Description

Technical Field

[0001] The present invention relates to the technical field of carbon black pulverization, and particularly 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, and inks. The production process of carbon black mainly includes steps such as reaction, cooling, pulverization, and collection. Among them, pulverization is one of the key links to ensure the quality of carbon black products. It not only relates 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 pulverizers for carbon black production on the market are traditional mechanical pulverization equipment. Although these equipment can meet the basic pulverization requirements, some problems have emerged in actual applications: First, most traditional pulverizers lack an effective temperature control mechanism. During the pulverization of carbon black, due to the friction between the high-speed rotating pulverizing parts and the material and the collision of the material itself, a large amount of heat will be generated. If these heats cannot be controlled in a timely and effective manner, the temperature of carbon black may rise, which may cause changes in the properties of carbon black, such as an increase in viscosity and a decrease in fluidity. More seriously, high temperature may also induce the spontaneous combustion or explosion of carbon black, posing a great hidden danger to production safety. Second, there are also obvious deficiencies in the material collection link of traditional carbon black production pulverizers. Most equipment uses a method of directly connecting a cloth bag at 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 operators but also the frequent shutdown and startup will affect the production efficiency and the service life of the equipment. Summary of the Invention

[0004] In view of this, the present invention provides an automatic temperature-controlled pulverizer for carbon black production, which can solve the shortcomings that the existing pulverizers for carbon black production lack an effective temperature control mechanism, resulting in potential safety hazards due to the temperature rise during the pulverization of carbon black, and that the existing pulverizers for carbon black production need to stop the production line to replace the new cloth bag, which is not only troublesome to operate but also affects the production efficiency.

[0035] See Figure 1 and Figure 2As shown in the figure, the feeding mechanism includes a controller 301 and a screw feeder 302. The controller 301 is installed on the upper front side of the support frame 1. The temperature detector 201, the hot and cold air blower 9, and the reduction motor 12 are all electrically connected to the controller 301. A screw feeder 302 is arranged on the upper right side of the closed cylinder 2. The screw feeder 302 is used to feed carbon black into the closed cylinder 2. The controller 301 is electrically connected to the screw feeder 302. The left side of the top of the feeding pipe of the screw feeder 302 is connected to the temperature detector 201.

[0036] See Figures 4 - 6 As shown in the figure, the rotating mechanism includes a servo motor 701, a rotating shaft 702, a frustum 703, and a connecting frame 704. The servo motor 701 is arranged in the middle of the inner bottom of the closed cylinder 2. The servo motor 701 is electrically connected to the controller 301. A rotating shaft 702 is connected to the output shaft of the servo motor 701. Five frustums 703 are arranged at intervals on the rotating shaft 702. The bottoms of the five frustums 703 are respectively rotatably connected to the tops of the five trays 6. Connecting frames 704 are arranged at intervals in a ring shape on the frustum 703. The connecting frames 704 are rotatably connected to the crushing wheels 8.

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

[0038] See Figure 7 and Figure 8 As shown in the figure, the discharging mechanism includes a discharging pipe 1601 and a baffle 1602. The discharging pipe 1601 is communicated with the bottom of the storage frame 10. A baffle 1602 is slidably arranged on the discharging pipe 1601. The baffle 1602 is used to block the inside of the discharging pipe 1601.

[0039] During use, first, the controller 301 controls the temperature detector 201 to detect the temperature inside the closed cylinder 2. Then, the controller 301 controls the servo motor 701 to drive the rotating shaft 702 to rotate, thereby driving the frustum 703, the connecting frame 704, and the crushing wheel 8 to rotate. Next, the controller 301 controls the hot and cold air blower 9 to blow cold air or hot air into the closed cylinder 2, so that the cold air or hot air flows upward from the strip holes 401 of the annular frame 4, thereby enabling the cold air to flow through the connecting pipe 1101 into the storage frame 10. And the temperature detector 201 detects the temperature inside the closed cylinder 2. If the temperature detected by the temperature detector 201 is getting higher and higher, the controller 301 will also control the hot and cold air blower 9 to blow cold air with a lower and lower temperature. If the temperature detected by the temperature detector 201 is getting lower and lower, then the controller 301 will also control the hot and cold air blower 9 to blow hot air with a higher and higher temperature, so as to control the temperature inside the closed cylinder 2 and ensure that the carbon black inside the closed cylinder 2 is within a suitable temperature range (if the temperature of the carbon black is too high, it will cause the interaction force between carbon black particles to increase, making the carbon black more viscous, with poor fluidity, and carbon black is a flammable substance, 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, it will cause the hygroscopicity of the carbon black to possibly increase, absorb moisture in the air, resulting in caking and performance degradation). Then, the controller 301 controls the first air pump 1102 to extract the air inside the connecting pipe 1101 and the closed cylinder 2, so as to accelerate the discharge of the air inside the connecting pipe 1101 and the closed cylinder 2. Next, 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 with the through holes of the storage frame 10 one by one;

[0040] Then, an appropriate amount of carbon black is continuously fed into the closed cylinder 2 by the spiral feeder 302. After the carbon black enters the closed cylinder 2, affected by the cold air or hot air inside the closed cylinder 2, the cold air or hot air will cool or heat the carbon black inside the closed cylinder 2 to ensure that the temperature of the carbon black is within a suitable range and prevent the carbon black from undergoing property changes due to excessive or too low temperature. At the same time, the carbon black will fall downward under the action of gravity onto the uppermost frustum 703, and then the carbon black will slide on the frustum 703 to the annular groove 601 of the uppermost tray 6. After an appropriate amount of carbon black is loaded into the annular groove 601, the excess carbon black will fall downward through 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 onto the next-layer frustum 703, and then the above actions are repeated to disperse the carbon black in the annular grooves 601 of the five trays 6, thereby preventing an excessive amount of 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 roll over 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 blows from bottom to top, when the cold air or hot air flows out from the strip-shaped holes 401 of the annular frame 4, the cold air or hot air will drive the carbon powder in the annular groove 601 to float upward, so that the carbon powder in the closed cylinder 2 will enter the connecting pipe 1101 and the storage frame 10 together with the cold air or hot air. During this period, the first air pump 1102 is used to extract the air in the connecting pipe 1101 and the closed cylinder 2, which can accelerate the floating of the carbon powder in the connecting pipe 1101 and the closed cylinder 2 into the storage frame 10. When the carbon powder enters the storage frame 10, the carbon powder will enter the space in the eight spaces of the rotating frame 13 that is aligned with the through hole. Then, the filter cloth 15 in this space will filter out the carbon powder in the air, so that the carbon powder stays on the filter cloth 15 in this space. When this space rotates to the lower side, the carbon powder on the filter cloth 15 in this space will fall downward under the action of gravity to be collected on the lower side of the storage frame 10. In this way, the automatic crushing of carbon black can be realized, 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; then when it is necessary to discharge the carbon powder in the storage frame 10, pull the baffle 1602 to move leftward, so that the carbon powder in the storage frame 10 falls downward through the discharge pipe 1601 for discharging. In this way, it is convenient for the operator to discharge the carbon powder without the need to stop the machine for discharging operation, which is not only time-saving and labor-saving, but also can improve production efficiency. After the carbon powder in the storage frame 10 is discharged, push the baffle 1602 to move rightward to reset it.

[0041] See Figures 10 - 12As shown in the figure, it further includes a blowing 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 below the rotating shaft 702, and the hollow frame 18 is communicated with the air outlet of the second air pump 17; an air flow channel 19 is provided inside the rotating shaft 702, and the hollow frame 18 is communicated with the air flow channel 19; an annular air outlet pipe 20 is connected to the frustum 703, and 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 communicated with the air flow channel 19 inside the rotating shaft 702. The annular air outlet pipe 20 is used to blow out the carbon powder adhering to the annular groove 601 to prevent the carbon powder from adhering and affecting the subsequent crushing effect.

[0042] During 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 air flow channel 19 inside the rotating shaft 702 into 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 adhering to the annular groove 601 to prevent the carbon powder from adhering and remaining in the annular groove 601.

[0043] See Figures 13 - 15 As shown in the figure, it further includes a cooling mechanism, which includes a water circulation cooling tank 21, a water outlet pipe 22 and a return pipe 23; the water circulation cooling tank 21 is installed at the lower right side of the support frame 1, and the water circulation cooling tank 21 is electrically connected to the controller 301; the water circulation cooling tank 21 is connected to five trays 6 through a water outlet pipe 22; the water circulation cooling tank 21 is connected to five trays 6 through five return pipes 23; an arc-shaped channel 24 is provided inside the tray 6, and the arc-shaped channel 24 is located directly below the annular groove 601, and both the water outlet pipe 22 and the return pipe 23 are communicated with the arc-shaped channel 24.

[0044] See Figure 14 As shown in the figure, it further includes a regulating valve 25; a regulating valve 25 is provided on the return pipe 23, and the regulating valve 25 is used to regulate the flow rate of the clear water in the return pipe 23.

[0045] During use, the controller 301 can be used to control the water circulation cooling tank 21 to introduce clean water into the water outlet pipe 22, so that the clean water flows into the arc-shaped channel 24 in the tray 6 through the water outlet pipe 22. When the clean water enters the arc-shaped channel 24, the heat of the tray 6 will be carried away by the water flow to cool the tray 6 (reason for cooling the tray 6: when the carbon black is pulverized in the annular groove 601, the carbon black will rub against the tray 6 at a distance, resulting in an increase in the temperature of the tray 6), thereby preventing the heat of the tray 6 from being transferred to the carbon black and avoiding excessive temperature of the carbon black. After that, the clean water in the arc-shaped channel 24 will flow back to the water circulation cooling tank 21 through the return pipe 23 for recycling, so as to continuously cool the tray 6; during this period, the flow rate of the clean water in the return pipe 23 can be adjusted through the regulating valve 25, so that the flow rate of the clean water in the return pipe 23 is less than the flow rate of the water in the water outlet pipe 22, so as to ensure that the water outlet pipe 22 can send the clean water into the arc-shaped channel 24 in the uppermost tray 6.

[0046] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered by the protection scope of the present invention.
