Description

Technical Field

[0001] The invention relates to the technical field of sampling equipment, and in particular to a sampling device and a quick-loading bulk material system. Background Art

[0002] The bulk material fast loading system is a modern technical equipment for loading bulk materials efficiently and automatically. It is used to load bulk materials into cars or train cars quickly, accurately and quantitatively. The bulk material fast loading system plays a vital role in modern industrial logistics and bulk material handling. With the continuous advancement of technology and the growth of market demand, the advantages of this system are becoming increasingly prominent, and its application scope is also expanding.

[0003] The main components of the bulk material quick loading system include silos, conveying equipment, loading equipment, control systems and other auxiliary equipment. Silos are containers for temporary storage of bulk materials, usually equipped at the starting end of the conveying equipment. They can temporarily store a large amount of materials and feed them to the conveying system as needed. Conveying equipment refers to various types of conveyors used to transfer bulk materials released from silos to loading and unloading points. Loading equipment refers to feeders and various telescopic arms, loading and unloading chutes, levelers and other equipment used to stack the conveyed materials in the appropriate position of the carriage.

[0004] The sampling process in bulk commodity transactions is not only a basic step in quality control, but also an important mechanism to ensure fair, transparent and efficient transactions. Through scientific sampling and testing processes, a reliable material basis can be provided for both parties to the transaction. For production units, systematic collection and analysis of sample data can help decision makers adjust buying and selling strategies, adjust prices, reduce risks, etc.

[0005] In the related art, samples are taken directly from the silo by purchasing and using special sampling equipment. The disadvantage is that it will destroy the integrity of the silo and the sampling is less representative.

[0006] Related technologies also utilize existing belt conveyor sampling equipment on the market to collect samples from the transfer belt conveyor. The disadvantage is that an additional sampling belt conveyor needs to be arranged, which increases the complexity of the system. It is not suitable for compact quick-installation systems or quick-installation systems without transfer conveyors, which increases the cost of sampling. Summary of the invention

[0050] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0051] The sampling device of the embodiment of the present invention includes: a material taking unit 1, a crushing unit 2, a sampling and returning unit 3 and a sample storage unit 4. The material taking unit 1 is arranged on the funnel 53 of the quick-loading bulk material system 5 for taking materials. The material taking unit 1 is connected to the crushing unit 2 to crush the material and then sort it. The sampling and returning unit 3 is connected to the crushing unit 2 to sample the sorted material. The sampling and returning unit 3 returns the sampled material to the quick-loading bulk material system 5. The sample storage unit 4 is suitable for receiving the sampled material of the sampling unit and storing the sampled material.

[0052] Specifically, Figures 1 to 11 As shown, the material taking unit 1 is arranged above the funnel 53, and the material taking unit 1 extends into the funnel 53 to take materials. During the material loading process, the material is sampled while loading. The sampled material is highly representative, and there is no need to stop loading to take samples separately, so that the goods are loaded and shipped out of the factory with high efficiency. The other end of the material taking unit 1 is connected to the crushing unit 2 to crush the material. The crushing unit 2 can be an existing crusher.

[0053] For example, the crushing unit 2 can be equipped with different types of crushers according to the actual particle size required.

[0054] The sampling and returning unit 3 is connected to the crushing unit 2 to sample the sorted material, and the sampling and returning unit 3 returns the sampled material to the fast-loading bulk material system 5. The sampled sample is transported by the sampling and returning unit 3 to the sample storage unit 4 for storage. For example, the sample for testing is stored in the sample storage bottle 43.

[0055] The sampling device of the embodiment of the present invention is convenient for sampling the quick-loading bulk material system 5 by setting the material taking unit 1 on the funnel 53, thereby reducing the sampling cost. The material samples after sampling are sent to the crushing unit 2, the cutting and returning unit 3 and the sample storage unit 4 in sequence, and the collected samples are directly packaged and stored, shortening the transportation and processing route and reducing the impact of the transportation process on the quality. No manual sampling is required, and the labor cost is reduced. At the same time, during the process of loading materials, sampling can be carried out while the vehicle is being loaded, and the sampled materials are highly representative. There is no need to stop loading to perform sampling separately, so that efficient loading of goods for shipment can be achieved. The sampling device is arranged on the funnel 53, and there is no need to invest in the construction of an independent sampling room, thereby reducing costs.

[0056] In some embodiments, the material taking unit 1 includes a frame 11, a lifting component 12, a sampling head 13 and a discharge component 14. The frame 11 is arranged above the funnel 53 of the quick-loading bulk material system 5. The frame 11 is provided with a lifting component 12, and the telescopic end of the lifting component 12 is connected to the sampling head 13 so that the sampling head 13 extends into or out of the funnel 53 for sampling. The frame 11 is provided with a sample outlet 111.

[0057] The unloading component 14 is disposed on the frame 11 to push the material in the sampling head into the sample outlet 111 to unload the material. The sample outlet 111 of the frame 11 is connected to the crushing unit 2 .

[0058] Specifically, Figures 1 to 11 As shown, the height direction of the frame 11 is the up-down direction, the width direction of the frame 11 is the left-right direction, and the frame 11 is provided with a lifting component 12, which is extended and retracted in the up-down direction to move the sampling head 13 in the up-down direction, so that the sampling head 13 moves in the up-down direction, for example, the sampling head 13 moves downward to extend into the funnel 53 to sample the material. Or the sampling head 13 moves upward to extend out of the funnel 53, when the sampling head 13 is not moving, that is, when the lifting component 12 is not extended and retracted in the up-down direction and the sampling head 13 is fixed, the unloading component 14 pushes the material in the sampling head into the sample outlet 111 to unload the material.

[0059] The sampling device of the embodiment of the present invention can randomly sample materials by setting a lifting component 12, a sampling head 13 and a unloading component 14, avoid the sampled materials from being concentrated in a certain area of ​​the silo 51, sample the materials evenly, and improve the representativeness of the sampled materials. At the same time, there is no need to set up special sampling equipment and sampling buildings, which reduces costs and avoids the poor representativeness of the sampling equipment for the silo 51, which affects the monitoring of the quality of the loaded materials.

[0060] In some embodiments, the discharging member 14 includes a discharger 141 and a first telescopic member 142. The first telescopic member 142 is connected to the discharger 141 to move the discharger 141 in the width direction of the frame 11 to unload the material on the sampling head. Wherein, the sampling head 13 is in a U shape with openings at the upper part and both ends, and the discharger 141 is in a ┌ shape or a 冂 shape with an opening at the lower end.

[0061] Specifically, as Figures 1 to 11 shown, the discharger 141 is in a ┌ shape or a 冂 shape with an opening at the lower end, and the sampling head 13 is in a U shape with openings at the upper part and both ends. Furthermore, the discharger 141 cooperates with the sampling head 13 to perform sampling and sample discharging.

[0062] For example, when sampling, at this time, the sampling head 13 and the discharger 141 enclose a cuboid or a cube shape. The sampling head 13 moves downward to extend into the funnel 53 to collect the material. After the collection is completed, the sampling head 13 moves upward. After rising, at this time, the sampling head 13 and the discharger 141 enclose a cuboid or a cube shape. At this time, the discharger 141 moves to the right to push the material on the sampling head 13 to the sample outlet 111 to unload the material. Furthermore, manual sampling and sample taking are not required, reducing the labor intensity.

[0063] Furthermore, the discharging member 14 further includes a guide rail 1433 disposed on the frame 11. The telescopic end of the first telescopic member 142 is movably disposed on the guide rail 1433. The guide rail 1433 extends in the left - right direction, and the telescopic end of the first telescopic member 142 is movably disposed on the guide rail 1433. The guide rail 1433 guides and limits the movement of the first telescopic member 142 in the left - right direction, ensuring that the trajectory of the discharger 141 in the left - right direction is straight and making the movement of the discharger 141 in the left - right direction smoother.

[0064] In some embodiments, the funnel 53 is provided with an opening for the sampling head 13 to extend into the funnel 53 for sampling.

[0065] The material taking unit 1 further includes air lock valves 15 and air springs 16 rotatably disposed on both sides of the opening. The air springs 16 are pivotally connected to the air lock valves 15. The air springs 16 expand and contract to rotate the air lock valves 15 to open or close the opening.

[0066] Wherein, during sampling, the lifting member 12 extends to push the air lock valve 15 open by the sampling head 13 and extend into the funnel 53.

[0067] For example, when the sampling head 13 moves downward, it will contact the air lock valve 15 and push it open. When the sampling head 13 moves upward to the in - place position after sampling, the air lock valve 15 is pushed back by the air spring 16 to close. To prevent external objects from entering through the opening above the funnel 53 and prevent the dust in the funnel 53 from overflowing, improving the stability and safety during sampling.

[0068] Furthermore, the lifting component 12 includes a lifting member 121 and a lifting frame 122. The lower end of the lifting frame 122 is connected to the sampling head 13, and the upper end of the lifting frame 122 is connected to the lifting member 121. The lifting member 121 can be a lifting cylinder, that is, a hydraulic cylinder. During sampling, the lifting cylinder extends to drive the lifting frame 122 to descend. The sampling head 13 is connected to the bottom of the lifting frame 122. The sampling head 13 is the same width as the material flow, and the opening is larger than 3 times the nominal particle size of the material. The sampling head 13 is a "U"-shaped flat bottom structure with openings at the top and both ends to ensure that it can connect to the entire cross-section of the material flow. When the sampling head 13 continues to descend until it is completely inserted into the material flow and the sampling head 13 is instantly filled, the lifting cylinder changes direction and rises.

[0069] When the lifting frame 122 and the sampling head 13 are lowered, they will contact the air lock door 15 and push it open. When the lifting frame 122 and the sampling head 13 are raised to the right position after sampling, the air lock door 15 is pushed back and closed by the air spring 16.

[0070] Further, the first telescopic component 142 includes a connecting frame 1421, a translation motor 1422 and a fixed rack 1423. The output end of the translation motor 1422 is provided with a gear, and the fixed rack 1423 is arranged on the frame 11. The translation motor 1422 rotates to drive the gear to rotate. Through the engagement of the fixed rack 1423, the connecting frame 1421 is driven to move in the left and right directions. At this time, the translation motor 1422 also moves in the left and right directions. For example, the connecting frame 1421 is driven to move from the discharge end to the sampling end, that is, the connecting frame 1421 is driven to move from the top of the sample outlet 111 to the top of the opening of the funnel 53. The connecting frame 1421 is used to connect the discharger 141 and the translation motor 1422, and the discharger 141 moves to the sampling end. The discharger 141 is a "┌"-shaped structure, and the upper top plate covers the translation guide rail 1433 to ensure that the track of the discharger 141 is straight. After sampling, the sampling head 13 rises to its position, the lifting cylinder locks the position, the translation motor 1422 starts, and drives the discharger 141 to move from the sampling end to the discharge end. The vertical plate of the discharger 141 pushes the material in the sampling head 13 to flow to the discharge port, and the top plate on the discharger 141 presses the sample material to prevent it from accumulating and overflowing the sampling head 13 during pushing. The discharger 141 pushes all the sample materials in the sampling head 13 into the sample outlet 111.

[0071] In some embodiments, the cutting and returning unit 3 includes a dividing chute frame 31, a returning conveyor 32, a fixing frame 33, a second telescopic component 34 and a sampling component 35. A returning channel 311 is provided in the dividing chute frame, and the lower end of the returning channel 311 is connected to the returning conveyor 32.

[0072] An opening is provided on the side of the return channel 311, the fixed frame 33 is connected to the reduction chute frame 31, and the fixed frame 33 is provided with a second telescopic component 34, the second telescopic component 34 is connected to the sampling component 35, the second telescopic component 34 is extended to allow the sampling component 35 to extend into the return channel 311, and the fixed frame 33 is provided with a sample unloading channel 312, the second telescopic component 34 is contracted to allow the sampling component 35 to move to the top of the sample unloading channel 312 for sample unloading.

[0073] Specifically, Figures 1 to 11 As shown, the side of the contraction chute frame 31 is opened for the sampling component 35 to enter and intercept the sample. The second telescopic component 34 is telescopic in the left and right directions to enable the sampling component 35 to move in the left and right directions. For example, the sampling component 35 moves to the left to intercept the material, and the sampling component 35 moves to the right to unload the material, so that the material is unloaded into the unloading channel 312.

[0074] The material sample is discharged from the crushing unit 2 into the return channel 311 of the reduction chute frame 31. The side of the reduction chute frame 31 is open for the sampling component 35 to enter and intercept the sample. The lower end of the reduction chute frame 31 is connected to the return conveyor 32. The material not intercepted by the sampling component 35 falls into the return conveyor 32 as discarded material. The outlet of the return conveyor 32 is connected to the head funnel 53 of the loading system, and the discarded material returns to the loading material flow channel and falls back into the carriage. The intercepted material sample enters the sample storage unit 4 through the unloading channel 312.

[0075] Furthermore, the sample material is evenly pushed out by the discharger 141 through the sample outlet 111 and enters the crushing unit 2, where the large particle size material is crushed into small particle size material, which is convenient for the next step of reduction operation. In actual application, a crusher can be selected according to the actual particle size. In some cases, a crusher may not be used, but the sample directly enters the sample cutting and returning unit.

[0076] In some embodiments, the sampling component 35 includes a cutter body 351, a spring 352, a bottom plate 353, and a discharge stopper 354 disposed on the fixing frame 33.

[0077] The cutter body 351 is provided with a material receiving hole 3511, one end of the spring 352 is connected to the bottom plate 353, and the bottom plate 353 can be extended into or out of the bottom of the material receiving hole 3511 for sampling or unloading, wherein the second telescopic component 34 can be extended to allow the cutter body 351 to extend into the return channel 311 for sampling, and the second telescopic component 34 can be contracted to allow the cutter body 351 to move to the top of the unloading channel 312 so that the unloading stopper 354 can extend into the material receiving hole 3511 and push the bottom plate 353 out of the material receiving hole 3511 for unloading.

[0078] Specifically, Figures 1 to 11As shown, the cutter body 351 is provided with a material receiving hole 3511, and the bottom plate 353 can move on the cutter body 351. When the bottom plate 353 moves relative to the cutter body 351, the bottom plate 353 can block the lower end of the material receiving hole 3511 so that the material receiving hole 3511 carries the material, or the bottom plate 353 moves away from the material receiving hole 3511 to unload the material in the material receiving hole 3511. For example, the bottom plate 353 moves to the right to extend into the lower end of the material receiving hole 3511 to block the lower end of the material receiving hole 3511 for cutting the sample, and the spring 352 keeps the bottom plate 353 moving to the right all the time, that is, the spring 352 provides a normally closed torque to close the bottom of the material receiving hole 3511 of the cutter body 351.

[0079] The spring 352 can keep the bottom plate 353 at the lower end of the material receiving hole 3511 at all times, and the second telescopic component 34 enables the cutter body 351 to move in the left and right directions. When the cutter body 351 is at the rightmost end of the moving trajectory, or the cutter body 351 moves to the right above the sample unloading channel 312, the bottom plate 353 contacts the unloading stopper 354, and then the cutter body 351 continues to move to the right. At this time, the bottom plate 353 is pushed by the unloading stopper 354 to move to the left to release the material in the material receiving hole 3511.

[0080] In some embodiments, the sample storage unit 4 includes a storage tube 41 and a sample collector 42. The storage tube 41 is connected to the fixed frame 33, and the inlet of the storage tube 41 is connected to the sample unloading channel 312. The outlet of the storage tube 41 faces the sample collector 42. The sample collector 42 is provided with multiple sample bottles 43 to collect samples.

[0081] Specifically, Figures 1 to 11 As shown, the sample collector 42 may be an existing sample collector 42 , and a plurality of sample storage bottles 43 are arranged above the sample collector 42 to collect samples outputted from the sample unloading channel 312 .

[0082] Furthermore, the sample storage unit 4 can also be provided with a cap lifting device, a cap hanging device, a cap screwing device and a bottle clamping device, so that the input sample storage bottle 43 can complete the process of cap lifting, cap hanging and cap screwing in sequence.

[0083] Furthermore, the sample storage unit 4 may also be provided with a sealing device and a labeling device, so that the sample storage bottle 43 after the cap is screwed on sequentially enters the sealing device and the labeling device, and performs the processes of lifting the cap, hanging the cap, screwing the cap, sealing, labeling, etc., and completes the sample storage of the sample storage bottle 43 sequentially.

[0084] In some embodiments, the material taking unit 1 further includes a protective cover disposed above the opening of the funnel 53 to prevent the sampling head 13 from being mechanically damaged by the outside world during the sampling process.

[0085] The quick-loading bulk material system 5 of the embodiment of the present invention comprises:

[0086] A silo 51, a feeder 52 and a hopper 53, wherein the silo 51 is connected to one end of the feeder 52, and the other end of the feeder 52 is connected to the inlet of the hopper 53;

[0087] A loading chute 54 and a dump truck 55, wherein the inlet of the loading chute 54 is connected to the outlet of the hopper 53, and the outlet of the loading chute 54 faces the dump truck 55;

[0088] The sampling device is the sampling device mentioned above, and the sampling device is connected to the funnel 53 to sample the material outputted from the feeder 52 to the funnel 53 , and the sampling and returning unit 3 of the sampling device returns the sampled material to the loading chute 54 .

[0089] Specifically, Figures 1 to 11 As shown, the dump truck 55 enters the bottom layer of the fast loading system and stops. The discharge port of the silo 51 is opened, and the silo 51 starts the feeder 52 to discharge the material. The bulk material is quantitatively and evenly fed into the hopper 53 through the feeder 52. The hopper 53 is connected to the loading chute 54 below, and the loading chute 54 guides the bulk material into the compartment of the dump truck 55 in a controllable manner.

[0090] When the bulk material is quickly loaded onto the truck, the sampling device performs sampling, crushing, cutting and storing the sample for sampling into the sample storage bottle 43, and at the same time returns the uncut material to the loading chute 54, and then the uncut material is loaded onto the truck.

[0091] The quick-loading bulk material system 5 of the embodiment of the present invention, by adopting a sampling device, is convenient for sampling the quick-loading bulk material system 5, reducing the sampling cost. In the process of loading materials, the sample is taken while the vehicle is being loaded, and the sampled materials are highly representative. There is no need to stop the loading to take samples separately, so that the goods can be loaded and shipped out of the factory efficiently. Therefore, no additional sampling time is added. The sampling position is as close to the vehicle as possible, which is most in line with the material quality when loading. The collected samples are directly packaged and stored, shortening the transportation and processing route, and reducing the impact of the transportation process on the quality. No manual sampling is required, reducing labor costs. The entire sampling process avoids manual operation and human interference, and runs fully automatically. The sampling device is integrated with the quick-loading bulk material system 5, and there is no need to invest in the construction of an independent sampling room, reducing costs. It can significantly improve the efficiency and accuracy of bulk material sampling, and the sampling results are excellently representative, providing reliable technical support for bulk commodity quality monitoring. At the same time, it greatly streamlines the construction land and saves precious land resources.

[0092] Further, the sample collection process of the embodiment of the present invention is described below. The quick-loading bulk material system 5 includes a silo 51, a feeder 52, a head hopper 53, a loading chute 54, and a dump truck 55. The silo 51 is provided with a discharge port.

[0093] The sampling unit includes a frame 11, an air lock 15, an air spring 16, a sampling head 13, a lifting frame 122, a lifting cylinder, a discharger 141, a translation guide rail 1433, a translation motor 1422, a fixed rack 1423, and a shield. The lifting frame 122 and the lifting cylinder are the lifting component 12, and the translation motor 1422 and the fixed rack 1423 are the first telescopic component 142.

[0094] The reduction system includes a reduction chute frame 31, a return conveyor 32, a cutter body 351, a bottom plate 353, a spring 352, a discharge block 354, a linear module, a sample storage chute, a sample storage bottle 43, and a sample collector 42.

[0095] Specific implementation:

[0096] The dump truck 55 enters the bottom layer of the quick-loading bulk material system 5 and stops. The discharge port is opened, and the feeder 52 is turned on. The bulk material is quantitatively and evenly fed into the hopper 53 through the feeder 52. The hopper 53 is connected to the loading chute 54 below, and the loading chute 54 can controllably guide the bulk material into the carriage.

[0097] After the material flow is stable, the sampling operation can be started. The frame 11 is fixed on the top of the funnel 53, the top surface of the funnel 53 is open, and an air lock valve 15 is provided, and the air lock valve 15 is supported by an air spring 16 to keep the opening normally closed to prevent dust from spilling out.

[0098] The lifting cylinder extends, driving the lifting frame 122 to descend. The sampling head 13 is connected to the bottom of the lifting frame 122. The sampling head 13 is the same width as the material flow, and the opening is larger than 3 times the nominal particle size of the material. The sampling head 13 is a "U"-shaped flat bottom structure with openings at the top and both ends to ensure that the entire cross-section of the material flow can be connected. When the sampling head 13 continues to descend until it is completely inserted into the material flow and the sampling head 13 is instantly filled, the lifting cylinder changes direction and rises.

[0099] When the lifting frame 122 and the sampling head 13 are lowered, they will contact the air lock door 15 and push it open. When the lifting frame 122 and the sampling head 13 are raised to the right position after sampling, the air lock door 15 is pushed back and closed by the air spring 16.

[0100] After the sampling head 13 completes the sample loading, the translation motor 1422 installed on the connecting frame 1421 is started, driving the gear to rotate, and through the engagement of the fixed rack 1423, the connecting frame 1421 is driven to move from the discharge end to the sampling end. The connecting frame 1421 is used to connect the discharger 141 and the translation motor 1422, and the discharger 141 moves to the sampling end. The discharger 141 is a "┌"-shaped structure, and the upper top plate covers the translation guide rail 1433 to ensure that the track of the discharger 141 in the left and right directions is straight.

[0101] After the sampling head 13 rises to its position, the lifting cylinder locks the position, the translation motor 1422 starts, and drives the unloader 141 to move from the sampling end to the unloading end. The unloader 141 pushes the material in the sampling head 13 to flow toward the unloading port. The top plate of the unloader 141 presses the sample material to prevent it from accumulating and overflowing the sampling head 13 during pushing. The unloader 141 pushes all the sample materials in the sampling head 13 into the sample outlet 111.

[0102] The sample material is evenly pushed out by the discharger 141 through the sample outlet 111 and enters the crushing unit 2, where the large particle size material is crushed into small particle size material, which is convenient for the next step of reduction operation. In actual application, a crusher can be selected according to the actual particle size.

[0103] Small-size samples are discharged from the crusher into the reduction chute. The side of the reduction chute is open for the cutter to enter and intercept the sample. The lower end of the reduction chute is connected to the return conveyor 32. The material not intercepted by the cutter falls into the return conveyor 32 as discarded material. The outlet of the return conveyor 32 is connected to the head funnel 53 of the loading system, and the discarded material returns to the loading material flow channel and falls back into the carriage. The cutter body 351 is a topless and bottomless square frame connected to the linear module. The cutter bottom plate 353 is movably connected to the cutter body 351 in the left and right directions. The spring 352 provides a normally closed torque so that the bottom plate 353 of the cutter is located at the lower end of the material receiving hole so that the material receiving hole 3511 is closed. The second telescopic component 34 can be a linear module, or a linear guide 1433. The linear module drives the cutter to move left and right, that is, the second telescopic component 34 drives the cutter to move left and right, and can enter the reduction chute to intercept samples. After the sample is intercepted, the linear module drives the cutter to move to the top of the sample discharge channel 312 and touches the discharge block 354. The discharge block 354 pushes the cutter bottom plate 353, so that the sample in the receiving hole 3511 falls into the sample discharge channel 312. When the cutter body 351 moves to the left and leaves the discharge block 354 again, the torque of the spring 352 closes the bottom of the cutter receiving hole 3511 again.

[0104] The sample collector 42 stores a number of sample bottles 43, each of which corresponds to a different customer or a different type of material, so as to facilitate the classification and storage of samples. The sample collector 42 can rotate and switch the sample bottles 43 to dock with the sample chute above, and the sample bottles 43 can receive and store the reduced samples. The above is a complete process of sampling, sample preparation, sample storage, and material return, and the same train can repeat the above process multiple times.
