Description
Technical field
The utility model relates to a kind of stirring drivings 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 stirring driving of graphite heat preservation sand, background is efficiently solved
The problem of being pointed out in technology.
The technical solution adopted in the utility model is:
A kind of stirring driving of graphite heat preservation sand, including cross bar, the both ends lower section of the cross bar are fixed with a pair of and cross bar

Bar, the pulley are driven by pulley motor, and the vertical bar is equipped with a stirring axis in the other end relative to cross bar, described to turn over
Expect that the both ends of axis are linked with two vertical bar rotations respectively, has been axially fixed multiple stirrings in the outside cambered surface of the stirring axis
Bar is fixed with a driven gear coaxial with stirring axis in the middle part cambered surface of the stirring axis, is provided with below the cross bar
One driving gear to match with driven gear, the driving gear are rotated by chain-driving driven gear, the master
Moving gear is driven by gear motor, and the gear motor is fixed on the lower section of cross bar.
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 the movement in horizontal direction is realized by pulley and pulley.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
Below by specific embodiment and in conjunction with attached drawing, the utility model is further described in detail.
A kind of stirring driving of graphite heat preservation sand as shown in Figure 1, including cross bar 1, the both ends lower section of the cross bar 1 are fixed
There is a pair of and orthogonal vertical bar 2 of cross bar 1, the bottom of the vertical bar 2 is equipped with a pair of of pulley 8, and the lower section of the pulley 8 is equipped with
The slide bar 9 to match with pulley 8, the pulley 8 are driven by pulley motor, and the vertical bar 2 is relative to the another of cross bar 1
End is equipped with a stirring axis 3, and the both ends of the stirring axis 3 are linked with two rotations of vertical bar 2 respectively, the lateral arcs of the stirring axis 3
Multiple stirring bars 4 have been axially fixed on face, be fixed in the middle part cambered surface of the stirring axis 3 one with stirring axis 3 it is coaxial from
Moving gear 5, the lower section of the cross bar 1 are provided with a driving gear 6 to match with driven gear 5, and the driving gear 6 is logical
The rotation of chain-driving driven gear 5 is crossed, the driving gear 6 is driven by gear motor 7, and the gear motor 7 is fixed
In the lower section of cross bar 1.
The both ends of the stirring axis 3 pass through bearing and connect with vertical bar 2, and the inner ring and stirring axis 3 of the bearing are fixed, institute
Outer ring and the vertical bar 2 for stating bearing are fixed.
When the utility model is used, gear motor 7 starts, driven gear 5 is driven to rotate by driving gear 6, stirring
Axis 3 and driven gear 5 rotate synchronously, at this point, the stirring bar 4 being fixed in 3 cambered surface of stirring axis just will do it stirring, in stirring
When, start pulley motor, pulley 8 is enabled to slide on slide bar 9, realizes the movement in horizontal direction, the utility model knot
Structure is simple, practical and convenient, high-efficient, and the service life is long, is not likely to produce failure.
