Furthermore, the kiln body is also provided with a plurality of air inlets above the flue gas inlet, and the air inlets are provided with air regulating valves. The temperature of the flue gas is about 180 ℃, and a proper amount of air is added for cooling, so that the temperature is easy to adjust.
Further, the kiln body is in a straight tunnel shape.
Further, kiln car tracks are arranged below the interior of the kiln body, at least one kiln car is arranged, a traction device is arranged at the rear of the kiln body and provided with a traction rope, a traction rope hole is formed in the rear door of the kiln body, and the traction rope penetrates through the traction rope hole to be connected with the kiln car.
Furthermore, the traction rope hole is provided with a pulley.
Furthermore, the temperature measuring device is a temperature sensor.
Further, the induced draft fan is connected with a bag-type dust collector; and carrying out harmless treatment on the flue gas.
Compared with the prior art, the utility model has the advantages that the high temperature flue gas is introduced through the flue gas inlet, the energy consumption is saved, on the other hand, the flue gas generally has high-concentration carbon dioxide, the pre-curing of the aerated concrete cured by the carbon dioxide is more professional and effective, and the pre-curing time is saved; each temperature measuring device monitors the temperature of each section in the kiln body, so that the requirements of aerated concrete with different ingredients and different pre-curing processes can be met, and the pre-curing at different temperatures in different stages can be simultaneously carried out; the kiln body front door and the kiln body back door arranged on the kiln body and the induced draft fan enable the interior of the whole kiln body to be negative pressure, smoke is prevented from leaking, and the working environment of personnel is improved.
The utility model has the advantages that: (1) the traditional steam heating mode for the pre-curing kiln is cancelled, and the waste heat of the flue gas after combustion in the industrial kiln is used for heating the green body, so that the energy is greatly saved, and the resource recycling of waste is realized; (2) the atmosphere in the furnace can be adjusted, particularly for the aerated concrete cured by carbon dioxide, the hardening time of the green body is shortened, the production efficiency is improved, and the emission of the carbon dioxide is reduced; (3) the flue gas flow in the kiln can be controlled by adjusting the opening of the flue gas inlet and outlet valves at different positions, so that the temperature in different sections in the kiln can be independently controlled, different gas concrete ingredients can be added, and various requirements on a pre-curing process can be met; (4) the novel pre-curing kiln is in a straight tunnel shape, can be pulled to enter a plurality of kiln cars at one time, can be pre-cured in different stages simultaneously, can realize continuous production, and improves the production efficiency and the labor environment.
