Abstract

The utility model relates to a hot air outlet device which effectively solves the problems in the existing hot air outlet of easy deformation, poor sealing, leak out and gas leakage. The utility model has the technical scheme that the device comprises an outlet main body; the interior of the outlet main body is in a cylindrical shape; the inner side of the outlet main body is bricked into a whole by z-shaped refractory bricks and wedge-shaped insulation bricks; a circular pouring material layer is arranged outside the outlet main body, a spraying paint layer is arranged outside a cylindrical part at the outer part of the outlet main body; a semi-annular groove in level with the z-shaped refractory bricks is formed by the pouring material layer outside the upper half part of the outlet main body and a fibrofelt; a filled pouring material layer is arranged at the position that the outer side of the lower half part of the outlet main body is in level with the z-shaped refractory bricks; and the z-shaped refractory bricks are connected with the wedge-shaped insulation bricks in a bricking way. The device has the advantages of novel and unique structure, good seal performance and long service life, saves energy and is environmentally friendly, and the bricks can not drop, therefore, the device has good economic benefit and social benefit.

Description

A kind of hot-blast outlet device

Technical field

The utility model relates to hot-blast stove, particularly relates to a kind of hot-blast outlet device that hot-blast stove is used.

Background technology

Hot-blast outlet is many at present is built into refractory material, because the problem that exists on its structure, specification requirement height when assembling often is difficult to meet the demands, export yielding, sealing effectiveness is poor, and service life is short, particularly in the air-supply of pulsed, the cold and hot variation temperature difference is big, outlet is shunk frequent, and easily causing lays bricks comes off, runout gas leakage is forced to the blowing out maintenance, cause heavy losses to enterprise, now adopt the modular tile outlet with having, but since unreasonable on the structural design, still exist the card envelope not tight, there is the gas leakage runout to take place, influence ordinary production, therefore, the improvement of hot-blast outlet is imperative with innovation.

Summary of the invention

At above-mentioned situation, for overcoming the defective of prior art, the purpose of the utility model just provides a kind of hot-blast outlet device, and it is yielding effectively to solve existing hot-blast outlet, poorly sealed and runout gas leakage problem.

Technical scheme is, the utility model comprises the outlet main body, be cylindric in the outlet main body, outlet main body inboard is built into one by z type refractory brick and wedge type insulating brick, there is the circular cast bed of material outlet main body outside, and external cylindrical portion has by the spraying bed of material, and the first half outside cast bed of material of outlet main body constitutes the semi-circular groove concordant with the z shaped brick with fibrofelt, there is the cast bed of material that tamps in the Lower Half outside of outlet main body with the concordant place of z type refractory brick, the fire-resistant brick company of z type refractory brick and wedge type.

The utility model novel structure, uniqueness, good seal performance is laid bricks and is not held in the palm, and the life-span is long, and energy-conserving and environment-protective have good economic benefit and social benefit.

The specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further details.

Provide by Fig. 1 to Fig. 6, the utility model comprises the outlet main body, be cylindric in the outlet main body, outlet main body inboard is built into one by z type refractory brick 8 and wedge type insulating brick 2, there is the circular cast bed of material 3 outlet main body outside, external cylindrical portion has by the spraying bed of material 5, the first half outside cast bed of material 3 of outlet main body constitutes the semi-circular groove 9 concordant with the z shaped brick with fibrofelt 4, there is the cast bed of material 3 that tamps in the Lower Half outside of outlet main body with the concordant place of z type refractory brick, z type refractory brick and wedge type refractory brick 1 company of block.

The utility model in use, hot-blast outlet is inboard to be connected with the big-wall connecting portion, block is contained on big wall brick 7 and the petal brick 6, as Fig. 5, shown in Figure 6.

By said structure as can be seen, the utility model main body outer conical position, be to be filled to taper by watering material feeding, outside cylinder type position is topped by the spray paint spraying, the outside first half waters material feeding and fills the formation semi-circular groove concordant with the z shaped brick with fibrofelt, Lower Half is concordant with the z shaped brick waters material feeding and tamps, inboard and the big-wall connecting portion of hot-blast outlet, the fire-resistant brick company of z type refractory brick and arch form compares with existing equipment, has novel structure, uniqueness, good seal performance, lay bricks and do not hold in the palm, the life-span is long, energy-conserving and environment-protective.

In a word, the utility model is the modular tile by the structure uniqueness, fibrofelt and water the supporting filling of material feeding and be built into, brick and brick, brick and fibrofelt, brick and water between the material feeding close fit mutually, the outlet body is sturdy and durable, good airproof performance is not subjected to that cold and hot difference variation is big to be influenced, and lays bricks and can not hold in the palm, the air tight runout of pipeline, the production efficiency height saves production cost, long service life, reduce maintenance cost, avoided because of keeping in repair the economic loss that stopping production brings to enterprise, non-environmental-pollution helps the healthy of labourer, economic and social benefit is remarkable, is an innovation on the hot-blast stove pipeline.
