AI Technical Summary

Technical Problem

During the production of polyethylene cable materials, the granular finished products fall in concentrated strands, resulting in low efficiency of the magnetic frame in adsorbing iron impurities, and there is a risk that iron impurities will flow into the finished product.

Method used

Design a hopper structure comprising a conical diverter screen and a magnetic frame. The conical diverter screen has through holes for dispersing granular finished products, and the magnetic frame adsorbs iron impurities. Combined with a detachable support plate and hopper cover, it facilitates observation and cleaning.

Benefits of technology

It improves the filtration efficiency of iron impurities, prevents iron impurities from falling back into the granular finished product, reduces the risk of finished product contamination, and facilitates equipment maintenance and cleaning.

Abstract

The utility model discloses a hopper capable of improving iron impurity filtering efficiency, which belongs to the field of hoppers and comprises a hopper body with a feeding port and a discharging port. The conical diversion sieve and the magnetic frame are sequentially located in the hopper body in the gravity direction, and a plurality of through holes are formed in the conical diversion sieve; the bearing plate is connected with the hopper body in a drawing mode, the conical flow dividing screen is detachably connected with the bearing plate, and the bearing plate is provided with a channel communicated with the through holes. And the conical shunting screen is conical or pyramid-shaped. The conical flow dividing screen comprises four isosceles triangular plates which are sequentially connected in a closed mode, a plurality of through holes are formed in each isosceles triangular plate, and each isosceles triangular plate is detachably connected with the bearing plate. The utility model has the technical effect that the granular finished products can be conveniently prevented from falling in a concentrated strand shape in the hopper.
