Title: Jun Zheng and His Blast Furnace Sealing Invention.

Introduction

Jun Zheng is an inventor based in Chongqing, China. His recorded patent work includes an invention for improving the sealing performance of a blast furnace distributing device. The available information identifies him as a man and lists 1 patent.

Latest Patents

The listed patent is “Blast furnace distributing device with nitrogen sealing structure.” It describes an improved device that uses nitrogen sealing and divides the sealing structure into two functional areas.

Near the lower side of the blast furnace, a labyrinth structure helps limit dust and increases resistance to gas pressure loss inside the furnace, supporting the sealing of an upper floating ring. Near the upper side of the distributing device, intermatching floating rings remain in contact through self-adaptation during operation and become more closely fitted through mutual running-in. This arrangement is intended to provide effective sealing without requiring high-precision manufacturing. Maintaining pressure above the blast furnace pressure helps ensure that the floating rings receive sealing force.

Career Highlights

The available information highlights Zheng’s work on blast furnace equipment, particularly a nitrogen sealing structure designed to improve dust control and sealing performance while avoiding demanding manufacturing tolerances.
