Description

Technical Field

[0001] The utility model relates to a vacuum feeding device for a reaction kettle used in the chemical industry. Background Art

[0002] The existing reactor device requires the powder to be manually added into the reactor by opening the feeding port on the top of the reactor, which poses a safety hazard of powder flying. Although the vacuum suction device or structure in the prior art can vacuum-absorb the powder and avoid manual operation, the powder will still fly in the reactor after being sucked into the reactor and adhere to the wall of the reactor, so that the material cannot be completely dissolved into all the materials. At the same time, for liquid materials, the liquid splashed after filling is also easy to hang on the wall of the reactor, making it difficult for some materials to participate in the reaction. In addition, for processes that require extremely precise control of reaction materials, the materials remaining on the wall of the reactor will affect the accuracy of the material dosage, and thus affect the overall quality of the process. In the prior art, the feeding tube is deeply inserted below the liquid surface to prevent the flying and splashing of solids and liquids. However, for corrosive liquids, it is difficult to keep the feeding tube immersed below the liquid surface for a long time. Utility Model Content

[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and to provide a vacuum feeding device for a reactor, which can realize vacuum feeding of the reactor and prevent materials from hanging on the wall.

[0004] A technical solution for achieving the above object is: a vacuum feeding device for a reactor, comprising a vacuum pump and a feeding device connected to the reactor;

[0005] The top cover of the reactor is provided with a feeding port and a vacuum port. The vacuum port is connected to the vacuum pump through a vacuum pipe. The feeding port includes a liquid material port and a powder material port. The liquid material port is connected to the liquid material barrel through a liquid material pipe, and the powder material port is connected to the powder material box through a powder material pipe. The inner side of the top cover of the reactor is a funnel-shaped structure. The stirring shaft of the reactor extends into the interior of the reactor through the funnel mouth. A fitting gap is reserved between the funnel mouth and the stirring shaft. The liquid material port and the powder material port are respectively arranged opposite the edges of the funnel structure.

[0006] Furthermore, a wall scraping device is connected to the stirring shaft, and the wall scraping device faces the side wall of the funnel-shaped structure.

[0007] Furthermore, several groups of scraping devices are arranged on the stirring shaft from top to bottom.

[0008] Furthermore, the vacuum pipe is provided with a vacuum valve, and the liquid material pipe and the powder material pipe are provided with a feeding valve.

[0009] Furthermore, the powder material pipe is a plastic hose, and the liquid material pipe and the vacuum pipe are metal pipes.

[0010] The utility model discloses a vacuum feeding device for a reactor. A vacuum pump is used to evacuate the reactor, and then powder is directly drawn from the powder box through a powder pipe for feeding. This avoids manual operation that causes powder to fly, and improves production efficiency. The funnel-shaped structure of the top cover allows both powder and liquid to move along the funnel to the center of the reactor, and then fall down for feeding, minimizing the amount of material hanging on the reactor wall. The scraping device can collect and drop material on the surface of the funnel-shaped structure toward the center, further allowing the material to fully enter the reactor for reaction. This utility model improves feeding efficiency and makes material control of the process more precise, thereby improving the overall accuracy and quality of the process. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 This is a structural schematic diagram of a device (equipment, system, structure) of a vacuum feeding device for a reactor of the present invention. DETAILED DESCRIPTION

[0012] In order to better understand the technical solution of the present invention, the following is a detailed description through specific embodiments:

[0013] See also Figure 1 The utility model relates to a vacuum feeding device for a reactor. The top cover 1 of the reactor is provided with a feeding port and a vacuum port 3. The feeding port includes a liquid material port 21 and a powder material port 22.

[0014] The vacuum port 3 is connected to a vacuum pump via a vacuum pipe, and the vacuum pipe is provided with a vacuum valve.

[0015] Preferably, the vacuum tube is a metal tube rigidly connected to the top cover and equipped with a vacuum valve. A vacuum pump is mounted on one side of the top cover. When the vacuum pump is running, its slight vibration is transmitted through the vacuum tube to the top cover, causing the top cover to vibrate. This allows the powder to fall more easily along the internal structure of the top cover during loading, preventing it from clinging to the wall.

[0016] The liquid inlet 21 is connected to the liquid tank via a liquid pipe, while the powder inlet 22 is connected to the powder tank via a powder pipe. The liquid pipe is a metal pipe. The powder pipe is a flexible plastic tube that is fully movable to adjust the angle of powder absorption. Both the liquid pipe and the powder pipe are equipped with loading valves.

[0017] The reactor's top cover 1 has a funnel-shaped structure on the inside, with a liquid feed port 21 and a powder feed port 22 positioned directly opposite the edges of the funnel. During loading, the material flows along the sidewalls of the funnel toward the central funnel opening, concentrating its entry into the reactor in the center and minimizing scraping of the reactor's sidewalls. The reactor's agitator shaft 4 extends through the funnel opening into the reactor, with a clearance between the funnel opening and the agitator shaft reserved for material passage.

[0018] Furthermore, a scraper 41 is connected to the agitator shaft 4, facing the sidewalls of the funnel-shaped structure. The scraper 41 can be a linear scraper or a spiral scraper, used to scrape material from the sidewalls of the funnel-shaped structure and further collect it toward the center. In this embodiment, the agitator shaft is equipped with a single set of scrapers. In other embodiments, the agitator shaft can be equipped with multiple sets of scrapers of varying lengths from top to bottom.

[0019] Those skilled in the art should recognize that the above embodiments are merely intended to illustrate the present invention and are not intended to limit the present invention. As long as they are within the spirit of the present invention, any changes or modifications to the above embodiments will fall within the scope of the claims of the present invention.
