Embodiment 1

[0012] Embodiment 1: Referring to Figures 1 and 2, the adjustable fiber filter of this embodiment is a forward filter structure, which has a shell 1, and the shell 1 is composed of upper and lower heads and a middle cylinder through welding. A water inlet 9 and an exhaust port 10a are provided on the upper head of the housing 1, and a water outlet 18 and an air inlet 17 of the gas distribution device 15 are provided on the lower head of the housing 1. In the housing 1 The lower end is provided with a fixed orifice plate 2, and the upper end of the housing 1 is provided with a floating orifice plate 6. The fiber bundle filter material 3 is placed between the fixed orifice plate 2 and the floating orifice plate 6, and the two ends of the fiber bundle filter material 3 are respectively connected to the The fixed orifice plate 2 and the floating orifice plate 6 are fixedly connected. A manhole 20 is provided on the housing 1 . A filter material density adjusting device 8 is arran...

Embodiment 2

[0014] Embodiment 2: With reference to Fig. 3, the adjustable fiber filter of the present embodiment is a reverse filter structure, and its basic structure is the same as that of Embodiment 1, the only difference is that the water outlet 18 (i.e. the cleaning water inlet) is located in the shell On the upper head of the body 1, the water inlet 9 (that is, the cleaning water outlet) is set on the lower head of the shell 1, the fixed orifice 2 is set on the upper end of the shell 1, and the floating orifice 6 is set in the shell 1 At the lower end, the filter material density adjustment device 8 is arranged in the housing 1 and located below the fiber bundle filter material 3 . In the center of the housing 1 there is no guide support pipe 4 for the filter material density adjustment device 8 .

[0015] Working principle: when filtering, open the water inlet 9, the filter material density adjustment device 8 becomes an empty tank (not filled with water) and becomes a floating tan...

Embodiment 3

[0016] Embodiment 3: Referring to Figure 4, this adjustable fiber filter is suitable for application in a filter pool. Its structure is basically the same as that of Embodiment 1, the only difference is that the shell 1 is a pool-shaped structure made of steel and concrete. In the center of the housing 1 there is no guide support pipe 4 for the filter material density adjustment device 8 . There is no guide wheel 19 in contact with the housing 1 on the side wall of the frame 5 of the filter material density adjusting device 8 . Its working principle is identical with embodiment 1.

Abstract

The invention relates to a separating device, which is an adjusting fiber filter used for water and aqueous solution comprising a shell body, a water inlet and a water outlet are arranged on the shell body, a fixed orifice plate and a floating orifice plate are arranged in the shell body, a fiber cluster material positioned between a fixed orifice plate and a floating orifice plate is provided with a filter material density adjusting device and the gas mixing equipment, the invention is characterized in that: the filter material density adjusting device has the structures that a frame is arranged on the device for fixedly connecting with the floating orifice plate, a closed water chamber is arranged in the frame, a plurality of aqueducts are arranged in the closed water chamber, a square-cavity of the closed water chamber is connected with an exhaust pipe, a water filling pipe and a drainage pipe by a soft cannula; a directive wheel contacting with the shell body is arranged on the side wall of the frame; the center in the shell body is provided with a guiding support pipe; the floating orifice plate may be a screen mesh. The invention can closely pile and press or fully extend and loosen the fiber cluster material through the filter material density adjusting device, and has advantages of high filtering precision, large area, high capacity of pollutant cutting, long filtering period, large water preparation amount, good filtering quality and reliable performance.

Description

technical field [0001] The invention relates to a separation device, which is an adjustable fiber filter for water and aqueous solution. Background technique [0002] Chinese utility model patent, patent No. 97250476.1 has opened a kind of fiber filter, and its main feature is: some fiber bundles are evenly distributed between the fixed orifice plate and the movable orifice plate, rely on the natural momentum of entering and exiting water to adjust the fiber porosity. The shortcoming of this equipment is that relying on the natural impetus of water, the fiber bundle filter material cannot be compacted or fully stretched and loosened, and the purpose of adjusting the porosity of the fibers and the requirements of high-precision water quality cannot be achieved, and the filtration resistance is large. Contents of the invention [0003] The technical problem to be solved by the present invention is to substantially improve the existing technology and provide a fiber bundle fi...
