Abstract
The utility model relates to the field of chemical-fiber equipment, and in particular relates to a polyester slurry adding device which can be used for refluxing EG (Ethylene Glycol) for flushing a slurry feeding pump into a slurry mixing tank. The polyester slurry adding device is characterized in that the slurry mixing tank is connected with a slurry circulating pump; the slurry circulating pump is respectively connected with a slurry feeding tank and a cleaning and refluxing pipeline of the slurry circulating pump; the cleaning and refluxing pipeline of the slurry circulating pump is connected with the slurry mixing tank; the slurry feeding tank is connected with the slurry feeding pump; a slurry outlet pipeline is connected to the slurry feeding pump; the cleaning and refluxing pipeline of the slurry feeding pump is connected to the slurry outlet pipeline; the cleaning and refluxing pipeline of the slurry feeding pump is connected with the slurry mixing tank. The polyester slurry adding device disclosed by the utility model can be used for refluxing the flushed-out EG and part of residual slurry in the pipeline into the slurry mixing tank for re-preparing, so that other media including water and the like can be not used for cleaning the pipeline in the whole production process. Besides, the pipeline-cleaning EG can be recycled, and the residual slurry in the pipeline also can be recycled.
Description
Technical field
The utility model relates to the chemical fiber machinery field, especially a kind of polyester slurry adding set.
Background technology
In existing polyester pulp add-on system, slurry feeds pump and slurry outlet pipeline and nozzle from slurry feeding tank by slurry and squeezes into reaction kettle of the esterification.In the situation that switchable pump but do not switch the pipeline nozzle is imported and exported pipeline to slurry feeding pump and is rinsed and brought puzzlement by fresh EG.By analysis, the main cause that causes this phenomenon is there is no the backflow of slurry pipeline on the slurry outlet pipeline of slurry feeding pump, and while causing fresh EG to be rinsed, EG can not return in slurry mix tank.Thereby cause the waste of fresh EG.The final cost that affects.
The utility model content
The purpose of this utility model is the deficiency in order to solve above-mentioned technology and provide a kind of EG that can make to rinse slurry feeding pump to be back to the polyester slurry adding set in slurry mix tank.
In order to achieve the above object, the polyester slurry adding set that the utility model is designed, it comprises slurry mix tank, the slurry circulating pump, the slurry circulating pump cleans reflux line, slurry feeding tank and slurry feeding pump, slurry mix tank is connected with the slurry circulating pump, the slurry circulating pump cleans reflux line with slurry feeding tank with the slurry circulating pump respectively and is connected, the slurry circulating pump cleans reflux line and is connected with slurry mix tank, slurry feeding tank is connected with slurry feeding pump, be connected with the slurry outlet pipeline on slurry feeding pump, be connected with slurry feeding pump and clean reflux line on the slurry outlet pipeline, slurry feeding pump cleans reflux line and is connected with slurry mix tank.
The length of in order to reduce slurry feeding pump, cleaning reflux line, reduce production costs, and described slurry feeding pump cleans reflux line and is connected to slurry mix tank by slurry circulating pump cleaning reflux line.
As optimization, at slurry feeding pump, clean on reflux line and be provided with shut off valve.
The resulting polyester slurry of the utility model adding set, be connected with slurry feeding pump and clean reflux line between slurry outlet pipeline and slurry mix tank, make residual backflow of slurry in the EG that develops and section of tubing enter slurry mix tank, reconfigured.Thereby make in whole production process, can not make other media such as water clear up pipeline, on the other hand, the EG of pipe blow-through can re-use, and slurry residual in pipeline also can be utilized again, is conducive to the reduction of production cost.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below by embodiment, the utility model will be further described by reference to the accompanying drawings.
