Description
Technical field:
This utility model relates to a kind of resistance-type silicasol case detection drying device, belongs to machinery
Technical field.
Background technology:
Investment casting shell quality directly affects dimensional accuracy and the surface quality of foundry goods, meanwhile,
The manufacturing cycle length of shell affects again the production cycle of foundry goods.Using Ludox as binding agent
The process that the moisture that shell shell process is really in coating constantly evaporates.Steaming along with moisture
Sending out, silica sol particle is the most close, has the frozen glue of molecular link and hydrogen bonded, between particle
Form the gel that Si-O-Si bond is closed, it is established that higher structural strength and hardness, can bear
High temperature, will not back dissolving, be that shell has good high-temperature behavior.But the mistake of silicasol case
The journey used time is longer and cannot determine the dry concrete time, so accurately grasping shell to be dried journey
Degree, drying time make great sense for producing.
Utility model content:
The technical problems to be solved in the utility model is to provide one can solve silicasol case
It is dried relatively slow under normal conditions and degree of drying cannot be determined and be completely dried the problems such as time.
This utility model uses thermal convection current mode to accelerate shell and is dried, and uses electric-resistivity method to be dried shell
Degree is monitored.
In order to solve the problem existing for background technology, this utility model is to use techniques below side
Case:
A kind of resistance-type silicasol case detection drying device, including heater, heating
Storehouse and resistance monitor, described heating cabinet side is connected with heater by wind conveying pipe,
Its opposite side is connected with resistance monitor；Described resistance monitor side is equipped with spiral conducting line A
With spiral conducting line B, described spiral conducting line A one end connects a table folder, described spiral conducting line B
One end connects an indicator；Described table folder and indicator may be contained within inside heating cabinet.
Further, described heater is by hot blast filter, electromagnetic heater, motor
Composition.
Further, described electromagnetic heater upper end connects air intake filter, and its lower end leads to
Crossing a blast pipe and a hot-air blower connects, described hot-air blower connects a driving motor.
Further, described blast pipe is by wind conveying pipe in a threeway and one and once wind conveying pipe
Connect.
Further, it is characterised in that described upper appendix is connected with heating cabinet top, institute
State lower wind conveying pipe to be connected with bottom heating cabinet.
Further, it is characterised in that be provided with one inside described heating cabinet molten for supporting silicon
The support of glue-type shell.
Further, described heating cabinet side is provided with an exhaustor, inside described exhaustor
It is provided with the exhaust fan of a quickening exhaust velocity.
When Ludox is dried, silicasol case is hung on the support in heating cabinet, by table
It is clipped on the outer surface of shell, test pencil is inserted the internal difficult cadre position of Ludox, starts heating
Device, carries out thermal convection current heating by upper and lower wind conveying pipe to the shell in heating cabinet, passes through resistance
Monitor moment monitoring resistor changes.The hot-air taking away moisture is discharged by exhaustor.Work as electricity
Resistance monitor recorded resistance variations when reaching marginal value, illustrates to be dried.
This utility model can solve silicasol case and be dried relatively slow and cannot under normal conditions
Determine degree of drying and be completely dried the problems such as time.
This utility model has the beneficial effect that simple in construction, good drying effect, monitoring convenience, work
Make efficiency high.
