Description

Technical Field

[0001] This invention relates to the field of seawater purification technology, specifically to a seawater purification and filtration device. Background Technology

[0002] Seawater purification refers to the entire process of pre-treating raw seawater through flocculation sedimentation, multi-stage filtration, deep desalination, and disinfection post-treatment, thoroughly separating suspended solids, colloidal organic matter, harmful microorganisms, and dissolved inorganic salt ions in the water, and transforming high-salinity seawater into usable water resources that meet standards. It includes both purification pretreatment for impurity removal and the core desalination process for salt removal.

[0003] The existing technology still has the following problems:

[0004] 1. Traditional seawater mixing devices rely solely on a single central stirring paddle to agitate the water. This results in significant differences in the flowability of seawater between the inner wall, upper layer, and lower layer of the processing tank. After the liquid polyaluminum chloride (PAC) agent is added, stratification can easily occur, with some areas having excessively high concentrations and others having insufficient concentrations. Seawater colloids and fine suspended solids cannot fully react with the flocculant, leading to poor floc formation. A large number of tiny impurities cannot settle, resulting in incomplete pretreatment and purification, which directly increases the load on the downstream filtration unit. Furthermore, traditional mixing structures lack interlocking flow-disrupting components and rely solely on central stirring to create unidirectional water flow. This causes water to stagnate around the tank walls for extended periods, resulting in low agent mixing efficiency.

[0005] 2. Conventional seawater filter belts rely solely on a single-sided scraper to statically remove flocculated particles. During the filtration process, the flocculated impurities adhere tightly to the inside of the filter belt pores, and a single scraping is insufficient to completely clean them. The equipment lacks an automatic dust-removing structure, resulting in continuous blockage of the filter belt pores and a rapid decrease in water flow. Frequent shutdowns are required to disassemble the equipment for manual washing and filter replacement, making it impossible to achieve continuous 24-hour seawater purification operations. This leads to low processing efficiency and high maintenance labor costs.

[0006] Therefore, a seawater purification and filtration device is proposed. Summary of the Invention

[0007] The purpose of this invention is to provide a seawater purification and filtration device to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a seawater purification and filtration device, comprising a base, a sedimentation mechanism being provided at the top of the base, and a filtration mechanism being provided at the bottom of the sedimentation mechanism;

[0009] The sedimentation mechanism includes a processing barrel, a drive groove, a sliding plate, a limiting block, a second fixing plate, and a second shaft. The processing barrel is fixedly connected to the top of the base. The drive groove is arranged in a circular array and fixedly connected to the inner wall of the processing barrel. The sliding plate is slidably connected to the inner wall of the middle part of the drive groove. The limiting block is symmetrically fixedly connected to the inner wall of the top of the sliding plate. The second fixing plate is fixedly connected to the end of the sliding plate away from the limiting block. The second shaft is rotatably connected to the inner walls of both ends of the second fixing plate.

[0010] The filtration mechanism includes a first groove plate, a connecting plate, a third shaft, a sleeve rod, an annular rod, and a protective groove plate. The first groove plate is fixedly connected to the inner wall of the base. The connecting plate is fixedly connected to the bottom side wall of the first groove plate. The third shaft is fixedly connected to the side wall of the connecting plate. The sleeve rod is sleeved on the outer wall of the third shaft. The annular rod is fixedly connected to both ends of the sleeve rod. The protective groove plate is fixedly connected to the side wall of the annular rod.

[0011] Preferably, the sedimentation mechanism further includes a discharge valve fixedly connected to the inner wall of the bottom end of the processing barrel, a dosing metering pump fixedly connected to the inner wall of the top end of the processing barrel, a drive motor fixedly connected to the upper surface of the processing barrel, a water pump fixedly connected to the side wall of the processing barrel, a shaft rotatably connected to the inner wall of the top end of the processing barrel, a stirring paddle symmetrically fixedly connected to the outer wall of the shaft, a star-shaped double-sided groove plate fixedly connected to the outer wall of the middle part of the shaft, an adjusting frame symmetrically rotatably connected to the inner wall of the drive groove, a lever plate fixedly connected to the outer wall of the adjusting frame near the star-shaped double-sided groove plate, a fixing plate symmetrically fixedly connected to the outer wall of the adjusting frame away from the lever plate, a sliding groove 1 penetrating the inner wall of the fixing plate, and an arc-shaped plate fixedly connected to the outer wall of the fixing plate away from the star-shaped double-sided groove plate.

[0012] Preferably, the filtration mechanism further includes a second drive motor fixedly connected to the outer wall of the base, a collection tank fixedly connected to the bottom side wall of the first trough plate, a transmission wheel symmetrically rotatably connected to the inner walls of both ends of the base, a filter belt drively connected between the two transmission wheels, a groove penetrating the inner wall of the connecting plate, a mounting plate symmetrically fixedly connected to the side wall of the connecting plate, scrapers arranged in a linear array and fixedly connected to the inner wall of the mounting plate, activated carbon filter plates symmetrically fixedly connected to the outer walls of both sides of the middle part of the connecting plate, and a gear symmetrically fixedly connected to the outer walls of both ends of one of the transmission wheels.

[0013] Preferably, the filtration mechanism further includes a rubber plate arranged in a ring array and fixedly connected to the outer wall of the collection tank; a gear two fixedly connected to the outer wall of the protective trough plate on the side away from the rubber plate; a sliding groove two arranged in a ring array and opened on the outer wall of the ring rod; a limiting rod slidably connected inside the sliding groove two; an elastic element hinged to the outer end of the limiting rod; magnetic grooves arranged in a ring array and opened on the outer walls of both ends of the shaft three; a discharge valve two fixedly connected to the inner wall of the bottom end of the base; and a toothed belt meshing between the gear two and the gear one.

[0014] Preferably, the top of the water pump is fixedly connected to the inside of the processing barrel, and the drive end of the first drive motor is fixedly connected to the first shaft.

[0015] Preferably, the limiting block is slidably connected to the outer wall of the star-shaped double-sided groove plate, and the two ends of the second shaft are slidably connected to the inside of the first groove;

[0016] The star-shaped double-sided groove plate rotates continuously with the shaft, and the outer wall is fitted with a limiting block. During the rotation, the limiting block is continuously pushed and pulled, which drives the slide plate to reciprocate within the drive groove.

[0017] The two ends of the shaft slide into the groove of the fixed plate. When the slide plate moves horizontally, it drives the adjustment frame to rotate back and forth through the fixed plate and the shaft, so as to realize the cyclic disturbance of the water by the plate. The linkage stirring structure without additional power is achieved by sliding cooperation.

[0018] Preferably, both the drive motor and the water pump are electrically connected to an external controller.

[0019] Preferably, the discharge valve is fixedly connected to the inside of the trough plate, the filter belt is slidably connected to the inside of the groove, the top of the scraper is tightly fitted to the lower surface of the filter belt, the end of the elastic element away from the limit rod is fixedly connected to the protective trough plate, and the drive motor is electrically connected to the external controller.

[0020] The discharge valve at the bottom of the processing tank is connected to the lower trough plate, allowing the flocculated seawater and flocs to be directly discharged into the filtration mechanism, achieving seamless connection between sedimentation and filtration processes.

[0021] The connecting plate has grooves, and the filter belt passes through the grooves to limit the running trajectory of the filter belt and prevent it from deviating.

[0022] The scraper on the mounting plate is in close contact with the lower surface of the filter belt, and automatically scrapes away the flocculated impurities trapped by the filter belt as the filter belt moves;

[0023] One end of the elastic element is fixed to the protective groove plate, and the other end is hinged to the limiting rod. The limiting rod is pulled away from the magnetic groove by the elastic force, so as to realize the intermittent accelerated hammering action of the ring rod.

[0024] Preferably, the upper surface of the connecting plate is attached to the top and lower surface of the filter yarn belt, an installation groove is provided on the top inner wall of the base, the connecting plate is fixedly connected to the inner wall of the mounting groove of the base, and a reaction tank is formed between the middle part of the connecting plate and the mounting groove, and the top of the discharge valve two is connected to the reaction tank.

[0025] The top surface of the connecting plate supports the filter belt, ensuring that the seawater is evenly stressed and filtered thoroughly when passing through the filter belt.

[0026] The connecting plate is fixed in the mounting groove of the base. The connecting plate and the base enclose a sealed reaction tank. Seawater flows into the reaction tank after passing through the filter belt. The activated carbon filter plate in the tank adsorbs the residual PAC agent. The purified water is finally discharged and collected from the bottom discharge valve.

[0027] Preferably, a magnetic block is provided at the end of the limiting rod away from the elastic element, the magnetism of the magnetic groove is opposite to that of the side of the magnetic block that is close to it, and the collection tank and the first tank plate are fixedly connected by a screw.

[0028] The magnetic block at the end of the limiting rod and the magnetic groove on the shaft are attracted by opposite poles, and the ring rod is attracted and fixed under normal conditions.

[0029] The protective groove plate rotates continuously, stretching the elastic element. When the elastic force exceeds the magnetic attraction force, the limit rod disengages from the magnetic groove, the ring rod accelerates instantly, and the rubber plate quickly strikes the filter belt, achieving automatic dirt removal from the filter belt.

[0030] Compared with the prior art, the beneficial effects of the present invention are:

[0031] 1. Through the sedimentation mechanism, the drive motor drives the shaft and the stirring paddle to rotate and stir the liquid polyaluminum chloride (PAC) and seawater. At the same time, the star-shaped double-sided groove plate on the shaft moves back and forth in conjunction with the limiting block, sliding plate and arc plate, and the adjusting frame and the dial plate rotate back and forth to disturb the water body. This disrupts the flow direction of the seawater inside the processing tank in all directions, and promotes the full circulation and mixing of the water in the top, middle and surrounding areas of the tank. This solves the defects of uneven concentration and insufficient mixing of flocculant in some areas, greatly improves the flocculation and sedimentation effect of liquid polyaluminum chloride (PAC) on seawater colloids and suspended solids, and enhances the pretreatment and purification capacity of seawater.

[0032] 2. Through the filtration mechanism, the drive motor 2 drives the conveyor wheel and filter belt to continuously transport the filtered flocculent sediment; gear 1 drives gear 2 and the ring rod to rotate synchronously via the toothed belt. Relying on the cooperation of magnetic groove, limit rod and elastic element, the ring rod is intermittently accelerated to rotate, which drives the rubber plate to repeatedly hit the filter belt. With the help of the scraper on the inner side of the mounting plate, the flocculent impurities on the surface of the filter belt are scraped off. At the same time, the activated carbon filter plate can adsorb the unprecipitated residual polyaluminum chloride agent in the water, realizing the dual effect of online self-cleaning of the filter belt and secondary adsorption and purification of the agent. This avoids filter belt clogging and filtration efficiency reduction, reduces the frequency of manual disassembly and cleaning, and improves the stability of continuous seawater filtration and purification.

[0049] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0050] Example 1

[0051] Please see Figures 1 to 12 The first embodiment of the present invention provides a seawater purification and filtration device, which includes a base 101, a sedimentation mechanism 200 at the top of the base 101, and a filtration mechanism 300 at the bottom of the sedimentation mechanism 200.

[0052] Example 2

[0053] Reference Figures 1 to 7This is the second embodiment of the present invention. This embodiment differs from the first embodiment in that: the sedimentation mechanism 200 includes a processing barrel 201, a drive groove 209, a slide plate 214, a limiting block 215, a second fixing plate 216, and a second shaft 217. The processing barrel 201 is fixedly connected to the top of the base 101. The drive groove 209 is arranged in a circular array and fixedly connected to the inner wall of the processing barrel 201. The slide plate 214 is slidably connected to the inner wall of the middle part of the drive groove 209. The limiting block 215 is symmetrically fixedly connected to the inner wall of the top of the slide plate 214. The second fixing plate 216 is fixedly connected to the end of the slide plate 214 away from the limiting block 215. The second shaft 217 is rotatably connected to the inner walls of both ends of the second fixing plate 216.

[0054] Furthermore, the sedimentation mechanism 200 also includes a discharge valve 202 fixedly connected to the inner wall of the bottom end of the processing tank 201, a dosing metering pump 203 fixedly connected to the inner wall of the top end of the processing tank 201, a drive motor 204 fixedly connected to the upper surface of the processing tank 201, and a water pump 205 fixedly connected to the side wall of the processing tank 201. Both the drive motor 204 and the water pump 205 are electrically connected to an external controller. The top end of the water pump 205 is fixedly connected to the interior of the processing tank 201 and rotatably connected to a shaft 206 on the inner wall of the top end of the processing tank 201. The drive end of the drive motor 204 is fixedly connected to the shaft 206 and symmetrically fixedly connected to an agitator on the outer wall of the shaft 206. The components include: a mixing paddle 207; a star-shaped double-sided groove plate 208 fixedly connected to the outer wall of the middle part of the shaft 206; a limiting block 215 slidably connected to the outer wall of the star-shaped double-sided groove plate 208 and symmetrically rotatably connected to the inner wall of the drive groove 209; a lever plate 211 fixedly connected to the outer wall of the adjusting frame 210 near the star-shaped double-sided groove plate 208; a fixing plate 212 symmetrically fixedly connected to the outer wall of the adjusting frame 210 away from the lever plate 211; a sliding groove 213 penetrating the inner wall of the fixing plate 212; two ends of the shaft 217 slidably connected to the inside of the sliding groove 213; and an arc plate 218 fixedly connected to the outer wall of the fixing plate 216 away from the star-shaped double-sided groove plate 208.

[0055] It should be noted that the dosing metering pump 203 is connected to an external device for transporting liquid polyaluminum chloride (PAC), and the water pump 205 is connected to an external device for storing seawater.

[0056] During use: First, the operator connects the water pump 205 to the external seawater storage device, so that the operator controls the water pump 205 to start discharging seawater into the processing tank 201 through the external controller. Then, the operator controls the drive motor 204 to start working through the external controller, so that the drive motor 204 drives the shaft 206 to rotate inside the processing tank 201. During the rotation of the shaft 206, the external device for conveying liquid polyaluminum chloride (PAC) dispenses a quantitative amount into the processing tank 201 through the metering pump 203.

[0057] During the rotation of shaft 206, shaft 206 drives the agitator 207 to rotate, causing the agitator 207 to stir the mixed solution inside the processing tank 201. Simultaneously, shaft 206 drives the star-shaped double-sided groove plate 208 to rotate synchronously. As the star-shaped double-sided groove plate 208 rotates, it causes the connecting limiting block 215 to repeatedly move along the outer wall of the star-shaped double-sided groove plate 208 towards the side closer to shaft 206. This causes the limiting block 215 to cause the sliding plate 214 to slide back and forth inside the drive groove 209. As the sliding plate 214 moves towards the side closer to shaft 206, it causes the fixing plate 216 to move synchronously, causing the fixing plate 216 to drive the two rotating fixed plates 224 at both ends... 16. The synchronous movement causes the fixed plate 216 to slide towards the side closer to the adjusting frame 210 inside the slide groove 213. At the same time, the slide groove 213 abuts against the slide groove 213, causing the slide groove 213 to drive the adjusting frame 210 to flip upward on the inner wall of the drive groove 209. This causes the adjusting frame 210 to drive the top of the dial plate 211 to flip upward away from the shaft 206. When the slide plate 214 slides away from the shaft 206 inside the drive groove 209, the adjusting frame 210 drives the top of the dial plate 211 to start flipping downward towards the side closer to the shaft 206. This repeated flipping of the dial plate 211 disrupts the flow direction of the mixed solution and increases the flow area of ​​the mixed solution at the top, middle and bottom of the processing tank 201.

[0058] Simultaneously, during the movement of the slide plate 214, the slide plate 214 drives the arc plate 218 to move laterally back and forth inside the processing barrel 201. This causes the arc plate 218 to drive the mixed solution around the inner wall of the processing barrel 201 to flow towards one side of the shaft 206, thereby increasing the fluidity of the mixed solution around the inner wall of the processing barrel 201. This, in turn, improves the mixing effect between liquid polyaluminum chloride (PAC) and seawater, and enhances the flocculation effect of liquid PAC on seawater, ultimately improving the purification effect of liquid PAC on seawater.

[0059] After the mixing is completed, the operator opens the discharge valve 202, allowing the mixed solution and precipitate inside the processing tank 201 to enter the interior of the tank plate 301.

[0060] Through the sedimentation mechanism 200, the drive motor 204 drives the shaft 206 and the stirring paddle 207 to rotate and stir the liquid polyaluminum chloride (PAC) and seawater. At the same time, the star-shaped double-sided groove plate 208 on the shaft 206 moves back and forth in conjunction with the limiting block 215, the sliding plate 214, and the arc plate 218. In conjunction with the adjusting frame 210 and the lever 211, the water body is disturbed by repeated flipping. The flow direction of seawater inside the processing tank 201 is disrupted in all directions, which promotes the full circulation and mixing of water in the top, middle and surrounding areas of the tank. This solves the defects of uneven local concentration and insufficient mixing of flocculant, greatly improves the flocculation and sedimentation effect of liquid polyaluminum chloride (PAC) on seawater colloids and suspended solids, and enhances the pretreatment and purification capacity of seawater.

[0061] Example 3

[0062] Reference Figures 7 to 12 This is the third embodiment of the present invention, which differs from the second embodiment in that: the filter mechanism 300 includes a first groove plate 301, a connecting plate 306, a third shaft 312, a sleeve rod 313, an annular rod 315, and a protective groove plate 316. The first groove plate 301 is fixedly connected to the inner wall of the base 101, the discharge valve 202 is fixedly connected to the inside of the first groove plate 301, the connecting plate 306 is fixedly connected to the bottom side wall of the first groove plate 301, the third shaft 312 is fixedly connected to the side wall of the connecting plate 306, the sleeve rod 313 is sleeved on the outer wall of the third shaft 312, the annular rod 315 is fixedly connected to both ends of the sleeve rod 313, and the protective groove plate 316 is fixedly connected to the side wall of the annular rod 315.

[0063] Furthermore, the filtration mechanism 300 also includes a second drive motor 302 fixedly connected to the outer wall of the base 101, the second drive motor 302 being electrically connected to an external controller, a collection tank 303 fixedly connected to the bottom side wall of the first trough plate 301, the collection tank 303 being fixedly connected to the first trough plate 301 via screws, transmission wheels 304 symmetrically rotatably connected to the inner walls at both ends of the base 101, and a filter belt 305 being driven between the two transmission wheels 304. The upper surface of the connecting plate 306 and the top and lower surfaces of the filter belt 305 are connected. The connecting plate 306 has a groove 307 that fits and penetrates the inner wall of the connecting plate 306. The filter yarn 305 is slidably connected to the inside of the groove 307. The mounting plate 308 is symmetrically fixed to the side wall of the connecting plate 306. The scraper 309 is arranged in a linear array and fixed to the inner wall of the mounting plate 308. The top of the scraper 309 is tightly fitted to the lower surface of the filter yarn 305. The activated carbon filter plate 310 is symmetrically fixed to the outer walls of the two sides of the middle part of the connecting plate 306. The gear 311 is symmetrically fixed to the outer walls of both ends of one of the conveyor wheels 304.

[0064] Furthermore, the filtration mechanism 300 also includes rubber plates 314 arranged in a ring array and fixedly connected to the outer wall of the collection tank 303; gears 317 fixedly connected to the outer wall of the protective trough plate 316 on the side away from the rubber plates 314; sliding grooves 318 arranged in a ring array and opened on the outer wall of the ring rod 315; a limiting rod 319 slidably connected inside the sliding groove 318; and an elastic element 320 hinged to the outer end of the limiting rod 319. A magnetic block is provided at the end of the limiting rod 319 away from the elastic element 320, and the end of the elastic element 320 away from the limiting rod 319 is connected to the protective trough plate 316. A magnetic groove 321 is fixedly connected and arranged in a ring array on the outer wall of both ends of the shaft 312. The magnetic properties of the magnetic groove 321 are opposite to those of the magnetic blocks on the side that are close to each other. A discharge valve 322 is fixedly connected to the inner wall of the bottom end of the base 101. An installation groove is provided on the inner wall of the top of the base 101. A connecting plate 306 is fixedly connected to the inner wall of the installation groove of the base 101. The middle part of the connecting plate 306 and the installation groove form a reaction groove. The top of the discharge valve 322 communicates with the reaction groove. A toothed belt 323 is meshed between the gear 2 317 and the gear 1 311.

[0065] During use: Before the discharge valve 202 is opened, the operator controls the drive motor 302 to start working through the external controller, so that the drive motor 302 drives the transmission wheel 304 to rotate on the inner wall of the base 101. The transmission wheel 304 drives the filter belt 305 to move slowly towards the side closer to the drive motor 302. When the mixed solution and filter enter the interior of the tank plate 301, the mixed solution enters the reaction tank between the connecting plate 306 and the base 101 through the filter belt 305. The residual liquid polyaluminum chloride (PAC) in the mixed solution is initially absorbed by the activated carbon filter plate 310. Then, the seawater in the reaction tank is discharged and collected through the discharge valve 322.

[0066] Flocculents in the mixed solution are filtered through the filter belt 305 and carried into the mounting plate 308 by the filter belt 305. They are then repeatedly scraped away by the scraper 309 fixedly connected inside the mounting plate 308. Simultaneously, as the conveyor wheel 304 rotates, it drives gear one 311 to rotate. Gear one 311, through the toothed belt 323, drives gear two 317 to rotate synchronously. Gear two 317 then drives the protective groove plate 316 to rotate synchronously. This causes the protective groove plate 316 to pull the elastic element 320 to extend. During the extension of the elastic element 320, the elastic force gradually increases. When the elasticity of the elastic element 320 exceeds the magnetic attraction between the limiting rod 319 and the magnetic groove 321, the elastic element 320 pulls the limiting rod 319 to slide outwards inside the magnetic groove 321 and the sliding groove 318. When the limiting rod 319 disengages from the magnetic groove 321, the limiting rod 319 is then subjected to the elastic force of the elastic element 320. Under the action of the ring rod 315, the limiting rod 319 rotates to the side of the adjacent magnetic groove 321. During this process, the elastic force of the elastic element 320 gradually decreases, causing the limiting rod 319 to be magnetically attracted to the adjacent magnetic groove 321 again. As the protective groove plate 316 continues to rotate, the ring rod 315 is driven to accelerate again. This results in the ring rod 315 being driven to accelerate intermittently during the uniform rotation of the protective groove plate 316. Consequently, the ring rod 315 drives the sleeve rod 313 to rotate intermittently on the outer wall of the shaft rod 312. This causes the sleeve rod 313 to drive the rubber plate 314 to repeatedly strike the part of the filter belt 305 located inside the mounting plate 308. As the rubber plate 314 repeatedly strikes the filter belt 305, the adhering substances on the outer surface of the filter belt 305 are detached or the adhesion effect is reduced, thereby improving the scraping effect of the scraper 309 on the filtered material.

[0067] Through the filtration mechanism 300, the second drive motor 302 drives the conveyor wheel 304 and the filter belt 305 to continuously transport the filtered flocculent sediment. The first gear 311 drives the second gear 317 and the ring rod 315 to rotate synchronously via the toothed belt 323. The ring rod 315 is intermittently accelerated to rotate by the cooperation of the magnetic groove 321, the limiting rod 319, and the elastic element 320, which drives the rubber plate 314 to repeatedly beat the filter belt 305. With the help of the scraper 309 on the inner side of the mounting plate 308, the flocculent impurities on the surface of the filter belt are scraped off. At the same time, the activated carbon filter plate 310 can adsorb the unprecipitated residual polyaluminum chloride agent in the water, realizing the dual effect of online self-cleaning of the filter belt 305 and secondary adsorption and purification of the agent. This avoids filter belt clogging and filtration efficiency reduction, reduces the frequency of manual disassembly and cleaning, and improves the stability of continuous seawater filtration and purification.
