Description

Technical Field

[0001] This utility model relates to the field of petroleum coke calcination technology, specifically to a petroleum coke calcination conveying device. Background Technology

[0002] Petroleum coke is a product obtained by separating light and heavy oils from crude oil through distillation, and then further converting the heavy oils through thermal cracking.

[0003] Petroleum coke is typically fed into rotary kilns or cauldrons via belt conveyors for calcination. Belt conveyors rely on the friction between the petroleum coke and the belt surface for transport. However, irregular vibrations or shaking can occur during transport, causing petroleum coke to fall from the sides of the belt to the ground, resulting in waste. Furthermore, since the feed inlets of rotary kilns and cauldrons are at a certain height, the belt conveyor needs to be modified to parallel or inclined conveying, requiring the pre-installation of support components, which is a rather cumbersome process. Utility Model Content

[0004] The purpose of this invention is to provide a petroleum coke calcination conveying device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a petroleum coke calcination conveying device, comprising a base, two lifting plates symmetrically mounted on the upper end of the base, a positioning shaft mounted on one end of each of the two lifting plates facing each other, a belt conveyor mounted between the two positioning shafts, a bottom plate mounted on each side of the belt conveyor, a side plate mounted on each side of the bottom plate, a baffle plate rotatably connected between the two side plates via a common pivot, two second grooves symmetrically formed on the upper end of each side plate, two first grooves symmetrically formed on the side of the baffle plate facing the bottom plate, a second rotating block rotatably connected to the upper side inside the first groove via two pivots, a first rotating block rotatably connected to the outer side inside the second groove via two pivots, and a driven multi-section telescopic rod mounted between the first rotating block and the second rotating block.

[0006] Preferably, each of the two side plates has an arc-shaped guide groove at one end facing each other, and a guide shaft is installed on both sides of the barrier plate, with the two guide shafts slidably connected to the two arc-shaped guide grooves respectively.

[0007] Preferably, the end of the arc-shaped guide groove near the belt conveyor is a closed opening.

[0008] Preferably, a telescopic push plate is installed at one end of the base, and a movable plate is installed at the other end of the telescopic push plate. The lower end of the movable plate is slidably connected to the extension plate via a guide rail.

[0009] Preferably, a fixing plate is fixedly installed on the outer side of each of the two base plates, and a third rotating block is rotatably connected to the inner side of the fixing plate via a rotating shaft. The third rotating block is connected to the belt conveyor via the rotating shaft.

[0010] Preferably, two mounting slots are symmetrically installed on the upper end of the movable plate, and a fourth rotating block is rotatably connected inside the mounting slots via two rotating shafts. A hydraulic rod is installed between the fourth rotating block and the third rotating block.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. The petroleum coke calcination conveying device of this utility model has rotatable baffles on both sides of the belt conveyor. When the amount of petroleum coke conveyed above the belt is large, it will move towards the baffles on both sides, thereby producing a certain squeezing effect on the baffles. The baffles will flip outward according to the pressure, and can completely block the petroleum coke inside the belt conveyor, preventing the petroleum coke from falling from above the belt conveyor.

[0013] 2. The petroleum coke calcination conveying device of this utility model has a telescopic hydraulic rod installed at the lower end of the belt conveyor. The hydraulic rod can drive the belt conveyor to lift to a certain height, and the belt conveyor will rotate at a certain angle around the positioning shaft. This allows the belt conveyor to change from a parallel state to an inclined state according to the extension and retraction length of the hydraulic rod, so as to meet the conveying requirements at different angles.

In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] like Figures 1 to 3As shown, the petroleum coke calcination conveying device of this embodiment includes a base 1. Two lifting plates 8 are symmetrically installed on the upper end of the base 1. The lifting plates 8 are hydraulic devices with lifting functions, and can be raised and lowered at a certain angle. A positioning shaft 9 is installed at one end of the two lifting plates 8 facing each other. A belt conveyor 7 is installed between the two positioning shafts 9. The positioning shafts 9 are fixedly connected to the lifting plates 8 and rotatably connected to the belt conveyor 7. The belt conveyor 7 is a relatively mature existing technology and will not be described in detail. A base plate 14 is installed on both sides of the belt conveyor 7. The base plate 14 is fixedly connected to the belt conveyor 7. A side plate 10 is installed on both sides of the base plate 14. A baffle plate 13 is rotatably connected between the two side plates 10 through a common pivot. The baffle plate 13 is rotatably connected to the two side plates 10. When subjected to external pressure, the baffle plate 13 will rotate at a certain angle. Two second grooves 16 are symmetrically opened on the upper end of the side plates 10. Two first grooves 15 are symmetrically formed on one side facing the base plate 14. A second rotating block 19 is rotatably connected to the upper side of the inside of the first groove 15 via two rotating shafts. A first rotating block 18 is rotatably connected to the outer side of the inside of the second groove 16 via two rotating shafts. The second rotating block 19 can rotate inside the first groove 15, and the first rotating block 18 can rotate inside the second groove 16. A driven multi-section telescopic rod 17 is installed between the first rotating block 18 and the second rotating block 19. A spring is installed inside the driven multi-section telescopic rod 17. Under normal conditions, the driven multi-section telescopic rod 17 will support the baffle plate 13, and the baffle plate 13 will be in a vertical state. When the petroleum coke at the upper end of the belt conveyor 7 exerts pressure on the baffle plates 13 on both sides, the baffle plate 13 will flip according to the magnitude of the pressure, thereby driving the driven multi-section telescopic rod 17 to retract synchronously. It should be noted that the baffle plate 13 can only flip within a certain range and cannot be completely flipped to a parallel state.

[0021] Specifically, each of the two side plates 10 has an arc-shaped guide groove 11 at one of its facing ends, and a guide shaft 12 is installed on each side of the barrier plate 13. The two guide shafts 12 are slidably connected to the two arc-shaped guide grooves 11 respectively. When the barrier plate 13 is flipped, the two guide shafts 12 will move inside the two arc-shaped guide grooves 11 respectively. The arc-shaped guide grooves 11 can limit and guide the flipping trajectory of the barrier plate 13.

[0022] Furthermore, the end of the arc-shaped guide groove 11 near the belt conveyor 7 is a closed opening. The closed opening can block the movement of the guide shaft 12, thereby limiting the flipping of the baffle plate 13. When the guide shaft 12 contacts the closed opening, the baffle plate 13 is in a vertical state.

[0023] Furthermore, a telescopic push plate 3 is installed at one end of the base 1, and a movable plate 4 is installed at the other end of the telescopic push plate 3. The lower end of the movable plate 4 is slidably connected to the extension plate 2 via a guide rail. The telescopic push plate 3 is a hydraulic plate, which can drive the movable plate 4 to slide on the surface of the extension plate 2. It should be noted that the bottom of the extension plate 2 can be equipped with a moving device, such as a locking caster wheel, according to the user's needs.

[0024] Furthermore, a fixed plate 22 is fixedly installed on the outer side of each of the two base plates 14. A third rotating block 20 is rotatably connected to the inner side of the fixed plate 22 via a rotating shaft. The third rotating block 20 is connected to the belt conveyor 7 via a rotating shaft. Two mounting slots 5 are symmetrically installed on the upper end of the movable plate 4. A fourth rotating block 21 is rotatably connected to the inside of the mounting slots 5 via two rotating shafts. A hydraulic rod 6 is installed between the fourth rotating block 21 and the third rotating block 20. By extending and retracting the hydraulic rod 6, the distance between the belt conveyor 7 and the movable plate 4 can be changed. In conjunction with the positioning shaft 9 rotatably connected to the belt conveyor 7, the angle of the belt conveyor 7 can be changed, making the belt conveyor 7 an inclined device, thereby meeting the conveying requirements of different height inlets of different devices. The movable plate 4 can move horizontally. When the movable plate 4 moves, in conjunction with the extension and retraction of the hydraulic rod 6, the tilt angle of the belt conveyor 7 can also be changed.

[0025] The usage method of this embodiment is as follows: depending on the calcination equipment, first adjust the position of the moving plate 4 and the length of the hydraulic rod 6 so that the highest point of the belt conveyor 7 is above the feed inlet of the calcination equipment. At this time, petroleum coke is fed from the bottom of the belt conveyor 7 to the belt surface. The petroleum coke will be conveyed by the belt conveyor 7. When the amount of petroleum coke conveyed above the belt is large, it will move to the two side baffles 13, thereby producing a certain squeezing effect on the baffles 13. The baffles 13 will flip outward according to the pressure and can completely block the petroleum coke inside the belt conveyor 7, preventing the petroleum coke from falling from above the belt conveyor 7.

[0026] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
