Description

Technical Field

[0001] The present invention relates to the technical field of drying and heating, and more particularly to a layered new energy hot air circulation device for a drying barn. Background Art

[0002] The layered hot air circulation device of the new energy drying barn is designed in layers, so the hot air can act more specifically on the materials in different layers. During the tobacco drying process, the thickness and quantity of tobacco leaves placed in different layers may be different. The layered hot air circulation device can adjust the wind speed, temperature and flow direction of the hot air according to the actual situation of each layer, so that each layer of material can be heated evenly, thereby improving the drying quality.

[0003] Patent publication number CN113834311A discloses a dehumidification device and control method for a small experimental tobacco curing room. This technology activates electric shutters and a heat exhaust valve when the heat pump unit is in dehumidification mode. This system, coupled with fresh air intake, creates a small exhaust route within the heat pump unit. This allows heat generated by the condenser to be promptly discharged through the heat exhaust valve, reducing the amount of heat entering the tobacco loading chamber and maintaining a more stable curing temperature within the chamber, thereby improving tobacco curing quality. However, this patent has the following drawbacks.

[0004] New energy curing rooms are powered by clean energy for heating, and use hot air circulation to continuously heat and dry the material tobacco leaves. However, the material tobacco leaves are prone to close contact when stacked, and a large number of material tobacco leaves will form piles when piled together. It is difficult to ensure that horizontal, vertical and side vertical gaps will spontaneously form in the piles of material tobacco leaves. The material tobacco leaves inside have low heating efficiency, and it is difficult to achieve large-area interval heating and drying. This makes it difficult to fully dry and heat, and the heating and drying efficiency of the material tobacco leaves is greatly reduced, and the drying time is greatly extended. Due to the slow drying process, the curing room needs to run for a long time to maintain suitable drying conditions, and energy consumption increases accordingly. This not only increases the drying cost of the material tobacco leaves, but also has poor energy saving and consumption reduction. Summary of the Invention

[0027] The technical effects and advantages of the present invention are as follows:

[0028] 1. The present invention adopts a horizontal interval drying component. The horizontal interval drying design has significant advantages. A large amount of tobacco leaves are dispersed to both sides of the triangular guide frame along the guide strips. The triangular guide frame forms a triangular horizontal interval, allowing the tobacco leaves to initially form a triangular dispersion. Then the tobacco leaves move along the side of the triangular guide frame to the interval horizontal frame. The interval horizontal frame realizes horizontal drying intervals, forming horizontal drying gaps of the interval grooves. The triangular holes bring horizontal triangular intervals. This multi-level and multi-form horizontal interval allows hot air to fully and evenly contact the tobacco leaves, avoiding local excessive or insufficient drying, greatly improving the drying quality, and at the same time accelerating the moisture dissipation rate, shortening the drying time, improving production efficiency, reducing energy waste, and reducing drying costs, achieving the dual advantages of high efficiency energy saving and quality improvement.

[0029] 2. The present invention vertically spaces the material, and the tips of a large number of tobacco leaves are squeezed close to the vertical partition plate, and then diffused outward along the outer wall of the arc sleeve. The pillars support the vertical partition plate. This stable support structure ensures that the vertical partition plate and the vertical partition plate can accurately place the tobacco leaves according to the vertical spacing distance, which can avoid the accumulation of tobacco leaves to produce specified vertical spacing gaps, so that hot air can fully penetrate the vertical spacing gaps of each layer of tobacco leaves, achieving uniform drying, improving drying quality, and also accelerating the drying speed, improving production efficiency, reducing energy consumption, and reducing drying costs.

[0030] 3. The present invention utilizes a side vertical spacing drying group. The side vertical spacing placement design has unique advantages. A large amount of tobacco leaves on the side are inclined along the guide column to guide the outer wall of the side spacing bar. A large amount of tobacco leaves on the side will produce vertical spacing drying gaps, which make the tobacco leaves transition to the side guide plate and then to the outer wall of the side spacing frame, forming a multi-point vertical spacing placement. The side spacing bars, side guide plates, the drying gaps inside the side spacing frame, and the side guide plates and side spacing bars all have large gaps, ensuring that hot air fully penetrates the large amount of tobacco leaves on the side, achieving uniform and efficient drying, improving drying quality and efficiency, reducing energy consumption, and reducing drying costs.

[0031] In summary, through the interaction of the above-mentioned multiple effects, first, a large amount of tobacco leaves pass through the arc sleeve and the vertical partition plate to produce a specified vertical spacing gap, and at the same time form a horizontal drying gap of the spacing groove. The triangular holes also bring about a horizontal triangular spacing. At the same time, through the side spacing strips, side guide plates, the drying gap inside the side spacing frame, and the large gaps between the side guide plates and the side spacing strips, a large amount of tobacco leaves on the side can produce large drying and heating gaps in multiple parts. In summary, the hot air can achieve sufficient drying contact in the horizontal spacing gaps, vertical spacing gaps, and lateral vertical spacing gaps for a large amount of tobacco leaves, achieving the dual advantages of high efficiency, energy saving, and improved drying quality.

DETAILED DESCRIPTION

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0043] As attached Figure 1 - Attachment Figure 9 A layered new energy baking room hot air circulation device is shown. The layered new energy baking room hot air circulation device is provided with a horizontal spacing drying component, a vertical spacing material and a side vertical spacing drying component. The arrangement of each component enables the hot air to fully dry and contact a large amount of tobacco leaves in the horizontal spacing gaps, vertical spacing gaps and side vertical spacing gaps, thereby achieving the dual advantages of high efficiency and energy saving and improved drying quality. The specific structural arrangement of each component is as follows.

[0044] In this embodiment, as shown in the attached Figure 1 - Attachment Figure 3As shown, the inner wall of the drying box 1 is fixedly connected to two perforated frames 2. The upper surface of each perforated frame 2 is equipped with multiple sets of horizontal spacer drying assemblies. These horizontal spacer drying assemblies include: a spacer horizontal frame 3 fixed to the upper surface of the perforated frame 2, with a spacer slot 4 defined in its inner wall and multiple horizontal holes 5 defined in its outer wall; a triangular guide frame 6 mounted on one side of the spacer horizontal frame 3 and fixedly connected to the spacer horizontal frame 3, with a triangular hole 7 defined within it, and multiple frame slots 8 defined within the triangular hole 7; a guide bar 9 fixed to a corner of the outer wall of the triangular guide frame 6, and multiple resistance heating rods 11 fixedly mounted on the inner wall of the drying box 1 near its bottom. A vertical spacer drying assembly is provided on one side of the guide bar 9 for vertically spacing materials. Side vertical spacer drying assemblies are provided on both sides of the triangular guide frame 6. The multiple horizontal holes 5 are arranged equidistantly from top to bottom, and the cross-section of the horizontal holes 5 is concave. The cross-section of the triangular hole 7 is triangular, and multiple frame slots 8 are arranged equidistantly from top to bottom. This allows a large amount of raw tobacco leaves to be dispersed along the guide strips 9 to both sides of the triangular guide frame 6. The triangular guide frame 6 allows a large amount of raw tobacco leaves to form triangular transverse spacing and dispersed drying gaps. After that, a large amount of raw tobacco leaves move along the side of the triangular guide frame 6 to the side of the spacing horizontal frame 3. The spacing horizontal frame 3 realizes transverse drying intervals, forming rectangular transverse drying gaps of the spacing slots 4. In addition, the triangular hole 7 also creates transverse triangular spacing and drying gaps for a large amount of raw tobacco leaves. The multiple spacing gaps allow hot air to fully penetrate a large amount of raw tobacco leaves, achieving heat exchange contact treatment over a large area, accelerating moisture loss, and significantly shortening the drying time. Due to the improved drying efficiency, the operating time of the drying room is reduced, energy consumption is reduced, and energy saving and environmental protection are higher.

[0045] In this embodiment, as shown in the attached Figure 3 - Attachment Figure 4As shown, the vertical spacer drying assembly includes: a groove bar 10, which is fixedly connected to the outer wall of the guide bar 9, and the upper surface of the groove bar 10 is fixedly connected to the arc bar 12; a vertical spacer disk 13, which is fixedly installed on the top of the arc bar 12, and the outer wall of the vertical spacer disk 13 is wrapped and fixedly connected with an arc sleeve 14, and the interior of the vertical spacer disk 13 is provided with a plurality of inclined holes 15; a pillar 16, which is installed on the lower inclined surface of the vertical spacer disk 13, and the pillar 16 is used to support the vertical spacer disk 13, and the bottom end of the pillar 16 is fixedly installed with a vertical spacer plate 17, and the interior of the vertical spacer plate 17 is provided with a plurality of arc holes 18, and the plurality of arc holes 18 are arranged in sequence and equidistantly from front to back. A plurality of inclined holes 15 are arranged in a circumferentially equidistant distribution, and a gap is provided between the vertical spacer disk 13 and the vertical spacer plate 17. The vertical cross-section of the arc hole 18 is in the shape of an arc, so that the tips of a large number of material tobacco leaves can approach and squeeze the vertical spacer plate 17, and diffuse downward in an arc through the vertical spacer plate 17, and then diffuse outward in an arc along the outer wall of the arc sleeve 14. The vertical spacer disk 13 can support the arc sleeve 14 to diffuse a large number of material tobacco leaves. At the same time, the vertical spacer disk 13 also supports the vertical spacer plate 17 through the support 16. In this way, with the help of the gap between the vertical spacer plate 17 and the vertical spacer disk 13, a large number of material tobacco leaves can be placed according to the vertical spacing distance, so that a large number of material tobacco leaves can be placed vertically at intervals to avoid accumulation. Secondly, it can reasonably utilize the baking room space, increase the placement amount of a large number of material tobacco leaves, and improve production efficiency.

[0046] In this embodiment, as shown in the attached Figure 5 - Attachment Figure 6As shown, the side vertical spacing drying assembly includes: a side spacer 19, which is fixed on one side surface of the triangular guide frame 6, and the inner wall of the side spacer 19 is provided with a plurality of inclined grooves 20, and one end of the side spacer 19 is fixedly connected to a guide column 21; a connecting column 22, which is fixedly installed on the inner wall of the side spacer 19, and the outer wall of the side spacer 19 is fixedly provided with a sleeve 23, and one end of the sleeve 23 is fixedly connected to a side guide plate 24; a side spacer frame 25, which is installed on one side of the side guide plate 24, and the side guide plate 24 is fixedly connected to the side spacer frame 25, and the side spacer frame 25 is fixedly connected to the spacing cross frame 3, and a plurality of guide holes 26 are provided inside the side spacer frame 25. A plurality of inclined grooves 20 are arranged in equal intervals from front to back, and the vertical cross-section of the side guide plate 24 is in the shape of a circular arc, so that a large number of tobacco leaves on the side can be inclinedly guided along the guide column 21 to the outer wall of the side spacer 19, and supported by the connecting column 22 and the sleeve strip 23. The large number of tobacco leaves on the side transition to the position of the outer wall of the side guide plate 24, so that the large number of tobacco leaves on the side move to the outer wall of the side spacer frame 25. In this way, the side spacer 19, the side guide plate 24, and the side spacer frame 25 can provide a larger interval drying gap, as well as a larger drying gap between the side guide plate 24 and the side spacer 19, so that a large number of tobacco leaves on the side can be placed vertically at multiple points to ensure that the tobacco leaves are heated evenly. Secondly, it has high drying efficiency, and reasonable spacing and larger gaps are conducive to the circulation of hot air, which speeds up the drying speed and shortens the time.

[0047] In this embodiment, as shown in the attached Figure 7 - Attachment Figure 9As shown, a temperature sensor 27 is installed between the two resistance heating rods 11 and is fixedly connected to the drying oven 1. An air outlet pipe 28 is provided on one side of the temperature sensor 27 and is fixedly connected to the drying oven 1. A circulating fan 29 is installed at the top of the air outlet pipe 28, and an air inlet pipe 30 is fixedly connected to the input end of the circulating fan 29. A top transparent plate 31 is fixedly installed at the bottom end of the air inlet pipe 30, and the lower surface of the top transparent plate 31 is coated with a layer of black chromium oxide. Side transparent plates 32 are embedded on both sides of the inner wall of the drying oven 1, and each side transparent plate 32 is fixedly connected to the interior of a plurality of heat-conducting bevels 33. The multiple heat-conducting bevels 33 are arranged equidistantly from top to bottom, and the vertical cross-section of the heat-conducting bevels 33 is rectangular. The outer wall of the drying box 1 is hinged with a cover door 34, and a controller 35 is fixedly installed on one side of the cover door 34. The resistance heating rod 11 and the temperature sensor 27 are both electrically connected to the controller 35; the circulating fan 29 is electrically connected to the controller 35 so that when the weather is clear, sunlight passes through the top transparent plate 31, and the black chromium oxide coating on the lower surface of the top transparent plate 31 absorbs heat energy and conducts it into the drying box 1 to preheat the tobacco leaves. The side transparent plates 32 and the heat-conducting inclined plates 33 also assist in absorbing solar heat energy to achieve heat conduction. Then the controller 35 turns on the resistance heating rod 11 for heating and starts the circulating fan 29 to circulate air in the drying box 1. The hot air passes through the multiple drying gaps of the spacing grooves 4, horizontal holes 5, triangular holes 7, frame grooves 8, and inclined holes 15 to dry the tobacco leaves horizontally, vertically, and laterally. Solar energy preheating can be used to reduce energy consumption. The resistance heating and the circulating fan cooperate to improve drying efficiency. Secondly, the multi-path spacing diversion ensures that the hot air is in full contact with the tobacco leaves and is dried evenly.

[0048] The method of using the layered new energy hot air circulation device for the baking room of the present invention is as follows:

[0049] Step 1, during vertical interval drying, open the cover door 34, and a large amount of material tobacco can be inserted into the upper surface of the perforated rack 2. At the same time, a large amount of material tobacco leaf tips are squeezed close to the vertical partition plate 17, and a large amount of material tobacco leaves are dispersed downward along the vertical partition plate 17 and diffused outward along the outer wall of the arc sleeve 14. At the same time, the groove bar 10 supports the arc bar 12, the arc bar 12 supports the vertical spacer disk 13, and the vertical spacer disk 13 supports the arc sleeve 14. The arc sleeve 14 diffuses the material tobacco leaves outward. At the same time, the vertical spacer disk 13 supports the pillar 16, and the pillar 16 supports the vertical spacer plate 17. A large amount of material tobacco leaves can be placed according to the vertical spacing distance through the vertical spacer plate 17 and the vertical spacer disk 13.

[0050] Step 2. During the horizontal interval drying, a large number of material tobacco leaves are dispersed to the two sides of the triangular guide frame 6 along the guide strip 9. The triangular guide frame 6 forms a triangular horizontal interval dispersion drying gap for the large number of material tobacco leaves, and a large number of material tobacco leaves move along the side of the triangular guide frame 6 to the side of the interval horizontal frame 3. The interval horizontal frame 3 can realize horizontal drying intervals for a large number of material tobacco leaves. After the interval, a horizontal drying gap of the interval groove 4 is formed, and the triangular hole 7 can form a horizontal triangular interval drying gap for a large number of material tobacco leaves.

[0051] Step 3: During vertical side drying, a large amount of tobacco leaves will be diverted along the guide column 21 to the outer wall of the side spacer 19. The side spacer 19 can create vertical drying gaps for the large amount of tobacco leaves. At the same time, the triangular guide frame 6 supports the side spacer 19, the side spacer 19 supports the connecting column 22, the connecting column 22 supports the sleeve 23, and the sleeve 23 supports the side guide plate 24. In this way, the large amount of tobacco leaves will transition along the side spacer 19 to the outer wall of the side guide plate 24, and then along the side guide plate 24 to the outer wall of the side partition frame 25. In this way, the drying gaps formed inside the side spacer 19, the drying gaps formed inside the side guide plate 24, and the drying gaps formed inside the side partition frame 25 can all achieve vertical spacing of a large amount of tobacco leaves at multiple points on the side. At the same time, a larger drying gap is also formed between the side guide plate 24 and the side spacer 19. After placing a large amount of tobacco leaves on the two-layer perforated rack 2 , the upper cover door 34 is closed, and the cover door 34 and the drying box 1 are sealed, so that a large amount of tobacco leaves are layered inside the drying box 1 .

[0052] Step 4: During the heating and drying process, when the sky is clear and the sun is shining, the top transparent plate 31 is illuminated by sunlight. The bottom surface of the top transparent plate 31 is coated with a black chromium oxide coating. This allows light to pass through the top transparent plate 31, allowing the black chromium oxide coating to absorb a large amount of solar heat energy, which is then conducted into the drying box 1. This allows a large amount of tobacco leaves to be preheated and dried, saving preheating energy. Simultaneously, the side transparent plates 32 on both sides are placed transparently, and heat is conducted through the multiple heat-conducting bevels 33 on the side transparent plates 32. This heat conduction achieves a preheating operation for the large amount of tobacco leaves. In this way, a large amount of tobacco leaves inside the drying box 1 can be preheated by solar heat.

[0053] Then, the controller 35 turns on the multiple resistance heating rods 11, and the multiple resistance heating rods 11 heat the inside of the drying box 1. The temperature is sensed by the temperature sensor 27, and the circulation fan 29 is started by the controller 35. The circulation fan 29 causes the outlet pipe 28 to transport the air inside the drying box 1 to the inside of the air inlet pipe 30, and enters the drying box 1 along the top transparent plate 31 through the air inlet pipe 30. In this way, the hot air is diverted along the inside of the spacing groove 4 and the inside of the multiple horizontal holes 5. At the same time, a large amount of material tobacco leaves are diverted through the triangular holes 7 and the inside of the multiple frame grooves 8. At the same time, the hot air is discharged downward along the multiple inclined holes 15, and is also diverted along the gap between the vertical spacing disk 13 and the vertical spacing plate 17. And it can be diverted along the multiple arc holes 18 on the vertical partition plate 17, and it can also be diverted along the gaps inside the inclined groove 20 and the side spacer 19. At the same time, it can be diverted along the gaps between the side guide plate 24 and the side spacer 19, and through multiple guide holes 26. In this way, hot air will continue to enter the inside of the air outlet pipe 28, and the hot air can fully dry and contact a large amount of tobacco leaves in the horizontal interval gaps, vertical interval gaps, and lateral vertical interval gaps until the temperature value sensed by the temperature sensor 27 is transmitted to the controller 35. If the temperature sensor value exceeds the temperature value set by the controller 35, the controller 35 will turn off the multiple resistance heating rods 11 and maintain the specified temperature for cyclic drying.
