Description

Technical Field

[0001] The present invention relates to the technical field of hydrolysis and drying equipment, and specifically to a continuous hydrolysis and conversion equipment for processing animal body feathers. Background Technique

[0002] An animal body feather hydrolysis and drying equipment is a device specifically used for hydrolyzing and drying animal body feathers. Its purpose is to convert the protein in the feathers into usable feed or other products, and at the same time remove the moisture in the feathers for easy storage and transportation. Specifically, the animal body feathers are fed into a hydrolysis tank, where the feathers are mixed with water and heated to a certain temperature, and an appropriate amount of acid or enzyme catalyst is added. Under certain temperature and pH conditions, the hydrolysis process can effectively decompose the feathers. After a certain period of time, the hydrolyzed and dried body feather powder is discharged. The design and operation of the animal body feather hydrolysis and drying equipment consider environmental protection, energy conservation, high efficiency, and product quality, meeting the needs of modern industrial production.

[0003] Existing continuous hydrolysis and conversion equipment has certain drawbacks. When the body feathers are fed into the inner part of the hydrolysis and drying machine cylinder, the hydrolyzed and dried body feather powder needs to be discharged at the discharge chute. However, every time the body feather powder fills the compression cavity, it needs to be manually discharged. The body feather powder accumulates in the compression cavity, making it difficult for the body feather powder in the compression cavity to be discharged from the compression cavity. To discharge the body feather powder in the compression cavity, and the body feather powder entering the compression cavity will flow back into the inner part of the hydrolysis and drying machine cylinder, resulting in the body feather powder entering the inner part of the hydrolysis and drying machine cylinder again, affecting the hydrolysis and drying efficiency of the hydrolysis and drying machine cylinder. Summary of the Invention

[0004] The purpose of the present invention is to provide a continuous hydrolysis and conversion equipment for processing animal body feathers to solve the problems raised in the above background technique.

[0005] The purpose of the present invention can be achieved through the following technical solutions:

[0006] A continuous hydrolysis and drying device for processing animal body feathers, including a hydrolysis and drying machine cylinder. One end of the hydrolysis and drying machine cylinder is provided with a driving mechanism, and the other end is provided with a discharge chute. The inner axis of the hydrolysis and drying machine cylinder is provided with a second rotating shaft, and a spiral conveying blade is arranged inside the hydrolysis and drying machine cylinder outside the second rotating shaft. The output end of the driving mechanism rotates synchronously with the second rotating shaft of the spiral conveying blade. A pushing structure is arranged at one end inside the hydrolysis and drying machine cylinder near the discharge chute. The pushing structure includes a hollow shaft, which is sleeved on the cylindrical surface of the second rotating shaft and rotates relative to the second rotating shaft. A first moving plate and a spiral blade are welded on the top surface of the T-shaped block outside the hollow shaft. The first moving plate and the spiral blade are integrally manufactured. The area between the first moving plate and the end of the hydrolysis and drying machine cylinder is a compression chamber. Both the first moving plate and the spiral blade are slidably connected to the cylindrical surface of the hollow shaft. The first moving plate is used to isolate the body feather powder on both sides of the first moving plate. The spiral direction of the spiral conveying blade is opposite to that of the spiral blade, and the spiral blade intermittently contacts the spiral conveying blade. A discharge port is opened on the surface edge of the first moving plate, and two closing plates are rotatably connected to the surface of the first moving plate. Connecting pins are arranged on the edges of the two closing plates close to each other, and the two closing plates are rotatably connected relative to the connecting pins. The air pressure change in the compression chamber in the closed air causes the discharge port to open or close.

[0007] As a preferred technical solution of the present invention, a T-shaped block is opened on the cylindrical surface of the hollow shaft. A T-shaped groove and a first telescopic spring are arranged inside the T-shaped block. The two ends of the first telescopic spring are respectively connected to the end of the T-shaped block and the inner wall of the T-shaped groove. The T-shaped block is slidably connected to the inside of the T-shaped groove. The spiral blade, the first reserved hole and the T-shaped block move synchronously. The T-shaped block is used to limit the moving direction of the spiral blade and the first reserved hole.

[0008] As a preferred technical solution of the present invention, two sliding grooves are opened at the discharge port inside the first moving plate. Sliding pins are inserted into the two sliding grooves. The sliding pins are slidably connected to the inside of the sliding grooves. The two sliding pins are respectively connected to the corners of the two closing plates. The two closing plates are arranged in a straight line or in a V-shaped arrangement.

[0009] As a preferred technical solution of the present invention, T-shaped columns are inserted at the two inner walls of the first moving plate where they contact the two closing plates. A second telescopic spring is sleeved outside the T-shaped columns. The T-shaped columns are slidably connected to the inside of the first moving plate. The ends of the T-shaped columns contact the edges of the closing plates.

[0010] As a preferred technical solution of the present invention, when the spiral blade approaches the spiral conveying blade, the volume of the compression chamber of the hydrolysis and drying machine cylinder becomes larger, and the two closing plates open to balance the air pressure on both sides of the first moving plate.

[0011] As a preferred technical solution of the present invention, when the spiral blade is away from the spiral conveying blade, the volume of the compression chamber of the hydrolysis dryer cylinder becomes smaller, the two closing plates are always in a closed state, and the first moving plate is used to extrude and discharge the body feather meal.

[0012] As a preferred technical solution of the present invention, a control structure is provided at the end of the hydrolysis dryer cylinder and at the ends of the second rotating shaft and the hollow shaft. The control structure includes a fixed block welded to the end of the hydrolysis dryer cylinder. A first bevel gear is provided inside the fixed block at the end of the second rotating shaft, and a second bevel gear is provided inside the fixed block at the end of the hollow shaft. A threaded column is provided inside the upper surface of the fixed block, and the threaded column is threadedly connected to the fixed block. A first rotating shaft is provided inside the threaded column, and the first rotating shaft is rotatably connected to the inside of the threaded column. A third bevel gear is provided above the first bevel gear and the second bevel gear at the end of the first rotating shaft. The third bevel gear is located between the first bevel gear and the second bevel gear. A conical block is provided directly below the third bevel gear. A second moving plate is sleeved on the end of the second rotating shaft. A third telescopic spring is provided on one side of the second moving plate on the cylindrical surface of the second rotating shaft. Two fixing columns are welded to the surface of the second moving plate. Reserved grooves are provided on the cylindrical surfaces of the two fixing columns. Two matching holes are provided on the end face of the second bevel gear, and the positions of the matching holes are aligned with the positions of the fixing columns.

[0013] As a preferred technical solution of the present invention, a second reserved hole is provided in the middle of the second moving plate, and the inside of the second reserved hole is movably connected to the second rotating shaft. The two inclined surfaces of the reserved groove are in an inverted V shape, and the conical block is slidably connected to the reserved groove. The generatrix of the conical block is parallel to one of the generatrixes of the reserved groove. A swing plate is provided at the top of the threaded column.

[0014] As a preferred technical solution of the present invention, the threaded column and the third bevel gear move downward synchronously. The edges of the third bevel gear are respectively engaged with the first bevel gear and the second bevel gear. The conical block contacts the inside of the reserved groove. The end of the fixing column is away from the inside of the matching hole, and the third telescopic spring is compressed by the second moving plate. The rotating directions of the first bevel gear and the second bevel gear are opposite.

[0015] As a preferred technical solution of the present invention, the threaded column and the third bevel gear move upward synchronously. The third bevel gear is separated from the first bevel gear and the second bevel gear. The conical block is separated from the inside of the reserved groove. The length of the third telescopic spring becomes longer. The fixing column is matched with the inside of the matching hole. The first bevel gear and the second bevel gear rotate synchronously.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] A pushing structure is provided. The body feather powder is isolated by the first moving plate. Under the action of the first telescopic spring, the T-shaped block moves along the T-shaped groove. The spiral blade and the spiral conveying blade approach or move away from each other, changing the volume above the discharge chute and thus changing the air pressure above the discharge chute. This can not only suck the body feather powder inside the hydrolysis dryer cylinder into the discharge chute, but also discharge the body feather powder above the discharge chute from the discharge chute.

[0018] When the two closing plates of the pushing structure are opened or closed, the two closing plates can be opened or closed when the air pressure changes at the first moving plate, thus realizing the automatic entry and discharge of the body feather powder and preventing the body feather powder from flowing back into the interior of the hydrolysis dryer cylinder.

[0019] A control structure is provided. The third bevel gear can be engaged with the first bevel gear and the second bevel gear at the same time, so that the second rotating shaft and the hollow shaft rotate in opposite directions, controlling the spiral blade and the spiral conveying blade to approach or move away from each other, and also realizing the automatic entry and discharge of the body feather powder.

[0020] When the third bevel gear is separated from the first bevel gear and the second bevel gear, the second rotating shaft and the hollow shaft rotate synchronously, ensuring that the spiral blade and the spiral conveying blade rotate synchronously, ensuring that the positions of the first moving plate and the closing plate are always in the closed state, and isolating the body feather powder on both sides of the first moving plate.

Specific embodiments

[0032] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0033] Embodiment 1:

[0034] Please refer to Figures 1-6As shown in the figure, a continuous hydrolysis and drying device for animal body feathers includes a hydrolysis and drying machine cylinder 1. A driving mechanism 2 is provided at one end of the hydrolysis and drying machine cylinder 1, and a discharge chute 3 is provided at the other end of the hydrolysis and drying machine cylinder 1. A second rotating shaft 7 is arranged along the inner axis of the hydrolysis and drying machine cylinder 1, and a spiral conveying blade 6 is arranged outside the second rotating shaft 7 and inside the hydrolysis and drying machine cylinder 1. The output end of the driving mechanism 2 rotates synchronously with the second rotating shaft 7 of the spiral conveying blade 6. The driving mechanism 2 drives the second rotating shaft 7 to rotate, thereby driving the second rotating shaft 7 and the spiral conveying blade 6 to rotate. The spiral conveying blade 6 can process the feathers entering the interior of the hydrolysis and drying machine cylinder 1, decompose and dry the feathers inside the hydrolysis and drying machine cylinder 1 into powder, and convey the body feather powder to the other end of the hydrolysis and drying machine cylinder 1. A pushing structure 4 is provided at one end inside the hydrolysis and drying machine cylinder 1 near the discharge chute 3. The pushing structure 4 includes a hollow shaft 41. The hollow shaft 41 is sleeved on the cylindrical surface of the second rotating shaft 7, and the hollow shaft 41 rotates relative to the second rotating shaft 7. After the hollow shaft 41 and the second rotating shaft 7 rotate relative to each other, the edge of the spiral blade 43 can slide against the edge of the spiral conveying blade 6. A first moving plate 42 and a spiral blade 43 are welded to the top surface of the T-shaped block 45 outside the hollow shaft 41. The first moving plate 42 and the spiral blade 43 are integrally manufactured. The area between the first moving plate 42 and the end of the hydrolysis and drying machine cylinder 1 is a compression chamber 8. Both the first moving plate 42 and the spiral blade 43 are slidably connected to the cylindrical surface of the hollow shaft 41. While the hollow shaft 41 drives the spiral blade 43 to rotate, the spiral blade 43 will move along the axial direction. The first moving plate 42 is used to isolate the body feather powder on both sides of the first moving plate 42. The spiral direction of the spiral conveying blade 6 is opposite to that of the spiral blade 43. The spiral blade 43 intermittently contacts the spiral conveying blade 6, and the spiral blade 43 approaches or moves away from the spiral conveying blade 6, thereby changing the size of the space in the compression chamber 8. An outlet 413 is provided at the surface edge of the first moving plate 42, and two closing plates 46 are rotatably connected to the surface of the first moving plate 42. Connecting pins 410 are provided at the edges of the two closing plates 46 close to each other. The two closing plates 46 are rotatably connected relative to the connecting pins 410. The air pressure change in the compression chamber 8 in a closed air environment causes the outlet 413 to open or close. When the first moving plate 42 approaches the spiral conveying blade 6, the internal volume of the compression chamber 8 becomes larger, so the air pressure inside the compression chamber 8 becomes smaller. The air pressure inside the hydrolysis and drying machine cylinder 1 pushes the closing plate 46 to open, and the body feather powder enters the interior of the compression chamber 8 from the outlet 413. At this time, the air pressure inside the compression chamber 8 is balanced, and then the closing plate 46 closes.

[0035] Please refer to Figure 3 and Figure 5As shown, a T-shaped block 45 is provided on the cylindrical surface of the hollow shaft 41. Inside the T-shaped block 45, there are a T-shaped groove 48 and a first telescopic spring 49. The two ends of the first telescopic spring 49 are respectively connected to the end of the inner wall of the T-shaped block 45 and the T-shaped groove 48. The T-shaped block 45 is slidably connected to the inside of the T-shaped groove 48. The first telescopic spring 49 can push the T-shaped block 45, the first moving plate 42, and the spiral blade 43, causing the spiral blade 43 to move along the generatrix direction. The spiral blade 43, the first reserved hole 44, and the T-shaped block 45 move synchronously. The T-shaped block 45 is used to limit the moving direction of the spiral blade 43 and the first reserved hole 44. Since the spiral direction of the spiral blade 43 is opposite to that of the spiral conveying blade 6, the spiral blade 43 contacts different parts of the spiral conveying blade 6, and the position of the spiral blade 43 changes, which can change the space capacity of the compression chamber 8.

[0036] Please refer to Figure 5 As shown, two sliding grooves are provided inside the first moving plate 42 and at the discharge port 413. Inside both of the two sliding grooves, there is a sliding pin 47 inserted. The sliding pin 47 is slidably connected to the inside of the sliding groove. The shape of the sliding pin 47 is T-shaped, and the end of the sliding pin 47 slides inside the sliding groove. The two sliding pins 47 are respectively connected to the corners of the two closing plates 46. The two closing plates 46 are arranged in a straight line or in a V-shaped arrangement. When the sliding pins 47 of the two closing plates 46 approach each other, they are arranged in a V-shaped arrangement. When the sliding pins 47 of the two closing plates 46 move away from each other, they are arranged in a straight line.

[0037] Please refer to Figure 5 As shown, T-shaped columns 411 are inserted into the two inner walls of the first moving plate 42 and at the contact positions with the two closing plates 46. The T-shaped columns 411 are movably connected inside the first moving plate 42. A second telescopic spring 412 is sleeved outside the T-shaped columns 411. The T-shaped columns 411 can extend or shorten along the inside of the first moving plate 42. The T-shaped columns 411 are slidably connected to the inside of the first moving plate 42. The ends of the T-shaped columns 411 contact the edges of the closing plates 46. The two closing plates 46 approach or move away from each other, thereby discharging the body feather meal from the discharge port 413.

[0038] Please refer to Figure 5 As shown, when the spiral blade 43 approaches the spiral conveying blade 6, the volume of the compression chamber 8 of the hydrolysis dryer cylinder 1 becomes larger, so the air pressure inside the compression chamber 8 of the hydrolysis dryer cylinder 1 becomes smaller. At this time, the two closing plates 46 can be opened. After the two closing plates 46 are opened, the air pressure on both sides of the first moving plate 42 is balanced, and the body feather meal inside the hydrolysis dryer cylinder 1 can be discharged into the compression chamber 8.

[0039] Please refer to Figure 4As shown, when the spiral blade 43 is far away from the spiral conveying blade 6, the volume of the compression chamber 8 of the hydrolysis dryer cylinder 1 becomes smaller, and the air pressure inside the compression chamber 8 of the hydrolysis dryer cylinder 1 becomes larger, so that the two closing plates 46 in the shape of an eight become in a straight line. The two closing plates 46 are always in a closed state. The first moving plate 42 is used to extrude and discharge the body feather meal, and can push the body feather meal that entered the compression chamber 8 before to the discharge chute 3 for discharge.

[0040] It should be noted that the animal body feathers are placed inside the hydrolysis dryer cylinder 1, so that the spiral conveying blade 6 in the hydrolysis dryer cylinder 1 can decompose the feathers into body feather meal, and then dry and convey the body feather meal to the inside of the compression chamber 8. Specifically, under the action of the first telescopic spring 49, the T-shaped block 45 slides along the inside of the T-shaped groove 48. The T-shaped block 45 drives the first moving plate 42 and the spiral blade 43 to move axially. Since the spiral direction of the spiral blade 43 is opposite to that of the spiral conveying blade 6, the position where the spiral blade 43 contacts the spiral conveying blade 6 can be changed. The movement of the first moving plate 42 causes the space of the compression chamber 8 to become larger, and the air pressure inside the compression chamber 8 becomes smaller, so that the body feather meal in the hydrolysis dryer cylinder 1 opens the two closing plates 46, and then the body feather meal enters the inside of the compression chamber 8. After the air pressure inside the compression chamber 8 is balanced, the closing plates 46 are closed again. The body feather meal that enters the compression chamber 8 is retained inside the compression chamber 8. When the second rotating shaft 7 and the hollow shaft 41 rotate relative to each other, the spiral blade 43 will move away from the spiral conveying blade 6, and the space inside the compression chamber 8 is compressed, so that the pressure inside the compression chamber 8 becomes larger, and the opened closing plates 46 can also be closed. Since the first moving plate 42 is far away from the spiral conveying blade 6, the body feather meal inside the closed compression chamber 8 is discharged from the discharge chute 3.

[0041] Please refer to Figure 2 and Figures 6-9As shown in the figure, a control structure 5 is provided at the end of the hydrolysis dryer cylinder body 1 and at the ends of the second rotating shaft 7 and the hollow shaft 41. The control structure 5 includes a fixing block 51, and the fixing block 51 is welded to the end of the hydrolysis dryer cylinder body 1. The second rotating shaft 7 is rotatably connected to the fixing block 51. At the end of the second rotating shaft 7 and inside the fixing block 51, a first bevel gear 52 is provided. At the end of the hollow shaft 41 and inside the fixing block 51, a second bevel gear 53 is provided. Inside the upper surface of the fixing block 51, a threaded column 56 is provided. The threaded column 56 is threadedly connected to the fixing block 51, so that the threaded column 56 is lifted and lowered along the vertical direction. Inside the threaded column 56, a first rotating shaft 514 is provided. The first rotating shaft 514 is rotatably connected to the inside of the threaded column 56. The first rotating shaft 514 is lifted and lowered synchronously with the threaded column 56. At the end of the first rotating shaft 514 and above the first bevel gear 52 and the second bevel gear 53, a third bevel gear 54 is provided. The third bevel gear 54 is located between the first bevel gear 52 and the second bevel gear 53. The third bevel gear 54 meshes with the first bevel gear 52 and the second bevel gear 53 or the third bevel gear 54 is separated from the first bevel gear 52 and the second bevel gear 53. Directly below the third bevel gear 54, a tapered block 57 is provided. The third bevel gear 54 and the tapered block 57 are lifted and lowered synchronously. A second moving plate 59 is sleeved on the end of the second rotating shaft 7. The second moving plate 59 is movably connected to the cylindrical surface of the second rotating shaft 7. On the cylindrical surface of the second rotating shaft 7 and on one side of the second moving plate 59, a third telescopic spring 58 is provided. Two fixing columns 510 are welded to the surface of the second moving plate 59. The fixing columns 510 penetrate through the inside of the first bevel gear 52. Reserved grooves 511 are formed on the cylindrical surfaces of the two fixing columns 510. Two mating holes 512 are formed on the end face of the second bevel gear 53. The positions of the mating holes 512 are aligned with the positions of the fixing columns 510. The tapered block 57 can approach or move away from the reserved grooves 511, so as to control the separation or engagement of the fixing columns 510 and the mating holes 512.

[0042] Please refer to Figures 6-9 As shown in the figure, a second reserved hole 513 is formed in the exact middle of the second moving plate 59. The inside of the second reserved hole 513 is movably connected to the second rotating shaft 7, so that the second reserved hole 513 moves upward along the second rotating shaft 7. The two inclined surfaces of the reserved groove 511 are in an inverted V shape. The tapered block 57 is slidably connected to the reserved groove 511. The generatrix of the tapered block 57 is parallel to one of the generatrices of the reserved groove 511. The lifting of the tapered block 57 can ensure the sliding of the reserved groove 511 and the tapered block 57. A swing plate 55 is provided at the top end of the threaded column 56. By rotating the swing plate 55, the threaded column 56 is rotated, so that the third bevel gear 54 and the tapered block 57 are lifted and lowered.

[0043] Please refer to Figure 8As shown, the threaded post 56 and the third bevel gear 54 move downward synchronously. The edges of the third bevel gear 54 are respectively engaged with the first bevel gear 52 and the second bevel gear 53. Thus, the third bevel gear 54 can reverse the rotation directions of the first bevel gear 52 and the second bevel gear 53. At this time, the rotation directions of the spiral blade 43 and the spiral conveying blade 6 are opposite. The tapered block 57 is in contact with the inside of the reserved groove 511. The end of the fixed post 510 is far from the inside of the mating hole 512. The third telescopic spring 58 is compressed by the second moving plate 59. Thus, the end of the fixed post 510 is pulled out from the inside of the mating hole 512, so as not to affect the rotation of the first bevel gear 52 and the second bevel gear 53. The rotation directions of the first bevel gear 52 and the second bevel gear 53 are opposite.

[0044] Please refer to Figure 9 As shown, the threaded post 56 and the third bevel gear 54 move upward synchronously. The third bevel gear 54 is separated from the first bevel gear 52 and the second bevel gear 53. The first bevel gear 52 and the second bevel gear 53 do not rotate in opposite directions. The tapered block 57 is separated from the inside of the reserved groove 511. The length of the third telescopic spring 58 becomes longer. The third telescopic spring 58 can push the second moving plate 59 to cause the fixed post 510 to change its position. The fixed post 510 is engaged with the inside of the mating hole 512. The first bevel gear 52 and the second bevel gear 53 rotate synchronously. After the mating hole 512 is inserted by the fixed post 510, the first bevel gear 52 and the second bevel gear 53 move synchronously. At this time, the spiral blade 43 and the spiral conveying blade 6 do not rotate relative to each other.

[0045] When it is necessary to rotate the hollow shaft 41 and the second rotating shaft 7 in opposite directions, the swing plate 55 can be rotated to move the first rotating shaft 514 and the third bevel gear 54 inside the threaded post 56 downward. The edges of the third bevel gear 54 are engaged with the first bevel gear 52 and the second bevel gear 53. The rotation directions of the first bevel gear 52 and the third bevel gear 54 are opposite. The tapered block 57 below the third bevel gear 54 moves downward along with the third bevel gear 54. The third bevel gear 54 is engaged with the reserved groove 511 of the fixed post 510. Thus, the tapered block 57 pushes the fixed post 510 to move. The fixed post 510 is pulled out from the mating hole 512. The removed fixed post 510 does not affect the relative rotation of the first bevel gear 52 and the second bevel gear 53. The driving mechanism 2 drives the first bevel gear 52 of the second rotating shaft 7 to rotate. The spiral conveying blade 6 on the second rotating shaft 7 and the spiral blade 43 of the hollow shaft 41 are opposite. Thus, the spiral blade 43 rotates relative to the spiral conveying blade 6;

[0046] When the hollow shaft 41 needs to rotate in the same direction as the second rotating shaft 7, the rotating swing plate 55 drives the threaded column 56 to move upward. At this time, the third bevel gear 54 is separated from the first bevel gear 52 and the second bevel gear 53. The conical block 57 moves upward with the third bevel gear 54. The conical block 57 moves along the reserved groove 511, and the conical block 57 is away from the bottom end of the reserved groove 511. Thus, under the action of the third telescopic spring 58, the second moving plate 59 is moved along the second rotating shaft 7. The two fixed columns 510 on the second moving plate 59 approach the fitting hole 512, and the fixed columns 510 are inserted into the interior of the fitting hole 512. The fixed columns 510 can engage the first bevel gear 52 and the second bevel gear 53. The first bevel gear 52 and the second bevel gear 53 rotate synchronously. The spiral blade 43 and the screw conveyor blade 6 will not rotate relative to each other, and the first moving plate 42 will not move relative to the hollow shaft 41. Thus, it is ensured that the volume of the compression chamber 8 will not change, and the two closing plates 46 inside the discharge port 413 will not open. The first moving plate 42 can be used to partition the body feather meal inside the hydrolysis dryer cylinder 1.
