Embodiment
The utility model provides a kind of water pump, and the structure of this water pump comprises as shown in Figure 1: the cutter plate 12 of the pump housing 11 that is connected with motor output shaft, the water inlet that is installed in the pump housing, the cutting blade 13 that is connected with pump housing output shaft.
The cutter plate 12 static water inlets that are installed in water pump, its structure such as Fig. 2, Fig. 3 and shown in Figure 4, as can be seen, with the equidistant circle in the center of circle on be evenly distributed with a plurality of holes 201, this hole 201 can be the circular hole shown in the figure, can be other shapes also, as slotted hole.Along same sense of rotation, each hole is provided with groove 202, and this groove 202 can be the shape of keyway, also can be other shapes; Radially, be provided with 4 radial grooves 203 that begin to finish from the center of circle to the edge, can assist and cut off the fibrous object that is wrapped on the cutting cutter shaft, radial groove 203 can be the straight line type shown in Fig. 2, also can be other shapes such as S type.
When water pump rotated, cutting blade 13 can rotate along with the rotation of pump housing axle, and the blade 52 on it will be with between cutting blade 13 and the cutter plate 12 or bulk waste on every side and the cutting and grinding of long fibre shape dirt.
In addition, because there is projection 521 at the back side of blade 52, thereby when water pump rotates, can around the sewage pump water inlet, form whirlpool, thereby dirt rotates with whirlpool around driving, under the centrifugal action of whirlpool, these dirts are inhaled in the water pump, are excluded then.
The quantity of blade 52 is not limited to three shown in the figure, and it can be one or more.
Above-mentioned first embodiment is to be provided with groove 202 for describing along same sense of rotation in each hole, but the utility model is not limited thereto, other distortion can also be arranged, for example: can directly be provided with one or more grooves along same sense of rotation cutter plate 12.
The impeller of cutter plate and cutting blade and water pump is independently: impeller is positioned at the inside of impeller cavity, and cutter plate and cutting blade are positioned at the water inlet of the outside of impeller cavity.Therefore this cutter plate and cutting blade be applicable to various water pumps, is particularly useful for being provided with the water pump of common half-open or full-open type impeller.
When this cutter plate and cutting blade are used in combination with the abrading type submersible pump, can reach than the better effect of independent use abrading type water pump.
When this cutter plate and cutting blade and swirl type water pump are used in combination, can more quickly dirt be discharged after bulk waste and the cutting and grinding of long fibre shape dirt.
When this cutter plate and cutting blade and common water pump half-open or the full-open type impeller are used in combination, under equal power level, can be higher than the working efficiency of swirl type water pump.This is because between swirl type water pump vane and the impeller cavity bigger gap is arranged, and forms whirlpool during the impeller rotation in impeller cavity, and the centrifugal force of whirlpool throws away liquid, and this moment, impeller did not directly contact with granular or fibrous dirt; And this cutting device and common water pump half-open or the full-open type impeller be when being used in combination, and the impeller of the water pump of common half-open or full-open type impeller still can contact with sewage, thereby can reach higher working efficiency.
Second embodiment that the utility model provides is a kind of cutting device, and this cutting device comprises cutter plate and cutting blade, and this cutter plate is fixed on the water intake outside of the pump housing, and cutting blade is installed on the output shaft of the pump housing.The structure of this cutter plate and cutting blade and above-mentioned first embodiment's description is similar, is not described in detail here.
The technological scheme that is provided by above-mentioned the utility model as can be seen, the utility model is by cutter plate that is installed in described pump housing water intake and the cutting blade that is installed in pump housing output shaft, can be when the pump housing turns round, with bulk waste and the cutting and grinding of long fibre shape dirt on every side, be choked with filth, contain block or fibrous impurity problem thereby can solve, and can improve the Security of pump equipment operation by water pump.
The above; it only is the preferable embodiment of the utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
