Description

Discharging and recycling device Technical Field The utility model relates to the technical field of recovery devices, in particular to a discharge recovery device. Background The discharging and recycling device is industrial equipment integrating filtering, separating, adsorbing and regenerating functions, and is generally composed of a multi-stage treatment module, an intelligent control system and a corrosion-resistant pipeline system, and solid particles, liquid or gas components in waste materials are accurately separated through technologies such as physical screening, centrifugal sedimentation, chemical adsorption or membrane permeation, and valuable resources such as metal, solvents and energy sources are recycled. In the optical fiber coating production process, when the drawing of the prefabricated rod is finished and the rod is replaced, or before a vehicle is started to install a die after a long time of stopping, discharging operation is required to be carried out on a coating system pipeline. The main purpose of this operation is to eliminate the air bubbles of the coating mixture in the pipe, so as to avoid the occurrence of a large number of defects in the optical fiber coating layer during the drawing and starting process, and further to cause excessive waste of the product. However, when the rod is normally replaced at present, after the wire drawing is normally finished, the furnace is required to be cleaned again, the rod is replaced, the cone is cut, and the die is required to be cleaned until a new rod is started to pass through the die, and the time between the two steps is long, so that the residence time is required to be 4 hours. When the fiber drawing is completed, the coating system may stay for a longer period of time due to various uncontrolled external factors. After the pressure in the pipeline is stopped, air can enter the paint in the pipeline, and after the paint is mixed into bubbles, the wire drawing can cause coating defects. In order to reduce the scrappage of the optical fiber drawing, air bubbles in the pipeline need to be removed before the die is installed, and the inner and outer coating pipelines need to be discharged to remove the air bubbles. The normal bar replacement interval is 4 hours, and 2 to 3 kg of paint is required to be discharged, so that no bubble in a pipeline can be ensured, and after long-term shutdown, more paint is required to be discharged when a new tower opening line is started. Because the pipeline temperature is lower, no coating is filled after the pipeline is internally cleaned, no bubble in the pipeline can be ensured only by discharging up to 10-20 kg of coating, and because the internal coating and the external coating are mixed and discharged in one basin, a large amount of coating is wasted, and the production cost is not controlled.
