AI Technical Summary

Technical Problem

Material accumulation at the sealing curtain of existing air-film structures is difficult to clean, and the cleaning process can easily damage the sealing curtain, affecting airtightness and reducing operational safety.

Method used

A sealed soft curtain material discharge system is designed. By setting an opening in the recess of the sealed soft curtain and connecting it with a discharge pipe, the accumulated material is automatically guided to the bottom of the air-film structure using the discharge pipe. Combined with limiting components and openable/closeable valves, automatic material discharge is achieved, ensuring airtightness and structural stability.

Benefits of technology

It enables automatic cleaning of the sealed soft curtain, improves airtightness and structural stability, enhances operational safety, and avoids the time-consuming, labor-intensive, and potential damage risks of manual cleaning.

Abstract

This utility model provides a sealed flexible curtain discharge system, relating to the field of air-supported membrane structure technology. The sealed flexible curtain discharge system is applied to air-supported membrane structures that transport materials via a conveying corridor, and includes a sealed flexible curtain and a discharge pipe. The sealed flexible curtain connects the air-supported membrane structure and the conveying corridor to achieve a seal, and has an opening. One end of the discharge pipe is located at the opening and is connected to the sealed flexible curtain via a connecting component. The connecting component improves the airtightness of the sealed flexible curtain after the opening. When material accumulates in the recess of the sealed flexible curtain, the material automatically slides from the opening to the discharge pipe, and then falls to the bottom of the air-supported membrane structure. An openable / closable valve at the end of the discharge pipe enables automatic material discharge. The discharge pipe is connected to the sealed flexible curtain via a connector, resulting in high discharge efficiency.
