Energy-saving type preheating furnace

Abstract

The invention discloses an energy-saving type preheating furnace. The energy-saving type preheating furnace comprises a shell, a door sheet, a preheating furnace body and a heat supply box. A plurality of preheating cavities are formed in the preheating furnace body. Drawer-type storage boxes are arranged in the preheating cavities. Storage box lugs are arranged on the left end side faces and the right end side faces of storage box bodies separately. Air inlets in the left side walls and the right side walls of the preheating cavities are provided with air stopping valve plates. The rear ends of the air stopping valve plates are connected with corresponding springs, and the upper ends and the lower ends of the air stopping valve plates are embedded into guide grooves in the upper inner walls and the lower inner walls of the air inlets. Valve plate lugs are arranged on the inner side faces of the air stopping valve plates. Due to the facts that the air stopping valve plates are arranged on the side walls of the preheating cavities and the lugs on the drawer-type storage boxes are matched with the lugs on the air stopping valve plates, when the drawer-type storage boxes are inserted into a preheating box body, the air stopping valve plates can be opened so that hot air can be connected in; and when the drawer-type storage boxes are pulled out, the air stopping valve plates can be reset, ventilation is stopped, excessive heating can be avoided, energy consumption is reduced and energy is saved.

Description

technical field [0001] The invention relates to the field of preheating furnaces, in particular to an energy-saving preheating furnace. Background technique [0002] At present, most of the equipment used for component preheating in the major and medium-sized chemical fiber industries are well-type preheating furnaces, box-type pre-heating furnaces, and small horizontal pre-heating furnaces. , high energy consumption and small scope of application, etc., for components with high preheating requirements or large batches and large volumes, the use effect is poor. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide an energy-saving preheating furnace in order to overcome the above problems. [0004] In order to achieve the above purpose, the method adopted in the present invention is: an energy-saving preheating furnace, comprising a shell, a door panel, a preheating furnace body, and a heating box for supplying heat to the preheating furnace...

AI Technical Summary

Problems solved by technology

[0002] At present, most of the equipment used for component preheating in large and medium-sized chemical fiber industries are well-type preheating furnaces, box-type preheating furnaces, and small horizontal preheating furnaces, which generally have uneven temperature, high operating strength, and poor sealing performance. , high energy consumption and small scope of application, etc., the use effect is poor for components with high preheating requirements or large batches and large volumes
