[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Reference Figure 1-4A pulp mixing device for processing household paper includes a pulp mixing tank 1, a lifting pipe 4 is provided on one side of the middle part of the pulp mixing tank 1, a pulp pump 6 is provided on one side of the lifting pipe 4, and the top of the lifting pipe 4 is connected to the blanking port 7, and the blanking port 7 is connected to the inside of the pulp mixing tank 1. A plurality of screens 9 are rotatably installed on the middle part of the pulp mixing tank 1 through a rotating seat 8. A tooth groove wall 92 is provided on the outside of the screen 9 and is connected to a drive motor 51 through gear transmission. The drive motor 51 is installed in a drive box 5.

[0022] Furthermore, a feed pipe 3 is installed on one side of the upper portion of the mixing tank 1 , the feed pipe 3 is connected to the interior of the mixing tank 1 , and the bottom of the mixing tank 1 is connected to the interior of the base 2 , and a discharge pipe 31 is provided on one side of the base 2 .

[0023] Furthermore, a plurality of drive motors 51 are installed inside the drive box 5, and the output end of the drive motor 51 is connected to the drive gear 52, one side of the drive gear 52 is connected to the driven gear 53 through tooth groove engagement, and one side of the driven gear 53 is connected to the screen 9 through tooth groove engagement.

[0024] Furthermore, a tooth groove wall 92 is provided on the outer side of the screen 9 , and the tooth groove wall 92 is meshed and connected with the driven gear 53 , thereby realizing power transmission of the drive motor 51 .

[0025] Furthermore, dynamic sealing rings 91 are provided on the upper and lower outer walls of the screen 9, and the dynamic sealing rings 91 are limitedly installed in the installation groove 81 opened on the inner wall of the rotating seat 8, thereby ensuring its stability and sealing during operation.

[0026] Furthermore, the driven gear 53 is rotatably mounted at the connection between the driving box 5 and the slurry mixing tank 1 , and two sides of the driven gear 53 are respectively engaged with the tooth groove wall 92 and the driving gear 52 .

[0027] Furthermore, the inlet flow channel of the pulp pump 6 is connected to the interior of the base body 2 through the connecting pipe 61 , and the outlet flow channel of the pulp pump 6 is connected to the discharge pipe 31 .

[0028] In this embodiment, the processed pulp is fed into the tank body of the mixing tank 1 through the feed pipe 3. At this time, the pulp pump 6 is in operation, and the pulp that falls inside the seat body 2 is extracted through the connecting pipe 61, and pumped into the lifting pipe 4 connected thereto. The lifting pipe 4 is connected to the drop port 7, so that the pulp falls freely from the drop port 7, and under the influence of gravity, collides with the multiple screens 9 provided inside the mixing tank 1. At this time, the pulp is sheared and dispersed by the screens 9, and then falls into the seat body 2 again.

[0029] Among them, a tooth groove wall 92 is provided on the outside of the screen 9. Under the action of the driving motor 51, the driving motor 51 drives the driven gear 53 set in the middle of the mixing tank 1 to rotate through the driving gear 52. The driven gear 53 drives the tooth groove wall 92 connected thereto, that is, the screen 9 to rotate, and then when it contacts the pulp, it rotates to improve the passability and dispersion effect of the pulp and avoid pulp accumulation.

[0030] Among them, during actual use, the pulp dispersed by the screen 9 falls into the seat body 2 and collides with the existing pulp, thereby forming a certain turbulence. In this process, the pulp collides, shears, mixes, and disperses with each other, thereby dispersing and mixing the pulp fibers. Under the extraction action of the pump body, the pulp is repeatedly mixed to meet the processing requirements.

[0031] In actual use, the mounting groove 91 provided inside the rotating seat 8 fits with the dynamic sealing ring 81 to ensure sealing.

[0032] In the present invention, the pulp is pumped to the drop port by the pulp pump 6, and collides with multiple screens 9 during the pulp falling process. At the same time, the rotating screens 9 are used to disperse the pulp in the process, and the dispersion and fusion processes are repeated in the base 2, which helps to further break up the flocs in the pulp, making its fibers more dispersed and uniform, effectively improving the mixing effect of the pulp, and ensuring the processing quality.

[0033] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
