Description

Technical Field

[0001] This utility model relates to the field of carbon black processing technology, specifically a carbon black granulator. Background Technology

[0002] Carbon black is an important inorganic powder material widely used in various industrial fields such as rubber, plastics, inks, coatings, and batteries. It plays a key role, especially in tire manufacturing and conductive composite materials. Since carbon black is usually generated in the form of extremely fine powder during the production process, it has the characteristics of small particle size, large specific surface area, easy dispersion, and easy agglomeration. If it is directly packaged, transported, or used, it can easily cause problems such as dust pollution, material loss, and equipment adhesion, which are not conducive to process stability and environmental safety. Therefore, in order to improve the workability and storage and transportation performance of carbon black, its powdered raw materials need to be processed into granular products through a certain process, that is, carbon black granulation treatment.

[0003] A carbon black granulator is a device specifically designed to convert carbon black powder into granules. It mainly uses steps such as stirring, pressing, agglomeration, and drying to form carbon black powder into granular products with suitable particle size and uniform density. In actual use, traditional carbon black granulators often suffer from problems such as poor material feeding, material sticking to the wall and clogging, uneven stirring, and severe agglomeration. Especially in continuous production, these defects can seriously affect production line efficiency and product quality. Therefore, how to improve the stability of carbon black feeding, enhance the uniformity of granulation, and reduce the frequency of manual intervention and maintenance has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0004] The purpose of this invention is to provide a carbon black granulator to solve the problems of poor carbon black feeding, easy clogging, and uneven mixing mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a carbon black granulator, comprising a carbon black granulator body, wherein a feeding auxiliary mechanism is provided on the top of the carbon black granulator body, the feeding auxiliary mechanism comprising a transmission blade, a transmission rod, a transmission block and a feeding cylinder, the inner wall of the feeding cylinder being rotatably connected to both ends of the transmission blade, one side of the transmission blade being fixedly connected to one end of the transmission rod, the other end of the transmission rod passing through the feeding cylinder and being fixedly connected to the inner side of the transmission block, and a pre-stirring mechanism being provided inside the carbon black granulator body, the pre-stirring mechanism comprising a motor, a stirring shaft one and a stirring shaft two, the output end of the motor one being fixedly connected to the stirring shaft one, and the stirring shaft two being rotatably connected inside the carbon black granulator body.

[0006] Furthermore, a protective box is fixedly connected to the bottom end of the feeding cylinder, and a baffle is engaged with the inner wall of the feeding cylinder.

[0007] Furthermore, limit plates are fixedly connected to both sides of the top of the protective box.

[0008] Furthermore, two spring reset rods are fixedly connected to the top of the protective box, and the free ends of the two spring reset rods are fixedly connected to the bottom end of the collar.

[0009] Furthermore, a sleeve is fixedly connected to the outer wall of the feeding cylinder, and a striking rod is slidably connected to the inner wall of the sleeve. A return spring is sleeved in the middle of the striking rod. One end of the return spring is fixedly connected to the inner wall of the striking rod, and the other end of the return spring is fixedly connected to the inner wall of the sleeve. A collar one and a collar two are slidably connected between the two limiting plates, respectively.

[0010] Furthermore, one end of the striking rod passes through the sleeve, and a first magnetic attraction is fixedly connected to one end of the striking rod. A second magnetic attraction is fixedly connected to the inner side of both the first and second collars, and the first and second magnetic attractions are magnetically attracted to each other.

[0011] Furthermore, the upper and lower ends of the transmission block are respectively attached to the outer sides of the first collar and the second collar, the bottom end of the motor is fixedly connected to the top end of the carbon black granulator body, the top end of the carbon black granulator body is fixedly connected to the mixing chamber, and the first mixing shaft is rotatably connected to the inside of the mixing chamber.

[0012] Furthermore, a hopper is fixedly connected to the top of the mixing chamber, and the top of the hopper is fixedly connected to the bottom of the protective box. A discharge port is provided at the bottom of the carbon black granulator body.

[0013] Compared with existing technologies, the beneficial effects of this utility model are as follows: This carbon black granulator has significant advantages in structural optimization and functional synergy, which can effectively improve the feeding stability and particle uniformity during the carbon black raw material granulation process. By setting a feeding auxiliary mechanism, the material's own weight drives the transmission blade to drive the transmission block to rotate eccentrically, thereby realizing a striking action that combines magnetic attraction drive and spring reset. This effectively solves the problem of wall sticking and blockage that easily occurs in traditional equipment during powder feeding, improving the smoothness and continuity of material conveying. At the same time, the striking mechanism adopts a non-contact magnetic attraction drive structure, avoiding wear and failure caused by direct mechanical transmission, extending service life and reducing maintenance costs. The addition of the pre-stirring mechanism fully mixes and disperses the material before it enters the granulation zone, significantly improving the uniformity of the raw material and the consistency of granulation, preventing agglomeration and resulting in a decrease in particle quality. The overall machine structure is compact and reasonable, and the modules achieve linkage and collaborative control. It has the characteristics of high automation, strong stability, and wide adaptability, and is especially suitable for industrial carbon black granulation scenarios with large-scale and long-term operation, significantly improving granulation efficiency and finished product quality.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Example

[0018] like Figures 1 to 4As shown, a carbon black granulator according to the first aspect of this utility model includes a carbon black granulator body 1. The top of the carbon black granulator body 1 is provided with a feeding auxiliary mechanism 3. The feeding auxiliary mechanism 3 includes a transmission blade 307, a transmission rod 309, a transmission block 305, and a feeding cylinder 310. The inner wall of the feeding cylinder 310 is rotatably connected to both ends of the transmission blade 307. One side of the transmission blade 307 is fixedly connected to one end of the transmission rod 309. The other end of the transmission rod 309 passes through the feeding cylinder 310 and is fixedly connected to the inner side of the transmission block 305. The carbon black granulator body 1 is provided with a pre-stirring mechanism 2. The pre-stirring mechanism 2 includes a motor 203, a first stirring shaft 205, and a second stirring shaft 202. The output end of the first motor 203 is fixedly connected to the first stirring shaft 205, and the second stirring shaft 202 is rotatably connected to the inside of the carbon black granulator body 1.

[0019] A protective box 301 is fixedly connected to the bottom of the feeding cylinder 310, and a baffle 306 is snapped onto the inner wall of the feeding cylinder 310.

[0020] Limiting plates 302 are fixedly connected to both sides of the top of the protective box 301.

[0021] Two spring return rods 303 are fixedly connected to the top of the protective box 301, and the free ends of the two spring return rods 303 are fixedly connected to the bottom end of the collar 304.

[0022] It should be noted that the purpose of setting the spring return rod 303 is to provide the collar 304 with elastic reset capability in the vertical direction. When the elliptical structure of the transmission block 305 drives the collar 304 to rise and fall during rotation, the spring return rod 303 is compressed and deformed. When the transmission block 305 rotates to the low position and the collar 304 is disengaged from the drive, the spring return rod 303 can quickly return to its original shape by means of elastic deformation, thereby driving the collar 304 to return to its position quickly, ensuring the stability and timeliness of its cyclic reciprocating action. This structure can improve the response frequency and mechanical stability of the striking trigger mechanism and avoid affecting the smooth flow of material feeding due to mechanism jamming or slow response.

[0023] A sleeve 312 is fixedly connected to the outer wall of the feeding cylinder 310. A striking rod 311 is slidably connected to the inner wall of the sleeve 312. A return spring 313 is sleeved in the middle of the striking rod 311. One end of the return spring 313 is fixedly connected to the inner wall of the striking rod 311, and the other end of the return spring 313 is fixedly connected to the inner wall of the sleeve 312. A collar 1 304 and a collar 2 308 are slidably connected between the two limiting plates 302 respectively.

[0024] It should be noted that the sleeve 312 and the striking rod 311 form a vertical sliding fit mechanism, which can limit the axial movement direction of the striking rod 311 and prevent it from wobbling radially and affecting the working accuracy. The reset spring 313 is used to provide the energy storage and rebound function of the striking rod 311. After the striking rod 311 is stretched by external magnetic force, the reset spring 313 is compressed. When the magnetic attraction is released, the spring quickly releases the tension, driving the striking rod 311 to rebound at high speed, thereby impacting the outer wall of the feeding cylinder 310 and realizing the periodic vibration function. This type of structural design has good mechanical stability and self-resetting ability, which can effectively prevent material blockage or adhesion during the feeding process and improve the reliability and continuity of equipment operation.

[0025] One end of the striking rod 311 passes through the sleeve 312. A first magnet 314 is fixedly connected to one end of the striking rod 311. A second magnet 315 is fixedly connected to the inner side of the first collar 304 and the inner side of the second collar 308. The first magnet 314 and the second magnet 315 are magnetically attracted to each other.

[0026] It should be noted that the magnetic attraction structure is mainly used to temporarily drive and release the striking rod 311 without the need for rigid contact and connection. The second magnetic attraction 315 moves up and down with the first collar 304 or the second collar 308 under the action of the transmission block 305. During the movement, it gradually approaches and attracts the first magnetic attraction 314 at the end of the striking rod 311, thereby driving the striking rod 311 to slide outward and compress the return spring 313 in the middle. When the second magnetic attraction 315 descends and is misaligned with the first magnetic attraction 314, the attraction force is released, the return spring 313 immediately rebounds, and the striking rod 311 will strike the downward material cylinder 310.

[0027] The technical effect achieved by the above embodiment is as follows: During the operation of the carbon black granulator body 1, the carbon black raw material enters the feeding cylinder 310 through the protective box 301. As the material gradually accumulates, its gravity acts on the transmission blade 307 inside the feeding cylinder 310. Since both ends of the transmission blade 307 are rotatably connected to the inner wall of the feeding cylinder 310, it will rotate around its axis after being subjected to force, thereby driving the transmission rod 309 fixedly connected to one side to rotate. The other end of the transmission rod 309 is fixedly connected to the inner side of the transmission block 305. Therefore, the rotation of the transmission blade 307 will further drive the transmission block 305 to rotate eccentrically. The transmission block 305 is elliptical in shape, and its longer upper and lower ends will push the outer collar 1 304 and collar 2 308 in turn during the rotation, causing it to move up and down reciprocally. The inner side is fixed with second magnets 315. During the movement, these second magnets 315 will magnetically engage with the first magnets 314 at the end of the striking rod 311, thereby pulling the striking rod 311 to slide along the inner wall of the sleeve 312. The striking rod 311 is provided with a return spring 313 in the middle. When magnetically attracted, the striking rod 311 is pulled outward, thereby compressing the spring. When the transmission block 305 continues to rotate, the first collar 304 and the second collar 308 move down to be misaligned with the first magnet 314, the magnetic attraction is released, and the return spring 313 is quickly released, driving the striking rod 311 to quickly return and rebound, thereby impacting the wall of the feeding cylinder 310. This impact action can effectively shake off the carbon black powder attached to the inner wall of the feeding cylinder 310, prevent material accumulation and blockage, ensure continuous and smooth feeding of carbon black, and improve granulation stability. Example

[0028] like Figure 1 and Figure 2 As shown, a carbon black granulator includes all the contents of Example 1. In addition, the upper and lower ends of the transmission block 305 are respectively attached to the outer side of the first collar 304 and the outer side of the second collar 308. The bottom end of the motor 203 is fixedly connected to the top end of the carbon black granulator body 1. The top end of the carbon black granulator body 1 is fixedly connected to the mixing chamber 204. The first mixing shaft 205 is rotatably connected to the inside of the mixing chamber 204. The top end of the mixing chamber 204 is fixedly connected to the hopper 201. The top end of the hopper 201 is fixedly connected to the bottom end of the protective box 301. The bottom of the carbon black granulator body 1 is provided with a discharge port 4.

[0029] The technical effects achieved by the above embodiments are as follows: After the material enters through the feeding cylinder 310, the knocking function formed by gravity and the transmission mechanism ensures its stable fall. It then enters the mixing chamber 204 inside the carbon black granulator body 1. A hopper 201 is located at the top of the mixing chamber 204, and the hopper 201 is fixedly connected to the bottom of the protective box 301, forming a closed material guide channel. This prevents dust from overflowing and improves the environmental friendliness of the operation. The output end of the motor 203 is fixedly connected to the first mixing shaft 205. The first mixing shaft 205 is rotatably installed inside the mixing chamber 204 and works in coordination with the mixing chamber 204 at the top of the carbon black granulator body 1. Simultaneously, the second mixing shaft... 202 is also located inside the granulator body and is rotatably connected. The two work together to form a three-dimensional stirring structure. This pre-stirring mechanism 2 initially disperses and evenly mixes the carbon black before it enters the granulation zone, effectively preventing the raw materials from clumping and having uneven density, and improving the subsequent granulation quality. Finally, the processed material is discharged through the discharge port 4 set at the bottom of the carbon black granulator body 1, forming a continuous and stable carbon black particle output process. The whole machine integrates automatic anti-blocking, magnetic attraction driving knocking, spring reset striking and motor 203 power stirring through upper and lower coordinated linkage. It has the advantages of compact structure, high efficiency and high degree of automation, and is suitable for industrial-scale carbon black granulation production.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
