Description

Technical Field

[0001] This invention relates to the field of carbon black granulation and storage technology, and in particular to a carbon black granulation layered drying and storage device and its usage method. Background Technology

[0002] The wet granulation process for carbon black granules involves mixing powdered carbon black with an appropriate amount of water in a granulator, stirring it into spherical granules, and then drying the wet granules to remove water and separate them into qualified products. The wet granulation process is less affected by the structure of carbon black, resulting in high particle strength.

[0003] After granulation, when storing large quantities of carbon black granules, common storage tanks are typically used. This storage method inevitably causes the carbon black granules at the bottom to be subjected to "heavy pressure" from the carbon black granules above, resulting in the direct breakage of many carbon black granules. Even if many carbon black granules do not break directly, they undergo some deformation and show a tendency to break. If severe vibration, compression, or collision occurs during subsequent export and transportation, the carbon black granules will still break.

[0004] To reduce the breakage rate of carbon black granules during storage, the amount (depth) of carbon black granules stored at one time needs to be smaller to reduce the pressure on the granules at the bottom. However, this leads to frequent replacement of storage tanks, reducing the efficiency of the storage tank in the carbon black granule storage and discharge process.

[0005] In summary, after carbon black granulation, the problem that needs to be solved is how to reduce the breakage of carbon black granules while ensuring the efficiency of the storage and discharge processes in the storage tanks. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a carbon black granulation layered drying and storage device and a method of use, thereby reducing the degree of breakage of carbon black granules and ensuring the efficiency of the storage and discharge process of carbon black granules in the storage box.

[0007] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0008] The present invention provides a carbon black granulation layered drying and storage device.

[0011] Multiple plugs are fixedly installed on the vertical rod to seal the material discharge hole.

The vertical length of the upper plug at the upper position is greater than the vertical length of the upper plug at the lower position, and the vertical length of the bottom plug is less than the vertical length of the upper plugs.

[0012] The storage box includes a side mounting plate with multiple sealing rings mounted on it. A connecting plate shaft passes through the sealing rings, and one end of the connecting plate shaft protrudes from the side mounting plate.

[0013] At the material collection station of the storage box: A feed pipe is installed above the storage box, directly opposite the area between the cavity fixing inclined plate and the raised strip plate. A partition rotary drive assembly is installed on the side of the storage box. The feed pipe is equipped with a flow meter. The partition rotary drive assembly is equipped with multiple rotators and a propulsion driver for adjusting the lateral position of the rotators. The output side of the rotators is equipped with a pressing contact end that mates with the side end of the connecting plate shaft of the protruding side mounting plate.

[0014] At the material discharge station of the storage box: An expansion joint for pressing down the top plate is installed above the storage box.

[0015] As a preferred embodiment of the storage device of the present invention: the spacing between adjacent raised strips is the same as the spacing between adjacent cavity fixing inclined plates, wherein each raised strip is independently coplanar with a cavity fixing inclined plate. With the connecting plate pivot as the center of rotation: the raised strips are located at the rotation range of the end of the movable connecting plate.

[0016] As a preferred technical solution of the storage device of the present invention: the end of the movable connecting plate is provided with an end slope, and the raised strip is provided with a strip slope that cooperates with the end slope.

[0017] As a preferred technical solution of the storage device of the present invention: the telescopic device is equipped with a telescopic shaft for pressing down the top plate.

[0018] As a preferred technical solution of the storage device of the present invention: The vertical depth of the feed hole is set to h. A The vertical height dimension of the sealing end is h. C Vertical height h of the sealing end C ≤ Vertical depth of the feed hole is h A According to their positions from lowest to highest: the vertical lengths of the multiple upper plugs are as follows: h1, h2, h3, ... h n ,h1-h C =h2-h1=h3-h2=...=h n -h n-1 .

[0019] As a preferred technical solution of the storage device of the present invention: the bottom plug and the upper plug are provided with insertion slots, the vertical rod is inserted into the insertion slots, the sealing end of the bottom plug and the upper plug are provided with bolt end slots and bolt rod slots, the vertical rod is provided with multiple horizontal screw holes, and bolts are installed at the bolt end slots, bolt rod slots and horizontal screw holes at the same horizontal position.

[0020] As a preferred technical solution of the storage device of the present invention: the push drive is provided with a push shaft facing the storage box, a push frame is installed on the side end of the push shaft, and multiple rotators are installed on the push frame.

[0021] This invention provides a method for using a carbon black granulation, tiered drying, and storage device, comprising the following:

[0022] S1. When the storage box reaches the material collection station, the propulsion driver drives all the rotators to move toward the storage box, so that the extrusion contact end of the rotator makes extrusion contact with the outer end of the connecting plate shaft. All the rotators drive their extrusion contact ends to rotate at least 90°, and all the movable connecting plates in the storage box rotate upward.

[0023] S2. The feeding pipe starts feeding carbon black granules. The flow meter monitors the feeding amount of carbon black granules in real time. Let the storage capacity of each storage cavity be △Q. When the flow meter detects an increase in flow rate of △Q, the rotator at the same horizontal position as the outer end of the lowest position of the movable connecting plate that has been rotated upward rotates in the opposite direction by no less than 90°, which drives the lowest position of the movable connecting plate that has been rotated upward to reset to the position coplanar with the fixed inclined plate of the cavity.

[0024] S3. When all the moving connecting plates are reset to the position coplanar with the fixed inclined plate of the cavity, the flow meter detects that the new flow rate reaches △Q again, the feed pipe stops feeding, and the propulsion driver drives the extrusion contact end of the rotator to separate from the outer end of the connecting plate shaft.

[0025] S4. The storage box leaves the material collection station and arrives at the material discharge station. The discharge port at the bottom of the storage box opens, and after an interval of Δt, the carbon black granules in the lowest storage layer are discharged. The telescopic device then presses down the lifting rod and holds it in place. The initial pressing distance is ΔL1, which is greater than the vertical length of the sealing end of the bottom plug. Then, every interval of Δt, the telescopic device presses down the lifting rod once, with each press increasing the distance by ΔL2. ΔL2 is greater than the vertical length difference between the bottom plug and the lowest upper plug, and ΔL2 is greater than the vertical length difference between adjacent upper plugs.

[0026] S5. After all the carbon black granules in the storage chambers of the storage box are discharged, the telescopic device returns to its original position and separates from the lifting rod. The lifting rod returns to its original position under the action of the tension spring, and the storage box is unloaded.

[0027] Compared with existing technologies, the beneficial effects of this invention are:

[0028] This invention designs a multi-layered inclined partition assembly within the storage box, forming multi-layered storage cavities. It also incorporates movable connecting plates and connecting plate shafts. During material feeding, the movable connecting plates at each layer are rotated and adjusted via a partition rotation drive assembly at the feeding station, ensuring that an appropriate amount of carbon black granules is injected into each storage cavity. Furthermore, the storage box features lifting rods with tension springs and multiple sealing devices. During material discharge, the lifting rods are pressed down in a progressive manner, causing the carbon black granules to be discharged layer by layer from bottom to top. This allows a single storage box to continuously handle large quantities of material storage and discharge, preventing significant breakage of the carbon black granules during storage and transportation, and ensuring the efficiency of the carbon black granule storage and discharge process.

Detailed Implementation

[0038] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0039] Example 1: This invention designs a layered drying and storage device for carbon black granulation with reduced load and large capacity. The main components include a partition assembly, a feeding component, a flow meter, lifting rods and a sealing device, a partition rotation drive assembly, and an expansion joint. The specific structural details are as follows:

[0040] Please see Figure 1 , Figure 2 The storage box 1 has multiple parallel partition components 2 inside. Storage cavity 102 is formed between the bottom partition component 2 and the bottom of the storage box 1, between adjacent partition components 2, and above the top partition component 2. A bottom slope 101 is provided at the bottom of the storage box 1, and a discharge port 106 is provided at the lowest position of the bottom slope 101 of the storage box 1.

[0041] The partition assembly 2 includes a cavity fixing inclined plate 201, which is fixedly connected to the inside of the storage box 1. The high end of the cavity fixing inclined plate 201 is rotatably connected to a movable connecting plate 202. A connecting plate pivot 203 is provided at the connection position between the movable connecting plate 202 and the cavity fixing inclined plate 201. The connecting plate pivot 203 and the movable connecting plate 202 are fixedly connected, that is, when the connecting plate pivot 203 rotates, the movable connecting plate 202 also rotates. Multiple protruding strips 103 are provided on the same inner wall surface of the storage box 1. The multiple protruding strips 103 are directly opposite the high end of the cavity fixing inclined plate 201. The spacing between adjacent protruding strips 103 is the same as the spacing between adjacent cavity fixing inclined plates 201. Each protruding strip 103 is independently coplanar with a cavity fixing inclined plate 201. This coplanarity is not horizontal plane coplanarity, but coplanarity on an inclined plane.

[0042] With the connecting plate pivot 203 as the rotation center: the raised strip 103 is located at the rotation range of the end of the movable connecting plate 202. The end slope 205 is located at the end of the movable connecting plate 202. The raised strip 103 is provided with a strip slope 1031, which cooperates with the end slope 205.

[0043] Please see Figure 1 , Figure 3 The discharge hole 206 is located at the lower end of the cavity fixing inclined plate 201. An inner fixing plate 104 is fixedly installed inside the upper opening of the storage box 1, and the inner fixing plate 104 has a through hole. The lifting rod 5 includes a vertical rod 501, which moves through the inner fixing plate 104 and the discharge hole 206. The lifting rod 5 also includes a top plate 503 located at the top of the vertical rod 501. A tension spring 6 is sleeved on the vertical rod 501 between the top plate 503 and the inner fixing plate 104. Under normal conditions, the tension spring 6 pushes the top plate 503 upward.

[0044] At the material discharge station of storage box 1: Above storage box 1 is an expansion joint 8 for pressing down the top plate 503. The expansion joint 8 is used when discharging material from storage box 1. The expansion joint 8 is equipped with an expansion shaft 801 for pressing down the top plate 503.

[0045] Please see Figure 3 , Figure 4 , Figure 5Multiple plugs 9 are fixedly installed on the vertical rod 501. The plugs 9 are divided into bottom plugs 901 and multiple upper plugs 902. The bottom plugs 901 are fixedly installed at the bottom end of the vertical rod 501. The multiple upper plugs 902 are installed on the vertical rod 501 and located above the bottom plugs 901. The bottom plugs 901 include a plugging end 9011 and a limiting outer ring 9011 located below the plugging end 9011. The limiting outer ring 9011 limits the highest point of the entire lifting rod 5. The plugging end 9011 plugs the material discharge hole 206 at the lowest position. The upper plugs 902 plug the remaining material discharge hole 206. The vertical length of the bottom plugs 901 is less than the vertical length of the upper plugs 902. The vertical length of the upper plugs 902 increases from bottom to top.

[0046] Wherein, the vertical depth of the feed hole 206 is set to h. A The vertical height dimension of the sealing end 9011 is h. C Vertical height h of the sealing end 9011 C ≤The vertical depth of the feed hole is 206 and h A The sealing end 9011 of the bottom plug 901 does not need to be longer than the discharge hole 206; it only needs to block the discharge hole 206.

[0047] In order of increasing position: the vertical lengths of the multiple upper plugs 902 are: h1, h2, h3, ... h n ,h1-h C =h2-h1=h3-h2=...=h n -h n-1 In this way, when pressing down the lifting rod 5, the same height can be pressed down each time, and the pulse signal is the same each time the telescopic device presses down, which simplifies the control program.

[0048] Please see Figure 4 , Figure 5 , Figure 6 Both the bottom plug 901 and the upper plug 902 have insertion slots 903, and the vertical rod 501 passes directly through the insertion slots 903.

[0049] Both the sealing end 9011 of the bottom plug 901 and the upper plug 902 are provided with bolt end grooves 904 and bolt rod grooves 905. The vertical rod 501 is provided with multiple horizontal screw holes 502. After the bolt end grooves 904, bolt rod grooves 905 and horizontal screw holes 502 at the same horizontal position are aligned, the bottom plug 901 or the upper plug 902 can be fixed to the vertical rod 501 by installing bolts.

[0050] Please see Figure 1 , Figure 7 , Figure 8The storage box 1 has a detachable side mounting plate 105, on which multiple sealing rings 204 are mounted. The connecting plate shaft 203 moves through the sealing rings 204 and protrudes out.

[0051] At the material collection station of storage box 1, a discharge pipe 3 is configured above storage box 1. The discharge pipe 3 is equipped with a flow meter 4. The discharge pipe 3 is directly opposite the discharge area between the cavity fixing inclined plate 201 and the raised strip plate 103. The partition rotation drive assembly 7 is located on the side of storage box 1.

[0052] The partition rotation drive assembly 7 includes a propulsion driver 701, which is equipped with a propulsion shaft 702 facing the side mounting plate 105 of the storage box 1. A propulsion frame 703 is mounted on the side end of the propulsion shaft 702, and multiple rotators 704 are mounted on the propulsion frame 703. Each rotator 704 is independently aligned with the outer end of a connecting plate shaft 203. The output side of the rotator 704 is equipped with a pressing contact end 705 that mates with the side end of the connecting plate shaft 203 protruding from the side mounting plate 105. The connecting plate shaft 203 can be made of stainless steel, and the pressing contact end 705 can be made of magnet, so that the two fit together more tightly. The propulsion driver 701 drives the propulsion frame 703 to move forward or backward laterally. When moving forward, the pressing contact end 705 approaches and contacts the outer end of the connecting plate shaft 203. When moving backward, the pressing contact end 705 moves away from the outer end of the connecting plate shaft 203.

[0053] Example 2: This invention designs a method for storing and discharging carbon black granules, the details of which are as follows:

[0054] First, when the storage box 1 reaches the material collection station, the propulsion driver 701 pushes all the rotators 704 toward the storage box 1, so that the pressing contact end 705 of the rotator 704 presses into contact with the outer end of the connecting plate shaft 203. The pressing contact end 705 and the outer end of the connecting plate shaft 203 can be a static friction surface with greater friction.

[0055] Then, all the rotators 704 drive their extrusion contact ends 705 to rotate at least 90°, and all the movable connecting plates 202 inside the storage box 1 rotate upward. At this time, the material discharge channel between the cavity fixing inclined plate 201 and the opposite side plate of the storage box 1 is opened, and the material discharge pipe is directly opposite the vertical material discharge channel of the storage box 1.

[0056] Subsequently, carbon black granulation begins, and the feeding pipe 3 starts feeding carbon black granules. The flow meter 4 monitors the amount of carbon black granules fed in real time. Let the storage capacity of each storage cavity 102 be △Q. Whenever the flow meter 4 detects an increase in flow rate reaching △Q, the rotator 704 at the same horizontal position as the outer end of the lowest position movable connecting plate 202, which has been rotated upwards and opened, rotates in the opposite direction by at least 90°. This causes the lowest position movable connecting plate 202, which has been rotated upwards and opened, to reset to a position coplanar with the cavity fixed inclined plate 201. During this process, the feeding pipe 3 does not need to stop feeding. The designed storage capacity △Q of the storage cavity 102 is not the full load capacity of the storage cavity 102. For example, it can be 90% of the full load capacity to buffer the amount of carbon black granules entering during the reset process of the movable connecting plate 202.

[0057] When all the movable connecting plates 202 are reset to the position coplanar with the cavity fixed inclined plate 201, the flow meter 4 detects that the new flow rate reaches △Q again, the feed pipe 3 stops feeding, and the propulsion driver 701 drives the extrusion contact end 705 of the rotary 704 to separate from the outer end of the connecting plate shaft 203.

[0058] Subsequently, the storage box 1 leaves the material collection station and arrives at the material discharge station: the discharge port 106 at the bottom of the storage box 1 opens, and after an interval of Δt, most of the carbon black granules in the storage cavity 102 are discharged.

[0059] After the carbon black granules in the bottom storage cavity 102 are discharged, the expansion joint 8 presses down the lifting rod 5 and holds it. The initial pressing distance is △L1, which is greater than the vertical length of the sealing end 9011 of the bottom sealing plug 901.

[0060] Then, at each interval △t, the telescopic device 8 presses down on the lifting rod 5 once, and the distance increased by each press is △L2. △L2 is greater than the vertical length difference between the bottom plug 901 and the lowest position upper plug 902, and △L2 is greater than the vertical length difference between adjacent upper plugs 902. In this way, the carbon black granules in the upper storage cavity 102 of the storage box 1 are discharged downward from the discharge hole 206 and finally discharged from the discharge port 106 of the storage box 1.

[0061] Finally, after all the carbon black granules in the storage chambers 102 of the storage box 1 are discharged, the expansion joint 8 returns to its original position and separates from the lifting rod 5. The lifting rod 5 returns to its original position under the action of the tension spring 6. The bottom plug 901 and the upper plug 902 each re-plug the discharge hole 206 at their respective positions. The storage box 1 returns to its empty state and can be used for material storage again.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

When the storage box (1) arrives at the material collection station, the propulsion driver (701) drives all the rotary heads (704) to move toward the storage box (1), so that the pressing contact end (705) of the rotary head (704) presses against the outer end of the connecting plate shaft (203), and all the rotary heads (704) drive their pressing contact end (705) to rotate at least 90°, and all the movable connecting plates (202) in the storage box (1) rotate upward. S2. The feeding pipe (3) starts feeding carbon black granules. The flow meter (4) monitors the amount of carbon black granules fed in real time. Let the storage capacity of each storage cavity (102) be △Q. When the flow meter (4) detects that the new flow reaches △Q, the rotator (704) at the same horizontal position on the outer end of the lowest position of the movable connecting plate (202) that has been rotated upward and opened rotates in the opposite direction by no less than 90°, which drives the lowest position of the movable connecting plate (202) that has been rotated upward and opened to reset to the position coplanar with the cavity fixed inclined plate (201). S3. When all the movable connecting plates (202) are reset to the position coplanar with the cavity fixed inclined plate (201), when the flow meter (4) detects that the new flow reaches △Q again, the feed pipe (3) stops feeding, and the push driver (701) drives the extrusion contact end (705) of the rotary (704) to separate from the outer end of the connecting plate shaft (203); S4. Storage box (1) leaves the material collection station and arrives at the material discharge station; The discharge port (106) at the bottom of the storage box (1) is opened. After an interval of time △t, the carbon black granules in the bottom storage cavity (102) are discharged. The telescopic device (8) presses down the lifting rod (5) and holds it. The distance of the first press is △L1, which is greater than the vertical length of the sealing end (9012) of the bottom sealing plug (901). Then, at each interval △t, the expansion joint (8) presses down on the lifting rod (5) once, and the distance increased by each press is △L2, where △L2 is greater than the vertical length difference between the bottom plug (901) and the lowest position upper plug (902), and △L2 is greater than the vertical length difference between adjacent upper plugs (902). S5. After all the carbon black granules in the storage chambers (102) of the storage box (1) are discharged, the expansion joint (8) returns to its original position and separates from the lifting rod (5). The lifting rod (5) returns to its original position under the action of the tension spring (6), and the storage box (1) is unloaded.
