Description

Technical Field

[0001] The present invention relates to the technical field of filtration equipment, and in particular to an efficient backwashing carpet-type fiber filter. Background Art

[0002] Fiber filters are relatively common filtration devices, mainly composed of a filter tank body and fiber filter media. Currently, commonly used fiber filter media include fiber bundle filter media and fiber ball filter media. The fiber bundle filter media filters in a compacted state and is backwashed in a relaxed state. The existing fiber filters have the following problems: First, most of the existing installation methods are to bundle the ends of the fiber bundles and then tighten them with rubber bands or springs. After a long time, this installation method will cause the bundled positions of the fiber bundles to form a mass and cannot be evenly laid flat on the surface of the filter box. This dead corner part cannot be effectively solved during backwashing, thus affecting the filtration effect. Second, simply using backwashing water for flushing, the backwashing effect is not ideal and needs to be improved. Third, most of the backwashing pipelines are installed inside the filter, occupying a large amount of space and bringing inconvenience to the maintenance of the filter. Summary of the Invention

[0003] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide an efficient backwashing carpet-type fiber filter in which the fiber bundles can maintain a uniformly laid flat state for a long time, have good filtration effect, better backwashing effect, and are convenient for maintenance.

The hanging plates are connected to the filter box through evenly distributed tension springs. A circular fiber bundle is densely arranged between the two hanging plates. Cross bars pass through the top and bottom ends of the fiber bundle. Hooks for supporting the ends of the cross bars are fixedly arranged on the hanging plates. A clamping plate cover buckling on the cross bar is arranged outside the hanging plate to respectively press and fix the top and bottom ends of the fiber bundle. The clamping plate cover is fixedly connected to the hanging plate through bolts. An outer rubber strip is arranged at the part where the clamping plate cover presses on the fiber bundle, and an inner rubber strip is arranged on the hanging plate corresponding to the outer rubber strip;

[0008] A vibration assembly, fixedly connected to the top end of the carpet-type filtration assembly, is used to drive the carpet-type filtration assembly to vibrate. The vibration assembly includes a pneumatic vibrator. An installation plate is integrally connected to the hanging plate. The pneumatic vibrator is fixedly installed on the installation plate. The pneumatic vibrator is connected to a docking head through an air pipe, and the docking head is connected to an air compressor through a high-pressure pipeline.

[0009] A backwashing assembly is arranged outside the tank body, and its output end extends into the tank body to backwash the carpet-type filtration assembly.

[0010] A sewage discharge assembly is arranged at the bottom of the tank body and is respectively communicated with the tank body and the filtration tank, and is used to discharge the sewage for backwashing the carpet-type filtration assembly. The sewage discharge assembly includes a first sewage discharge pipe and a second sewage discharge pipe arranged at the bottom of the tank body.

[0013] Further, the shell of the pneumatic vibrator is made of stainless steel materials.

[0014] Further, the backwashing assembly includes 360-degree high-pressure nozzles respectively arranged outside the carpet-type filtration assembly near the inner wall of the tank body. A main water pipe is arranged on one side of the tank body. One end of the main water pipe is respectively communicated with the 360-degree high-pressure nozzles through a branch water pipe, the other end of the main water pipe is communicated with a high-pressure water pump, and a one-way valve is arranged on the main water pipe.

[0015] Further, a water inlet is communicatedly arranged on one side of the tank body, and a water baffle is fixedly arranged on one side of the filtration tank corresponding to the water inlet; an outlet communicated with the filtration tank is arranged on the other side of the tank body.

[0041] Carpet-type filter assembly 3, respectively arranged on both sides of the filter box 2 and covering the filter holes 21;

[0042] Vibration assembly 4, fixedly connected to the top of the carpet-type filter assembly 3 and used to drive the carpet-type filter assembly 3 to vibrate;

[0043] Backwashing assembly 5, arranged outside the tank body 1, and its output end extends into the tank body 1 and is used to backwash the carpet-type filter assembly 3;

[0044] The sewage discharge assembly 6 is arranged at the bottom of the tank body 1 and is respectively communicated with the tank body 1 and the filter tank 2, and is used for discharging the sewage for backwashing the carpet-type filter assembly 3.

[0045] In this embodiment, the fiber filter of the present application is composed of a tank body 1, a filter tank 2, a carpet-type filter assembly 3, a vibration assembly 4, a backwashing assembly 5 and a sewage discharge assembly 6. The fiber filter uses the carpet-type filter assembly 3 to filter water, and the filtering effect is good.

[0046] After the fiber filter is used for a period of time, the carpet-type filter assembly 3 is backwashed by the cooperation of the vibration assembly 4 and the backwashing assembly 5, and the backwashing effect is good.

[0047] In a preferred embodiment, as Figure 3 and Figure 4 shown, the carpet-type filter assembly 3 includes hanging plates 31 arranged near the top and near the bottom on one side of the filter tank 2. The hanging plates 31 are connected to the filter tank 2 through uniformly distributed tension springs 32. An annular fiber bundle 33 is densely arranged between the two hanging plates 31. Cross bars 34 pass through the top and bottom ends of the fiber bundle 33. Hooks 35 for supporting the ends of the cross bars 34 are fixedly arranged on the hanging plates 31. Clamping plate covers 36 buckled on the cross bars 34 are arranged on the outer sides of the hanging plates 31 for respectively pressing and fixing the top and bottom ends of the fiber bundle 33. The clamping plate covers 36 are fixedly connected to the hanging plates 31 through bolts. Outer rubber strips 37 are arranged at the parts where the clamping plate covers 36 press on the fiber bundle 33, and inner rubber strips 38 are arranged on the hanging plates 31 corresponding to the outer rubber strips 37.

[0048] In this embodiment, after the fiber bundle 33 is laid flat, it is tightened by the cross bar 34, and then the two ends are clamped and fixed by the cooperation of the hanging plate 31 and the clamping plate cover 36 to form a structure similar to a carpet. The problem of clustering due to dirt accumulation of the knotting type fixing structure is avoided. The fiber bundle 33 can be kept evenly laid flat for a long time, ensuring the filtering effect of the fiber filter.

[0049] The inner and outer sides of the ends of the fiber bundle 33 are clamped and fixed by the outer rubber strip 37 and the inner rubber strip 38, and the fixing effect is good and the fiber bundle 33 is not easily damaged. The hanging plate 31 is connected to the filter tank 2 through the tension spring 32, so that the vibration assembly 4 can drive the hanging plate 31 to shake, thereby shaking off the dirt on the fiber bundle 33.

[0050] In a preferred embodiment, as Figure 3 and Figure 5 shown, clamping grooves 22 are arranged at both ends of the filter tank 2 where the hanging plates 31 are located, and both ends of the hanging plates 31 are respectively swingably clamped in the clamping grooves 22.

[0051] In this embodiment, the hanging plate 31 is connected to the filter tank 2 through the card slot 22, and there is a movable gap of 2-3 mm between the hanging plate 31 and the card slot 22, enabling the hanging plate 31 to vibrate within a certain range, avoiding damage to the structure of the carpet-type filter assembly 3 due to excessive vibration amplitude, and improving the structural safety.

[0052] In a preferred embodiment, the hanging plate 31, the cross bar 34, the clamping plate cover 36 and the card slot 22 are all made of stainless steel materials, with high structural strength, not easily deformed, not easily corroded and rusted, and long service life.

[0053] In a preferred embodiment, as Figure 3 and Figure 6 shown, the vibration assembly 4 includes a pneumatic vibrator 41. An installation plate 39 is integrally connected to the hanging plate 31, and the pneumatic vibrator 41 is fixedly installed on the installation plate 39. The pneumatic vibrator 41 is connected with a docking head 43 through an air pipe 42, and the docking head 43 is connected to an air compressor through a high-pressure pipeline.

[0054] In this embodiment, the docking head 43 penetrates through the tank body 1 in a sealed manner, realizing the connection between the pneumatic vibrator 41 and the air compressor. The air compressor drives the pneumatic vibrator 41 to vibrate, thereby driving the fiber bundle 33 to vibrate through the hanging plate 31, shaking off the dirt thereon, and greatly improving the backwashing effect of the filter.

[0055] In a preferred embodiment, the outer shell of the pneumatic vibrator 41 is made of stainless steel material, not easily corroded and rusted, and has a long service life.

[0056] In a preferred embodiment, as Figure 1 and Figure 2 shown, the backwashing assembly 5 includes 360-degree high-pressure nozzles 51 respectively arranged on the outer side of the carpet-type filter assembly 3 close to the inner wall of the tank body 1. One side of the tank body 1 is provided with a main water pipe 52. One end of the main water pipe 52 is respectively communicated with the 360-degree high-pressure nozzles 51 through a branch water pipe 53, and the other end of the main water pipe 52 is communicated with a high-pressure water pump. A one-way valve 54 is arranged on the main water pipe 52.

[0057] In this embodiment, the backwashing assembly 5 uses a high-pressure water pump for water supply, and backwashes the carpet-type filter assembly 3 through the 360-degree high-pressure nozzles 51. The backwashing force is large, the uniformity is good, and the backwashing effect is excellent. According to the length of the carpet-type filter assembly 3, 1-3 groups of 360-degree high-pressure nozzles 51 are correspondingly set to form full coverage thereof to ensure the backwashing effect.

[0058] The main water pipe 52 and the branch water pipe 53 for water supply are both arranged on the outer side of the tank body 1 and are connected to the 360-degree high-pressure nozzles 51. It greatly reduces the occupation of the space inside the tank body 1, enables there to be more sufficient maintenance space inside the tank body 1, and is convenient for maintenance.

[0059] In a preferred embodiment, as Figure 1 and Figure 3 shown, the sewage discharge assembly 6 includes a first sewage discharge pipe 61 and a second sewage discharge pipe 62 disposed at the bottom of the tank body 1. The first sewage discharge pipe 61 is communicated with the bottom of the tank body 1, and the second sewage discharge pipe 62 extends into the tank body 1 and is communicated with the bottom of the filter tank 2. A first sewage discharge valve 63 is disposed on the first sewage discharge pipe 61, and a second sewage discharge valve 64 is disposed on the second sewage discharge pipe 62.

[0060] In this embodiment, the backwash sewage in the tank body 1 can be discharged by controlling the first sewage discharge valve 63; the backwash sewage in the filter tank 2 can be discharged by controlling the second sewage discharge valve 64. To cooperate with the backwashing of the filter.

[0061] In a preferred embodiment, as Figure 1 and Figure 2 shown, a water inlet 11 is communicatively provided on one side of the tank body 1, and a water baffle 23 is fixedly provided on one side of the filter tank 2 corresponding to the water inlet 11; a water outlet 12 communicated with the filter tank 2 is provided on the other side of the tank body 1.

[0062] In this embodiment, water enters the tank body 1 through the water inlet 11. After hitting the water baffle 23, it directly falls, and the water baffle 23 forms a protection for the filter tank 2. The water enters the filter tank 2 after being filtered by the carpet-type filter assembly 3 and is then output through the water outlet 12 to complete the filtration.

[0063] In a preferred embodiment, as Figure 1 shown, a plurality of support legs 13 are evenly distributed on the outer periphery of the bottom end of the tank body 1 for supporting the tank body 1. The support legs 13 are distributed on the outer periphery of the sewage discharge assembly 6, forming good protection for the sewage discharge assembly 6.

[0064] Backwashing working principle:

[0065] When backwashing the fiber filter, first close it. At this time, the tank body 1 is filled with water and is in a state of having water but no pressure. Then start the vibration assembly 4 to drive the fiber bundle 33 of the carpet-type filter assembly 3 to vibrate, shaking off the dirt on the fiber bundle 33. Then open the first sewage discharge valve 63, and the sewage in the tank body 1 is discharged through the first sewage discharge pipe 61; at the same time, the water in the filter tank 2 flows out reversely through the filter holes 21, and after flushing the fiber bundle 33, it is also discharged through the first sewage discharge pipe 61 to complete the first backwashing.

[0066] The design of the vibration assembly 4 is inspired by people's cleaning of blankets in daily life. For small blankets, they are directly shaken in the air by hand to shake off the dust; for large blankets, they are hung up and beaten with a stick to make them vibrate to shake off the dust. The vibration assembly 4 uses the same principle to make the fiber bundle 33 vibrate at a high speed, thus shaking off the dirt and achieving excellent cleaning effect.

[0067] After the sewage of the first backwash is drained, start the high-pressure water pump of the backwash assembly 5 to supply water, and backwash the carpet-type filter assembly 3 through the 360-degree high-pressure nozzle 51. The rotating nozzle forms a strong impact on the fiber bundle 33 to complete the second backwash. With the cooperation of the vibration assembly 4 and the backwash assembly 5, an excellent backwash effect can be achieved. At this time, both the first sewage discharge valve 63 and the second sewage discharge valve 64 are opened, and the sewage in the tank body 1 is discharged through the first sewage discharge pipe 61; the sewage in the filter tank 2 is discharged through the second sewage discharge pipe 62.

[0068] The fiber filter of the present application can complete the backwash operation with less water volume in a shorter time, which not only saves water resources, but also has a high backwash efficiency.
