Abstract

The utility model discloses a cutting pump is with preventing stifled fixed cutting knife, which comprises a body, the body includes short main sword, long main sword and cutter body, and short main sword and long main sword all inwards set up on the cutter body, and long main sword quantity is greater than one, all is equipped with a short main sword between two long main swoves. The utility model provides a prevent stifled fixed cutting knife that cuts pump was used has following advantage: the cutting effect is good, and is efficient, and the cutting edge is not twined.

Description

Anti-blocking fixed cutting knife for cutting pump

Technical Field

The utility model relates to a sewage cutting pump technical field especially relates to a cutting pump is used prevents stifled fixed cutting knife.

Background

The water pump is a machine for conveying liquid or pressurizing liquid, and it can transfer the mechanical energy of prime mover or other external energy to the liquid to increase the energy of liquid, and is mainly used for conveying liquid including water, oil, acid-base liquid, emulsion, suspoemulsion and liquid metal, etc. With the continuous development of economy in China in recent years, people have more and more requirements on the functions of water pumps, such as: it is desirable that the water pump not only pump water but also waste in the water, such as waste paper, waste strapping tape, waste cloth, waste plastic bags, kitchen waste, etc. The cutting pump also presents a field of view for people. The cutting knife of traditional cutting pump is including fixed cutting knife and with the impeller cutting knife of fixed cutting knife cooperation cutting. The effect of cutting pump cutting is mainly decided by fixed cutting knife, but the effect of cutting pump cutting abandonment plastic bag on the present market is not good, current fixed cutting knife two sides external shape is identical, all there is the cutting edge, do so though can increase the life of cutting knife (with impeller cutting knife complex fixed cutting knife cutting edge wearing and tearing back, only need with fixed cutting knife change facial make-up can), but this kind of fixed cutting knife is at the actual cutting in-process, the plastic film that does not cut off completely can twine on fixed cutting knife, and the piece film can gather in three main tool point department, it is more to lead to the discarded object to be amasss more, final cutting pump can not continue work.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the not enough of above-mentioned technique and providing a cutting pump that effect of cutting is good prevents stifled fixed cutting knife for pump.

The utility model provides a prevent stifled fixed cutting knife for cutting pump, which comprises a body, the body includes short main sword, long main sword and cutter body, and short main sword and long main sword all inwards set up on the cutter body, and long main sword quantity is greater than one, all is equipped with a short main sword between two long main swoves.

In order to facilitate the falling of the scrap film, the surfaces of the short main knife and the long main knife facing the water inlet are inclined surfaces.

In order to facilitate the falling of the scrap film, the two side surfaces of the inclined surface are in arc transition with the inclined surface.

In order to facilitate fixing, the outer side of the cutter body is provided with a mounting hole.

The utility model provides a prevent stifled fixed cutting knife that cuts pump was used has following advantage: the cutting effect is good, and is efficient, and the cutting edge is not twined.

Detailed Description

In order to clearly understand the technical solution of the present invention, the present invention is further illustrated by the following embodiments in combination with the accompanying drawings.

Example 1:

the utility model provides a prevent stifled fixed cutting knife that blocks up that cutting pump was used, as shown in figure 1, including body 1, body 1 includes short main sword 2, long main sword 3 and cutter body 4, and short main sword 2 and long main sword 3 all inwards set up on cutter body 4, and long main sword 3 quantity is greater than one, all is equipped with a short main sword 2 between two long main swords 3. In this embodiment, 3 long main cutters 3 are provided.

Through the design, the short main knife 2 is additionally arranged between the long main knives 3, the cutting frequency is increased, the cutting is more finely divided, the passing performance is improved, the power of the cutting pump can be reduced under the same cutting effect, and the energy-saving effect is achieved.

The device cutting efficiency is high, and the piece trafficability characteristic is good, and is more energy-conserving under the same cutting ability.

Example 2:

in the anti-blocking fixed cutting knife for the cutting pump provided by the embodiment, in order to facilitate the falling of the debris film, as shown in fig. 2 to 5, except for the characteristics described in embodiment 1, the surfaces of the short main knife 2 and the long main knife 3 facing the water inlet are inclined surfaces 5.

In order to facilitate the falling of the chippings and films, the two side surfaces of the inclined surface 5 are in arc transition with the inclined surface 5.

In order to facilitate fixing, the outer side of the cutter body 4 is provided with a mounting hole 6.

Through above-mentioned design, inclined plane 5 enables the piece film and drops to the center along the inclined plane, and circular arc transition can prevent that the piece film from hanging in 5 both sides on inclined plane between the both sides face of inclined plane 5 and inclined plane 5, prevents that the plastic bag is gone up in the cutting edge winding, and the more convenient completion of mounting hole 6 can be fixed.
