Abstract
The utility model discloses an inlay core graphite bull stick that dusts, it by the graphite bull stick and not heat conducting material's the core sleeve pipe of inlaying constitute, open in the graphite bull stick and inlay the core through -hole, inlay the core sleeve pipe including head pipe, in a plurality of pipe and bottom tube, the head pipe, in a plurality of pipe and bottom tube in order the suit inlay the intraductal through -hole of carrying concise agent that is equipped with of core cover in inlaying the core through -hole, be equipped with the graphite screw between graphite bull stick and the bottom tube. The utility model discloses an inlaying the core sleeve pipe and combining the graphite bull stick, very big degree has reduced phenomenon and frequency that the degassing apparatus use emergence of dusting is dusted and is blockked up, especially more can show its superiority to the concise agent that the jet particle is thinner.
Description
Technical field
The utility model relates to a kind of graphite bull stick for the degassing apparatus that dusts in aluminum casting industry, and specifically a kind of edge core dusts graphite bull stick.
Background technology
In aluminum casting industry, be connected after usually connecting graphite runner with graphite bull stick with the main shaft of the degassing apparatus that dusts, the refining agent in pulvis tank body imports molten aluminum liquid by the inert gas regulating pressure and flow in advance by there being the graphite bull stick of through hole.Refining agent uniformly dispersing, in molten aluminum liquid, is taken liquid level out of after the impurity in aluminium liquid is mingled with, is finally reached the object of refinery molten aluminium.
The dust graphite bull stick of degassing apparatus of tradition directly utilizes degasification pipeline to replace dusting pipeline, and the pipeline that dusts often is blocked by refining agent, and chief reason is:
1, when graphite bull stick transmits refining agent by through hole, the heat of aluminium liquid makes the temperature of refining agent raise rapidly by the tube wall of graphite bull stick, and part refining agent just starts thawing of being heated before arrival via bottoms.
2, the be heated refining agent melted and the normal refining agent transmitted is bonded together, and very easily causes pipeline blockage of dusting.
Utility model content
Technical problem to be solved in the utility model be to provide a kind of have shaping simply, not easily blocking, long service life, maintenance is dusted and degassing efficiency is stable edge core dust graphite bull stick, this graphite bull stick had both met degasification requirement, also met requirement of dusting.
The utility model solves the problems of the technologies described above with following technical scheme:
The utility model edge core dusts graphite bull stick, it is made up of the edge core sleeve of graphite bull stick and not heat-conducting, edge core through hole is had in described graphite bull stick, described edge core sleeve comprises head tube, some middle pipes and bottom tube, head tube, some middle pipes and bottom tube are sleeved in edge core through hole in order, are provided with the through hole of conveying refining agent in edge core sleeve.
Graphite screws is equipped with between described graphite bull stick and bottom tube.
The utility model adopts edge core sleeve in conjunction with graphite bull stick, high degree reduce degassing apparatus use procedure of dusting dust blocking phenomenon and frequency, especially thinner to jet particle refining agent, more can show its superiority, and there is shaping simple, long service life, maintenance is dusted and degassing efficiency is stable advantage.

Detailed description of the invention
Below in conjunction with accompanying drawing, the technical solution of the utility model is explained as follows:
The utility model edge core dusts graphite bull stick, and it is made up of graphite bull stick 1 and edge core sleeve, is processed with edge core through hole, as shown in Figure 1 in graphite bull stick 1.Edge core sleeve comprises head tube 2 (shown in Fig. 2-1), middle pipe 3 (shown in Fig. 2-2) and bottom tube 4 (shown in Fig. 2-3), edge core sleeve by calcium silicates material etc. not heat-conducting make, the head tube of edge core sleeve, some middle pipes and bottom tube are sleeved in edge core through hole in order, are provided with the through hole of conveying refining agent in edge core sleeve.Be assemblied in the edge core through hole of graphite bull stick 1, edge core sleeve in be provided with conveying refining agent through hole, the edge core assembled dust graphite bull stick structure as shown in Figure 4, be equipped with graphite screws 5 between graphite bull stick 1 and bottom tube 4.
The utility model edge core dusts the work flow of graphite bull stick, specifically comprises following operating procedure:
1, rough turn graphite bull stick cylindrical
By degassing apparatus designing requirement of dusting, get the graphite bars blank material of the good appropriate length of anti-oxidant treatment and diameter, the rough turn graphite bars cylindrical of upper lathe.
2, graphite bull stick boring
Lathe on the graphite bull stick of rough turn good cylindrical bored respectively bottom outlet 7 at its two ends and drawn hole 9, bottom outlet 7, for assembling graphite screws 5, drawing hole 9 for carrying just from the degassing apparatus refining agent out that dusts, drawing the good chamfering 8 of end car in hole.Clamping drill gun, has bored edge core through hole by graphite bull stick.
3, the position that is connected with graphite runner and the degassing apparatus main shaft that dusts of finish turning graphite bull stick.
4, the edge core sleeve of not heat-conducting is processed
Upper lathe process edge core sleeve, edge core sleeve adopts calcium silicates material, and every root graphite bull stick manufactures in a section header pipe, a joint bottom tube and some joints and manages, and the cylindrical step of bottom tube and graphite screws manufacture, and head tube is provided with and the conehead drawing bore end and mate.
5, processing graphite screw, graphite screws is completion of processing before processing graphite bull stick.
6, in order head tube, middle pipe and bottom tube are respectively charged in the edge core through hole of graphite bull stick, concrete operations are:
(1) the Hole chamfering place of drawing of corresponding for the conehead of head tube graphite bull stick is put into edge core through hole;
(2) upper ceramic fiber paper is padded after the other end of head tube being filled white glue with vinyl;
(3) ceramic fiber paper another side is glued white glue with vinyl, put into a joint and manage;
(4) then the other end of middle pipe is filled white glue with vinyl, ceramic fiber paper on pad, then put into a joint and manage, so operation is until end only leaves the position of assembling bottom tube;
(5) finally load bottom tube, between bottom tube and bottom outlet, assemble graphite screws;
7, baking 3 hours in the electric furnace finally the graphite bull stick assembled being put into 300 DEG C, when in-furnace temperature drops to 50-70 DEG C takes out graphite bull stick, carries out packing.
If edge core sleeve processes through hole before assembly, complete rear car planar end surface and graphite bull stick end face in assembling.
If edge core sleeve is also do not process through hole before assembly, unified with drill gun boring after assembling, car planar end surface again after having holed.
The utility model edge core graphite bull stick that dusts dusts graphite bull stick comparing in production technology and result of use, in table 1 with common.
