Description

Technical Field

[0001] This utility model relates to the field of carbon black processing technology, and more specifically, it relates to a coarse carbon black magnetic separator. Background Technology

[0002] Carbon black is a black powder produced by the incomplete combustion or thermal cracking of hydrocarbons in the gas phase. It is often used as a reinforcing agent and filler in rubber processing. The produced carbon black often contains a large number of metallic impurities, which can affect the use of carbon black. Therefore, the crude carbon black needs to be magnetically separated to remove these impurities.

[0003] Most common magnetic separators have a simple structure, using the adsorption effect of a magnetic conveyor belt to attract impurities and transport the separated carbon black material out. However, in actual use, coarse carbon black is poured into the equipment in stages during the feeding process. At this time, the carbon black material mainly clumps together, forming multiple piles during magnetic separation, rather than being evenly spread. On the one hand, there will be idle parts of the magnetic conveyor; on the other hand, the impurities inside the piled material are not easily attracted out, affecting the magnetic separation capacity. Moreover, the amount of material added during feeding is controlled by the operator's sense of feeling. If the amount added is not matched with the movement speed of the magnetic conveyor, too much material will cause the carbon black to pile up, affecting the magnetic separation of internal impurities. If too little material is added, the equipment will not work efficiently, and the magnetic separation work will be wasted. In addition, some fine impurities in the coarse carbon black material may also adhere to the surface of the carbon black material, sticking to the carbon black particles and forming clumps, affecting the removal of impurities and affecting the quality and efficiency of magnetic separation.

[0030] Please see Figure 1-5 A coarse carbon black magnetic separator includes a housing 1, a magnetic separation conveyor belt 2 inside the housing 1, a processing frame 3 at the upper part of the housing 1, a feeding plate 4 at the lower end of the processing frame 3, a drive motor 5 at the upper end of the housing 1, a rotating shaft 6 at the output end of the drive motor 5, a main agitator 7 on the rotating shaft 6, a secondary shaft 8 rotatably connected inside the housing 1, a secondary agitator 9 at the lower end of the secondary shaft 8, and a set of matching wheels 10 on the rotating shaft 6 and the secondary shaft 8.

[0031] The feeding plate 4 has a feeding port 11, and a baffle plate 12 is provided in the feeding port 11. The baffle plate 12 is rotatably engaged with the feeding plate 4. The outer end of the box 1 is provided with a control motor 13. One end of the control motor 13 is provided with a reducer 14. The reducer 14 is provided with a drive shaft 15, which is engaged with the baffle plate 12.

[0032] In this embodiment, the space provided by the housing 1 is used to load the coarse carbon black material into the equipment. The coarse carbon black is supported by the processing frame 3, and the material is passed through the feeding plate 4 at a certain speed, causing the material to fall. When the coarse carbon black is above the feeding plate 4, the drive motor 5 is controlled to work, so that the drive motor 5 drives the main stirring plate 7 to rotate through the rotating shaft 6. When the rotating shaft 6 rotates, it will cause the secondary shaft 8 to rotate together through the transmission of the cooperating wheel group 10, which will drive the surrounding stirring plates to rotate. Through the cooperation of the main stirring plate 7 and the secondary stirring plate 9, the material on the feeding plate 4 is pushed and stirred, so that the agglomerated material becomes loose and the material is spread to the surrounding area and evenly spread on the feeding plate 4, so that the material passing through the feeding plate 4 falls more evenly.

[0033] More specifically, when there is material on the feeding plate 4, the material will fall from the feeding port 11, and the baffle plate 12 will block the feeding port 11, controlling the falling of the material in the feeding port 11. The control is achieved by the motor 13 providing power, and under the adjustment of the reducer 14, the baffle plate 12 is controlled to rotate through the drive shaft 15, so that the baffle plate 12 is at different amplitudes, controlling the exposed area of ​​the feeding port 11, thereby adjusting the falling speed of the material.

[0034] Please see Figure 3 and Figure 4As one method of material dispersion: a guide plate 16 is provided below the processing frame 3. One end of the guide plate 16 is rotatably connected to the box body 1. A telescopic drive rod 17 is provided on the box body 1. A drive frame 18 is provided at the output end of the telescopic drive rod 17. A support wheel 19 is rotatably connected in the drive frame 18. The support wheel 19 cooperates with the guide plate 16.

[0035] Specifically, after the coarse carbon black falls from the feed plate 4, it falls onto the guide plate 16. Guided by the guide plate 16, the material is guided to the inside of the magnetic separation conveyor belt 2, so that the magnetic separation conveyor belt 2 can carry out magnetic separation while transporting the material. As the material falls along the guide plate 16, the drive frame 18 is moved by the telescopic drive rod 17. The drive frame 18 cooperates with the guide plate 16 through the support wheel 19. Under the repeated drive of the telescopic drive rod 17, the support wheel 19 moves repeatedly, pushing the guide plate 16 to rotate. The guide plate 16 vibrates the coarse carbon black, which disperses the material and facilitates subsequent magnetic separation.

[0036] Please see Figure 3 and Figure 4 As a further embodiment of the drive frame: the drive frame 18 is provided with support sliders 20 at both ends, and the housing 1 is provided with support grooves 21 at both ends, and the support sliders 20 and the support grooves 21 are slidably engaged.

[0037] Specifically, when the drive frame 18 moves, the cooperation between the support slider 20 and the support groove 21 provides additional support and movement restriction, making the movement of the drive frame 18 more stable.

[0038] Please see Figure 4 As a further embodiment of the guide plate: a wheel groove 22 is provided at the lower end of the guide plate 16, and the wheel groove 22 cooperates with the support wheel 19.

[0039] Specifically, the groove 22 cooperates with the support wheel 19 to limit contact with the support wheel 19, making the cooperation more stable.

[0040] Please see Figures 1-3 As a further implementation of the enclosure: a ventilation opening 23 is provided at one end of the enclosure 1, and a fan 24 is provided inside the enclosure 1, with the fan 24 cooperating with the ventilation opening 23.

[0041] Specifically, the ventilation port 23 provides a gas flow structure, and the fan 24 provides negative pressure to blow air into the interior. When the material falls from the guide plate 16, the lighter impurities in the coarse carbon black are blown away, so that the impurities and coarse carbon black material are separated, which facilitates subsequent magnetic separation.

[0042] Please see Figure 1 As a further embodiment of the box body: the upper end of the box body 1 is provided with a feed inlet 25 and the lower end is provided with a discharge outlet 26.

[0043] Specifically, the material enters through the feed inlet 25 and is discharged through the discharge outlet 26.

[0044] Please see Figure 3 As a further embodiment of the processing frame: the outer end of the processing frame 3 is provided with a guide slope 27.

[0045] Specifically, when adding materials, the materials are guided by the guide slope 27 to converge on the downward material plate 4.

[0046] Please see Figure 2 and Figure 5 As a further embodiment of the baffle plate: a drive shaft 28 is provided on the side end of the baffle plate 12, a drive wheel 29 is provided on the drive shaft 28, and a drive belt 30 is provided between the drive wheels 29.

[0047] Specifically, when controlling the rotation of the baffle plate 12, the transmission of the transmission shaft 28 and the cooperation between the transmission wheel 29 and the transmission belt 30 enable multiple sets of baffle plates 12 to rotate synchronously, which facilitates the adjustment of the amplitude state.

[0048] In summary, during the use or operation of the overall equipment:

[0049] When using the equipment, connect it to an external power source. The housing 1 provides space, and the coarse carbon black material is added into the housing 1 through the feed inlet 25. Supported by the processing frame 3 and guided by the guide slope 27, the material converges onto the feed plate 4. The feed plate 4 supports the coarse carbon black, and the material passes through the feed plate 4 at a certain speed, causing the material to fall. When the coarse carbon black is above the feed plate 4, the drive motor 5 is activated, driving the main agitator 7 to rotate via the rotating shaft 6. As the rotating shaft 6 rotates, it transmits power through the gear set 10, causing the secondary shaft 8 to rotate as well, rotating the surrounding agitator plates. Through the cooperation of the main agitator 7 and the secondary agitator 9, the material on the feed plate 4 is pushed and agitated, loosening any clumps and spreading the material evenly onto the feed plate 4, ensuring a more uniform fall of the material passing through the feed plate 4.

[0050] When there is material on the feeding plate 4, the material will fall from the feeding port 11. The baffle plate 12 will block the feeding port 11, controlling the falling of the material in the feeding port 11. The control is achieved by the motor 13 providing power. Under the adjustment of the reducer 14, the baffle plate 12 is controlled to rotate through the drive shaft 15. When the baffle plate 12 rotates, multiple baffle plates 12 rotate synchronously through the transmission of the drive shaft 28 and the cooperation between the drive wheel 29 and the drive belt 30. This allows for the adjustment of the amplitude state, so that the baffle plate 12 is in different amplitudes, controlling the exposed area of ​​the feeding port 11, thereby adjusting the falling speed of the material.

[0051] After the coarse carbon black falls from the feed plate 4, it lands on the guide plate 16. Guided by the guide plate 16, the material is directed towards the inside of the magnetic separation conveyor belt 2, allowing the conveyor belt 2 to perform magnetic separation while transporting the material. As the material falls along the guide plate 16, the drive frame 18 moves under the control of the telescopic drive rod 17. The drive frame 18, through the cooperation of the support slider 20 and the support groove 21, provides additional support and movement restraint, making the drive frame 18 move more stably. The support wheel 19 cooperates with the guide plate 16. The support wheel 19 is inserted into the groove 22 for stable engagement. Under the repeated drive of the telescopic drive rod 17, the support wheel 19 moves repeatedly, pushing the guide plate 16 to rotate. The guide plate 16 vibrates the coarse carbon black, dispersing the material. The ventilation port 23 provides a gas flow structure, and the fan 24 provides negative pressure to blow air into the interior. When the material falls from the guide plate 16, the lighter impurities in the coarse carbon black are blown away, so that the impurities and coarse carbon black material are separated, which facilitates subsequent magnetic separation. Under the transportation of the magnetic separation conveyor belt 2, the material is discharged from the outlet 26.

For all the fixed connections mentioned above, welding is preferred.
