Description

一种超声波式的岩盐连续清洗装置和方法 技术领域
本发明公开了岩盐清洗设备技术领域，提供了一种超声波式的岩盐连续清洗装置和方法。
背景技术
岩盐是一种天然形成的可直接食用的矿盐，氯化钠成分在98％以上，其余元素包括铁、钙、镁、钾、铝、锌、镓、硅等数十种人体所需矿物质。其中以喜马拉雅岩盐为典型。喜马拉雅岩盐主要产于喜马拉雅山脉地区，是从喜马拉雅山脉600米深矿中开采出来的盐，是世界上藏量最大和纯度最高的水晶盐矿藏，也是一种稀缺的资源。喜马拉雅岩盐是目前是国外市场上主流的岩盐类产品，其作为原料的盐制品发展速度非常快，除了食用,还可用于美容养生,具有很大的开采价值。但是因为其本身的晶体结构原因，在开采过程中会形成不规则的形状，同时会产生裂纹、缝隙和孔隙等，容易带入灰尘、泥土等污渍，所以在生产过程中需要对岩盐进行清洗。目前仅能用传统的吹式清洗、浸润式清洗、刷子清洗和喷淋清洗配合清洗液对岩盐进行处理。这些清洗方式并不能有效清除附着在表面的污渍以及掉在岩盐块缝隙中的污渍，对岩盐的开采使用有一定的限制；使用传统的清洗液的处理过程中无针对性的清洗岩盐，造成水资源的浪费，盐水排放则会对环境造成很大污染。同时传统的清洗岩盐方式普遍存在人力成本高，清洗效率低，得到的岩盐清洗质量不可控的问题。
发明内容
本发明的目的在于：针对上述岩盐清洗处理方法因为技术落后导致的过程繁琐、清洗效率低、不环保、不节能、产品清洗质量稳定性差的问题，本发明提供了一种高效率、环保节能、有针对性清洗、较节省人力成本的超声波式的岩盐连续清洗装置和方法。
本发明采用的技术方案如下：
对岩盐进行上料预检、预清洗；
预清洗完成后，对岩盐进行超声波清洗，完成超声波清洗；
超声波清洗完成后，对岩盐进行干燥，完成岩盐的干燥处理；
干燥处理后,对岩盐下料检测，完成整个清洗过程。
在岩盐上料预检时，对岩盐进行图像信息采集，将采集到的图像信息与预设的图像信息进行对比，得到岩盐污染程度，并根据污染程度调节预清洗时的水压和清洗时间。
在岩盐下料检测时，对岩盐进行图像信息采集，将采集到的图像信息与预设的图像信息进行对比，得到岩盐污染程度，污渍程度超过预先的设定值的判断为不合格岩盐，根据不合格岩盐数量控制超声波清洗的频率。
全程清洗液污染感应、监测、处理,具体地，超声波清洗模块3设置有排水口、溢流口、排污口和液体浊度检测装置22；液体浊度检测装置22将检测到的信息反馈到自动控制模块10，更换超声波清洗模块中的清洗液。
具体地，一种超声波式的岩盐连续清洗装置和方法，在上料预检模块1和下料检测模块7均设有图像污渍检测装置13，所述上料预检模块1的图像污渍检测装置13采集到岩盐的图像信息，并将信息通过传输线44传输到自动控制模块10，自动控制模块10通过与预先设定的图像信号进行对比，调节预清洗模块2的变频控制水泵19来控制每一个喷嘴15的压力和清洗时间。岩盐经过预清洗模块2的处理后，进入超声波清洗模块3。
超声波清洗模块3的超声波振子21和液体浊度检测装置22分别和自动控制模块10相连，自动控制模块10根据液体浊度检测装置22检测的清洗液的混浊度，与设定值进行对比，当大于设定值时，增加超声波清洗模块3的变频控制水泵19的进出水流量，从而更换超声波清洗槽20中的清洗液。
岩盐经过超声波清洗模块3后，可选地，再经过一个漂洗模块4，达到更好的清洗效果。
岩盐经过超声波清洗模块3后，再经过干燥模块6，干燥模块6包括高压风刀切水工位和热风烘干工位，可以避免岩盐的有效成分的流失。再进入下料检测模块7。
所述下料检测模块7的图像污渍检测装置13采集到岩盐的图像信息，并将信息通过传输线44传输到自动控制模块10,当岩盐上的污渍程度超过预先的设定值时，自动控制模块10会发出报警声，提示质量检验人员该处盐块不合格；根据不合格岩盐数量控制超过预设值，自动控制模块10发出信号，自动调节超声波清洗模块3，提高超声波振子21的频率，增强超声波清洗的效果；当不合 格岩盐数量占比超过预先的设定值，也发出另一种警报声，提示质量检验人员密切注意设备的性能。
漂洗模块4和超声波清洗模块3的清洗液通过水净化装置处理后，进入待处理水槽33，通过净化装置后，再循环到漂洗模块4。
优选地，清洗过程中的清洗液是饱和食盐水，超声波功率采用的功率密度为16W/L。饱和食盐水不会溶解岩盐的有效成分，食盐水的密度较大，表面张力比较大，黏度较纯水高，所以清洗液产生空化作用的空化阀大，故在超声波功率采用的功率密度为16W/L，在这种功率密度下，通过可调节功率来调整空化效应的强度，达到最优的清洗效果。
整个清洗过程中的清洗液通过水净化装置处理后，再通过循环到漂洗模块4，实现清洗液的循环使用。
可选地，所述预清洗模块2、漂洗模块4可采用高压喷淋式。
可选地，设置有排风模块8，所述预清洗模块2、超声波清洗模块3、漂洗模块4和干燥模块6的上端和排风管道40相连，排风风机39通过排风管道40抽出每个工位段产生的水雾和冷空气，并通过冷凝器41重新凝结成水。
可选地，所述图像污渍检测装置13可以采用相机或者摄像机。其中支撑架42和上料预检模块的支架焊接为一个刚体；图像污渍检测装置13固定在支撑架42上；图像污渍检测装置13有护罩45保护；相机通过传输线44同自动控制模块10相连。
综上所述，由于采用了上述技术方案，本发明的有益效果是：
1、本发明利用超声波来清洗岩盐，可以达到更好的清洗效果。
2、本发明通过对岩盐污染程度进行识别，并通过污染程度调节调节水压和清洗时间，使得对清洗对象针对性作业，节约能源，且清洗效果好。
3、本发明对清洗后的岩盐的清洁程度进行识别，如清洁程度不满足需求，则调节超声波振子的频率，使得超声波清洗更加精确，提高了清洗质量，同时更节约能源。
4、上料预检模块设有图像污渍检测装置，节约了岩盐清洗过程中的清洗液的使用，同时有针对性的清洗岩盐，使得岩盐的清洗效果更好。
5、下料检测模块的图像污渍检测装置，实现了对岩盐清洗质量的控制，可 以得到清洗质量更好的岩盐。
6、全程清洗液污染感应、监测、处理系统，对清洗液实施全程监控，保持清洗液的洁净程度，达到更好的清洗效果。

清洗过程中的清洗液是饱和食盐水，超声波功率采用的功率密度为16W/L。 饱和食盐水不会溶解岩盐的有效成分，食盐水的密度较大，表面张力比较大，黏度较纯水高，所以清洗液产生空化作用的空化阀比较大，故在超声波功率采用的功率密度为16W/L，在这种功率密度下，通过可调节功率来调整空化效应的强度，达到最优的清洗效果。
全程清洗液污染感应、监测、处理,具体地，超声波清洗模块3设置有排水口、溢流口、排污口和液体浊度检测装置22；液体浊度检测装置22将检测到的信息反馈到自动控制模块10，更换超声波清洗模块中的清洗液。
所述循环模块9,具体地，在待处理水槽旁33设有水泵34。高压喷淋漂洗工位4从高压喷淋漂洗储液槽24中抽取清洗液用于对喜玛拉雅岩盐的喷淋漂洗，漂洗后的清洗液通过高压喷淋漂洗槽23和管道进入喷淋预洗储液槽18，喷淋预洗储液槽18中清洗液用于对喜玛拉雅岩盐的预洗和超声波清洗，之后清洗液通过喷淋预洗槽17、超声波清洗槽20和管道进入待处理水槽33。待处理水槽33的清洗液通过水泵34抽取依次通过石英砂过滤器16、活性炭过滤器16、紫外线杀菌37和安保过滤器16，又循环回到高压喷淋漂洗储液槽24。整套自动水循环处理设备系统10中，仅需要定期补充新鲜的清洗液到高压喷淋漂洗储液槽24，同时将过滤器过滤出的固体物质进行处理，达到安全、环保和节能的效果。
所述排风模块8包括排风风机39、排风管道40、冷凝器41。排风管道40一端分别同预清洗模块2、超声波清洗模块3、漂洗模块4和干燥模块6相连，一端与排风风机39相连，排风风机39与冷凝器41相连。排风风机39通过排风管道40抽出预清洗模块2、超声波清洗模块3、漂洗模块4和干燥模块6产生的水雾，并通过冷凝器41重新凝结成水，回到高压喷淋预洗储液槽18。
本说明书中公开的所有特征，除了互相排斥的特征和/或步骤以外，均可以以任何方式组合。
