Description

A kind of closed calcium carbide furnace combined central bell

Technical field

The utility model belongs to calcium carbide production equipment field, and in particular to a kind of closed calcium carbide furnace combined central bell.

Background technology

In calcium carbide production, sometimes calcium carbide material spray, turns over calcium carbide, and even electrical phenomena can be caused to center bell equipment, can be right Equipment causes to puncture, leak in burner hearth, such as handles not in time, needs personnel into burner hearth is advanced into, carries out repair welding, it may occur that big Security risk.

Existing center bell is all an entirety, and dismounting is all especially difficult every time.If local defect, or damage, weldering When connecing difficulty, just necessary integral disassembly, assembly, including water-cooled jacket, blanking column, the equipment such as Sealing.

Integral disassembly, assembly, security risk is big, and labor intensity is big, and production repair, replacement is given to bring a great deal of trouble.Integral disassembly, assembly About 25 tons or so of all devices, and furnace surface temperature is high, there are personnel the security risks such as to fall, and also has an impact manufacturing schedule.

Invention content

To solve the above existing problem, the utility model provides a kind of closed calcium carbide furnace combined central bell.

To achieve the goals above, the technical solution that the utility model is taken：

A kind of closed calcium carbide furnace combined central bell, including center bell, which is characterized in that center bell is by three agllutinations Structure and all identical center bell unit (1) of size are put together, and each unit is fastened by bolt (2), junction asbestos (3) Sealing；The center bell unit (1) is equipped with water inlet (4) and water outlet (5).

Further, the water inlet (4) is arranged in pairs with water outlet (5), is located at the edge of center bell unit (1), It is communicated with two layers of water route (6).

Advantageous effect：The utility model uses combined type bell, three equal parts, centre to be connected with again.Connection place is done Sealing, appearance and size does not change after combination；If local damage, need not all it replace, other equipment, directly can be with without dynamic It removes, only replaces part, other two parts water flowing can also be kept, bell is all magnetism-free stainless steel because centered on, will not be local Carbonization, avoids secondary scaling loss equipment.Personnel replace assembly and bring huge benefit, directly shorten for 90% or more time；And it can To save 60% or more equipment funds, while personnel's dismounting is reduced, avoids personnel safety hidden danger.
