    摘要： A vacuum filtration apparatus is provided with one or more vacuum chambers fixedly secured at predetermined positions. The interior of the vacuum chamber alternates between a partial vacuum and atmospheric pressure. An endless filter belt has a horizontal section disposed above the vacuum chamber. A slurry is fed from one or more slurry feeders onto the horizontal section of the endless filter belt so as to create a cake of solid particles. Water is fed from one or more water feeders onto the cake to wash the solid particles on the endless filter belt. The endless filter belt intermittently advances by a predetermined length. When the endless filter belt is stopped, the vacuum chamber is under a vacuum so as to draw the liquid constituent from the slurry, thereby obtaining a purified cake of the solid particles. The vacuum filtration apparatus is provided with a coupling bar at which the slurry feeder and the water feeder is attached. The coupling bar can reciprocate along the endless filter belt by the length of the intermittent advancement of the endless belt. Preferably, the coupling bar is connected to a belt advancing device so that the advancement of the endless filter belt causes movement of the slurry feeder and the water feeder in the direction which is the reverse of the direction of advancement of the endless filter belt.

    摘要翻译： 真空过滤装置设置有固定在预定位置的一个或多个真空室。 真空室的内部在部分真空和大气压之间交替。 环形过滤带具有设置在真空室上方的水平部分。 将浆料从一个或多个浆料进料器供给到环形过滤带的水平部分上，以产生固体颗粒的饼。 水从一个或多个给水器进料到蛋糕上以洗涤环形过滤带上的固体颗粒。 循环过滤带间歇地前进预定长度。 当环形过滤带停止时，真空室处于真空状态，以从浆料中抽出液体成分，从而获得固体颗粒的纯化饼。 真空过滤装置设置有连接杆，在该连接杆上连接有浆料供给器和给水器。 连接杆可以沿着环形过滤带往复运动一段长度的环形带的间歇进给。 优选地，联接杆连接到带前进装置，使得环形过滤带的前进使得浆料进料器和给水器沿与环形过滤带的前进方向相反的方向移动。
