Industrial kiln furnace pressure regulating device

By designing an industrial kiln furnace pressure regulating device, the preload of the spring is adjusted by the threaded connection between the rotating column and the pressure plate, and the furnace pressure is automatically regulated. This solves the problem of abnormally high furnace pressure, realizes closed-loop control for stable pressure, and improves the stability of the calcination process.

AI Technical Summary

Technical Problem

The pressure inside the furnace of an industrial kiln rises abnormally due to poor flue gas discharge, affecting the stability of calcination. Existing technology cannot discharge the excessive pressure in a timely manner.

Method used

An industrial kiln furnace pressure regulating device was designed. The furnace pressure is guided to the pressure regulating mechanism through the through pipe and branch pipe. The preload of the clamping spring is adjusted by the threaded engagement between the rotating column and the pressure plate. The furnace pressure control threshold is set. When the pressure exceeds the threshold, the cone plug automatically opens the pressure relief hole to release the excess pressure. After resetting, it is sealed, forming a closed-loop control.

Benefits of technology

It achieves automated regulation of furnace pressure, ensuring stable pressure, avoiding abnormal increases, and improving the stability and safety of the calcination process.

Abstract

This utility model relates to the technical field of auxiliary equipment for industrial kilns, specifically an industrial kiln furnace pressure regulating device. It includes a kiln body, a through pipe connected to the outside of the kiln body, a branch pipe connected to the through pipe, and a pressure regulating mechanism installed on the branch pipe. The pressure regulating mechanism includes a base, a cone plug, a pressure plate, and a rotating column. This industrial kiln furnace pressure regulating device guides the furnace pressure to the pressure regulating mechanism through the through pipe and branch pipe. The preload of the pressure spring can be adjusted by the threaded engagement between the rotating column and the pressure plate, thereby setting the furnace pressure control threshold. When the furnace pressure exceeds the preload setting value of the pressure spring, the pressure pushes the cone plug upwards to open the pressure relief hole and release the excess pressure. After the pressure drops to the set value corresponding to the preload, the cone plug resets and seals under the elastic force of the pressure spring, forming a closed-loop path of automatic overpressure release and reset, thus achieving pressure control.
