Problems solved by technology

However, research has found that when the calcium carbide pot in the tunnel kiln device is cooled to the point where the calcium carbide pot can be grasped, the calcium carbide pot is still in a state of melting and overheating, and some waste heat has not been effectively utilized.

Embodiment Construction

[0022] A stirring device for recovery of waste heat from calcium carbide pots is located in the high-temperature chamber of the tunnel kiln device for recovery of waste heat from calcium carbide pots. There are 10 sets in one set, corresponding to the 10 calcium carbide pots that come out of the kiln once in the tunnel kiln. It includes a stirring head 1, a stirring blade 2, a thermocouple 3, a stirring rod 4, a thermal insulation layer 5, a disc transmission device 6, a horizontal truss 7, a lifting truss 8, a vertical truss 9 and a connecting rod 10. The stirring blade 2 is located directly below the stirring head 1. The heat insulation layer 5 connects the stirring rod 4, the horizontal truss 7 and the connecting rod 10. The horizontal truss 7 can move horizontally in the track of the lifting truss 8, and the connecting rod 10 can be driven relative to the disc. The device 6 makes its own circular motion, and the horizontal truss 7 ensures that the stirring rod 4 moves horiz...

Abstract

The invention provides a stirring device for calcium carbide pan waste heat recovery and an application method of the stirring device. The stirring device for calcium carbide pan waste heat recovery comprises a stirring rod, a stirring head, a stirring blade, a thermoelectric couple, thermal insulating layers, a transmission device and a control device. Through the front-back and up-down sliding and moving motion and horizontal circular motion of the whole stirring device and the feedback of the thermoelectric couple on the temperature of calcium carbide in a calcium carbide pan, the purpose of accelerating the recovery of parts of waste heat of the calcium carbide center is achieved. The stirring device for calcium carbide pan waste heat recovery has the beneficial effects that an integrated casting technology is adopted, the trouble of needing to consider many complex driving problems is omitted, and the strength is improved; hollow ceramic materials are adopted in the whole stirringdevice, the stirring device is lighter, has high temperature resistance and poorer heat-conducting property, and mechanical faults of the transmission device generated by excessive temperature is notprone to occurring; and the shape of the stirring blade is in a sharp leaf shape, the stirring blade is not prone to touching the wall surface of the calcium carbide pan during stirring, heat exchange coefficients are sufficiently improved, meanwhile, the calcium carbide is not prone to bonding and being brought when taken out, and the waste heat recovery efficiency is improved.

Description

technical field [0001] The invention belongs to the field of waste heat recovery of tunnel kilns, and relates to a stirring device for recovery of waste heat from calcium carbide pots in tunnel kilns and an application thereof. Background technique [0002] High-temperature fused calcium carbide (melting temperature up to 2300°C, up to 2600°C) contains a lot of energy. At present, the fused calcium carbide in the calcium carbide factory mainly relies on natural cooling in the calcium carbide pot, which will not only cause production and logistics transportation due to long cooling cycles The problem of long cycle time also causes a great waste of high-temperature waste heat in the calcium carbide pot, and the resulting economic loss. [0003] The applicant previously proposed a tunnel kiln device for recovery of waste heat from calcium carbide pots, which can effectively shorten the cycle of calcium carbide production and logistics transportation, and at the same time effect...
