Abstract

The invention discloses a tunnel kiln with an automatic temperature control system. The tunnel kiln with the automatic temperature control system comprises a kiln body extending horizontally and a kiln car driving in the kiln body. A working channel comprises an entrance section, a preheating section, a sintering section, a holding section and a cooling section in sequence in the extending direction. The sintering section is provided with a first hot air supply device for controlling the temperature in the working channel. The holding section is provided with a second hot air supply device for controlling the temperature in the working channel. The preheating section and the sintering section are provided with a barometric sensor used for sensing the barometric pressure in the working channel and a temperature sensor used for sensing the temperature in the working channel. The temperature sensor and the barometric sensor are connected with a control system, and the control system is connected with a hot air machine. According to the tunnel kiln with the automatic temperature control system, the temperature sensor and the barometric sensor are connected with the control system, and the first hot air supply device and the second hot air supply device are arranged, so that the temperature control and pressure control in the kiln can be achieved, the labor cost is saved, and the scientific management degree is improved.

Description

technical field [0001] The invention relates to a tunnel kiln with an automatic temperature control system. Background technique [0002] Tunnel kiln is generally a long linear tunnel with fixed walls and vaults on both sides and top, and kiln cars run on tracks laid at the bottom. The combustion equipment is installed on both sides of the middle part of the tunnel kiln, which constitutes a fixed high-temperature zone - the firing zone. The high-temperature flue gas generated by combustion flows along the tunnel to the kiln head under the action of the chimney at the front end of the tunnel kiln or the induced draft fan. At the same time, the products entering the kiln are gradually preheated, and this section constitutes the preheating zone of the tunnel kiln. The cold air blows into the kiln tail of the tunnel kiln to cool the products in the last section of the tunnel kiln. After the cold air blows in flows through the products and is heated, it is drawn out and sent to ...
