Description

A kind of hydrabrusher

Technical field

The utility model relates to a kind of hydrabrusher.

Background technology

Hydrabrusher is one of pulp crushing apparatus the most frequently used in paper mould product industry, main size degradation pulpboard, waste and old books, waste carton etc., is discongested the slurry after separation by sieve aperture to flow out, and foreign matter, heavy slag are then collected in sediment pot and regularly discharge.Due to the special construction of this serial hydrapulper rotor, when rotor turns round, slurry is dished out from center to surrounding, produces whirlpool, make pulpboard, broken obtain size degradation under hygrometric state in its center.Then do not discongested further in rotor and sieve plate gap by the scraps of paper of size degradation, fibre bundle, however current hydrabrusher pulping ability and throughput undesirable, pulping efficiency and size degradation effect also have greatly improved space.And the sieve aperture of traditional sieve plate is straight cylinder type structure, slurry will through longer distance to discharge sieve aperture by entering sieve aperture, and slurry is very large by resistance during sieve aperture, and flow velocity is low, and thus, pulper production capacity is low.

Utility model content

For the defect that above-mentioned background technology exists, the utility model provides a kind of hydrabrusher.

For realizing above-mentioned energy-conservation object, the technical solution adopted in the utility model is: it comprises motor and body, body comprises impeller of rotor, sieve plate, reduction box and shaft coupling, the below of impeller of rotor is located at by sieve plate, one end of shaft coupling is connected with the rotating shaft of motor, the other end of shaft coupling is connected with the input of reduction box, and the output of reduction box is connected with the rotating shaft of impeller of rotor

Impeller of rotor is uniform at least two impeller blades circumferentially, the curved strip of impeller blade, and highly different multiple impeller blade stagger arrangement are distributed in impeller body periphery, and are alternately distributed, and impeller blade bottom surface is provided with groove,

Sieve plate comprises the sieve plate body of annular, sieve plate body inward flange and outward flange are equipped with installing hole, sieve plate body is provided with sieve aperture, it is characterized in that: described each sieve aperture is formed by the cylindrical section of coaxial line and conical section, conical section comparatively small end is connected with cylindrical section, and conical section is equal with the internal diameter of cylindrical section compared with the internal diameter of small end.

Preferably, the cylindrical section of described sieve aperture and the length of conical section are than being 1:6.

The utility model has following beneficial effect: the utility model arranges on impeller blade, stator serrated knife ring body and arranges stator serrated knife on impeller of rotor body, certain interval is had to form pulping passage between impeller blade and stator serrated knife, when impeller of rotor rotates, impeller blade and the relative motion of stator serrated knife, paper pulp is produced shearing, rubbed and machine cuts effect, therefore size degradation is carried out to slurry, act on while multiple size degradation mode, thus substantially increase the size degradation ability of the utility model device.It is cylindrical that the sieve aperture of sieve plate body changes import into by straight cylinder structure, outlet is larger conical structure, and when slurry enters sieve aperture, sieve diameter becomes large gradually, sieve aperture reduces the resistance of slurry, slurry is smoothly through sieve aperture very much, and slurry is little by sieve aperture resistance, and flow velocity is high, pulper production capacity improves, through test, adopt the utility model to make hydrabrusher production capacity improve more than 15%, power consumption reduces greatly.

Detailed description of the invention

Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.

As shown in Figure 1, the utility model comprises motor 2 and body 1, body 1 comprises impeller of rotor 4, sieve plate 3, reduction box 6 and shaft coupling 5, the below of impeller of rotor 4 is located at by sieve plate 3, one end of shaft coupling 5 is connected with the rotating shaft of motor 2, the other end of shaft coupling 5 is connected with the input of reduction box 6, and the output of reduction box 6 is connected with the rotating shaft of impeller of rotor 4.

As shown in Figure 2, impeller of rotor 4 is uniform at least two impeller blades 102 circumferentially, the curved strip of impeller blade 102, and highly different multiple impeller blades 102 stagger arrangement is distributed in impeller body 101 periphery, and is alternately distributed.Impeller blade 102 bottom surface is provided with groove 104, contributes to turbulization around impeller blade 102, shears paper pulp, cleans impeller blade 102 and sieve plate 3 simultaneously, keeps clean, prevents blocking.

As shown in Figure 3, Figure 4, sieve plate 3 comprises the sieve plate body 31 of annular, sieve plate body 31 inward flange and outward flange are equipped with installing hole 32, sieve plate body 31 is provided with sieve aperture 33, each sieve aperture 33 is formed by the cylindrical section 34 of coaxial line and conical section 35, conical section 35 comparatively small end is connected with cylindrical section 34, and conical section 35 is equal with the internal diameter of cylindrical section 34 compared with the internal diameter of small end.The length of the cylindrical section 34 of sieve aperture 33 and conical section 35 is than being 1:6, and the internal diameter compared with small end and larger end of the conical section 35 of sieve aperture 33 is than being 4:5, and this ratio is a kind of design parameter reducing resistance, improve velocity optimization.Sieve aperture 33 due to sieve plate body 31 changes import into by original straight cylinder structure and is cylindrical section 34 (cylindrical), exports as larger conical section 35 (taper shape) structure, when slurry enters sieve aperture 33, sieve aperture 33 diameter becomes large gradually, the resistance of sieve aperture 33 pairs of slurries reduces, slurry is smoothly through sieve aperture 33 very much, slurry is little by sieve aperture 33 resistance, flow velocity is high, pulper production capacity improves, through test, adopt the utility model to make hydrabrusher production capacity improve more than 15%, power consumption reduces greatly.

The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
