Description

Pump impeller structure

This creation is related to a pump impeller structure, especially one that is easy to disassemble, assemble and clean.

According to the fact, the impeller of the conventional pumping pump is generally made of aluminum or cast iron cast into one body, that is, the impeller body and the casing are integrally formed. However, once the water outlet of the impeller is blocked by debris such as gravel, the body and the shell cannot be disassembled, so they can only be removed one by one with a hard sharp object, which is not only troublesome and time-consuming, and sometimes even impossible to remove, thus reducing the amount of water output. , Sincerely needs to be improved.

In view of this, the creator of this project is germinating research and improvement, and finally has the creation of this creation.

The main purpose of this creation is to provide a pump impeller structure that is easy to disassemble, assemble and clean.

In order to achieve the above-mentioned purpose, this creative department includes:

A body, in the shape of an arc-concave disc, with a central through hole, a plurality of blades protruding from the inner surface, and a joint hole at the front and rear ends of the blades; and A shell is in the shape of a flat disc, each with a rotating shaft at the front and rear ends, and a plurality of perforations corresponding to the engaging holes on the surface, so that the body and the shell can be fixed by a plurality of screws. Make it have a plurality of water outlets; so as to be easy to disassemble, assemble, and easy to clean. In the above-mentioned pump impeller structure, the inner ends of the blades of the main body are recessed with an abutting surface, and the casing correspondingly has a base.

Here is a preferred feasible embodiment in conjunction with the accompanying drawings to detail the structural features and effects of this creation as follows, so as to make it easy to understand and agree with.

Please refer to Figures 1 to 4 at the same time. The structure of the pump impeller 1 of this creation includes a separate and independent body 2 and a shell 3. The body 2 is made of steel and is in the shape of an arc concave disc. It has a central through hole 21, and a plurality of blades 22 (generally 4) are protrudingly provided on the inner side surface. The blades 22 are in a curved spiral shape and are evenly distributed. Each of the front and rear ends has a wider reinforcing part, For opening an engaging hole 23 (such as a screw hole), the inner ends of the blades 22 are recessed with an abutting surface 24; It has an inner and outer rotating shafts 31, 32, and the surface has a plurality of perforations 33 (eight in total) corresponding to the engaging holes 23. The perforations 33 are centered on the inner and outer rotating shafts 31, 32 to form a cross shape According to the arrangement, the shell 3 is located on one side of the outer rotating shaft 32 and a circular base 34 is protrudingly provided to correspond to the abutting surfaces 24.

According to the above-mentioned structural combination, the main body 2 is attached to the outer surface of the casing 3 (a surface of the outer rotating shaft 32), so that the through holes 33 and the engaging holes 23 are aligned with each other, and then a plurality of screws 35 are used to penetrate through the through holes 33. And the joint hole 23 to fix the body 2 and the shell 3 together, and make the two formed with a water outlet 36 between every two blades 22, as shown in FIG. 4, that is, between the body 2 and the shell 3. There are a plurality of water outlets 36 (generally four); at this time, the rotating shaft 32 outside the casing is located in the central through hole 21 of the main body, and the abutting surface 24 of the main body blade abuts on the casing base 34. In addition, the outer side of the impeller 1 of this creation can be covered with a cover 4, but this is not the feature of this creation and will not be repeated.

As mentioned above, since the main body 2 and the casing 3 are fixed by a plurality of screws 35, when the impeller outlet 36 is blocked, the main body 2 and the casing 3 can be separated by loosening the screws 35. , Carry out cleaning and cleaning operations, and then re-attach the two screws and fix them. In use, it can be easily disassembled, assembled and cleaned, which is far more advanced than the conventional ones.

In summary, the specific structure disclosed in this creation embodiment is found to be unknown to the acquaintances after investigation, and can achieve the expected purpose and effect. It can be called a novel and progressive creation. A new type of creation is proposed according to law. patent application.
