Description

Technical Field

[0001] This utility model relates to the field of filter technology, and in particular to a vibrating filter for wastewater treatment. Background Technology

[0002] Sewage pipes transport urban sewage. Existing sewage pipes consist of a main sewage pipe and multiple branch sewage pipes. The branch sewage pipes connect to multiple sewage discharge points, while the main sewage pipe allows sewage from the branch sewage pipes to flow. Therefore, the main sewage pipe accumulates a large amount of sewage, resulting in high water pressure and a fast flow rate. Impurities carried in the sewage are also filtered more quickly by the filter screen installed on the main sewage pipe, causing more impurities to adhere to the surface of the filter screen. This leads to faster clogging of the filter screen, reducing the flow rate of sewage and decreasing the efficiency of sewage filtration. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a vibrating filter for wastewater treatment.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a vibrating filter for sewage treatment, comprising a filter cylinder shell and multiple filter screens, wherein multiple equidistantly arranged filter screen fixing frames are installed inside the filter cylinder shell, and fixing blocks arranged coaxially are provided inside the filter screen fixing frames, and a rotating shaft is installed through the multiple fixing blocks. The filter screens are respectively installed between the surfaces of the fixing blocks and the filter screen fixing frames, and a movable ring is elastically connected to one side of the filter screen fixing frames. One end of the rotating shaft is connected to a drive motor, and a transmission mechanism is provided between the rotating shaft and the movable ring.

[0005] Preferably, the transmission mechanism includes a movable block, which is fixedly sleeved on the surface of the rotating shaft. A wave-shaped groove with connected ends is formed along the arc surface of the movable block. A movable rod is slidably arranged inside the wave-shaped groove, and one end of the movable rod is installed inside the movable ring.

[0006] Preferably, the movable ring is provided with a plurality of sliding rods on its side. One end of each sliding rod passes through the side of the filter screen fixing frame and extends to one side thereon. A compression spring is movably sleeved on the surface of each sliding rod. The two ends of the compression spring are respectively installed on the side of the movable ring and the filter screen fixing frame.

[0007] Preferably, a stop is installed at one end of the sliding rod, and the stop contacts the side of the filter screen fixing frame.

[0008] Preferably, multiple connecting rods are installed between the fixing block and the filter fixing frame.

[0009] Preferably, the filter housing has an outlet and an inlet at each end.

[0010] Preferably, the movable annular component has multiple striking plates installed inside, and the striking plates are arranged at equal angles.

[0011] Preferably, the drive motor is installed outside the filter housing, the movable end of the drive motor penetrates the surface of the filter housing and extends into its interior, and a universal joint is connected between the movable end of the drive motor and one end of the rotating shaft.

[0012] Compared with the prior art, the present invention has the following beneficial effects: In this solution, a drive motor is used to control the rotation of the rotating shaft. The rotating shaft drives the wave-shaped grooves on multiple movable blocks to rotate synchronously and apply external force to the connecting rod. After the connecting rod is subjected to force, it drives the movable ring to reciprocate and impact the filter screen fixing frame.

[0015] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0016] like Figure 1-5The vibrating filter for wastewater treatment shown includes a filter housing 4 and multiple filter screens 14. Multiple equidistantly arranged filter screen fixing frames 12 are installed inside the filter housing 4. The filter screen fixing frames 12 have coaxially arranged fixing blocks 17 inside. Rotating shafts 8 are installed through each fixing block 17. The filter screens 14 are respectively installed between the surfaces of the fixing blocks 17 and the filter screen fixing frames 12. A movable ring 11 is elastically connected to one side of each filter screen fixing frame 12. A drive motor 18 is connected to one end of the rotating shaft 8. The drive motor 18 is installed outside the filter housing 4. The movable end of the drive motor 18 penetrates the surface of the filter housing 4 and extends into its interior. A universal joint 6 connects the movable end of the drive motor 18 and one end of the rotating shaft 8. A transmission mechanism is provided between the rotating shaft 8 and the movable ring 11. The transmission mechanism includes a movable block 2, which is fixedly sleeved on the surface of the rotating shaft 8. A wave-shaped groove 10 with its ends connected is formed along the arc surface of the movable block 2. A movable rod 9 is slidably mounted inside the wave-shaped groove 10, and one end of the movable rod 9 is installed inside the movable ring 11. After the drive motor 18 is powered on, the power of the drive motor 18 is transmitted to the rotating shaft 8 through the universal joint 6, driving the multiple movable blocks 2 on it to rotate synchronously. The wave-shaped groove 10 of the movable block 2 converts the rotational motion into the reciprocating motion of the movable rod 9 along the axial direction of the rotating shaft 8. This motion is ultimately transmitted to the movable ring 11 through the movable rod 9, causing it to periodically strike the filter screen fixing frame 12. The resulting vibration is effectively transmitted to the filter screen 14, thereby removing impurities from its surface and pores.

[0017] Multiple sliding rods 16 are installed on the side of the movable ring 11. One end of the sliding rod 16 passes through the side of the filter screen fixing frame 12 and extends to one side. A compression spring 15 is movably sleeved on the surface of the sliding rod 16. The two ends of the compression spring 15 are respectively installed on the side of the movable ring 11 and the filter screen fixing frame 12. When the movable ring 11 is subjected to force, it pushes the sliding rod 16 to slide in the filter screen fixing frame 12. When the compression spring 15 is subjected to force, its length contracts. At this time, the compression spring 15 is in an energy storage state, which can buffer the force of the movable ring 11 hitting the filter screen fixing frame 12 and convert the impact force into a continuous elastic pressure acting on the filter screen fixing frame 12, thereby achieving efficient buffering and reset.

[0018] Multiple striking plates 5 are installed inside the movable ring 11. The striking plates 5 are arranged at equal angles. The striking plates 5 move synchronously with the movable ring 11 after being subjected to force. When the movable ring 11 hits the filter screen fixing frame 12, the multiple striking plates 5 will hit the surface of the filter screen 14, increasing the force points or area of ​​the filter screen 14 and generating a uniformly distributed post-production impact force on the surface of the filter screen 14, effectively shaking off impurities attached to the inside and surface of the filter screen holes.

[0019] A stop 13 is installed at one end of the sliding rod 16. The stop 13 contacts the side of the filter screen fixing frame 12. The stop 13 is used to limit the sliding rod 16 and improve the stability of the position of the movable ring 11.

[0020] Multiple connecting rods 3 are installed between the fixing block 17 and the filter screen fixing frame 12. The multiple connecting rods 3 are used to connect and reinforce the fixing block 17 and the filter screen fixing frame 12, thereby improving the stability of the filter screen 14 installed between the fixing block 17 and the filter screen fixing frame 12.

[0021] The filter housing 4 has an outlet 1 and an inlet 7 at its two ends. The inlet 7 allows sewage to flow into the filter housing 4, and the outlet 1 allows the filtered sewage to flow out of the filter housing 4.

[0022] Working principle: Wastewater flows into the filter housing 4 from the inlet 7, and after being filtered by multiple layers of filter screens 14, clean water is discharged from the outlet 1. At the same time, the drive motor 18 works, and its power is transmitted to the rotating shaft 8 through the universal joint 6. The rotating shaft 8 drives multiple movable blocks 2 on it to rotate synchronously. The wave-shaped sliding grooves 10 opened on the surface of the movable blocks 2 convert the rotational motion of the rotating shaft 8 into the reciprocating linear motion of the movable rod 9 along the axial direction of the rotating shaft 8.

[0023] The movable rod 9 transmits its reciprocating motion to the movable ring 11, causing it to periodically strike the filter screen fixing frame 12. Simultaneously, multiple striking plates 5 inside the movable ring 11 move synchronously with it. When the movable ring 11 impacts the filter screen, these striking plates 5 directly strike the surface of the filter screen 14. This force applied to the fixing frame 12 and the filter screen 14 generates vibration waves, effectively shaking off impurities attached to the filter screen 14, thereby achieving efficient and continuous wastewater filtration and treatment.
