Problems solved by technology

Neither can reliably seal the gap between the sides of the trolley
When the furnace is under negative pressure, cold air will leak into the furnace, which will increase the fuel consumption of the furnace due to unreliable sealing

Embodiment Construction

[0014] The present invention proposes a trolley furnace that adopts a water sealing method to seal the gap between the furnace body and the trolley. The structure of the trolley furnace includes a furnace body, a trolley, a furnace door, a furnace body sealing knife, and a trolley sealing knife. The sealing device is arranged between the two sealing knives. The water sealing method adopted in the present invention is to set a water sealing groove, that is, a water groove, at the gap between the two sealing knives, and configure a transmission mechanism to move the sealing water groove up and down—when the furnace door is lowered, the sealing water groove rises to make the sealing knife Immersed in water, when the furnace door is lifted, the sealed water tank will fall, and the trolley can enter and exit freely.

[0015] Those skilled in the art can design various forms of transmission mechanisms according to the principles and requirements of the present invention. Figure 1-...

Abstract

The invention discloses a water sealing method of a bogie hearth furnace, which aims to solve the problem of air leakage existing in the sealing mode of gaps of a bogie and a furnace body of the current bogie hearth furnace. In the water sealing method of the bogie hearth furnace, a sealing water tank is arranged at the gaps of two sides of the furnace body and the bogie, and the sealing water tank is provided with a transmission mechanism for enabling the sealing water tank to move up and down. In the invention, sand sealing and fiber sealing are replaced by water sealing for the bogie hearth furnace, thereby ensuring that the gaps at two sides of the bogie are reliably sealed, improving the heating quality, saving the energy sources and prolonging the service life of equipment.

Description

technical field [0001] The invention belongs to the field of trolley furnaces in industrial furnaces, and in particular relates to a sealing method between a trolley furnace body and a trolley. Background technique [0002] The trolley furnace is a kind of industrial furnace. When working, the trolley loads workpieces outside the furnace, and then the trolley drives the workpieces into the furnace together. After the heating process is completed in the furnace, the trolley carries the workpiece out of the furnace. There must be a certain gap between the two sides of the moving trolley and the fixed furnace body. When performing the heating process, the furnace door falls to close the furnace mouth where the trolley enters and exits, and the gap on both sides of the trolley is also closed. The sealing of the furnace is related to the heating quality and fuel consumption. The gap on both sides of the trolley that is commonly used now, some use sand seals to seal the gap, i...
