Description

Technical Field

[0001] The invention belongs to the technical field of wastewater treatment, and in particular relates to a mine wastewater treatment device. Background Art

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or reuse. When processing metal ore, the surface of the ore will be washed, and during the discharge process of the wastewater generated by the washing, a filter will be installed on the pipeline to filter the wastewater. The filter is mostly installed at the connection of the pipeline, and a filter element is installed inside to block and collect sand and gravel.

[0003] As the filtered sand and gravel adhere to the filter element, the water permeability will decrease, resulting in the gradual blockage of the filter element when the wastewater flow remains unchanged. The pressure in the wastewater pipe system will gradually increase, and the filtering effect will gradually decrease. Therefore, the filter element needs to be manually cleaned or replaced regularly, which is time-consuming and labor-intensive, resulting in reduced wastewater treatment effect. Chinese patent application number 202310580986.3 discloses a mining wastewater filtration device, which feeds back the water pressure in the filter element based on an overpressure pop-up mechanism, and drives the filter element to be inserted into the pop-up hole through the pressure sealing plate when the water pressure in the filter element reaches the limit value, so that the bottom of the filter element is separated from the lower fixed plate to avoid clogging of the filter element. Although it can prevent the wastewater treatment pipeline from being damaged, the increase in internal pressure of the pipeline will cause filtration failure, making it difficult to continue filtering.

[0004] Improvements need to be made to address the shortcomings of existing technologies. Summary of the invention
