Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and in particular to a high-efficiency magnetic loading coagulation and sedimentation system. Background Art

[0002] In existing technology, magnetic coagulation devices are primarily used in the coagulation and flocculation stage of magnetic coagulation and sedimentation technology. Magnetic coagulation and sedimentation technology introduces magnetic particles into the water purification process of high-efficiency flocculation sedimentation tanks. Through flocculation, attraction, charge adsorption, bridging, and netting, insoluble pollutants such as algae, fine suspended matter, colloids, and bacteria in the water are effectively combined with the fine magnetic powder to form larger and denser magnetic flocs. This enhances the flocculation effect, allowing the capture and aggregation of even smaller pollutants. The flocs settle quickly, resulting in excellent water purification and clear, transparent effluent.

[0003] During the coagulation and flocculation reaction process of the magnetic coagulation sedimentation process, the appropriate amount of magnetic seeds, moderate and efficient stirring and mixing, the size of the magnetic seeds particles, and the uniformity of the magnetic seeds are all factors that affect the mixing, good flocculation reaction and compliance of the effluent with the standards.

[0004] Patent document CN212269551U discloses a magnetic coagulation device, which includes an outer cylinder, an inner cylinder, a driving mechanism, a stirring assembly, a water inlet assembly, a sludge return pipe and a water outlet pipe; the inner cylinder is arranged inside the outer cylinder, and at least one turbulence circle is arranged between the cylinder walls of the outer cylinder and the inner cylinder; the driving mechanism is arranged on the outer cylinder, and the driving mechanism is connected to the transmission shaft that penetrates into the outer cylinder and the inner cylinder; the stirring assembly is arranged in the inner cylinder and connected to the transmission shaft, and the stirring assembly includes at least two blades arranged from top to bottom; the water inlet assembly includes a connected water inlet pipe and a water distribution pipe, the water distribution pipe is arranged in the inner cylinder and is located between the blades; the sludge return pipe is connected to the inner cylinder and is located below the stirring assembly, and the water outlet pipe is connected to the bottom of the inner cylinder.

[0005] However, in actual use, excessive addition of magnetic seeds and differences in the particle size of the magnetic seeds will lead to differences in the flocculation and sedimentation rates of the magnetic seeds. At the same time, the magnetic seeds attract each other and form clumps, resulting in a poor flocculation effect and affecting the effluent standards. Summary of the Invention

By setting a screening mechanism and a sedimentation mechanism, the particle size of the magnetic seeds is selected and the magnetic seeds are added into the reaction container in multiple uniform additions, and the flocculation reaction is carried out in multiple times. To cooperate with the process of multiple additions, the bottom flocs and the upper sewage are isolated each time, so that the bottom mud scraping and the upper stirring are carried out simultaneously, thereby solving the technical problems of poor binding effect between the magnetic powder and the flocs due to the small particle size of the magnetic powder and the attraction and agglomeration of the magnetic seeds due to excessive one-time addition, which affects the flocculation effect.

[0042] The technical solutions in the embodiments of the present invention are clearly and completely described below with reference to the accompanying drawings.

[0043] Example 1

[0044] like Figure 1-13 As shown, a high-efficiency magnetic loading coagulation and sedimentation system includes:

[0045] A reaction mechanism 1, wherein the reaction mechanism 1 is used to provide a reaction vessel for sewage treatment;

[0046] The screening mechanism 2 is arranged above the reaction mechanism 1 and is used to screen and filter the magnetic seeds according to the particle size. The screening mechanism 2 includes a filtering component 21 for screening the magnetic seeds and a delivery component 22 for evenly delivering the filtered magnetic seeds multiple times.

[0047] A sedimentation mechanism 3, which is located inside the reaction mechanism 1 and is used to accelerate the sedimentation of the flocs. The sedimentation mechanism 3 includes an isolation component 31 for isolating the flocs and a moving component 32 for moving the isolation component 31;

[0048] The circulation mechanism 4 includes a plurality of equipment components for cleaning and recirculating the magnetic seeds and performing secondary sedimentation on the sewage.

[0049] In this embodiment, by setting up a screening mechanism 2 and a sedimentation mechanism 3, the particle size of the magnetic seed is controlled so that the particle size of the magnetic seed reaches an appropriate size and is added in multiple times, thereby improving the combination effect of the magnetic seed and the flocs, and the sedimentation of the flocs is accelerated by the sedimentation mechanism 3, and the reaction mechanism 1 is cooperated to achieve acceleration of the sedimentation process.

[0050] In detail, the filter assembly 21 is used to screen out magnetic seeds with suitable particle size, and the magnetic seeds are divided into multiple portions for multiple releases. After each release of the magnetic seeds, the sedimentation mechanism 3 is used to accelerate the sedimentation of the flocs to the bottom of the reaction mechanism 1, and the flocs are isolated from the sewage, and secondary release and floc cleaning are carried out at the same time.

[0051] It should be noted that the amount of sewage treated each time in this system is the capacity of the reaction container. After the sewage treatment is completed, it flows out of the reaction container and is filled with water to be treated. The magnetic seed, coagulant, coagulant aid, etc. are all added in the reaction container.

[0052] It is worth mentioning that through multiple flocculation and sedimentation of the treated water, the sewage can be fully treated and the water quality standard of the effluent can be improved.

[0053] Furthermore, the reaction mechanism 1 includes a reactor 11 containing sewage, a scraper 12 disposed at the bottom of the reactor 11 for scraping off flocs, and a stirring shaft 13 disposed in the middle of the reactor 11 and rotatably connected to the top of the reactor 11 at its upper end.

[0054] In this embodiment, a reaction vessel is provided for sewage treatment by arranging a reactor 11 and a scraper 12 , and flocculation treatment of sewage is achieved by adding magnetic seeds and additives into the reactor 11 .

[0055] In detail, the reactor 11 is provided with a water outlet and a water inlet to control the inflow and outflow of sewage. After the sewage flocculates, it settles to the bottom and is scraped off the reactor 11 by the scraper 12. The rotating shaft rotates to achieve mixing and stirring of the sewage.

[0056] It should be noted that the stirring shaft 13 is rotatably connected to the reactor 11 , and the stirring shaft 13 is driven to rotate by the sedimentation mechanism 3 .

[0057] It is worth mentioning that a discharge ring is provided above the reactor 11 to cooperate with the screening mechanism 2 to discharge the magnetic seeds.

[0058] Furthermore, the filter assembly 21 includes a filter box 211 arranged below the magnetic seed discharge port and having openings on both side walls, an arc-shaped filter plate 212 hinged on one side of the filter box 211, a brush shaft 213 arranged inside the arc-shaped filter plate 212 and rotatably connected to the side wall of the filter box 211, a first motor 214 driving the brush shaft 213 to rotate, a switching plate 215 arranged below the arc-shaped filter plate 212 and rotatably connected to the side wall of the brush shaft 213, and a second motor 216 driving the switching plate 215 to rotate, and the switching plate 215 is connected to the rotating shaft of the arc-shaped filter plate 212 through a transmission belt.

[0059] In this embodiment, by setting up the arc filter plate 212 and the switching plate 215, the magnetic seeds are filtered and the particles with smaller sizes are screened out, thereby controlling the particle size of the magnetic seeds, improving the combination effect of the magnetic seeds and flocs, and ensuring the purification effect.

[0060] In detail, the magnetic seeds fall onto the curved filter plate 212 in the filter box 211, and the first motor 214 drives the brush shaft 213 to rotate, so that the small-particle magnetic seeds pass through the curved filter plate 212 and fall onto the switching plate 215, slide from the switching plate 215 to the opening on one side of the filter box 211 and flow out of the filter box 211, and the larger-particle magnetic seeds remain on the curved filter plate 212, and the second motor 216 drives the switching plate 215 to rotate, so that the switching plate 215 tilts toward the opening on the other side of the filter box 211, and at the same time drives the curved filter plate 212 to rotate through the transmission belt, so that the curved filter plate 212 opens, and the magnetic seeds flow out and flow through the switching plate 215 to the opening on the other side of the filter box 211, completing the separation.

[0061] It should be noted that the arc filter plate 212 consists of two parts, of which the larger part is hinged to one side of the filter box 211 and can rotate. When the larger part rotates downward, the magnetic seeds remaining on the arc filter plate 212 slide down to the switching plate 215.

[0062] It is worth mentioning that when the magnetic seeds fall onto the arc filter plate 212 , the first motor 214 drives the brush shaft 213 to rotate. The rotation of the brush shaft 213 can accelerate the falling speed of the magnetic seeds and prevent the arc filter plate 212 from being blocked.

[0063] Furthermore, the delivery component 22 includes a diverter 221 and a delivery component 222. The diverter 221 includes a fixed plate 2211 arranged below the opening of the filter box 211 and provided with a discharge port, a separating ring 2212 rotatably connected to the upper end face of the fixed plate 2211 and provided with a partition, and a first gear 2214 is arranged on the periphery of the separating ring 2212. The first gear 2214 is engaged with the second gear 2215, and the second gear 2215 is fixedly connected to the output shaft of the third motor 2213.

[0064] In this embodiment, the magnetic seeds are diverted by providing a separation ring 2212 and a fixing plate 2211 , and the magnetic seeds are divided into multiple portions to meet the requirement of multiple injections.

[0065] In detail, the screened magnetic seeds flow out of the filter box 211, and the third motor 2213 drives the separating ring 2212 to rotate. The magnetic seeds fall into the separating ring 2212 and are divided into multiple parts. At the same time, an opening is provided on the fixed plate 2211, and when the separating ring 2212 rotates, the magnetic seeds can fall through the opening of the fixed plate 2211.

[0066] It should be noted that the separation ring 2212 is rotatably connected to the fixed plate 2211 and has no bottom surface, that is, the magnetic powder falls onto the fixed plate 2211, and the separation ring 2212 pushes the magnetic seeds to rotate, thereby achieving separation and falling of the magnetic seeds.

[0067] It is worth mentioning that the separator ring 2212 is provided with a partition, and the magnetic seeds are divided into multiple portions according to the number of partitions. The number of portions of the magnetic seeds, that is, the number of times of injection, can be selected according to the needs.

[0068] Furthermore, the delivery member 222 includes a rotating ring 2221 rotatably connected to the lower end surface of the fixed plate 2211, a fourth motor 2222 driving the rotating ring 2221 to rotate through gear transmission, a feeding pipe 2223 fixedly connected to the rotating ring 2221, a material trough 2224 arranged at the lower end of the feeding pipe 2223 and provided with a drop-out port, a hole plate 2225 arranged at the bottom of the material trough 2224 and rotatably connected to the material trough 2224, and a fifth motor 2226 driving the hole plate 2225 to rotate, a third gear 2226 fixedly connected to the output shaft of the fourth motor, a fourth gear 2227 fixed on the rotating ring, and the third gear 2226 is meshed with the fourth gear 2227.

[0069] In this embodiment, the magnetic seeds are uniformly distributed by providing a trough 2224 and a perforated plate 2225. The trough 2224 can rotate along a discharge ring reserved above the reactor 11, thereby evenly distributing the magnetic seeds into the reactor 11.

[0070] In detail, the magnetic seed enters the feed pipe 2223 through the opening on the fixed plate 2211, passes through the feed pipe 2223 into the material trough 2224, and falls onto the orifice plate 2225. The fourth motor 2222 drives the rotating ring 2221, the feed pipe 2223 and the material trough 2224 to rotate along the discharge ring. The orifice plate 2225 rotates under the drive of the fifth motor 2226. As the orifice plate 2225 rotates, the magnetic seed located above the blanking port passes through the hole on the orifice plate 2225 and the blanking port and falls into the reactor 11.

[0071] It should be noted that the rotating ring 2221 drives the feeding tube 2223 and the material trough 2224 to rotate along the discharge ring. The rotating ring 2221 is provided with an opening connected to the feeding tube 2223. The size of the opening is the same as the opening size on the fixed plate 2211. When the two openings coincide, the magnetic seed can fall from the fixed plate 2211 into the material trough 2224. Therefore, every time the material trough 2224 rotates one circle, the magnetic seed is released once, and then the two openings coincide, and another magnetic seed enters the material trough 2224 to wait for the next release.

[0072] It is worth mentioning that by controlling the rotation of the splitting ring, the magnetic seeds can fall from the opening on the fixed plate 2211, thereby controlling the separated magnetic seeds to be sent into the material trough 2224 before each delivery.

[0073] Furthermore, the isolation assembly 31 includes a fixed ring 311 and multiple groups of sector plates 312 uniformly arranged on the fixed plate 2211. The top sector plate 312 of each group is fixedly connected to the fixed ring 311, while the remaining sector plates 312 are slidably connected to the fixed ring 311 along the track of the fixed ring 311. Each sector plate 312 has a slide groove on its lower end surface and a retaining block 3231 on its upper end surface. The bottom sector plate 312 in each group extends into the fixed ring 311 and is fixedly connected to each other and to the output shaft of the sixth motor 313. Each sector plate 312 is provided with a water permeable hole.

[0074] In this embodiment, multiple sets of fan-shaped plates 312 are provided to isolate the sewage above the reactor 11 from the flocs at the bottom of the reactor 11, thereby achieving simultaneous secondary feeding and magnetic mud cleaning, and avoiding stirring the water body to affect the settled flocs.

[0075] In detail, the sixth motor 313 is started to rotate the lowest fan-shaped plate 312 on each group of fan-shaped plates 312, and the lowest fan-shaped plate 312 drives the upper fan-shaped plates 312 to rotate in turn through the block 3231, thereby opening all the fan-shaped plates 312, and each group of fan-shaped plates 312 cooperates with each other to form a complete cover plate to isolate the flocs.

[0076] It should be noted that the top fan-shaped plate of each group of fan-shaped plates 312 is fixedly connected to the fixed ring 311, and the outer edges of the top fan-shaped plate 312 and the bottom fan-shaped plate 312 are provided with baffles for restricting the movement of the fan-shaped plates 312 so that the bottom single-shot fan-shaped plate 312 can be opened or folded.

[0077] It is worth mentioning that by providing water-permeable holes on the sector plate 312, the sector plate 312 can be water-permeable while preventing flocs from passing through.

[0078] Furthermore, the moving assembly 32 includes a driving member 321 , a telescopic member 322 and an engaging member 323 . The driving member 321 includes a driving shaft 3211 disposed at the center of the reactor 11 and a seventh motor 3212 for driving the driving shaft 3211 to rotate.

[0079] In this embodiment, a seventh motor 3212 is provided to drive the driving shaft 3211 to rotate, and the driving shaft 3211 is used to drive the stirring shaft 13 . The driving shaft 3211 is provided in the middle of the reaction kettle 11 .

[0080] Furthermore, the telescopic member 322 includes a sleeve 3221 fixedly connected to the upper end of the fixing ring 311 and slidably connected to the outside of the driving shaft 3211, and a telescopic cylinder 3222 disposed between the sleeve 3221 and the driving shaft 3211 and fixedly connected to the sleeve 3221.

[0081] In this embodiment, the telescopic cylinder 3222 and the sleeve 3221 are provided to realize the up and down movement of the fixing plate 2211 , and the up and down movement of the fixing plate 2211 can accelerate the settling of the flocs.

[0082] In detail, when the fan-shaped plate 312 is unfolded, the telescopic rod of the telescopic cylinder 3222 is extended, driving the sleeve 3221 and the fixed ring 311 to descend, and the fan-shaped plate 312 is used to accelerate the flocs that have not yet completely settled to the bottom to the bottom. At the same time, through the water-permeable holes on the fan-shaped plate 312, water can pass through the fan-shaped plate 312, thereby achieving rapid sedimentation of the flocs.

[0083] It should be noted that the sleeve 3221 is arranged on the outside of the drive shaft 3211 , and a certain sealing treatment needs to be performed on the sleeve 3221 and the drive shaft 3211 to prevent sewage from invading between the sleeve 3221 and the drive shaft 3211 .

[0084] Furthermore, the engaging member 323 includes a block 3231 rotatably connected to the upper end of the sleeve 3221, a spring 3232 arranged between the inner upper end of the block 3231 and the sleeve 3221, a winding shaft 3233 rotatably connected to the outer shell of the sixth motor 313, a steel wire 3234 connected to the inner lower end of the block 3231 and passing through the sleeve 3221 and wound around the winding shaft 3233, a bevel gear 3235 fixed to the end of the winding shaft 3233, and a bevel gear ring 3236 fixedly connected to the output shaft of the sixth motor 313 and meshing with the bevel gear 3235.

[0085] In this embodiment, by setting the block 3231 and the steel wire 3234, the position of the block 3231 is adjusted, thereby realizing the connection between the drive shaft 3211 and the stirring shaft 13, so that the stirring shaft 13 can start stirring after the fan-shaped plate 312 is unfolded to perform secondary mixing and flocculation.

[0086] In detail, when the fan-shaped plate 312 is unfolded, the bevel gear ring 3236 rotates, and the bevel gear ring 3236 drives the bevel gear 3235 and the winding shaft 3233 to rotate. The winding shaft 3233 tightens the steel wire 3234, causing the block 3231 to rotate. The outer end of the block 3231 contacts the stirring shaft 13, causing the stirring shaft 13 to follow the driving shaft 3211 and start to rotate for stirring.

[0087] It should be noted that the steel wire 3234 passes through the sleeve 3221 and is connected to the block 3231 , so the passage through which the steel wire 3234 passes needs to be sealed.

[0088] It is worth mentioning that, since the sleeve 3221 and the fixed plate 2211 need to move downward, the outermost end of the block 3231 can be free to roll, thereby achieving relative movement of the block 3231 and the stirring shaft 13 without hindering the movement of the sector plate 312 .

[0089] Furthermore, the flow mechanism 4 includes a sludge pump 41 for cooperating with the scraper 12 to carry out magnetic mud flow, a sedimentation tank 42 for secondary static sedimentation of sewage, an inclined pipe 43 arranged inside the sedimentation tank 42 to assist sewage sedimentation, and a high shear machine 44 and a magnetic separator 45 for processing magnetic mud.

[0090] In this embodiment, by providing a sedimentation tank 42 , an inclined pipe 43 , a high shear machine 44 and a magnetic separator 45 , the sewage is subjected to secondary static sedimentation, and the magnetic seeds are recovered by the high shear machine 44 and the magnetic separator 45 .

[0091] In detail, the sludge pump 41 inputs the magnetic mud at the bottom of the reactor 11 into the high shear machine 44 and the magnetic separator 45, separates the magnetic seeds and inputs them into the screening mechanism 2 again. The treated sewage is input into the sedimentation tank 42 and undergoes secondary static sedimentation through the inclined pipe 43.

[0092] Example 2

[0093] Further, if Figure 14 As shown, the process steps of the high-efficiency magnetic loading coagulation sedimentation system are as follows:

[0094] Step 1, screening step, the magnetic seeds fall onto the curved filter plate 212 in the filter box 211, the first motor 214 drives the brush shaft 213 to rotate, so that the small-particle magnetic seeds pass through the curved filter plate 212 and fall onto the switching plate 215, slide from the switching plate 215 to the opening on one side of the filter box 211 and flow out of the filter box 211, and the larger-particle magnetic seeds remain on the curved filter plate 212, the second motor 216 drives the switching plate 215 to rotate, so that the switching plate 215 tilts toward the opening on the other side of the filter box 211, and at the same time drives the curved filter plate 212 to rotate through the transmission belt, so that the curved filter plate 212 opens, and the magnetic seeds flow out and flow through the switching plate 215 to the opening on the other side of the filter box 211 to complete the separation.

[0095] Step 2, the feeding step, the screened magnetic seeds flow out of the filter box 211, the third motor 2213 drives the separation ring 2212 to rotate, and the magnetic seeds fall into the separation ring 2212 and are divided into multiple portions. At the same time, an opening is provided on the fixed plate 2211, and when the separation ring 2212 rotates, the magnetic seeds can fall through the opening of the fixed plate 2211. The magnetic seeds enter the feed pipe 2223 through the opening on the fixed plate 2211, pass through the feed pipe 2223 into the trough 2224, and fall onto the orifice plate 2225. The fourth motor 2222 drives the rotating ring 2221, the feed pipe 2223 and the trough 2224 to rotate along the discharge ring. The orifice plate 2225 rotates under the drive of the fifth motor 2226. As the orifice plate 2225 rotates, the magnetic seeds located above the drop opening pass through the holes on the orifice plate 2225 and the drop opening and fall into the reactor 11.

[0096] Step three, the sedimentation step, the sixth motor 313 is started, so that the lowest fan-shaped plate 312 on each group of fan-shaped plates 312 rotates, and the lowest fan-shaped plate 312 drives the upper fan-shaped plate 312 to rotate in turn through the block 3231, so that all the fan-shaped plates 312 are opened, and each group of fan-shaped plates 312 cooperates with each other to form a complete cover plate, and the bevel gear ring 3236 rotates, and the bevel gear ring 3236 drives the bevel gear 3235 and the winding shaft 3233 to rotate, and the winding shaft 3233 tightens the steel wire 3234 to rotate the block 3231, and the outer end of the block 3231 contacts the stirring shaft 13, so that the stirring shaft 13 starts to rotate following the drive shaft 3211 for stirring.

[0097] After the stirring is completed, the fan-shaped plates 312 are overlapped. When the flocs are settled to the position below the fan-shaped plates 312, the fan-shaped plates 312 are unfolded again, and the telescopic rod of the retraction cylinder is extended, driving the sleeve 3221 and the fixed ring 311 to descend. The fan-shaped plates 312 are used to accelerate the flocs that have not yet completely settled to the bottom to the bottom. At the same time, through the water-permeable holes on the fan-shaped plates 312, water can pass through the fan-shaped plates 312, realizing the rapid settlement of the flocs and performing secondary feeding at the same time.
