Description

Technical Field

[0001] The invention relates to the technical field of drying equipment, and in particular to a petroleum coke crushing and drying processing device. Background Art

[0002] Petroleum coke is a product obtained by separating the light and heavy oils from crude oil through distillation and then thermally cracking the heavy oil. It is a black or dark gray solid coke, mainly composed of carbon, and also contains a small amount of impurities such as hydrogen, nitrogen, sulfur and metals. Commonly used crushing equipment includes jaw crushers, cone crushers, impact crushers and other coarse crushing equipment, which are used to crush large pieces of petroleum coke into smaller particles. For further fine crushing, ball mills, rod mills and other equipment can be used;

[0003] The utility model with application number 202022114527.3 discloses a petroleum coke crushing and drying device. By setting a filter plate, a coarse material outlet, a collecting trough, a rotating rod and a fan blade, when the petroleum coke is poured into the feed hopper, the two second motors are started, and the two crushers start to work to crush the petroleum coke. The petroleum coke that meets the crushing standard will pass through the filter plate to the guide trough. The user opens the sealing plate by rotating the shaft, and the petroleum coke that is not crushed thoroughly flows into the collecting trough through the inclined coarse material outlet. The electric push rod is started, and the electric push rod pushes the collecting trough upward to the coarse material inlet. The petroleum coke that is not crushed thoroughly enters the crusher for crushing again, and the crushing cycle is repeated until all the petroleum coke passes through the filter plate, and all the crushed petroleum coke enters the drying cylinder through the guide trough. The blower and the first motor are started, and the blower dries the petroleum coke in the drying cylinder. The motor drives the rotating rod to rotate, and the rotating rod drives the fan blades on both sides to move. The fan blades move the petroleum coke to prevent accumulation, so that all the petroleum coke in the drying cylinder is fully dried, and the petroleum coke is finally discharged from the discharge port.

[0004] However, when a blower is used for drying in the above-mentioned petroleum coke crushing and drying device, it is easy to cause the crushed petroleum coke to reversely enter the material guide trough and be blown out from the coarse material outlet, affecting normal operation. When drying in the above-mentioned petroleum coke crushing and drying device, only the temperature at the blower outlet is high enough to achieve rapid drying, while the temperature at other positions is low and uniform drying cannot be achieved. After the blower is stopped, the petroleum coke powder is easy to fall into the blower and cause equipment damage. Therefore, the present invention proposes a petroleum coke crushing and drying processing device to solve the problems existing in the prior art. Summary of the invention

[0019] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with examples. The examples are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0020] Petroleum coke needs to be crushed in many application scenarios. For example, when producing prebaked anodes for aluminum, crushing the petroleum coke to a suitable particle size can increase its specific surface area, which is conducive to subsequent uniform mixing with binders, thereby improving the quality of the prebaked anode. When manufacturing graphite electrodes, the crushed petroleum coke can better cooperate with other raw materials to ensure the performance of the electrode. The particle size of the crushed petroleum coke is usually controlled according to the specific production process and product requirements. The drying of petroleum coke is mainly to remove the moisture in it. The presence of moisture may affect the performance of petroleum coke in subsequent processing.

[0021] Based on this, according to Figure 1 , Figure 2 , Figure 3 As shown, this embodiment provides a petroleum coke crushing and drying processing device, including a drying cylinder 1, a uniform drying mechanism, a uniform feeding mechanism and a crushing mechanism. The uniform drying mechanism includes a heating interlayer 2, an electric heating pipe 3, a feed port 4, a discharge port 5, an exhaust pipe 6, a filter bin 7 and a dust filter. The drying cylinder 1 is sandwiched with a heating interlayer 2, and the heating interlayer 2 is surrounded and fixed with an electric heating pipe 3. The upper side of the drying cylinder 1 is connected to the feed port 4, and the lower side of the other side of the drying cylinder 1 is connected to the discharge port 5. The middle of the upper part of the drying cylinder 1 is connected to the exhaust pipe 6, and the exhaust pipe 6 is connected to the filter bin 7. The filter bin 7 is fixed with a dust filter. The net is used for heating and drying, and the evaporated water is discharged upward through the exhaust pipe 6. When passing through the filter bin 7, the dust is blocked by the dust-proof filter net. There are multiple groups of electric heating tubes 3 around it. The top of the filter bin 7 is open. When the petroleum coke is crushed, it falls freely into the drying cylinder 1. The electric heating tube 3 is powered on to heat the inside of the drying cylinder 1, and the temperature is increased to dry the petroleum coke powder, which effectively prevents the problem of dust flying caused by the use of a blower to dry. At the same time, multiple groups of heating tubes are used for surrounding heating to achieve uniform heating and drying of the petroleum coke powder. A uniform feeding mechanism is provided in the drying cylinder 1, and a crushing mechanism is provided on the upper side of the drying cylinder 1.

[0022] The uniform speed feeding mechanism includes a first motor 8, a feeding screw shaft 9 and a scraper bar 10. The first motor 8 is fixedly provided on one side outside the drying cylinder 1, and a feeding screw shaft 9 is rotatably provided inside the drying cylinder 1. The output end of the first motor 8 is drivingly connected to the feeding screw shaft 9. The feeding screw shaft 9 is symmetrically fixed with scraper bars 10 up and down, and the scraper bars 10 are in contact with the inner wall of the drying cylinder 1. When heating and drying are carried out, the first motor 8 starts to drive the feeding screw shaft 9 to rotate to flip the petroleum coke powder while pushing it to the other side of the drying cylinder 1, so as to facilitate the full drying of the petroleum coke powder. At the same time, the scraper bar 10 rotates synchronously with the feeding screw shaft 9 to prevent the powder from sticking to the inner wall of the drying cylinder 1.

[0023] The crushing mechanism includes a crushing box 11, a rotating block 12, a discharging slope 13, a crushing slope 14, a fixed block 15 and a lifting drive mechanism. The crushing box 11 is fixedly provided on one side of the drying cylinder 1. A rotating block 12 is rotatably provided on the top of the crushing box 11. A discharging slope 13 is inclined above the rotating block 12. A crushing slope 14 is inclined below the rotating block 12. A fixed block 15 is fixed around the top of the crushing box 11. The inner side of the fixed block 15 is close to the rotating block 12. A lifting drive mechanism is provided in the middle of the crushing box 11. The lifting drive mechanism includes a bracket 16, an electric telescopic rod 17, a lifting plate 18, a second motor 19, a guide slide 20 and a slider 21. A bracket 16 is fixedly provided in the middle of the top of the crushing box 11. Electric A lifting plate 18 is fixedly arranged at the telescopic end of the electric telescopic rod 17, a second motor 19 is fixedly arranged in the middle above the lifting plate 18, a guide slide 20 is symmetrically provided on the inner side of the bracket 16, and a slider 21 is fixedly provided on the lifting plate 18 symmetrically front and back. The output end of the second motor 19 is drive-connected with the rotating block 12, and the slider 21 is slidably matched with the guide slide 20. When crushing is performed, the second motor 19 drives the rotating block 12 to rotate at the top of the crushing box 11 and cooperates with the fixed block 15 to perform friction crushing. When the degree of crushing needs to be adjusted, the electric telescopic rod 17 is extended and retracted to drive the lifting plate 18 to move and drive the rotating block 12 to rise and fall synchronously. The degree of crushing is adjusted by adjusting the distance between the rotating block 12 and the fixed block 15, which is convenient for quick adjustment according to needs.

[0024] A feed hopper 22 is connected to one side of the crushing box 11, and a slide groove 23 is symmetrically opened in the middle of the feed hopper 22. A dust shield 24 is slidably inserted between the slide grooves 23. When crushing is performed, the dust shield 24 is inserted into the feed hopper 22 along the slide groove 23 to prevent dust from flying.

[0025] A sub-screen 25 is fixedly installed in the crushing box 11 at an angle. A coarse material pipe 26 is connected to one side of the crushing box 11. The coarse material pipe 26 is located above one side of the sub-screen 25. The crushed petroleum coke powder falls freely and is screened by the sub-screen 25. The coarse material with larger particles rolls out through the coarse material pipe 26.

[0026] When the petroleum coke crushing and drying device is used for processing, the petroleum coke is poured into the crushing box through the feed hopper, and the electric telescopic rod is extended and retracted to drive the lifting plate and the rotating block to lift and lower to adjust the gap distance between the rotating block and the fixed block. When crushing, the dust shield is inserted into the feed hopper along the slide slot to prevent dust. The second motor drives the rotating block to rotate and cooperates with the fixed block for friction to crush. The crushed powder falls freely onto the sieve for sieving. The powder with larger particles rolls out through the coarse material pipe, and the qualified powder falls into the drying cylinder. The electric heating tube is energized to generate heat to evenly heat the inside of the drying cylinder. At the same time, the first motor drives the feeding spiral shaft to rotate, and pushes the powder to the other side of the drying cylinder while turning the powder. The dried evaporated water is discharged through the exhaust pipe, and the accompanying dust is filtered by the filter bin, so that the dried water can evaporate stably. After drying, the petroleum coke powder is discharged through the discharge port.
