Abstract
The utility model relates to an open-type impeller non-blocking crushing pump. An inlet of the open-type impeller non-blocking crushing pump is provided with a cutter disc used for chopping sundries. The cutter disc can be used to cut and grind sundries entering the inlet of the open-type impeller non-blocking crushing pump effectively, therefore the sizes of the chopped sundries are in the range of the sizes of particles, which can be conveyed by the open-type impeller non-blocking crushing pump, and the open-type impeller non-blocking crushing pump can be used to convey the liquid containing large particles and long fibers.
Description
Technical field
The utility model relates to a kind of unshrouded impeller Non-blinding pump, particularly a kind of unshrouded impeller Non-blinding pump with the cutting knife dish.
Background technique
At present; Known unshrouded impeller Non-blinding pump is more typical Non-blinding pump form, and its 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 unshrouded impeller Non-blinding pump can not be carried large particle and long fibre material.Therefore, the unshrouded 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 unshrouded impeller Non-blinding pump; It can effectively grind the foreign material cutting that gets into the import of unshrouded impeller Non-blinding pump; The size of foreign material is cut in the size of grain scope that the unshrouded impeller Non-blinding pump can carry, thereby the unshrouded 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:
Unshrouded impeller Non-blinding pump inlet has the cutting knife dish, mainly comprises unshrouded impeller, quadrangular shape cutter head, movable knife disc, quiet cutterhead.The cutting knife dish of installing in unshrouded 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 edge of a knife 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.The aperture surface that quiet cutterhead cooperates with movable knife disc has five or more semicircular aperture runner.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 unshrouded impeller Non-blinding pump and carry, and reach to enlarge the purpose that the unshrouded impeller Non-blinding pump is carried liquid range.
The utility model advantage is: chopping gets into the foreign material of unshrouded impeller Non-blinding pump, makes the unshrouded impeller Non-blinding pump be suitable for carrying more liquid that contain foreign material more, especially contains 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 that the conveying of unshrouded impeller Non-blinding pump contains the sewage of 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. unshrouded 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 were contained in unshrouded impeller (4) import, movable knife disc (6) and axle (2) rotated together, and quiet cutterhead (7) is contained on the pump housing; Have a lot of half round runner on quiet cutterhead (7) inner peripheral surface, 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 unshrouded impeller (4) inlet channel that final formation is very little.
Claims (3)
1. a unshrouded impeller does not have the obstruction macerator pump, it is characterized in that: unshrouded impeller Non-blinding pump inlet has the cutting knife dish, comprises unshrouded impeller (4), quadrangular shape cutter head (5), movable knife disc (6), quiet cutterhead (7).
2. a kind of unshrouded impeller according to claim 1 does not have the obstruction macerator 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 unshrouded impeller according to claim 1 does not have the obstruction macerator 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.
