Description

Technical Field

[0001] The present invention relates to the technical field of carbon black production equipment, and in particular to a raw material purification device and process for carbon black production. Background Art

[0002] Carbon black is a black powdery substance formed by incomplete combustion or pyrolysis of hydrocarbons in the gas phase under strictly controlled process conditions. Its main component is carbon, and it also contains small amounts of elements such as oxygen, hydrogen and sulfur. The carbon black particles are approximately spherical. Coal is the raw material for carbon black. Coal tar is extracted from coal, and then the coal tar is processed through multiple steps to finally obtain carbon black.

[0003] However, the coal seam is mixed with gangue stones, which contain a small amount of combustibles and are not easy to burn. Therefore, the coal needs to be purified. However, the existing purification treatment device cannot process the gangue on the filter plate in time. When a large amount of gangue is piled together, some tiny gangue particles generated by the collision between the gangue will mix with the coal, resulting in poor coal purification effect.

[0015] A raw material purification process for carbon black production comprises the following steps:

[0016] S1: The raw materials are added to the feed shell, and the driving motor drives the rotating shaft and the spiral blade to rotate.

The raw materials on the feed inclined plate are evenly dispersed onto the curved screen plate through the material distribution guide;

[0021] 2. The raw material purification device and process for carbon black production uses a scraper trough, a reset trough, a scraper, a guide rod, a sliding block, a bottom magnet, a movable frame and a top magnet in combination.

At this time, the scraper can continue to scrape the gangue, so that the device can continuously scrape the gangue, thereby solving the problem that some tiny gangue particles generated by the collision of a large amount of gangue will be mixed with coal.

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] See also Figures 1-8 A raw material purification device for carbon black production includes a mounting frame 1, an outer shell 2 is mounted on the top of the mounting frame 1, a cleaning mechanism 3 is provided in the inner cavity of the outer shell 2, and an arc-shaped sieve plate 11 is provided at the bottom of the cleaning mechanism 3;

[0034] In the above structure, the coal is purified by the arc sieve plate 11. Gangue is solid waste generated during the coal mining process. When the gangue is mixed with coal, the purity of the coal will be impure. Therefore, the coal is purified by the arc sieve plate 11. When the gangue is screened out, the gangue on the arc sieve plate 11 is cleaned by the cleaning mechanism 3 to prevent the gangue from clogging the arc sieve plate 11, so that the device does not need to be shut down to clean the gangue.

[0035] The cleaning mechanism 3 includes a reciprocating screw 301, the outer edge of the reciprocating screw 301 is threadedly connected to a connecting sleeve 302, the outer wall of the connecting sleeve 302 is fixedly equipped with a movable frame 303, the inner wall of the movable frame 303 is slidably connected to a sliding block 304, the bottom of the sliding block 304 is fixedly equipped with a scraper 305, the outer wall of the sliding block 304 is fixedly equipped with a guide rod 306, the inner wall of the guide rod 306 is slidably connected to a scraper trough 309, and the top of the scraper trough 309 is fixedly equipped with a reset groove 310.

[0036] In the above structure, the reciprocating screw rod 301 rotates to drive the connecting sleeve 302, the movable frame 303, the sliding block 304, the guide rod 306 and the scraper 305 to move back and forth. When the movable frame 303 moves to the left, the scraper 305 and the sliding block 304 follow the movable frame 303 to move, and the scraper 305 contacts the curved screen plate 11 and the discharge inclined plate 10. Gradually, the scraper 305 moves the gangue from the curved screen plate 11 to the discharge inclined plate 10. At this time, the guide rod 306 is located in the scraper groove 309. When the movable frame 303 moves to the left, the guide rod 306 will slide in the reset groove 310. At this time, the scraper 305 does not contact the discharge inclined plate 10 and the curved screen plate 11, so that the scraper 305 can return to the initial position to repeatedly scrape off the gangue.

[0037] In a preferred embodiment, a feed inclined plate 8 is provided on the left side of the arc-shaped screen plate 11, a material distribution guide 9 is fixedly mounted on the top of the feed inclined plate 8, and a discharge inclined plate 10 is provided on the right side of the arc-shaped screen plate 11;

[0038] In the above structure, through the setting of the feed inclined plate 8, the gangue and coal can slide on the feed inclined plate 8, and then the gangue and coal are diverted by the dividing guide 9, so that the gangue and coal can slide evenly onto the arc screen plate 11 for filtering, thereby improving the filtering efficiency of the equipment.

[0039] In a preferred embodiment: the inner wall of the top of the moving frame 303 is fixedly equipped with a top magnet 307, and the top of the sliding block 304 is fixedly equipped with a bottom magnet 308;

[0040] In the above structure, through the setting of the top magnet 307 and the bottom magnet 308, when the movable frame 303 moves to the right, the guide rod 306 on the sliding block 304 cooperates with the scraper groove 309 to make the scraper 305 and the sliding block 304 move upward, and the sliding block 304 slides in the inner cavity of the movable frame 303. When the movable frame 303 reaches the rightmost side, the bottom magnet 308 on the sliding block 304 is attracted to the top magnet 307. Then, when the movable frame 303 moves to the left, the guide rod 306 on the sliding block 304 enters the reset groove 310, thereby improving the rationality of the device.

[0041] In a preferred embodiment, the height between the head of the reset groove 310 and the curved screen plate 11 is lower than the height between the tail of the reset groove 310 and the curved screen plate 11, and the reset groove 310 and the scraper groove 309 are both fixedly assembled on the outer shell 2;

[0042] In the above structure, by tilting the reset groove 310, when the movable frame 303 moves to the left, the guide rod 306 slides in the reset groove 310, and gradually the guide rod 306 and the sliding block 304 move downward, so that the bottom magnet 308 and the top magnet 307 can be separated. When the guide rod 306 is located at the head of the reset groove 310, the guide rod 306 will enter the scraper groove 309, so that the scraper 305, the sliding block 304 and the movable frame 303 will scrape the gangue on the curved screen plate 11 again.

[0043] In a preferred embodiment: the shape of the curved screen plate 11 is curved, and the shape of the scraper trough 309 is the same as that of the curved screen plate 11 and the discharge inclined plate 10;

[0044] In the above structure, by setting the shape of the scraper trough 309 to be the same as the shape of the curved screen plate 11 and the discharge inclined plate 10, when the guide rod 306 slides in the scraper trough 309, the guide rod 306 can position the scraper 305, so that the distance between the scraper 305 and the curved screen plate 11 and the discharge inclined plate 10 is always kept consistent, thereby improving the scraping stability of the device.

[0045] In a preferred embodiment, the outer edge of the reciprocating screw 301 is fixedly sleeved with a rotating shaft 4, the outer edge of the rotating shaft 4 is fixedly sleeved with a spiral piece 5, the outer edge of the spiral piece 5 is movably sleeved with a feed shell 6, the feed shell 6 is fixedly assembled on the outer shell 2, the outer wall of the feed shell 6 is fixedly assembled with a drive motor 7, and the rotating shaft 4 is fixedly assembled on the power output shaft of the drive motor 7;

[0046] In the above structure, the rotating shaft 4 and the spiral blade 5 are driven to rotate by the driving motor 7. At this time, the rotating shaft 4 can drive the reciprocating screw 301 to rotate when rotating. The gangue and coal entering the feed shell 6 are evenly transported to the feed inclined plate 8 through the rotation of the spiral blade 5, and then evenly diverted through the material dividing guide 9, further improving the stability of the equipment filtration.

[0047] In a preferred embodiment: a back discharge frame 12 is provided at the bottom of the curved screen plate 11, the back discharge frame 12 passes through the outer shell 2, the discharge port of the back discharge frame 12 is located on the back of the outer shell 2, and a right discharge frame 13 passes through the right side of the outer shell 2;

[0048] In the above structure, through the setting of the back discharge frame 12, when the coal filtered by the arc screen plate 11 falls into the back discharge frame 12, the coal slides through the back discharge frame 12 to the back of the outer shell 2 for accumulation, and the gangue scraped by the scraper 305 will fall into the right discharge frame 13, and the gangue slides through the right discharge frame 13 to the right side of the outer shell 2 for accumulation.

[0049] In a preferred embodiment: a control box 19 is fixedly mounted on the top of the mounting frame 1, and the control box 19 is located on the left side of the outer shell 2. A mounting base 61 is fixedly mounted on the bottom of the feed shell 6, and the mounting base 61 is mounted on the outer shell 2.

[0050] In the above structure, through the setting of the control box 19, the control box 19 is electrically connected to the drive motor 7, and the drive motor 7 can be started and stopped by controlling the control box 19. The mounting bracket 61 supports the feed shell 6 and the drive motor 7, thereby improving the stability of the feed shell 6 and the drive motor 7.

[0051] In a preferred embodiment, a limit rod 14 is fixedly mounted on the bottom of the mounting frame 1. The outer edge of the limit rod 14 is slidably connected to a limit column 15. The bottom of the limit column 15 is fixedly mounted with a base 16. The outer edge of the limit rod 14 is movably sleeved with a support spring 17. A vibration motor 18 is fixedly mounted on the bottom of the mounting frame 1.

[0052] In the above structure, the outer shell 2 is vibrated as a whole by the vibration motor 18, so that the mounting frame 1 and the limiting rod 14 move up and down on the limiting column 15, so that the coal and gangue on the arc screen plate 11 can be separated. The support spring 17 mainly plays a supporting role for the mounting frame 1 and the outer shell 2. When the mounting frame 1 is vibrating, the support spring 17 can limit the shaking amplitude of the mounting frame 1, thereby improving the rationality of the device.

[0053] A raw material purification process for carbon black production comprises the following steps:

[0054] S1: Raw materials are added to the feed housing 6, and the driving motor 7 drives the rotating shaft 4 and the spiral blade 5 to rotate. The spiral blade 5 conveys the raw materials in the feed housing 6 to the feed inclined plate 8. The raw materials on the feed inclined plate 8 are evenly dispersed onto the arc-shaped screen plate 11 through the material distribution guide 9;

[0055] S2: The vibration motor 18 drives the mounting frame 1, the outer shell 2 and the arc-shaped screen plate 11 to vibrate, so that the gangue and coal in the raw material are screened;

[0056] S3: The reciprocating screw 301 is driven to rotate by the rotation of the rotating shaft 4, and the movable frame 303, the sliding block 304, the scraper 305 and the guide rod 306 are driven to move by the rotation of the reciprocating screw 301. The guide rod 306 moves in the scraper trough 309, so that the scraper 305 fits on the arc-shaped screen plate 11 and the discharge inclined plate 10 to move and scrape the gangue, so that the coal is purified.

[0057] Working principle: when in use, gangue and coal are added into the feed shell 6, and the rotation of the driving motor 7 drives the rotating shaft 4 and the spiral blade 5 to rotate. The spiral blade 5 transports the gangue and coal in the feed shell 6, so that the gangue and coal fall onto the feed inclined plate 8, and slide through the feed inclined plate 8 to the material distribution guide 9 for uniform dispersion, and gradually make the gangue and coal fall onto the arc sieve plate 11. The vibration force of the vibration motor 18 drives the arc sieve plate 11 in the outer shell 2 to vibrate, so that the coal falls downward, and the gangue is located above the arc sieve plate 11. The rotating shaft 4 will also drive the reciprocating screw rod 301 to rotate when it rotates, and the rotation of the reciprocating screw rod 301 drives the moving frame 303, the sliding block 304 and the scraper 305 to move to the right. At this time, the scraper 305 and the arc sieve plate 11 and The unloading inclined plate 10 is in contact with each other, and the screened gangue is scraped off by the scraper 305. When the movable frame 303 is located at the rightmost side of the equipment, the gangue is discharged through the right discharge frame 13. The guide rod 306 moves in the scraper trough 309, gradually making the bottom magnet 308 on the sliding block 304 contact with the top magnet 307. The movable frame 303 is located at the rightmost side. When the reciprocating screw rod 301 continues to rotate, it will drive the movable frame 303 to move to the left, and gradually the guide rod 306 enters the reset groove 310 to slide. When the guide rod 306 is located at the head of the reset groove 310, the bottom magnet 308 does not contact the top magnet 307, and the guide rod 306 falls to the head of the scraper trough 309. The reciprocating screw rod 301 can drive the movable frame 303 to move to the right again when rotating.
