Description

Technical Field

[0001] The present application relates to the technical field of tobacco processing, and in particular to a system for preparing a thick pulp sheet slurry for heated cigarettes. Background Art

[0002] Tobacco flakes are one of the important raw materials for tobacco products, and their preparation methods can be roughly divided into roller pressing, thick pulp method and papermaking method according to the process. Among them, the general preparation process of thick pulp method flakes is: crush the tobacco raw materials into 80-300 mesh tobacco powder to form material one, hydraulically crush and grind the fiberboard to form material two, mix material one, material two and auxiliary materials such as adhesives, glycerin, and spices according to the formula to form a slurry, and spread the slurry thinly on the steel belt through casting, blade coating, roller coating, etc. to form and dry, peel off the dried flakes and cut or roll them. The thick pulp method flakes used for heated cigarettes (i.e., heat not burn cigarettes, Heat Not Burning, HNB) can contain atomizers, and the atomizers are mainly glycerin and propylene glycol, which are generally added in the slurry preparation stage of the thick pulp method flakes.

[0003] In the aforementioned process, tobacco raw materials are generally ground dry. This has the following advantages: dry tobacco powder is less susceptible to deterioration during storage and has a smaller storage volume. The complete tobacco raw material formula can be ground and homogenized at once before being used in batches, making it more suitable for small-scale production. However, dry grinding generally requires pre-drying of the raw materials and moisture adjustment to ensure grinding quality; additional dust removal piping and equipment are required during grinding; and due to the small particle size, the processing environment and equipment must meet dust and explosion-proof requirements. These disadvantages increase the need for additional space and equipment investment for laboratory sample preparation and large-scale production, which do not require batch pulping.

[0004] Furthermore, as the heated tobacco market continues to expand and demand for increasingly diverse flavors grows, the raw materials for heated tobacco sheets are no longer limited to traditional tobacco scraps and shreds, which are byproducts of traditional cigarette manufacturing. High-quality boxed tobacco sheets are also being widely used. However, when boxed tobacco sheets are included in the raw material formula, the un-loosened tobacco sheets cannot be effectively cleaned of impurities by the spectral impurity removal equipment used in traditional cigarette making processes. These impurities, once crushed, can easily contaminate the raw materials, causing the sheet products to produce unpleasant odors. Utility Model Content

Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0053] See also Figures 1 to 4 As shown, a system for preparing thick pulp sheet slurry for heated cigarettes provided in accordance with an embodiment of the present application is schematically shown, comprising: at least one of a tobacco cutting processing device 100 or a sheet processing device 200, a process water feeding device 300, a primary crushing device 400, a wood pulp processing device 500, and a secondary crushing device 600.

[0054] Among them, the tobacco processing device 100 is used to process the tobacco raw materials into tobacco to form material one, the tobacco flake processing device 200 is used to mix tobacco fragments with tobacco flakes to form material two, the process water feeding device 300 is used to provide process water supply for the first-level crushing device 400, the first-level crushing device 400 is used to mix material one and / or material two and process water and wet-crush to form material three, the wood pulp processing device 500 is used to process the pulp board into wood pulp to form material four, and the second-level crushing device 600 is used to mix material three with material four and refine them to form material five.

[0055] When preparing the slurry for heated cigarettes, the tobacco processing device 100 processes the tobacco raw material into tobacco to form material one, the tobacco end processing device 200 mixes tobacco fragments with tobacco end to form material two, and material one and / or material two are quantitatively added to the primary crushing device 400. At the same time, the process water feeding device 300 quantitatively adds process water to the primary crushing device 400. The primary crushing device 400 mixes material one and / or material two and process water and wet-grinds them to form material three; the wood pulp processing device 500 processes the pulp board into wood pulp to form material four, and material three and material four are quantitatively added to the secondary crushing device 600. The secondary crushing device 600 mixes material three and material four and grinds them into material five, thereby completing the preparation of the slurry.

[0056] Therefore, in the preparation system of thick pulp flake slurry for heated cigarettes of the present application, the first-level crushing device 400 can perform wet coarse crushing on the material, and the second-level crushing device 600 can perform fine crushing and pulping and separation on the material. By wet crushing the tobacco raw materials, the preparation of thick pulp flake slurry for heated cigarettes is achieved, the crushing efficiency is high, the crushing effect is good, the tobacco powder yield is high, and the quality of the finished slurry is improved. In addition, there is no need for dust removal and dust explosion-proof equipment, and there is no dust at the production site, which reduces the related infrastructure and equipment investment as well as maintenance and management work, and facilitates clean production. Some equipment can also use the producer's existing equipment, reducing the producer's equipment idleness and waste, reducing costs, etc.

[0057] In some embodiments, as Figure 1 As shown, the tobacco processing device 100 includes a tobacco processing machine (not shown), a first feeder 110, and a first online moisture meter 120. The tobacco processing machine is used to loosen and rehydrate, air-separate, pre-blend, remove impurities, cut, and blend the tobacco sheets to form material 1. The first feeder 110 is used to convey material 1 processed by the tobacco processing machine to the primary pulverizing device 400. The first online moisture meter 120 is installed on the first feeder 110 and is used to detect the moisture content of material 1 conveyed by the first feeder 110.

[0058] The tobacco processing machine processes the tobacco strips into material 1, which is then fed into the first feeder 110. When the material on the first feeder 110 reaches the position corresponding to the first online moisture meter 120, the first online moisture meter 120 can detect the moisture content of material 1 conveyed by the first feeder 110. The moisture content determines the wet-based flow rate of material 1, facilitating control of the feed rate of material 1 to the primary crushing device 400 and the pre-filling of material 1. Thus, the tobacco processing machine first loosens and rehydrates the tobacco strips, allowing for better subsequent impurity removal and preventing contamination of the raw material by crushed impurities, which could cause the flake product to produce an unpleasant odor. This improves the purity of the material. Furthermore, the moisture content of material 1 detected by the first online moisture meter 120 facilitates control of the feed rate of material 1 to the primary crushing device 400 and the pre-filling of material 1.

[0059] Furthermore, the number of slices per tobacco pack during tobacco processing can be 5 to 6 or more, which helps loosen the tobacco sheets and improves the efficiency of subsequent tobacco sheet removal. A roller mechanism can be used for loosening and rehydration, on-site air separation, and spectral impurity removal. A tobacco stem cutter can be used, with a cut width of 0.1mm to 0.2mm. The tobacco sheets can be cut to a fixed length, reducing the length of the tobacco, preventing excessive entanglement of the tobacco, improving the uniformity of tobacco blending, and the smoothness of subsequent tobacco feeding. The first feeder 110 can be a belt conveyor, and the first online moisture meter 120 can be a moisture detector in the existing technology, which will not be described in detail here.

[0060] In some embodiments, as Figure 1 As shown, the flake processing device 200 includes a flake processing machine (not shown), a second feeder 210, and a second online moisture meter 220. The flake processing machine is used to loosen, remove impurities, and mix tobacco fragments and tobacco dust to form Material 2. The second feeder 210 is used to convey Material 2 processed by the flake processing machine to the primary pulverizing device 400. The second online moisture meter 220 is mounted on the second feeder 210 and is used to detect the moisture content of Material 2 conveyed by the second feeder 210. For example, the flake processing machine can use a horizontal ribbon mixer, a conical mixer, or other methods to mix the materials, and can use air conveying to remove impurities. The second feeder 210 can also use a belt conveyor, for example.

[0061] The flake processing machine processes tobacco shreds and tobacco dust into material 2, which is then fed into the second feeder 210. When the material on the second feeder 210 reaches the position corresponding to the second online moisture meter 220, the second online moisture meter 220 can detect the moisture content of the material 2 conveyed by the second feeder 210. The moisture content determines the wet-based flow rate of the material 2, facilitating control of the feed rate of the material 2 to the primary pulverizing device 400 and the pre-filling of the material 2. Thus, the flake processing machine facilitates the removal of impurities from the material, preventing contamination of the raw material by pulverized impurities, thereby improving the purity of the material. Furthermore, the moisture content of the material 2 detected by the second online moisture meter 220 facilitates control of the feed rate of the material 2 to the primary pulverizing device 400 and the pre-filling of the material 2.

[0062] In some embodiments, as Figure 1 As shown, the process water feeding device 300 includes a process water pump 310. The process water pump 310 is connected to the feed port of the primary pulverizing device 400 via a process water pipe 330. A process water flowmeter 320 is provided on the process water pipe 330. The process water flowmeter 320 is used to detect the flow rate of the process water and thereby regulate the supply of process water to the primary pulverizing device 400. Thus, the process water flowmeter 320 detects the flow rate of the process water and dynamically regulates the supply of process water to the primary pulverizing device 400 based on requirements such as the moisture content of material one, material two, and material three, thereby ensuring optimal wet pulverization.

[0063] In some embodiments, as Figure 2 As shown, the primary pulverizing device 400 includes a first feed bin 410 and a first pulverizing and refining bin 430. The tobacco processing device 100 is used to convey material 1 into the first feed bin 410, the tobacco flake processing device 200 is used to convey material 2 into the first feed bin 410, and the process water feeding device 300 is used to convey process water into the first feed bin 410. A first agitator 420 is provided in the first feed bin 410, and the first feed bin 410 is used to agitate and mix material 1 and / or material 2 with the process water. The first crushing and refining bin 430 is located below the first feed bin 410. The feed port at the upper end of the first crushing and refining bin 430 is connected to the discharge port at the lower end of the first feed bin 410. The discharge port at the lower end of the first crushing and refining bin 430 is connected to the first discharge pipe 440. The first crushing and refining bin 430 is used to wet-crush material one and / or material two as well as process water to form material three. The first discharge pipe 440 is used to transport material three to the secondary crushing device 600. A first valve 441 is provided on the first discharge pipe 440. The first valve 441 is used to open or close the first discharge pipe 440. The first crushing and refining bin 430 can adopt a colloid mill mechanism or a beating mechanism, etc.

[0064] When the primary pulverizing device 400 is operating, the tobacco processing device 100 and / or the tobacco flake processing device 200 and the process water feeding device 300 respectively deliver material 1 and / or material 2 and process water in a fixed quantity to the first feed bin 410. The first agitator 420 mixes the material 1 and / or material 2 and the process water in the first feed bin 410. The material then flows from the discharge port at the lower end of the first feed bin 410 through the feed port of the first pulverizing and refining bin 430, where it is wet-pulverized to form material 3. The moisture content of material 3 is controlled to be 70% to 90%, and the particle size is controlled to be 100 to 300 mesh. Material 3 is then discharged to the secondary pulverizing device 600 through the first discharge pipe 440. Thus, wet pulverization of the tobacco raw material to form material 3 is achieved, with high pulverizing efficiency and good pulverizing effect.

[0065] In some embodiments, as Figure 2 As shown, the first discharge pipe 440 is connected to the first circulation pipe 450, and the first circulation pipe 450 is provided with a second valve 451. The end of the first circulation pipe 450 away from the first discharge pipe 440 is connected to the feed port of the first feed bin 410, and the first circulation pipe 450 is located between the first valve 441 and the discharge port of the first crushing and refining bin 430.

[0066] In order to ensure that the material 3 is formed better, it is necessary to pre-fill the material 1 and / or the material 2 and pre-fill the primary crushing device 400 (ie, pre-fill the process water). Figure 2 、 Figure 7As shown, when material one is conveyed to the position corresponding to the first online moisture meter 120 and / or material two is conveyed to the position corresponding to the second online moisture meter 220, the conveying of material one and / or material two stops, and the first online moisture meter 120 and / or the second online moisture meter 220 respectively detect the moisture content of material one and / or material two, and judge whether the wet basis flow rate of material one and / or material two reaches the preset wet basis flow rate according to the moisture content of material one and / or material two. If the wet basis flow rate of material one and / or material two reaches the preset wet basis flow rate, material one and / or material two completes pre-filling. Close the first valve 441 on the first discharge pipe 440 of the first-level crushing device 400 and open the second valve 451 on the first circulation pipe 450 of the first-level crushing device 400, and inject process water into the first-level crushing device 400. The process water in the first-level crushing device 400 can only circulate into the first-level crushing device 400 through the discharge pipe and the circulation pipe in sequence. If the liquid level in the first feed bin 410 of the first-level crushing device 400 reaches the pre-filling level, turn off the process water pump 310 and keep the process water circulation in the first-level crushing device 400, then the first-level crushing device 400 completes the pre-filling. After pre-filling of material 1 and / or material 2 and the primary pulverizing device 400, material 1 and / or material 2 and process water are simultaneously and quantitatively delivered to the primary pulverizing device 400 for mixing and wet pulverization to form material 3. Simultaneously, the first valve 441 on the first discharge pipe 440 is opened and the opening of the second valve 451 on the first circulation pipe 450 is reduced, and material 3 in the primary pulverizing device 400 is discharged to the secondary pulverizing device 600 through the first discharge pipe 440. This allows for better formation of material 3, improves its quality, and facilitates subsequent processing of the material. In addition, after material one and / or material two and the primary crushing device 400 are pre-filled, since material one and / or material two are a certain distance away from the feed port of the first feed bin 410, in order to ensure that material one and / or material two are fed to the primary crushing device 400 synchronously with process water, the process water can be delayed for a certain time. When material one and / or material two are transported to the feed port of the first feed bin 410, material one and / or material two are fed to the first feed bin 410 of the primary crushing device 400 synchronously with process water.

[0067] In some embodiments, as Figures 2-3As shown, a liquid level detector 460 is also provided on the first feed bin 410, and the liquid level detector 460 is used to detect the liquid level (i.e., material level) in the first feed bin 410. The liquid level detector 460 may include a plurality of liquid level sensors spaced apart from top to bottom. For example, the liquid level detector 460 includes four pairs of liquid level sensors spaced apart from top to bottom, and the four pairs of liquid level sensors correspond to the upper liquid level, the upper middle liquid level, the lower middle liquid level, and the lower liquid level from top to bottom. For example, when the first-stage crushing device 400 is pre-filled, when the liquid level in the first feed bin 410 reaches the upper middle liquid level, the pre-filling of the first-stage crushing device 400 is completed. Figure 8 As shown, during the preparation process of material three by the primary pulverizing device 400, when the liquid level in the first feed bin 410 is lower than the lower liquid level, the device is stopped for inspection; when the liquid level in the first feed bin 410 is lower than the middle-lower liquid level, the opening of the first valve 441 of the first circulation pipe 450, the grinding disc speed of the primary pulverizing device 400, the feeding rate of material one and / or material two and process water are adjusted; when the liquid level in the first feed bin 410 is lower than the middle-upper liquid level, the operation is basically the same as when the liquid level in the first feed bin 410 is lower than the middle-lower liquid level; when the liquid level in the first feed bin 410 is lower than the upper liquid level, the opening of the first valve 441 of the first circulation pipe 450, the grinding disc speed of the primary pulverizing device 400, the feeding rate of material one and / or material two and process water are adjusted; when the liquid level in the first feed bin 410 is higher than the upper liquid level, the device is stopped for inspection. Thus, according to the specific situation of the liquid level in the first feeding bin 410, different operations and adjustments are performed to maintain a stable liquid level in the primary pulverizing device 400, thereby ensuring that the primary pulverizing device 400 can perform pulverization better and preventing factors such as fluctuations in process water flow during the production process from causing the liquid level to be too high, resulting in liquid material overflow, or the liquid level to be too low, resulting in material shortage in the pulverizing device. In addition, during the pulverizing process, the primary pulverizing device 400 and the secondary pulverizing device 600 can also control the load of the drive motor. When the motor current increases to the warning zone, the material supply is reduced. When the load of the drive motor continues to increase to the alarm line, the feeding is stopped urgently.

[0068] In some embodiments, as Figures 2-3 As shown, the first agitator 420 includes a stirring shaft (not shown), a drive motor (not shown), and a paddle 421. The paddle 421 is mounted on the stirring shaft and located at the lower end within the first feed bin 410. The drive motor is connected to the stirring shaft. The drive motor drives the stirring shaft to rotate at high speed, which in turn drives the paddle 421 to rotate at high speed, causing the paddle 421 to stir and mix the material within the first feed bin 410. This ensures that the material within the first feed bin 410 is better stirred and mixed.

[0069] Furthermore, the lower liquid level alarm line in the first feed bin 410 is set above the paddle 421. Thus, the paddle 421 can be kept stirring the material in the first feed bin 410 at all times, thereby ensuring that the drive motor load reflects the accuracy of the mixture ratio in the first feed bin 410.

[0070] Furthermore, the drive motor is equipped with a current monitor. This allows the ratio of the mixture in the first feed bin 410 to be determined based on the load on the drive motor, thereby regulating the feed rate of the tobacco raw material to the primary pulverizing device 400 and the emergency stop of the material transport to the secondary pulverizing device 600. This prevents an overabundance of tobacco raw material in the first feed bin 410, preventing a decrease in the fluidity of the solid-liquid mixture in the first feed bin 410 and the subsequent accumulation and blockage.

[0071] In some embodiments, the first crushing and refining chamber 430 is further provided with a grinding disc gap adjustment mechanism (not shown). The grinding disc gap adjustment mechanism can be driven by a motor or a hydraulic drive. Thus, the grinding disc gap adjustment mechanism can be used to adjust the grinding disc gap in the first crushing and refining chamber 430 according to different circumstances, thereby achieving better crushing and refining.

[0072] In some embodiments, the tobacco processing device 100 and / or the tobacco flake processing device 200 conveys material 1 and / or material 2 to the primary pulverizing device 400 via a first conveying mechanism 1000. The first conveying mechanism 1000 can be a belt conveyor. That is, material 1 and / or material 2 are first conveyed to the first conveying mechanism, which then conveys them to the primary pulverizing device 400. This facilitates better conveyance of material 1 and / or material 2 to the primary pulverizing device 400, resulting in higher efficiency.

[0073] In some embodiments, as Figure 1 As shown, the wood pulp processing device 500 includes a wood pulp processing machine, a third feeder 510, and a third online moisture meter 520. The wood pulp processing machine is used to wet-disintegrate the pulp sheet, perform solid-liquid separation, and loosen the pulp to form material 4. The third feeder 510 is used to transport the material 4 processed by the wood pulp processing machine to the secondary pulverization device 600. The third online moisture meter 520 is mounted on the third feeder 510 and is used to detect the moisture content of the material 4 transported by the third feeder 510. The wood pulp processing machine can use hydraulic pulping to defibrate the pulp sheet, centrifugal drying, screw extrusion, or other methods for solid-liquid separation, and a high-speed rake-type loosening mechanism to break the material into small pieces of wood pulp. The third feeder 510 can be a belt conveyor, for example.

[0074] The wood pulp processing machine processes the pulp sheet into material 4, controlling the moisture content of material 4 to less than 80%. Material 4 then enters the third feeder 510 for conveyance. When material 4 reaches the position corresponding to the third online moisture meter 520, the third online moisture meter 520 detects the moisture content of material 4. Based on the moisture content of material 4, the wet-basis flow rate of material 4 is determined to facilitate control of the feed rate of material 4 to the secondary pulverizing device 600. Thus, the pulp sheet is processed into wood pulp by the wood pulp processing machine, and the moisture content of material 4 is detected by the third online moisture meter 520, facilitating control of the feed rate of material 4 to the secondary pulverizing device 600.

[0075] In some embodiments, as Figure 4 As shown, the system for preparing thick pulp flake slurry for heated cigarettes of the present application further includes a mixing tank 700. The discharge port of the secondary pulverizing device 600 is connected to the feed port of the mixing tank 700. The discharge port of the mixing tank 700 is connected to a third discharge pipe 720. A third agitator 710 is provided in the mixing tank 700. Specifically, a shut-off valve 730, a slurry pump 740, and a three-way valve 750 are provided on the third discharge pipe 720. The shut-off valve 730 is located between the discharge port of the mixing tank 700 and the slurry pump 740. The slurry pump 740 is located between the shut-off valve 730 and the three-way valve 750. The first port of the three-way valve 750 is used to output material 5, and the second port of the three-way valve 750 is used for waste discharge. The third port of the three-way valve 750 is connected to the feed port of the secondary pulverizing device 600 via a second circulation pipe 760. It should be noted that the secondary crushing device 600 has a basically identical structure to the primary crushing device 400 described above. The secondary crushing device 600 includes a second feed bin (not shown) and a second crushing and refining bin (not shown). A second agitator (not shown) is provided in the second feed bin. The second feed bin is located above the second crushing and refining bin. The discharge port at the lower end of the second feed bin is connected to the feed port at the upper end of the second crushing and refining bin. The discharge port of the second crushing and refining bin is connected to the feed port at the upper end of the mixing tank 700 through a second discharge pipe (not shown). The gap of the grinding disc in the second crushing and refining bin can also be adjusted by a corresponding mechanism. The second discharge pipe can be connected to the feed port of the second feed bin without a circulation pipe. A plurality of liquid level sensors (not shown) arranged in sequence from bottom to top can also be provided on the second feed bin. The plurality of liquid level sensors can correspond to the lower liquid level, middle-lower liquid level, middle-upper liquid level and upper liquid level of the second feed bin, respectively. For details, please refer to the description of the primary crushing device 400 described above and will not be described in detail here.

[0076] refer to Figure 4 、 Figure 7As shown, material three first enters the secondary crushing device 600 alone for pulping and fine crushing, and the pulped material three is transported to the mixing tank 700 for mixing; when material three is mixed in the mixing tank 700, material three in the mixing tank 700 is fed to the secondary crushing device 600 through the third discharge pipe 720, the three-way valve 750, and the second circulation pipe 760 in sequence, and at the same time, the wood pulp processing device 500 adds material four to the secondary crushing device 600, and the secondary crushing device 600 mixes material three with material four and pulps them to form material five, and transports material five in the secondary crushing device 600 to the mixing tank 700 for mixing; when material five in the mixing tank 700 is mixed, material five in the mixing tank 700 is output. In addition, after material three is mixed in the mixing tank 700, it can be first transported to the secondary pulverizing device 600 through the third discharge pipe 720, the three-way valve 750, and the second circulation pipe 760 for pre-filling. When the liquid level in the second feed bin of the secondary pulverizing device 600 reaches the middle-lower liquid level, the pre-filling of the secondary pulverizing device 600 is completed. Then, material four is quantitatively added to the second feed bin of the secondary pulverizing device 600. Material three and material four are mixed and ground to form material five. Material five is then transported to the mixing tank 700 through the second discharge pipe for mixing. In this way, material three is first finely crushed by the secondary pulverizing device 600 and stirred and mixed by the mixing tank 700. Then, material three and material four are mixed and ground to form material five, thereby improving the pulverization effect and the quality of material five.

[0077] Furthermore, if Figure 9As shown, during the process of material three entering the secondary pulverizing device 600 for fine refining, the clearance between the grinding discs of the secondary pulverizing device 600 is reduced. When the liquid level in the second feed bin falls below the lower liquid level, the device is stopped for inspection. When the liquid level in the second feed bin falls below the lower middle liquid level, the opening of the first valve 441 of the first circulation conduit 450 of the primary pulverizing device 400 and the grinding disc speed of the secondary pulverizing device 600 are adjusted. When the liquid level in the second feed bin falls below the upper middle liquid level, the operation is essentially the same as when the liquid level in the second feed bin falls below the lower middle liquid level. When the liquid level in the second feed bin falls below the upper liquid level, the opening of the first valve 441 of the first circulation conduit 450 of the primary pulverizing device 400 and the grinding disc speed of the secondary pulverizing device 600 are adjusted. When the liquid level in the second feed bin rises above the upper liquid level, the device is stopped for inspection. Thus, different operations and adjustments are performed according to the specific situation of the liquid level in the second feed bin to maintain a stable liquid level in the secondary pulverizing device 600, thereby ensuring that the secondary pulverizing device 600 can effectively pulverize material three. In addition, when the first-level crushing device 400 and the second-level crushing device 600 have opposite requirements for the opening degree of the first valve 441 of the first circulation pipe 450 of the first-level crushing device 400, the requirements of the second-level crushing device 600 are met first, thereby reducing the impact of the fluctuation of the grinding wheel speed of the second-level crushing device 600 on the crushing effect, etc.

[0078] Furthermore, if Figure 10 As shown, during the mixing and refining of materials 3 and 4 in the secondary pulverizing device 600 to form material 5, the clearance between the grinding discs of the secondary pulverizing device 600 is increased. When the liquid level in the second feed bin falls below the lower liquid level, the device is stopped for inspection. When the liquid level in the second feed bin falls below the middle-lower liquid level, the speed of the slurry pump 740 in the mixing tank 700 and the speed of the grinding discs of the secondary pulverizing device 600 are adjusted. When the liquid level in the second feed bin falls below the middle-upper liquid level, the operation is essentially the same as when the liquid level in the second feed bin falls below the middle-lower liquid level. When the liquid level in the second feed bin falls below the upper liquid level, the speed of the slurry pump 740 in the mixing tank 700 and the speed of the grinding discs of the secondary pulverizing device 600 are adjusted. When the liquid level in the second feed bin rises above the upper liquid level, the device is stopped for inspection. Thus, different operations and adjustments are performed according to the specific situation of the liquid level in the second feed bin to maintain a stable liquid level in the secondary pulverizing device 600, thereby ensuring that the secondary pulverizing device 600 can better mix, refine and separate materials 3 and 4.

[0079] In some embodiments, as Figure 1As shown, there are multiple secondary pulverizing devices 600. The primary pulverizing device 400 delivers material 3 to each secondary pulverizing device 600 via a first distribution device 800. The wood pulp processing device 500 delivers material 4 to each secondary pulverizing device 600 via a second distribution device 900. The secondary pulverizing devices 600 can be arranged in two groups, each group comprising two secondary pulverizing devices 600, each of which is connected to a mixing tank 700. After the primary pulverizing device 400 has finished feeding one of the secondary pulverizing devices 600 via the first distribution device 800, the first distribution device 800 switches and feeds the remaining secondary pulverizing devices 600 in sequence. This improves production efficiency, among other things.

[0080] Furthermore, if Figure 1 As shown, the first distribution device 800 includes multiple distribution pipes 810, which are connected to the secondary pulverizing devices 600 in a one-to-one correspondence. Each distribution pipe 810 is provided with a third valve 820. Thus, each distribution pipe 810 is controlled by a separate valve, facilitating separate feeding of each secondary pulverizing device 600, which is more efficient, safer, and more reliable.

[0081] Furthermore, if Figure 1 As shown, the second distribution device 900 includes a conveying vibration trough 910, which conveys the material 4 to each secondary crushing device 600 through multiple second conveying mechanisms 920. The conveying vibration trough 910 is provided with a flap discharge port 911 corresponding to each second conveying mechanism 920. The second conveying mechanism 920 can be a belt conveyor, and one second conveying mechanism 920 can feed two secondary crushing devices 600. The wood pulp processing device 500 conveys the material 4 to the conveying vibration trough 910. When the material 4 in the conveying vibration trough 910 is conveyed to the position corresponding to the second conveying mechanism 920, the flap discharge port on the conveying vibration trough 910 opens, allowing the material 4 to be discharged to the second conveying mechanism 920, and then the second conveying mechanism 920 conveys the material 4 to the corresponding secondary crushing device 600. As a result, the structure is more compact, stable, and efficient.

[0082] In some embodiments, the system for preparing thick pulp sheet slurry for heated cigarettes of the present application further includes at least one of an additive processing device (not shown) or an auxiliary material feeding device (not shown). The additive processing device is used to mix a binder and an atomizer to form material 6, and the auxiliary material feeding device is used to add auxiliary materials to a secondary pulverization device 600. The secondary pulverization device 600 is used to mix and grind material 3, material 4, material 6, and / or auxiliary materials to form material 5. In other words, the slurry may contain additives and / or auxiliary materials according to different needs. For example, the additive processing device can mix an adhesive with an atomizer to form material 6, and the secondary pulverizing device 600 can mix and grind materials 3, 4, and 6 to form material 5. The auxiliary material feeding device can add auxiliary materials to the secondary pulverizing device 600, and the secondary pulverizing device 600 can mix and grind materials 3, 4, and the auxiliary materials to form a finished slurry. The additive processing device can mix an adhesive with an atomizer to form material 6, and the auxiliary material feeding device can add auxiliary materials to the secondary pulverizing device 600, and the secondary pulverizing device 600 can mix and grind materials 3, 4, and 6 with the auxiliary materials to form material 5. This can meet different production needs and has a wide range of applications.

[0083] In some embodiments, the system for preparing thick pulp sheet slurry for heated cigarettes of the present application further includes at least one of an additive processing device (not shown) or an auxiliary material feeding device (not shown) and a final mixing device (not shown). The additive processing device is used to mix the binder and the atomizer to form material six, the auxiliary material feeding device is used to add the auxiliary material to the final mixing device, and the final mixing device is used to mix material five with material six and / or the auxiliary material to form a finished slurry.

[0084] That is, additives and / or auxiliary materials can be added to Material 5 according to different needs. For example, the additive processing device can mix the binder and the atomizer to form Material 6, and the final mixing device can mix Materials 5 and 6 to form a finished slurry; the auxiliary material feeding device can add auxiliary materials to the final mixing device, and the final mixing device can mix Materials 5 and 6 to form a finished slurry; the additive processing device can mix the binder and the atomizer to form Material 6, and the auxiliary material feeding device can add auxiliary materials to the final mixing device, and the final mixing device can mix Materials 5, 6, and the auxiliary materials to form a finished slurry. This can meet different production needs and has a wide range of applications.

[0085] Furthermore, the discharge port of the final mixing device is connected to a storage device (not shown) for storing the finished product slurry, thereby facilitating the storage of the prepared finished product slurry.

[0086] In some embodiments, the additive processing device may include: a mixing mechanism (not shown) and a feeding mechanism (not shown). The mixing mechanism is used to mix the adhesive and the atomizer to form material 6, and the feeding mechanism then adds material 6 to the secondary crushing device 600 or the final mixing device. The selected adhesive should be insoluble in the selected atomizer. First, a certain amount of atomizer is added to the mixing mechanism. The mixing mechanism is turned on and the corresponding adhesive is slowly added to form material 6 (suspension); the feeding mechanism can use an offline weighing or weight-reducing feeder, etc. The adhesive should be insoluble in the atomizer. In this way, the adhesive and the atomizer are better mixed to form material 6, thereby improving the quality of material 6.

[0087] See also Figure 5 As shown, according to the method for preparing a thick pulp method sheet slurry for heated cigarettes provided in the embodiment of the present application, the above-mentioned thick pulp method sheet slurry preparation system for heated cigarettes can be applied, and the method includes the following steps:

[0088] The tobacco raw materials are loosened and moistened, air-selected, pre-blended, impurity-removed, shredded, and blended to form a first material, and / or the tobacco fragments are mixed with the crushed powder to form a second material;

[0089] conveying material 1 and / or material 2 and process water to a primary pulverizing device for mixing and wet pulverizing to form material 3;

[0090] The pulp sheet is subjected to wet defibration, solid-liquid separation and pulp loosening to form material four;

[0091] Material three and material four are conveyed to the secondary crushing device for mixing and grinding to form material five.

[0092] Therefore, the preparation method of thick pulp flake slurry for heated cigarettes of the present application adopts a first-level crushing device to first wet-crush the material, and then adopts a second-level crushing device to finely crush and grind the material, thereby wet-crushing the tobacco raw materials, and then realizing the preparation of thick pulp flake slurry for heated cigarettes. The operation is convenient and quick, and can effectively remove impurities from the tobacco raw materials, with good impurity removal effect, thereby improving the purity of the tobacco raw materials, high crushing efficiency, good crushing effect, high tobacco powder yield, and improved quality of the finished slurry. In addition, there is no need for dust removal and dust explosion-proof equipment, and there is no dust at the production site, which reduces the relevant infrastructure and equipment investment as well as maintenance and management work, and facilitates clean production. Some equipment can also use the producer's existing equipment, reducing the producer's equipment idleness and waste, reducing costs, etc.

[0093] In some embodiments, the method for preparing thick pulp sheet slurry for heated cigarettes of the present application also includes: mixing the adhesive and the atomizer to form material six, and then conveying the material three, material four, material six and / or auxiliary materials to a secondary crushing device for mixing and grinding to form material five; or mixing the adhesive and the atomizer to form material six, and then conveying the material five and material six and / or auxiliary materials to a final mixing device for mixing to form a finished slurry.

[0094] That is to say, according to different needs, additives and / or auxiliary materials can be added to the slurry. For example, the binder and the atomizer are mixed to form material 6, and then the materials 3, 4, and 6 are transported to the secondary crushing device for mixing and grinding to form material 5; the materials 3, 4, and the auxiliary materials are transported to the secondary crushing device for mixing and grinding to form material 5; the binder and the atomizer are mixed to form material 6, and then the materials 3, 4, 6, and the auxiliary materials are transported to the secondary crushing device for mixing and grinding to form material 5; the material 5 and the auxiliary materials are transported to the final mixing device for mixing to form the finished slurry; the binder and the atomizer are mixed to form material 6, and then the materials 5 and 6 are transported to the final mixing device for mixing to form the finished slurry; the binder and the atomizer are mixed to form material 6, and then the materials 5, 6, and the auxiliary materials are transported to the final mixing device for mixing to form the finished slurry. In this way, different production needs can be met and the application range is wide.

[0095] In some embodiments, reference Figure 6 As shown, the preparation method of thick pulp thin sheet slurry for heated cigarettes in the present application can be roughly divided into six sections: tobacco raw material processing section, tobacco fragments and tobacco dust processing section, wood pulp preparation section, atomizer and adhesive mixing section, tobacco raw material mixing, crushing and refining section, and final mixing and storage section. Among them, the tobacco strip raw material processing section includes: unpacking raw materials, slicing tobacco strips, loosening and moisture retention, on-site air selection, tobacco strip pre-matching, spectral impurity removal, tobacco strip shredding and tobacco premixing to form material one; the tobacco fragment and tobacco end processing section includes: unpacking raw materials, loosening materials, air conveying and impurity removal, and premixing of tobacco strips to form material two; the wood pulp preparation section includes: pulp board quantitative feeding, pulp board coarse crushing, hydraulic pulping, solid-liquid separation and pulp loosening to form material four; the atomizer and adhesive mixing section includes: quantitative feeding of atomizer, quantitative feeding of adhesive and stirring and mixing to form material six; the tobacco raw material mixing, grinding and pulping section includes: feeding a certain amount of material, quantitative feeding of material two, quantitative feeding of process water, wet grinding to form material three, quantitative feeding of material four, pulping and silk separation, and temporary storage of pulp; the final mixing and storage section includes: quantitative feeding of material five, quantitative feeding of material six, quantitative feeding of auxiliary materials, stirring and mixing to form finished pulp and pulp storage.

[0096] In some embodiments, reference Figure 7As shown, material one and / or material two and process water are transported to a primary pulverizing device for mixing and wet pulverizing to form material three, including:

[0097] Detecting the moisture content of material one and / or material two, and judging whether the wet basis flow rate of material one and / or material two reaches a preset wet basis flow rate according to the moisture content of material one and / or material two; if the wet basis flow rate of material one and / or material two reaches the preset wet basis flow rate, pre-filling of material one and / or material two is completed;

[0098] Close the valve on the discharge pipe of the primary pulverizing device and open the valve on the circulation pipe of the primary pulverizing device, inject process water into the primary pulverizing device, and at the same time, the process water in the primary pulverizing device circulates into the primary pulverizing device through the discharge pipe and the circulation pipe in sequence. If the liquid level in the primary pulverizing device reaches the pre-filling level, the pre-filling of the primary pulverizing device is completed;

[0099] After the pre-filling of material one and / or material two and the primary crushing device is completed, material one and / or material and process water are transported to the primary crushing device for mixing and wet crushing to form material three. At the same time, the valve on the discharge pipe is opened and the opening of the valve on the circulation pipe is reduced, and material three in the primary crushing device is output to the secondary crushing device through the discharge pipe.

[0100] That is to say, the material one and / or material two are pre-filled and the primary pulverizing device is pre-filled first, and then the material one and / or material and process water are transported to the primary pulverizing device for mixing and wet pulverization to form the material three. In this way, the material three is better formed, the quality of the material three is improved, and the subsequent processing of the material is convenient. In addition, after the material one and / or material two and the primary pulverizing device are pre-filled, since the material one and / or material two are a certain distance away from the feed port of the first feed bin, in order to ensure that the material one and / or material two are fed to the primary pulverizing device synchronously with the process water, the process water can be delayed for a certain time. When the material one and / or material two are transported to the feed port of the first feed bin, the material one and / or material two are fed to the first feed bin of the primary pulverizing device synchronously with the process water.

[0101] In some embodiments, material 1 and / or material 2 and process water are conveyed to the primary pulverization for mixing and wet pulverization to form material 3, and the process further includes: detecting the moisture content of material 1 and / or material 2, adjusting the amount of process water supplied based on the moisture content of material 1 and / or material 2, and controlling the moisture content of material 3 to be between 70% and 90%. This ensures the quality of material 3 and facilitates better preparation of subsequent materials.

[0102] In some embodiments, material 1 and / or material 2, along with process water, are conveyed to a primary pulverizer for mixing and wet pulverization to form material 3, further comprising: controlling the particle size of material 3 to be between 100 and 300 mesh by adjusting the grinding disc gap of the primary pulverizer. This ensures the quality of material 3 and facilitates better preparation of subsequent materials.

[0103] In some embodiments, reference Figure 8 As shown, material one and / or material two and process water are transported to the primary pulverizing device for mixing and wet pulverizing to form material three, and also includes: controlling the liquid level in the primary pulverizing device by adjusting the grinding disc speed of the primary pulverizing device, the opening of the valve on the circulation pipeline, the feeding speed of material one and / or material two and process water.

[0104] During the preparation of material three, the primary pulverizing device is stopped for inspection when the liquid level in the first feed bin is lower than the lower liquid level; when the liquid level in the first feed bin is lower than the middle-lower liquid level, the opening of the first valve of the first circulation pipeline, the rotation speed of the grinding disc of the primary pulverizing device, the feeding speed of material one and / or material two, and process water are adjusted; when the liquid level in the first feed bin is lower than the middle-upper liquid level, the operation is basically the same as when the liquid level in the first feed bin is lower than the middle-lower liquid level; when the liquid level in the first feed bin is lower than the upper liquid level, the opening of the first valve of the first circulation pipeline, the rotation speed of the grinding disc of the primary pulverizing device, the feeding speed of material one and / or material two, and process water are adjusted; when the liquid level in the first feed bin is higher than the upper liquid level, the device is stopped for inspection. Thus, according to the specific situation of the liquid level in the first feed bin, different operations and adjustments are performed to maintain the liquid level in the primary pulverizing device stable, thereby ensuring that the primary pulverizing device performs pulverization better, etc., and preventing factors such as fluctuations in process water flow during the production process from causing liquid overflow due to excessively high liquid level or material shortage in the pulverizing device due to excessively low liquid level.

[0105] In some embodiments, reference Figure 7 As shown, material three and material four are conveyed to a secondary crushing device for mixing and grinding to form material five, including:

[0106] First, the material 3 is transported to the secondary crushing device for refining, and the refining material 3 is transported to the mixing tank for mixing;

[0107] After material three is mixed in the mixing tank, material four and material three in the mixing tank are transported to the secondary crushing device for mixing and grinding to form material five, and material five in the secondary crushing device is transported to the mixing tank for mixing. After material five in the mixing tank is mixed, material five in the mixing tank is output.

[0108] That is to say, material three is first finely crushed by a secondary crushing device and stirred and mixed by a mixing tank, and then material three is mixed with material four and ground into material five, thereby achieving better crushing effect and improving the quality of material five.

[0109] In some embodiments, when the material is transported to the secondary pulverizing device for refining, the gap between the grinding discs of the secondary pulverizing device is reduced, and the liquid level in the secondary pulverizing device is controlled by adjusting the grinding disc speed of the secondary pulverizing device and the opening of the valve on the circulation pipe. Specifically, Figure 9 As shown, when material three enters the secondary pulverizing device alone for fine refining, the gap between the grinding discs of the secondary pulverizing device is reduced. When the liquid level in the second feed bin is lower than the lower liquid level, the device is stopped for inspection. When the liquid level in the second feed bin is lower than the lower-middle liquid level, the opening of the first valve of the first circulation pipe of the primary pulverizing device and the speed of the grinding disc of the secondary pulverizing device are adjusted. When the liquid level in the second feed bin is lower than the upper-middle liquid level, the operation is basically the same as when the liquid level in the second feed bin is lower than the lower-middle liquid level. When the liquid level in the second feed bin is lower than the upper liquid level, the opening of the first valve of the first circulation pipe of the primary pulverizing device and the speed of the grinding disc of the secondary pulverizing device are adjusted. When the liquid level in the second feed bin is higher than the upper liquid level, the device is stopped for inspection. Thus, different operations and adjustments are performed according to the specific situation of the liquid level in the second feed bin to maintain a stable liquid level in the secondary pulverizing device, thereby ensuring that the secondary pulverizing device can better pulverize material three. In addition, when the first-stage crushing device and the second-stage crushing device have opposite requirements for the opening degree of the first valve of the first circulation pipe of the first-stage crushing device, the requirements of the second-stage crushing device are met first, thereby reducing the impact of the fluctuation of the grinding wheel speed of the second-stage crushing device on the crushing effect.

[0110] In some embodiments, when the third material and the fourth material are transported to the secondary pulverizing device for mixing and refining, the gap between the grinding discs of the secondary pulverizing device is increased, and the liquid level in the secondary pulverizing device is controlled by adjusting the grinding disc speed of the secondary pulverizing device and the feeding speed of the third material from the mixing tank to the secondary pulverizing device. Specifically, Figure 10As shown, during the process of mixing and refining material three and material four in the secondary pulverizing device to form material five, the gap between the grinding discs of the secondary pulverizing device is increased. When the liquid level in the second feed bin is lower than the lower liquid level, the device is stopped for inspection. When the liquid level in the second feed bin is lower than the middle-lower liquid level, the speed of the slurry pump in the mixing tank and the speed of the grinding discs of the secondary pulverizing device are adjusted. When the liquid level in the second feed bin is lower than the middle-upper liquid level, the operation is basically the same as when the liquid level in the second feed bin is lower than the middle-lower liquid level. When the liquid level in the second feed bin is lower than the upper liquid level, the speed of the slurry pump in the mixing tank and the speed of the grinding discs of the secondary pulverizing device are adjusted. When the liquid level in the second feed bin is higher than the upper liquid level, the device is stopped for inspection. Thus, different operations and adjustments are performed according to the specific situation of the liquid level in the second feed bin to maintain a stable liquid level in the secondary pulverizing device, thereby ensuring that the secondary pulverizing device can better mix, refine and separate material three and material four.

[0111] In some embodiments, the pulp sheet is crushed, solid-liquid separated, dehydrated, and loosened to form the material 4, further comprising: controlling the moisture content of the material 4 to be less than 80%. This ensures the quality of the material 4 and facilitates better preparation of subsequent materials.
