This utility model relates to a fish tank water filtration system, belonging to the category of ornamental fish breeding filtration facilities. The fish tank water filtration system includes a fish tank, a water pump, pipes, and a filter cartridge. A main water intake pipe connects to the inside of the fish tank and is divided into a main filtration pipe and a main flushing pipe via a T-junction. The main filtration pipe and the main flushing pipe are each connected to a T-junction, and the second ports of the two T-junctions are connected via a power pipe, which houses a bidirectional water pump. The third port of the T-junction connected to the main filtration pipe connects to a branch filtration pipe, which has multiple branch tees connected in series. The third port of the T-junction connected to the main flushing pipe connects to a branch flushing pipe, which has multiple branch flushing tees connected in series. A filter cartridge is connected between the branch tees and the branch flushing tees, and filter media is placed inside the filter cartridge. A drain valve is installed at the end of the branch filtration pipe, connecting to external drainage. The end of the branch flushing pipe connects to the inside of the fish tank. This filtration system is placed outside the fish tank and can filter the water inside, maintaining water cleanliness. This device uses a bidirectional motor to achieve both filtration and backwashing, increasing the lifespan of the filter media and avoiding frequent replacements.

This utility model relates to the field of water tank cleaning. Its purpose is to provide a backwashing device for a water intake pump room, comprising several inlet tanks, several suction tanks, and a backwashing mechanism. The suction tanks are connected to their corresponding inlet tanks. A water inlet pipe is installed at the front of each inlet tank, and a quick-opening valve is installed at the rear end of the water inlet pipe. A water pump is installed at the rear of each suction tank, and a water supply network connects the pumps. The backwashing mechanism includes an electric branch valve, an electric main valve, and a main flushing pipe. Several flushing branch pipes extend from the main flushing pipe. A connecting pipe connects to each flushing branch pipe. The electric branch valve is installed between the connecting pipe and the flushing branch pipe. Water flows through the connecting pipe to flush the bottom of the inlet or suction tank, thereby agitating the sediment at the bottom of the inlet or suction tank. This utility model agitates the mud and sand at the bottom of the inlet and suction tanks, discharges the mixed muddy water, and simultaneously backwashes the water inlet pipe.

The utility model provides a kind of for cleaning papermaking multistage filtering water circulating device, belong to clean papermaking technical field, including water circulating mechanism, including water storage bucket, first communicating pipe connected in water storage bucket inside, multistage filtering cylinder for carrying out multistage filtration to water, second connecting pipe connected in multistage filtering cylinder water outlet, for circulating use to water circulation pump;Cleaning mechanism, including for backwashing component for backwashing multistage filtering cylinder, and for the energy recovery component of the flow of backwashing water can be collected.The utility model is matched between backwashing component and energy recovery component, realizes the backwashing and kinetic energy recovery of multistage filtering cylinder, solves the problem that traditional water circulating device lacks backwashing function and needs to frequently dismount cleaning multistage filtering cylinder, to improve cleaning efficiency further, and recycling kinetic energy in backwashing process, to enhance overall energy utilization.
