[0024] In order to more clearly understand the technical means of the utility model and implement it according to the contents of the specification, the specific implementation methods of the utility model are further described in detail below in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model. Example

[0025] like Figures 1 to 5 As shown, the utility model provides a portable low-pressure sewage treatment device, including a movable shell 1 and a sewage treatment area 2 opened in the shell 1, a sewage treatment module is arranged in the sewage treatment area 2, an exhaust fan 3 is fixedly connected to the outside of the sewage treatment area 2, a vent is arranged on one side of the sewage treatment area 2, the vent is located above the liquid surface of the sewage treatment area 2, an air inlet end of the exhaust fan 3 is connected to the vent, the sewage treatment module includes a solid-liquid separation box 4, the solid-liquid separation box 4 is connected to the outside through a feed pipe 5, and the solid-liquid separation box 4 is connected to the sewage treatment area 2 through a plurality of filter holes 6.

[0026] like Figures 1 to 5 As shown, a control area 7 is also provided in the shell 1, and the control area 7 and the sewage treatment area 2 are separated by a partition 8, and a vent is provided on the partition 8. The exhaust fan 3 is located in the control area 7, and an air inlet pipe 9 and an air outlet pipe 10 are provided on the exhaust fan 3. The air inlet pipe 9 is connected with the vent, and the air outlet pipe 10 is connected with the outside. A battery 11 for powering the exhaust fan 3 is also provided in the control area 7. The battery 11 adopts a 48-volt low-voltage lead-acid battery 11, and does not require an external power supply or air pipe. It is easy to move and has a higher safety factor. The power consumption is lower than that of directly connecting to an external pneumatic device.

[0027] The exhaust fan 3 is powered by the battery 11 in the control area 7, so that the exhaust fan 3 can extract the air in the sewage treatment area 2 through the air inlet pipe 9, and because the sewage treatment area 2 is connected with the solid-liquid separation box 4 and then connected to the outside through the feed pipe 5, after the air in the sewage treatment area 2 is extracted, the air in the solid-liquid separation box 4 and the air in the feed pipe 5 will flow into the sewage treatment area 2 in sequence, thereby forming an air flow channel to generate suction, so that the feed pipe 5 can absorb sewage into the solid-liquid separation box 4, and the several filter holes 6 on the solid-liquid separation box 4 will filter the solids in the sewage and retain them therein, and then the remaining sewage can flow into the sewage treatment area 2 and be treated by the sewage treatment module. Because the ventilator opened on the partition 8 is located above the liquid level of the sewage in the sewage treatment area 2, the suction of sewage can be avoided as much as possible while generating suction.

[0028] like Figures 1 to 5As shown, the sewage treatment module also includes an oil drainage component, which includes an oil floating collection plate 12, a diaphragm pump 13 and an oil-water separation box 14. The material density of the oil floating collection plate 12 is less than the density of water. The oil floating collection plate 12 is provided with a plurality of grooves distributed in an array. The oil floating collection plate 12 is connected to the diaphragm pump 13 through a hose 15. The diaphragm pump 13 and the oil-water separation box 14 are both fixedly connected to the inner wall of the sewage treatment area 2. The oil-water separation box 14 is divided into an oil drainage groove 18 and a drainage groove 19 through a fixing plate 17. The liquid outlet end of the diaphragm pump 13 is arranged toward the oil drainage groove 18. The oil drainage groove 18 is connected to the outside through an oil drainage pipe 16. A reflux pipe 20 is provided in the drainage groove 19 and passes through the bottom surface thereof. The inlet height of the reflux pipe 20 is 1.5 mm lower than the inlet height of the oil drainage pipe 16.

[0029] By allowing the oil floating collection plate 12 to float on the sewage, it can move up and down with the liquid level of the sewage treatment area 2. When the diaphragm pump 13 is started, the diaphragm pump 13 can generate suction to the inside of the oil floating collection plate 12 through the hose 15, so as to absorb the oil floating in the upper layer of the sewage into the hose 15 and discharge it into the oil drain groove 18 of the oil-water separation box 14. In this process, the grooves on the oil floating collection plate 12 can facilitate the oil floating in the sewage to enter the oil floating collection plate 12. After the oil floating enters the oil drain groove 18, it can be discharged from the shell 1 through the oil drain pipe 16. However, in the process of absorbing the oil floating, the oil floating collection plate 12 will inevitably suck in a lot of sewage, and as the liquid level increases, the oil floating will gradually increase. As the amount of floating oil decreases, the possibility of sucking in sewage will gradually increase. Therefore, when a large amount of sewage at the top of the liquid surface enters the oil-water separation box 14 along the hose 15, the first sucked in floating oil will fill the oil drain groove 18 and be discharged along the oil drain pipe 16. As the amount of sucked sewage increases, the liquid level in the oil-water separation box 14 will exceed the fixed plate 17, and the sewage will enter the drain groove 19. At this time, due to density reasons, the sewage below the floating oil will flow from the return pipe 20 to the bottom of the sewage treatment area 2 again to complete the oil-water separation. Moreover, because the inlet height of the return pipe 20 is lower than the inlet height of the oil drain pipe 16, it can further ensure that the sewage leaks downward first, and the floating oil is discharged toward the oil drain pipe 16 at the same time.

[0030] In this embodiment, the floating oil collecting tray 12 can also be made of a stainless steel plate, and a foam plate is arranged at the bottom thereof to make it float on the water surface.

[0031] like Figures 1 to 5As shown, the sewage treatment module also includes a drainage component, which includes a submersible pump 21 and a drain pipe 22. The water outlet end of the submersible pump 21 is connected to the drain pipe 22, and the end of the drain pipe 22 away from the submersible pump 21 is connected to the outside world. The oil drain pipe 16 and the drain pipe 22 are both provided with a ball valve 23. The sewage at the bottom of the sewage treatment area 2 is absorbed by the submersible pump 21 and discharged into the shell 1 along the drain pipe 22, and the ball valve 23 on the oil drain pipe 16 and the drain pipe 22 can play a good sealing effect, so that when the exhaust fan 3 is started, no suction will be generated at the oil drain pipe 16 and the drain pipe 22.

[0032] like Figures 1 to 5 As shown, the sewage treatment module also includes a collecting box 24, a filter cartridge 25 and an oscillator 26. The oscillator 26 is fixedly connected to the outer peripheral wall of the solid-liquid separation box 4. The collecting box 24 is fixedly connected to the outer bottom surface of the solid-liquid separation box 4. The solid-liquid separation box 4 is connected to the interior of the collecting box 24 through a plurality of filter holes 6. A liquid outlet is provided on the bottom surface of the collecting box 24. The filter cartridge 25 is located below the liquid outlet. The inner bottom surface of the solid-liquid separation box 4 is inclined and a plurality of filter holes 6 are located at the bottom of the inner bottom surface. One end of the solid-liquid separation box 4 having a plurality of filter holes 6 is connected to the outside and is provided with a solid material outlet window 27.

[0033] The oscillator 26 makes the sewage and iron filings in the solid-liquid separation box 4 move downward along the inner bottom surface of the solid-liquid separation box 4 and accelerate the separation and filtration speed. The collection box 24 collects the sewage filtered by a plurality of filter holes 6 and discharges it into the filter cartridge 25 for filtration again to prevent the fine iron filings from damaging the drainage components and oil discharge components in the sewage treatment area 2. After the solid-liquid separation is completed, the solid material outlet window 27 can be opened to remove the solid waste such as the iron filings.

[0034] like Figures 1 to 5 As shown, when the sewage treatment device is used for sewage treatment, the battery 11 supplies power to the exhaust fan 3, so that suction is generated at the feed pipe 5 to absorb sewage and iron filings mixed in the sewage, and the sucked sewage is filtered through the solid-liquid separation box 4 and the filter cartridge 25, and solid impurities such as iron filings are retained in the solid-liquid separation box 4 and the filter cartridge 25. The sewage flows to the bottom of the sewage treatment area 2, and the oil discharge component separates the floating oil on the sewage from the sewage and discharges it into the shell 1, and the drainage component discharges the remaining sewage into the shell 1, thereby completing the treatment of the sewage, and the treated sewage can also be sucked into the sewage treatment area 2 in the shell 1 again for circulation treatment to ensure the oil-water separation effect of the discharged liquid.

[0035] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
