[0024] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0025] In the description of the embodiments of this application, unless otherwise expressly specified and limited, technical terms such as "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.

[0026] One embodiment of this application provides a conveying system; please refer to [link / reference]. Figure 1 and Figure 2 The conveying system includes a material distribution device 10.

[0027] The material distribution device 10 includes multiple distributors 11, which are connected in sequence to form a material conveying path. Each distributor 11 has an inlet 11a, an outlet 11b, and a passage 11c that are connected to each other.

[0028] Along the material conveying path, between adjacent distributors 11, the feed port 11c of the upstream distributor 11 is connected to the feed port 11a of the downstream distributor 11.

[0029] Specifically, the distributor 11 refers to the component that realizes the distribution of materials. The distributor 11 introduces materials from the inlet 11a, conveys them through the outlet 11b to the component connected to the outlet 11b, or transmits the materials to the downstream distributor 11 through the feed port 11c, so as to realize the movement of materials on the material conveying path.

[0030] The number of feeders 11 is unlimited.

[0031] For example, the number of distributors 11 is two or more.

[0032] Feed inlet 11a refers to the inlet where the distributor 11 receives materials.

[0033] The discharge port 11b refers to the outlet where the distributor 11 outputs material to a designated location. The material is output through the discharge port 11b and transported to the processing equipment or storage device connected to the discharge port 11b.

[0034] The feed port 11c refers to the opening that connects adjacent feeders 11, allowing materials to be transferred between the feeders 11.

[0035] The feed inlet 11a, the discharge outlet 11b, and the feed passage 11c of the distributor 11 are interconnected, so that the material entering the distributor 11 from the feed inlet 11a can be output from the discharge outlet 11b alone, or from the feed passage 11c alone, or from both the discharge outlet 11b and the feed passage 11c at the same time.

[0036] The positions of the inlet 11a, outlet 11b, and feed inlet 11c are not limited.

[0037] For example, the inlet and outlet 11b are located on the same side of the distributor 11, while the inlet 11a and outlet 11c are located on opposite sides of the distributor 11. Thus, on the one hand, the fact that the inlet 11a and outlet 11b are on the same side allows material entering the distributor 11 to be quickly discharged from the outlet 11b, reducing the time material spends within the distributor 11 and improving material output efficiency. On the other hand, the fact that the inlet 11a and outlet 11c are on opposite sides of the distributor 11 facilitates material transport along the material conveying path.

[0038] The conveying system of this application embodiment includes a material distribution device 10, which includes multiple distributors 11. Each distributor 11 is sequentially connected to form a material conveying path. Each distributor 11 has an inlet 11a, an outlet 11b, and a feed inlet 11c that are interconnected. Along the material conveying path, between adjacent distributors 11, the feed inlet 11c of the upstream distributor 11 is connected to the inlet 11a of the downstream distributor 11. Therefore, on the one hand, the material conveying path formed by the sequential connection of multiple distributors 11 can distribute materials to different locations, meeting diverse production needs. Compared to the traditional single-distribution method, this greatly improves the efficiency and flexibility of material distribution. On the other hand, the connection between adjacent distributors 11 through the feed inlet 11a and the feed inlet 11c ensures continuous material flow throughout the entire conveying system, preventing material interruptions or accumulation, ensuring the stability of the production process, and reducing production stoppages caused by material conveying problems.

[0039] In one embodiment, please refer to Figure 1 The conveying system also includes a collection device 20 and a feeding device 30. The collection device 20 is connected to at least one discharge port 11b, and the feeding device 30 is connected to at least one inlet 11a of the distributor 11 located at the beginning of the material conveying path. The collection device 20 includes a sensor and a storage bin 23. The sensor is installed in the storage bin 23, and at least one of the distributor 10 and the feeding device 30 is connected to the sensor signal. This achieves automated material replenishment and distribution, reduces manual intervention, and keeps the material supply and collection of the entire conveying system in a balanced state, thereby improving the conveying efficiency of the system.

[0040] Specifically, the collecting device 20 refers to a component that is connected to the discharge port 11b to collect the material output from the discharge port 11b.

[0041] The feeding device 30 refers to the component that transports materials to the distributing device 10, providing the initial material source for the entire conveying system.

[0042] The fact that the collecting device 20 is connected to at least one discharge port 11b means that the collecting device 20 may be connected to only one discharge port 11b of the distributor 11, or it may be connected to the discharge ports 11b of multiple distributors 11.

[0043] The feeding device 30 being connected at least to the inlet 11a of the distributor 11 at the beginning of the material conveying path means that the feeding device 30 can be connected only to the inlet 11a of the distributor 11 at the beginning of the material conveying path. Material enters through the inlet 11a of the distributor 11 at the beginning of the material conveying path and is output through the outlet 11c to the downstream distributor 11. Alternatively, the feeding device 30 can be connected to the inlets 11a of multiple distributors 11 to selectively feed material into different distributors 11.

[0044] The storage bin 23 refers to the component that is connected to the discharge port 11b to collect the material output by the distributor 11.

[0045] The sensor refers to a component located inside the storage silo 23, used to monitor the state of the materials inside the storage silo 23. Based on information such as the quantity, height, or presence of abnormalities of the materials inside the storage silo 23, the sensor feeds back this information as a signal to the material distribution device 10 and / or the feeding device 30 connected to it.

[0046] The location of the sensor within the storage bin 23 is not limited.

[0047] For example, the sensor is located on top of the storage bin 23.

[0048] For example, the sensor is located at the bottom of the storage bin 23.

[0049] Of course, the sensor can also be located in the middle area of ​​the storage bin 23.

[0050] The connection of at least one of the dispensing device 10 and the feeding device 30 to the sensor signal means that only the dispensing device 10 can be connected to the sensor signal, and the sensor controls the working state of the dispensing device 10 according to the material state in the storage hopper 23. Alternatively, only the feeding device 30 can be connected to the sensor signal, and the sensor controls the working state of the feeding device 30 according to the material state in the storage hopper 23. Furthermore, both the dispensing device 10 and the feeding device 30 can be connected to the sensor signal simultaneously, and the sensor controls the working state of both the dispensing device 10 and the feeding device 30 according to the material state in the storage hopper 23.

[0051] In one embodiment, please refer to Figure 1 The distributor 11 includes a control valve 111. At least one of the discharge port 11b and the feed port 11c is equipped with the control valve 111. A sensor is signal-connected to the control valve 111 to control the opening and closing of the discharge port 11b and / or the feed port 11c. Thus, automatic control of the material flow within the distributor 11 is achieved through the signal connection between the sensor and the control valve 111, reducing manual operation.

[0052] Specifically, control valve 111 refers to a component used to control the flow of materials.

[0053] The fact that at least one of the discharge port 11b and the feed port 11c is equipped with a control valve 111 means that: Control valve 111 can be installed only at the discharge port 11b, and the opening and closing of the discharge port 11b can be controlled by control valve 111. Alternatively, control valve 111 can be installed only at the feed port 11c, and the opening and closing of the feed port 11c can be controlled by control valve 111. Furthermore, control valve 111 can be installed at both the discharge port 11b and the feed port 11c, and the opening and closing of both the discharge port 11b and the feed port 11c can be controlled by control valve 111.

[0054] In one embodiment, please refer to Figure 1 The sensor includes a first level sensor 21 and a second level sensor 22. The first level sensor 21 is located at the bottom of the storage silo 23, and the second level sensor 22 is located at the top of the storage silo 23. Therefore, by installing the first level sensor 21 and the second level sensor 22 at the bottom and top of the storage silo 23 respectively, the storage status of the material in the storage silo 23 can be monitored in real time, effectively preventing material shortages or overflows, achieving refined management of the material in the storage silo 23, and improving material utilization.

[0055] Specifically, the first level sensor 21 is installed at the bottom of the storage bin 23 to monitor the lowest material level in the storage bin 23. It can provide real-time feedback on whether the material in the storage bin 23 is at a low level.

[0056] The second level sensor 22 is installed on top of the storage silo 23 to monitor the highest material level in the storage silo 23. It can provide real-time feedback on whether the storage silo 23 is full.

[0057] It should be noted that the bottom and top of the storage bin 23 are not bottom and top in the strict sense, but rather preset positions of the storage bin 23 in the state of being short of material and full of material, respectively, according to actual needs.

[0058] The structure of the first level sensor 21 is not limited.

[0059] For example, the first level sensor 21 is a rotary paddle level sensor.

[0060] The structure of the second level sensor 22 is not limited.

[0061] For example, the second level sensor 22 is a rotary paddle level sensor.

[0062] For example, both the first level sensor 21 and the second level sensor 22 are signal-connected to the feeding device 30. When the storage hopper 23 is full, the second level sensor 22 detects the presence of material and sends a signal to the feeding device 30, at which point the feeding device 30 stops feeding material. When the storage hopper 23 is low on material, the first level sensor 21 does not detect the presence of material and sends a signal to the feeding device 30, at which point the feeding device 30 continues to feed material into the storage hopper 23.

[0063] For example, both the first level sensor 21 and the second level sensor 22 are signal-connected to the material distribution device 10. When the storage silo 23 is full, the second level sensor 22 detects the presence of material and sends a signal to the material distributor 11 connected to the storage silo 23. At this time, the material distributor 11 stops feeding material into the storage silo 23. When the storage silo 23 is low on material, the first level sensor 21 does not detect the presence of material and sends a signal to the material distributor 11 connected to the storage silo 23. At this time, the material distributor 11 continues to feed material into the storage silo 23.

[0064] It is understandable that the first level sensor 21 and the second level sensor 22 can have other signal connection methods with the feeding device 30 and the distributing device 10. As long as the following conditions are met: when the first level sensor 21 does not detect material in the storage bin 23, that is, when the storage bin 23 is low on material, the conveying system can deliver material into the storage bin 23; when the second level sensor 22 detects material, that is, when the storage bin 23 is full, the conveying system can stop delivering material into the storage bin 23.

[0065] In one embodiment, please refer to Figure 1 The feeding device 30 also includes a cold hopper 34, a first magnetic separator 32, a crusher 31, and a second magnetic separator 33. The two ends of the crusher 31 are connected to the cold hopper 34 and the feeding device 30, respectively. The first magnetic separator 32 is positioned between the cold hopper 34 and the crusher 31, and the second magnetic separator 33 is positioned between the crusher 31 and the feeding device 30. Thus, on the one hand, the crusher 31 can adjust the particle size of the material, making it more suitable for the production process. On the other hand, the two magnetic separations performed by the first magnetic separator 32 and the second magnetic separator 33 effectively remove magnetic impurities from the material, improving the purity of the material entering the distribution device 10, the collection device 20, and subsequent production stages, thereby improving product quality.

[0066] Specifically, crusher 31 refers to equipment that crushes larger particles of material into smaller particles.

[0067] The first magnetic separator 32 and the second magnetic separator 33 refer to devices that use a magnetic field to adsorb magnetic materials onto the magnetic poles of the magnetic separator, while other non-magnetic materials pass through smoothly, thereby achieving the purpose of removing magnetic impurities and improving the purity of the materials.

[0068] The first magnetic separator 32 is positioned between the cold hopper 34 and the crusher 31. During the process of conveying the material from the cold hopper 34 to the crusher 31 via a conveyor belt, magnetic impurities in the material are separated by the magnetic field of the first magnetic separator 32, resulting in preliminarily purified material. Next, the preliminarily purified material enters the crusher 31, where it is crushed to reduce the particle size to a suitable range. The crushed material exits the crusher 31 and is conveyed to the feeding device via a conveyor belt. During this transport, a second magnetic separator 33, positioned between the crusher 31 and the feeding device 30, performs another magnetic separation to further remove magnetic impurities.

[0069] The structure of the crusher 31 is not limited.

[0070] For example, the crusher is a frequency converter-controlled crusher 31. This allows for flexible adjustment of the crushing speed and force according to the characteristics of the material and production needs, improving the crushing effect and processing efficiency.

[0071] In one embodiment, please refer to Figure 1 The crusher 31 includes a current sensor, which monitors the current within the crusher 31 to control the start and stop of the cold hopper 34 based on a preset current. Therefore, by monitoring the current in the crusher 31 and controlling the start and stop of the cold hopper 34 through the current sensor, material conveying efficiency is improved, damage to the crusher 31 due to overload is effectively prevented, the service life of the crusher 31 is extended, and equipment maintenance costs and replacement frequency are reduced.

[0072] Specifically, the cold hopper 34 refers to the equipment used to convey materials to the crusher 31.

[0073] A current sensor is used to monitor the current in the crusher 31. When the current reaches the preset upper limit, the cold hopper 34 stops feeding material into the crusher 31. When the current reaches the preset lower limit, the cold hopper 34 starts feeding material into the crusher 31 again.

[0074] In one embodiment, please refer to Figure 1 The material handling device also includes a main hopper 35, a third level sensor 36, and a fourth level sensor 37. The main hopper 35 is connected to the distribution device 10 and the crusher 31, respectively. The third level sensor 36 and the fourth level sensor 37 are connected to the cold hopper 34 via signals. The third level sensor 36 is located at the bottom of the main hopper 35, and the fourth level sensor 37 is located at the top of the main hopper 35. Therefore, by installing the third level sensor 36 and the fourth level sensor 37 at the bottom and top of the main hopper 35 respectively, the storage status of the material in the main hopper 35 can be monitored in real time, effectively preventing material shortages or overflows, achieving refined management of the material in the main hopper 35, and improving material utilization.

[0075] Specifically, the main hopper 35 refers to the equipment that receives the material processed by the second magnetic separator 33 and supplies the material to the material distribution device 10.

[0076] The structural type of the total hopper 35 is not limited.

[0077] For example, the total hopper 35 is a frequency converter controlled hopper.

[0078] The third level sensor 36 is installed at the bottom of the main hopper 35 to monitor the lowest material level in the main hopper 35. It can provide real-time feedback on whether the material in the main hopper 35 is at a low level.

[0079] The fourth level sensor 37 is installed on top of the main hopper 35 to monitor the highest material level in the main hopper 35. It can provide real-time feedback on whether the main hopper 35 is full.

[0080] It should be noted that the bottom and top of the main hopper 35 are not exactly bottom and top in the strict sense, but rather preset positions of the main hopper 35 in the state of being short of material and full of material, respectively, according to actual needs.

[0081] The structure of the third level sensor 36 is not limited.

[0082] For example, the third level sensor 36 is a rotary paddle level sensor.

[0083] The structure of the fourth level sensor 37 is not limited.

[0084] For example, the fourth level sensor 37 is a rotary paddle level sensor.

[0085] For example, both the third level sensor 36 and the fourth level sensor 37 are signal-connected to the cold hopper 34. When the main hopper 35 is full, the fourth level sensor 37 detects the presence of material and sends a signal to the cold hopper 34, at which point the cold hopper 34 stops conveying material. When the main hopper 35 is low on material, the third level sensor 36 does not detect the presence of material and sends a signal to the cold hopper 34, at which point the cold hopper 34 continues to convey material into the main hopper 35.

[0086] In one embodiment, the collecting device 20 has a discharge port, and the conveying system includes a conveying channel, with the discharge port communicating with the conveying channel. Therefore, by providing a conveying channel at the discharge port, materials can be promptly conveyed to subsequent production equipment or storage areas, thereby effectively improving material flow efficiency. Specifically, the discharge port refers to the opening through which material exits from the collecting device 20.

[0087] A conveyor channel refers to the channel through which objects are transported from the discharge port to subsequent production equipment or storage areas.

[0088] The shape of the conveyor channel is not limited.

[0089] For example, the conveying channel is a spiral conveyor. This improves the conveying efficiency of materials output from the collection device 20, meeting the requirements for material conveying speed.

[0090] In one specific embodiment, the feeding device 30 includes an elevator 38, which is connected to both the main hopper 35 and the distributor 11. This enables material to be conveyed between different heights, improving the conveying efficiency of material from the main hopper 35 to the distributor 11.

[0091] In one specific embodiment, the distributors 11 are connected to each other via a distribution belt 12.

[0092] In one embodiment, along the material conveying path, multiple distributors 11 include a first distributor, a second distributor, a third distributor, and a fourth distributor. The collecting device 20 includes a first storage bin, a second storage bin, a third storage bin, and a fourth storage bin. Each distributor 11 is connected to each storage bin 23 in a one-to-one correspondence. The material is conveyed to the first distributor connected to the elevator 38 via the elevator 38. When the discharge port 11b of the first distributor is opened, the material falls into the first storage bin. When the discharge port 11b of the first distributor is closed, the first distribution bin is closed, and the material is output to the distribution belt 12 through the material passage port 11c of the first distributor and transferred to the second distributor.

[0093] When the discharge port 11b of the second distributor opens, the material falls into the second storage bin. When the discharge port 11b of the second distributor closes, the second distribution bin is closed, and the material is output through the feed port 11c of the second distributor to the distribution belt 12 and then transferred to the third distributor.

[0094] When the discharge port 11b of the third distributor opens, the material falls into the third storage bin. When the discharge port 11b of the third distributor closes, the third distribution bin is closed, and the material is output through the feed port 11c of the third distributor to the distribution belt 12 and then transferred to the fourth distributor.

[0095] When the discharge port 11b of the fourth distributor opens, the material falls into the fourth storage bin. When the first, second, third, and fourth storage bins are all full, the conveying system is shut down to stop the material conveying.

[0096] It should be noted that the bottom and top of the first, second, third, and fourth storage silos are each equipped with a first level sensor 21 and a second level sensor 22. When the first, second, third, and fourth storage silos are full, the discharge port 11b of the corresponding feeder 11 is closed, and an alarm is triggered indicating that the storage silo 23 is full and the next storage silo 23 needs to be conveyed. When the first, second, third, and fourth storage silos are all full, the conveying system is shut down to stop material conveying.
