Description

Technical Field

[0001] This application relates to the technical field of wastewater treatment, and in particular to an electrodynamic membrane treatment device. Background Technology

[0002] Dynamic membranes refer to membranes formed by the dynamic deposition of small particles on porous media (such as porous ceramics, sintered metals, and porous polymers). Electrocatalytic oxidation is an emerging wastewater treatment technology that can effectively remove recalcitrant organic pollutants from wastewater. This technology utilizes the highly oxidizing hydroxyl radicals generated by an electrocatalytically active anode material under energized conditions to degrade organic pollutants and transform them into harmless substances.

[0003] Currently, Chinese patent CN109354161A discloses an electrochemically coupled dynamic membrane module and reactor for wastewater treatment. The membrane module includes a membrane frame, a plastic mesh, a titanium mesh, an activated carbon fiber felt, a dynamic membrane substrate, and wires. The membrane frame is provided with a suction port communicating with the inner cavity of the membrane frame. The suction port is connected to the effluent pipe in the reactor. The titanium mesh is located inside the membrane cavity of the membrane frame and is connected to the negative terminal of the power supply through the wires. The plastic mesh is located on both sides of the outer side of the membrane frame. The activated carbon fiber felt is attached to the outer side of the plastic mesh and is connected to the positive terminal of the power supply in the reactor through the wires. The dynamic membrane substrate is located on the outer side of the activated carbon fiber felt.

[0004] Because each membrane module is equipped with wires, when there are multiple membrane modules in the reactor, the wires on the membrane modules will become tangled. As a result, when replacing a membrane module, it takes time to untangle the wires before replacement, which takes a long time and reduces efficiency. Summary of the Invention

[0005] To improve efficiency, this application provides an electrodynamic membrane processing apparatus.

[0006] This application provides an electrodynamic membrane processing device, which adopts the following technical solution:

[0007] An electrodynamic membrane treatment device includes a main body and a wastewater treatment mechanism. The wastewater treatment mechanism includes an electrolysis component, a membrane component, and an effluent component. The electrolysis component includes an anode plate and a cathode plate, which are respectively disposed at both ends of the main body. Multiple membrane components are provided, each including an upper plug, a lower plug, a metal membrane element, and a permeate pipe. The upper and lower plugs are respectively located at both ends of the metal membrane element, and the permeate pipe is disposed on the upper plug. The metal membrane elements in the multiple membrane components are all located between the anode plate and the cathode plate. The permeate pipes in the multiple membrane components are all connected to the effluent component.

[0008] By adopting the above technical solution, an electric potential is generated between the anode plate and the cathode plate. A cathode charge is generated on the metal membrane near the anode plate, and an anode charge is generated on the metal membrane near the cathode plate. This facilitates electrolysis, promotes the production of microorganisms, and reduces the fouling of the metal membrane, thereby improving the wastewater treatment effect. Moreover, each membrane module is independent and has no wires, which improves efficiency.

[0009] Optionally, the main body is provided with two clamping and adjusting mechanisms. Each clamping and adjusting mechanism includes a lifting component, a first adjusting block, a second adjusting block, a third adjusting block, a clamping block, and an adjusting assembly. Two lifting components are provided, each located on one side of the main body. Each lifting component is provided with a first adjusting block. The second adjusting block is slidably disposed on the first adjusting block. Two third adjusting blocks are provided, each slidably disposed on the second adjusting block. Each third adjusting block is provided with a clamping block, and a clamping space is formed between the two clamping blocks. The upper blocking block is located within the clamping space of one clamping and adjusting mechanism, and the lower blocking block corresponds to the clamping space of one clamping and adjusting mechanism. The adjusting assembly is disposed on the first adjusting block, and the second adjusting block and the clamping block are both connected to the adjusting assembly.

[0010] By adopting the above technical solution, a crane is connected to the upper blocking block, and the two ends of the upper blocking block are respectively located in two clamping spaces in one clamping adjustment mechanism, while the two ends of the lower blocking block are respectively located in two clamping spaces in another clamping adjustment mechanism. Then, the adjustment assembly is activated, causing the two second adjustment blocks in each clamping adjustment mechanism to move towards each other. The two third adjustment blocks located on the same second adjustment block drive the two clamping blocks to move towards each other, so that the second adjustment block and the clamping block in one clamping adjustment mechanism both abut against the upper blocking block, and the second adjustment block and the clamping block in the other clamping adjustment mechanism both abut against the lower blocking block, thereby fixing the membrane module.

[0011] Optionally, the first adjusting block has a first groove, the second adjusting block has a first cavity, and the second adjusting block has two first through holes communicating with the first cavity. The two third adjusting blocks are respectively slidably disposed within the two first through holes. The adjusting assembly includes a sliding block, an adjusting motor, an adjusting screw, a drive shaft, a first gear, and a first rack. One end of the sliding block is slidably disposed within the first groove, and the second adjusting block is fixedly connected to the sliding block. The adjusting motor is disposed on the first adjusting block. The sliding block has a second groove, and the sliding block has a threaded hole communicating with the second groove. One end of the rod is connected to the output shaft of the adjusting motor, and the other end passes through the threaded hole and is located in the second groove. The adjusting screw is threadedly connected to the threaded hole. The drive shaft is connected to the adjusting screw located in the second groove, and a third groove is provided on the drive shaft. The drive shaft is rotatably mounted on the second adjusting block, one end of the drive shaft is slidably mounted in the third groove, and the other end is located in the first cavity. The first gear is keyed to the drive shaft located in the first cavity. There are two first racks, and the two first racks are respectively mounted on the two third adjusting blocks, and both first racks mesh with the first gear.

[0012] By adopting the above technical solution, the output shaft of the adjusting motor drives the adjusting screw to rotate, the adjusting screw drives the sliding block to slide in the first groove, the sliding block drives the second adjusting block to move, and the drive shaft will slide in the third groove; when the adjusting screw rotates, the drive shaft on the adjusting screw drives the drive shaft to rotate, the first gear on the drive shaft drives the two first racks to move in opposite directions or back to back, and the two first racks will drive the two third adjusting blocks to move in opposite directions or back to back.

[0013] Optionally, the clamping block includes a first connecting block, a second connecting block, a slider, and a first spring. The first connecting block is fixedly connected to the third adjusting block, and a sliding groove is formed on the first connecting block. The slider is slidably disposed within the sliding groove. One end of the first spring is connected to the slider, and the other end is connected to the second connecting block. The second connecting block is fixedly connected to the slider. Both the upper and lower blocking blocks have connecting grooves that engage with the second connecting block, and both the upper and lower blocking blocks have drainage holes that communicate with the connecting grooves. When the second connecting block is located within the connecting groove, the first connecting block can abut against the upper or lower blocking block, and the upper or lower blocking block, together with the second connecting block, covers the sliding groove.

[0014] By adopting the above technical solution, since the clamping block is located inside the pool, especially the clamping block corresponding to the lower block, sludge or large particles of impurities will be attached to it. Therefore, when the two third adjusting blocks move in opposite directions, the first connecting block on the two third adjusting blocks drives the second connecting block to move, causing the second connecting block to enter the connecting groove. The sludge on the side wall of the second connecting block, except for the side away from the first connecting block and the side wall close to the first connecting block, will be scraped off by the upper or lower block. When the second connecting block is completely in the connecting groove, the lifting component in one of the clamping and adjusting mechanisms is activated, causing the third adjusting block to drive the second connecting block to move. The movement of the first connecting block causes the side wall of the first connecting block near the second connecting block to abut against the upper or lower block. Since the side wall of the first connecting block near the second connecting block is initially covered by the second connecting block, no sludge or large particles of impurities will adhere to the side wall of the first connecting block near the second connecting block. Moreover, the side wall of the first connecting block near the second connecting block will also scrape off some of the sludge or large particles of impurities adhering to the upper or lower block, so that the part of the upper or lower block that abuts against the first connecting block is also free of sludge or large particles of impurities. In this way, the clamping block will better clamp the upper or lower block.

[0015] Optionally, the first connecting block is provided with a positioning mechanism connected to the second connecting block. The positioning mechanism includes a positioning block, a second spring, a first adjusting block, and a first adjusting component. The second connecting block has a second cavity and a second through hole communicating with the second cavity. The first connecting block has a positioning groove. The positioning block is slidably disposed in the second through hole, with one end of the positioning block located in the second cavity and the other end located in the positioning groove. One end of the second spring is connected to the positioning block and the other end is connected to the second connecting block. The first adjusting block is slidably disposed in the positioning groove through the first adjusting component, and the first adjusting block can abut against the positioning block.

[0016] By adopting the above technical solution, before the second connecting block enters the connecting groove, the end of the positioning block away from the second cavity is located in the positioning groove; when the second connecting block is fully entered into the connecting groove, the first adjusting component is activated first, the first adjusting component drives the first adjusting block to move, the first adjusting block pushes the positioning block to move, so that the positioning block is no longer located in the positioning groove, and the first adjusting block will not enter the second through hole; finally, the lifting component is activated, so that the first connecting block abuts against the upper or lower blocking block; because the end of the positioning block away from the second cavity is located in the positioning groove before the second connecting block enters the connecting groove, the first connecting block and the second connecting block will not move relative to each other under the action of the positioning block, thereby improving the stability when the first connecting block and the second connecting block are connected.

[0017] Optionally, the second connecting block has a third through hole communicating with the second cavity, and both the upper and lower blocking blocks have limiting grooves communicating with the connecting groove; the second connecting block is provided with a limiting mechanism, which includes a limiting block, a second adjusting block, a third spring, and a second adjusting component. The limiting block is slidably disposed in the third through hole, with one end of the limiting block located in the second cavity and the other end located in the limiting groove; the second adjusting block is slidably disposed in the limiting groove and can abut against the limiting block; one end of the third spring is connected to the second adjusting block and the other end is connected to the side wall of the limiting groove; the second adjusting component is disposed on the second connecting block, and the limiting block is connected to the second adjusting component.

[0018] By adopting the above technical solution, when the limiting block is not fully inserted into the limiting groove, the second adjusting block abuts against the second connecting block located in the connecting groove near the side wall of the second connecting block, and when the second connecting block is fully inserted into the connecting groove, the limiting block abuts against the second adjusting block; when the positioning block is no longer engaged with the positioning groove, the positioning block drives the limiting block to move through the second adjusting component, causing the limiting block to move into the limiting groove, and the limiting block pushes the second adjusting block to move, and the third spring changes from normal to compressed state; the limiting mechanism can connect the limiting block on the second connecting block with the upper or lower blocking block, thereby improving the stability of the second connecting block on the upper or lower blocking block.

[0019] Optionally, both the upper and lower blocking blocks have a third cavity communicating with the limiting groove, and both the upper and lower blocking blocks have a communicating groove communicating with the third cavity; a cleaning mechanism is provided on the upper or lower blocking block, the cleaning mechanism including a third adjusting block, a scraping block, and a third adjusting component, two third adjusting blocks are provided, both of which are slidably disposed in the communicating groove; the scraping block is disposed on the third adjusting block and abuts against a second connecting block located in the connecting groove; both the upper and lower blocking blocks are provided with the third adjusting component, and both of the third adjusting blocks are connected to the third adjusting component.

[0020] By adopting the above technical solution, since sludge or large particles of impurities will also adhere to the side of the second connecting block away from the first connecting block, and the more times the membrane module is replaced, the more sludge or large particles of impurities will adhere; when there is a lot of sludge or large particles of impurities, it will affect the second connecting block from entering the connecting groove; therefore, each time the membrane module is replaced, when the second connecting block enters the connecting groove, the second adjusting block will drive the two third adjusting blocks to move through the third adjusting component, and the third adjusting blocks will drive the cleaning block to move, so that the cleaning block cleans a part of the sludge on the second connecting block, reducing the phenomenon that the second connecting block cannot completely enter the connecting groove of the subsequent membrane module.

[0021] Optionally, the water outlet assembly includes a main pipe and connecting pipes. The connecting pipes are disposed on the main pipe, and the number of connecting pipes corresponds one-to-one with the number of water production pipes. The connecting pipes are connected to the corresponding water production pipes.

[0022] By adopting the above technical solution, the sewage in the treatment chamber enters the metal membrane through the filter interface, and then enters the connecting pipe through the product water pipe, and finally enters the main pipe.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The wastewater treatment facility described in this application can not only improve wastewater treatment efficiency, but also increase overall efficiency;

[0025] 2. The limiting mechanism enables the limiting block on the second connecting block to connect with the upper or lower blocking block, thereby improving the stability of the second connecting block on the upper or lower blocking block. Attached Figure Description

[0047] When the third adjusting block 54 moves, it drives the first connecting block 61 to move, and the first connecting block 61 drives the second connecting block 62 to move, so that the second connecting block 62 enters the connecting groove 421. Then, the hydraulic cylinder corresponding to the lower blocking block 42 is activated, so that the third adjusting block 54 drives the first connecting block 61 to move. The slider 63 on the second connecting block 62 will slide in the groove 611 of the first connecting block 61, so that the first connecting block 61 abuts against the side wall of the lower blocking block 42, and the lower blocking block 42 and the second connecting block 62 together cover the groove 611.

When the second spring 72 is in the normal state, the end of the positioning block 71 away from the second cavity is located in the positioning groove. A first adjusting block 73 that abuts against the positioning block 71 is slidably connected in the positioning groove of the first connecting block 61. A first adjustment component 74 is provided on the first connecting block 61. The first adjustment component 74 includes an adjustment motor 741 fixedly connected to the first connecting block 61. A second gear 742 is keyed to the output shaft of the adjustment motor 741. A second rack 743 that meshes with the second gear 742 is integrally provided on the first adjustment block 73.

[0049] Before the second connecting block 62 enters the connecting groove 421, the end of the positioning block 71 away from the second cavity is located in the positioning groove and abuts against the first adjusting block 73. When the second connecting block 62 is completely located in the connecting groove 421, the adjusting motor 741 is started first. The output shaft of the adjusting motor 741 drives the second gear 742 to rotate. The second gear 742 drives the second rack 743 to move. The second rack 743 drives the first adjusting block 73 to move towards the second connecting block 62. The first adjusting block 73 pushes the positioning block 71 to move, so that the positioning block 71 is no longer located in the positioning groove, and the first adjusting block 73 will not enter the second through hole. At this time, the second spring 72 is in a stretched state. Finally, the hydraulic cylinder is started to make the first connecting block 61 abut against the upper block 41 or the lower block 42.

[0050] refer to Figure 3 , Figure 5 and Figure 6 In order to improve the stability of the second connecting block 62 in the connecting groove 421, a limiting mechanism 8 is provided on the second connecting block 62.

[0051] The limiting mechanism 8 includes a limiting block 81 that is slidably connected in the third through hole. When the second spring 72 is in the normal state, one end of the limiting block 81 is located in the second cavity and the other end is located in the third through hole. When the second spring 72 is in the stretched state, one end of the limiting block 81 is located in the second cavity and the other end is located in the limiting groove. A second adjusting block 82 is slidably connected in the limiting groove. A third spring 83 is connected to the second adjusting block 82. The end of the third spring 83 away from the second adjusting block 82 is connected to the side wall of the connecting groove 421. The second connecting block 62 is provided with a second adjusting component 84. The second adjusting component 84 includes a first adjusting shaft 841 rotatably connected in the second cavity, a third gear 843 keyed to the first adjusting shaft 841, and a third rack 842 integrally provided on the positioning block 71 located in the second cavity, which meshes with the third gear 843; a fourth gear 844 keyed to the end of the first adjusting shaft 841 away from the third gear 843, and a fourth rack 845 keyed to the limiting block 81 located in the second cavity, which meshes with the fourth gear 844.

[0052] When the second spring 72 is in its normal state, the third spring 83 is also in its normal state. When the limiting block 81 is not fully inserted into the limiting groove, the second adjusting block 82 abuts against the second connecting block 62 located in the connecting groove 421 near the side wall of the second connecting block 62. When the second connecting block 62 is fully located in the connecting groove 421, the limiting block 81 abuts against the second adjusting block 82. When the positioning block 71 is no longer engaged with the positioning groove, the second spring 72 is in a stretched state. The third rack 842 on the positioning block 71 drives the third gear 843 to rotate. The third gear 843 drives the first adjusting shaft 841 to rotate. The fourth gear 844 on the first adjusting shaft 841 drives the fourth rack 845 to move. The fourth rack 845 drives the limiting block 81 to move, causing the limiting block 81 to move into the limiting groove. The limiting block 81 pushes the second adjusting block 82 to move, and the third spring 83 changes from a normal state to a compressed state.

When the second connecting block 62 is completely located in the connecting groove 421, the second adjustment block 53 will abut against the upper blocking block 41 or the lower blocking block 42.

[0058] When the second connecting block 62 is completely within the connecting groove 421, the adjusting motor 741 is activated, causing the first adjusting block 73 to push the positioning block 71 to move, so that the positioning block 71 is no longer within the positioning groove, and the first adjusting block 73 will not enter the second through hole; the third rack 842 on the positioning block 71 drives the third gear 843 to rotate, the third gear 843 drives the first adjusting shaft 841 to rotate, the fourth gear 844 on the first adjusting shaft 841 drives the fourth rack 845 to move, the fourth rack 845 drives the limiting block 81 to move, and the limiting block 81 pushes... The second adjusting block 82 moves, causing the limiting block 81 to move into the limiting groove. When the second adjusting block 82 moves, the fifth rack 931 on the second adjusting block 82 drives the fifth gear 932 to rotate, the fifth gear 932 drives the second adjusting shaft 933 to rotate, the second adjusting shaft 933 drives the sixth gear 934 to rotate, the sixth gear 934 drives the two sixth racks 935 to move, the sixth racks 935 drive the third adjusting block 91 to move, and the third adjusting block 91 drives the cleaning block 92 to move, so that the cleaning block 92 cleans a portion of the sludge on the second connecting block 62.

[0059] Then, the hydraulic cylinder corresponding to the lower block 42 is activated, causing the third adjusting block 54 to drive the first connecting block 61 to move. The slider 63 on the second connecting block 62 will slide within the groove 611 of the first connecting block 61, causing the first connecting block 61 to abut against the side wall of the lower block 42. The lower block 42 and the second connecting block 62 together cover the groove 611. Then, the hydraulic cylinder corresponding to the lower block 42 is activated, causing the third adjusting block 54 to drive the first connecting block 61 to move. The slider 63 on the second connecting block 62 will slide within the groove 611 of the first connecting block 61, causing the first connecting block 61 to abut against the side wall of the upper block 41. The upper block 41 and the second connecting block 62 together cover the groove 611.
