Technical field
The invention belongs to iron ore concentrate long distance transportation pipe technology field, be specifically related to a kind of deckered stock chest underflow pump ingress filtering device.
Background technique
The iron ore concentrate deckered stock chest generally all is the open type pond, being easy in process of production foreign matter drops in the pond, once falling in the pond, object will enter in the underflow pump along with iron ore concentrate flows into conveyance conduit, not only cause foreign matter to the damage of the pump housing, affect manufacturing efficiency but also can therefore stop production, finally cause unnecessary economic loss.
Summary of the invention
The present invention designed a kind of deckered stock chest underflow pump ingress filtering device, thereby it has solved foreign matter in the deckered stock chest causes unnecessary economic loss to the damage of the underflow pump pump housing problem.
In order to solve the technical problem of above-mentioned existence, the present invention has adopted following scheme:
A kind of deckered stock chest underflow pump ingress filtering device comprises underflow pump (4) and deckered stock chest, it is characterized in that: the ore pulp delivery duct between underflow pump (4) and deckered stock chest is provided with filtrating equipment (2) with the foreign matter in the filtering ore pulp.
Further, filtrating equipment (2) is a container, and the inside of container is equipped with grid (21) container is separated at least two cavitys, and outermost two cavitys are connected with underflow pump (4), deckered stock chest respectively by ore pulp delivery duct.
Further, grid (21) with laterally, vertical or be arranged in the container with the horizontal plane angle that tilts.
Further, filtrating equipment (2) is that free demountable structure is so that the cleaning foreign matter.
Further, described container is a body, the vertical ore pulp delivery duct setting of body, grid (21) axially or radial arrangement in body, the bottom of body is provided with base plate (23), the top of body is provided with top cover (22), and dismountable the linking together with body of top cover (22) is convenient to clear up the foreign matter that filters out.
Further, the diameter of body is greater than the diameter of ore pulp delivery duct.
Further, the wall thickness of body is greater than the wall thickness of ore pulp delivery duct.
This deckered stock chest underflow pump ingress filtering device has following beneficial effect:
(1) ore pulp delivery duct of the present invention between underflow pump and deckered stock chest installed filtrating equipment additional, effectively protected the underflow pump equipment of high value, reduced unnecessary economic loss.
(2) filtrating equipment is dismountable structure among the present invention, can clear up at any time foreign matter, and is simple to operate, consuming time few.
(3) the present invention makes, installs simple.
(4) the body wall thickness of filtrating equipment of the present invention is greater than the wall thickness of ore pulp delivery duct, is eddy flow and design durable wear just during through filtrating equipment for ore pulp.
(5) pipe diameter of filtrating equipment of the present invention is greater than the diameter of ore pulp inlet duct and outer pipe, and the demand that can satisfy production output can not result in blockage or the underflow pump no load running.
