Abstract
The utility model discloses a tantalum capacitor vacuum sintering dewaxing furnace which mainly comprises a furnace body, a furnace cover, a furnace pipe and a degreasing trapping system. The furnace cover is connected with the furnace body through a furnace cover lifting mechanism and is arranged right above the furnace body, the furnace pipe is arranged inside the furnace body, a heater and a hoisting workpiece charging basket are arranged inside the furnace pipe, and the degreasing trapping system is connected with the furnace body through a pipeline. The tantalum capacitor vacuum sintering dewaxing furnace is characterized in that a muffle tank is arranged inside the furnace pipe, the hoisting workpiece charging basket is arranged inside the muffle tank, an extraction opening is formed in the bottom of the muffle tank, and the extraction opening is connected with the pipeline. A charging port is arranged at the side wall of an upper portion of the furnace body, and inert gases are flowed into the furnace body. During the process of dewaxing of a product, when temperature inside the furnace rises, aerated gases and gases generated through dewaxing are pumped out along the direction of the bottom of the muffle tank, and therefore a binder generated in high temperature does not volatilize to a furnace internal heating chamber and a furnace wall, formation of pollution is avoided, cleaning frequency of the dewaxing furnace is reduced, and the tantalum capacitor vacuum sintering dewaxing furnace effectively improves quality of the product.
Description
Technical field
The utility model relates to a kind of tantalum electric capacity vacuum-sintering dewaxing furnace, especially a kind ofly is easy to obtain high quality of products, efficient height, the low tantalum electric capacity vacuum-sintering dewaxing furnace of the cleaning frequency.
Background technology
What present tantalum electric capacity sintering dewaxing furnace adopted is internal heat type, product is in the intensification dewaxing process, body of heater inside is in the condition of high temperature, because high temperature action, the binding agent of volatilization can be to cold direction bonding, and the body of heater wall adopts the water flowing cooling, so a large amount of binding agents can evaporate on the furnace wall, the binding agent that is stained with can form cold well effect and no longer volatilize the severe contamination heating clamber, the contaminated phenomenon of workpiece that has dewaxing when making the second stove product sintering, thereby the control of the difficult quality of product.In addition, the product time problem for the quality that guarantees product as much as possible adopts present dewaxing furnace often to burn several stoves and just must clear up, but it is loaded down with trivial details to exist dismounting, the situation of labor intensive.
The utility model content
Technical problem to be solved in the utility model provides a kind of tantalum electric capacity vacuum-sintering dewaxing furnace, by Muffle pot is set, and in the Muffle pot bottom bleeding point is set in body of heater, improves the gas communication direction, thereby obtain high-quality product, reduce the cleaning frequency simultaneously.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of tantalum electric capacity vacuum-sintering dewaxing furnace, mainly comprise body of heater, bell, flue and degreasing trapping system, bell links to each other with body of heater by furnace cover lifting mechanism and places directly over the body of heater, flue places body of heater inside, be provided with heater and lifting workpiece charging basket in the flue, the degreasing trapping system links to each other with body of heater by pipeline, it is characterized in that; Be provided with Muffle pot in the described flue, described lifting workpiece charging basket is arranged in Muffle pot, and described Muffle pot bottom is provided with bleeding point, and described bleeding point links to each other with pipeline; Described upper of furnace body sidewall is provided with inflation inlet, wherein passes to inert gas.
Further, described heater is to be arranged at the Muffle pot outside along the circumferential direction to go up the cylindrical shape chip heater that distributes.Further, described degreasing trapping system is made up of degreasing trap, the cold well of capture and isolator.Advantage of the present utility model is: by in the dewaxing body of heater Muffle pot being set, and have a bleeding point in Muffle pot bottom, have inflation inlet on sidewall of the furnace body top, thereby product is in the process of dewaxing, when temperature in the stove raises, the gas that the gas that charges in the stove and dewaxing produce can be taken away by the bleeding point of bottom, this moment is because the air pressure in the body of heater will be higher than the air pressure of Muffle pot inside, and the direction of bleeding is the bottom direction along Muffle pot, so the binding agent that high temperature produces can not evaporate on the interior heating clamber of stove and the furnace wall, avoid the formation of polluting, reduced the dewaxing furnace cleaning frequency.Also can not there be the situation of pollution in the second stove product sintering, thereby has improved the quality of product effectively.
By the heater in the body of heater being arranged at the Muffle pot outside and for along the circumferential direction going up the cylindrical shape chip heater that distributes, strengthening swept area, thereby improved temperature uniformity, be conducive to the raising of product sintering quality.
The degreasing trapping system is made up of degreasing trap, the cold well of capture and isolator, is used in combination by adopting the three, improves to capture effect, thereby has reduced the cleaning frequency.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of a kind of tantalum electric capacity of the utility model vacuum-sintering dewaxing furnace.
The specific embodiment
A kind of tantalum electric capacity vacuum-sintering dewaxing furnace shown in Figure 1 comprises body of heater 1, bell 2, flue 3, Muffle pot 4, degreasing trapping system 5, furnace cover lifting mechanism 6, lifting workpiece charging basket 7, heater 8, bleeding point 9, inflation inlet 10, degreasing trap 11, captures cold well 12, isolator 13.
Illustrated a kind of tantalum electric capacity vacuum-sintering dewaxing furnace, mainly comprise body of heater, bell, flue, Muffle pot and degreasing trapping system, bell links to each other with body of heater by furnace cover lifting mechanism and places directly over the body of heater, flue places body of heater inside, is disposed with lifting workpiece charging basket, Muffle pot and heater in the flue from inside to outside.The Muffle pot bottom is provided with bleeding point, and on sidewall of the furnace body top inflation inlet is set, and in inflation inlet, pass to inert gas, thereby product is in the process of dewaxing, when temperature in the stove raises, the gas that the gas that charges in the stove and dewaxing produce can be taken away by the bleeding point of bottom, this moment is because the air pressure in the body of heater will be higher than the air pressure of Muffle pot inside, and the direction of bleeding is the bottom direction along Muffle pot, so the binding agent that high temperature produces can not evaporate in the stove on the heating clamber and furnace wall, avoid the formation of polluting, reduced the dewaxing furnace cleaning frequency, and also can not there be the situation of pollution in the second stove product sintering, thereby has improved the quality of product effectively.
The degreasing trapping system links to each other with body of heater by pipeline, mainly is made up of degreasing trap, the cold well of capture and isolator, utilizes the three effectively to make up, and improves to capture effect, has reduced the cleaning frequency.In addition, by the heater in the body of heater being arranged at the Muffle pot outside and for along the circumferential direction going up the cylindrical shape chip heater that distributes, strengthening swept area, thereby improved temperature uniformity, be conducive to the raising of product sintering quality.
