Abstract
The invention relates to an underflow pump with a soft connection device, which comprises an underflow pump, a slurry inlet pipe and a slurry outlet pipe, wherein the slurry inlet pipe and the slurry outlet pipe are connected on two sides of the underflow pump respectively; the middle parts of the slurry inlet pipe and the slurry outlet pipe are communicated through the soft connection device respectively; and the material hardness of the soft connection device is smaller than that of the slurry inlet pipe and the slurry outlet pipe. The middle parts of the slurry inlet pipe and the slurry outlet pipe are communicated through the soft connection device respectively, and the material hardness of the soft connection device is smaller than that of the slurry inlet pipe and the slurry outlet pipe, so the soft connection device can reduce the harmful shock of the slurry inlet pipe and the slurry outlet pipe, and the service lives of an outlet pipe and related equipment of the underflow pump can be prolonged.
Description
Technical field
The present invention relates to a kind of underflow pump, especially relate to a kind of underflow pump with soft connection device.
Background technique
Owing to taked the flooded operation method, the low density ore pulp flows to deckered stock chest to the iron ore concentrate ore pulp in dehydration, is beaten to ceramic machine by the underflow pump after through thickner it being concentrated again and dewaters.Thickner and ceramic machine have the bigger discrepancy in elevation in course of conveying, so must use powerful underflow pump.
But powerful underflow pump can produce strong vibrations in course of conveying, and these harmful vibrations can cause the working life that reduces underflow pump discharge pipe and relevant device.
Be illustrated in figure 1 as existing underflow pump structure schematic representation, comprise valve 2, underflow pump 4, pulp-inlet pipe road 3 and pulp pipeline 6, this pulp-inlet pipe road 3 and pulp pipeline 6 are connected to the both sides of underflow pump 4.The vibrations of underflow pump 4 can have influence on the working life of the pulp-inlet pipe road 3 and the pulp pipeline 6 of steel matter.
Summary of the invention
The present invention has designed a kind of underflow pump with soft connection device, the technical problem of its solution is that the iron ore concentrate ore pulp is in dehydration, powerful underflow pump can produce strong vibrations in course of conveying, these harmful vibrations can cause the working life that reduces underflow pump discharge pipe and relevant device.
In order to solve the technical problem of above-mentioned existence, the present invention has adopted following scheme:
A kind of underflow pump with soft connection device, comprise valve, underflow pump, pulp-inlet pipe road and pulp pipeline, described pulp-inlet pipe road and pulp pipeline are connected to the both sides of described underflow pump, be communicated with by a soft connection device respectively in described pulp-inlet pipe road and pulp pipeline intermediate portion, the material hardness of described soft connection device is less than the material hardness of described pulp-inlet pipe road and pulp pipeline.
Further, described soft connection device is a rubber hose.
Further, the length of described rubber hose is between the 70cm to 90cm.
Further, described soft connection device two ends are provided with a flange plate respectively and are connected on the described pulp-inlet pipe road.
Further, described flange plate is connected on the described pulp-inlet pipe road by welding manner.
Further, described soft connection device two ends are provided with a flange plate respectively and are connected on the described pulp pipeline.
Further, described flange plate is connected on the described pulp pipeline by welding manner.
This underflow pump with soft connection device is compared with existing underflow pump, has following beneficial effect:
(1) the present invention is owing to be communicated with by a soft connection device respectively in pulp-inlet pipe road and pulp pipeline intermediate portion, the material hardness of this soft connection device is less than the material hardness of pulp-inlet pipe road and pulp pipeline, thereby this soft connection device can reduce harmful vibrations of pulp-inlet pipe road and pulp pipeline, thereby can prolong the working life of underflow pump discharge pipe and relevant device.
(2) soft connection device of the present invention can improve the utilization efficiency of underflow pump, reduces frequent that the underflow failure of pump takes place.
