Description

Technical Field

[0001] The present application relates to the technical field of sewage treatment, and in particular to a nano-magnetic powder degradation device and a sewage treatment system. Background Art

[0002] With the continuous advancement of industrialization, a large amount of sludge or wastewater containing magnetic particles generated by sewage treatment, mineral processing, metallurgy and other industries requires effective separation and recovery technology. Traditional separation generally uses magnetic separation technology, which uses the external magnetic field to separate the magnetic suspended solids in the wastewater, thereby achieving the purpose of purifying water.

[0003] However, in traditional magnetic powder degradation devices, after the magnetic roller continues to adsorb for a period of time, due to the limited adsorption area of ​​the magnetic roller, the adsorption effect of the magnetic roller will weaken as the magnetic pollutants accumulate, or even fail. To address this problem, the current traditional method is to stop the operation of the degradation device, manually remove the magnetic roller and clean it. Although the traditional treatment method can clean the magnetic roller so that it can be recycled, it will interrupt the operation of the degradation device, and there may also be a risk that the degradation effect will be greatly reduced due to untimely cleaning, which will also greatly reduce the degradation efficiency of the degradation device for pollutants and increase labor costs. Summary of the invention

[0029] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0030] In the description of this application, it should be understood that the words "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0031] See also Figures 1 to 4,,The embodiment of the present application provides a nano-magnetic powder degradation device, including a degradation tank 1, a transmission housing 2, a motor 3 and a plurality of adsorption components 4. Among them, the degradation tank 1 is used to contain the sewage to be degraded and the nano-magnetic powder. The transmission housing 2 is arranged on one side of the degradation tank 1, and a plurality of transmission rods 22 with transmission gears 21 are arranged in the transmission housing 2, and the plurality of transmission gears 21 are meshed in sequence. The motor 3 is arranged on the side of the transmission housing 2 away from the degradation tank 1, and the output shaft of the motor 3 is connected to one of the transmission rods 22 in the transmission housing 2. The plurality of adsorption components 4 are connected to the plurality of transmission rods 22 one by one and are located in the degradation tank 1. The adsorption assembly 4 includes a magnetic roller 41 and a plurality of cleaning magnetic rods 42. The magnetic roller 41 is connected to the transmission rod 22. The plurality of cleaning magnetic rods 42 are staggered and spaced along the axial direction of the magnetic roller 41. Brushes 43 are provided on the end surface of the cleaning magnetic rod 42 away from the magnetic roller 41 along its own axial direction and on one side of the cleaning magnetic rod 42 in the radial direction. In adjacent adsorption assemblies 4, the cleaning magnetic rod 42 in one adsorption assembly 4 can brush and clean the surfaces of the cleaning magnetic rod 42 and the magnetic roller 41 in another adjacent adsorption assembly 4.

[0032] The technical solution provided in the present application utilizes the degradation pool 1 to accommodate the sewage to be degraded and the nano-magnetic powder, so that the nano-magnetic powder can adsorb pollutants in the sewage to be degraded, such as heavy metals, to achieve the effect of degrading the sewage. The motor 3 is also used to drive the magnetic roller 41 and the cleaning magnetic rod 42 in the adsorption component 4 to rotate, so that the adsorption component 4 can stir the sewage to be degraded, avoid the nano-magnetic powder from settling and flowing out too quickly, improve the mixing uniformity of the nano-magnetic powder and the sewage to be degraded, improve the adsorption effect of the nano-magnetic powder, and also enable the magnetic roller 41 and the cleaning magnetic rod 42 in the adsorption component 4 to adsorb as many nano-magnetic powder clusters as possible, that is, the nano-magnetic powder after adsorbing pollutants such as heavy metals, to prepare for the subsequent recovery of the nano-magnetic powder. By arranging a brush 43 on the cleaning magnetic rod 42, in the adjacent adsorption components 4, the cleaning magnetic rod 42 in one of the adsorption components 4 can brush and clean the surface of the cleaning magnetic rod 42 and the magnetic roller 41 in another adjacent adsorption component 4, that is, when the motor 3 drives the magnetic roller 41 to rotate, it can not only improve the mixing uniformity of the nano magnetic powder and the sewage to be degraded and improve the efficiency of the nano magnetic powder adsorption, and improve the amount of nano magnetic powder agglomerates adsorbed by the magnetic roller 41 and the cleaning magnetic rod 42, but also can play the effect of collecting the nano magnetic powder agglomerates while cleaning the adsorption component 4, so that the nano magnetic powder degradation device can extend the adsorption time of the adsorption component 4 and increase the amount of adsorption without stopping work, thereby improving work efficiency. In addition, multiple adsorption components 4 realize synchronous movement through the transmission rod 22 and the transmission gear 21, so that the movement of multiple adsorption components 4 only requires one motor 3, which is conducive to simplifying the device structure and reducing the driving cost.

[0033] It should be noted that, although the technical solution of the present application still needs to separate the nano-magnetic powder group from the adsorption component 4 in the end, it is still different from not setting the adsorption component 4, directly using the stirring mechanism to stir the wastewater to be degraded, and then allowing the nano-magnetic powder to naturally settle after adsorbing heavy metals and other pollutants. The natural sedimentation method cannot guarantee that the nano-magnetic powder adsorbs pollutants fully to the greatest extent possible, that is, because of the self-gravity of the nano-magnetic powder, even if the wastewater to be degraded is in a state of stirring and rotating, the nano-magnetic powder will still accelerate the sedimentation speed as the mass of heavy metals adsorbed increases. In the present application, in addition to relying on the centrifugal force generated by stirring to improve the uniformity of the mixture of pollutants and nano-magnetic powder and the possibility of contact, the adsorption component 4 is also used to make the nano-magnetic powder and / or the nano-magnetic powder adsorbed with pollutants be adsorbed on the adsorption component 4, preventing the nano-magnetic powder that does not fully adsorb pollutants from settling to the next link. The nano magnetic powder and / or the nano magnetic powder adsorbed with pollutants will be repeatedly cycled between being adsorbed by the adsorption component 4 and being cleaned by the brush 43 until the nano magnetic powder fully adsorbs the pollutants, and the magnetic attraction of the adsorption component 4 to the nano magnetic powder that fully adsorbs the pollutants is greatly weakened, and it is unable to overcome the gravity of the nano magnetic powder that fully adsorbs the pollutants, and then the nano magnetic powder that fully adsorbs the pollutants will flow into the next link, greatly improving the utilization rate of the nano magnetic powder. Moreover, for the entire process, the present application does not need to separately set up a stirring mechanism and an adsorption mechanism, and multiple effects can be achieved through the above structure.

[0034] In some embodiments, see Figures 1 to 3 In adjacent adsorption components 4, the cleaning magnetic rods 42 in one adsorption component 4 and the cleaning magnetic rods 42 in another adsorption component 4 are alternately arranged along the axial direction of the magnetic roller 41, and the brushes 43 of the cleaning magnetic rods 42 can contact the adjacent magnetic roller 41 and the cleaning magnetic rods 42 to ensure that when the adjacent magnetic roller 41 rotates, the cleaning magnetic rods 42 of one magnetic roller 41 can clean the adjacent magnetic roller 41 and the cleaning magnetic rods 42, sweep the nano-magnetic powder off the magnetic roller 41 and the cleaning magnetic rods 42, and also avoid interference between the cleaning magnetic rods 42 between adjacent magnetic rods.

[0035] In some embodiments, see Figure 1 The nano magnetic powder degradation device also includes a magnetic powder recovery mechanism 5. The magnetic powder recovery mechanism 5 is connected to the liquid outlet of the degradation tank 1, and is used to recover the nano magnetic powder agglomerates that have adsorbed pollutants. The nano magnetic powder and / or the nano magnetic powder adsorbed with pollutants are repeatedly circulated between being adsorbed by the adsorption component 4 and being swept by the brush 43 until the nano magnetic powder fully adsorbs the pollutants, and the nano magnetic powder whose magnetic attraction to the nano magnetic powder that has fully adsorbed the pollutants is greatly weakened by the adsorption component 4 is the nano magnetic powder agglomerate. The entire recovery process does not require the work in the degradation tank 1 to be stopped, which is beneficial to improving the degradation efficiency of the nano magnetic powder degradation device.

[0036] Furthermore, the magnetic powder recovery mechanism 5 includes a recovery box 51 connected to the liquid outlet of the degradation tank 1, and a filter screen 54 is arranged in the recovery box 51, and the aperture of the filter screen 54 is smaller than the minimum width of the nano magnetic powder mass, so that the liquid and the nano magnetic powder mass flowing into the recovery box 51 from the degradation tank 1 can be separated, thereby effectively recovering the nano magnetic powder mass, and then recovering the nano magnetic powder, recycling it, and reducing the cost. It should be noted that a switch valve can be set at the liquid outlet to control the connection and disconnection between the degradation tank 1 and the recovery box 51, so as to prevent the wastewater to be degraded from flowing out of the degradation tank 1 before being degraded.

[0037] In some embodiments, see Figures 1 to 4 The magnetic powder recovery mechanism 5 also includes a motion conversion mechanism 52 and a push plate 53. The recovery box 51 is provided with a first storage chamber 511 for storing the degraded liquid and a second storage chamber 512 for storing the nano magnetic powder mass. The first storage chamber 511 and the second storage chamber 512 can be communicated. The push plate 53 and the filter screen 54 are both located in the first storage chamber 511. The motion conversion mechanism 52 is connected to the output end of the motor 3 and is used to convert the rotary motion of the output end of the motor 3 into a linear motion. The push plate 53 is arranged on the filter screen 54 and connected to the motion conversion mechanism 52, so that the linear motion converted by the motion conversion mechanism 52 can push the push plate 53 to move on the filter screen 54, and push the nano magnetic powder mass into the second storage chamber 512. By using the motion conversion mechanism 52 to convert the rotary motion of the output end of the motor 3 into linear motion, the motion conversion structure can drive the push plate 53 to move on the filter screen 54, so that the push plate 53 can push the nano magnetic powder group that falls on the filter screen 54, and push it from the first storage chamber 511 to the second storage chamber 512, so that the nano magnetic powder group is completely separated from the liquid, and it is convenient to take it out from the second storage chamber 512 for secondary use. And the power source of the motion conversion mechanism 52 is the motor 3, that is, the adsorption component 4 and the motion conversion mechanism 52 share a power source, that is, the motor 3, which is conducive to saving driving costs.

[0038] Furthermore, the output shaft sleeve of the motor 3 is provided with a first bevel gear 6 , and the motion conversion mechanism 52 includes a second bevel gear 521 , a third bevel gear 522 , a fourth bevel gear 523 , a connecting rod 524 , a driving rod 525 and a reciprocating rod 526 . The second bevel gear 521 is meshed with the first bevel gear 6, the connecting rod 524 is penetrated by the second bevel gear 521, the third bevel gear 522 is sleeved on the end of the connecting rod 524 away from the second bevel gear 521 and is located in the first storage chamber 511, the fourth bevel gear 523 is meshed with the third bevel gear 522, and the axial end surface of the fourth bevel gear 523 is provided with a driving column 527, and the driving rod 525 is connected to the fourth bevel gear 523 through the driving column 527, so that the driving rod 525 can swing with the rotation of the fourth bevel gear 523, and the end of the driving rod 525 away from the connecting rod 524 is transmission-connected with the reciprocating rod 526, and the reciprocating rod 526 is arranged on the filter screen 54 and connected to the push plate 53, so that the reciprocating rod 526 can push and pull the push plate 53 reciprocatingly under the swinging motion of the driving rod 525. The specific movement process is as follows:

[0039] The motor 3 is started, and the output shaft of the motor 3 rotates, driving the adsorption component 4 to rotate, stirring the wastewater to be degraded and cleaning the magnetic roller 41 and the cleaning magnetic rod 42 in the adsorption component 4, and at the same time, the first bevel gear 6 is driven to rotate, and the first bevel gear 6 drives the second bevel gear 521 to rotate, converting the vertical rotation of the first bevel gear 6 into horizontal rotation, so that the connecting rod 524 can vertically penetrate the second bevel gear 521, and the connecting rod 524 rotates with the second bevel gear 521, converting the original vertical rotation into horizontal rotation. The connecting rod 524 drives the third bevel gear 522 to rotate horizontally, and the third bevel gear 522 drives the fourth bevel gear 523 to rotate vertically. The driving column 527 on the fourth bevel gear 523 rotates with the fourth bevel gear 523, and then drives the driving rod 525 to swing. The driving rod 525 drives the reciprocating rod 526 to reciprocate with the swinging motion, so that the push plate 53 can be repeatedly pushed to push the nano-magnetic powder group on the filter screen 54 into the second storage chamber 512, so as to achieve safe separation of the liquid and the nano-magnetic powder group.

[0040] Furthermore, the radius of the third bevel gear 522 is smaller than the radius of the fourth bevel gear 523, so that the fourth bevel gear 523 can reduce the rotation speed, thereby reducing the reciprocating speed of the driving rod 525 and the reciprocating rod 526, extending the service life of the driving rod 525 and the reciprocating rod 526, and also increasing the amount of nano-magnetic powder clusters pushed into the second storage chamber 512 each time the push rod is pushed.

[0041] In some embodiments, see Figure 1The driving rod 525 includes a rod body 5251 and a fan-shaped toothed disc 5252. The rod body 5251 is provided with a waist-shaped groove 5253. The driving column 527 is connected to the waist-shaped groove 5253. The fan-shaped toothed disc 5252 is connected to the rod body 5251. A rotating shaft fixed in the first storage chamber 511 is penetrated at the connection between the fan-shaped toothed disc 5252 and the rod body 5251. A plurality of active teeth are provided on the side of the fan-shaped toothed disc 5252 away from the rod body 5251. A plurality of driven teeth are provided on the reciprocating rod 526. The active teeth mesh with the driven teeth. When the fourth bevel gear 523 rotates, the driving column 527 rotates with the fourth bevel gear 523 and moves along the waist-shaped groove 5253. The rod body 5251 is restricted by the rotating shaft, so that the end of the rod body 5251 can swing in an arc shape. The swing of the end of the rod body 5251 further drives the fan-shaped toothed disc 5252 to swing. The driving teeth on the sector-shaped toothed disc 5252 mesh with the driven teeth of the reciprocating rod 526 , thereby driving the reciprocating rod 526 to perform linear reciprocating motion, and then driving the push plate 53 to perform reciprocating motion in the direction toward and away from the second storage chamber 512 , pushing the nano-magnetic powder mass into the second storage chamber 512 .

[0042] For further information, see Figure 1 The motion conversion mechanism 52 further includes at least two limiting rods 528, which penetrate the filter screen 54 and are arranged in the first storage chamber 511 at intervals. The limiting rods 528 are provided with limiting holes, and the limiting holes of at least two limiting rods 528 are coaxially arranged. The reciprocating rod 526 passes through at least two limiting holes in sequence and is connected to the push plate 53. By limiting the movement of the reciprocating rod 526 by using the limiting rod 528, it is ensured that the reciprocating rod 526 can stably move toward or away from the second storage chamber 512, and the reciprocating rod 526 is prevented from moving away.

[0043] In some embodiments, a partition 55 is provided in the recycling box 51, and the first storage chamber 511 and the second storage chamber 512 are separated by the partition 55. A door 56 is rotatably connected to the partition 55. The door 56 is located on the moving path of the push plate 53, and can push the door 56 to connect the first storage chamber 511 with the second storage chamber 512. By setting the partition 55, the first storage chamber 511 and the second storage chamber 512 are separated to prevent the degraded sewage from flowing into the second storage chamber 512, causing the degraded sewage to mix with the nano magnetic powder group, which is not conducive to the subsequent recycling of the nano magnetic powder group. In addition, by rotating the door 56 on the partition 55, the push plate 53 can push the door 56 to connect the first storage chamber 511 with the second storage chamber 512, and then push the nano magnetic powder group into the second storage chamber 512. After the push plate 53 is away from the door 56, the door 56 can be automatically closed by its own gravity, which can prevent the sewage from flowing into the second storage chamber 512 and separate the sewage and the nano magnetic powder group.

[0044] The embodiment of the present application also provides a sewage treatment system, including the nano magnetic powder degradation device as described in any of the above embodiments. Since the sewage treatment system includes the nano magnetic powder degradation device, the sewage treatment system has the same structure and beneficial effects as the nano magnetic powder degradation device, which will not be repeated here.
