Description

Technical Field

[0001] This utility model relates to the field of chitosan production technology, specifically to a mixing device for chitosan processing. Background Technology

[0002] Chitosan is a natural polysaccharide that is widely used in food, pharmaceuticals, medicine, cosmetics, aquaculture and other fields due to its excellent biocompatibility and biodegradability. The production process of chitosan will be introduced below. The raw material of chitosan mainly comes from the shells of marine organisms.

[0003] During processing, the ground shell powder is often added with catalysts and other substances. Therefore, it is necessary to store multiple raw materials and control the amount of material fed to meet the appropriate mixing ratio. In addition, existing devices mostly add the components directly. When the materials enter the production equipment, they cannot make sufficient contact, resulting in unreliable product quality in subsequent production. To address this, we propose a mixing device for chitosan processing. Utility Model Content

[0004] The technical problem this invention aims to solve is to overcome existing defects and provide a mixing device for chitosan processing. This device features a reliable feeding control unit capable of controlling the separation and storage of various components and allowing for the addition of predetermined quantities. By opening the upper cover, materials in each cylinder can be replenished at any time. It also has a reliable mixing and stirring unit capable of thoroughly mixing the raw materials and catalysts used in chitosan production, ensuring uniform mixing before entering the production equipment. This facilitates subsequent production operations and guarantees better product quality. The hollow structure at the lower end of the columnar frame and the funnel together form a mixing chamber with a flexible sealing block, allowing for convenient control of the material in the mixing chamber as it enters the production equipment. This effectively solves the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mixing device for chitosan processing, comprising a columnar frame, a mixing and stirring unit, and a feeding control unit;

The bearing is located below the motor and is fixedly connected to the inner ring of the motor. The output shaft of the motor is fixedly connected to the upper end of the rotating shaft through a coupling. The lower end of the rotating shaft extends into the mixing chamber. Three mixing rods are fixedly connected in a circumferential array on the outer side of the rotating shaft. An electric push rod is embedded in the lower end of the rotating shaft. The telescopic end of the electric push rod extends downward and is fixedly connected to a circular sealing block at the end. The diameter of the sealing block is the same as that of the lower tube of the hopper.

[0009] The columnar frame is used for the installation of the storage cylinder and the feeding device. Its hollow structure at the lower end and the funnel together form a mixing chamber. The device is connected to the feed port of the chitosan processing equipment through the pipe at the lower end of the funnel. The material mixed in the mixing chamber is fed downward into the production equipment. The feeding control unit is used to control the quantitative addition of each component. In the mixing chamber, the motor drives the mixing rod through the rotating shaft to stir the various raw materials, so that the raw materials are fully mixed, which is convenient for subsequent processing. At the lower end of the rotating shaft, the electric push rod pushes the sealing block down into the pipe of the funnel to close the feeding pipe of the funnel.
