[0071] The lifting stirring mechanism includes a lifting stirring piece 29 and a matching assembly 28 fixed centrally on the bottom wall of the stirring tank 11.

[0072] The matching assembly 28 is an annular seat 281 fixed centrally on the bottom wall of the stirring tank 11, and arc grooves 282 are arranged at equal intervals on the upper end of the annular seat 281.

[0073] Lifting stirring part 29 includes several groups of lifting ring seat 291 distributed up and down on the shaft 30, the fan-shaped lifting plate 293 fixed by the protruding arm 292 with equal interval distribution outside the lifting ring seat 291, and the roller 296 movably installed by the support arm 295 at the lower end of the lowermost lifting ring seat 291, the fan-shaped lifting plate 293 is located between the adjacent stirring plate 325;

[0074] The roller 296 is in contact with the upper end surface of the annular seat 281;

[0075] The vertical plate 294 is used to connect and fix between the adjacent lifting ring seat 291 up and down;

[0076] The uppermost lifting ring seat 291 is penetrated by the T-shaped vertical rod 324 with equal interval distribution, and the T-shaped vertical rod 324 is fixed at the lower end of the inner fixed disc 322.

[0077] The servo motor 10 is fixed on the top of the stirring tank 11 by the support 27, and the output end of the shaft 30 extends into the tank, and is connected with the rotating stirring mechanism 32 and the lifting stirring mechanism:

[0078] The rotating stirring mechanism 32 is directly fixed on the shaft 30 and rotates synchronously with the shaft;

[0079] The lifting stirring mechanism converts the rotary motion into lifting motion through the cooperation of the roller 296 and the annular seat 281;

[0080] The filter pressing assembly 31 is indirectly driven by the rotating stirring mechanism through the meshing of the gear 313 and the inner tooth ring 321.

[0081] Working principle of the rotating stirring mechanism 32:

[0082] The core of the rotating stirring mechanism 32 is the inner fixed disc 322 and the stirring plate 325:

[0083] Rotary drive: the servo motor 10 drives the shaft 30 to rotate, the inner fixed disc 322 rotates synchronously with the shaft, and the inner tooth ring 321 and the stirring plate 325 are driven to revolve around the shaft through the connecting arm 323.

[0084] Stirring action: the stirring plate 325 performs circumferential stirring on the release agent during rotation, so that vortex flow is generated; the liquid flow channel 326 on the stirring plate 325 forms up and down convection during stirring, enhancing the mixing effect.

[0085] Working principle of the lifting stirring mechanism:

[0086] The lifting stirring mechanism converts the rotary motion into vertical lifting through the mechanical structure of the roller-arc groove:

[0087] Structural cooperation: the lifting ring seat 291 is connected with the inner fixed disc 322 through the T-shaped vertical rod 324, and can slide up and down along the rotating shaft 30; the lowest lifting ring seat 291 is connected with the roller 296 through the supporting arm 295, and the roller 296 is in contact with the arc-shaped groove 282 of the annular seat 281.

[0088] Motion conversion: when the rotating shaft 30 rotates, the lifting ring seat 291 rotates synchronously with the inner fixed disc 322, and the roller 296 rolls in the arc-shaped groove 282; the ups and downs of the arc-shaped groove 282 force the roller 296 to drive the entire lifting stirring part 29 to make periodic lifting motion; the adjacent lifting ring seats 291 are connected through the vertical plate 294 to ensure synchronous lifting.

[0089] Stirring effect:

[0090] The fan-shaped lifting plate 293 performs axial stirring on the release agent during the lifting process, breaks the horizontal vortex flow, and forms three-dimensional mixing;

[0091] The lifting motion makes the bottom sediment be lifted, improving the uniformity of solid-liquid mixing.

[0092] Linkage working principle of filter pressing assembly:

[0093] The filter pressing assembly 31 realizes independent screw filter pressing through gear transmission 313:

[0094] Power transmission: when the inner tooth ring 321 rotates with the rotating stirring mechanism, it drives the gear 313 meshing with it to rotate; the gear 313 is fixed at the bottom of the rotating rod 312, which drives the rotating rod 312 and the filter pressing spiral blade 311 to rotate.

[0095] Filter pressing process:

[0096] When the filter pressing spiral blade 311 rotates, it performs axial extrusion on the release agent in the second filter screen barrel 9; liquid seeps out through the mesh holes of the second filter screen barrel 9, and solid impurities are intercepted and gathered to the bottom of the barrel; the propelling action of the spiral blade makes the impurities be compressed, improving the solid-liquid separation efficiency.

[0097] Synergistic working process:

[0098] Starting stage:

[0099] The servo motor 10 is started, the rotating shaft 30 drives the rotating stirring mechanism 32 to rotate, and at the same time, through the linkage of the lifting stirring mechanism and the filter pressing assembly, the three actions of "circumferential stirring + axial lifting + spiral filter pressing" are realized.

[0100] Mixing stage:

[0101] The stirring plate 325 and the fan-shaped lifting plate 293 work together to make the recovered release agent and the new mother liquor fully mixed;

[0102] The filter assembly continuously filters impurities to ensure the purity of the mixed solution.

[0103] The other end of the bottom of the collecting tank 18 is communicated with a spraying device, and the demolding agent temporary storage pressure tank 14 of the spraying device is communicated with the stirring tank 11.

[0104] The bottom of the stirring tank 11 is connected to the bottom of the demolding agent temporary storage pressure tank 14 through a third pipeline 24, and a second conveying pump 12 is arranged on the third pipeline 24, and the second conveying pump 12 is electrically connected with the PLC controller.

[0105] The demolding agent temporary storage pressure tank 14 is used to introduce the demolding agent into the spray nozzle 16 inside the collecting tank 18, and the demolding agent sprays the pipe pile mold 21.

[0106] The spraying device further comprises a spraying pipe 23 connected to the bottom of the demolding agent temporary storage pressure tank 14 and a first pneumatic valve 17 arranged on the spraying pipe 23, and the first pneumatic valve 17 is electrically connected with the PLC controller.

[0107] The spraying pipe 23 extends into the inside of the collecting tank 18 and is communicated with the spray nozzle 16.

[0108] The demolding agent temporary storage pressure tank 14 is connected with a fourth pipeline 25, and a second pneumatic valve 13 is arranged on the fourth pipeline 25, and the second pneumatic valve 13 and the air pump are electrically connected with the PLC controller. The PLC controller controls the second pneumatic valve 13 to be opened, the PLC controller controls the air pump to work to introduce high-pressure air into the demolding agent temporary storage pressure tank 14, so that the demolding agent in the demolding agent temporary storage pressure tank 14 enters the spraying pipe 23 under the pressure of the air pressure.

[0109] Specifically, in use, the pipe pile mold 21 is conveyed into the demolding agent spraying chamber by the chain plate machine 15, the photoelectric switch 22 senses and starts the spraying device, the demolding agent in the demolding agent temporary storage pressure tank 14 enters the spraying pipe 23 through the air pressure, and is sprayed out at high speed through the spray nozzle 16, and is sprayed in the inner cavity of the mold;

[0110] When the pipe pile mold 21 leaves the spraying chamber, the photoelectric switch 22 is closed, the demolding agent stops spraying, and the demolding agent spraying operation is completed.

[0111] During spraying, the splashed demolding agent and the excess demolding agent in the inner cavity of the bottom of the pipe pile mold 21 will drip and gather into the collecting tank 18 arranged below the spraying chamber, and the collecting tank 18 is arranged obliquely to facilitate the self-flow of the demolding agent, and then the demolding agent is uniformly recycled into the recycling pool 5.

[0112] The first filter screen barrel 2 (the filter hole is 100-200 meshes) is arranged in the recycling pool 5, wherein the bottom of the first filter screen barrel 2 is 30-80 cm away from the bottom wall of the recycling pool 5, so that the gathered demolding agent can be precipitated and preliminarily isolated from impurities.

[0113] When the liquid level sensor 4 detects that the amount of the release agent to be recycled in the recycling tank 5 reaches a certain amount, it sends a signal to the PLC controller, which triggers the submersible pump 3 switch again to deliver the recycled release agent in the recycling tank 5 to the mixing tank 11;

[0114] The second filter basket 9 (filter hole 100-200 mesh) is arranged at the top of the inside of the mixing tank 11 to isolate the condensate and floating matter in the second filter basket 9;

[0115] The timing start servo motor 10 is used to stir the release agent in the mixing tank 11 to mix the release agent and water uniformly.

[0116] When the release agent in the temporary storage pressure tank 14 is used up, the PLC controller starts the first delivery pump 7 to pump the fresh release agent in the release agent mother liquor tank 6 to the mixing tank 11, and starts the servo motor 10. After the release agent is stirred uniformly by the stirring assembly, clean water is added according to the proportioning requirement, and the mixture is stirred again.

[0117] After the mixture of the release agent and water is detected to be qualified, the PLC controller controls the second delivery pump 12 to work to pump the stirred release agent to the release agent temporary storage pressure tank 14 for standby. Thus, the next cycle is entered.

[0118] The recycled release agent cannot be used as fresh release agent mother liquor for water mixing and stirring, and needs to be reduced in the water mixing proportion. It can be used only after passing the workshop inspection.

[0119] Although the embodiments of the present application have been shown and described, it is understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
