Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and in particular to a water treatment fiber filter media and a high-speed water treatment filtration device. Background Technology

[0002] Currently, downstream equipment manufacturers of high-speed filtration devices in the water treatment field mainly use imported filter media, which are relatively expensive. Other fiber filtration products used in the industry have problems such as poor product performance and durability. For example, during the backwashing process of high-speed filtration equipment, the filter media is repeatedly washed and turbulent by water and air flow in the raw water of the filter tank. This stage has a large physical impact on the outer layer of the filter media. The filter media is usually round, and it is easy for it to break and scatter during this stage. This not only affects the overall filtration effect, but also brings new solid residues, which can easily cause clogging of the perforated plate below. Moreover, this technical problem has not yet been effectively solved. Utility Model Content

[0003] The purpose of this invention is to provide a water treatment fiber filter media and a high-speed water treatment filtration device to solve the problems existing in the prior art, enhance the filter media's resistance to physical impact during the backwashing stage of the high-speed filtration device, improve its durability, and achieve the effect of not being easily broken or dispersed.

[0004] To achieve the above objectives, this utility model provides the following solution: This utility model provides a water treatment fiber filter media, which has a short columnar structure. The outer periphery of the filter media is integrally formed with a number of toothed ribs along the axial direction, and the toothed ribs are distributed circumferentially with the axis of the filter media as the center.

[0005] Preferably, the toothed ribs are evenly distributed around the center of the filter media's axis.

[0006] Preferably, the cross-section of the filter media is pentagonal or gear-shaped.

[0007] This utility model also provides a high-speed water treatment filtration device, including a filter tank, wherein a filter media layer is provided inside the filter tank, and the filter media layer is composed of a plurality of water treatment fiber filter media stacked together.

[0008] Preferably, the filter media layer is disposed on the top of the porous plate.

[0009] The present invention achieves the following technical advantages over the prior art: The water treatment fiber filter media and high-speed water treatment filtration device of this utility model have several toothed ribs integrally formed on the outer circumference of the filter media column, so that the cross-section forms a shape such as a pentagon or a gear, which increases the original cylindrical surface area, enhances the filter media's ability to resist physical impact during the backwashing stage of the high-speed filtration device, improves its durability, and achieves the technical effect of not being easily broken or dispersed.

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] The purpose of this invention is to provide a water treatment fiber filter media and a high-speed water treatment filtration device to solve the problems existing in the prior art.

[0014] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0015] Example 1: like Figure 1As shown, the water treatment fiber filter media 1 in this embodiment has a short columnar structure. Several toothed ribs 2 are integrally formed on the outer periphery of the filter media along the axial direction. The toothed ribs 2 are evenly distributed circumferentially with the axis of the filter media as the center.

[0016] In this specific embodiment, the cross-section of the filter media is a pentagonal star shape or a gear shape.

[0017] In this embodiment, the water treatment fiber filter media 1 has a toothed rib structure on the cylindrical surface, which changes from a circular cross-section to a multi-toothed structure, preferably a pentagonal star or gear shape. This surface structure can increase the outer surface area, thereby increasing the stress area of ​​the filter media during backwashing and improving its resistance to physical impact during backwashing, thus improving its durability.

[0018] In this embodiment, the short column structure of the water treatment fiber filter media 1 is formed by cutting long column materials after processing them with a five-pointed star mold or a gear-shaped mold in the fixed forming area mold tube.

[0019] Example 2: like Figure 2 , Figure 3 As shown, in this embodiment of the high-speed water treatment filtration device, a filter media layer 4 is provided inside the filter tank 3. The filter media layer 4 is formed by stacking several water treatment fiber filter media 1 as described in Embodiment 1; and the filter media layer 4 is disposed on the top of the porous plate 5.

[0020] The high-speed water treatment filtration device in this embodiment includes a filtration state and a backwashing state during operation.

[0021] The filtering process works as follows: like Figure 2 As shown, the water treatment fiber filter media 1 is freely stacked above the perforated plate 5 in the filter tank 3. The water level above is controlled to be the same height as the filter media layer 4 by controlling the water outflow rate. Positive filtration is performed by the weight of the water. The raw water enters the filter device through the water inlet pipe 6 at the top of the filter tank 3, passes through the filter media layer 4 and the perforated plate 5 from top to bottom by gravity, and is discharged through the bottom drain pipe 7. The suspended solids (SS) in the raw water are captured and intercepted by the filter media layer 4.

[0022] The backwashing process is as follows: like Figure 3As shown, first close the raw water inlet valve 8 and the filter outlet valve 9, and open the backwash drain valve 10 to lower the water level in the filter tank 3. After the water level drops to the set level, start the backwash blower 11 and open the raw water inlet valve 8 to enter the "air-water backwash" stage. After the backwash blower 11 and the backwash air inlet valve 12 are closed, the raw water inlet valve 8 and the backwash drain valve 10 are kept open for "water washing". After the backwash blower 11 and the backwash air inlet valve 12 are closed, the raw water inlet valve 8 and the backwash drain valve 10 are kept open for "water washing". After the backwash blower 11 is closed, the filter outlet valve 9 is opened and the backwash drain valve 10 is closed to enter the next filtration cycle.

[0023] In this specific embodiment, specific examples are used to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
