Description

Technical Field

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

[0002] Petroleum coke is a byproduct obtained from the petroleum refining process. Its main component is carbon. It is usually used in industrial processes such as manufacturing electrodes and producing aluminum. However, before the above process, petroleum coke needs to be calcined. The purposes of calcining petroleum coke include: 1. Remove volatile substances and other impurities from petroleum coke, thereby increasing its carbon content and making the final product more chemically pure; 2. Control the microstructure of petroleum coke to make it denser, while improving the mechanical strength and conductivity of the material.

[0003] However, before the petroleum coke enters the calcining furnace, large pieces of petroleum coke need to be broken into smaller particles by crushing equipment to increase the surface area of ​​the petroleum coke, promote heat exchange efficiency, and ensure the uniformity of calcination. In this process, the commonly used crushing equipment is the double-roll crusher, which has the following advantages: simple structure, easy operation and maintenance, and convenient replacement of worn parts.

[0004] The double-roll crusher consists of two rollers, a transmission system, a frame and other components. Its working principle is: the two rollers rotate in opposite directions, and the petroleum coke is squeezed and sheared in the gap between the two rollers, so that the petroleum coke is gradually broken into the particle size required for work. However, due to the different shapes of petroleum coke, some long strips of petroleum coke (commonly known as needle coke) are included. When the long strips of petroleum coke fall directly between the two rollers in a flat state, they will slip between the two rollers, thereby reducing the feed amount at this location and even blocking part of the crushing port, which will cause subsequent material unloading difficulties and reduce the crushing efficiency.

DETAILED DESCRIPTION

[0018] Reference to an embodiment herein means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0019] In order to solve the problem of reduced crushing efficiency caused by long strips of petroleum coke blocking the crushing opening during the crushing process of the existing roller crusher, the present invention changes the design of the feeding opening to divide the long strips of petroleum coke and petroleum coke of other particle sizes into different feeding areas, so that some of the long strips of petroleum coke can enter between the two rollers in a non-parallel manner to the rollers, avoiding them from falling flat and blocking the crushing opening, thereby improving the crushing efficiency. In addition, a pre-extrusion method is also adopted to pre-extrude the petroleum coke before it falls into the two rollers, so as to reduce the particle size of the petroleum coke in advance by breaking it, so that the petroleum coke can be more easily and evenly crushed by the two rollers.

[0020] Example 1: A crushing device for calcining petroleum coke, such as Figure 1-Figure 7 As shown, it includes a base frame 10, the base frame 10 is fixedly connected to a crushing box 11, the lower side of the crushing box 11 is fixedly connected and connected to a discharge shell 12, the upper side of the crushing box 11 is fixedly connected and connected to a feed shell 13, and the crushing box 11 is rotatably connected to two symmetrical crushing rollers 14; a driving member 15 is arranged on the base frame 10, and the driving member 15 is used to drive the crushing rollers 14 to rotate; a guide shell 16 is fixedly connected to the crushing box 11, the guide shell 16 is located above the two symmetrical crushing rollers 14, and the guide shell 16 is fixedly connected to a filter plate; symmetrical first guide members 17 are all fixedly connected to the crushing box 11, the symmetrical first guide members 17 are located between the symmetrical crushing rollers 14 and the guide shell 16, and the upper side of the first guide member 17 is set to a rubber material for buffering the falling petroleum coke to prevent the falling petroleum coke from falling. This reduces the generation of smoke and dust; symmetrical second guide members 18 are slidably arranged on the lower side of the guide shell 16, the shape of the second guide member 18 is arc-shaped, the center of the outer arc surface of the second guide member 18 is consistent with the center of the adjacent crushing roller 14, and the distance between the second guide member 18 and the adjacent crushing roller 14 gradually decreases from the side close to the adjacent first guide member 17 to the side away from the adjacent first guide member 17; a plurality of guide grooves 19 are respectively arranged on the upper side of the adjacent first guide member 17, the guide groove 19 is used to guide the petroleum coke, the guide groove 19 is composed of a straight groove and a trapezoidal groove, and the trapezoidal groove of the guide groove 19 is located on the upper side of the straight groove; symmetrical driving components are all arranged on the crushing box 11, and the driving component is used to drive the adjacent second guide member 18 to move.

[0021] In the above scheme, the crushing box 11 is composed of two boxes, and the two boxes are connected by bolts. The box located at the lower side of the crushing box 11 is fixedly connected to the base frame 10. The two boxes in the crushing box 11 are made of high-strength steel alloy. The two crushing rollers 14 are located between the two boxes in the crushing box 11 and rotate with the two. The rotation direction of the two crushing rollers 14 is counter-rotation. There are two driving members 15 in the invention. The driving member 15 is composed of a driving motor and a gearbox. The driving shaft of the driving motor is transmission-connected to the gearbox, and the gearbox is transmission-connected to the adjacent driving member 15. Due to the friction between the two crushing rollers 14 and the petroleum coke, heat will be generated. As the two rotate and squeeze differently, the friction force will continue to act, so the temperature will gradually increase, which will cause the petroleum coke to soften or melt, and then adhere to the outside of the crushing roller 14. Therefore, the staff can add cooling or wind dust removal and liquid dust removal equipment according to actual conditions. The middle part of the filter plate on the guide shell 16 bulges upward, and the guide The upper side of the shell 16 is provided with two inclined surfaces, and the lower side of the guide shell 16 is provided with two arc surfaces. The inclined surface on the upper side of the guide shell 16 is used to guide the petroleum coke to the upper side of the adjacent first guide member 17. The two second guide members 18 are provided with inclined surfaces on the opposite sides. In actual use, the second guide member 18 can be slidably connected to the lower side of the guide shell 16 through a slider, and the upper side of the second guide member 18 is in contact with the adjacent arc surface on the lower side of the guide shell 16, so that the second guide member 18 can slide in the process of sliding. Sliding along the arc surface on the lower side of the guide shell 16, according to the different distances between the second guide members 18 and the adjacent crushing rollers 14, the extrusion pressure of the petroleum coke between the opposite sides of the two second guide members 18 and the two crushing rollers 14 is gradually increased during the rotation of the crushing rollers 14, thereby destroying the overall structural strength of the petroleum coke, so that the petroleum coke can be more easily crushed, and the side with a larger width of the trapezoidal groove on the guide trough 19 is located on the upper side of the straight groove, and the side with a smaller width of the trapezoidal groove on the guide trough 19 is connected to the straight groove.

[0022] like Figure 4-Figure 6 As shown, the driving component includes: an arcuate shell 20, which is fixedly connected to the adjacent first material guide member 17, and the arcuate shell 20 passes through the crushing box 11 and is fixedly connected thereto; a liquid guide member 21, which is fixedly connected to the outer side of the crushing box 11; an arcuate slide bar 22, which is slidably connected to the adjacent arcuate shell 20, the arcuate slide bar 22 passes through the adjacent first material guide member 17 and slidably cooperates with it, and the arcuate slide bar 22 is fixedly connected to the adjacent second material guide member 18; a liquid storage member 23, which is fixedly connected to the adjacent arcuate shell 20, the liquid storage member 23 is fixedly connected to the adjacent arcuate slide bar 22, and the liquid guide member 21 passes through the adjacent arcuate shell 20 and is connected to the adjacent liquid storage member 23.

[0023] In the above scheme, there are two arc shells 20 distributed front and back in the present invention, and the two arc shells 20 are respectively located on the front and rear sides of the crushing box 11, and can actually be an even number, which is used to ensure that the second material guide member 18 can slide stably. The upper side of the first material guide member 17 can be installed with a protective cover for protecting the arc slide bar 22 from collision with petroleum coke. The arc slide bar 22 and the inner side of the adjacent arc shell 20 are non-sealed sliding fits, and the liquid storage member 23 is a bellows sealed at both ends. The central axis of the circle where the arc slide bar 22 is located and the central axis of the circle where the adjacent arc shell 20 is located coincide with the central axis of the adjacent crushing roller 14.

[0024] Before the petroleum coke needs to be crushed, the staff first places the device at the required work site, and then connects the right side of the liquid guide 21 to the pump port of the external gear pump to complete the preparation work before the petroleum coke is crushed.

[0025] After completing the preparatory work before crushing the petroleum coke, the staff starts the two driving members 15, and the two driving members 15 respectively drive the adjacent crushing rollers 14 to rotate, so that the two crushing rollers 14 rotate in opposite directions. Then the staff puts the petroleum coke into the feed shell 13, and the feed shell 13 guides the petroleum coke to the upper side of the guide shell 16. The petroleum coke filtered by the filter plate on the upper side of the guide shell 16 falls into it, and falls along the guide shell 16 into between the two crushing rollers 14, and the two crushing rollers 14 squeeze and crush the petroleum coke.

[0026] The petroleum coke that has not been filtered by the filter plate on the upper side of the guide shell 16 slides to both sides under the guidance of the guide shell 16, and the movement process of all subsequent parts is taken as an example of the rear side. The petroleum coke slides to the rear side to the adjacent first guide member 17 and slides downward along the adjacent guide groove 19. Guided by the trapezoidal groove on the upper side of the guide groove 19, the petroleum coke is regulated to slide downward from the straight groove on the guide groove 19 in a horizontal manner, thereby guiding the petroleum coke. When the petroleum coke slides out of the straight groove on the guide groove 19, the petroleum coke enters the two crushing rollers 14 in a vertical state to crush the petroleum coke.

[0027] When too much petroleum coke accumulates between the second material guide member 18 and the adjacent crushing roller 14, the petroleum coke that is in contact with the lower arc surface of the second material guide member 18 only contacts the lower arc surface of the second material guide member 18 on both sides, while the middle part of the petroleum coke is not in contact with the lower arc surface of the second material guide member 18 at this time. During the continuous rotation of the crushing roller 14, the petroleum coke on its surface is driven to move, so that the crushing roller 14 drives the petroleum coke on the surface to squeeze the middle part of the upper petroleum coke (the upper petroleum coke is: the petroleum coke that is in contact with the lower side of the second material guide member 18), so that the petroleum coke breaks, thereby simulating the way of artificial breaking, reducing the particle size of the petroleum coke, and shortening the time for the petroleum coke to be crushed.

[0028] When blockage still occurs in the crushing box 11 (material unloading is stopped first), the staff injects liquid into the liquid guide part 21 through an external gear pump to increase the pressure inside the adjacent liquid storage part 23, so that the liquid storage part 23 expands and drives the adjacent arc-shaped slide bar 22 to move forward, and the arc-shaped slide bar 22 drives the second material guide part 18 to move forward along the arc surface on the lower side of the material guide shell 16. During the movement of the second material guide part 18, the inclined surface thereon is inserted between the two crushing rollers 14 (at this time, the second material guide part 18 has moved to the required working position), and the petroleum coke blocked between the two crushing rollers 14 is pressed, thereby simulating the way of pressing the petroleum coke with a hand-held shovel to push the petroleum coke between the two crushing rollers 14, thereby alleviating the degree of blockage between the two crushing rollers 14 and reducing the jamming phenomenon caused by the accumulation of petroleum coke, so that the two crushing rollers 14 continue to crush the petroleum coke.

[0029] After the second material guide member 18 moves to the required working position along the lower curved surface of the material guide shell 16, the gear pump extracts the liquid in the liquid guide member 21, so that the pressure in the liquid storage member 23 is reduced, and then the adjacent arc-shaped slide bar 22 is driven to reset and move. The arc-shaped slide bar 22 drives the adjacent second material guide member 18 to reset and move to the rear side. The second material guide member 18 resets and moves to Figure 4 After the state of middle, there is no blockage between the two crushing rollers 14, and the gear pump is no longer in effect.

[0030] The subsequent clearing process can be repeated as described above. When the petroleum coke is no longer needed to be crushed, the staff can close the two driving parts 15.

[0031] Embodiment 2: Based on embodiment 1, Figure 4 , Figure 5 and Figure 7-Figure 9As shown, a plurality of material troughs 30 are provided on the upper part of the second material guide member 18 and on one side close to the material guide shell 16; a sliding plate 31, which is the same in number as the material troughs 30, is slidably connected to the adjacent second material guide member 18 and is located in the adjacent material trough 30; an elastic member 32, which is the same in number as the material troughs 30, is fixedly connected to the second material guide member 18, is located in the adjacent material trough 30, and is fixedly connected to the adjacent sliding plate 31; a connecting pipe 33, which is the same in number as the first material guide member 17, is fixedly connected to the first material guide member 17, runs through the crushing box 11, is slidably connected to the adjacent second material guide member 18 and is communicated with all the elastic members 32 adjacent to one side; a telescopic member 34, which is fixedly connected to the adjacent first material guide member 17; Material piece 17, the telescopic end of the telescopic piece 34 is fixedly connected to the adjacent second material guide piece 18, the telescopic piece 34 is used to protect the adjacent connecting pipe 33, and the second material guide piece 18 is fixedly connected with a plurality of first fixing pins 40 and a plurality of second fixing pins 41 on the side facing the adjacent crushing roller 14 and close to the middle of the material guide shell 16. The first fixing pin 40 corresponds to the adjacent second fixing pin 41 one by one, and the length of the second fixing pin 41 is less than the length of the adjacent first fixing pin 40. The first fixing pin 40 is located between the adjacent second fixing pin 41 and the middle of the adjacent material guide shell 16. The first fixing pin 40 and the adjacent second fixing pin 41 both correspond to the adjacent material guide groove 19 one by one. The second fixing pin 41 is curved and is used to guide the powder, and the curved surface on the upper side of the second fixing pin 41 is nearly straight.

[0032] In the above scheme, the arrangement of several material receiving troughs 30 in the present invention is a linear array, and several material receiving troughs 30 are located on the upper side of the adjacent second material guide member 18 close to the material guide shell 16, so that when the second material guide member 18 is inserted into the blocked petroleum coke, part of the petroleum coke can enter the adjacent material receiving trough 30, thereby reducing the amount of petroleum coke at the blocked position. The elastic member 32 is an elastic liquid capsule, and the telescopic member 34 is a multi-stage telescopic rod, which is used to protect the adjacent connecting pipe 33 from collision with the petroleum coke. The first fixing pin 40 is located below the adjacent second fixing pin 41, and the width of the second fixing pin 41 is consistent with the width of the adjacent first fixing pin 40. Relying on the inner arc surface of the first fixing pin 40, the petroleum coke or powder can slide freely.

[0033] Before crushing the petroleum coke, the outer side of the connecting pipe 33 is first connected to the liquid outlet of the external self-priming pump, and then the crushing steps of Example 1 are repeated.

[0034] During the crushing process of petroleum coke, when the petroleum coke guided by the guide trough 19 moves to contact the adjacent first fixed pin 40, the first fixed pin 40 lifts the petroleum coke, allowing the petroleum coke to enter between the adjacent first fixed pin 40 and the adjacent second fixed pin 41, and then the upper side of the petroleum coke is pressed against the second fixed pin 41. Under the action of the rotation of the adjacent crushing rollers 14, the crushing rollers 14 drive the lower side of the petroleum coke to move, and with the adjacent first fixed pins 40 as the fulcrum, the petroleum coke is actively broken, thereby actively shortening the particle size of the petroleum coke and making it easier to crush. After the petroleum coke is broken, it falls into the two crushing rollers 14 between the two adjacent first fixed pins 40 to achieve secondary processing of the petroleum coke.

[0035] During the process of processing the petroleum coke between the two crushing rollers 14, and when the inclined surface on the second material guide member 18 has been inserted between the two crushing rollers 14 (the adjacent telescopic member 34 is stretched during the movement of the second material guide member 18), the staff reduces the pressure in the connecting pipe 33 through an external self-priming pump, thereby reducing the pressure in all elastic members 32 on the rear side of the connecting pipe 33, and then the elastic member 32 drives the adjacent sliding plate 31 to move downward, so that the surrounding petroleum coke can enter all the material troughs 30 on the rear side. At this time, the liquid in the liquid guide member 21 is extracted by the gear pump to reduce the pressure in the liquid storage member 23 and drive the adjacent arc-shaped slide bar 22 to reset and move. The arc-shaped slide bar 22 drives the adjacent second material guide member 18 to reset and move to the rear side. In the process, the petroleum coke is collected through the material trough 30, simulating the way of manually digging out petroleum coke with a handheld tool to reduce the amount of petroleum coke between the two crushing rollers 14, thereby alleviating the degree of blockage between the two crushing rollers 14.

[0036] During the reset movement of the second material guide 18 (the telescopic part of the telescopic member 34 gradually resets), the external self-priming pump increases the pressure in the connecting pipe 33, thereby increasing the pressure in all the elastic members 32 at the rear side of the connecting pipe 33, and then the elastic members 32 drive the adjacent sliding plates 31 to reset upward, so that the petroleum coke in the material tank 30 can be ejected, thereby facilitating the reset of the second material guide 18. The second material guide 18 resets and moves to Figure 4 When the state is in the middle and there is no longer a blockage between the two crushing rollers 14, the gear pump remains closed.

[0037] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
