[0016] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0017] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0018] When used herein, the singular forms of “a,” “an,” and “the” may also include the plural forms unless the context clearly indicates otherwise. It should also be understood that the terms “comprising,” “including,” or “having,” etc., specify the presence of the stated feature, whole, step, operation, component, part, or combination thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof.

[0019] Example 1 A continuous, closed, integrated screen and crusher structure for decoking includes a roller screen assembly 1 and a crushing assembly 2. The roller screen assembly 1 has a feed end 16 at one end and a discharge end 17 at the other end. The roller screen assembly 1 includes a plurality of parallel screen shafts 11 arranged sequentially from the feed end 16 to the discharge end 17. Each screen shaft 11 is uniformly fitted with a plurality of screen discs 12 along the axial direction. Each screen disc 12 is provided with screen teeth 13. The screen teeth 13 on every two adjacent screen shafts 11 are staggered. In this embodiment, the sieve shaft 11 includes an active sieve shaft 11a and a driven sieve shaft 11b, which are alternately arranged. The end of the active sieve shaft 11a is connected to a first motor 14 through a first reducer 15. The active sieve shaft 11a and the driven sieve shaft 11b correspond one-to-one, and each active sieve shaft 11a is connected to the corresponding driven sieve shaft 11b through belt drive. During the screening process, the sieve shaft 11a provides power for the coke to move from the feed end 16 to the discharge end 17 by rotating.

[0020] In addition, the roller screen assembly 1 gradually tilts downward from the feed end 16 to the discharge end 17. In this embodiment, the slope is 15°, which further ensures that the coke moves smoothly from the feed end 16 to the discharge end 17.

[0021] The spacing between adjacent screen shafts 11 gradually decreases from the feed end 16 to the discharge end 17. In this embodiment, the shaft spacing gradually changes from 50mm to 30mm to achieve a step-by-step separation of coke water and powdered coke.

[0022] The number of screen discs 12 on each screen shaft 11 can be adjusted and pads of different thicknesses can be installed between adjacent screen discs 12 to adjust the spacing between screen discs 12 and meet different coke particle size requirements.

[0023] The crushing component 2 is disposed at the discharge end 17 of the roller screen assembly 1. The crushing component 2 includes a fixed roller 21 and a floating roller 25. The fixed roller 21 is flush with the discharge end 17 of the roller screen assembly 1, and the floating roller 25 is disposed above the fixed roller 21. The fixed roller 21 is provided with a plurality of first blades 22, and the floating roller 25 is provided with a plurality of second blades 26 that match the first blades 22.

[0024] One end of the fixed roller 21 is connected to the second motor 23 via the second reducer 24. The top of the integrated screening and crushing structure is equipped with a third motor 27 and a third reducer 28. The third motor 27 is connected to the third reducer 28, and the third reducer 28 is connected to the floating roller 25 via a belt.

[0025] After coke enters the upper side of the roller screen assembly 1 through the feed end 16, powdered coke and small pieces of coke fall directly into the lower collection bin through the screen gaps; large pieces of coke are pushed to the discharge end 17 by the screen teeth 13, and fall into the space between the opposing rotating fixed rollers 21 and floating rollers 25 for crushing. The crushed products fall into the unified conveying channel through the grate (aperture ≤50mm). The fixed rollers 21 provide basic extrusion pressure, and the floating rollers 25 can dynamically adjust their spacing through a hydraulic system to automatically adjust the crushing pressure according to the hardness of the coke, reducing energy consumption and avoiding overload.

[0026] This embodiment integrates roller screening and crushing functions, which can solve the problems of material blockage, overflow and processing efficiency in the closed decoking process of traditional equipment.

[0027] Example 2 The difference between this embodiment and Embodiment 1 is that the integrated sieve crusher structure also includes a sieve disc gap adjustment component 3, two baffles 4, and slide rods 5 corresponding one-to-one with the sieve shaft 11.

[0028] Both ends of the sieve shaft 11 are slidably inserted into the baffles 4, and the sieve discs 12 are all arranged between the two baffles 4. A screening channel is formed between the two baffles 4 to ensure that the coke moves above the sieve discs 12.

[0029] The slide bar 5 is located below the corresponding sieve shaft 11 and parallel to the sieve shaft 11. Multiple sliders 6 are slidably arranged on the slide bar 5. Each slider 6 corresponds to a sieve plate 12 above. The top of the slider 6 is rotatably connected to the corresponding sieve plate 12 through a bracket 61. In this embodiment, the top of each bracket 61 is provided with two limiting rings 62. The two limiting rings 62 are rotatably sleeved on both ends of the sieve plate 12.

[0030] The screen disc gap adjustment assembly 3 includes a slide 31, a push rod motor 32, two main beams 33, and several drive beams 34. The slide 31 is arranged parallel to the screen shaft 11. One end of each of the two main beams 33 is hinged, and the other end of each main beam 33 is slidably hinged to the slide 31. The two ends of the push rod motor 32 are respectively connected to the two main beams 33. Two baffles 4 are respectively hinged to the ends of the two main beams 33 away from each other. The drive beams 34 are all arranged perpendicular to the screen shaft 11, and one end of each drive beam 34 is evenly hinged to the two drive beams 34. The drive beams 34 are slidably inserted into the slider 6. The gap of the screen disc 12 can be evenly adjusted by adjusting the opening angle of the two main beams 33 by the push rod motor 32.

[0031] In this embodiment, by setting the screen plate gap adjustment component 3, the gap of the screen plate 12 can be adjusted according to the required coke particle size. There is no need to disassemble the screen plate 12 and the pad used for adjusting the gap, making the adjustment more convenient and without damaging the sealed environment of the sealed coke removal equipment.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
