Description

Technical Field

[0001] The utility model relates to the technical field of sintering equipment, in particular to a sintering safety production steam heating anti-caking device. Background Art

[0002] Sintering machine is a kind of equipment used to sinter ore and other raw materials. Sintering is a metallurgical process that forms granular agglomerates of fine powdered ore and fly ash through a high-temperature heating and cooling process. Sintering machine is the key equipment used to achieve this process.

[0003] In order to avoid internal agglomeration during use, the sintering machine will be connected to a steam spray device, which will spray hot steam into the sintering machine to provide additional heat and air flow, thereby effectively preventing the raw ore from agglomerating during the sintering process.

[0004] The steam spray device currently in use will produce scale inside after long-term use. The scale requires the staff to disassemble the device for cleaning or washing, which is troublesome and laborious. In addition, when using acidic liquid to remove the scale, the hot gas generated by heating will enter the sintering machine, causing corrosion and other damage to the sintering machine.

After transporting an appropriate amount, the transport is stopped, and the switch of the heating rod is turned on. The heating rod is energized to start heating the water in the first cavity. Steam is generated after the water is heated, and the steam enters the interior of the accretion hood, and is transmitted to the interior of the third pipe through the aggregation of the accretion hood. The third pipe transmits the steam to the interior of the reversing valve, and the reversing valve switches the steam and transmits it to the interior of the fourth pipe. The steam entering the fourth pipe is transmitted to the interior of the fan, and finally the fan transmits the steam to the interior of the sintering machine through the fifth pipe, and the steam is sprayed into the sintering machine to prevent agglomeration therein.
