Description

Technical Field

[0001] This invention relates to the field of aspartame recovery equipment technology, and particularly to an aspartame production mother liquor recovery and treatment device and process. Background Technology

[0002] Aspartame, a common sweetener, is widely used in food processing and pharmaceutical production. The production process involves mixing raw materials in specific proportions to form an aspartame mother liquor, followed by crystallization, filtration, and drying to produce the finished aspartame product. To recover the aspartame mother liquor and avoid waste, a dedicated recycling system is required to collect and process any remaining liquid.

[0003] Most common aspartame mother liquor recovery and treatment devices involve thoroughly mixing the aspartame mother liquor with resins that can adsorb aspartame and other substances, allowing for the adsorption and recovery of components from the mother liquor. While these common recovery devices generally achieve good recovery results, some problems still exist:

[0004] 1. Common aspartame mother liquor recovery devices require long-term stirring to ensure that the resin particles can fully adsorb the liquid. After full absorption, the resin particles also need to be dried to evaporate the mother liquor, resulting in low recovery efficiency.

[0005] 2. When recycling common aspartame mother liquor, some sediment is present in the mother liquor, which can easily leave residue at the bottom of the device after the treated mother liquor is discharged, making cleaning inconvenient. Summary of the Invention

[0006] The purpose of this invention is to provide an aspartame production mother liquor recovery and treatment device and process to solve the problem of limited recovery efficiency of existing aspartame mother liquor.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an aspartame production mother liquor recovery and treatment device and process, comprising a main frame and a top cover, wherein diversion pipes are installed on both sides of the main frame, nozzles are installed on both sides of the inner sidewall of the main frame, a top cover is installed on the top of the main frame, a storage tank is installed inside the main frame, a drain port is provided at the bottom of one side of the main frame, a rotating disk is rotatably connected to the bottom of the inside of the main frame, a drive motor is installed at the bottom of the main frame, a material rack is installed inside the storage tank, and a stabilizing structure is provided at the bottom of the top cover, the stabilizing structure including a pressing plate and an inlay. The storage container includes a groove, rollers, a limiting seat, a guide groove, an insert block, a docking plate, a docking groove, a guide block, and a pressing spring. The pressing plate is installed at the top of the storage container. An insert groove is formed inside the bottom of the pressing plate. A roller is rotatably connected to the inside of the outer wall of the pressing plate. A limiting seat is fixedly connected to the top of the pressing plate. A guide groove is formed inside the outer wall of the limiting seat. An insert block is slidably connected inside the limiting seat. A docking plate is rotatably connected to the top of the insert block. A docking groove is formed inside the bottom of the top cover. A guide block is fixedly connected to the bottom of the outer wall of the insert block. A pressing spring is fixedly connected to the bottom of the insert block. The pressing spring... Under the action of elasticity, the rotating disk is pushed upward, causing the docking plate to embed into the docking groove, thereby making the rotation of the storage bin more stable. An auxiliary structure is fixedly connected to the top of the rotating disk. This auxiliary structure includes a positioning groove, a socket, a sliding groove, a return spring, a positioning block, an anti-slip groove, a slider, and a paddle. The positioning groove is located at the bottom of the outer wall of the storage bin. A socket is fixedly connected to the top of the rotating disk. A sliding groove is formed on the inner side wall of the socket. A return spring is fixedly connected to one side of the sliding groove. A positioning block is fixedly connected to one side of the return spring. An anti-slip groove is formed on one side of the positioning block. Slider blocks are fixedly connected to one side of both ends of the positioning block. A lever is fixedly connected to one side of the top of the positioning block. By moving the lever in the opposite direction, the positioning block can be removed from the positioning groove, and the storage bucket can be pulled upwards. The bottom of the rotating disk is provided with a cleaning structure, which includes an installation groove, a slot, a support plate, a scraper, a snap-fit ​​spring, and a locking block. The installation groove is opened inside the bottom of the rotating disk, and a slot is opened at the top of the installation groove. A support plate is installed inside the installation groove, and a scraper is fixedly connected to the bottom of the support plate. Snap-fit ​​springs are provided on one side of both ends of the support plate, and a locking block is fixedly connected to the top of the support plate. When the rotating disk rotates continuously, the scraper will scrape away the dirt inside the bottom of the main frame.

[0008] In use, resin particles that can adsorb the corresponding components in the aspartame mother liquor are sequentially placed into the various trays of the carrier rack. The carrier rack containing the resin particles is then inserted into the storage bucket. Several storage buckets are then installed on top of the rotating disk, and the top cover is closed. The aspartame mother liquor is sprayed from the nozzle towards the storage bucket through a diversion pipe on one side. At the same time, the drive motor is started to make the rotating disk rotate at a constant speed, thereby rotating the storage bucket. This allows the nozzle to evenly spray the aspartame mother liquor onto the resin inside each storage bucket, so that the resin can quickly adsorb the corresponding substances in the aspartame mother liquor. When a certain volume of aspartame mother liquor has been injected, the injection is stopped, and the rotating storage bucket continues to adsorb the corresponding substances in the aspartame mother liquor. Over time, when the resin is saturated, the drain port is opened to discharge the waste liquid. The top cover is then opened, and the carrier rack is removed from the inside of the storage bucket, along with the saturated resin particles. This completes the recovery of the corresponding substances in the aspartame mother liquor.

[0009] Preferably, the inlay grooves are arranged in a ring shape inside the bottom end of the pressing plate, and the inlay grooves are inlaid with the top of the outer wall of the storage bucket, so as to make the rotation of the storage bucket more stable.

[0010] Preferably, the guide groove and the guide block have a sliding structure, and the docking plate and the docking groove have an embedded structure.

[0011] Preferably, the positioning groove and the positioning block are inlaid, and the sockets are distributed in a ring at the top of the rotating disk, so as to make the rotation of the storage bucket more stable.

[0012] Preferably, the positioning block has a sliding structure inside the groove via a slider, and the anti-slip grooves are evenly distributed on one side of the positioning block.

[0013] Preferably, the mounting grooves are arranged in a ring shape inside the bottom of the rotating disk, the mounting grooves and the support plate are inlaid, the slots and the blocks are engaged, and the slots and the snap-on springs are engaged, so as to avoid excessive dirt that is difficult to clean.

[0014] An apparatus and process for recovering and treating mother liquor from aspartame production includes the following steps:

[0015] S1. Loading: Place the resin particles that can adsorb the corresponding substances in aspartame into the material carrier in sequence, and then insert the material carrier into the inside of the storage bucket for installation;

[0016] S2. Install the top cover: Insert the storage bucket containing resin granules into the socket at the top of the rotating disk, and put the top cover on the top of the main frame to keep the storage bucket stable under the action of the stabilizing structure and auxiliary structure.

[0017] S3. Start-up and Injection: Start the drive motor to make it rotate the storage tank at a constant speed through the rotating plate, and spray the aspartame mother liquor into the storage tank through the nozzle. Stop the injection when the mother liquor inside the main frame reaches a certain volume.

[0018] S4. Adsorption reaction: As the storage tank rotates and the aspartame mother liquor is injected, the resin particles rapidly adsorb the corresponding substances in the aspartame mother liquor.

[0019] S5. Discharge: After the resin particles have been fully adsorbed, open the drain port to discharge the waste liquid;

[0020] S6. Spin-drying: After the waste liquid is discharged, keep the drive motor running so that the collection tank spins dry the adsorbed residual mother liquid during rapid rotation.

[0021] S7. Unloading: Open the top cover and remove the storage bucket along with the saturated resin particles from inside the main frame for further processing.

[0022] The present invention provides an aspartame production mother liquor recovery and treatment device and process, which has the following advantages: by setting an auxiliary structure, a socket for inserting a storage bucket is opened at the top of the rotating disk, and the positioning block is pressed by the elastic force of the return spring and slides along the direction of the storage bucket in the sliding groove through the slider and is locked into the inside of the positioning groove to form an embedding, thereby making the storage bucket stably installed. When the storage bucket is removed, it is only necessary to reverse the pusher to make the positioning block exit from the positioning groove and pull the storage bucket upward, thereby improving the recovery efficiency of the device.

[0023] By setting a stable structure, a pressing plate is placed on top of the storage bucket, and the top of the storage bucket is inserted into the groove. Then the top cover is installed on the top of the main frame. During this process, the insert block is pushed upward by the spring force of the pressing spring, and the pushing docking plate is inserted into the groove. This makes the rotation of the storage bucket more stable, so that the resin particles will not break due to excessive collision when adsorbing aspartame mother liquor, thus improving the stability of the device.

[0024] By incorporating a cleaning structure, an installation groove is created at the bottom of the rotating disk, allowing the support plate to snap into the groove. The support plate remains stable under the double engagement of the snap-fit ​​spring and the locking block. As the rotating disk continues to rotate, the scraper will scrape away the dirt at the bottom of the main frame, thus preventing dirt residue from remaining inside the device and achieving the removal of residue from the bottom.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Please see Figures 1-11 This invention provides an aspartame production mother liquor recovery and treatment device and process, including a main frame 1 and a top cover 4. Diversion pipes 2 are installed on both sides of the main frame 1, nozzles 3 are installed on both sides of the inner wall of the main frame 1, and the top cover 4 is installed at the top of the main frame 1. A collection tank 6 is installed inside the main frame 1, and a drain port 7 is provided at the bottom of one side of the main frame 1. A rotating disk 8 is rotatably connected to the bottom of the inside of the main frame 1, and a drive motor 10 is installed at the bottom of the main frame 1. A material rack 12 is installed inside the collection tank 6, and an auxiliary structure 9 is fixedly connected to the top of the rotating disk 8. The auxiliary structure 9 includes a positioning groove 901, a socket 902, a slide 903, a return spring 904, a positioning block 905, an anti-slip groove 906, a slider 907, and a lever 908. The positioning groove 901 is located at the bottom of the outer wall of the storage bucket 6. The top of the rotating disk 8 is fixedly connected to the socket 902. The inner side wall of the socket 902 is provided with a sliding groove 903. A return spring 904 is fixedly connected to one side of the sliding groove 903. A positioning block 905 is fixedly connected to one side of the return spring 904. An anti-slip groove 906 is provided on one side of the positioning block 905. A slider 907 is fixedly connected to one side of both ends of the positioning block 905. A paddle 908 is fixedly connected to one side of the top of the positioning block 905. The positioning groove 901 and the positioning block 905 are in an embedded structure. The socket 902 is distributed in a ring at the top of the rotating disk 8. The positioning block 905 is in a sliding structure inside the sliding groove 903 through the slider 907. The anti-slip groove 906 is distributed at equal intervals on one side of the positioning block 905.

[0039] See attached document Figure 1 , Figure 2 , Figure 6 , Figure 7 and Figure 8When the recycling device is in use, resin particles that can adsorb the corresponding components in the aspartame mother liquor are sequentially placed into the placement trays of the carrier rack 12, and the carrier rack 12 containing the resin particles is inserted into the storage tank 6. Then, several storage tanks 6 are installed on the top of the rotating disk 8 and the top cover 4 is closed. The aspartame mother liquor is sprayed from the nozzle 3 towards the storage tank 6 through the diversion pipe 2 on one side. At the same time, the drive motor 10 is started to drive the rotating disk 8 to rotate at a uniform speed. The rotating nozzle 3 sprays aspartame mother liquor evenly onto the resin inside each container 6, causing the resin to quickly absorb the corresponding substances in the aspartame mother liquor. Once a certain volume of aspartame mother liquor has been injected, the injection stops, allowing the rotating container 6 to continue absorbing the corresponding substances. As time passes and the resin becomes saturated, the drain port 7 is opened to discharge the waste liquid, and the top cover 4 is opened to remove the material carrier 12 from inside the container 6. The saturated resin particles are removed to recover the corresponding substances in the aspartame mother liquor. To facilitate the recovery and removal of the resin particles, a socket 902 is provided at the top of the rotating disk 8 for the storage bucket 6 to be inserted. Under the elastic pressure of the return spring 904, the positioning block 905 slides along the inside of the slide groove 903 towards the storage bucket 6 and is inserted into the positioning groove 901 to form an embedded structure. This ensures the stable installation of the storage bucket 6 and allows it to rotate at a uniform speed under the drive of the rotating disk 8. When removing the storage bucket 6, simply reverse the lever 908 to remove the positioning block 905 from the positioning groove 901 and pull the storage bucket 6 upwards. After the substances in the aspartame mother liquor are completely adsorbed by the resin and the waste liquid is discharged from the drain port 7, the continuous rotation of the rotating disk 8 can cause the residual waste liquid in the storage bucket 6 to be thrown out and accelerate the drying of the saturated resin, making subsequent resin processing more convenient.

[0040] The bottom of the top cover 4 is provided with a stabilizing structure 5, which includes a pressing plate 501, an inlay groove 502, a roller 503, a limiting seat 504, a guide groove 505, an inlay block 506, a docking plate 507, a docking groove 508, a guide block 509, and a pressing spring 510. The pressing plate 501 is installed on the top of the storage bucket 6. The inlay groove 502 is opened inside the bottom of the pressing plate 501. The roller 503 is rotatably connected to the inside of the outer wall of the pressing plate 501. The limiting seat 504 is fixedly connected to the top of the pressing plate 501. The guide groove 505 is opened inside the outer wall of the limiting seat 504. The limiting seat 504 has an inlay block 506 slidably connected inside. The top of the inlay block 506 is rotatably connected to the docking plate 507. The bottom of the top cover 4 has a docking groove 508. The bottom of the outer wall of the inlay block 506 is fixedly connected to the guide block 509. The bottom of the inlay block 506 is fixedly connected to the pressing spring 510. The inlay groove 502 is distributed in a ring inside the bottom of the pressing plate 501. The inlay groove 502 and the top of the outer wall of the storage bucket 6 are inlaid. The guide groove 505 and the guide block 509 are in a sliding structure. The docking plate 507 and the docking groove 508 are inlaid.

[0041] See attached document Figure 1 , Figure 3 , Figure 4 and Figure 5 When the recycling device is in use, in order to make the rotation of the collection bucket 6 more stable, after the collection bucket 6 is stably installed, the pressing plate 501 is placed on top of it, and the top of the collection bucket 6 is inserted into the inside of the insert groove 502. Then, the top cover 4 is installed on the top of the main frame 1. During this process, the insert block 506 is pushed upward by the elastic force of the pressing spring 510, and the sliding structure of the guide groove 505 and the guide block 509 pushes the docking plate 507 into the inside of the docking groove 508, so as to keep the pressing plate 501 stable. When the collection bucket 6 is driven by the rotating disk 8 to rotate, the pressing plate 501 will also rotate together under the rolling of the roller 503, so as to make the rotation of the collection bucket 6 more stable, and thus prevent the resin particles from breaking due to excessive collision when adsorbing the aspartame mother liquor.

[0042] A cleaning structure 11 is provided at the bottom of the rotating disk 8. The cleaning structure 11 includes a mounting groove 1101, a slot 1102, a support plate 1103, a scraper 1104, a snap-fit ​​spring 1105, and a snap-fit ​​block 1106.

The slot 1102 and the snap-fit ​​spring 1105 are in an engaging structure.

[0043] See attached document Figure 1 , Figure 9 , Figure 10 and Figure 11 When the resin particles inside the storage tank 6 are saturated with the aspartame mother liquor, the drain port 7 is opened to discharge the waste liquid. To prevent particulate impurities or accumulated liquid in the mother liquor from forming hard-to-clean stains at the bottom of the main frame 1, an installation groove 1101 is opened at the bottom of the rotating disk 8, and the support plate 1103 can be inserted into the installation groove 1101. The support plate 1103 is kept stable by the double engagement of the snap-fit ​​spring 1105 and the snap-fit ​​block 1106. When the rotating disk 8 continues to rotate, the scraper 1104 will scrape off the dirt at the bottom of the main frame 1, thereby preventing dirt residue from appearing in the device.
