More specifically, the present application provides a solution for a continuous degassing device, in particular a normal pressure continuous degassing device. Background Art
[0002] In the production process of condensed matter physics, new nanomaterials, semiconductors, chemicals, medicines, coatings and adhesives, it is often necessary to quickly degas the raw materials. For this reason, people have conducted a lot of research.
[0003] For example, Chinese patent application CN202876445U discloses a continuous vacuum degassing machine; in this scheme, the cylinder and the cylinder cover form a sealed cavity, the outer diameter of the drum is smaller than the inner diameter of the cylinder, the drum can rotate at high speed in the cylinder, the cavity is evacuated to negative pressure through the vacuum interface, the slurry is sucked into the drum from the feed pipe, the drum rotates at high speed, the slurry forms a film on the inner wall of the drum, tiny bubbles are separated from the slurry, the bubbles are extracted with the vacuum pump, and the slurry overflows from the discharge pipe under the action of centrifugal force, thereby achieving the purpose of continuous degassing of the slurry.
[0004] Chinese patent application CN206424637U discloses a continuous vacuum degassing degasser, whose working process is as follows: first, vacuum treatment is carried out. When the vacuum degree reaches the requirement, the frequency conversion motor drives the drum at the end of the shaft to rotate through the shaft; then, the paint to be degassed is fed into the drum through the feed port; under the action of the centrifugal force generated by the high-speed rotation of the drum, the paint hits the inner wall of the outer cylinder through the slender gaps around the drum. In this process, the bubbles in the paint are separated from the liquid and burst under the negative pressure environment, and the slender gaps around the drum and the impact also play an auxiliary role in defoaming.
[0005] Chinese patent application CN107774016A discloses an online vacuum degassing device, whose working process is as follows: the material enters through the feed port and is transported to the dispersion disk by the guide pipe. The rotation of the motor drives the dispersion disk to rotate at a high speed, generating a large centrifugal force, so that the material is thrown out from the dispersion disk and hits the inner barrel wall. A thin film is formed at the moment the material is thrown out. With the help of the vacuum negative pressure generated by the vacuum port, the bubbles are broken and degassed, and finally the material flows down along the inner barrel wall to the bottom of the tank.
[0006] Chinese patent application CN110917663A discloses a continuous degassing device and method for solvent-spinning cellulose spinning solution, which includes a rotating umbrella-shaped body and a double-conical spiral ribbon; the function of the rotating umbrella-shaped body is to allow the spinning solution to flow down from the inner surface; when in working state, the rotation speed of the rotating umbrella-shaped body is higher than the rotation speed of the double-conical spiral ribbon. The device uses centrifugal separation degassing, gravity degassing, stirring and scraping film degassing under vacuum conditions to perform multi-stage forced film formation and mechanical bubble crushing on the spinning solution.
[0007] Chinese patent application CN112807753A discloses a continuous degassing machine with a vacuum rotating distribution and discharge disk. The working process of the device is as follows: first, the separation tank is evacuated through a vacuum tube, and the slurry to be processed is injected through the feed pipe. The slurry falls into the corresponding distribution and discharge disks through the feed pipes. The motor drives the distribution and discharge disk to rotate. The slurry separates from the distribution and discharge disk under the action of centrifugal force inside the distribution and discharge disk, and is sprayed onto the inner wall of the discharge barrel corresponding to the distribution and discharge disk. Under the action of gravity, the slurry slides downward along the inner wall of the discharge barrel to form a film state. In the vacuum environment, the bubbles in the slurry overflow and burst, thereby achieving a degassing effect.
[0008] Chinese patent application CN214512879U discloses a vacuum single scraper continuous degassing machine, the working process of which is as follows: first, the separation tank is evacuated through a vacuum tube, and the slurry to be processed is injected through a feed pipe. The motor drives the umbrella-shaped batching disk to rotate, and the slurry passes through the feed pipe to the umbrella-shaped batching disk. Under the action of centrifugal force, the slurry flows from the center to the edge, and continues to be scraped to the edge of the umbrella-shaped batching disk after encountering the slurry scraper. Then the slurry is thrown to the inner wall of the separation tank. Under the action of gravity, the slurry slides down along the inner wall of the discharge barrel to form a film state. In a vacuum environment, the bubbles in the slurry overflow and burst to achieve a degassing effect. By setting a slurry scraper, the slurry is first degassed in a film on the umbrella-shaped dispersion disk, thereby increasing the film time and enhancing the degassing effect. It is particularly suitable for degassing slurries with large surface tension.
[0009] Chinese patent application CN113750576A discloses a centrifugal vacuum degassing device for online continuous processing, and Chinese patent application CN215462218U discloses a centrifugal degassing disk for continuous processing. The working processes of the above two are as follows: after the slurry enters the crushing and membrane chamber, under the action of centrifugal force, the slurry is blocked and guided by the crushing baffle ring in the crushing and membrane chamber, the slurry is broken and membraned, large bubbles are initially separated, and enter the centrifugal separation chamber more evenly, which can prevent the slurry containing more bubbles from directly passing through the subsequent cavity at high speed under the action of inertia; the slurry comes to the centrifugal separation chamber, and under the blocking of the upper baffle and the circular belly plate, a higher centrifugal force is formed, and the bubbles in the slurry are centrifugally separated. With the addition of materials, the slurry after the bubbles are centrifugally separated continuously enters the membrane chamber through the channel hole, and then the slurry flows into the material throwing chamber through the discharge hole and the inner edge of the annular pressure baffle, and then under the action of centrifugal force, it is ejected and thrown out from the throwing hole in the state of small particles to further separate the bubbles.
[0010] Chinese patent application CN210933907U discloses a fast continuous vibration degassing device for supporting high-viscosity colloids. A vibration motor is provided on the vibration table of the device, which achieves the purpose of degassing through high-frequency vibration.
