[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figure 1-4As shown, this utility model provides a technical solution: a sewage treatment sedimentation tank, including a tank body 1, which is used to store sewage and ensure that the sewage can be sedimented inside. An inner spiral water inlet pipe 2 is provided on the top surface of the tank body 1, which guides the sewage into the tank body 1 and simultaneously imparts an initial velocity to the sewage to accelerate the sedimentation of impurities. An inlet pipe 3 is provided on the top surface of the inner spiral water inlet pipe 2, which is used to connect to a sewage supply device to ensure that the sewage can enter the device. A chemical inlet pipe 4 is provided on the top surface of the inner spiral water inlet pipe 2, which is used to add chemicals to ensure that the sewage impurities inside the tank body 1 can be fully sedimented. An inclined plate 5 is provided inside the tank body 1 to assist the tank body 1 and ensure that small particles in the sewage can be quickly sedimented. A sedimentation funnel 6 is provided on the bottom surface of the tank body 1 to accumulate sediment sludge, facilitating quick cleaning of the sediment sludge by staff. A filter drain pipe 7 is provided on one side of the tank body 1. The filter drain pipe 7 is used to discharge the settled wastewater and filter it again. A transparent glass 8 is provided on one side of the tank 1 to facilitate the observation of the sedimentation inside the device by the staff, so that the sludge can be cleaned in time when there is too much. The spiral inlet pipe 2 is equipped with a spiral inclined plate 9 inside. The spiral inclined plate 9 is used to guide the wastewater into the tank 1 and to give the wastewater an initial velocity to accelerate the sedimentation of impurity particles. A sealing cover 10 is provided on the top surface of the inlet pipe 3 to seal the inlet pipe 3 and ensure that the inside of the tank 1 is closed during the sedimentation process. A slanted insert plate 11 is provided on one side of the ramp plate 5. The slanted insert plate 11 is used to cooperate with the insertion slot 12 to ensure that the ramp plate 5 can be firmly fixed inside the tank 1. The top side of the slanted insert plate 11 is fixedly connected to the top side of the ramp plate 5 to ensure that the slanted insert plate 11 and the ramp plate 5 are integrated and that the ramp plate 5 can be firmly fixed to one side of the inner wall of the tank 1.

[0021] The interior of the housing 1 is provided with a slot 12 for use with the inclined insertion plate 11, ensuring that the inclined plate 5 can be firmly fixed inside the housing 1. A support rod 13 is provided on the bottom surface of the housing 1 to support the entire device and ensure that the device is not affected by external forces during use. A threaded connecting ring 14 is provided on the top surface of the sedimentation funnel 6, which connects the sedimentation funnel 6 to the bottom of the housing 1, ensuring a tight connection between the sedimentation funnel 6 and the housing 1. The outer circular wall is provided with a rubber ring 15, which is used to contact the bottom surface of the tank 1 to ensure that there is no water leakage at the connection between the sedimentation funnel 6 and the tank 1. The bottom surface of the sedimentation funnel 6 is provided with a sludge discharge pipe 16, which is used to discharge the sludge inside the sedimentation funnel 6 to ensure that the settled sludge does not accumulate too much and affect the discharge of treated wastewater. The bottom surface of the sludge discharge pipe 16 is provided with a bottom sealing cover 17, which is used to seal the sludge discharge pipe 16 to ensure that the inside of the tank 1 is in a closed state during the sedimentation process.

[0022] Working principle: The staff first removes the sealing caps 10 from the water inlet pipe 3 and the chemical inlet pipe 4, then connects the water inlet pipe 3 to the sewage supply device, allowing the sewage to enter the inner spiral water inlet pipe 2 and then into the tank 1. At the same time, a settling agent is added, and then the water inlet pipe 3 and the chemical inlet pipe 4 are sealed with the sealing caps 10, allowing the sewage to settle inside the tank 1. When smaller particles of impurities adhere to the inner wall of the tank 1, they will slide down the ramp plate 5 and accumulate inside the sedimentation funnel 6. After sedimentation, the treated sewage is discharged through the filter drain pipe 7. The staff can then observe the thickness of the sedimentation funnel 6 through the transparent glass 8 to determine whether cleaning is necessary. If cleaning is required, the bottom sealing cap 17 can be removed to drain the sludge. When there is too much strongly attached sludge, the ramp plate 5 and the sedimentation funnel 6 are removed for a thorough cleaning of the inside of the tank 1 to ensure the efficiency of the sewage sedimentation treatment inside the tank 1 in the next cycle.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
