干混砂浆在向成品料仓 2'储存时， 它是通过提升机 1 '提升至料仓 2' 的顶部，并通过设于料仓 Ύ顶部的进料口 Ύ 1进入料仓 Ύ , 然后自由落体 运动至仓体中。 然而， 由于各种物料 (包括砂子、 水泥、 外加剂等)在空气 中的阻力不同， 这样会导致成品干混砂浆在下落过程中出现分层离析等现 象， 因而会极大影响砂浆的品质 o 发明内容
本发明要解决的技术问题是提供一种料仓装置， 该料仓装置能够减少 干混砂浆在料仓下落过程中出现的分层离析现象， 从而改善干混砂浆的品 质。 此外， 本发明另一个要解决的技术问题为提供一种包括上述料仓装置 的干粉砂浆搅拌站。

需要指出的是， 伸缩软管装置的内径根据干混砂浆提升机的输送能力 设定， 所述内径的大小应该可以使干混砂浆在软管内下落过程中具有很大 的填充率， 因而可显著减少干混砂浆在下落过程中发生的分层离析。

综上所述， 本发明所提供的料仓装置能够减少干混砂浆在料仓下落过 程中出现的分层离析现象， 从而改善干混砂浆的品质。 附图说明
图 1为现有技术中一种典型的料仓装置的结构示意图；
图 2为本发明一种实施例中料仓装置的结构示意图；
图 3为本发明另一种实施例中料仓装置的结构示意图。 具体实施方式
本发明的核心是提供一种料仓装置， 该料仓装置能够减少干混砂浆在 料仓下落过程中出现的分层离析现象， 从而改善干混砂浆的品质。 此外， 本发明另一个核心为提供一种包括上述料仓装置的干粉砂浆搅拌站。
为了使本领域的技术人员更好地理解本发明的技术方案， 下面结合附 图和具体实施例对本发明作进一步的详细说明。
请参考图 2, 图 2为本发明一种实施例中料仓装置的结构示意图。 在第一种实施例中， 本发明所提供的料仓装置， 包括料仓 2, 料仓 2 设有进料口 21 ; 在现有技术的基础上， 料仓 2的内部进一步设有与进料口 21连通的伸缩软管装置 3 , 伸缩软管装置 3的下端设有出料口 31 ; 所述料 仓装置还包括动力装置， 所述动力装置驱动伸缩软管装置 3在竖直方向上 伸缩。
需要指出的是， 在理想状态下， 伸缩软管装置 3的内径根据干混砂浆 提升机 1的输送能力、 干混砂浆的流动系数和干混砂浆的堆密度等因素确 定， 一般说来， 提升机 1的输送能力越大， 伸缩软管装置 3的内径越大， 提升机 1的输送能力越小， 伸缩软管装置 3的内径越小； 干混砂浆的流动 系数越大， 即干混砂浆的流动性越好， 伸缩软管装置 3的内径越小， 干混 砂浆的流动系数越小， 即干混砂浆的流动性越差， 伸缩软管装置 3的内径 越大； 干混砂浆的堆密度越大， 伸缩软管装置 3的内径越小， 干混砂浆的 堆密度越小， 伸缩软管装置 3的内径越大。
需要说明的是， 在理想状态下， 本领域的技术人员根据公知常识和公 用定理， 并根据提升机 1的输送能力等已知条件， 是可以计算出伸缩软管 装置 3的内径的理想数值， 但是这个理想数值并不能作为对本发明保护范 围的限制， 一般说来， 伸缩软管装置 3的内径满足以下条件即可： 内径的 大小应该可以使干混砂浆在软管内下落过程中具有很大的填充率， 因而可 显著减少干混砂浆在下落过程中发生的分层离析现象。
此外，需要说明的是，伸缩软管装置的伸缩要具有适当速度，所述 "适 当速度" 是指与已有物料 5表面上升的速度相同， 或者虽然小于已有物料 5表面上升的速度， 但是能够保证出料口 31不被逐渐上升的物料淹没； 当 然， 所述 "适当速度" 略大于已有物料 5表面上升的速度也是可以的。
如图 2所示， 干混砂浆成品料通过提升机 1提升至料仓 2顶部， 并通 过料仓 2顶部的进料口 21进入伸缩软管装置 3中， 由于伸缩软管装置 3 具有适当的内径， 成品料在伸缩软管装置 3下落的过程中具有很大的填充 率， 因而在软管下降过程中会显著减少分层离析现象的发生。
开始落料时， 伸缩软管装置 3可以在不影响落料的范围内尽可能地伸 长，从而使得伸缩软管装置 3的出料口 31与料仓 2中已有物料 5表面之间 的高度尽可能降低， 从而减少干混砂浆发生分层离析的高度行程； 随着进 料， 料仓 2中已有物料 5的表面连续升高， 此时伸缩软管装置 3回缩， 从 而在料仓 2进料的过程中， 显著减少了干混砂浆下落过程中出现的分层离 析现象。 当料仓 2中已有物料 5的料位下降时，此时伸缩软管装置 3伸长， 使得伸缩软管装置 3的出料口 31与料位之间保持适当的距离。
此外，成品干混砂浆在伸缩软管装置 3的出料口 31集中出料，这种方 式也可显著减少干混^^浆分层离析现象的产生。
需要指出的是， 在本实施例中， 对于伸缩软管装置 3的最大伸长长度 并不做限制， 显然， 伸缩软管装置 3的最大伸长长度越大， 则在刚开始进 料时，伸缩软管装置 3的出料口 31越接近料仓 2的底部，并随着落料伸缩 软管装置 3逐渐回缩， 这种设置方式具有较好的技术效果。
当然， 伸缩软管装置 3的最大伸长长度仅为料仓 2竖直长度的一半， 或者小于料仓 2竖直长度的一半， 此时也能有助于减少部分干混砂浆发生 的分层离析现象， 因而也能解决技术问题， 实现发明目的。
在上述实施例中，我们可以具体设定伸缩软管装置 3的最大伸长长度， 具体地， 所述伸缩软管装置 3达到最大伸长极限时， 其出料口 31与料仓 2 底部之间的距离在预定高度范围之内。
需要说明的是， 上述预定高度具有如下内涵： 所述干混砂浆在所述预 定高度范围内自由下落时会显著减少分层离析现象的发生。
请参考图 3 , 图 3为本发明另一种实施例中料仓装置的结构示意图。 在上述第一种实施例中， 我们可以作进一步改进， 从而得到本发明的 第二种实施例。
在第二种实施例中， 所述料仓装置还包括料位检测装置 4和控制装置
(图中未示出）；
料位检测装置 4用于检测料仓 2中已有物料 5的料位高度， 并发出料 位信号； 控制装置用于接收来自料位检测装置 4的料位信号， 并根据该料 位信号发出指令； 伸缩软管装置 3的动力装置根据所述控制装置发出的指 令， 驱动伸缩软管装置 3伸缩， 以便伸缩软管装置 3的出料口 31与料仓 2 内已有物料 5的表面之间保持在所述预定高度范围之内。 在此， 所述 "预 定高度" 的内涵与上述 "预定高度" 的内涵相同。
随着落料的连续进行， 料仓 2内已有物料 5的表面逐渐升高， 料位检 测装置 4连续发出料位信号， 并将信号反馈给控制装置， 控制装置根据该 连续料位信号发出指令给动力装置， 该动力装置驱动伸缩软管装置 3逐渐 回缩， 一般说来， 料仓 2内已有物料 5表面升高的速度大体等于伸缩软管 装置 3 回缩的速度， 只有这样， 才可以保证伸缩软管装置 3 的出料口 31 与料仓 2内已有物料 5的表面之间保持预定高度。
显然， 该实施例在不发生或者显著减少干混砂浆发生分层离析的基础 上， 实现了料位的自动检测， 并实现了伸缩软管装置 3的自动伸缩控制， 具有较高的智能化水平。
此外， 在料仓 2中已有物料 5的料位逐渐下降时， 料位检测装置 4连 续发出料位信号， 并将信号反馈给控制装置， 控制装置根据该连续料位信 号发出指令给动力装置， 该动力装置驱动伸缩软管装置 3逐渐伸长， 一般 说来， 伸缩软管装置 3伸长的速度大体等于料仓 2内已有物料 5表面下降 的速度， 这样可以保证伸缩软管装置 3的出料口 31与料仓 2内已有物料 5 的表面之间保持预定高度。
在此需要说明的是，本实施例对于料位检测装置 4的类型并不做限制， 对于料位检测装置 4的设置位置也不作限制， 因而各种类型的料位检测装 置 4, 以及能够实时检测料位高度的各种设置位置均在本实施例的保护范 围之内。 请参考图 3 , 在上述第二种实施例中， 我们可以具体设定料位检 测装置 4的设置位置， 具体地， 该料位检测装置 4设于料仓 2的顶壁。 这 种设置方式既便于料位检测装置 4的维护， 同时也便于料位检测装置 4的 各种线路的布置。
当然，料位检测装置 4还可以设置在伸缩软管装置 3的出料口 31的侧 壁， 此时， 该料位检测装置 4检测到的料位高度即为伸缩软管装置 3的出 料口 31与料仓 2内已有物料 5的表面之间高度。
当该高度大于所述预定高度时， 控制装置可以控制伸缩软管装置 3伸 长， 当该高度小于所述预定高度时， 控制装置可以控制伸缩软管装置 3收 缩，使得伸缩软管装置 3的出料口 31与料仓 2内已有物料 5的表面之间高 度大体等于所述预定高度。
在上述任一种实施例中 ,我们可以对料位检测装置 4的类型做出限定， 具体地， 该料位检测装置 4可以为超声波连续料位计， 这种料位计具有较 高的检测精度。 当然， 其他类型的料位检测装置 4也在本发明的保护范围 之内。
此外， 本发明所提供的干粉砂浆搅拌站包括上述任一个具体实施例所 描述的料仓装置； 所述干粉砂浆搅拌站的其他部分、 及所述料仓装置与该 其他部分之间的结构关系可以参照现有技术， 本文不再展开。 以上对本发明所提供的一种料仓装置及包括该装置的干粉砂浆搅拌站 了阐述，以上实施例的说明只是用于帮助理解本发明的方法及其核心思想。 应当指出， 对于本技术领域的普通技术人员来说， 在不脱离本发明原理的 前提下， 还可以对本发明进行若干改进和修饰， 这些改进和修饰也落入本 发明权利要求的保护范围内。
