[0029] like Figure 1-5As shown, the present invention proposes a sludge conditioning tank, including a conditioning tank body 12 with its opening facing upwards. An inlet pipe 8 and an outlet pipe 9 are distributed vertically on the side walls of the conditioning tank body 12, both of which are connected to the interior of the conditioning tank body 12. It also includes a fixing plate 13. Side plates 1 are fixedly installed at the center of both sides of the upper edge of the conditioning tank body 12. Connecting plates 2 are provided on both sides of the outer edge of the fixing plate 13. The side of the connecting plates 2 away from the fixing plate 13 is rotatably connected to the corresponding side plate 1 via a stabilizing component 4. Limiting auxiliary components are installed on the outer end faces of both connecting plates 2. 3. Limiting mechanisms 5 that cooperate with limiting auxiliary components 3 are installed on both sides of the upper edge of the conditioning tank body 12; it also includes a stirring shaft 11, a second driving component 7 is installed on the fixed plate 13, one end of the stirring shaft 11 passes through the fixed plate 13 and is drivenly connected to the output end of the second driving component 7, the other end of the stirring shaft 11 does not contact the inner bottom wall of the conditioning tank body 12, and a stirring blade 10 is installed on the outer end face of the stirring shaft 11; a first driving component 6 is installed on the outer wall of the conditioning tank body 12, and the output end of the first driving component 6 is drivenly connected to the corresponding connecting plate 2 through one of the stabilizing components 4.

[0030] In this invention, during the sludge conditioning process, the sludge enters the conditioning tank 12 through the feed pipe 8, then a chemical conditioning agent is added, the second drive assembly 7 is started to drive the stirring shaft 11 to rotate, and the stirring blades 10 stir and condition the sludge. After conditioning is completed, the sludge is discharged through the discharge pipe 9.

[0031] When it is necessary to clean and maintain the preparation tank body 12, the first drive assembly 6 is started first. The first motor 602 drives the connecting rod 401 to rotate through the first gearbox 601. The connecting rod 401 drives the rotating disk 404 to slide on the annular slide rail 402, thereby causing the fixed plate 13 and the stirring shaft 11 to rotate to the outside of the preparation tank body 12.

[0032] Then, the electric push rod 502 in the limiting mechanism 5 is activated. The electric push rod 502 pushes the moving plate 505, and the moving plate 505 drives the limiting block 5010 to be inserted into the limiting groove 301 of the limiting auxiliary component 3.

[0033] At the same time, the photoelectric sensor transmitter 508 and the photoelectric sensor receiver 303 sense each other and confirm that the fixing plate 13 is fixed in place. At this time, the staff can safely enter the conditioning pool 12 to carry out cleaning work.

[0034] After cleaning, reverse the above steps to reset the fixed plate 13 and the stirring shaft 11, and continue the sludge conditioning work.

[0035] In an optional embodiment, the second drive assembly 7 includes a second gearbox 701 and a second motor 702. The second gearbox 701 is fixedly mounted on the fixed plate 13. One end of the stirring shaft 11 passes through the fixed plate 13 and is coaxially connected to the output end of the second gearbox 701. The input end of the second gearbox 701 is drively connected to the output end of the second motor 702.

[0036] It should be noted that by starting the second motor 702 and cooperating with the second gearbox 701, torque amplification and speed regulation are achieved through gear transmission, ensuring that the stirring shaft 11 obtains a stable rotational driving force.

[0037] In an optional embodiment, the stabilizing component 4 includes a connecting rod 401 and a rotating disk 404. One end of the connecting plate 2 away from the fixed plate 13 is fixedly connected to the rotating disk 404. The middle part of the rotating disk 404 away from the fixed plate 13 is rotatably connected to the corresponding side plate 1 through the connecting rod 401. The stabilizing component 4 also includes an annular slide rail 402 and a ring array of sliders 403. The annular slide rail 402 is fixedly installed on the corresponding side plate 1. One end of the ring array of sliders 403 is slidably connected to the groove of the annular slide rail 402, and the other end is fixedly connected to the rotating disk 404. The rotating disk 404, sliders 403, annular slide rail 402 and connecting rod 401 are arranged with the same center.

[0038] It should be noted that when the connecting plate 2 rotates, it can drive the rotating disk 404 to rotate. When the rotating disk 404 rotates, it can drive the connecting rod 401 to rotate on the side plate 1 connected to it, realizing the circular motion of the fixed plate 13. When the rotating disk 404 rotates, it can drive multiple ring array distributed sliders 403 to slide on the groove of the ring slide rail 402 that cooperates with it, ensuring the stability of the connecting plate 2 when it rotates.

[0039] In an optional embodiment, the limiting auxiliary component 3 includes a mounting block 302 and a photoelectric sensor receiving end 303. The mounting block 302 is fixedly mounted on the outer end face of the connecting plate 2 and fixedly connected to the corresponding rotating disk 404. Limiting grooves 301 are formed at both ends of the mounting block 302. The photoelectric sensor receiving end 303 is mounted on the inner wall of the limiting groove 301. The limiting mechanism 5 includes a reinforcing frame 501, an electric push rod 502, a mounting plate 503, a sliding rod 504, a moving plate 505, a limiting plate 506, a sliding sleeve 507, and a limiting block 5010. The mounting plate 503 is fixedly mounted on the upper edge of the conditioning tank body 12, and the reinforcing frame 501 is fixedly mounted on the mounting plate 503. The telescopic shaft of the electric push rod 502 passes through the mounting plate 503 and is fixedly connected to the moving plate 505. A limiting block 5010 that cooperates with the limiting groove 301 is fixedly installed on the moving plate 505. Sliding sleeves 507 are provided on the mounting plate 503 on both the upper and lower sides of the electric push rod 502. The sliding rod 504 slides through the middle of the corresponding sliding sleeve 507. One end of the sliding rod 504 is fixedly connected to the limiting plate 506, and the other end is fixedly connected to the moving plate 505. A slot 509 is opened on the side of the limiting block 5010 near the central axis of the conditioning tank 12. A photoelectric sensor transmitter 508 that cooperates with the photoelectric sensor receiver 303 is installed on the inner wall of the slot 509.

[0040] It should be noted that when the electric push rod 502 in the limit mechanism 5 is activated, the electric push rod 502 pushes the moving plate 505, and the moving plate 505 drives the limit block 5010 to insert into the limit groove 301 of the limit auxiliary component 3; at the same time, the photoelectric sensor transmitter 508 and the photoelectric sensor receiver 303 sense each other to confirm that the fixing plate 13 is fixed in place.

[0041] Furthermore, when the movable plate 505 moves, it can drive the sliding rod 504 to slide within the sliding sleeve 507 connected to it, thus guiding the movable plate 505; and the limiting plate 506 can limit the sliding rod 504, preventing the sliding rod 504 from disengaging from the sliding sleeve 507.

[0042] In an optional embodiment, the side of the mounting plate 503 is fixedly connected to the upper edge of the conditioning tank body 12 by a reinforcing bracket 501.

[0043] It should be noted that the stability between the conditioning tank body 12 and the mounting plate 503 is enhanced by the reinforcement frame 501.

[0044] In an optional embodiment, the first drive assembly 6 includes a first gearbox 601 and a first motor 602. The first motor 602 is fixedly installed on the side wall of the conditioning tank 12, and the first gearbox 601 is fixedly installed on the side of one side plate 1. The output end of the first motor 602 is connected to the input end of the first gearbox 601. The output end of the first gearbox 601 passes through the corresponding side plate 1 and is coaxially connected to the connecting rod 401.

[0045] It should be noted that starting the first motor 602 allows it to engage with the first gearbox 601, which in turn drives the connecting rod 401 connected to it to rotate, thereby controlling the rotation of the fixed plate 13.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
