DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention.

[0029] Reference Figure 1-Figure 5 A mobile domestic sewage treatment and purification device includes a base 1, a control cabinet 18 is installed at one end of the top of the base 1, and a controller is arranged in the control cabinet 18. In actual use, the controller is one of a PLC logic controller, a control host, and a control mainboard; and in order to ensure the normal operation of the purification device, a battery pack is also arranged in the control cabinet 18. The battery pack is connected to the controller through a wire to provide power for the purification device, so that the purification device can be used without an external power supply, thereby improving the adaptability of the purification device for outdoor use.

[0030] A sewage treatment tank 2 is arranged on the top of the base 1, wherein Figure 1 and Figure 4 As shown, a water pump 3 is installed on the top of the sewage treatment tank 2, and the water pump 3 is connected to the controller through a wire. The inlet of the water pump 3 is connected to a water pumping pipe 4, and the outlet of the water pump 3 is connected to a water outlet pipe 5. The other end of the water outlet pipe 5 is placed at one end inside the sewage treatment tank 2 and connected to a water distribution pipe 6. When the water pump 3 is in operation, the sewage will be pumped to the water outlet pipe 5 by the water pumping pipe 4 and sent to the sewage treatment tank 2;

[0031] The sewage entering the sewage treatment box 2 will fall downward from the water distribution pipe 6 in a dispersed manner. At least two frames 7 are arranged at the upper end of the sewage treatment box 2. The frames 7 are arranged staggered and tilted from top to bottom. A sieve plate 10 is arranged in the frame 7, and the top of the sieve plate 10 located at the top corresponds to the water distribution pipe 6. The sewage can be filtered to remove large particles of debris in the sewage. A plurality of hooks 11 are installed on the top surface of the sieve plate 10 and are arranged at intervals and bent toward the top of the sieve plate 10. When the sewage slides along the sieve plate 10, the packaging bags and other debris mixed in the sewage will be hooked by the hooks 11. In order to prevent packaging bags and other debris from continuing to fall, the top of the frame 7 is set on the first limit seat 8, and the side of the first limit seat 8 is fixed to the inner wall of the sewage treatment tank 2, and the bottom of the frame 7 is on the second limit seat 9, and a gap is left between the side of the second limit seat 9 and the inner wall of the sewage treatment tank 2, and the end of the second limit seat 9 is fixed to the inner wall of the sewage treatment tank 2, so that there is sufficient space between adjacent sieve plates 10, so that the sewage can completely fall from one sieve plate 10 to the next sieve plate 10; and the setting of multiple sieve plates 10 also ensures that the sewage can be fully filtered by the sieve plates 10.

[0032] An activated carbon plate 12 is arranged below the frame 7, and both sides of the activated carbon plate 12 are arranged on the third limit seat 13, and the side of the third limit seat 13 is fixed to the inner wall of the sewage treatment box 2, so that harmful substances are adsorbed on the filtered sewage, thereby purifying the sewage; the bottom of the sewage treatment box 2 is inclined, and a drain pipe 14 is installed on the bottom of one side of the sewage treatment box 2, and finally the water purified by the activated carbon plate 12 will be discharged from the drain pipe 14.

[0033] Specifically, an inlet and outlet 15 is opened on one side of the sewage treatment box 2, and a sealed door 16 is hinged on one side of the inlet and outlet 15. The other side of the sealed door 16 is connected to the sewage treatment box 2 through a lock. When the sewage does not need to be treated, the sealed door 16 can be opened to replace and clean the sieve plate 10 and the activated carbon plate 12; and because the sieve plate 10 and the activated carbon plate 12 are placed and supported by a limit seat, the replacement and cleaning operations of the sieve plate 10 and the activated carbon plate 12 are also convenient.

[0034] like Figure 2 and Figure 5 As shown, a driving shaft 19 is arranged parallel to the bottom of the base 1, and a driving mechanism for driving the driving shaft 19 is installed on the driving shaft 19 to drive the driving shaft 19 to rotate.

When turning during the movement process is required, the pushing device 36 can drive the two second support shafts 33 to rotate in the same direction, thereby realizing the turning operation during the movement of the purification device.

[0038] Specifically, in actual use, the pushing device 36 is one of an electric push rod and a cylinder, and the two pushing devices 36 independently control the two second support shafts 33 respectively, so that the rotation of the second support shafts 33 is more labor-saving and more efficient.

[0039] An armrest 17 is installed at one end of the top of the base 1 away from the driving wheel 23, and a control button is provided on the armrest 17. The control button is connected to the controller through a wire. When the purification device needs to be moved, the operator can hold the armrest 17 and then control the driving motor 27 and the pushing device 36 through the control button, thereby realizing the moving operation of the purification device.

[0040] Furthermore, in order to ensure the supporting stability of the drive shaft 19, a second support seat 30 is installed on the first connecting shaft 29, and the top of the second support seat 30 is fixed to the base 1, thereby providing support for the second support shaft 33 and the first connecting shaft 29, which not only reduces the force on the pushing device 36, but also ensures the stability of the entire drive shaft 19.

[0041] In order to improve the stability of the second support shaft 33 when the purification device is turned, Figure 5 As shown, an arc-shaped guide rail 39 is arranged above the second connecting seat 34, and the center of the guide rail 39 corresponds to the rotation axis of the first connecting seat 31, and a slider 41 is slidably installed on the guide rail 39, and a connecting rod 40 is connected to the slider 41.
