Abstract

The invention discloses a drum scraper dryer. The drum scraper dryer comprises a slag collection device for collecting the slag, the slag collection device comprises a slag collection hopper, a pressure valve and a vacuum valve are arranged on the slag collection hopper, the pressure valve comprises a pressure valve clack and a pressure rod, a pressure rotating block driving the pressure rod to rotate around the shaft axis of the pressure rod is connected to the pressure rod, the vacuum valve comprises a vacuum valve clack and a vacuum rod, a vacuum rotating block driving the vacuum rod to rotate around the shaft axis of the vacuum rod is connected to the vacuum rod, a pressure swing rod and a vacuum swing rod are respectively hinged to the pressure rotating block and the vacuum rotating block and hinged to the same linkage rod, the connecting line between the connecting point of the pressure rod and the pressure rotating block and the connecting point of the vacuum rod and the vacuumrotating block is parallel to the linkage rod, and the length of the connecting line is equal to the length of the linkage rod. The drum scraper dryer has the beneficial effects that the roller scraper dryer can operate the pressure valve and the vacuum valve simultaneously, so that the air pressure in the slag collection hopper is conveniently adjusted.

Description

technical field [0001] The invention relates to pentamethylenediamine production equipment, in particular to a drum scraper dryer. Background technique [0002] The main uses of pentamethylenediamine include polymer preparation, organic synthesis intermediate, epoxy resin curing agent, and biological research. At present, the biological production of pentamethylenediamine refers to direct fermentation or decarboxylation of lysine to produce pentamethylenediamine, and then the target product is separated from the raw material liquid. Among them, purification is a key step in isolating the target product. [0003] The Chinese patent with publication number CN105588407A discloses a drum scraper dryer. The drum scraper dryer includes a coaxial drum body and a rotating shaft, a power unit, a feed liquid pan, a feed liquid stirring device, a scraper, a slag collection device and a vacuum device. The drum shell, material liquid pan and scraper are all located in the vacuum devic...
