Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, in particular to sewage treatment equipment for treating domestic sewage. Background Art

[0002] In chemical companies, there are laboratories for researching new products or improving old products. A large amount of chemical agents are used in the experiment, which will produce sewage. Since different chemical agents are used in the experiment, the discharge standards of experimental sewage and production sewage are different, so the experimental sewage needs to be treated separately.

[0003] Considering that in the prior art, chemical agents are added when treating sewage to render the chemicals used in the experiment harmless, this process not only takes a long time, but also produces some by-products, which still require many steps to process. In addition, since some equipment in the prior art cannot self-clean itself, the generation of by-products may lead to poor purification effect or blockage, and after long-term use, the sewage treatment may not meet the standards. Summary of the invention

[0004] The object of the present invention is to provide a sewage treatment device for treating domestic sewage to solve the problems raised in the above background technology.

[0005] To solve the above technical problems, the present invention is achieved through the following technical solutions: The present invention is a sewage treatment device for treating domestic sewage, comprising a sewage treatment shell, a cover plate is clamped on the top of the sewage treatment shell, a clean water tank is fixedly installed on the bottom of the sewage treatment shell, an adsorption plate is fixedly connected to the middle of the inner wall of the sewage treatment shell, a purification mechanism is fixedly connected to the bottom of the inner wall of the sewage treatment shell; a filter mechanism is clamped on the top of the purification mechanism; the outer wall of the filter mechanism is rotatably connected to the inner wall of the sewage treatment shell; The purification mechanism includes a waterproof shell, the bottom of which is fixedly connected to the bottom of the inner wall of the sewage treatment shell, a cavity is opened inside the waterproof shell, and a driving motor is fixedly connected to the inner wall of the cavity; the output end of the driving motor is fixedly connected to a driving gear; an inner shaft gear is meshed on the side of the driving gear away from the driving motor, and an outer shaft gear is meshed on the side of the driving gear away from the driving motor; an inner rotating shaft is fixedly connected to the inner wall of the inner shaft gear; an outer rotating shaft is fixedly connected to the inner wall of the outer shaft gear; a filtering mechanism is clamped on the top of the inner rotating shaft; a rotating rod is fixedly connected to the outer wall of the outer rotating shaft, and there are three groups of rotating rods; an adsorption block is fixedly connected to the outer wall of each group of rotating rods, and there are multiple groups of adsorption blocks, and the side of the adsorption block that is in the same direction of rotation is an inclined surface.

[0006] By adopting the above technical solution, when sewage enters, the driving motor is started to rotate the rotating rod, and the rotating rod can drive the adsorption block to rotate synchronously. When the driving motor is started, the adsorption block and the adsorption plate are energized, and they are positive and negative poles respectively. By energizing, an electrostatic field can be formed between the adsorption block and the adsorption plate. At this time, when sewage flows through, it will adsorb ions in it, especially calcium and magnesium. Too much calcium and magnesium in the water will cause scale to form in metal objects. For the situation in the laboratory, after the water circulates, the high impurity content in the water will also cause the experimental results to deviate too much.

[0007] Furthermore, a stirring impeller is clamped at the bottom of the inner rotating shaft; the bottom of the stirring impeller is rotatably connected to a filter tank; the inner wall of the sewage treatment shell near the bottom is fixedly connected to a smart water valve; the outer wall of the stirring impeller is rotatably connected to the inner wall of the smart water valve; the inner wall of the clean water tank is clamped with a filter element body; the outer wall of the filter tank is provided with filter holes, and there are multiple groups of filter holes, the outer wall of the filter tank is in contact with the inner wall of the filter element body, the bottom of the filter tank is fixedly connected to a support frame, and the bottom of the support frame is fixedly connected to the bottom of the inner wall of the clean water tank.

[0008] By adopting the above technical solution, the ionic impurities in the sewage can be purified to the discharge standard before flowing in through the setting of the intelligent water valve during sewage treatment. After the sewage flows into the filter tank, the filter holes opened on the filter tank can block smaller impurities to prevent debris from entering the filter element body. The stirring impeller can be set to stir the internal sewage and impurities to rotate to prevent impurities from adhering to the filter holes of the filter tank and causing the sewage to be unable to flow out. When there are more smaller impurities in the use environment, the size of the stirring impeller and the filter tank can be increased to accommodate more impurities.

[0009] Furthermore, the filtering mechanism includes a filter plate, the outer wall of the filter plate is clamped with the inner wall of the sewage treatment shell, the inner wall of the filter plate is provided with through holes, and there are multiple groups of through holes, the inner wall of the filter plate is rotatably connected to a rotating shaft, and the inner wall of the filter plate is rotatably connected to the outer wall of the outer rotating shaft; the bottom of the rotating shaft is clamped with the top of the inner rotating shaft, the outer wall of the rotating shaft is fixedly connected to a cutting impeller, and there are three groups of cutting impellers, and the outer wall of the rotating shaft is fixedly connected to a stirring rod, and there are four groups of stirring rods.

[0010] By adopting the above technical solution, when sewage enters the equipment, impurities can be filtered out through the setting of the filter plate, and the rotating shaft can rotate clockwise, driving the cutting impeller and the stirring rod to move clockwise; when sewage enters, the water pressure will impact the cutting impeller, and can assist the rotating shaft to rotate, thereby reducing energy use; when the stirring rod rotates, it will stir the water flow and form a vortex. At this time, since the water pressure around is higher than the central water pressure, the impurities will flow to the center of the filter plate. At this time, even if there are more impurities inside, they will not block all the through holes, and there are no through holes in the central part of the filter plate, so the impurities flowing to the center of the filter plate will not affect the filtration efficiency.

[0011] Furthermore, a first sealing groove is provided on the inner wall of the waterproof shell, and there are two groups of first sealing grooves, the inner wall of the first sealing groove is fixedly connected with a first sealing ring, the inner wall of one group of the first sealing rings is rotatably connected to the inner wall of the inner rotating shaft, and the inner wall of the other group of the first sealing rings is rotatably connected to the inner wall of the outer rotating shaft; a second sealing groove is provided on the inner wall of the filter plate, the inner wall of the second sealing groove is fixedly connected with a second sealing ring, and the inner wall of the second sealing ring is rotatably connected to the inner wall of the rotating shaft; a third sealing groove is provided on the inner wall of the smart water valve, the inner wall of the third sealing groove is fixedly connected with a third sealing ring, and the inner wall of the third sealing ring is rotatably connected to the inner wall of the stirring impeller.

[0012] By adopting the above technical scheme, the first sealing ring can be set to prevent water from flowing into the interior of the waterproof shell, thereby causing damage to the equipment when it encounters water; the second sealing ring can be set to prevent water from entering the interior of the waterproof shell through the gap between the inner rotating shaft and the rotating shaft; the third sealing ring can be set to prevent sewage that has not yet met the standards after internal treatment from entering the interior of the filter tank through the gap, thereby ensuring the quality of sewage treatment and enabling the sewage treatment to meet the treatment standards.

[0013] Furthermore, each group of through holes is inclined, and portions of the through holes that are higher than the top surface of the filter plate are raised.

[0014] By adopting the above technical solution, the inclination direction of the through hole is the same as the rotation direction of the rotating shaft. When the stirring rod stirs the water flow to make the water flow rotate clockwise, it can flow out quickly, and when it flows clockwise to the bottom, it collides with the purification mechanism rotating counterclockwise, which can increase the sewage treatment efficiency. The inclined convex design can prevent impurities from getting stuck in the through hole. Since the height of the through hole is increased, when the impurities get stuck in the through hole, they need to lift themselves up a part first, but the water flow stirred by the stirring rod will absorb the impurities, thereby preventing the impurities from blocking the through hole. The convex design can be used for stamping dies or retain the residual materials of stamping. The method of retaining the residual materials is more economical and does not require additional molds. However, the sharp edges need to be polished before use to prevent scratches. Furthermore, a water inlet is fixedly connected to the top of the cover plate, and a thread is arranged on the inner wall of the water inlet; a through groove is opened on one side of the clean water tank, and a water outlet is fixedly connected to the inner wall of the through groove.

[0015] By adopting the above technical solution, sewage can be discharged into the pipe through the setting of the water inlet and connected through the thread. The thread can increase the sealing performance while fixing the pipe, so that the water and gas inside will not flow out from the gap; the treated water can be discharged through the setting of the water outlet, and a water pump can be installed inside the clean water tank, and the drain pipe can be connected to other equipment for use, storage or direct discharge.

[0016] Furthermore, the rotating rod and the rotating direction are flattened to form an elliptical shape.

[0017] By adopting the above technical solution, the oblate round processing can reduce the resistance of water flow through the streamlined shape when the rotating rod rotates, thereby reducing energy consumption.

[0018] Furthermore, the edge of the cutting impeller is a bevel and has cutting capability.

[0019] By adopting the above technical solution, through the design of the cutting impeller, some larger impurities in the sewage can be cut by the cutting impeller, so that the impurities are smaller when entering the equipment, so as to avoid excessive accumulation of impurities that block the through holes, thereby affecting the sewage treatment efficiency, and collision may occur when the stirring rod stirs the water flow, causing damage to the equipment. At the same time, it can also avoid that larger impurities cannot be affected by the water flow and flow to the center of the filter plate.

[0020] Furthermore, a clamping block is fixedly connected to the bottom of the cover plate, and there are four groups of clamping blocks; the inner wall of the sewage treatment shell is provided with a clamping groove, and there are four groups of clamping grooves; the inner wall of each group of the clamping grooves is clamped with the outer wall of the clamping block.

[0021] By adopting the above technical solution, through the setting of the snap-in block and the snap-in groove, when cleaning is needed, the snap-in block and the snap-in groove can be lost by directly rotating the cover plate, and the cover plate can be pulled up to open the top of the device. When cleaning, the filter mechanism part can be removed as a whole for cleaning, thereby ensuring the simplicity of cleaning.

[0022] The present invention has the following beneficial effects: 1. When sewage enters, the present invention starts the driving motor to rotate the rotating rod, and the rotating rod can drive the adsorption block to rotate synchronously. When the driving motor is started, the adsorption block and the adsorption plate are energized, and they are respectively positive and negative electrodes. By energizing, an electrostatic field can be formed between the adsorption block and the adsorption plate. At this time, when sewage flows through, it will adsorb ions therein, especially calcium and magnesium. If there are too much calcium and magnesium in the water, scale will be generated in metal objects. According to the situation in the laboratory, after the water circulates, the high impurity content in the water will also cause excessive deviation in the experimental results.

[0023] 2. When sewage enters the device, the present invention can filter impurities through the setting of the filter plate, and the rotating shaft rotates clockwise, driving the cutting impeller and the stirring rod to move clockwise; when sewage enters, the water pressure will impact the cutting impeller, and can assist the rotating shaft to rotate, thereby reducing the use of energy; when the stirring rod rotates, it will stir the water flow and form a vortex. At this time, since the water pressure around is higher than the central water pressure, the impurities will flow to the center of the filter plate. At this time, even if there are more impurities inside, they will not block all the through holes, and there is no through hole in the central part of the filter plate, so the impurities flowing to the center of the filter plate will not affect the filtration efficiency.

[0024] 3. The inclination direction of the through hole of the present invention is the same as the rotation direction of the rotating shaft. When the stirring rod stirs the water flow to make the water flow rotate clockwise, it can flow out quickly, and when it flows clockwise to the bottom, it collides with the counterclockwise rotating purification mechanism. At this time, the sewage treatment efficiency can be increased. The inclined protrusion design can prevent impurities from being stuck in the through hole, and the protrusion design can be used for stamping molds or retaining stamping residues. The method of retaining residues is more economical and does not require additional molds. However, the sharp edges need to be polished before use to prevent scratches.

[0025] 4. The present invention can purify the ionic impurities in the sewage to the discharge standard before the sewage flows into the sewage during sewage treatment through the setting of the intelligent water valve. After the sewage flows into the filter tank, the filter holes opened on the filter tank can block smaller impurities to prevent debris from entering the filter element body. The stirring impeller can be set to stir the sewage and impurities inside to rotate to prevent impurities from adhering to the filter holes of the filter tank and causing the sewage to be unable to flow out. When there are many smaller impurities in the use environment, the size of the stirring impeller and the filter tank can be increased to accommodate more impurities.

[0026] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figure 1-Figure 8As shown, the present invention is a sewage treatment device for treating domestic sewage, comprising a sewage treatment shell 1, a cover plate 11 is clamped on the top of the sewage treatment shell 1, a clean water tank 12 is fixedly installed on the bottom of the sewage treatment shell 1, an adsorption plate 18 is fixedly connected to the middle of the inner wall of the sewage treatment shell 1, a purification mechanism 2 is fixedly connected to the bottom of the inner wall of the sewage treatment shell 1; a filtering mechanism 3 is clamped on the top of the purification mechanism 2; the outer wall of the filtering mechanism 3 is rotatably connected to the inner wall of the sewage treatment shell 1; The purification mechanism 2 includes a waterproof shell 21, the bottom of which is fixedly connected to the bottom of the inner wall of the sewage treatment shell 1, a cavity is opened inside the waterproof shell 21, and a driving motor 22 is fixedly connected to the inner wall of the cavity; a driving gear 23 is fixedly connected to the output end of the driving motor 22; an inner shaft gear 24 is meshed on the side of the driving gear 23 away from the driving motor 22, and an outer shaft gear 25 is meshed on the side of the driving gear 23 away from the driving motor 22; an inner rotating shaft is fixedly connected to the inner wall of the inner shaft gear 24; an outer shaft gear 25 is fixedly connected to the outer wall of the outer shaft gear 25; a filtering mechanism 3 is clamped on the top of the inner rotating shaft; a rotating rod 26 is fixedly connected to the outer wall of the outer rotating shaft, and there are three groups of rotating rods 26; an adsorption block 27 is fixedly connected to the outer wall of each group of rotating rods 26, and there are multiple groups of adsorption blocks 27, and the adsorption block 27 is inclined on the side with the same rotation direction.

[0032] In this embodiment, in the prior art, chemical agents are added when treating sewage to render the chemical agents used in the experiment harmless. However, this process not only takes a long time, but also produces some by-products, which still require many steps to process. In addition, since some equipment in the prior art cannot self-clean itself, the generation of by-products may lead to poor purification effects or blockage, and after long-term use, the sewage treatment may not meet the standards.

[0033] When sewage enters, the driving motor 22 is started to rotate the driving gear 23, and the rotation of the driving gear 23 can make the inner shaft gear 24 and the outer shaft gear 25 rotate in different directions. At this time, the inner shaft gear 24 will drive the inner rotating shaft to rotate in the clockwise direction, and the outer shaft gear 25 will drive the outer rotating shaft to rotate in the counterclockwise direction. When the outer rotating shaft rotates, it will drive the rotating rod 26 and the adsorption block 27 to rotate in the same direction; while starting the driving motor 22, the adsorption block 27 and the adsorption plate 18 are energized, and the adsorption block 27 and the adsorption plate 18 are respectively positive and negative poles. By energizing, an electrostatic field can be generated between the adsorption block 27 and the adsorption plate 18, and the charged particles in the sewage will move to the electrodes of opposite charge. At this time, the ions in the sewage can be adsorbed, and the adsorption effect on calcium and magnesium is better. Moreover, the rotation can make the electrical adsorption more sufficient, so that the sewage treatment is purer; when the ions are adsorbed, the water temperature will rise due to the movement of the ions and the resistance of the water to the electric current, and the water temperature can also be increased. The sewage is sterilized at high temperature; since electrosorption is used for sewage treatment, the same effect as electrolysis of water will be produced in the process of electrosorption. Water will be electrolyzed into hydrogen and oxygen, and due to the low density of hydrogen and oxygen, they will float upward to the top of the equipment. At this time, a vent can be selectively opened on the top of the cover plate 11 to collect the gas through the vent, which can not only fill the consumables required for the laboratory, but also because hydrogen is a clean energy and will not pollute the atmosphere when burned. The excess hydrogen can be used as laboratory life gas and can be provided to the laboratory for daily use; when cleaning is required, the adsorption block 27 and the adsorption plate 18 can be powered off and clean water can be added inside. At this time, the ions adsorbed on the surface of the adsorption block 27 and the adsorption plate 18 will fall off due to the loss of the electrostatic field and be washed away from the surface of the adsorption block 27 and the adsorption plate 18 by the clean water, and can be collected when discharged. Since the sewage is cleaned by physical means, no by-products are produced, and the discharged water can be collected after cleaning and can also be reused.

[0034] Specifically, a stirring impeller 28 is clamped at the bottom of the inner rotating shaft; a filter tank 29 is rotatably connected to the bottom of the stirring impeller 28; an intelligent water valve 15 is fixedly connected to the inner wall of the sewage treatment shell 1 near the bottom; the outer wall of the stirring impeller 28 is rotatably connected to the inner wall of the intelligent water valve 15; a filter element body 16 is clamped on the inner wall of the clean water tank 12; filter holes are provided on the outer wall of the filter tank 29, and there are multiple groups of filter holes, the outer wall of the filter tank 29 is in contact with the inner wall of the filter element body 16, the bottom of the filter tank 29 is fixedly connected to a support frame, and the bottom of the support frame is fixedly connected to the bottom of the inner wall of the clean water tank 12.

[0035] In this embodiment, it is considered that some smaller solid impurities will enter the interior of the device, and sewage treatment usually treats a large amount of sewage, and the filter element is usually replaced every few months or half a year. During this period, a large amount of impurities in the filter element will cause blockage and affect the efficiency and quality of filtration; By setting the intelligent water valve 15, the ionic impurities in the sewage can be purified to the discharge standard before the sewage flows in during sewage treatment. After the water flows into the filter tank 29, the filter holes opened on the filter tank 29 can block smaller impurities to prevent debris from entering the filter element body 16, causing the filter element body 16 to be blocked or the filtering effect to deteriorate, thereby causing the filtered water to fail to meet the discharge standard. The stirring impeller 28 is engaged with the inner shaft so that the inner shaft can drive the stirring impeller 28 to rotate when rotating. At this time, the stirring impeller 28 will stir the sewage and impurities inside to rotate to prevent the impurities from adhering to the filter holes of the filter tank 29 and causing the sewage to be unable to flow out. When there are many smaller impurities in the use environment, the size of the stirring impeller 28 and the filter tank 29 can be increased to accommodate more impurities. Due to the increase in the size of the stirring impeller 28 and the filter tank 29, the size of the filter element body 16 will also be reduced, and the service life of the filter element will also be shortened as the environment becomes more complex. At this time, in order to ensure that the filtered sewage meets the standard, the time for replacing the filter element needs to be shortened, and the impurities inside the filter tank 29 can be cleaned while replacing the filter element.

[0036] Specifically, the filtering mechanism 3 includes a filter plate 31, the outer wall of the filter plate 31 is clamped with the inner wall of the sewage treatment shell 1, the inner wall of the filter plate 31 is provided with through holes, and there are multiple groups of through holes, the inner wall of the filter plate 31 is rotatably connected with a rotating shaft 32, and the inner wall of the filter plate 31 is rotatably connected with the outer wall of the outer rotating shaft; the bottom of the rotating shaft 32 is clamped with the top of the inner rotating shaft, the outer wall of the rotating shaft 32 is fixedly connected with a cutting impeller 33, and there are three groups of cutting impellers 33, and the outer wall of the rotating shaft 32 is fixedly connected with a stirring rod 34, and there are four groups of stirring rods 34.

[0037] In this embodiment, considering that the sewage may contain solid impurities, larger impurities entering the equipment may collide with the equipment, thereby causing damage to the equipment, so the sewage needs to be filtered before sewage treatment; in the prior art, filtering is usually performed directly using a filter net, which may cause the filter net to be blocked during filtering, thereby affecting the sewage treatment efficiency; When sewage enters the equipment, impurities can be filtered out through the setting of the filter plate 31, and the inner rotating shaft can make the rotating shaft 32 rotate in the same direction as the rotating shaft when the inner rotating shaft rotates through the clamping connection between the rotating shaft 32 and the inner rotating shaft. At this time, the rotating shaft 32 will rotate clockwise and drive the cutting impeller 33 and the stirring rod 34 to move clockwise; when sewage enters, the water pressure will impact the cutting impeller 33 and can assist the rotating shaft 32 to rotate, thereby reducing the use of energy; when the stirring rod 34 rotates, it will stir the water flow and form a vortex. At this time, since the water pressure around is higher than the central water pressure, the impurities will flow to the center of the filter plate 31. At this time, even if there are more impurities inside, they will not block all the through holes, and there is no through hole in the central part of the filter plate 31, so the impurities flowing to the center of the filter plate 31 will not affect the filtration efficiency.

[0038] Specifically, the inner wall of the waterproof shell 21 is provided with a first sealing groove, and there are two groups of first sealing grooves, the inner wall of the first sealing groove is fixedly connected with a first sealing ring, the inner wall of one group of first sealing rings is rotatably connected to the inner wall of the inner rotating shaft, and the inner wall of the other group of first sealing rings is rotatably connected to the inner wall of the outer rotating shaft; the inner wall of the filter plate 31 is provided with a second sealing groove, the inner wall of the second sealing groove is fixedly connected with a second sealing ring, and the inner wall of the second sealing ring is rotatably connected to the inner wall of the rotating shaft 32; the inner wall of the smart water valve 15 is provided with a third sealing groove, the inner wall of the third sealing groove is fixedly connected with a third sealing ring, and the inner wall of the third sealing ring is rotatably connected to the inner wall of the stirring impeller 28.

[0039] In this embodiment, the first sealing ring is provided to prevent water from flowing into the interior of the waterproof shell 21, thereby causing damage to the equipment when it encounters water; the second sealing ring is provided to prevent water from entering the interior of the waterproof shell 21 through the gap between the inner rotating shaft and the rotating shaft 32; the third sealing ring is provided to prevent sewage that has not yet reached the standard after internal treatment from entering the interior of the filter tank 29 through the gap, thereby ensuring the quality of sewage treatment and enabling the sewage treatment to meet the treatment standards.

[0040] Specifically, each group of through holes is inclined, and the portion of the through holes that is higher than the top surface of the filter plate 31 is convex.

[0041] In this embodiment, the inclination direction of the through hole is the same as the rotation direction of the rotating shaft 32. When the stirring rod 34 stirs the water flow to make the water flow rotate clockwise, it can flow out quickly, and when it flows clockwise to the bottom, it collides with the counterclockwise rotating purification mechanism 2, which can increase the sewage treatment efficiency. The inclined protrusion design can prevent impurities from getting stuck in the through hole. Since the height of the through hole is increased, when the impurities get stuck in the through hole, they need to lift themselves up a part first, but the water flow stirred by the stirring rod 34 will absorb the impurities, thereby preventing the impurities from blocking the through hole. The protrusion design can be used for stamping dies or retaining stamping residues. Retaining the residue is more economical and does not require additional molds. However, the sharp edges need to be polished before use to prevent scratches. Specifically, a water inlet 13 is fixedly connected to the top of the cover plate 11, and a thread is arranged on the inner wall of the water inlet 13; a through groove is provided on one side of the clean water tank 12, and a water outlet 14 is fixedly connected to the inner wall of the through groove.

[0042] In this embodiment, the sewage can be discharged into the pipe through the setting of the water inlet 13 and connected through the thread. The thread can increase the sealing performance while fixing the pipe, so that the water and gas inside will not flow out from the gap; the treated water can be discharged through the setting of the water outlet 14, and a water pump can be set inside the clean water tank 12, and the drainage pipe can be connected to other equipment for use, storage or direct discharge.

[0043] Specifically, the rotating rod 26 is flattened in the rotating direction and forms an elliptical shape.

[0044] In this embodiment, by making the rotating rod 26 into an oblate shape, the resistance of the water flow can be reduced through the streamlined shape when the rotating rod 26 rotates, thereby reducing energy consumption.

[0045] Specifically, the edge of the cutting impeller 33 is a bevel and has cutting capability.

[0046] In this embodiment, through the design of the cutting impeller 33, some larger impurities in the sewage can be cut by the cutting impeller 33, so that the impurities are smaller when entering the equipment, so as to avoid excessive accumulation of impurities that block the through holes, thereby affecting the sewage treatment efficiency, and collision may occur when the stirring rod 34 stirs the water flow, thereby causing damage to the equipment. At the same time, it can also prevent larger impurities from being affected by the water flow and flowing to the center of the filter plate 31.

[0047] Specifically, the bottom of the cover plate 11 is fixedly connected with a clamping block 17, and there are four groups of clamping blocks 17; the inner wall of the sewage treatment shell 1 is provided with a clamping groove, and there are four groups of clamping grooves; the inner wall of each group of clamping grooves is clamped with the outer wall of the clamping block 17.

[0048] In this embodiment, by setting the snap-fit ​​block 17 and the snap-fit ​​groove, when cleaning is needed, the cover plate 11 can be directly rotated to make the snap-fit ​​block 17 and the snap-fit ​​groove lose their engagement, and the cover plate 11 can be pulled up to open the top of the device. When cleaning, the filter mechanism 3 can be removed as a whole for cleaning, thereby ensuring the simplicity of cleaning.

[0049] When using, First, when sewage enters the device, impurities can be filtered out through the setting of the filter plate 31, and the inner rotating shaft can be connected to the rotating shaft 32 so that the rotating shaft 32 can rotate in the same direction when the inner rotating shaft rotates. At this time, the rotating shaft 32 will rotate clockwise and drive the cutting impeller 33 and the stirring rod 34 to move clockwise; when sewage enters, the water pressure will impact the cutting impeller 33 and can assist the rotating shaft 32 to rotate, thereby reducing the use of energy; when the stirring rod 34 rotates, it will stir the water flow and form a vortex. At this time, since the water pressure around is higher than the central water pressure, the impurities will flow to the center of the filter plate 31. At this time, even if there are more impurities inside, they will not block all the through holes, and there is no through hole in the central part of the filter plate 31, so the impurities flowing to the center of the filter plate 31 will not affect the filtration efficiency; Through the design of the cutting impeller 33, some larger impurities in the sewage can be cut by the cutting impeller 33, so that the impurities are smaller when entering the equipment, so as to avoid excessive accumulation of impurities that block the through holes, thereby affecting the sewage treatment efficiency, and collision may occur when the stirring rod 34 stirs the water flow, thereby causing damage to the equipment. At the same time, it can also prevent larger impurities from being affected by the water flow and flowing to the center of the filter plate 31.

[0050] At the same time, the inclination direction of the through hole is the same as the rotation direction of the rotating shaft 32. When the stirring rod 34 stirs the water flow to make the water flow rotate clockwise, it can flow out quickly, and when it flows clockwise to the bottom, it collides with the counterclockwise rotating purification mechanism 2. At this time, the sewage treatment efficiency can be increased. The inclined protrusion design can prevent impurities from getting stuck in the through hole. Since the height of the through hole is increased, when the impurities are stuck in the through hole, they need to lift themselves up a part first, but the water flow stirred by the stirring rod 34 will absorb the impurities, thereby preventing the impurities from blocking the through hole. The protrusion design can be used as a mold for stamping or retain the residual material of stamping. Retaining the residual material is more economical and does not require additional mold making. However, the sharp edges need to be polished before use to prevent scratches.

[0051] Secondly, when sewage enters, the driving motor 22 is started to rotate the driving gear 23, and the rotation of the driving gear 23 can make the inner shaft gear 24 and the outer shaft gear 25 rotate in different directions. At this time, the inner shaft gear 24 will drive the inner rotating shaft to rotate in the clockwise direction, and the outer shaft gear 25 will drive the outer rotating shaft to rotate in the counterclockwise direction. When the outer rotating shaft rotates, the rotating rod 26 and the adsorption block 27 will be driven to rotate in the same direction; while starting the driving motor 22, the adsorption block 27 and the adsorption plate 18 are energized, and the adsorption block 27 and the adsorption plate 18 are respectively positive and negative poles. By energizing, an electrostatic field can be generated between the adsorption block 27 and the adsorption plate 18, and the charged particles in the sewage will move to the electrode with the opposite charge. At this time, the ions in the sewage can be adsorbed, and the adsorption effect on calcium and magnesium is very good. The effect is better, and the rotation can make the electric adsorption more complete, so that the sewage treatment is purer; when the ions are adsorbed, the water temperature will rise due to the movement of the ions and the resistance of the water to the electric current, and the sewage can be sterilized at high temperature by heating the water; since the sewage is treated by electric adsorption, the same effect as the electrolysis of water will be produced in the process of electric adsorption. The water will be electrolyzed into hydrogen and oxygen, and because of the low density of hydrogen and oxygen, they will float upward to the top of the equipment. At this time, a vent can be opened on the top of the cover plate 11, and the gas can be collected through the vent, which can not only fill the consumables needed in the laboratory, but also because hydrogen is a clean energy and will not pollute the atmosphere when burned, the excess hydrogen can be used as laboratory life gas and can be provided to the laboratory for daily use.

[0052] Then, by setting the intelligent water valve 15, the ionic impurities in the sewage can be purified to the discharge standard before flowing in during sewage treatment. After the water flows into the filter tank 29, the filter holes opened on the filter tank 29 can block smaller impurities to prevent debris from entering the filter element body 16, causing the filter element body 16 to be blocked or the filtering effect to deteriorate, thereby causing the filtered water to fail to meet the discharge standard. The stirring impeller 28 is engaged with the inner shaft so that the inner shaft can drive the stirring impeller 28 to rotate when rotating. At this time, the stirring impeller 28 will stir the sewage and impurities inside to rotate to prevent impurities from adhering to the filter holes of the filter tank 29 and causing the sewage to be unable to flow out. When there are many smaller impurities in the use environment, the size of the stirring impeller 28 and the filter tank 29 can be increased to accommodate more impurities. Due to the increase in the size of the stirring impeller 28 and the filter tank 29, the size of the filter element body 16 will also be reduced, and because the environment is more complicated, the service life of the filter element will also be shortened. At this time, in order to ensure that the filtered sewage meets the standard, the time for replacing the filter element needs to be shortened, and the impurities inside the filter tank 29 can be cleaned while replacing the filter element.

[0053] Finally, when cleaning is required, the adsorption block 27 and the adsorption plate 18 can be powered off and clean water can be added inside. At this time, the ions adsorbed on the surface of the adsorption block 27 and the adsorption plate 18 will fall off due to the loss of the electrostatic field, and be washed away from the surface of the adsorption block 27 and the adsorption plate 18 by the clean water, and can be collected when discharged. Since the sewage is cleaned by physical means, no by-products will be produced, and the discharged water can be collected after cleaning and reused.
