Description
Technical Field
The utility model relates to the technical field of liquid level indicating elements, in particular to a magnetic float level meter without blocking.
Background
The steel is a section bar with high strength, good rigidity and strong deformation resistance, can bear power load well, and is widely used in the individual building industry. In order to improve the performance of the steel and improve the toughness and strength of the steel, a rolling process is required to be carried out on the steel, oxide scales appear on the surface of the steel during rolling, and the method of removing the oxide scales on the surface of the steel is called descaling; the hot rolling production line of steelworks is usually matched with a high-pressure water descaling system, a plurality of descaling points are arranged on the production line to perform high-pressure descaling on the surfaces of steel, and because the production line is long, when a plurality of steel materials circulate on the production line in sequence, the condition that a plurality of descaling points use water simultaneously probably occurs, the water consumption requirement is increased at this time, if a water pump is used for directly supplying water to the descaling points, a water pump with very large flow is required, the matched capacity of the whole system can be increased, and the cost of the descaling system is increased. Therefore, the descaling system is designed with an accumulator, when no steel circulates on the production line where the descaling point is located, high-pressure water is stored in the accumulator, and when the descaling is needed, the accumulator supplies water to the descaling point of the rolling line or simultaneously supplies water to the accumulator and the descaling pump, so that the pressure of the descaling system is reduced, and the descaling effect of the steel is ensured.

The magnetic float liquid level meter needs to be communicated with the energy accumulator, floats in the guide cylinder of the liquid level meter have magnetism, and as high-pressure descaling water in the energy accumulator is turbid circulating water, the turbid circulating water is water cooled by spraying outside rolling line equipment and subjected to high-pressure water descaling, a large amount of iron oxide scales are contained in the turbid circulating water, the turbid circulating water is filtered before entering the energy accumulator, and the large iron oxide scales are removed, but small iron oxide powder is remained. After turbid circulating water enters the liquid level meter, the magnetic floater adsorbs ferric oxide powder in the turbid circulating water on the outer surface of the floater, when the floater adsorbs the ferric oxide powder to a certain degree, the diameter of the floater becomes large, so that the phenomenon that the floater is blocked in the guide cylinder is caused, the floater cannot move up and down along with the liquid level in the guide cylinder of the liquid level meter, the water level cannot be accurately displayed, and the problem that the water supplement of the energy accumulator system is excessive or insufficient is caused; once the blocking phenomenon occurs, the floater needs to be cleaned, the cleaning time is generally 1-2 weeks, and the time is long; the magnetic floater can magnetize the guide cylinder after being used in the guide cylinder for a long time, so that the guide cylinder can absorb ferric oxide powder, the cleaning of the guide cylinder can be more time-consuming, and the production progress is seriously influenced; there is therefore a great need in the market for a magnetic float level gauge that avoids jamming of the float.
