Technical Field

[0001] The utility model relates to the field of ingredients, and more specifically, it relates to a high-efficiency liquid dispensing tank for producing high-purity and stable polyvidone. Background Art

[0002] Povidone generally refers to polyvinyl pyrrolidone, referred to as PVP, which is a non-ionic polymer compound and the most distinctive, most deeply studied and most extensive fine chemical among N-vinyl amide polymers. It has developed into three major categories: non-ionic, cationic, and anionic, three specifications: industrial grade, pharmaceutical grade, and food grade, and a series of homopolymer, copolymer, and cross-linked polymer products with relative molecular weights ranging from thousands to more than one million, and has been widely used for its excellent and unique properties.

[0003] Povidone solution requires a mixing tank to complete the preparation and configuration. The mixing tank is a mixing and stirring container that mixes one or several materials according to the process ratio. Traditional mixing tanks can only mix raw materials, and workers are required to weigh the raw materials in advance and then add them. This manual quantitative addition method by workers is time-consuming and labor-intensive, which increases the work intensity and working hours of the staff, and indirectly reduces production efficiency.

[0004] Based on the above, the purpose of the utility model is to provide a high-efficiency liquid preparation tank for the production of high-purity and stable polyvidone, so as to solve the problem that traditional liquid preparation tanks require workers to manually perform quantitative addition, which is time-consuming and laborious. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model aims to provide an efficient liquid preparation tank for the production of high-purity and stable polyvidone. The utility model arranges a proportioning tank composed of a partition, a rotating ring and a cover plate on the tank body, the partition divides the proportioning tank into a plurality of storage chambers, and then arranges a lifting plate in the proportioning tank to control the storage amount of raw materials. The user can adjust the position of the lifting plate so that the amount of raw materials that can be stored in the plurality of storage chambers is respectively the amount required for the raw materials in the proportioning, and then arranges a movable plate 1 and a movable plate 2 that can move with the rotating ring, and the rotating ring drives the movable plate 1 and the movable plate 2 to alternately cover the feed trough and the feeding trough through rotation, so that the raw materials in the storage chamber flow into the tank body for mixing, so that the liquid preparation tank can automatically perform quantitative proportioning of the raw materials, thereby reducing the labor intensity of workers and increasing work efficiency.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions: a high-efficiency liquid dispensing tank for the production of high-purity and stable polyvidone, comprising a tank body, a discharge pipe and a stirring paddle are arranged on the tank body, a valve is arranged on the discharge pipe, a driving mechanism for driving the stirring paddle to rotate is arranged on the tank body, a proportioning tank is arranged on the tank body, the proportioning tank comprises a rotating ring rotatably connected to the tank body, a partition is arranged inside the rotating ring, one end of the partition is fixedly connected to the tank body, the other end of the partition is fixedly connected to a cover plate, the rotating ring is rotatably connected to the cover plate, the rotating ring is divided into more than two storage chambers by the partition, and the plurality of storage chambers are provided with a plurality of storage chambers. The lifting plates are all slidably connected, a feed pipe is fixedly connected to the lifting plates, the feed pipe is slidably connected to the cover plate, a feed hole communicated with the feed pipe is arranged on the lifting plates, a sliding groove is arranged in the lifting plates, a movable plate 1 is slidably connected in the sliding groove, a linkage mechanism for driving the movable plate 1 to move is arranged on the rotating ring, the movable plate 2 having the same number as the storage chamber is fixedly connected to the rotating ring, the position of the movable plate 2 corresponds to the movable plate 1 up and down, each storage chamber of the tank body is provided with a feeding trough, the feed pipe and the feeding trough are staggered, and a lifting mechanism for driving the lifting plates to lift and lower is arranged on the cover plate.

[0007] By adopting the above technical solution, when polyvidone needs to be prepared, the user connects multiple feeding tubes to storage devices of multiple raw materials outside respectively, so that each feeding tube and storage cavity corresponds to a required raw material, and then controls the height position of the lifting plates in the multiple storage cavities according to the lifting mechanism until the amount of raw materials that can be accommodated between the lifting plate and the top plate of the tank body is the required amount of this raw material, and then rotates the rotating ring. When the rotating ring rotates, it will drive the movable plate 2 to rotate, and will also drive the movable plate 1 to rotate through the linkage mechanism. During the movement of the movable plate 1, it will move away from the feeding hole, and during the movement of the movable plate 2, it will move closer to the feeding trough until the movable plate 2 moves. Plate 2 covers the feed trough. At this time, the feed hole loses the restriction of moving plate 1, and the raw materials will enter the storage chamber through the feed pipe and the feed hole until multiple storage chambers are filled with raw materials, and then the rotating ring is rotated in the opposite direction. The rotating ring will drive moving plate 1 and moving plate 2 to move in the opposite direction. In this process, moving plate 1 will block the feed hole to prevent the raw materials from continuing to flow into the storage chamber, and moving plate 2 will move away from the feed trough. The feed trough loses the cover of moving plate 2, and the raw materials in the storage chamber will flow into the tank body, and then the driving mechanism drives the stirring paddle to rotate, thereby mixing the raw materials. After the raw materials are mixed, the valve is opened to discharge the mixed raw materials from the discharge pipe.
