[0002] In the field of wastewater treatment, traditional filtration equipment often faces problems such as easy clogging of filter cartridges, decreased filtration efficiency, and high maintenance costs. Specifically, when wastewater enters the filtration equipment, although the filter cartridge can effectively intercept impurities, over time, a large amount of impurities tend to accumulate on the outer wall of the filter cartridge, leading to clogging and affecting the filtration efficiency and effluent quality of the equipment. To solve this problem, it is usually necessary to shut down the equipment periodically for manual cleaning, which not only increases maintenance costs but also affects the continuous operation capability of the equipment.

[0038] The present invention is illustrated below with specific embodiments, but these are not intended to limit the scope of the invention.

[0039] Example 1

[0040] like Figures 1-6 As shown in this embodiment, a filtration device for sewage treatment is provided, including a filter cartridge 1, which has an inlet pipe 101 and an outlet pipe 102. A filter element 2 is installed inside the filter cartridge 1, and filter holes for filtering sewage are uniformly opened on the surface of the filter element 2. An annular gap communicating with the inlet pipe 101 is provided between the filter element 2 and the interior of the filter cartridge 1. A cleaning component 3 for cleaning the inner wall of the filter element 2 is provided in the annular gap, and the inner cavity of the filter element 2 is communicating with the outlet pipe 102.

[0041] Work process:

[0042] When the wastewater treatment equipment starts working, wastewater is first introduced into the interior of filter cartridge 1 through inlet pipe 101. Subsequently, the wastewater enters the annular gap formed between filter element 2 and the inner wall of filter cartridge 1. Within this annular gap, the wastewater is blocked by filter element 2, with impurities being intercepted by the filter pores on the surface of filter element 2, while clean water continues to enter the inner cavity of filter element 2 through the filter pores. As clean water accumulates in the inner cavity of filter element 2, it is eventually discharged through outlet pipe 102, thus achieving wastewater filtration.

[0043] During the filtration process, the cleaning component 3 will periodically or according to the accumulation of impurities on the inner wall of the filter element 2 to clean the inner wall of the filter element 2, preventing clogging and ensuring stable filtration efficiency. In this way, the wastewater treatment equipment can continuously and efficiently treat wastewater, contributing to environmental protection and water resource reuse.

[0044] A top cover 104 is provided above the filter cartridge 1, and the water outlet pipe 102 is fixed in the middle of the top cover 104.

[0045] The upper end of the filter element 2 is fixed with an outwardly folded ring plate 201, and a second ring groove 8 is provided at the connection between the upper end cover 104 and the filter cartridge 1. The ring plate 201 is clamped inside the second ring groove 8.

[0046] Example 2

[0047] like Figures 1-5 As shown, based on Embodiment 1, in order to clean the outer wall of the filter element 2, the cleaning component 3 includes a lower turntable 301 and an upper turntable 302. The lower turntable 301 and the upper turntable 302 are respectively disposed at the lower end and the upper end of the inner cavity of the filter cartridge 1. Multiple cleaning plates 303 are evenly distributed between the lower turntable 301 and the upper turntable 302, and one side of the cleaning plate 303 is in contact with the outer wall of the filter element 2. The design of the cleaning plate 303 can ensure the comprehensive cleaning of the outer wall of the filter element 2. Among them, a rotating rod 304 is fixed at the center of the lower turntable 301, and the lower end of the rotating rod 304 extends to the outside of the filter cartridge 1 and is connected to a rotating handle 305.

[0048] A brush is provided on the side of the cleaning plate 303 that is in contact with the outer wall of the filter element 2.

[0049] The cleaning plate 303 is arranged in a spiral shape.

[0050] A lower end cover 103 is provided below the filter cartridge 1, and a rotating rod 304 passes through the center of the lower end cover 103 and extends to the outside.

[0051] A sealing ring 4 is provided at the connection between the rotating rod 304 and the lower end cover 103.

[0052] Work process:

[0053] When cleaning the inner wall of filter element 2 is required, the operator holds the handle and manually rotates the rotating rod 304. The rotation of the rotating rod 304 causes the lower rotating disk 301 and the upper rotating disk 302 to rotate synchronously, which in turn causes the cleaning plate 303 between them to move in a spiral trajectory on the outer wall of filter element 2. The brush on one side of the cleaning plate 303 is in close contact with the outer wall of filter element 2, and the friction of the bristles effectively removes the impurities attached to the outer wall of filter element 2.

[0054] Because the cleaning plates 303 are spirally arranged, they can gradually cover the entire outer wall of the filter element 2 during rotation, ensuring thorough cleaning. At the same time, the presence of the sealing ring 4 ensures that the rotating rod 304 does not cause sewage leakage inside the filter cartridge 1 during rotation, maintaining the equipment's sealing and safety.

[0055] Example 3

[0056] like Figures 1-4 As shown, based on Embodiment 2, in order to better discharge impurities within the annular gap, the lower end cover 103 is conical in shape, and a drain pipe 5 for discharging impurities is provided on the lower end cover 103, with a valve 6 installed on the drain pipe 5. A first annular groove 7 is provided at the connection between the lower end cover 103 and the filter cartridge 1, and the lower turntable 301 is rotatably connected inside the first annular groove 7.

[0057] Work process:

[0058] During the operation of the wastewater treatment equipment, after the wastewater is filtered by filter element 2, impurities are trapped in the annular gap. Over time, the impurities gradually accumulate in the annular gap. When the operator opens valve 6 on the drain pipe 5, the lower end cap 103, being conical in shape, helps to gather the impurities deposited in the annular gap towards the center. As valve 6 is opened, the impurities are discharged outside the equipment through the drain pipe 5 under the influence of gravity and any possible slight disturbance.

[0059] During the drainage process, the lower turntable 301 and the cleaning assembly 3 rotate to help loosen impurities adhering to the outer wall of the filter element 2 and allow them to fall into the central area of ​​the lower end cover 103. Once drainage is complete, valve 6 is closed, and the equipment can continue to operate normally.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate and not limit the technical solutions of this utility model. Although this utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to this utility model without departing from the spirit and scope of this utility model. Any modifications or partial substitutions should be covered within the scope of the claims of this utility model.
