Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mine tailings pond flood discharge and return water systems, in particular to a tailings pond return water antifreeze device. Background Art
[0002] Tailings ponds are places used to store tailings discharged after ore sorting in metal and non-metal mines. In cold areas, the winter backwater of tailings ponds is mostly done by manually removing the frozen layer around the backwater structure or placing submersible pumps under the ice to pump the tailings water under the ice into the backwater structure.
[0003] Tailings ponds in cold regions are prone to thick ice formations in winter, and dynamic ice pressure often adversely affects the structural safety of the return water structure. Manually chipping away the frozen layer around the return water structure is not only prone to damage, but also dangerous to operate on ice. Furthermore, manual ice breaking is time-consuming and labor-intensive, making it difficult to guarantee normal production operations. Placing submersible pumps under the ice to pump tailings water from the ice into the return water structure makes it difficult to guarantee the required return water volume for production, and failure of the submerged pumps cannot be promptly repaired, impacting production.
[0004] In view of this, the present utility model is proposed. Utility Model Content

[0007] A tailings pond backwater antifreeze device includes a backwater structure, a floating ring around the backwater structure, and a submersible pump;
[0008] The floating ring around the backwater structure floats in the clarified water area of the tailings pond and surrounds the backwater structure. A circle of floating ring guardrails is provided on the floating ring around the backwater structure.
[0009] The submersible pump is arranged in the water of the tailings pond and is connected to a return water antifreeze main pipe, which is arranged around the return water structure. A plurality of antifreeze branches are extended from the return water antifreeze main pipe.
[0010] Preferably, the return water antifreeze main pipe is fixed on the floating ring guardrail.

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The components of the embodiments of the present invention generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the utility model for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present invention.
[0026] like Figure 1-3 As shown, an embodiment of the present invention provides a tailings pond return water antifreeze device, comprising a return water structure 3, a floating ring 5 surrounding the return water structure, and a submersible pump (not shown). In the present invention, the submersible pump is disposed in the submersible water area below the ice or in the unfrozen water area of the tailings pond. A return water antifreeze main pipe 1 is connected to the submersible pump. The submersible pump draws water from the tailings pond into the return water antifreeze main pipe 1. The return water antifreeze main pipe 1 is arranged in a circle around the return water structure 3. A plurality of antifreeze branches 2 are arranged at intervals on the return water antifreeze main pipe 1, so that the water in the return water antifreeze main pipe 1 can flow out along the antifreeze branches 2.
[0027] In the above embodiment, the utility model provides a tailings pond return water antifreeze device in which a return water antifreeze main pipe 1 is provided around the return water structure 3, and a plurality of antifreeze branches 2 are extended from the return water antifreeze main pipe 1. The outflow of water through the antifreeze branches 2 causes the tailings water around the return water structure 3 to flow continuously, thereby preventing the tailings water from freezing. This avoids the safety hazard of manually removing the ice layer, ensures the return water volume required for production, and is safe and convenient to maintain.
[0028] In the above embodiment of the present invention, the floating ring 5 around the backwater structure floats in the clarified water area of the tailings pond and surrounds the backwater structure 3. A circle of floating ring guardrails 6 is provided on the floating ring 5 around the backwater structure. During the actual construction process, the floating ring 5 around the backwater structure will continue to rise as the water level of the tailings pond rises. At the same time, the backwater structure water inlet 4 below the backwater structure 3 can be sealed with a concrete plug, and the backwater structure water inlet 4 above the backwater structure is still used for backwater.
[0029] In a preferred embodiment of the present invention, the return antifreeze main pipe 1 is fixed to the floating ring guardrail 6. This not only effectively secures the return antifreeze main pipe 1, but also ensures that both the return antifreeze main pipe 1 and the antifreeze branch pipe 2 remain above the tailings reservoir water level as it rises. Furthermore, the end of the return antifreeze main pipe 1 is sealed, ensuring smoother flow through the antifreeze branch pipe 2.
[0030] In another preferred embodiment of the present invention, a drain flow rate regulating valve 7 is provided on the antifreeze branch pipe 2, and the drain flow rate regulating valve 7 can be used to adjust the water flow rate in the antifreeze branch pipe 2 at any time. In this way, when dealing with different temperature weather, the water flow rate can be adjusted to ensure that the water area of the tailings pond is not easy to freeze in winter.
[0031] In another preferred embodiment of the present invention, the dimensional parameters of the antifreeze branch pipe 2 and the return antifreeze main pipe 1 are as follows: the outlet of the antifreeze branch pipe 2 is 0.3 to 0.4 meters above the water surface of the tailings pond. The antifreeze branch pipes 2 are arranged on the return antifreeze main pipe 1 at intervals of 0.5 to 1.0 meters. The inner diameter of the return antifreeze main pipe 1 is 60 to 100 mm. The inner diameter of the antifreeze branch pipe 2 is 30 to 50 mm.

These terms are intended solely to facilitate the description of this utility model and to simplify the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third," etc., are used solely to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0033] Furthermore, terms such as "horizontal," "vertical," and "overhanging" do not necessarily imply that a component must be absolutely horizontal or overhanging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but rather that it can be slightly tilted.
[0034] It should also be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.
