Description

TECHNICAL FIELD

[0001] The utility model belongs to the old drum equipment technical field, especially relate to a kind of external old drum temperature regulating water hinge system. BACKGROUND

[0002] In the production process of viscose fiber, the preparation of alkali cellulose is a crucial link. After crushing, alkali cellulose needs to be aged or aged under constant temperature conditions. This process is a meticulous and rigorous chemical reaction process, which has a decisive influence on the final performance of viscose fiber. The aging process is carried out in air, and cellulose reacts with oxygen, gradually oxidizing and degrading. In this process, the degree of polymerization of cellulose will gradually decrease until it reaches the required degree of process. This decreasing degree of polymerization is an essential step in viscose fiber production, which provides the necessary conditions for subsequent yellowing treatment. The purpose of aging is mainly to make alkali cellulose fully react with oxygen in the air. Through this reaction, the viscosity of alkali cellulose will gradually decrease to the range required by the process. This reduced viscosity alkali cellulose, after yellowing treatment, can produce viscose with qualified viscosity. This viscose has excellent filtering and spinnability, and is an indispensable raw material in viscose fiber production.

[0003] In the aging process, temperature is the main control parameter, and temperature directly affects the aging speed. When the aging temperature is high, the reaction between alkali cellulose and oxygen in the air accelerates. The higher the temperature, the faster the aging speed. The aging process must strictly control the temperature to make the prepared viscose uniform in viscosity. High-temperature aging is often used in the production of ordinary viscose staple fiber, and the internal material temperature is between 50℃ and 60℃ without cooling, while the material temperature required by the yellowing process is ≤30℃, so cooling is needed. At this time, a water temperature regulating system needs to be designed to regulate the temperature of the entire aging process.

[0004] The most widely used device on the market that can meet the process is an old drum, which slowly pushes the raw materials from the feeding end to the discharging end through the rotation of the drum body. The old process is continuous and automatic, and the production capacity is large. The main types of old drum temperature adjustment are air-cooled temperature adjustment and water-cooled temperature adjustment. However, since the total length of the drum body is basically between 20 meters and 35 meters, the cooling effect of air-cooled temperature adjustment is not very good, and the temperature of the raw materials in the drum body cannot be well controlled. And condensate water is easy to form at the air port and will drip into the drum body, affecting the product quality. The water-cooled temperature adjustment can well control the temperature of the water in the jacket through the temperature and flow of the circulating water, thereby controlling the quality of the old. The temperature adjustment effect of this kind of way is better, but since the old drum is always rotating, once the water supply device structure is unreasonable, it is easy to produce water leakage and even damage the structure of the old drum itself. And since the drum body is rotating, and the external inlet and outlet pipes are fixed, the temperature adjustment water hinge in the drum body is equipped with a set of dynamic and static combination device, all the sealing parts and rotating bearings are in the drum body, which is difficult to replace after long-term operation and wear. The product in the drum body is corrosive, the internal space is small, the temperature is high, and it is easy to lack oxygen. When workers enter the drum body to replace the vulnerable parts, the risk is great and it is difficult to meet the requirements of safe production. Practical new type content
