Furnace hearth cooling and warning device

Abstract

The invention discloses a furnace hearth cooling and warning device. The tops of the two sides of an outlet of a furnace hearth are provided with temperature thermocouples. The two opposite sides of the outer portion of the furnace hearth are provided with a first lifting frame and a second lifting frame. A sound generator is arranged on the first lifting frame. The part, opposite to the sound generator, of the second lifting frame is provided with a receiver. The receiver is connected with a signal processor. The signal processor is connected with a trigger. The trigger is connected with thesound generator. The sound generator is connected with an air source. The receiver communicates with an instrument air source. The temperature thermocouples and the signal processor are connected witha data processor. The data processor is connected with a displayer. The data processor is connected with a warning device through a sound control device. The furnace hearth cooling and warning devicecan monitor the temperature in the furnace hearth. The service life of a furnace can be prolonged. The consumption cost is reduced. Expenses are cut down. Overburning of a furnace body is avoided. The furnace hearth cooling and warning device can monitor the whole furnace hearth to avoid the omission phenomenon and give a warning in time.

Description

technical field [0001] The invention relates to the technical field of furnace temperature alarm, in particular to a furnace cooling alarm device. Background technique [0002] The temperature measurement and mapping of the furnace has always been a concern of people. However, the function of the furnace is to ensure that the fuel is burned as much as possible. However, if the temperature of the flue gas at the outlet of the furnace cools down to the temperature that the convective heating surface is not allowed for safe work, the furnace will explode. Dangerous accidents occur. In addition, the furnace is turned off during operation, and the fuel supply is not interrupted in time. Sudden spontaneous combustion at high temperatures will also cause explosions, causing major accidents. Contents of the invention [0003] In order to make up for the above deficiencies, the present invention provides a furnace cooling alarm device to solve the above-mentioned problems in the ba...
