Description

Technical Field

[0001] The utility model relates to the technical field of paper-plastic production equipment, and particularly relates to a bottom sediment shredding device based on paper-plastic production. Background Technique

[0002] A large amount of bottom sediment is generated during the paper-plastic production process. These bottom sediments can be recycled to reduce losses and save resources. When processing these bottom sediments, shredding treatment is required.

[0003] After retrieval, the patent number CN202322191967.X discloses a bottom sediment shredding device based on paper-plastic production. This solution can realize the crushing and centrifugal filtration of paper-plastic residues by installing a slag shredding mechanism and a centrifugal screening mechanism on the tank body. However, there are certain defects and deficiencies in the use of this solution. First, the centrifugal filtration mechanism and the slag shredding mechanism are separately arranged, and the crushing and centrifugal filtration of paper-plastic residues are realized separately. When in use, the slag shredding mechanism cannot be driven to reciprocate up and down by the centrifugal function, so that the working area of the shredding blades is limited, and the paper-plastic residues cannot be crushed in a large range, and there are easily crushing dead angles. Therefore, improvement is needed. Content of the Utility Model

[0026] Embodiment

[0027] As Figure 1 , Figure 2 and Figure 3As shown in the figure, a bottom-settling slag pulping device based on paper-plastic production proposed by an embodiment of the present utility model includes a tank body 1 and a sealing cover 2 fixedly connected to the top of the tank body 1. It further includes: a centrifugal filter cylinder 8 rotatably connected to a limiting ring 14 fixed on the inner wall of the tank body 1; a toothed ring 9 fixed to the outer wall of the centrifugal filter cylinder 8; a second motor 5 installed on the sealing cover 2, and a driving shaft 12 is coaxially fixed to one side of the second motor 5. The end of the driving shaft 12 extends to the inside of the tank body 1 and is fixed with a gear 13, and the gear 13 meshes with the toothed ring 9; a slag crushing mechanism 4 includes a sealing cylinder 401 adapted to the central cavity of the sealing cover 2, and a circular plate 402 integrally formed on the inner side of the sealing cylinder 401. A rotating rod 409 is rotatably connected to the circular plate 402, and a pulping blade 4010 is fixedly connected to the rotating rod 409. One side of the sealing cylinder 401 is fixedly connected with a support plate 404; a reciprocating lead screw 405 is rotatably connected to the sealing cover 2, and the support plate 404 is adapted to the reciprocating lead screw 405. The bottom of the reciprocating lead screw 405 is fixedly connected with a driven wheel 408, and a driving wheel 11 is fixedly connected to the driving shaft 12. A synchronous belt 10 is arranged between the driving wheel 11 and the driven wheel 408.

[0028] It should be noted that the setting of the limiting ring 14 is used for the rotational limit of the centrifugal filter cylinder 8. The centrifugal filter cylinder 8 is used for the centrifugal screening of the paper-plastic residue after crushing. By fixedly connecting a toothed ring 9 to the upper part of the centrifugal filter cylinder 8, it is used for the rotational drive of the centrifugal filter cylinder 8. By installing a second motor 5 on the sealing cover 2, when the second motor 5 works, it can drive the driving shaft 12 and the gear 13 to rotate. The gear 13 meshes with the toothed ring 9, and then the rotational drive of the centrifugal filter cylinder 8 can be realized. By opening a cavity at the center of the sealing cover 2, it is used for the telescopic displacement of the sealing cylinder 401. The sealing cylinder 401 is adapted to the cavity of the sealing cover 2, and when the sealing cylinder 401 expands and contracts, it can maintain the sealing effect and prevent the slurry from splashing out. By arranging a circular plate 402 on the inner side of the sealing cylinder 401, it is used for the rotational connection of the rotating rod 409. When the rotating rod 409 rotates, it drives the pulping blade 4010 to rotate, and then the crushing treatment of the paper-plastic residue is realized. By arranging a support plate 404 on one side of the sealing cylinder 401, the support plate 404 is adapted to the reciprocating lead screw 405. When the second motor 5 drives the driving shaft 12 to rotate, it can drive the reciprocating lead screw 405 to rotate synchronously through the cooperation relationship among the driving wheel 11, the synchronous belt 10 and the driven wheel 408, and then the support plate 404 and the sealing cylinder 401 are lifted and lowered cyclically, driving the rotating rod 409 and the pulping blade 4010 to lift and lower cyclically, and then expanding the working area of the pulping blade 4010, improving the crushing effect of the paper-plastic residue, and facilitating the recycling of the paper-plastic residue.

The upper end of the limiting rod 407 is fixedly connected with a top plate 406, and the upper end of the reciprocating lead screw 405 is rotatably connected to the top plate 406.

[0030] It should be noted that the setting of the limiting rod 407 can realize the telescopic guiding and limiting functions of the support plate 404, so that the support plate 404 and the sealing cylinder 401 are stably transmitted. The working principle and method of the reciprocating lead screw 405 are known prior arts and will not be elaborated here.

[0031] As Figure 3 shown, in some embodiments, a first motor 403 is installed on the circular plate 402, and the output shaft of the first motor 403 is fixedly connected to the rotating rod 409.

[0032] It should be noted that the first motor 403 can drive the rotating rod 409 and the pulp shredding blades 4010 to rotate, so as to realize the pulverization treatment of the paper-plastic residues inside the tank body 1.

[0033] As Figure 2 and Figure 3 shown, in some embodiments, a limiting frame 4011 is fixedly connected to the inner bottom of the tank body 1, and the rotating rod 409 is fitted on the limiting frame 4011.

[0034] It should be noted that the setting of the limiting frame 4011 can realize the limiting function of the bottom of the rotating rod 409. The bottom of the rotating rod 409 is slidably connected to the hole of the limiting frame 4011 and can rotate during telescoping.

[0035] As Figure 1 and Figure 2 shown, in some embodiments, a feed pipe 3 is communicated with the sealing cover 2, and a drain pipe 6 and a slag discharge pipe 7 are respectively communicated with the bottom of the tank body 1. Valves are installed on both the drain pipe 6 and the slag discharge pipe 7.

[0036] It should be noted that the feed pipe 3 is used for feeding paper-plastic slurry, the drain pipe 6 is used for discharging slurry, and the slag discharge pipe 7 is used for discharging residues.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
