具体实施方式
现在，将参照附图更详细地描述根据本申请的示例性实施方式。然而，这些示例性实施方式可以由多种不同的形式来实施，并且不应当被解释为只限于这里所阐述的实施方式。应当理解的是，提供这些实施方式是为了使得本申请的公开彻底且完整，并且将这些示例性实施方式的构思充分传达给本领域普通技术人员。
需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。下面将参考附图并结合实施例来详细说明本申请。
请参考图1至图3，根据本申请的自冲洗箱，可以是油箱或水箱，其包括箱体9，箱体9上设置有进液口6和出液口，自冲洗箱还包括：至少一个排屑部1，排屑部1具有排屑面2，排屑面2的至少部分倾斜于水平面，排屑部1设置在箱体9的内侧并位于箱体9的底部；泄液口3，用于排出位于箱体9内的冲洗液，泄液口3位于排屑部1的至少部分的下方，以使由排屑面2滑下的碎屑杂质经泄液口3排出；加热装置4，加热装置4安装在箱体9上，用于加热位于箱体9内的冲洗液。
本申请提供的自冲洗箱可以是油箱或水箱，与之对应，冲洗液可以为液压油或水。在本实施例中，自冲洗箱为自冲洗油箱，其包括箱体9，箱体9上设置有进液口6和出液口，自冲洗箱还包括：至少一个排屑部1，排屑部1具有排屑面2，排屑面2的至少部分倾斜于水平面，排屑部1设置在箱体9的内侧并位于箱体9的底部；泄液口3，用于排出位于箱体9内的冲洗液，泄液口3位于排屑部1的至少部分的下方，以使由排屑面2滑下的碎屑杂质经泄液口3排出；加热装置4，加热装置4安装在箱体9上，用于加热位于箱体9内的冲洗液。箱体9内的碎屑杂质在重力作用下沿着排屑部1的排屑面2滑下，聚集到排屑面2的底部，并通过泄液口3排出到箱体9的外部，防止碎屑杂质在箱体9内部积累和沉积最终难以清理，并有利于保持油路清洁，提高液压油在油路中的循环效率。加热装置4可以对箱体9内的冲洗液进行加热，降低箱体9内的冲洗液的黏度，使冲洗液中的碎屑杂质更容易在重力作用下沿着排屑面2下滑并由泄液口3排出，进而有利地减少了杂质碎屑粘接于油箱的底部的情况，解决了现有技术中的箱的底部易于粘接碎屑杂质且难以清洗的问题。
具体地，排屑面2的至少部分为平面或曲面。这样设置，可以供碎屑杂质沿着排屑面2滑下。
本实施例中，排屑部1的数量为两个，两个排屑部1的排屑面2均为平面，两个排屑部1的排屑面2呈V字形布置，两个排屑部1的最高端分别与箱体9的两个侧壁一一接触，两个排屑部1的最低端均与箱体9内壁的底面接触。这样可以使箱体9内的碎屑杂质沿两个排屑面2下滑并聚集在V形结构的底部，方便将碎屑杂质统一排出。
为了保证箱体9内的碎屑杂质可以随着冲洗液充分地排出，泄液口3位于箱体9的底面，或泄液口3位于箱体9的侧壁的底部。在本实施例中，如图2和图3所示，泄液口3位于箱体9的侧壁的底部。这样可以使冲洗箱体9的冲洗液从泄液口3充分流出，进而将碎屑杂质携带排出。
在本实施例中，如图3所示，加热装置4包括多个加热管，各个加热管均穿设在排屑部1 上，各个加热管对排屑部1进行加热，排屑部1在通过热传导对靠近其周围的冲洗液进行加热，提高排屑部1附近乃至整个箱体9内部的冲洗液的温度，降低了冲洗液的黏度，进而使碎屑杂质更容易沿排屑部1的排屑面2下滑，提高了对碎屑杂质的排出效果。
具体地，每个排屑部1上穿设三个加热管，各个加热管均水平设置，各个加热管之间的距离相等，且各个加热管的长度方向与排屑部1的长度方向一致。这样可以保证加热管对排屑部1各个部分加热的均匀性，避免排屑部1周围冲洗液温度差异较大而影响箱冲洗效果。
为了加强箱体9内冲洗液的流动，提升对箱体9内的碎屑杂质的冲洗效果和箱体9内的冲洗液循环效果，自冲洗箱还包括：驱动装置5，驱动装置5的至少部分位于箱体9的内部，驱动装置5的至少部分用于伸入位于箱体9内的冲洗液内，以驱动位于箱体9内的冲洗液流动。箱体9内的冲洗液可以在驱动装置5的驱动作用下产生流动，对箱体9内壁起到冲刷的作用，可以使箱体9内壁沉积的碎屑杂质被冲洗下来，实现较好的冲洗效果。
具体地，如图3所示，驱动装置5包括：叶轮，叶轮可转动地设置在箱体9内；电机，电机与叶轮连接，以通过驱动叶轮转动，以使叶轮带动位于箱体9内的冲洗液流动。叶轮的轴可以沿任何方向设置，在本实施例中，叶轮的轴向与排屑部1的长度方向一致，以提高对排屑面2处的碎屑杂质的冲洗效果。
为了提高驱动装置5的驱动能力，增大驱动装置5的作用范围，驱动装置5还包括：伸缩部，伸缩部的至少部分沿竖直方向可伸缩地设置，伸缩部的一端固定在自冲洗箱上，伸缩部的另一端位于箱体9的内侧，电机和叶轮均安装在伸缩部上，以通过控制伸缩部进行伸缩运动使伸缩部带动叶轮和电机移动。
在本实用新型中，伸缩部可以采用多种实现方式：
在第一种实现方式中，伸缩部为电动伸缩杆，其包括导套和安装在导套内并可沿导套滑入和滑出的推杆，由用于驱动该伸缩部伸缩的驱动电机通过机械传动最终驱动推杆沿导套进行滑动伸缩，以实现伸缩部的伸缩。更具体的一种电动伸缩杆的结构及工作过程为，驱动电机固定在导套上，驱动电机的输出轴与丝杆连接，丝杆上装有丝杆螺母，丝杆螺母与推杆连接，这样，通过固定在导套上的驱动电机带动丝杆转动，从而驱动丝杆螺母和推杆沿丝杆运动，进而实现伸缩功能。通过电动伸缩杆带动电机和叶轮上下移动，扩大了驱动装置的作用范围，有利于加强箱体9内的冲洗液流动，提高对碎屑杂质的冲洗效果。
在第二种实现方式中，伸缩部为气动伸缩杆，其包括导套和安装在导套内并可沿导套滑入和滑出的推杆，通过气压驱动推杆沿导套进行滑动伸缩，以实现伸缩部的伸缩。
在第三种实现方式中，伸缩部为液压伸缩杆，其包括导套和安装在导套内并可沿导套滑入和滑出的推杆，通过液压驱动推杆沿导套进行滑动伸缩，以实现伸缩部的伸缩。
为了能够准确的控制驱动装置5的位置和电机的转向和转速，良好地适应液压油循环作业以及油箱冲洗作业，驱动装置5还包括：控制器，控制器与电机和伸缩部均连接，用于控制电机和/或伸缩部的动作。控制器设置在箱体9上，控制器设有人机交互面板，通过人机交 互面板可以给控制器输入控制参数，进而通过控制器实现对电机的转向、电机的转速、驱动装置5的位置等参数的控制，确保驱动装置5处于最佳工作状态。
为了能方便地补充液压油，以及在箱体9冲洗过程中方便地注入冲洗液，如图2所示，箱体9还包括注液口7。注液口7设置在箱体9的侧壁的上方。
考虑到箱体9结构的合理性，使箱体9拆卸、维护更方便，如图1至图3所示，自冲洗箱还包括：箱盖10，箱盖10与箱体9可拆卸连接，驱动装置5安装在箱盖10的内侧。优选地，箱体9和箱盖10之间通过螺栓连接。通过拧松螺栓将箱盖10拆卸后，可以方便地对箱体9内部进行清理或对箱体9内的驱动装置5进行维修等操作。
具体地，自冲洗箱还包括流量计8，流量计8与出液口连接，用于计量从出液口流出的液压油的流量。操作人员通过观察流量计8可以直观地了解液压油在油路中的循环情况。
为了提高箱体9的结构强度，箱体9还包括支撑架，支撑架固定安装在箱体9的底部，用于对箱体9进行结构加强，支撑架的延伸方向与箱体9的长度方向相同。
本实施例的箱体9在使用过程中，当箱体9进行液压油循环作业时，控制装置控制伸缩部分收缩，并控制电机以设定的速度旋转，加强箱体9内液压油的循环效果。
当需要对箱体9进行冲洗时，停止制冷系统的运行，关闭进液口6、出液口和泄液口3，打开注液口7，通过注液口7向箱体9中注入冲洗液，控制器控制伸缩部分伸长带动电机和叶轮移动到箱体9下部，控制器控制电机和加热管工作，驱动箱体9内的冲洗液流动并对冲洗液进行加热，将箱体9内的碎屑杂质冲洗下来。然后，控制器控制电机停止转动，碎屑杂质在重力作用下沉降到排屑面2的V形结构底部，通过打开泄液口3便可以将碎屑杂质排出，完成对箱体9的冲洗。
本申请还提供了一种机床冷却机，包括自冲洗箱，其中，自冲洗箱为上述的自冲洗箱。
从以上的描述中，可以看出，本申请上述的实施例实现了如下技术效果：
本申请中的自冲洗箱解决了现有技术中的碎屑杂质粘于箱体底部难于清洗以及聚集在箱底部的碎屑会通过管路进入系统参与循环而影响系统的循环特性的问题，可以冲洗掉冲洗液在循环过程中携带的碎屑杂质，并通过泄液口排出杂质，方便对机床油冷机箱装置中的碎屑杂质的清洗，并有利于保持油路清洁，提高了液压油在油路中的循环效率。
以上仅为本申请的优选实施例而已，并不用于限制本申请，对于本领域的技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
