Description

Technical Field

[0001] The invention relates to the technical field of petroleum coke sample processing, in particular to an automatic crushing and shrinking device for petroleum coke samples. Background Art

[0002] The petroleum coke sample is a representative part selected from the petroleum coke, which is used for various analyses and tests to understand the properties and quality of the petroleum coke. When testing the petroleum coke sample, crushing and reduction are important pretreatment steps. When reducing the petroleum coke sample, the divisor method is usually used. The divisor is a sample dividing tool with multiple parallel slots. The petroleum coke sample is evenly poured into the feed port of the divisor, so that the sample is evenly divided into two parts through the parallel slots and collected in the two receiving hoppers of the divisor. The sample in one of the receiving hoppers is discarded, and the sample in the other receiving hopper is used as the sample after reduction. If further reduction is required, the obtained sample can be poured into the divisor again for operation. The parallel slots of the divisor are used to divide the sample into two parts with equal probability, thereby halving the sample amount and ensuring that the sample after reduction is representative. However, the uniformity of the sample when the divisor is used to divide the sample cannot be guaranteed, and the sample needs to be taken out specifically before being divided equally, which is not conducive to direct reduction during the crushing process of the petroleum coke, and the efficiency of reduction is low.

DETAILED DESCRIPTION

[0034] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0035] Reference Figures 1 to 14 :

[0036] A petroleum coke sample automatic crushing and shrinking device comprises a crushing box 1, wherein a multi-stage crushing roller is arranged in the crushing box 1, a discharge port 11 is arranged at the bottom of the crushing box 1, a distribution pipe 2 is installed at the discharge port 11, the distribution pipe 2 comprises a connection port 21 at the top for connecting the discharge port 11, a first material pipe 22 and a second material pipe 23 extending obliquely to both sides are arranged below the connection port 21, a horizontally arranged conveying pipe 221 is connected to the bottom opening of the first material pipe 22, a spiral feeding roller 222 is coaxially installed in the conveying pipe 221; a guide plate 24 is rotatably installed in the connection port 21 of the distribution pipe 2, The shaft 241 provided at the bottom of the guide plate 24 is located at the connection between the tops of the first material pipe 22 and the second material pipe 23, and the shaft 241 extends to the outside of the material distribution pipe 2. The outside of the material distribution pipe 2 is provided with a driving unit 3 for driving the guide plate 24 to flip back and forth. When the driving unit 3 drives the guide plate 24 to flip back and forth in the connecting port 21 until it fits the side wall of the connecting port 21, the material entering the material distribution pipe 2 is intermittently guided into the first material pipe 22 and the second material pipe 23; the bottom of the second material pipe 23 is provided with a mounting frame 231, and a detachable sample collection box 232 (such as Figure 5 shown).

[0037] When used in the present application, the petroleum coke sample is first placed in the crushing box 1, and the multi-stage crushing rollers in the crushing box 1 start to operate, crushing the petroleum coke step by step, so that its particle size gradually decreases until it meets the requirements of subsequent reduction processing. The petroleum coke particles after crushing are discharged from the discharge port 11 at the bottom of the crushing box 1. The petroleum coke particles discharged from the discharge port 11 enter the connecting port 21 of the distribution pipe 2. During reduction, the drive unit 3 drives the guide plate 24 to start flipping back and forth, and the shaft 241 at the bottom of the guide plate 24 serves as the axis of rotation, allowing the guide plate 24 to continuously change its position in the connecting port 21. When the guide plate 24 flips to fit a side wall of the connecting port 21, the material entering the distribution pipe 2 will be guided to the corresponding first material pipe 22 or the second material pipe 23, and this is repeated, so that the material is intermittently distributed into the material pipes on both sides, achieving a preliminary reduction effect. The material falling into the first material pipe 22 will be transported out by the spiral feed roller 222 in the bottom conveying pipe 221 to the subsequent processing flow; and the material falling into the second material pipe 23 will directly fall into the sample collection box 232 installed at the installation frame 231, and be collected as the sample after reduction. If further reduction is required, just pour the sample in the collection box 232 into the crushing box 1 again, and repeat the above crushing and reduction process. In this embodiment, the guide plate 24 is driven by the driving unit 3 to flip back and forth in the connecting port 21, and the material can be divided into the first material pipe 22 and the second material pipe 23 more evenly. Compared with the problem that it is difficult to ensure uniformity in the two-part divider, this device can better ensure the uniformity and consistency of the two parts of the sample after each reduction, so that the reduced sample is more representative. The distribution pipe 2 of this embodiment is directly installed at the discharge port 11 of the crushing box 1, so that the reduction can be performed immediately after the petroleum coke crushing process is completed. There is no need to take out the sample and then operate it like a binary divider, which reduces the intermediate links, greatly improves the work efficiency of the reduction, and shortens the preprocessing time of the overall detection.

[0038] In order to realize the reciprocating turning of the guide plate 24, the following features are specifically provided:

[0039] A gear 242 is coaxially mounted on one end of the shaft 241 located outside the distribution pipe 2, and the driving unit 3 includes a limiting slide rail 31 horizontally mounted outside the distribution pipe 2 and located below the gear 242, and a sliding frame 32 slidably mounted on the limiting slide rail 31, and a tooth groove 321 is arranged on the upper side of the sliding frame 32, and the tooth groove 321 is meshed and connected with the gear 242; a horizontally extending connecting arm 33 is arranged at one end of the sliding frame 32, and a mounting seat 25 is arranged on the side of the distribution pipe 2 close to the connecting arm 33, and a turntable 34 is rotatably mounted on the mounting seat 25, and the axis of the turntable 34 is arranged parallel to the shaft 241, and a rocker arm 341 is rotatably mounted on the turntable 34, and the other end of the rocker arm 341 is rotatably connected to the connecting arm 33.

[0040] When the turntable 34 in this embodiment rotates, the rocker arm 341 installed on the turntable 34 will make a circular motion together with the turntable 34. Since the other end of the rocker arm 341 is rotatably connected to the connecting arm 33 of the sliding frame 32, the circular motion of the rocker arm 341 will drive the connecting arm 33 to make a reciprocating horizontal motion, and drive the sliding frame 32 to make a horizontal linear slide along the limiting slide rail 31. The tooth groove 321 set on the upper side of the sliding frame 32 is always in meshing state with the gear 242 at the end of the shaft 241. Therefore, when the sliding frame 32 slides back and forth on the limiting slide rail 31, the tooth groove 321 will drive the gear 242 to rotate alternately clockwise and counterclockwise. Because the gear 242 and the shaft 241 are coaxially installed, the reciprocating rotation of the gear 242 will drive the shaft 241 to rotate synchronously, and finally the guide plate 24 is caused to reciprocate and flip in the connection port 21 of the material distribution pipe 2 with the shaft 241 as the axis, and then the material entering the material distribution pipe 2 from the discharge port 11 of the crushing box 1 is intermittently guided to the first material pipe 22 and the second material pipe 23, so as to achieve the purpose of material reduction. In this embodiment, the stable rotation of the turntable 34 is converted into the precise reciprocating flipping action of the guide plate 24 through the transmission link of the rocker arm 341, the connecting arm 33, the sliding frame 32 and the gear 242, so that the rhythm of the material diversion to the material pipes on both sides is stable and controllable, which helps to obtain a more accurate proportion and better consistency of the reduction sample, and provides a reliable basis for the subsequent petroleum coke sample detection.

[0041] In order to drive the turntable 34 to rotate, the following features are specifically set:

[0042] One end of the spiral feed roller 222 is connected to the working end of the servo motor, and the other end of the spiral feed roller 222 extends to the outside of the conveying pipe 221 and is coaxially connected to the first synchronous wheel 223. One end of the rotating disk 34 is coaxially mounted with a second synchronous wheel 342 (such as Fig.14 As shown), the second synchronous wheel 342 is connected to the first synchronous wheel 223 through a synchronous belt 343.

[0043] In this embodiment, the spiral feed roller 222 is driven to rotate by a servo motor. As the spiral feed roller 222 rotates, the first synchronous wheel 223 located outside the conveying pipe 221 rotates synchronously. The first synchronous wheel 223 is connected to the second synchronous wheel 342 at one end of the turntable 34 through a synchronous belt 343. Relying on the flexible transmission characteristics of the synchronous belt 343, the first synchronous wheel 223 transmits power to the second synchronous wheel 342, prompting the second synchronous wheel 342 to rotate accordingly, thereby driving the turntable 34 to start rotating at a uniform speed. In this embodiment, the servo motor is used to drive the spiral feed roller 222 to transport materials, which is a power link that is originally required. Additional power is drawn to drive the turntable 34 to rotate. There is no need to configure a separate power source for the turntable 34, which avoids energy waste, improves the energy utilization efficiency of the entire device, and reduces operating costs.

[0044] In order to change the motion state between the guide plate 24 and the power source by changing the connection state between the connecting arm 33 and the sliding frame 32 during the continuous rotation of the turntable 34, so that the guide plate 24 can continuously transport the petroleum coke material to the first material pipe 22 when sample collection is not required, the following features are specifically set:

[0045] The connecting arm 33 is inserted into the guide hole 322 provided on the sliding frame 32 (such as Figure 6 As shown), a connection box 331 is provided at one end of the connection arm 33 located inside the sliding frame 32, and a connection hole 332 is provided at the bottom of the connection box 331; a horizontal frame 323 is provided inside the sliding frame 32, and the frame 323 is attached to the bottom of the connection hole 332, and a first through hole 324 (as shown) is provided on the frame 323 Fig.13 As shown), a connecting plug-in 35 is slidably installed at the first through hole 324. When the connecting plug-in 35 moves in the vertical direction to protrude from the upper surface of the frame plate 323 and is inserted into the connecting hole 332 at the bottom of the connecting box 331, the sliding frame 32 moves synchronously with the connecting arm 33.

[0046] A plurality of guide rods 325 extending along the length direction of the limiting slide rail 31 are provided at one end of the sliding frame 32 away from the connecting arm 33. The guide rods 325 are inserted into a guide sleeve 26 provided on the outside of the distribution pipe 2 away from the side of the mounting seat 25. A limiting head 326 is provided at one end of the guide rod 325 away from the sliding frame 32. A first spring 327 is sleeved on the guide rod 325. The first spring 327 elastically connects the limiting head 326 and the guide sleeve 26. The elastic force of the first spring 327 makes the sliding frame 32 fit to the guide sleeve 26.

[0047] In this embodiment, when conventional petroleum coke sample reduction work is required, the connecting plug 35 is in a state of protruding from the upper surface of the frame plate 323 and inserted into the connecting hole 332 at the bottom of the connecting box 331. At this time, the connecting arm 33 and the sliding frame 32 are connected as a whole through the connecting plug 35. Due to the action of the connecting plug 35, the sliding frame 32 and the connecting arm 33 move synchronously, so that the guide plate 24 flips back and forth, and the material is evenly divided into the first material pipe 22 and the second material pipe 23. When sample collection is not required, the connecting plug 35 moves downward in the vertical direction and disengages from the connecting hole 332 at the bottom of the connecting box 331. At this time, although the connecting arm 33 is in the guide hole 322, it loses its rigid connection with the sliding frame 32. The turntable 34 continues to rotate, and the rocker arm 341 drives the connecting arm 33 to reciprocate, but the sliding frame 32 does not move accordingly. Because the sliding frame 32 moves to fit the guide sleeve 26 under the elastic force of the first spring 327 and keeps the same position, its tooth groove 321 cannot drive the gear 242, and the guide plate 24 remains fixed, tilted and blocks the opening above the second material pipe 23, so that the petroleum coke material enters the distribution pipe 2 from the discharge port 11 of the crushing box 1, and is continuously transported to the first material pipe 22. This embodiment realizes the switching of two working modes through the existence of the connecting plug 35 and the connecting box 331. When the petroleum coke sample needs to be reduced and tested, the conventional reduction mode is adopted; and when the sample does not need to be collected, the material is continuously transported to the first material pipe 22, meeting the diverse needs of different working scenes.

[0048] In order to achieve a quick connection between the connection plug-in 35 and the connection box 331, the following features are specifically provided:

[0049] The connecting plug-in 35 includes an outer shell 351 fixedly installed below the first through hole 324 of the frame plate 323, and an insertion block 352 and a second spring 353 are arranged in the outer shell 351, and the elastic force of the second spring 353 pushes the insertion block 352 to move upward; an inclined surface 354 is arranged at one end of the insertion block 352 facing the guide hole 322 set in the sliding frame 32; a support rod 355 extending vertically downward is arranged at the bottom of the outer shell 351, and the support rod 355 is inserted in the second through hole 328 set at the bottom of the sliding frame 32. When the support rod 355 is in contact with the limiting slide rail 31, the height of the outer shell 351 enables the insertion block 352 to pass through the first through hole 324 and protrude from the upper surface of the frame plate 323.

[0050] When the connecting arm 33 of this embodiment is connected to the sliding frame 32, the connecting box 331 moves in close contact with the frame plate 323. When the connecting hole 332 at the bottom of the connecting box 331 approaches the plug-in block 352, since the plug-in block 352 is provided with an inclined surface 354 at one end facing the guide hole 322, the connecting box 331 will slightly press the plug-in block 352 down along the inclined surface 354, so that the second spring 353 is further compressed. When the connecting hole 332 is aligned with the plug-in block 352, under the elastic force of the second spring 353, the plug-in block 352 quickly pops up and is inserted into the connecting hole 332, thereby realizing the quick connection between the connecting plug 35 and the connecting box 331.

[0051] In order to achieve the purpose that the connection plug-in 35 can be quickly connected to the connection box 331 only when the sample collection box 232 is installed in the installation frame 231, the following features are specifically set:

[0052] Limiting slide rail 31 (such as Fig. 9 As shown in the figure, a third through hole 311 which vertically penetrates the limit slide rail 31 is provided at one end close to the guide sleeve 26. When the sliding frame 32 is fitted with the guide sleeve 26 under the elastic force of the first spring 327, the second through hole 328 and the third through hole 311 are in the same straight line, and a push rod 312 is slidably installed in the third through hole 311; a first hydraulic pipe 27 and a second hydraulic pipe 28 are fixedly installed on the outside of the material distribution pipe 2, a first piston push rod 271 is slidably installed in the first hydraulic pipe 27, and a second piston push rod 281 is slidably installed in the second hydraulic pipe 28. The first piston push rod 271 is coaxially arranged on the top Below the rod 312, the second piston push rod 281 is horizontally inserted in the socket 233 set in the installation frame 231, and the first hydraulic pipe 27 and the second hydraulic pipe 28 are connected through the connecting pipe 272. The first hydraulic pipe 27, the second hydraulic pipe 28 and the connecting pipe 272 are filled with hydraulic oil. When the sample collection box 232 is installed in the installation frame 231, the sample collection box 232 pushes the second piston push rod 281 into the second hydraulic pipe 28 and pushes the first piston push rod 271 to move upward. The first piston push rod 271 pushes the push rod 312 to move upward to the top end and is flush with the upper side of the limiting slide rail 31.

[0053] In this embodiment, when the sample collection box 232 is not installed in the installation frame 231, the second piston push rod 281 is not squeezed, the hydraulic oil in the first hydraulic pipe 27 and the second hydraulic pipe 28 is in a balanced state, the first piston push rod 271 is in a lower position, and the push rod 312 is partially located in the third through hole 311 under the action of gravity, and its top is lower than the upper side of the limit slide rail 31. At this time, the sliding frame 32 is in contact with the guide sleeve 26 under the elastic force of the first spring 327, and the second through hole 328 and the third through hole 311 are in the same straight line, but because the push rod 312 is in a lower position, it cannot affect the connection of the connecting plug 35. When the sample collection box 232 is installed in the installation frame 231, the sample collection box 232 pushes the second piston push rod 281 into the second hydraulic pipe 28. Since the first hydraulic pipe 27, the second hydraulic pipe 28 and the connecting pipe 272 are filled with hydraulic oil and are interconnected, the movement of the second piston push rod 281 will cause the flow of hydraulic oil, thereby pushing the first piston push rod 271 to move upward. After the first piston push rod 271 moves up, it pushes the push rod 312 to move up until the top of the push rod 312 is flush with the upper side of the limiting slide rail 31. At this time, the push rod 312 pushes the support rod 355 of the connecting plug-in 35 to move up, ensuring that the plug-in block 352 passes through the first through hole 324 and protrudes from the upper surface of the frame 323. It can be connected to the connecting box 331. This embodiment realizes precise control that the connecting plug-in 35 can be quickly connected to the connecting box 331 only when the sample collection box 232 is installed in the installation frame 231 through the ingenious design of the hydraulic system. This design avoids the misoperation of entering the conventional reduction mode when the sample collection box is not installed, ensuring the standardization of the reduction operation and the accuracy of sample collection.

[0054] In order to facilitate the separation of the connection box 331 and the connection plug-in 35 after the sample collection box 232 is removed from the installation frame 231, the following features are specifically provided:

[0055] A third spring 282 is disposed in the second hydraulic pipe 28 , and the third spring 282 elastically connects the second hydraulic pipe 28 and the second piston push rod 281 . The elastic force of the third spring 282 enables the second piston push rod 281 to pass through the insertion hole 233 and protrude from the inner wall of the installation frame 231 .

[0056] In this embodiment, when the sample collection box 232 is removed from the installation frame 231, the second piston push rod 281 moves into the installation frame 231 under the pressure of the hydraulic oil and the elastic force of the third spring 282, and the first piston push rod 271 drops accordingly, and the push rod 312 also drops under the action of gravity. At this time, even if the connecting arm 33 is inserted into the guide hole 322, since the push rod 312 is not in a position to push the connecting plug-in 35, when the connecting plug-in 35 moves to the second through hole 328 and the third through hole 311 are in the same straight line, the support rod 355 of the connecting plug-in 35 falls, and the connection relationship with the connecting box 331 is released, so that the guide plate 24 stops moving, ensuring that the connection in the conventional contraction mode can be performed only when the sample collection box 232 is installed.

[0057] In order to avoid the problem of the connection box 331 moving toward the inclined surface 354 of the insertion block 352 and pressing the insertion block 352 downward again to cause the connection state contact during the reciprocating movement of the connection arm 33, the following features are specifically set:

[0058] The upper side of the limiting slide rail 31 is provided with an inclined guide surface 313 (such as Fig. 9 As shown in the figure, the inclined guide surface 313 extends upward from the third through hole 311 of the limiting slide rail 31 to the end of the limiting slide rail 31 close to the turntable 34; when the support rod 355 of the connecting plug-in 35 fits the lower end of the inclined guide surface 313, the lower end of the inclined surface 354 on the plug-in block 352 is at the same horizontal height as the upper surface of the frame plate 323.

[0059] In this embodiment, when the connecting arm 33 reciprocates with the movement of the rocker arm 341 and the rotating disk 34, the sliding frame 32 moves synchronously along the limiting slide rail 31. Since the support rod 355 of the connecting plug 35 is attached to the inclined guide surface 313, when the sliding frame 32 moves, the support rod 355 will slide on the inclined guide surface 313. The inclined guide surface 313 extends upward from the third through hole 311 of the limiting slide rail 31 to the end of the limiting slide rail 31 close to the rotating disk 34, so that when the connecting arm 33 reciprocates, the connecting plug 35 will be slightly lifted as the position of the support rod 355 on the inclined guide surface 313 changes. This lifting action ensures that the inclined surface 354 of the plug-in block 352 is always higher than the upper surface of the frame plate 323 by a certain distance. Even if the connection box 331 accidentally approaches the inclined surface 354 of the plug-in block 352 during movement, the plug-in block 352 will not be pressed downward by contact with the inclined surface 354, thereby ensuring that the connection state between the connection plug-in 35 and the connection box 331 will not be accidentally released. In this embodiment, by providing the inclined guide surface 313, the posture of the connection plug-in 35 during the reciprocating movement of the connection arm 33 is changed, so that the inclined surface 354 of the plug-in block 352 is always higher than the upper surface of the frame plate 323, thereby avoiding the problem of the connection state being released due to the connection box 331 accidentally touching the plug-in block 352 during movement.

[0060] In order to prevent the ejector rod 312 from being separated from the third through hole 311, the following features are specifically provided:

[0061] A horizontal bottom plate 314 is disposed at the bottom of the top rod 312 , and a right-angle hanging plate 315 extending vertically downward is disposed at one side of the third through hole 311 at the bottom of the limiting slide rail 31 , and the horizontal side of the right-angle hanging plate 315 is located below the bottom plate 314 .

[0062] In this embodiment, when the top rod 312 moves down to the bottom of the bottom plate 314 and abuts against the right-angle hanging plate 315 , the top rod 312 can be restricted from moving downward, thereby preventing the top rod 312 from being separated from the third through hole 311 .

[0063] Working principle: The petroleum coke sample enters the crushing box 1, is crushed step by step by the multi-stage crushing rollers in the box, and is discharged from the discharge port 11 after the particle size is reduced. The material discharged from the discharge port 11 enters the distribution pipe 2. When the sample collection box 232 is not installed, the connection plug-in 35 cannot be connected to the connection box 331, the guide plate 24 is fixed, and the material is continuously transported to the first material pipe 22. When the sample collection box 232 is installed in the installation frame 231, the connecting arm 33 and the sliding frame 32 are connected to the driving unit 3 through the connection plug-in 35 to drive the guide plate 24 in the connection port 21 to flip back and forth, and the material is intermittently guided to the first material pipe 22 and the second material pipe 23 to achieve reduction. The sample after reduction falls into the sample collection box 232, and the material entering the first material pipe 22 is transported by the spiral feeding roller 222.

[0064] The above embodiments only express one or several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
