In some embodiments, a sterilizing lamp 23 is arranged in the purified water bin 5, a heating rod 22 is arranged in the biochemical filter bin 20, and when the water temperature in the biochemical filter bin 20 is lower than a set temperature, the heating rod 22 is started to heat; when the water temperature in the biochemical filter chamber 20 reaches the set temperature, the heating rod 22 stops heating.

The working principle of the improved physical filtering device in the above embodiment under each mode is as follows:

under normal conditions, when the emptying valve 16 is opened, the liquid level in the filter barrel 1 descends, the filter cotton core 4 descends along with the water level due to self gravity, when the water level descends to a certain degree, the lock male 10 in the middle of the filter cotton core 4 is contacted with the lock female 8 in the middle of the impeller 9 (the lock female 8 and the lock male 10 can be exchanged in position) and matched, and therefore the setting of the filter cotton core 4 in the setting space is realized, at the moment, the emptying valve 16 is closed, and the filter barrel 1 is in a state of waiting for circular filtration.

When the circulation mode of the filter cotton core 4 is started, the water pump 11 is in a working state, the water inlet electromagnetic valve 3 is in an open state, the sealing cover at the top of the filter barrel 1 is sealed and covered relative to the filter barrel, negative pressure is generated in the physical filter barrel 1 at the moment, raw water carrying dirt such as fish feces, residual bait and the like in the fish tank flows into the physical filter barrel 1 under the action of suction, the raw water is sprayed on the barrel wall of the physical filter barrel 1 along a certain angle through the water distributor 2, the raw water generates centripetal force to drive the raw water in the filter barrel 1 to rotate, the raw water flows through the barrel wall through the filter plate, the excrement particles in the fish tank, the feed residual bait falls to the inclined guide plate 13 through the holes of the filter plate due to self gravity, and the residual bait and the excrement flow into the. The residual raw water enters the purified water bin 5 after being physically filtered by the filtering cotton core 4, the check valve 18 in the purified water bin 5 is opened under the action of pressure difference, flows into the biochemical filtering bin 20 for biochemical filtering, and returns to the fish tank after working by the circulating water pump 11, so that the large circulating flow of the water body in the fish tank is realized.

When the filtering cotton core 4 is started to realize the self-cleaning mode, the water pump 11 stops working, the check valve 18 of the purified water bin 5 is closed under the action of pressure difference, and the communication between the biochemical filtering bin 20 and the purified water bin 5 is cut off. The water inlet electromagnetic valve 3 is designed through flow, continues to work and supply water, when the water level in the physical filter barrel 1 is designed, the impeller 9 is acted by a transmission mechanism of the motor 7, the impeller 9 can rotate left and right, the filter cotton core 4 located on the impeller 9 is separated from the impeller 9 along the V-shaped track 21 under the action of centrifugal force, flow is generated along with the rotation of the impeller 9, the water rotates along with water flow in a water body, the water flow falls into the filter barrel 1 under the reaction force of the cover plate 19, the filter cotton core 4 is automatically cleaned under the action of the centrifugal force and the vortex, then sewage is discharged through the drain valve 17 and the excrement cleaning valve, after the cleaning is finished, the filter cotton core 4 falls under the action of the self-gravity force, enters the bottom dead center 213 of the V-shaped track 21, and meanwhile, the seat sealing of a seat sealing space is realized.

When the filter cotton dewatering mode is started, the impeller 9 is rotated singly by the motor 7, the filter cotton core 4 located on the impeller 9 reaches the top dead center 215 along the V-shaped track 21 under the action of centrifugal force, so that the filter cotton core 4 is locked, and the filter cotton core 4 is dewatered and dried under the action of centrifugal force, so that the filter cotton dewatering mode is matched with the cleaning more thoroughly. After dewatering, the filter cotton core 4 enters a waiting circulating filtration state.

The excrement and residual bait self-cleaning mode is started, the blow-down valve 17 is opened, residual bait and excrement settled in the settling bin 6 are discharged under the action of pressure difference, the settling bin 6 is emptied, and the filtering pressure of the filtering cotton core 4 is greatly reduced.
