Abstract
Description
Technical Field
[0001] The invention belongs to the field of leather processing, and particularly relates to a sewage discharging device for a leather vacuum dryer. Background Art
[0002] When the drying platen of a vacuum dryer dries leather, a large amount of water flows from the drying platen to the sewage discharging device. The traditional sewage discharging device adopts drain pipes with drain holes provided at both ends of the drying platen, and the sewage in the drain pipes is discharged by evacuating the drain pipes through a vacuum system. Since the water contains leather fibers and dander, when it directly enters the drain pipe through the drain opening, it is easy to block the drain pipe and reduce the evacuation efficiency of the drain pipe. When the vacuum system is not working, the drain pipe is overfilled with water. When the vacuum system is started again, the sewage is easily directly pumped into the vacuum pump of the vacuum system. Since the sewage of leather has great corrosiveness, it causes corrosion after entering the vacuum pump, reducing its service life, and at the same time causing a reduction in vacuum degree and affecting the evacuation effect. Now, a sewage discharging device for a leather vacuum dryer is proposed to solve the above-mentioned problems. Summary of the Invention
