Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of wastewater treatment, and particularly relates to a mine wastewater treatment device. BACKGROUND

[0002] Wastewater treatment is a process of purifying wastewater to meet the water quality requirements for discharge into a certain water body or reuse. When metal ores are processed, the ore surface is washed, and the wastewater generated during discharge is filtered by a filter arranged on the pipeline. The filter is usually arranged at the connection of the pipeline, and a filter core is arranged inside to block and collect sand and stones.

[0003] As the filter core is attached with sand and stones during filtration, the water passing property is reduced, the pressure in the wastewater pipeline system gradually increases, and the filtration effect gradually decreases under the condition that the wastewater flow remains unchanged. Therefore, the filter core needs to be cleaned manually or replaced regularly, which is time-consuming and labor-intensive, reduces the wastewater treatment effect, and a mine wastewater filter device disclosed in Chinese Patent No. 202310580986.3 feeds back the water pressure in the filter core based on an overpressure ejection mechanism, and when the water pressure in the filter core reaches a limit value, the filter core is inserted into the ejection hole through the pressure sealing plate to separate the bottom of the filter core from the lower fixed plate, so as to prevent the filter core from being blocked. Although the pipeline for wastewater treatment can be prevented from being damaged, the filtration will fail after the pressure in the pipeline increases, and it is difficult to continuously perform the filtration work.

Detailed Implementation

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0018] like Figures 1-5 As shown, a mine wastewater treatment device includes a diversion box 1 and four wastewater treatment tanks 2. The four wastewater treatment tanks 2 are distributed around the diversion box 1, and the lower ends of the wastewater treatment tanks 2 are connected to the diversion box 1. A drive motor 3 is fixed to the rear side of the diversion box 1, and an inlet 101 is provided on the front side of the diversion box 1. Mine wastewater enters the diversion box 1 through the inlet 101. A partition 4 is provided near the upper part of the wastewater treatment tank 2, dividing the wastewater treatment tank 2 into an upper cavity 201 and a lower cavity 202. The lower cavity 202 is divided into two parts. A first drain port 203 is provided on the side wall near the upper end of the lower cavity 202, and a second drain port 204 is provided on the side wall of the upper cavity 203. A sewage discharge sleeve 5 is provided in the upper cavity 201. The lower end of the sewage discharge sleeve 5 is fixedly connected to the partition plate 4 and communicates with the lower cavity 202. Multiple through holes are evenly distributed on the side wall of the sewage discharge sleeve 5. An end cap 6 is slidably sleeved on the sewage discharge sleeve 5 to block the through holes on the side wall of the sewage discharge sleeve 5.

[0019] In this embodiment, a push-pull rod 7 is fixed to the lower side of the end cap 6, and a rocker arm 8 is provided at the lower end of the push-pull rod 7. The upper end of the rocker arm 8 is hinged to the lower end of the push-pull rod 7, and the lower end of the rocker arm 8 is inserted into the distributor box 1. A crankshaft 9 is provided in the distributor box 1, and the crankshaft 9 is fixedly connected to the output shaft of the drive motor 3. The lower end of the rocker arm 8 is sleeved on the crankshaft 9.

[0020] In this embodiment, a filter element 10 is provided in the lower cavity 202. The upper end of the filter element 10 is fixedly connected to the partition plate 4, and the lower end of the filter element 10 is fixedly connected to the lower end of the wastewater treatment tank 2. Multiple annular first baffles 11 are sleeved on the outside of the filter element 10. The gap between adjacent first baffles 11 is equal to the width of the first baffle 11. Multiple annular second baffles 12 are sleeved inside the filter element 10. The width of the second baffle 12 is equal to the width of the first baffle 11, and the distance between adjacent second baffles 12 is equal to the width of the second baffle 12.
