Drawings
In order to illustrate the embodiments of the present invention more clearly, the drawings that are needed in the description of the embodiments will be briefly described below, and it is obvious that the drawings in the description below are only some embodiments of the present invention, and that other drawings can be obtained by those skilled in the art without inventive work.
Fig. 1 is a schematic view of the overall structure of the present invention in embodiment 1.
FIG. 2 is a schematic bottom view of a single blade in embodiment 2.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without any creative effort belong to the protection scope of the present invention.
As shown in fig. 1, embodiment 1, an impeller for a side-entry agitator includes a hub 1 and a blade 2, the hub 1 being used for connection to an agitator shaft. The inner end part of the blade 2 is provided with a blade shaft 3, namely, the end of the blade close to the shaft sleeve is provided with the integrally cast blade shaft. The outer circumference of the shaft sleeve 1 is provided with shaft holes 4, and the number of the shaft holes 4 corresponds to the number of the blades one to one. The shaft hole is located same anchor ring, and the leaf axle 3 is located in shaft hole 4 and with 1 fixed connection of axle sleeve, realizes the fixed connection to the blade, and in the blade passed through the leaf axle and enters the axle sleeve, the pressure transmission that will stir the in-process and produce for the axle sleeve, reduces the blade atress, avoids producing local stress concentration, effectively avoids the crackle to appear, and the relative axle sleeve 1 slope of blade 2 sets up, and inclination can be 40 or 45, forms the form of screw, improves stirring efficiency.
Further, shaft hole 4 is the blind hole, and leaf axle 3 is connected with axle sleeve 1 with blind hole interference fit and through the welding. The mode of splicing and welding is adopted, the welding mode of the traditional blade and the shaft sleeve is changed, the connection between the blade and the shaft sleeve is enhanced, and cracks at the connection position are avoided.
Further, the outer tip of blade 2 is equipped with arc pterygoid lamina 6, and the arc pterygoid lamina stretches out to the both sides of blade, and it is 10~50mm to stretch out highly, makes arc pterygoid lamina 6 and blade 2's cross section be the T font, and the setting up of arc pterygoid lamina can increase the stirring volume, and two can reduce the terminal wearing and tearing of blade. The arc-shaped wing plate 6 can be integrally formed with the blades and can also be connected through welding, and when the arc-shaped wing plate 6 is connected with the blades through welding, reinforcing blocks are welded between the arc-shaped wing plate 6 and the blades. In order to reduce the mass of the blade, lightening holes 7 and/or lightening slots 8 can be arranged on the blade 2 and the arc-shaped wing plate 6. The arc lightening grooves can be formed in the blades, the lightening holes are formed in the arc wing plates, so that the thickness of the blades is thin and thick, the blades are thick at places with large stress, and thin at places with small stress, the overall mass of the blades is reduced, the rotating efficiency is improved, and the stirring efficiency is further improved.
As shown in fig. 2, in example 2, the blade shaft 3 is provided with a thickened plate 5, and the thickened plate 5 is attached to the surface of the blade 2 by welding. The thickening plate is located at the back of the blade and used for enhancing the connection strength of the blade and the shaft sleeve, avoiding cracks and prolonging the service life. Preferably, the inside and the outer wall of the shaft sleeve 1 are provided with ceramic wear-resistant layers, and the blades 2 are provided with wear-resistant ceramic coating layers, so that the overall high-temperature resistance and corrosion resistance of the impeller are improved, the mechanical property is good, and the service life is further prolonged.
