Abstract

This invention relates to an impeller assembly for an adjustable impeller stirrer, consisting of a rotating hub and at least three impeller blades. The rotating hub has a base for mounting the impeller blades, characterized by a solid cylindrical base extending radially from the central axis. The end of the base has a cross-section, on which is an angle adjustment mechanism designed to actuate the impeller's angle adjuster. The impeller consists of blades and a blade base, where the blade base is a circular plate sized relative to the end of the hub base. The blade base has an angle adjuster designed to actuate the hub's angle adjustment mechanism, allowing the impeller face angle to be determined by the combined angle adjustment mechanism and adjuster when the blade base is fitted to the end of the rotating hub's base.

Claims (8)

1. The impeller assembly of an adjustable impeller stirrer consists of a rotating hub (10) and at least three impellers (20), with the rotating hub (10) acting as the intermediary for fitting the impellers (20) together. The rotating hub (10) has a central shaft (11) which has a slot (12) at its center and on the inner surface of the slot there is a slotted groove (121) for fitting onto the shaft of the stirrer (3) to rotate the impellers (20). The central shaft (11) is axially aligned with the shaft of the stirrer (3), and the rotating hub (10) has a base (13) for fitting the impellers (20), with the number of bases (13) equal to the number of impellers (20). The impeller assembly has the following characteristics: The base (13) is a solid cylinder that extends radially from the central shaft (11). The end of the base (110) is a cross-section. On the cross-section there is a hole (4) for threading bolts (41) to secure the impeller (20) to the hub base (13), and there is an angle adjustment mechanism (5) designed to match the angle adjuster (6) of the impeller (20). The impeller (20) consists of a blade (21) and a blade base (22), in which the blade (21) is attached to the blade base (22) perpendicular to the cross-section of the blade base (22) and extends out from the blade base (22) with the blade axis (2110) of the blade (21) aligned with the hub axis (131) of the hub base (13). The blade base (22) is a circular plate of size In relation to the hub end (110), at the blade base (22) there is a locking groove (221) for threading bolts (41) to secure the impeller (20) to the hub base (13), and at the blade base (22) there is an angle adjuster (6) designed to work in conjunction with the hub base (13) angle adjustment mechanism (5), so that when the blade base (22) is fitted onto the hub end (110) of the rotating hub (10), the oblique angle (40) of the impeller face (20) can be determined by the angle adjustment mechanism (5) and the angle adjuster (6) together, where the oblique angle (40) of the impeller face (20) is the angle formed between the hub base plane (A) and the impeller plane (B), where the hub base plane (A) is the plane defined by the axes of the central axis (11) and the hub axis (131), and the impeller plane (B) is the plane of the impeller (20). 2. An impeller assembly of an adjustable impeller stirrer, according to claim 1, where the angle adjustment mechanism (5) is a number of hub base holes (1101) and the angle adjuster (6) is assembled with a number of blade base holes (61) with a bolt (62). 3. The impeller assembly of a variable impeller stirrer according to claim 1, where the blade (21) is composed of the cone (211) and the body (212), where the cone (211) is attached to the base of the blade (22), when viewed on the impeller plane (B) the cone (211) is a truncated triangle whose head is fixed to the base of the blade (22), and the base of the triangle is attached to the body (212), and the body (212) has blade edges defined by a number of curves. 4. An impeller assembly of an adjustable impeller stirrer according to claim 3, where the cone portion (211) attached to the base (22) has a thickness of 40 mm and the blade (212) has a thickness of 7-12 mm. 5. An impeller assembly of an adjustable impeller stirrer according to claim 3, in which the blades (212) are curved upward from the impeller plane (B), with the front edges curving downwards and the rear edges curving upward. 6. The impeller assembly of the adjustable impeller stirrer, according to claim 1, is further assembled with a front cover (140) and a base (141) which is a cylinder with a diameter equal to the central axis (11) of the rotating hub (10). On the base there are several holes (1411) for threading bolts to fasten the base (141) to the rotating hub (10), and a cover (142) which is conical in shape at the very front of the cover and in front of the central axis (11) there are several holes (114) for fastening with bolts. 7. An impeller assembly of a stirrer with adjustable impeller angles according to claim 1 or 2, in which the angle adjustment mechanism (5) and the angle adjuster (6) adjust the impeller angle in the range of 0-180 degrees. 8. An impeller assembly of a stirrer with adjustable impeller angles according to claim 7, where the angle adjustment mechanism (5) and the angle adjuster (6) adjust the impeller angle in the range of 0-40 degrees.
