An adjustment mechanism 3 is provided between the two mobile bases 1 and the mounting plate 2. A stirring mechanism 4 is provided at the bottom of the mounting plate 2, and a curing agent conveying mechanism 5 is provided at the top of the mounting plate 2.

[0023] The adjustment mechanism 3 includes a dual-axis motor 301, and the dual-axis motor 301 is fixedly installed inside the two movable bases 1. A driving gear 302 is fixedly installed on the two output shafts of the dual-axis motor 301. The outer surfaces of the two driving gears 302 are meshed with driven gears 303. The interiors of the two driven gears 303 are fixedly installed with threaded rods 304, and the outer surfaces of the two threaded rods 304 are threadedly connected with threaded cylinders 305.

[0024] The tops of the two mobile bases 1 are each provided with a circular hole located on the outer surface of the two threaded rods 304. The tops of the four threaded cylinders 305 are fixedly connected to the four corners of the bottom of the mounting plate 2. When the driving gear 302 and the driven gear 303 are engaged, when the dual-axis motor 301 is started, the two threaded rods 304 can be rotated, so that the height of the mounting plate 2 can be adjusted by the threaded cooperation of the threaded cylinder 305 and the threaded rod 304, and then the height of the stirring mechanism 4 can be adjusted, so that it is convenient to adapt to containers of different heights and flexibly used in different containers to solidify the sludge.

[0025] Universal wheels are provided on both the front and rear sides of the bottom of the two mobile bases 1. The universal wheels can be used to easily move the device to a position where it is needed, and the device is flexible to use.

[0026] The stirring mechanism 4 includes a driving member 401, which includes a support frame fixedly mounted on the top of the mounting plate 2, a stirring motor 601 fixedly mounted on the bottom of the support frame, a gear 1 602 fixedly mounted on the output shaft of the stirring motor 601, the outer surface of the gear 1 602 is meshed with the gear 2 603, the interior of the gear 2 603 is fixedly mounted with a rotating rod 402, the bottom of the rotating rod 402 passes through the middle of the mounting plate 2 and is rotatably mounted therewith, and a stirring blade 403 is fixedly mounted on the outer surface of the rotating rod 402.

[0027] Under the action of the driving member 401, the rotating rod 402 can be driven to rotate, thereby driving the stirring blade 403 to rotate to perform a stirring operation.

[0028] The curing agent delivery mechanism 5 includes a curing agent storage box 501 and a pumping pump 502 . A pumping pipe 503 is installed at the inlet of the pumping pump 502 . A delivery pipe 504 is installed at the outlet of the pumping pump 502 . A delivery cavity 505 is opened inside the rotating rod 402 .

[0029] A feed hopper is fixedly installed on the top of the curing agent storage box 501, and a cover is provided on the feed hopper. A transparent window is provided on the front side of the curing agent storage box 501. The remaining amount of the curing agent storage box 501 can be observed through the transparent window. The cover can be opened to add curing agent to the feed hopper in time.

[0030] One end of the extraction pipe 503 is connected to the curing agent storage box 501, and one end of the delivery pipe 504 extends to the interior of the feeding chamber 505. The curing agent in the curing agent storage box 501 can be transported to the interior of the feeding chamber 505 through the extraction pipe 503 and the delivery pipe 504. Through the rotation of the rotating rod 402, the curing agent is thrown into the sludge and mixed with it.

[0031] It should be noted that the power supply and controller in the device are not shown. Since they are existing mature technologies, they will not be described in detail.

[0032] During implementation, follow these steps:

[0033] 1) First move the device to the sludge container;

[0034] 2) Then, by starting the two dual-axis motors 301, the two driving gears 302 are driven to rotate. The two driving gears 302 drive the two driven gears 303 to rotate, thereby driving the two threaded rods 304 to rotate. Under the threaded engagement of the threaded cylinders 305 and the threaded rods 304, the two threaded cylinders 305 move upward. The height of the mounting plate 2 is adjusted according to the height of the container, so that the stirring blade 403 enters the container.

[0035] 3) The fixed frame in the curing agent delivery mechanism 5 is then delivered to the delivery chamber 505 through the extraction pipe 503 and the delivery pipe 504 by the extraction pump 502, and the curing agent is thrown out of the delivery chamber 505 by the rotation of the rotating rod 402;

[0036] 4) Finally, the driving member 401 drives the rotating rod 402 to rotate, and the rotating rod 402 drives the stirring blade 403 to rotate, so as to mix the curing agent with the sludge.

[0037] In summary, the sludge fixative mixing and stirring device can achieve precise adjustment of the height of the mounting plate 2 through the adjustment mechanism 3. This adjustment in turn affects the position of the stirring mechanism 4, so that the stirring blade 403 can be positioned in containers of various heights as needed. This design enables the device to easily solidify the sludge in various containers, and the device can be easily moved to the position where it needs to be used through the universal wheels at the bottom of the movable base 1. It is easy and flexible to use and has a wide range of applications.

[0038] Furthermore, by setting up a curing agent conveying mechanism 5, the curing agent in the curing agent storage box 501 can be conveyed to the feeding chamber 505, and the centrifugal force generated by the rotation of the rotating rod 402 can spread the curing agent out of the rotating rod 402, fully contact with the sludge, and cooperate with the stirring of the stirring blade 403 to accelerate the solidification of the sludge.
