Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of continuous spinning production, and in particular relates to a continuous spinning slurry mixing circulation system. Background Art
[0002] At present, our company has a sizing process in the continuous spinning production process. The raw pulp used for sizing is mainly a mixture of pulp and oil. If the above two organic substances are not mixed evenly or the impurities are not filtered cleanly, it will cause uneven sizing rate of the silk strips and affect product quality.
[0003] like Figure 3 As shown, the current slurry preparation system: first add a certain volume of desalted water into the batching tank, start stirring, and heat up to 35-40°C; then pour a certain amount of powdered material into the batching tank at one time, stir and heat to 70-85°C, and start the circulation pump for internal circulation. When the temperature drops to 50-60°C, add oil and stir evenly; when the temperature drops to 25-35°C, add bactericide, and then transfer directly to the storage tank for use in the machine.
[0004] The current problems are as follows: 1. The feed port is a cylindrical barrel structure. When the powder slurry is poured in, it cannot be added evenly, which usually causes the material to be sometimes large and sometimes small. After the material is dissolved in water, it cannot be evenly dispersed. 2. There is no filtration system, and it is impossible to filter out impurities in the mixed material and newly generated solid impurities. 3. The material is stored in the pipeline for a long time and cannot be circulated, so the material in the pipeline is stored for a long time and the uniformity becomes poor. Utility Model Content

Oil is added, fully mixed, and the temperature is reduced for the second time. A bactericide is added, and the slurry is mixed; the slurry is switched into the transfer discharge tank, and the second stirring mechanism is started at the same time to ensure that the slurry is always in a uniformly mixed state, and the slurry is prevented from settling and stratifying, which affects the uniformity of the components; the second circulation pump or the third circulation pump is started, and the slurry is sent to the second filter for secondary filtration, and then the slurry is sent to the spinning machine for use on the one hand, and the slurry is sent back to the transfer storage tank through the second reflux pipe on the other hand, and is always in a flowing state.
