Description

Technical Field

[0001] The utility model relates to the technical field of stirring blades, in particular to an assembled stirring blade. Background Technique

[0002] The stirring blade is one of the most important components in the stirring device. Selecting appropriate blades can ensure the stirring effect and process efficiency. Common stirring blades have various different forms, including downward pressing type, vertical spiral belt type, straight paddle type, and so on.

[0003] The stirring blade is usually arranged in the stirring device. Since the stirring blade needs to rub against the material for a long time, the stirring blade is easily worn. Compared with other components, it requires more frequent maintenance, inspection and replacement. In the prior art, multiple groups of blades are usually arranged for the stirring blade, and the blades are connected by welding. When one or more groups of blades are damaged, the whole blade usually needs to be replaced, or the blade is repaired by using repair welding. Therefore, it takes a long time to repair the blade. For this reason, an assembled stirring blade is proposed. Content of the Utility Model

[0004] The purpose of the utility model is to make up for the deficiencies of the prior art and provide an assembled stirring blade.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: an assembled stirring blade, including a first sleeve, and further including:

[0006] A disassembly and assembly component, which is arranged on the first sleeve and is used for installing or replacing the stirring blade;

[0007] Among them, the disassembly and assembly component includes a plurality of groups of first fixed shafts. The first fixed shafts are installed on one side of the first sleeve and are equidistantly distributed on the outer periphery of the first sleeve. A first arc plate is sleeved on the outer surface of the first fixed shaft, and a stirring blade body is welded on the outside of the first arc plate. A second sleeve is sleeved in the middle of the first sleeve. A first notch is opened inside the second sleeve. A second fixed shaft is installed inside the first notch. A limiting part and a return spring are sleeved on the outer surface of the second fixed shaft. A second arc plate is installed on the outside of the limiting part. A circular groove is opened on the inner wall of the second sleeve, and a second notch is opened on the inner wall of the first sleeve.

[0008] As described above, the end of the first fixed shaft passes through the second sleeve and is sleeved with the second sleeve, and the second sleeve is in pressing contact with the first arc plate.

[0009] As described above, the return spring elastically supports between the limiting part and the first notch.

[0010] As described above, the limiting member is movably clamped with the second notch, and adjacent two groups of first arc plates are in contact with each other and form a ring.

[0011] As described above, chamfers are provided on both the upper and lower sides of the second arc plate, and the second arc plate is in extrusion contact with the external stirring rod.

[0012] As described above, when the second arc plate is extruded, it can be embedded into the inner wall of the circular groove.

[0013] Compared with the prior art, the one-piece stirring blade has the following beneficial effects:

[0014] First, through the cooperation between the first arc plate and the first fixed shaft, the present utility model can assemble the stirring blade body. At the same time, through the cooperation between the second sleeve and the first sleeve and between the second sleeve and the first fixed shaft, the first arc plate will be limited. At this time, through the cooperation between the limiting member and the second fixed shaft, when the stirring rod is assembled on the inner wall of the second sleeve, the second arc plate will be extruded, so that the second sleeve and the first sleeve can be limited through the cooperation between the limiting member and the second notch, thereby facilitating the replacement of single or multiple groups of stirring blade bodies.

[0015] Second, by providing the first sleeve, the second sleeve and the first arc plate, the overall impeller is separated into different parts. When the stirring blade body is damaged, it is convenient to disassemble it separately, reduce the cost of its replacement, and can replace multiple groups of stirring blade bodies at the same time, improving the repair efficiency.

[0016] Other advantages, objectives and features of the present utility model will be described to some extent in the subsequent specification, and to some extent, will be obvious to those skilled in the art based on the study of the following text, or can be taught from the practice of the present utility model.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] As Figures 1-4 shown, the present invention provides an assembled stirring blade, including a first sleeve 1, and further including:

[0024] A disassembly and assembly component, which is arranged on the first sleeve 1 and is used for installing or replacing the stirring blade;

[0025] Among them, the disassembly and assembly component includes several groups of first fixed shafts 2. The first fixed shafts 2 are installed on one side of the first sleeve 1 and are evenly distributed on the outer periphery of the first sleeve 1. The outer surface of the first fixed shaft 2 is sleeved with a first arc plate 3. The outer side of the first arc plate 3 is welded with a stirring blade body 4. The middle part of the first sleeve 1 is sleeved with a second sleeve 5. The inside of the second sleeve 5 is provided with a first notch 6. A second fixed shaft 7 is installed inside the first notch 6. The outer surface of the second fixed shaft 7 is sleeved with a limiting member 8 and a return spring 9. The outer side of the limiting member 8 is installed with a second arc plate 10. A circular groove 11 is provided on the inner wall of the second sleeve 5, and a second notch 12 is provided on the inner wall of the first sleeve 1.

[0026] Through the cooperation between the first arc plate 3 and the first fixed shaft 2, the stirring blade body 4 can be assembled. At the same time, through the cooperation between the second sleeve 5 and the first sleeve 1 and between the second sleeve 5 and the first fixed shaft 2, the first arc plate 3 will be limited. At this time, through the cooperation between the limiting member 8 and the second fixed shaft 7, when the stirring rod is assembled on the inner wall of the second sleeve 5, the second arc plate 10 will be extruded, so that the second sleeve 5 and the first sleeve 1 can be limited through the cooperation between the limiting member 8 and the second notch 12, and further the first arc plate 3 can be positioned.

[0027] As Figure 1 shown, the end of the first fixed shaft 2 passes through the second sleeve 5 and is sleeved with the second sleeve 5. The second sleeve 5 is in pressing contact with the first arc plate 3.

[0028] Through the cooperation between the first fixed shaft 2 and the second sleeve 5, the rotation of the first arc plate 3 along the outer surface of the first sleeve 1 will be restricted. At the same time, through the cooperation between the first arc plate 3 and the second sleeve 5, the separation of the first arc plate 3 from the first fixed shaft 2 can be restricted, facilitating the positioning of the first arc plate 3 and the stirring blade body 4.

[0029] As Figure 4 shown, the return spring 9 is elastically supported between the limiting member 8 and the first notch 6.

[0030] Through the design of the return spring 9, the limiting member 8 has good elastic reset performance. At this time, since the return spring 9 is in a compressed state, a elastic force will be applied to the limiting member 8, thereby being able to drive the limiting member 8 to separate from the second notch 12, facilitating the disassembly of the first sleeve 1 and the second sleeve 5, and further enabling the replacement of single or multiple groups of stirring blade bodies 4.

[0031] As Figure 1 、 2 、4 shown, the limiting member 8 is movably clamped with the second notch 12, and the adjacent two groups of first arc plates 3 are in contact with each other and form a ring.

[0032] Through the cooperation between the limiting member 8 and the second fixed shaft 7, the limiting member 8 can move along the outer surface of the second fixed shaft 7, thereby driving the limiting member 8 into the interior of the second notch 12. When the limiting member 8 is clamped with the second notch 12, the movement of the second sleeve 5 and the first sleeve 1 will be restricted, thereby being able to limit the first arc plate 3 and the stirring blade body 4.

[0033] As Figure 3 shown, chamfers are provided on both the upper and lower sides of the second arc plate 10, and the second arc plate 10 is in pressing contact with the external stirring rod.

[0034] Through the chamfers provided on the outer side of the second arc plate 10, when the stirring rod is assembled on the inner wall of the second sleeve 5, the limiting member 8 will be driven to move along the outer surface of the second fixed shaft 7 through the second arc plate 10, thereby being able to limit the first sleeve 1 and the second sleeve 5 through the cooperation between the limiting member 8 and the second notch 12.

[0035] Working principle:

[0036] When a certain set of stirring blade bodies 4 is damaged, the second sleeve 5 is removed from the stirring rod to relieve the extrusion on the second arc plate 10. At this time, due to the elastic force of the return spring 9, the limiting member 8 will be extruded, so that the limiting member 8 can be driven to separate from the second notch 12 and the first sleeve 1 and the second sleeve 5 are released from the limit. At the same time, through the cooperation between the second sleeve 5 and the first sleeve 1 and between the second sleeve 5 and the second notch 12, the second sleeve 5 can be driven to separate from the first sleeve 1 and the limit on the first arc plate 3 is released. At this time, through the cooperation between the first arc plate 3 and the first fixed shaft 2, the stirring blade body 4 can be replaced.

[0037] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
