Description

Technical Field

[0001] This utility model relates to the field of microfiltration technology, specifically a drum-type microfiltration machine. Background Technology

[0002] Aquaculture is the process by which humans utilize aquatic waters available for aquaculture (including planting) to raise aquatic economic animals and plants according to the ecological habits of the aquatic organisms and their requirements for aquatic environmental conditions, using aquaculture technologies and facilities. It is one of the agricultural production sectors.

[0003] In the process of aquaculture, in order to save water resources, it is often necessary to recycle and reuse the aquaculture water, thereby playing the role of water resource recycling and reducing aquaculture costs. However, the aquaculture water contains a lot of dirt and impurities, so the recycled aquaculture water needs to be filtered.

[0004] To address the aforementioned issues, we propose a drum-type microfiltration machine. Utility Model Content

[0019] The technical solution in this application embodiment is to solve the problems of the background technology mentioned above. The general idea is as follows: During use, the filter drum 2 can be rotated by the motor. At the same time, with the setting of the water jet pipe 11 and the dirt collection tank 9, the dirt in the filter drum 2 can be flushed and cleaned, thereby effectively avoiding the filter drum 2 from being blocked due to excessive dirt, and thus enhancing the efficiency and stability of the filter drum 2 in filtering sewage.

[0020] Example: Refer to Figures 1-4 As shown, a drum-type microfiltration machine of this embodiment includes a mounting bracket 1, a filter drum 2 is movably mounted on the inner center of the mounting bracket 1, a front cover plate 3 is provided on the front end face of the filter drum 2, and a water inlet 4 is provided in the center of the front cover plate 3, through which sewage can be fed into the filter drum 2 for filtration.

[0021] The back of the filter roller 2 is provided with a rear cover plate 5, and a drive assembly is provided in the middle of the rear cover plate 5. The drive assembly includes a rotating gear 6, which is fixedly installed in the middle of the rear cover plate 5 and is movably connected to the mounting bracket 1. The rotating gear 6 is connected to a drive gear 7 via a chain drive. The drive gear 7 is installed on the upper end of the mounting bracket 1 and is driven by a motor. The drive gear 7 can be rotated by the motor, and then the rotating gear 6 and the filter roller 2 can be rotated synchronously under the transmission of the chain.

[0022] The filter roller 2 has a dirt collection tank 9 at the upper end of its inner cavity, and a water jet pipe 11 at the upper end of the dirt collection tank 9. The water jet pipe 11 is located on the upper side of the outer periphery of the filter roller 2, and multiple sets of nozzles 12 are installed at the bottom of the water jet pipe 11.

[0023] In some examples, the front cover plate 3 is fixedly installed at the front end of the mounting bracket 1, and the front end of the filter roller 2 is in sealed contact with the front cover plate 3. The front cover plate 3 mainly serves to block and prevent the water entering the filter roller 2 from flowing back, and prevents the sewage from flowing back after entering the filter roller 2. At the same time, a sealing module is added to form a sealing effect with the inner wall of the front end of the filter roller 2, preventing unfiltered dirty water from entering the filtered water body through gaps and polluting the water body.

[0024] In some examples, the top of the mounting bracket 1 is provided with a top cover 8, which is located at the top of the filter roller 2. The top cover 8 mainly serves a protective function to prevent the fine water mist generated by the spray nozzle 12 spraying water to wash the filter screen of the filter roller 2 from drifting outward.

[0025] In some examples, a drain outlet 10 is provided at the bottom left end of the sludge collection tank 9 for the purpose of draining sludge.

[0026] In some examples, the left end of the filter roller 2 is movably connected to the mounting bracket 1 via multiple sets of rollers 13. The multiple sets of rollers 13 mainly provide stable support for the left end of the filter roller 2, enhancing the stability of the filter roller 2 when it rotates.

[0027] The working principle of this utility model is as follows:

[0028] During use, external water is first introduced into the filter drum 2 through the inlet 4. Then, the motor drives the drive gear 7 to rotate, and the chain drives the rotating gear 6 to rotate, thereby driving the filter drum 2 to rotate and filter the water. During the filtration process, a water pump draws clean water and delivers it to the water jet pipe 11. Finally, the water is sprayed out through the nozzle 12 to wash the filter screen on the surface of the filter drum 2, so that the dirt falls into the collection tank 9 and is finally discharged through the outlet 10.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
