Abstract
The utility model provides a steam dewaxing kettle, relating to a precision casting tool. The utility model has the purpose of providing a steam dewaxing kettle with stable steam pressure. The steam dewaxing kettle provided by the utility model comprises a steam generating furnace, a dewaxing working chamber is sheathed in a furnace chamber of the steam generating furnace, a first vent pipe is communicated between the furnace chamber and the dewaxing working chamber, a first valve is arranged on the first vent pipe, a steam storage tank is arranged between the furnace chamber and the dewaxing working chamber, the steam storage tank is respectively connected with the furnace chamber and the dewaxing working chamber via a second vent pipe and a third vent pipe, and a second valve and a third valve are respectively arranged on the second vent pipe and the third vent pipe. The steam dewaxing kettle can continuously provide steam, ensure stable steam pressure and provide dewaxing effect.
Description
Technical field
The utility model relates to a kind of hot investment casting instrument, particularly relates to a kind of steam dewaxing still for the precision casting mold dewaxing.
Background technology
Existing precision-investment casting steam dewaxing still is directly given the dewaxing working chamber by the furnace chamber of Steam generating furnace with the steam air feed, and the dewaxing working chamber is the workspace, offers the higher vapour pressure of mould and temperature.Wax in the mould absorbs a large amount of heats when fusing outflow and formwork intensification, the working chamber pressure and temperature that causes dewaxing descends.Dewaxing working chamber pressure is low, and the wax material burn-off rate is slow, and wax causes formwork easily spalling under low vapour pressure from the solid-state volumetric expansion that produces to liquid state.The serious cracking of formwork affects the surface quality of foundry goods, batch seam that cast(ing) surface produces with regard to there being liquid steel water to flow into the crack at the position of cracking after the cast.The lighter need to polish and reprocess, and the serious foundry goods that causes is scrapped.
The utility model content
The technical problems to be solved in the utility model provides the stable steam dewaxing still of a kind of steam pressure.
The utility model steam dewaxing still, comprise Steam generating furnace, the furnace chamber inner sleeve removable wax working chamber of described Steam generating furnace, described furnace chamber is communicated with the first breather pipe with dewaxing between the working chamber, be provided with the first valve on described the first breather pipe, be provided with vapor storage between described furnace chamber and the described dewaxing working chamber, described vapor storage is communicated with by the second breather pipe, the 3rd breather pipe respectively with described furnace chamber and described dewaxing working chamber, and the second valve and the 3rd valve are set respectively on described the second breather pipe, the 3rd breather pipe.
Compared with prior art the utility model was provided with vapor storage before the furnace chamber of Steam generating furnace and the working chamber that dewaxes, after steam pressure, temperature in the dewaxing working chamber reaches working stamndard, steam in the furnace chamber can enter vapor storage, after steam pressure, the temperature of dewaxing working chamber reduce, be stored in steam in the vapor storage and just enter in the dewaxing working chamber steam is replenished, make steam pressure, temperature in the dewaxing working chamber remain at working stamndard.
The utility model steam dewaxing still, wherein said vapor storage is wrapped up in heat insulation layer outward, wraps up the loss that heat insulation layer can reduce the steam heat in the vapor storage in the vapor storage appearance.
The utility model steam dewaxing still, wherein said the first valve, the second valve, the 3rd valve are electromagnetic valve.Adopt electromagnetic valve to be because of easy to operate, the easy control of electromagnetic valve, to be quick on the draw.
Below in conjunction with accompanying drawing the utility model steam dewaxing still is described further.
Description of drawings
Fig. 1 is the utility model steam dewaxing still cut away view.
The specific embodiment
As shown in Figure 1, the utility model steam dewaxing still, comprise Steam generating furnace 1, the furnace chamber 11 inner sleeve removable wax working chambers 2 of Steam generating furnace 1, furnace chamber 11 is communicated with the first breather pipe 3 with dewaxing between the working chamber 2, be provided with the first valve 31 on the first breather pipe 3, be provided with vapor storage 4 between furnace chamber 11 and the dewaxing working chamber 2, the vapor storage 4 outer heat insulation layers 41 of wrapping up in, vapor storage 4 is passed through respectively the second breather pipe 5 with furnace chamber 11 and dewaxing working chamber 2, the 3rd breather pipe 6 is communicated with, the second breather pipe 5, the second valve 51 and the 3rd valve 61, the first valves 31 are set respectively on the 3rd breather pipe 6, the second valve 51, the 3rd valve 61 is electromagnetic valve.
The utility model in use, to be with the wax-pattern tool to put into dewaxing working chamber 2, open the first valve 31 on the first breather pipe 3, steam in the furnace chamber 11 of Steam generating furnace 1 enters dewaxing working chamber 2, the pressure and temperature of dewaxing working chamber 2 reaches operating temperature and the pressure of dewaxing, close the first valve 31, then open the second valve 51 on the second breather pipe 5, steam in the furnace chamber 11 enters in the vapor storage 4, reduce behind the wax in the thawing mould when the vapor (steam) temperature in the dewaxing working chamber 2 and pressure, open the 3rd valve 61 on the 3rd breather pipe 6, by the steam in the vapor storage 4 dewaxing working chamber 2 is carried out steam and replenish, make vapor (steam) temperature and pressure in the dewaxing working chamber 2 remain working stamndard.
Above-described embodiment is described preferred embodiment of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model all should fall in the definite protection domain of the utility model claims.
