Description
Technical Field
The utility model belongs to high temperature furnace production field relates to a high temperature crucible feeding device.
Background
The crucibles used in the development experiments of the silicate glass frit prescription at present mainly comprise common ceramic crucibles, corundum crucibles, graphite crucibles, platinum crucibles and the like. Wherein, the ceramic crucible has low price but can only be used under the condition of medium and low temperature, such as less than about 1450 ℃, and can crack after being used for a long time; the corundum crucible can be melted at high temperature, and the bearing temperature is improved by about 200 ℃ compared with that of a ceramic crucible; for glass melting work, a ceramic crucible or a corundum crucible is very easy to be co-melted with glass, a sample is not easy to take out, and the service life of the crucible is generally only once; although the graphite crucible does not react with the glass basically, the glass melting is mostly an oxidizing atmosphere, the graphite crucible needs to be introduced with a protective atmosphere, and the carbon component in the crucible is melted into the glass after long-time melting, so that the transparency of the glass is affected. Compared with the first three types of crucibles, the platinum crucible is widely used due to the characteristics of high melting point, smooth surface, uniform wall thickness, easy control of temperature field, long service life and the like. However, the platinum has high thermal conductivity and rapid temperature reduction, so that the viscosity of the molten glass at high temperature is high during discharging, and the discharging difficulty is increased; and the platinum is soft and easy to deform and expensive, and the direct clamping of the platinum pot easily causes the deformation of the platinum pot, thereby affecting the service life. Therefore, in order to solve the above problems when the platinum crucible is used for melting glass, a bushing is usually added outside the platinum crucible, so that the function of heat preservation is achieved, and the platinum crucible is protected.
The conventional mullite lining is low in heat conductivity and poor in thermal shock resistance, so that the platinum crucible with the lining is slow in heating rate and incapable of being rapidly cooled compared with a platinum crucible. In order to improve the experimental efficiency, a platinum pot is usually required to keep high-temperature continuous operation, and high-temperature powder addition is inevitably required. The traditional feeding mode of the medicine spoon needs a plurality of times of operation time, the long-time temperature difference easily causes the cracking of the lining, further influences the service life of the lining, and people are close to a heat source, and easily cause the discomfort of human bodies and scald.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome above-mentioned prior art's shortcoming, provide a high temperature crucible feeding device, avoid the inside high-temperature gas of crucible to contact the outside air to make the people keep away from the heat source, improved the safety index.
In order to achieve the above purpose, the utility model adopts the following technical scheme to realize:
a high-temperature crucible feeding device comprises a material storage tank and a hollow pipe which are sequentially arranged from top to bottom;
the storage tank is the back taper, and the top is provided with the top cap, and storage tank bottom and hollow tube intercommunication are provided with the ball valve on the hollow tube, and the hollow tube bottom is provided with fixed stop.
Preferably, the fixed baffle is located the hollow tube and is close to the bottom position, and the hollow tube bottom is the screw thread end, and the screw thread end is connected with the nut, is provided with adjustable fender between fixed baffle and the nut.
Preferably, top cap one side is articulated with the storage tank top, and top cap opposite side and storage tank top lock joint.
Preferably, the storage tank is internally provided with capacity scales.
Preferably, the total length of the storage tank and the hollow pipe is 1-1.2 m.
Preferably, the hollow pipe, the storage tank and the top cover are all made of stainless steel.
Compared with the prior art, the utility model discloses following beneficial effect has:
the utility model discloses a set up the ball valve on the hollow tube, make the powder that adds drop to the crucible through the hollow tube from the storage tank, through the handle of adjusting the ball valve, control it and open and shut, and then the velocity of flow that the powder dropped to the crucible in the control storage tank shelters from the crucible top through the baffle, avoids reinforced in-process because the inside high temperature of crucible causes pounces on material and raise dust to make the people keep away from the heat source, improved the safety index.
Furthermore, by arranging the movable baffle, different movable baffles can be replaced according to the limitation of the size and the material of the crucible.
Furthermore, top cap one side is articulated with the storage tank, and the opposite side lock joint is conveniently opened, and the leakproofness has been guaranteed to the lock joint, prevents that the inside high-temperature gas of crucible from upwards spouting.
Furthermore, after each feeding, the adding amount of the powder can be known by observing the volume scale change of the powder, so that the adding amount can be accurately controlled.
