Embodiment 1

[0022] like figure 1 Shown: Preferred Embodiment 1 of the present invention: including submersible motor 1, rotating shaft 2 located at the output shaft end of submersible motor 1, bearing housing 3 located on the outer periphery of rotating shaft 2, mechanical seal seat 5 located below bearing housing 3, and the rotating shaft 1. The fixedly connected propeller 6 also includes a cutting device. The cutting device is composed of a fixed knife 7 and a rotary knife 8 with clearance fit. The fixed knife 7 is set on the mechanical seal seat 5, and the rotary knife 8 is set on the propeller 6. The area is located at the propeller 6 inlet.

[0023] The fixed knife 7 is connected with the mechanical seal seat 5 and the bearing seat 3 through screws 20, the rotary knife 8 is connected with the propeller 6 through a tight fit, and the propeller 6 is coaxial with the submersible motor 1. When working, the submersible motor 1 drives the propeller 6 Rotating, the sewage is guided by the ...

Embodiment 2

[0025] Preferred embodiment 2 of the present invention: the basic structure is the same as preferred embodiment 1, the difference is that the number of cutting grooves 9 is 18, the number of water channels 10 on the rotary knife 8 is 5, and the shafts of the guide rings 11, 12 The dip angle is 50°.

Embodiment 3

[0026] Preferred embodiment three of the present invention: the basic structure is the same as the preferred embodiment one, the difference is that the number of cutting grooves 9 is 24, the number of water channels 10 on the rotary knife 8 is 5, and the shafts of the guide rings 11, 12 The dip angle is 60°.

[0027] In the present invention, because the fixed knife 7 cooperates with the rotary knife 8 clearance, and the gap is small, before the dirt enters the propeller 6 inlet edge, it is first introduced into the cutting area by the guide rings 11, 12 of the rotary knife 8 and cuts. The number of cutting grooves 9 on the 7 is relatively large, being 12-24, and the number of water passage grooves 10 on the rotary knife 8 is 3 to 5, so the dirt by the present invention is cut up to more than 300 times per second, so The cutting effect is good, and the dirt is effectively shredded, thereby effectively preventing the dirt from winding the propeller 6 and preventing the motor fr...

Abstract

The invention discloses a safe and reliable submersible mixer with cutting function, which can effectively prevent the winding of dirt and avoid the motor overload, and has favorable mechanical sealing. The mixer comprises a submersible motor, a rotation shaft arranged at the output shaft end of the submersible motor, a bearing seat arranged at the peripheral region of the rotation shaft, a mechanical sealing seat arranged below the bearing seat, a propeller fixedly connected with the rotation shaft, and a cutting device consisting of a fixed knife and a rotary knife in clearance fit, whereinthe fixed knife is arranged on the mechanical sealing seat while the rotary knife is arranged on the propeller; and a cutting area is arranged at the inlet of the propeller. The invention is suitablefor the submersible mixer.

Description

technical field [0001] The invention relates to sewage treatment equipment, in particular to a submersible mixer. Background technique [0002] In the prior art, submersible mixers are mainly divided into mixing and stirring submersible mixers and push-flow submersible mixers, which are mainly used in biochemical reaction tanks of modern sewage plants. Prevent sludge and dirt from settling. The existing submersible mixer has the characteristics of compact structure, large thrust, wide mixing area, convenient operation and maintenance, etc., so it is widely used in sewage treatment projects. [0003] However, with the deepening of sewage treatment technology and the expansion of application fields, especially the application of submersible mixers in industrial and mining enterprises and agricultural environmental protection, the existing submersible mixers mainly have the following shortcomings or defects: [0004] 1. Dirt, especially fibrous dirt, is easy to entangle, resu...
