Abstract
The utility model discloses a sand removing and slurry leveling pump, comprising a power device, a pump body, a centrifugal impeller, a feeding opening and a discharging opening, wherein the pump body is vertical; the lower part of the pump body is connected with a conical sand remover; and a spiral impeller coaxial with the centrifugal impeller is arranged at the lower part of the centrifugal impeller inside the pump body. The vertical pump body is arranged on the sand removing and slurry leveling pump provided by the utility model; the conical sand remover is arranged at the lower part of the pump body; a spiral impeller is arranged inside the pump body; and after slurry enters the feeding opening at the bottom of the pump body, impurities such as sand and the like obtain a large centrifugal force under the effect of the spiral impeller, and are sunk along the wall of the pump body under the effect of the own gravity and are discharged from the lower part of the sand remover, so that the damage on a slurry pump can be reduced; the service life of the equipment can be prolonged; and the quality of paper slurry can be improved.
Description
Technical field
The utility model relates to the paper pulp machinery field, is specifically related to a kind of sand-removing slurry lift pump.
Background technique
The stock pump that uses in the existing paper-making industry only has the slurry of putting forward function, because paper pulp particularly in the straw pulp, often contains the hard foreign material such as silt, and fragile impeller and the pump housing, stock pump is short common working life, and amount of maintenance is large, and user cost is high.
The model utility content
The technical problems to be solved in the utility model provides a kind of stock pump of carrying with desanding function.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of sand-removing slurry lift pump, comprise power plant, the pump housing, centrifugal impeller, material feeding mouth and discharge port, the described pump housing is vertical, pump housing bottom and conical sandtrap join, and the bottom of centrifugal impeller is provided with coaxial with it helical runner in the pump housing.
As a kind of improvement, described helical runner is the bending moment helical runner.
As a kind of improvement, the lower exit place of described conical sandtrap is provided with the sediment outflow pipeline of straight-tube shape.Realize better the guidance quality that the sediment outflow process is good.
The technical solution adopted in the utility model, its beneficial effect is: because the utility model is provided with the vertical pump housing, pump housing bottom is connected to conical sandtrap, be provided with helical runner in the pump housing, after slurry enters from the material feeding mouth bottom the pump housing, under the effect of helical runner, the impurity such as sand grains obtain larger centrifugal force, under the self gravitation effect, sink along pump housing wall, and discharged by the bottom of sand remover, thereby when carrying slurry, effectively removed the impurity such as sand grains, reduced the infringement to stock pump, prolong service life of equipment, improved pulp quality.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is a kind of embodiment's of the utility model structural representation.
Embodiment
A kind of embodiment's of the utility model structural representation as shown in Figure 1, a kind of sand-removing slurry lift pump, it comprises power plant 1, the pump housing 2, centrifugal impeller 3, material feeding mouth 4 and discharge port 5, the pump housing 2 is vertical, the pump housing 2 bottoms and conical sandtrap 6 join, and the bottom of the pump housing 2 interior centrifugal impellers 3 is provided with coaxial with it helical runner 7.
In the present embodiment, described helical runner 7 is the bending moment helical runner.The lower exit place of described conical sandtrap 6 is provided with the sediment outflow pipeline 61 of straight-tube shape, realizes better preferably guidance quality of sediment outflow process.
The utility model in use, after slurry enters the pump housing from the material feeding mouth bottom the pump housing, under the effect of helical runner, the impurity such as sand grains obtain larger centrifugal force, sink along pump housing wall under the self gravitation effect of the impurity such as sand grains simultaneously, and discharged by the bottom of sand remover, thereby when carrying slurry, effectively removed the impurity such as sand grains, reduced the infringement to stock pump, prolong service life of equipment, improved pulp quality.
Except above preferred embodiment, the utility model also has other mode of execution, those skilled in the art can make various changes and distortion according to the utility model, only otherwise break away from spirit of the present utility model, all should belong to the defined scope of the utility model claims.
