Abstract
The utility model relates to a vacuum sintering furnace and discloses a horizontal type vacuum degreasing and sintering furnace which comprises a furnace body, a support, a first rotation piece type vacuum pump, a second rotation piece type vacuum pump and a water ring vacuum pump. The support is fixedly provided with the first rotation piece type vacuum pump and the second rotation piece type vacuum pump which are mutually connected. The first rotation piece type vacuum pump is connected with the furnace body through a degreasing pipeline. The second rotation piece type vacuum pump is fixedly connected with the water ring vacuum pump fixed to the lower end of the support. The water ring vacuum pump is connected with a pneumatic cylinder. According to the horizontal type vacuum degreasing and sintering furnace, the two rotation piece type vacuum pumps are adopted for increasing the suction force so that waste gas in the furnace body and a binding agent can be fast pumped and separated, the working procedure of cleaning the degreasing pipeline many times each day in the past is changed into the working procedure of cleaning the degreasing pipeline one time each month, the labor force is saved, and the production efficiency is improved.
Description
Technical field
The utility model relates to vacuum sintering furnace, relates in particular to the degreasing sintered stove of a kind of horizontal vacuum.
Background technology
That vacuum degreasing fritting furnace is mainly used in is stainless steel-based, carbide alloy, high temperature alloy, high than the vacuum before the sintering such as alloy, cermet or carrier gas degreasing and high temperature sintering.Vacuum degreasing fritting furnace possesses degreasing and two kinds of functions of sintering simultaneously.The object of degreasing is away binding agent contained in molded blank; The object of sintering is to make the degreasing blank of porous be contracted to densification to become the goods with certain tissue and performance.Vacuum degreasing fritting furnace is equipped with degreasing system, and the pipeline of indispensability in degreasing duct type degreasing system.For molded blank binding agent in skimming processes does not remain in pipeline, need clean degreasing pipeline; But traditional equipment will clean once to twice in one day, the extremely low production efficiency that affects of operating efficiency.
Utility model content
Technical problem to be solved in the utility model is to provide the degreasing sintered stove of a kind of horizontal vacuum, overcomes the problem that in prior art, degreasing pipeline need repeatedly clean.
For solving the problems of the technologies described above, the utility model provides a kind of horizontal vacuum degreasing sintered stove, comprise body of heater, support, No. 1 rotary-vane vaccum pump, No. 2 rotary-vane vaccum pumps, water ring vacuum pump, on described support, be fixed with No. 2 rotary-vane vaccum pumps of interconnective No. 1 rotary-vane vaccum pump and increase, No. 2 rotary-vane vaccum pumps of interconnective No. 1 rotary-vane vaccum pump and increase can increase suction, and gas and binding agent in body of heater are better discharged; And described No. 1 rotary-vane vaccum pump is connected with described body of heater by degreasing pipeline, described No. 2 rotary-vane vaccum pumps are fixedly connected with the water ring vacuum pump that is fixed on described support lower end again, and described water ring vacuum pump is connected with pneumatic cylinder again.
Further, on described pneumatic cylinder, be respectively equipped with gas outlet and discharge outlet, the waste gas and the waste water that produce for discharging the utility model.
Further, on described No. 2 rotary-vane vaccum pumps, be also provided with Pressure gauge, Pressure gauge is controlled to operate for detection of gas flow.
Further, described degreasing pipeline is connected by flange with described body of heater and described No. 1 rotary-vane vaccum pump respectively, connects the air-tightness that can guarantee that each several part connects by flange, makes blank obtain better degreasing effect.
The beneficial effects of the utility model are: the utility model adopts two rotary-vane vaccum pumps to increase suction, waste gas in body of heater and binding agent can be detached fast, the original operation of time cleaning and degreasing pipeline is more than a day become and clear up once January, not only saved labour but also improved production efficiency.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is that this uses novel right view.
In figure: 1, body of heater; 2, degreasing pipeline; 3, No. 1 rotary-vane vaccum pump; 4, No. 2 rotary-vane vaccum pumps; 5, Pressure gauge; 6, support; 7, water ring vacuum pump; 8, gas outlet; 9, pneumatic cylinder; 10, discharge outlet.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further set forth.
As depicted in figs. 1 and 2, the degreasing sintered stove of a kind of horizontal vacuum, comprise body of heater 1, support 6, No. 1 rotary-vane vaccum pump 3, No. 2 rotary-vane vaccum pumps 4, water ring vacuum pump 7, on support 6, be fixed with by 3 and No. 2 rotary-vane vaccum pumps 4 of interconnective No. 1 rotary-vane vaccum pump of flange, and No. 1 rotary-vane vaccum pump 3 is connected with body of heater 1 by degreasing pipeline 2, No. 2 rotary-vane vaccum pumps 4 that the utility model increases combine and detach binding agent and waste gas with No. 1 rotary-vane vaccum pump 3, the glue residue amount increasing in degreasing pipeline 2 along with suction will reduce greatly, the daily wash number of degreasing pipeline 2 is become and cleared up once from the original operation of time cleaning and degreasing pipeline more than a day January, not only save labour but also improved production efficiency.No. 2 rotary-vane vaccum pump 4 is fixedly connected with the water ring vacuum pump 7 that is fixed on support 6 lower ends again, and water ring vacuum pump 7 is connected with pneumatic cylinder 9 again.
As shown in Figure 2, on pneumatic cylinder 9, be also respectively equipped with gas outlet 8 and discharge outlet 10, in the time that body of heater 1 carries out sintering, internal high temperature is melted binding agent, also can produce some waste gas and waste water simultaneously, in the time that 3 and No. 2 rotary-vane vaccum pumps 4 of No. 1 rotary-vane vaccum pump are extracted out, proceed to pneumatic cylinder 9 sides of carrying out run in removing exhaust gas and waste water.
As shown in Figure 1, wherein on No. 2 rotary-vane vaccum pumps 4, be also provided with Pressure gauge 5, Pressure gauge 5 is in order to observe the pump housing and pipeline gas flow, when gas flow larger, higher to the operation requirements of body of heater and each parts; Degreasing pipeline 2 is connected by flange with 1 and No. 1 rotary-vane vaccum pump 3 of body of heater respectively, guarantees connective stability and air-tightness, prevents from causing degreasing because gas leakage participates in unnecessary air and detaching binding agent failure.
In the time that degreasing sintered furnaceman does, increase suction by No. 1 rotary vane type vacuum 3 pumps and No. 2 rotary-vane vaccum pump 4 actings in conjunction the impurity in degreasing pipeline 2 is discharged smoothly, reduce wash number, thereby enhance productivity.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present utility model; in the prerequisite that does not depart from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent.
