[0004] The existing Chinese patent application with publication number CN116239170A discloses a marine seawater filter, including a treatment box and a reverse osmosis box, a storage box is fixedly installed in the treatment box, a frame is fixedly installed on the top of the reverse osmosis box, a hydraulic push rod is fixedly installed on the frame, an output rod of the hydraulic push rod is fixedly connected to a push-pull rod, the push-pull rod is connected to an infusion mechanism, the infusion mechanism is connected to the reverse osmosis box and the storage box, a filtering mechanism is installed between the storage box and the treatment box, a moving mechanism is installed between the treatment box and the push-pull rod, and the moving mechanism is connected to the filtering mechanism. The output rod of the hydraulic push rod moves up and down, driving the infusion mechanism to transport seawater, the seawater is first filtered by the filtering mechanism and then enters the reverse osmosis box for reverse osmosis, and finally obtains seawater with impurities removed and reduced salt content, which is convenient for cooling and heat exchange of equipment in the ship, and the push-pull rod drives the moving mechanism to move intermittently, so that the filtering mechanism is self-cleaned in the gap of seawater transportation, thereby improving the operation efficiency of the device.

[0005] However, the seawater filter has the following defects when used specifically:

[0006] 1. When the existing seawater filter is in use, although the filter screen inside the seawater filter can be well cleaned to achieve the effect of preventing the seawater filter from being blocked, the effect of preventing the water flow inside the delivery pipe is not high when the seawater filter is used daily, and when the side wall of the seawater filter is protected from backflow inside the delivery pipe, the effect of synchronously adjusting the delivery flow inside the delivery pipe is not high, so that when the seawater filter is used daily, the delivery pipe will have backflow for a long time, reducing the delivery efficiency of the seawater filter;

[0032] 2. The marine seawater filter is provided with an adjusting fan plate. When the water flow rate of the delivery pipe is greater than the side close to the seawater filter during daily use through the delivery pipe, the movement of the sealing block is connected by the rotation of the rotating rod, driving the adjusting fan plate to flip along the outer wall of the fixed block, thereby effectively adjusting the size of the opening on the surface of the fixed block, and playing the role of blocking the block to synchronously adjust the water flow rate inside the delivery pipe through the flipping movement of the adjusting fan plate when the water flow is transmitted through the delivery pipe;
