Abstract

The utility model relates to a sewage pump with a shredding device. The sewage pump with the shredding device comprises a sewage pump and a pair of fixed cutter and rotary cutter which are matched, wherein an impeller is arranged in a sewage pump shell of the sewage pump; the fxied cutter is arranged on the sewage pump shell; and the rotary cutter is fixedly connected with the impeller. By the technical scheme, impurities such as iron scraps, iron wires, chopsticks and the like in fluid can be cut off effectively, and pig bones and ox bones in the fluid also can be shredded, so that the shredded impurities can pass through the impeller and the sewage pump smoothly, the damage of the impurities to the impeller is prevented, the work efficiency of the sewage pump is improved, and the service life of the sewage pump is prolonged; and the sewage pump is long in service life and convenient to disassemble and maintain.

Description

The pollution discharge pump that has shredding mechanism

Technical field

The utility model relates to a kind of pollution discharge pump, particularly relates to a kind of pollution discharge pump that has shredding mechanism.

Background technique

Pollution discharge pump in the prior art is divided into two kinds, and a kind of is to be suitable for less foreign material when carrying out blowdown work, and the foreign material in the sewage will result in blockage in pollution discharge pump easily, thereby seriously influence the life-span and the filth-discharging effect of pollution discharge pump; The leaf that second kind of pollution discharge pump is pollution discharge pump is provided with double cutting edge; This structural requirement impeller blade will have enough intensity; And it is not that foreign material are cut off, but carries out disrumpent feelings or smash, and this structure also is the foreign material blocking phenomenon to occur through regular meeting; And manufacturing process requirement is very high, and cost also increases relatively.

Summary of the invention

In view of this, the purpose of the utility model is to provide a kind of pollution discharge pump that has shredding mechanism, through the present technique scheme; Material feeding mouth place at pollution discharge pump is provided with shredding mechanism, and cutoff edge has enough hardness and rust resistance, can keep sharp for a long time; Before fluid enters into pollution discharge pump, at first to pass through shredding mechanism earlier, after foreign material are shredded by cutting knife; Make the foreign material of chopping to pass through impeller and pollution discharge pump smoothly, prevented the infringement of foreign material, improved the working efficiency of pollution discharge pump impeller; Prolonged the working life of pollution discharge pump, and dismounting, easy to maintenance.

In order to achieve the above object; The utility model is achieved in that a kind of pollution discharge pump that has shredding mechanism, includes pollution discharge pump; Be provided with impeller in the pollution discharge pump shell of said pollution discharge pump; Include dead knife and rotating knife that pair of matched is closed, said dead knife is arranged on the pollution discharge pump shell, and said rotating knife is connected with impeller mutually.

The internal surface of said dead knife and the outer surface of rotating knife are tapered respectively, are respectively arranged with penetrating window on the conical surface of said dead knife internal surface and rotating knife outer surface.

When work, the motor on the pollution discharge pump rotates, and drives the wheel rotation in the pollution discharge pump shell; The upper end of rotating knife is fixed on the impeller, and the dead knife that matches with it upwards is fixed on the pollution discharge pump shell, produces negative pressure in the wheel rotation pollution discharge pump shell; Fluid enters into pollution discharge pump through the penetrating window of dead knife and rotating knife; Foreign material are when getting into penetrating window, and the rotating knife of rotation can shred the foreign material of fluid the inside, and the foreign material that will be shredded successfully are displaced into outside the pollution discharge pump with fluid.

Adopt the beneficial effect after the technique scheme to be: a kind of pollution discharge pump that has shredding mechanism, through the present technique scheme, not only can effectively cut off foreign material such as iron filings in the fluid, iron wire, chopsticks; And can shred pig bone, the ox bone in the fluid, and make the foreign material that shredded to pass through impeller and pollution discharge pump smoothly, prevented the infringement of foreign material to impeller; Improved the working efficiency of pollution discharge pump; Prolonged the working life of pollution discharge pump, and long service life, dismounting and easy to maintenance.

Description of drawings

Fig. 1 is the utility model overall structure figure.

Fig. 2 is a shredding mechanism schematic representation in the utility model.

Fig. 3 is the dead knife plan view of shredding mechanism in the utility model.

Fig. 4 is the rotating knife plan view of shredding mechanism in the utility model.

Among the figure, 1 pollution discharge pump, 2 pollution discharge pump shells, 3 impellers, 4 dead knives, 5 rotating knifes, 6 penetrating windows.

Embodiment

To combine accompanying drawing that specific embodiment in the utility model is done further explain below.

As shown in the figure; The pollution discharge pump that has shredding mechanism that the utility model relates to; Include pollution discharge pump 1, be provided with impeller 3 in the pollution discharge pump shell 2 of said pollution discharge pump 1, include dead knife 4 and rotating knife 5 that pair of matched is closed; Said dead knife 4 is arranged on the pollution discharge pump shell 2, and said rotating knife 5 is connected with impeller 3 mutually.

It is tapered that the outer surface of the internal surface of said dead knife 4 and rotating knife 5 is respectively, is respectively arranged with penetrating window 6 on the conical surface of said dead knife 4 internal surfaces and rotating knife 5 outer surfaces.

In practical application; Produce shearing through dead knife 4 and rotating knife 5 relative movement, liquid is through the liquid in the penetrating window 6, under dead knife 4 and moving knife 5 continuous tangent effects; Foreign material in the liquid are cut into smaller volume, to discharge pollution discharge pump 1 through impeller 3.

The above is merely the preferable possible embodiments of the utility model, is not in order to limit the protection domain of the utility model.

Claims

1. a pollution discharge pump that has shredding mechanism includes pollution discharge pump, is provided with impeller in the shell of said pollution discharge pump; It is characterized in that; Include dead knife and rotating knife that pair of matched is closed, said dead knife is arranged on the pollution discharge pump shell, and said rotating knife is connected with impeller mutually.

2. the pollution discharge pump that has shredding mechanism according to claim 1 is characterized in that, the internal surface of said dead knife and the outer surface of rotating knife are tapered respectively, is respectively arranged with penetrating window on the conical surface of said dead knife internal surface and rotating knife outer surface.
