Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, and more specifically to a factory-based aquaculture circulating water filtering device. Background Art

[0002] In a factory-scale batch farming environment, a filtration device is needed to circulate and filter the water to reduce or remove impurities such as algae, suspended matter, particulate matter, etc. in the water, reduce the turbidity of the water, and thus achieve the purpose of purifying the water quality to ensure that the water can be recycled.

[0003] After searching, the existing patent (Announcement No.: CN217895354U) discloses a factory-scale aquaculture circulating water filtration device, which uses a filter screen and an activated carbon net to intercept and filter impurities in the circulating water when in use, and by installing a cleaning brush on the top of the stirring blade, when the stirring blade rotates, it drives the cleaning brush to rotate, so that the cleaning brush can clean the filter screen and the activated carbon net, avoiding the problem of internal blockage caused by long-term filtration of the filter screen and the activated carbon net. However, the inventor found the following problems in the prior art during the implementation of the utility model: the above-mentioned filtering device, during the use of the filter screen, although the cleaning brush is used to clean the surface of the filter screen to maintain the penetration of the filter screen, lacks a structure for collecting and discharging impurities, resulting in the accumulation of impurities at the front end of the filter screen during use, affecting the normal flow of the circulating water, thereby reducing the filtering efficiency of the circulating water.

[0004] In view of this, the utility model proposes a factory farming circulating water filtering device with the function of discharging impurities to solve this problem. Utility Model Content

[0011] Furthermore, the side cross-section of the piston plate is a rectangular structure. When the slag outlet corresponds to the slag collecting chamber, the slag collecting chamber and the discharge port are separated by the piston plate.

The arc-shaped push rod is rotated to drive the impurities into the slag outlet, and the impurities then enter the slag collecting chamber. The hydraulic rod is periodically extended and retracted to drive the piston plate to the right, so that the slag collecting chamber corresponds to the discharge port. Under the action of gravity, the impurities in the slag collecting chamber can fall out from the discharge port, so as to achieve the purpose of collecting and discharging the filtered impurities, and there is no need to shut down the device during the impurity discharge process, so it is easy to use.
