AI Technical Summary

Technical Problem

Traditional farmland drainage ditch purification tank devices have a split structure, occupy a large area, have high maintenance costs, and the filter layer is prone to clogging, making them difficult to apply in farmland where arable land is scarce.

Method used

The sunken integrated purification tank, which adopts modular filter components and quick-release maintenance structure, combines a precast concrete box, stainless steel grating, hydraulic cylinder and filter membrane. It achieves synchronous operation through PID control algorithm, which improves processing efficiency and reduces maintenance costs.

Benefits of technology

It achieves efficient purification of farmland drainage within a limited space, reduces maintenance frequency and cost, and improves the practicality of the purification tank.

Abstract

This utility model provides a sunken integrated purification tank device for farmland drainage ditches, including a precast concrete box. A stainless steel grating is movably embedded in the upper left side of the precast concrete box. Bending plates are welded to the upper end of the stainless steel grating, and a pre-filter box is welded to the lower end of the stainless steel grating. Multiple first hydraulic cylinders, multiple second hydraulic cylinders, and multiple third hydraulic cylinders are respectively installed on the upper end of the precast concrete box. A first lifting cover plate is slidably embedded in the middle of the upper end of the precast concrete box. First fins are welded to the upper four sides of the first lifting cover plate, and a biological treatment filter box is welded to the lower end of the first lifting cover plate. This design solves the problems of low treatment efficiency, large footprint, and easy clogging of mechanical structures in the original farmland purification tank. This utility model uses a modular filter component and a sunken integrated purification tank with a quick-disassembly and maintenance structure to improve treatment efficiency and reduce maintenance costs.
