The invention discloses a high-temperature solution liquid level detection and control device, which is composed of a detection electrode assembly, a liquid level detector, a PLC control system, a stepping driver and a frequency converter for a feeding machine. instrument, stepper driver and feeder inverter are electrically connected, and the detection electrode assembly is electrically connected to the liquid level detector and the stepper driver respectively. The beneficial effect of the present invention is that it can accurately detect the liquid level of high-temperature liquid in basalt or other furnaces And control the speed of raw material feeding according to the liquid level value at any time so as to maintain the stability of the liquid level, so as to make the operation stable, increase the product output and reduce the scrap rate.
Description
technical field [0001] The invention relates to the technical field of liquid level measurement, in particular to a high temperature solution liquid level detection and control device. Background technique [0002] Basalt continuous fiber is a continuous fiber made of basalt ore as raw material, melted at 1450°C-1500°C, and drawn at high speed through a platinum-rhodium alloy wire drawing bushing. High / low temperature resistance, acid and alkali resistance, oxidation resistance, radiation resistance, heat and sound insulation, fire and flame retardant and other excellent properties, therefore, basalt fiber can be widely used in fire protection, environmental protection, aerospace, military industry, automobile and ship manufacturing, engineering plastics and construction and other fields. [0003] The production of basalt fiber is a continuous operation process of melting and wire drawing. The basalt ore raw material used for production needs to be replenished at any time i...
