Description

Technical Field

[0001] This invention relates to the technical field of calcined petroleum coke processing equipment, specifically to an integrated equipment for efficient crushing and grading of calcined petroleum coke. Background Technology

[0002] As a key industrial raw material, the uniformity of the crushed particle size of calcined petroleum coke directly determines the quality of subsequent processing. Therefore, the coordinated operation of multi-stage crushing and precision screening is of paramount importance.

[0003] Currently available petroleum coke crushing equipment generally suffers from low integration and poor functional connection: most equipment lacks a dedicated screening transition connection structure, and the primary and secondary crushing boxes are often directly transferred or require additional conveying equipment for connection, resulting in a fragmented crushing process. Simultaneously, the lack of an efficient built-in screening mechanism adapted to the crushing box prevents the real-time screening of incompletely crushed large pieces of petroleum coke during the crushing process and their guidance to secondary crushing. This leads to either large pieces of material being directly mixed into the finished product, resulting in unqualified particle sizes, or requiring the entire crushed material to be transferred to an independent screening device for sorting, and then the unqualified material to be returned to the crushing equipment. This not only increases equipment investment, floor space, and material transfer costs, but also poses risks of material loss and blockage during transfer, severely impacting crushing efficiency and continuity. Furthermore, the material collection structure design between the secondary crushed material and the primary screened qualified material is unreasonable, easily leading to material accumulation and poor flow guidance, further reducing the functionality and practicality of the equipment. Therefore, there is an urgent need to develop an integrated device that connects the two crushing boxes through a dedicated screening transition component, has a built-in screening mechanism for precise sorting and guiding of materials to secondary crushing, and can achieve efficient convergence of qualified materials, in order to solve the above-mentioned technical bottlenecks. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides an integrated high-efficiency crushing and grading device for calcined petroleum coke. It features a primary crushing chamber and a secondary crushing chamber, with a screening transition component between them. This transition component guides the material while simultaneously screening large petroleum coke particles. The secondary crushing chamber then performs secondary crushing of the large petroleum coke particles. The crushed petroleum coke is then fed into a feed pipe. This device is highly functional and effective, solving the problems of current equipment's inability to effectively crush petroleum coke, its large footprint, and its unsatisfactory performance.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention specifically adopts the following technical solution:

[0008] An integrated high-efficiency crushing and grading device for calcined petroleum coke includes a base, a material guiding mechanism, a primary crushing box, a screening transition assembly, a secondary crushing box, and a guide pipe. The base has a support frame fixedly connected to one side, and the material guiding mechanism is fixedly connected to the support frame. The material guiding mechanism includes a material guiding pipe fixedly connected to one side of the support frame and a flared section formed at the upper part of the material guiding pipe. The screening transition assembly includes an inclined transition pipe and a screening plate slidably connected to the bottom cavity of the transition pipe. The flared section is fixedly connected to the lower surface of the transition pipe, and small petroleum coke particles enter the flared section through holes in the screening plate, achieving preliminary screening and collection of the petroleum coke particles. The primary crushing box is fixedly connected to the top of the transition pipe for preliminary crushing of the petroleum coke. The secondary crushing box is fixedly connected to the bottom of the transition pipe for secondary crushing of the screened petroleum coke. The guide pipe connects the bottom of the secondary crushing box and the material guiding pipe.

[0009] Furthermore, T-shaped protrusions are fixedly connected to both sides of the screening plate, and the T-shaped protrusions are slidably connected to the corresponding T-shaped grooves opened in the transition pipe.

[0010] Furthermore, a first motor is mounted on a mounting plate fixed to one side of the transition pipe, and a turntable is coaxially fixedly connected to the lower end of the output shaft of the first motor. A protrusion is fixedly connected to one side of the screening plate, and a connecting rod is rotatably connected between the turntable and the protrusion.

[0011] Furthermore, the bottom of the flared section forms an inclined plate that extends to the feed tube.

[0013] Furthermore, a storage cylinder is provided on the upper surface of the base below the guide tube.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, the present invention provides an integrated equipment for high-efficiency crushing and grading of calcined petroleum coke, which has the following beneficial effects:

[0016] This invention integrates material guiding, screening, two-stage crushing, and material collection functions into one unit by precisely connecting the primary and secondary crushing chambers through a screening transition component. This eliminates the need for additional material transfer equipment and independent screening equipment, significantly reducing the equipment's footprint and investment costs. Simultaneously, the direct connection of various functional components via transition pipes and guide pipes avoids the losses and blockages encountered during material transfer in traditional equipment, significantly improving overall operational continuity. The screening transition component features a built-in sliding screening plate, which, in conjunction with a first motor, turntable, and connecting rod forming a linkage drive structure, enables dynamic reciprocating screening. This quickly separates qualified materials after initial crushing from incompletely crushed large pieces, effectively preventing screen hole blockage and improving screening efficiency. Unqualified large pieces are directly introduced into the secondary crushing chamber for secondary crushing via an inclined transition pipe, ensuring uniform final output particle size and solving the problems of incomplete crushing and unqualified particle size in traditional equipment.

Detailed Implementation

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example

[0028] like Figures 1-8 As shown in one embodiment of the present invention, an integrated high-efficiency crushing and grading device for calcined petroleum coke includes a base 1, a material guiding mechanism 3, a primary crushing box 4, a screening transition assembly 5, a secondary crushing box 6, and a guide pipe 7. A support frame 2 is fixedly connected to one side of the base 1, and the material guiding mechanism 3 is fixedly connected to the support frame 2. The material guiding mechanism 3 includes a material guiding pipe 301 fixedly connected to one side of the support frame 2, and a flared section 302 formed on the upper part of the material guiding pipe 301. The screening transition assembly 5 includes an inclined transition pipe 501 and a sliding connection... A screening plate 502 at the bottom cavity of the transition pipe 501, with a flared section 302 fixedly connected to the lower surface of the transition pipe 501, allows small pieces of petroleum coke particles to enter the flared section 302 through holes in the screening plate 502, thus collecting the petroleum coke particles after preliminary screening. A primary crushing box 4 is fixedly connected to the top of the transition pipe 501 to achieve preliminary crushing of the petroleum coke. A secondary crushing box 6 is fixedly connected to the bottom of the transition pipe 501 to achieve secondary crushing of the screened petroleum coke. A guide pipe 7 connects the bottom of the secondary crushing box 6 to the guide pipe 301.

[0029] It should be noted that the base 1 provides stable support for the entire equipment, ensuring the stability of subsequent structural operations; the support frame 2 is used to fix and install the material guiding mechanism 3, providing a reliable mounting carrier for the material guiding mechanism 3. The petroleum coke raw material first enters the primary crushing box 4 for preliminary crushing. The crushed material enters the inclined transition pipe 501, and the inclined structure of the transition pipe 501 can guide the flow of material by gravity. The screening plate 502 in the bottom cavity of the transition pipe 501 screens the material after preliminary crushing. Small petroleum coke particles that meet the particle size requirements fall through the holes on the screening plate 502 into the lower fixedly connected flared section 302. Then the material enters the guide pipe 301 through the flared section 302; the large petroleum coke particles that do not pass the screening flow along the inclined transition pipe 501 to the secondary crushing box 6 at the bottom for secondary crushing. The material after secondary crushing flows into the guide pipe 301 through the guide pipe 7, and finally outputs to the storage cylinder 8 below for collection through the guide pipe 301. The entire device has a high degree of integration, occupies little space, and is convenient for practical use.

[0030] like Figure 6 As shown, in some embodiments, T-shaped protrusions 503 are fixedly connected to both sides of the screening plate 502, and the T-shaped protrusions 503 are slidably connected to the corresponding T-shaped grooves opened in the transition pipe 501.

[0031] It should be noted that the T-shaped protrusion 503 is slidably connected in the T-shaped groove, which can prevent the screening plate 502 from shifting or falling off during the sliding process, and plays a limiting role, ensuring that the screening plate 502 always moves within the preset trajectory of the bottom cavity of the transition pipe 501, thus ensuring the stability and continuity of the screening operation.

[0032] like Figure 7 and Figure 8 As shown, in some embodiments, a first motor 505 is mounted on a mounting plate 504 fixed on one side of the transition pipe 501, and a turntable 506 is coaxially fixedly connected to the lower end of the output shaft of the first motor 505. A protrusion 508 is fixedly connected to one side of the screening plate 502, and a connecting rod 507 is rotatably connected between one side of the turntable 506 and the protrusion 508.

[0033] It should be noted that the mounting plate 504 on one side of the transition pipe 501 provides a fixed mounting base for the first motor 505, ensuring the stability of the first motor 505 during operation. When the first motor 505 starts, its output shaft drives the coaxially fixed turntable 506 to rotate. The turntable 506 is linked with the protrusion 508 on one side of the screening plate 502 through the connecting rod 507, converting the rotational motion of the turntable 506 into the reciprocating linear motion of the screening plate 502. The reciprocating motion of the screening plate 502 can prevent material from accumulating on the surface of the screening plate 502, prevent clogging of the screening holes, and at the same time increase the contact frequency between the material and the screening plate 502, speeding up the screening speed and improving the screening efficiency.

[0034] like Figure 2 As shown, in some embodiments, an inclined plate 303 is formed at the bottom of the flared section 302, and the inclined plate 303 extends to the guide tube 301.

[0035] It should be noted that the inclined structure of the inclined plate 303 can use gravity to allow small pieces of petroleum coke particles falling into the flared section 302 to automatically slide along the surface of the inclined plate 303 into the feed pipe 301, thus avoiding material accumulation at the bottom of the flared section 302 and ensuring smooth material flow.

[0036] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, both the primary crushing box 4 and the secondary crushing box 6 include a box body 9, wherein: the box body 9 in the primary crushing box 4 is fixedly connected to the top of the transition pipe 501, and the top of the box body 9 is connected to a feed funnel 10; the box body 9 in the secondary crushing box 6 is connected between the bottom of the transition pipe 501 and the top of the guide pipe 7, and two symmetrically distributed guide plates 11 are fixedly connected to the upper inner side of the box body 9; two symmetrically distributed crushing rollers 12 are rotatably connected to the inner side of the box body 9, and crushing hammers 13 are fixedly connected to each of the two crushing rollers 12; a second motor 14 is installed on one side of the box body 9, and the second motor 14 is coaxially connected and fixed to one of the crushing rollers 12; the ends of the two crushing rollers 12 extend to the outside of the box body 9 and are fixedly connected to gears 16, and the two gears 16 mesh with each other; a fixing seat 15 is fixedly connected to both the box body 9 and the transition pipe 501, and adjacent fixing seats 15 are fixedly connected by bolts.

[0037] It should be noted that in the primary crushing box 4, its box body 9 is fixed to the top of the transition pipe 501. The feed funnel 10 at the top is used to introduce the petroleum coke raw material to be crushed. The two crushing rollers 12 inside the box body 9 are the core crushing components. The crushing hammers 13 on the crushing rollers 12 can enhance the crushing force. When the second motor 14 is started, it drives one of the crushing rollers 12 connected to it to rotate. The gear 16 at the end of the crushing roller 12 meshes with the gear 16 at the end of the other crushing roller 12, thereby driving the other crushing roller 12 to rotate synchronously in the opposite direction. The two crushing rollers 12 rotate in opposite directions. The petroleum coke raw material falling into the primary crushing chamber is squeezed and impacted to achieve initial crushing. In the secondary crushing chamber 6, the chamber body 9 connects the bottom of the transition pipe 501 and the top of the guide pipe 7. Two symmetrical guide plates 11 on the upper inner side can guide large petroleum coke particles flowing in from the transition pipe 501 to fall precisely between the two crushing rollers 12, preventing the material from deviating from the crushing area and improving crushing efficiency. The operating principle of the crushing rollers 12, crushing hammers 13, second motor 14, and gears 16 is the same as that of the primary crushing chamber 4, realizing secondary crushing of large materials and ensuring that the particle size of the material meets the requirements. In addition, the fixing seat 15 on the chamber body 9 and the transition pipe 501 is fixed by bolts, which can realize the firm connection between the primary crushing chamber 4, the secondary crushing chamber 6 and the screening transition assembly 5, ensuring the connection stability of each component during equipment operation, and facilitating the disassembly, installation and maintenance of the equipment.

[0038] like Figure 1 As shown, in some embodiments, a storage cylinder 8 is provided on the upper surface of the base 1 below the guide tube 301.

[0039] It should be noted that the storage cylinder 8 is used to collect the crushed petroleum coke particles, which facilitates the centralized collection of petroleum coke particles.

[0040] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention 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.
