[0018] The technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0019] Embodiment 1, as Figure 1-Figure 4 As shown, the utility model provides a sewage treatment agent mixing device for sewage treatment, which structure includes a dosing barrel 1 and a stirring device for stirring and mixing the agent in the dosing barrel 1, the stirring device includes a stirring shaft 3 and a plurality of stirring blades 4 arranged around the stirring shaft 3, the stirring shaft 3 is connected to a driving device 2, and the driving device 2 usually adopts a motor. Through the stirring action of the stirring device, the agent is fully mixed with water in the dissolving box.

[0020] Among them, the stirring blade 4 is swingably connected to the stirring shaft 3, and an adjustment mechanism 6 is provided on the stirring shaft 3 and is transmission-connected to the stirring blade 4. Under the action of the adjustment mechanism 6, the stirring blade 4 includes a contracted state leaning against the stirring shaft 3 and an expanded state expanding outward. For this purpose, the adjustment mechanism 6 includes a movable sleeve 61 and a connecting rod 62. The movable sleeve 61 is nested and installed on the stirring shaft 3, and the movable sleeve 61 retains the freedom to move along the axial direction of the stirring shaft 3 on the stirring shaft 3. One end of the connecting rod 62 is swingably installed at the bottom end of the movable sleeve 61, and the other end is connected to the stirring blade 4. The axial movement of the movable sleeve 61 drives the connecting rod 62 to control the swing of the stirring blade 4.

[0021] In the present embodiment, the stirring blade 4 in the retracted state is located below the swing connection point between the stirring blade 4 and the stirring shaft 3. In the basic setting optional by the technical personnel in this embodiment, the movable sleeve 61 may have a fixed installation position, that is, when the stirring blade 4 is in the retracted state, the movable sleeve 61 can move freely, and when the movable sleeve 61 drives the stirring blade 4 to swing upward to a preset position, a corresponding installation structure is also pre-provided between the movable sleeve 61 and the stirring shaft 3 at this position, such as a clamp, a pin or a bolt, which is used to limit the relative position between the movable sleeve 61 and the stirring shaft 3 in the axial direction, so that the stirring blade 4 can be kept in the expanded state for use all the time.

[0022] However, in this embodiment, not only that, a control part is retained at the top of the movable sleeve 61, which is used to move the movable sleeve 61 on the axis of the stirring shaft 3. Specifically, a bracket 5 is provided at the top of the dosing barrel 1 for installing the driving device 2, and the control part of the movable sleeve 61 is located in the bracket 5, and the bracket 5 is provided with an open space for manipulating the control part, so that the user can reach into the bracket 5 to adjust the control part, and the control part includes an adjusting bolt 64. A bearing 63 is fixed in the bracket 5, and the bearing 63 includes an inner ring 63a and an inner ring 63b. 3a is nested on the movable sleeve 61. It should be noted that the movable sleeve 61 and the inner ring 63a are clearance-matched; the portion of the movable sleeve 61 located above the bearing 63 is provided with a top plate 61a in an outwardly expanded shape, and the adjusting bolt 64 is installed on the top plate 61a by means of threads. It can be known that the adjusting bolt 64 can be a bolt, and the bottom of the adjusting bolt 64 is pressed against the structure of the inner ring 63a of the bearing 63. The stirring blade 4 in the retracted state is expanded as the length of the bottom of the adjusting bolt 64 extending out of the top plate 61a and abutting against the inner ring 63a of the bearing 63 increases.

[0023] During the specific implementation, the movable sleeve 61 is nested on the stirring shaft 3 and the top plate 61a is close to the bearing 63. At this time, the stirring blade 4 hangs down and is close to the stirring shaft 3, and is in a retracted state. At this time, the overall outer diameter of the stirring blade 4 in the retracted state is smaller than the equipment port provided at the top of the dosing barrel 1, which can be easily inserted. Then the stirring blade 4 is extended into the dosing barrel 1 and the motor bracket 5 is installed on the top of the dosing barrel 1. Then the adjusting bolt 64 is rotated to allow the bottom of the adjusting bolt 64 to gradually extend out of the top plate 61a and abut against the inner ring 63a of the bearing 63. At this time, the movable sleeve 61 is gradually lifted up, and the rising movable sleeve 61 drives the stirring blade 4 to swing upward through the connecting rod 62, so that the stirring blade 4 is expanded from the retracted state to the expanded state for stirring, and the angle required for the expanded state can be rotated and set according to the actual needs of technical personnel in this field. Therefore, compared with the prior art, a stirring blade 4 with a larger diameter can be used without being restricted by the equipment port of the dosing barrel 1.

[0024] Moreover, a top limit edge 63b is provided at the top of the inner ring 63a of the bearing 63, and a slot or a hole is provided on the top limit edge 63b. The bottom of the adjusting bolt 64 passes through the slot or the hole of the top limit edge 63b and contacts the main body of the inner ring 63a below the top limit edge 63b. A hoop 65 is nested at the bottom end of the adjusting bolt 64, and the outer diameter of the hoop 65 is larger than the width of the slot or the hole of the top limit edge 63b, thereby allowing the adjusting bolt 64 to be relatively stable in position with the movable sleeve 61 when in use.

[0025] Embodiment 2, on the basis of embodiment 1, the stirring blade 4 is inclined in the rotation direction in which it rotates following the stirring shaft 3, and the stirring blade 4 is in a sheet shape. When the inclined stirring blade 4 is unfolded to a horizontal state, the horizontal height of the front end in the rotation direction is lower than the horizontal height of the rear end. Therefore, during the stirring rotation, the liquid coming from the stirring blade 4 will apply pressure to the rear and lower part of the stirring blade 4, so that the movable sleeve 61 is subjected to a downward pulling force and has a downward movement tendency, and is more stable on the bearing 63.

[0026] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
