Description

Technical Field

[0001] The invention relates to the technical field of drying, in particular to a multi-layer mesh belt type lily drying device. Background Art

[0002] Lily is a common food and medicine, rich in phenolic acid glycerides, propionate derivatives, phenolic acid glycosides, phenolic acid glyceride glycosides, steroidal glycosides, steroidal alkaloids, trace elements, starch, protein, fat and other ingredients. It has the effects of nourishing yin and moistening the lungs, clearing the heart and calming the mind. It is mainly used to treat yin deficiency and dry cough, cough with blood due to fatigue, insomnia and palpitations due to yin deficiency and heat, and lily disease of heart and lung yin deficiency and internal heat. Lily is rich in nutrients, and fresh lily is extremely easy to deteriorate at room temperature, so fresh lily is often dried to improve the medicinal value and storage and transportation capacity of lily.

[0003] Mesh-belt dryers are often the first choice for drying lilies due to their large drying capacity and continuous operation. However, existing mesh-belt dryers heat and blow air through the mesh belt in the drying area, allowing hot air to pass through the layer of accumulated lilies to take away moisture for drying. One-way blowing will cause uneven heating of the lilies. At the same time, large-scale blowing will also cause a large amount of hot air to stay in the lily layer for too short a time and directly dissipate, causing heat energy loss. The quality of lilies varies greatly, and dried lilies often need to be further screened to remove defective products in order to improve product quality. Traditional mesh-belt dryers require additional screening machines for screening, which increases the investment cost and production cycle of the equipment. Summary of the invention

[0047] The embodiment of the present invention provides a multi-layer mesh belt type lily drying device, comprising a device body 1, a driving mechanism 2, an air supply component 3 and a drying box 4.

[0048] See also Figures 1 to 4 and Fig. 9The device body 1 includes a device box 13, a feed port 12 is provided at one end of the top of the device box 13, a plurality of exhaust holes 11 are arranged at intervals on the top of the device box 13, a discharge port 14 is provided on the front end face of the device box 13 away from the feed port 12, a slag collecting box 16 is provided at the bottom of the inner cavity of the device box 13, and the slag collecting box 16 is arranged on the same side as the feed port 12, a driving ring 15 is fixedly connected to the side wall of the device box 13, and a driving mechanism 2 includes a driving motor 21, and the driving motor 21 is installed on the front end face of the device box 13, and the output end of the driving motor 21 passes through the device box 13 and is fixedly connected to a roller shaft, and there are two groups of roller shafts and are rotatably connected to the inner wall of the device box 13, and the outer walls of the two groups of roller shafts are transmission-connected to a conveyor belt 23, and a plurality of groups of mounting plates 22 are fixedly connected to the outer side of the conveyor belt 23 at intervals, and the mounting plate 2 A driving assembly 24 is installed on the side wall of the conveyor belt 23, and a plurality of driving rails 25 are arranged at intervals along the conveying direction of the conveyor belt 23. A avoiding assembly 26 is arranged in parallel with the driving rails 25. The drying box 4 is installed in the adjacent area of ​​the two groups of mounting plates 22 and is slidably connected with the avoiding assembly 26. When the driving motor 21 is working, the driving assembly 24 drives the drying box 4 to reciprocate outside the conveyor belt 23 to screen the lilies inside the drying box 4. The air supply assembly 3 includes a main air supply pipe 32, which is located in the inner area of ​​the conveyor belt 23, and the front end of the main air supply pipe 32 passes through the front end surface of the device box 13 and is fixedly connected with a connecting end. A plurality of air supply pipes 31 are arranged at intervals on the outer wall of the main air supply pipe 32, and the air supply pipe 31 is connected with the lower end of the drying box 4 to directionally dry the lilies inside the drying box 4.

[0049] It is understandable that the trajectory of the drive ring 15 is the same as the moving trajectory of the drive assembly 24 . When the drive assembly 24 follows the conveyor belt 23 for transportation, the front end of the drive assembly 24 is always in contact with the inner side of the drive ring 15 .

[0050] In addition, the driving rail 25 at both ends of the roller shaft can bend and deform along with the conveyor belt 23 . At the same time, the driving rail 25 has a certain supporting force to limit the moving trajectory of the drying box 4 .

[0051] See also Figure 5 and Figure 6 The driving rail 25 includes a rail 251, a tooth groove 252 is provided on the side of the rail 251 close to the avoidance component 26, and a limiting groove 253 is provided at the lower end of the same side of the tooth groove 252. The avoidance component 26 includes a first upper sealing plate 261 and a first lower sealing plate 262, and the first lower sealing plate 262 and the first lower sealing plate 262 are partially overlapped.

[0052] Specifically, a first through groove is formed on the upper end surface of the conveyor belt 23, and a first upper sealing plate 261 and a first lower sealing plate 262 are respectively arranged on both sides of the first through groove, and the first upper sealing plate 261 and the first lower sealing plate 262 are overlapped and arranged away from the edge of the first through groove.

[0053] It is understandable that the first upper sealing plate 261 and the first lower sealing plate 262 are both made of elastic materials and have a small friction coefficient on the adjacent sides, so that the first upper sealing plate 261 and the first lower sealing plate 262 will fit each other when close to each other and will separate when subjected to external force.

[0054] See also Figure 7 and Figure 8 The driving assembly 24 includes a driving shaft 242, which is rotatably connected to the side wall of the mounting plate 22 through a support rod. The driving shaft 242 is fixedly connected to a gear 241 on the side close to the driving rail 25, and the driving shaft 242 is fixedly connected to a driving wheel 243 on the side away from the driving rail 25. The driving ring 15 includes two groups of horizontal driving strips 151 and two groups of curved driving strips 153. The two groups of horizontal driving strips 151 are fixedly connected by two groups of curved driving strips 153 to form a playground runway shape. The two groups of horizontal driving strips 151 are fixedly connected to form a playground runway shape. A driving tooth groove 152 is provided on one side adjacent to 51, and the outer wall of the gear 241 is meshed with the driving tooth groove 152. The gear 241 moving with the mounting plate 22 is meshed with the driving tooth groove 152 in the horizontal section, driving the driving wheel 243 to rotate, so that the drying box 4 moves back and forth along the driving rail 25 and moves synchronously with the conveyor belt 23, and fits with the curved driving bar 153 in the curved section. At this time, the driving wheel 243 remains stationary, and the drying box 4 moves synchronously with the conveyor belt 23 outside the driving rail 25.

[0055] It should be added that the mounting plate 22 includes a plate body 221 , and a slag leakage groove 222 is provided on one side of the plate body 221 close to the conveyor belt 23 . The sieved residue passes through the slag leakage groove 222 and is finally collected into the slag collecting box 16 .

[0056] See also Fig. 9 and Fig.10 The air supply pipe 31 includes a tube body 311, which is a playground runway shape and hollow inside. The hot air flow is transported to the inside of each group of tube bodies 311 through the main air supply pipe 32. The side wall of the tube body 311 close to the conveyor belt 23 is overlapped with a second lower sealing plate 312 and a second upper sealing plate 313.

[0057] Specifically, a second through groove is provided on the outer wall of the tube body 311, and the second lower sealing plate 312 and the second upper sealing plate 313 are fixedly connected on both sides of the second through groove respectively. The second lower sealing plate 312 and the second upper sealing plate 313 are made of elastic materials and the second lower sealing plate 312 and the second upper sealing plate 313 are adhered when the adjacent sides are close to each other, and are separated under the action of external force.

[0058] See also Figure 11 to Figure 12The drying box 4 includes a box body 41, and a plurality of groups of air-equalizing components 42 are installed at intervals at the bottom of the inner cavity of the box body 41. The lower end of the air-equalizing component 42 passes through the avoidance component 26 and is communicated with the inside of the pipe body 311. The hot air flow is transported to the inside of the lily layer in the box body 41 through the air-equalizing component 42 to dry the lilies in layers. The box body 41 includes a fixed box body 411, and the outer wall of the fixed box body 411 is hingedly connected to a driving plate 412. The end of the driving plate 412 away from the fixed box body 411 is hingedly connected to the eccentric position of the driving wheel 243 away from the driving shaft 242. When the driving shaft 242 rotates, the driving plate 412 is connected to the eccentric position of the driving wheel 243 away from the driving shaft 242. The movable plate 412 pushes the fixed box 411 to move back and forth, and a movable mesh plate 414 is slidably connected to the side of the inner cavity of the fixed box 411 away from the driving plate 412. A through groove 415 is provided on the front end face of the fixed box 411 close to the side of the movable mesh plate 414. When the movable mesh plate 414 moves to be in the same straight line with the through groove 415, the movable mesh plate 414 can be pulled out from the through groove 415 to pour out the dried lilies in the fixed box 411. A mounting plate 413 is provided at the bottom of the inner cavity of the fixed box 411, and the upper end of the air equalization component 42 passes through the mounting plate 413 and extends into the fixed box 411.

[0059] Specifically, the amount of lilies filled in the fixed box 411 does not exceed two-thirds of the height of the inner cavity of the fixed box 411. The fixed box 411 moves with the conveyor belt 23. When the movable mesh plate 414 is located at the bottom, the lilies in the fixed box 411 push the movable mesh plate 414 to slide in the fixed box 411. When the lilies are completely dried, the movable mesh plate 414 is pushed by the dried lilies to be in the same line as the through groove 415. At this time, the movable mesh plate 414 can be pulled out and the dried lilies can be poured out.

[0060] See also Fig.13 In order to prevent the movable mesh plate 414 from falling out of the through slot 415 when moving, the movable mesh plate 414 includes a mesh plate body 4141, and two groups of elastic protrusions 4143 are arranged at intervals on both sides of the mesh plate body 4141 near one end of the through slot 415. The elastic protrusions 4143 limit the movable mesh plate 414 inside the fixed box 411 to prevent the movable mesh plate 414 from sliding out of the through slot 415 during movement. Grooves 4142 are symmetrically arranged on the same side of the mesh plate body 4141 and the elastic protrusions 4143. When the mesh plate body 4141 and the through slot 415 are located in the same straight line, the mesh plate body 4141 can be pulled out of the through slot 415 by holding the groove 4142.

[0061] It should be noted that the elastic protrusions 4143 are elastic protrusions, the thickness of the mesh plate body 4141 does not exceed the inner width of the through slot 415 , and the sum of the thickness of the two groups of elastic protrusions 4143 and the mesh plate body 4141 is greater than the inner width of the through slot 415 .

[0062] See also Fig.14 and Fig.15The air equalization component 42 includes two forms: an air equalization component 42A and an air equalization component 42B. The air equalization component 42A and the air equalization component 42B are arranged alternately. The air equalization component 42 includes a main air duct 421. The outer wall of the main air duct 421 is fixedly connected with a gear sleeve 423. The outer wall of the gear sleeve 423 is rotatably connected with an L-shaped mounting block 422. The top of the L-shaped mounting block 422 is fixedly connected to the lower end surface of the mounting plate 413. The gear sleeve 423 is partially located outside the L-shaped mounting block 422 and meshes with the gear of the tooth groove 252. When the fixed box 411 moves back and forth, the main air duct 421 reciprocates through the tooth groove 252 meshing with the gear sleeve 423. The side wall of the L-shaped mounting block 422 is slidably connected in the limiting groove 253 to prevent the L-shaped mounting block 422 from falling off the track 251 during movement. The main air duct 421 is located in the inner cavity of the fixed box 411 and is provided with two groups of air ducts 425 on the outer wall. The outer wall of the sub-air duct 425 is provided with a plurality of groups of air outlets 424 spaced apart from each other in the horizontal direction with the bottom of the fixed box 411. The lower end of the main air duct 421 is connected with the tube body 311. The hot air flow is transported to the cavity of the fixed box 411 through the main air duct 421, and then transported in layers through the group air ducts 425 and sprayed out through the air outlet 424 to dry each layer of the lily.

[0063] Specifically, the difference between the air equalizing component 42A and the air equalizing component 42B is that the branch air duct 425 is set at a different height. The air equalizing component 42A and the air equalizing component 42B are alternately installed in the inner cavity of the fixed box 411. As the main air duct 421 rotates, the lily pile heating layer can be horizontally divided into four layers. By reducing the number of sets of single-component air ducts 425, the pushing resistance of the branch air duct 425 to the lily layer is reduced when the main air duct 421 rotates, thereby reducing the wear between the driving gears and reducing damage to the lily itself.

[0064] See also Fig.16 The main air duct 421 includes a vertical air duct 4211, and a bell mouth 4212 is fixedly connected to the lower end of the vertical air duct 4211. During drying, the bell mouth 4212 is located in the tube body 311, which increases the air intake of the vertical air duct 4211 while preventing the lower end of the main air duct 421 from escaping from the tube body 311 during movement.

[0065] It can be understood that the diameter of the vertical air duct 4211 does not exceed the width of the first through groove and the second through groove, the width of the overlapping area of ​​the second lower sealing plate 312 and the second upper sealing plate 313, and the width of the overlapping area of ​​the first lower sealing plate 262 and the first lower sealing plate 262 are all greater than the diameter length of the vertical air duct 4211.

[0066] In summary, the present invention provides a multi-layer mesh belt type lily drying device. When the movable mesh plate 414 is located at the top, the movable mesh plate 414 is pulled out from the through slot 415, and two-thirds of the total volume of the fixed box 411 is put into the inlet 12, and the movable mesh plate 414 is pushed back into the fixed box 411. According to the above steps, the lily raw materials of each group are loaded in sequence. The driving motor 21 drives the conveyor belt 23 to transmit through the roller. The fixed box 411 is clamped on the driving rail 25 through the L-shaped mounting block 422. The driving assembly 24 installed on the side wall of the mounting plate 22 pushes the fixed box 411. The box body 411 reciprocates along the driving rail 25. When the fixed box body 411 reciprocates, the gear sleeve 423 engages with the tooth groove 252 so that the main air duct 421 drives the branch air duct 425 to rotate. The lower end of the main air duct 421 passes through the avoidance component 26 and is connected with the tube body 311. The heat flow is transported to the fixed box body 411 through the main air duct 421, and the heat flow is distributed to the lily layers of different heights through the branch air duct 425 for drying. The overlapping second lower sealing plate 312 and the second upper sealing plate 313 seal the second through groove without hindering the movement of the main air duct 421, thereby reducing heat waste.

[0067] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
