Technical Field

[0001] The utility model relates to the technical field of sewage treatment, and more specifically, to a sewage treatment device for water ecological environment governance. Background Art

[0002] With the rapid development of global industrialization and urbanization, the problem of water resource pollution has become increasingly prominent, which has a serious impact on human life, production and ecological environment, resulting in the deterioration of the surrounding ecological environment. In the process of sewage treatment, sewage treatment devices are often used to make the sewage meet the water quality requirements for discharging into a certain water body or reusing, so as to reduce the negative impact on the water ecosystem.

[0003] The utility model patent with the application number 202222667057.X discloses a sewage treatment device for water ecological environment governance, including a main body of the sewage treatment device. The outer surface of the lower end of the main body of the sewage treatment device is fixedly connected with a base. The upper surface of the base is fixedly connected with a flocculant introduction pipe. The outer surfaces of the base and the main body of the sewage treatment device are fixedly connected with a support frame. A stirring mechanism is arranged inside the main body of the sewage treatment device. A pretreatment mechanism is arranged at the top of the support frame. A rotating shaft, a stirring cross bar, a fork-shaped stirring rod, a scraper, a support and a scraping blade are arranged inside the main body of the sewage treatment device. A filter box, a fixing plate, a filter plate, a lifting handle and a sewage pipe are arranged at the top of the support frame.

[0004] Through the above technical solution, although the sewage can be introduced into the interior of the filter box through the sewage pipe, and the large-volume sundries and garbage can be filtered through the filter plate. When the filtering effect deteriorates, the lifting handle can be pulled to draw out the filter plate from the inner wall of the filter box. After cleaning or replacing the filter plate, the filter plate can be movably connected to the outer surface of the fixing plate and the inner wall of the filter box, so as to avoid the influence of large-volume sundries on the subsequent treatment of sewage.

[0005] However, it cannot make the flocculant fully contact with the sewage, and at the same time, discharge the impurities formed after the flocculant purifies the sewage and the impurities cleaned from the inner wall of the main body of the sewage treatment device from the main body of the sewage treatment device in time, increasing the filtration burden and reducing the treatment efficiency. Summary of the Utility Model

A bearing is penetrated through both the pretreatment tank and the filtration tank. The first cylinder and the second cylinder are rotatably connected to the pretreatment tank and the filtration tank respectively through the two bearings. A sieve plate installed at the output end of the first cylinder and a water pump for pumping sewage into the filtration tank are provided in the pretreatment tank.

[0009] A filter plate installed at the output end of the second cylinder is provided in the filtration tank. A scraping plate for cleaning the residual impurities on the inner wall of the filtration tank is installed on the filter plate. The scraping plate and the filter plate move in the filtration tank. An electric push rod is installed on the mounting frame, and a cleaning brush for cleaning the filter plate is installed on the electric push rod.

[0010] Further set as, the cleaning brush is composed of a brush plate with an arc-shaped cross-section and a plurality of bristles fixed on the brush plate. A telescopic rod is hinged on the brush plate. The output end of the electric push rod is installed with a connecting pipe inserted with the telescopic rod. A spring fixedly connected to the telescopic rod is installed in the connecting pipe. The telescopic rod moves in the connecting pipe, and the connecting pipe and the output end of the electric push rod are in an L shape.

[0011] Further set as, the cross-section of the sieve plate is V-shaped, and both ends of the sieve plate correspond to the two collection tanks respectively.

[0012] Further set as, a mounting pipe is installed on the filter plate, and the mounting pipe is threadedly connected to the piston rod of the second cylinder.

[0013] By adopting the above technical solutions, the beneficial effects of the present utility model are as follows: When the second cylinder works, it drives the filter plate to move in the filtration tank to disturb the sewage, so that the flocculant is fully contacted with the sewage. At the same time, the filter plate filters the impurities formed by the flocculant purifying the sewage. When the second cylinder works to drive the filter plate to move towards the open end of the filtration tank, the filter plate can be pushed out of the filtration tank. During the process of the filter plate moving out of the filtration tank, the scraping plate cleans the residual impurities on the inner wall of the filtration tank and stays on the filter plate and is removed from the filtration tank together with the filter plate. When the electric push rod works, it drives the cleaning brush to clean the filter plate and clean the impurities on the filter plate into the collection tank, so as to timely discharge the impurities formed after the flocculant purifies the sewage in the filtration tank and the impurities cleaned from the inner wall of the filtration tank together, reduce the filtration burden, and improve the treatment efficiency.

Specific implementation mode

[0018] Refer to Figures 1 to 3 The embodiments of the present utility model will be further described.

[0019] A sewage treatment device for water ecological environment treatment includes a mounting frame 1. A pretreatment tank 2 and a filtration tank 3 that are interconnected through a water pipe 901, a first cylinder 4 and a second cylinder 5 corresponding to the pretreatment tank 2 and the filtration tank 3 respectively, and two collection tanks 6 disposed on both sides of the pretreatment tank 2 are mounted on the mounting frame 1. The two collection tanks 6 are arranged oppositely, and one of the collection tanks 6 is disposed between the pretreatment tank 2 and the filtration tank 3.

[0020] A bearing 7 penetrates through both the pretreatment tank 2 and the filtration tank 3. The first cylinder 4 and the second cylinder 5 are rotatably connected to the pretreatment tank 2 and the filtration tank 3 respectively through the two bearings 7. A sieve plate 8 mounted on the output end of the first cylinder 4 and a water pump 9 for pumping sewage into the filtration tank 3 are provided in the pretreatment tank 2. The water pump 9 pumps the sewage into the filtration tank 3 through the water pipe 901 that connects the pretreatment tank 2 and the filtration tank 3. The cross-section of the sieve plate 8 is V-shaped, and the two ends of the sieve plate 8 respectively correspond to the two collection tanks 6.

[0021] A filter plate 10 mounted on the output end of the second cylinder 5 is provided in the filtration tank 3. A scraping plate 11 for cleaning the residual impurities on the inner wall of the filtration tank 3 is mounted on the filter plate 10. The scraping plate 11 and the filter plate 10 move in the filtration tank 3. An electric push rod 12 is mounted on the mounting frame 1. A cleaning brush 13 for cleaning the filter plate 10 is mounted on the electric push rod 12. The electric push rod 12 drives the cleaning brush 13 to clean the impurities on the filter plate 10 into the collection tank 6 disposed between the pretreatment tank 2 and the filtration tank 3.

[0022] Working principle: Sewage enters the pretreatment tank 2. The large-volume impurities are preliminarily filtered by the sieve plate 8. The first cylinder 4 works to drive the sieve plate 8 to move towards the open end of the pretreatment tank 2, pushing the large-volume impurities filtered out by the sieve plate 8 from the sewage out of the pretreatment tank 2. The cross-section of the sieve plate 8 is V-shaped, which facilitates the large-volume impurities on the sieve plate 8 to fall into the collection boxes 6 on both sides of the pretreatment tank 2. Then, the water pump 9 pumps the preliminarily filtered sewage into the filtration tank 3 through the water pipe 901, and a flocculant is added to the filtration tank 3. After the sewage enters the filtration tank 3, the second cylinder 5 works to drive the filter plate 10 to move in the filtration tank 3 to disturb the sewage, so that the flocculant fully contacts the sewage. At the same time, the filter plate 10 filters the impurities formed by the flocculant purifying the sewage. The second cylinder 5 works to drive the filter plate 10 to move towards the open end of the filtration tank 3, and the filter plate 10 can be pushed out of the filtration tank 3. During the process of the filter plate 10 being removed from the filtration tank 3, the scraper 11 cleans the impurities remaining on the inner wall of the filtration tank 3, and the impurities remain on the filter plate 10 and are removed from the filtration tank 3 along with the filter plate 10. The electric push rod 12 works to drive the cleaning brush 13 to clean the filter plate 10 removed from the filtration tank 3, and the impurities on the filter plate 10 are cleaned into the collection box 6 placed between the pretreatment tank 2 and the filtration tank 3, so as to timely discharge the impurities formed after the flocculant purifies the sewage in the filtration tank 3 and the impurities cleaned from the inner wall of the filtration tank 3 together from the filtration tank 3, reduce the filtration burden, and improve the treatment efficiency.

[0023] The cleaning brush 13 is composed of a brush plate 131 with an arc-shaped cross-section and a number of bristles 132 fixed on the brush plate 131. A telescopic rod 14 is hinged on the brush plate 131. The output end of the electric push rod 12 is provided with a connecting pipe 15 inserted with the telescopic rod 14. A spring 16 fixedly connected with the telescopic rod 14 is installed in the connecting pipe 15. The telescopic rod 14 moves in the connecting pipe 15, and the connecting pipe 15 and the output end of the electric push rod 12 are in an L shape;

[0024] The electric push rod 12 can not only drive the cleaning brush 13 to clean the filter plate 10, and the spring 16 is in its original length state when the cleaning brush 13 cleans the filter plate 10. The electric push rod 12 can also drive the cleaning brush 13 to approach the sieve plate 8. With the brush plate 131 being arc-shaped and hinged with the telescopic rod 14, the cleaning brush 13 will not contact the sieve plate 8 when it moves to the sieve plate 8. And with the telescopic rod 14 moving in the connecting pipe 15 and connected to the connecting pipe 15 through the spring 16, when the electric push rod 12 drives the cleaning brush 13 to move to the sieve plate 8, the spring 16 is compressed so that the bristles 132 contact the sieve plate 8, which is convenient for the cleaning brush 13 to clean the sieve plate 8 removed from the pretreatment tank 2, further cleaning the impurities on the sieve plate 8 into the collection box 6, reducing the filtration burden of the sieve plate 8, and further improving the treatment efficiency.

[0025] An installation pipe 17 is installed on the filter plate 10. The installation pipe 17 is threadedly connected to the piston rod of the second cylinder 5. The filter plate 10 is threadedly connected to the piston rod of the second cylinder 5 through the installation pipe 17, which facilitates the removal of the filter plate 10 when the second cylinder 5 pushes the filter plate 10 out of the filter box 3 for regular in-depth cleaning, further reducing the filtering burden of the filter plate 10 and improving the processing efficiency.

[0026] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of the present invention should be included in the protection scope of the present invention.
