Abstract
The utility model relates to a kind of resonance difference frequency glass furnace high temperature liquid level supervisory system, carries out electrical equipment be formed by connecting by resonant frequency driving mechanism, resonant frequency reliever, piezoelectric type intermediate frequency receptor, differential frequency circuit, feed driving circuit and six parts of motor for feeding.Resonant frequency driving mechanism is simultaneously for resonant frequency reliever and differential frequency circuit provide signal, the natural frequency that furnace chamber occurs feeds back to differential frequency circuit by piezoelectric type intermediate frequency receptor and carries out mixing, mixed frequency signal is after the selection of feed driving circuit, just feed frequency inverted is wherein become to the reinforced driving of motor for feeding, thereby realized kiln high temp glass liquid level noncontact monitoring, equipment used simple and durable, easily operation, accuracy is high.
Description
Technical field
The utility model relates to a kind of supervisory system of glass furnace high temp glass liquid level, especially can realize the noncontact effective monitoring to high temp glass liquid level by resonance difference frequency.
Background technology
Existing glass furnace tank level control has following several mode: 1, manually control, adopt artificial first omiting to survey, precision is very poor, and precision is in 5 millimeter; 2, pneumatic probe is controlled, and precision is in 1 millimeter, but pneumatic probe tube easily corrodes, and liquid level can progressively go up along with the erosion of exploring tube; 3, laser liquid level controller, precision is in 0.2 millimeter, and major defect is to need laser generator and receptor and laser tube life-span too short, more difficult to light when liquid level is adjusted; 4, by pick up camera, kiln high temperature mark brick is made a video recording continuously, shooting variable signal is transported to computer and carries out image processing, again process information is passed to charging system, the precision of this Untouched control can reach 0.2 millimeter, its major defect one is that mark brick is changed frequently, the 2nd, and resolving power is unstable.
Summary of the invention
In order to overcome the defect of existing glass furnace tank level control, the utility model provides a kind of resonance difference frequency glass furnace fluid level control system.
Realize the technical solution of the utility model: be exactly that " different spaces has different natural frequencies " this principle is changed into simple technique: native system carries out electrical equipment by resonant frequency driving mechanism, resonant frequency reliever, piezoelectric type intermediate frequency receptor, differential frequency circuit, feed driving circuit and six parts of motor for feeding and is formed by connecting.Its work relationship is: resonant frequency driving mechanism is simultaneously for resonant frequency reliever and differential frequency circuit provide frequency signal, the natural frequency that furnace chamber occurs feeds back to differential frequency circuit by piezoelectric type intermediate frequency receptor and carries out mixing, mixed frequency signal, after the selection of feed driving circuit, just becomes feed frequency inverted wherein the reinforced driving of motor for feeding.
The beneficial effects of the utility model: realize kiln high temp glass liquid level noncontact monitoring, equipment used simple and durable, easily operation, accuracy is high, and its precision can be in 0.1 millimeter of limit of error.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
In Fig. 1,1 is glass precursor solution; 2 is furnace chamber; 3 is resonant frequency reliever; 4 is resonant frequency driving mechanism; 5 is piezoelectric type intermediate frequency susceptor; 6 is differential frequency circuit; 7 is feed driving circuit; 8 is motor for feeding.
Embodiment
Below in conjunction with Fig. 1, performance of the present utility model is described.
In Fig. 1, resonant frequency driving mechanism (4) is simultaneously for resonant frequency reliever (3) and differential frequency circuit (6) provide signal, the natural frequency that furnace chamber (2) occurs feeds back to differential frequency circuit (6) by piezoelectric type intermediate frequency receptor (5) and carries out mixing, mixed frequency signal, after the selection of feed driving circuit (7), just becomes feed frequency inverted wherein the reinforced driving of motor for feeding (8).
