[0030] A feed port 4 is provided on one side of the top of the cover plate 2. The feed port 4 is located on one side of the cover plate 2 and is used to add white carbon black and washing liquid into the equipment.

[0031] The heat-conducting inner cylinder 11 is provided with a plurality of layer plates 20, which are arranged on the upper and lower sides of the stirring rod 10. The heat-conducting inner cylinder 11 is the internal container of the equipment, which is used to contain white carbon and washing liquid. The material of the heat-conducting inner cylinder 11 usually has good thermal conductivity, so that the temperature can be controlled by an external heat exchanger. In addition, the provision of the layer plates 20 increases the contact area between the heat-conducting inner cylinder 11 and the washing liquid, which makes it easier to control the washing temperature through the temperature of the heat-conducting inner cylinder 11 and the second fluid. During the washing process, the main shaft 9 is driven to rotate by the driving motor 3, thereby driving the stirring rod 10 fixed on the main shaft 9 to rotate, so as to stir and wash the white carbon. In this embodiment, a pressure wheel 16 is provided at one end of the stirring rod 10, and the outer wall of the pressure wheel 16 contacts the inner wall of the heat-conducting inner cylinder 11. The pressure wheel 16 is installed at one end of the stirring rod 10 and rotates with the stirring rod 10. The outer wall of the pressure wheel 16 contacts the inner wall of the heat-conducting inner cylinder 11, and pressure is generated by rotation to push the air in the elastic airbag 12 to move. An elastic airbag 12 is provided on the inner wall of the heat-conducting inner cylinder 11, and the elastic airbag 12 is located outside the pressure wheel 16. The elastic airbag 12 is installed on the inner wall of the heat-conducting inner cylinder 11 and outside the pressure wheel 16. When the pressure wheel 16 contacts the elastic airbag 12, the elastic airbag 12 is compressed and the air inside is squeezed.

[0032] A piston cylinder 21 is provided on the outer wall of one side of the elastic airbag 12, and a piston rod 22 is provided inside the piston cylinder 21. The piston cylinder 21 is installed on one side of the elastic airbag 12, and a piston rod 22 is provided inside. The piston cylinder 21 and the piston rod 22 together constitute a pneumatic system for converting the pressure in the elastic airbag 12 into mechanical motion. When the air in the elastic airbag 12 is squeezed, the piston rod 22 is pushed outward, driving the blade 23 to move.

[0033] A rubber sealing sleeve is provided between one end of the piston cylinder 21 and the outer wall of the piston rod 22. The rubber sealing sleeve is installed between one end of the piston cylinder 21 and the outer wall of the piston rod 22 to ensure the air tightness inside the piston cylinder 21 and prevent air leakage. A blade 23 is provided at one end of the piston rod 22. The blade 23 is installed at one end of the piston rod 22.

The return spring 24 is installed on the outside of the piston rod 22, one end of which is fixedly connected to the piston cylinder 21, and the other end of which is fixedly connected to the piston rod 22. When the pressure wheel 16 leaves the elastic airbag 12, the return spring 24 returns to its original state, pulls the piston rod 22 back to its original position, and returns the blade 23 to its initial position, preparing for the next cycle.

[0035] During the washing process, the stirring rod 10 drives the pressure wheel 16 to circulate and roll on the inner wall of the heat-conducting inner cylinder 11. When the pressure wheel 16 contacts the elastic airbag 12, the pressure wheel 16 will generate pressure on the elastic airbag 12, so that the air inside the elastic airbag 12 is pressed toward the piston rod 22, causing the piston rod 22 to move to the side away from the piston cylinder 21. At this time, the return spring 24 is stretched by the force, driving the blade 23 to follow the movement, generating a disturbing stirring effect on the second fluid, promoting the uniform temperature of the second fluid, thereby improving the heat exchange effect; through this design, not only can the washing process of white carbon black be completed efficiently, but also the temperature control during the heat exchange process can be ensured to be more precise and uniform, thereby improving the overall production efficiency and product quality.

[0036] The bottom inner wall of the heat-conducting inner cylinder 11 is provided with a bottom plate 17, which is high in the middle and low around. After washing is completed, the water outlet valve 18 is opened first. Since the bottom plate 17 is high in the middle and low around, the waste water will naturally flow to the water outlet valve 18. The filter on the water outlet valve 18 can effectively block the white carbon black particles to ensure that only the waste water is discharged. The water outlet valve 18 is provided on one side of the bottom of the bottom plate 17, and the discharge valve 19 is provided on the other side. After the washing of the white carbon black is completed, the water outlet valve 18 is opened first. The water outlet valve 18 is provided with a filter, which can allow the waste water after washing to be discharged while the white carbon black remains on the bottom plate 17. When the waste water is discharged, the discharge valve 19 is opened, and the white carbon black in the heat-conducting inner cylinder 11 is discharged one after another in coordination with the rotation of the scraper 25. Through this design, not only can the washing process of the white carbon black be completed efficiently, but also the separation and discharge process of the waste water and the white carbon black after washing can be ensured to be efficient and reliable, thereby improving the overall production efficiency and product quality.

[0037] The outer wall at the bottom of the stirring rod 10 is provided with a scraper 25, and the bottom surface of the scraper 25 is in contact with the top surface of the bottom plate 17. When the stirring rod 10 rotates, the scraper 25 also rotates, pushing the white carbon black on the bottom plate 17 toward the discharge valve 19. The elastic airbag 12 is made of rubber material, and the elastic airbag 12 is inflated. One side of the elastic airbag 12 protrudes from the inner wall of the heat-conducting inner cylinder 11. The elastic airbag 12 is made of rubber material and has good elasticity and durability. The elastic airbag 12 is inflated and filled with air, so that it has certain expansion and elasticity. One side of the elastic airbag 12 protrudes from the inner wall of the heat-conducting inner cylinder 11, which can ensure that the pressure wheel 16 can more effectively contact the elastic airbag 12 when rotating, generating greater pressure.

[0038] In the production process of high-performance white carbon black, when high-performance white carbon black needs to be washed, the device of the present invention is used for heat exchange to help control the temperature of the washing liquid so that it is maintained within a temperature range that is conducive to removing impurities; During the high-performance white carbon black washing process, high-performance white carbon black and washing water are placed in the heat-conducting inner cylinder 11. At this time, the water outlet valve 18 and the material outlet valve 19 are both in a closed state. The first fluid enters and exits through the first water inlet 5 and the first water outlet 6. During the entry and exit process, the first fluid passes through the heat exchange tube 15. The second fluid enters and exits through the second water inlet 7 and the second water outlet 8. The first fluid exchanges heat with the second fluid through the heat exchange tube 15. The second fluid directly contacts the outer wall of the heat-conducting inner cylinder 11. The contact area is large, which is conducive to heat exchange. By controlling the temperature of the second fluid, the washing temperature of the white carbon black is controlled; During the washing process, the main shaft 9 is driven to rotate by the driving motor 3, thereby driving the stirring rod 10 fixed on the main shaft 9 to rotate, and the white carbon black is stirred and washed. During the washing process, the stirring rod 10 drives the pressing wheel 16 to circulate and roll on the inner wall of the heat-conducting inner cylinder 11. When the pressing wheel 16 contacts the elastic airbag 12, the pressing wheel 16 will generate pressure on the elastic airbag 12, so that the air inside the elastic airbag 12 is pressed against the piston rod 22, so that the piston rod 22 moves to the side away from the piston cylinder 21. At this time, the return spring 24 is stretched by force, driving the blade 23 to follow the movement, generating a disturbing stirring effect on the second fluid, promoting the uniform temperature of the second fluid, thereby improving the heat exchange effect; After the washing of the white carbon black is completed, the water outlet valve 18 is opened first. The water outlet valve 18 is provided with a filter screen, which can allow the waste water after washing to be discharged while the white carbon black remains on the bottom plate 17. After the waste water is discharged, the discharge valve 19 is opened, and the white carbon black in the heat-conducting inner cylinder 11 is discharged gradually by cooperating with the rotation of the scraper 25.
