Description

Technical Field

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

[0002] Decentralized sewage treatment is a system that treats sewage by dispersing sewage treatment equipment at the place where sewage is generated. Compared with traditional centralized sewage treatment, this system has many advantages, including saving space and equipment maintenance costs, avoiding environmental pollution and reducing costs. With the improvement of environmental awareness and the continuous development of sewage treatment technology, decentralized sewage treatment will become an important development direction of sewage treatment in the future. For small towns, rural areas and remote areas with relatively dispersed populations, centralized treatment of domestic sewage is not suitable due to geographical conditions and economic factors. At this time, decentralized domestic sewage treatment should be selected and developed according to local conditions.

[0003] Existing decentralized sewage treatment devices often face a significant problem during the treatment process: filter plates are prone to clogging. Because sewage contains a large amount of suspended solids, particulate matter, and organic matter, these impurities easily deposit and adhere to the filter plate surface when passing through it, causing the filter plate pores to gradually decrease until they are completely clogged. This not only seriously affects sewage treatment efficiency but also increases the difficulty and cost of equipment maintenance. Therefore, this utility model proposes a decentralized sewage treatment device. Utility Model Content

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] The following describes the preferred embodiments of the device of the present invention.

[0027] See also Figure 1-4As shown, the decentralized sewage treatment device includes a treatment box 1, a water inlet pipe 2 is provided on one side of the treatment box 1 and passes through the interior of the treatment box 1, a filter plate 3 with an inclined angle is provided inside the treatment box 1, the water inlet pipe 2 extends to the interior of the treatment box 1 and is close to the upper side of the filter plate 3, and a clearing component 8 is provided on the surface of the filter plate 3 close to the water inlet pipe 2. The bottom side of the filter plate 3 and the inner wall of one side of the treatment box 1 are clamped with a separation plate 5 through a fixed clamping seat 4. The filter plate 3 and the separation plate 5 respectively form a filter chamber 6 and a separation chamber 7 with the inner wall of the treatment box 1. The independent filter chamber 6 and separation chamber 7 realize the separation and filtration of sewage and dirt. The bottom of the filter chamber 6 is connected to the three-way pipe 10 provided at the bottom of the separation chamber 7 through an extended connecting pipe 9. The other pipe end of the three-way pipe 10 is passed through the connecting pipe 9 to the interior of the disinfection box 11 provided next to the treatment box 1. The top side of the interior of the disinfection box 11 is provided with an ultraviolet disinfection lamp 1101 for purifying sewage. The ultraviolet disinfection lamp 1101 irradiates the sewage and uses the bactericidal effect of ultraviolet rays to achieve the purpose of disinfection and purification. The bottom of the treatment box 1 is evenly distributed with supporting legs 12.

[0028] Furthermore, a box cover 101 is installed on the top of the treatment box 1, and a handle 102 is provided on the top of the box cover 101. An inverted trapezoidal plate 103 is provided at the bottom of the treatment box 1. The upper part of the inverted trapezoidal plate 103 is wider and the lower part is narrower, forming a natural diversion slope. When the filtered sewage flows from the filter plate 3 into the bottom of the treatment box 1, the trapezoidal plate 103 can guide the sewage to flow more smoothly to the connecting pipe 9 and the three-way pipe 10, and finally enter the disinfection box 11 for further treatment.

[0029] In another embodiment provided by the present invention, Figure 2 and 4 As shown, the clearing assembly 8 includes a turntable 801 fitted on the surface of the filter plate 3, a clearing rod 802 is provided on the corresponding ring outside the turntable 801, a rotating rod 803 is fixedly connected to the axis of the turntable 801, a rotating wheel 806 is provided above the processing box 1, and the bottom of the rotating wheel 806 is fixedly connected to a connecting rod 805 extending to the inside of the processing box 1, and the bottom end of the connecting rod 805 is movably connected to one end of the rotating rod 803 through a universal box 804.

[0030] Furthermore, one side of the clearing rod 802 is provided with an inclined surface 807 for facilitating cleaning of dirt. The design of the inclined surface 807 enables the clearing rod 802 to more effectively scrape off impurities on the filter plate 3 during rotation, thereby improving the clearing efficiency.

[0031] Specifically, the clearing program is started by rotating the wheel 806 without entering the interior of the processing box 1. The flexible connection between the connecting rod 805 and the rotating rod 803 is achieved through the universal box 804, and the rotation of the connecting rod 805 is transmitted to the rotating rod 803 for rotation. The rotating rod 803 thereby drives the turntable 801 to rotate. When the turntable 801 rotates, the clearing rod 802 rotates accordingly, effectively driving the dirt on the filter plate 3 to the separation plate 5, preventing the filter plate 3 from being blocked by some large-volume dirt stuck in the filter plate 3 due to the impact of the water inlet pipe 2.

[0032] During use, the sewage to be treated enters the treatment box 1 through the water inlet pipe 2, and impurities are separated from the sewage on the filter plate 3. The impurities slide down to the separation plate 5 along the inclined angle of the filter plate 3, and the clean water enters the filter chamber 6, and the impurities entering the separation plate 5 are filtered and separated again by the setting of the separation plate 5. The separated sewage enters the separation chamber 7, and the filtered sewage in the separation chamber 7 and the filter chamber 6 enters the disinfection box 11 through the connecting pipe 9 and the three-way pipe 10. In the disinfection box 11, the ultraviolet disinfection lamp 1101 irradiates the sewage, and the bactericidal effect of ultraviolet rays is used to achieve the purpose of disinfection and purification. When the filter plate 3 tends to be blocked, the wheel 806 above the treatment box 1 is rotated to drive the turntable 801 and the clearing rod 802 in the clearing assembly 8 to rotate, and the mechanical force of the clearing rod 802 is used to remove impurities attached to the surface of the filter plate 3 to keep the filter plate 3 unobstructed.

[0033] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions merely illustrate the principles of the present invention. Various changes and improvements are possible without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed for the present invention is defined by the appended claims and their equivalents.
