Description

Technical Field

[0001] This utility model relates to the field of wastewater filtration technology, and in particular to a wastewater rotating filtration structure. Background Technology

[0002] Domestic and industrial wastewater require treatment before being discharged into natural water bodies or reused to reduce their harmfulness. Wastewater treatment typically begins with preliminary filtration using screens to intercept large solid impurities such as branches and plastics, suspended solids, and large particles. Next, grit removal and conditioning are carried out, using gravity settling to separate sand, gravel, and coarse particles, which settle to the bottom. Then, flocculants are added to coagulate small particles into larger particles, which then settle. However, using flocculants to coagulate small particles is costly and slow, failing to meet the needs of scenarios requiring high treatment speeds. Furthermore, it significantly increases sludge production, raising the difficulty and cost of subsequent sludge treatment. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a wastewater rotary filtration structure that has low filtration cost, fast speed, and does not increase the amount of sludge.

[0004] This utility model is achieved using the following technical solution: a wastewater rotary filtration structure, comprising a filter, a filter mounting structure, a rotary joint, pipes, a mounting plate, an outer mounting cylinder, a bearing base, and a bearing cover. The filter mounting structure is detachably fixed to the outside of the outer mounting cylinder, and the filter is fixed within the filter mounting structure. One end of the outer mounting cylinder is sealed, and the rotary joint is connected to the other end of the outer mounting cylinder, with an inlet connected to the rotary joint. Multiple pipes are arranged in a ring inside the outer mounting cylinder, with the ends of the pipes fixed by the mounting plate, the front end of the pipes being open, and the rear end sealed. The bearing base and the bearing cover are connected by bolts to form a bearing seat. Both ends of the outer mounting cylinder are fixed within the bearing seat. Wastewater enters the rotary joint through the inlet, flows into the multiple pipes through the rotary joint, and exits after being filtered by the filter.

[0005] Furthermore, the filter is fan-shaped, with multiple filters arranged in a circle.

[0006] Furthermore, the filter mounting structure includes a threaded post, a pressure ring, and a connecting seat. The bottom end of the connecting seat penetrates the wall of the outer cylinder and is connected to the pipeline. The top end of the connecting seat is connected to the filter. The bottom end of the threaded post is fixed to the wall of the outer cylinder at equal angles by threaded engagement. The top end of the threaded post is connected to a nut by threaded engagement to fix the pressure ring. After multiple pressure rings are fixed, they are arranged into a ring to compress the filter.

[0007] Furthermore, a liquid distribution chamber is connected between the top of the connecting seat and the filter. The liquid distribution chamber is fan-shaped, with its bottom length being shorter than its top length, and its center is hollow.

[0008] Furthermore, a gear tooth is fixedly fitted on the outer side of the sealing end of the mounting outer cylinder.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: In the wastewater rotary filtration structure of this utility model, wastewater enters the rotary joint through the inlet, flows into multiple pipes through the installation plate, and enters the filter from the fan-shaped liquid distribution chamber when passing through the connecting seat. The filtered water flows out of the filter. Its filtration cost is low, the speed is fast, and it will not increase the amount of sludge or new pollutants. Attached Figure Description

It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0017] The purpose of this invention is to address the shortcomings of existing technologies by providing a rotating wastewater filtration structure.

[0018] Example 1

[0019] This embodiment provides a wastewater rotating filter structure, referring to... Figures 1-5 As shown, the system includes a filter 2, a filter mounting structure 3, a rotary joint 4, pipes 5, a mounting plate 6, an outer mounting cylinder 10, a bearing base 11, and a bearing cover 12. The filter mounting structure 3 is detachably fixed to the outside of the outer mounting cylinder 10, and the filter 2 is fixed in the filter mounting structure 3. In this embodiment, the filter 2 is a cloth filter. One end of the outer mounting cylinder 10 is sealed, and the rotary joint 4 is connected to the other end of the outer mounting cylinder 10. The rotary joint 4 is connected to an inlet 41. In this embodiment, the rotary joint 4 is a rotary joint that can rotate 360° in the prior art. Multiple pipes 5 are arranged in a ring inside the outer mounting cylinder 10. The ends of the pipes 5 are fixed by the mounting plate 6. The front end of the pipes 5 is open, and the rear end is sealed. The bearing base 11 and the bearing cover 12 are connected by bolts to form a bearing seat. Both ends of the outer mounting cylinder 10 are fixed in two bearing seats. Wastewater enters the rotary joint 4 through the inlet 41, flows into the multiple pipes 5 through the rotary joint 4, and flows out after being filtered by the filter 2. A gear tooth 13 is also fitted and fixed on the outer side of the sealing end of the outer cylinder 10. It is connected to the drive device through a chain and can be used to drive the rotation of the outer cylinder 10 and its structure.

[0020] Reference Figures 1-5 As shown, the filter 2 in this embodiment is fan-shaped, with multiple filters 2 arranged in a circle. The filter mounting structure 3 includes a threaded post 31, a pressure ring 32, and a connecting seat 34. The bottom end of the connecting seat 34 penetrates the wall of the outer cylinder 10 and is connected to the pipe 5. The top end of the connecting seat 34 is connected to the filter 2. Specifically, a liquid distribution chamber 33 is also connected between the top end of the connecting seat 34 and the filter 2. The liquid distribution chamber 33 is fan-shaped, with its bottom length shorter than its top length. The center of the liquid distribution chamber 33 is hollow. The top and sides of the filter cloth filter are connected between the threaded post 31 and the pressure ring 32, and its bottom end is connected to the liquid distribution chamber 33. The bottom end of the threaded post 31 is fixed to the wall of the outer cylinder 10 at equal angular intervals by threaded engagement. The top end of the threaded post 31 is connected to a nut by threaded engagement to fix the pressure ring 32. After the multiple pressure rings 32 are fixed, they are arranged in a circle to compress the filter 2.

[0021] This utility model discloses a wastewater rotary filtration structure. Wastewater to be treated enters the rotary joint 4 through the inlet 41, and then flows through the mounting plate 6 into multiple pipes 5. The wastewater flows from front to back within the pipes 5. Upon passing the connecting seat 34, it enters the filter 2 through the fan-shaped distribution chamber 33 for filtration. The bottom length of the distribution chamber 33 is shorter than the top length, allowing for a larger filtration area and providing more filtration space for the wastewater entering from the bottom, thus ensuring both filtration effectiveness and increased filtration speed. The filtered water flows out of the filter 2, is collected, and further processed. This filtration method is low-cost and fast, and because it does not use flocculants or other chemical substances, it does not increase sludge production or introduce new pollutants.

[0022] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
