[0002] Wastewater treatment equipment is a device that treats wastewater from domestic or industrial production. Domestic wastewater mainly consists of wastewater generated from kitchen, washing, and toilet use. The equipment aims to reduce the nitrogen, phosphorus, sulfur, and other pollutants in domestic wastewater after discharge.

[0003] Because domestic sewage discharges a lot of small particulate impurities, these impurities may accumulate in the community's drainage pipes, causing regional pipe blockages throughout the community and negatively impacting actual use. Therefore, improvements are needed. Summary of the Invention

[0004] The purpose of this utility model is to provide a new type of sewage treatment equipment, which has the advantage of connecting the sewage treatment tank to the return pipe of domestic water inside the community, for intercepting and separating small particulate impurities contained in domestic sewage, so as to filter and recover impurities in subsequent domestic sewage filtration treatment, reducing the cleaning burden in underground pipes, bringing certain beneficial effects to practical use, and solving the problems mentioned in the background art above.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A novel sewage treatment device includes a sewage treatment tank, a pretreatment box snapped onto the top of the sewage treatment tank, a locking component connected to the top of the pretreatment box, an upper cover connected to the surface of the locking component, a connecting pipe with a sealing cap fixedly connected to the top of the upper cover, a filling pipe sealed and inserted into the inside of the connecting pipe, a ceramic filter element, an activated carbon filter element, and a corrosion-resistant metal filter screen fixedly connected to the surface of the inner wall of the sewage treatment tank, a collection cylinder fixedly connected to the bottom of the sewage treatment tank, a one-way switch plate rotatably connected to the inner wall of the collection cylinder via a pin with a torsion spring, and the one-way switch plate is located at the bottom of the ceramic filter element, the activated carbon filter element, and the corrosion-resistant metal filter screen, a drain pipe fixedly connected to the left side of the sewage treatment tank, and a discharge pipe fixedly connected to the bottom of the collection cylinder.

[0006] Preferably, the locking assembly includes a magnetic locking plate and a magnetic locking groove. The magnetic locking plate is fixedly connected to the bottom of the upper cover, and the magnetic locking groove is opened on the top of the pretreatment box. The inner wall of the magnetic locking groove and the surface of the magnetic locking plate are magnetically engaged and adapted to each other.

[0007] Preferably, the number of connecting tubes is at least four, and the four connecting tubes are evenly distributed at the top circumferential direction of the upper cover.

[0008] Preferably, the main body of the pretreatment box is a sealed circular box, and an annular barrier sleeve is fixedly connected to the inner wall of the sealed circular box. A drain outlet is provided on the sealed circular box near the middle of its inner wall. A sealing filter plate is rotatably connected to the inner wall of the drain outlet through a bearing, and the sealing filter plate is located inside the annular barrier sleeve. The inner wall of the anti-corrosion metal filter sleeve and the inner wall of the drain outlet are connected.

[0009] Preferably, the inner wall of the filling pipe is rotatably connected to a buffer baffle via a pin with a torsion spring, a baffle plate is fixedly connected to the right side of the inner wall of the filling pipe, and a flow-relief plate is fixedly connected to the side of the inner wall of the sewage treatment tank.

[0010] Preferably, an annular groove plate is fixedly connected to the top of the ceramic filter element, and the inner wall of the annular groove plate is formed into a smooth arc-shaped surface.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In this utility model, the filling pipe is sealed and connected to the sewage treatment tank via a connecting pipe at the top. The upper pipe of the filling pipe is connected to the drainage pipe in the household. The sewage discharged will first impact the buffer baffle in the filling pipe for buffering and unloading. The baffle plate set below the buffer baffle provides unloading support at the bottom, and multiple diversion and unloading plates can buffer the sewage to flow downwards. It enters the interior of the pretreatment tank through the connecting pipe. The annular barrier sleeve in the pretreatment tank receives the falling sewage impurities. The sewage enters the interior of the pretreatment tank through the high-level annular barrier sleeve, and then flows downwards through the sealed filter plate and into the sewage treatment tank through the drain outlet. Large particles of impurities are trapped between the pretreatment tank and the annular barrier sleeve, which can complete the pretreatment of sewage, trapping large particles of impurities and buffering and unloading the impact force.

[0014] In this invention, the sewage inside the sewage treatment tank passes through a corrosion-resistant metal filter sleeve, an activated carbon filter element, and a ceramic filter element sequentially from the inside out, achieving multi-layer filtration and interception of the sewage. A collection cylinder is located below the corrosion-resistant metal filter sleeve, activated carbon filter element, and ceramic filter element to collect impurities. When a large amount of impurities accumulates, downward pressure is applied, causing a one-way switch plate to move downwards, allowing the impurities to enter the collection cylinder for temporary storage. The impurities are then discharged through a discharge pipe. The included drain pipe allows for the discharge of the intercepted sewage, preventing pipe blockage in residential areas and facilitating the separation of impurities and water flow, as well as the convenient cleaning of subsequent impurities.

[0024] Furthermore, the locking assembly includes a magnetic locking plate 13 and a magnetic locking groove 14. The magnetic locking plate 13 is fixedly connected to the bottom of the upper cover 3, and the magnetic locking groove 14 is opened on the top of the pretreatment box 2. The inner wall of the magnetic locking groove 14 and the surface of the magnetic locking plate 13 are magnetically engaged and adapted. With the setting of the magnetic locking plate 13 and the magnetic locking groove 14, the upper cover 3 can be easily installed and removed from the pretreatment box 2.

[0025] Furthermore, the number of connecting pipes 4 is at least four, and the four connecting pipes 4 are evenly distributed on the top of the circumferential direction of the upper cover 3. The four connecting pipes 4 can connect to multiple pipes at different locations.

[0026] Furthermore, an annular groove plate 21 is fixedly connected to the top of the ceramic filter element 6. The inner wall of the annular groove plate 21 is opened into an arc-shaped smooth surface. With the setting of the annular groove plate 21, the sewage from the flushing can be guided and discharged, and the top of the ceramic filter element 6 can be protected.

[0027] Furthermore, a stop limiting plate 22 is fixedly connected to the top of the collection cylinder 9. The bottom of the stop limiting plate 22 abuts against the top of the one-way switch plate 10, and the stop limiting plate 22 is located directly above the one-way switch plate 10. The stop limiting plate 22 can be used to limit and block the one-way switch plate 10 in one direction, preventing the one-way switch plate 10 from opening upwards.

[0028] Example 2, please refer to Figures 1 to 6The difference between this embodiment and Embodiment 1 is that the main body of the pretreatment tank 2 is a sealed circular box. An annular barrier sleeve 15 is fixedly connected to the inner wall of the sealed circular box. A drain outlet 16 is provided near the middle of the inner wall of the sealed circular box. A sealed filter screen plate 17 is rotatably connected to the inner wall of the drain outlet 16 through a bearing. The sealed filter screen plate 17 is located inside the annular barrier sleeve 15. The inner wall of the anti-corrosion metal filter screen sleeve 8 is connected to the inner wall of the drain outlet 16. The annular barrier sleeve 15 in the pretreatment tank 2 receives the falling sewage impurities. The sewage above enters the interior of the pretreatment tank 2 through the high-level annular barrier sleeve 15, and then flows downward through the sealed filter screen plate 17 and drain outlet 16 into the sewage treatment tank 1. Large particles of impurities are trapped between the pretreatment tank 2 and the annular barrier sleeve 15.

[0029] Furthermore, the inner wall of the filling pipe 5 is rotatably connected to a buffer baffle 18 via a pin with a torsion spring. A baffle plate 19 is fixedly connected to the right side of the inner wall of the filling pipe 5. A flow-reducing and stress-relieving plate 20 is fixedly connected to the side of the inner wall of the sewage treatment tank 1. The baffle plate 19, located below the buffer baffle 18, provides stress relief and support to the bottom. Multiple flow-reducing and stress-relieving plates 20 can buffer and discharge sewage downwards.

[0030] Working Principle: In this new type of sewage treatment equipment, the sewage treatment tank 1 is the main wastewater filtration unit. A connecting pipe 4 above the upper cover 3 is used to seal the filling pipe 5. The upper part of the filling pipe 5 is connected to the drain pipe 11 in a household. The discharged sewage first impacts the buffer baffle 18 in the filling pipe 5 for buffering and stress relief. A baffle plate 19 below the buffer baffle 18 provides stress relief support at the bottom, and multiple flow-reducing plates 20 buffer and discharge the sewage downwards. The sewage then enters the pretreatment tank 2 through the connecting pipe 4. The annular baffle sleeve 15 in the pretreatment tank 2 catches falling sewage impurities. The sewage then passes through the high-level annular baffle sleeve 15 into the pretreatment tank 2, passes through the sealed filter plate 17, and flows downwards through the drain outlet 16 into the sewage treatment tank 1. Large particles... Impurities are trapped between the pretreatment tank 2 and the annular barrier sleeve 15. The sewage entering the sewage treatment tank 1 passes through the anti-corrosion metal filter sleeve 8, activated carbon filter element 7, and ceramic filter element 6 from the inside to the outside, completing multi-layer filtration and interception of sewage. A collection cylinder 9 is set below the anti-corrosion metal filter sleeve 8, activated carbon filter element 7, and ceramic filter element 6 to collect impurities. When there is a large accumulation of impurities, pressure is applied downward to drive the one-way switch plate 10 downward, allowing the impurities to enter the collection cylinder 9 for temporary storage. The impurities are then discharged through the discharge pipe 12. The drainage pipe 11 can discharge the intercepted sewage, which can avoid pipe blockage in residential areas and facilitates the separation of impurities and water flow as well as the subsequent cleaning of impurities. This ensures the initial sewage treatment effect that is suitable for small areas in residential buildings and prevents pipe blockage.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
