具体实施方式
下面结合附图描述本发明的具体实施方式。
如图1所示，带有深海单高压料仓给料设备的深海矿石水力提升系统，
包括注水泵1、注水立管2、深海单高压料仓给料设备3、提升立管4、脱水设备5以及管道6，注水泵1、脱水设备5固定在采矿船7上，注水泵1通过注水立管2连通深海单高压料仓给料设备3，深海单高压料仓给料设备3通过提升立管4连通脱水设备5，注水泵1与脱水设备5通过管道6连通。海面注水泵1为深海矿石水力提升系统泵入需要的压力和流量的海水，通过注水立管2，深海 单高压料仓给料设备3，提升立管4，脱水设备5以及管道6建立一个半闭环循环系统，实现了对海底生态环境的最低扰动。注水立管2和提升立管4可以是硬管、软管、或者硬管和软管组成的混合立管。
如图2所示，深海单高压料仓给料设备3包括从上至下依次连通设置的储料仓11、高压料仓12和给料仓13，给料仓13的出口连通高压管道10的，高压管道10的一端与注水立管2连通，高压管道10的另一端与提升立管4连通。储料仓11与高压料仓12之间设有填料阀16，高压料仓12与给料仓13之间设有卸料阀17。高压料仓12与高压管道10通过增压管道15连通，增压管道15上设有增压阀19。高压料仓12上设有泄压阀18。给料仓13与高压管道10之间设有给料设备14。给料设备14为螺旋给料机或者叶轮式给料机。以通过调节给料设备14的给料速度，按照需求实时调整矿浆中矿石的浓度，降低管道堵塞的风险。通过深海单高压料仓给料设备3上的各种阀门实现不间断给料，将矿石从储料仓11通过高压料仓12运转移到给料仓13，给料设备14将矿石按指定的量送入高压管道10内与海水混合，从而通过提升立管4将矿物提升到采矿船7上。
本发明的工作原理：打开采矿船7上的注水泵1，按照矿石水力提升系统需求的流量，将海水泵入注水立管2，海水通过注水立管2，经过深海单高压料仓给料设备3的高压管道10，然后回到提升立管4，到达采矿船7上的脱水设备5，然后海水再通过管道6回到注水泵1，形成一个海水循环系统。
本发明的工作过程：
开始前，深海单高压料仓给料设备3中的填料阀16、卸料阀17，泄压阀18和增压阀19处于关闭状态。然后采矿车将矿石输送到储料仓11里。
打开采矿船7上的注水泵1，按照矿石水力提升系统需求的流量，将海水泵入注水立管2，海水通过注水立管2，经过深海单高压料仓给料设备3的高压管道10，然后回到提升立管4，到达采矿船7上的脱水设备5，然后海水再通过管道6回到注水泵1，形成一个海水循环系统。
然后，打开高压料仓12的泄压阀18，待高压料仓12的内外压力平衡后，打开填料阀16，储料仓11里的矿石在重力的作用下落入高压料仓12内。待高压料仓12的矿石达到设定位置时，依次关闭填料阀16和泄压阀18，完成高压料仓12的填料作业。
打开高压料仓12与高压管道10之间的增压管道15上的增压阀19，使高压料仓12与高压管道10达到压力平衡。然后打开卸料阀17，高压料仓12内的矿石在重力的作用下进入给料仓13。
待高压料仓12内的矿石全部落入给料仓13后，依次关闭卸料阀17和增压阀19，完成高压料仓12的卸料作业。
给料设备14按照设定的给料速度，将给料仓13内的矿石送入高压管道10内和海水混合，形成混输矿浆20。混输矿浆20在高压水流的作用下，通过提升立管4被提升到采矿船7上的脱水设备5。通过脱水设备5将海水和矿石分离。注水泵1将分离出的海水重新泵入注水立管2，从而形成一个半闭环循环系统，实现海水的循环使用。
在高压料仓12完成卸料作业后，在阀门的配合下，重新开始新一轮的填料作业和卸料作业，以保证给料仓13内始终有一定量的矿石。如此循环，实现了不间断给料，并将矿石提升到采矿船上。
在整个过程中，只有在泄压和填料的过程中，会与周围环境产生极少量的海水交换，实现了对海底生态环境的最低扰动。
本发明利用采矿船上的注水泵，按照矿石水力提升系统需要的压力和流量，将海水泵入注水立管，然后利用深海单高压料仓给料设备，将矿石送入高压水力管道内与海水混合，然后将矿石和海水混合物提升到海面采矿船。利用采矿船上的脱水设备，将海水与矿物分离。海面注水泵将分离出的海水重新泵入注水立管，从而形成一个半闭环循环系统。本发明与海底环境产生极少量的海水交换，实现了对海底生态环境的最低扰动；深海单高压料仓给料设备通过重复填料作业和卸料作业，可以实现不间断给料，且运动部件少，可靠性高；海面注水泵扬程高，流量大，且易于保养和维修。使得本发明的水力提升系统更加环保，效率更高，扬程高，流量大，可靠性好，且易于保养和维修等特点。
