Description

Technical Field

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

[0002] The city's sewage pipe system collects all generated sewage and discharges it into nearby rivers for subsequent natural purification or artificial treatment. In this process, a large amount of impurities and fallen leaves are inevitably mixed in. The fallen leaves are naturally fallen off by urban greening trees when the seasons change in autumn, and enter the drainage system through rain or wind. These impurities and fallen leaves mixed in the sewage not only increase the difficulty and cost of sewage treatment plants, but may also cause damage to the ecological environment of the river.

[0003] Application No. 202321538207.5 discloses a sewage treatment device for a river discharge outlet, which relates to the technical field of sewage treatment, and includes a base and a water receiving box, wherein the water receiving box is fixedly connected to the top of the base, a through hole is provided at the bottom of the water receiving box, a rotating rod is movably provided inside the through hole, a plurality of blades are fixedly connected to the rod wall of the rotating rod, a groove is provided inside the base, a motor is provided inside the groove, and the lower end of the rotating rod is fixedly connected to the output end of the motor. The utility model can crush larger impurities entering the water receiving box during the operation of the motor through the rotating rod and the plurality of blades, thereby avoiding the blockage in the river as much as possible, and can drive the two screws to rotate synchronously during the rotation of the sleeve through the meshing connection between the first gear and the two second gears, thereby driving the mounting plate to drive the motor and the rotating rod to reciprocate up and down, thereby achieving effective crushing of impurities.

[0004] The above scheme has shortcomings when used. When the blade crushes the impurities entering the water receiving box, if the sewage contains plastic bags and other debris, it is easy to entangle the blades, which will affect the flow of impurities and may cause blockage. For this reason, we propose a river sewage outlet sewage treatment device to solve the above problem. Utility Model Content

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0019] 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 work belong to the protection scope of the present invention.

[0020] Please refer to Figures 1-3 , in the present invention, a sewage treatment device for a river sewage outlet includes a water tank 1. A drainage hopper 5 is fixedly connected to the back surface of the water tank 1. The drainage hopper 5 can be used to guide sewage, ensuring that garbage enters the water tank 1.

[0021] Hanging plates 6 are fixedly connected to the left and right sides of the water tank 1. A group of mounting holes 4 are opened on the upper surface of each hanging plate 6. The cooperation of the hanging plates 6 and the mounting holes 4 facilitates the installation and fixation of the water tank 1 by the staff.

[0022] A motor 16 is installed on the left side of the water tank 1. The output end of the motor 16 is fixedly connected to a rotating rod 8. The right end of the rotating rod 8 penetrates through the water tank 1 and extends to the outside of the water tank 1. The rotating rod 8 is rotatably connected to the water tank 1. An annularly arranged first crushing knife 15 is fixedly connected to the outer surface of the rotating rod 8. The first crushing knife 15 can be used to crush garbage.

[0023] A protective housing 7 is installed on the outer surface of the motor 16. The right side of the protective housing 7 is connected to the left side of the water tank 1. The protective housing 7 can be used to stably reinforce the motor 16, thus ensuring the stability of the motor 16 during operation.

[0024] The inner wall of the water tank 1 is rotatably connected to a rotating shaft 10. The other end of the rotating shaft 10 penetrates to one side of the water tank 1. The outer surface of the rotating shaft 10 is fixedly connected with annularly arranged second crushing knives 9. The right ends of the rotating shaft 10 and the rotating rod 8 are both fixedly connected with belt pulleys 3. A connecting belt 2 is sleeved on the outer surfaces of the two belt pulleys 3. Through the transmission of the connecting belt 2, the rotating shaft 10 can drive the second crushing knives 9 to rotate to crush the plastic bags.

[0025] The inner bottom wall of the water tank 1 is fixedly connected with equally spaced baffles 13. Each baffle 13 is provided with a group of equally spaced drainage holes 14 on its front surface. When the first crushing knife 15 rotates, it will pass through between the baffles 13, and the baffles 13 can scrape off the plastic bags remaining on the first crushing knife 15, thus avoiding blockage. At the same time, the drainage holes 14 can discharge the sewage.

[0026] The inner bottom wall of the water tank 1 is fixedly connected with an arc-shaped guide plate 12. The top end of the arc-shaped guide plate 12 is fixedly connected with a guide plate 11. The bottom end of the guide plate 11 is connected to the inner bottom wall of the water tank 1. The guide plate 11 can be used to guide the garbage to the second crushing knives 9 for crushing. At the same time, the arc-shaped guide plate 12 can accumulate the un-discharged garbage. When the first crushing knife 15 rotates, it will crush the accumulated garbage again and discharge it.

[0027] The working principle of the present utility model is as follows: When in use, the drainage hopper 5 is connected to the sewage outlet, and then the motor 16 is started to work. The motor 16 will drive the rotating rod 8 to rotate. At the same time, the belt pulley 3 will drive the connecting belt 2 to rotate, and the rotating shaft 10 will also rotate. The guide plate 11 will guide the garbage in the water. The second crushing knives 9 will first crush the garbage. At the same time, the crushed garbage will flow to the first crushing knife 15. The rotating rod 8 will drive the first crushing knife 15 to crush the garbage again. When the first crushing knife 15 rotates and passes through between the baffles 13, the baffles 13 can scrape off the plastic bags wound on the first crushing knife 15, avoiding the influence of plastic bag residues on the water flow, and thus preventing blockage.
