Description

Technical Field

[0001] This utility model relates to the field of filtration device technology, and in particular to a filtration device for treating domestic sewage. Background Technology

[0002] Sewage filtration is an important part of the sewage treatment process. It removes pollutants such as suspended solids, organic matter, and pathogens from sewage through physical, chemical, and biological methods to meet discharge standards or reuse requirements.

[0003] The existing announcement number CN221579963U, entitled "A Filter Tank for Treating Domestic Sewage," includes an outer tank mechanism, which includes an outer protective tank. Inside the outer tank mechanism is an inner tank mechanism to prevent leakage of internal sewage. The inner tank mechanism includes an inner protective tank and a collection mechanism for collecting hair and flocculent matter. The collection mechanism includes a sealing plate snapped onto the top of the outer protective tank. A pull rod is fixedly connected to the top of the sealing plate, and a water inlet pipe is connected to the top of the sealing plate. A filter plate (a) is fixedly connected to the bottom of the sealing plate, and a collection component for collecting hair and flocculent matter is provided at the bottom of the sealing plate. Filter cotton is fixedly installed inside the inner protective tank, and an activated carbon plate is fixedly installed at the bottom of the filter cotton. A water outlet pipe is fixedly connected to the bottom of the inner protective tank. This device has the advantages of being able to collect hair and flocculent matter from sewage, reducing the probability of filter plate clogging, and ensuring the filtration effect of the device.

[0004] However, when filtering and removing domestic sewage as described above, the flowing domestic sewage passes through the filter plate to remove impurities, but the impurities filtered by the filter plate remain on the filter plate. The lack of cleaning components leads to excessive accumulation in the later stages, which affects the sewage flow rate and the sewage filtration effect. Utility Model Content

[0005] This utility model solves the problems in related technologies and proposes a filtration device for domestic sewage treatment.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a filtration device for domestic sewage treatment, including a filter element, a cleaning element, an inner filter cylinder and an outer filter cylinder. The filter element includes a filter shell, with a drain pipe horizontally connected to the bottom of the outer circumference of the filter shell, and a cap threadedly assembled at the bottom end of the filter shell. The cleaning element includes a cover plate, which is fixed to the top of the filter shell, and an inlet pipe is vertically fixed through the center of the top surface of the cover plate. Two screw rings are vertically arranged at the same center on the bottom surface of the cover plate, and the tops of the two screw rings are fixed to the bottom surface of the cover plate. An inner filter cylinder and an outer filter cylinder are vertically arranged below the cover plate, and screw shells are vertically fixed at the tops of both the inner and outer filter cylinders. The screw shells on the inner and outer filter cylinders are respectively threadedly assembled in the two screw rings.

[0007] As a preferred embodiment, both spiral rings have horizontally arranged rotating rings inside, and the rotating rings rotate through the top surface of the cover plate.

[0008] As a preferred embodiment, a scraper is vertically fixed on the bottom surface of the rotating ring, and a toothed ring is horizontally fixed on the outside of the rotating ring.

[0009] As a preferred embodiment, a first motor is vertically fixed on one side of the top surface of the cover, and a first drive gear is horizontally fixed at the output end of the first motor, and the first drive gear meshes with the gear ring on the inner rotating ring.

[0010] As a preferred embodiment, a second motor is vertically fixed on the outer wall of the filter housing, and a second drive gear is horizontally fixed at the output end of the second motor, and the second drive gear meshes with the gear ring on the outer rotating ring.

[0011] As a preferred embodiment, springs are vertically fixed on both sides of the outer wall of the filter housing, and a bracket is vertically fixed at the bottom of the springs.

[0012] As a preferred option, a vibration motor is vertically fixed on the outer wall of the filter housing.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: During use, the valves on the inlet and outlet pipes are opened to guide domestic sewage into the filter housing. The domestic sewage enters the inner filter cartridge to filter and remove impurities. After being filtered and removed by the outer filter cartridge, the sewage is discharged through the outlet pipe. When cleaning the impurities inside the inner and outer filter cartridges, the valve on the inlet pipe is closed and the sealing thread is disassembled. The impurities inside the inner and outer filter cartridges are discharged from the filter housing under the action of gravity. Thus, the impurities inside the inner and outer filter cartridges can be cleaned, avoiding excessive accumulation in the later stage that affects the sewage flow rate and the sewage filtration effect, thereby improving the sewage filtration effect.

[0026] like Figures 1 to 5As shown, a filtration device for treating domestic sewage includes a filter element 1, a cleaning element 2, an inner filter cylinder 3, and an outer filter cylinder 4. The filter element 1 includes a filter shell 11, with a drain pipe 12 horizontally connected to the bottom of the outer circumference of the filter shell 11, and a cap 13 threaded onto the bottom end of the filter shell 11. The cleaning element 2 includes a cover plate 21, which is fixed to the top of the filter shell 11, and an inlet pipe 25 is vertically fixed through the center of the top surface of the cover plate 21. Two screw rings 22 are vertically arranged at the same center on the bottom surface of the cover plate 21, and the tops of the two screw rings 22 are fixed to the bottom surface of the cover plate 21. The inner filter cylinder 3 and the outer filter cylinder 4 are vertically arranged below the cover plate 21, and screw shells 5 are vertically fixed to the tops of both the inner filter cylinder 3 and the outer filter cylinder 4. The screw housings 5 ​​on the outer filter cartridge 4 are respectively threaded into two screw rings 22. During use, the valves on the inlet pipe 25 and the drain pipe 12 are opened to guide domestic sewage into the filter housing 11. The domestic sewage enters the inner filter cartridge 3 for filtration to remove impurities. After being filtered by the outer filter cartridge 4, the sewage is discharged through the drain pipe 12. When cleaning the impurities inside the inner filter cartridge 3 and the outer filter cartridge 4, the valve on the inlet pipe 25 is closed and the screw cap 13 is unscrewed. The impurities inside the inner filter cartridge 3 and the outer filter cartridge 4 are discharged from the filter housing 11 under the action of gravity. Thus, the impurities inside the inner filter cartridge 3 and the outer filter cartridge 4 can be cleaned, avoiding excessive accumulation in the later stage that affects the sewage flow rate and the sewage filtration effect, thereby improving the sewage filtration effect.

[0027] In one embodiment, such as Figure 4 and 5 As shown, each of the two spiral rings 22 has a horizontally arranged rotating ring 26 inside, and the rotating ring 26 rotates through the top surface of the cover plate 21. A scraper 28 is vertically fixed on the bottom surface of the rotating ring 26, and a toothed ring 27 is horizontally fixed on the outside of the rotating ring 26. A first motor 23 is vertically fixed on one side of the top surface of the cover 13, and a first drive gear 24 is horizontally fixed at the output end of the first motor 23. The first drive gear 24 meshes with the toothed ring 27 on the inner rotating ring 26. A second motor 17 is vertically fixed on the outer wall of the filter shell 11, and the output end of the second motor 17 is horizontally fixed. A second drive gear 18 is fixed and meshes with a toothed ring 27 on the outer rotating ring 26. During use, in order to prevent impurities from clogging the inner filter cartridge 3 and the outer filter cartridge 4, the first motor 23 and the second motor 17 are started to drive the first drive gear 24 and the second drive gear 18 to rotate. The meshing drives the toothed ring 27 on the rotating ring 26 to rotate. The rotating ring 26 rotates and uses the scraper 28 to scrape away the impurities adhering to the inner wall of the inner filter cartridge 3 and the outer filter cartridge 4, effectively ensuring the effectiveness of impurity removal and the filtration effect of the inner filter cartridge 3 and the outer filter cartridge 4.

[0028] In one embodiment, such as Figure 2 and 3As shown, springs 15 are vertically fixed on both sides of the outer wall of the filter housing 11, and a bracket 14 is vertically fixed at the bottom of the springs 15. A vibration motor 16 is vertically fixed on the outer wall of the filter housing 11. When the vibration motor 16 is started, it causes the bracket 14 and spring 15 on the filter housing 11 to deform and shake, which helps to quickly shake off the internal impurities during the discharge process.

[0029] In this embodiment, during use, the valves on the inlet pipe 25 and the drain pipe 12 are opened to guide domestic sewage into the filter housing 11. The domestic sewage enters the inner filter cylinder 3 to filter and remove impurities. After the domestic sewage is filtered and removed by the outer filter cylinder 4, the sewage is discharged through the drain pipe 12. When cleaning the impurities inside the inner filter cylinder 3 and the outer filter cylinder 4, the valve on the inlet pipe 25 is closed, and the threads of the cap 13 are unscrewed. The impurities inside the inner filter cylinder 3 and the outer filter cylinder 4 are discharged from the filter housing 11 under the action of gravity.

[0030] The above are preferred embodiments of this utility model. Those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above. Any obvious improvements, substitutions or modifications made by those skilled in the art based on this utility model shall fall within the protection scope of this utility model.
