Technical Field

[0001] This utility model relates to the technical field of multi-stage sewage treatment devices, and in particular to a multi-stage sewage treatment device. Background Technology

[0002] Wastewater refers to water discharged from domestic and industrial processes that has been polluted to some extent. Water that has lost its original function is simply called wastewater. It mainly consists of water used for domestic purposes, which contains a relatively high amount of organic matter and is relatively easy to treat.

[0003] Wastewater treatment equipment is an industrial device that can effectively treat domestic sewage and industrial wastewater in urban areas, preventing sewage and pollutants from flowing directly into water bodies. It is of great significance for improving the ecological environment and enhancing the quality of the city.

[0004] While the above technologies achieve wastewater treatment, the filtration effect of the filter media used to filter wastewater decreases after prolonged use, requiring replacement. Therefore, a multi-stage wastewater treatment device is proposed to solve this problem. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-3 The present invention provides an embodiment of a multi-stage sewage treatment device, comprising a housing 1, a bracket 2 fixedly connected to the outer wall of the housing 1 to support and fix the housing 1, a filter screen 5 detachably connected inside the housing 1, a locking block 6 fixedly connected to the bottom of the filter screen 5, and a locking groove 8 fixedly connected inside the housing 1. The locking block 6 and the locking groove 8 cooperate to achieve the detachable connection of the filter screen 5, facilitating the installation and removal of the filter screen 5. A support plate 7 fixedly connected to the outer wall of the housing 1 provides an installation support platform for the second motor 31 in the adjustment assembly 3. A rotating assembly 4 is provided on the top of the housing 1, and an adjustment assembly 3 is provided on the outer wall of the housing 1.

[0033] Adjustment component 3 includes a second motor 31. The output shaft of the second motor 31 is fixedly connected to a threaded rod 32. A first sliding block 33 is fixedly connected to the outer wall of the threaded rod 32 via a threaded sleeve. The first sliding block 33 is connected to the threaded rod 32 via the threaded sleeve. When the threaded rod 32 rotates, the first sliding block 33 can slide linearly along the axial direction of the threaded rod 32, driving the venting box 34 to move. A venting box 34 for placing filter media and further treating wastewater is fixedly connected to the outer wall of the first sliding block 33. The outer wall of the venting box 34 is fixed... A second sliding block 36 is fixedly connected, and a crossbar 35 is slidably connected inside the second sliding block 36. A fixing block 38 is snapped onto the top of the vent box 34, and a vent box cover 37 is fixedly connected to the top of the fixing block 38. When the filter medium inside the vent box 34 needs to be replaced, the second motor 31 is turned on, causing the first sliding block 33 to rotate on the outer wall of the threaded rod 32, and the second sliding block 36 to slide on the outer wall of the crossbar 35, moving the vent box 34 out of the box body 1. Then, the vent box cover 37 snapped onto the top of the vent box 34 is opened to replace the internal filter medium.

[0034] Reference Figures 2-4 The outer wall of the threaded rod 32 is rotatably connected to the inside of the housing 1, and the outer wall of the crossbar 35 is fixedly connected to the inside of the housing 1, forming a stable support structure and providing a sliding track for the second sliding block 36. The outer wall of the vent box 34 is slidably connected to the inside of the housing 1. The bottom of the second motor 31 is fixedly connected to the top of the support plate 7. The outer wall of the first sliding block 33 is slidably connected to the inside of the housing 1. The inside of the housing 1 is provided with a sliding space and guide structure that are adapted to the outer wall of the vent box 34, so that the vent box 34 can slide smoothly inside the housing 1. The outer wall of the second sliding block 36 is slidably connected to the inside of the housing 1. There are two sets of vent boxes 34, and the two sets of vent boxes 34 slide along a... The sliding blocks 33 are mirror-distributed along their central axis. The outer wall of the locking block 6 is engaged with the inside of the locking groove 8. The rotating assembly 4 includes a first motor 41. The output shaft of the first motor 41 is fixedly connected to a rotating shaft 42. The rotating shaft 42 transmits the power of the first motor 41 to the nanomembrane assembly 43, causing the nanomembrane assembly 43 to rotate. The outer wall of the rotating shaft 42 is fixedly connected to the nanomembrane assembly 43. The outer wall of the nanomembrane assembly 43 is fixedly connected to a retaining ring 44. The outer wall of the retaining ring 44 is rotatably connected to the inside of the housing 1. The inside of the housing 1 is provided with a rotating connection structure adapted to the retaining ring 44. The bottom of the first motor 41 is fixedly connected to the top of the housing 1. After the sewage enters from the top of the housing 1, it is first filtered by the filter screen 5. The filter screen 5 is engaged with the locking block 6 at the bottom in the locking groove 8 inside the housing 1, which can intercept large particulate impurities in the sewage. When filter screen 5 needs cleaning, it can be directly disassembled and removed for easy maintenance. Then, motor 41 is turned on to make the nanomembrane module 43 rotate, which improves the filtration effect of the wastewater entering the nanomembrane module 43 for filtration.

[0035] Working principle: During use, wastewater enters from the top of the tank 1 and is first initially filtered by the filter screen 5. The filter screen 5 is engaged in the slot 8 inside the tank 1 by the bottom locking block 6, which can intercept large particles of impurities in the wastewater. When the filter screen 5 needs to be cleaned, it can be directly disassembled and removed for easy maintenance. Then, the first motor 41 is turned on, causing the nano-membrane module 43 to rotate, which improves the filtration effect of the wastewater entering the nano-membrane module 43 for filtration. When it is necessary to replace the filter medium inside the venting box 34, the second motor 31 is turned on, causing the first sliding block 33 to rotate on the outer wall of the threaded rod 32 and the second sliding block 36 to slide on the outer wall of the crossbar 35, moving the venting box 34 out of the tank 1. Then, the venting box cover 37, which is locked on the top of the venting box 34, is opened to replace the internal filter medium.
