DETAILED DESCRIPTION

[0023] The utility model is further described below in conjunction with embodiments.

[0024] See also Figure 1-4The utility model provides a device for refining and drying slag powder, including a processing cylinder 1, which also includes a frame 2, which is fixed to the side wall of the bottom end of the processing cylinder 1, and a feeding pipe 3 connected to the inside is fixed to the top side wall of the processing cylinder 1, and a discharge pipe 4 connected to the inside is fixed to the bottom side wall of the processing cylinder 1, and an additional plate 5 is fixed to the inner side wall of the frame 2, and two symmetrically distributed heaters 6 are fixed to the top side wall of the additional plate 5, and the heater 6 is located directly below the processing cylinder 1, and a stirring assembly 7 is arranged on the inside of the processing cylinder 1, and two symmetrically distributed insulation plates 18 are fixed to the outer side wall of the processing cylinder 1. Through the arrangement of the insulation plate 18, the processing cylinder 1 can be kept warm, so that the temperature in the processing cylinder 1 can be kept at a constant temperature, thereby improving the drying processing effect of the slag powder.

[0025] Further Figure 3 and Figure 4 As shown, it is worth specifically explaining that the stirring assembly 7 includes a mounting plate 71, the mounting plate 71 is fixed to a side wall of one side of the processing cylinder 1, a driving motor 72 is fixed to the side wall of one side of the mounting plate 71, a driving shaft 73 is rotatably connected to the inner side wall of the processing cylinder 1, and one end of the driving shaft 73 is coaxially fixed to the output shaft of the driving motor 72; a toothed ring 74, the toothed ring 74 is fixed to the inner side wall of the processing cylinder 1, the toothed ring 74 is meshed with a spur gear 75, a rotating shaft 76 is fastened inside the spur gear 75, and the driving shaft 73 and the rotating shaft 76 are rotatably connected. It is connected to a docking plate 78, and a plurality of stirring rods 77 distributed in a circle are fixed on the outer surface of the rotating shaft 76. The end of the rotating shaft 76 away from the spur gear 75 is slidably connected to the inner side of the processing tube 1. Through the setting of the stirring component 7, the slag micropowder in the processing tube 1 can be evenly stirred, and the slag micropowder can be mixed without dead angles, so that the slag micropowder can be processed more evenly during the drying process, avoiding the rework caused by uneven drying of the slag micropowder. It is more practical and the drying effect of the slag micropowder is improved.

[0026] Further Figure 4 As shown, it is worth explaining in detail that an annular guide groove 8 is opened on the inner side wall of the processing cylinder 1, and one end of the rotating shaft 76 is slidably connected to the inside of the annular guide groove 8. By sliding the rotating shaft 76 in the annular guide groove 8, it can not only play a guiding and limiting role for the rotating shaft 76, but also greatly improve the stability of the rotating shaft 76 during operation.

[0027] The present solution has the following working process: when the slag powder needs to be refined and dried, the handle 17 is first opened manually to make the cover plate 16 flip over after being stressed, and a certain amount of slag powder is poured into the guide hopper 14, and the guide hopper 14 drops into the material box 9, and the driving motor 72 drives the driving shaft 73 to rotate synchronously, and the driven shaft 10 is driven by the transmission effect of the pulley 11 and the belt 12 to rotate synchronously, and the driven shaft 10 is driven to rotate, so that the stirring cage 13 rotates synchronously, and the slag powder in the material box 9 is broken up, and the slag is fed into the material box 9 by the feed pipe 3. The powder is input into the processing tube 1, and the processing tube 1 is continuously heated through the heating conduction effect of the heater 6. The transmission action of the docking plate 78 causes the rotating shaft 76 to rotate around the central axis of the driving shaft 73 after being subjected to force. The meshing transmission action between the spur gear 75 and the toothed ring 74 causes the rotating shaft 76 to rotate while performing a circular motion, driving the stirring rod 77 to rotate synchronously, thereby continuously stirring the slag powder in the processing tube 1, completing the drying process of the slag powder within a certain period of time, and discharging the slag powder to the outside through the discharge pipe 4.

[0028] According to the above working process, it can be known that: through the setting of the stirring component 7, the slag powder in the processing tube 1 can be uniformly stirred, and the slag powder can be mixed without dead angles, so that the slag powder can be processed more evenly during the drying process, avoiding the rework caused by uneven drying of the slag powder, and being more practical. The drying effect of the slag powder is improved, and the transmission action of the pulley 11 and the belt 12 causes the driven shaft 10 to rotate synchronously, and the stirring cage 13 is operated synchronously to break up and differentiate the slag powder in the material box 9, avoiding the adhesion and agglomeration of the slag powder, greatly improving the refinement and drying effect of the slag powder, and also reducing the time of the drying process of the slag powder, completing the drying process of the slag powder in a shorter time, and further improving the drying efficiency of the slag powder.

[0029] Further Figure 4 As shown, it is worth explaining in detail that a material box 9 is arranged directly above the processing cylinder 1, and the material box 9 is connected to the inside of the feed pipe 3, and the inner side wall of the material box 9 is rotatably connected to a driven shaft 10, and a pulley 11 is arranged between the driven shaft 10 and the driving shaft 73. The outer surfaces of the two pulleys 11 are sleeved with belts 12, and the outer surface of the driven shaft 10 is fixed with a stirring cage 13. Through the transmission action of the pulleys 11 and the belts 12, the driven shaft 10 rotates synchronously, and the stirring cage 13 operates synchronously to break up and differentiate the slag powder in the material box 9, avoiding the adhesion and agglomeration of the slag powder, greatly improving the refinement and drying processing effect of the slag powder, and also reducing the aging time of the slag powder drying process, completing the drying process of the slag powder in a shorter time, thereby further improving the drying processing efficiency of the slag powder.

[0030] Further Figure 3 As shown, it is worth explaining in detail that the central axis of the material box 9 is colinear with the central axis of the feed pipe 3, and a guide hopper 14 is fixed to the top side wall of the material box 9. The vertical section of the guide hopper 14 is in the shape of an inverted trapezoid, and the projected area of ​​the guide hopper 14 is larger than the projected area of ​​the material box 9. Through the setting of the guide hopper 14, it can play a role in concentrated material guidance of the slag powder, so that the slag powder is more concentratedly entered into the material box 9 when feeding, thereby improving the processing effect of the slag powder to a certain extent.

[0031] Further Figure 4 As shown, it is worth explaining in detail that an installation frame 15 is fixed to the top side wall of the guide hopper 14, and a cover plate 16 is rotatably connected to the side wall of one side of the installation frame 15, and a handle 17 is fixed to the top side wall of the cover plate 16. Through the setting of the cover plate 16, the material box 9 can be closed, which can avoid splashing when processing slag powder and prevent the waste of slag powder during processing.

[0032] In summary: by the sliding of the rotating shaft 76 in the annular guide groove 8, it can not only play a guiding and limiting role for the rotating shaft 76, but also can greatly improve the stability of the rotating shaft 76 during operation. Through the setting of the guide hopper 14, it can play a role in concentrated material guidance for the slag micropowder, so that the slag micropowder can enter the material box 9 more concentratedly when feeding, which improves the processing effect of the slag micropowder to a certain extent. Through the setting of the cover plate 16, the material box 9 can be closed, which can avoid splashing when processing the slag micropowder and prevent the waste of slag micropowder during processing.
