[0002] Petroleum coke is a product obtained by separating light and heavy oils from crude oil through distillation, and then further processing the heavy oils through thermal cracking. In appearance, coke is an irregularly shaped, black block of varying sizes. Petroleum coke requires grinding and grading equipment for processing.
[0003] In the use of existing grinding and classifying devices, most of them do not have the function of preventing filter screen clogging. As a result, during the classification of petroleum coke, petroleum coke is prone to adhering to the filter screen, affecting the smooth flow of airflow, thereby reducing the processing efficiency of petroleum coke and thus reducing the practicality of the device.
[0004] To address these issues, we have provided a petroleum coke grinding and grading device. Utility Model Content

[0019] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.
[0020] This embodiment provides a petroleum coke grinding and grading device. This device, by setting up a frame 1 and a processing mechanism 2, can separate petroleum coke from the screening screen 204, thereby avoiding affecting the smoothness of airflow.
[0021] See Figure 1 and Figure 4 A petroleum coke grinding and grading device includes a frame 1. A processing mechanism 2 is installed inside the frame 1. The processing mechanism 2 includes a grading box 201. The bottom surface of the grading box 201 is fixedly connected to the inner bottom wall of the frame 1. A grinding jar 210 is rotatably connected inside the frame 1. A conveying pipe 211 is rotatably connected to the right end of the grinding jar 210, and the right end of the conveying pipe 211 extends into the interior of the grading box 201. A rack ring 212 is fixedly installed on the outer surface of the grinding jar 210. A concave frame 213 is fixedly installed on the inner bottom wall of the frame 1. A connecting... Gear 214, the outer surface of which meshes with the outer surface of rack ring 212. A rotary motor 215 is fixedly installed on the left side of concave frame 213. The output end of rotary motor 215 is fixedly connected to the left end of connecting gear 214. The power provided by rotary motor 215 drives connecting gear 214 to rotate, thereby driving rack ring 212 and grinding jar 210 to rotate. This causes the grinding balls inside grinding jar 210 to collide and grind the petroleum coke, thus achieving the function of grinding petroleum coke.
[0022] See Figure 1 , Figure 2 and Figure 4The inner wall of the grading box 201 is fixedly equipped with a dustproof net 202 and two sets of connecting springs 203. On the side of the two sets of connecting springs 203 that are close to each other, a screening net 204 is fixedly installed. The holes on the right screening net 204 are smaller than the holes on the left screening net 204, so that the airflow can carry the powdered petroleum coke into the interior of the grading box 201, and the screening net 204 can be used to classify the petroleum coke. The left end of the grinding tank 210 is rotatably connected to the feed pipe 216. The outer surface of the feed pipe 216 is fixedly connected to the air inlet pipe 217. The installation of the feed pipe 216 makes it convenient for workers to fill the interior of the grinding tank 210 with the petroleum coke to be ground. The installation of the air inlet pipe 217 makes it convenient to fill the interior of the grinding tank 210 with gas.
[0023] See Figure 1 , Figure 2 and Figure 3 A rotating motor 205 is fixedly installed on the upper surface of the grading box 201. A rotating shaft 206 is fixedly installed at the output end of the rotating motor 205. A turntable 207 is fixedly installed at the bottom end of the rotating shaft 206. A connecting bearing 221 is fixedly installed on the inner top wall of the grading box 201. The bottom surface of the inner ring of the connecting bearing 221 is fixedly connected to the upper surface of the turntable 207. The installation of the connecting bearing 221 plays a role in stabilizing the turntable 207, thereby preventing the turntable 207 from shaking when rotating, and thus ensuring the stability of the turntable 207.
[0024] See Figure 1 and Figure 3 A connecting column 208 is fixedly installed on the bottom surface of the turntable 207. Two locking blocks 218 and two locking frames 219 are fixedly installed on the bottom surface of the grading box 201. Each locking block 218 is engaged inside the locking frame 219. The installation of the locking blocks 218 and the locking frames 219 plays the role of locking the grading box 201, thereby preventing the grading box 201 from opening on its own and ensuring the stability of the grading box 201.
[0025] See Figure 2 and Figure 3 A movable frame 209 is provided below the turntable 207. The inner wall of the movable frame 209 is slidably connected to the outer surface of the connecting column 208. The two ends of the movable frame 209 are in contact with the outer surfaces of the screening screen 204. Two limiting frames 222 are fixedly installed on the inner top wall of the grading box 201. The inner wall of each limiting frame 222 is slidably connected to the outer surface of the movable frame 209. The installation of the limiting frames 222 plays a role in limiting the movement trajectory of the movable frame 209, thereby preventing the movable frame 209 from deviating from the movement trajectory when moving, and thus ensuring the stability of the movement of the movable frame 209.
[0026] See Figure 1 and Figure 2A vibration motor 223 is fixedly installed on the upper surface of the grading box 201. Two sets of telescopic columns 220 are fixedly installed on the inner wall of the grading box 201. The telescopic end of each telescopic column 220 is fixedly connected to the outer surface of the screening screen 204. The installation of the telescopic columns 220 plays a role in restricting the movement trajectory of the screening screen 204, thereby ensuring the stability of the movement of the screening screen 204.
[0027] Working principle: During use, the worker fills the grinding jar 210 with petroleum coke to be ground through the feed pipe 216. Then, the power provided by the rotary motor 215 drives the connecting gear 214 to rotate, which in turn drives the rack ring 212 to rotate, which in turn drives the grinding jar 210 to rotate. This causes the grinding jar 210 to rotate, resulting in the petroleum coke and grinding balls inside rotating and grinding the petroleum coke through impact. After grinding, the worker injects gas into the grinding jar 210 through the air inlet pipe 217. The gas carries the ground petroleum coke through the conveying pipe 211 into the classifying box 201, where it is screened. 204. The petroleum coke is graded. During the grading process, the power provided by the rotating motor 205 drives the rotating shaft 206 and the turntable 207 to rotate. This causes the turntable 207 to drive the connecting column 208 to rotate. In turn, the connecting column 208, under the restriction of the limit frame 222, drives the moving frame 209 to move back and forth. The moving frame 209, in conjunction with the elastic force of the connecting spring 203, pushes the two screening screens 204 to vibrate back and forth. This causes the petroleum coke on the screening screens 204 to slide off and detach from the screening screens 204. At the same time, the vibration force of the vibration motor 223 further detaches the petroleum coke from the screening screens 204, preventing the screening screens 204 from clogging and affecting the smooth flow of air.
[0028] 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.
