Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of drainage devices, and in particular relates to a mining filling drainage device. Background Art
[0002] Mine backfilling is a method of mine subsidence control that aims to fill the void by delivering fill material to the underground goaf, preventing surface subsidence and promoting the coordinated and integrated development of coal mining and the ecological environment. During the backfilling process, moisture accumulates within the backfill due to factors such as the humidity of the fill material, groundwater infiltration, and rainfall. If this moisture is not removed promptly, it can lead to reduced strength and stability of the backfill, and even cause safety accidents.
[0003] Artificial pumping and drainage is an important way to drain water from the filling area. However, during the pumping and drainage process, it is inevitable that a large amount of impurities such as mud, sand, and stones will be sucked into the pipes. These impurities can easily cause blockage in the pipes. Therefore, it is necessary to filter out the impurities mixed in the water at the initial stage of water flow. However, in the existing technology, the impurities that are filtered out and accumulated in the filtration equipment are generally filled back into the filling area after being removed. However, since these impurities have a high water content, if they are directly filled back into the filling area, it will greatly affect the drainage efficiency of the filling area. For this reason, we propose a mining filling drainage device with a drainage function. Utility Model Content
[0004] In response to the above problems, the purpose of the present utility model is to provide a mining filling drainage device, which can separate impurities in water extracted from the filling area, automatically collect and drain these impurities, and backfill the drained impurities into the filling area, thereby avoiding blockage of subsequent processing equipment and pipelines due to the mixing of a large amount of stones and soil in the extracted water, and automatically backfilling the separated impurities while reducing the water content therein, thereby avoiding refilling more water into the filling area and affecting the drainage efficiency.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a mining filling drainage device, comprising a base, a box body mounted on the top of the base via a support block, a support truncated platform mounted on the inner bottom of the box body, a screw seat mounted on the top of the support truncated platform, the top of the screw seat being threadedly connected to a stainless steel cylinder, a circular hole being provided between the inner and outer sides of the stainless steel cylinder, a first filter screen being sleeved on the outer side of the stainless steel cylinder, one side of the first filter screen being connected to a water inlet pipe, a motor being mounted on the top of the first filter screen, the output end of the motor being connected to a screw conveyor shaft, and one side of the first filter screen being connected to a solid output pipe, a first bracket being mounted on the top of the base, a spring damper being rotatably mounted on the inner side of the first bracket, the other end of the spring damper being rotatably connected to a drain basket, a second filter screen being provided inside the drain basket, a vibration motor being mounted on the bottom of the drain basket, an electric gate valve being mounted on the side of the drain basket, a bellows being connected between the bottom of the drain basket and the top of the box body, and a conveyor belt being provided on one side of the base.
