Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sulfur concentrate sewage treatment, in particular to a circulating water pipeline debris isolation device. Background Art
[0002] During the flotation production process of pyrite, a large amount of clean water is needed for cooling, dilution, flushing, flotation brewing, panning, etc. The water consumption is high and a large amount of acidic wastewater is produced. If it is discharged, the treatment cost is very high. Therefore, it needs to be simply purified and then returned to the mineral processing system for recycling to reduce production costs.
[0003] Due to the complex geographical structure of the mine, and the large number of trees and weeds around it, the acidic wastewater produced by production is generally transported and collected through open channels when it is recycled, which will bring in leaves, rotten wood, grass roots, foam and other debris, which are difficult to remove in the purification pool. Directly returning it to the mineral processing system for use will clog the detection instrument, affect the stability of the foam layer, reduce the quality of mineral processing flotation, etc., affecting the continuity of production and the economic benefits of the enterprise. There is no special equipment in the existing technology to treat wastewater, and the production cost is high. There are also cases where wastewater is recycled, but the impurity removal effect is not good, which affects production efficiency. Utility Model Content

[0006] The front-stage filtration structure can perform primary filtration on the front end of the circulating water pump to reduce water resistance; the pipeline debris isolation device can perform secondary filtration on the debris to achieve fine filtration; this device adopts double filtration, which can not only reduce water resistance but also take away the debris, thereby achieving the purpose of purifying circulating water for reuse.
[0007] The pipeline debris isolation device comprises a debris isolation device shell, a partition is horizontally arranged inside the debris isolation device shell, and a gap is formed between one end of the partition and the side wall of the debris isolation device shell; the partition divides the internal space of the debris isolation device shell into an upper space and a lower space, and the upper space is a pipeline debris collection grid; an openable debris cleaning hole is arranged on the top of the debris isolation device shell, a debris filter net is detachably placed in the debris isolation device shell, and the debris filter net is obliquely arranged in the debris isolation device shell; the two ends of the debris filter net are respectively against a group of pairs of side walls of the debris isolation device shell, the lower end of the debris filter net is located below the water inlet of the debris isolation device shell, the upper end of the debris filter net is located above the water outlet of the debris isolation device shell, and the upper end of the debris filter net is located in the gap between the partition and the side wall of the debris isolation device shell. The openable cleaning hole can be used to regularly clean the debris inside the collection grid; the inclined debris filter faces the water inlet of the debris isolation device shell to collect the debris. As the debris continues to accumulate, the debris in front is squeezed by the debris behind and passes through the gap of the partition to enter the pipeline debris collection grid in the upper space, thereby completing the purpose of collecting debris. The debris filter can be disassembled and installed at any time for cleaning and maintenance.
[0008] The debris filter forms an angle of 135 degrees with the water flow direction of the rear-stage pipeline.

[0012] The lower end of the shell of the debris isolation device is 500 mm lower than the rear-stage pipeline.
[0013] The two ends of the shell of the debris isolation device are connected to the rear-stage pipelines on both sides by full welding.
[0014] The front-stage filtering structure is a stainless steel filter screen.
[0015] The specifications of the front-stage filtering structure are 30mm*30mm*6mm.
[0016] Compared with the prior art, the advantages of the utility model are: the device has a simple structure, is easy to manufacture, and is highly practical. It can remove particulate matter and floating matter in the circulating water after secondary filtration and graded impurity removal, providing conditions for water use in the next step of mineral processing and flotation, avoiding waste of water resources, having good impurity removal efficiency, reducing production costs, and providing guarantees for efficient and low-consumption production.
