Hot air circulating pipeline flow guiding and shunting device

By introducing a connecting cylinder and connecting ball structure into the hot air circulation duct, gas backflow is prevented, ensuring unidirectional flow of hot air. This solves the problem of backflow at the branch interface of the splitter, achieves stability of air volume and air pressure, and improves the convenience of maintenance.

AI Technical Summary

Technical Problem

The branch interfaces of existing multi-head splitters are prone to backflow of external air during strong winds or sudden changes in air pressure, affecting the stability of air pressure and the accuracy of air volume distribution in the hot air circulation duct.

Method used

The system employs a connecting cylinder and connecting ball structure. The cooperation between the connecting ball and the connecting cylinder prevents gas backflow, and the design of the rubber sleeve and slider track ensures unidirectional flow of hot air. At the same time, the threaded sleeve and protruding plate facilitate quick disassembly and maintenance of the branch interface.

Benefits of technology

It achieves stable unidirectional flow of hot air, maintains the stability of air volume and air pressure, improves maintenance efficiency, and prevents unstable airflow from affecting process results.

Abstract

This utility model discloses a hot air circulation pipeline diversion and distribution device, relating to the field of pipeline diversion technology. It includes a diversion box with an air inlet on its bottom wall and branch interfaces evenly inserted on its top. Each branch interface has a connecting cylinder fixedly connected to its inner wall, and a crossbar fixedly connected to its inner wall. By incorporating connecting cylinders and connecting balls, this utility model prevents gas backflow during use, ensuring unidirectional hot air flow in the designed direction. This maintains stable airflow and pressure in each branch pipeline, preventing process effects caused by unstable airflow. The device also features threaded sleeves and protruding plates, allowing for quick and easy disassembly of damaged branch interfaces during maintenance. This significantly improves the efficiency of maintenance.
