Description
Technical Field
[0001] This utility model belongs to the field of distillery lees processing technology, specifically relating to a cooling device and production line for distillery lees. Background Technology
[0002] In related technologies, the lees processing line typically includes steps such as lees production, collection, preliminary treatment (such as drying), and subsequent storage or reuse.
[0003] In some existing technologies, the lees processing production line is not equipped with a dedicated device for cooling the lees. This results in the lees being at a high temperature after drying. If they are packaged or stored directly, it may cause mold or other quality problems, affecting the product's shelf life and quality. In other existing technologies, some production lines attempt to use natural cooling or simple ventilation systems as alternatives. However, these methods are often time-consuming and cannot meet the rapid turnover requirements of large-scale production. Furthermore, it is difficult to ensure uniform cooling, which can easily lead to localized overheating or insufficient cooling. Utility Model Content

[0012] Furthermore, among the multiple conveying groups, the conveying groups located at both ends of the axial direction are extended conveying groups, and the two extended conveying groups correspond to the two fixed cylinders respectively.

[0034] Example 1:
[0035] like Figures 1-3 As shown, this utility model provides a cooling device 1 for distiller's grains, including: a base 10, a rotating drum 20, a fixed drum 30, and a ventilation pipe 40. The rotating drum 20 is rotatably disposed on the top of the base 10. There are two fixed drums 30, which are respectively fixedly connected to the base 10. The two fixed drums 30 are respectively disposed at both ends of the rotating drum 20 in the axial direction. The top of one fixed drum 30 is provided with a feed inlet 31, and the bottom of the other fixed drum 30 is provided with a discharge outlet. The ventilation pipe 40 is connected to the top of at least one fixed drum 30. The rotating drum 20 rotates to transport the distiller's grains in one fixed drum 30 to the other fixed drum 30.
[0036] In some embodiments, the base 10 serves as the basic structure of the entire cooling device 1. The base 10 is connected to the ground to provide support. The rotating drum 20 is rotatably mounted on the top of the base 10. The rotating drum 20 is a key component for material conveying. The rotating drum 20 pushes the lees from one position to another by rotating. Two fixed drums 30 are designed. The two fixed drums 30 are fixedly connected to the base 10 and located at the two ends of the rotating drum 20 in the axial direction. One of the fixed drums 30 is provided with a feed inlet 31 at the top for feeding in the lees to be cooled. The other fixed drum 30 is provided with a discharge outlet at the bottom for discharging the cooled lees. At least one fixed drum 30 is connected to a ventilation pipe 40 at the top. The hot air from the lees in the fixed drum 30 and the rotating drum 20 can be discharged through the ventilation pipe 40 to assist the cooling process.
[0037] Understandably, when the rotating drum 20 rotates, it will gradually push the lees from one of the fixed drums 30 that enter from the feed inlet 31 into the other fixed drum 30. During this process, the lees will tumble as the rotating drum 20 rotates. During the tumbling process, the heat from the lees will be rapidly dissipated into the fixed drum 30 and the rotating drum 20. The heat from the fixed drum 30 and the rotating drum 20 will be discharged through the ventilation pipe 40 to achieve the purpose of cooling.
[0038] It is worth mentioning that by controlling the rotation speed of the drum 20, the residence time of the lees in the cooling device 1 can be effectively managed to ensure that the lees are fully cooled.
[0039] According to the present invention, the cooling device 1 for distiller's grains, by setting up a rotating drum 20 and a ventilation pipe 40, allows the cooling rate of the distiller's grains during the processing to be faster, thereby reducing the time spent waiting for the distiller's grains to cool down and accelerating the processing efficiency of the distiller's grains.
[0040] Example 2:
[0041] Based on Embodiment 1, this embodiment has multiple flaps spaced apart in the circumferential direction on the inner peripheral wall of the rotating drum 20. The rotating drum 20 rotates to drive the multiple flaps to rotate, and the multiple flaps rotate to drive the lees to move axially.
[0042] Understandably, multiple flaps are installed on the inner circumferential wall of the rotating drum 20. These flaps are not continuous but are spaced apart along the circumference of the drum 20 to effectively agitate and propel the lees. When the drum 20 begins to rotate, the flaps also rotate. Due to the friction between the flaps and the lees, as well as the design shape of the flaps (usually with a certain inclination angle), the lees can be gradually pushed to the other end inside the drum 20.
[0043] It's worth noting that the rotating flap also causes the lees to move circumferentially. When the lees reach a high point, they fall under gravity. During this fall, the lees have a larger contact area with the air, and the falling speed allows for faster heat dissipation, resulting in a faster cooling rate. Furthermore, the rotation of the flap ensures the even distribution of the lees within the rotating drum 20, preventing localized accumulation or uneven cooling. Specifically, the flap continuously turns and pushes the lees, increasing their contact with air and thus improving the cooling effect.
[0044] According to some embodiments of this utility model, the flapper is spirally shaped. Specifically, the flapper is designed in a spiral shape, with the flappers arranged spirally along the inner wall of the rotating drum 20. This allows the flapper to not only push the material axially when the rotating drum 20 rotates, but also to simultaneously perform a stirring action (so that the rotating drum 20 can form a structure similar to a concrete mixer and have the function of a concrete mixer). That is, the flapper also agitates the lees during rotation, ensuring that the lees are fully mixed during cooling, which helps to dissipate heat more evenly, thereby improving the cooling efficiency and uniformity of the lees.
[0045] Preferably, the multiple flaps spaced circumferentially constitute a conveying group, and there are multiple conveying groups. A temporary storage space is defined between two adjacent conveying groups. The rotating drum 20 rotates and has a first speed and a second speed. At the first speed, the lees are located in the temporary storage space. At the second speed, the rotating drum 20 can transport the lees in one adjacent temporary storage space to another adjacent temporary storage space.
[0046] In some embodiments, the first rotational speed is less than the second rotational speed. At the first rotational speed, the drum 20 rotates slowly, and the lees fall into the temporary storage space under the action of gravity, and during this period, they are in full contact with the air so that the heat of the lees can be fully dissipated. At the second rotational speed, the drum 20 rotates faster to move the lees from one temporary storage space to the next. At this time, the spiral flap acts as a conveying component, effectively pushing the lees forward, so that the lees can move forward step by step in the cooling device 1, from the feed inlet 31 to the discharge outlet.
[0047] Understandably, by controlling the rotation speed, it is possible to ensure that the lees are sufficiently cooled while avoiding uneven cooling caused by moving too fast. Moreover, the operating mode can be adjusted according to actual needs, allowing for both prolonged stays to ensure deep cooling and rapid material transfer to speed up the overall processing.
[0048] Of course, during the switching of different speeds, the lees can not only be fully cooled, but also achieve better mixing and distribution under the action of the flip plate, which helps to improve the quality of the final product. At the same time, the time ratio of the first speed and the second speed can be flexibly adjusted according to different production needs to adapt to diverse process requirements.
[0049] Example 3:
[0050] Based on Embodiment 2, in this embodiment, among the multiple conveying groups, the conveying groups located at both ends of the axial direction are extended conveying groups. The two extended conveying groups correspond to the two fixed cylinders 30 respectively, and the multiple flaps of the extended conveying groups extend into the corresponding fixed cylinders 30 respectively.
[0051] In some embodiments, when the cooling device 1 is in operation, the extended conveyor group located at the feed end can effectively collect the lees fed from the feed inlet 31 through its flaps extending into the fixed cylinder 30, and gradually guide them into the rotating drum 20, so as to help avoid material accumulation at the inlet of the fixed cylinder 30 and ensure smooth material flow. Similarly, at the discharge end, the extended conveyor group ensures that the lees that have completed the cooling process can be smoothly transferred from the rotating drum 20 to the fixed cylinder 30 where the discharge outlet is located, and finally discharged out of the cooling device 1. That is, since the flaps extend into the fixed cylinder 30, the flaps can directly contact and push the lees near the discharge outlet when the rotating drum 20 rotates, thereby improving the discharge efficiency.
[0052] Thus, by extending the flap into the interior of the fixed cylinder 30, the material transfer capacity during the feeding and discharging stages is enhanced, the possibility of material residue is reduced, and it also helps to keep the interior of the cooling device 1 clean.
[0053] According to some embodiments of the present invention, the multiple flaps of the extended conveying group have a gap d between them and the inner peripheral wall of the fixed cylinder 30, satisfying: 1mm≤d≤1.8mm.
[0054] In some embodiments, by avoiding direct contact between the flap and the inner wall of the fixed cylinder 30, wear between mechanical parts is reduced, thereby extending the service life of the cooling device 1. Moreover, although there is a gap between the flap and the inner peripheral wall of the fixed cylinder 30, the gap size is very small (1mm to 1.8mm), which prevents the lees from passing through the gap, so that the flap rotation can smoothly drive the lees to move.
[0055] It is worth mentioning that by setting 1mm≤d≤1.8mm, it can be ensured that the material will not easily get stuck or stagnant, making the entire cooling process smoother and more reliable, and also facilitating regular cleaning and maintenance.
[0056] Example 4:
[0057] Based on Embodiment 1, this embodiment has a gear ring 21 on the outer peripheral wall of the rotating drum 20, a rotating motor 50 fixedly mounted on the base 10, and a drive gear 51 coaxially mounted on the output shaft of the rotating motor 50, which meshes with the gear ring 21.
[0058] It is understandable that when the rotating motor 50 is started, the output shaft of the rotating motor 50 drives the drive gear 51 to rotate. Since the drive gear 51 is tightly meshed with the gear ring 21 on the rotating drum 20, this will cause the gear ring 21 to rotate, thereby driving the entire rotating drum 20 to rotate.
[0059] It is worth mentioning that the rotation speed of the drum 20 (such as the first speed and the second speed) can be precisely controlled by adjusting the speed of the rotating motor 50 or by using a gearbox or other devices to meet different operational requirements (such as different stages in the material conveying or cooling process).
[0060] According to some embodiments of the present invention, a first mating ring 32 is provided at one end of the fixed cylinder 30 facing the rotating cylinder 20, and a second mating ring 22 is provided on the side of the rotating cylinder 20 facing the fixed cylinder 30. The first mating ring 32 and the second mating ring 22 are rotatably mated. A support rotating wheel 11 is rotatably provided on the base 10. The support rotating wheel 11 is constructed as two wheels spaced apart in the width direction. The outer peripheral wall of the support rotating wheel 11 is provided with a rotating groove 111 extending in the circumferential direction. Parts of the first mating ring 32 and the second mating ring 22 are located in the rotating groove 111 of the two support rotating wheels 11.
[0061] In some embodiments, a first mating ring 32 is disposed at one end of the fixed cylinder 30 facing the rotating cylinder 20, and a second mating ring 22 is located on the side of the rotating cylinder 20 facing the fixed cylinder 30. The first mating ring 32 and the second mating ring 22 are designed to be able to rotate freely relative to each other, so as to allow the rotating cylinder 20 to rotate relative to the fixed cylinder 30. The support rollers 11 are rotatably mounted on the base 10, and two support rollers 11 are arranged at intervals in the width direction (i.e., the two support rollers 11 are distributed at intervals in the circumferential direction of the first mating ring 32). The outer peripheral wall of each support roller 11 is provided with a rotating groove 111 extending in the circumferential direction. Parts of the first mating ring 32 and the second mating ring 22 are embedded in the rotating grooves 111 of the two support rollers 11 to achieve stable support and smooth rotation of the rotating cylinder 20.
[0062] Understandably, the support wheel 11 and its rotating groove 111 provide physical support for the first mating ring 32 and the second mating ring 22, and guide the first mating ring 32 and the second mating ring 22 to move along a predetermined path (i.e., the rotating groove 111), which not only ensures the stability of the rotating drum 20, but also reduces frictional resistance, making the rotation smoother.
[0063] It is worth mentioning that the two inner walls of the rotating groove 111 can respectively restrict the two side walls of the first mating ring 32 and the second mating ring 22 that are away from each other, so as to prevent the first mating ring 32 and the second mating ring 22 from moving relative to each other in the axial direction during the rotation of the rotating drum 20, thereby improving the sealing effect between the first mating ring 32 and the second mating ring 22, and thus ensuring the sealing effect between the rotating drum 20 and the fixed drum 30.
[0064] Preferably, a limiting protrusion is provided on the side of the first mating ring 32 facing the second mating ring 22, and a circular groove 321 is provided on the side of the second mating ring 22 facing the first mating ring 32. The limiting protrusion is movably received in the circular groove 321, which can further improve the sealing effect between the fixed cylinder 30 and the rotating cylinder 20.
