Description

Technical Field

[0001] The utility model relates to the technical field of tailings pond plugging in ore dressing technology, and more specifically to a bidirectional screw rod and double plugging plugging device for a drainage outlet of a drainage well of a tailings pond. Background Art

[0002] Drainage wells are set up in the tailings pond area. After the sedimentation in the tailings pond, the upper water enters the drainage tower from the drainage outlets around the drainage wells, and then flows into the main return water pump room through the drainage culvert dozens of meters deep at the bottom. It is transported back to the concentrator for recycling by pump power. However, as the water level in the reservoir area rises year by year, the lower drainage outlets need to be blocked to prevent the ore sand from entering the drainage wells due to the rise of ore sand and causing ore sand leakage.

[0003] However, the existing methods of sealing drainage inlets and outlets are mostly to manually go down the well to seal the drainage outlets, and most of them use wooden wedges and rubber plugs. The former wooden plugs are easy to rot and cause water seepage, and the latter requires drilling holes on the surface of the drainage well to install screws to fix the plugs, and drilling holes to install bolts is easy to damage the tower body. Utility Model Content

[0004] The purpose of the utility model is to solve the above technical problems and provide a bidirectional screw and double plugging plugging device for the drainage outlet of a tailings pond drainage well, which can achieve a good plugging effect on the drainage holes around the drainage well.

[0005] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical scheme: a bidirectional screw double plug sealing device for the drainage outlet of a tailings pond drainage well, comprising a tailings pond area and a drainage well, wherein the inner wall of the drainage well is provided with a plurality of drainage outlets, and a plugging device is installed between two opposite drainage outlets, wherein the plugging device comprises a hollow tube, both ends of the hollow tube are movably connected with screws, and the opposite ends of the two screws are penetrated and connected with plugs, and the end face of the plug close to the drainage well completely covers the drainage outlet.

[0006] Preferably, both ends of the hollow tube are fixedly connected with screw barrels, and the two screw barrels are respectively threadedly connected to one end of the two screw rods.

[0007] Preferably, a first limiting nut is fixedly mounted on the opposite ends of the two screw rods, and the diameter of the first limiting nut is smaller than the inner diameter of the drain outlet.

[0008] Preferably, a gasket is sleeved on the outer side of the screw, a second limiting nut is threadedly connected to the outer wall of the screw, and the gasket is located between the plug and the second limiting nut.

[0009] Preferably, the plug is made of elastic rubber.

[0010] The beneficial effects of the utility model are as follows:

[0011] 1. The two screws are respectively aligned with the two opposite drain ports, and then the two screws are screwed to make the two plugs away from the hollow pipe, and the two first limit nuts are respectively located inside the two drain ports, and the opposite sides of the two plugs are respectively in contact with the well wall of the drainage well, and the side of the plug completely covers the drain port, thereby completing the work of plugging the drain port, so that the device achieves the effect of simple structure and easy plugging;

[0012] 2. When there are multiple drainage outlets on the same horizontal line of the inner wall of the drainage well, the shape of the hollow tube can be changed, so that the ends of the hollow tube are multiple, so as to adapt to the multiple drainage outlets that need to be blocked on the same horizontal line.
