Description

Technical Field

[0001] This utility model relates to the field of tobacco processing technology, and in particular to a tobacco pneumatic conveying and lifting device. Background Technology

[0002] In the process of air-sorting tobacco leaves, the whole tobacco leaves are generally first torn into sheets. Then, impurities are removed from the sheets to a certain size. Next, the sheets are moistened, and finally, they are dried to a certain degree before being sent to the air-sorting machine. During the drying process, since the tobacco drying equipment is located at a lower position while the air-sorting machine is at a higher position, a conveyor system is needed to connect the lower-position tobacco drying equipment to the higher-position air-sorting machine to transport the dried tobacco leaves from the lower position to the higher position.

[0003] Existing conveying devices that connect low-level tobacco drying equipment with high-level air separators generally employ a conveying structure that connects multiple conveying devices of different heights (multiple conveying devices of different heights: horizontal conveying devices connected in series with multiple conveying devices inclined to the ground) to deliver the dried tobacco leaves to the air separator for air separation.

[0004] Although the above methods can send the low-level dried tobacco leaves to the high-level air separator for air separation, there are still the following defects in actual use: (1) Since the conveying device is composed of multiple conveying devices of gradually different heights connected in series, the space occupied by the conveying device in the re-drying workshop is relatively large.

[0005] (2) In the process of conveying the dried tobacco leaves to the high-level air separator, it is necessary to pass through multiple conveying devices of different heights before it can be conveyed to the air separator, so the conveying efficiency of the tobacco leaves is significantly lower.

[0006] Therefore, it is necessary to improve the existing tobacco leaf lifting structure that transports tobacco leaves from a low position to a high position in order to solve the problems of low tobacco leaf conveying efficiency caused by the large space occupied by multiple conveying devices of gradually different heights in the re-drying workshop due to the multiple conveying devices of gradually different heights required to transport tobacco leaves to the air separator. Utility Model Content

[0007] The purpose of this utility model is to propose a tobacco leaf pneumatic conveying and lifting device to solve the problems of low tobacco leaf conveying efficiency caused by the large space occupied by multiple conveying devices of varying heights in the re-drying workshop and the need for tobacco leaves to pass through multiple conveying devices of varying heights before being transported to the air separator in the existing tobacco leaf lifting structure.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0009] A tobacco leaf pneumatic conveying and lifting device, comprising

[0010] The tobacco leaf sorting bin has an inlet that connects to the discharge end of the low-level tobacco leaf belt conveyor and an outlet that connects to the inlet of the high-level air separator.

[0011] The flow guide baffle is located inside the tobacco leaf distribution bin and is connected to the inner wall of the tobacco leaf distribution bin. The flow guide baffle divides the tobacco leaf distribution bin into a tobacco leaf temporary storage area and a tobacco leaf lifting and conveying area. The inlet of the tobacco leaf distribution bin is located in the tobacco leaf temporary storage area, and the outlet of the tobacco leaf distribution bin is located in the tobacco leaf lifting and conveying area.

[0012] The tobacco leaf sorting component has rotating ends that are rotatably connected to the side wall of the tobacco leaf sorting bin. The tobacco leaf sorting component is rotatably positioned at the separation gap between the tobacco leaf temporary storage area and the tobacco leaf lifting and conveying area. The separation gap is defined by the bottom of the guide baffle and the bottom of the tobacco leaf sorting bin. The sorting plates in the tobacco leaf sorting component have gaps between them and the bottom of the guide baffle and the bottom of the arc-shaped tobacco leaf sorting bin.

[0013] The tobacco leaf pneumatic conveyor is located within the tobacco leaf lifting and conveying area. It is installed at the bottom of another arc-shaped tobacco leaf distribution bin corresponding to the tobacco leaf lifting and conveying area, with the blowing end of the tobacco leaf pneumatic conveyor facing into the tobacco leaf lifting and conveying area.

[0014] Preferably, the tobacco leaf sorting component includes a motor, a sorting shaft, and sorting plates; the motor is located on one of the outer walls of the tobacco leaf sorting bin, and the motor output shaft is connected to one end of the sorting shaft that is rotatably connected to the side wall of the tobacco leaf sorting bin; sorting plates are spaced apart on the outer wall of the sorting shaft located inside the tobacco leaf sorting bin and at the dividing gap, and four sorting plates are arranged along the outer wall of the sorting shaft.

[0015] Preferably, the angle between adjacent material distribution plates is 90°.

[0016] Preferably, the tobacco leaf pneumatic conveying component includes tobacco leaf pneumatic conveying holes, an air collecting chamber, a pneumatic conveying pipe, and an air compressor; the tobacco leaf pneumatic conveying holes are arranged in an array at the bottom of the arc-shaped tobacco leaf distribution chamber corresponding to the tobacco leaf lifting and conveying area, and the tobacco leaf pneumatic conveying hole closest to the distribution plate is spaced apart from the end of the distribution plate which is horizontal and far away from the distribution axis in the horizontal direction. The tobacco leaf pneumatic conveying holes are connected to the inner cavity of the air collecting chamber connected to the bottom of the arc-shaped tobacco leaf distribution chamber. The inner cavity of the air collecting chamber is connected to the air inlet end of the pneumatic conveying pipe, and the air outlet end of the pneumatic conveying pipe is connected to the air outlet end of the air compressor placed on the ground.

[0017] Preferably, the air compressor is any one of reciprocating piston type, rotary vane type, or rotary screw type.

[0018] Preferably, the flow guide baffle is vertically arranged inside the tobacco leaf distribution bin, and the two side walls of the flow guide baffle are respectively connected to the inner side wall of the tobacco leaf distribution bin. The end of the flow guide baffle away from the dividing notch and one of the inner side walls of the tobacco leaf distribution bin near the air separator define the outlet of the tobacco leaf distribution bin.

[0019] Preferably, the inlet of the tobacco leaf distribution bin is located at the junction of the discharge end of the tobacco leaf conveyor and the inlet end of the tobacco leaf temporary storage area.

[0020] In operation, when the tobacco leaf pneumatic conveying and lifting device transports the dried tobacco leaves from the low-level drying equipment to the high-level air separator, the dried leaves are first transported to the tobacco leaf temporary storage area in the tobacco leaf distribution bin via the low-level belt conveyor. Then, the tobacco leaf separating component located at the gap between the tobacco leaf temporary storage area and the tobacco leaf lifting and conveying area is driven to move the tobacco leaves that have fallen into the tobacco leaf temporary storage area to the tobacco leaf lifting and conveying area. Finally, the tobacco leaf pneumatic conveying component located at the bottom of the tobacco leaf distribution bin corresponding to the tobacco leaf lifting and conveying area blows air upwards, conveying the tobacco leaves that were previously moved into the tobacco leaf lifting and conveying area vertically to the outlet of the tobacco leaf distribution bin and then into the high-level air separator. This completes the process of sending the tobacco leaves dried by the low-level drying equipment to the high-level air separator, eliminating the need for multiple conveying devices of varying heights to transport the dried tobacco leaves to the air separator as in the traditional method.

[0021] Compared with the prior art, the present invention has at least one of the following beneficial effects:

[0022] The tobacco leaf pneumatic conveying and lifting device of this utility model can first transport the dried tobacco leaves from the low-level drying equipment to the high-level air separator via a low-level belt conveyor to the tobacco leaf temporary storage area in the tobacco leaf distribution bin. Then, the tobacco leaf separating component located at the gap between the tobacco leaf temporary storage area and the tobacco leaf lifting and conveying area is driven to move the tobacco leaves that have fallen into the tobacco leaf temporary storage area to the tobacco leaf lifting and conveying area. Finally, the tobacco leaf pneumatic conveying component located at the bottom of the tobacco leaf distribution bin corresponding to the tobacco leaf lifting and conveying area blows air upwards, conveying the tobacco leaves that were previously moved into the tobacco leaf lifting and conveying area vertically to the outlet of the tobacco leaf distribution bin and then into the high-level air separator. This solves the problems of low tobacco leaf conveying efficiency caused by the large space occupied by multiple conveying devices of varying heights in the re-drying workshop and the need for tobacco leaves to pass through multiple conveying devices of varying heights to reach the air separator in the existing tobacco leaf lifting structure.

Detailed Implementation

[0028] like Figure 1-4 As shown, to make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] Example

[0030] Existing conveying devices that connect low-level tobacco drying equipment with high-level air separators generally employ a conveying structure that connects multiple conveying devices of different heights (multiple conveying devices of different heights: horizontal conveying devices connected in series with multiple conveying devices inclined to the ground) to deliver the dried tobacco leaves to the air separator for air separation.

[0031] Although the above method can send the dried tobacco leaves at the lower level to the air separator at the higher level for air separation, there are still the following defects in actual use: (1) Since the conveying device is composed of multiple conveying devices of different heights connected in series, the space occupied by the conveying device in the re-drying workshop is relatively large; (2) In the process of conveying the dried tobacco leaves to the air separator at the higher level, it is necessary to pass through multiple conveying devices of different heights to reach the air separator, so the tobacco leaf conveying efficiency is significantly lower.

[0032] Therefore, this application proposes a tobacco leaf pneumatic conveying and lifting device to solve the problems of low tobacco leaf conveying efficiency caused by the large space occupied in the re-drying workshop due to multiple conveying devices of gradually different heights in the existing tobacco leaf lifting structure, and the need for tobacco leaves to pass through multiple conveying devices of gradually different heights before being conveyed to the air separator.

[0033] For details, please refer to Figure 1-4A tobacco leaf pneumatic conveying and lifting device includes a tobacco leaf distribution bin 1, a guide baffle 4, a tobacco leaf sorting component 7, and a tobacco leaf pneumatic conveying component 10. The tobacco leaf distribution bin 1 has an inlet 2 connected to the discharge end of a lower-positioned tobacco leaf belt conveyor, and an outlet 3 connected to the inlet end of a higher-positioned pneumatic separator. The guide baffle 4 is located inside the tobacco leaf distribution bin 1 and connected to its inner wall, dividing the bin into a tobacco leaf area 5 and a tobacco leaf lifting and conveying area 6. The inlet 2 of the tobacco leaf distribution bin 1 is located in the tobacco leaf temporary storage area 5, and the outlet 3 is located in the tobacco leaf lifting and conveying area 6. The rotating ends of the tobacco leaf sorting component 7 are rotatably connected to the side walls of the tobacco leaf distribution bin 1. The leaf sorting component 7 is rotatably positioned at the separation gap 8 between the tobacco leaf temporary storage area 5 and the tobacco leaf lifting and conveying area 6. The separation gap 8 is defined by the bottom of the guide baffle 4 and the bottom of the tobacco leaf distribution bin 1. The material sorting plate 9 in the tobacco leaf sorting component 7 leaves gaps with the bottom of the guide baffle 4 and the bottom of the arc-shaped tobacco leaf distribution bin 1. The tobacco leaf pneumatic conveyor 10 is located in the tobacco leaf lifting and conveying area 6. The tobacco leaf pneumatic conveyor 10 is positioned at the bottom of another arc-shaped tobacco leaf distribution bin 1 corresponding to the tobacco leaf lifting and conveying area 6. The blowing end of the tobacco leaf pneumatic conveyor 10 faces the tobacco leaf lifting and conveying area 6.

[0034] In practical applications, when using this tobacco leaf pneumatic conveying and lifting device to transport tobacco leaves dried by the low-level drying equipment to the high-level air separator, the dried leaves can first be transported via a low-level belt conveyor to the tobacco leaf temporary storage area 5 in the tobacco leaf distribution bin 1. Then, the tobacco leaf separating component 7 located at the separation gap 8 between the tobacco leaf temporary storage area 5 and the tobacco leaf lifting and conveying area 6 is driven to move, pushing the tobacco leaves that have fallen into the tobacco leaf temporary storage area 5 into the tobacco leaf lifting and conveying area 6. Finally, the tobacco leaf pneumatic conveying component 10 located at the bottom of the tobacco leaf distribution bin 1 corresponding to the tobacco leaf lifting and conveying area is driven to blow air upwards, pushing the previously pushed tobacco leaves into the tobacco leaf lifting and conveying area 6. The tobacco leaves in the conveying area 6 are vertically conveyed to the outlet 3 of the tobacco leaf distribution bin 1 and then enter the high-level air separator through the outlet 3 of the tobacco leaf distribution bin 1. This completes the process of sending the tobacco leaves dried by the low-level drying equipment to the high-level air separator. Unlike the traditional method, it does not require multiple conveying devices of varying heights to send the dried tobacco leaves to the air separator. This solves the problems of large space occupied by multiple conveying devices of varying heights in the re-drying workshop and low tobacco leaf conveying efficiency caused by the need for multiple conveying devices of varying heights to transport the tobacco leaves to the air separator in the existing tobacco leaf lifting structure.

[0035] It should be noted that although there are gaps between the material distribution plate 9 in the tobacco leaf distribution component 7 and the bottom of the guide baffle 4 and the bottom of the arc-shaped tobacco leaf distribution bin 1, the gaps are very small. The purpose of the gaps is to prevent the material distribution plate 9 in the tobacco leaf distribution component 7 from rigidly contacting the bottom of the guide baffle 4 and the bottom of the arc-shaped tobacco leaf distribution bin 1 when the component rotates.

[0036] It should be noted that the inlet 2 of the tobacco leaf distribution bin 1 is located at the junction of the discharge end of the tobacco leaf conveyor and the inlet end of the tobacco leaf temporary storage area 5, so that the tobacco leaves conveyed by the tobacco leaf conveyor after drying to a certain extent can smoothly enter the tobacco leaf temporary storage area 5; wherein, the inlet end of the tobacco leaf conveyor is connected to the discharge end of the tobacco leaf drying equipment, and the tobacco leaves that have been dried to a certain extent enter the tobacco leaf conveyor in a cooled state; wherein, the tobacco leaf conveyor is a mesh conveyor.

[0037] It should be noted that the flow guide baffle 4 is vertically arranged inside the tobacco leaf distribution bin 1. The flow guide baffle 4 is connected to the inner wall of the tobacco leaf distribution bin 1. The end of the flow guide baffle 4 away from the dividing notch 8 is connected to one of the inner walls of the tobacco leaf distribution bin 1 near the leaf threshing machine to define the outlet 3 of the tobacco leaf distribution bin 1.

[0038] Please see Figure 1-4 The tobacco leaf sorting component 7, used to transfer tobacco leaves temporarily stored in the tobacco leaf storage area 5 into the tobacco leaf lifting and conveying area 6, includes a motor 11, a sorting shaft 12, and sorting plates 9. The motor 11 is located on one of the outer walls of the tobacco leaf sorting bin 1. The output shaft of the motor 11 is connected to one end of one of the sorting shafts 12, which is rotatably connected to the side wall of the tobacco leaf sorting bin 1. Both ends of the shaft 12 are rotatably connected to the side wall of the tobacco leaf sorting bin 1. Sorting plates 9 are spaced apart on the outer wall of the sorting shaft 12 located inside the tobacco leaf sorting bin 1 and at the dividing gap 8. Four sorting plates 9 are arranged along the outer wall of the sorting shaft 12. The angle between adjacent sorting plates 9 is 90 degrees. A small gap is left between the sorting plates 9 and the inner wall of the tobacco leaf sorting bin 1 to prevent interference between the sorting plates 9 and the inner wall of the tobacco leaf sorting bin 1 during rotation.

[0039] In practical application, when the tobacco leaf sorting component 7 moves the tobacco leaves in the tobacco leaf temporary storage area 5 into the tobacco leaf lifting and conveying area 6, it first controls the motor 11 to indirectly drive the material sorting plate 9 to rotate at a certain angle. During the rotation of the material sorting plate 9 at a certain angle, the tobacco leaves that were temporarily stored in the tobacco leaf temporary storage area 5 are moved into the tobacco leaf lifting and conveying area 6. In this way, the amount of tobacco leaves moved into the tobacco leaf lifting and conveying area 6 each time can be controlled, which indirectly improves the effect of the tobacco leaf pneumatic conveyor 10 in the subsequent pneumatic conveying of tobacco leaves.

[0040] It should be noted that motor 11 is a stepper motor. Stepper motors are existing technology, and no improvements or designs have been made to them. Therefore, their structure will not be described in detail.

[0041] Please see Figure 1-4The tobacco leaf pneumatic conveying component 10 includes tobacco leaf pneumatic conveying holes 13, an air collecting chamber 14, a conveying pipe, and an air compressor. The tobacco leaf pneumatic conveying holes 13 are arranged in an array at the bottom of the arc-shaped tobacco leaf distribution chamber 1, which corresponds to the tobacco leaf lifting and conveying area 6. The tobacco leaf pneumatic conveying hole 13 closest to the distribution plate 9 is separated from the end of the distribution plate 9, which is horizontal and far away from the distribution shaft 12, in the horizontal direction. The tobacco leaf pneumatic conveying holes 13 are connected to the inner cavity of the air collecting chamber 14 on the outer bottom of the arc-shaped tobacco leaf distribution chamber 1. The inner cavity of the air collecting chamber 14 is connected to the air inlet end of the conveying pipe, and the air outlet end of the conveying pipe is connected to the air outlet end of the air compressor placed on the ground. The inner cavity of the air collecting chamber 14 is a cavity.

[0042] In practical applications, when the tobacco leaf pneumatic conveyor 10 conveys the tobacco leaves that have been pushed into the tobacco leaf lifting and conveying zone 6, it can drive the air compressor or air pump to work. The air output by the air compressor or air pump is then conveyed through the pneumatic conveying pipe and the air collection chamber 14 to the tobacco leaf pneumatic conveying hole 13 and blown towards the tobacco leaves that have been pushed into the tobacco leaf lifting and conveying zone 6 in advance, so as to convey the tobacco leaves that have been pushed into the tobacco leaf lifting and conveying zone 6 towards the feed end of the high-level air separator.

[0043] It should be noted that the tobacco leaf air conveying hole 13 closest to the material distribution plate 9 is spaced apart in the horizontal direction from one end of the material distribution plate 9 that is in a horizontal state and far away from the material distribution shaft 12. That is, when the material distribution plate 9 is in a horizontal state, the end of the material distribution plate 9 that is far away from the material distribution shaft 12 is a certain distance away in the horizontal direction from the tobacco leaf air conveying hole 13 closest to the material distribution plate 9. In this way, the tobacco leaves that are pushed into the tobacco leaf lifting conveyor area 6 will not be blocked by the material distribution plate 9 during the process of being air conveyed by the air blown out of the tobacco leaf air conveying hole 13.

[0044] It should be noted that the air compressor is any one of reciprocating piston, rotary vane, or rotary screw. The air compressor is existing technology and has not been improved or designed, so its structure will not be described in detail.

[0045] Although the present invention has been described herein with reference to several illustrative embodiments, it should be understood that many other modifications and implementations can be devised by those skilled in the art, which will fall within the scope and spirit of the principles disclosed herein. More specifically, various variations and modifications can be made to the components and / or layout of the subject matter combination within the scope of the disclosure, drawings, and claims. Besides variations and modifications to the components and / or layout, other uses will be apparent to those skilled in the art.
