Description

Technical Field

[0001] This utility model relates to the technical field of mineral processing wastewater treatment equipment, specifically to a non-ferrous metal mineral processing wastewater impurity removal and filtration device. Background Technology

[0002] The non-ferrous metal beneficiation process generates large amounts of wastewater containing pollutants through crushing, grinding, and flotation. This wastewater is characterized by high pollutant concentrations, complex types, and strong acidity / alkalinity. It contains significant amounts of heavy metal ions, non-metallic ions, organic matter, suspended solids, and colloidal particles. Direct discharge or improper treatment can cause serious environmental pollution, threatening aquatic ecosystems and human health. Therefore, with increasing environmental awareness and regulatory requirements, the research and application of wastewater removal and filtration devices for non-ferrous metal beneficiation are growing.

[0003] In the relevant technologies, non-ferrous metal ore beneficiation wastewater treatment equipment typically uses a filter screen to precipitate and filter the metal impurities in the wastewater, achieving solid-liquid separation between the precipitate and the coarse filtrate. The coarse filtrate then flows through an overflow trough into the next process for further treatment. When cleaning the sediment at the bottom of the settling tank, a sludge mixer is usually used to stir the sediment, which is then pumped out by a sludge pump to clean the sediment.

[0004] To facilitate the cleaning of deposits on the inner wall of sedimentation tanks, most sludge mixers have a brush plate installed on the mixing plate. The rotation of the mixer drives the brush head on the brush plate to clean the inner wall of the sedimentation tank. However, most brush plates are welded to the mixing plate, which is inconvenient for subsequent maintenance and cleaning. To solve the above problems, a non-ferrous metal ore beneficiation wastewater impurity removal and filtration device is proposed. Utility Model Content

[0005] In view of this, the present invention provides a non-ferrous metal ore beneficiation wastewater impurity removal and filtration device. The present invention allows the horizontal plate to be removed by disassembling two positioning bolts on the horizontal plate, thereby separating the clamping plate from the positioning block, and taking out the brush head installed on the vertical plate. The brush head can be taken out through the sealed window for cleaning or replacement. After cleaning, the brush head can be reinstalled on the positioning block in the same way, thus facilitating the subsequent maintenance and cleaning of the brush head.

Figure 1-6 The technical solutions of the embodiments of this utility model are clearly and completely described below. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0026] like Figure 1-6As shown: This embodiment provides a non-ferrous metal ore beneficiation wastewater removal and filtration device, including a sedimentation tank 101 located at the bottom of a coarse filter overflow tank 100. The sedimentation tank 101 is connected to the coarse filter overflow tank 100 via a connecting pipe, allowing the supernatant to overflow to the next process and the precipitate to enter the sedimentation tank 101. A sewage discharge pipe 102 is inclinedly located on one side of the bottom of the sedimentation tank 101, which is used to connect to a sludge pump to discharge the precipitate from the sedimentation tank 101. A stirring motor 103 is located at the bottom of the sedimentation tank 101, which drives a rotating roller 104 to rotate. A rotating roller 104 is vertically installed in the middle of the sedimentation tank 101, which drives a first connecting member 200 and a second connecting member 400 to rotate and move. Several first connecting members 200 are provided on the upper outer surface of the rotating roller 104, which connect a brush head 303 to the rotating roller 104, thereby driving the brush head 303 to rotate and move within the sedimentation tank 101.

This causes the stirring plate 203 on the first connecting member 200 to rotate the positioning block 300, which in turn causes the clamping plate 302 mounted on the positioning block 300 to rotate. This, in turn, causes the brush head 303 mounted on the clamping plate 302 to rotate and clean the inner wall of the sedimentation tank 101. The stirring rod 402 on the second connecting member 400 drives the cutting... The rotating plate 403 is used to cut the sediment at the bottom of the sedimentation tank 101, so that the sludge pump can better extract the sediment. When it is necessary to clean the brush head 303, open the opening and closing door plate 106 on the sealing window 105, remove the two positioning bolts 307 on the horizontal plate 305, pull out the horizontal plate 305, and then separate the buckle 308 connected to the horizontal plate 305 from the slot 301. The vertical plate 304 connected to the horizontal plate 305 is separated from the positioning block 300, and then the brush head 303 fixed on the vertical plate 304 can be taken out through the sealing window 105 for cleaning or replacement.
