[0026] In the description of this embodiment, the orientation or positional relationships such as "upper", "lower", "left", "right", etc. are based on the orientation or positional relationships shown in the drawings. These are only for convenience of description and simplifying the operations, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation.

In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0027] Please refer to Figures 1 to 3 , the present utility model provides a technical solution: a needle coke anti-breakage conveying device, which includes a protective housing 1 and a conveying component 2. The conveying component 2 is arranged inside the protective housing 1, and the conveying component 2 is in an outer spiral shape;
[0028] The protective housing 1 is configured to prevent foreign objects from falling on the conveying component and contaminating the needle coke;
[0029] The conveying component 2 includes an inlet section chute 21, a plurality of intermediate section chutes 22, and an outlet section chute 23. The inlet section chute 21, the plurality of intermediate section chutes 22, and the outlet section chute 23 are connected in sequence from top to bottom, and buffer section chutes 24 are arranged at the connection parts between the inlet section chute 21, the plurality of intermediate section chutes 22, and the outlet section chute (23). The buffer section chute plays a good buffering role in the conveying of needle coke: one is to change the conveying direction of the needle coke, and while changing the conveying direction of the needle coke, it absorbs a certain amount of energy, thereby reducing the speed of the needle coke and preventing the needle coke from being damaged due to too high a speed; the other is that the buffer section chute is made of high molecular materials such as polyurethane, plastic, rubber, etc. Compared with the traditional steel chute, the high molecular material has a certain flexibility and has a good protective effect on the needle coke.
[0030] In a specific embodiment, the protective housing 1 includes a straight cylinder section 11 and an inverted cone cylinder section 12. The conveying component 2 is located inside the straight cylinder section 11, and the inverted cone cylinder section 12 is configured as the outlet section of the needle coke; specifically, the inverted cone cylinder section has a converging effect, which is conducive to the collection of the needle coke, and the inverted cone cylinder section changes the direction of the needle coke conveyed obliquely downward to obliquely upward, further slowing down the falling speed of the needle coke, and effectively solving the problem that the needle coke is easily broken due to too high a speed.
[0031] In a specific embodiment, the inlet section chute 21 includes a straight section chute 211 and an arc section chute 212, and the straight section chute 211 and the arc section chute 212 are tangentially connected.
[0032] In a specific embodiment, the inlet section chute 21, the plurality of intermediate section chutes 22, and the outlet section chute 23 are steel chutes, and the buffer section chute 24 is a polyurethane chute.
[0033] In a specific embodiment, the hardness of the inlet chute 21, the plurality of intermediate chutes 22, and the outlet chute 23 is 350 HV 0.2 -500 HV 0.2 , and the Shore hardness of the buffer chute 24 is 30A - 90A; specifically, the steel plates used for the steel chute are NM350, NM400, NM450, NM500, etc., where "NM" indicates wear resistance; the relatively soft polyurethane of the buffer chute greatly reduces the collision force of the needle coke, but the hardness of the polyurethane should not be too low. If the hardness is too low, the speed of the needle coke will be greatly reduced after collision, affecting the conveying speed and efficiency of the needle coke. Preferably, the Shore hardness of the buffer chute 24 is 50A - 90A, and specifically, it can be 50A, 60A, 70A, 80A, 90A, etc.
[0034] In a specific embodiment, the intermediate chute 22 is a standard chute. The outer spiral diameter of the standard chute is 500 mm - 5000 mm, the outer spiral inclination angle of the standard chute is 24° - 29°, and the spiral bottom plate inclination angle of the standard chute is 22° - 28°; specifically, the outer spiral diameter of the standard chute is 500 mm, 1000 mm, 1500 mm, 2000 mm, 2500 mm, 3000 mm, 3500 mm, 4000 mm, 4500 mm, 5000 mm, etc., the outer spiral inclination angle of the standard chute is 28°, and the spiral bottom plate inclination angle of the standard chute is 26°.
[0035] In a specific embodiment, please refer to Figure 2 , the pitch h of the standard chute is not greater than 500 mm.
[0036] In a specific embodiment, please refer to Figure 2 , the pitch h of the standard chute is not greater than 300 mm; specifically, the pitch h of the standard section is selected as 100 mm, 150 mm, 200 mm, 250 mm, 300 mm. Limiting the height of the pitch can prevent the height difference of the needle coke from falling too large, resulting in too high a conveying speed of the needle coke and reducing the impact speed of the needle coke in the buffer chute.
[0037] In a specific embodiment, please refer to Figure 3 , the end of the outlet chute 23 is a straight chute, and the angle A between the plane where the end of the outlet chute 23 is located and the tangent plane of the inverted cone section 12 of the protective housing 1 is not greater than 3°; preferably, the angle A is greater than 0° and less than or equal to 2°; more preferably, the angle A is greater than 0° and less than or equal to 1°. Such a design is beneficial to preventing damage caused by the vertical impact on the inverted cone section during the conveying process of the needle coke.
[0038] In a specific embodiment, the outlet of the outlet chute 23 faces the barrel wall of the inverted cone section 12, and a detachable polyurethane protection plate is provided on the barrel wall of the inverted cone section 12 at the outlet of the outlet chute 23; exemplarily, the detachable polyurethane protection plate can be connected to the inverted cone section by bolts or can be detachably connected by means of plugging; at the same time, the detachable polyurethane protection plate is made of the same polyurethane material as the aforementioned buffer chute, and has the same Shore hardness.
[0039] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
