气控气球式高压粉料连续加料技术

PNEUMATICALLY CONTROLLED PERISTALTIC SOLIDS FEEDER FOR CONTINUALLY FEEDING POWDER INTO HIGH PRESSURE CONTAINER

本工作研制厂一种气控气球式高压粉料连续加料器．其工作原理是利用输料管中高压气球的放气与充气来代替机械阀门的开与关．输料管中等距离放置一连串气球，用定时计控制的电磁阀-高压气路，使奇数位及偶数位两组气球交替发生充气和放气，从而使粒状物料从气球上逐级下落，从常压容器连续不断输入高压容器或从高压容器连续不断输入低压容器。此种加料装置与以往的螺旋杆加料器及星形轮旋转加料器相比，具有操作简单，可连续加料，对粉料无磨损。

A pneumatically controlled peristaltic feeder for continually feeding powder into high pressure container has been developed. The working principle of this feeder is that blowing up and flatting down of the gasbags in a pipe take the place of closing and opening of the traditionally used mechanical valve. The gasbags are placed at same intervals and divided into two groups: odd number group and even number group. Each group of the gasbags is connected with the high pressure gas source and controlled by three-way solenoid valve-timer system. After the gasbags of odd number group have been blown up, and the transport pipe is sealed by the blown gasbags, the gasbags of even number group begin to be flatted down. As a result, the solid powder above the gasbags of even number group fall down and settle on the top of the filled gasbags of odd number group. Then gasbags of the even number group begin to be blown up. Through such operation in endless cycles, the solid powder fall down stage by stage from low pressure container into high pressure one or from high pressure container into low pressure container. Compared with the mechanical feeders such as scrow feeder and star type wheel feeder, this peristaltic feeder possesses the advantages of simpler operation, continually feeding, no wear to the. powder, and better sealing ability.
