The cold sintering furnace of protective atmosphere speed
Technical field
The utility model relates to a kind of equipment, especially a kind of under protective atmosphere the equipment of sintered products.
Background technology
In the production process of diamond metal grinding tool, must use heat-agglomerating equipment.Diamond metal grinding tool, because itself characteristic need to be sintered to 800 DEG C of left and right, starts to occur carbonization and common diamond is heated to 700 DEG C under aerobic environment, and metal powder also needs to do anti-oxidation processing.Therefore will relate to one and can pass into protective atmosphere, there is the agglomerating plant of airtight cavity.Product sintering finishes simultaneously, need to reach energy cooling effect fast under protective atmosphere, to enhance productivity, economizes on resources.
Utility model content
Finish the many and inefficient deficiency of cooling slow, waste material, energy consumption in order to overcome under protective atmosphere product sintering; the utility model provides a kind of protective atmosphere speed cold sintering furnace; this sintering furnace can ensure product sintering under protective atmosphere in use; cooling effect fast after reaching sintering and completing, saves material, the energy simultaneously and raises the efficiency.
For achieving the above object, the utility model solves the technical scheme that its technical problem adopts and is:
The cold sintering furnace of protective atmosphere speed; comprise chamber type electric resistance furnace, stainless steel cavity, thermal insulation layer and circulating cooling water tank; stainless steel cavity airtight end puts in chamber type electric resistance furnace; mid portion is wrapped up by thermal insulation layer; openend has circulating cooling water tank, and stainless steel cavity hatch seals with dismantled and assembled stainless steel fire door.
As the technical scheme of further improvement of the utility model, the dismantled and assembled stainless steel fire door of described stainless steel cavity, with being no less than 8 openends that are bolted to stainless steel cavity, has the rubber washer as sealing use between stainless steel fire door and stainless steel cavity.
As the technical scheme of further improvement of the utility model, in described stainless steel cavity, protective atmosphere air inlet, in upper end, stainless steel cavity middle part, communicates with inner chamber, and gas outlet is in stainless steel fire door bottom.
As the technical scheme of further improvement of the utility model, described recirculated cooling water case and bag are rolled in stainless steel cavity hatch end, and recirculated cooling water, from the water inlet of water tank lower water inlet, is discharged from water tank upper delivery port.
As further improved technical scheme of the present utility model, described product, after the heat-agglomerating of chamber type electric resistance furnace end finishes, moves to circulating cooling water tank end place, realizes product cooling rapidly under protective atmosphere.
In sum, the beneficial effects of the utility model are: ensure that product sintering character under protective atmosphere is good, it is cooling fast that sintering finishes rear realization, economizes on resources and enhance productivity.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further.
The cold sintering furnace of protective atmosphere speed as shown in Figure 1 to Figure 3, comprises chamber type electric resistance furnace (1), stainless steel cavity (2), thermal insulation layer (3) and circulating cooling water tank (4).Described stainless steel cavity (2) sealed end puts in chamber type electric resistance furnace (1), mid portion is wrapped up by thermal insulation layer (3), openend has circulating cooling water tank (4), stainless steel cavity (2) opening has dismantled and assembled stainless steel fire door (5) sealing, as shown in Figure 5.The dismantled and assembled stainless steel fire door (5) of described stainless steel cavity (2), with being no less than 8 openends that are bolted to stainless steel cavity (2), has the rubber washer (6) as sealing use between stainless steel fire door (5) and stainless steel cavity (2).In described stainless steel cavity (2), pass into protective atmosphere air inlet (7) in upper end, stainless steel cavity (2) middle part, communicate with inner chamber, gas outlet (10) are in stainless steel fire door (5) bottom.Described circulating cooling water tank (4) is wrapped in stainless steel cavity (2) openend, and recirculated cooling water, from the water inlet of water tank lower water inlet, is discharged from water tank upper delivery port.Described product (8), after the heat-agglomerating of chamber type electric resistance furnace (1) end finishes, moves to circulating cooling water tank (4) end product (9) and locates, and realizes the cooling rapidly of under protective atmosphere product.
The chamber type electric resistance furnace (1) of the cold sintering furnace of the utility model protective atmosphere speed is ordinary procedure controlling resistance heating furnace, and stainless steel cavity (2) sealed end passes in chamber type electric resistance furnace (1).Stainless steel cavity (2) is to be welded by the stainless steel of thick about 8mm, has fire-resistant oxidation resistant performance, and only one end has and can open fire door.Between stainless steel fire door (5) and stainless steel cavity (2), there is the rubber washer (6) as sealing use, airtight rear air tight.Described thermal insulation layer (3) is to prevent that heat energy runs off, reduces the effect of stove surface temperature in a large number while playing heating, is to cover parcel with fire clay to make, and skin is fixed with aluminium skin.Described circulating cooling water tank (4) is to be wrapped in stainless steel cavity (2) openend, directly contacts with stainless steel shell cavity.
The occupation mode of the cold sintering furnace of the utility model protective atmosphere speed is:
The vessel that product is housed are positioned over to the interior sealed end of stainless steel cavity (2) (8) and locate, load onto stainless steel fire door (5) and screw 8 bolts (11) guarantee sealing.Open air accumulator valve, ventilation end (7) passes into protective atmosphere 30 minutes, and atmosphere to be protected can be covered with in whole cavity.Open chamber type electric resistance furnace (1) power supply and start to heat up, by conducting heat stainless steel cavity (2) heating, and by product sintering in cavity.After product sintering finishes, ON cycle cooling water tank (4) recirculated water, moves to stainless steel fire door end (9) by the vessel that product is housed and locates to carry out cooling.Be cooled to after suitable temperature, close protective atmosphere breather valve and recirculated cooling water, open fire door (5) product is taken out.
Described in the utility model, concrete case study on implementation is only better case study on implementation of the present utility model, is not used for limiting practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modify, all should serve as technology category of the present utility model.
