Abstract
The utility model relates to a semi-open impeller non-clogging cutting pump. A cutter disk used for mincing sundries is arranged at an inlet of the semi-open impeller non-clogging cutting pump, the sundries entering the inlet of the semi-open impeller non-clogging cutting pump can be effectively cut and ground by the cutter disk, and the sundries are cut into particles which can be conveyed by the semi-open impeller non-clogging cutting pump, so that liquid containing large particles and long fibrous matters can be conveyed by the semi-open impeller non-clogging cutting pump.
Description
Technical field
The utility model relates to a kind of half-opened impeller Non-blinding pump, particularly a kind of half-opened impeller Non-blinding pump with the cutting knife dish.
Background technique
At present; Known half-opened impeller Non-blinding pump is typical Non-blinding pump form, and his no plugging performance is general, and the damage in impeller gap can increase along with the operation of pump gradually; Pump performance also can descend, and the half-opened impeller Non-blinding pump can not be carried large particle and long fibre material.Therefore, the half-opened impeller Non-blinding pump has significant limitation on the liquid range of carrying.
The model utility content
For addressing the above problem; The utility model is installed the cutting knife dish that is used to shred foreign material in the inlet of half-opened impeller Non-blinding pump; It can effectively grind the foreign material cutting that gets into the import of half-opened impeller Non-blinding pump; The size of foreign material is cut in the size of grain scope that the half-opened impeller Non-blinding pump can carry, thereby the half-opened impeller Non-blinding pump can be carried contain the liquid of large particle and long fibre material.
Realize that above-mentioned purpose adopted technological scheme be:
Half-opened impeller Non-blinding pump inlet has the cutting knife dish, mainly comprises half-opened impeller, quadrangular shape cutter head, movable knife disc, quiet cutterhead.The cutting knife dish of installing in half-opened impeller Non-blinding pump inlet is divided into movable knife disc and quiet cutterhead; Movable knife disc has cutter head, wherein includes high cutter head and low cutter head, and cutter head quantity is all more than or equal to two; Cutter head stretches out the quadrangular shape cutter head of certain altitude to axial direction; The edge of a knife and movable knife disc external diameter be to it, and be circular-arc on the circumferencial direction of movable knife disc external diameter, cooperates with quiet cutterhead internal surface.Quiet cutterhead has five or more semicircular aperture runner at the aperture surface that cooperates with movable knife disc.The foreign material of pump inlet place are cut and grind in the cooperation of the cutter head through movable knife disc and the semicircle aperture runner of quiet cutterhead, make it to be suitable for the half-opened impeller Non-blinding pump and carry, and reach to enlarge the purpose that the half-opened impeller Non-blinding pump is carried liquid range.
The utility model advantage is: can shred the foreign material that get into the half-opened impeller Non-blinding pump, make the half-opened impeller Non-blinding pump be suitable for carrying more liquid that contain different foreign material more, especially contain the sewage of large particle and long fibre material.
The utility model is on probation through the user, reflect respond wellly, can solve the problem of half-opened impeller Non-blinding pump conveying large particle and long fibre material.
Description of drawings
Fig. 1 is an embodiment's of the utility model an axial plane sectional view
Fig. 2 is the cooperation figure of same embodiment's cutting knife dish
Among the figure: 1. submersible motor, 2. spool, 3. grease chamber, 4. half-opened impeller, 5. cutter head, 6. movable knife disc, 7. quiet cutterhead, 8. impeller nut
Embodiment
Fig. 1 and Fig. 2 have confirmed in the present embodiment jointly; Before movable knife disc (6) and quiet cutterhead (7) all are contained in half-opened impeller (4) import; Movable knife disc (6) and axle (2) rotate together; Quiet cutterhead (7) is contained on the pump housing, has a lot of half round runner on quiet cutterhead (7) inner peripheral surface, and the runner both sides form two blades.When material got into, the cutter head (5) of the passive cutterhead of meeting (6) was thrown to the circumferencial direction of cutting device, the cutter head that can be rotated when material partly gets into half round runner (5) chopping and grinding, particle entering half-opened impeller (4) inlet channel that final formation is very little.
Claims (3)
1. a half-opened impeller does not have the obstruction cutting pump, it is characterized in that: half-opened impeller Non-blinding pump inlet has the cutting knife dish, comprises half-opened impeller (4), quadrangular shape cutter head (5), movable knife disc (6), quiet cutterhead (7).
2. a kind of half-opened impeller according to claim 1 does not have the obstruction cutting pump, it is characterized in that: the cutting knife dish comprises movable knife disc (6) and quiet cutterhead (7), and quiet cutterhead (7) aperture surface has five or more semicircular aperture runner.
3. a kind of half-opened impeller according to claim 1 does not have the obstruction cutting pump, it is characterized in that: movable knife disc (6) has cutter head (5), wherein includes high cutter head and low cutter head, and cutter head quantity is all more than or equal to two.
