Description

Technical Field

[0001] This utility model relates to the field of low-temperature drying technology, specifically to a low-temperature processing device for distiller's grains feed. Background Technology

[0002] Distillers' grains, a major byproduct of the brewing industry, are rich in nutrients and have a high moisture content. When used as animal feed, they require low-temperature drying to reduce moisture content. Existing drying equipment typically uses drum turning, but although the material is turned, the overall contact area with hot air remains relatively small, resulting in a prolonged drying time. Utility Model Content

[0003] To address the aforementioned technical deficiencies, the purpose of this utility model is to provide a low-temperature processing device for distiller's grains feed, which can spread the distiller's grains feed in multiple layers to increase the contact area with hot air and improve drying efficiency.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a low-temperature treatment device for distiller's grains feed, comprising:

[0005] A base, on which a frame is hinged;

[0006] A drying cylinder is rotatably mounted on a frame. One end of the drying cylinder is provided with a feed inlet and an air inlet, and the other end is provided with a discharge outlet and an air outlet. A dryer is fixed outside the drying cylinder.

[0007] Multiple first partitions and multiple second partitions are staggered inside the drying cylinder, with the first partitions and second partitions being parallel and both having notches.

[0008] The base is equipped with a drive mechanism for driving the frame to flip, and the drying cylinder is equipped with an adjustment mechanism for driving the second partition to rotate.

[0009] Preferably, the adjusting mechanism includes an inner shaft and an outer shaft, the outer shaft is sleeved on the inner shaft, the inner shaft is rotatably installed in the drying cylinder, the first partition is fixed on the outer shaft, and the second partition is fixed on the inner shaft.

[0010] Preferably, the upper and lower ends of the drying cylinder are rotatably mounted with limit seats, the two ends of the inner shaft are connected to the two limit seats by splines, the two ends of the inner shaft are fitted with limit rings, and springs are fitted on the inner shaft between the limit rings and the limit seats.

[0011] Preferably, a nylon ring is fitted on the inner shaft between the outer shaft and the two limiting rings, and the two ends of the outer shaft abut against the nylon ring.

[0012] Preferably, a key bar is fixed inside the drying cylinder, and a keyway is provided on the outer shaft to slide with the key bar.

[0013] Preferably, the outer shaft has multiple clearance grooves, and the inner shaft has multiple connecting blocks fixed thereon. The connecting blocks extend from the clearance grooves and are fixedly connected to the second partition.

[0014] Preferably, the drive mechanism includes a hydraulic cylinder hinged to the base, with one end of the hydraulic cylinder away from the base hinged to the frame.

[0015] Preferably, the base is provided with a horizontal support seat and a vertical support seat. The horizontal support seat is used to support the frame when the frame is in a horizontal position; the vertical support seat is used to support the frame when the frame is in an upright position.

[0016] Preferably, the frame includes two longitudinal beams and two slewing bearings, with the two ends of the two longitudinal beams fixedly connected to the outer rings of the two slewing bearings, and the two ends of the drying cylinder disposed on the inner rings of the two slewing bearings.

[0017] Preferably, a motor is fixed on one of the frames, a gear ring is fitted on the outer wall of the drying cylinder, and the output shaft of the motor is connected to the gear ring via a reduction gearbox.

[0018] The beneficial effects of this utility model are as follows:

[0019] The drying cylinder of this invention is rotatably mounted on a frame, which can rotate around the hinge axis between the frame and the base via a drive mechanism, thus switching the drying cylinder between a horizontal and a vertical state. The drying cylinder contains multiple first partitions and multiple second partitions. In the horizontal state, the second partitions can rotate, aligning the notches on the first partitions with the notches on the second partitions. The drying cylinder can then rotate on the frame, with the notches facing downwards, allowing the distiller's grains poured into the drying cylinder to spread evenly on the side wall of the drying cylinder through the notches. The drying cylinder then rotates again, with the notches facing upwards, allowing the first and second partitions to separate the distiller's grains. When the drive mechanism converts the drying cylinder to a vertical state, the distiller's grains are vertically separated into different levels of partitions. When the second partition rotates again, causing the gaps between the first and second partitions to be misaligned, an S-shaped airflow channel is formed inside the drying cylinder. The hot air entering from the air inlet must pass through all the gaps before it can be discharged from the air outlet. During this process, the distiller's grains spread on the first and second partitions are dried at a low temperature. Because the distiller's grains are relatively evenly separated on different partitions, the contact area between the distiller's grains and the hot air is greatly increased, improving the drying efficiency. By setting splines at both ends of the inner shaft and setting springs between the limiting ring and the limiting seat for buffering, a vibration motor can be installed on one of the second partitions to make the first and second partitions vibrate, causing the distiller's grains to jump on the partitions, thereby further promoting the contact between the distiller's grains and the hot air and improving the drying effect.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Example 1:

[0034] like Figures 1 to 9As shown, Embodiment 1 of this utility model provides a low-temperature treatment device for distillers' lees feed, used for low-temperature drying of distillers' lees feed to reduce its moisture content. The device mainly includes a base 1, a frame 2 hinged to the base 1 via a hinge shaft, and a drying cylinder 3 rotatably mounted in the frame 2. The device has two working states. In the initial state, the drying cylinder 3 is in a horizontal position, where the horizontal support seat 22 fixed to the base 1 supports the frame 2. To transform the device into an upright position, this utility model designs a drive mechanism, including a hydraulic cylinder 21. One end of the hydraulic cylinder 21 is hinged to the base 1, and the other end is hinged to the frame 2. When the device is in the initial state, the hydraulic cylinder 21 is in a retracted state. When the device needs to be transformed into an upright state, the hydraulic cylinder 21 extends, pushing the frame 2 to rotate 90° around the hinge shaft, so that the drying cylinder 3 is in an upright state. At this time, the upright support seat 23 fixed to the base 1 supports the frame 2.

[0035] like Figure 1 As shown, the top of the drying cylinder 3 has a feed inlet 4 and an air inlet 5, and the bottom of the drying cylinder 3 has a discharge outlet 6, with an air outlet 7 on one side of the bottom. The feed inlet 4, air inlet 5, air outlet 7, and discharge outlet 6 are all equipped with solenoid valves (not shown in the attached diagram). A dryer (not shown in the diagram) is fixed to the side wall of the drying cylinder 3, and the dryer can supply dry hot air to the air inlet 5. Figure 4 and Figure 6 As shown, multiple first partitions 8 and multiple second partitions 9 are arranged inside the drying cylinder 3. The first partitions 8 and second partitions 9 are parallel and are arranged alternately, that is, the two sides of the second partitions 9 are the first partitions 8. The outer diameters of the first partitions 8 and second partitions 9 are adapted to the inner diameter of the drying cylinder 3, but both the first partitions 8 and second partitions 9 have notches 10.

[0036] like Figure 4 and Figure 6 As shown, the notches 10 on the first partition 8 and the second partition 9 have two matching methods. When the drying cylinder 3 is in a horizontal position, the notches 10 on the second partition 9 can be adjusted to align with the notches 10 on the first partition 8. Since the drying cylinder 3 can rotate on the frame 2, all the notches 10 can face downwards. At this time, distiller's grains are poured into the drying cylinder 3. Under the influence of gravity, the distiller's grains slide along the notches 10 and are distributed relatively evenly on the side wall of the drying cylinder 3. When the drying cylinder 3 rotates again and the position of the notches 10 gradually increases, the first partition 8 and the second partition 9 can separate the distiller's grains, which are then divided into several parts relatively evenly. At this time, the hydraulic cylinder 21 can be extended to turn the drying cylinder 3 into an upright position.

[0037] At this point, the second partition 9 is rotated again, so that the notch 10 on the second partition 9 faces the opposite direction to the notch 10 on the first partition 8. This forces the hot air entering the drying cylinder 3 from the air inlet 5 to repeatedly change direction in an S-shape as it passes through the notches 10 of each partition. This allows the hot air to flow over the distiller's grains on the partition before entering the next partition, and finally, the hot air is discharged from the air outlet 7, achieving low-temperature and uniform drying of the distiller's grains. The dried distiller's grains are discharged from the discharge outlet 6.

[0038] Example 2:

[0039] Based on Embodiment 1, the frame 2 designed in this utility model includes two longitudinal beams 24 and two slewing bearings 25, as shown below. Figure 1 As shown, the two ends of the longitudinal beam 24 are fixedly connected to the outer rings of the two slewing bearings 25, while the inner rings of the slewing bearings 25 are fitted onto the drying cylinder 3. The axes of the two slewing bearings 25 are collinear, thus giving the drying cylinder 3 the freedom to rotate on the frame 2.

[0040] To facilitate the rotation of the drying cylinder 3 on the frame 2, a motor 26 is fixed on the longitudinal beam 24. The output shaft of the motor 26 is connected to a reduction gearbox, and a gear ring 27 is fixedly sleeved on the outer wall of the drying cylinder 3. The reduction gearbox is equipped with a gear that meshes with the gear ring 27. Therefore, the rotation angle of the drying cylinder 3 can be controlled by driving the gear ring 27 to rotate through the motor 26.

[0041] Example 3:

[0042] Based on Embodiments 1 and 2, this utility model proposes Embodiment 3, in which a specific configuration of an adjustment mechanism capable of driving the second partition 9 to rotate is presented. For example... Figure 6 and Figure 7 As shown, limit seats 13 are rotatably mounted on the top and bottom of the drying cylinder 3 via bearing seats. The adjusting mechanism includes an inner shaft 11 and an outer shaft 12. The inner shaft 11 has splines at both ends, and is movably inserted into the two limit seats 13 via the splines at both ends. The outer shaft 12 is sleeved on the inner shaft 11. Figure 8 and Figure 9 As shown, the outer shaft 12 has multiple clearance grooves 19 for engaging the second partition 9, and the inner shaft 11 has a connecting block 20 fixed at the position corresponding to the clearance grooves 19, the connecting block 20 extending out of the clearance grooves 19. The second partition 9 is fixed to the connecting block 20. The connecting block 20 has a rotational space of 180° within the clearance grooves 19. Therefore, the inner shaft 11 can rotate 180° relative to the outer shaft 12. The first partition 8 is fixed to the outer shaft 12, so that in the initial state, the notches 10 of the first partition 8 and the second partition 9 face the same direction; when the outer shaft 12 does not rotate while the inner shaft 11 rotates 180 degrees, the notches 10 on the first partition 8 and the second partition 9 can be made to face opposite directions.

[0043] Since the inner shaft 11 and the limiting seat 13 are splined, a gear ring can be fitted onto the limiting seat 13 at the bottom of the drying cylinder 3. Then, another motor is fixedly installed at the bottom of the drying cylinder 3. The motor drives the gear ring to rotate, thereby driving the inner shaft 11 to rotate. To prevent the outer shaft 12 from rotating when the inner shaft 11 rotates, a key bar 17 is fixed on the drying cylinder 3, and a keyway 18 is made on the outer shaft 12. The key bar 17 can slide in the keyway 18, which allows the outer shaft 12 to move axially together with the inner shaft 11, but the outer shaft 12 is restricted by the key bar 17 and cannot rotate.

[0044] Example 4:

[0045] Based on Examples 1 to 3, in order to make the distiller's grains feed more evenly distributed on the first partition 8 and the second partition 9, as follows: Figure 7 As shown, in this embodiment, a limiting ring 14 is fitted onto the inner shaft 11, and a spring 15 is fitted onto the inner shaft 11 between the limiting ring 14 and the limiting seat 13. This allows the inner shaft 11 to be cushioned by the spring 15. Considering that relative rotation may occur between the inner shaft 11 and the outer shaft 12, a nylon ring 16 is fitted onto the inner shaft 11 between the limiting ring 14 and the outer shaft 12, with the outer shaft 12 abutting against the nylon ring 16 to reduce rotational wear between the inner shaft 11 and the outer shaft 12. A vibration motor 26 can be fixedly installed on the inner shaft 11, the outer shaft 12, or any of the first partition 8 or the second partition 9. The spring 15 can dampen the impact, while the vibration motor 26 causes the first partition 8 and the second partition 9 to vibrate, lifting the distiller's grains and increasing the contact area with hot air, thus improving the drying effect.

[0046] After drying is complete, the adjusting mechanism drives the inner shaft 11 to rotate, so that the notch 10 of the second partition 9 is aligned with the notch 10 of the first partition 8 again, forming a material channel. The oil cylinder 21 retracts, causing the drying cylinder 3 to tilt, and the distillers' grains slide from the first partition 8 and the second partition 9 into the material channel, and finally are discharged from the discharge port 6.

[0047] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
