Description

Technical Field

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

[0002] Mine wastewater is a general term for various wastewaters generated during mining, including natural leached water, mineral processing wastewater, overflow water from tailings dams and slag dumps, etc. The main sources of mine wastewater include underground infiltration drainage, and wastewater containing a large amount of suspended matter and harmful elements produced by the contact reaction between groundwater and coal and rock formations due to the increasing depth of mine excavation during coal mining operations. Mine wastewater contains a large amount of inorganic suspended matter and suspended particles (such as coal powder), some metal ions and sulfides, etc., with uniform water and a large amount of water. The treatment of mine wastewater is of great significance for protecting the environment and saving resources. Through reasonable treatment processes and measures, the pollution of mine wastewater to the environment can be effectively reduced, and at the same time, the recycling of resources can be achieved.

[0003] The existing treatment system for mine wastewater, if the mine wastewater is to be recycled, needs to be deeply treated to reduce the small particle impurities in the wastewater, reduce the organic matter and suspended solids in the wastewater, maintain the safety of the wastewater, and enable the wastewater to be safely reused. However, the existing deep treatment equipment for mine wastewater, due to the large discharge of wastewater, with the long-term implementation of wastewater treatment, the mechanism for cleaning wastewater is prone to accumulate dirt of different properties, and is easily blocked by dirt, affecting the working efficiency of the equipment. Therefore, in the process of wastewater treatment, it is also necessary to regularly transfer dirt and clean the treatment equipment. Due to the large discharge of mine wastewater, the workload consumed in transferring dirt is large, the efficiency is reduced, and in the process of cleaning dirt, the wastewater treatment work needs to be suspended, which reduces the efficiency of wastewater treatment. Therefore, the present application provides a deep treatment system for mine wastewater to meet the demand. Summary of the invention

[0012] Furthermore, the cleaning structure includes a plurality of first cleaning scrapers and second cleaning scrapers equidistantly distributed along a circular trajectory, the second cleaning scraper and the first cleaning scraper are respectively located in front and rear sides of the impurity removal filter, and the second cleaning scraper and the first cleaning scraper are respectively arranged on two connecting rings, and when the two connecting rings rotate, the two groups of first cleaning scrapers and second cleaning scrapers rotate synchronously.

[0013] Furthermore, the activated carbon adsorption filter layers are arranged equidistantly along a circular trajectory, and a stabilizing frame is provided on each of the activated carbon adsorption filter layers.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Example 1: Reference Figure 1-7 A mine wastewater deep treatment system shown in the figure includes an inclined guide frame 1, the wastewater is located inside the guide frame 1 and flows along an inclined path, a rotatable impurity removal filter 2 is provided inside the guide frame 1, and a plurality of activated carbon adsorption filter layers 10 that can rotate synchronously and in the opposite direction with the impurity removal filter 2 are provided behind the impurity removal filter 2, and the impurity removal filter 2 and the activated carbon adsorption filter layer 10 distributed from top to bottom receive impurities in the sewage flowing into the guide frame 1. The impurity removal filter 2 can filter small particles of impurities in the wastewater and reduce pollutants in the wastewater. The activated carbon adsorption filter layer 10 has a high pore structure and surface area, and can adsorb organic matter in the sewage, such as grease, suspended matter and organic dissolved matter, so that the wastewater can be recycled.

[0033] Due to the large discharge volume of mine wastewater, in order to enable the impurity removal filter 2 to filter impurities in the sewage for a long time and efficiently, three limit plates 21 arranged equidistantly along the circumferential trajectory are provided on the side of the impurity removal filter 2 facing the water inlet end of the guide frame 1. The three limit plates 21 divide the impurity removal filter 2 into fan-shaped accommodation spaces of equal area. With the continuous implementation of the wastewater treatment work, when a certain amount of dirt is accumulated in the fan-shaped accommodation workpiece located at the bottom of the front side of the impurity removal filter 2, the impurity removal filter 2 can be controlled to rotate so that the multiple fan-shaped accommodation spaces located on the surface of the impurity removal filter 2 switch positions one after another. The fan-shaped accommodation space with accumulated dirt can be rotated upward and separated from the original position to facilitate the staff to clean the dirt in the accommodation space. The fan-shaped accommodation space in an empty state can be moved to fill the position, facing the flow direction of the wastewater, receiving the flowing wastewater again, and implementing the wastewater cleaning operation.

[0034] At the same time, when the impurity removal filter 2 moves, multiple activated carbon adsorption filter layers 10 rotate synchronously with it, so that the activated carbon adsorption filter layer 10 in contact with the flowing wastewater always has a good adsorption effect, ensuring the efficient adsorption capacity of the activated carbon adsorption filter layer 10.

[0035] As the impurity removal filter 2 and the activated carbon adsorption filter layer 10 rotate, without affecting the normal implementation of the wastewater cleaning work, the staff can also perform cleaning operations on the fan-shaped accommodating space and the activated carbon adsorption filter layer 10 exposed above the guide frame 1, thereby improving the treatment efficiency of the entire mine wastewater deep treatment system.

[0036] As the wastewater treatment work continues, cleaning structures that rotate synchronously with the activated carbon adsorption filter layer 10 are respectively provided in front and rear of the impurity removal filter 2. When multiple activated carbon adsorption filter layers 10 switch positions successively, the cleaning structure can transfer the dirt accumulated on the inner wall of the guide frame 1. The cleanliness inside the guide frame 1 is improved, the workload required for manual cleaning of the guide frame 1 is reduced, and it has the advantage of self-cleaning.

[0037] Example 2: Figure 3-9 As shown, on the basis of Example 1, in order to facilitate the staff to handle the impurities inside the fan-shaped accommodating space, the end of the limit plate 21 facing the edge of the impurity removal filter 2 is connected by an interception ring 22, and the inner sides of the two adjacent limit plates 21 are provided with a first guide plate 23 and a second guide plate 24 that can be opened and closed. When the fan-shaped accommodating space with dirt accumulated inside is transferred to the top of the guide frame 1, the first guide plate 23 and the second guide plate 24 in the fan-shaped accommodating space can be controlled to make a closing movement, so that the impurities in the space can be gathered in the relative space between the first guide plate 23 and the second guide plate 24.

[0038] Specifically, the first guide plate 23 and the second guide plate 24 are respectively provided with a linkage gear 1 25 and a linkage gear 2 26 at one end close to the central axis of the impurity removal filter 2, and the linkage gear 1 25 and the linkage gear 2 26 are both provided on the impurity removal filter 2 through a rotating shaft, and the linkage gear 1 25 is meshed and connected with the linkage gear 2 26, and a plurality of power motors 1 27 that can drive the linkage gear 2 26 to rotate are provided at the rear of the impurity removal filter 2. The operation of the power motor 1 27 can provide power for the linkage gear 2 26.

[0039] Under the meshing force of the linkage gear 2 26 and the linkage gear 1 25, when the linkage gear 1 25 and the linkage gear 2 26 rotate synchronously and in opposite directions, the first guide plate 23 and the second guide plate 24 can be located in the fan-shaped accommodation space to perform a closing movement until the dirt in the fan-shaped accommodation space is accumulated. The accumulated dirt is convenient for the staff to clean in a centralized manner, which reduces the time required in the process of transferring the dirt, reduces the workload required for cleaning the fan-shaped accommodation space with a large volume, and improves the cleaning efficiency.

[0040] Example 3: Figure 3-10 As shown, on the basis of Example 1 and Example 2, in order to make the impurity removing filter screen 2 rotate smoothly, a linkage shaft 3 that can drive the impurity removing filter screen 2 to rotate is provided at the central axis position of the impurity removing filter screen 2, and the linkage shaft 3 is installed on the guide frame 1 through a bearing seat, and both ends of the linkage shaft 3 exposed to the outside of the guide frame 1 are provided with linkage gear plates 31 coaxially distributed therewith, and one side of the linkage gear plate 31 is provided with a driving gear plate 1 32 meshing therewith, and the driving gear plate 1 32 is connected to a driving gear plate 2 33 arranged parallel to the driving gear plate 1 through a driving shaft 34, and the driving gear plate 2 33 and the driving gear plate 1 32 are respectively located on the inner and outer sides of the guide frame 1.

[0041] Two driving shafts 34 are installed on the guide frame 1 through a bearing seat, and a power motor 2 35 is provided below the guide frame 1 to control the rotation of the driving shaft 34 located below. The power motor 2 35 can provide power for the driving shaft 34. Under the meshing force of the driving gear disc 1 32 and the linkage gear disc 31, when the driving gear disc 1 32 and the linkage gear disc 31 rotate synchronously and in the opposite direction, the linkage shaft 3 and the impurity removal filter 2 rotate synchronously.

[0042] Furthermore, the driving gear disc 1 33 is meshedly connected with a gear ring frame 4 coaxially distributed with the impurity removal filter 2, and an extension ring 5 is provided outside the gear ring frame 4. The extension ring 5 is arranged on the inner wall of the guide frame 1, and a connecting ring 6 is provided on the extension ring 5. The two connecting rings 6 are located on the inner side of the guide frame 1 and are distributed from top to bottom. When the driving gear disc 1 32 and the driving gear disc 2 33 rotate synchronously, the two sets of gear ring frames 4, the extension ring 5 and the connecting ring 6 rotate in the direction opposite to the impurity removal filter 2.

[0043] The cleaning structure includes a plurality of first cleaning scrapers 7 and second cleaning scrapers 8 equidistantly distributed along a circular track, the second cleaning scrapers 8 and the first cleaning scrapers 7 are respectively located in front of and behind the impurity removal filter 2, and the second cleaning scrapers 8 and the first cleaning scrapers 7 are respectively arranged on two connecting rings 6. When the two connecting rings 6 rotate, the two groups of first cleaning scrapers 7 and second cleaning scrapers 8 rotate synchronously. During the rotation process, the first cleaning scrapers 7 and the second cleaning scrapers 8 can scrape off the dirt adhering to the inner wall of the guide frame 1, thereby improving the cleanliness of the guide frame 1.

[0044] At the same time, since the activated carbon adsorption filter layers 10 in the present application document are arranged equidistantly along a circular trajectory, and a stabilizing frame 9 is provided on each of the activated carbon adsorption filter layers 10, in order to enable the activated carbon adsorption filter layers 10 to rotate synchronously with the cleaning structure, the ends of the two adjacent first cleaning scrapers 7 away from the inner wall of the guide frame 1 are connected to the stabilizing frame 9. Therefore, when the first cleaning scraper 7 in the cleaning structure rotates, multiple activated carbon adsorption filter layers 10 rotate synchronously.

[0045] Since the impurity removal filter 2 rotates in opposite directions to the cleaning unit and the activated carbon adsorption filter layer 10, the cleaning operations of the impurity removal filter 2 and the activated carbon adsorption filter layer 10 can be carried out on both sides of the guide frame 1 respectively. The cleaning operation of the first cleaning scraper 7 and the second cleaning scraper 8 can also be carried out on the side where the cleaning operation is carried out on the activated carbon adsorption filter layer 10, thereby reducing interference during the cleaning operation and facilitating the centralized transfer of dirt.

[0046] It is worth mentioning that in the present application document, in order to allow the waste water to flow smoothly, a water inlet 11 and a water outlet 12 distributed from top to bottom are provided on the guide frame 1. Since the cleaning range of the first cleaning scraper 7 and the second cleaning scraper 8 is limited, and the gear ring frame 4, the extension ring 5 and the connecting ring 6 are all located inside the guide frame 1, in order to reduce the cleaning dead angle, two partitions 13 distributed from top to bottom are provided in the inner cavity of the guide frame 1. The gear ring frame 4, the extension ring 5 and the connecting ring 6 are all located on the inner side of the gap formed by the partition 13 and the guide frame 1. The water inlet 11 extends to the bottom of the partition 13 distributed above, which can effectively prevent the waste water from polluting the gear ring frame 4, the extension ring 5 and the connecting ring 6.

[0047] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
