Trickle filtration system for aquarium tanks and water level control method thereof

Abstract

The invention discloses a trickle filtration system for aquarium tanks. The key points of the technical scheme are as follows: the trickle filtration system includes a bottom tank placed under a fishtank; an outlet pipe and an inlet pipe are arranged at the bottom of the fish tank; a trickle filtration device and a submersible pump are arranged in the bottom tank; a normally closed electromagnetic valve is arranged on the output pipe; and a position sensor and a controller are arranged in the bottom tank. The water in the fish tank flows into the bottom tank through the outlet pipe. After filtering, the water is pumped back into the fish tank for reuse via the inlet pipe. When the position sensor detects that the water level rises to two thirds of the highest water level in the bottom tank, the outlet pipe is closed by the normally closed electromagnetic valve, the water in the bottom tank is only pumped into the fish tank by the submersible pump, and the water in the fish tank does not flow into the bottom tank anymore. When the water level in the bottom tank drops to one third, the outlet pipe is opened by the normally closed electromagnetic valve, and the water in the bottom tank rises slowly. Thus, the water levels in the fish tank and in the bottom tank are in a state of dynamic cyclic equilibrium, the problem that the water in the fish tank or in the bottom tank is too much and overflows is avoided, and the system can be unattended.

Description

【Technical field】 [0001] The invention relates to a drip filter system of an aquarium and a method for controlling the water level thereof. 【Background technique】 [0002] There are at least the following problems in the existing aquarium drip filter system: [0003] 1. Most of the trickle filter systems are installed on the fish tank, which is not safe, there is a hidden danger of easy falling, it is not easy to replace the filter material, and the volume of the fish tank is large, people can see the trickle filter system through the fish tank, You can also see the sewage and dirt therein, which reduces the ornamental value of the aquarium. [0004] 2, the water in the fish tank is difficult to keep in a dynamic equilibrium state for a long time, the water in the fish tank overflows easily, and after the water overflows, the water pump will continue to work under the condition of water shortage, causing damage to the water pump. [0005] The present invention is made base...
