Abstract
The present invention relates to a fiber filter which comprises a shell body, a fixed porous supporting device, a movable porous supporting device, fiber bundle filtering elements, a water inlet and a water outlet, wherein the fixed porous supporting device and the movable porous supporting device are installed in the shell body; the fiber bundle filtering elements are fixed on the fixed porous supporting device and the movable porous supporting device; the water inlet and the water outlet are installed on the shell body. An airtight hollow box body with adjustable floatage is arranged on the movable porous supporting device. A plurality of pipes penetrating the airtight hollow box body to form passages are arranged at the airtight hollow box body. A fluid inlet pipe and a fluid outlet pipe are also arranged on the airtight hollow box body. A floating body can also be composed of a plurality of airtight hollow box bodies. The water in the airtight hollow box body can be emptied during filtration. The gravity of the movable porous supporting device and the airtight hollow box body can be completely or partially counteracted by generated floatage, and fiber bundles are ideally compressed. Air can be discharged by water during cleaning, which greatly reduces the action of the floatage. The fiber bundles are drawn by the gravity of the movable porous supporting device and the airtight hollow box body, and the upward accumulation of the fiber bundles during cleaning from bottom to top is prevented, so the fiber filter is favorable for loose cleaning.
Description
Technical field
The present invention relates to the improvement of a kind of fabric filter or fibrous filtering pool, particularly the Auto-regulating System of Density of Heavy Medium of fibre bundle filtering layer control scheme.
Background technology
ZL92230672.9 discloses a kind of fiber bundle filter scheme, and this filter is mainly by housing, active multi-hole plate, fixedly porous plate, fibre bundle constitute, and porous plate is fixed on the housing on it, and following porous plate is suspended in the bottom by fibre bundle.Water flows through the filtering layer that fibre bundle forms from bottom to top during filtration, and under the promotion of current, following porous plate moves up, and following porous plate is becoming more closely knit filtering layer with fibre bundle, and water can be from top to bottom and carry out two-way cleaning from bottom to top during cleaning.Especially from bottom to top clean to wash off more up hill and dale and dam at epimere fibre bundle body refuse, most important to guaranteeing to filter effluent quality.For guaranteeing filter effect, the weight of following porous plate is wanted the littler favourable fibre bundle compression that guarantees can move up under flow action; Be to guarantee cleaning performance, it is big that the weight of following porous plate is wanted, and guarantees to clean from bottom to top at present porous plate and do not move up and help the cleaning of loosening of fibre bundle.But this is the thatch shield to be difficult to satisfactory to both parties, exists all the time or filter effect is bad or cleaning performance is bad.
Summary of the invention
The Auto-regulating System of Density of Heavy Medium control scheme that the purpose of this invention is to provide the fibre bundle filtering layer in a kind of fiber bundle filter or the fibrous filtering pool.
Further purpose of the present invention provides the adjustable active multi-hole plate bracing or strutting arrangement of a kind of buoyancy.
In the present invention, the term fabric filter comprises the fabric filter of sealing, also comprises unlimited fibrous filtering pool, and they are referred to as fabric filter.
Fabric filter of the present invention, comprise housing, be installed in fixed support Multiple-Aperture Device and activity porous bracing or strutting arrangement in the housing, be fixed on the fiber-bundle filtering element on fixed support Multiple-Aperture Device and the activity porous bracing or strutting arrangement, and be installed in water inlet and delivery port on the housing, the adjustable buoyancy aid of buoyancy is set on activity porous bracing or strutting arrangement.
Buoyancy aid is airtight hollow box body, at casing some pipes that run through the formation passage of casing is set, and also is provided with fluid turnover pipe on casing; Can be the casing of airtight a plurality of hollows, the top of casing is peak shape, at summit is set communicating pipe, forms passage between two adjacent casing lateral surfaces, also is provided with fluid turnover pipe on casing.
Because fabric filter of the present invention, water in can the casing of emptying hollow when filtering, the buoyancy that produces is the gravity of the casing of counteracting activity porous bracing or strutting arrangement and hollow wholly or in part, or buoyancy produces thrust upwards after offsetting gravity, makes fibre bundle obtain desirable compression; Can discharge air for water when cleaning, significantly cut down buoyancy function, utilize the gravity traction fibre bundle of the casing of activity porous bracing or strutting arrangement and hollow, fibre bundle is upwards piled up when preventing to clean from bottom to top, helps loosening cleaning.The method can guarantee filter effect and cleaning performance simultaneously.
