Description

Technical Field

[0001] The utility model relates to the technical field of mining equipment, in particular to a water clarity early warning linkage device for tailings pond water purification. Background Art

[0002] Tailings ponds are important facilities for mining enterprises. During the normal production and operation of mines, tailings slurry, a by-product of mineral processing, must be continuously discharged into the tailings pond. Tailings slurry contains a large amount of water, accounting for about 60% to 70% of the tailings slurry. The solid tailings in the tailings slurry are precipitated in the tailings pond. The water part of the tailings slurry is clarified in the pond and then transported back to the mineral processing plant through the drainage point for recycling or external discharge. At present, the filtrate discharge method of the filter press in the tailings pond adopts the undercurrent type, and it is impossible to intuitively distinguish whether the filtrate is turbid. First, the delay in controlling the turbidity of the filter press return water has always been a bottleneck problem that has plagued the normal production of the filter press workshop; second, it has a great impact on the production indicators of the water purification process.

[0003] In the application number 201920684289.1, a tailings pond tail water clarification and filtration device is disclosed, which is arranged near the entrance of the return water / drainage facilities of the tailings pond, and is characterized in that it is composed of a bracket, a buoyancy tube, a hook, a hanging rod, a geotextile, and a hanging weight. The buoyancy tubes are two, and the two ends of the buoyancy tubes are connected to the mountains on both sides of the tail of the tail of the tailings pond. The bracket is installed on the two buoyancy tubes, and 2 to 6 rows of hooks are provided on the bracket. A hanging rod is installed on each row of hooks, and a geotextile is hung on the hanging rod. A hanging weight is provided at the bottom of the geotextile. However, this application can only clarify the tail water of the tailings pond, and cannot monitor whether the filtrate is turbid, and cannot monitor the water clarity warning, which brings inconvenience to use. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a tailings pond water purification water clarity early warning linkage device, which is used to solve the problem that the existing tailings pond cannot intuitively distinguish whether the filtrate is turbid.

[0006] The feed pump is arranged outside the filtrate tank and connected to its output end through a pipeline; the output end of the feed pump is interconnected with the water purification device through a pipeline.

[0007] The turbidimeter display and the alarm device are electrically connected.

[0008] The circuit of the feed pump is connected in parallel between the alarm device and the turbidimeter display circuit.

[0009] The alarm device is arranged in the external duty room.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows: By adopting the present early warning linkage device, the problem of filtrate running muddy can be discovered and solved in a timely manner. The tailings content in the water purification equipment is significantly reduced, the effect is good, the use cost is low, and the production index effect of the water purification adsorption process is significantly improved.

[0014] The present utility model will be described below with reference to the accompanying drawings.

[0015] As Figure 1 shown, a water clarity early warning linkage device for water purification in a tailings pond includes a filter press 1, a filtrate tank 2, a turbidimeter 3, a turbidimeter display 4, an alarm device 5, a feed pump 6, and a water purification device 7. The output end of the filter press 1 is connected to the input end of the filtrate tank 2 through a pipeline 8; the output end of the filtrate tank 2 is connected to the input end of the water purification device 7 through a pipeline 8, and a feed pump 6 is arranged between the connecting pipelines 8 of the two; the turbidimeter 3 is arranged in the filtrate tank 2 and is electrically connected to the turbidimeter display 4 outside the filtrate tank 2; the feed pump 6 is arranged outside the filtrate tank 2 and is connected to its output end through a pipeline 8; the output end of the feed pump 6 is interconnected with the water purification device 7 through a pipeline 8; the circuit of the feed pump 6 is connected in parallel between the alarm device 5 and the turbidimeter display 4 circuit; here, the feed pump 6 can be controlled for pumping according to the set value set by the turbidimeter 3; the alarm device 5 is arranged in the external duty room 9; the turbidimeter 3 display 4 and the alarm device 5 are electrically connected; here, the alarm device 5 is used to detect and remind whether the set value detected by the turbidimeter 3 exceeds the standard. If it exceeds the standard, an alarm will be issued to remind the on-duty personnel to handle it.

[0016] As Figure 2As shown in the figure, when the utility model is in use, first, the tailings slurry is injected into the filter press 1 to extract the solids in the tailings slurry, realizing solid-liquid separation. The liquid filtrate flows into the filtrate tank 2 through the pipeline 8. At this time, the turbidimeter 3 and the turbidimeter display 4 are turned on to make them work, and a set value of 200 PTU (turbidity unit) is set on the turbidimeter display 4. If the turbidimeter 3 detects that it does not exceed the set value of 200 PTU (turbidity unit), the feed pump 6 operates normally and pumps the filtered filtrate in the filtrate tank 2 through the pipeline 8 to the water purification device 7 to complete the filtration and purification work. When the turbidimeter 3 detects that it exceeds the set value of 200 PTU (turbidity unit), it can be determined that the filtrate of the filter press 1 has the phenomenon of muddy leakage. The water purification feed pump 6 under linkage control stops working, and at the same time, the alarm device 5 issues an alarm to remind the on-duty personnel to handle it. Therefore, the utility model can timely discover and solve the problem of muddy leakage of the filtrate, significantly reduce the tailing sand content in the water purification equipment, with good effects, low use cost, and significantly improve the production index effect of the water purification adsorption process, bringing benefits to the enterprise.

[0017] The above is only the preferred embodiment of the utility model, and it is not intended to limit the utility model in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the utility model, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the utility model still belong to the protection scope of the technical solution of the utility model.
