Description

Technical Field

[0001] The invention relates to the technical field of balance detection of a stirring blade, and in particular to a stirring blade balance detection device. Background Art

[0002] Submersible mixers, also known as submersible propellers, are used in the process flow of sewage treatment plants to propel and stir sewage containing suspended matter, thin sludge, industrial process liquids, etc., to create water flow, enhance the stirring function, and prevent sludge sedimentation. They are important equipment in the process flow of municipal and industrial sewage treatment. They are divided into mixing submersible mixers and low-speed submersible propulsion mixers.

[0003] The stirring function of other mixers, including submersible mixers, is achieved through the rotation of the stirring blades. During the stirring process, in order to reduce the resistance of the stirred medium to the stirring blades and thus reduce the energy consumption of the motor, it is necessary to ensure the balance of the stirring blades during the rotation process as much as possible, which requires the center of gravity of the stirring blades to be located at the axis of the central rotating shaft of the stirring blades.

[0004] Therefore, the mixing blades need to be inspected for quality before they leave the factory to ensure that they meet the quality requirements. However, at present, whether the mass center of the mixing blade is located at the center axis of the mixing blade can generally only be determined by observing the shaking of the mixing blade in the rotating state; this makes the inspection of the mixing blade relatively cumbersome. Although static inspection has the advantages of convenient inspection and no hidden dangers of damage to the mixing blade during inspection, there is currently no relevant special inspection device for the mass center inspection of the mixing blade in a static state. Summary of the invention

[0005] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a stirring blade balance detection device with a simple structure and easy operation. Whether the stirring blade meets the quality requirements can be judged directly by observing whether the position of the slider to which the stirring blade is fixed is the same as the position of the slider not to which the stirring blade is fixed; through the action of the pointer and the indicating notch, it can be more conveniently and accurately observed whether the stirring blade meets the quality requirements; through the action of the flange A, the slider can move more stably along the circular arc groove A; through the action of the limit plate, the slider is prevented from sliding out from the two ends of the circular arc groove A during movement; through the action of the connecting rod, the connection strength between the support legs of the stand is improved.

[0006] The technical solution adopted by the invention is:

[0008] A further improvement of the present invention is that flanges A are symmetrically provided on both sides of the bottom of the arc groove A, the cross-section of the slider is a "U"-shaped structure matching the flange A, and rollers connected to the top and bottom of the flange A are respectively provided on the two side walls of the slider.

[0009] A further improvement of the present invention is that the notch of the arc groove A is provided with a notch, a limiting plate is fixed to the notch, and the side wall of the limiting plate is flush with the edge of the flange A.

[0010] A further improvement of the present invention is that the limit plate is fixedly connected to the notch by means of fixing bolts.

[0011] A further improvement of the present invention is that a pointer is fixed on the end face of one of the uprights facing away from the other upright and located at the lower part of the arc groove A, and an indicating notch is provided at the bottom of the side wall of the slider corresponding to the pointer side, and when the slider is in a free state, the needle tip of the pointer is located within the range of the indicating notch.

[0012] A further improvement of the present invention is that the side wall of the stand corresponding to one side of the pointer and located at the lower part of the sliding block is provided with an arc groove C which is concentric with the arc groove A, and flanges B are respectively provided inwardly at the notches on both side walls of the arc groove C. The needle tail of the pointer is fixed on a connecting block, and the cross-section of the connecting block is an "H"-shaped structure matching the arc groove C and its flanges B. The connecting block is fixed to the arc groove C by a locking bolt.

[0013] A further improved solution of the present invention is that the rollers are symmetrically arranged at two ends of the slider.

[0014] A further improvement of the present invention is that support legs are respectively provided at both ends of the bottom of the stand, and the connecting rod fixedly connects two adjacent support legs.

[0015] A further improvement of the present invention is that the support legs of two adjacent stands are fixedly connected by two parallel connecting rods.

[0016] A further improvement of the present invention is that the upper connecting rod between the supporting legs of two adjacent frames is flush with the bottom of the frames, and the lower connecting rod between the supporting legs of two adjacent frames is flush with the connecting rod between the supporting legs of the same frame.

[0017] The beneficial effects of the present invention are:

[0018] First, the stirring blade balance detection device of the present invention has a simple structure and is easy to operate. It can be judged whether the stirring blade meets the quality requirements by directly observing whether the position of the slider fixed with the stirring blade is the same as the position of the slider not fixed with the stirring blade.
