[0002] A greywater reuse system is a system that treats wastewater to certain standards through a series of physical, chemical, and biological treatment technologies, enabling it to be reused. Its main purpose is to save water resources, reduce emissions, and reduce the burden on the environment. In a greywater reuse system, sedimentation tanks are usually used in the primary treatment stage, with the main purpose of removing large particulate suspended solids from the water.
[0003] However, most existing methods for reclaimed water reuse involve naturally settling the water inside sedimentation tanks, resulting in slow sedimentation efficiency, which affects wastewater treatment effectiveness and reduces practicality. Therefore, those skilled in the art have provided a sedimentation tank structure for reclaimed water treatment systems to address the problems mentioned in the background section. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a sedimentation tank structure for a greywater reuse treatment system, solving the problems mentioned in the background.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a sedimentation tank structure for a greywater reuse treatment system, comprising a sedimentation tank body, a fixed base installed on the inner side of the sedimentation tank body, a baffle installed above the fixed base inside the sedimentation tank body, and a filter plate arranged on one side of the baffle inside the sedimentation tank body, a connecting plate installed on the upper surface of the filter plate, a positioning plate connected to the upper surface of the connecting plate, a movable plate slidably installed on the upper surface of the sedimentation tank body, a motor installed on the upper surface of the movable plate, a rotating shaft connected to the drive end of the motor, stirring rods symmetrically arranged outside the rotating shaft, a fixed plate installed on one side of the sedimentation tank body, and a cylinder installed on one side of the fixed plate.

[0007] As a further technical solution of this utility model, a water outlet pipe is provided through the upper surface of the sedimentation tank body, and a water pumping pipe is connected to the lower end of the water outlet pipe inside the sedimentation tank body. The water pumping pipe is a telescopic pipe.
[0008] As a further technical solution of this utility model, guide blocks are symmetrically arranged on the lower surface of the moving plate, and guide grooves that slide relative to the guide blocks are opened on the upper surface of the sedimentation tank body.
[0009] As a further technical solution of this utility model, a limiting plate is provided on the inner side of both the baffle and the sedimentation tank body, and the lower surface of the filter plate is in contact with the upper surface of the limiting plate.
[0010] As a further technical solution of this utility model, the connecting plate and the filter plate are arranged in an "L" shape, and the connecting plate and the positioning plate are also arranged in an "L" shape, with the lower surface of the positioning plate in contact with the upper surface of the sedimentation tank body.
[0011] As a further technical solution of this utility model, the upper surface of the fixed seat is inclined, and a discharge port is provided between the baffle and the fixed seat.
[0012] This utility model provides a sedimentation tank structure for a greywater reuse treatment system, which has the following advantages compared with the prior art:
[0013] 1. This design presents a sedimentation tank structure for a greywater reuse treatment system. Through the arrangement of a fixed base, baffle, limiting plate, filter plate, connecting plate, and positioning plate, the filter plate can filter the sewage entering the sedimentation tank body.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1-4 This utility model provides a sedimentation tank structure for a greywater reuse treatment system: It includes a sedimentation tank body 1, a fixed base 2 installed inside the sedimentation tank body 1, a baffle 21 installed above the fixed base 2 inside the sedimentation tank body 1, and a filter plate 3 arranged on one side of the baffle 21 inside the sedimentation tank body 1. A connecting plate 31 is installed on the upper surface of the filter plate 3, and a positioning plate 32 is connected to the upper surface of the connecting plate 31. A movable plate 4 is slidably installed on the upper surface of the sedimentation tank body 1, and a motor 41 is installed on the upper surface of the movable plate 4. The drive end is connected to a rotating shaft 43, and stirring rods 44 are symmetrically arranged on the outside of the rotating shaft 43. A fixing plate 6 is installed on one side of the sedimentation tank body 1, and a cylinder 61 is installed on one side of the fixing plate 6. This arrangement uses the filter plate 3 on one side of the baffle 21 to filter the incoming greywater, thereby preventing pollutants in the greywater from entering the sedimentation tank body 1 and affecting sedimentation. Furthermore, the position of the stirring rods 44 can be adjusted by moving the moving plate 4, so that the greywater and flocculant inside the sedimentation tank body 1 can be stirred and mixed to improve the sedimentation effect.
[0022] like Figure 1 As shown, the fixed end of the cylinder 61 is installed on one side of the fixed plate 6, and the telescopic end of the cylinder 61 is connected to the middle position of one side of the movable plate 4. This arrangement allows the movable plate 4 to slide on the upper surface of the sedimentation tank body 1 when the cylinder 61 is working, so that the position of the stirring rod 44 can be adjusted to flocculate, stir and settle the water inside the sedimentation tank body 1.
[0023] like Figure 4As shown, a water outlet pipe 5 is installed through the upper surface of the sedimentation tank body 1. The lower end of the water outlet pipe 5 is connected to a water pumping pipe 51 inside the sedimentation tank body 1. The water pumping pipe 51 is a telescopic pipe. This arrangement allows the length of the water pumping pipe 51 to be adjusted, so that water inside the sedimentation tank body 1 can be extracted and discharged outward through the water outlet pipe 5.
[0024] like Figure 2 and Figure 3 As shown, guide blocks 42 are symmetrically arranged on the lower surface of the movable plate 4, and guide grooves 11 that slide relative to the guide blocks 42 are opened on the upper surface of the sedimentation tank body 1. This arrangement allows the guide blocks 42 to move within the guide grooves 11, thereby enabling the movable plate 4 to move on the sedimentation tank body 1.
[0025] like Figure 3 As shown, both the baffle 21 and the inner side of the sedimentation tank body 1 are provided with limiting plates 22. The lower surface of the filter plate 3 is in contact with the upper surface of the limiting plate 22. The connecting plate 31 and the filter plate 3 are arranged in an "L" shape. The connecting plate 31 and the positioning plate 32 are also arranged in an "L" shape. The lower surface of the positioning plate 32 is in contact with the upper surface of the sedimentation tank body 1. The upper surface of the fixing seat 2 is inclined. A discharge port is provided between the baffle 21 and the fixing seat 2. This arrangement allows the filter plate 3 to filter the incoming water. The limiting plate 22 can limit the position of the filter plate 3. At the same time, the positioning plate 32 can facilitate the removal and cleaning of the filter plate 3 from the inside of the sedimentation tank body 1.
[0026] The working principle of this utility model is as follows: When the sedimentation tank structure of this utility model for the greywater reuse treatment system is in use, the sewage that needs to be treated for greywater reuse is first fed into the sedimentation tank body 1 through the filter plate 3. Upon entering, the sewage is filtered by the filter plate 3 to remove pollutants. After filtration, the sewage enters the sedimentation tank body 1 through the discharge port between the baffle 21 and the fixed seat 2. After entering, flocculant is added into the sedimentation tank body 1, and the motor 41 on the moving plate 4 is started. This causes the stirring rod 44 outside the rotating shaft 43 to rotate and stir the sewage inside the sedimentation tank body 1, so that the sewage and flocculant inside the sedimentation tank body 1 are mixed to achieve efficient sedimentation. At the same time, the operation of the cylinder 61 causes the moving plate 4 to move, thereby improving the stirring and mixing effect and allowing the sewage to settle quickly. By connecting to the external equipment and the water pumping pipe 51, the sewage inside can be discharged out through the water pumping pipe 51 and the water outlet pipe 5 when the system is turned on.
[0027] All electrical components used in this invention are existing known electrical devices, all of which are connected to an external main controller and external power supply, and all of which can be purchased and used directly on the market. Their structure, circuit, and control principle are all existing known technologies. The appropriate model is selected according to actual use. Therefore, the structure, circuit, and control principle of the device are not described in detail here.
[0028] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
