Description

Technical Field

[0001] This utility model relates to the technical field of pulping and flotation light slag machines, specifically a pulping and flotation light slag machine that facilitates slag discharge. Background Technology

[0002] The principle of the flotation light slag machine mainly revolves around the interaction between air bubbles and mineral particles during the flotation process. The flotation light slag machine achieves the separation of light minerals through the interaction between the slurry and air bubbles. It is one of the key pieces of equipment in mining and metallurgical processing. By adjusting the operating parameters and selecting appropriate flotation reagents, the processing effect can be optimized and efficient resource utilization can be achieved.

[0003] Currently, in waste paper pulping production, some companies use flotation light slag machines (apple screens) in their coarse screening systems. The internal structures are basically the same. However, this type of screen does not handle pulp slag well. If the screen pressure is too low (below 150 kPa) or the good pulp valve is opened too wide, a vacuum will be formed inside, which will result in no flow in the top tail slag pipe and the plastic light slag in the pulp cannot be discharged. Therefore, we propose a pulping flotation light slag machine that facilitates slag discharge. Utility Model Content

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] This utility model provides a technical solution: such as Figures 1-4 As shown in this embodiment, a light slag flotation machine for easy slag discharge includes a base 1. A light slag machine housing 2 is fixedly connected to the top of the base 1. The bottom of the light slag machine housing 2 penetrates the base 1. An inlet 4 and a discharge port 21 are provided on the outer side of the light slag machine housing 2, both communicating with the interior of the light slag machine housing 2. A first slag discharge port 3 is provided on the top of the light slag machine housing 2, communicating with the interior of the light slag machine housing 2. An interference strip 12 is fixedly connected to the inner side of the light slag machine housing 2, with a chamfer 19 on one side. A stirring fan blade 14 is rotatably connected between the inner walls of the light slag machine housing 2. An agitator is provided on the outside of the housing 2. The agitator is used to drive the agitator blades 14 to rotate. A foam maker 5 is provided on one side of the base 1. An air inlet pipe 10 is fixedly connected to the output end of the foam maker 5. The bottom of the light slag machine housing 2 is provided with a slurry outlet 6, an air inlet 8, and a second slag discharge outlet 9. The slurry outlet 6, the air inlet 8, and the second slag discharge outlet 9 are all connected to the interior of the light slag machine housing 2. A slurry outlet pipe 7 is fixedly connected to the bottom end of the slurry outlet 6. The air inlet 8 is fixedly connected to one end of the air inlet pipe 10. The slurry outlet pipe 7 and the air inlet pipe 10 are respectively connected to the interior of the slurry outlet 6 and the air inlet 8. A solid-liquid separation plate 15 is fixedly connected between the inner walls of the light slag machine housing 2.

[0023] When removing slag from the light slag flotation machine, the slurry is first injected into the interior of the light slag flotation machine housing 2 on the base 1 through the slurry inlet 4. Then, the flotation reagent is injected into the interior of the light slag flotation machine housing 2 through the discharge port 21. Next, the stirring assembly drives the stirring fan blades 14 to rotate between the inner walls of the light slag flotation machine housing 2, so that the slurry and flotation reagent are fully mixed. Then, the foaming machine 5 injects air into the interior of the light slag flotation machine housing 2 through the air inlet pipe 10 and the air inlet 8, so as to generate bubbles. At the same time, under the action of the interference bar 12 and the chamfer 19, the bubbles carry the light slag to the surface and are discharged through the first slag discharge port 3, while the heavy slag is separated by the solid-liquid separation plate 15 and slides down to the second slag discharge port 9 for discharge. Finally, the separated good slurry is discharged through the slurry outlet 6 and the slurry outlet pipe 7, thereby improving the slag removal efficiency and quality of the light slag flotation machine.

[0024] like Figures 1-4 As shown, the stirring assembly includes a rotating rod 13, which is rotatably connected to the inner wall of the light slag machine housing 2. The outer side of the rotating rod 13 is fixedly connected to the stirring blade 14. A connecting shaft 20 is rotatably connected to the outer side of the light slag machine housing 2. One end of the connecting shaft 20 extends into the interior of the light slag machine housing 2 and is fixedly connected to the rotating rod 13. A worm gear 17 is fixedly connected to one end of the connecting shaft 20. A mounting plate 16 is fixedly connected to the outer side of the light slag machine housing 2. A worm 18 is rotatably connected to one side of the mounting plate 16. The worm 18 meshes with the worm gear 17. A stirring motor 11 is fixedly mounted on one side of the mounting plate 16. The output end of the stirring motor 11 passes through the mounting plate 16 and is fixedly connected to the worm 18.

[0025] The stirring motor 11 drives the worm gear 18 to rotate on one side of the mounting plate 16, which causes the worm wheel 17 to drive the connecting shaft 20 to rotate on the outside of the light slag flotation machine housing 2, and causes the rotating rod 13 to drive the stirring fan blades 14 to rotate between the inner walls of the light slag flotation machine housing 2, thereby further improving the flotation efficiency of the light slag flotation machine.

[0026] This utility model provides a pulping flotation light slag remover that facilitates slag removal. The specific working principle is as follows: When removing slag in the pulping flotation light slag remover, the slurry is first injected into the interior of the light slag remover housing 2 on the base 1 through the slurry inlet 4. Then, the flotation reagent is injected into the interior of the light slag remover housing 2 through the discharge outlet 21. Next, the stirring motor 11 drives the worm gear 18 to rotate on one side of the mounting plate 16, causing the worm wheel 17 to drive the connecting shaft 20 to rotate on the outside of the light slag remover housing 2. This, in turn, causes the rotating rod 13 to drive the stirring fan blades 14 within the light slag remover. The rotation between the inner walls of the shell 2 allows the slurry and flotation reagents to mix thoroughly. Subsequently, the foaming machine 5 injects air into the interior of the light slag machine shell 2 through the air inlet pipe 10 and the air inlet 8, generating bubbles. At the same time, under the action of the interference bar 12 and the chamfer 19, the bubbles carry the light slag to the surface and are discharged through the first slag discharge port 3, while the heavy slag is separated by the solid-liquid separation plate 15 and slides down to the second slag discharge port 9 for discharge. Finally, the separated good slurry is discharged through the slurry outlet 6 and the slurry outlet pipe 7, thus completing the slag removal work of the slurry.
