Description

Technical Field

[0001] This utility model relates to a purification device, and more particularly to a purification device for sodium cocoyl glycinate. Background Technology

[0002] In the processing of sodium cocoyl glycinate powder, purification of sodium cocoyl glycinate is required through a sedimentation tank. Specifically, a sodium cocoyl glycinate salt solution containing impurities is fed into the sedimentation tank, and a corresponding precipitant is added to acidify the solution, causing the sodium cocoyl glycinate to precipitate and form loose, flocculent aggregates. These flocculent aggregates settle at the bottom of the sedimentation tank after settling, and then the solution and aggregates are discharged in batches from the sedimentation tank, thus achieving the purification function of sodium cocoyl glycinate.

[0003] However, the above process encounters a problem in actual operation: because the aggregates of sodium cocoyl glycinate after precipitation are highly viscous pastes, these pastes adhere to the inner wall of the sedimentation tank after the solution is discharged, preventing them from sliding outwards along the conical groove at the bottom of the tank. While some sedimentation tanks can currently remove the adhering material from the bottom using scrapers, these scrapers are directly mounted on the stirring shaft and rotate synchronously with it during processing. This leads to frictional wear during continuous rotation, reducing the scraper's lifespan and requiring frequent replacements. Furthermore, the scrapers, in conjunction with the groove, can shear the aggregates during stirring, causing them to break down into small particles that are discharged with the solution, thus reducing the sedimentation tank's separation efficiency between the solution and the aggregates.

[0004] Therefore, existing purification devices for sodium cocoyl glycinate suffer from problems such as short scraper life and poor stability of aggregate emissions. Utility Model Content

[0005] The purpose of this invention is to provide a purification device for sodium cocoyl glycinate. It can improve the service life of the scraper and enhance the stability of aggregate discharge.

[0006] The technical solution of this utility model: a purification device for sodium cocoyl glycinate, including a tank body, an inlet at the top of the tank body, an outlet pipe at the bottom of the tank body, a drain pipe connected to one side of the outlet pipe, a conical groove formed on the side wall of the tank body above the outlet pipe, and a stirring tube rotatably connected to the middle of the tank body. The upper end of the stirring tube extends to the outside of the tank body and is connected to a drive motor. A lifting shaft is slidably connected to the inner side of the stirring tube. The upper end of the lifting shaft extends to the outside of the stirring tube and is connected to a lifting component. The lifting shaft and the stirring tube are connected to each other through a transmission mechanism. The lower end of the lifting shaft extends to the outside of the stirring tube and is connected to a support shaft. Several scrapers with matching grooves are distributed around the support shaft.

[0007] In the aforementioned purification device for sodium cocoyl glycinate, the support shaft and the lifting shaft are bolted together via connecting flanges.

[0008] In the aforementioned purification device for sodium cocoyl glycinate, an annular groove is formed at the upper end of the lifting shaft, and a lifting plate is fastened to the outside of the annular groove. The outer end of the lifting plate is connected to a lifting component.

[0009] In the aforementioned purification device for sodium cocoyl glycinate, the transmission mechanism includes a first transmission component. The upper end of the lifting shaft extends to the outside of the stirring tube and is connected to the first transmission component. A support plate is fixedly connected to the outside of the stirring tube below the first transmission component. A second transmission component is provided between the support plate and the first transmission component. The stirring tube is connected to the inner side of the second transmission component. A compression spring is connected between the second transmission component and the support plate. A transmission connection is formed between the second transmission component and the first transmission component.

[0010] In the aforementioned purification device for sodium cocoyl glycinate, the bottom of the first transmission component has multiple locking blocks arranged in a ring around its perimeter, and the top of the second transmission component has locking grooves that mate with the locking blocks arranged in a ring.

[0011] In the aforementioned purification device for sodium cocoyl glycinate, the second transmission component is sleeved on the outside of the stirring tube and forms a sliding connection with the stirring tube. A connecting key for transmission is provided between the second transmission component and the stirring tube.

[0012] In the aforementioned purification apparatus for sodium cocoyl glycinate, a gap is formed between the stirring tube and the first transmission component to allow the first transmission component to move axially, and the end of the second transmission component extends above the stirring tube and connects to the first transmission component.

[0013] Compared with the prior art, this utility model has the following characteristics: (1) The present invention uses the connection structure of the stirring tube, the lifting shaft and the support shaft to make the scraper rotate synchronously with the stirring tube and be separated from the trough during the rotation process. This allows the scraper to perform the stirring function while avoiding cutting the polymer deposited at the bottom of the tank, thus improving the discharge stability of the polymer. When it is necessary to scrape off the polymer deposited on the surface of the trough, the lifting component drives the lifting shaft to move vertically downward, so that the scraper moves and contacts the trough, thereby achieving the scraping function on the surface of the trough and preventing the polymer from adhering during the stirring and discharge process. (2) With the above combination, the scraper of this utility model does not need to form continuous friction with the chute during the stirring process, but can scrape the polymer on the surface of the chute at a specific frequency according to the manufacturer's requirements, effectively extending the service life of the scraper. (3) By limiting the structure of the transmission mechanism, on the one hand, it can achieve stable drive rotation of the lifting shaft when the lifting shaft is raised and lowered, and on the other hand, it can separate the first transmission component and the second transmission component by raising the lifting shaft in special circumstances, that is, control the scraper to stop rotating, thereby effectively improving the manufacturer's control flexibility of the scraper action. Therefore, this invention can improve the service life of the scraper and enhance the stability of aggregate emission. Attached Figure Description

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0017] Example. A purification apparatus for sodium cocoyl glycinate is configured as follows: Figure 1As shown, the tank includes a tank body 1, a feed inlet 2 at the top of the tank body 1, a discharge pipe 3 at the bottom of the tank body 1, a valve installed at the bottom of the discharge pipe 3, a drain pipe 4 connected to one side of the discharge pipe 3, a filter screen for filtering the polymer at the inner end of the drain pipe 4, and a conical groove 5 formed on the side wall of the tank body 1 above the discharge pipe 3. It also includes a stirring tube 6 rotatably connected to the middle of the tank body 1. Several stirring blades are distributed in a ring around the middle of the stirring tube 6. The top of the stirring tube 6 is rotatably connected to the tank body 1 via a bearing. The upper end of the stirring tube 6 extends to the outside of the tank body 1 and is connected to a drive motor 7 via a chain drive mechanism. A lifting shaft 8 is slidably connected to the inside of the stirring tube 6. The upper end of the lifting shaft 8 extends to the outside of the stirring tube 6 and is connected to a lifting component 9. The lifting shaft 8 and the stirring tube 6 are connected to each other via a transmission mechanism. The lower end of the lifting shaft 8 extends to the outside of the stirring tube 6 and is connected to a support shaft 10. Several scrapers 11 with matching sliding grooves 5 are distributed around the support shaft 10.

[0018] The scraper 11 is made of polytetrafluoroethylene or polyurethane.

[0019] The support shaft 10 and the lifting shaft 8 are bolted together via a connecting flange.

[0020] The upper end of the lifting shaft 8 forms an annular groove 12, and a lifting plate 13 is fastened to the outside of the annular groove 12. The lifting plate 13 is made of nylon and the height of the annular groove 12 is greater than the thickness of the lifting plate 13, so that the lifting shaft 8 can continuously rotate inside the lifting plate 13 during use. The outer end of the lifting plate 13 is connected to a lifting component 9, which can be an electric push rod. The electric push rod is fixedly connected to the top of the tank body 1.

[0021] The transmission mechanism includes a first transmission component 14. The upper end of the lifting shaft 8 extends to the outside of the stirring tube 6 and is fixedly connected to the first transmission component 14. Below the first transmission component 14, a support plate 15 is fixedly connected to the outside of the stirring tube 6. In actual installation, the manufacturer can use the sprocket of the chain drive mechanism as the support plate 15. The sprocket and the stirring tube 6 are welded firmly to each other. A second transmission component 16 is provided between the support plate 15 and the first transmission component 14. The inner side of the second transmission component 16 is connected to the stirring tube 6. A compression spring 17 is connected between the second transmission component 16 and the support plate 15. A transmission connection is formed between the second transmission component 16 and the first transmission component 14.

[0022] The bottom of the first transmission component 14 has a plurality of locking blocks 18 arranged in a ring around its perimeter, with adjacent locking blocks 18 being separated from each other. The top of the second transmission component 16 has locking grooves 19 arranged in a ring around its top to engage with the locking blocks 18.

[0023] The second transmission component 16 is sleeved on the outside of the stirring tube 6 and forms a sliding connection with the stirring tube 6. A connecting key for transmission is provided between the second transmission component 16 and the stirring tube 6.

[0024] A gap is formed between the stirring tube 6 and the first transmission member 14 to allow the first transmission member 14 to move axially. The end of the second transmission member 16 extends above the stirring tube 6 and connects to the first transmission member 14.

[0025] The working principle of this invention is as follows: During use, the stirring tube 6 is driven by the drive motor 7 to rotate and stir the solution inside the tank 1. Under normal operating conditions, the lifting shaft 8 is in the stirring position through the cooperation of the lifting component 9 and the lifting plate 13. This allows the stirring tube 6 to drive the lifting shaft 8 to rotate synchronously via the interlocking of the first transmission component 14 and the second transmission component 16, keeping the scraper 11 rotating and achieving the stirring function. In this state, the scraper 11 and the sliding groove 5 are separated, thus preventing frictional damage to the scraper 11.

[0026] After the lifting shaft 8 has rotated normally for a specified time, the lifting component 9 lowers the lifting shaft 8 to the scraping position, where the scraper 11 and the chute 5 are in contact. During the descent of the lifting shaft 8, the first transmission component 14 applies a downward squeezing force to the second transmission component 16, causing the second transmission component 16 to descend synchronously with the lifting shaft 8, while the first and second transmission components 14 remain engaged. After the scraper 11 has descended to its designated position, it is driven by the stirring tube 6 to maintain rotation, thereby scraping away the polymer adhering to the surface of the chute 5 and preventing the polymer from adhering firmly to the surface of the chute 5. After the scraper 11 has rotated for a specified time or number of revolutions, the lifting component 9 raises the lifting shaft 8 again, separating the scraper 11 from the chute 5 and returning it to the stirring state. With the above-mentioned cooperation, the manufacturer can use the scraper 11 to periodically scrape the surface of the chute 5, and at other times separate the scraper 11 from the chute 5 and use it as a stirring blade, thereby effectively avoiding wear caused by long-term contact between the scraper 11 and the chute 5; at the same time, it prevents polymer from depositing on the surface of the chute 5 and forming adhesion.

[0027] When it is necessary to stop the rotation of the scraper 11, the operator can also control the lifting shaft 8 to rise to the stop position, that is, the first transmission component 14 and the second transmission component 16 are separated from each other, thereby detaching the transmission connection between the stirring tube 6 and the lifting shaft 8, thereby improving the driving effect of the scraper 11.
