清洗设备;CLEANING APPARATUS

摘要

一种使用固体粒子材料清洗脏污基材之设备，包括：清洗空间；收集空间；泵送装置，具有泵入口；以及循环路径，藉此循环路径可使固体粒子材料及输送流体从收集空间经由泵送装置被转送到清洗空间。该设备又包括设在收集空间内之流量调节装置，并包括由至少一面壁界定之液通外壳、与泵入口连通之外壳出口以及设在液通外壳下侧，并配置成容许固体粒子材料及输送流体两者至外壳之至少一个粒子进入孔。本设备又可包括至少一个相对较小之流体进入孔，其仅配置来容许经由输送流体至液通外壳。; a collecting volume; a pumping device having a pump inlet; and a circulation pathway by which solid particulate material and a transporting fluid can be transferred from the collecting volume to the cleaning volume via said pumping device. The apparatus further comprising a flow regulating device disposed in the collecting volume and comprising a flow through enclosure defined by at least one wall, an enclosure outlet in communication with the pump inlet, at least one particle inlet orifice disposed at an underside of the flow through enclosure and configured to admit both solid particulate material and transporting fluid to the enclosure. The apparatus can further comprise at least one relatively smaller fluid inlet orifice configured only to admit transporting fluid to the flow through enclosure.
