Technical Field

[0001] The utility model belongs to the technical field of aquaculture tail water treatment, and in particular relates to a filtering device for aquaculture tail water treatment. Background Art

[0002] Aquaculture tailwater refers to polluted water caused by leftover bait and feces during aquaculture. If the tailwater is not treated in a timely and effective manner, it will lead to the deterioration of the aquaculture water environment, which may cause outbreaks of diseases or even large-scale deaths of fish, shrimps and crabs, thereby affecting the quality and output of aquaculture products. In summary, the problems existing in the prior art are: a sand filter is a device that uses filter materials such as quartz sand, activated carbon, anthracite, manganese sand, etc. to remove various suspended matter, microorganisms, and other fine particles in the water. It can be applied to the treatment of aquaculture tailwater. When the filter sand and gravel in the sand filter absorb too many impurities, the backwater function of the sand filter can be activated to clean the filter sand and gravel. The filter sand and gravel are in a stationary state during cleaning, and the gaps between the filter sand and gravel are small. Impurities cannot be completely removed by water flushing alone. This method of cleaning the filter sand and gravel is inefficient, but the sand filter used in the existing aquaculture tailwater treatment does not have a component for better cleaning the filter sand and gravel.

The surface of the first toothed disc 702 is meshed with the surface of the second toothed disc 704.

[0024] The above scheme is adopted: by setting the stirring device 7, the setting of the stirring device 7 can make the filtered sand and gravel be turned over when being washed by the washing water, so as to achieve a better washing effect.

The coordinated use of the slider 8 and the slide groove 9 has a limiting effect on the moving position of the moving frame 6.

[0027] refer to Figure 3 The two output ends of the dual-axis motor 4 are fixedly connected to a rotating rod 10, and a rotating hole 11 for use with the rotating rod 10 is opened on the surface of the moving frame 6, and the surface of the rotating rod 10 is movably connected to the inner cavity of the rotating hole 11.

The coordinated use of the inner shell 15 and the outer shell 16 has a limiting effect on the rotation position of the prism 3 .

[0035] The working principle of this utility model:

[0036] During use, when the sand filter 1 used for aquaculture tail water treatment needs to clean the filtering sand and gravel more effectively, the guide cover 14 will first block the tail water flowing into the sand filter 1 to prevent impurities in the tail water from adhering to the surfaces of the third toothed disc 12 and the fourth toothed disc 13. When too many impurities adhere to the filtering sand and gravel in the inner cavity of the sand filter 1, the tail water injection is stopped, and then the backwater function of the sand filter can be started, and the cleaning water will flow out from the water outlet at the bottom of the inner cavity of the sand filter 1. The cleaning water will rinse the impurities adhered to the surface of the filtering sand and gravel, and then the rotating motor 2 can be started. When the rotating motor 2 rotates, it will drive the third toothed disc 12 to rotate along the surface of the fourth toothed disc 13. The fourth rotating disc subjected to the rotational force will drive the prism 3 to rotate. When the prism 3 rotates, it will drive the inner shell 15 to rotate along the inner cavity of the outer shell 16. When the prism 3 rotates When the two stirring frames 5 are rotated, the dual-axis motor 4 is started, and the dual-axis motor 4 drives the two rotating rods 10 to rotate along the inner cavity of the rotating hole 11. The rotating hole 11 is squeezed by the rotating rod 10 and drives the moving frame 6 to move along the inner cavity of the stirring frame 5. When the moving frame 6 moves, it drives the slider 8 to move along the inner cavity of the slide groove 9. Then the rotary motor 701 can be started. When the rotary motor 701 rotates, it drives the first toothed disc 702 to rotate. When the first toothed disc 702 rotates, it drives the three second toothed discs 704 to rotate at the same time. When the second toothed disc 704 rotates, it can drive the three stirring rods 703 to rotate through the rotating shaft at the same time. The filtered sand and gravel are washed by the cleaning water and flipped by the stirring rod 703 and the stirring frame 5 at the same time. At this time, the sand filter 1 used for aquaculture tail water treatment can achieve better cleaning effect on the filtered sand and gravel.

[0037] In summary: the filtering equipment for treating aquaculture tail water solves the problem that the existing sand filter uses filter materials such as quartz sand, activated carbon, anthracite, manganese sand, etc. to remove various suspended matter, microorganisms, and other fine particles in the water by setting a stirring device 7, a rotating motor 701, a first toothed disc 702, a stirring rod 703 and a stirring frame 5. The sand filter can be applied to the treatment of aquaculture tail water. When the filter sand and gravel in the sand filter absorb too many impurities, the backwater function of the sand filter can be activated to clean the filter sand and gravel. The filter sand and gravel are in a stationary state during cleaning, and the gaps between the filter sand and gravel are small. Impurities cannot be completely removed by flushing with water alone. This method of cleaning the filter sand and gravel is inefficient, but the sand filter used for the existing aquaculture tail water treatment does not have a component for better cleaning the filter sand and gravel.
