Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically a mixing reaction device for wastewater treatment in urban construction. Background Technology

[0002] With the acceleration of urbanization, sewage treatment has become a key link in protecting the ecological environment and public health. Sewage treatment is a process of purifying sewage to meet the water quality requirements for discharge into a water body or reuse. It is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, and catering. Sewage treatment equipment is required in urban construction.

[0003] Traditional wastewater treatment devices typically have a filter screen installed inside. Under the influence of gravity, impurities inside the wastewater are filtered out through the filter screen before reacting with chemicals. However, the filter screen is prone to clogging after prolonged use, which affects the filtration effect.

[0004] For example, a mixed reaction device for urban wastewater treatment based on environmental protection construction (Announcement No.: CN212655583U) includes components such as a first filter screen, a second filter screen, a fixed base, a rotating plate, and springs. Impurities are filtered through the first and second filter screens, and under the action of gravity, the impurities are pushed downwards by the rotating plate 7, causing them to fall into the collection box through the outlet. However, in actual use, after the impurities clog the first and second filter screens, gravity alone cannot make the impurities fall onto the rotating plate, and the interior of the first and second filter screens will still be full of impurities. That is, the problem mentioned above exists that the filter screens are prone to clogging after long-term use, affecting the filtration effect. Therefore, we need to propose a mixed reaction device for urban wastewater treatment. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0018] Please see Figure 1-4 This utility model provides a technical solution: A mixing reaction device for urban construction wastewater treatment includes: a filter box 1, a mixing box 2, two sets of filter screens 3, a cleaning mechanism 5, a water conveying mechanism 6, and a stirring mechanism 7, etc. The mixing tank 2 is fixedly connected to the filter tank 1 on one side. A connecting groove 4 is provided at the connection between the filter tank 1 and the mixing tank 2. The filter tank 1 and the mixing tank 2 are connected through two sets of connecting grooves 4. Two sets of filter screens 3 are installed inside the filter tank 1. A sewage inlet 10 is fixedly connected to the top of the filter tank 1. A cleaning mechanism 5 is installed on the filter tank 1 to clean the two sets of filter screens 3. A water conveying mechanism 6 is installed on the filter tank 1 below the two sets of filter screens 3. A stirring mechanism 7 is installed on the mixing tank 2 to improve the mixing efficiency of sewage and chemicals. In this embodiment, wastewater enters the interior of the filter box 1 through the wastewater inlet 10. Under the action of gravity, the wastewater passes through two sets of filter screens 3. The two sets of filter screens 3 filter impurities in the wastewater, and the filtered wastewater enters the interior of the mixing box 2 through two sets of connecting channels 4. Specifically, the mesh count of the two sets of filter screens 3 is not the same. The upper set of filter screens 3 should be smaller than the lower set of filter screens 3. The upper set of filter screens 3 is used to filter large particulate impurities, while the lower set of filter screens 3 is used to filter small particulate impurities. It is worth noting that the mesh count of the two sets of filter screens 3 is not limited here and should be determined according to the specific usage. The cleaning mechanism 5 includes two sets of threaded rods 51, two sets of cleaning brushes 56, two sets of limiting rods 52, two sets of driven gears 53, a first drive motor 54, and a drive gear 55. The two sets of threaded rods 51 are rotatably mounted on one side of the inner wall of the filter box 1. One end of each of the two sets of cleaning brushes 56 is threaded to the outer wall of the two sets of threaded rods 51. One end of each of the two sets of threaded rods 51 passes through the filter box 1 and is fixedly connected to the two sets of driven gears 53. The first drive motor 54 is fixedly mounted on one side of the filter box 1. The drive gear 55 is fixedly sleeved on the outer wall of the output shaft of the first drive motor 54, and the drive gear 55 meshes with the two sets of driven gears 53. In this embodiment, the output shaft of the first drive motor 54 drives the drive gear 55 to rotate, which in turn drives the two sets of driven gears 53 meshing with it to rotate, which in turn drives the two sets of threaded rods 51 to rotate, causing the two sets of cleaning brushes 56 to move and clean the two sets of filter screens 3, preventing impurities from clogging the filter screens 3 and ensuring the filtration effect of the filter screens. It is worth noting that when the sewage is stopped, no sewage enters the interior of the filter box 1, and the sewage in the device is located inside the mixing box 2 and reacts with the reagent, it is more appropriate to clean the filter screens 3 at this time, and no extra time is wasted. Both sets of limiting rods 52 are fixedly installed on the other side of the inner wall of the filter box 1, and the other ends of the two sets of cleaning brushes 56 are slidably installed on the outer wall of the two sets of limiting rods 52 respectively, and the bottom of the two sets of cleaning brushes 56 are respectively attached to the surface of the two sets of filter screens 3. In this embodiment, two sets of limiting rods 52 limit the two sets of cleaning brushes 56, so that the two sets of cleaning brushes 56 can move when the two sets of threaded rods 51 rotate. Two sets of water guide plates 11 are fixedly connected to both sides of the inner wall of the filter box 1. All four sets of water guide plates 11 are inclined and are located above the two sets of cleaning brushes 56 respectively. In this embodiment, the four sets of water guide plates 11 can protect the two sets of threaded rods 51 and the two sets of limiting rods 52. Specifically, after the sewage enters the filter box 1, it will flow to the bottom of the filter box 1 under the action of gravity. Sewage will not accumulate on the two sets of filter screens 3. The four sets of water guide plates 11 can prevent the sewage from contacting the two sets of threaded rods 51 and the two sets of limiting rods 52, and prevent impurities in the sewage from adhering to the threads of the threaded rods 51 and the outer wall of the limiting rods 52, thus ensuring the stability of the cleaning mechanism 5. A partition 8 is fixedly installed at the bottom of the filter box 1. The partition 8 is located below the filter screen 3. A drain door 9 is provided on one side of the partition 8 in the filter box 1. In this embodiment, the partition 8 can separate impurities and sewage. Impurities are located on one side of the partition 8, while sewage is located on the other side of the partition 8 and enters the interior of the mixing tank 2. Impurities can be discharged by opening the drain door 9. The water conveying mechanism 6 includes a crossbar 61, a second drive motor 62, and several sets of water conveying blades 63. The crossbar 61 is rotatably installed on the other side of the filter box 1 located on the partition 8. One end of the crossbar 61 passes through the filter box 1 and is fixedly connected to the second drive motor 62. Several sets of water conveying blades 63 are all fixedly connected to the outer wall of the crossbar 61. In this embodiment, the output end of the second drive motor 62 drives the crossbar 61 connected to it to rotate, so that several sets of water conveying blades 63 rotate, which facilitates the sewage to enter the interior of the mixing tank 2 and enables the sewage in the filter box 1 and the mixing tank 2 to flow, thereby improving the mixing efficiency. It is worth noting that the height of the sewage should not be higher than the height of the lower set of filter screens 3 to prevent the sewage from entering the impurity storage area. Specifically, in optional embodiments, a water level sensor can be installed inside the filter box 1 or the mixing box 2, or an observation window can be installed on the filter box 1 to facilitate understanding the height of the wastewater; The stirring mechanism 7 includes a vertical rod 71, a third drive motor 72, and several sets of stirring blades 73. The vertical rod 71 is rotatably installed inside the mixing box 2. The top of the vertical rod 71 passes through the mixing box 2 and is fixedly connected to the third drive motor 72. Several sets of stirring blades 73 are all fixedly connected to the outer wall of the vertical rod 71. In this embodiment, the output end of the third drive motor 72 drives the vertical rod 71 connected to it to rotate, which in turn drives several sets of stirring blades 73 to rotate, thereby improving the reaction efficiency of wastewater and reagents. The top of the mixing tank 2 is fixedly connected to a chemical inlet pipe 12, and the bottom side of the mixing tank 2 is fixedly connected to a drain pipe 13. A valve 14 is installed on the drain pipe 13. The chemical enters the interior of the mixing tank 2 through the chemical inlet pipe 12 and reacts with the sewage. After the sewage treatment is completed, the valve 14 is opened and the treated sewage can be discharged through the drain pipe 13.

[0019] Working principle: When this utility model is in use, sewage enters the interior of the filter box 1 through the sewage inlet 10. Impurities in the sewage are filtered through two sets of filter screens 3. A cleaning mechanism 5 is provided to clean the impurities on the two sets of filter screens 3, so as to avoid impurities clogging the filter screens 3 and ensure the filtration effect of the filter screens. The filtered sewage enters the interior of the mixing box 2 through two sets of connecting channels 4. The reaction efficiency between sewage and reagent is improved by the cooperation of the water conveying mechanism 6 and the stirring mechanism 7.
