Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-4 , a sewage treatment device provided by the present invention includes a sedimentation tank 1, a funnel stirring tank 2 fixed on the outer wall of one side of the sedimentation tank 1, and a cover plate 3 fixed on the tops of the sedimentation tank 1 and the funnel stirring tank 2. A stirring and dredging mechanism is provided in the funnel stirring tank 2, and a water outlet 4 is opened on one side of the funnel stirring tank 2. A filtering mechanism is provided on one side of the water outlet 4 in the sedimentation tank 1. The filtering mechanism includes a discharge port 501 opened on the top of the cover plate 3 on one side of the water outlet 4. The cover plate 3 is connected with an installation frame 502 through a lifting mechanism, and filter screens 503 are fixed on the inner walls of the opposite sides of both sides of the installation frame 502. Through the lifting mechanism and the filtering mechanism, the suspended matter in the sewage can be cleaned and the suspended matter in the sewage can be taken out of the sewage;

[0022] The lifting mechanism includes a threaded rod 701 whose bottom end is rotatably connected to the inner wall of the bottom of the sedimentation tank 1. A guide rod 702 is inserted into the discharge port 501, and the bottom end of the guide rod 702 is fixed on the inner wall of the bottom of the sedimentation tank 1. An installation hole is opened on one side of the installation frame 502, and the guide rod 702 is inserted through the installation hole. The threaded rod 701 is screwed with the installation frame 502, and the threaded rod 701 is connected with a driving mechanism. By driving the threaded rod 701 to rotate through the driving mechanism, the installation frame 502 and the filter screen 503 can be driven to rise out of the device, facilitating personnel to clean the filter screen 503;

[0023] The driving mechanism includes a U-shaped bracket 901 fixed to the top of the cover plate 3 located above the discharge port 501. One outer wall of the top side of the U-shaped bracket 901 is fixed with a first servo motor 902. One end of the rotating shaft of the first servo motor 902 is fixed to the top end of the threaded rod 701. The top end of the guide rod 702 is fixed to the inner wall of the bottom of the other side of the U-shaped bracket 901. During use, the first servo motor 902 drives the threaded rod 701 to rotate, driving the installation frame 501 to rise and fall. In this way, the installation frame 501 can be used to block sewage from entering the sedimentation tank 1, and at the same time, sewage can flow into the sedimentation tank 1 through the filter screen 502, improving the collection efficiency of suspended matter.

[0024] The stirring and dredging mechanism includes a second servo motor 801 fixed to the top of the cover plate 3 located above the funnel stirring tank 2. One end of the rotating shaft of the second servo motor 801 is fixed with a transmission shaft 802. Multiple groups of stirring rods 803 are provided on the side wall of the transmission shaft 802, and the number of each group of stirring rods 803 is two. The other ends of each group of stirring rods 803 are fixed with scraping plates 804. By driving the transmission shaft 802 to rotate through the second servo motor 801, the stirring rods 803 and the scraping plates 804 are driven to rotate, which can fully mix the medicine and sewage, achieving the first-step sedimentation treatment. At the same time, during the rotation of the scraping plate 804, sludge is prevented from adhering to the inner wall of the funnel stirring tank, facilitating sludge cleaning and improving the sewage treatment efficiency of the device.

[0025] The cover plate 3 is provided with a water inlet above the funnel stirring tank 2. The other side of the sedimentation tank 1 is provided with a drain port 10. A baffle 6 is fixed to the inner wall of the sedimentation tank 1 on one side of the installation frame 502, and the size of the installation frame 502 is larger than the size of the water outlet 4. The baffle 6 divides the sedimentation tank 1 into two sedimentation areas. The sewage after the first treatment will flow into the sedimentation tank 1 from the water outlet 4, and the sewage for further sedimentation will flow into the next sedimentation area from above the baffle 6, and finally flow out as clean water, improving the sewage purification efficiency.

[0026] Working principle: During use, the sewage will first be filled into the funnel stirring tank 2, and then by adding medicine and so on, the second servo motor 801 is used to drive the transmission shaft 802 to rotate, thereby driving the stirring rods 803 to stir, fully mixing the medicine and sewage, achieving the first-step sedimentation treatment. At the same time, during the rotation of the scraping plate 804, sludge is prevented from adhering to the inner wall of the funnel stirring tank 2, facilitating sludge cleaning and improving the sewage treatment efficiency of the device.

[0027] At the same time, the already sedimented sewage will enter the installation frame 501 of the sedimentation tank 1 from the water outlet 10. The suspended matter in the sewage is collected through the filtering action of the filter screen 502. By driving the threaded rod 702 to rotate using the first servo motor 701, the installation frame 502 and the filter screen 503 can be driven to rise and be exported outside the device, facilitating personnel to clean the filter screen 503 and greatly facilitating personnel to clean the collected suspended matter, improving the practicability of the device.

[0028] Meanwhile, the installation frame 501 blocks the water outlet 10 to prevent sewage from flowing into the sedimentation tank 1. The sewage that enters the sedimentation tank 1 will be separated and sedimented by the baffle 6 and finally flow out of the device.

[0029] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.
