Problems solved by technology

However, the filtration effect is not ideal, and the removal rate of the two types of filters for suspended solids and suspended solid particle diameter indicators cannot meet the filtration accuracy requirements of suspended solids ≤ 1mg / L and median particle size ≤ 1μm
If it is required to meet the requirements of this index, membrane technology must be used, and the technical solutions using membrane technology have membrane pollution and cleaning problems, and the industrial application in some industries is immature or the investment is too high

Embodiment 1

[0016] see figure 1 , The fiber ball filtering device comprises a water filter tank 9 and a waterway system composed of a water inlet pipe 1, a filter water outlet pipe 3, an initial filter water outlet pipe 5, a recoil water inlet pipe 4, and a recoil drain pipe 2. The incoming water inlet pipe 1 is connected to one end of the backwash water inlet pipe 4 and connected to the upper end of the water filter tank 9. The water ports at the lower ends are connected, and the exhaust pipe 6 is placed on the side of the upper end of the filter tank 9 . In the filter tank 9, a filter plate 7 that can separate the filter material is provided, and a press plate 8 that can compress the filter material is provided in addition. Pressing plate 8 is connected with transmission shaft 11 that supports it to move up and down, and its connection section adopts threaded connection. The transmission shaft 11 is connected with the transmission mechanism 13 fixed on the top of the water filter tank...

Embodiment 2

[0018] see figure 2 , the technical solution of this embodiment is exactly the same as that of the above-mentioned embodiment 1, only the combination relationship of the technical features is slightly changed, and the same parts will not be repeated. The difference is that the stirring transmission mechanism 12 is placed at the bottom of the filter tank 9 . The stirring rod 10 penetrates into the bottom of the water filter tank 9 and the filter plate 7 stretches into the filter material layer, and a sliding fit is adopted between the filter plate 7 and the connecting section of the stirring rod 10 . The usage method of this embodiment is exactly the same as that of Embodiment 1.

Embodiment 3

[0020] see image 3 , this embodiment is different from the technical solution of the above-mentioned embodiment 1. The exact same technical features will not be repeated. The difference is that the stirring transmission mechanism 12 and the stirring rod 10 are not provided in this embodiment. Instead, at the inner bottom end of the filter tank 9, a perforated pipe 14 that can be connected to an air source is provided below the filter plate 7. The difference in use is that when the filter head loss reaches 5-10 meters, the water filtration system starts to backwash. During the flushing process, start the water pump connected to the backwash water inlet pipe 4 and the blower connected to the perforated pipe 14 to carry out water and air backwash for 15 minutes. And omit the stirring process. The rest of the operation steps are exactly the same.

[0021] see Figure 4 , the schematic diagram of the structure given in the figure is a commonly used worm gear, worm transmissi...

Abstract

A filter with fibrous balls for treating water is composed of water filtering cylinder, and water channel system. Said water filtering cylinder has filtering plate for isolating filter material, pressing plate for compressing filter material, driving axle with spiral thread, driver mechanism and stirrer for back flushing. Its advantages are high filter effect, low cost and no environmental pollution.

Description

technical field [0001] The invention belongs to water treatment equipment, in particular to a device for filtering water with fiber ball filter material. Background technique [0002] At present, the filters commonly used in the water treatment industry are multi-media filters and fiber ball filters. The filter materials used in the former are mostly quartz sand, anthracite, garnet and walnut shells, etc., and the filter materials used in the latter are ordinary and modified. kind. At present, the ordinary fiber ball filter uses the weight of the fiber ball and hydraulically compresses the filter material layer, and the filtration accuracy can best reach the median particle size ≤ 3 μm, which is better than the multi-media filter. However, the filtration effect is not ideal, and the removal rate of the two types of filters for suspended solids and suspended solid particle diameter indicators cannot meet the filtration accuracy requirements of suspended solids ≤ 1 mg / L and m...
