Abstract

The utility model discloses a bell-type annealing furnace, which is provided with a base, wherein an outer cover, a heater and a dome are arranged on the base, and circulating fans are arranged on the outer cover. The bell-type annealing furnace is characterized in that the base and the outer cover take matched ellipses, and the circulating fans are two and are respectively installed on two focuses of the ellipses on the top of the outer cover. The bell-type annealing furnace has simple structure, small occupied area, long service life, high production efficiency and high yield, and is an ideal metal heat processing device.

Description

A kind of bell type annealing furnace
Technical field
The utility model relates to the metallic substance heat treatment furnace, relates in particular to the nonferrous materials Equipment for Heating Processing of a kind of less energy-consumption, high production.
Background technology
Saving energy and reduce the cost and be not only the behavior that country advocates energetically, also is the effective means that enterprise reduced production costs, improved the overall competitive power of enterprise simultaneously.Present normally used bell type annealing furnace shape is in the majority with circle, generally is made up of heating mantles, stove seat etc., and well heater is set on the heating mantles, is generally electric heater or combustion heater, and the bonnet top is provided with recirculation blower, and the protective gas in the inner cover is flowed.During annealing; by the heat that is arranged on the heater fed on the heating mantles; thermal radiation by inner cover comes the heating of metal material; blower fan circulates the protective gas in the inner cover; transmission of heat by convection is strengthened in slit between metallic substance and convection current plate; improve rate of heating, and make every effort to about the even metallic substance, inside and outside temperature.The problem that existing circular bell type annealing furnace mainly exists in actual applications is: because the forced convection that only depends on radiation and separate unit blower fan to produce is heated to metallic substance, make the annealing cycle long, furnace output is low, thermo-efficiency is not high, energy consumption increases, metallic substance temperature inequality makes the internal and external temperature difference of metallic substance bigger.
Summary of the invention
The purpose of this utility model is: overcome the deficiencies in the prior art, can satisfy the metal heat treatmet requirement thereby provide a kind of, can reduce energy consumption simultaneously, guarantee the raising of production capacity, reach the bell type annealing furnace of energy-saving and cost-reducing purpose.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of bell type annealing furnace, have base, and outer cover is arranged above the base, well heater, pod has recirculation blower above the outer cover, it is characterized in that: described base and outer cover are the ellipse that is complementary; Described recirculation blower has two, is installed on respectively on two focuses of outer cover top ellipse.
Therefore, the beneficial effects of the utility model are: owing to adopted oval outer cover, production efficiency is improved greatly, single dome formula of the power ratio of oval bell type annealing furnace annealing furnace is twice, and production capacity has reached nearly three times, has reduced energy consumption of unit product; Two blower fan heating tech are adopted at the outer cover top, have better eliminated the temperature dead angle, have fully guaranteed product annealed homogeneity, guarantee annealing quality.Annealing furnace structure is simple, and floor space is little, long service life, and the production efficiency height, the production capacity height is a kind of ideal metal heat treatmet equipment.
Description of drawings
Accompanying drawing 1 is a kind of main pseudosection of the present utility model;
Accompanying drawing 2 is top plan view of Fig. 1.
Embodiment
Below by embodiment also in conjunction with the accompanying drawings, the technical solution of the utility model is further described in detail.
Embodiment:
Bell type annealing furnace as shown in Figure 1 and Figure 2, by oval-shaped base 4, the furnace bottom stopping composition, the oval outer cover 2 that is complementary with oval-shaped base, filamentary material, pod are arranged in the outer cover, two recirculation blowers 1 are adorned at outer cover 2 tops, are installed on respectively on two focuses of outer cover 2 top ellipses, remain annealed metallic substance 3 in the outer cover.During annealing, two recirculation blowers 1 turn round simultaneously, can quicken gas flow in the cover, make the interior temperature of stove even.Because base 4 is oval, is compared to circle, can increase the twice batch, has improved production capacity greatly, has effectively improved production efficiency.The utility model adopts two blower fan heating tech, has better eliminated the temperature dead angle, has fully guaranteed product annealed homogeneity, has improved quality product.
