Description

Technical Field

[0001] This application relates to the technical field of tobacco impurity removal, and particularly to a high-voltage electrostatic impurity removal device. Background Art

[0002] In the long-established and technology-intensive field of tobacco processing, the impurity removal treatment of tobacco leaves has always occupied a crucial position. As a key link to improve product quality, ensure production efficiency, and protect consumer health, the innovation and development of impurity removal technology have always been the focus of attention in the tobacco industry. Traditional impurity removal methods, such as mechanical screening and pneumatic impurity removal, although can meet the production requirements to a certain extent, but when using traditional impurity removal methods to remove light and large-volume impurities (such as weeds, large pieces of hemp rope, etc.), it is easy to remove impurities and tobacco leaf fragments together, and the impurity removal effect is not good. Utility Model Content

[0003] In order to achieve the precise separation and removal of light and large-volume impurities in tobacco leaves and reduce the misremoval rate of tobacco leaf fragments, this application provides a high-voltage electrostatic impurity removal device.

[0004] A high-voltage electrostatic impurity removal device provided by this application adopts the following technical solutions:

[0005] A high-voltage electrostatic impurity removal device includes a housing and a vibrating conveyor. The vibrating conveyor is located below the housing. A number of high-voltage electrostatic rollers are rotatably connected in the housing. A driving component for driving the rotation of the number of high-voltage electrostatic rollers is provided on the housing. An impurity removal component is installed on the first housing. The impurity removal component is connected to an impurity removal box. The impurity removal component separates the impurities adsorbed on the high-voltage electrostatic rollers from the high-voltage electrostatic rollers and discharges them into the impurity removal box. A partition component for separating it from the impurity removal component is provided in the impurity removal box. The impurity removal box is connected to an extraction component for extracting the internal impurities thereof. The conveying surface of the vibrating conveyor is close to the bottom of the high-voltage electrostatic rollers.

[0006] By adopting the above technical solutions, the vibrating conveyor conveys the tobacco leaves in a flat manner, ensuring that the tobacco leaves are evenly dispersed during the conveying process and avoiding caking, providing good conditions for subsequent electrostatic impurity removal. When the tobacco leaf flow passes through the bottom of the high-voltage electrostatic rollers, the high-voltage electrostatic impurity removal machine adsorbs and separates the light and large-volume impurities (such as weeds, large pieces of hemp rope, etc.) above the tobacco leaf flow by generating a strong electrostatic field. By adjusting the intensity and distribution of the electrostatic field, the removal efficiency of impurities and the misabsorption rate of tobacco leaf fragments can be effectively controlled.

[0007] The sundries adsorbed on the high-voltage electrostatic roller are separated into the impurity removal box through the impurity removal component. When the impurities stored in the impurity removal box reach a certain amount, the partition component separates the impurity removal box from the impurity removal component, and then the extraction component is started. The extraction component sucks away the impurities in the impurity removal box. After the impurity removal box is sucked clean, the partition component is opened again to enable the impurity removal box to receive materials normally, thus avoiding the situation that tobacco leaf fragments are accidentally sucked during the extraction process. Thereby, the precise separation and removal of light and large-volume sundries in tobacco leaves are realized, and the misremoval rate of tobacco leaf fragments is reduced.

[0008] Optionally, the impurity removal component includes a dust-proof cover. A plurality of impurity removal openings are formed at the bottom of the dust-proof cover. The impurity removal openings correspond to the high-voltage electrostatic rollers one by one. There is a feeding space between the impurity removal openings and one side of the high-voltage electrostatic rollers. A scraper is connected to the bottom plate of the dust-proof cover. The scraper corresponds to the impurity removal openings one by one. The scraper is attached to the high-voltage electrostatic roller. A guiding inclined surface is arranged on the bottom plate of the dust-proof cover. The bottom of the dust-proof cover is communicated with the impurity removal box. The feeding part of the impurity removal box is communicated with the discharging side of the guiding inclined surface.

[0009] By adopting the above technical solution, after the impurities adhere to the high-voltage electrostatic roller, the driving component drives the high-voltage electrostatic roller to rotate. The high-voltage electrostatic roller drives the impurities to rotate. After the impurities enter the dust-proof cover from the impurity removal openings, the scraper scrapes off the impurities on the high-voltage electrostatic roller, and then the impurities fall into the impurity removal box along the guiding inclined surface of the bottom plate of the dust-proof cover, realizing the automatic cleaning of the impurities adsorbed on the high-voltage electrostatic roller.

[0010] Optionally, the scraper is an arc-shaped plate and is attached to the high-voltage electrostatic roller.

[0011] Optionally, the partition component includes a partition plate. The bottom of the partition plate extends into the impurity removal box. The partition plate disconnects the feeding part of the impurity removal box from the discharging side of the guiding inclined surface. A first motor is arranged on the impurity removal box. The first motor is connected with a gear. The top of the partition plate extends out of the impurity removal box. A rack is installed on the part of the partition plate extending out of the impurity removal box. The gear meshes with the rack.

[0012] By adopting the above technical solution, before extracting the impurities in the impurity removal box, the first motor is started. The first motor drives the gear to rotate. The gear drives the rack to move. The rack drives the partition plate to descend, so that the partition plate separates the feeding part of the impurity removal box from the discharging part of the guiding inclined surface, avoiding accidentally sucking in tobacco leaf fragments when extracting the impurities.

[0013] Optionally, the extraction component includes an exhaust fan. The exhaust fan is connected with a receiving cylinder. A filter screen is installed at the air suction port of the exhaust fan. A collection box is installed at one end of the receiving cylinder far away from the exhaust fan. One end of the receiving cylinder close to the exhaust fan is communicated with the impurity removal box.

[0014] By adopting the above technical solution, the exhaust fan sucks to make the inside of the material receiving cylinder in a negative pressure state. The filter screen blocks impurities from entering the exhaust fan. After sucking for a certain period of time, the exhaust fan stops, and the impurities freely fall into the collection box, realizing the extraction of impurities in the impurity removal box.

[0015] Optionally, the driving assembly includes a second motor. The driving shaft of the second motor and each of the high-voltage electrostatic rollers are connected with pulleys, and the pulleys are jointly wound with a conveyor belt.

[0016] By adopting the above technical solution, driven by the second motor, the conveyor belt drives to make each pulley rotate simultaneously, and then makes multiple high-voltage electrostatic rollers rotate simultaneously.

[0017] Optionally, the high-voltage electrostatic rollers are arranged in two rows along the length direction of the housing. The two second motors are located between the two rows of high-voltage electrostatic rollers, and the driving shafts of the two second motors face opposite directions.

[0018] Optionally, the scraper, the pulley and the conveyor belt are all made of insulating materials.

[0019] By adopting the above technical solution, it is avoided that the high-voltage electrostatic roller conducts electricity to the housing, improving the safety of production.

[0020] In summary, the present application includes at least one of the following beneficial technical effects:

[0021] 1. The vibrating conveyor spreads and conveys the tobacco leaves flatly, ensuring that the tobacco leaves are evenly dispersed during the conveying process and avoiding caking, providing good conditions for subsequent electrostatic impurity removal. When the tobacco leaf flow passes through the bottom of the high-voltage electrostatic roller, the high-voltage electrostatic impurity removal machine generates a strong electrostatic field to adsorb and separate the light and large-volume sundries (such as weeds, large pieces of hemp rope, etc.) on the upper part of the tobacco leaf flow. By adjusting the intensity and distribution of the electrostatic field, the rejection efficiency of sundries and the mis-absorption rate of tobacco leaf fragments can be effectively controlled;

[0022] 2. The sundries adsorbed on the high-voltage electrostatic roller are separated into the impurity removal box through the impurity removal assembly. When the impurities stored in the impurity removal box reach a certain amount, the partition assembly separates the impurity removal box from the impurity removal assembly, and then the extraction assembly is started. The extraction assembly sucks away the impurities in the impurity removal box. After the impurity removal box is sucked clean, the partition assembly is opened again to make the impurity removal box receive materials normally, so as to avoid the situation that tobacco leaf fragments are mis-absorbed during the extraction process. Thus, the precise separation and removal of light and large-volume sundries in the tobacco leaves are realized, and the mis-removal rate of tobacco leaf fragments is reduced.

Detailed implementation manners

[0027] The following further Figures 1-3 elaborates on the present application in conjunction with the attached

[0028] The embodiment of the present application discloses a high-voltage electrostatic impurity removal device.

[0029] As Figure 1 , the high-voltage electrostatic impurity removal device includes a housing 1 and a vibrating conveyor 2. The housing 1 is located above the vibrating conveyor 2. A plurality of high-voltage electrostatic rollers 3 are rotatably connected in the housing 1. The high-voltage electrostatic rollers 3 are arranged in two rows along the length direction of the housing 1. Two driving components 4 are provided on the housing 1. Each of the two driving components 4 drives one row of high-voltage electrostatic rollers 3 to rotate. The driving component 4 includes a second motor 41. The two second motors 41 are located between the two rows of high-voltage electrostatic rollers 3. The driving shafts of the two second motors 41 face opposite directions. The driving shafts of the second motors 41 and each high-voltage electrostatic roller 3 are both connected with pulleys 42. The pulleys 42 are jointly wound with a conveyor belt 43. The pulleys 42 and the conveyor belt 43 are both made of insulating materials, such as phenolic resin. The conveying surface of the vibrating conveyor 2 is arranged close to the high-voltage electrostatic rollers 3.

[0030] Two impurity removal components 5 are arranged on the housing 1, each impurity removal component 5 corresponds to a row of high-voltage electrostatic rollers 3 one by one, and the impurity removal component 5 separates the impurities adsorbed on the high-voltage electrostatic rollers 3 from the high-voltage electrostatic rollers 3. The impurity removal component 5 includes a dust cover 51, which is arranged on the top of the housing 1 and covers a row of high-voltage electrostatic rollers 3. The dust cover 51 is provided with a plurality of impurity removal ports 511, each impurity removal port 511 corresponds to a high-voltage electrostatic roller 3 one by one, and the impurity removal ports 511 and the high-voltage electrostatic rollers 3 leave a feeding space for impurities to enter the impurity removal ports 511, and the bottom plate of the dust cover 51 is connected with a plurality of scrapers 52, and the scrapers 52 are made of insulating materials, such as phenolic resin. The scrapers 52 are arc-shaped plates, and the scrapers 52 are attached to the side of the high-voltage electrostatic rollers 3 away from the feeding space. The inner bottom wall of the bottom plate of the housing 1 is arranged as a guide slope 53, and the guide slope 53 is arranged obliquely along the length direction of the high-voltage electrostatic rollers 3, and the side of the bottom plate of the housing 1 with a low elevation is commonly connected with the impurity removal box 6.

[0031] like Figure 2 and Figure 3 The impurity removal box 6 is provided with a partition assembly 7, which includes a first motor 71 and a partition plate 72. The first motor 71 is provided at the top of the impurity removal box 6. A gear 73 is coaxially fixed to the driving shaft of the first motor 71. The bottom of the partition plate 72 extends into the impurity removal box 6. The top of the partition plate 72 extends out of the impurity removal box 6. A rack 74 is provided at the portion of the partition plate 72 extending out of the impurity removal box 6. The rack 74 is arranged in the vertical direction and meshes with the gear 73. When the bottom of the rack 74 contacts the top of the impurity removal box 6, the partition plate 72 separates the inlet of the impurity removal box 6 from the outlet of the guide slope 53.

[0032] like Figure 1 The two impurity removal boxes 6 are each located on one side of the shell 1. An extraction component 8 is provided at the feeding end of the vibrating conveyor 2. The extraction component 8 includes an exhaust fan 81. The exhaust fan 81 is connected to a receiving barrel 82. A filter screen 83 is installed at the exhaust port of the exhaust fan 81. A collecting box 84 is installed at one end of the receiving barrel 82 away from the exhaust fan 81. The end of the receiving barrel 82 close to the exhaust fan 81 is connected to the two impurity removal boxes 6.

[0033] The vibrating conveyor 2 flattens the tobacco leaves for transportation, ensuring that the tobacco leaves are evenly dispersed during transportation to avoid agglomeration, providing good conditions for subsequent electrostatic impurity removal. When the tobacco flow passes through the bottom of the high-voltage electrostatic roller 3, the high-voltage electrostatic impurity remover generates a strong electrostatic field to adsorb and separate the light and large-volume debris (such as weeds, large pieces of hemp rope, etc.) on the upper part of the tobacco flow. By adjusting the intensity and distribution of the electrostatic field, the removal efficiency of debris and the rate of tobacco leaf fragments being accidentally sucked can be effectively controlled.

[0034] The second motor 41 remains in the starting state, causing the high-voltage static roller 3 to rotate continuously. The high-voltage static roller 3 drives the impurities to rotate. After the impurities enter the dust-proof cover 51 from the impurity removal port 511, the scraper 52 scrapes off the impurities on the high-voltage static roller 3, and then the impurities fall into the impurity removal box 6 along the guiding inclined surface 53 of the bottom plate of the dust-proof cover 51, realizing the automatic cleaning of the impurities adsorbed on the high-voltage static roller 3, and enabling the high-voltage static roller 3 to continuously maintain an excellent state of being able to stably adsorb sundries.

[0035] When the impurities stored in the impurity removal box 6 reach a certain amount, the first motor 71 is started. The first motor 71 drives the gear 73 to rotate, the gear 73 drives the rack 74 to move, and the rack 74 drives the partition plate 72 to descend, so that the partition plate 72 separates the feeding place of the impurity removal box 6 and the discharging place of the guiding inclined surface 53. Then the exhaust fan 81 is started. When the exhaust fan 81 is started, the inside of the material receiving cylinder 82 is in a negative pressure state. The filter net 83 blocks the impurities from entering the exhaust fan 81. After each extraction for a period of time, the exhaust fan 81 stops, and the impurities freely fall into the collection box 84, realizing the extraction of the impurities in the impurity removal box 6. After the impurity removal box 6 is extracted clean, the partition plate 72 is opened again to enable the impurity removal box 6 to receive materials normally, so as to avoid the situation that tobacco leaf fragments are accidentally sucked during the extraction process. Thus, the precise separation and removal of light and large-volume sundries in tobacco leaves are realized, and the misremoval rate of tobacco leaf fragments is reduced.

[0036] The implementation principle of the embodiment of the present application is as follows: The vibrating conveyor 2 conveys the tobacco leaves in a flat manner, ensuring that the tobacco leaves are evenly dispersed during the conveying process and avoiding caking, providing good conditions for subsequent electrostatic impurity removal. When the tobacco leaf flow passes under the high-voltage static roller 3, the high-voltage electrostatic impurity removal machine adsorbs and separates the light and large-volume sundries (such as weeds, large pieces of hemp ropes, etc.) on the upper part of the tobacco leaf flow by generating a strong electrostatic field. By adjusting the intensity and distribution of the electrostatic field, the rejection efficiency of sundries and the misabsorption rate of tobacco leaf fragments can be effectively controlled.

[0037] The sundries adsorbed on the high-voltage static roller 3 are separated into the impurity removal box 6 through the impurity removal assembly 5. When the impurities stored in the impurity removal box 6 reach a certain amount, the partition assembly 7 separates the impurity removal box 6 from the impurity removal assembly 5, and then the extraction assembly 8 is started. The extraction assembly 8 sucks away the impurities in the impurity removal box 6. After the impurity removal box 6 is extracted clean, the partition assembly 7 is opened again to enable the impurity removal box 6 to receive materials normally, so as to avoid the situation that tobacco leaf fragments are accidentally sucked during the extraction process. Thus, the precise separation and removal of light and large-volume sundries in tobacco leaves are realized, and the misremoval rate of tobacco leaf fragments is reduced.

[0038] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
