Description

Filtering grab bucket

Technical Field

The utility model relates to the technical field of metallurgical water treatment equipment, in particular to a filter type grab bucket.

Background

At present, in a turbid circulating water treatment system of a continuous casting machine, a cyclone well area is used for a grab bucket facility used for cleaning oxide skin, the opening and closing of an opening and closing mechanism are realized by the self weight of a sliding block (shown as a in figure 1) and the tensioning of a spring (shown as f in figure 1), when the sliding block a descends, the spring f is in a loose state, the spring is easily stirred into a rotating pulley (shown as c in figure 1) to cause the phenomena of breakage of the spring f or groove separation and rope extrusion of a steel wire rope, and the grab bucket cannot be normally used or has a rope breakage and falling accident; if the length of the spring a is too short, the spring a is easy to excessively stretch and lose elasticity in the use process.

In addition, in the operation process of the cyclone well, small impurities such as plastic, foam, wood blocks and the like which enter the cyclone well along with the flushing cinder water in a production field exist on the water surface in the well, and the impurities float on the water surface and are easily sucked into the water pump after a long time, so that the water quantity on the water pump is reduced or the pump body vibrates, and the water pump cannot be normally operated; in addition, the vertical distance between the water surface of the cyclone well and the well mouth is more than 15 meters, so that sundries are fished, although some operators try to use the grab bucket to fish, because the grab bucket is tightly sealed when closed, accumulated water in the grab bucket cannot be quickly filtered at the bottom, and at the moment of just discharging the water surface, floaters can return to the well again from the upper part of the grab bucket along with overflow water, so that the difficulty in cleaning the floaters is increased.
