Description

Technical Field

[0001] This invention relates to the field of carbon black manufacturing technology, specifically to a drying device for manufacturing highly dispersed nanocomposite carbon black. Background Technology

[0002] Carbon black is a functional filler with a nanostructure and is widely used in industries such as rubber, plastics, and coatings. However, due to the large specific surface area of ​​carbon black particles, they are very easy to aggregate, making it difficult to achieve uniform dispersion in polymer matrices or organic solvents. Improving the dispersibility of carbon black in polymer matrices or organic solvents and the compatibility between dispersion media, and giving carbon black high added value.

[0003] To improve the dispersion of carbon black in polymer matrices, the commonly used modification method is surface grafting modification. This method uses small organic molecules with low molecular weight and bifunctionality, grafting one end of the molecule onto the surface of carbon black and filling it into a polymer that is immiscible with the other end. By utilizing the aggregation effect of the ungrafted end, nano-carbon black particle chains are formed in the polymer matrix, thereby improving the dispersibility of carbon black.

[0004] In existing technologies, organic compounds are usually mixed with carbon black and in-situ grafted modification is carried out using methods such as heating, ultrasound, mechanical shearing, and supercritical fluid extraction. The subsequent products all need to be dried at high temperatures to obtain the finished product. In industrial production, high-temperature drying is usually used to ensure continuous production in order to achieve rapid evaporation of moisture and increase yield. However, for some heat-sensitive small molecules, high temperatures can cause the small molecules to decompose, affecting their modification performance. Furthermore, the decomposed substances are prone to corroding drying equipment and causing metal impurity contamination, which cannot guarantee the performance requirements of modified carbon black.

[0033] The present invention provides the following embodiments.

[0034] Example 1

[0035] This invention provides a drying apparatus for manufacturing highly dispersed nanocomposite carbon black, such as... Figure 1 As shown, the device includes a vacuum drying unit body 8, with a spray device connected inside the vacuum drying unit body 8. The vacuum drying unit body 8 is connected to a dust collector bag filter 12 via a vacuum pipe. The dust collector bag filter 12 prevents dust extracted from the furnace from entering the vacuum pump and evacuates the air inside the furnace before material is introduced, so that the furnace body is under a certain negative pressure. The vacuum pressure system is used to regulate the internal pressure of the furnace body and stabilize the vacuum degree inside the drying furnace. The vacuum pressure system connected to the vacuum pump is also used to regulate the internal pressure of the furnace body and stabilize the vacuum degree inside the drying furnace.

[0036] The vacuum drying device body 8 includes a drying furnace body 801. A pressure sensor, a temperature sensor, and an online moisture analyzer 15 are located inside the drying furnace body 801. The drying furnace body 801 is inclined at a 2-5° angle from the feed end to the discharge end. Multiple sets of lifting plates 20 are installed on the inner wall of the drying furnace body 801, with a height of 50mm-70mm, to ensure that the carbon black is heated fully and evenly during the reaction process, improving drying efficiency. A pressure control system and a temperature sensor are installed on the outer wall of the end cap. The pressure control system controls the pressure inside the drying furnace body, maintaining a certain vacuum level inside the furnace. The temperature sensor monitors the actual temperature at the front end of the furnace. The online moisture analyzer is used to test the water content of the material at the rear end of the furnace body online.

[0037] The outer wall of the drying furnace body 801 is provided with a high-temperature plate heating layer group, a medium-temperature plate heating layer group, and a low-temperature plate heating layer group. The high-temperature plate heating layer group includes a high-temperature shell 901, which is connected to a high-temperature electric heating system 902. The medium-temperature plate heating layer group includes a medium-temperature shell 1001, which is connected to a medium-temperature electric heating system 1002. The low-temperature plate heating layer group includes a low-temperature shell 1101, which is connected to a low-temperature electric heating system 1102. The drying furnace body 801 is equipped with heat-conducting devices (which may be heat-conducting pipes), and the high-temperature shell 901, medium-temperature shell 1001, and low-temperature shell 1101 are respectively connected to these heat-conducting devices. The temperature control range for the high-temperature plate heating layer group is 0~180℃, the temperature control range for the medium-temperature plate heating layer group is 0~140℃, and the temperature control range for the low-temperature plate heating layer group is 0~80℃.

[0038] The vacuum drying device body 8 has a discharge port 16 at its rear end, located at the bottom of the rear end of the drying furnace body 801. The discharge port 16 is sealed with a slide gate valve; the slide gate valve is opened during discharge and closed during vacuum drying. The drying furnace body 801 also has a sealing system at the connection between the front cover 19 and the rear cover 18. The sealing system includes a compression spring and a sealing ring. An inflation capsule 14 is installed inside the sealing ring, which, when inflated, effectively ensures the vacuum level of the furnace body. The end cover and the furnace body are fastened with positioning bolts, making the sealing mechanism more robust. The compression spring and the inflation capsule 14 are connected to the sealing ring on the side connecting to the front cover 19 or the rear cover 18. When subjected to external pressure, the compression spring's extension and contraction gives the sealing ring a certain degree of flexibility, reducing wear. The inflation capsule inside the sealing ring effectively ensures the vacuum level of the furnace body when inflated.

[0039] The working principle of the above technical solution is as follows:

[0040] In this embodiment, a liquid-phase composite method is used to coat and modify carbon black to achieve uniform mixing at the molecular and atomic levels. This method is easy to control the reaction and facilitates the addition of other components. The mixed slurry is then sprayed into the vacuum drying device body 8 through a spraying device for segmented drying. Based on the integrated feeding and discharging linkage mechanism of liquid-phase composite and vacuum drying, not only can the high quality and high efficiency of material drying be guaranteed, but also the continuity of industrial production can be ensured.

[0041] The beneficial effects of the above technical solution are as follows:

[0042] 1. By using multiple sets of lifting plates 20 on the inner wall of the drying furnace body 801, the carbon black can be heated fully and evenly during the reaction process, thereby improving the dispersibility of the carbon black;

[0043] 2. The drying furnace body 801 is inclined at an angle of 2-5° from the feed end to the discharge end. This design helps the flowability of carbon black during the drying process, thereby improving the drying efficiency.

[0044] 3. The temperature range within the drying furnace body 801 is controlled by the high-temperature plate heating layer group, the medium-temperature plate heating layer group, and the low-temperature plate heating layer group. The temperature of the high-temperature, medium-temperature, and low-temperature zones can be adjusted separately as needed to meet different drying requirements.

[0045] 4. The sealing system, including the compression spring, sealing ring and gas-filled capsule 14, can effectively ensure the vacuum level of the drying oven body 801, ensuring that it will not be disturbed by external gases during the drying process, thereby improving the sealing performance. At the same time, the extension and contraction of the compression spring gives the sealing ring a certain degree of flexibility, which can reduce the wear of the sealing ring.

[0046] 5. The drying furnace body 801 is equipped with heat-conducting devices, which are respectively connected to the high-temperature shell 901, the medium-temperature shell 1001 and the low-temperature shell 1101. These heat-conducting devices help to evenly transfer heat to all parts of the drying furnace body 801 and improve the heat conduction performance.

[0047] In summary, the apparatus of this embodiment can provide highly dispersible nanocomposite carbon black manufacturing, improve drying efficiency, achieve temperature control, and has good sealing and thermal conductivity, thereby effectively producing high-quality nanocomposite carbon black products.

[0048] This invention addresses the issues raised in the background art by improving drying efficiency and using three different drying temperatures. These issues include the common practice in industrial production of using high-temperature drying to rapidly evaporate moisture and increase yield, but for some heat-sensitive small molecules, high temperatures can cause decomposition, affecting their modification properties. Furthermore, the decomposed substances can corrode drying equipment, causing metal contamination and failing to guarantee the performance requirements of modified carbon black.

[0050] Based on Example 1, such as Figure 1 As shown,

[0051] The discharge port of the pulping device 3 is connected to the spraying device through the first liquid pipe 51. The pulping device 3 includes a pulping cylinder 2 and a stirring device 4, and the stirring device 4 is connected to the pulping cylinder 2.

[0052] The spraying device includes several atomizers 7. The feed pump 6 has its feed end and discharge end connected to the first liquid pipe 51 and the second liquid pipe 52, respectively. The discharge end of the second liquid pipe 52 is connected to the atomizer 7.

[0053] Preferably, the pulping cylinder 2 and the top cover 201 are detachably connected, the feeding port 202 is located on one side of the top cover 201, and the observation port 203 is located on one side of the top cover 201; the pulping cylinder 2 and the top cover 201 are fastened together by bolts and sealed by a sealing ring; the feeding port is located on one side of the top cover 201 for feeding materials, and an end cap is provided on the feeding port.

[0054] The stirring device 4 includes a stirring motor 1, which is located outside the top cover 201 and connected to a stirring shaft 401 via a coupling. The portion of the stirring shaft 401 located inside the pulping cylinder 2 is connected to stirring blades 402 and shearing blades 403 at intervals. The upper layer consists of stirring blades, and the lower layer consists of a set of thickened, serrated shearing blades, with at least three blades for stirring materials and the shearing blades for crushing materials. These two sets of stirrers are detachable and replaceable.

[0055] The vacuum drying device body 8 also includes a transmission device 21, which includes a gear ring 2101, which is rigidly connected to the outside of the drying furnace body 801; the gear ring 2101 meshes with a drive gear 2102; the drive gear 2102 is connected to a drive motor 2103 through a transmission shaft and a coupling.

[0056] The beneficial effects of the above technical solution are as follows:

[0057] 1. The pulping device 3 is used to make the raw materials into a pulp, and is connected to the spraying device through the first liquid pipe 51. The spraying device includes an atomizer 7 and a feed pump 6. The raw materials are sent into the atomizer for spraying through the first liquid pipe 51 and the second liquid pipe 52. Such a spraying device can atomize the material into small particles evenly, which increases the heat transfer area between the material and the drying furnace and improves the drying efficiency.

[0058] 2. The stirring device 4 includes a stirring motor 1 and a stirring shaft 401, which are connected by a coupling. The stirring shaft 401 is equipped with stirring blades 402 and shearing blades 403. The stirring blades 402 are used to stir the materials, and the shearing blades 403 are used to crush the materials. This design can effectively mix and crush the materials, improve the uniformity of the materials and the reaction efficiency.

[0059] 3. The transmission device 21 is installed on the outside of the drying furnace body 801. Through the gear ring 2101, drive gear 2102, transmission shaft and drive motor 2103, the rotation of the drying furnace body 801 is realized. This can make the drying furnace body maintain a stable rotation speed during operation, ensure that the material is heated evenly and improve the drying effect.

[0060] In summary, the drying device of this embodiment, through the combination of a pulping device, a stirring device, a spraying device, and a transmission device, can achieve pulping, uniform atomization, and efficient drying of raw materials, while maintaining the stable rotation of the drying furnace, thereby improving drying efficiency and product quality.

[0064] A first support ring 715 and a second support ring 720 are fixedly installed in the atomizing chamber 703 on the side away from the impeller chamber 702. The sides of the first support ring 715 and the second support ring 720 away from the impeller chamber 702 are rigidly connected to the hemispherical feeder 710. The side of the first support ring 715 near the impeller chamber 702 is rigidly connected to the sealing plate 712. The support shaft 705 moves through the first through hole on the sealing plate 712 and is sealed between the two by an O-ring seal 711. The cam push shaft 724 passes through the first support ring 715 and the second support ring 720 in sequence. A spring 718 is sleeved on the cam push shaft 724. The two ends of the spring 718 are fixedly connected to the first baffle 716 and the second support ring 720 on the cam push shaft 724, respectively. A three-stage cam 709 cooperates with the cam push shaft 724 and is used to make the cam push shaft 724 located at three different heights.

[0065] Preferably, the cam push shaft 724 includes a cam roller 713, which is installed at the end of the rectangular stepped shaft 714 and contacts the third-stage cam 709; the other end of the rectangular stepped shaft 714 is rigidly connected to the first baffle 716; the side of the first baffle 716 away from the rectangular stepped shaft 714 is rigidly connected to the circular stepped shaft 719; a second baffle 721 and a third baffle 722 are sequentially installed on a section of the circular stepped shaft 719 extending outward from the second support ring 720; the first baffle 716, the second baffle 721, and the third baffle 722 protrude into and contact the side of the atomizing chamber 703 away from the impeller chamber 702; the side of the atomizing chamber 703 away from the impeller chamber 702 has a plurality of vent holes 723 and a plurality of first discharge holes 725; at least two first discharge holes 725 correspond to the first baffle 716, the second baffle 721, and the third baffle 722 respectively;

[0066] A hemispherical feeder 710 is installed on the side of the atomizing chamber 703 away from the impeller chamber 702. The outer surface of the hemispherical feeder 710 has several second discharge holes 708. Several discharge pipes are installed inside the hemispherical feeder 710. One end of each discharge pipe is connected to a first discharge hole 725, and the other end is connected to a second discharge hole 708. The discharge pipes are flexible hoses, arranged in a serpentine pattern within the hemispherical feeder 710. One end of each discharge pipe is sealed to the first discharge hole 725 via a quick-connect fitting, and the other end is sealed to the second discharge hole 708 via a quick-connect fitting.

[0067] The working principle and beneficial effects of the above technical solution are as follows:

[0068] 1. The atomizer 7 is designed with a pressure concentrating baffle 701, an impeller chamber 702, and an atomization chamber 703. Through the through-holes in the pressure concentrating baffle 701, the material receives higher pressure within the impeller chamber 702, driving the impeller 704 to rotate, which in turn causes the three-stage cam 709 to rotate faster. This design increases the pressure and speed during liquid spraying, accelerates the alternating discharge frequency of the first discharge hole 725, improves the atomization effect, and allows the material to be better atomized into fine particles.

[0069] 2. The support shaft 705 is connected to the three-stage cam 709 via a key. Driven by the three-stage cam, the spring 718 cyclically drives the cam push shaft 724 to three different heights, thereby causing the first baffle 716, the second baffle 721, and the third baffle 722 on the cam push shaft 724 to alternately open or close the first discharge hole 725, thus atomizing the material. This method can control the spray rate and angle of the liquid, further accelerating the atomization speed and optimizing the atomization effect.

[0070] 3. The side of the first support ring 715 closest to the impeller cavity 702 is rigidly connected to the sealing circular plate 712, and the side of the first support ring 715 furthest from the impeller cavity 702 is rigidly connected to the hemispherical conveyor 710. At the same time, sealing devices are provided at the through holes of both the first support ring 715 and the sealing circular plate 712. This design creates a sealed environment for the movement of the three-stage cam 709, which can effectively prevent materials from hindering the movement of the three-stage cam 709, thereby accelerating the atomization speed, reducing the wear of the three-stage cam 709, and increasing its service life.

[0071] 4. The first discharge hole 725 and the second discharge hole 708 are connected through a discharge pipe. At the same time, the second discharge hole 708 is evenly distributed on the surface of the hemispherical conveyor 710, which can effectively control the direction and range of material spraying and ensure that the atomized material is evenly distributed and discharged during the drying process.

[0072] 5. The hemispherical feeder 710 is installed outside the atomizing chamber 703. The first discharge hole 725 and the second discharge hole 708 are connected through the internal discharge pipe, which realizes the effective alternating discharge of atomized material in different directions, increases the utilization rate of material, further improves the atomization effect, and greatly increases the drying efficiency.

[0073] In summary, the atomizer in this embodiment has a complex and sophisticated design. By combining the pressure concentrating baffle, support shaft, cam push shaft, support plate, support ring, discharge hole, and feeder, it can achieve precise spray adjustment, improve the uniformity, consistency, and controllability of the spray, thereby improving the efficiency of the drying device and the product quality.

A horizontal piston 127 is slidably connected inside the upper outer shell 125. A vertical piston rod 128 is fixedly connected to the lower end of the horizontal piston 127. The vertical piston rod 128 slides through the upper end of the lower outer shell 126. An auxiliary spring is fixedly connected between the horizontal piston 127 and the inner wall of the lower end of the upper outer shell 125. An auxiliary cavity 129 is located inside the upper outer shell 125 above the horizontal piston 127. The air inlet of the auxiliary cavity 129 is connected to a pressurized gas supply device 1210 through a first pipe.

[0079] Two sets of symmetrical auxiliary components, the auxiliary components including:

[0080] The exhaust pipe 1211 penetrates the left or right side wall of the upper housing 125. The initial position of the exhaust pipe 1211 is below the horizontal piston 127, and an exhaust port is provided below the exhaust pipe 1211.

[0081] The connecting block 1212 is fixedly connected to the left or right side of the vertical piston rod 128. The connecting block 1212 is located inside the lower housing 126. An auxiliary inclined surface 1213 is provided on the side of the connecting block 1212 away from the vertical piston rod 128. The auxiliary inclined surface 1213 on the right side is lower on the left and higher on the right.

[0082] The first end of the horizontal mounting rod 1214 is set as an auxiliary arc surface, which contacts the auxiliary inclined surface 1213. The second end of the horizontal mounting rod 1214 is located outside the lower housing 126.

[0083] The limiting plate 1215 is fixedly connected to the second end of the horizontal mounting rod 1214, and an auxiliary spring is fixedly connected between the limiting plate 1215 and the lower outer shell 126.

[0085] The mating rod 1217 is integrally fixed on the upper end of the horizontal mounting rod 1214, and the mating rod 1217 contacts the side of the V-shaped pipe 1216 near the lower outer casing 126.

[0086] The second auxiliary mechanism has the aforementioned main component and the auxiliary component on the left side, and the third auxiliary mechanism has the aforementioned main component and the auxiliary component on the right side.

[0087] The working principle and beneficial effects of the above technical solution are as follows:

[0088] 1. A dust removal filter bag is fitted on the filter bag frame 124. The horizontal partition plate 122 is provided with an air outlet channel for each filter bag frame 124 to connect with the dust removal filter bag. Under the action of the vacuum pump 13, the gas containing carbon black in the drying furnace body 801 enters the dust removal filter bag for filtration, and the filtered air is discharged through the air outlet channel.

[0089] 2. In the initial state, such as Figure 8 As shown, when it is necessary to clamp and limit the dust collector filter bag, the pressure gas supply device 1210 can be controlled to input a small amount of compressed air into the auxiliary chamber 129. Under the pressure of the compressed gas, the horizontal piston 127 moves downward (the horizontal piston 127 is still located above the exhaust pipe 1211). The horizontal piston 127 drives the vertical piston rod 128 and the connecting block 1212 to move downward, so that the auxiliary arc surface and the auxiliary inclined surface 1213 cooperate, so that the two horizontal mounting rods 1214 on the left and right move away from each other, so that the limiting plate 1215 is pressed on the corresponding side of the corresponding dust collector filter bag, ensuring the connection stability of the dust collector filter bag.

[0090] 3. (1) When there is a lot of carbon black adsorbed on the outside of the dust collector filter bag, the pressure gas supply device 1210 can be controlled to continuously input a large amount of compressed air into the auxiliary chamber 129 for a certain period of time. Under the pressure of the compressed gas, the horizontal piston 127 moves downward to the auxiliary chamber 129 and connects with the exhaust pipe 1211. The compressed gas enters the V-shaped pipe 1216 through the exhaust pipe 1211 and then is discharged to blow air onto the corresponding side of the corresponding dust collector filter bag, so that the carbon black falls from the dust collector filter bag.

[0091] (2) The horizontal piston 127 drives the vertical piston rod 128 and the connecting block 1212 to move downward, so that the auxiliary arc surface and the auxiliary inclined surface 1213 cooperate, so that the two horizontal mounting rods 1214 move away from each other, so that the limiting plate 1215 impacts the corresponding side of the corresponding dust filter bag, accelerating the carbon black from falling from the dust filter bag.

[0092] (3) The mating rod 1217 on the horizontal mounting rod 1214 pushes the corresponding V-shaped pipe 1216 to rotate, adjusting the blowing range of the V-shaped pipe 1216 to ensure the blowing effect; and the pressure gas supply device 1210 can periodically input a large amount of compressed air into the auxiliary chamber 129 to realize the periodic operation of the limit plate 1215 and the periodic swing of the V-shaped pipe 1216, periodically realizing the above-mentioned functions (1)-(3);

[0093] (4) Furthermore, the present invention can achieve the above-mentioned multifunctionality of multiple dust filter bags by controlling the operation of the pressure gas supply device 1210, which is convenient to control.

[0094] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
