Description
Technical field
The present invention relates to ature of coal molding tool technical field, more particularly to a kind of grey prod cast tool.
Background technology
In ature of coal, ash fusibility is one of index of coal analysis.Ash fusibility refers to coal ash under the high temperature conditions
Temperature characterisitic when softening, melting, flowing, is the important performance indexes of steam coal and coal for gasification.Usual coal ash melting property
It is measured using pyramid method, i.e., gelatinized corn starch will be added in coal ash, the ash cone of triangular pyramid shape is made, the ring of high-temperature is put into
Border, is heated under certain atmosphere, the deformation of the ash cone in heating process is observed, with this determination coal ash melting property.
The meltbility of coal ash is a kind of critically important physical property, is directly connected to the sintering order of severity of boiler of power plant.
Safe handling influence on boiler, cement in vertical kiln etc. is very big, therefore just seems very necessary to the test of ash fusibility.It is existing
The test of ash fusibility is carried out by ash melting tester, ash cone is placed on supporting plate during test, in boiler tube flat-temperature zone
Uniform heating, while the gas medium of certain atmosphere is passed through, until ash cone sample reaches molten condition.In the process, camera
Continual shooting is carried out to the metamorphosis in ash cone sample thermal histories, the temperature of four characteristic points is drawn by analysis.
Therefore in order to ensure precision of analysis, the quality of ash cone sample is particularly important.
Traditional ash cone, typically all Rhizoma Sparganii cone.The manufacturing process of ash cone is comparatively laborious.Coal ash is placed on porcelain plate first
Or on glass plate, soaked with dextrin solution and be tuned into plastic shape, then shovel extrusion forming in ash charge prod cast with stylet.Use small point
Ash cone in mould is carefully pushed on porcelain plate or glass plate by knife, drying for standby..The existing mould for making ash cone is because structure is set
Meter is unreasonable, can only once make an ash cone, therefore ash cone producing efficiency is not high.Even if multiple ash cones can be made simultaneously,
Stress is small during due to being suppressed with stylet, and ash cone compresses low degree, is not easy to demoulding, and causing ash to be bored, demoulding is inconvenient, and ash cone exists
Damage is easily caused during demoulding.
The content of the invention
In view of this, it is an object of the invention to overcome the deficiencies of the prior art and provide a kind of ash cone producing efficiency is high, de-
Readily grey prod cast has film.
In order to solve the above-mentioned technical problem, the present invention is realized using following scheme：
A kind of grey prod cast tool, including the ash cone ware provided with multiple ash cone cavity volumes and the depression bar assembly for suppressing ash cone, it is described
The preceding ash that ash cone ware includes being detachably connected bores ware and rear ash cone ware, and the preceding ash cone ware is provided with the first local grey cone cavity volume, institute
Ash cone ware is provided with the second local ash cone cavity volume after stating, and the described first local ash cone cavity volume and the second local ash cone cavity volume can be with respect to groups
Close and form ash cone cavity volume.
In the application, the problem of ash cone producing efficiency is not high is solved by setting multiple ash cone cavity volumes in ash cone ware.
Ash cone ware and rear ash cone ware before by the way that ash cone ware is arranged to, when current ash cone ware and rear ash cone ware are connected together against, the
One local ash cone cavity volume and the second local ash cone cavity volume relative combinations form ash cone cavity volume.Multiple ashes are provided with traditional ash cone ware
When boring cavity volume, relative to single ash cone cavity volume, demoulding can become difficult.Since it is desired that ensureing the intact nothing of ash cone of each
Damage, this is greatly increased equivalent to demoulding variable, control difficulty is improved.Demoulding can not be completed well even with device for removing scum

Ash cone is caused to produce damage in demoulding, it is simple in construction, it is easy to operate.Ash cone is usually Rhizoma Sparganii centrum, is operated for the ease of demoulding,
Avoid due to the asymmetric damage for causing ash to bore of mould during demoulding, the triangular pyramid that the first ash cone cavity volume is 1/2nd
Body, the second ash cone cavity volume is also 1/2nd Rhizoma Sparganii cone.
Realize and be detachably connected with rear ash cone ware for the ease of preceding ash cone ware, the sidepiece of the preceding ash cone ware and rear grey cone ware
Sidepiece be respectively equipped with corresponding screw so that both can by threaded fastener realize be detachably connected.Threaded fastener bag
Include but be not limited to screw, screw, bolt etc..During compacting ash cone, it is ensured that preceding ash cone ware and rear ash cone ware will not be sent out
Raw relative displacement, prevents that the ash cone of compacting from deforming.The application is connected by using threaded fastener so that it is preceding ash cone ware and
Ash cone ware is firmly fixed together afterwards.In addition, after the completion of compacting, during boring ware by preceding ash and ash cone ware separated afterwards,
It is to realize both separation by turning on threaded fastener, can reach and slowly turn on during the turning on of threaded fastener, progressively
The process of decompression.Due to be fastened by threaded fastener, that at least needs threaded fastener at two, is turning on threaded fastener
During, by progressively being decompressed to different threaded fasteners respectively, final different threaded fastener is almost simultaneously
Turn on so that forward and backward ash cone ware is separated rather than the unilateral integrality for separating, ash cone being effectively ensured simultaneously, prevents one side
The damage of ash cone in the case of separating.
The pressing process of ash cone needs the compacting of pressured bar assembly to realize, for the compacting for depression bar assembly of being more convenient for, institute
Stating grey prod cast tool also includes being arranged on the ash cone gland being detachably connected with ash cone ware at the top of ash cone ware, and the ash cone gland is set
Have corresponding with ash cone cavity volume and run through the ash port that ash bores gland.Pass through the setting of ash cone gland, the ash cone of ash cone gland
Guiding is played a part of in up and down compacting of the mouth to depression bar assembly, easily facilitates the compacting of depression bar assembly.Furthermore, depression bar assembly is upper
