[0002] In the overflow method substrate glass production line, the liquid level is one of the key control factors of the pool furnace channel, which is of great significance for extending the life of the production line and stabilizing the glass yield. The fluctuation of the glass liquid level will not only aggravate the erosion of the pool wall bricks and shorten the service life of the pool furnace; it will also produce refractory stones and reduce the glass yield; it will also cause the lead-out volume to fluctuate, affecting the molding operation.

[0003] At present, the types of liquid level gauges used in the glass industry mainly include: image liquid level gauge, laser liquid level gauge, nuclear liquid level gauge and platinum probe liquid level gauge. Among them, platinum probe liquid level gauge is widely used in overflow process production lines because of its simple principle, convenient installation and debugging, reliable function, safety and environmental protection.

[0004] In the prior art, the measuring point of the platinum probe liquid level gauge is set at the entrance of the channel cooling section, and the measuring accuracy can reach ±0.5mm. However, most of the liquid level gauge brackets are general ordinary brackets, which are not optimized for the structure of the platinum probe liquid level gauge. The supporting function is not reliable enough to ensure high installation and measurement accuracy. At the same time, it is difficult to adjust later, which is not convenient for operation and use.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the relevant technical solutions. Obviously, the described embodiments are only part of the embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] like Figure 1 As shown, the liquid level gauge support device for overflow method substrate glass production disclosed in this embodiment includes a base 1, an adjusting screw 2, a bottom plate 3, a steel frame 4, a top plate 5 and a liquid level gauge actuator 6.

[0018] The base 1 is a steel plate, which is embedded and fixed on the floor slab. The flatness needs to be controlled during the installation process.

[0019] In another embodiment, the base can be anchored by expansion bolts; if the floor is a steel platform, the base can also be fixed by welding.

[0020] The bottoms of four vertically upward adjusting screws 2 are welded to the base, and the upper ends of the adjusting screws pass through the horizontal oblong holes at the four corners of the bottom plate 3. Two nuts are provided on the adjusting screws to clamp the bottom plate up and down. The adjusting screws and the nuts on them provide support, clamping, limiting and fixing for the bottom plate.

[0021] The height and levelness of the bottom plate can be adjusted by adjusting the height of the nut. The horizontal position of the bottom plate can be adjusted through the oblong hole.

[0022] The steel frame 4 is made of stainless steel rectangular tubes, four rectangular long tubes are vertically located at the four corners, and short tubes are welded between adjacent rectangular long tubes for positioning. The bottom of the steel frame is welded to the bottom plate 3, and the bottom plate is ensured to be perpendicular to the rectangular long tubes during welding. A reinforcing tube is welded between the steel frame and the bottom plate to strengthen the structure of the steel frame.

[0023] The top plate 5 is welded to the top of the steel frame 4, and during welding, it is ensured that the top plate is perpendicular to the rectangular long tube of the steel frame 4. Four longitudinal oblong holes are formed on the top plate.

[0024] There are four lugs on the liquid level gauge actuator 6, and four bolt groups limit each lug in each longitudinal oblong hole. By adjusting the position of the lug in the longitudinal oblong hole, the longitudinal relative position of the liquid level gauge actuator can be adjusted.

[0025] The three-dimensional spatial position of the liquid level gauge actuator in the horizontal, vertical and height directions can be adjusted through the combination of the horizontal oblong hole, the vertical oblong hole and the adjusting screw rod.

[0026] In this embodiment, the thickness of the base 1 is 15mm, the specification of the adjusting screw 2 and the nut thereon is M24, the thickness of the bottom plate 3 is 20mm, the specification of the rectangular tube in the steel frame 4 is 50mm*50mm, the thickness of the top plate 5 is 10mm, and the material of each component is SUS304; the aperture of the four horizontal oblong holes on the bottom plate is 26mm, and the length is 120mm; the aperture of the four longitudinal oblong holes on the top plate is 12mm, and the length is 100mm.

[0027] like Figure 2 As shown, when the bracket supports the liquid level gauge actuator 6, the liquid level gauge actuator drives the liquid level gauge connecting rod 7 to perform periodic reciprocating lifting and lowering motions, and collects the potential signal between the liquid level gauge probe 8 and the glass liquid and feeds back to the touch screen control system.

[0028] One end of the liquid level gauge connecting rod 7 is connected to the lifting rod of the liquid level gauge actuator 6 through a special snap-on set, and the connecting rod performs periodic reciprocating lifting and lowering motion together with the lifting rod of the actuator; the other end is connected to the platinum probe through a stainless steel nut pipe joint. The liquid level gauge connecting rod is a stainless steel tube, and the potential signal line is built into the tube and filled and fixed with refractory filler.

[0029] The liquid level gauge probe is a platinum probe, which passes through the circular hole of the liquid level cover plate 9 and performs periodic reciprocating lifting and lowering motion with the connecting rod. The distance between the end of the probe and the glass liquid level in the liquid level tube 10 also changes accordingly, thereby causing the potential between the two to change. The potential signal line transmits the collected potential signal to the control system for processing.

[0030] The advantages of using this bracket are: the bracket's support for the probe liquid level gauge is stable and reliable; the bottom plate has a leveling function to ensure installation accuracy; it also has three-dimensional positioning adjustment functions in the up and down, left and right, and front and back directions, which is convenient for adjustment during installation and operation.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although detailed descriptions are made with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
