Description

Technical Field

[0001] This utility model relates to the field of carbon black production technology, specifically to a granular carbon black cooling device. Background Technology

[0002] Carbon black is a fine powder or granular substance produced by the incomplete combustion or pyrolysis of carbon-containing raw materials at high temperatures. It is widely used in many fields such as rubber, plastics, inks, coatings, batteries, and conductive materials. Carbon black is usually generated at high temperatures during the production process, especially after granulation into granular carbon black, where the temperature is still high. If it is not cooled in time, it will not only affect subsequent packaging and storage processes, but also easily cause problems such as equipment adhesion, particle agglomeration, and deterioration of physical properties. In severe cases, it may even cause safety hazards.

[0003] In existing technologies, the cooling of granular carbon black is mostly achieved by methods such as forced air, natural stacking, or water cooling devices. However, these cooling methods have certain limitations: natural cooling has low efficiency and requires a large space; forced air cooling depends on the ambient air temperature and the temperature control is unstable; while traditional water cooling structures are mostly single-pass heat exchangers with low heat exchange efficiency, and uneven heat distribution during the cooling process can easily lead to incomplete cooling of granular carbon black, affecting product quality.

[0004] In addition, some existing cooling devices lack a linkage mechanism for dynamic conveying and temperature equalization control of carbon black particles in their structural design, which leads to local heat accumulation, cooling lag, or overcooling of carbon black in the cooling chamber, which is not conducive to the needs of continuous and automated production. Utility Model Content

[0005] The purpose of this invention is to provide a particulate carbon black cooling device to solve the problems of low efficiency, unstable temperature control, and difficulty in meeting the needs of continuous production in the existing cooling methods mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a granular carbon black cooling device, comprising a carbon black cooling device body, a heat dissipation mechanism on the top of the carbon black cooling device body, the heat dissipation mechanism comprising a cooling fan, a heat dissipation pipe, a heat conduction pipe, a cooling box, a heat transfer pipe, a heat conduction plate, a transfer pump, and a transfer pipe, a mounting plate fixedly connected to the bottom end of the cooling fan, the mounting plate fixedly connected to the outer wall of the carbon black cooling device body, a heat transfer pipe fixedly connected to the outer wall of the cooling fan, a heat dissipation pipe fixedly connected to one end of the heat transfer pipe, and a heat dissipation auxiliary mechanism on one side of the top of the carbon black cooling device body, the heat dissipation auxiliary mechanism comprising a movable support, a temperature control switch, a motor, and a lead screw, a temperature control switch fixedly connected to the bottom end of the movable support, a threaded connection between the middle part of the lead screw and the movable support, and an electrical connection between the temperature control switch and the cooling fan.

It has significant application value in improving product quality and saving energy and reducing consumption. Attached Figure Description

[0022] 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

[0023] like Figures 1 to 4 As shown, a particulate carbon black cooling device according to the first aspect of this utility model includes a carbon black cooling device body 1. A heat dissipation mechanism 3 is provided on the top of the carbon black cooling device body 1. The heat dissipation mechanism 3 includes a cooling fan 301, a heat dissipation pipe 302, a heat conduction pipe 303, a cooling box 304, a heat transfer pipe 305, a heat conduction plate 307, a transfer pump 312, and a transfer pipe 313. A mounting plate 309 is fixedly connected to the bottom end of the cooling fan 301, and the mounting plate 309 is fixedly connected to the outer wall of the carbon black cooling device body 1. A heat transfer pipe 305 is fixedly connected to the outer wall of the cooling fan 301. A heat dissipation pipe 302 is fixedly connected to one end of the heat transfer pipe 305. A heat dissipation auxiliary mechanism 5 is provided on one side of the top of the carbon black cooling device body 1. The heat dissipation auxiliary mechanism 5 includes a movable support 506, a temperature control switch 503, a motor 505, and a lead screw 504. The temperature control switch 503 is fixedly connected to the bottom end of the movable support 506. The middle part of the lead screw 504 is threadedly connected to the movable support 506. The temperature control switch 503 is electrically connected to the cooling fan 301.

[0024] One end of the heat dissipation pipe 302 is fixedly connected to one end of the connecting pipe 310, one end of the connecting pipe 310 is fixedly connected to the inlet end of the transfer pump 312, the outlet end of the transfer pump 312 is fixedly connected to the transfer pipe 313, and the other end of the heat dissipation pipe 302 is fixedly connected to the heat conduction pipe 303.

[0025] It should be noted that the heat-conducting plate 307, as a heat transfer component, is installed at the top of the carbon black cooling device body 1 to receive the heat transfer energy inside the device. In particular, when the granular carbon black is transported to the top via the spiral conveyor blade 6 at high temperature, the heat is first transferred to the heat-conducting plate 307. The bottom end of the heat-conducting pipe 303 is in close contact with the top surface of the heat-conducting plate 307, which can quickly guide the heat absorbed by the heat-conducting plate 307 into the cooling circuit. In order to form a closed loop, a return pipe 311 is fixedly connected to one end of the heat-conducting plate 307. The return pipe 311 is used to guide the coolant after heat exchange back to the cooling box 304, thereby forming a closed-loop heat exchange path, realizing the circulation of the heat-conducting liquid and efficient heat recovery, and improving the overall heat dissipation efficiency.

[0026] A heat-conducting plate 307 is fixedly connected to the top of the carbon black cooling device body 1, the bottom end of the heat-conducting pipe 303 is attached to the top of the heat-conducting plate 307, and a return pipe 311 is fixedly connected to one end of the heat-conducting plate 307.

[0027] It should be noted that the coolant circulation system uses the cooling tank 304 as the core of the circulation storage. The transfer pump 312 draws coolant from the top of the cooling tank 304 and sends it to the heat dissipation pipe 302 and heat conduction pipe 303 through the transfer pipe 313 to complete the heat absorption of the heat conduction plate 307. After heat absorption, the heated liquid returns to the cooling tank 304 along the return pipe 311. The temperature drops through the heat exchange mechanism on the outer wall of the tank or natural convection, and the liquid enters the next cycle. This structural design ensures the continuity and stability of the coolant flow in the closed loop, and effectively avoids local fluid stagnation through the upper and lower distributed inlet and outlet channels, thereby improving cooling efficiency and extending the service life of the coolant.

[0028] One end of the return pipe 311 is fixedly connected to the outer wall of the cooling box 304, the bottom end of the transmission pipe 313 is fixedly connected to the top end of the cooling box 304, and the bottom end of the transmission pump 312 is fixedly connected to the top of the cooling box 304.

[0029] A cover plate 306 is snapped onto the top of the heat-conducting plate 307, and heat dissipation fins 308 are fixedly connected to the outer wall of the heat-conducting plate 307.

[0030] A motor 2 is fixedly connected to one side wall of the carbon black cooling device body 1. A spiral conveyor blade 6 is fixedly connected to the output end of the motor 2. The rotation of the spiral conveyor blade 6 is connected to the inner wall of the carbon black cooling device body 1. A feed inlet 4 is opened at the top of the carbon black cooling device body 1, and a discharge outlet 7 is opened at the bottom of the carbon black cooling device body 1.

[0031] It should be noted that the spiral conveyor blades 6 driven by motor 2 are used to transport the granular carbon black in an orderly manner. The spiral conveyor blades 6 are arranged around the inner wall of the carbon black cooling device body 1. During the rotation, they can continuously turn and push the granular carbon black, so as to avoid its accumulation during the transport. At the same time, they enhance the heat exchange efficiency with the heat-conducting plate 307 and the inner wall. The carbon black enters from the feed port 4 at the top of the device, is conveyed by the spiral to the area of ​​the heat-conducting plate 307 for cooling, and is finally discharged from the discharge port 7 at the bottom. This structural design ensures that the carbon black is in a dynamic flow state throughout the cooling process, which helps to achieve continuous cooling and improve the cooling uniformity, and avoids local overheating or hot spot effects caused by carbon black accumulation.

[0032] The technical effect achieved by the above embodiment is as follows: By setting a heat dissipation mechanism 3 and auxiliary structures on the top of the carbon black cooling device body 1, the aim is to achieve efficient and uniform cooling of granular carbon black. When the high-temperature granular carbon black enters the carbon black cooling device body 1 through the top feed port 4, the spiral conveyor blade 6 is driven to rotate by the motor 2 set on one side of the body, thereby driving the carbon black particles to be continuously conveyed inside the body. During the conveying process, the particles form thermal contact with the inner wall and the heat-conducting plate 307, and transfer some heat to the heat-conducting plate 307 through heat conduction. The top of the heat-conducting plate 307 is provided with heat dissipation fins 308 to expand the heat dissipation surface area and enhance the heat dissipation efficiency. At the same time, the heat-conducting pipe 303 is closely attached to the top of the heat-conducting plate 307 and is in contact with the heat dissipation fins 308. Heat pipe 302 is connected, and gas or liquid circulation cooling is achieved through heat transfer pipe 305 and cooling fan 301. In the heat dissipation circulation path formed by heat transfer pipe 305 and cooling fan 301, the cooling medium is drawn from the cooling box 304 under the drive of transfer pump 312, enters the heat dissipation pipe 302 through connecting pipe 310, absorbs heat from heat conduction plate 307 through heat conduction pipe 303, and finally the hot liquid returns to the cooling box 304 through return pipe 311 to complete the circulation, thereby achieving the cooling effect. This cooling circulation path is designed as a closed system to ensure cooling efficiency and safety, and the cooling fan 301 enhances air convection to further promote heat release, effectively preventing carbon black from agglomerating, smoking or static electricity accumulation due to excessive temperature. Example

[0033] like Figure 3 and Figure 4 As shown, a particulate carbon black cooling device includes all the contents of Example 1. In addition, a motor 505 is fixedly connected to one side of the top of the carbon black cooling device body 1. The output end of the motor 505 is fixedly connected to one end of the lead screw 504. A fixing plate 501 is fixedly connected to the inner side of the cover plate 306. The inner side of the fixing plate 501 is rotatably connected to the other end of the lead screw 504. A sliding groove 502 is provided at the top of the cover plate 306. A movable support 506 is slidably connected to the inner wall of the sliding groove 502.

[0034] The technical effect achieved by the above embodiment is as follows: In order to achieve precise control of the cooling process of granular carbon black, this device is equipped with a heat dissipation auxiliary mechanism 5, which is used to dynamically adjust the working state of the cooling fan 301 according to the temperature change and distribution at the top of the carbon black cooling device body 1. The auxiliary mechanism includes components such as a movable support 506, a lead screw 504, a motor 505, and a temperature control switch 503. The temperature control switch 503 is installed at the bottom of the movable support 506 and located in the top area of ​​the carbon black cooling device body 1. It is used to detect in real time whether the temperature distribution in this area is uniform. When the temperature control switch 503 detects a large temperature difference in the top area, that is, uneven temperature distribution, it will output an electrical signal to drive the motor 505 to rotate, thereby driving the lead screw 504 connected to it to rotate, so that the movable support 506 fixed at both ends of the lead screw 504 rotates. 06 moves horizontally along the slide 502, thereby adjusting the structural fit between the cover plate 306 and the heat-conducting plate 307. At the same time, the temperature control switch 503 is also electrically connected to the control module of the cooling fan 301. It can adjust the speed and power output of the cooling fan 301 according to the detection results. If the overall temperature at the top is too high or the local temperature difference is too large, the cooling fan 301 will increase the speed and air volume to enhance air circulation and heat transfer fluid circulation. Conversely, when the temperature tends to be uniform or too low, the fan will automatically reduce its speed or even stop working to reduce energy consumption and prevent condensation. The above design makes the heat dissipation efficiency no longer a constant output, but intelligently adjusted according to the real-time thermal field state, ensuring that the particulate carbon black has a uniform temperature and stable cooling when passing through the top of the body, preventing agglomeration or uneven heat distribution caused by local overheating, and significantly improving the cooling quality and system energy efficiency.

[0035] 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.
