Description

Technical Field

[0001] This invention relates to the field of heat recovery and utilization technology, and specifically to a pellet feed drying device. Background Technology

[0002] The processing of pelleted feed includes drying technology. The core purpose is to ensure feed quality, extend storage time, and improve feeding safety, while also taking into account the stability of processing and transportation. Traditional drying equipment can only dry pelleted feed, but lacks waste heat recovery methods, which causes the generated waste heat to be directly discharged through the ventilation vents, resulting in energy waste.

[0003] To address the problems of traditional drying devices, Chinese Patent No. CN222881768U discloses a waste heat recovery device for feed processing. This device includes a feed processing oven with an air chamber installed on its left side and a hot air blower mounted on the air chamber. A waste heat recovery mechanism is located on the right side of the oven. The waste heat recovery mechanism includes a mounting frame and a heat recovery water tank, with a sealing plate fixedly connected between the mounting frame and the heat recovery water tank. This device can dry the feed and transfer heat to the water stored in the heat recovery water tank through the waste heat recovery mechanism, generating high-temperature hot water. The high-temperature hot water generated in the heat recovery water tank can be discharged through an outlet pipe for municipal heating or process heating, helping enterprises achieve energy conservation and emission reduction goals and improving resource utilization.

[0004] The above-mentioned device has the following problems during actual use: The high-temperature hot air generated by the hot air blower enters the feed processing oven to dry the feed and remove the moisture. However, if the feed is stacked in the feed processing oven, the drying effect of the feed that can be directly affected by the high-temperature hot air will inevitably be greater than that of other feed locations, resulting in uneven drying and affecting the overall drying effect. Summary of the Invention

[0005] The present invention aims to provide a pellet feed drying device to solve the problem of uneven drying in existing pellet feed drying methods.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a pellet feed drying device, comprising a cylinder and a water tank fixedly connected to the cylinder, a recovery pipe penetrating the interior of the water tank and communicating with the cylinder, and an output pipe communicating with the water tank; the cylinder is provided with an inlet and an outlet, and a sealing plate is detachably connected to the outlet; a rotating shaft is rotatably connected inside the cylinder, and a plurality of turning arms are provided on the rotating shaft along the axial direction of the rotating shaft; a lifting plate is provided inside the cylinder, and the lifting plate can move vertically inside the cylinder; a through hole is provided on the lifting plate, and the rotating shaft passes through the through hole; it also includes an introduction mechanism for introducing hot air into the cylinder, a drive mechanism for driving the rotating shaft to rotate, and a linkage mechanism for driving the lifting plate to move vertically reciprocally as the rotating shaft rotates.

[0007] The principles and advantages of this scheme are: 1. The pelleted feed is introduced into the cylinder through the feed inlet, so that the pelleted feed is located on the surface of the lifting plate. Hot air is introduced into the cylinder through the introduction mechanism to dry the pelleted feed. Compared with the existing technology, the drive mechanism drives the rotating shaft to rotate, and the rotating shaft drives multiple turning arms to turn the pelleted feed and change the position of the pelleted feed, thereby promoting uniform drying of the pelleted feed.

[0008] 2. During the rotation of the shaft, the lifting plate is driven to move vertically back and forth through the linkage mechanism. At the same time, the vertical distance between the lifting plate and multiple turning arms changes continuously, so that multiple turning arms can turn the pellet feed at different positions, change the position of the pellet feed, and thus promote the uniform drying of the pellet feed.

[0009] 3. The hot air inside the cylinder flows upward and enters the recovery pipe for discharge. The heat in the recovery pipe is transferred to the water stored in the water tank. Under the heat transfer, the temperature of the water stored in the water tank rises. The high-temperature hot water generated in the water tank can be discharged through the output pipe for municipal heating or process heating, thus realizing the reuse of heat.

[0010] Furthermore, the introduction mechanism includes an air cylinder and an annular block. An inlet pipe is connected to the air cylinder, which is fixedly connected to the cylinder. The air cylinder passes through the inner ring of the annular block and is connected to the inner ring of the annular block. Piston cylinders are provided on both sides of the bottom of the annular block. An air inlet pipe and an air outlet pipe are connected to the piston cylinder. The end of the air inlet pipe away from the piston cylinder is connected to the air cylinder, and the end of the air outlet pipe away from the piston cylinder is set towards the lifting plate. A piston block is slidably connected to the piston cylinder. It also includes an adjustment part that drives the two piston blocks to move vertically back and forth simultaneously with the vertical reciprocating motion of the lifting plate.

[0011] With the above configuration, during the vertical reciprocating motion of the lifting plate, the adjustment unit simultaneously drives the two piston blocks to reciprocate vertically, thereby allowing the hot air in the air cylinder to act on the pellet feed through the air inlet pipe, piston cylinder, and air outlet pipe, thus drying the pellet feed.

[0012] Furthermore, the air cylinder is provided with an annular groove 1, and a slider is slidably connected in the annular groove 1. The slider is fixedly connected to the inner wall of the annular block, and the annular block can rotate inside the cylinder. The adjustment part includes an annular groove 2 opened on the top of the lifting plate, an adjustment block fixedly connected to the piston block, and side blocks fixedly connected to both sides of the rotating shaft. The adjustment block and the side blocks are vertically slidably connected, and the end of the adjustment block away from the piston block is slidably connected to the annular groove 2.

[0013] With the above settings, during the rotation of the shaft, the shaft drives the adjusting block to move along the path of the second annular groove through the side block. The adjusting block can be used to turn the pellet feed and change its position. In addition, after the lifting plate moves the pellet feed upward, the side block can also turn the pellet feed and promote the change of the pellet feed's position.

[0014] During the rotation of the adjusting block, the adjusting block drives the slider to move along the path of the first annular groove through the side block, piston block, piston cylinder, and annular block; during the vertical reciprocating motion of the lifting plate, the lifting plate drives the piston block to move vertically reciprocating inside the piston cylinder through the second annular groove and the adjusting block.

[0015] Furthermore, the side block has an internal cavity, and the bottom of the side block has several jet pipes that communicate with the cavity. The jet pipes are positioned in the direction of the lifting plate. The end of the exhaust pipe away from the piston cylinder is fixed to the side block, and the end of the exhaust pipe away from the piston cylinder communicates with the cavity.

[0016] With the above configuration, during the vertical reciprocating motion of the lifting plate, the lifting plate drives the piston block to move vertically and reciprocating within the piston cylinder via the annular groove and adjusting block. This allows hot air from the air cylinder to be introduced into the jet pipe through the air inlet pipe, piston cylinder, air outlet pipe, and cavity. The hot air is then ejected from the jet pipe and acts on the pelleted feed, thus drying the pelleted feed. Furthermore, after the lifting plate moves the pelleted feed upwards, the side block can also turn the pelleted feed, allowing the jet pipe to penetrate into the pelleted feed at different depths, promoting uniform drying of the pelleted feed.

[0017] Furthermore, an arc-shaped elastic block is provided between the side block and the side wall of the adjusting block near the lifting plate, with the protrusion of the elastic block facing the inner wall of the cylinder.

[0018] With the above settings, during the rotation of the shaft, the shaft drives the elastic block to rotate synchronously through the side block and the adjusting block. The elastic block can change the position of the pellet feed, promoting uniform drying. Furthermore, during the vertical reciprocating motion of the lifting plate, the distance between the bottom of the side block and the adjusting block decreases intermittently, causing the degree of protrusion of the elastic block to change continuously. That is, the position of the protrusion of the elastic block changes, which can act on the pellet feed in different positions in the horizontal direction, expanding the turning range of the pellet feed and changing the position of the pellet feed to a greater extent.

[0019] Furthermore, the protrusions of the elastic block are provided with an elastic layer, and the inner wall of the cylinder is located on the movement trajectory of the elastic layer.

[0020] With the above settings, when the distance between the side block and the bottom of the adjusting block is at its minimum, the deformation of the elastic block is at its maximum, that is, the protrusion of the elastic block is at its maximum. At this time, the protrusion of the elastic block causes the elastic layer to abut against the inner wall of the cylinder. The rotating shaft drives the elastic block and the elastic layer to rotate synchronously through the side block and the adjusting block. The elastic layer can scrape the inner wall of the cylinder to prevent the pellet feed from adhering to the inner wall of the cylinder.

[0021] Furthermore, the protrusion of the elastic block is provided with several support blocks, and the side of the elastic layer near the elastic block is provided with several grooves. The end of the support block away from the elastic block abuts against the end of the groove away from the elastic block.

[0022] With the above configuration, since the end of the support block away from the elastic block abuts against the end of the groove away from the elastic block, the support block can support the elastic layer, thereby strengthening the contact strength between the elastic layer and the inner wall of the cylinder, and thus enhancing the scraping effect.

[0023] Furthermore, the linkage mechanism includes a cylindrical cam coaxially connected to the rotating shaft, a fixed plate fixedly connected to the cylinder, a curved groove on the cylindrical cam, and a linkage block slidably connected in the curved groove; the fixed plate is located below the lifting plate, the linkage block is vertically slidably connected to the fixed plate, and the end of the linkage block away from the curved groove is fixedly connected to the lifting plate.

[0024] With the above settings, during the rotation of the shaft, the shaft drives the cylindrical cam to rotate, and the cylindrical cam drives the linkage block to reciprocate vertically through the curved groove. The linkage block drives the lifting plate to reciprocate vertically.

[0025] Furthermore, a side box is provided on the side wall of the cylinder, and a movable plate is vertically slidably connected inside the side box. A bottom block is provided at the bottom of the movable plate, and the bottom block is vertically slidably connected to the bottom of the side box. A wall groove is provided on the side wall of the cylinder, and a wall block is slidably connected inside the wall groove. One end of the wall block is fixedly connected to the linkage block, and the other end of the wall block is fixedly connected to the bottom block. A discharge pipe and a return pipe are connected between the cylinder and the side box. The discharge pipe is located above the return pipe, and both the discharge pipe and the return pipe are located on the movement trajectory of the lifting plate.

[0026] With the above setup, during the vertical reciprocating motion of the lifting plate driven by the linkage block, the linkage block drives the movable plate to move vertically and reciprocating synchronously through the wall block and bottom block. The surface of the lifting plate is located below the left end of the return pipe, and the surface of the movable plate is located below the right end of the return pipe. At this time, the pelleted feed in the side box enters the interior of the cylinder through the return pipe. When the lifting plate and the movable plate move upward to their highest position, the surface of the lifting plate is located below the left end of the discharge pipe, and the bottom of the lifting plate is located below the left end of the return pipe. At the same time, the surface of the movable plate is located below the right end of the discharge pipe, and the bottom of the movable plate is located below the right end of the return pipe. At this time, the pelleted feed in the cylinder enters the interior of the box through the discharge pipe. This method can further change the position of the pelleted feed in the cylinder and promote uniform drying. Attached Figure Description

[0029] Example The basics are as follows: Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 As shown: A pellet feed drying device includes a cylinder 10 and a water tank 11 fixedly connected to the cylinder 10. A recovery pipe 12 is fixedly connected to the water tank 11, penetrating the interior of the water tank 11. The recovery pipe 12 is not connected to the interior of the water tank 11, but is connected to the cylinder 10. The connection point between the recovery pipe 12 and the cylinder 10 is near the top of the cylinder 10. An output pipe 13 is connected to the water tank 11.

[0030] The cylinder 10 has an inlet and an outlet, with the inlet located above the outlet. A sealing block 14 is threaded onto the inlet, and a sealing plate 15 is threaded onto the outlet. A rotating shaft 20 is rotatably connected inside the cylinder 10, and several tilting arms 21 are fixedly connected to the rotating shaft 20 along its axial direction.

The inlet and outlet are both located on the surface of the lifting plate 22 at its initial position. A through hole is opened in the middle of the lifting plate 22, through which the rotating shaft 20 passes. The cylinder also includes a drive mechanism for rotating the rotating shaft 20. The drive mechanism is a motor 23, which is fixedly connected inside the cylinder 10. The output shaft of the motor 23 is coaxially connected to the rotating shaft 20. It also includes a linkage mechanism that drives the lifting plate 22 to reciprocate vertically as the rotating shaft 20 rotates. The linkage mechanism includes a cylindrical cam 24 coaxially connected to the rotating shaft 20 and a fixed plate 25 fixedly connected to the cylinder 10. The cylindrical cam 24 has a curved groove, and a linkage block 26 is slidably connected in the curved groove. The fixed plate 25 is located below the lifting plate 22, and the linkage block 26 is vertically slidably connected to the fixed plate 25. The end of the linkage block 26 away from the curved groove is fixedly connected to the lifting plate 22.

[0031] It also includes an introduction mechanism for introducing hot air into the cylinder 10. The introduction mechanism includes an air cylinder 30 and an annular block 31. An introduction pipe 32 is connected to the air cylinder 30. The air cylinder 30 is fixed to the cylinder 10 and passes through the top of the cylinder 10. The air cylinder 30 is cylindrical and its diameter is smaller than the inner diameter of the annular block 31. The air cylinder 30 passes through the inner ring of the annular block 31 and is connected to the inner ring of the annular block 31. Specifically, an annular groove 33 is opened on the air cylinder 30, and a slider 34 is slidably connected in the annular groove 33. The slider 34 is fixed to the inner wall of the annular block 31, and the annular block 31 can rotate inside the cylinder 10.

[0032] Piston cylinders 40 are fixedly connected to the bottom of both sides of the annular block 31. An air inlet pipe and an air outlet pipe 41 are connected to the piston cylinder 40. The end of the air inlet pipe away from the piston cylinder 40 is connected to the air cylinder 30. The end of the air outlet pipe away from the piston cylinder 40 is set towards the lifting plate 22. A piston block 42 is slidably connected to the piston cylinder 40. It also includes an adjustment part that drives the two piston blocks 42 to move vertically back and forth at the same time as the lifting plate 22 moves vertically back and forth. The adjustment part includes an annular groove 43 opened on the top of the lifting plate 22, an adjustment block 44 fixedly connected to the piston block 42, and side blocks 45 fixedly connected to both sides of the rotating shaft 20. The adjustment block 44 and the side blocks 45 are vertically slidably connected. The end of the adjustment block 44 away from the piston block 42 is slidably connected to the annular groove 43.

[0033] The side block 45 has an internal cavity. Several jet pipes 451 are fixed to the bottom of the side block 45, communicating with the cavity. The jet pipes 451 are oriented towards the lifting plate 22. The end of the exhaust pipe 41 away from the piston cylinder 40 is fixed to the side block 45, and the end of the exhaust pipe 41 away from the piston cylinder 40 communicates with the cavity. A first one-way valve is installed on the intake pipe for gas to enter the piston cylinder 40 unidirectionally from the air cylinder 30, and a second one-way valve is installed on the exhaust pipe 41 for gas to enter the cavity unidirectionally from the piston cylinder 40.

[0034] An arc-shaped elastic block 50 is fixed between the bottom sidewall of the side block 45 and the adjusting block 44. The elastic block 50 is an elastic iron sheet, and the protrusion of the elastic block 50 faces the inner wall of the cylinder 10. An elastic layer 51, which is a rubber layer, is fixed to the protrusion of the elastic block 50. The inner wall of the cylinder 10 is located on the movement trajectory of the elastic layer 51. That is, when the lifting plate 22 rises to the highest position, the distance between the bottom of the side block 45 and the adjusting block 44 is at its minimum, and the deformation of the elastic block 50 is at its maximum, that is, the protrusion of the elastic block 50 is at its maximum. At this time, the protrusion of the elastic block 50 causes the elastic layer 51 to abut against the inner wall of the cylinder 10. Several support blocks 52 are fixed to the protrusion of the elastic block 50. Several grooves 53 are opened on the side of the elastic layer 51 near the elastic block 50. The end of the support block 52 away from the elastic block 50 abuts against the end of the groove 53 away from the elastic block 50.

[0035] A side box 60 is fixedly connected to the side wall of the cylinder 10. A movable plate is vertically slidably connected inside the side box 60. A bottom block 61 is fixedly connected to the bottom of the movable plate. The bottom block 61 is vertically slidably connected to the bottom of the side box 60. A wall groove is vertically opened on the side wall of the cylinder 10. A wall block 62 is slidably connected inside the wall groove. One end of the wall block 62 is fixedly connected to the linkage block 26, and the other end of the wall block 62 is fixedly connected to the bottom block 61. A discharge pipe 63 and a return pipe 64 are connected between the cylinder 10 and the side box 60. The discharge pipe 63 is located above the return pipe 64. Both the discharge pipe 63 and the return pipe 64 are located on the movement trajectory of the lifting plate 22. The discharge pipe 63 is inclined from left to right. The height of the left end of the discharge pipe 63 is greater than the height of the right end of the discharge pipe 63. The return pipe 64 is inclined from left to right. The height of the left end of the return pipe 64 is less than the height of the right end of the return pipe 64.

[0036] The initial position of the surface of the lifting plate 22 is below the left end of the return pipe 64, and the initial position of the surface of the movable plate is below the right end of the return pipe 64. When the lifting plate 22 and the movable plate move upward to their highest positions, the surface of the lifting plate 22 is below the left end of the discharge pipe 63, and the bottom of the lifting plate 22 is below the left end of the return pipe 64. At the same time, the surface of the movable plate is below the right end of the discharge pipe 63, and the bottom of the movable plate is below the right end of the return pipe 64. That is, during the period when the lifting plate 22 rises to its highest position, the lifting plate 22 will block the recovery pipe 12; during the period when the movable plate rises to its highest position, the movable plate will also block the recovery pipe 12.

[0037] The specific implementation process is as follows: In use, hot air is introduced into the air cylinder 30 through the inlet pipe 32 for temporary storage; the pellet feed is introduced into the inside of the cylinder 10 through the feed inlet, so that the pellet feed is located on the surface of the lifting plate 22, and then the sealing block 14 is connected to the feed inlet to seal the feed inlet.

[0038] When the motor 23 is started, the output shaft of the motor 23 drives the rotating shaft 20 to rotate. The rotating shaft 20 drives multiple turning arms 21 to turn the pellet feed and change its position. During the rotation of the rotating shaft 20, the rotating shaft 20 drives the adjusting block 44 to move along the path of the second annular groove 43 through the side block 45. The adjusting block 44 can be used to turn the pellet feed and change its position. During the rotation of the adjusting block 44, the adjusting block 44 drives the slider 34 to move along the path of the first annular groove 33 through the side block 45, piston block 42, piston cylinder 40, and annular block 31.

[0039] During the rotation of the rotating shaft 20, the rotating shaft 20 drives the cylindrical cam 24 to rotate. The cylindrical cam 24 drives the linkage block 26 to move vertically and reciprocally through the curved groove. The linkage block 26 drives the lifting plate 22 to move vertically and reciprocally. The lifting plate 22 drives the pellet feed to move vertically and reciprocally. At the same time, the vertical distance between the lifting plate 22 and the multiple turning arms 21 continuously changes, so that the multiple turning arms 21 can turn the pellet feed at different positions and change the position of the pellet feed. In addition, after the lifting plate 22 drives the pellet feed to move upward, the side block 45 can also turn the pellet feed and promote the change of position of the pellet feed.

[0040] During the vertical reciprocating motion of the lifting plate 22, the lifting plate 22 drives the piston block 42 to reciprocate vertically within the piston cylinder 40 via the annular groove 43 and the adjusting block 44. This allows hot air from the air cylinder 30 to be introduced into the jet pipe 451 through the air inlet pipe, piston cylinder 40, air outlet pipe 41, and cavity. The hot air is then ejected from the jet pipe 451 and acts on the pelleted feed, thereby drying the pelleted feed. Furthermore, after the lifting plate 22 moves the pelleted feed upward, the side block 45 can also turn the pelleted feed, allowing the jet pipe 451 to penetrate the pelleted feed to different depths, promoting uniform drying of the pelleted feed. In addition, since the pelleted feed can be moved in various ways, it can also promote uniform drying of the pelleted feed.

[0041] Hot air flows upward and enters the recovery pipe 12 for discharge. The heat in the recovery pipe 12 is transferred to the water stored in the water tank 11. Under the heat transfer, the temperature of the water stored in the water tank 11 rises. The high-temperature hot water generated in the water tank 11 can be discharged through the output pipe 13 for municipal heating or process heating, thus realizing the reuse of heat.

[0042] During the rotation of the rotating shaft 20, the rotating shaft 20 drives the elastic block 50 to rotate synchronously through the side block 45 and the adjusting block 44. The elastic block 50 can change the position of the pellet feed, promoting uniform drying. Furthermore, during the vertical reciprocating motion of the lifting plate 22, the distance between the bottom of the side block 45 and the adjusting block 44 decreases intermittently, causing the degree of protrusion of the elastic block 50 to change continuously. That is, the position of the protrusion of the elastic block 50 changes, thereby acting on the pellet feed at different positions in the horizontal direction, expanding the turning range of the pellet feed, and changing the position of the pellet feed to a greater extent.

[0043] When the distance between the bottom of the side block 45 and the adjusting block 44 is at its minimum, the deformation of the elastic block 50 is at its maximum, that is, the protrusion of the elastic block 50 is at its maximum. At this time, the protrusion of the elastic block 50 causes the elastic layer 51 to abut against the inner wall of the cylinder 10. The rotating shaft 20 drives the elastic block 50 and the elastic layer 51 to rotate synchronously through the side block 45 and the adjusting block 44. The elastic layer 51 can scrape the inner wall of the cylinder 10, preventing the pellet feed from adhering to the inner wall of the cylinder 10. Furthermore, since the end of the support block 52 away from the elastic block 50 abuts against the end of the groove 53 away from the elastic block 50, the support block 52 can support the elastic layer 51, thereby strengthening the contact strength between the elastic layer 51 and the inner wall of the cylinder 10, and thus enhancing the scraping effect.

[0044] During the vertical reciprocating motion of the lifting plate 22 driven by the linkage block 26, the linkage block 26 drives the movable plate to move vertically and reciprocating synchronously through the wall block 62 and the bottom block 61. The initial position of the surface of the lifting plate 22 is below the left end of the return pipe 64, and the initial position of the surface of the movable plate is below the right end of the return pipe 64. At this time, the pellet feed in the side box 60 enters the interior of the cylinder 10 through the return pipe 64. When the lifting plate 22 and the movable plate move upward to their highest position, the surface of the lifting plate 22 is below the left end of the discharge pipe 63, and the bottom of the lifting plate 22 is below the left end of the return pipe 64. At the same time, the surface of the movable plate is below the right end of the discharge pipe 63, and the bottom of the movable plate is below the right end of the return pipe 64. At this time, the pellet feed in the cylinder 10 enters the interior of the box through the discharge pipe 63. This method can further change the position of the pellet feed in the cylinder 10 and promote uniform drying.
