The filter structure of the existing freshwater aquaculture box requires frequent disassembly of the filter element, which is inconvenient to operate and will affect the continuity of water circulation during the disassembly.
Using a filter separation structure, a rotatable screen roller is used as the main filtering component. Sewage is discharged into the screen roller through the drain pipe, and water drips into the lower storage tank. Particulate pollutants are blocked and collected and removed through the cleaning mechanism of the rotating and negative pressure suction box.
It achieves the effect of cleaning without disassembling the screen roller, ensuring the continuity of filtration and water circulation.

Abstract

Technical Field
[0001] The utility model relates to the field of freshwater aquaculture boxes, and more specifically, to a filtering structure of a freshwater aquaculture box. Background Art
[0002] Freshwater aquaculture is an economic activity that uses freshwater bodies as space, feeds fish or other aquatic animals, and ultimately obtains fish or other aquatic products, thereby achieving certain economic benefits. Freshwater aquaculture provides humans with a large amount of high-quality animal protein and is one of the main sources of high-quality animal protein for humans in the future. It is of great significance to improving the food structure.
[0003] In order to facilitate breeding, it is sometimes necessary to use breeding boxes for breeding. Although this breeding method is easy to manage, it puts forward higher requirements for the filtering and purification structure of the water quality. Most of the existing freshwater breeding box filtration structures use the structure of filter elements to filter the circulating water. Such a structure not only requires frequent removal of the filter element, which is inconvenient to operate, but also requires the corresponding circulation pipeline to be cut off during the removal of the filter element, affecting the continuity of the water circulation. Therefore, we propose a freshwater breeding box filtration structure to solve the above problems. Utility Model Content

A driving motor 309 is fixedly installed on the side wall of the mounting plate 302 near the position of the external gear 303. The driving shaft of the driving motor 309 passes through the other side of the mounting plate 302 and is fixedly installed with the driving gear 304. An electric cylinder 310 is fixedly installed on the side wall of the other mounting plate 302, and the telescopic rod of the electric cylinder 310 passes through the other side of the mounting plate 302, and the end of the telescopic rod of the electric cylinder 310 is fixedly installed between the connecting piece 311 and the guide rod 306.
[0030] The working principle of this filtration separation structure is:
[0031] First, the sewage in the upper breeding box 1 can be directly discharged into the screen drum 301 through the drain pipe 5. At this time, since the height of one end of the screen drum 301 located on the side of the drain pipe 5 is higher than the end of the screen drum 301 located on the side of the collection box 312, the clean water after the sewage is filtered inside the screen drum 301 can directly drip into the water storage tank 2 through the screen drum 301, and the particulate pollutants in the sewage are blocked inside the screen drum 301. Among them, the particulate pollutants with larger particle sizes fall into the collection box 312 as the screen drum 301 rotates, and the smaller particle sizes attached to the mesh inside the screen drum 301 The particulate pollutants rise to the top as the screen drum 301 rotates. The rotation principle of the screen drum 301 here is that the driving shaft of the driving motor 309 drives the driving gear 304 to rotate, and then drives the outer gear 303 and the screen drum 301 to rotate as a whole. Then, the particulate pollutants with smaller particle sizes are scraped and adsorbed into the inside of the vacuum cleaner 308 by the reciprocating scraping of the negative pressure suction box 305, so as to achieve the cleaning effect of the screen drum 301. The reciprocating movement of the negative pressure suction box 305 is achieved by the reciprocating movement of the guide rod 306. The telescopic rod of the electric cylinder 310 is connected to the guide rod 306 through the mounting plate 302 to provide driving force for the reciprocating movement of the guide rod 306.

[0034] The setting of the micro water pump 4 can transport the filtered and collected water inside the lower water storage tank 2 to the upper breeding box 1 through the connection between the connecting pipe 1 and the connecting pipe 2, so as to realize the recycling of water.
