13 pipe electric furnaces of prior art are through artificial opening and closing fire door, and the obvious efficient of this technology is not high, takes time and effort.
Summary of the invention
The purpose of the utility model is in order to overcome the deficiency of prior art, and a kind of tungsten powder reduction apparatus of automation control dodge gate is provided, and the controller of its motorized not only can well play the effect of control dodge gate, and time saving and energy saving.
The technical scheme of the utility model is:
A kind of tungsten powder reduction apparatus; Comprise heat-insulation layer, boat, cooling water pipe, boiler tube, electrode, furnace shell, hydrogen inlet, hydrogen outlet, dodge gate, electric controller, connecting rod, wherein: boat is located in the graphite-pipe successively, and cooling water pipe is located at the outer end of graphite-pipe; Graphite-pipe is located in the heat-insulation layer; Heat-insulation layer is located in the furnace shell, and electrode is located at the two ends of furnace shell, and hydrogen inlet and hydrogen outlet are located at the two ends of boiler tube respectively; Electric controller covers the import department of boiler tube one end through connecting rod control dodge gate when dodge gate is closed.
This tungsten powder reduction apparatus mainly is made up of heat-insulation layer, boat, cooling water pipe, boiler tube, electrode, furnace shell, hydrogen inlet, hydrogen outlet, dodge gate, electric controller, connecting rod.Boat is located in the boiler tube successively; Cooling water pipe is located at the outer end of boiler tube and is used for to the body of heater cooling, and heat-insulation layer is located at and is used for the temperature of protecting the tungsten powder reduction process required in the furnace shell, and the two ends that electrode is located at furnace shell are used for switching on to body of heater; Link to each other with each parts in the body of heater; Hydrogen inlet and hydrogen outlet are located at the two ends of boiler tube respectively, are used for making hydrogen to participate in the entire reaction course, and electric controller is through connecting rod control dodge gate; Electric controller button can nature the switch of control dodge gate, cover the import department of boiler tube one end when dodge gate is closed.
The advantage of the utility model is: can automation accurately control dodge gate, make that efficient is higher, more time saving and energy saving in the tungsten powder reduction process.
Description of drawings
Fig. 1 is the cross-sectional view of the utility model.
Reference numeral: heat-insulation layer 1, boat 2, cooling water pipe 3, boiler tube 4, electrode 5, furnace shell 6, hydrogen inlet 7, hydrogen outlet 8, dodge gate 9, electric controller 10, connecting rod 11.
The specific embodiment
Embodiment 1, a kind of tungsten powder reduction apparatus; Comprise heat-insulation layer 1, boat 2, cooling water pipe 3, boiler tube 4, electrode 5, furnace shell 6, hydrogen inlet 7, hydrogen outlet 8, dodge gate 9, electric controller 10, connecting rod 11, wherein: boat 2 is located in the graphite-pipe 4 successively, and cooling water pipe 3 is located at the end outside the graphite-pipe 4; Graphite-pipe 4 is located in the heat-insulation layer 1; Heat-insulation layer 1 is located in the furnace shell 6, and electrode 5 is located at the two ends of furnace shell 6, and hydrogen inlet 7 and hydrogen outlet 8 are located at the two ends of boiler tube 4 respectively; Electric controller 10 is through connecting rod 11 control dodge gates 9, and dodge gate 9 covers the import department of boiler tube 4 one ends when closing.
Boiler tube 4 is processed by the stainless steel tube of 5 millimeters thick, divides 2 rows up and down, on arrange 7; Under arrange 6, calandria is 6 millimeters a nickel filament, and four heating tapes are arranged; Every band furnace temperature is controlled by instrument automatically, the secondary reduction operation when this stove is used for that two stages, reducing process was produced tungsten powder more.
13 pipe electric furnace basic mechanical design features are following: 76 * 6750 millimeters of boiler tube size: Φ.Furnace power: 300 kilowatts.Heating belt length: 4800 millimeters.Supply voltage: 380 volts.Maximum operating temperature: 1100 ℃.Appearance and size: 9034 * 2130 * 2020 millimeters.The boat size: 240 * 40 * 25 millimeters, the characteristics of 2 millimeters these stoves of thickness of slab are that caliber is little, are easy to sealing, push away speed evenly, and can adjust arbitrarily, and this furnace temperature is more even, and products obtained therefrom grain number is more even.
Slowly send in the boiler tube uniformly the boat that fills the tungsten oxide raw material 2; Whole passing process can be according to user's request; Carry out the adjustment of technology, such as the adjustment of the speed of passing, the adjustment of temperature in the boiler tube; The particle of tungsten oxide raw material also can be different according to process choice particle diameter, tungsten oxide finally can obtain the tungsten powder of all size through the reduction of hydrogen in boiler tube like this.
The raw material that relates in the carbide alloy field is common has tungsten powder, oxidation tungsten powder, tungsten carbide powder.
Tungsten powder can obtain the tungsten powder of more tiny particle through the processing of ball mill.
The oxidation tungsten powder can obtain the oxidation tungsten powder of more tiny particle through the processing of ball mill.
Tungsten carbide powder can obtain the tungsten carbide powder of more tiny particle through the processing of ball mill.
The ultrafine gain size liner plate is arranged in the ball mill wall body, and tungsten powder, oxidation tungsten powder, tungsten carbide powder are difficult to the ultrafine gain size liner plate is caused damage.
If select the ball mill that has the ultrafine gain size liner plate for use, the oxidation tungsten powder is difficult to the ultrafine gain size liner plate is formed destruction.The ultrafine gain size liner plate can fine protection ball mill, avoids impurity to get in high-purity oxidation tungsten powder simultaneously and pollutes.
And ball mill can be broken for thinner particle with thicker oxidation tungsten powder.
And ball mill can be broken for thicker high-purity oxidation tungsten powder thinner high pure and ultra-fine oxidation tungsten powder.
If select for use high pure and ultra-fine oxidation tungsten powder that the ball mill preliminary treatment that has the ultrafine gain size liner plate obtains as raw material.The reduction of high pure and ultra-fine oxidation tungsten powder hydrogenation gas is handled through the tungsten powder reduction apparatus of the utility model and is cooperated corresponding technical process, just can obtain the high pure and ultra-fine tungsten powder.
