TECHNICAL FIELD
[0001] The utility model relates to the technical field of tailing treatment equipment in mining industry, and particularly relates to a tailing dam building equipment. BACKGROUND
[0002] Tailing is the waste residue discharged by the ore dressing plant after the useful mineral components of the ore are selected under the existing technical conditions, and usually exists in the form of solid-liquid mixed slurry. With the gradual improvement of the ore dressing technical level and recovery rate, the coarse sand in the tailing is comprehensively applied, and the tail sand particle size in the tailing is getting finer and finer. At present, the solid-liquid separation and dam building method of fine particle tailing mainly has the following two kinds: one is to discharge the fine particle tailing slurry into a tailing dam for sedimentation, and the water and solid particles are gradually separated in the tailing dam by using the natural sedimentation method, the solid particles are deposited to the bottom of the pool to build a dam body, and the upper layer is mainly clear water. With the continuous inflow of the tailing slurry, the clear water overflows to the downstream storage pool through the water permeable primary dam, and is pumped or flows back to the ore dressing plant for continuous recovery and use. The tailing accumulation dam built by using the stacking method often encounters many problems such as dam building difficulty, particularly gentle deposition beach slope, dam body difficult to reach the design height and slope, poor dam body seepage, poor stability and the like. In the case of extreme weather and earthquake, the dam is prone to collapse, causing significant economic loss; the other is that the fine particle tailing slurry is treated by a filter or a pressure filter after being pre-watered by a thickener, the filtrate of the filter or the pressure filter is returned to the thickener, and the filter cake is transported to a tailing stacking yard for dry stacking treatment by using a car or a transport belt. The method can effectively improve the strength of the tailing accumulation dam, but the tailing solid-liquid separation cost and filter cake transportation cost are high, the operation efficiency is low, and the overall economic benefit of the mining enterprise is reduced.
[0003] At the present stage, when the cyclone overflow pipe is conveying tailing, the cyclone overflow pipe is connected with the overflow tank, and when the overflow tank cannot timely discharge overflow water, the cyclone overflow pipe is prone to be blocked, thereby affecting the normal operation of the cyclone, and thereby seriously affecting the dam construction progress.

[0030] The specific implementation of the utility model will be further described below in combination with the drawings.
[0031] As shown in Figure 1 and Figure 2 , a tailings dam building equipment is mainly used for tailings dam construction, which can deliver tailings slurry into the cyclone 1, under the action of the cyclone 1, the lighter particles can move upward and be discharged through the discharge pipe 302, while the heavier particles are thrown to the wall under the action of centrifugal force and move downward, and enter the sand settling tank 4 through the lower port of the cyclone 1.
[0032] In this embodiment, the tailings damming equipment comprises a plurality of screening assemblies arranged on the dam surface and spaced along the extending direction of the dam surface. The arrangement of the screening assemblies enables the tailings slurry to be screened, with coarse particles being stacked in front of the dam and fine particles being stacked in the dam 300 meters away from the dam, so as to ensure the permeability of the dam.
[0033] One end of the main pipeline 2 is connected with a pipeline pressurizing device, so that pressure can be applied to the main pipeline 2. The structure and principle of the pressurizing device are known in the art and will not be described in detail here. The pressurizing device pressurizes the main pipeline 2, avoids the blocking phenomenon, and also avoids the freezing of the overflow tank in winter.
[0034] As shown in Figure 1 each group of screening assemblies comprises a main pipeline 2, a feed pipe 301 arranged in communication with the main pipeline 2, a cyclone 1 arranged in communication with the feed pipe 301, and a discharge pipe 302 arranged in communication with the top of the cyclone 1. Under the action of the pressurizing device, the tailings slurry flows in the main pipeline 2, and the discharge pipe 302 is arranged in communication with the main pipeline 2. The feed pipe 301 is arranged in communication with the feed inlet of the cyclone 1. The top of the cyclone 1 is provided with an overflow port, and the feed pipe 301 is located below the overflow port. The discharge pipe 302 is connected to the overflow port of the cyclone 1.

A sand settling tank 4 is arranged below the cyclone 1, and the cyclone 1 is in communication with the sand settling tank 4 through the sand outlet. The tailings slurry flowing into the cyclone 1 can be screened. The heavier particles flow into the sand settling tank 4 through the sand outlet of the cyclone 1, and the lighter particles flow to the discharge pipe 302 through the overflow port. The connection between the main pipeline 2 and the feed pipe 301 forms a first connection node. The connection between the main pipeline 2 and the discharge pipe 302 forms a second connection node. A first valve 6 is arranged between the first connection node and the second connection node. A second valve 7 is arranged on the feed pipe 301, and a third valve 8 is arranged on the discharge pipe 302. In this embodiment, when the first valve 6 is closed, the second valve 7 and the third valve 8 are in an open state. At this time, the tailings slurry flows from the main pipeline 2 into the feed pipe 301, and then flows from the feed pipe 301 into the cyclone 1. When the first valve 6 is opened, the second valve 7 and the third valve 8 are in a closed state, so that the tailings slurry can flow along the main pipeline 2 into the next group of screening assemblies, so as to dam the dam surface at different positions. The adjacent screening assemblies are connected by the main pipeline 2.

[0036] The feed pipe 301 is connected to the feed inlet of the hydrocyclone 1 through a feed branch pipe; the discharge pipe 302 is connected to the overflow outlet of the hydrocyclone 1 through a discharge branch pipe. The feed pipe 301 transports the tailings slurry into the hydrocyclone 1 through the feed branch pipe, while the overflow water in the hydrocyclone 1 is transported to the discharge pipe 302 through the discharge branch pipe.
[0037] The feed pipe 301 is L-shaped and the discharge pipe 302 is L-shaped. The discharge pipe 302 includes a first pipe section connected to the discharge branch pipe and a second pipe section connected to the main pipe 2. The discharge pipe 302 is located above the feed pipe 301. The second pipe section is a pipe section that runs from the first pipe section to the main pipe 2 and is inclined from top to bottom.
[0038] The screening components are arranged in six sets at intervals along the extension direction of the main pipeline 2, with 4 units in each set and 6 units on standby.
[0039] like Figure 2 As shown, the first valve 6, the second valve 7 and the third valve 8 are respectively equipped with connecting components. The connecting components can connect the pipes to each other, making the connection between the pipes and the valves more convenient.
[0040] Specifically, the connecting assembly includes a threaded ring 10 that is rotatably fitted on both ends of the first valve 6, the second valve 7, or the third valve 8; the end of the main pipe 2 facing the first valve 6, the end of the feed pipe 301 facing the second valve 7, and the end of the discharge pipe 302 facing the third valve 8 are all provided with threaded grooves 11 that are threaded to fit the thread of the threaded ring 10.
[0041] The threaded ring 10 includes a rotating section and a threaded section. The threaded section is a circular ring structure with threads on the inner wall. The rotating section is rotatably installed on the valve. Manually rotating the threaded ring 10 can move the pipes on both sides of the first valve 6, the second valve 7, or the third valve 8 in opposite or opposite directions. The pipes are inserted into the threaded ring 10. When the pipes abut against the valve, the rotation stops, and the connection between the pipes and the valve is considered complete.
[0042] Working principle: the main pipeline 2 is located on both sides of the first valve 6, then the threaded ring 10 is rotated, the main pipeline 2 on both sides of the first valve 6 is inserted into the threaded ring 10 on the first valve 6, and is tightened, similarly, the second valve 7 is connected with the feed pipe 301, and the third valve 8 is connected with the discharge pipe 302, after the connection is completed, the first valve 6 is closed, the second valve 7 and the third valve 8 are opened, at this time, the tailing slurry flows along the main pipeline 2 under the action of the pressurizing device, the tailing slurry flows to the feed branch pipe through the feed pipe 301 and the second valve 7, the tailing slurry is transported into the cyclone 1 through the feed branch pipe, under the action of the cyclone 1, the lighter particles can move upwards, are discharged through the discharge branch pipe, and the heavier particles are thrown to the wall under the action of centrifugal force and move downwards, enter the sand box 4 through the lower port of the cyclone 1, the overflow flows into the discharge pipe 302 through the discharge branch pipe, and the overflow in the discharge pipe 302 flows into the main pipeline 2 through the third valve 8.
[0043] When the first valve 6 on one group of screening assemblies is opened, the second valve 7 and the third valve 8 are in the closed state, so that the tailing slurry can flow into the next group of screening assemblies along the main pipeline 2, so as to build the dam at different positions of the dam surface.
