Integrated two-layer reverse energy-saving tunnel kiln

Abstract

The invention provides an integrated two-layer reverse energy-saving tunnel kiln, comprising a kiln body, transmission rolls and electric furnace wires, wherein the transmission rolls and the electric furnace wires are arranged in the kiln body. The integrated two-layer reverse energy-saving tunnel kiln is characterized in that the electric furnace wires are uniformly arranged in a mode of being close to the top surface and the bottom surface of the kiln body; a horizontal clapboard is additionally arranged to divide the space in the kiln body into an upper layer and a lower layer horizontally; the transmission rolls are respectively arranged along the proceeding direction in a mode of being close to the bottom of each layer; and the rotating directions of the two layers of the transmission rolls are reverse. The integrated two-layer reverse energy-saving tunnel kiln is characterized in that single-layer transmission is changed into two-layer transmission, the transmission directions of the two layers are reverse, the two layers are separated by the clapboard, so the annealing heat of the upper-layer furnace and the annealing heat of the lower-layer furnace are respectively used as preheating sources for the upper-layer furnace and the lower-layer furnace, and materials are inout and output from the two ends of the tunnel kiln respectively. Therefore, integrated two-layer reverse energy-saving tunnel kiln saves energy, improves efficiency, saves labor and materials as well as space, and has excellent working performance.

Description

technical field [0001] The invention provides an integrated double-layer reverse energy-saving tunnel kiln, which belongs to the technical field of kilns. Background technique [0002] Tunnel kilns traditionally used for ceramics, glass products and hot bending of glass plates have been basically replaced by electric heating. Generally, it is a single-layer transmission, which is divided into three sections: preheating, firing, and annealing according to the heating process requirements. The disadvantages are: 1. High energy consumption: the preheating section needs a heating source, which accounts for about 20% of the total energy consumption; 2. Low efficiency: the heat dissipation in the annealing section is slow, and the transmission speed cannot be increased; 3. Large number of personnel: two operators are required at the kiln head and kiln tail, and at the same time, a special person is required to pull the mold or pallet from the kiln tail back to the kiln head for re...
