Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of unloading equipment for petroleum coke storage, specifically an unloading mechanism for petroleum coke storage. Background Technology
[0002] Petroleum coke storage discharge refers to the process of transferring petroleum coke stored in silos to subsequent processing or transportation stages via a specific mechanism. Because the raw petroleum coke has a high moisture content before calcination, it is prone to clumping during storage. Furthermore, the silo outlet is typically small, making it difficult for the petroleum coke to detach from the bottom of the silo, easily leading to blockages and affecting normal discharge.
[0003] According to announcement number CN219688130U, a material feeding mechanism for petroleum coke storage is disclosed, mainly relating to the field of petroleum coke storage material feeding equipment. It includes a material feeding mechanism located at the discharge end of the silo, and the material feeding mechanism is either a vibrating material feeding mechanism or a negative pressure material feeding mechanism; the vibrating material feeding mechanism or the negative pressure material feeding mechanism feeds the petroleum coke at the discharge end of the silo.
[0004] This petroleum coke storage unloading mechanism, while assisting in the unloading operation of petroleum coke stored in the silo and preventing blockage at the bottom of the silo due to clumps of petroleum coke, often suffers from problems such as material clumping and adhesion, leading to poor unloading and severely affecting storage efficiency. In addition, it lacks a stirring structure, making it prone to jamming due to material interference, which greatly restricts the effectiveness of the coordinated operation of unloading and stirring. Utility Model Content
[0005] The purpose of this utility model is to provide a material feeding mechanism for petroleum coke storage, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a material discharge mechanism for petroleum coke storage, comprising a silo, wherein a material discharge mechanism is fixedly connected to the top of the silo, and a switching mechanism is fixedly connected to the bottom of the silo;
[0007] The material feeding mechanism includes a support ring, which is fixedly connected to the surface of the hopper. An electric gear is fixedly connected to the bottom left end of the support ring. A toothed ring is meshed with the surface of the electric gear. A vertical ring is fixedly connected to the top of the toothed ring. A top ring is fixedly connected inside the vertical ring. A column is fixedly connected inside the top ring. A spring is fixedly connected inside the column. A T-shaped rod is fixedly connected to the bottom end of the spring. A ring frame is fixedly connected to the bottom end of the T-shaped rod. An agitator is fixedly connected to the bottom end of the ring frame. A rotating ring is fixedly connected to the surface of the T-shaped rod. An inner ring is fixedly connected between the bottom of the rotating ring and the top of the ring frame.
[0008] Preferably, a through hole is formed inside the left end of the support ring, and the surface of the electric gear passes through the through hole formed inside the left end of the support ring, so that the electric gear can work under the support of the support ring.
[0009] Preferably, a limiting groove is formed inside the column, and the surface of the T-shaped rod is slidably connected to the inside of the limiting groove.
[0010] Preferably, a through hole is provided at the bottom end of the column, and the surface of the T-shaped rod passes through the through hole at the bottom end of the column, which facilitates the movement of the T-shaped rod in the through hole. The elastic force of the spring can prevent the agitator from getting stuck due to the presence of some petroleum coke at the contact point between the agitator and the inside of the hopper, thereby improving the material discharge and agitation efficiency.
[0011] Preferably, a conical annular cavity is formed inside the hopper, and the surface of the agitator matches the inside of the conical annular cavity. During the rotation of the agitator, it stirs the petroleum coke in the hopper, breaking up any lumps or sticky materials, thus creating conditions for smooth material discharge. In addition, the springs connecting the relevant components of the agitator play an important role. Their elastic force can buffer the jamming caused by localized petroleum coke accumulation when the agitator contacts the inside of the hopper, preventing the agitator from getting stuck due to such jamming, thereby significantly improving the material discharge and stirring efficiency.
[0012] Preferably, the switching mechanism includes a base block, which is fixedly connected to the bottom of the hopper, and a stopper is provided at the bottom of the base block, with bolts threaded onto the surface of the stopper.
[0013] Preferably, the bottom of the base block has a slot, and the upper surface of the stopper block matches the inside of the slot. After mixing is completed, the bolts can be removed from the stopper block and the base block, so that the stopper block can be easily removed and the corresponding material falling operation can be performed, thereby realizing the control of material falling.
[0014] Preferably, the bottom block has a threaded hole on its surface, and the bolt surface is threaded into the threaded hole, which facilitates the fixing of the plug block with the bolt. During the stirring stage of petroleum coke, in order to prevent the material from falling from the bottom of the silo before the stirring is completed, a plug block is used to block the bottom block. The bottom block is located at the bottom outlet of the silo, and the plug block and the bottom block fit tightly together. Through reasonable structural design, the material can be effectively prevented from falling, ensuring that the stirring process is carried out in a relatively closed space, so that the agitator can fully and evenly stir the material, ensuring the stirring effect. In addition, the plug block can be easily removed from the bottom block by simply removing the bolt connecting the plug block and the bottom block. With the removal of the plug block, the bottom outlet of the silo is unobstructed, and the stirred petroleum coke material in the silo can fall smoothly, achieving precise material drop control and meeting the material conveying needs of subsequent production processes.
[0015] Compared with the prior art, this utility model provides a material feeding mechanism for petroleum coke storage, which has the following beneficial effects:
[0016] 1. The material feeding mechanism for petroleum coke storage uses an electric gear to rotate a gear ring, which in turn rotates the vertical ring and top ring. This, in turn, causes the column, T-shaped rod, and rotating ring to rotate, which in turn causes the agitator to rotate inside the silo, thus performing material mixing operations. During the mixing process, the material is crushed, facilitating feeding. Furthermore, the elastic force of the springs prevents the agitator from jamming due to the presence of petroleum coke at the contact point with the silo interior, thereby improving the feeding and mixing efficiency of the material.
[0017] 2. The material discharge mechanism for this petroleum coke storage unit, through its set switching mechanism, allows for easy removal of the stopper block and material discharge operation after mixing is completed, simply by removing the bolts from the stopper block and bottom block. This enables control over material discharge. The aforementioned reasonable structural design effectively prevents material from falling, ensuring the mixing process takes place in a relatively enclosed space. This allows the agitator to fully and evenly mix the material, guaranteeing the mixing effect. Furthermore, simply removing the bolts connecting the stopper block and bottom block allows for easy removal of the stopper block from the bottom block, leaving the bottom outlet of the silo unobstructed.

[0027] This utility model provides the following technical solution:
[0028] Example 1
[0029] Combination Figures 2 to 5 A material feeding mechanism for petroleum coke storage includes a silo 1, a material feeding mechanism 2 fixedly connected to the top of the silo 1, and a switching mechanism 3 fixedly connected to the bottom of the silo 1.
[0030] The feeding mechanism 2 includes a support ring 21, which is fixedly connected to the surface of the hopper 1. An electric gear 22 is fixedly connected to the bottom left end of the support ring 21. A toothed ring 23 is meshed with the surface of the electric gear 22. A vertical ring 24 is fixedly connected to the top of the toothed ring 23. A top ring 241 is fixedly connected inside the vertical ring 24. A column 25 is fixedly connected inside the top ring 241. A spring 251 is fixedly connected inside the column 25. A T-shaped rod 26 is fixedly connected to the bottom end of the spring 251. A ring frame 28 is fixedly connected to the bottom end of the T-shaped rod 26. An agitator 29 is fixedly connected to the bottom end of the ring frame 28. A rotating ring 27 is fixedly connected to the surface of the T-shaped rod 26. An inner ring 261 is fixedly connected between the bottom of the rotating ring 27 and the top of the ring frame 28. A through hole is opened inside the left end of the support ring 21. The surface of the electric gear 22 passes through the through hole opened inside the left end of the support ring 21. A limiting slot is opened inside the column 25. The surface of the T-shaped rod 26 is slidably connected to the inside of the limiting slot.
[0031] Furthermore, a through hole is opened at the bottom of the column 25, and the surface of the T-shaped rod 26 passes through the through hole opened at the bottom of the column 25. A conical annular cavity is opened inside the hopper 1. The surface of the agitator 29 matches the inside of the conical annular cavity. The electric gear 22 drives the gear ring 23 to rotate and drives the vertical ring 24 and the top ring 241 to rotate, thereby driving the column 25, the T-shaped rod 26 and the rotating ring 27 to rotate, and correspondingly driving the agitator 29 to rotate inside the hopper 1, thereby performing the corresponding material mixing operation. During the mixing process, corresponding crushing is carried out, which facilitates material discharge. Moreover, the elastic force of the spring 251 can avoid the phenomenon of the agitator 29 getting stuck due to the presence of some petroleum coke at the contact point between the agitator 29 and the inside of the hopper 1, thereby improving the material discharge and mixing efficiency.
[0032] Example 2
[0033] See Figure 1-5 Furthermore, based on Embodiment 1, the switching mechanism 3 includes a bottom block 31, which is fixedly connected to the bottom of the hopper 1. A stopper 32 is provided at the bottom of the bottom block 31, and a bolt 33 is threadedly connected to the surface of the stopper 32. A bayonet is opened at the bottom of the bottom block 31, and the upper surface of the stopper 32 matches the inside of the bayonet.
[0034] Furthermore, a threaded hole is provided on the surface of the bottom block 31, and the surface of the bolt 33 is threadedly connected to the inside of the threaded hole. After the mixing is completed, the bolt 33 can be removed from the plug block 32 and the bottom block 31, so that the plug block 32 can be easily removed and the corresponding material falling operation can be carried out, thereby realizing the control of material falling.
[0035] In actual operation, when this device is used, during the petroleum coke feeding operation, the material is fed from the top of the hopper 1. Then, during feeding, in order to control the feeding and facilitate the falling, the electric gear 22 drives the gear ring 23 to rotate, which in turn drives the vertical ring 24 and the top ring 241 to rotate, thereby driving the column 25, T-shaped rod 26 and rotating ring 27 to rotate, and correspondingly driving the agitator 29 to rotate inside the hopper 1, thereby performing the corresponding material mixing operation. The elastic force of the spring 251 can prevent the agitator 29 from getting stuck due to the presence of some petroleum coke at the contact point with the inside of the hopper 1, thereby improving the feeding and mixing efficiency of the material.
[0036] During mixing, to prevent material from falling, the bottom block 31 needs to be blocked by the stopper 32. After mixing is completed, the bolt 33 can be removed from the stopper 32 and the bottom block 31, so that the stopper 32 can be easily removed and the corresponding material falling operation can be carried out, thereby realizing the control of material falling.
