[0043] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0044] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0045] In each embodiment of the present application, "proximal end" and "distal end" refer to the position of each component relative to the user in the use environment, wherein the end closer to the user is designated as the "proximal end" and the end farther from the user is designated as the "distal end".

[0046] The inventive concept of the present application is described here:

[0047] As a commonly used electrochemical method in water treatment, electrocoagulation can complete oxidation, reduction, flocculation, flotation and other processes at one time. In the sewage treatment device using electrocoagulation, electrode materials are needed to treat impurities in sewage. In this process, electrode materials are used as consumables.

[0048] In the sewage treatment device in the prior art, when the electrode material is consumed to a certain extent, the electrode material needs to be polished or replaced to continue to maintain the efficient sewage treatment effect. However, in the process of polishing or replacing the electrode material, the sewage treatment device needs to be shut down, which causes a long vacuum period in the sewage treatment device, which is not conducive to the continuous treatment of sewage.

[0049] Based on this, the inventor provides a sewage treatment device, which does not need to be shut down during the process of grinding or replacing electrode sheets. That is to say, the sewage treatment device provided in the embodiment of the present application can simultaneously carry out sewage treatment, grinding or replacement of electrode sheets, thereby avoiding the vacuum period caused by grinding or replacement of electrode sheets, which is conducive to the sewage treatment device to continuously treat sewage.

[0050] The following is combined with Figures 1 to 10 , a sewage treatment device 1 provided in the present application is described in detail through specific embodiments and application scenarios.

[0051] Please also see Figure 1-Figure 4 The embodiment of the present application provides a sewage treatment device 1, including: a reaction chamber, a base shaft 20, a plurality of electrode plate assemblies 30 and a lifting and grinding mechanism 40.

[0052] The reaction chamber 10 can serve as the outer shell of the sewage treatment device 1. The interior of the reaction chamber 10 can form a first functional chamber 110 and a second functional chamber 120 that are interconnected. In the embodiment of the present application, the first functional chamber 110 can be used for sewage treatment, and the second functional chamber 120 can be arranged above the first functional chamber 110 and used to clamp the electrode plate assembly 30.

[0053] The base shaft 20 may be disposed in the first functional cavity 110 and serve as a carrier of multiple groups of electrode plate assemblies 30 .

[0054] Multiple groups of electrode plate assemblies 30 can be arranged in the first functional cavity 110 and spaced around the outer circumference of the base shaft 20. For example, in one embodiment, the electrode plate assemblies 30 can be arranged in 4 groups, 5 groups, or 6 groups. Each group of electrode plate assemblies 30 can include multiple electrode sheets 310 spaced and arranged in parallel along the axial direction of the base shaft 20. The electrode sheets 310 can be connected to the base shaft 20 and can be used for electrocoagulation operation. In this embodiment, the electrode plate assembly 30 can be detachably connected to the base shaft 20, and the electrode sheets 310 can be detachably connected to the base shaft 20.

[0055] The lifting and polishing mechanism 40 may be disposed in the reaction chamber 10 , and the lifting and polishing mechanism 40 may be switched between a first position, a second position and a third position along a vertical direction, wherein the second position is located between the first position and the third position.

[0056] Specifically, when the lifting and polishing mechanism 40 is located at the first position, the lifting and polishing mechanism 40 is disposed in the second functional cavity 120 , and the lifting and polishing mechanism 40 does not work at this time.

[0057] See also Figure 2 When the lifting and grinding mechanism 40 is in the second position, the lifting and grinding mechanism 40 at least partially extends into the gap between the electrode sheets 310 and can abut against the surface of the electrode sheet 310 to grind the surface of the electrode sheet 310.

[0058] Please also see Figure 3 and Figure 4When the lifting and grinding mechanism 40 is in the third position, the lifting and grinding mechanism 40 can unlock the electrode sheet 310 and the base shaft 20, and can clamp and fix the electrode sheet 310 to clamp the electrode sheet 310 out of the first functional cavity 110.

[0059] That is to say, in this embodiment, the lifting and grinding mechanism 40 not only has the function of grinding the electrode sheet 310 , but also has the function of taking the electrode sheet 310 out of the first functional cavity 110 , so that the user can easily replace the electrode sheet 310 .

[0060] Please also see Figure 2 and Figure 5 It should be noted that the embodiment of the present application does not limit the detachable manner between the electrode sheet 310 and the base shaft 20. For example, in one embodiment, the sewage treatment device 1 may further include an elastic buckle 320, the fixed end of the elastic buckle 320 may be connected to the base shaft 20, the electrode sheet 310 may be provided with a buckle groove 311, and the free end of the elastic member may be selectively embedded in the buckle groove 311. When the free end of the elastic member is embedded in the buckle groove 311, the electrode sheet 310 is locked with the base shaft 20. When the free end of the elastic member is located outside the buckle groove 311, the electrode sheet 310 is unlocked from the base shaft 20.

[0061] Please also see Figure 2 , Figure 4 and Figure 5 , to match it, the lifting and grinding mechanism 40 may include a lifting cylinder 410, a clamping member 420 and a triggering member 430. The lifting cylinder 410 may be arranged vertically, and the clamping member 420 and the triggering member 430 may be connected to the lifting cylinder 410, so as to facilitate the lifting and grinding mechanism 40 to switch between the aforementioned first position, the second position and the third position. The clamping member 420 may be used to abut against the electrode sheet 310 to grind the electrode sheet 310 or to clamp the electrode sheet 310 to grab the electrode sheet 310. The triggering member 430 may be used to unlock the electrode sheet 310 and the base shaft 20. Specifically, when the lifting and grinding mechanism 40 is in the third position, the triggering member 430 may open the free end of the elastic buckle 320, thereby disengaging the elastic buckle 320 from the buckle groove 311, so as to achieve the effect of unlocking the electrode sheet 310 and the base shaft 20.

[0062] For further information, please also refer to Figure 4 and Figure 6In one embodiment, the lifting and grinding mechanism 40 may further include: a support frame 440, a first rod 450, a second rod 460, a first gear 470, a driving gear 480, and a second driving member 490. The first rod 450 and the second rod 460 may be movably connected to the support frame 440, specifically, they may rotate relative to the support frame 440. The trigger member 430 may also be connected to the support frame 440. In other embodiments, a partial area of ​​the frame of the support frame 440 may be used as the trigger member 430, which may be specifically set according to actual conditions.

[0063] As mentioned above, in this embodiment, the clamping member 420 may include a first polishing sheet 421 and a second polishing sheet 422, and the first polishing sheet 421 and the second polishing sheet 422 may cooperate with each other to approach the electrode sheet 310, and then polish the electrode sheet 310 or grab the electrode sheet 310. It should be noted that the embodiment of the present application does not limit the specific positions of the first polishing sheet 421 and the second polishing sheet 422. For example, in one embodiment, the first grinding sheet 421 can be close to the electrode sheet 310, and the second grinding sheet 422 can be relatively far away from the electrode sheet 310. The first grinding sheet 421 can be threadedly connected to the first rod 450, and can be close to or away from the electrode sheet 310 under the rotation of the first rod 450. The second grinding sheet 422 can be connected to the second rod 460. When the first rod 450 rotates and drives the first grinding sheet 421 to approach the electrode sheet 310, the first grinding sheet 421 can abut against the surface of the electrode sheet 310. At this time, the first grinding sheet 421 and the second grinding sheet 422 sandwich the electrode sheet 310 in the middle, and then the surface of the electrode sheet 310 can be polished. When the first rod 450 continues to rotate and drives the first grinding sheet 421 to continue to approach the electrode sheet 310, the first grinding sheet 421 and the second grinding sheet 422 can clamp the electrode sheet 310 together, and then the electrode sheet 310 can be grabbed out of the first functional cavity 110. That is to say, in the aforementioned embodiment, the distance between the first grinding sheet 421 and the electrode sheet 310 and the abutment force can be adjusted, so that the first grinding sheet 421 and the second grinding sheet 422 cooperate to achieve the grinding or grabbing operation, and in the aforementioned embodiment, only the first grinding sheet 421 can be set as a movable structure, and the second grinding sheet 422 can be set as a fixed structure.

[0064] The first gear 470 can be connected to the first rod 450, the driving gear 480 can be meshed with the first gear 470, and the second drive can be connected to the driving gear 480 and is used to drive the driving gear 480 to rotate. When the driving gear 480 rotates, it can drive the first gear 470 to rotate, and then drive the first rod 450 to rotate, thereby realizing the operation of the first grinding plate 421 approaching or moving away from the electrode plate 310. The aforementioned structure can make the entire lifting and grinding mechanism 40 more automated.

[0065] It can be understood that, in another embodiment, the first grinding plate 421 and the second grinding plate 422 can both be set as movable structures. In this embodiment, the second grinding plate 422 can also be connected to the second rod 460, so that the first grinding plate 421 and the second grinding plate 422 can move toward the electrode plate 310 or away from the electrode plate 310 at the same time.

[0066] Furthermore, in one embodiment, the lifting and grinding mechanism 40 may also include a second gear 4110, the second gear 4110 may be connected to the second rod 460, the first gear 470 and the second gear 4110 may be meshed with each other, and the rotation directions of the first gear 470 and the second gear 4110 are opposite, that is, in this embodiment, the driving gear can drive the first grinding plate 421 and the second grinding plate 422 to move closer to or away from each other during the rotation process.

[0067] Also, please read Figure 4 and Figure 6 In some embodiments, the lifting and grinding mechanism 40 may further include: a structural frame 4120, which is movably disposed on the lifting cylinder 410 and can reciprocate along a first direction relative to the lifting cylinder 410. In this embodiment, the first direction may be a vertical direction, that is, an up-and-down direction. A support frame 440 may be movably disposed on the structural frame 4120 and can reciprocate along a second direction relative to the structural frame 4120, wherein the first direction is perpendicular to the second direction, that is, in this embodiment, the support frame 440 may move horizontally relative to the structural frame 4120, that is, move left and right.

[0068] In this embodiment, the structural frame 4120 can slide along the first direction on the first track, carrying the support frame 440 from the second functional cavity 120 into the first functional cavity 110, and then the clamping member 420 and the trigger member 430 connected to the support frame 440 can be used to grind the electrode sheet 310 or unlock the electrode sheet 310 from the base shaft 20 and grasp and fix the electrode sheet 310, and then the structural frame 4120 can continue to slide on the lifting cylinder 410 and bring the support frame 440 from the first functional cavity 110 to the second functional cavity 120, and then the support frame 440 can slide along the second direction relative to the structural frame 4120 and drive the electrode sheet 310 from directly above the base shaft 20 to the upper side of the base shaft 20, for example, the electrode sheet 310 can be brought out of the reaction chamber to facilitate the user to replace the electrode sheet 310.

[0069] Please also see Figure 4 and Figure 7In a more specific embodiment, the lifting and grinding mechanism 40 may further include: a transverse guide rail 4130, the transverse guide rail 4130 may be connected between the structural frame 4120 and the support frame 440, the transverse guide rail 4130 may reciprocate along the second direction relative to the structural frame 4120, and the support frame 440 may reciprocate along the second direction relative to the transverse guide rail 4130. That is to say, in this embodiment, the difference is equivalent to that in the aforementioned embodiment, a transverse guide rail 4130 is provided between the structural frame 4120 and the support frame 440, so that the support frame 440 can move farther in the second direction relative to the structural frame 4120, thereby making it easier for users to replace the electrode sheet 310.

[0070] The present application also does not limit the electrical connection method between the electrode sheet 310 and the base shaft 20. For example, in one embodiment, see Figure 8 The electrode sheet 310 may have a connection interface 313. It should be noted that the connection interface 313 has no polarity restriction. When the connection interface 313 is connected to the positive electrode, the electrode sheet 310 is the positive electrode sheet. When the connection interface 313 is connected to the negative electrode, the electrode sheet 310 is the negative electrode sheet. In two adjacent electrode sheets 310, the connection interface 313 of one electrode sheet 310 can be connected to the positive electrode, and the other can be connected to the negative electrode to form a loop, so that the electric flocculation operation can be performed.

[0071] See also Fig. 9 The base shaft 20 may include a first shaft body 210, a second shaft body 220, a first wiring group and a second wiring group, wherein the first shaft body 210 may be fixedly connected to the reaction chamber 10, the second shaft body 220 may be sleeved on the outer surface of the first shaft body 210 and rotatably cooperate with the first shaft body 210, and the electrode sheet 310 may be connected to the second shaft body 220. At this time, the second shaft body 220 may be rotated so that the electrode sheets 310 at different positions can cooperate with the clamping member 420 to perform grinding operations on the electrode sheets 310 or grab the electrode sheets 310.

[0072] In one embodiment, the sewage treatment device 1 may further include a first driving member 50, which may be connected to the base shaft 20, and specifically connected to the second shaft body 220, and used to drive the second shaft body 220 to rotate, so that the rotation of the second shaft body 220 can be more automated. It should be noted that the embodiment of the present application does not limit the specific structure of the first driving member 50. For example, in some embodiments, the first driving member 50 may be a cylinder or a motor, etc., which may be specifically configured according to actual conditions.

[0073] Furthermore, in one embodiment, the sewage treatment device 1 may further include an agitator 60, which may be connected to the base shaft 20, and specifically connected to the second shaft body 220, and the agitator 60 may extend along the radial direction of the second shaft body 220. The agitator 60 may be used to agitate the sewage in the first functional chamber 110 during the rotation of the second shaft body 220, so that the sewage in the first functional chamber 110 can be more evenly treated by electro-flocculation.

[0074] It should be noted that the embodiment of the present application does not limit the specific position of the agitator 60. For example, in one embodiment, the agitator 60 can be disposed between adjacent electrode sheets 310. The embodiment of the present application also does not limit the length of the agitator 60. For example, in one embodiment, the length of the agitator 60 in the radial direction of the base shaft 20 is greater than the length of the electrode sheet 310 in the radial direction of the base shaft 20. In some other embodiments, the agitator 60 can also be disposed at other positions, for example, it can be disposed on the electrode sheet 310, and the length of the agitator 60 can also be set according to actual conditions.

[0075] As mentioned above, in this embodiment, the first wiring group and the second wiring group can be arranged at intervals along the axial direction of the first shaft 210, and both the first wiring group and the second wiring group include positive electrode connectors 250 and negative electrode connectors 260 that are arranged alternately and at intervals along the axial direction of the first shaft 210. That is, in this embodiment, the first wiring group and the second wiring group are arranged one after the other in the radial direction of the first shaft 210, so as to match the position of the electrode sheet 310. It should be noted that due to Fig. 9 The cross-sectional view is shown. Since the first wiring group and the second wiring group are spaced apart in the axial direction of the base shaft 20, Fig. 9 Only the structure of the first wiring group or the second wiring group is shown.

[0076] A plurality of third wiring groups 270 may be provided on the second shaft 220, and each third wiring group 270 may include a first wiring mechanism 271 and a second wiring mechanism 272, wherein the first wiring mechanism 271 is connected to the first wiring group, and the second wiring mechanism 272 is connected to the second wiring group. The first wiring mechanism 271 and the second wiring mechanism 272 may each include a first conductive end 281 and a second conductive end 282, wherein the first conductive end 281 may be used to conduct with the electrode sheet 310, and the second conductive end 282 may be used to conduct with one of the first wiring group and the second wiring group. That is to say, the third wiring group 270, the first wiring group and the second wiring group together form a loop, wherein the first wiring mechanism 271 may be connected to the positive electrode connector 250 of the first wiring group and to the connection interface 313 of one of the electrode sheets 310, and the second wiring mechanism 272 may be connected to the negative electrode connector 260 of the second wiring group and to the connection interface 313 of another electrode sheet 310.

[0077] Alternatively, the first wiring mechanism 271 can be connected to the negative electrode connector 260 of the first wiring group and to the connection interface 313 of one of the electrode sheets 310 , and the second wiring mechanism 272 can be connected to the positive electrode connector 250 of the second wiring group and to the connection interface 313 of another electrode sheet 310 .

[0078] In this way, each electrode sheet 310 can be selectively used as a positive electrode plate or a negative electrode plate during the rotation of the second shaft body 220. Similarly, in this embodiment, the first wiring mechanism 271 and the second wiring mechanism 272 are also arranged to be staggered in the axial direction of the second shaft body 220, that is, one in front and one behind, which is also convenient for matching the position of the electrode sheet 310.

[0079] It is understandable that, generally speaking, in the process of electrocoagulation, the consumables are usually positive plates, so the alternating use of the positive plates and negative plates mentioned above can fully utilize the electrode plates, avoiding that only part of the electrode sheets 310 in the same group of electrode plate assemblies 30 are consumed as positive plates, and the other part of the electrode plates are not consumed as negative plates. When the lifting and grinding mechanism 40 grinds or clamps and replaces the electrode sheets 310 in a group of electrode plate assemblies 30, some of the electrode sheets 310 do not need to be replaced, resulting in a waste of resources. In this embodiment, the alternating switching of the polarity of the electrode sheets 310 is beneficial to prolonging the service life of the electrode plate assembly 30 and reducing the replacement frequency of the electrode plate assembly 30.

[0080] In addition, in some embodiments, the first wiring mechanism 271 and the second wiring mechanism 272 may further include a Hall switch 283, and the first conductive end 281 and the second conductive end 282 may be connected via the Hall switch 283. The electrode sheet 310 may be provided with a magnetic member 314, and the magnetic member 314 may be used to trigger the Hall switch 283. Specifically, when the lifting and grinding mechanism 40 drives the electrode plate assembly 30 to separate from the base shaft 20, the Hall switch 283 is disconnected, and when the electrode plate assembly 30 is connected to the base shaft 20, the Hall switch 283 is connected, so that the first wiring mechanism 271 or the second wiring mechanism 272 may be avoided or reduced from being exposed to sewage and electrochemically corroded.

[0081] Please also see Figure 8 and Fig.10 In one embodiment, a one-way conductive film 315 may be provided at the connection interface 313 of the electrode sheet 310, and the one-way conductive film 315 is used for one-way conductive connection interface 313, and the conductive direction is from the outside of the electrode sheet 310 to the inside of the electrode sheet 310. That is, when the connection interface 313 is connected to the first wiring mechanism 271 or the second wiring mechanism 272, the one-way conductive film 315 can be opened, so that the electrode sheet 310 is connected to the third wiring group 270. The one-way conductive film 315 can prevent the connection interface 313 from being contaminated by sewage during the installation of the electrode sheet 310 on the second shaft 220, resulting in the sewage blocking the connection interface 313, thereby affecting the installation of the electrode sheet 310 and the second shaft 220.

[0082] Please also refer to Figure 8-Figure 10 In some embodiments, the electrode plate assembly 30 may further include an insulating base 312, and the electrode sheet 310 may be installed in the insulating base 312. It should be noted that in this embodiment, the insulating base 312 only covers a portion of the electrode sheet 310, specifically, the area of ​​the electrode sheet 310 used for connection with the third wiring group 270, so as to avoid the area of ​​the electrode sheet 310 used for conduction being exposed. As mentioned above, the side of the connection interface 313 may be wrapped in the insulating base 312, and the unidirectional conductive film 315 may also be formed on the insulating base 312. When the user replaces the electrode sheet 310, he only needs to take the electrode sheet 310 out of the insulating base 312, and the insulating base 312 can be reused.

[0083] In summary, the sewage treatment device 1 provided in the embodiment of the present application is configured by setting a base shaft 20 in the first functional cavity 110 of the reaction chamber 10, and setting a plurality of groups of electrode plate assemblies 30 at intervals on the outer peripheral surface of the base shaft 20, each group of electrode plates includes a plurality of electrode sheets 310 arranged at intervals along the axial direction of the base shaft 20, and setting a lifting and grinding mechanism 40, and setting the lifting and grinding mechanism 40 so that when the lifting and grinding mechanism 40 is in the first position, the lifting and grinding mechanism 40 is located in the second functional cavity 120 on one side of the first functional cavity 110, and when the lifting and grinding mechanism 40 is in the second position, the lifting and grinding mechanism 40 at least partially extends into the first functional cavity 110 and into the gap between the electrode sheets 310, and the surface of the electrode sheets 310 can be polished at this time, and when the lifting and grinding mechanism 40 is in the third position, the lifting and grinding mechanism 40 can unlock the electrode sheet 310 and the base, and can clamp the electrode sheet 310 to take the electrode sheet 310 out of the first functional cavity 110. In this embodiment, since a plurality of electrode plate assemblies 30 are arranged at intervals on the outer peripheral surface of the base shaft 20, during the process of removing the electrode sheet 310 or grinding the electrode sheet 310, except for the electrode sheet 310 in contact with the lifting and grinding mechanism 40, the remaining electrode sheets are not affected. Therefore, the lifting and grinding mechanism 40 provided in the embodiment of the present application can grind or replace the electrode sheet 310 while continuing to treat sewage, thereby making the entire sewage treatment device 1 have no vacuum period, which is conducive to the continuous treatment of sewage.
