DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solution and advantages of the utility model more clear, the solid-liquid mixing device of the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0032] like Figure 1As shown, a solid-liquid mixing device is used to mix liquid raw materials (such as liquid additives) and solid particle raw materials (such as elastomer particles), including: a shell 1, a driving device 2, a liquid inlet funnel 3 and a liquid inlet pipe 4. The shell 1 has an inner cavity 5 with a cylindrical shape and an axis extending in the vertical direction. The bottom end of the inner cavity 5 is in a closed state, and the top end has an opening 6 for allowing solid particle raw materials to enter the inner cavity 5. The liquid inlet funnel 3 can be rotatably connected to a position corresponding to the opening 6 outside the inner cavity 5. The top end of the liquid inlet funnel 3 is an open end 7, and the bottom end is a closed end 8. A drainage hole 9 is provided on the closed end 8. One end of the liquid inlet pipe 4 is connected to the drainage hole 9, and the other end is located in the inner cavity 5, so that the liquid raw material can enter the liquid inlet funnel 3 through the open end 7, and then flow into the inner cavity 5 through the liquid inlet pipe 4. The driving device 2 is fixedly connected to the shell 1 and is transmission-connected to the liquid inlet funnel 3 to drive the liquid inlet funnel 3 to drive the liquid inlet pipe 4 to rotate in the inner cavity 5. In actual use, the operator can input the solid particle raw material into the inner cavity 5 through the opening 6, and the solid particle raw material can be dispersed in the horizontal direction after entering the inner cavity 5. At the same time, the operator can input the liquid raw material into the liquid inlet funnel 3 from the open end 7 of the liquid inlet funnel 3, and the liquid raw material entering the liquid inlet funnel 3 can pass through the drainage hole 9 and enter the inner cavity 5 through the liquid inlet pipe 4 by gravity to mix with the solid particle raw material located in the inner cavity 5. While the liquid raw material enters the inner cavity 5 through the liquid inlet pipe 4, the driving device 2 drives the liquid inlet funnel 3 to drive the liquid inlet pipe 4 to rotate in the inner cavity 5. At this time, one end of the liquid inlet pipe 4 located in the inner cavity 5 will change its position in the inner cavity 5 under the rotation of the liquid inlet pipe 4, so as to achieve the purpose of discharging the liquid raw material to different positions in the inner cavity 5, thereby improving the mixing effect of the liquid raw material and the solid particle raw material in a dispersed state.

[0033] In actual production, Figure 1As shown, the liquid discharge hole 9 includes a first through hole 10, a second through hole 11, ..., and an Nth through hole (not shown in the figure), wherein N is an integer greater than 1, and the liquid inlet pipe 4 includes a first tube body 12, a second tube body 13, ..., and an Nth tube body. The first tube body 12 is connected to the first through hole 10, the second tube body 13 is connected to the second through hole 11, ..., and the Nth tube body is connected to the Nth through hole, and one end of the first tube body 12 located in the inner cavity 5, one end of the second tube body 13 located in the inner cavity 5, ..., and one end of the Nth tube body located in the inner cavity 5 are sequentially arranged in intervals along the radial direction of the inner cavity 5. Further, the number of first through holes 10 is at least two, the number of first tube bodies 12 is equal to the number of first through holes 10, and they correspond one to one, and at least two ends of the first tube bodies 12 located in the inner cavity 5 are arranged in sequence along the circumference of the inner cavity 5; the number of second through holes 11 is at least two, the number of second tube bodies 13 is equal to the number of second through holes 11, and they correspond one to one, and at least two ends of the second tube bodies 13 located in the inner cavity 5 are arranged in sequence along the circumference of the inner cavity 5; ...; the number of N-th through holes is at least two, the number of N-th tube bodies is equal to the number of N-th through holes, and they correspond one to one, and at least two ends of the N-th tube bodies located in the inner cavity 5 are arranged in sequence along the circumference of the inner cavity 5. The use of such a technical solution can make the liquid raw material entering the inner cavity 5 more dispersed and uniform in the inner cavity 5.

[0034] As an implementation method, Figure 1 As shown, the driving device 2 includes a driving motor 14 and a driving shaft 15; the driving motor 14 is fixedly connected to the bottom of the housing 1, and a mounting through hole 16 with an axis extending in the vertical direction is provided on the bottom wall of the inner cavity 5, the driving shaft 15 is passed through the mounting through hole 16 and the axis coincides with the axis of the mounting through hole 16, the bottom end of the driving shaft 15 is connected to the driving motor 14, and the top end is located at a position horizontal to the opening 6, and the liquid inlet funnel 3 is fixedly connected to the top end of the driving shaft 15, so that the driving motor 14 can drive the liquid inlet funnel 3 to rotate relative to the housing 1 through the driving shaft 15. It should be noted that in the horizontal direction, there is a distance between the end of the liquid inlet pipe 4 located in the inner cavity 5 and the axis of the driving shaft 15.

[0035] Specifically, Figure 2 As shown, the drive shaft 15 further includes a sealing member 17, which is disposed between the outer wall of the drive shaft 15 and the inner wall of the mounting hole 16 to seal the gap between the outer wall of the drive shaft 15 and the inner wall of the mounting hole 16. The sealing member 17 may be an O-ring (but not limited to this) sleeved on the drive shaft 15. Figure 2As shown in the figure, a positioning groove 18 extending along the circumference of the mounting through hole 16 is provided on the inner wall of the mounting through hole 16, and the O-type sealing ring is at least partially located in the positioning groove 18. In this way, the O-type sealing ring can be installed firmly and prevented from coming out of the gap between the outer wall of the drive shaft 15 and the inner wall of the mounting through hole 16.

[0036] As an implementation method, Figure 1 As shown, it also includes an upper stirring blade 19, and the inner cavity 5 includes a falling cavity 20 and a deposition cavity 21 arranged in sequence from top to bottom and interconnected with each other. The end of the liquid inlet pipe 4 away from the discharge hole 9 is located at the top of the falling cavity 20, so that the liquid raw material discharged from the liquid inlet pipe 4 can fall downward in the falling cavity 20 to the deposition cavity 21 under the action of gravity, and the solid particle raw material enters the falling cavity 20 from the opening 6, and falls downward in the falling cavity 20 to the deposition cavity 21 under the action of gravity. The upper stirring blade 19 is located in the falling cavity 20 and is fixedly connected to the driving shaft 15. The driving motor 14 drives the upper stirring blade 19 to rotate in the falling cavity 20 through the driving shaft 15 to stir the liquid raw material and the solid particle raw material falling downward in the falling cavity 20. In this way, the liquid raw material and the solid particle raw material can be mixed in the process of falling, thereby improving the mixing effect. Furthermore, it also includes a lower stirring blade 22, which is located in the deposition chamber 21 and fixedly connected to the drive shaft 15. The drive motor 14 drives the lower stirring blade 22 to rotate in the deposition chamber 21 through the drive shaft 15 to stir the liquid raw material and solid particle raw material entering the deposition chamber 21 to further improve the mixing effect.

[0037] It should be noted that if Figure 1 As shown in the figure, the shape of the falling chamber 20 is a cylinder whose axis coincides with the axis of the driving shaft 15, the shape of the deposition chamber 21 is a truncated cone whose axis coincides with the axis of the driving shaft 15 and tapers downward, and the shape of the lower stirring blade 22 matches the shape of the deposition chamber 21. Further, as shown in the figure, a discharge hole 23 is provided on the side wall of the deposition chamber 21, so that the liquid raw material and the solid particle raw material entering the deposition chamber 21 can be discharged from the discharge hole 23 to the outside of the shell 1 after mixing. In actual work, the lower stirring blade 22 can not only stir the liquid raw material and the solid particle raw material entering the deposition chamber 21, but also drive the mixed liquid raw material and the solid particle raw material to be discharged from the discharge hole 23 to the outside of the shell 1. In specific production, it can be as follows Figure 1 The device shown in the figure includes a discharge pipe 24 , one end of which is connected to the discharge hole 23 , and the other end of which extends to an external target location, so that the mixed material discharged from the discharge hole 23 can be transported to the external target location through the discharge pipe 24 .

Therefore, the protection scope of the utility model patent shall be based on the attached claims.
