A combined annular energy-saving kiln

Abstract

The invention discloses a combined annular energy-saving kiln which comprises a kiln body supporting frame (1). The combined annular energy-saving kiln is characterized in that an annular rail (3) is coaxially installed in the middle portion of the upper surface of a kiln body base (2); a plurality of n-shaped fixing frames (4) are perpendicularly fixed to the kiln body base (2) at equal intervals; a preheating section (7), a heating section (8) and a cooling section (9) are sequentially arranged on the kiln body base (2); a plurality of heating and heat insulating kiln wall modules (11) are installed on a side wall frame of the preheating section (7) side by side; and cooling and recycling kiln wall modules (12) are installed on a side wall frame of the cooling section (9) side by side. The combined annular energy-saving kiln is reasonable in structure, overhauling of the kiln and part replacing are very convenient, the area and the volume of replaced parts are relatively small during repairing, the repairing and maintaining cost is relatively low, the consumed time is relatively short, the production efficiency is improved, the heat insulation performance is improved, in addition, heat can be recycled, cyclic utilization of heat energy is achieved, and the energy-saving effect is obvious.

Description

technical field [0001] The invention relates to an energy-saving kiln, in particular to a combined annular energy-saving kiln, which belongs to the technical field of energy-saving kiln equipment. Background technique [0002] At present, large-scale kilns generally adopt straight-through, segmented or tunnel structures, and generally need to be divided into multiple processing stations or heating treatment sections. The traditional kiln has a single structure, poor thermal insulation performance and heat recovery and utilization, and the energy saving effect is not significant. At the same time, most of the existing kilns have a fixed overall structure, and the kiln needs to be overhauled after a certain period of operation, and it is very inconvenient to overhaul and replace parts. If the thermal insulation layer, furnace lining, inner wall and other parts of the kiln body are damaged, production needs to be stopped for overhaul. The area and volume of the parts to be rep...

Problems solved by technology

[0003] The purpose of the present invention is to solve the existing kilns with single structure, poor thermal insulation performance and thermal energy recycling, and insignificant energy-saving effect. It is relatively large, the maintenance cost is high, the time is long, and the production efficiency needs to be improved. Now we provide a kind of reasonable structure, good heat preservation performance, improved heat recovery and utilization rate, and the maintenance and parts of the kiln. The replacement is very convenient, the area and volume of the parts to be replaced during maintenance are relatively small, the maintenance cost is low, the time spent is short, and the production efficiency has been improved.
