Abstract
Description
Technical Field
[0001] The invention relates to the technical field of white carbon black processing, in particular to a white carbon black multi-stage wet grinding device and a grinding process thereof. Background Art
[0002] As an important inorganic chemical product, white carbon black is widely used in many fields such as rubber, plastic, coating, ink, etc. As various industries continue to increase their requirements for product performance, more stringent requirements have been put forward for the quality indicators of white carbon black such as particle size distribution, dispersibility and purity.
[0003] In the traditional dry grinding process, due to the lack of liquid medium, a large amount of dust will be generated during the grinding process. The flying dust will also cause material loss and increase production costs. Although simple wet grinding introduces liquid medium and reduces the generation of dust to a certain extent, it usually adopts a single grinding method and grinding equipment, and cannot perform graded grinding according to the characteristics of the material and the difference in particle size. In the grinding process, particles of different particle sizes are simultaneously ground with the same force and method, which is prone to insufficient grinding of large particles and excessive grinding of small particles, resulting in uneven particle size distribution of the product, affecting the performance and quality of the product.

[0017] Beneficial Effects
[0018] The present invention has the following beneficial effects:
[0019] 1. This multi-stage wet grinding device for white carbon black is equipped with a spiral bucket and specific dynamic grinding and static grinding components. The spiral bucket cooperates with the spiral blade on the outer side of the driving shaft to screen the material during the reciprocating up and down movement, so that the material makes a spiral outward diffusion movement on the screen surface to achieve particle stratification. Larger and heavier particles are in the lower layer, and smaller and lighter particles are in the upper layer. Then particles of different particle sizes enter the gap between the dynamic grinding cone and the static grinding circle in an orderly manner for grinding, avoiding the problem of insufficient grinding caused by grinding large and small particles at the same time, and significantly improving the grinding uniformity and product quality.
[0020] 2. Fine grinding and cooling and dust removal: In the static grinding component, water is injected into the water storage chamber through the water inlet pipe. When the water storage chamber is filled with water, the water is ejected through the pressure nozzle under pressure. The water flow flushes the grinding slope, which on the one hand causes the accumulated materials to be washed and rolled, and cooperates with the dynamic grinding component to achieve fine grinding; on the other hand, the water flow cools the grinding part to prevent the high temperature from affecting the equipment and material quality. At the same time, the water flow reduces the floating dust, mixes the dust with water, improves the working environment, and protects the health of the operators.
[0021] 3. Efficient collection and filtration: The collection component is reasonably designed. The ground material flows into the guide cone under the scouring of water flow, and flows into the filter frame through the leakage holes on the inner wall of the guide cone. The filter frame is equipped with at least two sets of removable filter discs, which can efficiently filter the grinding liquid to obtain finely ground and low-water-content white carbon black raw materials. In addition, by controlling the threaded column in the middle of the drive shaft, the centrifugal dehydration or static material removal function of the filter frame can be flexibly realized, which not only improves the collection efficiency, but also facilitates the removal of materials, reducing production costs and production cycles.
[0022] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] See also Figure 1-9The embodiment of the present invention provides a technical solution: a white carbon black multi-stage wet grinding device, comprising a support frame 1, a protective cover 2 is fixedly installed on the inner side of the support frame 1, a grinding cylinder 3 is fixedly installed on the top of the protective cover 2, a water inlet pipe 4 is arranged on the outer side of the grinding cylinder 3, a feed pipe 5 is arranged on the outer side of the grinding cylinder 3 and near the top, a motor bracket 7 is arranged on the outer side of the grinding cylinder 3 and near the top and at the center, and a grinding motor 6 is fixedly installed on the top of the motor bracket 7;
[0036] A spiral bucket 10 is provided on the upper half of the inner wall of the grinding cylinder 3, a static grinding circle 12 is provided on the lower half of the inner wall of the grinding cylinder 3, a circular hole is opened at the bottom of the grinding cylinder 3, a collecting assembly is provided at the bottom end of the grinding cylinder 3, a driving shaft 9 is fixedly installed on the output end of the grinding motor 6, a spiral sheet 8 is provided on the outside of the driving shaft 9, a dynamic grinding assembly is fixedly installed on the outside of the grinding cylinder 3, a static grinding assembly is provided on the inner side of the static grinding circle 12, the dynamic grinding assembly is used in conjunction with the static grinding assembly, the collecting assembly is located below the static grinding assembly, and the spiral bucket 10 is located above the dynamic grinding assembly.
[0037] Specifically, the spiral bucket 10 is spiral-shaped, and a groove is provided on the surface of the spiral bucket 10, wherein the groove is located below the discharge port of the feed pipe 5, and an opening is provided at one end of the spiral bucket 10 close to the dynamic grinding assembly, and the inner ring of the spiral bucket 10 is fitted with the spiral sheet 8 on the outer side of the drive shaft 9.
[0038] In the present embodiment, a spiral bucket 10 is provided to convey the raw material conveyed through the feed pipe 5, namely, the white carbon black raw material to be ground, and to screen it slowly and allow it to enter the grinding section, wherein the screening of the spiral bucket 10 is achieved by the spiral piece 8 on the outside of the drive shaft 9, specifically, the spiral piece 8 is driven to rotate by the rotation of the drive shaft 9. Since the spiral piece 8 is spirally arranged, the spiral piece 8 will squeeze the side of the inner circle of the spiral bucket 10. Since a return spring 11 is provided at the bottom end of the spiral bucket 10, when the spiral piece 8 squeezes the drive shaft 9 to the maximum position, the return spring 11 is in a compressed state. When the spiral piece 8 and the side of the spiral bucket 10 are in a non-squeezed state, the elastic potential energy of the return spring 11 will drive the spiral bucket 10 to move upward. Since the drive shaft 9 is always in motion, the spiral bucket 10 is always in reciprocating up and down motion. At this time, the feed The material discharged from the material pipe 5 falls into the groove opened on the surface of the spiral bucket 10, wherein the spiral bucket 10 performs a spiral involute outward diffusion motion from the inside to the outside on the screen surface during vibration. In this process, the material is relatively concentrated near the center area of the screen surface, and as it gradually diffuses outward, the material distribution gradually becomes sparse, and the material has a certain jumping and stratification phenomenon in the vertical direction. Larger and heavier particles are usually in the lower layer, while smaller and lighter particles are in the upper layer. As the material descends, it will be discharged from the open end of the spiral bucket 10, and under the action of the inclined surface of the dynamic grinding cone 13, the larger particles will enter the gap between the dynamic grinding cone 13 and the static grinding circle 12 along the inclined surface for grinding, and the smaller particles will enter intermittently for grinding, thereby realizing graded grinding and avoiding the problem of insufficient grinding caused by particles of different sizes entering the grinding gap at the same time.
[0039] Specifically, the dynamic grinding assembly includes a dynamic grinding cone 13, a grinding protrusion 18, and a grinding ring 28. The dynamic grinding cone 13 is fixedly mounted on the outside of the driving shaft 9, the grinding ring 28 is fixedly mounted on the outside of the dynamic grinding cone 13, the grinding protrusion 18 is fixedly mounted on the outside of the dynamic grinding cone 13, the grinding protrusion 18 is located below the grinding ring 28, and bumps are equidistantly arranged on the outside of the grinding protrusion 18.
[0040] In this embodiment, a dynamic grinding cone 13 is provided to guide the material and grind the material entering the gap between the dynamic grinding cone 13 and the static grinding ring 12. The grinding protrusion 18 is used in conjunction with the grinding bevel 17 to crush and roll the initially ground material to make it finer. The grinding ring 28 is used to initially crush and roll the material that has just entered the gap. The grinding ring 28 rotates under the drive of the dynamic grinding cone 13 to crush the material. The crushed material falls along the grinding bevel 17 and continues to be ground under the action of the dynamic grinding cone 13. It is accumulated at the grinding protrusion 18 for grinding, and the ground material falls into the guide cone 19 for discharge.
[0041] Specifically, the static grinding assembly includes a static grinding ring 12, a water storage chamber 14, a grinding groove 29, a pressure nozzle 15, and a grinding bevel 17. The static grinding ring 12 is fixedly installed on the inner wall of the grinding cylinder 3, the water storage chamber 14 is opened in the middle of the static grinding ring 12, the grinding groove 29 is opened on the inner side wall of the static grinding ring 12, the grinding bevel 17 is opened on the inner side wall of the static grinding ring 12, and the pressure nozzle 15 is fixedly installed on the inner side wall of the static grinding ring 12. One end of the pressure nozzle 15 is arranged inside the water storage chamber 14, and the other end is located on the inner side of the static grinding ring 12. The conical surface of the dynamic grinding cone 13 forms a gap with the inner wall of the static grinding ring 12.
[0042] In this embodiment, a fascia component is provided for use in conjunction with a dynamic grinding component to achieve fine grinding of materials, wherein a grinding bevel 17 opened in the middle of the static grinding circle 12 is adapted to the conical surface of the dynamic grinding cone 13, and the water storage chamber 14 is connected to the water inlet pipe 4, wherein the water inlet pipe 4 is externally connected to a water pipe, and water is injected into the water storage chamber 14 through the water inlet pipe 4. As the water in the water storage chamber 14 gradually increases, the internal pressure will gradually increase. When the interior is filled with water, water will be sprayed out through the pressure nozzle 15, and the water flow will flush the grinding bevel 17. The water flow will diffuse outward along the surface of the grinding bevel 17 to wash and roll the accumulated materials for grinding, and at the same time cool the grinding part to make the ground materials flow with the water flow, and also reduce floating dust, so that it is mixed with water and enters the guide cone 19 for discharge, wherein the spraying state of the pressure nozzle 15 is triggered by the water pressure injected into the water storage chamber 14.
[0043] Specifically, the collecting assembly includes a guide cone 19, a filter frame 20, a pull rod 21, and a leak hole 27. The guide cone 19 is sleeved on the outside of the driving shaft 9, the filter frame 20 is arranged on the outside of the guide cone 19, the pull rod 21 is fixedly installed on the outside of the filter frame 20, and the leak hole 27 penetrates the inner bottom wall of the guide cone 19, and the leak hole 27 is connected with the filter frame 20;
[0044] A circular hole is provided in the middle of the guide cone 19, and the driving shaft 9 is passed through. An annular groove 25 is provided on the inner wall of the circular hole, and the number of the annular grooves 25 is three groups and is equidistantly distributed around the circumference.
[0045] In this embodiment, the ground material flows into the guide cone 19 along the grinding slope 17 under the scouring of water flow, flows into the filter frame 20 through the leakage hole 27 opened on the inner wall of the guide cone 19, and is filtered through the filter screen arranged in the filter frame 20.
[0046] Specifically, a telescopic cavity 16 is provided in the middle of the driving shaft 9, a mounting hole is provided on the inner wall of the telescopic cavity 16, and a T-shaped block 23 is movably installed on the inner wall of the mounting hole;
[0047] The T-shaped block 23 is arranged horizontally in a T shape, and a positioning spring 24 is arranged on the outer side of the T-shaped block 23. One end of the positioning spring 24 is fixedly connected to the inner wall of the mounting hole, and the other end is fixedly connected to the T-shaped block 23. A chamfer 26 is provided at one end of the T-shaped block 23 close to the telescopic cavity 16.
[0048] A threaded column 22 is movably mounted on the inner wall of the telescopic cavity 16 . The threaded column 22 is provided with threads on the outer side near the bottom end. A threaded groove is provided on the inner wall of the telescopic cavity 16 near the bottom end.
[0049] In this embodiment, a telescopic chamber 16 is provided in the middle of the driving shaft 9 to install the threaded column 22 and the T-shaped block 23, wherein the threaded column 22 can control the lifting length by rotating in the forward and reverse directions to realize the driving of the filter frame 20. It should be noted that the top of the guide cone 19 is movably connected to the inner top wall of the protective cover 2, wherein the top wall of the protective cover 2 is provided with an annular groove, and the annular groove is used to install the guide cone 19 and pull it. When the threaded column 22 moves upward, the top of the threaded column 22 squeezes the guide angle 26 at one end of the T-shaped block 23 to expand outward along the mounting hole and engage with the annular groove 25, so that the driving shaft 9 and the guide cone 19 are connected as one body, so as to drive the filter frame 20 to make a circular motion, and the material gathered in the filter frame 20 throws out the water under the action of centrifugal force;
[0050] Whether the guide cone 19 is connected to the drive shaft 9 as a whole can be controlled by the threaded column 22 before grinding. When the guide cone 19 is separated from the drive shaft 9, the filter frame 20 is in a stationary state, and the drive shaft 9 is in an idling state. Therefore, the material after being ground by the dynamic grinding cone 13 and filtered by the filter frame 20 can be pulled open by pulling the pull rod 21 to pull one side of the filter frame 20, and the ground material can be taken out without affecting the grinding process.
[0051] like Fig. 9 As shown, one side of the filter frame 20 is in an expandable state, and at least two groups of removable filter discs 30 are equidistantly arranged inside the filter frame 20, so as to filter the grinding liquid flowing out through the leakage hole 27 to obtain finely ground raw materials, wherein the filter disc 30 can preferably adopt polyvinylidene fluoride PVDF membrane, which has good chemical stability, corrosion resistance and oxidation resistance, strong hydrophobicity, and is not easily infiltrated by water and general solvents.
[0052] When in use, before the grinding motor 6 is started, the operating state of the collecting component can be controlled by controlling the extension and retraction of the threaded column 22. The specific operation has been described above and will not be repeated here. The raw material to be ground is then discharged through the feed pipe 5 to fall into the spiral bucket 10. The raw material after sorting by the spiral bucket 10 enters the gap between the static grinding circle 12 and the dynamic grinding cone 13 for grinding. The ground liquid raw material enters the filter frame 20 through the guide cone 19 for filtration, thereby obtaining a more delicate white carbon black raw material.
[0053] A multi-stage wet grinding process of white carbon black comprises the following steps:
[0054] S1. Raw material preparation and equipment preparation and commissioning: Pre-treat the white carbon black raw materials to remove impurities to ensure the purity and quality of the raw materials, check whether the various parts of the equipment are firmly installed, and ensure that the structures such as the support frame 1, protective cover 2, and grinding cylinder 3 are stable.
[0055] S2. Raw material screening and preliminary grinding: Start the grinding motor 6, which drives the drive shaft 9 to rotate, and the spiral pieces 8 on the outer side of the drive shaft 9 rotate synchronously to screen the raw materials remaining on the spiral bucket 10.
[0056] S3, fine grinding and flushing and cooling: As the water inside the water storage chamber 14 gradually increases, when the inside is filled with water, the water will be sprayed out through the pressure nozzle 15. The water flow flushes the grinding bevel 17, and the water flow diffuses outward along the surface of the grinding bevel 17, so that the materials accumulated on the grinding bevel 17 are flushed and rolled for fine grinding, and the grinding part is cooled at the same time, reducing the influence of the heat generated during the grinding process on the equipment and materials. The ground materials are mixed with water and flow along the grinding bevel 17 into the guide cone 19 along the water flow.
[0057] S4, collection and filtration: the material and water flowing into the guide cone 19 flow into the filter frame 20 through the leakage hole 27 provided on the inner wall of the guide cone 19. If the filter frame 20 is connected to the drive shaft 9 as a whole, the material gathered in the filter frame 20 will throw out the water under the action of centrifugal force; if the filter frame 20 is in a stationary state, the pull rod 21 can be pulled to open one side of the filter frame 20, and the ground material can be taken out. After multi-stage grinding, the white carbon black is subjected to secondary dehydration, drying and other post-processing processes to obtain the final white carbon black product.

9. A white carbon black multi-stage wet grinding device according to claim 5, characterized in that: A circular hole is provided in the middle of the guide cone (19), through which the drive shaft (9) is arranged, wherein an annular groove (25) is provided on the inner wall of the circular hole, wherein the number of the annular grooves (25) is three groups and is equidistantly distributed around the circumference.
10. A white carbon black multi-stage wet grinding process, applied to a white carbon black multi-stage wet grinding device according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1. Raw material preparation and equipment preparation and commissioning: Pre-treat the white carbon black raw material to remove impurities to ensure the purity and quality of the raw material, check whether the various parts of the equipment are firmly installed, and ensure that the structures such as the support frame (1), the protective cover (2), and the grinding cylinder (3) are stable. S2, raw material screening and preliminary grinding: The grinding motor (6) is started, and the motor drives the driving shaft (9) to rotate, and the spiral sheet (8) on the outer side of the driving shaft (9) rotates synchronously therewith to screen the raw materials remaining on the spiral bucket (10). S3, fine grinding and flushing and cooling: As the water in the water storage chamber (14) gradually increases, when the water is filled inside, the water will be sprayed out through the pressure nozzle (15). The water flow flushes the grinding bevel (17), and the water flow spreads outward along the surface of the grinding bevel (17), so that the materials accumulated on the grinding bevel (17) are flushed and rolled for fine grinding, and the grinding part is cooled at the same time, reducing the influence of the heat generated during the grinding process on the equipment and materials. The ground materials are mixed with water and flow into the guide cone (19) along the grinding bevel (17) along the water flow. S4, collection and filtration: the material and water flowing into the guide cone (19) flow into the filter frame (20) through the leakage hole (27) provided on the inner wall of the guide cone (19). If the filter frame (20) is connected to the drive shaft (9) as a whole, the material collected in the filter frame 20 will throw out the water under the action of centrifugal force; If the filter frame (20) is in a stationary state, the pull rod (21) can be pulled to open one side of the filter frame (20) to take out the ground material. The white carbon black after multi-stage grinding is subjected to secondary dehydration, drying and other post-treatment processes to obtain the final white carbon black product.
