AI Technical Summary

Technical Problem

The existing filter press has a fixed feeding device, which causes cow manure residue to pile up on the filter belt, resulting in uneven stress on the filter belt and uneven material distribution, thus affecting the dewatering efficiency.

Method used

A feeding assembly including a screw feeder and an electric slide rail was designed. The screw feeder rotates and the electric slide rail moves to achieve uniform distribution of manure residue. The material thickness is adjusted by the material sorting plate and the material pushing teeth to ensure uniform distribution.

Benefits of technology

This method achieves uniform distribution of manure residue on the filter belt, improves dewatering efficiency, avoids incomplete dewatering in thick material areas and easy damage in thin material areas, and enhances the corrosion resistance and stability of the filter belt.

Abstract

This utility model discloses a filter press for dewatering cow dung residue, belonging to the field of filter press technology. This filter press for dewatering cow dung residue includes a belt filter press body and a feeding assembly. The feeding assembly is located outside the belt filter press. The belt filter press body is used to dewater the cow dung residue, and the feeding assembly is used to evenly distribute material onto the second filter belt located at the feed inlet of the belt filter press body. The feeding assembly includes a hopper, with a feed cylinder connected to the upper end of the hopper. A screw feeder is slidably installed inside the hopper, and a corrugated hose connects the feed pipe of the screw feeder to the feed cylinder. Electric slide rails are installed on both sides of the screw feeder inside the hopper, and electric sliders are slidably connected to the outside of the two electric slide rails. The outer wall of the electric sliders is fixedly connected to the outer wall of the screw feeder. A discharge trough is opened at the bottom of the hopper, and the discharge pipe of the screw feeder is located in the discharge trough at the end furthest from the screw feeder.
