Description

Technical Field

[0001] The invention relates to the technical field of carbon black pulverization, and in particular to an automatic temperature-controlled pulverizer for carbon black production. Background Art

[0002] With the development of industrial technology, carbon black, as an important industrial raw material, has been widely used in many fields such as rubber, plastics, coatings, inks, etc. The production process of carbon black mainly includes reaction, cooling, crushing and collection steps; among them, crushing is one of the key links to ensure the quality of carbon black products. It is not only related to the fineness of carbon black, but also directly affects the performance of the product and the convenience of subsequent processing.

[0003] At present, most of the carbon black production pulverizers on the market are traditional mechanical pulverizing equipment. Although these equipment can meet basic pulverizing needs, some problems are exposed in actual applications: First, most traditional pulverizers lack an effective temperature control mechanism. During the carbon black pulverization process, a large amount of heat will be generated due to the friction between the high-speed rotating pulverizers and the material and the collision of the material itself. If the heat cannot be controlled in time and effectively, the temperature of the carbon black may rise, which in turn causes changes in the properties of the carbon black, such as increased viscosity and poor fluidity. What is more serious is that high temperature may also induce carbon black spontaneous combustion or explosion, posing a great hidden danger to production safety; secondly, traditional carbon black production pulverizers also have obvious deficiencies in the material collection link. Most equipment adopts the method of directly connecting the cloth bag to the discharge port for collection. Although this method is simple, it is inefficient. When the carbon black in the cloth bag accumulates to a certain amount, the production line needs to be stopped to replace the new cloth bag, which not only increases the workload of the operator, but also the frequent shutdown and start-up will affect the production efficiency and the service life of the equipment. Summary of the invention

[0036] See also Figure 4-Figure 6 As shown, the rotating mechanism includes a servo motor 701, a rotating shaft 702, a cone 703 and a connecting frame 704; a servo motor 701 is arranged in the middle of the bottom of the closed cylinder 2, and the servo motor 701 is electrically connected to the controller 301; the rotating shaft 702 is connected to the output shaft of the servo motor 701; five cones 703 are arranged at intervals on the rotating shaft 702, and the bottoms of the five cones 703 are rotatably connected to the tops of five trays 6 respectively; connecting frames 704 are arranged at annular intervals on the cones 703, and the connecting frame 704 is rotatably connected to the crushing wheel 8.

[0037] See also Figure 7 As shown, the guiding mechanism includes a connecting tube 1101 and a first air pump 1102; the top of the closed tube 2 is connected to the through hole on the upper right side of the storage frame 10 through the connecting tube 1101; the first air pump 1102 is installed on the upper left side of the storage frame 10, and the air inlet of the first air pump 1102 is connected to the through hole on the upper left side of the storage frame 10. The first air pump 1102 is used to draw the carbon powder in the closed tube 2 into the storage frame 10 through the connecting tube 1101, and the first air pump 1102 is electrically connected to the controller 301.

[0038] See also Figure 7 and Figure 8 As shown, the discharge mechanism includes a discharge pipe 1601 and a baffle 1602 ; the bottom of the storage frame 10 is connected to the discharge pipe 1601 ; a baffle 1602 is slidably provided on the discharge pipe 1601 , and the baffle 1602 is used to block the inner side of the discharge pipe 1601 .

[0039] When in use, firstly, the controller 301 controls the temperature detector 201 to detect the temperature inside the closed cylinder 2, and then controls the servo motor 701 to drive the rotating shaft 702 to rotate, thereby driving the cone 703, the connecting frame 704 and the crushing wheel 8 to rotate, and then controls the cold and hot air blower 9 to blow cold air or hot air into the closed cylinder 2 through the bar holes 401 of the annular frame 4 from bottom to top, so that the cold air flows into the storage frame 10 through the connecting pipe 1101, and the temperature inside the closed cylinder 2 is detected by the temperature detector 201. If the temperature detected by the temperature detector 201 becomes higher and higher, the controller 301 will also control the cold and hot air blower 9 to blow out cold air with lower and lower temperature. If the temperature detected by the temperature detector 201 becomes lower and lower, the controller 301 will also control the cold and hot air blower 9 to blow out hot air with higher and higher temperature, so as to achieve the desired effect. The temperature is controlled in the closed cylinder 2 to ensure that the carbon black in the closed cylinder 2 is within a suitable temperature range (if the temperature of the carbon black is too high, the interaction force between the carbon black particles will be enhanced, making the carbon black more viscous and having poor fluidity. In addition, carbon black is a flammable substance and is prone to spontaneous combustion or explosion under high temperature conditions, especially in the presence of oxygen, the risk is higher; if the temperature of the carbon black is too low, the hygroscopicity of the carbon black may be enhanced, absorbing moisture in the air, resulting in agglomeration and performance degradation). Then, the controller 301 controls the first air pump 1102 to extract the air in the connecting pipe 1101 and the closed cylinder 2, so that the air in the connecting pipe 1101 and the closed cylinder 2 is discharged faster. Then, the controller 301 controls the reduction motor 12 to drive the perforated rotating frame 13, the partition frame 14 and the filter cloth 15 to rotate, so that the eight spaces separated on the rotating frame 13 are aligned one by one with the through holes of the storage frame 10. Then, a proper amount of carbon black is continuously fed into the closed cylinder 2 through the screw feeder 302. When the carbon black enters the closed cylinder 2, it is affected by the cold air or hot air in the closed cylinder 2. The cold air or hot air will cool down or heat up the carbon black in the closed cylinder 2 to ensure that the temperature of the carbon black is within a suitable range to prevent the carbon black from changing its properties due to excessively high or low temperature. At the same time, the carbon black will fall down on the topmost cone 703 due to gravity, and then the carbon black will slide on the cone 703 to the annular groove 601 of the topmost tray 6. After a proper amount of carbon black is loaded into the annular groove 601, the excess carbon black will fall down from the gap between the inner side of the funnel 5 and the tray 6. After the excess carbon black contacts the funnel 5, the excess carbon black will fall through the funnel 5 to the next layer of cones 703, and then the above actions will be repeated to disperse the carbon black in the annular grooves 601 of the five trays 6, thereby preventing excessive carbon black from accumulating in the annular groove 601 of the uppermost tray 6. When the carbon black in the annular groove 601 contacts the rotating crushing wheel 8, the crushing wheel 8 will crush the carbon black in the annular groove 601 to crush the carbon black. When the carbon black is gradually crushed into carbon powder, the carbon powder will remain in the annular groove 601. Since the cold air or hot air in the closed cylinder 2 is blown from bottom to top, when the cold air or hot air flows out from the strip holes 401 of the annular frame 4, the cold air or hot air will be discharged from the strip holes 401 of the annular frame 4. The cold or hot wind will drive the carbon powder in the annular groove 601 to float upward, so that the carbon powder in the closed cylinder 2 enters the connecting pipe 1101 and the storage frame 10 together with the cold wind or hot wind. During this period, the air in the connecting pipe 1101 and the closed cylinder 2 is extracted by the first air pump 1102, which can accelerate the carbon powder in the connecting pipe 1101 and the closed cylinder 2 to float into the storage frame 10. After the carbon powder enters the storage frame 10, the carbon powder will enter the space aligned with the through hole in the eight spaces on the rotating frame 13, and then the filter cloth 15 in the space will filter out the carbon powder in the air, so that the carbon powder stays on the filter cloth 15 in the space. When the space rotates to the bottom, the filter cloth in the space The carbon powder on 15 will fall down to the lower side of the storage frame 10 due to gravity and be collected. In this way, the carbon black can be automatically crushed and the temperature of the carbon black in the closed cylinder 2 can be automatically controlled so that the carbon black is at a suitable temperature. Later, when the carbon powder in the storage frame 10 needs to be discharged, the baffle 1602 is pulled to the left to make the carbon powder in the storage frame 10 fall down through the discharge pipe 1601 to be discharged. In this way, the operator can discharge the carbon powder conveniently without stopping the machine for the discharge operation, which not only saves time and effort but also improves production efficiency. After the carbon powder in the storage frame 10 has been discharged, the baffle 1602 is pushed to the right to reset.

[0040] See also Figure 10-12As shown, it also includes a blower mechanism, which includes a second air pump 17, a hollow frame 18 and an annular air outlet pipe 20; the second air pump 17 is installed at the bottom of the lowermost tray 6, and the second air pump 17 is electrically connected to the controller 301; a hollow frame 18 is rotatably installed on the lower side of the rotating shaft 702, and the hollow frame 18 is connected to the air outlet of the second air pump 17; an air flow channel 19 is opened on the inner side of the rotating shaft 702, and the hollow frame 18 is connected to the air flow channel 19; an annular air outlet pipe 20 is connected to the cone 703, the air outlet of the annular air outlet pipe 20 is aligned with the annular groove 601 of the tray 6, and the annular air outlet pipe 20 is connected to the air flow channel 19 in the rotating shaft 702, and the annular air outlet pipe 20 is used to blow out the carbon powder adhered to the annular groove 601 to prevent the carbon powder from adhering to the annular groove and affecting the subsequent crushing effect.

[0041] When in use, the controller 301 can be used to control the second air pump 17 to draw air into the hollow frame 18, so that the air flows through the airflow channel 19 in the rotating shaft 702 to the annular air outlet pipe 20, so that the annular air outlet pipe 20 blows the air into the annular groove 601, thereby blowing out the carbon powder adhered to the annular groove 601 to prevent the carbon powder from adhering to the annular groove 601 and causing residue.

[0042] See also Figure 13-Figure 15 As shown, a cooling mechanism is also included, which includes a water circulation cooling box 21, a water outlet pipe 22 and a return pipe 23; a water circulation cooling box 21 is installed on the lower right side of the support frame 1, and the water circulation cooling box 21 is electrically connected to the controller 301; the water circulation cooling box 21 is connected to five trays 6 through a water outlet pipe 22; the water circulation cooling box 21 is connected to five trays 6 through five return pipes 23; an arc channel 24 is opened on the inner side of the tray 6, and the arc channel 24 is located directly below the annular groove 601, and the water outlet pipe 22 and the return pipe 23 are both connected to the arc channel 24.

[0043] See also Fig.14 As shown, a regulating valve 25 is also included; the regulating valve 25 is arranged on the return pipe 23, and the regulating valve 25 is used to adjust the flow rate of the clean water in the return pipe 23.

[0044] When in use, the controller 301 can be used to control the water circulation cooling box 21 to introduce clean water into the water outlet pipe 22, so that the clean water flows into the arc channel 24 in the tray 6 through the water outlet pipe 22. When the clean water enters the arc channel 24, the heat of the tray 6 will be taken away by the water flow, and the tray 6 will be cooled down (the reason for cooling the tray 6: when the carbon black is crushed in the annular groove 601, the carbon black will rub against the tray 6, thereby causing the temperature of the tray 6 to rise), thereby preventing the heat of the tray 6 from being transferred to the carbon black, and avoiding the carbon black temperature from being too high. After that, the clean water in the arc channel 24 will flow back to the water circulation cooling box 21 through the return pipe 23 for recycling, thereby continuously cooling the tray 6; during this period, the clean water flow rate in the return pipe 23 can be adjusted by the regulating valve 25, so that the clean water flow rate in the return pipe 23 is less than the water flow rate in the outlet pipe 22, thereby ensuring that the outlet pipe 22 can deliver clean water to the arc channel 24 in the top tray 6.
