Abstract
The utility model discloses the circulative convection structure of large-scale annealing crucible oven, interior bucket is provided with in furnace shell, guide shell is provided with in interior bucket, furnace shell top is provided with bell, circulative convection gap is formed between described interior bucket inwall and guide shell outer wall, Hot-air fan is provided with below guide shell, the gap of 90mm-110mm is formed bottom guide shell and between Hot-air fan, this gap location is provided with a ring-shaped sealing sleeve, this ring-shaped sealing sleeve is just arranged above-mentioned Hot-air fan, form backflow gap between ring-shaped sealing sleeve and Hot-air fan, the inner homogeneous of ring-shaped sealing sleeve is distributed with the oblique flow deflector of 8-14 sheet.Transformation Posterior circle convection effects is improved obviously, top and the bottom homogeneous temperature in stove, in stove, product decarburization situation is reduced in present 10-20 silk by original 60-70 silk, effectively raise the consistence of the top and the bottom strength of materials, substantially reduce process treatment time, reduce warm-up time, reduce energy consumption, ensure that the quality of product.
Description
Technical field
The utility model relates to the technical field of annealing crucible oven, a kind of stove internal recycle convective structure specifically, the particularly mechanical connecting structure of its body of heater inner chamber.
Background technology
Hot-air fan principle of work is sucked from guide shell center by hot blast to blow to top by bottom again, forms circulative convection effect, makes upper and lower temperature in stove consistent, thus ensure that the intensity of top and the bottom material is consistent.Between structure guide shell originally and Hot-air fan, gap is larger at about 100mm, the hot blast of 50% is had from the clearance backflow of guide shell and Hot-air fan when circulating air, do not loop back stove top, reduce the effect of circulative convection, cause top and the bottom temperature in stove inconsistent, cause top and the bottom strength of materials deviation comparatively large, affect quality product.
Summary of the invention
The purpose of this utility model is the circulative convection structure providing large-scale annealing crucible oven, improves the strength variance up and down between material caused because annealing earthenware stove upper and lower temperature difference is large.
Overcome the shortcoming and defect existed in prior art.
To achieve these goals, the technical solution of the utility model is: the circulative convection structure of large-scale annealing crucible oven, comprise furnace shell, interior bucket is provided with in furnace shell, guide shell is provided with in interior bucket, furnace shell top is provided with bell, it is characterized in that: between described interior bucket inwall and guide shell outer wall, form circulative convection gap, Hot-air fan is provided with below guide shell, the gap of 90mm-110mm is formed bottom guide shell and between Hot-air fan, this gap location is provided with a ring-shaped sealing sleeve, this ring-shaped sealing sleeve is just arranged above-mentioned Hot-air fan, backflow gap is formed between ring-shaped sealing sleeve and Hot-air fan, the inner homogeneous of ring-shaped sealing sleeve is distributed with the oblique flow deflector of 8-14 sheet.
The utility model discloses the circulative convection structure of large-scale annealing crucible oven, circulative convection is obviously effect improved, top and the bottom homogeneous temperature in stove, in stove, product decarburization situation is reduced in present 10-20 silk by original 60-70 silk, effectively raise the consistence of the top and the bottom strength of materials, substantially reduce process treatment time, reduce warm-up time, reduce energy consumption, ensure that the quality of product.This transformation project is at home and abroad in a leading position in similar annealing furnace level.

Embodiment
With reference to the accompanying drawings, the utility model is described further.
The utility model is the circulative convection structure of large-scale annealing crucible oven, comprise furnace shell 1, interior bucket 2 is provided with in furnace shell 1, guide shell 3 is provided with in interior bucket 2, furnace shell 1 top is provided with bell 4, it is characterized in that: between described interior bucket 2 inwall and guide shell 3 outer wall, form circulative convection gap 5, Hot-air fan 6 is provided with below guide shell 3, bottom guide shell 3 and form the gap 7 of 90mm-110mm between Hot-air fan 6, this gap 7 place is provided with a ring-shaped sealing sleeve 8, this ring-shaped sealing sleeve 8 is just arranged above-mentioned Hot-air fan 6, backflow gap 9 is formed between ring-shaped sealing sleeve 8 and Hot-air fan 6, the height of backflow gap 9 is at about 4mm-6mm, the inner homogeneous of this ring-shaped sealing sleeve 8 is distributed with the oblique flow deflector of 8-14 sheet, the oblique flow deflector of described 8-14 sheet is that divergent shape diagonally distributes.Recirculating air is guided to guide shell circulation air path, makes it effective in circulative convection process and block the hot blast originally refluxed from Hot-air fan and guide shell gap location, greatly strengthen circulative convection effect.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that the utility model is specifically implemented to be confined to these explanations above-mentioned.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, some simple deduction or replace can also be made, all should be considered as belonging to protection domain of the present utility model.
