[0017] In the prior art, in the process of coke sampling, some processes use robots to transport materials, but under this process condition, there should not be too many sampling links, otherwise the robot working frequency is too high and the equipment efficiency is too low. In order to improve efficiency, some equipment and processes are reduced, which also affects the representativeness of the sample. The present invention realizes the transportation of materials through the transportation of track robots, realizes the plane layout of sample preparation units and refined sample units, reduces equipment links, reduces failure rates, reduces later maintenance costs, and greatly reduces construction costs. Improves the authenticity and representativeness of the sample. At the same time, the double-ring equipment process of the sample preparation unit and the refined sample unit composed of dual robots (track robots and fixed robots) enables the dual rings to each take responsibility, which is both independent and combined, flexible and diverse. The work of the dual robots greatly reduces the working frequency of the robots, improves efficiency, and the equipment process is comprehensive, which further improves the authenticity and representativeness of the samples. Under certain conditions, for example, when one ring is overhauled or fails, the refined sample work or the sample preparation work can be carried out alone.

[0018] Many components of the present invention are modular and unitized components, and each module realizes certain functions, which not only realizes intensification, but also no longer relies on robots in every link, and improves work efficiency. In the local area, the relevant equipment is combined to form a mechanical, electrical, and dust removal integration, which not only realizes certain functions, but also reduces the coupling degree between equipment, improves stability and reliability, and reduces the conversion between equipment, which can increase the sealing, reduce dust, and make dust removal easier.

[0019] Considering the environmental protection requirements, the present invention also introduces a dust removal unit, which is connected to each module to process the dust at each dust point. Each module is equipped with an independent electric air valve. When each module is working, the air valve is open, and when it is not working, the air valve is closed, which not only ensures the rationality of modularization, but also saves energy consumption. It ensures the cleanliness of the environment at the sampling site and protects human health.

[0020] In summary, the coke sampling and preparation system of the present invention makes the equipment and process settings for the sampling and preparation of coke samples reasonable, compact, modular and intensive, and fully realizes its integrity, economy, rationality, high efficiency and environmental protection.

[0021] Compared with the prior art, the advantages of the present invention are: The coke sampling system of the present invention is provided with a track robot and a fixed robot, which are used to transfer samples between the sample preparation unit, the refined sample unit and the discarded material unit. The units are connected and coherent, and the track robot and the fixed robot are responsible for the sample circulation, and the samples are not transported through the slide pipe and the belt conveyor as much as possible, thereby avoiding long-distance transportation of the conveyor belt, the slide pipe, etc., and reducing the maintenance cost caused by the blockage and wear of the slide pipe. At the same time, the track robot and the fixed robot are responsible for the sample circulation, which can allow the sample preparation unit and the refined sample unit to be at the same horizontal position, and the sample transportation drop is small, which reduces the breakage rate of coke particles during long-distance transportation, and further reflects the authenticity and representativeness of the sample.

[0050] In the refined sample unit, the jaw crushing module 35, the refined sample discarding module 25, the binary module 26, the 1 mm crushing module 27, the drying module 28, the automatic moisture meter 29, the grinding module 30, the packaging inkjet printer 31, the capping machine 32, and the pneumatic conveying module 33 are arranged around the fixed robot 34.

[0051] The discard unit, including the discard hopper 16, the discard transfer belt 17, the discard single bucket elevator 6, the total discard belt 5, etc., is arranged near the sample preparation unit. The discards of the refined sample unit are poured into the refined sample discard module 25 by the fixed robot 34, and then the refined sample total discard receiving bucket 254 in the refined sample discard module 25 is grabbed by the track robot 14 and poured into the discard hopper 16.

[0052] The dust removal unit includes a dust collector 40, an air lock 41, a conveying screw 42, a dust removal pipeline 43, a manual valve 44, and an electric valve 45. The dust removal unit is connected to each module to handle dust at each dust point. Each module is equipped with an independent electric air valve. When each module is working, the air valve is open, and when it is not working, the air valve is closed, which not only ensures the rationality of modularization but also saves energy consumption.

[0053] Through the above-mentioned arrangement of this embodiment, the sample preparation unit, the refined sample unit, and the discarded material unit are connected together by the track robot 14 and the fixed robot 34, realizing the equipment plane layout process, reducing civil engineering projects, reducing installation projects, and reducing the number of equipment, facilitating later use and maintenance, and reducing the damage of coke particles.

[0054] The coke sampling system and sampling method of this embodiment are introduced as follows with a more specific sampling method: 1. Sampling of sampling units After receiving the command, the material reclaimer 1 takes a certain amount of coke as a sample; the sample passes through the chute and enters the transfer belt 2, and evenly transports the sample to the rotary reducer 3. When the sample is reduced to the required amount, the sample enters the divider 4 through the chute; the remaining material enters the sampling and discarding belt 7, and the discarded material is sent to the coke conveyor belt 46, and the sampling process of the sampling unit is completed.

[0055] (II) Sample preparation unit The sample enters the divider 4 through the slide pipe, and is divided into two types of samples: moisture sample and analytical sample, and then enters the sample preparation unit on the first floor.

[0056] The moisture sample passes through the slide pipe and directly enters the moisture sample collection hopper 10, which is filled with a batch; the analytical sample passes through the slide pipe and enters the bidirectional belt 8, and enters the analytical sample collection hopper 9 in both forward and reverse directions, which is filled with a batch. The moisture sample collection hopper 10 and the analytical sample collection hopper 9 are both connected to the dust removal unit when unloading, and the electric valve 45 of the dust removal unit controls the action of the dust removal unit.

[0057] Next, the equipment process and equipment for moisture samples and analytical samples are introduced respectively.

[0058] 1. Analytical sample preparation process and equipment According to the instruction, the decrement scale of the analytical sample collection hopper 9 vibrates to feed the sample, and a certain amount of sample is weighed and loaded into the sample barrel 11. A sample barrel lifting mechanism 39 is provided below the sample barrel 11. The sample barrel lifting mechanism 39 and the sample barrel 11 thereon are below the analytical sample collection hopper 9, waiting for material to be received. When receiving the material, the sample barrel lifting mechanism 39 lifts the sample barrel 11 and fits it with the analytical sample collection hopper 9. After receiving the sample, the sample barrel 11 descends and waits for the track robot 14 to grab it. The sample barrel lifting mechanism 39 of other modules has the same function and will not be described later. When receiving the material, the electric valve 45 of the dust removal unit opens the suction, and the dust is sucked away by the dust removal pipeline 43 and enters the dust removal unit to prevent dust from overflowing.

[0059] The track robot 14 grabs the sample barrel 11 and pours it into the vibrating feeder 38 of the particle size screen 18, and then puts the sample barrel 11 back. The vibrating feeder 38 can evenly distribute the material to prevent the material from arching and uneven material flow. There is a wind hood on the hopper. The dust generated when the sample barrel 11 is poured is blocked by the wind hood and sucked away by the dust removal pipeline 43 and enters the dust removal unit. The subsequent distribution of the sample barrel 11 into the vibrating feeder 38 has a similar dust removal structure, which will not be described later.

[0060] The particle size screen 18 rotates, and the samples enter the weighing buckets 19 of different particle sizes according to their particle sizes, and the weighing results are uploaded.

[0061] Through weighing, conveying by the under-screen conveyor belt 20, and distribution by the tee 21, the ingredients are mixed together and respectively prepared into three kinds of samples: drum sample, thermal reaction sample, and industrial analysis sample according to proportion, and respectively enter the corresponding sample barrels 11. The excess samples enter the discarded material conveyor belt 17 of the discarded material unit through the under-screen conveyor belt 20.

[0062] The functions of the above components are to screen and detect the particle size ratio of the analysis sample, and to prepare various samples according to the particle size ratio. Various samples enter the sample barrel lifting mechanism 39 and the sample barrel 11 thereon respectively, waiting to enter the next process.

[0063] 1) The sample barrel 11 containing the drum sample is grabbed by the track robot 14 and poured into the vibrating feeder 38 on the drum machine 24, and then returns to put the sample barrel 11 back to its original position. The drum machine 24 runs, and when the requirements are met, it stops running, pours the material into the sample barrel 11 on the roller line 37, and sends the sample barrel 11 out. The track robot 14 grabs the sample barrel 11 and pours it into the vibrating feeder 38 of the post-drum particle size screen 12, and then returns to its original position. The function of the drum machine 24 is to flip the sample upside down and toss it to destroy the sample particles.

[0064] As the post-drum particle size screen 12 rotates, the samples enter the post-drum particle size weighing bucket 13 according to the particle size, and the weighing results are uploaded. The post-drum particle size weighing bucket 13 opens in sequence, passes through the post-drum discard belt 15, and enters the discard transfer belt 17 of the discard unit. The function of the above components is to screen the damaged sample particles, weigh them according to a certain particle size range, and detect the new ratio of the sample particle size according to the weighing results, so as to achieve the purpose of detecting the sample strength.

[0065] 2) The thermal reaction sample is grabbed by the track robot 14 and poured into the collector 36, and then transported to the laboratory for experiment by humans; the track robot 14 puts the sample barrel 11 back to its original place.

[0066] 3) The industrial analysis sample is grabbed by the track robot 14 and poured into the vibrating feeder 38 of the 40mm crusher 23, and then returns to put the sample bucket 11 back to its original position. The sample is evenly fed by vibration, and after crushing, it directly enters the 13mm crusher 22. After the crushing is completed in sequence, the sample with a particle size of 13mm enters the sample bucket 11. After it is full, the track robot 14 grabs it and pours it into the jaw crushing module 35. The track robot 14 puts the sample bucket 11 back to its original position. The sample enters the refined sample unit for further sample preparation. The remaining material is grabbed by the track robot 14 and poured into the discard hopper 16, enters the discard unit, and the sample bucket 11 returns to its original position. The industrial analysis sample enters the refined sample unit for further fine sample preparation.

[0067] 2. Moisture sample preparation process and equipment According to the instruction, the reduction scale under the moisture sample collecting hopper 10 vibrates and feeds, weighs a certain amount of sample and puts it into the sample barrel 11, the track robot 14 grabs the sample barrel 11 and pours it into the vibrating feeder 38 of the 40mm crusher 23, and the track robot 14 returns and puts the sample barrel 11 back to its original place. Vibration feeds evenly, and after crushing, the sample directly enters the 13mm crusher 22. After the crushing is completed in sequence, the sample with a particle size of 13mm enters the sample barrel 11. After filling, the track robot 14 grabs it and pours it into the jaw crushing module 35, and returns to the sample barrel 11. The moisture sample enters the refined sample unit for further sample preparation. The remaining material is grabbed by the track robot 14 and poured into the discard hopper 16, enters the discard unit, and returns to the sample barrel 11. The moisture sample enters the refined sample unit for further fine sample preparation.

[0068] After the above operations, the work of the sample preparation unit is completed. The modularization in the sample preparation unit is to combine the relevant equipment, simplify it, form the integration of mechanical, electrical and dust removal, simplify the material transfer process, ensure that dust does not leak, achieve certain functions, reduce the movement of the robot, improve work efficiency, and improve the stability and reliability of the process. At the same time, the sample preparation unit is also an independent production link. The sample particle size and mechanical strength have been measured. When the refined sample is not needed, the coke sample collection and preparation can be completed; when the refined sample unit needs to be repaired or fails, the sample can also be directly brought into the laboratory for manual sample preparation.

[0069] (III) Refined sample unit preparation Industrial analysis samples enter the sample refining unit for further sample preparation; moisture samples enter the sample refining unit for further sample preparation.

[0070] The sample preparation unit includes a modular jaw crushing module 35, a binary crushing module 26, a 1 mm crushing module 27, etc. First, each module is introduced as follows: like Figure 2As shown, the jaw crushing module 35 includes a jaw crusher bidirectional conveying belt 351, a jaw crusher 352 (6mm), and a jaw crusher rotary reducer 353. The entrance of the jaw crusher bidirectional conveying belt 351 is provided with a vibrating feeder 38, and is connected to a dust removal unit. The vibrating feeder 38 feeds the sample into the jaw crusher bidirectional conveying belt 351, which rotates forward, passes through the jaw crusher 352, and enters the sample barrel 11. The track robot 14 grabs the sample and pours it into the jaw crusher bidirectional conveying belt 351, reverses, and is reduced by the jaw crusher rotary reducer 353. The discarded material is grabbed by the track robot 14 through the sample barrel 11 and sent to the discard hopper 16. The required sample enters the sample barrel 11 and is grabbed by the fixed robot 34 to enter the next process of the refined sample ring. When crushing is not required, the vibrating feeder 38 feeds the sample into the jaw crusher bidirectional conveying belt 351, reverses, and is reduced by the jaw crusher rotary reducer 353. The function of the jaw crushing module 35 is to reduce and crush the sample to 6 mm, first crushing and then reducing it, and transporting the sample through the track robot 14 and the fixed robot 34. In this module, the sample refining unit and the sample preparation unit are connected, that is, they are connected and independent.

[0071] like Figure 3 As shown, the two-division module 26 includes a micro-vibration feeder 261 and a refined sample two-division device 262, and is connected to a dust removal unit. The sample to be divided into two is fed evenly by the micro-vibration feeder 261, and the refined sample two-division device 262 evenly divides the sample into two parts. The outlet of the refined sample two-division device 262 has a sample barrel 11, and is matched with a double barrel lifting mechanism 263. When unloading, the double barrel lifting mechanism 263 makes the sample barrel 11 close to the slide pipe. After receiving the material, the sample barrel 11 descends and waits for the fixed robot 34 to grab and enter the next process.

[0072] like Figure 4 As shown, the 1mm crushing module 27 includes a 1mm crusher 271 and a rotary divider 272, and is connected to a dust removal unit. A vibrating feeder 38 is provided at the entrance of the 1mm crusher 271; the sample to be crushed is fed evenly by the vibrating feeder 38, crushed into 1mm by the 1mm crusher 271, and enters the rotary divider 272. There is a sample barrel 11 at the outlet of the rotary divider 272, and a three-barrel lifting mechanism 273 is provided to match. When unloading, the three-barrel lifting mechanism 273 makes two sample barrels 11 close to the chute. After receiving the material, the sample barrel 11 descends and waits for the fixed robot 34 to grab it and enter the next process. The remaining material enters the discard unit through the middle chute.

[0073] The following will continue to introduce the equipment process flow based on the process of industrial analysis samples and the process of moisture samples.

[0074] 1. Industrial analysis samples The industrial analysis sample enters the jaw crusher bidirectional conveyor belt 351 in the jaw crusher module 35, rotates forward, and enters the jaw crusher 352. After crushing, it is reduced to 5 kg of sample and enters the sample barrel 11. The remaining material enters the refined sample total waste receiving barrel 254 in the refined sample waste module 25. The track robot 14 grabs it and pours it into the waste hopper 16 and enters the waste unit.

[0075] The fixed robot 34 grabs the sample barrel 11 containing 5 kg of sample, pours it into the 1 mm crushing module 27, and returns to the sample barrel 11; the sample is further crushed to 1 mm by the 1 mm crusher 271, and then enters the rotating divider 272 therein to reduce and separate two 0.3 kg industrial analysis samples.

[0076] 1) The fixed robot 34 grabs a sample barrel 11 containing 0.3 kg of sample, pours it into the binary module 26 , and returns to the sample barrel 11 .

[0077] The binary module 26 separates two samples of ≥100g, which are grabbed and flattened by the fixed robot 34 and placed in the drying module 28. After drying, they are respectively sent to the grinding module 30 and returned to the sample barrel 11. One of them is used as a cleaning sample, cleans the grinding module 30, and enters the refined sample discarding module 25. The other dried sample is ground by the grinding module 30 to make a 0.2mm sample; it is grabbed by the fixed robot 34 and placed in the binary module 26 and returned to the sample barrel 11.

[0078] The 0.2 mm sample is divided into two parts again by the two-part module 26 to make two samples of ≥ 50 g, which are transported by the fixed robot 34 and sent to the packaging inkjet printer 31 and returned to the sample barrel 11. Then, under the transportation of the fixed robot 34, the sample with inkjet coding is packaged and bottled, and the sample bottle cap is tightened by the capping machine 32, and enters the pneumatic conveying module 33 and is transported to the laboratory.

[0079] 2) Another sample barrel 11 containing 0.3 kg of sample is transported by the fixed robot 34, sent to the packaging inkjet printer 31, and returned to the sample barrel 11. Under the transportation of the fixed robot 34, the sample with inkjet coding is packaged and bottled, and the capping machine 32 tightens the sample bottle cap, enters the pneumatic conveying module 33, and is transported to the laboratory for storage and inspection.

[0080] 2. Moisture sample The moisture sample enters the jaw crusher bidirectional conveyor belt 351 in the jaw crusher module 35, reverses, and enters the jaw crusher rotary reducer 353 inside it, and 1 kg of sample is reduced and enters the sample barrel 11. The remaining material enters the refined sample discard module 25 and enters the discard unit.

[0081] The fixed robot 34 grabs a sample barrel 11 containing 1kg of sample, pours it into the binary module 26, and returns to the sample barrel 11. The binary module 26 separates two samples of 500g, which the fixed robot 34 grabs and puts into the automatic moisture meter 29, performs moisture detection online, and uploads the detection results. After the detection, the fixed robot 34 grabs the detected sample, pours it into the refined sample discard module 25, and returns to the sample barrel 11.

[0082] The waste materials generated in the refined sample unit are collected in the refined sample total waste material receiving bucket 254 in the refined sample waste material module 25, and the track robot 14 grabs them and pours them into the waste material hopper 16 and enters the waste material unit.

[0083] (IV) Abandoned material unit The function of the discard unit is to collect discards from each module of the refined sample ring, including a discard hopper 16, a discard transfer belt 17, a discard single bucket elevator 6, a total discard belt 5, a sampling discard belt 7 located in the sampling unit, a rear-drum discard belt 15 located in the sample preparation unit, and a refined sample discard module 25 located in the refined sample unit.

[0084] like Figure 5 As shown, the refined sample discard module 25 includes a lifting mechanism 251, a rotating brush 252, a refined sample discard hopper 253, a refined sample total discard receiving bucket 254 and a slide rail 255, and is connected to the dust removal unit. The rotating brush 252 is arranged above the refined sample discard hopper 253 and can be moved up and down by the lifting mechanism 251. The refined sample discard hopper 253 is arranged above the refined sample total discard receiving bucket 254, and the refined sample discard receiving bucket 254 is arranged above the slide rail 255. After the refined sample discard module 25 is started, the electric valve 45 of the dust removal unit is opened and works. The discarded materials from each module of the refined sample unit enter the sample barrel 11 (equivalent to the discarded material barrel, distinguished from the sample barrel 11 that receives the sample) and are caught by the fixed robot 34. The discarded materials are poured into the refined sample discarded material hopper 253, which is then rotated. When the mouth of the discarded material barrel is facing upward, the lifting mechanism 251 drives the rotating brush 252 deep into the discarded material barrel to brush away the dust and residual materials stuck to the barrel wall, clean the discarded material barrel, and the rotating brush 252 rises. The rotating discarded material barrel then pours the dust and residual materials into the refined sample discarded material hopper 253. The refined sample total discarded material receiving barrel 254 receives the materials, sends them out from the slide rail 255, and is grabbed by the track robot 14 and sent into the discarded material unit. It is no longer a long-distance belt conveyor.

[0085] The waste materials entering the waste hopper 16 enter the waste transfer belt 17 through the chute. In this way, all the waste materials are transported to the waste single bucket elevator 6 through the waste transfer belt 17, and then lifted to the total waste belt 5 on the second floor. The waste materials are then transferred to the coke conveying belt 46.

[0086] After the above process, the coke sample collection and preparation work is completed.

[0087] (V) Dust removal unit like Figure 6 As shown, the dust removal unit includes a dust collector 40, an air lock 41, a conveying screw 42, a dust removal pipeline 43, a manual valve 44 and an electric valve 45. The electric valve 45 is opened when the module is started, and the dust removal in the module starts to work, ensuring that the dust in each module or equipment does not overflow, and the dust is sucked away by the dust removal pipeline 43; the dust is concentrated in the dust collector 40 through the dust removal pipeline 43, and the dust is blocked and enters the ash hopper under the dust collector 40, unloaded by the air lock 41, enters the conveying screw 42, and is transported to the sampling and discarding belt 7, and then enters the coke conveying belt 46 and is transported away. The manual valve 44 can be adjusted to adjust the air volume required by each module or equipment, and then fixed, and the switch is controlled by the electric valve 45. The electric valve 45 is closed when the module is stopped, so that the air volume is reasonably distributed and energy saving and consumption reduction are reduced.

[0088] 6. Control Tree like Figure 7 As shown, the control tree of this embodiment is clear and logical, and the sample preparation unit and the sample refinement unit are independent of each other, free and flexible, and can work independently or jointly under the control of the master control.

[0089] As can be seen from the above, the coke sampling system and method of this embodiment make the sampling and preparation of coke samples reasonable, compact, modular and intensive, and fully realize its integrity, economy, rationality, high efficiency and environmental protection.
