DETAILED DESCRIPTION

[0027] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments of the present application will be described clearly and completely below with reference to the drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments.

[0028] As Figures 1-6As shown, this embodiment proposes a rapid firing tunnel kiln, including a main kiln 1. Symmetrically distributed side plates 22 are fixedly connected to the outer wall of the main kiln 1. Symmetrically distributed guide grooves 23 are formed on the outer wall of the side plates 22. A dummy kiln 2 is fixedly connected to the end of the side plates 22 away from the main kiln 1. Symmetrically distributed guide rails 4 are fixedly connected to the inner walls of both the main kiln 1 and the dummy kiln 2. Uniformly distributed burners 5 are fixedly connected to the outer wall of the main kiln 1. Symmetrically distributed support bases 3 are fixedly connected to the outer walls of both the main kiln 1 and the dummy kiln 2. To improve the firing effect, burners 5 are added above the firing zone of the main kiln 1. Natural gas is added through the upper burners 5 to increase the firing temperature above the main kiln 1, ensuring thorough firing of the ceramic jars. The embodiment also includes:

[0029] The waste heat recovery and preheating component includes a positioning plate 19 fixedly connected to the top wall of the dummy kiln 2. A fan 20 is fixedly connected to the top wall of the positioning plate 19. A waste heat pipe A7 is fixedly connected to the air inlet of the fan 20, and a waste heat pipe B8 is fixedly connected to the air outlet of the fan 20. An installation pipe 6 is fixedly connected to the outer wall of both the waste heat pipe A7 and the waste heat pipe B8. The main kiln 1 generates waste heat during operation, while the dummy kiln 2 itself does not generate heat. The waste heat recovery and preheating component recovers and utilizes the waste heat of the main kiln 1. The fan 20 draws in the waste heat gas generated by the main kiln 1 through the waste heat pipe A7, and then sends the waste heat gas into the dummy kiln 2 through the waste heat pipe B8. The waste heat pipes A7 and B8 are connected to the main kiln 1 and the dummy kiln 2 through the installation pipe 6 to ensure the transmission of waste heat gas.

[0030] The bottom preheating component is located on the inner wall of the fake kiln 2;

The outer wall of the heat-conducting frame 10 is provided with uniformly distributed heat inlet holes 21. The heat-conducting frame 10, the heat-resistant sealing plates 9 and the heat inlet holes 21 in the bottom preheating component work together. The waste heat gas enters the heat-conducting frame 10 through the heat inlet holes 21 to preheat the ceramic jar base located in the dummy kiln 2. Because the ceramic jar base is the thickest and requires the highest firing time and temperature, preheating it in the dummy kiln 2 can achieve a better effect.

The kiln car 14 rotates on the guide rail 4 through the wheels 11, the cushion blocks 18 are used to support the ceramic pots, and the burning holes 17 are convenient for hot air to heat the bottom of the ceramic pots.

[0035] As shown in Figure 1 As a preferred embodiment, on the basis of the above-mentioned mode, further, the main kiln 1 and the dummy kiln 2 are fixedly connected with the installation pipe 6, and the installation pipe 6 is used to connect the waste heat pipe A7 or the waste heat pipe B8.
