Embodiment Construction

[0026] Attached below figure 1 The present invention is described in further detail with specific embodiment:

[0027] as attached figure 1 As shown, the working principle of the kiln of the present invention is that the kiln body is open at one end and closed at the other end, and the inner chamber of the furnace is provided with folded upper and lower two-layer push plate rails 3, 2 for opposite transmission, and the middle fortification slag baffle 6, working At this time, the push-plate track 3 on the upper layer will place the grid-shaped transparent shelf 5 and the green body 14 to be heated on it to pass through the rapid dehydration section A-B, the oxidation section BB', and the reduction section B'- C is transported to C at the other end of the kiln body; when it reaches C, the green body 14 together with its shelf 5 is transported by the elevator 10 to the entrance C' of the reverse track on the lower floor, and is fired by the reverse push plate track 2 on the low...

Abstract

The invention relates to a novel tunnel-type folded-rail continuous sintering furnace and a sintering method thereof. The novel tunnel-type folded-rail continuous sintering furnace comprises a furnace body, wherein one end of the furnace is open while the other end of the furnace is closed; an upper layer of roll-type or push-plate-type conveying devices (3) and a lower layer of roll-type or push-plate-type conveying devices (2) which are folded and move in opposite directs are arranged in the inner cavity of the furnace; a slag falling-preventing baffle plate (6) and a carrying mechanism (10) capable of doing an up-and-down reciprocating movement are arranged between the two layers; and a heating device (9) and a fuel gas curtain separating nozzle (8) are arranged in the inner cavity of the lower layer of the furnace. By virtue of a super-fast single-sided heating sintering mechanism, and by the adoption of a pair of opposite conveying devices with an extremely high heat exchanging rate and an extremely high afterheat utilizing rate, the temperature difference between the upper layer and the lower layer can remain about 150-300 DEG C at the same section, thus achieving the most economical ceramic continuous sintering state; therefore, the novel tunnel-type folded-rail continuous sintering furnace is a novel continuous sintering furnace with a super-high sintering speed, an extremely high heat exchanging rate and a super-short length.

Description

technical field [0001] The invention relates to an industrial kiln for firing ceramic products, in particular to a novel tunnel-type folding track continuous firing kiln and a firing method thereof. Background technique [0002] At present, roller kilns are often used for firing ceramics in industry. In addition, there are continuous firing kilns such as tunnel kilns and shuttle kilns. Combined with the combination method of the drying room, the waste heat in the cooling part is drawn back to the preheating part to dry the green body to be fired through the heat recovery and ventilation device, which saves energy. However, the existing continuous firing kiln adopts a single-direction conveying and firing method, and the length of the kiln is relatively long. Using this method to dry the green body needs to waste a lot of electric energy. The heat exchange effect is not ideal, and the heat energy utilization rate is low. Therefore, the current ceramic firing kilns have the ...
