Description
Technical field
The utility model relates to a kind of novel stirring cooling devices of graphite heat preservation sand.
Background technique
Graphitizing furnace feeding temperature-raising is to after 2900 DEG C, and heating process is completed, into cooling stage.Isostatic pressing formed graphite product is raw
Produce the period in, heating process is generally 10~15 days, and cooling technique process, for avoid cooling down it is too fast cause damage of product, can
Up to 30 days or so.Heating process is limited by the production requirement of properties of product, and adjustment space is smaller, and cooling technique in addition to
Needed outside strict control in critical process point, process be it is more shorter better, there are biggish elastic adjustment spaces.
It is high to temperature requirement due to being graphitized during being graphitized feeding temperature-raising, using 0~1mm granularity point in furnace
The petroleum coke powder of cloth carries out efficient insulation effect to furnace body as heat preservation sand, prevents heat from largely conducting outward.But this layer is protected
The high-efficiency insulated effect of warm sand is the biggest obstacle of cooling technique, and therefore, the groundwork of cooling technique is exactly to remove heat preservation sand,
Reinforce furnace body thermal diffusion, shortens the cooling time of graphitizing furnace.
Currently, most of domestic graphitization workshop is directly caught heat preservation sand using grab bucket, it is placed in independent cold burden storehouse
It is cooling.The major advantage of the cooling means is: red heat heat preservation sand directly being caught, radiating rate is fast, and the cooling cycle is typically about
20 days.But there are shortcomings for this method: 1 material grasping process operating difficulties, it is difficult to which accurate control be easy to cause product to aoxidize；2 grab
Need to configure independent cold burden storehouse after material outside furnace；After 3 heat preservation sand are placed in external place, since heat preservation emery dust material granularity is distributed as
0~1mm, it is difficult to all recycle, form duration waste；4 material grasping processes need to drive a vehicle and personnel have cooperated on furnace body
At there are security risks.
Utility model content
In view of the above-mentioned problems, the utility model provides a kind of novel stirring cooling device of graphite heat preservation sand, effectively solve
The problem of being pointed out in background technique of having determined.
The technical solution adopted in the utility model is:
A kind of novel stirring cooling device of graphite heat preservation sand, including cross bar, the both ends lower section of the cross bar are fixed with one
To with the orthogonal vertical bar of cross bar, the vertical bar relative to cross bar the other end be equipped with a stirring axis, the stirring axis
Both ends are linked with two vertical bar rotations respectively, and multiple stirring bars have been axially fixed in the outside cambered surface of the stirring axis, described
A driven gear coaxial with stirring axis is fixed in the middle part cambered surface of stirring axis, be provided with below the cross bar one with it is driven
The driving gear that gear matches, the driving gear are rotated by chain-driving driven gear, and the driving gear is logical
Gear motor driving is crossed, the gear motor is fixed on the lower section of cross bar, and the stirring axis is the hollow structure of internal water storage,
The side cambered surface of the stirring axis is equipped with multiple with the fog-spray nozzle being connected inside stirring axis, and one end of the stirring axis passes through
Rotary joint is connected with water inlet pipe.
It is connect preferably, the both ends of the stirring axis pass through bearing with vertical bar, the inner ring and stirring axis of the bearing
Fixed, outer ring and the vertical bar of the bearing are fixed.
The utility model by stirring bar on stirring axis to heat preservation sand carry out it is lasting stir, to accelerate to keep the temperature sand
Rate of heat dispation realizes the purpose that graphite is quickly cooled down, and fog-spray nozzle is sprayed, and cooling effect can be greatly improved, and improves cooling
Rate.
