Description

Technical Field

[0001] The utility model relates to the technical field of water treatment equipment, and more specifically, to a drum microfilter. Background Art

[0002] The drum microfilter, also known as the fully automatic drum microfilter, is an environmentally friendly device mainly used for solid-liquid separation and treatment of raw water, circulating water or sewage treatment systems in the early stage of aquaculture. It is based on the principle of microporous filtration and uses a mechanical filtration method to separate suspended matter in the water. The main function of the existing drum microfilter is to remove impurities in the water through filtration. During use, its function is relatively single, especially for the treatment of sewage in aquaculture. Since it can only filter, the odor and harmful bacteria and microorganisms in the water body cannot be treated, so that the existing drum microfilter will diffuse a large amount of odorous gas when treating sewage, causing pollution to the surrounding environment, and a large number of bacteria will remain or breed on the filter drum due to long-term treatment of sewage.

[0029] An ozone generator 8 is fixed on the top of the box cover 3, and an air duct 9 is fixed on the output end of the ozone generator 8, which penetrates the box cover 3 and extends into the box body 2. A drainage pipe 10 arranged parallel to the axis of the filter drum 4 is fixed at one end of the air duct 9 located in the box body 2; a plurality of arc-shaped conduits 11 are equidistantly fixed on the drainage pipe 10, and the arc-shaped conduits 11 are connected to the inner cavity of the drainage pipe 10. A plurality of aeration holes are opened on the outer circumferential surface of the arc-shaped conduits 11 to improve the aeration effect, increase the contact area between ozone and the water body, and improve the sterilization effect on sewage. The plurality of arc-shaped conduits 11 are arranged coaxially with the filter drum 4.

[0030] A drainage pipe 13 connected to the inner cavity of the box body 2 is fixed at the bottom of one end of the box body 2. The water outlet end of the drainage pipe 13 is connected to a return pipe 15 and a water guide pipe 16 through a two-position three-way solenoid valve 14. A lifting pump 17 is installed on the return pipe 15. The water outlet end of the return pipe 15 is connected to the flushing component 5.

[0031] A guide pipe 18 connected to the inner cavity of the sewage pipe 7 is fixed on a section of the outer circular surface of the sewage pipe 7 located inside the filter drum 4. A dirt collection groove 19 arranged along the axial direction of the filter drum 4 is fixed to the top of the guide pipe 18. The dirt collection groove 19 is connected to the guide pipe 18 and cooperates with the filter drum 4. The dirt collection groove 19 is directly opposite to the flushing component 5.

[0032] The flushing assembly 5 includes a main pipe connected to the return pipe 15 , on which are fixed a plurality of flushing pipes penetrating the housing 2 and extending to just above the filter drum 4 , and the water outlet ends of the flushing pipes are directly opposite to the dirt collection tank 19 .

[0033] A liquid level tube 20 is installed on a section of the outer circular surface of the water inlet pipe 6 located outside the box body 2. The liquid level tube 20 is connected to the inner cavity of the water inlet pipe 6. A liquid level sensor 21 is installed on the top of the liquid level tube 20. A control panel 22 is fixed on the outer surface of the box body 2. The control panel 22 is electrically connected to the liquid level sensor 21, the ozone generator 8, and the lifting pump 17.

[0034] The working principle of the drum microfilter provided by the utility model is as follows:

[0035] Working principle: When in use, the sewage to be treated is input through the water inlet pipe 6, and the sewage enters the filter drum 4 through the water inlet pipe 6. The filtered solids passing through the filter drum 4 are retained in the filter drum 4, and the filtered water flows into the bottom of the box body 2. At this time, the ozone generator 8 is started to generate bactericidal ozone, which is sprayed out through the air guide pipe 9 and the drainage pipe 10 by the arc guide 11, and the filtered water is deodorized, disinfected and sterilized. Finally, the treated water enters the water guide pipe 16 through the drain pipe 13 and the two-position three-way solenoid valve 14, and is finally discharged from 16 to achieve the filtration of sewage.

[0036] When the filter drum 4 is blocked, the water input through the water inlet pipe 6 cannot be filtered in time, so that the water pressure in the water inlet pipe 6 increases, thereby increasing the water level in 20. When the liquid level sensor 21 detects the water level, the control panel 22 controls the lift pump 17 to extract the filtered water inside the box body 1, and the filter drum 4 is rinsed by the flushing component 5 (at this time, the filter drum 4 rotates driven by the external motor). The impurities adhered to the inner wall of the filter drum 4 during the flushing will directly fall into the dirt collection tank 19, and finally discharged into the filter cone 12 through the guide pipe 18 and the sewage pipe 7. The water filtered by the filter cone 12 flows into the water guide pipe 16 again, reducing the waste of water resources.

[0037] Embodiment 2:

[0038] Based on the specific embodiment 1, the difference of this embodiment is that:

[0039] like Figure 8 , 6 As shown, a filter cone 12 connected to the inner cavity of the sewage pipe 7 is fixed at the discharge end of the sewage pipe 7, a plurality of filter screens are fixed from top to bottom in the filter cone 12, a cleaning box door is provided on the filter cone 12, and the water guide pipe 16 is connected to the water outlet end at the bottom of the filter cone 12. Impurities enter the filter cone 12 along with the water flow, and since multiple layers of filter screens are provided in the filter cone 12, the impurities can be intercepted again to remove impurities in the sewage, and the provision of the cleaning box door facilitates the cleaning of the inside of the filter cone 12 at a later time.

[0040] The above are only specific embodiments of the utility model, but the technical features of the utility model are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the utility model to solve basically the same technical problems and achieve basically the same technical effects are all included in the protection scope of the utility model.
