Description

Technical Field

[0001] This utility model relates to the technical field of sewage treatment equipment, specifically a domestic sewage treatment and reuse device. Background Technology

[0002] With the increasing prominence of water scarcity, the recycling and reuse of domestic sewage has become an important way to conserve water resources.

[0003] Existing domestic wastewater treatment devices often face the problem of filter clogging during the pretreatment stage. Traditional filters are mostly fixed and can be cleared by scraping with a scraper. However, during the clearing process, it is not possible to store a large amount of wastewater to impact and loosen the blockage. Therefore, those skilled in the art have provided a domestic wastewater treatment and reuse device to solve the aforementioned problems. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a domestic sewage treatment and reuse device.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A domestic sewage treatment and reuse device, comprising:

[0007] The main body of the device has a sloped side, and a waste pool is provided below the sloped side.

[0008] Sewage pipes are used to guide domestic sewage to the inclined plane;

[0009] A filter screen, located below the inclined surface, is used to filter impurities from domestic sewage.

[0010] There are two side plates, symmetrically arranged, one on each side of the inclined surface;

[0011] A rotating shaft is rotatably disposed between the two side plates, and the outlet end of the sewage pipe is located between the rotating shaft and the inclined surface;

[0012] The scraper is set at equal angles on the side of the rotating shaft, and its length is equal to the distance between the two side plates. The movable side of the scraper contacts the side edge of the filter screen away from the debris pool.

[0013] The two side plates, the two adjacent scrapers, and the rotating shaft form a temporary storage space for sewage. When the temporary storage space rotates toward the filter screen, the accumulated sewage impacts the edge of the filter screen, and the scrapers scrape the surface of the filter screen.

[0014] Preferably, an elastic scraper is provided on the side of the scraper away from the rotating shaft, and the elastic scraper is in interference contact with the surface of the filter screen.

[0015] Preferably, the outlet end of the sewage pipe is inclined toward the rotating shaft, and the horizontal distance between the sewage landing point and the rotating shaft is 1 / 3 to 1 / 2 of the length of the scraper.

[0016] Preferably, the filter screen is inclined at 0° to 15° to the horizontal plane, and the end of the filter screen closer to the debris pool is lower than the end farther away from the debris pool.

[0017] Preferably, a motor is provided at one end of the rotating shaft, and the rotating shaft rotates in one direction only.

[0018] In summary, this utility model has the following beneficial technical effects:

[0019] The two side plates, the two adjacent scrapers, and the rotating shaft form a temporary storage space for sewage. When the amount of water stored is too large, the center of gravity tilts towards the inclined plane, and the temporary storage space rotates towards the filter screen. A large amount of accumulated sewage flows out, utilizing the gravitational potential energy of the sewage. The impact of the sewage can loosen the stubborn impurities attached to the filter screen. Then the scraper follows closely to sweep, forming a dual cleaning effect of impact and scraping, which greatly improves the self-cleaning ability of the filter screen and effectively solves the problems of traditional filter screens being easy to clog and requiring frequent manual cleaning.

[0025] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0026] A domestic sewage treatment and reuse device, referring to Figure 1-3 ,include:

[0027] The main body of the device 1 has one side sloped to allow wastewater to flow naturally under gravity. A debris pool is located below the slope for easy and unified cleaning, preventing the accumulation of impurities that could clog the device. The main body of the device 1 contains multi-stage wastewater treatment tanks, and the treated wastewater can be reused; details will not be elaborated here.

[0028] The sewage pipe 11 is used to guide domestic sewage to the inclined surface. The outlet end of the sewage pipe 11 is inclined towards the rotating shaft 3. The horizontal distance between the sewage landing point and the rotating shaft 3 is 1 / 3 to 1 / 2 of the length of the scraper 4. This inclined design and distance control can make the sewage spray out to form a directional impact force. On the one hand, it can provide power for the rotation of the rotating shaft 3 and reduce energy consumption. On the other hand, it can ensure that the sewage evenly covers the surface of the filter screen 12 and improve the filtration efficiency.

[0029] The filter screen 12 is located below the slope and is used to filter debris from domestic sewage. The filter screen 12 is inclined at 0° to 30° with the horizontal plane, and the end of the filter screen 12 closer to the debris pool is lower than the end farther away from the debris pool. The precise control of the inclination angle not only ensures the maximization of the filtration area, but also allows the filtered debris to slide naturally into the debris pool by gravity, reducing the probability of impurities adhering to the filter screen 12.

[0030] There are two side plates 2, which are symmetrically arranged on both sides of the inclined surface. The side plates 2 not only play a role in sealing and supporting, but also form a sewage diversion channel together with the inclined surface and the filter screen 12 to prevent sewage from overflowing and ensure the sealing and safety of the sewage treatment process.

[0031] The rotating shaft 3 is rotatably positioned between the two side plates 2, and the outlet end of the sewage pipe 11 is located between the rotating shaft 3 and the inclined plane.

[0032] The scraper 4 is set at equal angles on the side of the rotating shaft 3. Its length is equal to the distance between the two side plates 2, and the movable side of the scraper 4 contacts the side edge of the filter screen 12 away from the debris pool.

[0033] The two side plates 2, the two adjacent scrapers 4, and the rotating shaft 3 form a temporary storage space for sewage, which can store a certain amount of water. When the stored water is too much, the center of gravity tilts towards the inclined plane, and the temporary storage space rotates towards the filter screen 12. The accumulated sewage flows out and impacts the edge of the filter screen 12. The scraper 4 scrapes the surface of the filter screen 12. This structural design cleverly utilizes the gravitational potential energy of the sewage. The impact of the sewage can loosen the stubborn impurities attached to the filter screen 12. Then the scraper 4 follows up with a sweeping motion, forming a dual cleaning effect of impact and scraping, which greatly improves the self-cleaning ability of the filter screen 12 and effectively solves the problem that traditional filter screens 12 are prone to clogging and require frequent manual cleaning.

[0034] An elastic scraper is provided on the side of the scraper 4 away from the rotating shaft 3, and the elastic scraper makes interference contact with the surface of the filter screen 12. The elastic scraper is made of wear-resistant rubber, and the interference contact design ensures that the scraper fits tightly with the surface of the filter screen 12. Even if the filter screen 12 is slightly deformed, the cleaning effect can still be guaranteed. At the same time, the elastic material has a cushioning effect, avoiding hard contact that will cause wear to the filter screen 12 and extending the service life of the filter screen 12. In addition, the elastic deformation of the scraper can also adapt to the tilt angle of the filter screen 12, ensuring that there are no dead corners in the scraping process.

[0035] A motor is installed at one end of the rotating shaft 3. The motor provides a stable power source as a backup to prevent the scraper 4 from being unable to easily scrape the filter screen 12. The rotating shaft 3 rotates in one direction, which can be achieved by a ratchet and a pawl, to prevent the scraper 4 and the rotating shaft 3 from reversing due to external forces.

[0036] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
