[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 high-efficiency petroleum coke crusher. This device can be used to crush petroleum coke, and at the same time, it can use a filter screen to adsorb the dust generated when crushing petroleum coke, and can automatically clean the filter screen with adsorbed dust.

[0021] See Figure 1 A high-efficiency petroleum coke crusher includes a crusher body 1, a cleaning mechanism 2 is provided in front of the crusher body 1, the cleaning mechanism 2 includes a fixed box 201, two sets of support legs 5 are fixedly connected to the bottom surface of the crusher body 1, and each set of support legs 5 has two legs. The upper surfaces of three sliding plates 204 are fixedly connected to a push plate 6. By providing support legs 5, the support legs 5 can provide support force for the device, and the presence of push plate 6 can facilitate the application of pushing force to the three sliding plates 204.

[0022] See Figure 1 The back of the fixed box 201 is fixedly connected to the front of the crusher body 1. Three sliding plates 204 are slidably connected inside the fixed box 201. The outer surface of each sliding plate 204 is in contact with the inner wall of the fixed box 201. A connecting pipe 4 is fixedly connected to the left side of the fixed box 201. The right end of the connecting pipe 4 is fixedly connected to the left side of the crusher body 1. A fixing block 3 is fixedly connected to the left side of the crusher body 1. The inner wall of the fixing block 3 is fixedly connected to the outer surface of the connecting pipe 4. By setting the connecting pipe 4, the connecting pipe 4 can draw air and dust from inside the crusher body 1 into the fixed box 201 with the help of the fixed box 201 which is in a negative pressure state. The presence of the fixing block 3 can provide support for the connecting pipe 4.

[0023] See Figure 2 and Figure 3Each sliding plate 204 has a filter screen 205 fixedly connected to its inner wall. The inner wall of the fixed box 201 has two sets of fixed plates 206 fixedly connected, with two plates in each set. The inner wall of each fixed plate 206 is rotatably connected to a short shaft 209. Cleaning plates 207 are fixedly connected to one end of two short shafts 209 and both ends of the other two short shafts 209. A support base 8 is fixedly connected to the right side of the fixed box 201. An air pump 7 is fixedly connected to the upper surface of the support base 8. An air extraction pipe 11 is fixedly connected to the input end of the air pump 7. The end of the air extraction pipe 11 near the fixed box 201 is fixedly connected to the right side of the fixed box 201. An air outlet pipe 12 is fixedly connected to the output end of the air pump 7. By setting up the air pump 7, the power generated by the operation of the air pump 7 can be used to extract the gas inside the fixed box 201 through the air extraction pipe 11, so that the inside of the fixed box 201 is in a negative pressure state.

[0024] See Figure 3 and Figure 4 A stepper motor 202 is fixedly connected to the front of the fixed box 201. A long shaft 208 is fixedly connected to the output end of the stepper motor 202. Two sets of transmission gear belts 210 are fixedly connected to the outer surface of the long shaft 208 and the outer surfaces of the two sets of short shafts 209. Two connecting plates 203 are fixedly connected to the front of the fixed box 201. The outer surface of the long shaft 208 is rotatably connected to the inner wall of the two connecting plates 203. By setting the connecting plates 203, the connecting plates 203 can provide support for the long shaft 208, making the rotation of the long shaft 208 more stable.

[0025] See Figure 1 and Figure 2 Each set of transmission gear belts 210 consists of two units. A rectangular plate 10 is fixedly connected to the front of the crusher body 1. A storage box 9 is set above the rectangular plate 10. The bottom surface of the storage box 9 is in contact with the upper surface of the rectangular plate 10, and the upper surface of the storage box 9 is in contact with the bottom surface of the fixed box 201. By setting up the rectangular plate 10, the rectangular plate 10 can provide an installation position for the storage box 9, and the storage box 9 can store the cleaned dust.

[0026] Working principle: During operation, the petroleum coke to be crushed is transported into the crusher body 1 for crushing. Then, the air pump 7 is controlled to operate. The air pump 7 extracts the gas from the fixed box 201 through the air extraction pipe 11, creating a negative pressure state inside the fixed box 201. Under the action of negative pressure, the air inside the crusher body 1 and the dust generated during the crushing of petroleum coke are extracted through the connecting pipe 4, thereby drawing the dust into the fixed box 201. The air passes through the three-layer filter screen 205 into the air pump 7 and is finally delivered to the outside through the air outlet pipe 12. Dust will be adsorbed by the filter screen 205. When the filter screen 205 needs to be cleaned, press down on the push plate 6. The push plate 6 will push the sliding plate 204 downward. The downward sliding of the sliding plate 204 will move the filter screen 205 fixed on the inner wall to the position where it contacts the cleaning plate 207. It is important to understand that there is friction between each sliding plate 204 and the fixed box 201, and the friction between the three sliding plates 204 and the fixed box 201 is greater than the sum of the weights of the three filter screens 205, the three sliding plates 204, and the push plate 6. Therefore, the sliding plate 204 will not move without external force. Under intervention, it will remain on the left side of the extraction pipe 11. Then, the stepper motor 202 is controlled to run. The power generated by the stepper motor 202 drives the long shaft 208 to rotate. When the long shaft 208 rotates, it transmits power to the short shaft 209 via the transmission gear belt assembly 210. It's important to understand that each transmission gear belt assembly 210 consists of two gears and a toothed belt. One gear is fixed to the long shaft 208, and the other gear is fixed to the short shaft 209. Therefore, the rotational power on the long shaft 208 can be transmitted to the short shaft 209 via the toothed belt. The cleaning plate 207 can be rotated in one step, and the dust in the filter screen 205 can be cleaned by the cleaning plate 207. The cleaned dust will fall into the storage box 9. It should be noted that the two short shafts 209 on the far left and far right are only fixed with the cleaning plate 207 at one end, while the two short shafts 209 in the middle are fixed with the cleaning plate 207 at both ends. Therefore, a total of six cleaning plates 207 can effectively clean the six sides of the three filters 205, thereby effectively avoiding the problem of needing to manually clean the dust in the filters 205 regularly during use.

[0027] 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.
