Hot melting hopper

Abstract

The invention discloses a hot melting hopper comprising a hopper body. A hot melting cavity, a buffering cavity and a feeding cavity are sequentially arranged in the hopper body from bottom to top. Acommunicating portion used for gas passing is arranged between the hot melting cavity and the buffering cavity. The hot melting cavity is provided with a discharging opening. The discharging opening is provided with a first electronic control valve used for controlling the discharging opening to be opened and closed. A second electronic control valve used for controlling materials to flow or not flow between the hot melting cavity and the buffering cavity is arranged between the hot melting cavity and the buffering cavity. A third electronic control valve used for controlling materials to flowor not flow between the buffering cavity and the feeding cavity is arranged between the buffering cavity and the feeding cavity. The side wall of the hopper body is provided with heating devices located around the hot melting cavity. The hot melting hopper has the advantages that continuous hot melting can be achieved, the hot melting speed is rapid, and the energy utilization rate is high.

Description

Technical field [0001] The invention relates to a hopper, more specifically, to a hot melt hopper. Background technique [0002] Hot melt hopper is a common equipment for heating and melting solid materials into liquid materials, and it is widely used in industrial production. The traditional hot melt hopper only uses a separate hot melt cavity, and the process of heating and melting solid materials is: conveying the solid materials into the hot melt cavity; heating the hot melt cavity; wait until the solid materials are completely melted into liquid materials After that, the heating is stopped; the liquid material is discharged from the discharge port; the solid material is transported into the hot melting cavity again, and the heating and melting operation is cyclically performed. The problem in the traditional process of heating and melting solid materials is that the adding of solid materials and the discharging of liquid materials before and after heating and melting need t...

AI Technical Summary

Problems solved by technology

The problem existing in the traditional process of heating and melting solid materials is: the addition of solid materials and the discharge of liquid materials before and after heating and melting must be carried out in the hot-melt chamber, so the materials cannot be fed in and out at the same time, and the hot-melt process is slow; the solid materials are uniform Heating starts from being transported into the hot-melt cavity, the speed of hot-melt is slow and the excess heat in the hot-melt cannot be used
