[0002] Sewage treatment refers to the process of purifying sewage so that it meets the water quality requirements for discharge into a certain water body or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care and catering. The treatment of sewage requires the use of special equipment to mix it with flocculants to achieve the purpose of purification. However, while the existing sewage treatment devices are mixing the sewage and flocculants, it is difficult to use cleaning scrapers to clean and impact the sewage and flocculants adhered to the inner wall of the device, resulting in the sewage and flocculants adhered to the inner wall of the device being difficult to fall to the bottom of the device for discharge. As a result, the sewage and flocculants adhered to the inner wall need to be cleaned manually, which consumes labor and makes the overall maintenance of the device inconvenient. At the same time, the cleaning scraper will be deformed after long-term use, which will cause wear on the inner wall of the device. Utility Model Content

[0003] In order to overcome the above-mentioned defects, the utility model provides a sewage treatment device which is easy to maintain, and solves the problem that the existing sewage treatment device is difficult to use a cleaning scraper to clean and impact the sewage and flocculant adhered to the inner wall while mixing the sewage and flocculant, resulting in the sewage and flocculant adhered to the inner wall of the device being difficult to fall to the bottom of the device for discharge, resulting in the sewage and flocculant adhered to the inner wall needing to be cleaned manually, which not only consumes labor, but also makes the maintenance of the entire device inconvenient. At the same time, the cleaning scraper will be deformed after long-term use, thereby causing wear to the inner wall of the device.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sewage treatment device that is easy to maintain, comprising a treatment box, a bearing is clamped at the bottom of the treatment box, a roller is rotatably connected in the bearing, one end of the roller is fixedly connected to a motor, the output shaft of the motor is fixedly connected to one end of the roller, a plurality of mixing blades are fixedly connected to the outside of the roller, a telescopic rod is fixedly connected to the outside of the roller, the other end of the telescopic rod is fixedly connected to a cleaning shovel edge, a spring is connected to the outside of the telescopic rod, one end of the spring is fixedly connected to the outside of the roller, and the other end of the spring is fixedly connected to the inner side of the cleaning shovel edge, and a plurality of protrusions are fixedly connected to the inner wall of the treatment box.

DETAILED DESCRIPTION

[0018] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0019] like Figure 1-3 As shown, the utility model provides a technical solution: a sewage treatment device that is easy to maintain, comprising a treatment box 1, a hinge block 10 is movably connected to the top of the treatment box 1, and a box cover 11 is fixedly connected to the outside of the hinge block 10. The movable connection between the hinge block 10 and the treatment box 1 enables the box cover 11 to have a position rotation condition, so that when the inside of the treatment box 1 needs to be maintained, the box cover 11 can be opened, so that the staff can easily maintain the inside of the treatment box 1;

[0020] The treatment box 1 is fixedly connected to a discharge port 12, and a valve 13 is arranged inside the discharge port 12. The discharge port 12 allows the sewage in the treatment box 1 to be discharged smoothly to the outside, which is convenient for the next purification process of the sewage. The valve 13 allows the discharge port 12 to be opened or closed to prevent the sewage in the treatment box 1 from leaking through the discharge port 12 and causing pollution to the surrounding environment.

[0021] A filter screen 14 is fixedly connected inside the discharge port 12, and a feed port 15 is fixedly connected outside the treatment box 1. The filter screen 14 enables the sewage to have a certain filtering function when it is discharged through the discharge port 12, thereby effectively blocking the residue in the sewage to improve the sewage purification effect, and the feed port 15 allows the sewage and the flocculant to have space to be injected into the treatment box 1, which is convenient for injecting the sewage and the flocculant into the treatment box 1 for mixed purification;

[0022] Three support legs 17 are fixedly connected to the bottom of the treatment box 1. A buffer layer is provided at the bottom of the support legs 17. The support legs 17 use the buffer layer to ensure that the treatment box 1 has good stability and buffering when it is placed on the ground, thereby reducing the shaking of the treatment box 1 when the mixing blades 5 mix the sewage and the flocculant.

[0023] A bearing 2 is clamped at the bottom of the treatment box 1, a roller 3 is rotatably connected inside the bearing 2, one end of the roller 3 is fixedly connected to a motor 4, the output shaft of the motor 4 is fixedly connected to one end of the roller 3, and a plurality of mixing blades 5 are fixedly connected outside the roller 3, so that when the motor 4 is running, the output shaft can be used to drive the roller 3 to rotate, so that the roller 3 can drive the plurality of mixing blades 5 and the telescopic rod 6 to rotate smoothly, so that the sewage and flocculant in the treatment box 1 can be mixed and purified when the plurality of mixing blades 5 are in a rotating state;

[0024] The motor 4 is fixedly connected to two motor fixing blocks 16, and the upper parts of the two motor fixing blocks 16 are fixedly connected to the bottom of the processing box 1. The motor fixing blocks 16 provide the motor 4 with a fixing point, thereby reducing the adverse effects caused by shaking and displacement during the operation of the motor 4, so as to ensure the stability of the motor 4 during operation;

[0025] A telescopic rod 6 is fixedly connected to the outside of the roller 3, and the other end of the telescopic rod 6 is fixedly connected to a cleaning shovel edge 7. A spring 8 is connected to the outside of the telescopic rod 6, one end of the spring 8 is fixedly connected to the outside of the roller 3, and the other end of the spring 8 is fixedly connected to the inner side of the cleaning shovel edge 7. A plurality of protrusions 9 are fixedly connected to the inner wall of the treatment box 1, so that the cleaning shovel edge 7 is driven by the telescopic rod 6 and the spring 8 to perform a circular motion. When it contacts with a plurality of protrusions 9 and is convexly squeezed, the elastic force of the telescopic rod 6 and the spring 8 can be used to clean and impact the sewage and flocculant adhered to the inner wall of the treatment box 1, so that the sewage and flocculant adhered to the inner wall of the treatment box 1 fall off, thereby eliminating the need for staff to clean and maintain the interior of the treatment box 1 all the time, so as to improve the ease of maintenance of the treatment box 1, and the telescopic rod 6 cooperates with the elastic force of the spring 8 to enable the cleaning shovel edge 7 to have deformation adjustment force.

[0026] The working principle of the utility model is:

[0027] When it is necessary to mix the sewage and the flocculant, first inject the sewage and the flocculant into the treatment box 1 through the feed port 15, and then start the motor 4, so that the output shaft of the motor 4 drives the roller 3 to rotate, and the roller 3 drives the plurality of mixing blades 5 to rotate, so that the sewage and flocculant in the treatment box 1 can be mixed when the plurality of mixing blades 5 rotate, and at the same time, the roller 3 can drive the telescopic rod 6 to rotate synchronously, so that the telescopic rod 6 drives the cleaning shovel edge 7 to use the elastic force provided by the spring 8 so that the cleaning shovel edge 7 can clean and impact the sewage and flocculant adhered to the inner wall of the treatment box 1 to perform maintenance work.

[0028] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.
