[0002] Metallurgy refers to a process and technology of extracting metals or metal compounds from minerals and processing metals into metal materials with certain properties by various processing methods. In the process of metallurgy, a large amount of water needs to be used. After being used in metallurgy, the water contains a large amount of chemical elements. Therefore, if the wastewater after metallurgy is directly discharged, the environment will be greatly affected and serious environmental pollution will be caused. Therefore, the metallurgical wastewater needs to be treated before being discharged. When the chemical precipitation method is used to treat rare earth metallurgical wastewater, the wastewater stirring device and the filtering device in the treatment are relatively simple, the stirring effect and the filtering effect are poor, and the wastewater discharge may not meet the standards, which may cause harm to the environment.

Through the cooperation of the rotating motor, the sliding rail, the rack, the gear, the stirrer and the like, the wastewater being treated in the stirring tank can be fully and uniformly stirred, so that the wastewater and the treatment agent can fully react, the phenomenon that the substances in the wastewater are not completely precipitated due to insufficient stirring can be avoided, the treatment effect can be ensured, and the wastewater discharge can meet the standards.

[0004] In the technical solution, the stirring is only performed by the rotation of the stirring blade, the stirring effect is not well improved, the mixing effect of the settling agent and the wastewater is not obviously improved, and the settling agent is added all at once in the treatment process, which is not conducive to the mixing of the settling agent and the wastewater, so that the effect of the wastewater treatment of the technical solution is still not ideal, the wastewater discharge may not meet the standards, and the environment is harmed.

[0014] The application also provides a hydrometallurgy wastewater treatment process, which comprises the following steps:

[0015] S1, preparation stage: injecting the wastewater to be treated into the device body, rotating the plunger, and adding the settling agent into the medicine releasing groove;

[0016] S2, treatment stage: starting the servo motor, driving the rotating column to rotate through the meshing of the main gear, the secondary gear, and the gear ring, stirring the wastewater through the rotation of the stirring blades, sliding the push block through the meshing of the functional gear and the arc-shaped gear rack, adding the settling agent automatically during stirring, and adjusting the PH value through the PH adjusting mechanism when the annular block is driven to rotate by the threaded cylinder.

[0017] S3, collection stage: after the treatment is completed, the servo motor is turned off, the settled wastewater is pumped out through the water pump, and the settled material at the bottom is taken out.

[0018] The application has the following advantages:

[0019] 1. Through the meshing of the main gear, secondary gear and gear ring, when the servo motor drives the main column to rotate, it drives the rotating column to rotate itself and also causes the rotating column to rotate around the main column. This causes the rotating column to drive the stirring blade to rotate around the rotating column and also around the main column, thus achieving a better stirring effect.

[0020] 2. With the automatic dosing mechanism, as the rotating column rotates around the main column, the meshing of the functional gear and the arc rack causes the threaded cylinder to rotate. The rotation of the threaded cylinder, through the threaded connection with the screw, causes the push block to slide. That is, for every rotation of the rotating column around the main column, the push block will slide a certain distance, adding part of the settling agent into the wastewater, thereby realizing automatic dosing without the need for manual dosing, which greatly reduces the labor intensity of wastewater treatment.

[0021] 3. By automatically adding the flocculant in multiple quantitative increments, compared to adding all the flocculant at once, the flocculant can be more thoroughly mixed with the wastewater, thereby further improving the wastewater treatment effect.

[0022] 4. As the rotating column rotates, it drives the ring block to rotate. Through the alignment of different permanent magnets with the electromagnet, the electromagnet experiences periodic magnetic attraction and repulsion, which causes the piston to reciprocate. This continuously absorbs the pH adjuster into the transfer chamber and then pumps it into the wastewater, thus achieving automatic addition of the pH adjuster to the wastewater and making the device more automated.

[0023] 5. The pH of the wastewater is sensed by a pH sensing probe, thereby adjusting the magnetic force of the electromagnet. By adjusting the magnetic force, the magnetic force between the permanent magnet and the electromagnet is adjusted, which in turn adjusts the stroke of the piston. The amount of pH adjuster added is adjusted by adjusting the stroke, thereby adjusting the amount of pH adjuster added according to the pH of the wastewater to achieve automatic pH adjustment.

[0024] 6. During the dosing process, the piezoelectric ceramic and indicator light are used to make the indicator light flash after the dosing is completed, so that the operator can clearly see the dosing status and observe the changes in wastewater in a timely manner, which is more conducive to wastewater treatment.

[0032] Reference Figures 1-6The utility model provides a kind of hydrometallurgy wastewater efficient treatment system, it includes: device main body 1, the section of device main body 1 is the concave letter shape with opening upwards;Rotary plate 2, rotary plate 2 is rotatably connected in device main body 1 by bearing;Four rotating columns 5, rotating column 5 is rotatably connected with rotary plate 2 by bearing penetration, rotating column 5 is equipped with medicine slot 10;Main column 4, main column 4 is hollow structure, main column 4 is rotatably connected with rotary plate 2 and the bottom wall of device main body 1 by bearing penetration and extends to the outside of device main body 1;Servo motor 3, servo motor 3 is fixedly connected with the lower surface of device main body 1, and one end of main column 4 located outside device main body 1 is fixedly connected with the output shaft of servo motor 3;Four sub gears 7, four rotating columns 5 are respectively fitted with one sub gear 7;Main gear 6, main gear 6 is fitted with main column 4, and main gear 6 is engaged with sub gear 7;Gear ring 8, gear ring 8 is fixedly connected with the inner side wall of device main body 1, and gear ring 8 is engaged with sub gear 7;A plurality of stirring blades 9, main column 4, rotating column 5 are fixedly connected with a plurality of stirring blades 9;Automatic dosing mechanism is arranged in device main body 1, and it is used for automatic addition of settling agent;PH adjusting mechanism is arranged in device main body 1, and it is used for automatic adjustment of the PH of wastewater, by the engagement of main gear 6, sub gear 7 and gear ring 8, so that main column 4 rotates, rotating column 5 rotates itself at the same time, and rotating column 5 also rotates around main column 4, so that stirring blade 9 rotates around rotating column 5 at the same time, and also rotates around main column 4, so that stirring blade 9 can rotate and stir in each part of wastewater, compared with the fixed position stirring of prior art, has better stirring effect, so that the mixing degree of settling agent and wastewater can be improved, and wastewater treatment effect can be improved.

[0033] Automatic dosing mechanism includes: four push blocks 14, push block 14 is slidably connected in corresponding medicine slot 10;Four threaded barrels 12, threaded barrel 12 is rotatably connected with corresponding rotating column 5 by bearing penetration, one end of threaded barrel 12 extends into medicine slot 10, and the other end extends into device main body 1;Four screw rods 13, screw rod 13 is threadedly connected with corresponding threaded barrel 12, and one end of screw rod 13 located in medicine slot 10 is fixedly connected with the lower surface of push block 14;Four plungers 17, plunger 17 seals medicine slot 10, and plunger 17 is threadedly connected with the inner side wall of corresponding medicine slot 10;Four function gears 20, function gear 20 is hollow structure, and function gear 20 is rotatably connected with the section of threaded barrel 12 located in device main body 1 by bearing;Arcuate rack 21, arcuate rack 21 is fixedly connected with the bottom wall in device main body 1, as Figure 4As shown, the arrangement of the arc-shaped rack 21 can make the function gear 20 rotate with the rotation of the rotating column 5, and when the two are engaged, the threaded cylinder 12 is rotated; a plurality of medicine outlet pipes 11 are fixedly connected with the side wall of the rotating column 5 located in the device main body 1, and a one-way valve is arranged in the medicine outlet pipe 11, which prevents wastewater from entering the medicine tank 10 through the medicine outlet pipe 11, thereby avoiding the influence of the wastewater on the settling agent. When the rotating column 5 rotates around the main column 4, it can drive the threaded cylinder 12 to rotate, so that the function gear 20 rotates with the threaded cylinder 12 during the rotation process, and when the function gear 20 is engaged with the arc-shaped rack 21, the threaded cylinder 12 is rotated, and through the threaded connection between the threaded cylinder 12 and the screw rod 13, the screw rod 13 is driven to move upward, and the push block 14 is driven to move upward, so that the settling agent in the medicine tank 10 is added to the wastewater through the medicine outlet pipe 11, thereby making the push block 14 slide a distance during the stirring process, and part of the settling agent is added to the wastewater, thereby realizing automatic dosing without manual dosing, and greatly reducing the labor intensity of wastewater treatment.

[0034] It is worth mentioning that by automatically adding the settling agent multiple times, compared with adding all the settling agent at once, the settling agent added at once is directly sent to the stirring blade 9, and the mixing of the wastewater and the settling agent is directly stirred, which can ensure that the settling agent is more fully mixed with the wastewater, thereby further improving the wastewater treatment effect.

[0035] It should be noted that according to the engagement relationship between the gears, the rotation direction of the secondary gear 7 is the same as that of the main gear 6, and the rotation direction of the rotating plate 2 is the same as that of the main gear 6, and through the engagement of the function gear 20 and the arc-shaped rack 21, it can be known that the rotation direction of the function gear 20 is opposite to that of the secondary gear 7, so that when the rotating column 5 rotates itself, the function gear 20 and the arc-shaped rack 21 are engaged, so that the rotation direction of the threaded cylinder 12 and the rotating column 5 is opposite, so that the screw rod 13 can move under the threaded connection.

[0036] The automatic dosing mechanism further comprises: a rod 24 rotatably connected with the inner bottom wall of the function gear 20 through a bearing; a force receiving plate 25 fixedly connected with the rod 24; a torsion spring 26 fixedly connected between the force receiving plate 25 and the inner top wall and the inner bottom wall of the function gear 20; a push plate 27 fixedly connected with the sidewall of the section of the threaded cylinder 12 located in the function gear 20; an indicator lamp 29 fixedly connected with the sidewall of the device body 1; a piezoelectric ceramic 28 fixedly connected with the inner sidewall of the function gear 20 through a support, and electrically connected with the indicator lamp 29 through a wire. When the piezoelectric ceramic 28 is impacted, an electric current is generated to light up the indicator lamp 29. When the function gear 20 rotates, the push plate 27 is pushed by the force receiving plate 25 through the contact between the push plate 27 and the force receiving plate 25, so that the function gear 20 drives the threaded cylinder 12 to rotate. If there is medicament added in the dosing groove 10, the push block 14 can slide at this time, the screw rod 13 can move at this time, and the threaded cylinder 12 can be driven to rotate by the torsion spring 26 at this time. After the medicament addition is completed, the push block 14 cannot continue to move due to the arrangement of the limiting groove 15 and the limiting block 16, so that the threaded cylinder 12 cannot rotate to drive the screw rod 13 to move. At this time, the pushing force can overcome the elastic force of the torsion spring 26 to make the force receiving plate 25 rotate until they are separated. Under the elastic force of the torsion spring 26, the force receiving plate 25 is reset to impact the piezoelectric ceramic 28, so that the indicator lamp 29 is lighted up. When the medicament addition is completed, the indicator lamp 29 can be lighted up to make the indicator lamp 29 flicker, so that the operator can clearly see the addition status of the medicament, and observe the change of the wastewater in time, which is more conducive to the treatment of the wastewater.

[0037] The PH adjusting mechanism comprises: an annular groove 22 formed in the bottom wall of the device body 1; an annular block 23 rotatably connected with the inner wall of the annular groove 22 through a bearing; a transfer cavity 31 formed in the bottom wall of the device body 1, as shown in the drawing, the transfer cavity 31 is in communication with the outside, so that the sealing sliding piston 34 can move freely; a piston 34 sealingly and slidingly connected in the transfer cavity 31; an electromagnet 35 fixedly connected with the sidewall of the side of the piston 34 away from the main column 4; a plurality of permanent magnets 36 embedded in the inner ring sidewall of the annular block 23. Figure 1 Figure 6 ​As shown, the permanent magnets 36 are uniformly distributed, and the setting directions of the magnetic poles of two adjacent permanent magnets 36 are opposite, so that when the annular block 23 rotates, the electromagnet 35 is subjected to periodic magnetic attraction and repulsion; the liquid inlet hole 32 is arranged in the sidewall of the main column 4 located in the middle transfer cavity 31, and a one-way valve is arranged in the liquid inlet hole 32, which only allows the PH adjusting liquid to enter the main column 4 from the middle transfer cavity 31; the liquid outlet hole 33 is arranged in the sidewall of the main column 4 located in the device main body 1, and a one-way valve is arranged in the liquid outlet hole 33, which only allows the PH adjusting liquid to enter the device main body 1 from the main column 4, thereby avoiding the backflow of waste water through the liquid outlet hole 33 into the main column 4; the absorption pipe 38 is fixedly connected with the device main body 1, and one end of the absorption pipe 38 extends into the middle transfer cavity 31, and the other end extends to the outside of the device main body 1. The end of the absorption pipe 38 located outside the device main body 1 is connected with a device for storing PH adjusting liquid, and a one-way valve is arranged in the absorption pipe 38, which only allows the PH adjusting agent to enter the middle transfer cavity 31 from the absorption pipe 38. Through the rotation of the annular block 23, the permanent magnets 36 with different magnetic poles are opposite to the electromagnet 35, so that the permanent magnets 36 are subjected to periodically changed magnetic attraction and repulsion, and the electromagnet 35 drives the piston 34 to reciprocate, thereby continuously absorbing the PH adjusting agent into the middle transfer cavity 31 and then pumping it into the waste water, so as to realize the automatic addition of the PH adjusting agent into the waste water, and the automation degree of the device is higher.

[0038] The PH sensing probe 30 is fixedly connected with the inner sidewall of the device main body 1, and the PH sensing probe 30 is electrically connected with the electromagnet 35 through wires, and both are also connected with a PLC control circuit. The PH sensing probe 30 can sense the PH of the waste water, and adjust the magnetic force of the electromagnet 35 according to the PH of the waste water. As prior art, it will not be described here. Thus, by sensing the PH of the waste water through the PH sensing probe 30, the magnetic force of the electromagnet 35 is adjusted, and by adjusting the magnetic force, the magnetic force between the permanent magnets 36 and the electromagnet 35 is adjusted, and then the stroke of the reciprocating sliding of the piston 34 is adjusted, and by adjusting the stroke, the addition amount of the PH adjusting agent is adjusted, so as to adjust the amount of the adjusting agent according to the PH of the waste water, and realize automatic PH adjustment.

[0039] It is worth mentioning that when the PH reaches the required size, the PH sensing probe 30 makes the electromagnet 35 de-energized, and at this time the electromagnet 35 is de-energized, and its essence is the iron core, so no matter how the magnetic poles of the permanent magnets 36 are arranged, they will all generate magnetic attraction to the iron core, that is, at this time the piston 34 will not move, thereby stopping the addition of the PH adjusting agent.

[0040] Two blocking rings 37 are fixedly connected with the inner sidewall of the middle transfer cavity 31. By arranging the blocking rings 37, the stroke of the piston 34 is limited to avoid excessive sliding.

[0041] A plurality of limiting grooves 15 are formed in the inner side wall of the medicine releasing groove 10, and a limiting block 16 is slidably connected in the limiting groove 15, and the limiting block 16 is fixedly connected with the side wall of the corresponding push block 14, and the sliding stroke of the push block 14 is limited through the cooperation of the limiting block 16 and the limiting groove 15, so as to avoid excessive sliding.

[0042] It should be noted that the bearings mentioned in the present application are all sealed bearings, so as to avoid leakage at the bearing connection.

[0043] The application also provides a hydrometallurgy wastewater treatment process, comprising the following steps:

[0044] S1, preparation stage: the wastewater to be treated is injected into the device main body 1, the plunger 17 is rotated out, and the settling agent is added into the medicine releasing groove 10;

[0046] S3, collection stage: after the treatment is completed, the servo motor 3 is turned off, the settled wastewater is pumped out by the water pump, and the settled material at the bottom is taken out.

[0047] In the application, the wastewater to be treated is added into the device main body 1, and the settling agent is added into the medicine releasing groove 10, the servo motor 3 is started, the main column 4 is driven to rotate by the servo motor 3, the main gear 6, the secondary gear 7 and the gear ring 8 are engaged, so that when the main column 4 rotates, it will drive the rotating column 5 to rotate itself, and also make the rotating column 5 rotate around the main column 4, so that the stirring blade 9 rotates around the main column 4 while rotating around the rotating column 5, so that the stirring blade 9 can fully rotate and stir in each part of the wastewater, compared with the fixed position stirring of the prior art, it has better stirring effect, so as to improve the mixing degree of the settling agent and the wastewater, and improve the wastewater treatment effect.

[0048] When the rotating column 5 rotates around the main column 4, the threaded cylinder 12 is driven to rotate around the main column 4 as well, until the threaded cylinder 12 rotates to the engagement of the arc-shaped gear rack 21 of the function gear 20, so that the threaded cylinder 12 is driven to rotate by the function gear 20, i.e. the contact between the force receiving plate 25 and the push plate 27, so that the threaded cylinder 12 rotates, and through the threaded connection between the threaded cylinder 12 and the screw rod 13, the screw rod 13 moves upward, driving the push block 14 to move upward, so that the settling agent in the medicine adding groove 10 is added into the wastewater through the medicine outlet pipe 11, so that during the stirring process, the push block 14 slides a distance and adds part of the settling agent into the wastewater every time the rotating column 5 rotates one round around the main column 4.

[0049] When the medicine adding groove 10 adds medicine, the push block 14 can slide, the screw rod 13 can move, and the threaded cylinder 12 can be driven to rotate by the torsion spring 26. After the medicine adding is completed, the push block 14 cannot continue to move due to the arrangement of the limiting groove 15 and the limiting block 16, so the threaded cylinder 12 cannot rotate to drive the screw rod 13 to move, the pushing force can overcome the elastic force of the torsion spring 26 to make the force receiving plate 25 rotate until they are separated, and the force receiving plate 25 resets and hits the piezoelectric ceramic 28 under the elastic force of the torsion spring 26, so that the indicator lamp 29 is lit, i.e. when the medicine adding is completed, the indicator lamp 29 can be lit, so that the indicator lamp 29 flashes, so that the operator can know the adding status of the medicine at a glance, so as to observe the change of the wastewater in time, which is more conducive to the treatment of the wastewater.

[0050] Through the rotation of the annular block 23, the permanent magnets 36 with different magnetic poles are opposite to the electromagnet 35, so that the permanent magnets 36 are subjected to periodically changed magnetic attraction and repulsion, and the electromagnet 35 drives the piston 34 to reciprocate, constantly sucking the PH adjusting agent into the middle transfer cavity 31 and then pumping it into the wastewater, cooperating with the PH sensing probe 30 to adjust the adding amount of the PH adjusting agent through stroke adjustment, so as to automatically adjust the PH of the wastewater.
