Technical Field

[0001] The present invention belongs to the technical field of wastewater treatment, and particularly relates to a wastewater treatment device for mine exploitation. Background Art

[0002] After the mined ore is crushed, it needs to be washed to remove debris, dust and other sundries. Ordinary washing consumes a large amount of clean water and generates a large amount of wastewater at the same time; when the existing washing equipment washes the ore, it cannot recycle the water, which not only increases the water use cost but also causes more serious environmental pollution.

[0003] Therefore, as disclosed in a cleaning component for mine ore in CN220559896U, the water after cleaning is filtered and recycled during use; it can be known that the cleaning wastewater will contain soil, gravel, floating objects floating on the water surface, etc.; among them, the soil will dissolve in the water body; when a filter component with good filtering effect is selected, the cost during the use of the filter component will be high; when a filter component with poor filtering effect is selected, it cannot filter fine particles such as soil dissolved in the water body.

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0027] In the description of the present invention, it should be understood that terms such as "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery", etc. indicating orientation or positional relationships are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0028] Please refer to Figure 1 As shown, the present invention is a wastewater treatment device for mining, including a square pool body 1. A partition wall A2 and a partition wall B3 are built in the pool body 1. Three partition walls C4 are built between the partition wall A2 and the partition wall B3. Then, during use, a floating matter removal chamber, a cleaning and treatment chamber, and four static separation chambers are separated through the settings of the partition wall A2, the partition wall B3, and the partition wall C4 in the pool body 1; and the static separation chambers are located between the floating matter removal chamber and the cleaning and treatment chamber.

[0029] During use, as Figure 1 , in order to conveniently control the wastewater to flow into the static separation chamber after entering the floating matter removal chamber and control the wastewater to flow into the cleaning and treatment chamber after static separation in the static separation chamber, at this time, the water pump A arranged in the cleaning and treatment chamber is used to pump out the treated wastewater for recycling and used as water for ore cleaning; therefore, a drain port A20 is opened on the partition wall A2 at one end of the static separation chamber, and a gate A21 is arranged in cooperation with the drain port A20; a drain port B is opened on the partition wall B3 at the other end of the static separation chamber, and a gate B31 is arranged in cooperation with the drain port B.

[0030] Based on the above, during use, the wastewater for ore cleaning is injected into the floating matter removal chamber, and then several gates A21 are opened in sequence to inject the wastewater into the corresponding static separation chambers. The wastewater is statically treated in the static separation chambers to achieve solid-liquid separation; the gate B31 is opened to control the wastewater in the static separation chamber to be discharged into the cleaning and treatment chamber, and is pumped out by the water pump A for recycling.

[0031] It can be known that during use, in order to prevent impurities such as ore floating matters from entering the static separation chamber through the drain port A20 when the gate A21 is in an open state along with the water flow; as Figures 2-3 , the present invention is provided with a cross plate 5 on the side of the partition wall A2 located in the floating matter removal chamber. One side of the cross plate 5 is connected to a side plate 51, and both side surfaces of the side plate 51 protrude from the upper and lower surfaces of the cross plate 5 respectively; and the drain port A20 is located below the cross plate 5; then during use, the side plate 51 protrudes from the lower surface of the cross plate 5, and at the same time, it is controlled that the wastewater is discharged into the floating matter removal chamber directly above the cross plate 5 during use.

[0032] With long-term use, the amount of floating objects in the floating object removal chamber will increase. Therefore, in order to facilitate the cleaning of floating objects in the floating object removal chamber, a plurality of insertion holes 52 are provided on the upper end surface of the side plate 51. A plug rod 60 is inserted into the insertion hole 52 in a sliding manner. The end of the plug rod 60 is connected to a gate plate 6 that moves up and down. A floating object salvaging mechanism is provided in the floating object removal chamber located above the horizontal plate 5. Figure 6 The floating object salvaging mechanism includes a beam 7 that can float on the water surface, and also includes a driving mechanism that drives the beam 7 to move horizontally along a direction perpendicular to its length; the driving mechanism includes two traction ropes 73 respectively connected to both sides of the beam 7; and when it is necessary to clean up the floating objects during use, the gate plate 6 is first controlled to fall, and then the traction rope 73 is used to drive the beam 7 to move to one side of the pool body 1, so that the floating objects are gathered to one side of the pool body 1, and then they can be salvaged using a salvage net.

[0033] When using, Figures 5-7 In order to ensure that the cross beam 7 can move up and down with the rise and fall of the liquid level, and to control its movement above the liquid level in a direction perpendicular to itself under the action of the traction rope 73, the present invention provides guide rails 70 along the length direction of the partition wall A2 on the side panels 51 located at both ends of the cross beam 7 and the opposite side walls of the partition wall A2, and the guide rails 70 are provided with guide sliders 701 sliding along the length direction thereof; telescopic vertical rods 72 are respectively provided at both ends of the cross beam 7, and the ends of the telescopic vertical rods 72 are connected to the top side of the guide slider 701; and convex columns 100 for fixing the traction rope 73 are provided on the end surfaces of the pool body 1 located at both ends of the floating object removal chamber.

[0034] In order to facilitate the control of the lifting and lowering of the gate plate 6 during use, and it will be found during use that due to the large overall size of the pool body 1, when the gate plate 6 is set as a whole, its overall width is large, which is not convenient for actual production during use. Therefore, the number of gate plates 6 in the present invention is set to be multiple, and a cavity 61 is set in the gate plate 6, and the cavities 61 of two adjacent gate plates 6 are connected by a hose 63; a water storage tank 7 is set in the floating object removal cavity, and the water storage tank 7 is connected to a cavity 61 through a pipe A71 provided with a valve A, and the water storage tank 7 is also connected to a cavity 61 through a pipe B72 provided with a valve B, and one end of the pipe B72 is connected to a water pump B set in the water storage tank 7; through the above-mentioned arrangement, when the water in the water storage tank 7 is injected into the gate plate 6 by the water pump B during use, it can drive the gate plate 6 to move downward; on the contrary, when the water in the gate plate 6 is discharged into the water storage tank 7, the gate plate 6 is controlled to move upward.

[0035] like Figures 4-5, to facilitate the control of the up and down movement of the gate 6 and avoid a large height difference caused by the up and down movement of two adjacent gates 6, grooves 64 and limit blocks 62 that cooperate with each other are provided at both ends of the gate 6. The number of limit blocks 62 is two, and both limit blocks 62 are inserted into the grooves 64; T-shaped frames 65 and limit frames 66 that cooperate with each other are respectively provided at both ends of the gate 6; the limit frame 66 is a "[-]" shaped structure, and the limit frame 66 and the gate 6 cooperate to form a rectangular through-hole, and the T-shaped frame 65 passes through the rectangular through-hole; the T-shaped frame 65 includes a fixed rod that passes through the rectangular through-hole and has its end fixed to the gate 6, and a limit rod with a length greater than the length of the rectangular through-hole is connected to the end of the fixed rod.

[0036] In order to achieve intelligent control and selectively open the gate B31 and the gate A21 during use, a liquid level sensor A, a liquid level sensor B, and a liquid level sensor C are respectively provided in the floating object removal chamber, the cleaning and treatment chamber, and the static separation chamber; the liquid level sensor A, the liquid level sensor B, and the liquid level sensor C are connected to a controller, and the controller is connected to a water pump A and a water pump B; both the gate B31 and the gate A21 are electric gates, and both the gate B31 and the gate A21 are connected to the controller.

[0037] When it is realized, when the liquid level in the floating object removal chamber reaches the preset value, at this time, the corresponding gate A21 in the first static separation chamber is opened to control the water to flow into the corresponding static separation chamber. When the liquid level in the static separation chamber reaches the preset value, at this time, the gate A21 is closed, and at the same time, the corresponding gate 21 in the second static separation chamber is controlled to open. Repeat the above operation. When the corresponding gate 21 in the fourth static separation chamber is opened, at this time, the corresponding gate B31 in the first static separation chamber is opened, and the wastewater that has been treated in the static separation chamber is discharged into the cleaning and treatment chamber; when the corresponding gate A21 in the first static separation chamber is in the open state, at this time, the corresponding gate 21 in the second separation chamber is opened.
