Abstract

The present invention relates to paper pulp cutting pumps.Including the pump housing (1) and the impeller (2) being arranged in the pump housing (1), impeller (2) front is provided with retention device (3);The retention device (3) is an annular disk (31) structure, annular disk (31) position is corresponded on the pump housing (1) and is provided with the through-hole (32) being connected to the annular disk (31), and the suction unit (4) of what through-hole (32) connection is provided on the outside of the pump housing (1).The setting that the present invention passes through annular disk, by the rotation of impeller so that the impurity such as particle are under the influence of centrifugal force on the outside of pump housing admission chamber, that is it is in region locating for annular disk, and impurity is sucked out by suction unit, reduce the probability of impurity and impeller contact, the service performance for guaranteeing impeller, improves the service life of impeller.

Description

Paper pulp cutting pump
Technical field
The present invention relates to a kind of paper pulp cutting pumps, more particularly to a kind of paper pulp for preventing fiber and impeller blocking occur Cutting pump.
Background technique
During cutting pump conveys paper pulp, because of the characteristic of pumped (conveying) medium, it is fine that a large amount of wood fibre, fiber crops can be generated Dimension etc., fiber is easily wrapped on the components such as impeller and blocks during transportation, influences the transfer efficiency of pump;It simultaneously can be because The components such as this damage impeller cause the service life of pump to reduce, require further improvement.
Summary of the invention
The present invention can well hinder the impurity such as fiber in view of the foregoing drawbacks, and it is an object of the present invention to provide a kind of structure is simple Gear, and a kind of paper pulp cutting pump that can be cleared up very well.
Thus the technical solution adopted by the present invention is that: the present invention includes the pump housing (1) and is arranged impeller in the pump housing (1) (2), impeller (2) front is provided with retention device (3);
The retention device (3) is an annular disk (31) structure, correspond on the pump housing (1) annular disk (31) position be provided with The through-hole (32) of annular disk (31) connection is provided with the suction of what through-hole (32) connection on the outside of the pump housing (1) Device (4).
Suction unit (4) rear end connects filter device (5), and the filter device (5) includes Rose Box (51), setting The liquid outlet (53) in Rose Box (51) lower part is arranged in inlet (52) on Rose Box (51) top, and setting is being filtered Filtering sieve plate (54) in case (51).
The filter device (5) is provided with the return pipe (6) being connected to the liquid outlet (53), and the return pipe (6) will Liquid is delivered to again in the pump housing (1).
Filtering sieve plate (54) the upper and lower level setting, the aperture of upper level filter sieve plate (54) are greater than lower layer's filtering sieve plate (54) Aperture.
Cutter (7) are provided in the annular disk (31).
The invention has the advantages that 1) the setting of the invention by annular disk, by the rotation of impeller so that the impurity such as particle Under the influence of centrifugal force on the outside of the pump housing admission chamber, that is to say, that the region locating for the annular disk, and pass through suction Impurity is sucked out device, reduces the probability of impurity and impeller contact, guarantees the service performance of impeller, and that improves impeller uses the longevity Life;
2) present invention further can be by the good filtering of impurity by filter device, and can return again filtered liquid It transports in the pump housing, this avoid wastes, increase economic efficiency;
3) present invention further avoids impurity from being again introduced by the setting of filtering sieve plate so that contaminant filter ratio is more thoroughly In the pump housing, the damage to components such as impellers is formed.

Specific embodiment
The present invention includes the pump housing 1 and the impeller 2 that is arranged in the pump housing 1, and 2 front of impeller is provided with retention device 3;
The retention device 3 is 31 structure of an annular disk, corresponds to 31 position of annular disk on the pump housing 1 and is provided with and the annular The through-hole 32 that disk 31 is connected to is provided with the suction unit 4 what through-hole 32 is connected on the outside of the pump housing 1.
4 rear end of suction unit connects filter device 5, and the filter device 5 includes Rose Box 51, is arranged in Rose Box The inlet 52 on 51 tops, is arranged in the liquid outlet 53 of 51 lower part of Rose Box, and the filtering sieve plate being arranged in Rose Box 51 54。
The filter device 5 is provided with the return pipe 6 being connected to the liquid outlet 53, the return pipe 6 by liquid again It is delivered in the pump housing 1.
54 upper and lower level of the filtering sieve plate setting, the aperture of upper level filter sieve plate 54 are greater than the hole of lower layer's filtering sieve plate 54 Diameter.
Cutter 7 is provided in the annular disk 31.
The course of work of the invention are as follows: liquid enters in the pump housing 1, and under the turning effort of impeller, the impurity such as particle enter Within region locating for annular disk 31, and impurity chopping is realized under the action of 31 inner cutter 7 of annular disk, then fill in suction The swabbing action decline impurity and small amount of liquids for setting 4 are sucked out out of the pump housing 1, and then the liquid containing impurity enters Rose Box 51 It is interior, and the filtering by filtering sieve plate 54, so that impurity is trapped in Rose Box 51, liquid then passes through return pipe 6 and returns again It flow in the pump housing, is so recycled, avoid contact of the impurity with impeller, improve the service life of pump, have good Practicability.
