Abstract
The utility model belongs to the technical field of preparing hard alloy, and discloses a disintegrated furnace for preparing hard alloy. The technical scheme mainly includes that the disintegrated furnace comprises a barrel-shaped casing, a rectangular barrel, a thermal preservation outer layer, an electric heating electrode, a seal door and a vacuum extractor. The rectangular barrel is made of graphite plates and arranged inside the barrel-shaped casing; the thermal preservation outer layer is wrapped by carbon fiber felts; the seal door and the vacuum extractor consist of a metal plate, and a carbon fiber felt plate, and a graphite plate. The disintegrated furnace with the structure solves the problems of lower heating efficiency by a disintegrated furnace barrel built by firebricks and environmental pollution by evacuation.
Description
Technical field
The utility model belongs to the preparing technical field of carbide alloy, discloses a kind of at the employed binder removal stove of carbide alloy preparation process specifically.
Background technology
Hart metal product at first utilizes paraffin rubber or plastics to make adhesive in process of production, and alloy powder is bonded together, and makes semifinished product, forms by a firing then.One of purpose that it is fired is exactly that the process high temperature in the semifinished product is made it to gasify and exclude.Present employed carbide alloy preparation is used the binder removal stove as shown in Figure 1, and its structure comprises the cylindrical shell 1 that is built into by refractory brick, is provided with the dawn 2 in the stainless steel in the inboard of cylindrical shell, is provided with to be used for the resistance wire 3 that electrically heated nichrome constitutes in refractory brick.When using the binder removal fire grate glue of this structure, at first hart metal product semifinished product 4 is arranged and inserted in the stainless steel in the dawn, connect power supply then,, make adhesive composition gasification, and combustion and emptying in the semifinished product feeding the combustion of hydrogen heating.Utilize the binder removal stove of said structure to realize that there is following defective in the discharge of adhesive in the carbide alloy: one, because in above-mentioned operation, adhesive composition burning with gasification, not only can produce unpredictalbe oxious component, and with above-mentioned harmful components emptying, therefore, can cause serious environmental to pollute, be unfavorable for the sustainable development of this industry; Secondly, the binder removal furnace tube that utilizes refractory brick to be built into is because its structural defective not only waste electric energy during use, but also the burning hydrogen inefficiency is a kind of with the binder removal stove that is eliminated.
The utility model content
The purpose of this utility model just provides a kind of rational in infrastructure, carbide alloy that efficient is high preparation binder removal stove.
For realizing that the technical scheme that the utility model purpose is adopted is:
A kind of carbide alloy preparation binder removal stove, the housing that comprises cartridge type, in described cartridge type housing, be provided with by what graphite cake constituted and be used to place the rectangle cylindrical shell for the treatment of binder removal carbide alloy semifinished product, at the outside of this graphite cake cylindrical shell and the inboard insulation of wrapping up in by the carbon felt energising heating electrode outer and that constitute by graphite cake that is respectively arranged with, be provided with the hermatic door body that constitutes by metallic plate, carbon felt plate and graphite cake that is connected with the shell hinge of cartridge type in the both sides of this graphite cake cylindrical shell; Described cartridge type housing is provided with vacuum extractor, and the two-port of this vacuum extractor is communicated with filter and described rectangle cylindrical shell respectively.
In addition, described energising heating electrode is made of the alternate graphite post that is connected with power supply respectively; The cross section of described rectangle cylindrical shell is a square; Described filter mechanism is made of four filter elements to Pyatyi; Described filter mechanism is provided with cooling body.
Carbide alloy preparation binder removal stove provided by the utility model, compare with prior art and to have the following advantages: one, because this carbide alloy preparation is made of the insulation graphite cake outer and anti-oxidation effect that the carbon felt constitutes with the body of heater of binder removal stove, and heating electrode plates directly is arranged on the furnace wall that is made of graphite cake, the body of heater of this structure is obviously much better than the heat insulation effect of the body of heater that is made of refractory brick, therefore, this body of heater is used for the efficiency of heating surface of carbide alloy semifinished product much higher; Its two because the preparation of this carbide alloy is provided with vacuum extractor with the binder removal stove, the two-port of this vacuum extractor is communicated with filter and rectangle cylindrical shell respectively; Therefore, the adhesive composition of heating and gasifying can be extracted out by vacuum device and enter the filter mechanism filtered and recycled, has avoided emptying and the environmental pollution that causes.

The specific embodiment
Below in conjunction with accompanying drawing the structure of carbide alloy preparation provided by the utility model with the binder removal stove is described in further detail:
Be depicted as the structural representation of carbide alloy preparation provided by the utility model as 2 figure with the binder removal stove.Its structure comprises the cartridge type housing 18 that has steel plate to make with supporting role, in this cartridge type housing, be provided with and be used to place the rectangle cylindrical shell 5 for the treatment of binder removal carbide alloy semifinished product, this cylindrical shell is made of the carbon felt 7 with good insulation effect on graphite cake 6 and parcel and its outer wall, just be provided with (shown in 3 figure) alternate several (size according to barrel space is decided) that are connected in the cylindrical shell that constitutes by graphite cake in power supply with power supply, the graphite post electrode 8 and 9 that negative pole 19 is electrically connected, be provided with cartridge type housing 18 hinged by metallic plate 10 in the both sides of this graphite cake cylindrical shell, the hermatic door body (shown in 4 figure) that carbon felt plate 11 and graphite cake 12 constitute, promptly close sealing Men Tike so that the rectangle cylindrical shell 5 that is made of graphite cake 6 forms a seal cavity, be used for the binder removal of heating of carbide alloy semifinished product 4; The structure that constitutes this binder removal stove also comprises and is arranged at the outer vacuum pumping pump 13 of cartridge type housing, and the suction mouth 14 of this vacuum pumping pump is communicated with the rectangle cylindrical shell through pipelines 15, extracts 16 in mouth out and is communicated with filter mechanism 17.
Its operation principle is: the carbide alloy semifinished product is inserted in the cartridge type housing 18, to graphite electrode energising heating and open vacuum pumping pump and filter, then the carbide alloy semifinished product is when being heating and curing, the adhesive of gasification is evacuated pump and extracts and enter the filter mechanism filtration out, reclaims the binder liq that obtains and can utilize once more after further checking.
In order to improve the containing quantity of carbide alloy semifinished product in the rectangle cylindrical shell, the cross section of this rectangle cylindrical shell is set to be square structure.
In order further to improve the rate of recovery of adhesive, four filter mechanisms 17 to Pyatyi are set, and cooling body 20 is set between filter mechanism.
