Abstract
Description
Technical Field
[0001] This utility model belongs to the field of sucralose production technology, specifically a sucralose granulation device. Background Technology
[0002] Sucralose, commonly known as sucralose, is a high-intensity sweetener. It is a sucrose derivative obtained through chemical modification of sucrose. During the production of sucralose, granulation is required, and the current granulation method uses a fluidized bed granulator.
[0003] During the granulation process, it is necessary to monitor the granulation progress by observation. The existing method is to set up an observation port on the fluidized bed granulator for observation. However, the observation port is prone to blurring, resulting in poor observation and making it impossible to accurately judge the granulation progress. Utility Model Content
[0004] This invention provides a sucralose granulation device to overcome the deficiencies in the prior art.
[0005] This utility model is achieved through the following technical solution:
[0006] A sucralose granulation device includes an outer tube inserted into the lower part of the side wall of a fluidized bed granulator furnace. The inner end of the outer tube is closed, while the outer end is open to the outside. A first feed chute located inside the furnace is opened on the side of the outer tube. A slider that closes the first feed chute is slidably fitted inside the outer tube. The slider and the outer tube are slidably sealed. The slider is fixedly connected to the inner wall of the inner end of the outer tube by a spring. An inner tube that is closed at both ends is slidably fitted inside the outer tube. A through groove that communicates with the first feed chute is opened on the side of the inner tube. A pull rod is connected to the inner tube and extends out of the outer tube.
[0007] In use, the fluidized bed granulator first blows the granules upwards using airflow. A pull rod pushes the inner tube, causing it to press against the slider, which in turn moves the slider away from the first feed chute, aligning the through-channel with the feed chute. As the airflow blows the granules, some granules pass through the first feed chute and through-channel into the inner tube. Then, the pull rod is pulled, moving the inner tube away from the slider. The slider, under the action of a spring, continues to seal the first feed chute, pulling the inner tube out. This allows the granules to be poured out of the through-channel, and the granulation progress can be accurately monitored by observing the condition of the poured-out granules.
[0008] Preferably, the outer tube is rotatably connected to the side wall of the furnace body via a sealed damping bearing, and a rotating arm located outside the furnace body is fixedly connected to the side of the outer tube. This allows the outer tube to rotate so that when sampling is not required, the opening of the first feed chute faces the correct direction, preventing material from being fed into the first feed chute and ensuring accurate observation.
[0009] Preferably, the outer tube is further provided with a second feeding groove, which is located inside the outer tube and on the same horizontal line as the first feeding groove. The front end of the inner tube is fixedly connected to an upward-opening receiving groove, located below the slider. A sealing block that closes the second feeding groove is fixedly connected to the back of the slider via a connecting rod. When the first feeding groove is opposite to the through groove, the second feeding groove is opposite to the receiving groove. The sealing block is fixedly connected to a spring. Pushing the inner tube causes the receiving groove to move from below the slider, and the slider moves under the action of the inner tube. The movement of the slider causes the sealing block to move synchronously, thus making the first feeding groove and the second feeding groove vertically opposite to the through groove and the receiving groove, respectively, achieving sampling from two areas and ensuring accurate detection. When the inner tube moves away from the slider, the sealing block and the slider return to their original positions under the action of the spring.
[0010] Preferably, a horizontal tube is vertically connected to the inner wall of the outer tube, and a horizontal shaft is slidably fitted inside the horizontal tube. The horizontal shaft is fixedly connected to the inner wall of the horizontal tube by a spring, and the outer end of the horizontal shaft is vertically connected to the sealing block. Under the action of the horizontal tube and the horizontal shaft, the spring is ensured to compress laterally, achieving better force distribution.
[0011] Preferably, both the first and second feed troughs are tapered structures that are wider on the outside and narrower on the inside, thereby reducing the width of the closed section while meeting the feeding width requirement. This reduces the overall thickness of the slider and sealing block, and thus reduces friction.
[0012] Preferably, the furnace body sidewall has a through hole, the outer tube passes through the through hole and is rotatably connected to the through hole through a sealed damping bearing, and a baffle is fixedly connected inside the through hole. The baffle has a circular hole with a diameter consistent with the outer diameter of the outer tube, and the outer tube passes through the circular hole. The baffle can prevent particles from entering the sealed damping bearing and affecting its normal use.
[0013] Preferably, the outer tube has an internal thread at its outer end, and a rotating disk that mates with the internal thread is fixedly sleeved on the pull rod. The pull rod and the inner tube are rotatably connected via bearings. The threaded connection between the outer tube and the rotating disk allows for better pulling out of the inner tube.
[0014] Preferably, the inner end of the outer tube is located at the observation port, and a rotating handle is fixedly provided at the outer end of the pull rod. The inner end of the outer tube being located at the observation port allows for a rough observation of whether the first and second feed troughs are facing downwards, while the rotating handle facilitates the rotation of the pull rod.
[0015] The beneficial effects of this utility model are as follows: the use of this application can realize the collection of a certain amount of particles through the first feeding trough and the pulling out through the inner tube, thereby accurately judging the progress of granulation. At the same time, the setting of the second feeding trough can increase the comparison ratio and improve the accuracy of judgment. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0023] A sucralose granulation device, such as Figures 1-3 As shown, the system includes an outer tube 3 that penetrates the lower part of the side wall of the fluidized bed granulator furnace body 1. The inner end of the outer tube 3 is closed, while the outer end is open to the outside. A first feed chute 5 located inside the furnace body 1 is opened on the side of the outer tube 3. A slider 8 that closes the first feed chute 5 is slidably fitted inside the outer tube 3, and the slider 8 is slidably sealed to the outer tube 3. The slider 8 is fixedly connected to the inner wall of the inner end of the outer tube 3 by a spring 13. An inner tube 4 that is closed at both ends is slidably fitted inside the outer tube 3. A through groove that communicates with the first feed chute 5 is opened on the side of the inner tube 4. A pull rod 10 is connected to the inner tube 4 and extends out of the outer tube 3. The outer tube 3 is rotatably connected to the side wall of the furnace body 1 by a sealed damping bearing, and a rotating arm located outside the furnace body 1 is fixedly connected to the side of the outer tube 3.
[0024] In use, the fluidized bed granulator first blows the granules upwards using airflow. The inner tube 4 is pushed by the pull rod 10, causing it to press against the slider 8. This moves the slider 8 away from the first feed chute 5, and the through-channel is opposite to the feed chute. As the airflow blows the granules, some granules enter the inner tube 4 through the first feed chute 5 and the through-channel. Then, the pull rod 10 is pulled, moving the inner tube 4 away from the slider 8. The slider 8, under the action of the spring 13, continues to seal the first feed chute 5, pulling out the inner tube 4. This allows the granules to be poured out of the through-channel, and the granulation progress can be accurately monitored by observing the condition of the poured-out granules.
[0025] When the outer tube 3 is rotated by the sealed damping bearing, the outer tube 3 can be fixed. At the same time, rotating the outer tube 3 ensures that the opening of the first feed trough 5 faces the same direction when sampling is not required, thus avoiding feeding material into the first feed trough 5 and ensuring accurate observation.
[0026] The outer tube 3 is also provided with a second feeding groove 6. The second feeding groove 6 is located inside the outer tube 3 and is on the same horizontal line as the first feeding groove 5. The front end of the inner tube 4 is fixedly connected to a receiving groove 7 with an upward opening. The receiving groove 7 is located below the slider 8. The back of the slider 8 is fixedly connected to a sealing block 9 that closes the second feeding groove 6 through a connecting rod. When the first feeding groove 5 is opposite to the through groove, the second feeding groove 6 is opposite to the receiving groove 7. The inner wall of the inner end of the outer tube 3 is vertically connected to a horizontal tube. A horizontal shaft 12 is slidably fitted inside the horizontal tube. The horizontal shaft 12 is fixedly connected to the inner wall of the horizontal tube through a spring 13. The outer end of the horizontal shaft 12 is vertically connected to the sealing block 9.
[0027] The inner tube 4 is pushed, causing the receiving groove 7 to move from below the slider 8. The slider 8 moves under the influence of the inner tube 4, and the movement of the slider 8 causes the sealing block 9 to move synchronously. This makes the first feeding groove 5 and the second feeding groove 6 vertically opposite the through groove and the receiving groove 7, respectively, enabling sampling from two areas and ensuring accurate testing. When the inner tube 4 moves away from the slider 8, the sealing block 9 and the slider 8 return to their original positions under the action of the spring 13. The horizontal tube and the horizontal shaft 12 ensure that the spring 13 provides lateral compression, achieving better force distribution.
[0028] The first feed trough 5 and the second feed trough 6 are both tapered structures that are wider on the outside and narrower on the inside. This reduces the width of the closed part while meeting the feeding width requirement, thereby reducing the overall thickness of the slider 8 and the sealing block 9, and thus reducing friction.
[0029] The furnace body 1 has a through hole on its side wall. The outer tube 3 passes through the through hole and is rotatably connected to the through hole through a sealed damping bearing. A baffle 14 is fixedly connected inside the through hole. The baffle 14 has a circular hole with a diameter consistent with the outer diameter of the outer tube 3. The outer tube 3 passes through the circular hole. The baffle 14 can prevent particles from entering the sealed damping bearing and affecting its normal use.
[0030] The outer tube 3 has an internal thread at its outer end, with the inner diameter of the thread matching the outer diameter of the inner tube. A rotating disk 11, which mates with the internal thread, is fixedly fitted onto the pull rod 10. The pull rod 10 and the inner tube 4 are rotatably connected via bearings. The threaded connection between the outer tube 3 and the rotating disk 11 allows for better pulling out of the inner tube 4, while also preventing the pull rod from moving unintentionally and avoiding dust entering the outer and inner tubes.
[0031] The inner end of the outer tube 3 is located at the observation port 2, and a rotating handle is fixedly installed at the outer end of the pull rod 10. The inner end of the outer tube 3 being located at the observation port 2 allows for a rough observation of whether the first feed trough 5 and the second feed trough 6 are facing downwards, while the rotating handle facilitates the rotation of the pull rod 10.
[0032] The use of this application enables the collection of a certain amount of particles through the first feed trough 5 and their extraction through the inner tube 4, thereby accurately determining the progress of granulation. At the same time, the setting of the second feed trough 6 increases the comparison ratio and improves the accuracy of the judgment.
[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
