Abstract
Description
Technical Field
[0001] This application relates to the technical field of feed drying, and more particularly to a feed production drying device. Background Technology
[0002] Drying is a crucial post-processing step in feed processing. Its purpose is to quickly reduce feed products with high moisture content after previous processes (such as conditioning and pelleting) to below safe storage moisture levels, so as to facilitate storage and transportation, prevent mold growth, and ensure feed quality.
[0003] Currently, rotary drum dryers are a widely used drying equipment in industrial feed production. Their basic working principle is as follows: wet feed to be dried is fed into the drum, which rotates slowly under the drive of a transmission device, causing the feed inside to tumble and move forward. During this process, hot air (provided by a heat source such as a hot air furnace) comes into contact with the feed in a parallel or counter-current manner, transferring heat to the feed through convection and conduction, causing the moisture in the feed to evaporate. Finally, the dried feed is discharged from the other end of the drum.
[0004] However, some feeds (especially those containing starch, sugar, or highly viscous ingredients) are prone to softening and melting of their surface components when heated, causing multiple particles to stick together and form large clumps or blocks. The mechanical dispersing force generated by the slow rotation of the drum is limited, making it difficult to effectively break up these solid clumps. The drying speed inside and outside the clumps is inconsistent, resulting in poor overall drying uniformity and low drying efficiency of the feed. Summary of the Invention
[0005] This application aims to at least partially address one of the technical problems in the related art.
[0006] Therefore, one objective of this application is to provide a feed production drying device in which, during the feed drying process, the feed is effectively dispersed by turning, hitting and shearing to ensure that it is in full contact with hot air, thereby improving the uniformity and efficiency of feed drying.
[0007] To achieve the above objectives, a first aspect of this application provides a feed production drying device, comprising a drying cylinder, a central shaft, multiple shovels, multiple crushing mechanisms, and multiple striking mechanisms. The drying cylinder is rotatably disposed between a first cover plate and a second cover plate. The first cover plate and the second cover plate are respectively provided with a hot air duct and an exhaust duct, which are respectively connected to the drying cylinder. The central shaft is rotatably disposed at the center of the drying cylinder, with one end of the central shaft connected to the second cover plate via a universal bracket, and the other end of the central shaft penetrating the first cover plate. Multiple shovels are evenly distributed on the central shaft. A toothed ring is provided at the center of the inner wall of the first cover plate, and the crushing mechanisms are meshed with the toothed ring. Each crushing mechanism is respectively connected to a corresponding shovel. Multiple striking mechanisms are respectively disposed on corresponding shovels. Each shovel has a transmission assembly on both sides, which is respectively connected to the crushing mechanism and the striking mechanism.
[0008] In addition, the feed production drying equipment proposed in this application may also have the following additional technical features:
[0009] In one embodiment of this application, the crushing mechanism includes a rotating shaft, multiple sets of crushing blades, and two first gears. The shovel plate is provided with multiple through slots near the central shaft, and the rotating shaft passes through the through slots and extends to both sides of the shovel plate. The multiple sets of crushing blades are all disposed on the rotating shaft and are respectively disposed in the corresponding through slots. The two first gears are respectively disposed at the ends of the rotating shaft, and one of the first gears is meshed with the gear ring.
[0010] In one embodiment of this application, the striking mechanism includes a guide plate, a striking plate, two springs, and a plurality of striking ribs. The two springs are symmetrically arranged on the shovel plate and connected to the striking plate. The guide plate is inclinedly arranged on one side of the shovel plate, and a guide channel is formed between the guide plate and the shovel plate. The striking plate is arranged at one end of the guide plate near the central axis. The plurality of striking ribs are evenly distributed on the opposite surfaces of the striking plate and the shovel plate.
[0011] In one embodiment of this application, the transmission assembly includes a connecting rod, a push-pull plate, a toothed plate, a transmission shaft, a second gear, and an eccentric wheel. The side wall of the shovel plate has a groove, within which a roller is slidably connected. The push-pull plate is connected to the roller. One end of the connecting rod is eccentrically hinged to the first gear, and the other end of the connecting rod is hinged to the push-pull plate. The toothed plate is disposed on the push-pull plate. A fixed plate is disposed on the shovel plate, and the transmission shaft is rotatably connected to the fixed plate. The second gear is disposed on the transmission shaft and meshes with the toothed plate. The eccentric wheel is eccentrically disposed at the end of the transmission shaft.
[0012] In one embodiment of this application, the push-pull plate is provided with a connecting plate, and a metal wire is provided between two oppositely arranged connecting plates. The metal wire is located below the slapping plate and is in contact with the surface of the shovel plate.
[0013] In one embodiment of this application, a driving member is hinged to the drying cylinder, and a sealing cover is hinged to the output end of the driving member. The sealing cover is connected to the drying cylinder through a hinge shaft.
[0014] Compared with the prior art, the present invention has at least the following beneficial effects: (1) During the rotation of the shovel plate driven by the central shaft, the rotating shovel plate scoops up the feed and forms an interlaced stirring with the rotating drum, which helps to improve the drying efficiency of the feed; (2) The striking mechanism and crushing mechanism on the shovel plate can continuously strike and shear the feed, effectively break up the clumps, and make it fully contact with the hot air, thereby improving the uniformity and efficiency of feed drying; (3) The reciprocating metal wire can effectively prevent the feed from sticking to the shovel plate and ensure that the shovel plate works continuously; (4) The transmission component can be used to simultaneously realize the start of the striking mechanism and the crushing mechanism as well as the reciprocating movement of the metal wire, which is compact and does not require additional drive.

[0024] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.
[0025] The feed production drying equipment of this application embodiment will be described below with reference to the accompanying drawings.
[0026] like Figures 1 to 6 As shown, the feed production drying equipment of this application embodiment may include a drying cylinder 1, a central shaft 2, multiple shovels 3, multiple crushing mechanisms 4, and multiple impact mechanisms 5.
[0027] The drying cylinder 1 is rotatably positioned between the first cover plate 10 and the second cover plate 13.
[0028] It should be noted that the first cover plate 10 and the second cover plate 13 can be installed on the ground through the upright plate, and the inner walls of the first cover plate 10 and the second cover plate 13 are provided with bearings, and the drying cylinder 1 is fixed to the inner ring of the bearing.
[0029] Furthermore, the drying cylinder 1 can be driven to rotate by a drive mechanism, see [link to relevant documentation]. Figure 2 The drive mechanism may be a gear set mechanism. The drive method and connection relationship of the drive mechanism are existing technologies in this field and will not be described in detail in this application.
[0030] In the embodiments of this application, the drying cylinder 1 has a heat-insulating cylinder structure, which can effectively reduce heat loss.
[0031] The first cover plate 10 and the second cover plate 13 are respectively provided with a hot air pipe 14 and an exhaust pipe 15, which are respectively connected to the drying cylinder 1.
[0032] It should be noted that the hot air duct 14 is connected to a hot air blower and is used to blow hot air into the drying cylinder 1; at the same time, the exhaust duct 15 is used to discharge the humid air after heat exchange, thereby reducing the humidity inside the drying cylinder 1.
[0033] Furthermore, to precisely control the drying temperature, a temperature sensor (not shown in the figure) connected to the temperature control system is installed inside the drying drum 1 to detect the temperature inside the drying drum 1 in real time. This not only optimizes the drying efficiency but also prevents the feed from being burned due to overheating, ensuring that its nutritional components are not destroyed.
[0034] The central shaft 2 is rotatably set at the center of the drying cylinder 1, and one end of the central shaft 2 is connected to the second cover plate 13 by a universal bracket 12. The other end of the central shaft 2 is set through the first cover plate 10, and multiple shovels 3 are evenly distributed on the central shaft 2.
[0035] It should be noted that the central shaft 2 is rotatably connected to the first cover plate 10 via a bearing, and one end of the central shaft 2 is connected to an external motor, see [reference]. Figure 1 The motor can be installed on the outside of the first cover plate 10. The motor can drive the central shaft 2 to rotate, thereby driving the shovel plate 3 to rotate.
[0036] Furthermore, in order to improve the feed drying effect, the rotation direction of the central shaft 2 and the drying cylinder 1 can be controlled to be opposite. The rotation of the drying cylinder 1 can cause the feed at the bottom to turn over, while the rotation of the central shaft 2 and the shovel plate 3 can shovel up the feed at the top, so as to disperse large pieces of feed. This staggered operation can effectively stir the feed and further improve the drying efficiency.
[0037] A toothed ring 11 is provided at the center of the inner wall of the first cover plate 10. The crushing mechanism 4 is meshed with the toothed ring 11, and multiple crushing mechanisms 4 are respectively connected to the corresponding shovel plates 3. Multiple striking mechanisms 5 are respectively provided on the corresponding shovel plates 3. A transmission assembly 6 is provided on both sides of each shovel plate 3, and the transmission assembly 6 is respectively connected to the crushing mechanism 4 and the striking mechanism 5.
[0038] It should be noted that the crushing mechanism 4 is located close to the central shaft 2. When the shovel 3 rotates with the central shaft 2, it can scoop up the feed inside the drying cylinder 1. The scooped feed slides with the shovel 3. The feed first passes through the striking mechanism 5, which strikes it. Then it passes through the crushing mechanism 4 to shear and crush it, so as to disperse large feed clumps. The feed can fully contact the hot air, which improves the drying effect and efficiency.
[0039] Furthermore, when the central shaft 2 rotates, it can drive the shovel plate 3 to rotate, and drive the crushing mechanism 4 set on the shovel plate 3 to rotate around the central shaft 2. Under the meshing constraint of the toothed ring 11, the crushing mechanism 4 can also rotate to shear and crush the lumpy feed. At the same time, with the cooperation of the transmission component 6, it can also drive the striking mechanism 5 to strike the feed on the shovel plate 3, further achieving the purpose of dispersing the feed.
[0040] To further clarify the above embodiments, in one embodiment of this application, such as Figure 4 As shown, the crushing mechanism 4 includes a rotating shaft 41, multiple sets of crushing blades 42, and two first gears 43. The shovel plate 3 is provided with multiple through slots 31 near the central shaft 2. The rotating shaft 41 passes through the through slots 31 and extends to both sides of the shovel plate 3. The multiple sets of crushing blades 42 are all arranged on the rotating shaft 41 and are respectively arranged in the corresponding through slots 31. The two first gears 43 are respectively arranged at the ends of the rotating shaft 41, and one of the first gears 43 is meshed with the gear ring 11.
[0041] It should be noted that the rotating shaft 41 is rotatably mounted on the shovel plate 3, and multiple through slots 31 are evenly arranged. Each through slot 31 contains multiple evenly arranged crushing blades 42. When the central shaft 2 rotates, it drives the shovel plate 3, the rotating shaft 41 and the first gear 43 to rotate around the central shaft 2. At this time, under the constraint of the gear ring 11, the first gear 43 meshing with the gear ring 11 can also rotate on its own and drive the crushing blades 42 to rotate, thereby crushing the lumpy feed. Then the feed passes through the through slot 31 and falls to the bottom of the drying cylinder 1.
[0042] Furthermore, such as Figure 6 As shown, the striking mechanism 5 includes a guide plate 51, a striking plate 52, two springs 53, and multiple striking ribs 54. The two springs 53 are symmetrically arranged on the shovel plate 3 and connected to the striking plate 52. The guide plate 51 is inclinedly arranged on one side of the shovel plate 3, and a guide channel is formed between the guide plate 51 and the shovel plate 3. The striking plate 52 is arranged at one end of the guide plate 51 near the central axis 2. The multiple striking ribs 54 are evenly distributed on the opposite surfaces of the striking plate 52 and the shovel plate 3.
[0043] It should be noted that the end of the guide plate 51 closer to the central axis 2 is closer to the shovel plate 3, while the end of the guide plate 51 further away from the central axis 2 is farther from the shovel plate 3, thus forming a guide channel with a large inlet and a small outlet, making it easier for feed to enter the guide channel.
[0044] Furthermore, the slapping plate 52 can continuously strike the feed on the shovel plate 3. The end of the slapping rib 54 is a triangular prism structure, which makes it easy to break the lumpy feed into small pieces. After being struck, the feed will slide down the inclined shovel plate 3 to the position of the crushing mechanism 4. Then, the crushing mechanism 4 will further shear and crush the feed to make the feed more evenly dispersed, which will help improve the drying effect and efficiency.
[0045] In one embodiment of this application, such as Figure 5 As shown, the transmission assembly 6 includes a connecting rod 61, a push-pull plate 62, a toothed plate 63, a transmission shaft 64, a second gear 65, and an eccentric wheel 66. The side wall of the shovel plate 3 has a groove 32, within which a roller is slidably connected. The push-pull plate 62 is connected to the roller. One end of the connecting rod 61 is eccentrically hinged to the first gear 43, and the other end is hinged to the push-pull plate 62. The toothed plate 63 is mounted on the push-pull plate 62. A fixed plate is mounted on the shovel plate 3, and the transmission shaft 64 is rotatably connected to the fixed plate. The second gear 65 is mounted on the transmission shaft 64 and meshes with the toothed plate 63. The eccentric wheel 66 is eccentrically positioned at the end of the transmission shaft 64.
[0046] In the embodiments of this application, the chute 32 is provided along the width direction of the shovel plate 3 (the extension line of the chute 32 points to the central axis 2), the chute 32 can restrict the movement direction of the push-pull plate 62, and the eccentric wheel 66 is located between the shovel plate 3 and the slapping plate 52.
[0047] Specifically, when the first gear 43 rotates, it can drive the connecting rod 61 to rotate. Under the restriction of the slide groove 32, the push-pull plate 62 moves back and forth along the length of the slide groove 32. Then, through the cooperation of the toothed plate 63, it drives the transmission shaft 64, the second gear 65 and the eccentric wheel 66 to rotate. During the rotation of the eccentric wheel 66, with the cooperation of the spring 53, it drives the patting plate 52 to vibrate continuously, thereby continuously hitting the feed on the shovel plate 3 to disperse large pieces of feed into small pieces.
[0048] In one embodiment of this application, such as Figure 6 As shown, the push-pull plate 62 is provided with a connecting plate 7, and a metal wire 8 is provided between the two oppositely arranged connecting plates 7. The metal wire 8 is located below the slapping plate 52, and the metal wire 8 is in contact with the surface of the shovel plate 3.
[0049] It should be noted that each shovel plate 3 has a connecting plate 7 on both sides, and a metal wire 8 is provided between the two connecting plates 7. When the push-pull plate 62 moves back and forth, the metal wire 8 moves back and forth with the cooperation of the connecting plates 7. Because the slapping ribs 54 continuously hit the feed, some feed may adhere to the shovel plate 3. The reciprocating metal wire 8 can effectively scrape off the feed on the shovel plate 3 to prevent feed residue.
[0050] In one embodiment of this application, such as Figure 2 As shown, a drive unit 16 is hinged to the drying cylinder 1, and a sealing cover 9 is hinged to the output end of the drive unit 16. The sealing cover 9 is connected to the drying cylinder 1 through a hinge shaft.
[0051] In the embodiments of this application, the drying cylinder 1 is provided with a feed inlet, which facilitates the feeding of feed into the drying cylinder 1 and the discharge of dried feed. The sealing cover 9 is placed on the feed inlet to seal it. The drying cylinder 1 is provided with a hinge shaft, and the sealing cover 9 is rotatably connected to the hinge shaft.
[0052] Specifically, the relevant personnel first put feed, which occupies about one-third of the volume of the drying cylinder 1, into the drying cylinder 1 through the feed inlet. Then, they start the drive component 16, which drives the sealing cover 9 to rotate around the hinge shaft until the feed inlet is completely covered, thus achieving a seal.
[0053] After sealing is completed, relevant personnel can control the rotation of the drying cylinder 1 and the central shaft 2, with the rotation directions of the central shaft 2 and the drying cylinder 1 being opposite. Hot air is introduced into the interior of the drying cylinder 1 through the hot air pipe 14. During the rotation of the drying cylinder 1, the feed inside can be continuously tumbled, which speeds up the feed drying efficiency.
[0054] As the central shaft 2 drives the shovel plate 3 to rotate, the striking mechanism 5 and the crushing mechanism 4 on the shovel plate 3 rotate (revolve) around the central shaft 2. Under the meshing constraint of the gear ring 11, the first gear 43 can also rotate, thereby driving the crushing mechanism 4 to rotate. At the same time, with the cooperation of the connecting rod 61, the push-pull plate 62 and the toothed plate 63 reciprocate, driving the transmission shaft 64, the second gear 65 and the eccentric wheel 66 to rotate. The outer edge of the eccentric wheel 66 contacts the striking plate 52. The outer edge of the eccentric wheel 66 periodically lifts (the striking plate 52 moves away from the shovel plate 3) and releases (the striking plate 52 moves closer to the shovel plate 3) the striking plate 52. When the striking plate 52 is lifted, the spring 53 is stretched. When the striking plate 52 is released, under the action of the elastic potential energy of the spring 53, the striking plate 52 quickly returns to its original position, thus forming a continuous striking action to efficiently disperse the feed.
[0055] At the same time, the central shaft 2 can also scoop up the feed in the opposite direction as the shovel plate 3 rotates from a low position to a high position (see...). Figure 4 The feed on the shovel plate 3 naturally slides towards the central axis 2. When the feed passes under the beater plate 52, it is subjected to continuous impact, and large pieces of feed are broken into smaller pieces. When the feed slides to the position of the through trough 31, the rotating crusher blade 42 further crushes the feed. These two crushing methods significantly improve the contact efficiency between the feed and the hot air, effectively enhancing the uniformity and efficiency of drying.
[0056] Furthermore, after continuous striking by the patting plate 52, some feed may stick to the shovel plate 3. The reciprocating motion of the push-pull plate 62 simultaneously drives the metal wire 8 to continuously rub against the surface of the shovel plate 3, which can effectively prevent feed from sticking to the shovel plate 3 and further improve the feed drying effect.
[0057] Moisture generated during the drying process will be discharged through the exhaust pipe 15. After drying is complete, the feed inlet of the drying cylinder 1 will rotate to the lower position. At this time, the drive unit 16 will be activated again to open the sealing cover 9, thus completing the unloading operation of the dried feed.
[0058] In summary, the feed production drying equipment of this application can effectively disperse clumps of feed by turning, hitting, and shearing the feed during the drying process, ensuring that the feed is in full contact with hot air, thereby improving the uniformity and efficiency of feed drying.
