Embodiment Construction

[0015] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0016] Please refer to the figure, the present invention provides a technical solution: a foaming tank, including a tank body 1 and an air inlet pipe 2, the air inlet pipe 2 includes a horizontal pipe 21 and a vertical pipe 22, and the horizontal pipe 21 is formed by the tank body 1 The outside horizontally penetrates into the tank body 1, and the vertical pipe 22 vertically penetrates into the tank body 1 from the outside of the tank body 1 and communicates with the horizontal pipe 21 in the tank body 1. There are several holes connected to the tank body on the vertical pipe 22. Corresponding gas outlet 23 inside the body 1. There is an inlet door 11 on the top of the tank body 1 and an outlet door 12 on the bottom. The beads enter the tank body...

Abstract

The invention discloses a foaming tank. The foaming tank comprises a tank body and an air inlet tube, wherein the air inlet tube comprises a transverse tube and a vertical tube, wherein the transverse tube horizontally penetrates into the tank body from the outside of the tank body; the vertical tube vertically penetrates into the tank body from the outside of the tank body and communicates with the transverse tube in the tank body; a piston block capable of sliding vertically is arranged in the vertical tube; space between the piston block and the vertical tube is airtight; the piston block is driven by a screw down mechanism to move vertically; and a plurality of air outlets which correspond to the inside of the tank body are formed in the vertical tube and are positioned below the piston block. The piston block moves downwards in the vertical tube to increase pressure of steam sprayed out from the air outlets, and therefore, the distribution rate of the steam in the foaming tank is increased.

Description

technical field [0001] The invention relates to a foam tank. Background technique [0002] EPP is the abbreviation of expanded polypropylene (Expanded polypropylene), which is the abbreviation of a new type of foam. EPP has light specific gravity, good elasticity, shock resistance and compression resistance, high deformation recovery rate, good absorption performance, oil resistance, acid resistance, alkali resistance, resistance to various chemical solvents, non-absorbent, insulation, heat resistance (-40 ~ 130 ° C), non-toxic Odorless, 100% recyclable with virtually no loss of performance, it is a true environmentally friendly foam. The EPP molding process includes pre-foaming, molding and drying. Pre-expansion is to heat the beads with steam in the foaming tank, and the volume of the beads will expand after heating and softening to reach the required expansion ratio. The foamed EPP beads are molded into EPP products of various shapes in a molding machine. [0003] The...
