Description
Technical Field
The utility model belongs to the technical field of borosilicate glass pipe drawing forming technique and specifically relates to a full electric melting glass kiln furnace charge storehouse material layer thickness measuring device is related to.
Background
In the vertical deep electric smelting process of the all-electric smelting thick material layer for drawing borosilicate glass tubes, the thickness of the material cabin layer is an important process parameter, the normal thickness is about 100mm-200mm, the surface of a melting tank is covered with cold batch, the batch is heated under the covering layer, and the four stages from heating to glass forming are total:
1. the surface of the batch is 0-40mm, the temperature is stabilized at 120 ℃, and only water is evaporated, so that the batch can be called a cold batch layer;
2. the depth is 40-80mm, the temperature is increased from 120 ℃ to 250 ℃, and boric acid begins to decompose and is called a thermal matching material layer;
3. the temperature change is most severe when the depth is 80-110mm, and the temperature is raised from 250 ℃ to 1000 ℃, so that the reaction process of the borosilicate is completed, and the reaction process is called a borosilicate reaction zone;
4. the next layer of the borosilicate reaction zone is a molten glass containing a large number of bubbles and with unmelted sand particles, referred to as the molten layer of glass.
5. The lowest layer is the fining and homogenizing zone of the glass.
If the thick material layer is improperly operated, the material arch is easily formed due to the excessively thick material layer, the air bubbles are not easily discharged, the heat preservation effect cannot be realized due to the excessively thin material layer, the boron retrogradation phenomenon disappears, and stones and gas lines are easily generated.
Disclosure of Invention
An object of the utility model is to overcome the shortcoming that exists among the prior art, provide a measuring device of the reinforced bed of material thickness of full electric melting furnace during borosilicate glass production, this measuring device includes matched with fixed electrode and bayonet electrode, cooperates ampere meter numerical value to show and realize, and the technical scheme of adoption is: the utility model provides a full electric melting glass furnace charge storehouse stock layer thickness measuring device which characterized in that: the measuring device comprises a hand-operated transmission mechanism arranged on the side wall of the kiln, and the end part of the hand-operated transmission mechanism is connected with an inserted molybdenum electrode; the measuring device also comprises a fixed molybdenum electrode fixed in a kiln bin, and the fixed molybdenum electrode is connected with an ammeter.
The low voltage obtaining mode of the measuring device is as follows: the low voltage required by the measuring device is obtained by reducing the voltage of 380V alternating current through an isolation transformer.
The beneficial effects of the utility model reside in that: the device is convenient for measuring the thickness of the material layer, and can provide effective data in time so as to take effective measures to control the thickness of the material layer; the device has the advantages of simple structure, low cost and accurate and reliable measurement result, and is particularly beneficial to the stability of product quality.
Drawings
Fig. 1 is the structure schematic diagram of the present invention, and fig. 2 is the electrical schematic diagram of the present invention. The device comprises an all-electric melting glass kiln 1, a hand-operated transmission mechanism 2, a fixed molybdenum electrode 3, an inserted molybdenum electrode 4, a thick material layer 5, molten glass 6, a switch 7, a power controller 8, an isolation transformer 9 and an ammeter 10.
Detailed Description
The following describes embodiments of the present invention with reference to the drawings.
The utility model discloses a full electric melting glass kiln furnace charge storehouse bed thickness measuring device combines attached figure 1, and what this device mainly measured is glass liquid top, not melt or not yet the bed thickness of material of melting entirely.
The measuring device comprises a hand-operated transmission mechanism 2 arranged on the side wall of the kiln, wherein the hand-operated transmission mechanism 2 can drive an inserted molybdenum electrode 4 to ascend or descend, the end part of the hand-operated transmission mechanism 2 is connected with the inserted molybdenum electrode 4, the measuring device also comprises a fixed molybdenum electrode fixed in a kiln storage bin, the fixed molybdenum electrode is fixed at the position of molten glass 6 in advance, and the fixed molybdenum electrode 4 is connected with an ammeter 10.
Referring to fig. 2, the voltage system of the measuring device transmits industrial 380 v alternating current to the isolation transformer 9 through the power controller 8, and after the voltage is reduced to 20 v through the isolation transformer 9, the voltage is supplied to a measuring circuit formed by the fixed molybdenum electrode 3, the inserted molybdenum electrode 4 and the ammeter 10.
The using method comprises the following steps: adjusting the power controller 8 to make the secondary output voltage of the isolation transformer 9 reach 20V; the hand-operated transmission mechanism 2 is shaken, the inserted molybdenum electrode 4 is slowly inserted into the material layer until the ammeter 10 is observed to be changed violently (the reason of the phenomenon is that the molten glass shows different resistances at different temperatures, the conductivity of the molten glass is obviously enhanced along with the temperature rise, so that the numerical value of the ammeter is about 1A when the molten glass is just detected, and the numerical value can reach about 5A when the molten glass is contacted with the molten glass above 1000 ℃; and measuring the insertion depth of the inserted molybdenum electrode 4 to obtain the thickness of the material layer.
Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and the changes, modifications, additions or replacements made by those skilled in the art within the scope of the present invention also belong to the protection scope of the present invention.
