It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0021] As Figures 1 - 3 shown, a spiral domestic sewage treatment device includes a water storage device 1 and a separation device 2. The separation device 2 is arranged inside the water storage device 1 to separate and discharge the garbage in the sewage. Its characteristic is that the separation device 2 is provided with a squeezing device 3 for squeezing the moisture in the garbage immediately, and a drainage device 4 is sleeved outside the separation device 2.

[0022] The sewage is collected by the water storage device 1, and then the separation device 2 guides the sewage in the water storage device 1 into the inside of the separation device 2 for liquid-solid separation. The separated garbage is stored inside the separation device 2 and then is squeezed by the squeezing device 3 to discharge the drainable sewage in the garbage and then discharged. The drainage device 4 discharges the sewage separated without garbage.

[0023] Among them, as Figures 1 - 3 shown, the separation device 2 is equipped with a supporting servo motor.

[0024] Among them, as Figures 1 - 3 shown, the water storage device 1 includes a water storage tank 1-1 and a water storage chamber 1-2. A water storage chamber 1-2 for collecting domestic sewage is arranged inside the water storage tank 1-1, and the separation device 2 is arranged inside the water storage tank 1-1 and communicated with the water storage chamber 1-2.

[0025] Among them, as Figures 1 - 3As shown in the figure, the separation device 2 includes a fixed cylinder 2-1, an inlet hole 2-2, a water outlet hole 2-3, a rotating shaft 2-4, a spiral push plate 2-5, and a garbage discharge hole 2-6. The fixed cylinder 2-1 is arranged inside the water storage tank 1-1. The fixed cylinder 2-1 is communicated with the water storage cavity 1-2 through the inlet hole 2-2. The water outlet hole 2-3 is arranged on the fixed cylinder 2-1 and is communicated with the inside of the fixed cylinder 2-1. The rotating shaft 2-4 is arranged inside the fixed cylinder 2-1. The spiral push plate 2-5 is arranged on the rotating shaft 2-4 and is inside the fixed cylinder 2-1. The garbage discharge hole 2-6 is arranged at the upper end of the fixed cylinder 2-1. The rotating shaft 2-4 is equipped with a supporting motor. The extrusion device 3 seals the garbage discharge hole 2-6. A drainage device 4 is sleeved outside the fixed cylinder 2-1.

[0026] The rotating rotating shaft 2-4 drives the spiral push plate 2-5 to rotate. The rotating spiral push plate 2-5 pushes the sewage and garbage into the inside of the fixed cylinder 2-1 through the inlet hole 2-2. Then the sewage will be discharged into the drainage device 4 through the water outlet hole 2-3. The garbage will continue to move upward to the upper end of the fixed cylinder 2-1 for accumulation. The extrusion device 3 and the rotating spiral push plate 2-5 squeeze the garbage to discharge the sewage in the garbage and then discharge the garbage.

[0027] Among them, as Figures 1 - 3 shown, the fixed cylinder 2-1 and the garbage discharge hole 2-6 are connected by a conical surface 2-7.

[0028] The conical surface 2-7 enables the garbage to move towards the center after being squeezed, facilitating the extrusion and discharge of the garbage.

[0029] Among them, as Figures 1 - 3 shown, the extrusion device 3 includes a connecting rod 3-1, a fixed column 3-2, a fixed disk 3-3, a sliding groove 3-4, a limiting spring 3-5, a limiting ball 3-6, an arc groove 3-7, a cavity column 3-8, and a spring 3-9. The fixed column 3-2 is arranged on the fixed cylinder 2-1 through the connecting rod 3-1. The fixed disk 3-3 is arranged on the fixed column 3-2. The cavity column 3-8 slides on the fixed disk 3-3. The cavity column 3-8 seals the garbage discharge hole 2-6. A sliding groove 3-4 for accommodating the limiting ball 3-6 is arranged inside the fixed disk 3-3. A limiting spring 3-5 is arranged between the sliding groove 3-4 and the limiting ball 3-6. The arc groove 3-7 is arranged inside the cavity column 3-8. The arc groove 3-7 and the limiting ball 3-6 cooperate to limit the movement of the cavity column 3-8. An arc groove 3-7 is arranged between the cavity column 3-8 and the fixed disk 3-3.

[0030] When the cavity column 3-8 is squeezed by the garbage, the fixed disk 3-3 hinders the movement of the cavity column 3-8 through the cooperation between the limiting spring 3-5, the limiting ball 3-6 and the arc-shaped groove 3-7, so that the pressure on the garbage increases to squeeze out more sewage. When the garbage is compressed to a certain extent, the reaction force exerted by the garbage on the fixed disk 3-3 breaks through the limitation between the limiting spring 3-5, the limiting ball 3-6 and the arc-shaped groove 3-7, and then the cavity column 3-8 moves upward to open the garbage discharge hole 2-6 for discharging the garbage. The spring 3-9 can prevent the pressure between the cavity column 3-8 and the spiral push plate 2-5 from decreasing, so as not to affect the extrusion of sewage from the garbage.

[0031] Among them, as Figures 1 - 3 shown, the drainage device 4 includes a sleeve 4-1, a lead-out cavity 4-2 and a lead-out pipe 4-3. The sleeve 4-1 is sleeved on the fixed cylinder 2-1 to wrap the water outlet hole 2-3. A lead-out cavity 4-2 is provided between the sleeve 4-1 and the fixed cylinder 2-1, and a lead-out pipe 4-3 is provided at the lower end of the sleeve 4-1.

[0032] It can be understood that the present invention is described through some embodiments. Those skilled in the art know that without departing from the spirit and scope of the present invention, various changes or equivalent replacements can be made to these features and embodiments. In addition, under the teaching of the present invention, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application belong to the scope protected by the present invention.
