Description

Technical Field

[0001] The utility model belongs to the technical field related to viscose filament production, and particularly relates to an acid inlet dry pipe structure of an acid inlet system. Background Art

[0002] The high-speed continuous spinning of viscose filament production uses a closed reaction chamber for the reaction of acid and viscose. If there is a blockage, the thin glue will fill the reaction chamber in a short time, flow into the acid inlet hose and the acid inlet dry pipe, and condense in the acid pipe, affecting the acid bath flow, thereby affecting the spinnability. The acid inlet dry pipe needs to be cleaned regularly to ensure the stability of the acid inlet. In order to reduce the emission of sulfuric acid and reduce production costs, the acid bath is recycled after being mixed and filtered in the acid station workshop. Because the acid bath is highly corrosive, a tow filter is currently used for filtration, and fine impurities cannot be fully filtered. Long-term circulation will precipitate in the pipeline. When the acid bath fluctuates, it will enter the reaction chamber with the acid inlet hose, causing pollution or blockage, thereby affecting spinnability and product quality. The acid inlet dry pipe must be cleaned regularly, but it still has the following disadvantages in actual use:

[0003] The acid inlet pipe transports the acid to the viscose equipment. When the pipe needs to be cleaned, the machine needs to be shut down. During the operation, the acid is directly discharged from the pipe during cleaning, resulting in a waste of acid in the process of discharging the pipe.

[0004] The acid inlet main pipe transports acid to the viscose equipment. When cleaning, it is necessary to flush the cleaning water into the main pipe, and then extend the flushing water pipe into the acid inlet main pipe. After flushing with water, the main pipe is fully flushed. After flushing, the flushing pipe is taken out, which is not convenient enough. Utility Model Content

By arranging a main pipe body, a tee pipe, a balancing barrel and a sealing cover, the utility model solves the problems of waste caused by direct discharge of acid during cleaning of the acid inlet main pipe and the inconvenience of working due to the need for an additional flushing pipe to be inserted for flushing cleaning.

[0010] Furthermore, all the mounting screws are movably connected to a blind plate on their circumferential sides, the blind plate abuts against the mounting ring, the blind plate is threadedly connected to a fastening nut on the circumferential side of the mounting screw away from the outer side of the tee pipe, and the blind plate is installed together through the mounting screw and the fastening nut.

[0011] Furthermore, the input end of the balancing barrel is fixedly connected with an acid inlet pipe, a control valve is fixed on the peripheral side of the transfer pipe, and the balancing barrel transports the acid solution therein through the acid inlet pipe.

[0012] Furthermore, an acid discharge pipe is fixedly connected to the lower portion of the outer peripheral surface of the cover, the acid discharge pipe and the water inlet pipe are symmetrical to each other, and switch valves are fixed to the middle of the peripheral sides of the water inlet pipe and the acid discharge pipe.

[0013] The utility model has the following beneficial effects:

[0014] The utility model solves the problem of waste caused by direct discharge of acid liquid during cleaning of the acid inlet dry pipe by arranging a dry pipe main body, a balancing barrel and a sealing cover. When cleaning is required, firstly, the acid receiving container is placed under the acid discharge pipe, and the switch valve on the acid discharge pipe is opened.
