It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0029] Please refer to Figure 1 、 Figure 2 and Figure 3 The present utility model provides a waste recycling device for color paste production, including a separation and filtration box 1 to avoid the influence of external factors when the color paste waste is inside. A control panel 2 is installed on the outside of the separation and filtration box 1 to facilitate the operation of the device by staff. A feed inlet 3 penetrating the inside is provided at the top of the separation and filtration box 1, and multiple feed inlets 3 can be set to speed up the blanking speed. Inside the separation and filtration box 1, a screening chamber, a mixing chamber, and a filtration chamber are sequentially arranged from top to bottom to achieve three - stage treatment of the color paste waste and perform different filtration and screening operations. A lower box door 7 is installed on the outside of the separation and filtration box 1 at the filtration chamber, so that the filter layer 110 can be taken out through the lower box door 7 for cleaning, and the situation of blockage of the second screening mesh 19 can be avoided.

[0030] A pull-out shell 6 that can be pulled outwards is provided between the screening chamber and the mixing chamber. The pull-out shell 6 is installed inside between the screening chamber and the mixing chamber through a mounting step, so that the pull-out shell 6 can be supported by force. And a first screening mesh 9 is provided inside the pull-out shell 6 to screen out large impurities in the color paste waste, making the screening and recycling effect better. And the inside of the screening chamber is set to be circular to facilitate the agitation of the stirring blades 11, reducing the situation of the color paste waste adhering to the inner wall of the screening chamber. And the first screening mesh 9 is arranged in a downward semi-circular shape, so that when the first screening mesh 9 avoids blocking the stirring blades 11, it is also convenient to store the screened large impurities inside it. When the pull-out shell 6 is pulled out, the color paste waste inside can be cleaned. The first rotating shaft 10 is connected to the inside of the screening chamber through a bearing. Stirring blades 11 are symmetrically arranged on the outer side of the first rotating shaft 10. A first motor 4 is installed on the outer side of the separation and filtration box 1 and is connected to the first rotating shaft 10. The first motor 4 drives the first rotating shaft 10 to make the stirring blades 11 rotate, and the stirring blades 11 drive the color paste waste inside to agitate, thereby accelerating the screening speed of the first screening mesh 9 and avoiding the situation of blocking the first screening mesh 9. Moreover, under the action of the wide stirring blades 11, the contact area with the color paste waste is strengthened, making the stirring effect better.

[0031] A partition 15 is provided between the mixing chamber and the filtration chamber to separate them, preventing the mixed slurry waste from directly entering the filtration chamber and deteriorating the screening effect. One end on the outer side of the mixing chamber is provided with a water inlet 12 so that water can be input into the filtration chamber to mix with the waste after the first screening, making the separation effect better when the mixed waste is screened. A downwardly penetrating falling port 16 is provided at the side end of the partition 15, and the falling port 16 is located at the top of the second screening mesh 19. And a solenoid valve 17 is installed inside the falling port 16 to prevent the falling situation when mixing with water, making the mixing effect better. And the second rotating shaft 13 is connected to the inside of the mixing chamber through a bearing. A plurality of stirring rods 14 are symmetrically arranged on the outer side of the second rotating shaft 13. A second motor 5 is installed on the outer side of the separation and filtration box 1 and is connected to the second rotating shaft 13. The second motor 5 drives the second rotating shaft 13 to make the stirring rods 14 mix the slurry waste inside the mixing chamber, accelerating the mixing efficiency and making the work progress faster.

[0032] A second screening mesh 19 that is inclined to one side is provided at the upper end inside the filtration chamber. The inclination downward enables the waste to flow from top to bottom, and the waste is subjected to a second screening operation during the flowing process. And a discharge port 18 is provided on the outer side of the separation and filtration box 1 at the bottom end of the second screening mesh 19, so that the screened impurities are discharged from the discharge port 18 to avoid accumulation. A filter layer 110 is installed at the lower end of the second screening mesh 19. The liquid screened by the second screening mesh 19 is filtered through the filter layer 110, so that the water is filtered out for recycling, making the waste recycling effect better. And a water outlet is provided on one side of the filtration chamber to discharge the filtered water.

[0033] Preferably, a water pump 111 is installed outside the separation filter box 1 through a mounting box 8. The water suction end of the water pump 111 penetrates through the bottom of the filtering cavity, and the output end of the water pump 111 is connected to a water delivery pipe 112. The other end of the water delivery pipe 112 is connected to the water inlet 12 through a three-way pipe. Under the action of the water pump 111, the filtered water is pumped out and input into the water inlet 12 through the water delivery pipe 112, so that the water is recycled, thereby achieving the purpose of saving water resources.

[0034] Working principle: When in use, first connect the control panel 2, the first motor 4, the second motor 5, the solenoid valve 17 and the water pump 111 to an external power supply. Then input the waste material into the separation filter box 1 through the feed inlet 3 and place it on the first screening mesh 9. The first motor 4 drives the first rotating shaft 10 to make the stirring blades 11 stir the internal waste material, so that the screening effect of the waste material under the action of the first screening mesh 9 is better. Then the screened waste material falls onto the partition plate 15, and water is input into it through the water inlet 12. The second motor 5 drives the second rotating shaft 13 to mix it through the stirring rod 14. Moreover, after the solenoid valve 17 at the lower end of the falling port 16 is opened, the mixed waste material can flow downward on the second screening mesh 19, and the waste material is filtered and screened again during the flowing process. The screened impurities are discharged through the discharge port 18, and the liquid flows downward and is filtered again by the lower filter layer 110. After the water falls to the lower end of the filter layer 110, it can be recycled under the action of the water pump 111, thus completing the work.
