[0002] The filter press device for sedimentation treatment of aquaculture tail water is a device used for solid-liquid separation. It mainly separates solid particles from liquid in aquaculture tail water through mechanical pressure. For particulate matter such as leftover bait and feces mixed in aquaculture tail water, belt filter press equipment and plate filter press equipment are usually used.

[0003] In the prior art, the filter press device for sedimentation treatment of aquaculture tail water uses a belt filter press with relatively low equipment cost for filter press treatment. When the tail water is arranged in the belt filter press for filter press, a negative pressure adsorption component under the rubber belt is used to pass through the rubber belt and the filter belt for negative pressure adsorption to complete vacuum adsorption separation. However, since the tail water is exposed to the top of the filter belt and the top is relatively open, the negative pressure strength of only removing the water seal on the top of the tail water is weak, resulting in a high humidity in the filter cake after filter press, a certain amount of water, and a general filter press separation effect.
