Technical Field
[0001] The utility model relates to the technical field of sewage treatment, and particularly relates to an integrated domestic sewage treatment and recycling device. Background Technique
[0002] Domestic sewage refers to the wastewater generated by residents in their daily lives, mainly from residential buildings and public buildings, such as residences, institutions, schools, hospitals, stores, public places, and the toilets of industrial enterprises. This wastewater includes washing water, toilet excrement, kitchen sewage, etc., which contains a large amount of organic matter (such as proteins, carbohydrates, fats, urea, ammonia nitrogen, etc.), bacteria, viruses, as well as suspended solids and impurities. If these substances are directly discharged into the environment without treatment, they will cause serious pollution to the environment. Treating domestic sewage is an inevitable requirement for protecting the ecological environment, ensuring human health, promoting sustainable development, and complying with laws and regulations. By using various methods such as physical, chemical, and biological methods to treat domestic sewage, the pollutants in the sewage can be effectively removed, making it meet the discharge standard or the reclaimed water standard, and realizing the recycling and sustainable development of water resources.
[0003] When some existing domestic sewage treatment devices are in use, the deposits on their filter plates cannot be directly discharged, it is not convenient to quickly remove the filter plates, and it is time-consuming and laborious to clean them.
[0004] For example, a domestic sewage treatment device disclosed in the patent with the publication number CN218357679U. The domestic sewage treatment device of this patent achieves the effect of crushing large particulate matter in the water flow by setting a vibration mechanism, and knocks on the filter plate to prevent the filter plate from being blocked. By setting a filtering mechanism, it achieves the effect of filtering the water flow and enables the filter plate to quickly reset without affecting subsequent filtering. By setting a deflector plate, it achieves the effect of diverting the water flow, solving the problems that in the use of existing sewage treatment devices, due to the fact that domestic sewage contains things such as hair, animal hair, various fibers, etc. that are not easily decomposed, it will cause the filter plate to be blocked, affecting the sewage treatment efficiency, and it is not convenient to clean and replace the filter plate, affecting the use.
[0005] Although the design of the above domestic sewage treatment device improves the sewage treatment efficiency and the ability to prevent the filter plate from being blocked through the vibration mechanism and the filtering mechanism, there are still inconveniences in cleaning the foreign matters (such as hair, animal hair, fibers, etc.) accumulated on the filter plate. Although a detachable filter plate is designed for cleaning, in actual operation, users need to manually rotate the limit bolts to release the fixation and then remove the filter plate from the fixing rod. This process is relatively cumbersome, especially in scenarios where the filter plate needs to be frequently cleaned, increasing the operation difficulty and time cost.

A first operation door 7 is installed inside the first slag discharge port, and a second operation door 8 is installed inside the second slag discharge port.
[0035] In one aspect of this embodiment, both the first filter screen plate 5 and the second filter screen plate 6 are inclined. The surface pore diameter of the first filter screen plate 5 is larger than that of the second filter screen plate 6. Handles are installed at one ends of the first filter screen plate 5 and the second filter screen plate 6 close to the outside of the water injection pipeline 2. Transparent observation windows are installed in the middle of the first operation door 7 and the second operation door 8. Guide chute 9 is installed at the position below the first slag discharge port and the second slag discharge port on the front of the water injection pipeline 2. A transfer vehicle 10 is arranged on one side of the treatment tank 1 close to the water injection pipeline 2. A medicine feeding pipeline 11 is installed on the other side of the top of the treatment tank 1. The bottom of the medicine feeding pipeline 11 is communicated with the inside of the treatment tank 1. A driving motor 12 is installed in the middle of the top of the treatment tank 1. A stirring shaft 13 is rotatably connected inside the treatment tank 1. The top end of the stirring shaft 13 extends to the outside of the treatment tank 1 and is in transmission connection with the driving motor 12. Stirring blades 14 are installed on the surface of the stirring shaft 13. The number of the stirring blades 14 is set to be multiple, and the multiple stirring blades 14 are evenly distributed on the surface of the stirring shaft 13. A control console 15 is installed on the top of the treatment tank 1. A drain pipe 16 is installed on one side of the surface of the treatment tank 1 close to its bottom. An electromagnetic valve is installed in the middle of the drain pipe 16. The driving motor 12 and the electromagnetic valve are both electrically connected to the control console 15.
[0036] The working principle of the present utility model:
[0037] Referring to the attached Figures 1-5 specification, when using the present utility model, first, domestic sewage to be treated is injected into the treatment tank 1 through the water injection pipeline 2. Before the sewage flows into the treatment tank 1, it will first pass through two filtering devices inside the water injection pipeline 2. The sewage first encounters the first filter screen plate 5. The surface pore diameter of this screen plate is relatively large, which can initially intercept larger impurities such as plastic bags and leaves. Subsequently, the sewage continues to flow downward and passes through the second filter screen plate 6. Its surface pore diameter is smaller, which can further remove smaller suspended substances and particulate matters.
[0038] During the water injection process, the clogging conditions on the first filter screen plate 5 and the second filter screen plate 6 can be checked through the transparent observation window. Regularly open the first operation door 7 and the second operation door 8 to discharge the deposits on the first filter screen plate 5 and the second filter screen plate 6. After the deposits are discharged from the slag discharge port, they are finally guided by the material guiding chute 9 and fall into the transfer vehicle 10, which is convenient for subsequent centralized treatment. When necessary, the filter screen plate can be pulled out of the inclined chute by holding the handle for cleaning. After the filter screen plate is cleaned, it only needs to be inserted back into the inclined chute;
[0039] The water injection process completes the preliminary filtration. Through the design of the two-stage filter screen plate, most of the suspended solids and particulate matters in the sewage are effectively removed. The preliminarily treated sewage flows into the treatment tank 1. After the sewage in the treatment tank 1 reaches the preset water level, an appropriate amount of treatment agents, such as flocculants, disinfectants, etc., are added to the sewage through the dosing pipeline 11 to further purify the water quality;
[0040] After the agent is added, start the drive motor 12 through the control console 15, and drive the stirring blade 14 to rotate through the stirring shaft 13 to make the agent fully mixed with the sewage evenly. The stirring process helps the agent to dissolve quickly and be evenly distributed in the sewage, improving the treatment efficiency. After the stirring is completed, turn off the drive motor 12 and let the sewage stand in the treatment tank 1 for a period of time to form flocs of suspended solids under the action of the agent and precipitate to the bottom of the tank. Static precipitation is a key link to remove pollutants such as suspended solids and colloids in the sewage, which helps to improve the effluent water quality. After the suspended solids in the sewage are fully precipitated, open the solenoid valve on the drain pipe 16 to discharge the treated clear water for recycling use. The discharged clear water can be used for various purposes such as agricultural irrigation, urban greening, and industrial cooling, realizing the recycling of water resources.
