Description

Technical Field

[0001] The utility model relates to the technical field of filtering mechanisms, in particular to a separation filtering mechanism for sewage treatment. Background Art

[0002] Filtration devices play a vital role in sewage treatment. Their main functions are: removing suspended matter and solid particles, reducing the content of harmful substances, improving treatment efficiency and water quality standards, and promoting water resource reuse and sustainable development. In summary, filtration devices play an important role in sewage treatment. Sewage treatment filtration is a complex process that requires proper design and operation according to different water quality and water volume. Effective filtration can not only improve the stability and efficiency of sewage treatment system operation, but also reduce the negative impact on the environment.

[0003] The filtering mechanism plays an important role in sewage treatment, but it still has certain problems: 1) During the sewage treatment process, the filter screen of the filtering mechanism works under high pressure and is prone to blockage, requiring frequent manual cleaning or replacement of the filter screen; 2) The filter screen is mostly arranged horizontally and intersects with the sewage to be filtered at an angle of about 90 degrees, so the filter screen will be deformed due to the large impact force; Therefore, in view of the above situation, there is an urgent need to develop a separation and filtering mechanism for sewage treatment to overcome the shortcomings in current practical applications and meet current needs. Utility Model Content

[0004] The purpose of the present utility model is to provide a separation and filtering mechanism for sewage treatment to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a separation and filtration mechanism for sewage treatment, comprising a filter plate, a collection plate located at the bottom edge of the filter plate for receiving filtered residue, a carrier plate rotatably connected to the bottom of the filter plate, a mounting frame fixed to the bottom of the carrier plate and the collection plate, and a sewer pipe installed above the filter plate;

[0006] A spiral filter is installed on the upper surface of the filter disc, a spiral drive plate is fixed in the middle position of the top of the spiral filter, blades are fixed on the inner wall of the spiral drive plate, a filter screen is detachably connected to the inner wall of the spiral filter, a spiral groove is provided at the position where the filter disc and the spiral filter are vertically aligned, and an integrally formed protrusion is provided on the top edge of the filter disc.

[0007] Preferably, the bottom of the spiral filter is hollowed out, and the bottom of the spiral filter is aligned with the spiral groove. The filter screen, spiral filter, and spiral groove are connected in sequence. Specifically, the set spiral filter can filter out impurities in the sewage, and during the rotation of the filter disc, it will cooperate with the spiral filter to use centrifugal force to slowly transfer the impurities to the outermost position until the filtered impurities fall into the collection disc through the boss.

[0008] Preferably, a groove is provided on the bottom edge of the filter disc, a limiting ring is fixed on the bottom edge of the filter disc, and a rotating shaft is fixed at the middle position of the bottom of the filter disc.

[0009] Preferably, a plurality of slag discharge pipes are provided on the bottom edge of the collecting tray. Specifically, the slag discharge pipes can discharge the filtered impurities collected in the collecting tray.

[0010] Preferably, a rotating shaft seat is provided in the middle of the supporting plate, and a drain pipe is provided at the bottom edge of the supporting plate. Specifically, the supporting plate is used to support the filter plate, keep the filter plate able to rotate freely, and receive the water filtered by the filter plate.

[0011] Preferably, the rotating shaft is rotatably connected to the rotating shaft seat. Specifically, the filter disc can be rotated around the rotating shaft by the provided rotating shaft seat.

[0012] Preferably, the collecting tray is adapted to the groove. Specifically, the provision of the groove can improve the stability between the collecting tray and the filter tray.

[0013] Compared with the prior art, the present invention provides a separation and filtration mechanism for sewage treatment, which has the following beneficial effects:

[0014] 1. It filters sewage through a spiral filter installed on the filter disc and the filter screen inside. During this process, the sewage is guided to the blades inside the spiral drive plate through the sewer pipe, which drives the spiral drive plate to rotate through the blades, and finally drives the entire filter disc to rotate counterclockwise. In this process, part of the sewage will pass through the filter screen and flow into the carrier disc, while the rest of the sewage will flow outward along the spiral path and continue to be filtered along the filter screen on the path. Large particles of impurities are filtered out and move outward along the spiral path under the action of centrifugal force during rotation. Finally, the impurities automatically fall into the collection disc, effectively extending the filter cleaning and maintenance cycle and reducing the replacement frequency.

[0015] 2. The spiral filter is equipped with a spiral drive plate, which can make the sewage spread outward evenly in a spiral shape, reducing the impact of the sewage on the filter. At the same time, since the filter is embedded in the inner side of the spiral filter, the angle of contact between the sewage and the filter is large, which can effectively avoid the deformation of the filter.

[0026] See also Figure 1-Figure 5 The utility model provides a technical solution: a separation and filtration mechanism for sewage treatment, comprising a filter disc 10, a collection disc 20 located at the bottom edge of the filter disc 10 for receiving filtered residues, a carrier disc 50 rotatably connected to the bottom of the filter disc 10, a mounting frame 30 fixed to the bottom of the carrier disc 50 and the collection disc 20, and a downpipe 40 installed above the filter disc 10;

[0027] A spiral filter 101 is installed on the upper surface of the filter disc 10, and a spiral drive plate 102 is fixedly provided at the top middle position of the spiral filter 101. Blades 103 are fixedly provided on the inner wall of the spiral drive plate 102. A filter screen 104 is detachably connected to the inner wall of the spiral filter 101. A spiral through groove 105 is provided at the position where the filter disc 10 is vertically aligned with the spiral filter 101, and an integrally formed protrusion 106 is provided on the top edge of the filter disc 10.

[0028] Preferably, the bottom of the spiral filter 101 is hollowed out, and the bottom of the spiral filter 101 is aligned with the spiral groove 105. The filter screen 104, the spiral filter 101, and the spiral groove 105 are connected in sequence. Specifically, the set spiral filter 101 can filter out impurities in the sewage, and during the rotation of the filter disc 10, it will cooperate with the spiral filter 101 to use centrifugal force to slowly transfer the impurities to the outermost position until the filtered impurities fall into the collection disc 20 through the boss 106.

[0029] Preferably, a groove 107 is formed on the bottom edge of the filter disc 10 , a limiting ring 109 is fixedly provided on the bottom edge of the filter disc 10 , and a rotating shaft 108 is fixedly provided at the middle position of the bottom of the filter disc 10 .

[0030] Preferably, a plurality of slag discharge pipes 201 are provided on the bottom edge of the collecting tray 20 . Specifically, the slag discharge pipes 201 can discharge the filtered impurities collected in the collecting tray 20 .

[0031] Preferably, a rotating shaft seat 502 is provided in the middle position of the supporting plate 50, and a drain pipe 501 is provided at the bottom edge of the supporting plate 50. Specifically, the supporting plate 50 is used to support the filter plate 20, keep the filter plate 20 able to rotate freely, and receive the water filtered by the filter plate 10.

[0032] Preferably, the rotating shaft 108 is rotatably connected to the rotating shaft seat 502 . Specifically, the provided rotating shaft seat 502 enables the filter disc 10 to rotate around the rotating shaft 108 .

[0033] Preferably, the collecting tray 20 is adapted to the groove 107 . Specifically, the provision of the groove 107 can improve the stability between the collecting tray 20 and the filter tray 10 .

[0034] Working principle: sewage is discharged through the sewer pipe 40 and guided to the blade 103. Under the impact of the water flow, the blade 103 drives the spiral drive plate 102, the spiral filter 101 and the filter disc 10 to rotate counterclockwise around the rotating shaft 108. The sewage will diffuse outward along the spiral path formed by the spiral filter 101 and the filter disc 10. In this process, it is filtered through the filter mesh 104 on the inner wall of the spiral filter 101 and flows into the supporting plate 50 below, while large particles of impurities are filtered out by the filter mesh 104. Driven by centrifugal force and water flow, the impurities will diffuse out of the filter disc 10 along the spiral path. Finally, the impurities will fall into the collection plate 20 along the protrusion 106 on the edge and be discharged through the slag discharge pipe 201, thereby automatically removing the filtered impurities and avoiding clogging of the filter mesh. The filtered water flows into the supporting plate 50 through the spiral filter 101 and the spiral groove 105, and is finally discharged from the drain pipe 501.
