Abstract
The utility model discloses a powder metallurgy pulverizing device which comprises a heating box, a radiating tube and a powder storage tank sequentially connected from the top to the bottom. The powder metallurgy pulverizing device is characterized in that the heating box is hollow. The interior of the powder metallurgy pulverizing device comprises a crucible and an atomization pipe arranged on the lower portion of the crucible and communicating with the chamber thereof, wherein the atomization pipe communicates with the radiating tube, the tube wall of the radiating tube is hollow, and liquid coolant is arranged in the radiating tube. Metals melted in the crucible to become liquid metal, are atomized into metal particles through the atomization pipe, and are rapidly cured into solid particles through the radiating tube. The powder metallurgy pulverizing device has the advantages of high sphericility, controllable powder granularity, low oxygen content and low production cost and is suitable for production of various metal powders. The powder metallurgy pulverizing device overcomes the defects of the prior art.
Description
Technical field
The utility model relates to a kind of device of powder process that metallurgy is carried out with powder material, belongs to mechanical field.
Background technology
Powder metallurgy be produce metal or with metal dust (or mixture of metal dust and non-metal powder) as raw material, through being shaped and sintering, manufacture the technology of metal material, composite and all kinds goods.Powder metallurgic method has similar place to production pottery, and therefore, a series of New Technologies In Powder Metallu Rgies also can be used for the preparation of ceramic material.Due to the advantage of PM technique, it has become the key that solves new material problem, plays a part very important in the development of new material.
Powder process, is one of powder metallurgy master operation, and powder process is the process of powder that raw material is made.Conventional milling method is Mechanical Method, is to utilize ball milling or utilize power (as air-flow or liquid stream) to make to produce between metalliferous material fragment the method for collision, friction acquisition metal dust.But the major defect of this method is that product oxygen content is high, powder shape is difficult to control, too small in batches, is unfavorable for large-scale production.
Utility model content
It is low that the technical problems to be solved in the utility model is to provide a kind of oxygen content, and powder shape is regular, is convenient to the fuel pulverizing plant of large-scale production,
For addressing the above problem, the utility model provides a kind of powder metallurgy fuel pulverizing plant, comprise the heating cabinet, radiating tube and the powder storage tank that connect successively from top to bottom, it is characterized in that, described heating cabinet is hollow form, and inner include crucible and be arranged on the bottom of described crucible and the mist pipe being communicated with its cavity volume, described mist pipe is communicated with described radiating tube, the tube wall of described radiating tube is hollow shape, and inside is provided with cooling fluid.
As further improvement of the utility model, described radiating tube is communicated with the fluid box of a sealing by drain pipe and feed tube, is also connected with drawing liquid pump between described drain pipe and fluid box.
As further improvement of the utility model, the hollow shape that the tank wall of described heating cabinet is vacuum.
As further improvement of the utility model, on described heating cabinet, be also connected with the vavuum pump of described heating cabinet internal communication and add gas to add air pump to described heating cabinet inside.
As further improvement of the utility model, described cooling fluid is water.
As further improvement of the utility model, described in to add the gas that air pump adds be argon gas.
The beneficial effects of the utility model are, metal becomes metal liquid and is atomized into several metallic particles through mist pipe through melting in crucible, finally by radiating tube, is rapidly solidificated into solid particle.This mode has the advantages such as production that sphericity is high, powder size is controlled, oxygen content is low, production cost is low and adapt to various metals powder, has overcome deficiency of the prior art.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 2-vavuum pump; 4-adds air pump; 6-crucible; 8-heating cabinet; 10-mist pipe; 12-radiating tube; 16-powder storage tank; 18-feed tube; 20-fluid box; 22-drain pipe.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further details.
As shown in Figure 1, the utility model comprises heating cabinet 8, radiating tube 12 and the powder storage tank 16 connecting successively from top to bottom, heating cabinet 8 is hollow form, and inner include crucible 6 and be arranged on the bottom of crucible 6 and the mist pipe 10 being communicated with its cavity volume, mist pipe 10 is communicated with radiating tube 12, the tube wall of radiating tube 12 is hollow shape, and inside is provided with cooling fluid.
Metal becomes metal liquid and is atomized into several metallic particles through mist pipe 10 through melting in crucible 6, finally by radiating tube 12, is rapidly solidificated into solid particle and drops in powder storage tank 16.This mode has the advantages such as production that sphericity is high, powder size is controlled, oxygen content is low, production cost is low and adapt to various metals powder, has overcome deficiency of the prior art.
The tank wall of heating cabinet 8 is the hollow shape of vacuum.Can be heating cabinet 8 insulations.
On heating cabinet 8, be also connected with the vavuum pump 2 of heating cabinet 8 internal communication and add gas to add air pump 4 to heating cabinet 8 inside.Vavuum pump 2, for heating cabinet 8 is vacuumized, adds air pump 4 and is used to heating cabinet 8 that protective atmosphere is provided.
Cooling fluid is water.Draw materials conveniently, cost is low.
Adding the gas that air pump 4 adds is argon gas.Adopt in the enough separating atmospherics of argon gas activity gas to participate in reaction as oxygen etc., thereby play the pure property of protective reaction.
Above foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, related personnel can, within not departing from the scope of this utility model technological thought, carry out various change and modification completely.The technical scope of this utility model is not limited to the content on description, must determine technical scope according to claim scope.
