[0002] In the process of paper production, a large amount of wastewater will be generated. The printing and dyeing wastewater discharged from the paper mill contains not only harmful chemical inorganic substances, but also volatile phenols, precipitated solids, suspended matter, lignin and other organic matter. After the wastewater is left to stand, a large amount of precipitation will appear, which is also a part of the papermaking wastewater that needs to be treated.

[0003] A papermaking wastewater sedimentation and recovery device disclosed in the Chinese patent application publication specification CN220385876U includes a base, an upper end surface of the base is fixedly connected with a mixing sedimentation device and a sewage purifier, the mixing sedimentation device includes a shell, a sedimentation box is installed inside the shell, the upper end surface of the shell is fixedly connected with a driving motor, the output end of the driving motor is fixedly connected with a stirring rod, the stirring rod penetrates the outer wall of the shell and extends to the inside of the sedimentation box, and the outer wall is fixedly connected with two vortex blades, the upper end surface of the shell is fixedly connected with a water injection port, one end of the water injection port extends to the inside of the sedimentation box, after mixing is completed, it is stationary and waits for sedimentation, after sedimentation is completed, the electronic valve in the drain pipe is opened, and under the action of the filter screen, the wastewater is discharged into the sewage purifier through the drain pipe for purification, and discharged from the outlet pipe after purification, and the filtered sediment residue is discharged from the discharge port through the discharge port and the discharge pipe for recycling.

[0004] After the sedimentation is completed, the staff needs to wait for the wastewater in the sedimentation box to be completely discharged before opening the baffle to remove the sediment on the filter, which wastes a lot of time. In addition, the staff needs to remove the sediment on the filter from the narrow discharge port, which is troublesome to operate. When the wastewater and the agent are stirred by a single stirring device, the wastewater and the agent will rotate unidirectionally with the stirring blades, resulting in slow mixing efficiency, thereby reducing the working efficiency of the device. Utility Model Content

[0005] The utility model provides a papermaking wastewater sedimentation recovery device for papermaking to solve the problems in the prior art that wastewater cannot be discharged and sediment cannot be taken out at the same time, the operation of workers in taking out sediment is more troublesome, and the mixing efficiency of wastewater and reagent is slow, thereby reducing the working efficiency of the device.

[0006] The utility model is implemented through the following technical scheme: a papermaking wastewater sedimentation and recovery device for papermaking, comprising a sedimentation tank, a lifting mechanism is arranged outside the sedimentation tank, the lifting mechanism comprises a lifting plate, two support plates are fixed to the outer surface of the sedimentation tank, a hydraulic telescopic rod is fixed to the upper surface of each of the support plates, the extended end of each of the hydraulic telescopic rods is fixed to the lifting plate, two fixing rods are fixed to the bottom surface of the lifting plate, a lifting block is fixed to the bottom end of each of the fixing rods, a transverse groove is opened inside each of the lifting blocks, a collecting drawer is arranged below the lifting plate, a filter screen is arranged at the bottom of the collecting drawer, a stirring mechanism is arranged inside the sedimentation tank, the stirring mechanism comprises a motor, and the motor is fixed to the bottom surface of the lifting plate.

[0007] Specifically, two strip blocks are fixed on the outer surface of the collecting drawer, and each of the strip blocks is slidably connected to the corresponding transverse groove. By sliding the strip blocks into the transverse grooves, the lifting blocks can drive the collecting drawer to rise and fall. When disassembling the collecting drawer, the collecting drawer can be disassembled by pulling the collecting drawer to make the strip blocks slide out of the transverse grooves.

[0008] Specifically, two sliding grooves are provided inside the sedimentation tank, each of which is slidably connected to a corresponding lifting block. The lifting block slides along the inner wall of the sliding groove when lifting. The sliding groove, in cooperation with the transverse groove, can limit the strip block, thereby ensuring the stability of the lifting of the collection bin.

[0009] Specifically, a stirring rod 1 is fixed to the output end of the motor, a connecting rod is fixed to the outer surface of the stirring rod 1, and a circular sleeve is fixed to the outer surface of the connecting rod. The motor can drive the circular sleeve to perform circular motion along the axis of the stirring rod 1 while driving the stirring rod 1 to rotate.

[0010] Specifically, the upper surface of the circular sleeve is rotatably connected to the gear, and the bottom surface of the gear is fixed with a stirring rod 2. The circular sleeve can drive the gear and the stirring rod 2 to make circular motion together, and the upper end of the stirring rod 2 passes through the inside of the circular sleeve and is fixed to the bottom surface of the gear, so that the gear can drive the stirring rod 2 to rotate inside the circular sleeve.

[0011] Specifically, a fixed gear ring is fixed to the bottom surface of the lifting plate, and the fixed gear ring is meshed with the outer surface of the gear. When the circular sleeve drives the gear to make a circular motion, the gear is always meshed with the fixed gear ring, so that the gear rotates while making a circular motion, thereby driving the stirring rod 2 to rotate.

[0013] The utility model provides a papermaking wastewater sedimentation recovery device for papermaking, which has the following beneficial effects:

[0014] 1. The papermaking wastewater sedimentation and recovery device for papermaking is provided with components such as a lifting mechanism. After the sedimentation is completed, the drain pipe is opened to discharge the wastewater. At the same time, the hydraulic telescopic rod is controlled to drive the lifting plate to rise, so that the lifting block drives the collecting bin to rise. The filter screen at the bottom of the collecting bin can filter and separate the sediment, thereby separating the sediment inside the collecting bin. After the collecting bin rises to the top of the sedimentation tank with the sediment, the collecting bin is removed from the lifting block, and the staff can take out the sediment in the collecting bin, and then reinstall the collecting bin in the lifting block, and then drive the collecting bin to descend to the bottom of the sedimentation tank through the hydraulic telescopic rod. After the wastewater in the sedimentation tank is drained, the drain pipe is closed, and the wastewater can be precipitated and recovered again. The operation is convenient and the working efficiency of the device is improved.

[0015] 2. The papermaking wastewater sedimentation and recovery device for papermaking is provided with a stirring mechanism. After the papermaking wastewater and the reagent are poured into the sedimentation tank, the stirring rod 1 is driven to rotate by a motor. When the stirring rod 1 rotates, the circular sleeve and the gear make a circular motion. Under the action of the fixed gear ring, the gear will rotate when making a circular motion, so that the stirring rod 2 can make a circular motion inside the sedimentation tank when stirring the wastewater, thereby increasing the stirring range of the device. When the two stirring rods rotate, the wastewater forms two vortices, and the contact parts of the vortices flow relatively. The wastewater collides with each other, so that the liquid medicine in the wastewater is fully mixed with the wastewater, which greatly improves the reaction speed between the reagent and the wastewater, and improves the wastewater sedimentation efficiency.
