[0002] A microfilter is a screen filter that intercepts fine suspended solids. Its main structure includes a cylindrical metal frame. The rotating drum rotates around the central axis and is attached with a working net woven from stainless steel wires, which is used for filtering and removing plankton such as algae and water fleas, and is applicable to the treatment of fishery sewage, etc.

[0003] During the process of water treatment using some existing microfilters, a large amount of odor is generated inside and directly discharged into the atmosphere, which does not meet the environmental protection requirements. Secondly, the filter mesh holes on the filter cylinder are prone to blockage. The existing method is to backwash with high-pressure water flow to flush the mesh holes, but over time, it is difficult to clean the filter mesh holes again.

[0004] Therefore, the utility model provides a microfilter device to solve the above problems. Summary of the Utility Model

[0016] Beneficial effects:

[0017] The utility model provides a micro-filter device. Compared with the prior art, the following beneficial effects are achieved:

[0018] (1) For a micro-filter device, the air discharged through the holes on the air diffuser pipe is discharged into the water, and the bubbles can enter its pores. When the bubbles contact an object, they burst, generating a tiny mechanical impact. Through the mechanical impact, the stains and impurities in the filter holes on the filter cylinder are removed, facilitating the cleaning of the stains on the filter cylinder.

[0019] (2) For a micro-filter device, by injecting air or oxygen into the water body in the form of bubbles, the dissolved oxygen content in the water body is effectively increased, which can significantly improve the microbial degradation efficiency and reduce the residue of organic matter in the water body.

[0020] (3) For a micro-filter device, the bubbles generated by the air diffuser pipe cause a large amount of gas to be generated inside the housing, expelling the odor generated inside the housing. Then, when the air pump is started, the odor passes through the filter pipe, and the activated carbon in the filter pipe adsorbs the malodorous substances such as fishy smell, and then is discharged through the exhaust hole. After treating the odor by the activated carbon adsorption method, the odor of the discharged gas is greatly reduced, which is beneficial to environmental protection.

[0021] (4) For a micro-filter device, through the arranged activated carbon, after adsorption saturation, its adsorption performance can be restored through regeneration treatment, realizing circular use, which is economical and applicable. Description of the drawings

[0037] The housing 1 is provided with a water inlet 42, a sewage outlet 43 and a drain outlet 44. The water inlet 42 is arranged at the side end of the housing 1, the sewage outlet 43 is arranged at the bottom end of the housing 1, and the drain outlet 44 is arranged at the side end of the housing 1. A filter cylinder 45 is arranged inside the housing 1, and a sewage pipe is arranged inside the filter cylinder 45.

[0038] The sewage filtering mechanism further includes a water pipe 46 and a water joint 47. The water pipe 46 is arranged on the side wall of the housing 1, and the water joint 47 is arranged on the water pipe 46.

[0039] Working process: Start the drive motor set 41, drive the filter cylinder 45 to rotate through the rotating shaft, introduce sewage into the water inlet 42, the water flow enters the filter cylinder 45 through the pipeline, the water flow passes through the filtration of the filter cylinder 45, flows to the bottom of the housing 1, and then is discharged through the drain outlet 44. When the filter cylinder 45 is blocked, the filter cylinder 45 rotates, water is introduced into the water pipe 46, and the water flow passes through the water joint 47 to wash the filter cylinder 45, so that the stains on the filter cylinder 45 and the large impurities inside the filter cylinder 45 are washed into the sewage pipe and then discharged through the sewage outlet 43.

[0040] Embodiment Two:

[0041] Please refer to Figure 1-7 , on the basis of Embodiment One, this embodiment provides a technical solution for a micro-filter device: The aeration mechanism includes a main air pipe 51, and the main air pipe 51 is arranged at the bottom end inside the housing 1.

[0042] The main air pipe 51 is communicated with a branch air pipe 52, and the branch air pipe 52 is arranged at the bottom end inside the housing 1.

[0043] The side end of the branch air pipe 52 is threadedly connected with an aeration pipe 53.

[0044] Working process: Discharge gas from the main air pipe 51, the gas passes through the branch air pipe 52 and is conveyed to the aeration pipe 53.

When the air bubbles contact an object, they burst, generating a tiny mechanical impact. Through the mechanical impact, the stains and impurities in the filter holes on the filter cylinder 45 are removed to facilitate the cleaning of the stains on the filter cylinder 45. Secondly, by injecting air or oxygen into the water body in the form of air bubbles, the dissolved oxygen content in the water body is effectively increased, which can significantly improve the microbial degradation efficiency, reduce the residue of organic matter in the water body, so that the filtered water after cleaning is discharged into the fishery pond, reducing the breeding of germs, providing a more suitable living environment for aquatic products, avoiding problems such as slow growth and increased mortality of aquatic organisms due to lack of oxygen in aquatic organisms.

[0048] The gas filtering mechanism further includes an exhaust hole 63. The exhaust hole 63 is opened on the maintenance cover 2, and the outlet of the air pump 62 is communicated with the exhaust hole 63.

[0049] Working process: The bubbles generated by the aeration tube 53, on the one hand, increase the oxygen content in the water, and on the other hand, generate a large amount of gas inside the housing 1, expelling the odor inside the housing 1. Then the air pump 62 is started, so that the odor passes through the filter tube 61, and the activated carbon in the filter tube 61 adsorbs malodorous substances such as fishy smell, and then is discharged through the exhaust hole 63. After treating the odor by the activated carbon adsorption method, the odor of the discharged gas is greatly reduced, which is beneficial to environmental protection. Moreover, after the activated carbon is saturated in adsorption, its adsorption performance can be restored through regeneration treatment to achieve cyclic use, which is economical and applicable.
