Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and more specifically, to a buried domestic wastewater MBR membrane processor. Background Technology

[0002] Domestic sewage is wastewater discharged from residents' daily lives, mainly originating from residential and public buildings such as houses, government offices, schools, hospitals, shops, public places, and industrial enterprise toilets. When discharging sewage, a sewage treatment device needs to be buried underground. For example, the patent with prior art announcement number CN213037489U discloses a buried domestic sewage MBR membrane processor. Water flows into the flushing component through the inlet pipe. After entering, it is diverted through the diversion pipe, and the sewage flows out from multiple flushing heads. The flushing heads are aligned with the MBR flat sheet membrane, and the surface deposits of the MBR flat sheet membrane are flushed by the flow of sewage. As sewage is injected, the first treatment chamber gradually overflows. When the sewage volume is too large, the control valve can be opened, and the sewage can flow into the second treatment chamber, so that the first and second treatment chambers can be treated simultaneously. The sewage is filtered by the MBR flat sheet membrane, and the sludge will remain in the first and second treatment chambers. The treated sewage will enter the drainage chamber and be discharged through the drainage chamber.

[0003] When the above-mentioned device is in use, if the sewage volume is large, the delivery conduit can be opened to allow the sewage to flow into the second treatment chamber. The sewage is then treated together by the first and second treatment chambers. If the sewage volume is small, excess MBR membranes can be sealed to ensure full utilization of the MBR membranes. However, it cannot control the number of MBR membranes installed according to the type of domestic sewage, thus limiting the applicability of the MBR membrane processor. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an underground domestic sewage MBR membrane processor. The technical problem to be solved by the present invention is: how to conveniently adjust and control the number of MBR membrane plates installed according to the type of sewage.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a buried domestic sewage MBR membrane processor, including a sewage processor shell, an outlet pipe is provided in the middle of the lower end of the sewage processor shell, a first limiting plate, a second limiting plate and a third limiting plate are provided on both sides of the outlet pipe inside the sewage processor shell, an MBR membrane plate is provided between the first limiting plate and the second limiting plate, and a unidirectional MBR membrane is provided on the end face of the MBR membrane plate;

[0006] A limiting pressure plate is provided on one side of the second limiting plate, and a supporting slide rod is provided on one side of the outer end face of the limiting pressure plate. A limiting ring is provided on the outer end face of the supporting slide rod between the second limiting plate and the third limiting plate, and a supporting spring is provided on one side of the limiting ring on the outer end face of the supporting slide rod.

[0007] In a preferred embodiment, the upper end of the sewage treatment unit housing is provided with a sealing cover, and a locking bolt is provided at the connection between the sewage treatment unit housing and the sealing cover;

[0008] The upper side of one end of the sewage processor housing is provided with a first water inlet pipe, and the outer end face of the sewage processor housing is provided with a second water inlet pipe on the side away from the first water inlet pipe.

[0009] In a preferred embodiment, a first drain outlet and a second drain outlet are provided on both sides of the lower end of the sewage treatment unit casing;

[0010] Both the first and second drain outlets have sealing sleeves in the middle, and a servo motor is provided on the outside of the sealing sleeves.

[0011] In a preferred embodiment, the output shaft of the servo motor passes through the end face of the sealing sleeve and extends into the interior of the sealing sleeve, and the output shaft of the servo motor is provided with a sealing rotating roller inside the sealing sleeve.

[0012] In a preferred embodiment, a square drain trough is provided in the middle of the sealed rotating roller, and limiting baffles are provided inside the sewage treatment unit housing on both sides near the first and second water inlet pipes.

[0013] In a preferred embodiment, one end of the support slide rod is provided with a connecting plate, and the middle of the outer end of the connecting plate is provided with an adjusting pull plate. The support slide rod is sequentially arranged through the end faces of the second limiting plate and the third limiting plate.

[0014] In a preferred embodiment, the servo motor is electrically connected to an external control device, the inner end face of the square sewage trough in the main viewing direction is coplanar with the inner end faces of the first sewage outlet and the second sewage outlet in the main viewing direction, and a water guide groove is reserved at the lower end of the limiting baffle.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] In practical use, by adjusting the third limiting plate, connecting plate, adjusting pull plate, supporting spring, limiting ring, and supporting slide rod in their corresponding configurations, the adjusting pull plate can be moved to one side. This adjustment pull plate, through the connecting plate and supporting slide rod, will move the limiting pressure plate to one side, facilitating the installation of the MBR membrane plate. After the MBR membrane plate is installed, the supporting spring will push against the limiting ring and limiting pressure plate to return to their original positions, allowing the limiting pressure plate to hold the MBR membrane plate in place. This effectively increases the convenience and stability of MBR membrane plate installation and allows for adjustment and control of the number of MBR membrane plates installed according to the composition of the wastewater to be treated.

However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, they are provided so that the description of this disclosure will be more complete and fully convey the concept of the exemplary embodiments to those skilled in the art. The drawings are merely illustrative of this disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and therefore repeated descriptions of them will be omitted.

[0024] Furthermore, the described features, structures, or characteristics can be combined in any suitable manner in one or more exemplary embodiments. Numerous specific details are provided in the following description to give a full understanding of exemplary embodiments of this disclosure. However, those skilled in the art will recognize that the technical solutions of this disclosure can be practiced with one or more of the specific details omitted, or other methods, components, steps, etc., can be employed. In other instances, well-known structures, methods, implementations, or operations are not shown or described in detail to avoid obscuring various aspects of this disclosure.

[0025] This utility model provides a buried domestic sewage MBR membrane processor, such as Figure 1 , 2 As shown in Figure 3, the system includes a sewage treatment unit housing 1, with a water outlet pipe 14 provided in the middle of the lower end of the sewage treatment unit housing 1, and a sealing cover 2 provided in the upper end of the sewage treatment unit housing 1.

[0026] The connection between the sewage processor housing 1 and the sealing cover 2 is provided with a locking bolt 3, which can be used to easily install and fix the sealing cover 2. A first water inlet pipe 4 is provided on the upper side of one end of the sewage processor housing 1, and a second water inlet pipe 5 is provided on the outer end face of the sewage processor housing 1 away from the first water inlet pipe 4. The operator can connect the domestic sewage drain pipe to the first water inlet pipe 4 and the second water inlet pipe 5, so that domestic sewage can be easily introduced into the interior of the sewage processor housing 1 from the first water inlet pipe 4 and the second water inlet pipe 5, thereby facilitating the treatment of domestic sewage.

[0027] The sewage treatment unit housing 1 has a first sewage outlet 6 and a second sewage outlet 7 on both sides of its lower end. A sealing sleeve 9 is provided in the middle of the first sewage outlet 6 and the second sewage outlet 7. A servo motor 8 is provided on the outside of the sealing sleeve 9.

[0028] The output shaft of the servo motor 8 passes through the end face of the sealing sleeve 9 and extends into the interior of the sealing sleeve 9. The output shaft of the servo motor 8 is provided with a sealing rotating roller 11 inside the sealing sleeve 9. A square sewage discharge groove 10 is provided in the middle of the sealing rotating roller 11. When cleaning impurities, the servo motor 8 is driven to work by an external control device. The servo motor 8 will drive the sealing rotating roller 11 to work through the output shaft, so that the square sewage discharge groove 10 is in a coplanar state with the first sewage discharge port 6 and the second sewage discharge port 7. The sewage inside the sewage processor shell 1 will be discharged directly from the inside of the first sewage discharge port 6 and the second sewage discharge port 7.

[0029] The sewage processor housing 1 has limiting baffles 13 on both sides near the first inlet pipe 4 and the second inlet pipe 5. The servo motor 8 is electrically connected to the external control device. When sewage enters the sewage processor housing 1 through the first inlet pipe 4, the limiting baffles 13 will block the sewage, and impurity particles will accumulate on both sides of the lower end of the sewage processor housing 1.

[0030] The square sewage trough 10 is set in a coplanar state with the inner end face of the first sewage outlet 6 and the second sewage outlet 7 in the main viewing direction. The lower end of the limiting baffle 13 is reserved with a water guide groove. When sewage enters the sewage processor housing 1, the sewage will seep from the lower end of the limiting baffle 13 to one side of the limiting baffle 13, thereby raising the sewage level on one side of the limiting baffle 13.

[0031] like Figure 4 and 5 As shown, the sewage processor housing 1 has a first limiting plate 16, a second limiting plate 17 and a third limiting plate 22 on both sides of the outlet pipe 14. An MBR membrane plate 20 is provided between the first limiting plate 16 and the second limiting plate 17. When the sewage level on one side of the limiting baffle 13 rises, the sewage will seep into the inside of the MBR membrane plate 20. The MBR membrane plate 20 will block the impurities in the sewage. The filtered sewage will be discharged from the outlet pipe 14.

[0032] The MBR membrane plate 20 has a unidirectional MBR membrane 21 on its end face, a limiting pressure plate 18 is provided on one side of the second limiting plate 17, a supporting slide rod 19 is provided on one side of the outer end face of the limiting pressure plate 18, and a limiting ring 15 is provided on the outer end face of the supporting slide rod 19 between the second limiting plate 17 and the third limiting plate 22.

[0033] The outer end face of the support slide rod 19 is provided with a support spring 12 on one side of the limiting ring 15. One end of the support slide rod 19 is provided with a connecting plate 23. The middle of the outer end of the connecting plate 23 is provided with an adjusting pull plate 24. The support slide rod 19 is sequentially installed through the end faces of the second limiting plate 17 and the third limiting plate 22. When installing the MBR membrane plate 20, the operator can move the adjusting pull plate 24 to one side. The adjusting pull plate 24 will drive the connecting plate 23 and the support slide rod 19 to one side. Then, the operator can insert multiple MBR membrane plates 20 into one side of the first limiting plate 16. Then, the adjusting pull plate 24 can be released. The support spring 12 will press against the limiting ring 15, the support slide rod 19 and the limiting pressure plate 18 to press the MBR membrane plate 20, thereby effectively increasing the convenience and stability of the MBR membrane plate 20 installation. The number of MBR membrane plates 20 can be adjusted according to different types of wastewater.
