Description

Technical Field

[0001] This utility model relates to the technical field of petroleum coke storage equipment, and in particular to a petroleum coke raw material silo. Background Technology

[0002] In the field of petroleum coke processing and storage, petroleum coke feedstock silos are key facilities for achieving temporary storage and stable supply of feedstock. Petroleum coke is characterized by high hardness, uneven particle size, and a tendency to absorb moisture and clump, leading to two major technical challenges in the discharge process of existing feedstock silos.

[0003] Firstly, petroleum coke easily accumulates and adheres to the pipe walls inside the discharge pipe, causing blockages and severely impacting discharge efficiency. This often necessitates frequent shutdowns for manual unblocking, increasing labor intensity and reducing production continuity. Secondly, traditional raw material silos generate significant dust during discharge due to material flow, polluting the work environment, harming operator health, and causing dust to adhere to equipment surfaces, accelerating wear on mechanical parts and failing to meet environmental protection requirements. Furthermore, existing dust collection devices are mostly independent configurations requiring additional power, resulting in high energy consumption and low equipment integration. Therefore, there is an urgent need to design a new petroleum coke raw material silo. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a petroleum coke feedstock bin, which solves the problem that petroleum coke easily accumulates and adheres to the pipe wall in the discharge pipe, forming blockages that seriously affect discharge efficiency and even require frequent shutdowns for manual unblocking, which not only increases labor intensity but also reduces production continuity.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a petroleum coke raw material silo, comprising a silo body, a discharge pipe installed on the silo body, a protective cover installed on the discharge pipe, a drive motor installed on the protective cover, a rack installed above the protective cover, a sliding rod installed on the rack through an opening, a fixed rod slidably sleeved on the sliding rod and fixedly connected to the protective cover via an elastic mechanism, an impact block fixedly installed on the rack, the rack connected to the drive motor via a rotation mechanism, a dust collection box installed on the protective cover, an annular filter screen installed on the dust collection box, a transmission chamber provided inside the shell of the dust collection box, a transmission shaft rotatably installed inside the transmission chamber extending to the top of the protective cover, the transmission shaft connected to the drive motor via a transmission mechanism, a fan assembly provided inside the dust collection box, the fan shaft of the fan assembly extending into the transmission chamber and connected to the transmission shaft via a synchronization mechanism.

[0008] Preferably, the elastic mechanism includes a spring sleeved on the outside of the slide bar, with both ends of the spring connected to the inner wall of the opening and the outer wall of the fixed rod, respectively.

[0009] Preferably, the rotating mechanism includes a first gear fixedly mounted on the output shaft of the drive motor, the first gear meshing with a rack.

[0013] (III) Beneficial Effects

[0014] The beneficial effects of this utility model are:

[0015] 1. Through the coordinated action of the drive motor, incomplete gears and springs, the impact block periodically impacts the discharge pipe, effectively shaking off the petroleum coke clumps attached to the pipe wall, avoiding manual unblocking and improving discharge efficiency.

[0016] 2. By using a drive motor to simultaneously drive the impact device and the dust collection system, a single power source achieves dual functions, reducing energy consumption compared to traditional independent dust removal equipment.

[0017] 3. The gear transmission system has a reasonable layout and high transmission efficiency, ensuring that the impact and suction actions operate synchronously and stably.

[0018] 4. The sealed design of the protective cover and dust collection box prevents dust from spilling out, improving the overall sealing performance and reliability of the equipment. Attached Figure Description

[0025] Reference Figure 1-4 A petroleum coke raw material silo includes a silo body 1, which is made of high-strength steel structure or reinforced concrete and has good load-bearing capacity and sealing properties, and is used to store petroleum coke raw materials.

[0026] The bottom of the silo 1 is inclined and equipped with a discharge pipe 2. The diameter of the discharge pipe 2 is designed according to the actual discharge requirements to facilitate the smooth flow of petroleum coke. A protective cover 3 made of stainless steel is installed on the discharge pipe 2 to prevent dust from overflowing during the petroleum coke discharge process and to protect the internal components.

[0027] The protective cover 3 is equipped with a drive motor 10, which is a variable frequency motor and can adjust the speed according to actual needs to control the working frequency of subsequent components.

[0028] A rack 4 is provided above the protective cover 3. A slide rod 7 is provided on the rack 4 through an opening 6. A fixing rod 8, which is fixedly connected to the protective cover 3, is slidably sleeved on the slide rod 7 through an elastic mechanism. An impact block 5 is fixedly provided on the rack 4. The impact block 5 is made of high-hardness alloy material and has good impact resistance.

[0029] The rack 4 is connected to the drive motor 10 via a rotating mechanism. The elastic mechanism includes a spring 9 sleeved on the outside of the slide rod 7. The two ends of the spring 9 are connected to the inner wall of the opening 6 and the outer wall of the fixed rod 8, respectively. The spring 9 is made of high-strength spring steel, and its elastic coefficient has been precisely calculated to ensure that the rack 4 receives sufficient impact force while avoiding excessive impact force that could damage the equipment.

[0030] The rotating mechanism includes a first gear 12 fixedly mounted on the output shaft of the drive motor 10. The first gear 12 meshes with the rack 4. The first gear 12 is an incomplete gear. By reasonably designing its number of teeth and distribution, the rack 4 can achieve reciprocating motion.

[0031] A dust collection box 15 is installed on the protective cover 3. The dust collection box 15 is a box structure. An annular filter 16 is installed on the dust collection box 15. The annular filter 16 is made of woven metal fiber and has high filtration accuracy and air permeability.

[0032] The dust collection box 15 has a transmission chamber 18 inside its housing. A transmission shaft 13 extending above the protective cover 3 is rotatably mounted inside the transmission chamber 18. The transmission shaft 13 is connected to the drive motor 10 through a transmission mechanism.

[0033] The transmission mechanism includes a second gear 11 fixedly mounted on the output shaft of the drive motor 10, and a third gear 14 fixedly mounted on the transmission shaft 13 that meshes with the second gear 11. The size ratio of the second gear 11 to the third gear 14 is 5:1. By setting such a gear transmission ratio, the rotational speed of the transmission shaft 13 can be amplified to meet the working requirements of the fan assembly 17.

[0034] The dust collection box 15 houses a fan assembly 17, which employs an axial flow fan, characterized by high airflow and low noise. The fan shaft of the fan assembly 17 extends into the transmission chamber 18 and is connected to the transmission shaft 13 via a synchronization mechanism. The synchronization mechanism includes a fourth gear 19 fixedly mounted on the transmission shaft 13, and a fifth gear 20 fixedly mounted on the fan shaft of the fan assembly 17, meshing with the fourth gear 19. This gear meshing ensures stable power transmission and stable operation of the fan assembly 17.

[0035] It should be noted that both the fourth gear 19 and the fifth gear 20 are bevel gears, and they mesh perpendicularly.

[0036] Components not specifically described in this utility model are all standard parts and can be purchased from the market. The specific connection methods for each component all employ mature methods from the prior art, and will not be detailed here. Content not described in detail in this specification belongs to prior art known to those skilled in the art.

[0037] In practical use, the working principle of this utility model is as follows:

[0038] After the drive motor 10 starts, the first gear 12 (incomplete gear) on its output shaft meshes with the rack 4, driving the rack 4 to move away from the discharge pipe 2. During this process, the slide rod 7 slides on the fixed rod 8 and stretches the spring 9. When the first gear 12 disengages from the rack 4, the spring 9 returns to its original position, pushing the rack 4 to move quickly towards the discharge pipe 2, causing the impact block 5 on the rack 4 to impact the discharge pipe 2, thereby shaking off the petroleum coke adhering to the inner wall of the discharge pipe 2 or blocking the pipe opening, ensuring smooth discharge.

[0039] Simultaneously, the second gear 11 on the output shaft of the drive motor 10 meshes with the third gear 14 on the transmission shaft 13. Since the size ratio of the second gear 11 to the third gear 14 is 5:1, the transmission shaft 13 rotates at a high speed. The fourth gear 19 on the transmission shaft 13 meshes with the fifth gear 20 on the fan shaft of the fan assembly 17, transmitting power to the fan assembly 17, causing it to rotate at high speed and generate suction. Under the action of the fan assembly 17, the air and dust inside the protective cover 3 are filtered through the annular filter 16 (intercepting large particles) and then sucked into the dust collection box 15. The dust collection box 15 can be connected to a cloth bag for further collection; air can be discharged, and the cloth bag can collect dust.

[0040] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
