[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-6A device for processing waste materials from the production of household paper includes a base plate 1. A stirring tank 2 is disposed on one side of the top of the base plate 1, and a solid-liquid separation tank 3 is disposed on the other side of the top. The stirring tank 2 and the solid-liquid separation tank 3 are connected by a guide pipe 14. The top of the stirring tank 2 is open, and a cover plate 4 is disposed at the opening. The cover plate 4 can be removed from the stirring tank 2 for convenient maintenance of related components. A stirring motor 5 is installed on the top of the cover plate 4. The power output shaft of the stirring motor 5 extends through the interior of the stirring tank 2 and is connected to a stirring device. The components include: a support frame 7 fixed at the top of the base plate 1 and near the solid-liquid separation tank 3; a hydraulic cylinder 8 mounted on the support frame 7; a pressure plate 9 fixed to the power output shaft of the hydraulic cylinder 8 by bolts; the pressure plate 9 can be removed from the power output shaft of the hydraulic cylinder 8 for easy cleaning; a push plate 11 driven by a hydraulic cylinder 10 is provided inside the solid-liquid separation tank 3; filter holes 1102 are evenly distributed on the push plate 11; and filter holes 301 are evenly distributed on the inner bottom wall of the solid-liquid separation tank 3.

[0026] Please see Figure 2 and Figure 6 In this embodiment, the stirring assembly includes a stirring rod 501, stirring blades 12, and cutting blades 13 that are fixedly connected to the power output shaft of the stirring motor 5. The stirring blades 12 are fixed at equal distances on the stirring rod 501, and the cutting blades 13 are fixed at equal distances on the stirring rod 501 and located between the stirring blades 12.

[0027] Specifically, the stirring blade 12 can agitate the waste paper inside the mixing tank 2, making it move and mix better with the liquid inside. One side of the cutting blade 13 has a sharp blade, which can continuously cut the waste paper it comes into contact with, making it easier to break up the waste paper and helping it to form pulp better.

[0028] Please see Figure 2 In this embodiment, the bottom of the stirring tank 2 is designed to be inclined. One end of the guide pipe 14 is fixedly connected to the bottom of the stirring tank 2, and the other end of the guide pipe 14 is inclined and connected to the side wall of the solid-liquid separation tank 3. A ball valve 15 is also installed on the pipe body of the guide pipe 14.

[0029] Specifically, the bottom of the mixing tank 2 is designed to be inclined, which facilitates the flow of pulp and allows it to enter the solid-liquid separation tank 3 through the guide pipe 14. A ball valve 15 is installed on the guide pipe 14 to close the guide pipe 14, preventing the liquid inside the mixing tank 2 from entering the solid-liquid separation tank 3.

[0030] Please see Figure 2 and Figure 3In this embodiment, hydraulic cylinder 2 10 is installed on the top of the base plate 1. The power output shaft of hydraulic cylinder 2 10 moves through the solid-liquid separation tank 3 and is fixed with a fixing plate 1001. The fixing plate 1001 is fixedly connected to the push plate 11 by multiple bolts.

[0031] Specifically, the push plate 11 is detachably fixed to the fixing plate 1001 by bolts, which makes it easy to separate the push plate 11 from the power output shaft of the hydraulic cylinder 2 10 and to clean the push plate 11.

[0032] Please see Figure 2 and Figure 3 In this embodiment, an annular liquid collection chamber 17 is provided on the inner bottom wall of the solid-liquid separation tank 3 at a position corresponding to the filter hole 301. The bottom of the solid-liquid separation tank 3 is fixed with outlet pipes 18 that are connected to the liquid collection chamber 17 in an annular shape at equal intervals. The liquid outlet ends of multiple outlet pipes 18 are connected to a circular pipe 19. A drain pipe 20 is connected to one side of the bottom of the circular pipe 19. A valve is provided on the drain pipe 20.

[0033] Specifically, the liquid collection chamber 17 is used to collect the liquid flowing out from the filter hole 301. The liquid is then introduced into the circular tube 19 and finally discharged through the drain pipe 20. The drain pipe 20 has a valve, which can be used with the solid-liquid separation tank 3 depending on the situation. The valve can be kept open. When pulp is input from the mixing tank 2, the liquid can be discharged directly. Alternatively, the valve can be opened to discharge the liquid after all the pulp in the mixing tank 2 has been introduced into the solid-liquid separation tank 3.

[0034] Please see Figure 3 , Figure 4 and Figure 5 In this embodiment, a raised frustum 1101 is fixed at the center of the top of the push plate 11. The size of the push plate 11 is the same as that of the pressure plate 9. The side wall of the push plate 11 slides against the inner wall of the solid-liquid separation tank 3. The multiple filter holes 1102 on the push plate 11 correspond one-to-one with the multiple filter holes 301 on the solid-liquid separation tank 3. A filter screen 1103 is also placed on the top of the push plate 11. The filter screen 1103 has a hole in the middle to facilitate the passage of the raised frustum 1101.

[0035] Specifically, the raised frustum 1101 facilitates the flow of liquid near the center of the push plate 11, while the second filter hole 1102 corresponds to the first filter hole 301, allowing the filtered liquid to directly enter the collection chamber 17 for easy and unified discharge. The filter screen 1103 installed on the push plate 11 can filter the pulp and liquid in the pulp, and the filter screen 1103 can be removed from the push plate 11 for easy cleaning later.

[0036] Please see Figure 1 and Figure 2In this embodiment, a feed inlet 6 is provided on the top side of the cover plate 4, and an air hole is provided on the top of the pressure plate 9. An electric heating tube 16 is installed in a ring shape inside the side wall of the solid-liquid separation tank 3. The electric heating tube 16 is connected to the mains power through a wire.

[0037] Specifically, the feed inlet 6 facilitates the entry of materials. After the pressure plate 9 has finished squeezing the pulp in the solid-liquid separation tank 3, the steam generated by the opening of the electric heating tube 16 can be discharged through the air hole, which can be connected to a pipe to discharge the steam.

[0038] In use, waste materials generated during the production of household paper products such as facial tissues and toilet paper are fed into the mixing tank 2 through the feed inlet 6, and an appropriate amount of water is added. Bleaching agent or alkali solution is added as needed. Then, the mixing motor 5 is started. The power output shaft of the mixing motor 5 drives the mixing rod 501, the mixing blade 12, and the cutting blade 13 to rotate, thereby agitating the soft waste materials of facial tissues or toilet paper inside the mixing tank 2. The mixing blade 12 agitates the paper, causing it to move, and the cutting blade 13 continuously cuts the paper it comes into contact with, thereby breaking the paper. Finally, the paper can be mixed with water in the mixing tank 2 to form pulp. Water can soften the fibers and promote pulp formation, bleaching agent can bleach the pulp, and alkali solution can remove impurities, promote fiber separation, and improve pulp performance.

[0039] After the waste material forms pulp in the mixing tank 2, the ball valve 15 can be opened. The pulp in the mixing tank 2 is guided by the guide pipe 14 to be transported to the solid-liquid separation tank 3 for solid-liquid separation. The valve on the drain pipe 20 is opened. The solid is intercepted by the filter screen 1103 on the push plate 11. The water falls through the filter hole 2 1102 and the filter hole 1 301 and enters the liquid collection chamber 17. Then it is discharged through the outlet pipe 18, the circular pipe 19 and the drain pipe 20.

[0040] After the pulp in the solid-liquid separation tank 3 has been naturally filtered for a period of time, the hydraulic cylinder 8 can be activated. The power output shaft of the hydraulic cylinder 8 pushes the pressure plate 9 down and into the solid-liquid separation tank 3, thereby further squeezing the paper cake formed in the solid-liquid separation tank 3, thereby further squeezing out the water in the paper cake. Then the electric heating tube 16 can be activated to heat the paper cake in the solid-liquid separation tank 3, thereby further evaporating the water in the paper cake, and the steam is discharged from the air hole.

[0041] Finally, hydraulic cylinder 210 can be activated, and its power output shaft pushes push plate 11 to rise. Push plate 11 pushes the paper cake formed on its top to rise and protrude from solid-liquid separation tank 3, making it convenient for workers to remove the compressed and dried paper cake from solid-liquid separation tank 3.

[0042] In summary, this processing device can crush, mix and form pulp from waste materials in the mixing tank 2, and can separate solids and liquids and dry them into cakes in the solid-liquid separation tank 3. The coordination between the equipment is more seamless, which can improve the processing efficiency of waste materials for tissue paper production.

[0043] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
