Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, and in particular to a rural domestic sewage treatment device. Background Art

[0002] With the development of rural economy and the improvement of residents' living standards, the problem of rural domestic sewage treatment has become increasingly prominent. Due to the imperfect infrastructure in rural areas, especially in the drainage system, the rainwater and sewage separation treatment method is basically impossible to achieve. Therefore, rural domestic sewage often contains a large amount of impurities, including but not limited to leaves, small branches, mud and other organic matter. These impurities not only increase the difficulty of sewage treatment, but also put higher requirements on treatment equipment.

[0003] In the traditional sewage filtration process, impurities such as leaves and branches are difficult to be effectively filtered and cleaned due to their shape and material characteristics. After entering the treatment system, these impurities often clog the pipes, reduce treatment efficiency, and even damage the treatment equipment, thereby increasing maintenance and repair costs.

[0004] In response to this problem, Chinese patent CN116351127A discloses a rural domestic sewage treatment device, which is designed with a hook structure, which is intended to pierce and hook impurities such as leaves and plastic bags in the sewage to achieve the purpose of cleaning. However, this design has certain defects in practical applications. Specifically, when the hook structure hooks impurities such as leaves, silt and other debris may also enter the storage chamber. These silt and debris will affect the activity of the first filter and may even cause the filter to be blocked. Once the filter is blocked, the operation of the entire mechanical structure will be affected, and may even cause the equipment to fail, thereby affecting the continuity and efficiency of sewage treatment.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. The utility model is further described in combination with the drawings and embodiments:

[0021] like Figure 1-Figure 6 As shown, a rural domestic sewage treatment device includes a box body 1, a rotating shaft 2 is installed on the left side of the top of the box body, an upper filter frame 3 is rotatably connected to the rotating shaft, a lower filter frame 4 is fixedly connected to the bottom of the upper filter frame, a plurality of cross grids 31 are formed in the upper filter frame, a plurality of hooks 32 are provided on the cross grids, and a lifting plate 33 is installed at one end of the upper filter frame away from the rotating shaft. Through the design of the upper filter frame and the cross grid, large particles of impurities in the sewage, such as leaves, branches, etc., can be preliminarily filtered out. The setting of the hooks further enhances the filtering effect, and can effectively hook and remove fibrous impurities in the sewage. The lifting plate is convenient for users to operate, and the upper filter frame can be easily lifted for cleaning.

[0022] Furthermore, the lower filter frame includes a left end plate 44 and a side connecting plate 41. The bottom of the upper filter frame is fixedly connected with a left end plate and two side connecting plates. The left end plate is connected with side connecting plates on both sides. The side connecting plates are connected with an upper guide plate 42 and a lower guide plate 43. The two groups of side connecting plates, the upper guide plate and the lower guide plate form a plug-in chute. A bent filter plate 48 is slidably fitted in the plug-in chute. The bent filter plate is provided with a plurality of water filter holes. A connecting plate 47 is rotatably connected to the end of the bent filter plate. A blocking plate 45 is fixedly connected to the connecting plate. The blocking plate is fixedly connected to the two side connecting plates by bolts 46. The design of the lower filter frame further finely filters the sewage through the bent filter plate, and the water filter holes can remove finer impurities. The plug-in chute structure allows the bent filter plate to be easily disassembled and installed, and is easy to clean and replace. The fixing method of the blocking plate and the bolts ensures the sealing and stability of the device.

[0023] In at least one embodiment, the box body includes a left plate 11, a right plate 12, a side plate 14 and a bottom plate 13, the left plate and the right plate are connected together by two side plates, the bottom of the left plate, the right plate and the side plate are installed with a bottom plate 13 inclined downward, the right plate is installed with a water outlet 16, and the bottom of the bottom plate is provided with a plurality of legs 15. The structural design of the box body is reasonable, which is convenient for the flow and treatment of sewage. The bottom plate inclined downward helps the sewage to flow naturally to the water outlet, thereby improving the sewage discharge efficiency. The setting of the legs allows the device to be stably placed on the ground, ensuring the smooth progress of sewage treatment.

[0024] Furthermore, an elastic plate 51 is installed on the left plate, and a vibration motor 52 is fixedly connected to the bottom of the elastic plate. The combination design of the elastic plate and the vibration motor can help the impurities on the filter frame fall off through vibration, reduce blockage, and improve the filtering efficiency. At the same time, it also helps to prevent excessive accumulation of impurities on the filter frame, thereby extending the service life of the filter frame.

[0025] Furthermore, the two side plates and the right plate form a slot, in which the right end of the upper filter frame is snapped. The slot design enables the upper filter frame to be stably fixed on the box body, ensuring the stability and reliability of the filtering process. At the same time, the snap-in method also makes it easy for users to disassemble and install the upper filter frame, simplifying the operation process of cleaning and maintenance.

[0026] Working method: Install the sewage treatment device in a place suitable for sewage treatment, ensure that the device is placed stably and the legs stably support the ground. Check whether all parts are intact, ensure that the upper filter frame, lower filter frame, elastic plate, vibration motor and other parts are not damaged, and confirm that the blocking plate is fixed to the side connecting plate with bolts. Ensure that the water outlet is unobstructed so that the treated water can be discharged smoothly.

[0027] When in use, rural domestic sewage is introduced into the box. The sewage will first flow through the upper filter frame, where impurities such as leaves and branches will be hooked by the barbs to achieve preliminary filtration. The water filtered by the upper filter frame will flow into the lower filter frame, and the bent filter plate will further filter out the fine impurities in the water. As the sewage continues to flow in, the impurities on the upper filter frame will gradually increase. At this time, people can turn the upper filter frame so that the upper filter frame is against the surface of the elastic plate, start the vibration motor under the elastic plate, and use vibration to help the impurities on the barbs fall off to the ground. At this time, silt and other impurities on the lower filter frame will also fall. Regularly check the bent filter plate in the lower filter frame. If it is seriously blocked, remove the bolts, turn the connecting plate, and slide the bent filter plate out of the plug-in slide for cleaning or replacement. After cleaning, reinstall the bent filter plate and fix the sealing plate to the side connecting plate with bolts to ensure the sealing of the device.

[0028] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions in the specification are only to illustrate the principles of the utility model.
