[0040] See also Figure 1 and Figure 3 , the present application embodiment provides a wind selection device 100, used in a screening system 200.

[0041] See also Figure 1 and Figure 2 The screening system 200 includes a first feeding device 400, an air selection device 100 and a vibration sorting device 300. The air selection device 100 includes an air selection channel 10, a feed port 11 connected to the air selection channel 10, and at least one discharge port. The feed port 11 is connected to the first feeding device 400, and one of all the discharge ports is connected to the vibration sorting device 300.

[0042] The first feeding device 400 is used to convey the raw material through the feed port 11 to the air separation channel 10 at a preset rate. The air separation device 100 is used to perform a first screening operation on the raw material in the air separation channel 10 and separate the screened material from the raw material, and guide the screened material to the vibration sorting device 300 through a discharge port connected to the vibration sorting device 300. The vibration sorting device 300 is used to perform a second screening operation on the screened material and separate the target material from the screened material.

[0043] During the operation of the screening system 200, the raw material is first placed on the first feeding device 400, and the raw material is transported to the air separation device 100 at a preset rate through the first feeding device 400. The raw material enters the air separation channel 10 through the feed port 11, and the raw material is subjected to a first screening operation in the air separation channel 10 to separate the screened material from the raw material. The screened material is then directed to the vibration separation device 300 through the discharge port connected to the vibration separation device 300, and finally the screened material is subjected to a second screening operation through the vibration separation device 300 to separate the target material from the screened material.

[0044] It can be understood that the preset rate means that when the first feeding device 400 conveys the raw material to the air separation device 100 at a preset rate, a certain amount of raw material can be fed from the feed port 11 into the air separation channel 10 within a unit time, so as to meet the raw material required for the first screening operation within a unit time, thereby ensuring the working efficiency of the screening system 200.

[0045] It should be noted that the preset rate is obtained through experimental testing, and the parameters, steps, etc. related to the experimental testing of the preset rate are conventional techniques of those skilled in the art and will not be elaborated here.

[0046] In the embodiment of the present application, the screening system 200 is used in the technical field of waste cigarette recycling, and the present application is written with the screening system 200 being used in the technical field of waste cigarette recycling as an embodiment. Correspondingly, the screening system 200 is used to perform the first screening operation and the second screening operation on the waste cigarette in sequence, so as to screen out cigarettes that meet the recycling needs from the waste cigarettes, so as to realize the recycling of waste cigarettes. Among them, the raw material corresponds to the waste cigarette raw material, and the waste cigarette raw material contains foreign matter, paper pieces, tobacco shreds, standard cigarettes and abnormal cigarettes. The abnormal cigarettes correspond to double cigarettes, run-off cigarettes and bonded cigarettes, etc. The screening material is the standard cigarettes and abnormal cigarettes screened from the waste cigarette raw material, and the target material is the standard cigarettes screened from the screening material. The standard cigarettes are residual cigarettes and short cigarettes.

[0047] It is understandable that the specific definition of standard cigarettes is not limited, standard cigarettes need to meet recycling conditions, and the recycling conditions are determined according to actual needs.

[0048] It is understandable that the application field of the screening system 200 is not limited to this. In other embodiments, the raw material, the screening material and the target material may also correspond to other materials.

[0049] In the present application, the screening system 200 performs multiple screening operations on the waste smoke raw materials containing various substances through the air separation device 100 and the vibration sorting device 300, and can separate the target materials that meet the user's needs from the waste smoke raw materials, thereby omitting the manual screening steps required in the prior art, which is conducive to saving costs, improving screening efficiency, and reducing the work pressure of subsequent processing steps.

[0050] See also Figure 1 and Figure 3 The air selection device 100 includes at least two discharge ports, and the air selection channel 10 extends longitudinally along the first direction; all the discharge ports are located on the same side of the air selection channel 10 and are arranged in sequence along the first direction; the feed port 11 is arranged on the other side of the air selection channel 10, and all the discharge ports are located below the feed port 11 along the gravity direction intersecting the first direction;

[0051] In which, when the raw material enters the air separation channel 10 from the feed port 11 and falls in the direction of gravity, the screened material in the raw material moves along the first direction to the discharge port connected to the vibration sorting device 300 driven by the air separation airflow in the air separation channel 10.

[0052] It can be understood that after the raw material enters the air separation channel 10 from the feed port 11, it will fall in the direction of gravity in the air separation channel 10 due to the action of gravity. At the same time, there is an air separation airflow flowing along the first direction in the air separation channel 10. In this way, the screened material in the raw material will move along a parabolic trajectory to the discharge port connected to the vibration sorting device 300 under the dual action of the air separation airflow and gravity, thereby completing the first screening operation of the raw material; the other parts of the raw material will be discharged from other discharge ports.

[0053] In the present application, the waste smoke raw material containing various substances is screened by the air separation device 100 to achieve preliminary screening of the waste smoke raw material, so as to remove impurities in the waste smoke raw material and reduce the work pressure of subsequent processing steps.

[0054] In the present application, the raw material is waste tobacco raw material, and includes foreign matter, paper pieces, tobacco, standard cigarettes and abnormal cigarettes, among which foreign matter is objects with higher density such as stones and wood blocks. Thus, in the waste tobacco raw material, the density of foreign matter>the density of standard cigarettes and abnormal cigarettes>the density of paper pieces and tobacco, and correspondingly, the weight of foreign matter>the weight of standard cigarettes and abnormal cigarettes>the weight of paper pieces and tobacco.

[0055] Based on this, it is defined that the air selection airflow flowing along the first direction in the air selection channel 10 has a preset wind speed. It can be understood that, according to actual needs, the air selection airflow can correspondingly drive the paper pieces and tobacco shreds, and / or standard cigarettes and abnormal cigarettes, and / or foreign objects in the waste tobacco raw materials to move at the preset wind speed, and when the paper pieces and tobacco shreds, standard cigarettes and abnormal cigarettes, and foreign objects all fall the same distance in the direction of gravity in the air selection channel 10, the distance that the paper pieces and tobacco shreds move along the first direction under the action of the air selection airflow>the distance that the standard cigarettes and abnormal cigarettes move along the first direction under the action of the air selection airflow>the distance that the foreign objects move along the first direction under the action of the air selection airflow. In this way, different discharge ports can be opened according to the different movement trajectories of the paper pieces and tobacco shreds, standard cigarettes and abnormal cigarettes, and foreign objects to achieve the separation of paper pieces and tobacco shreds, standard cigarettes and abnormal cigarettes, and foreign objects.

[0056] The specific number of discharge ports is not limited. Figure 1 and Figure 3 The air separation device 100 includes a first discharge port 12, a second discharge port 13 and a third discharge port 14 which are sequentially arranged along a first direction, and the first discharge port 12 is connected to the feed port 11 along the gravity direction.

[0057] Among them, the air selection airflow drives the material with lower density than the screened material in the raw material to move along the first direction to the third discharge port 14, and the third discharge port 14 is used to discharge the material with lower density than the screened material, and the first discharge port 12 is used to discharge the material with higher density than the screened material in the raw material.

[0058] It can be understood that the air flow can correspondingly drive the paper pieces and tobacco shreds, and standard cigarettes and abnormal cigarettes in the waste tobacco raw materials to move at a preset wind speed. In this way, after the raw materials enter the air selection channel 10 from the feed port 11, the foreign matter will be directly affected by gravity and fall in the direction of gravity in the air selection channel 10, and be discharged from the first discharge port 12; the standard cigarettes and abnormal cigarettes will move along a parabolic trajectory to the second discharge port 13 under the dual action of the air selection air flow and gravity, and be discharged from the second discharge port 13; the paper pieces and tobacco shreds will move along a parabolic trajectory to the third discharge port 14 under the dual action of the air selection air flow and gravity, and be discharged from the third discharge port 14.

[0059] It should be noted that the specific value range of the preset wind speed when the airflow drives the paper pieces and tobacco in the waste tobacco raw materials, and the standard cigarettes and abnormal cigarettes to move is not limited. The specific value range of the preset wind speed is obtained through experimental testing. The parameters, steps, etc. related to the experimental testing of the specific value range of the preset wind speed are conventional techniques of those skilled in the art and are not elaborated here.

[0060] For some examples, see Figure 1 and Figure 3The specific value range of the preset wind speed V1 is: 10m / s (millimeter / second, meters per second) ≤ V1 ≤ 15m / s.

[0061] For some examples, see Figure 1 and Figure 3 The air selection device 100 also includes three outlets 16, which are all connected to the air selection body and surround the outside of the first outlet 12, the second outlet 13 and the third outlet 14 respectively, so as to form an outlet channel connected to the corresponding outlets. It can be understood that, taking paper pieces and tobacco as an example, due to the light density and weight of paper pieces and tobacco, the movement trajectory and distribution of paper pieces and tobacco are relatively scattered under the action of the air selection airflow. After the paper pieces and tobacco move to the third outlet 14, they will continue to fall into the outlet channel under the action of gravity. In this way, the paper pieces and tobacco in the outlet channel can be gathered and directed under the action of the outlet 16, so as to facilitate collection and facilitate further use according to actual needs.

[0062] For some examples, see Figure 1 and Figure 3 The opening position of the third discharge port 14 is higher than the opening position of the first discharge port 12 in the direction opposite to gravity, the second discharge port 13 is connected between the first discharge port 12 and the third discharge port 14, and the end of the second discharge port 13 close to the third discharge port 14 is inclined toward the end close to the first discharge port 12.

[0063] It can be understood that when paper pieces and tobacco, standard cigarettes and abnormal cigarettes, and foreign objects all fall the same distance in the direction of gravity in the air selection channel 10, the distance that paper pieces and tobacco move along the first direction under the action of the air selection airflow is the largest.

[0064] In the present application, the third discharge port 14, the second discharge port 13 and the first discharge port 12 are arranged in sequence along the gravity direction, so that the paper pieces and tobacco shreds can be preferentially discharged from the third discharge port 14 to prevent the paper pieces and tobacco shreds from falling into the second discharge port 13 and mixing with the standard cigarettes and abnormal cigarettes, thereby ensuring the screening effect. Correspondingly, the second discharge port 13 is connected between the first discharge port 12 and the third discharge port 14, which can ensure the maximum opening range, thereby better collecting standard cigarettes and abnormal cigarettes to ensure the screening effect.

[0065] For some examples, see Figure 1 and Figure 3 , the air selection channel 10 extends in an arc shape.

[0066] It can be understood that the air selection airflow will be guided by the inner wall of the air selection channel 10 and flow in an arc shape during the process of flowing along the first direction. In this way, the paper pieces and tobacco will also move synchronously with the air selection airflow, so that the paper pieces and tobacco can be further separated from the standard cigarettes and abnormal cigarettes, and the paper pieces and tobacco can be preferentially discharged from the third discharge port 14, thereby ensuring the screening effect.

[0067] For some examples, see Figure 1 and Figure 3 The air separation device 100 also includes two shielding members 17. All of the shielding members 17 are rotatably connected to the air separation body and are all located in the air separation channel 10. The two shielding members 17 are respectively arranged between the first discharge port 12 and the second discharge port 13, and between the second discharge port 13 and the third discharge port 14.

[0068] It can be understood that the shielding member 17 can be rotated according to actual needs to correspondingly adjust the height relationship between the first discharge port 12, the second discharge port 13 and the third discharge port 14, and synchronously adjust the opening size of the first discharge port 12, the second discharge port 13 and the third discharge port 14, so as to ensure that each discharge port can better collect the corresponding material to ensure the screening effect.

[0069] The specific style of the shielding member 17 is not limited. In some embodiments, see Figure 1 and Figure 3 Each shielding member 17 includes a rotating portion 171 and a shielding portion 172. The opposite sides of the rotating portion 171 are respectively connected to the inner wall of the air selection channel 10 and one end of the shielding portion 172. The rotating portion 171 can drive the shielding portion 172 to rotate in a controlled manner.

[0070] In the embodiment of the present application, the shielding portion 172 is a plate-like structure that is roughly rectangular as a whole. One end of the shielding portion 172 is rotatably connected to the rotating portion 171 and can rotate relative to the inner wall of the air selection channel 10. The other end of the shielding portion 172 extends away from the inner wall of the air selection channel 10, and in the process of the shielding portion 172 rotating relative to the inner wall of the air selection channel 10, the height relationship between the first discharge port 12, the second discharge port 13 and the third discharge port 14 can be correspondingly adjusted, and the opening size of the first discharge port 12, the second discharge port 13 and the third discharge port 14 can be synchronously adjusted, thereby ensuring that each discharge port can better collect the corresponding material to ensure the screening effect.

[0071] For some examples, see Figure 1 and Figure 3 The air separation device 100 further includes an introduction portion 18, which is connected to the air separation body and surrounds the outer side of the feed port 11 to form a feed channel connected to the feed port 11, and a communication port 182 connected to the feed channel is opened on the introduction portion 18;

[0072] Among them, the connecting port 182 and the feed port 11 are spaced apart and staggered along the gravity direction, and the inner wall of one side of the feed channel opposite to the opening of the connecting port 182 is constructed to form an inclined surface 181, which is inclined downward along the gravity direction toward the feed port 11.

[0073] In the present application, the feed channel is connected between the first feeding device 400 and the feed port 11, and the connecting port 182 is connected to the first feeding device 400. After the first feeding device 400 conveys the raw material to the connecting port 182, the raw material falls from the connecting port 182 to the inclined surface 181 of the feed channel under the action of gravity, and then the raw material moves to the feed port 11 under the guidance of the inclined surface 181, and then enters the air selection channel 10 to complete the first screening operation.

[0074] For some examples, see Figure 1 and Figure 3 The air selection device 100 also includes an air outlet member 15, which is arranged in the air selection channel 10 and is located at the head end of the air selection airflow flowing along the first direction, and is used to provide the air selection channel 10 with an airflow flowing along the first direction.

[0075] For some examples, see Figure 1 and Figure 3 The third discharge port 14 is located in the air selection channel 10 and at the end of the air selection airflow flowing in the first direction. The air selection device 100 also includes a negative pressure component 600, which is connected to the third discharge port 14 and is used to absorb the airflow in the air selection channel 10.

[0076] It can be understood that the air selection airflow blown out from the air outlet 15 can pass through the air selection channel 10 and the negative pressure assembly 600 in sequence to form a complete airflow channel, and is absorbed by the negative pressure assembly 600, so that the air selection airflow can flow smoothly. At the same time, the air selection airflow can directly drive the paper pieces and tobacco into the negative pressure assembly 600 to achieve the collection of paper pieces and tobacco.

[0077] The specific type of the negative pressure component 600 is not limited and can be configured as needed to meet different requirements. In some embodiments, the negative pressure component 600 is a dust collector.

[0078] For some examples, see Figure 4 and Figure 7The vibration sorting device 300 includes a first vibration sorting element 30, a second vibration sorting element 31 and a third vibration sorting element 32. The first vibration sorting element 30 is used to separate sub-materials not larger than a preset length from the screened material, and transfer the sub-materials to the second vibration sorting element 31; the second vibration sorting element 31 is used to separate target materials not larger than a first preset diameter from the sub-materials, and transfer the target materials to the third vibration sorting element 32; the third vibration sorting element 32 is used to transfer the target materials to other equipment.

[0079] It can be understood that the screening material is the standard cigarettes and abnormal cigarettes screened from the waste cigarette raw materials, and the abnormal cigarettes correspond to double cigarettes, runaway cigarettes and bonded cigarettes, etc., then the sub-material is the standard cigarettes and bonded cigarettes left after the double cigarettes and runaway cigarettes are separated from the screening material, and the corresponding target material is the standard cigarettes after the bonded cigarettes are separated from the sub-material. In this application, standard cigarettes correspond to residual cigarettes and short cigarettes.

[0080] In the present application, the vibration sorting device 300 can screen the screened material through the first vibration sorting component 30 and the second vibration sorting component 31 respectively, so as to separate the target material that meets the user's needs from the screened material, thereby omitting the manual screening step required in the prior art, which is beneficial to saving costs, improving screening efficiency, and reducing the work pressure of subsequent processing steps.

[0081] For some examples, see Figure 4 and Figure 7 The first vibration sorting member 30 is arranged above the second vibration sorting member 31 at intervals along the gravity direction. The first vibration sorting member 30 is a plate body. The plate body is provided with a plurality of groups of first screening units 301 at intervals along its length direction. Each group of first screening units 301 includes a plurality of first screening holes 302 arranged side by side along the width direction of the plate body. All the first screening holes 302 penetrate the plate body.

[0082] The first vibrating sorting element 30 is used to controllably drive the screening material thereon to vibrate and move forward along its own length direction so that the sub-materials fall from the first screening holes 302 onto the second vibrating sorting element 31 .

[0083] It can be understood that the screened material on the first vibrating separator 30 vibrates driven by the first vibrating separator 30 , and during the vibration process, the sub-material in the screened material can escape from the first screening hole 302 and fall onto the second vibrating separator 31 .

[0084] For some examples, see Figure 4 and Figure 5The second first screening hole 302 has a preset diameter D2, and the second preset diameter D2 needs to meet the condition: 40mm≤D2≤60mm, and the preset length L1 needs to meet the condition: 80mm≤L1≤85mm.

[0085] It can be understood that the screening materials include standard cigarettes and abnormal cigarettes, and the abnormal cigarettes correspond to double cigarettes, running cigarettes and bonded cigarettes, etc., among which the length of standard cigarettes and bonded cigarettes meets the preset length L1, while the length of double cigarettes and running cigarettes is greater than the preset length L1.

[0086] In the present application, the first screening hole 302 has a preset diameter, so that sub-materials not longer than the preset length can pass through the first screening hole 302 and fall onto the second vibrating sorting element 31, and double cigarettes and running cigarettes longer than the preset length cannot fall out of the first screening hole 302, thereby achieving screening processing of the screening material to separate the sub-materials.

[0087] It should be noted that the specific value of the preset diameter needs to ensure that standard cigarettes and glued cigarettes that are no longer than the preset length fall out through the first screening hole 302, and also needs to ensure that double cigarettes and runaway cigarettes that are longer than the preset length cannot fall out from the first screening hole 302. The specific value of the preset diameter is obtained through experimental testing, and the parameters, steps, etc. related to the experimental testing of the specific value of the preset diameter are conventional techniques of those skilled in the art, and will not be elaborated here.

[0088] For some examples, see Figure 4 and Figure 7 The vibration sorting device 300 also includes an adjustment component 33, which includes a conveying member 332 and a plurality of cross bars 331. The conveying member 332 is located upstream of the conveying direction of the first vibration sorting member 30, and the conveying member 332 is used to receive the screened material discharged from the feed port 11, and convey the screened material to the first vibration sorting member 30 along the conveying direction of the first vibration sorting member 30; the cross bars 331 extend along the vibration direction of the first vibration sorting member 30, and are arranged on the conveying member 332 at intervals along the conveying direction of the first vibration sorting member 30. The cross bars 331 are used to guide the screened material to be parallel to itself during the process of the conveying member 332 conveying the screened material.

[0089] It can be understood that the conveying member 332 is connected between the air separation device 100 and the first vibrating separation member 30. The conveying member 332 is used to convey the screened material separated from the air separation device 100 to the first vibrating separation member 30, and in the process of conveying the screened material by the conveying member 332, the screened material will pass through a number of cross bars 331 in sequence. The cross bars 331 can guide the screened material to be parallel to itself, that is, the length direction of all cigarettes in the screened material is parallel to the width direction of the first vibrating separation member 30. In this way, after the screened material is conveyed to the first vibrating separation member 30, it vibrates under the drive of the first vibrating separation member 30 and can fall out of the first screening hole 302 more smoothly, so as to improve the screening efficiency.

[0090] For some examples, see Figure 4 and Figure 7 The second vibration sorting member 31 is arranged above the third vibration sorting member 32 at intervals along the gravity direction. The second vibration sorting member 31 is a plate body. The plate body is provided with a plurality of groups of second screening units 311 at intervals along its length direction. Each group of second screening units 311 includes a plurality of second screening holes 312 arranged side by side along the width direction of the plate body. All the second screening holes 312 penetrate the plate body.

[0091] The second vibrating sorting element 31 is used to controllably drive the sub-material located thereon to vibrate and move forward along its own length direction, so that the target material falls from the second screening hole 312 onto the third vibrating sorting element 32 .

[0092] It can be understood that the sub-material located on the second vibrating sorting element 31 vibrates under the drive of the second vibrating sorting element 31 , and during the vibration process, the target material in the sub-material can escape from the second screening hole 312 and fall onto the third vibrating sorting element 32 .

[0093] For some examples, see Figure 4 and Figure 7 Each group of second screening units 311 also includes a plurality of guide members 313. All the guide members 313 in each group of second screening units 311 extend along the length direction of the second vibrating sorting member 31, and are arranged at intervals along the width direction of the second vibrating sorting member 31. A preset number of second screening holes 312 are provided between each two adjacent guide members 313. The guide members 313 are used to guide the sub-material to be parallel to themselves during the process of the second vibrating sorting member 31 vibrating the sub-material.

[0094] It can be understood that when the sub-material vibrates under the drive of the second vibrating sorting component 31, the sub-material will contact the guide member 313, and the guide member 313 can guide the sub-material to be parallel to itself, that is, the length direction of all cigarettes in the sub-material is parallel to the length direction of the second vibrating sorting component 31. In this way, the screened material can fall out of the second screening hole 312 more smoothly to improve the screening efficiency.

[0095] For some examples, see Figure 4 and Figure 6 All the second screening holes 312 are U-shaped holes, and all the second screening holes 312 extend along the length direction of the second vibration sorting component 31 and have a preset size, the preset size needs to meet the condition: ≥L1+30mm, the first preset diameter needs to meet the condition: 7mm≤≤8mm, all the second screening holes 312 have a third preset diameter, the third preset diameter needs to meet the condition: ≥3×.

[0096] It is understandable that the sub-material includes standard cigarettes and adhesive cigarettes, wherein the lengths of the standard cigarettes and the adhesive cigarettes satisfy the preset length L1, the diameters of the standard cigarettes satisfy the first preset diameter, and the diameter of the adhesive cigarettes is greater than the first preset diameter.

[0097] In the present application, the second screening hole 312 has a preset size and a third preset diameter, which can allow the target material not larger than the first preset diameter to fall through the second screening hole 312 onto the third vibrating sorting element 32, and the adhesive smoke and the like larger than the first preset diameter cannot fall out of the second screening hole 312, thereby realizing the screening process of the sub-materials to separate the target material.

[0098] It should be noted that the specific values ​​of the preset size and the third preset diameter need to ensure that the target material not larger than the first preset diameter falls out through the second sieve hole 312, and also need to ensure that the adhesive smoke larger than the first preset diameter cannot fall out from the second sieve hole 312. The specific values ​​of the preset size and the first preset diameter are obtained through experimental tests, and the parameters, steps, etc. related to the experimental tests of the specific values ​​of the preset size and the first preset diameter are conventional techniques of those skilled in the art, and will not be elaborated here.

[0099] For some examples, see Figure 4 and Figure 7 The third vibration sorting component 32 is a plate, and in the projection along the gravity direction, the projection of the first vibration sorting component 30 is located within the projection range of the second vibration sorting component 31, and the projection of the second vibration sorting component 31 is located within the projection range of the third vibration sorting component 32.

[0100] It can be understood that the second vibration sorting component 31 can completely receive the sub-materials dropped from the first vibration sorting component 30 , and the third vibration sorting component 32 can completely receive the target materials dropped from the second vibration sorting component 31 .

[0101] For some examples, see Figure 4 and Figure 7 The vibration sorting device 300 also includes a negative pressure component 600, which includes a negative pressure member 60, a suction member and a pipe 61 connected between the negative pressure member 60 and the suction member. The suction member can be controlled and is used to absorb the materials stuck on the first vibration sorting member 30 and the second vibration sorting member 31 under the action of the negative pressure generated by the negative pressure member 60.

[0102] In the present application, the negative pressure generated by the negative pressure member 60 is controlled, and the materials stuck on the first vibration sorting member 30 and the second vibration sorting member 31 are aligned through the suction member, so that the stuck materials are sucked into the negative pressure member 60 through the suction member to ensure the normal operation of the vibration sorting device 300.

[0103] For some examples, see Figure 4 and Figure 7 The negative pressure assembly 600 of the vibration sorting device 300 and the negative pressure assembly 600 of the air sorting device 100 have the same structure, and the negative pressure assembly 600 includes a negative pressure piece 60 and a plurality of pipes 61. The negative pressure piece 60 is connected to the vibration sorting device 300 and the air sorting device 100 respectively through different pipes 61.

[0104] For some examples, see Figure 4 and Figure 7 The negative pressure assembly 600 further includes a mechanical arm connected to the suction member and used to control the suction member to move along a preset path to the surface of the first vibration sorting member 30 and the second vibration sorting member 31 that is opposite to the direction of gravity.

[0105] For some examples, see Figure 1 and Figure 2 The first feeding device 400 includes a feeding body 40 and a feeding plate 41. The feeding body 40 includes a driving wheel 401, a driven wheel 402 and a conveyor belt 403 connected between the driving wheel 401 and the driven wheel 402. The feeding plate 41 is set at an angle to the surface of the conveyor belt 403, and the feeding plates 41 are arranged at intervals along the conveying direction of the conveyor belt 403. The conveying direction of the conveyor belt 403 is inclined upward along the direction opposite to gravity.

[0106] It can be understood that the raw material is placed on the conveyor belt 403 from the feeding end of the first feeding device 400. Since the conveyor belt 403 is tilted upward relative to the horizontal direction, the feeding plate 41 supports and prevents the raw material from sliding down, thereby lifting the raw material to the discharge end of the first feeding device 400. The angle of the conveyor belt 403 relative to the horizontal direction is 5 degrees to 70 degrees, preferably 60 degrees.

[0107] Specifically, the driving wheel 401 is arranged downstream of the first feeding device 400, and the driven wheel 402 is arranged downstream of the first feeding device 400. The driving wheel 401 is driven by a motor, and the conveyor belt 403 is respectively tensionedly sleeved on the driving wheel and the driven wheel 402 to move forward in a cycle under the rotation of the driving wheel 401.

[0108] The specific style of the feeding plate 41 is not limited. In some embodiments, see Figure 1 and Figure 2 The feed plates 41 have the same height and are evenly spaced along the extending direction of the conveyor belt 403. The feed plates 41 are substantially vertically disposed on the conveying surface of the conveyor belt 403 and are spaced at a certain distance. Thus, since the feed plates 41 have the same height and the intervals between adjacent feed plates 41 are constant, the volume of raw materials that can be lifted by each feed plate 41 is constant, so that when the raw materials are poured into the feed hopper, the purpose of evenly lifting the raw materials can be achieved, which facilitates the air separation of the air separation device 100.

[0109] For some examples, see Figure 1 and Figure 2 The first feeding device 400 is provided with a storage space 42 having a preset capacity at one end downstream of the conveying direction, and the storage space 42 is used to store raw materials.

[0110] For some examples, see Figure 1 and Figure 2 The screening system 200 also includes a second feeding device 500 , which is located downstream of the first feeding device 400 in the conveying direction and connected to the first feeding device 400 . The second feeding device 500 is used to convey the raw materials to the first feeding device 400 .

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0112] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
