Abstract

The utility model belongs to the technical field of preparation equipment and discloses a flotation machine tailings gate plate in order to increase the overflow length and the rigidity of the gate plate. According to the technical scheme, the plate face of the gate plate is rectangular, and the long edges of the plate face of the gate plate are located in the horizontal positions; overflow grooves are cuboid, the top face and one end face of each cuboid overflow groove are open, the open end faces are connected with the upper end of the plate face of the gate plate, the open top faces face upward, and the top faces are flush with the upper edges of the gate plate; the overflow grooves are evenly arranged along the upper edges of the plate face of the gate plate, notches are formed in the connection positions of the plate face of the gate plate and the overflow grooves, and the notches are matched with the open end faces of the overflow grooves in shape; a gate plate pull plate is welded to the edge of the upper end of the gate plate, and a pull rod is connected to the gate plate pull plate. As the several overflow grooves are additionally formed in a steel plate of the gate plate, the overflow length of the gate plate is far larger than a plane-type gate plate, the overflow grooves and a gate plate body are connected into the whole gate plate, and the rigidity of the gate plate is increased. The flotation machine tailings gate plate has the advantages of being simple in structure, larger in overflow length and high in rigidity.

Description

A kind of tailings flashboard of flotation machine

Technical field

The utility model relates to a kind of tailings flashboard of flotation machine of special construction, belongs to the preparation equipment technical field.

Background technique

The tailings flashboard of flotation machine is by electric actuator or handwheel control lifting, in order to regulate liquid level height in the flotation trough.Traditional tailings flashboard of flotation machine generally is made of a plane steel plate and pull bar, and tailings liquid stream overflows along the plane steel plate upper end-face edge.Large scale development along with flotation machine, the length of flashboard is more and more wider, so that in design super sized type flotation machine, calculate the required effective overflow length of flashboard near groove width, so long steel plate is difficult to guarantee its rigidity in addition, needs therefore that a overflow length of redesign can be satisfied the demand, boundary dimension length is less, the easy guaranteed flashboard of rigidity.

The model utility content

Technical problem to be solved in the utility model provides the tailings flashboard that a kind of simple in structure, overflow length is long, boundary dimension is less.

The technological scheme that solves the problems of the technologies described above is:

A kind of tailings flashboard of flotation machine, comprise flashboard in its structure, bypass channel, the flashboard arm-tie, pull bar, the plate face of flashboard is rectangular, flashboard is vertically placed, the long edge position of the plate face of flashboard is in horizontal position, bypass channel is a plurality of, bypass channel is cuboid, top and end face of bypass channel cuboid opens wide, the end face that opens wide is connected with the plate face of flashboard upper end, opens wide to face up, and the above flushes with the flashboard top edge, a plurality of bypass channels are evenly distributed along the plate face top edge of flashboard, there is gap plate face and the bypass channel joint of flashboard, and the end face that the shape of gap and bypass channel open wide is complementary, and the flashboard arm-tie is welded on the flashboard upper end-face edge, the flashboard arm-tie is vertical with the plate face of flashboard, and pull bar is connected on the flashboard arm-tie.

Above-mentioned tailings flashboard of flotation machine, described bypass channel cuboid top and following be rectangular, the above opens wide, an end face is square for what open wide, another end is top and following crossing horizontal line, two sides are right-angled triangle, two leg-of-mutton right angle sides in side and an end of being connected and vertical connection of flashboard plate face.

The beneficial effects of the utility model are:

The utility model has been set up several bypass channels at traditional flashboard steel plate, form circuitous overflow weir, on equal contour length, the overflow length of flashboard is far longer than the plane flashboard, bypass channel and flashboard are bonded into flashboard integral body, increased the rigidity of flashboard, flashboard is connected with electric actuator or handwheel with pull bar by the flashboard arm-tie, forms whole tailings flashboard.The utlity model has advantage simple in structure, that overflow length is long, the flashboard rigidity is high.
