Description

Technical Field

[0001] This utility model belongs to the technical field of organic chemical synthesis equipment, specifically relating to a multi-partition vacuum buffer tank for the production of alkyl glycosides. Background Technology

[0002] In the production of alkyl glycosides, the multi-partition vacuum buffer tank is a key piece of equipment, mainly used for vacuum stabilization control and material buffering of the reaction system. In the APG synthesis stage, the vacuum environment helps to remove by-products (such as lower alcohols) and promote reaction equilibrium. The multi-partition design can effectively separate the gas and liquid phases, prevent material entrainment and foam formation, and reduce vacuum system fluctuations through staged buffering.

[0003] Currently, in the production process of alkyl glycosides (APG), the right-angled structure of the partition edges of the multi-partition vacuum buffer tank can easily lead to material residue problems. Because the APG solution has a certain viscosity and surface activity, it is easy to form a stagnant liquid film on the edge of the partition in a vacuum environment. These residual liquid films are difficult to completely remove through conventional discharge. After long-term accumulation, they may cause microbial growth, cross-contamination, or affect the purity of the product. Utility Model Content

[0030] Example

[0031] Reference Figures 1-6 This embodiment of the present invention provides a multi-partition vacuum buffer tank for the production of alkyl glycosides, comprising:

[0032] The support mechanism 100 includes a tank 110 and a limiting ring 120 fixedly installed in the inner cavity of the tank 110;

[0033] The isolation mechanism 200 includes a shaft 210 vertically installed in the inner cavity of the tank 110, a horizontal partition 220 movably locked in the inner cavity of the limit ring 120, a cleaning assembly 230 disposed outside the horizontal partition 220, and a support assembly 240 disposed at the bottom of the cleaning assembly 230.

[0034] The design of the bearing mechanism 100 and the isolation mechanism 200 enables the stable installation and dynamic cleaning of the multi-stage baffles in the tank 110. The limit ring 120 ensures the precise positioning of the horizontal baffle 220. The combination of the shaft 210 and the cleaning component 230 can effectively solve the problem of liquid film residue at the edge of the baffle, improve the separation efficiency of alkyl glycoside production and reduce the risk of cross-contamination.

[0035] Specifically, the cleaning component 230 includes a horizontal plate 231 movably mounted on the top of the horizontal partition 220, a vertical rod 232 movably sleeved in the inner cavity of the horizontal plate 231, and a limiting block 233 fixedly installed on the top of the vertical rod 232. The cleaning component 230 also includes a limiting ring 234 movably sleeved on the outside of the vertical rod 232, an arc-shaped scraper 235 fixedly installed at the bottom of the horizontal plate 231, a return spring 236 fixedly installed on the top of the limiting ring 234, and a circular plate 237 fixedly installed at the bottom of the vertical rod 232. There are three sets of horizontal partitions 220, which are vertically and evenly distributed from top to bottom in the inner cavity of the tank 110.

[0036] The cleaning component 230 employs a sliding structure of horizontal plate 231 and vertical rod 232, coupled with the constraint of limiting block 233, to mechanically scrape away residues on the surface of horizontal partition 220. This avoids the problem of incomplete cleaning caused by material adhesion in traditional fixed scrapers, making it particularly suitable for high-viscosity alkyl glycoside solutions. Through the elastic reset mechanism of limiting ring 234 and reset spring 236, the arc-shaped scraper 235 can adaptively conform to the arc edge of horizontal partition 220, maintaining stable scraping force even with slight deformation or installation errors. Circular plate 237 further limits the displacement range of vertical rod 232, preventing excessive compression of the spring and extending the service life of cleaning component 230. The uniform distribution of three sets of horizontal partitions 220 forms a stepped buffer separation space, extending material residence time and enhancing gas-liquid separation. The multi-stage structure can intercept foam or droplets of different particle sizes in stages, making it particularly suitable for conditions where foam is easily generated during alkyl glycoside synthesis.

[0037] Furthermore, the support assembly 240 also includes a support plate 241 fixedly installed on the outside of the limiting ring 234, a through hole 242 opened on one side of the support plate 241, and a scraper 243 fixedly installed on the top of the support plate 241.

[0038] The synergistic effect of the support plate 241 and the scraper 243 can remove crystals or deposits in the dead corners of the edge of the horizontal partition 220. The through hole 242 provides a guide channel for the vertical rod 232, ensuring the straightness of the cleaning action, avoiding skewed wear, significantly improving the cleanliness of the edge of the partition, and reducing the risk of microbial growth.

[0039] Preferably, the isolation mechanism 200 also includes a guide channel 250 formed on the top of the horizontal partition 220, a connecting rod 260 fixedly installed on the outside of the shaft 210, a screw 270 threadedly installed on the top of the connecting rod 260, and a servo motor 280 fixedly installed on the top of the tank body 110. The screw 270 is threadedly connected to the top of the horizontal plate 231, the output end of the servo motor 280 is fixedly connected to the top of the shaft 210, and the vertical rod 232 is movably sleeved in the inner cavity of the through hole 242.

[0040] The guide channel 250 and the connecting rod 260 work together to enable the cleaning component 230 to move along a preset path, avoiding disorderly scraping. The servo motor 280 drives the entire cleaning system through the shaft 210 to achieve automated control. The screw 270 provides an adjustable connection method, which is convenient for maintenance or replacement of parts. The servo motor 280 directly drives the shaft 210 to rotate, which is efficient in power transmission and has a rapid response. The sliding fit between the vertical rod 232 and the through hole 242 further ensures the stability of the cleaning action and avoids deviation caused by vibration, which is suitable for long-term continuous operation.

[0041] Furthermore, the bearing mechanism 100 also includes a gas-liquid separator 130 fixedly installed in the inner cavity of the tank 110, a vacuum tube 140 fixedly installed on one side of the tank 110, and a discharge pipe 150 fixedly installed on the other side of the tank 110.

[0042] Among them, the gas-liquid separator 130 is integrated into the tank 110, which can efficiently intercept entrained droplets and improve the stability of the vacuum system. The symmetrical layout of the vacuum tube 140 and the discharge tube 150 optimizes the fluid distribution, reduces eddies or dead zones, ensures thorough material discharge, and reduces the risk of residue.

[0043] During use, the material enters the tank 110 through the feed inlet and flows through three horizontal baffles 220 in stages under the negative pressure environment formed by the vacuum tube 140. Gas-liquid separation is achieved through stepped buffering. The servo motor 280 drives the shaft 210 to rotate, which drives the connecting rod 260 to make the cleaning component 230 move along the guide channel 250. At this time, the reset spring 236 pushes the arc-shaped scraper 235 to scrape back and forth against the edge of the baffle. At the same time, the scraper 243 on the support plate 241 removes dead corner residue. The separated gas phase is discharged after being defoamed by the gas-liquid separator 130, and the liquid phase is completely discharged through the discharge pipe 150 with optimized flow channel. The whole process realizes the coordinated operation of dynamic cleaning and continuous production.

[0044] In summary, through the coordinated design of the supporting mechanism 100 and the isolation mechanism 200, efficient gas-liquid separation and automated cleaning functions are achieved in the alkyl glycoside production process. The three sets of horizontal baffles 220 form a stepped buffer space, which significantly extends the material residence time and intercepts foam in stages.

[0045] The cleaning component 230, through the adaptive design of the elastic reset mechanism and the arc-shaped scraper 235, combined with the shaft 210 system driven by the servo motor 280, can thoroughly remove the sticky residue on the edge of the partition and prevent the growth of microorganisms.

[0046] The support component 240 and the guide channel 250 further ensure the precision and stability of the cleaning action, while the integrated gas-liquid separator 130 and the symmetrically arranged vacuum tube 140 and discharge 150 optimize the fluid distribution. The overall structure improves the separation efficiency and effectively solves the problems of high residue rate and difficult maintenance of traditional equipment. It is especially suitable for the production process of high viscosity and easy foaming alkyl glycosides.
