Description

Technical Field

[0001] This utility model relates to the field of sponge foaming nozzle technology, specifically a sponge continuous foaming nozzle that uses liquid carbon dioxide as a foaming agent. Background Technology

[0002] The foaming process involves mixing various liquids that undergo rapid chemical reactions to produce a solid, soft substance. The shorter the residence time of these mixed liquids within the foaming nozzle cavity, the less likely solid blockages will form, resulting in a more uniform sponge density. The sponge density is controlled based on the raw material formula and control parameters. Besides the foaming agent formula, the cutting gap and smoothness of the nozzle during foam formation are also crucial factors, requiring rapid and precise adjustment of the nozzle's spray gap. At the end of each shift, the remaining foaming agent in the nozzle has already reacted, necessitating nozzle disassembly and cleaning. Otherwise, these residues will form hard blockages within the nozzle cavity, affecting the quality stability of the sponge produced in the next shift. Therefore, the quality of the foaming equipment nozzles determines the quality of the sponge product. The quality of the nozzles is primarily assessed by the precision and ease of nozzle gap adjustment, disassembly, and cleaning.

[0003] Currently, in continuous foaming equipment for sponges using liquid carbon dioxide as a foaming agent, both domestically and internationally, multi-layer filter shower nozzles and gantry nozzles are commonly used. Multi-layer filter shower nozzles are prone to clogging during production, affecting the continuity and stability of production. Gantry nozzles, due to their large size, are difficult to adjust the spray gap each time, and disassembly and cleaning are time-consuming and labor-intensive each shift, causing considerable inconvenience to operation. Therefore, there is a need for a sponge foaming nozzle with a clever structure that facilitates gap adjustment and disassembly for cleaning. Utility Model Content
