Ask, the suitable hot off-square formula of selection, Vacuum Heat is de- or atmosphere heat is de-, according to the technical requirements of client, reaches pre- before sintering
Burn work.
The existing de- stove function of heat is single, only takes off function with Vacuum Heat, or only has the de- function of atmosphere heat.Such as
Fruit needs two kinds of functions to be accomplished by purchasing two kinds of equipment simultaneously.Therefore need a kind of set Vacuum Heat of offer de- and atmosphere hot de- two
Person is in the de- furnace apparatus of heat of one, if developed, set Vacuum Heat is de- and atmosphere heat takes off both and takes off furnace apparatus in the heat of one,
Two kinds of functions can be possessed by only needing to purchase an equipment, optimized device configuration, simplified cost.
The content of the invention
The invention provides a kind of vacuum and the de- furnace apparatus of atmosphere dual-purpose type heat, purpose is designed and developed：This cluster tool
Vacuum Heat is de- and de- two functions of atmosphere heat are in one, can be produced according to the different production technologies of the demand of client progress and meet visitor
The product that family is required；And the configuration of the equipment optimized, has saved cost.
The invention provides following technical proposals：A kind of de- furnace apparatus of vacuum and atmosphere dual-purpose type heat, including base of furnace body,
Body of heater component, the body of heater component is connected with the base of furnace body, and the body of heater component includes body of heater outer cover, calandria, body of heater
Inner cover, Support bracket, the body of heater outer cover, calandria, body of heater inner cover, Support bracket are fixedly connected with the base, described
Body of heater inner cover is placed in the inner chamber of the body of heater outer cover, and the Support bracket is placed in the interior cover chamber of the body of heater inner cover, described
Calandria is fixedly connected with the inwall of the outer cover, and the case of the body of heater inner cover is connected with charge valve, the body of heater inner cover
Bottom is connected with wax storage, and the body of heater inner cover is connected with airduct one end, and the other end of the airduct is connected with vavuum pump, described
Airduct is installed on igniter.
The de- furnace apparatus of vacuum and atmosphere dual-purpose type heat also includes thermocouple, and the thermocouple connects with the body of heater outer cover
Connect.
The de- furnace apparatus of vacuum and atmosphere dual-purpose type heat also includes explosion-proof valve, the explosion-proof valve and the body of heater inner cover

Beneficial effects of the present invention are as follows：Body of heater inner cover 4 is taken out using vavuum pump 9 when needs produce when containing carbon products
Vacuum so that product carries out heating pre-burning under vacuum, preserves the carbon in product；When needing to produce without carbon products from filling
Air valve 7 is filled with air so that product carries out heating pre-burning under the conditions of oxygen-containing air, removes the carbon in product；But need to provide
When high-quality product inert gas is filled with from charge valve 7.Therefore this cluster tool Vacuum Heat is de- and atmosphere heat is de-
Two functions can carry out different production technologies according to the demand of client and produce the product met the requirements of the customers in one；And
The configuration of the equipment of optimization, has saved cost.
Brief description of the drawings
Fig. 1 is vacuum of the present invention and the de- furnace apparatus of atmosphere dual-purpose type heat.
Fig. 2 be in Fig. 1 A-A to sectional view.
