A device for collecting and utilizing waste heat of pit furnace

Abstract

The invention relates to the technical field of centrifugal glass wool and discloses a wasteheat collecting and utilizing device of a pit furnace. The wasteheat collecting and utilizing device comprises a collecting chamber, a carrying barrel, a feeding pipe, a conducting branch pipe, a current limiting part, a liquid inlet pipe, a liquid outlet pipe, a communicating pipe, a discharge chamber, a fixed barrel, a fit ring, a fixed block, a clamping connection part, an insertion rod, a supporting spring, a clamping connection outer ring, a pull ring, a connecting barrel, a clamping part, a clamping block and an extrusion head. According to the wasteheat collecting and utilizing device of the pit furnace provided by the invention, a high-temperature raw material in the carrying barrel is guided through the arranged feeding pipe to the collecting chamber. When a cooling liquid absorbs wasteheat in the feeding pipe, the cooling liquid is discharged from the liquid outlet pipe through the current limiting part on the left side. The cooling liquid is in tight contact with a fixed outer ring through an arranged auxiliary spring, so that a sealing plate only can be in a single direction rotating state, so that the cooling liquid absorbing wasteheat is discharged immediately, and backflow is avoided. The wasteheat collecting efficiency is guaranteed, the heat utilization ratio is promoted, and the production cost is lowered.

Description

Technical field [0001] The present invention relates to the field of centrifugal glass wool, and is specifically a residual heat collection and utilization device of a changer. Background technique [0002] Centrifugal glass wool is a filamentous material made of fibrosis in a molten state of glass, and then heat-curing deep processing, and can be made into a series of uses, centrifugal glass wool. Internal fibers are fluffy, there is a large amount of slightly pore, is a typical porous sound absorbing material, with good sound absorbing properties, centrifugal glass wool can be made into a wall panel, ceiling and spatial sound absorbing body, etc., can absorb a large amount of room Sound energy, reduce reverberation time, reduce indoor noise.

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a waste heat collection and utilization device for kiln furnaces, which has the advantages of effectively recovering waste heat, etc., and solves the problem that in the preparation process of the existing device, more heat will be attached to the raw materials after preheating. The waste heat generated in the preparation process cannot be exported in time, and it is not effectively used, which increases the production cost and does not have environmental protection benefits
