Abstract
The utility model relates to a heat treatment device, more specifically a rotating heat treatment furnace which is used for gas-solid reaction and heat treatment of granular materials, such as hydrogen treatment of permanent magnetic rare earth materials, nitridation of neodymium, iron and nitrogen, preparation of anisotropic powders of the neodymium, he iron and boron, etc. In order to solve the problems of aggravated operating environment, complicated operation and relatively great space usage, etc. caused by that the existing rotating heat treatment furnace adopts an electrical heating furnace structure which can be opened and closed, the utility model discloses. The rotating heat treatment furnace comprises a rotating internal furnace which is supported on a support member and an electric heating furnace which is positioned on the outer layer of the internal furnace. The electric heating furnace is provided with at least one air input hole and one air output hole. The utility model changes a cooling structure and a cooling mode of the internal furnace of the rotating heat treatment furnace, decreases deterioration of the operating environment caused by cooling the internal furnace, simplifies operation of the heat treatment furnace and also decreases space usage of the heat treatment furnace which is used.
Description
Technical field
The utility model relates to thermal treatment unit, be specially a kind of rotary heat treatment furnace, be mainly used in the thermal treatment of gas-solid reaction and particulate species material, handle (HD) as the hydrogen of rare earth permanent-magnetic material, the nitriding of neodymium iron nitrogen, the preparation of neodymium iron boron anisotropic powder (HDDR) etc.
Background technology
Existing rotary heat treatment furnace, as the rotary hydrogen crushing furnace that is used for the rare earth alloy fragmentation comprises the rotatable flue of two end supports on strut member, is positioned at the outer field electrical heater of flue, flue rotary drive mechanism and is used for vacuum extractor, air distributing device that flue is vacuumized, inflates, and an end of flue communicates with vacuum extractor and air distributing device sealing.During use, the material that need handle is added in the flue from an end of flue, is positioned at the outer field electrical heater of flue flue is implemented heating, and simultaneously, vacuum extractor and air distributing device are to implementing to vacuumize and import corresponding gas in flue in the flue.But the electrical heater of existing heat treatment furnace is the left and right body of heater by opening and closing to be constituted.When needing flue cooling, cooling before discharging, body of heater is opened, flue is cooled off, or sprays water coolant to quicken the cooling of flue on flue.Like this, when flue cooled off, the heat radiation of high temperature flue was with degradation manipulation environment, if spray water coolant again, the steam of generation is degradation manipulation environment more; And water coolant has the chilling effect to flue, will reduce the life-span of flue.Simultaneously, but the furnace binding of opening and closing complicated operation not only, and also the body of heater of opening takies bigger space.
Summary of the invention
But the utility model owing to adopt the degradation manipulation environment that the electrical heater body structure brought, the complicated operation of opening and closing, the problem such as bigger that takes up room, provides a kind of improved, improved rotary heat treatment furnace of electrical heater furnace binding especially in order to solve existing rotary heat treatment furnace.
The utility model is to adopt following technical scheme to realize: rotary heat treatment furnace, and comprise the rotatable flue that is supported on the strut member, be positioned at the outer field electrical heater of flue, on electrical heater, have an empty gas entering opening and air at least and portal.Like this, when before discharging, needing, from empty gas entering opening input cooling air (as adopting blower fan), after cooling air and the flue surface thermal exchange to empty gas entering opening gas transmission to flue cooling, cooling, from the air discharge of portalling, thereby realize cooling, cooling before the flue discharging.Air is decided according to the size of electrical heater into and out of the selection of hole number.When electrical heater size (particularly length dimension) is big, can establish a plurality of air into and out of the hole.Air increases flue refrigerative homogeneity into and out of Kong Duoke.
The utility model has improved the structure of the electrical heater of rotary heat treatment furnace, by air is set into and out of the hole on electrical heater, has changed the flue cooling structure and the type of cooling (air cooling) of rotary heat treatment furnace; But overcome defective that electrical heater brought and deficiency that existing rotary heat treatment furnace adopts the opening and closing structure, to the deterioration of operating environment, simplified the operation of heat treatment furnace when having reduced the flue cooling, occupation space when also having reduced the heat treatment furnace use.
Description of drawings
Fig. 1 is the structural representation of rotary heat treatment furnace described in the utility model;
Embodiment
Rotary heat treatment furnace comprises the rotatable flue 2 that is supported on the strut member 1, is positioned at the outer field electrical heater 3 of flue, has an empty gas entering opening 4 and air at least and portal 5 on electrical heater.
Empty gas entering opening 4 is opened in the bottom of electrical heater 3, air 5 tops of opening at electrical heater 3 of portalling.Because warm air is the mobile that makes progress, can increase the convection of air circulation in the electrical heater, help improving the cooling performance of flue.
This rotary heat treatment furnace also is provided with known air cooling apparatus 10.The cooling air of input fully cools off through air cooling apparatus, imports in the electrical heater again, can further improve cooling performance, the speed of cooling of flue.Produce the source with blower fan 11 as cooling air, blower fan is dried in air cooling apparatus, and the air-out of air cooling apparatus is sent in the electrical heater through empty gas entering opening.
The same with existing rotary heat treatment furnace, rotary heat treatment furnace described in the utility model also disposes vacuum extractor, the air distributing device that is used for vacuumizing in the flue, inflating.Need the end adding of the furnace charge of processing from flue, the flue rotary drive mechanism drives the flue rotation, and simultaneously, electrical heater heats flue.Dispose, blower fan is carried cooling air before the discharging in electrical heater, makes flue be able to quick cooling.
Claims (4)
