A device for salvaging a filter in a drill hole in an in-situ leaching process comprises a main body and a hanging buckle, a connector is arranged at the upper end of the main body, a hole is laterally formed in the middle of the main body, an upper baffle is installed on the upper portion in the hole, a lower baffle is installed on the lower portion in the hole, and the hanging buckle is installed between the two baffles, can rotate and is connected with the upper baffle through a spring. When the hanging buckle is in an open state, the spring is in an open state. The in-situ leaching uranium mining filter can be quickly fished, the cost is low, the structure is simple, the operation is convenient, the situation that a drill hole cannot be used due to the problem of the filter is reduced, and the service life of the in-situ leaching process drill hole is prolonged. 一种地浸工艺钻孔内过滤器打捞装置，包括主体和挂扣，所述主体的上端设有接头，所述主体中间部位侧向开有孔，孔内上方装有上挡板，下方装有下挡板，所述挂扣装在两挡板之间可转动，并且通过弹簧和上挡板相连接，正常状态下，挂扣为打开状态，此时弹簧处于张开状态。本实用新型可实现地浸采铀过滤器的快速打捞，成
