Description
Technical Field
The utility model relates to a front-mounted filtering structure for a vertical heavy medium slag slurry pump, and belongs to the technical field of centrifugal pumps.
Background
The vertical slurry pump is a centrifugal pump for conveying slurry with high solid content, and is widely applied to stations of slag water treatment, sump drainage and the like in industries such as power plants, coal chemical industry, alumina, mine metallurgy and the like. Because the slurry of the slag water contains larger solid particles or fiber tissue, once the slurry is sucked into the pump body, the flow channel is easy to block, so that the pump can not work normally, and a filtering structure is generally arranged at the suction inlet of the pump to prevent the larger solid from entering the pump body.
The leading filtration for traditional pump is at the fixed filter mantle of pump body entry end, prevents that great solid from getting into the pump body, and this filter mantle and pump body entry end flange joint when needs clearance filter mantle, the dismouting difficulty.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the problems that the traditional front-mounted filter structure for the pump is easy to block, a filter cover is difficult to disassemble and assemble and the like, and provides the front-mounted filter structure for the vertical heavy medium slurry pump.
The purpose of the utility model is realized by the following technical scheme:
the utility model discloses a front-mounted filtering structure for a vertical heavy medium slag slurry pump, which comprises a filtering cover, a loop flange, a bolt and a nut;
the filter cover is a cylindrical support piece with an opening at the rear end, suction holes are formed in the front end face and the side wall of the filter cover, and a connecting flange with a bolt through hole is arranged on the outer edge of the rear end opening of the filter cover;
the loop flange is an annular combined piece formed by two semi-annular split pieces in an encircling manner, the inner ring of the loop flange annular combined piece is a conical surface converging backwards, and a group of bolt connecting holes which are uniformly distributed circumferentially are formed in the annular surface of the loop flange annular combined piece;
the outer edge of the opening part of the inlet end of the pump body is provided with a conical surface corresponding to the inner ring of the loop flange annular assembly;
the two semi-annular sub-parts of the loop flange are sleeved at the opening part of the inlet end of the pump body in a surrounding manner, and the conical surface of the inner ring of the loop flange annular sub-part is connected with the conical surface of the inlet end of the pump body; and the connecting flange at the rear end of the filter cover and the loop flange are locked by bolts and nuts, so that the pump body, the filter cover and the loop flange are fixed.
Advantageous effects
The front-mounted filtering structure for the pump is simple in structure, can realize quick assembly and disassembly of the filtering cover and the inlet end of the pump body, and effectively prevents large granular solid matters or fiber tissue matters in slag-water slurry from being sucked into the pump body to block a flow channel.
