[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0020] Please see Figures 1-5 This embodiment provides a domestic sewage ecological treatment device, including an inlet pipe 1 and a storage tank 2. The storage tank 2 is arranged below the inlet pipe 1. A filter screen 11 is arranged inside the inlet pipe 1. Side plates 12 are symmetrically installed on the front and rear ends of the filter screen 11. A connecting rod 13 is installed on the outer end of the side plate 12. Side seats are symmetrically installed on the front and rear ends of the inlet pipe 1. A side cavity 14 is installed on the upper end of the side seat. A first slider is installed in the side cavity 14 by sliding fit. A damping spring shock absorber 15 is installed at the bottom of the first slider. The connecting rod 13 is installed on the inner end of the first slider. Fixing holes are symmetrically opened at the front and rear of the inlet pipe 1 for connecting... Rod 13 passes through a fixing hole, the diameter of which is larger than the diameter of rod 13. During operation, domestic sewage falls through inlet pipe 1 and passes through filter screen 11 to separate fixed impurities in the sewage. The sewage enters the storage tank 2 through filter screen 11, and the fixed impurities fall onto filter screen 11. When the sewage falls, it causes filter screen 11 to shake up and down. The damping spring shock absorber 15 dampens the filter screen 11 to avoid excessive impact force when the sewage falls, which would cause excessive wear at the connection of filter screen 11 and reduce its service life. When filter screen 11 shakes, it also causes the impurities to shake, thereby preventing the filter screen 11 mesh from becoming clogged and ensuring the filtration effect of sewage.

[0021] A water level sensor 16 is installed on the rear end face of the water storage tank 2. The water inlet pipe 1 is connected to the water storage tank 2 through a fixing frame. An alarm 17 is installed on the front end face of the fixing frame. A control panel 18 is arranged below the alarm 17. The water level sensor 16, the alarm 17 and the control panel 18 are all electrically connected. The control panel 18 is programmed with a PLC to control the operation of each device. When the sewage enters the water storage tank 2, the water level sensor 16 monitors the water level inside the water storage tank 2. When the water level reaches the standard, the control panel 18 controls the alarm 17 to sound an alarm, thereby reminding the staff to deal with it in time without the need for real-time visual observation of the water level.

[0022] A working chamber is arranged on the right side of the water inlet pipe 1. A water pump 19 is installed at the bottom of the working chamber, and a fixed pipe is installed at the bottom of the water pump 19. The other end of the fixed pipe is arranged in the water storage tank 2. A first motor 21 is installed on the upper surface of the working chamber. A main shaft is installed at the output end of the first motor 21. Multiple stirring rods 22 are installed on the outer wall of the main shaft along its circumferential direction. When working, the working chamber is filled with disinfectant. The first motor 21 is started, which drives the stirring rods 22 to rotate, so that the disinfectant is mixed evenly. When the water level reaches the standard, the water pump 19 is turned on, and the disinfectant enters the water storage tank 2 through the fixed pipe, thereby maximizing the disinfection treatment of sewage in the water storage tank 2 and improving the efficiency of disinfection operation.

[0023] A cotton pad 23 is installed on the inner sidewall of the fixing hole along its circumference. When the connecting rod 13 vibrates up and down during operation, the cotton pad 23 provides shock absorption and protection for the connecting rod 13.

[0024] A collection chamber 24 is installed on the upper end face of the side seat. The outer end of the collection chamber 24 is screwed to the side cavity 14 by a fixing screw 25. During operation, when a small amount of sewage is discharged through the fixing hole, the collection chamber 24 collects and treats the sewage to prevent it from flowing into the surrounding environment and causing damage.

[0025] In actual operation, domestic sewage falls through the inlet pipe 1 and passes through the filter screen 11 to separate the fixed impurities in the sewage. The sewage then enters the storage tank 2 through the filter screen 11, and the fixed impurities fall onto the filter screen 11. When the sewage falls, it causes the filter screen 11 to shake up and down. The damping spring shock absorber 15 dampens the filter screen 11 to avoid excessive impact force when the sewage falls, which would cause excessive wear at the connection of the filter screen 11 and reduce its service life. When the filter screen 11 shakes, it also causes the impurities to shake, thereby preventing the filter screen 11 mesh from becoming clogged and ensuring the filtration effect of the sewage.

[0026] Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model. Structures, devices, and operating methods not specifically described and explained in this utility model, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
