Description

Technical Field

[0001] This invention relates to the field of calcined petroleum coke processing technology, specifically to an automated unloading buffer device for calcined petroleum coke. Background Technology

[0002] Calcined petroleum coke is a key carbon material obtained by calcining petroleum coke at high temperatures. Known as "industrial salt," it is an indispensable raw material for modern basic industries. The core value of calcined petroleum coke is reflected in two pillar industries: first, it is the "heart" of the electrolytic aluminum industry, used to manufacture the carbon anodes required for aluminum electrolytic cells; second, it is a key material in electric arc furnace steelmaking, serving as a graphite electrode to utilize the high temperatures generated by the electric arc to melt steel. Furthermore, it is also used as a carbon raiser in steel smelting and is widely used in the manufacture of carbon brushes, battery anodes, and refractory materials.

[0003] In the automated unloading and conveying system for calcined petroleum coke processing, when the material falls vertically from the discharge port onto the conveyor belt below, the resulting concentrated material flow will cause severe impact and slapping on the belt surface. This continuous impact will not only directly wear down the cover rubber layer of the conveyor belt, but also cause fatigue damage to the skeleton material inside the conveyor belt, thus significantly shortening its service life. Therefore, we propose an automated unloading buffer device for calcined petroleum coke to solve the above problems. Summary of the Invention

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides an automated unloading buffer device for calcined petroleum coke, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention specifically adopts the following technical solution: An automated unloading buffer device for calcined petroleum coke includes a buffer hopper, a feeding buffer assembly installed inside the buffer hopper, and a dust removal assembly installed outside the buffer hopper. The feeding buffer assembly includes a support plate fixed inside the buffer hopper. Two buffer seats are fixed to the top of the support plate. Two buffer plates are slidably connected to the upper limit of the buffer seats. A receiving plate is fixed to the top of the two buffer plates. Damping buffers are fixed at equal intervals inside the buffer seats. The top of the damping buffers is fixedly connected to the corresponding buffer plates.

[0006] Furthermore, the dust removal assembly includes two dust collection hoods that are connected and fixed to the outer wall of the buffer hopper, and U-shaped pipes that are connected and fixed to the two dust collection hoods. A filter box is fixed to the back of the buffer hopper by two supports. The inlet pipe of the filter box is connected and fixed to the U-shaped pipe. A filter frame is fixed inside the filter box, and a filter screen is fixed inside the filter frame.

[0007] Furthermore, a mounting base is fixed to the top of the filter frame, and a vibration motor for cleaning the filter screen is fixed to the top of the mounting base.

[0008] Furthermore, two extrusion plates are slidably connected inside the filter box. Two guide rods are fixed to one side wall of each extrusion plate. The other end of each guide rod slides through the filter box and extends to its outside. A moving plate is fixed to one end of each of the two guide rods. A drive mechanism for driving the two moving plates to move synchronously in opposite directions is installed at the bottom of the filter box.

[0009] Furthermore, the driving mechanism includes a drive shaft rotatably connected to the bottom of the filter box via bearings, a transmission rod fixed to the surface of the drive shaft, and connecting rods rotatably connected to both ends of the transmission rod via bearings. The other end of the connecting rod is rotatably connected to a corresponding moving plate via bearings.

[0010] Furthermore, two annular plates fixed inside the buffer hopper are provided between the two dust collection hoods, and a mesh cylinder is fixed between the two annular plates.

[0011] Furthermore, two wear-resistant plates are fixed inside the buffer hopper, and a second wear-resistant plate with a shape adapted to the top of the buffer plate is fixed thereon.

[0012] Compared with the prior art, the present invention provides an automated unloading buffer device for calcined petroleum coke, which has the following beneficial effects: This invention utilizes a feeding buffer assembly inside the buffer hopper, which actively absorbs the enormous impact kinetic energy generated when calcined petroleum coke falls, transforming the destructive impact force into a stable buffering force. This allows the calcined petroleum coke material to slide onto the conveyor belt at a slow and controllable speed, thereby extending the service life of the conveyor belt. Furthermore, the dust collection assembly collects and treats the dust generated as the calcined petroleum coke flows through the buffer hopper, minimizing dust generation when it falls onto the conveyor belt. Additionally, the dust collection assembly's filter box is symmetrically equipped with two extrusion plates, which compress the dust collected inside the filter box into blocks, thus minimizing dust generation during dust removal.

Detailed Implementation

[0015] 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. Example

[0016] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown in one embodiment of the present invention, an automated unloading buffer device for calcined petroleum coke includes a buffer hopper 1. A feeding buffer assembly 2 is installed inside the buffer hopper 1, and a dust removal assembly 3 is installed outside the buffer hopper 1. The dust removal assembly 3 includes two dust collection hoods 31 connected and fixed to the outer wall of the buffer hopper 1. U-shaped tubes 32 are connected and fixed to the two dust collection hoods 31. A filter box 33 is fixed to the back of the buffer hopper 1 by two supports. A door is hinged and sealed to one side wall of the filter box 33, facilitating the subsequent collection of... Dust is cleaned. The inlet pipe of the filter box 33 is connected and fixed to the U-shaped pipe 32. A filter frame 35 is fixed inside the filter box 33. A filter screen 36 is fixed inside the filter frame 35. A mounting base 37 is fixed on the top of the filter frame 35. A vibration motor 38 for cleaning the filter screen 36 is fixed on the top of the mounting base 37. After the vibration motor 38 is started, it can transmit vibration to the filter frame 35 through the mounting base 37, thereby cleaning the dust particles adsorbed on the lower surface of the filter screen 36 and maintaining its filtration permeability. The feeding buffer assembly 2 includes a support plate 21 fixed inside the buffer hopper 1. Two buffer seats 22 are fixed on the top of the support plate 21. Two buffer plates 23 are slidably connected to the upper limit of the buffer seats 22. A receiving plate 24 is fixed on the top of the two buffer plates 23. Damping buffers 25 are fixed at equal intervals inside the buffer seats 22. The top of the damping buffers 25 are fixedly connected to the corresponding buffer plates 23 respectively. The working principle and usage process of this invention: After installing this device on the conveyor belt equipment, the unloading pipe is then inserted into the top port of the buffer hopper 1 for connection. The calcined petroleum coke material entering the buffer hopper 1 from above will fall directly onto the receiving plate 24 of the feeding buffer assembly 2. At this time, the calcined petroleum coke material will impact the receiving plate 24. The receiving plate 24 will then drive the two fixed buffer plates 23 at the bottom to slide downwards along the limiting structure of the buffer seat 22. Simultaneously, the damping buffer 25 inside the buffer seat 22 will be compressed. When the damping buffer 25 is compressed, it can absorb the kinetic energy generated by the material impact through its own damping characteristics. Subsequently, the calcined petroleum coke material will slide onto the bottom inner wall of the buffer hopper 1, and then slide onto the conveyor belt for transport. This avoids damage to the conveyor belt caused by direct impact of calcined petroleum coke. During the unloading and buffering process, dust generated by the calcined petroleum coke will form a dust-laden airflow inside the buffer hopper 1. After connecting and fixing the outlet pipe of the filter box 33 to the inlet pipe of the negative pressure adsorption device, the dust-laden airflow in the buffer hopper 1 can be collected by the negative pressure adsorption. The dust-laden airflow will be transported to the interior of the filter box 33 through the dust collection hood 31 and the U-shaped pipe 32. Then, the dust-laden airflow can be filtered through the filter screen 36 of the filter box 33. When the dust-laden airflow passes through the filter screen 36, the dust particles are intercepted on the lower surface of the filter screen 36, and the purified gas is discharged from the outlet of the filter box 33. Therefore, the dust generated by the calcined petroleum coke falling onto the conveyor belt can be suppressed to the greatest extent.

[0017] like Figure 4As shown, in some embodiments, two extrusion plates 39 are slidably connected inside the filter box 33. A telescopic cover is fixed to one side wall of each extrusion plate 39, and its other end is fixedly connected to the inner wall of the filter box 33. When the extrusion plate 39 moves, a gap is created between it and the interior of the filter box 33. The telescopic cover prevents dust from falling into the gap. Two guide rods 310 are fixed to one side wall of each extrusion plate 39. The other end of each guide rod 310 slides through the filter box 33 and extends to its exterior. A moving plate 311 is fixed to one end of each guide rod 310. A drive mechanism 312 is installed at the bottom of the filter box 33 to drive the two moving plates 311 to move synchronously in opposite directions. The drive mechanism 312 includes a drive mechanism rotatably connected to the bottom of the filter box 33 via a bearing. The drive shaft 3121 has a transmission rod 3122 fixed on its surface. Both ends of the transmission rod 3122 are rotatably connected to the connecting rod 3123 via bearings. The other ends of the connecting rods 3123 are rotatably connected to the corresponding moving plates 311 via bearings. In use, a motor is fixed at the bottom of the filter box 33. After the motor is started, the drive shaft 3121 is rotated, which in turn drives the transmission rod 3122 to rotate. When the transmission rod 3122 rotates, it can drive the two moving plates 311 to move synchronously in opposite directions with the cooperation of the two connecting rods 3123. After the moving plates 311 move, they can drive the extrusion plate 39 to move via the guide rod 310. When the two extrusion plates 39 move synchronously in opposite directions, they can extrude the dust collected inside the filter box 33 into blocks for subsequent cleaning.

[0018] like Figure 3 As shown, in some embodiments, two annular plates 313 fixed inside the buffer hopper 1 are provided between the two dust collection hoods 31, and a mesh cylinder 34 is fixed between the two annular plates 313. The annular plates 313 can provide auxiliary support for the mesh cylinder 34, and the mesh cylinder 34 can guide the falling material to avoid the material from splashing around the inner wall of the buffer hopper 1, so that the material is concentrated and falls onto the receiving plate 24 below, thereby improving the uniformity of force on the feeding buffer assembly 2.

[0019] like Figure 3 As shown, in some embodiments, two wear-resistant plates 4 are fixed inside the buffer hopper 1, and a wear-resistant plate 5 with a matching shape is fixed on the top of the buffer plate 23. The wear-resistant plate 4 can protect the bottom inner wall of the buffer hopper 1, while the wear-resistant plate 5 can protect the material plate 24, thereby enhancing the wear resistance of both. Both the wear-resistant plate 4 and the wear-resistant plate 5 are made of vulcanized ceramic rubber wear-resistant plate, which has excellent wear resistance, strong impact resistance, and a smooth surface that can reduce material blockage.

[0020] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
