing filtration resistance, being easy to the aim that backwash and fiber do not run off, and make full use of the own elasticity and the surperficial frictional resistance characteristic of fiber, selecting diameter is the polyester fiber (or acetate fiber) of 15-50 μ m, adopt to collude continuously and wear or the lattice list is worn mode, it is taken the shape of the letter U directly encircle on the opposite side steel wire or strip reinforcing bar of rectangular mesh.Do like this, make stiff end pine and not taking off when filtering, the symmetry tension screen cloth space of soaring gradually when reducing filtration resistance, backwash greatly, thus reduce the backwash resistance.
Below, creation is described further to utility model to reach embodiment in conjunction with the accompanying drawings.
Fig. 1 is the assembly master drawing of first embodiment of the utility model.Netted or the strip fixed frame 1 of stainless steel is wherein arranged, long fibre filter material 2.Embodiment middle filtrator internal diameter is 1.2m, so the stainless steel underframe adopts flat of wide 20mm, thick stainless steel for 5mm, it at diameter the circular housing that bends to internal diameter 1.2m (external diameter is 1.21m) on the internal mold of 1.2m, housing is interior with flat of the stainless steel of wide 15mm, thick 3mm, carry out parallel reinforcement of weld (reinforcement) by the 20cm spacing, laying and spot welding layer of steel wire diameter are 1mm on the reinforcement, and the inwall distance is the rectangular mesh stainless steel mesh of 9mm * 9mm.
Fig. 2 is a fiber module weaving method schematic diagram.Wherein 1 is the stainless steel rectangular screen cloth, and 2 is braided fiber.Design philosophy according to the utility model creation, carried out the creation of 3 aspects in the fibrage: 1. for effectively reducing filtration resistance and improving the backwash effect, take the U type to hang the eliminant weaving manner between bottom fiber and steel wire, through the embodiment evidence, not only filtration resistance is little, maximum rate of filtering reaches more than the 65m/h, and the braiding process is comparatively easy; 2. top does not have fixingly, for full free style cantilever, like this, freely swings under the acting in conjunction of water, gas during backwash, has increased friction and collision to each other effectively, is beneficial to coming off of filter residue, has shortened the backwash time; During filtration, presenting and dredge closely down, is typical multiple filtration structure, can give full play to the retaining power of filtering layer; 3. the specific fiber surface in the reactor is long-pending is the key factor of decision water environment capacity.Take all factors into consideration the factor such as effective time of staying, effluent quality, backwashing period of filtration, it is 1.5m that present embodiment is got the fiber jib-length, densification during filtration highly is about 1.0m, then effectively the fillter section height is about 1.0m, adopt the fiber of 35 μ m diameters, then effectively the section fibre specific area is pressed 10000m
2/ m
3When (reactor volume) carries out designing and calculating, about 6000 of fiber should be arranged in every lattice, the every bunch of fiber that colludes when wearing is about 3000.
