Technical Field

[0001] The utility model belongs to the technical field of filters, and in particular relates to a single-chamber filter for deep treatment of reclaimed water. Background Art

[0002] Wastewater treatment is the process of purifying wastewater to ensure it meets the required quality for discharge into a water body or reuse. It is widely used in various fields, including construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscapes, healthcare, and catering, and is increasingly becoming part of everyday life. During the sewage treatment process, filters are used to remove solid particulate matter. The filtered wastewater is then treated using biochemical methods. Sewage treatment filters primarily treat wastewater for recycling. To ensure the quality of treated wastewater, the filter elements within the filters require regular replacement and maintenance.

[0003] After searching, the water treatment filter cleaning assembly with publication number CN202322815903.2 specifically discloses: a water treatment filter housing, a drain ditch and a filter element fixing frame, wherein a water inlet end is installed at the top of one side of the water treatment filter housing, a drainage end is installed at the bottom end of the water treatment filter housing, a flushing pipe is provided at the top of the water treatment filter housing, a driving motor is installed at the top of the water treatment filter housing, and a connecting shaft is installed at the bottom end of the driving motor, a brush holder is provided on both sides of the bottom end of the connecting shaft, and a disassembly structure is provided on the top of the brush holder, wherein the disassembly structure includes a connecting plate, a slider, a fixing block, a slide groove and a fastening bolt. The utility model realizes the purpose of disassembling the brush holder by rotating the fastening bolts symmetrically arranged on both sides of the bottom end of the connecting shaft, withdrawing the fastening bolts from the slider, moving the slider, and withdrawing the slider from the slide groove, so as to replace the brush and improve the replacement efficiency.

[0037] In this embodiment, there are multiple filter elements 16 , which are evenly distributed in a circle in the filter box 13 ; the tops of the multiple filter elements 16 are all connected to the connecting plate 19 .

[0038] In this embodiment, the number of filter elements 16 can be designed according to the treatment requirements of the reclaimed water to be treated, and is not specifically limited here. In practice, the number of filter elements 16 is two, three, four, six or more.

[0039] The connection between the filter elements and other components will be described by taking two filter elements 16 as an example.

[0040] Preferably, there are two filter elements 16, so there are two telescopic rods 17 and two pistons 11.

A rubber ring 18 is provided between each telescopic rod 17 and the connector 15, and a rubber ring 18 is also provided between each piston 11 and the connector 15.

[0042] Example 2

[0043] See also Figure 1 and Figure 2 Based on Example 1, the single-chamber filter for deep treatment of reclaimed water provided in this embodiment has a sealing cover 20 connected to the top of the shell 1; ventilation pipes 26 are respectively connected to the two side walls of the shell 1, and the ventilation pipes 26 are connected to the inside of the filter box 13.

[0044] During the filtration process, ventilation (e.g., air or other gas) is introduced into the filter box 13 through the ventilation tube 26 to enhance the filtration effect, promote biological reactions, and help remove pollutants that are difficult to remove through physical and chemical methods. This embodiment only protects the ventilation tube structure. The specific gas type and amount of gas introduced are designed based on the quality of the water to be treated and are not limited here.

[0045] Specifically, the sealing cover 20 is circular, and its lower surface is open to form an inner cavity structure. The size of the sealing cover 20 matches the top of the housing 1 to achieve sealing of the housing 1.

[0046] See also Figure 4 and Figure 5 In this embodiment, the inner cavity of the sealing cover 20 is provided with a fastener 21. The fastener 21 has a C-shaped structure, and there are two fasteners 21 with openings facing each other. Spiral patterns 22 are formed on both ends of the fastener 21. The two opposing spiral patterns 22 are connected by a threaded rod 23 to form a circular structure. During use, the openings of the two fasteners 21 face each other, and the threaded rod 23 axially passes through the two fasteners 21 and is threadedly connected via the spiral patterns 22. In this way, the threaded rod 23 can move the fasteners 21 on both sides of its surface toward each other during rotation.

[0047] In this embodiment, a sealing ring 25 located inside the fastener 21 is provided on the sealing cover 20 , and a third spring 24 is provided on the fastener 21 . The sealing ring 25 is connected to the fastener 21 via the third spring 24 .

[0048] See also Figure 1A fixing plate 31 is provided on the outer wall of the shell 1 , and the vent pipe 26 passes through the fixing plate 31 and communicates with the interior of the shell 1 . The fixing plate 31 can further reinforce the vent pipe 26 and increase the stability of the vent pipe 26 .

[0049] Refer to the instruction manual Figure 1-5 , only the disassembly working principle of the filter element 16 is described.

[0050] When in use, first pull the handle 30 and press the handle 30 downward, then the handle 30 will push the connecting plate 19 to move downward, and the connecting plate 19 will push the connecting piece 15, rubber ring 18 and filter element 16 downward through the telescopic rod 17 and the fourth spring 29, thereby pushing the piston 11 and the second spring 12 to retract downward. When the piston 11 and the second spring 12 move downward, the sliding of the first slide groove 5 and the first slider 6 pushes the slide member 7 to move downward, and the slide member 7 moves downward. At this time, the sliding member 10 located in the concave part of the lower part of the groove 8 will slide upward along the track of the groove 8 to the concave part of the upper part of the groove 8, and the sliding of the sliding member 10 will drive the rotating rod 9 to rotate; at the same time, the slide member 7 continues to move downward to push the first spring 4 at its bottom to retract, generating a locking force; then release the handle 30, and the slide member 7 will be pushed upward by the reset thrust of the first spring 4. Under the upward thrust of the first spring 4, The sliding member 10 slides from the upper recess of the groove 8 to the lower recess, then drives the second spring 12 and the piston 11 to move upward, and finally pushes the connecting member 15 and the filter element 16 upward, thereby pushing the filter element 16 to the outside of the filter box 13. The user pushes the filter element 16 out of the second slide groove 27 through the second slide block 28 in the connecting member 15, and realizes the removal of the filter element 16; clean the filter element 16, and after cleaning, the filter element 16 is reset through the second slide groove 27 and the second slide block 28, and then pressed by the handle 30, driving the sliding member 10 to slide from the recess at the lower part of the groove 8 along the upper right corner of the groove 8 back to the upper recess of the groove 8, and then release the handle 30, the first spring 4 is reset, pushing the slide member 7 upward, and finally the sliding member 10 is fixed by the thrust in the upper recess of the groove 8, thereby fixing the filter element 16 in the filter box 13, and completing the installation of the filter element 16.

[0051] In summary, the filter provided by the present invention can facilitate installation and removal of the filter element 16.

[0052] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
