Abstract
The utility model provides the technical proposal of a bell tempering furnace, which can be used for heating metal parts by protective gases. The technical proposal is characterized in that the utility model is provided with a stainless steel inner cover; the inner cover is arranged on a base seat; the surrounding of the inner cover is provided with a sand sealing groove; an outer cover is covered on the sand sealing groove; a centrifugal blower is arranged on the center position on the base seat in the stainless steel inner cover; the surrounding of the centrifugal blower is provided with an electric heater; annular partition plates are arranged on the centrifugal blower and the electric heater; a material frame is arranged on the partition plates; the main shaft of the centrifugal blower is connected with a motor arranged below the base seat.
Description
The utility model relates to a kind of heat-treatment furnace, especially a kind of metal parts that is used for is at the annealing, the tempering bell tempering furnace that charge into the protective gas heating.
Bell tempering furnace in the prior art also has an inner cover; processed metal parts is contained in its inner cover, and fills with protective gas, and outer cover is to be made by steel plate and refractory material; electric heater just is arranged on the inwall of outer cover, so outer cover plays the double action of insulation and thermal source.This structure has the too heavy problem of outer cover self inevitably, and the crane gear that in use requires to have certain elevating capacity just can.
The purpose of this utility model is exactly at the existing in prior technology problem, and provides a kind of metal parts that is used for by interior bell tempering furnace technical scheme of filling the protective gas heating.
For clearly demonstrating the technical characterstic of this programme, now by a specific embodiment, and in conjunction with its accompanying drawing, the technical characterictic of this programme is described in detail.
Description of drawings:
Accompanying drawing 1 is the structural representation of the utility model embodiment.
By accompanying drawing as can be seen, the bell tempering furnace of this programme, outer cover 4 and a stainless steel inner cover 5 when having one to have suspension ring 11, described stainless steel inner cover 5 is to be located in one to have on the base 2 of boss, around the stainless steel inner cover 5 is sand sealing groove 3, outer cover 4 promptly covers on the sand sealing groove 3, is used for sealing the space between stainless steel inner cover 5 and the outer cover 4, so that insulation.Centre in the cover of stainless steel inner cover 5 on the base 2, centrifugal fan 8 is arranged, around centrifugal fan 8 is electric heater 9, on centrifugal fan 8 and electric heater 9, toroidal membrane 7 is arranged, then be placed with bin 6 on the dividing plate 7, the main shaft of described centrifugal fan 8 is connected with motor 1 under the base 2.Described centrifugal fan 8 and electric heater 9 also can be placed on the top of bin 6, its effect be the same 6 times at bin.Junction at described stainless steel inner cover 5 and base 2 also has sealing ring 10, the sealing when guaranteeing in inner cover 5 inflation.
The bell tempering furnace of said structure; because electric heater is within inner cover; force the protective gas circulation that charges into the centrifugal fan that places the electric heater center again, make heat be taken away and be passed to heated part by protective gas, case temperature can promote and balance faster.Outer cover is because no longer play the double action of thermal source and insulation, and has been an insulation effect, so all can lower the requirement at aspects such as thickness, this can alleviate himself weight greatly.This internal heat type structure has not only alleviated the weight of outer cover, but also has saved electric power, has reduced energy resource consumption.This shows, the utility model compared with prior art, its effect then is conspicuous.
Claims (2)
