[0019] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0020] like Figure 1-4 As shown, an adjustable-direction stirrer upper fixing device includes a mounting base 1, which is installed on the upper part of the inner wall of the reaction tank. A vertical stirrer guide rod 2 is swayed and connected to the mounting base. An angle adjustment mechanism 3 for fixing the swing angle of the stirrer guide rod is installed on the mounting base. In use, the stirrer is installed under the stirrer guide rod. The stirrer is swayed by manually driving the stirrer guide rod. At the same time, the angle adjustment mechanism fixes the swing angle of the stirrer guide rod, which is convenient for fixing in the dead corner of the tank bottom, making it easy to clean the sludge accumulation in the dead corner and avoid sludge accumulation in the dead corner.

[0021] In this embodiment, to achieve the swing connection between the stirrer guide rod and the mounting base: the mounting base includes a vertically arranged fixed mounting plate 4, which is bolted to the inner wall of the reaction tank. A horizontal cantilever support 5 is installed on the surface of the fixed mounting plate. The stirrer guide rod is swing-connected to the cantilever support. More specifically, a horizontal swing rod 6 is installed at the upper end of the stirrer guide rod. The middle part of the horizontal swing rod is rotatably connected to the cantilever support. In use, by rotating the horizontal swing rod, the stirrer guide rod at one end of the horizontal swing rod swings around the rotation axis of the horizontal swing rod, thereby realizing the swing of the stirrer guide rod.

[0022] In this embodiment, to fix the stirrer guide rod after it has swung to the desired position, the angle adjustment mechanism includes a fan-shaped rotating disk 7. The inner arc portion of the fan-shaped rotating disk is fixed to the end of the horizontal swing rod away from the stirrer guide rod. A horizontal swing limiting plate 8 is connected to the upper end of the fixed mounting plate. A portion of the outer arc region of the fan-shaped rotating disk is located on the swing limiting plate. The fan-shaped rotating disk and the swing limiting plate are fixed together by a pin assembly. In use, when the stirrer guide rod swings to the desired position, the fan-shaped rotating disk and the swing limiting plate are fixed together by the pin assembly, thus fixing the position of the stirrer guide rod. Specifically: the fan-shaped rotating disk is provided with a plurality of upper locking holes 9 spaced apart along the outer arc, the swing limiting plate is provided with a plurality of lower locking holes 10 that cooperate with the upper locking holes, the pin assembly includes a pin 11, the upper end of the pin is provided with an end 12, the diameter of the pin is not greater than the diameter of the upper locking hole and the lower locking hole, and the outer diameter of the end is greater than the diameter of the upper locking hole and the lower locking hole. In use, when the stirrer guide rod swings to the required position, one of the upper locking holes and the lower locking hole coincide. At this time, the pin is inserted to connect the fan-shaped rotating disk and the swing limiting plate, and at the same time, the upper end of the pin abuts against the fan-shaped rotating disk to realize the placement of the pin.

[0023] In this embodiment, in order to achieve the connection between the fan-shaped rotating disk and the horizontal swing rod, a welding groove 13 is provided on the edge of the inner arc area of ​​the fan-shaped rotating disk. The end of the horizontal swing rod is inserted into and welded into the welding groove. The welding position of the fan-shaped rotating disk should meet the following requirements: the lower surface of the fan-shaped rotating disk is located on the upper surface of the swing limit plate to avoid interference.

[0024] In this embodiment, in order to achieve a rotatable connection between the horizontal swing rod and the cantilever support, a rotating seat 14 is provided at the end of the cantilever support. A rotating hole 15 is provided in the middle of the rotating seat. A rotating shaft 16 that mates with the rotating hole is installed in the middle of the horizontal swing rod. The lower shaft section of the rotating shaft is rotatably connected to the rotating hole. The rotating shaft can be directly welded to the lower surface of the horizontal swing rod, or it can be fixed to the lower surface of the horizontal swing rod by bolts or other existing fixing methods. The rotatable connection between the horizontal swing rod and the cantilever support is achieved through the cooperation of the rotating shaft and the rotating hole.

[0025] In this embodiment, in order to facilitate the rotation of the horizontal swing rod, drive handles 17 are symmetrically welded to the middle of the left and right sides of the horizontal swing rod along its length. That is, drive handles are welded to the left and right sides of the rotation connection point of the horizontal swing rod, and the horizontal swing rod is rotated by the drive handles.

[0026] In this embodiment, to assist the swing of the stirrer guide rod, a base 18 is provided on the lower part of the inner wall of the reaction tank, and a hinge seat 19 is welded to the bottom side of the stirrer guide rod. The hinge seat and the base are connected by a rotating shaft. Specifically, a connecting rod 20 corresponding to the horizontal swing rod is welded to the bottom side of the stirrer guide rod, and a hinge seat is provided on the connecting rod. The hinge seat can be a sleeve type and is rotatably connected to the base through a rotating shaft. Of course, other rotational connection methods can also be used, as long as they can satisfy the synchronous swing of the bottom of the stirrer guide rod. At the same time, the stirrer guide rod is a rectangular rod, and the end of the horizontal swing rod is welded to the upper end face of the rectangular rod. Several reinforcing ribs 21 are welded between the side wall of the horizontal swing rod and the upper end face of the rectangular rod, so that the end of the horizontal swing rod is firmly welded to the horizontal swing rod.

[0027] In this embodiment, to achieve the propulsion-driven movement of sludge, an agitator 22 is slidably connected to the agitator guide rod. A rectangular sliding sleeve 23 is welded to the rear of the agitator. The rectangular sliding sleeve has a clearance opening 24 corresponding to the horizontal swing rod. In use, the rectangular sliding sleeve is fitted onto the agitator guide rod from the upper part. A chain 25 is connected to the agitator via a hook. The upper end of the chain is wrapped around the horizontal swing rod. Of course, other connection methods can also be used, as long as the agitator can be lifted when needed. Specifically, the agitator slides from the upper part of the agitator guide rod to the bottom by its own weight, so it is necessary to manually pull the chain to lift the agitator.
