Description

Technical Field

[0001] The invention relates to the technical field of waste liquid treatment, and in particular to a laboratory waste liquid treatment device. Background Art

[0002] Laboratory wastewater may contain heavy metal ions or metal particles such as mercury, lead, cadmium, chromium, and silver. When treating these metal particles, magnets can be used to remove ferromagnetic metal particles from the wastewater. For example, wastewater containing iron powder can be quickly separated using magnets. Flocculants are also added to aggregate tiny suspended particles or colloids into larger particles for subsequent filtration or separation.

[0003] The patent document with announcement number CN118545807B discloses a wastewater treatment device for dyeing straw and willow products, including a shell and a dosing shaft rotatably arranged on the top of the shell. The outer edge surface of the dosing shaft is provided with multiple groups of electrostatic adsorption components connected to an external electrostatic generator in a circular array. One group of the electrostatic adsorption components forms a disc-shaped structure, and multiple groups of the electrostatic adsorption components are connected to the dosing shaft.

[0004] The above-mentioned prior art applies static electricity to multiple groups of electrostatic adsorption components through an external electrostatic generator, thereby generating an electrostatic adsorption phenomenon, adsorbing impurities, suspended matter and heavy metal ions in the sewage on the surface of the multiple groups of electrostatic adsorption components, and coordinating the rotating gaps between the multiple partitions to narrow the gap between the sewage and a group of electrostatic adsorption components, thereby coordinating with the stirring mechanism to stir the sewage, realizing the circulation of sewage between the multiple rotating gaps, and then coordinating with the scraping and unloading components to scrape the impurities attached to the electrostatic adsorption components into the multiple partitions, completing the cleaning of the sewage.

[0005] However, this solution also presents the following issues: When adsorbing impurities, some larger metal impurity particles will settle to the bottom of the shell, making it difficult to clean up these settled impurities. Furthermore, if wastewater requires flocculation treatment, the agitation mechanism will agitate the wastewater, breaking up the flocculated impurities, affecting the flocculation effect and subsequent separation operations, and reducing the treatment efficiency. Summary of the Invention

[0006] The present invention provides a laboratory waste liquid treatment device, which aims to solve the problems in the related art that it is inconvenient to clean large metal particles deposited at the bottom of the shell and the stirring mechanism easily breaks up flocculated impurities when stirring the sewage, thereby affecting the treatment effect of the sewage.

[0007] The laboratory waste liquid treatment device of the present invention comprises a bracket, a cylinder is provided on the bracket, and a cleaning component and a driving component are provided on the cylinder;

[0008] The cylinder body includes: an annular cylinder rotatably matched with the bracket, and an intermediate plate rotatably matched with both ends of the annular cylinder, wherein the intermediate plate and the annular cylinder together form a cavity for placing waste liquid;

[0009] The cleaning assembly includes: a magnetic ring sleeved on the outside of the annular cylinder, a collection frame located inside the annular cylinder and connected to the middle plate, and a scraper located between the collection frame and the annular cylinder, wherein the upper end of the scraper is inclined in a clockwise direction and abuts against the inner wall of the annular cylinder;

[0010] An opening is provided on the top of the magnetic ring, and the collection frame corresponds to the opening;

[0011] The driving assembly is connected to the annular cylinder to drive the annular cylinder to rotate around the middle plate;

[0012] The magnetic ring attracts the metal impurities at the bottom of the annular cylinder and makes them stick to the inner wall of the annular cylinder. The annular cylinder rotates counterclockwise around the middle plate, driving the impurities to separate from the waste liquid. After the impurities move to the top of the collection frame, they escape from the adsorption range of the magnetic ring and fall into the collection frame. Then the scraper scrapes off the remaining impurities on the annular cylinder and guides them into the collection frame.

[0013] Waste liquid is added into the cavity for treatment. When the precipitated metal impurity particles need to be treated, the driving component drives the annular cylinder to rotate counterclockwise around the middle plate, the middle plate remains stationary, and the magnetic ring adsorbs the metal impurities at the bottom of the annular cylinder, so that the metal impurities stick to the annular cylinder and can rotate with the annular cylinder. As the annular cylinder rotates, the metal impurities are separated from the waste liquid and rotated toward the collection frame. After the metal impurities move to the top of the collection frame, which is the opening of the magnetic ring, they are out of the adsorption range of the magnetic ring and fall into the collection frame. As the annular cylinder continues to rotate, the scraper scrapes off the remaining impurities and collects them through the collection frame. During the collection process, the annular cylinder rotates to remove the impurities at its bottom, and at the same time, the disturbance to the flocs is small, so as to carry out subsequent separation treatment, etc., thereby improving the treatment effect of the waste liquid.

[0014] Preferably, the scraper is rotatably connected to the collecting frame, and a torsion spring is installed at the connection so that the upper end of the scraper is close to the inner wall of the annular cylinder. A connecting rod coaxial with the rotating shaft of the scraper is provided on the collecting frame. The connecting rod passes through the middle plate and extends to the outside of the cavity. A baffle rod is provided on the side of the connecting rod, and an extension part is provided on the annular cylinder. The extension part is sleeved on the outside of the baffle rod. A plurality of levers are provided circumferentially on the extension part. When the lever rotates and cooperates with the baffle rod, it drives the collecting frame to swing. A drainage hole is provided on the side of the collecting frame away from the scraper.

[0015] The extension part rotates with the annular cylinder, driving the multiple shifting rods to cooperate with the blocking rods in sequence, driving the collection frame to swing back and forth, so as to discharge the water contained in the impurities through the drainage holes.

[0016] Preferably, a clearance groove is opened on the side of the middle plate, and the side of the block rod extends into the clearance groove. A plurality of protrusions are provided in the clearance groove. When the shift rod drives the block rod to rotate, the block rod passes through the plurality of protrusions in turn to drive the collection frame to vibrate. After the shift rod is separated from the block rod, the block rod rotates until it abuts against the inner wall of the clearance groove.

[0017] When the blocking rod rotates, it passes through the protrusion, causing the placement frame to vibrate so as to discharge water from the impurities.

[0018] Preferably, a push plate is slidably installed in the collection frame, and the end of the push plate facing away from the collection frame abuts against the inner side of the scraper. A spring member connected to the collection frame is provided on the push plate, and the spring member drives the push plate to move toward the direction of the scraper shaft, and the upper end of the push plate slides and abuts against the inner side of the scraper.

[0019] When the collecting frame rotates toward the scraper, the distance between the collecting frame and the scraper decreases, and the push plate moves under the action of the scraper, while scraping off the impurities adhering to the scraper, thereby cleaning the scraper.

[0020] Preferably, a debris removal component is provided in the annular cylinder, an outlet 1 is provided below the collecting frame, and a control component for controlling the closing of the outlet 1 is provided on the collecting frame. The debris removal component includes: a debris removal pipe, a guide frame, a spiral piece, and a power piece. The debris removal pipe is coaxially rotatable and arranged in the annular cylinder. The debris removal pipe is fixedly connected to the bracket. The guide frame is arranged in a vertical direction. The lower end of the guide frame is connected to the inside of the debris removal pipe, and the upper end is located below the outlet 1. An outlet 2 is provided on the side of the debris removal pipe, and the outlet 2 is located outside the annular cylinder. The spiral piece is rotatably assembled in the debris removal pipe, and the power piece is arranged on the debris removal pipe, and the output end of the power piece is connected to the spiral piece.

[0021] The control component opens outlet 1, and the impurities in the collection frame enter the impurity discharge pipe through the guide frame. Then the power component drives the spiral piece to rotate, and the impurities in the impurity discharge pipe are discharged through outlet 2.

[0022] Preferably, the control assembly includes a slide plate, a push rod, and a second spring member. The slide plate is slidably assembled at the bottom of the collection frame to control the closing of outlet one. The push rod is arranged in the collection frame and connected to the slide plate. The second spring member connects the slide plate and the collection frame. The second spring member is used to drive the slide plate to move toward the push plate and close outlet one. A control rod is provided on the extension portion. The length of the control rod is greater than the length of the dial rod. When the control rod cooperates with the barrier rod, it drives the push plate to cooperate with the push rod and drives the push rod to move. The movement of the push rod drives the slide plate to move to open outlet one.

[0023] When the control rod cooperates with the blocking rod, the rotation angle of the placement frame increases, the push plate moves to abut against the push rod, and the push rod drives the slide plate to move, thereby controlling the opening of the outlet 1. After the push plate is separated from the push rod, the elastic member 2 drives the slide plate to move to the initial position, closing the outlet 1 again.

[0024] Preferably, a mounting portion is provided on the side of the collecting frame facing away from the scraper, a drainage hole is provided on the mounting portion, a placement cavity for placing liquid medicine for treating waste liquid is provided in the mounting portion, and an outlet three communicating with the placement cavity is provided on the mounting portion.

[0025] When the placing frame swings, the placing cavity is driven to swing so as to spill out the liquid medicine in the placing cavity and process the waste liquid.

[0026] Preferably, a cover plate is provided on the extension portion, and the driving assembly includes a driving member, gear 1, and gear 2. The driving member is provided on the bracket, gear 1 is provided at the output end of the driving member, gear 2 is engaged with gear 1, and gear 2 is coaxially fixedly connected to the cover plate. The driving member drives the annular cylinder to rotate through gear 1 and gear 2.

[0027] The driving member drives the cover plate to rotate through gear 1 and gear 2, and the rotation of the cover plate drives the annular cylinder to rotate synchronously.

[0028] Preferably, the drive assembly also includes two groups of transmission parts 1 and 2 with the same structure, and the transmission part 1 and the transmission part 2 are respectively arranged at the middle plates at both ends of the annular cylinder. The transmission part 1 includes: a transmission plate, a ratchet, and a pawl. The ratchet is coaxially fixedly connected to the middle plate, the pawl is rotatably connected to the transmission plate, and the pawl cooperates with the ratchet. The cooperation direction of the pawl and the ratchet in the transmission part 1 and the transmission part 2 is the same, the transmission plate in the transmission part 1 is fixedly connected to the cover plate, and the transmission plate in the transmission part 2 is fixedly connected to the exhaust pipe.

[0029] When the annular cylinder rotates counterclockwise, the pawl in transmission member 1 rotates around the ratchet wheel, and the pawl in transmission member 2 engages with the ratchet wheel, securing the intermediate plate and preventing it from rotating with the annular cylinder. When the annular cylinder rotates clockwise, the pawl in transmission member 1 engages with the ratchet wheel, and the pawl in transmission member 2 rotates relative to the ratchet wheel, causing the intermediate plate to rotate synchronously with the annular cylinder.

[0030] Preferably, a discharge port 1 is provided at the bottom of the magnetic ring, and a discharge port 2 is provided on the side of the annular cylinder. When the discharge port 2 rotates to the bottom of the annular cylinder, it corresponds to the discharge port 1. A solenoid valve is provided in the discharge port 2 to control the closing of the discharge port 2.

[0031] When the waste liquid needs to be discharged, the annular cylinder drives the discharge port 2 to rotate to the bottom of the annular cylinder. At this time, the discharge port 2 corresponds to the discharge port 1. The waste liquid can be discharged through the discharge port 2 and the discharge port 1 by opening the discharge port 2.

At the same time, the rotation of the annular cylinder causes little disturbance to the waste liquid during the process, avoiding affecting the flocculation effect, so as to carry out subsequent treatment and improve the treatment effect of the waste liquid.

[0047] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0048] like Figures 1 to 11 As shown, the laboratory waste liquid treatment device of the present invention includes a bracket 1 installed in a treatment tank 01, a cylinder 2 for treating waste liquid is provided on the bracket 1, a cleaning component 3, a driving component 4, an impurity removal component 7, and a control component 8 are provided in the cylinder 2, the driving component 4 is connected to the cleaning component 3 for controlling the cleaning component 3, the cleaning component 3 is used to collect metal impurities in the waste liquid, the control component 8 is connected to the cleaning component 3 for controlling the metal impurities collected in the cleaning component 3 to be discharged into the impurity removal component 7, and finally discharged through the impurity removal component 7.

[0049] Reference Figure 2 、 Figure 3 、 Figure 8 The cylinder 2 includes: an annular cylinder 21 and an intermediate plate 22. The annular cylinder 21 is rotatably assembled on the bracket 1. Two intermediate plates 22 are provided, and the two intermediate plates 22 are respectively arranged at both ends of the annular cylinder 21. The annular cylinder 21 is placed horizontally. The intermediate plate 22 and the annular cylinder 21 are rotatably matched. The intermediate plate 22 and the annular cylinder 21 are enclosed to form a cavity 221 for placing waste liquid. The cavity 221 is cylindrical.

[0050] Reference Figure 2 、 Figure 3 、 Figure 4 、 Figure 5The cleaning assembly 3 includes: a magnetic ring 31, a collection frame 32, and a scraper 33. The magnetic ring 31 is configured in an arc shape and is sleeved on the outside of the annular cylinder 21. An electromagnetic coil is installed in the magnetic ring 31. When the electromagnetic coil is energized, the magnetic ring 31 becomes magnetic. The collection frame 32 is disposed in the annular cylinder 21 and is connected to the intermediate plate 22. The collection frame 32 is located above the axis of the annular cylinder 21. The scraper 33 is disposed on the collection frame 32. The lower end of the scraper 33 is connected to the collection frame 32, and the upper end is inclined in a clockwise direction and abuts against the inner wall of the annular cylinder 21. The upper end of the scraper 33 is located above the collection frame 32. An opening 311 is provided at the top of the magnetic ring 31, and the opening 311 corresponds to the collection frame 32.

[0051] The inner side of the magnetic ring 31 is close to the annular cylinder 21, and the metal impurity particles deposited at the bottom of the annular cylinder 21 are adsorbed, so that the metal impurities stick to the inner wall of the annular cylinder 21. The driving component 4 is connected to the annular cylinder 21 to drive the annular cylinder 21 to rotate around the middle plate 22. When the annular cylinder 21 rotates counterclockwise, it drives the metal impurities to rotate synchronously, drives the metal impurities to separate from the waste liquid, and rotates to the top of the inner wall of the annular cylinder 21. When the metal impurities move to the top of the collection frame 32, the metal impurities move to the opening 311 of the magnetic ring 31, and the metal impurities leave the adsorption range of the magnetic ring 31 and fall into the collection frame 32. As the annular cylinder 21 continues to rotate, the scraper 33 scrapes off the remaining metal impurities on the annular cylinder 21, guides and collects them into the collection frame 32.

[0052] Reference Figure 5 、 Figure 6 、 Figure 7 The scraper 33 is rotatably mounted on the collection frame 32. A torsion spring is provided at the connection between the scraper 33 and the collection frame 32. The torsion spring drives the scraper 33 to rotate, so that the upper end of the scraper 33 maintains abutment with the inner wall of the annular cylinder 21. A connecting rod 5 is provided on the side of the collection frame 32 near the intermediate plate 22. The connecting rod 5 is coaxial with the rotating axis of the scraper 33. The collection frame 32 is connected to the intermediate plate 22 via the connecting rod 5. The connecting rod 5 is rotatably mounted on the intermediate plate 22. The end of the connecting rod 5 facing away from the collection frame 32 extends to the outside of the cavity 221. A stop rod 51 is provided on the side of the connecting rod 5, and the stop rod 51 is located outside the cavity 221. An extension portion 211 is provided on the annular cylinder 21. The extension portion 211 is sleeved on the outside of the baffle rod 51 and is coaxial with the axis of the annular cylinder 21. A plurality of levers 212 are provided on the extension portion 211 and are arranged circumferentially around the extension portion 211. The levers 212 and the baffle rod 51 are both arranged in a direction toward the axis of the annular cylinder 21. A drainage hole 322 is provided on the side of the collection frame 32 away from the scraper 33.

[0053] The driving assembly 4 drives the annular cylinder 21 to rotate around the middle plate 22, and the extension part 211 also rotates around the middle plate 22. The rotation of the extension part 211 drives the lever 212 to pass through the baffle 51 in turn. When the lever 212 moves to the baffle 51, the lever 212 abuts against the baffle 51 to drive the collecting frame 32 to rotate upward on the side away from the connecting rod 5. After the lever 212 is separated from the baffle 51, the side of the collecting frame 32 away from the connecting rod 5 rotates to the initial position again under the action of its own gravity. The reciprocating swing of the collecting frame 32 is realized by multiple levers 212 to throw out the moisture contained in the metal impurities, and in the initial state, the end of the collecting frame 32 away from the connecting rod 5 is tilted downward so that the moisture can flow out through the drainage hole 322.

[0054] Reference Figure 5 、 Figure 6 The collection frame 32 is provided with a mounting portion 323, which is located on a side of the collection frame 32 away from the scraper 33. A drainage hole 322 is provided on the mounting portion 323. A placement cavity 324 is defined within the mounting portion 323 for receiving liquid medicine for treating wastewater. The mounting portion 323 is provided with an outlet 325 communicating with the placement cavity 324. When the collection frame 32 swings, the mounting portion 323 swings, causing the liquid medicine in the placement cavity 324 to be ejected. Simultaneously, the annular cylinder 21 rotates, evenly distributing the liquid medicine throughout the wastewater, thereby treating the wastewater.

[0055] Reference Figure 6 、 Figure 7 A clearance groove 222 is also defined on the side of the middle plate 22 near the baffle rod 51. The side of the baffle rod 51 extends into the clearance groove 222. Multiple protrusions are located within the clearance groove 222, corresponding to the end of the baffle rod 51 facing away from the connecting rod 5. As the baffle rod 51 rotates with the collection frame 32, it moves past the multiple protrusions, causing the collection frame 32 to vibrate, thereby draining moisture from the collection frame 32. Furthermore, after the lever 212 separates from the baffle rod 51, the baffle rod 51 abuts against the inner wall of the clearance groove 222, providing support for the collection frame 32.

[0056] Reference Figure 4 、 Figure 5 A push plate 6 is slidably assembled in the collection frame 32, and a spring 61 connecting the push plate 6 and the collection frame 32 is provided between the push plate 6 and the collection frame 32. The spring 61 is set as a spring, which is used to drive the push plate 6 to move toward the direction of the rotating shaft of the scraper 33. The upper end of the push plate 6 slides and abuts against the inner side of the scraper 33.

[0057] When the blocking rod 51 drives the collecting frame 32 to rotate, the collecting frame 32 rotates upward at one end away from the scraper 33, so that the distance between the scraper 33 and the collecting frame 32 is reduced, driving different positions on the scraper 33 to abut against the push plate 6, so as to drive the push plate 6 to move in the collecting frame 32. When the push plate 6 moves, it scrapes off the impurities adhering to the scraper 33, thereby improving the collection effect of the impurities.

[0058] Reference Figure 3 、 Figure 8 The impurity discharge assembly 7 includes: an impurity discharge pipe 71, a guide frame 72, a spiral piece 73, and a power piece 74. The impurity discharge pipe 71 is coaxially arranged with the annular cylinder 21. The guide frame 72 is arranged on the impurity discharge pipe 71 and is connected to the inside of the impurity discharge pipe 71. The guide frame 72 is arranged in the vertical direction, and the upper end of the guide frame 72 is arranged close to the collecting frame 32. The spiral piece 73 is rotatably assembled in the impurity discharge pipe 71, and the power piece 74 is arranged as a motor. The end of the impurity discharge pipe 71 extends to the outside of the cavity 221. An outlet 2 711 is provided on the impurity discharge pipe 71. The outlet 2 711 is located outside the cavity 221. The power piece 74 is arranged at one end of the impurity discharge pipe 71 outside the annular cylinder 21, and the output end of the power piece 74 is connected to the spiral piece 73 to drive the spiral piece 73 to rotate.

[0059] Reference Figure 4 、 Figure 5 、 Figure 6 An outlet 1 321 is provided below the collecting frame 32 , and a control component 8 is provided on the collecting frame 32 . The control component 8 is provided at the outlet 1 321 for controlling the closing of the outlet 1 321 .

[0060] The control component 8 opens the outlet 1 321 , and the impurities in the collecting frame 32 enter the impurity discharge pipe 71 through the guide frame 72 . The power member 74 drives the spiral piece 73 to rotate, transporting the impurities and discharging the impurities through the outlet 2 711 .

[0061] Reference Figure 4 、 Figure 5 The control assembly 8 includes a slide 81, a push rod 82, and a second elastic member 83. The slide 81 is slidably mounted on the bottom of the collection frame 32. The slide 81 slides at the first outlet 321 to control the opening and closing of the first outlet 321. The push rod 82 is connected to the slide 81 and is located within the collection frame 32. The push rod 82 is arranged along the sliding direction of the push plate 6. The second elastic member 83 is configured as a spring and is connected to the slide 81 and the collection frame 32. The second elastic member 83 drives the slide 81 to slide outside the first outlet 321 to close the first outlet 321.

[0062] Reference Figure 7The extension portion 211 is provided with a control rod 213, which is arranged along the axis of the annular cylinder 21. The length of the control rod 213 is greater than the length of the shift rod 212. Therefore, the angle at which the control rod 213 drives the blocking rod 51 to rotate is greater than the angle at which the shift rod 212 drives the blocking rod 51 to rotate.

[0063] When the lever 212 engages with the stopper 51, the push plate 6 slides within the collection frame 32 but does not contact the push rod 82. When the control lever 213 engages with the stopper 51, the collection frame 32 rotates at a greater angle, and the push plate 6 moves a greater distance. At this time, the push plate 6 moves to engage with the push rod 82 and drives the push rod 82 to move. The movement of the push rod 82 drives the slide plate 81 to open the outlet 1 321 to discharge the metal impurities in the collection frame 32.

[0064] Reference Figure 3 、 Figure 4 A discharge port 1 312 is defined at the bottom of the magnetic ring 31, and a discharge port 215 is defined on the side of the annular cylinder 21. When the discharge port 215 is rotated to the position directly below the annular cylinder 21, it aligns with the discharge port 1 312. A solenoid valve is located within the discharge port 215 to control its closure. To discharge the waste liquid from the cavity 221, the annular cylinder 21 is rotated so that the discharge port 215 aligns with the discharge port 1 312. The discharge port 215 is then opened to discharge the waste liquid.

[0065] Reference Figure 8 A cover plate 214 is provided on the extension portion 211 . Two cover plates 214 are provided and are located at both ends of the annular cylinder 21 . The cover plates 214 are arranged parallel to the middle plate 22 and spaced apart. The cover plates 214 are fixedly connected to the annular cylinder 21 .

[0066] Reference Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 The drive assembly 4 includes a drive member 41, a gear 1 42, a gear 2 43, a transmission member 1 44, and a transmission member 2 45. The drive member 41 is mounted on the bracket 1 and is configured as a motor. Gear 1 42 is located at the output end of the drive member 41. Gear 2 43 is coaxially connected to the cover plate 214, and gear 1 42 meshes with gear 2 43. The drive member 41 drives the cover plate 214 to rotate via gear 1 42 and gear 2 43, which in turn drives the annular cylinder 21 to rotate.

[0067] Reference Figure 9 、 Figure 10 、 Figure 11Transmission member 1 44 and transmission member 2 45 have the same structure and are provided in a one-to-one correspondence with the two intermediate plates 22. Each transmission member 1 44 and transmission member 2 45 includes a transmission plate 441, a ratchet 442, and a pawl 443. The ratchet 442 is coaxially fixedly connected to the intermediate plate 22. The pawl 443 is rotatably assembled on the transmission plate 441 and engages with the ratchet 442. The ratchet 442 and pawl 443 in transmission member 1 44 and transmission member 2 45 engage in the same direction. The transmission plate 441 in transmission member 1 44 is fixedly connected to the cover plate 214, while the transmission plate 441 in transmission member 2 45 is fixedly connected to the impurity discharge pipe 71.

[0068] By providing the transmission member 1 44 and the transmission member 2 45 , when the annular cylinder 21 rotates counterclockwise, the middle plate 22 is fixed, and when the annular cylinder 21 rotates clockwise, the middle plate 22 rotates synchronously.

[0069] When the gear 2 43 drives the annular cylinder 21 to rotate counterclockwise, the transmission plate 441 in the transmission member 1 44 rotates synchronously with the cover plate 214. At this time, the transmission plate 441 drives the pawl 443 to rotate around the ratchet 442. The transmission plate 441 in the transmission member 2 45 always remains fixed. The pawl 443 in the transmission member 2 45 engages with the ratchet 442 to restrict the intermediate plate 22, thereby reducing the phenomenon that the intermediate plate 22 rotates counterclockwise with the annular cylinder 21, so as to clean metal impurities.

[0070] When the gear 2 43 drives the annular cylinder 21 to rotate clockwise, the transmission plate 441 in the transmission member 1 44 drives the pawl 443 to engage with the ratchet 442, driving the intermediate plate 22 to rotate along with the annular cylinder 21. At the same time, the pawl 443 in the transmission member 2 45 separates from the ratchet 442, causing the intermediate plate 22 to rotate synchronously with the annular cylinder 21 in the clockwise direction.

[0071] When metal impurities need to be cleaned, the annular drum 21 rotates counterclockwise, while the intermediate plate 22 remains stationary. After the metal impurities have been processed and discharged through the impurity discharge pipe 71, the annular drum 21 rotates clockwise, and the intermediate plate 22 rotates synchronously with the annular drum 21. The rotation direction of the intermediate plate 22 is aligned with the inclination direction of the scraper 33. When the scraper 33 moves below the rotation axis of the annular drum 21, it scrapes up the non-metallic precipitated impurities at the bottom of the annular drum 21. The annular drum 21 continues to rotate, and when the scraper 33 again rotates above the collection frame 32, the scraped precipitated impurities are transferred to the collection frame 32 for subsequent discharge through the impurity discharge pipe 71.

[0072] When flocculants are added to the wastewater to flocculate the heavy metals in the wastewater, the floccules will sink to form a sludge layer. At this time, the annular cylinder 21 can be rotated clockwise to drive the scraper 33 to rotate to the bottom of the annular cylinder 21, scraping up the settled floccules and collecting them in the collection frame 32.

[0073] In order to facilitate the scraper 33 to collect flocculants or precipitated non-metallic impurities, a number of small through holes can be opened on the scraper 33 so that when the scraper 33 moves through the bottom of the annular cylinder 21, the flocculants or precipitated impurities can enter between the scraper 33 and the collection frame 32.

[0074] Since the non-metallic precipitated impurities are not attracted by the magnetic ring 31 , they will always be at the bottom of the annular cylinder 21 when the annular cylinder 21 rotates. After the scraper 33 rotates to the bottom of the annular cylinder 21 , these impurities can be scraped up and collected.

[0075] Reference Figure 3 A feeding pipe 9 is coaxially mounted on the intermediate plate 22. The intermediate plate 22 is rotatably mounted on the feeding pipe 9. One end of the feeding pipe 9 extends into the annular cylinder 21. A feeding port 91 is provided below the feeding pipe 9. The feeding port 91 is located within the annular cylinder 21. Waste liquid is fed into the annular cylinder 21 through the feeding pipe 9. Furthermore, because the feeding pipe 9 and the intermediate plate 22 are coaxially mounted, the level of the waste liquid fed into the annular cylinder 21 is lower than the axis of the annular cylinder 21, thereby reducing backflow of the waste liquid.

[0076] The implementation principle of the present invention is as follows: the driving member 41 drives the annular cylinder 21 to rotate counterclockwise. At this time, the pawl 443 in the transmission member 1 44 is not engaged with the ratchet 442, and the pawl 443 rotates around the ratchet 442. The pawl 443 in the transmission member 2 45 is engaged with the ratchet 442 to fix the middle plate 22, so that the middle plate 22 remains fixed when the annular cylinder 21 rotates counterclockwise. During the process, the scraper 33 and the collecting frame 32 are always above the axis of the annular cylinder 21.

[0077] The magnetic ring 31 adsorbs the metal impurity particles at the bottom of the annular cylinder 21, so that the metal impurity particles stick to the inner wall of the annular cylinder 21 and rotate with the annular cylinder 21. When the metal impurity particles rotate to above the collection frame 32, they also move to the opening 311 of the magnetic ring 31, leaving the adsorption range of the magnetic ring 31, and the metal impurities fall into the collection frame 32. The annular cylinder 21 continues to rotate, and the scraper 33 scrapes off the remaining impurities on the inner wall of the annular cylinder 21 and guides them into the collection frame 32.

[0078] During this process, the multiple levers 212 sequentially pass through the stop bar 51, driving the collection frame 32 to swing, thereby draining water contained in the impurities from the drainage holes 322. When the control lever 213 moves to the stop bar 51, the collection frame 32 rotates closer to the scraper 33, driving the push plate 6 to move until it abuts the push rod 82, which in turn drives the slide plate 81 to move, opening the outlet 1 321. After the outlet 1 321 is opened, the impurities in the collection frame 32 fall through the guide frame 72 and are discharged into the impurity discharge pipe 71.

[0079] Under the action of the magnetic ring 31, the precipitated metal impurities are separated and collected from the waste liquid. During the process, the annular cylinder 21 rotates, which causes less disturbance to the flocs and reduces the phenomenon of the flocs being broken up, so as to carry out subsequent separation operations and improve the treatment effect of sewage.

[0080] Although the embodiments of the present invention have been shown and described above, it will be understood that the above embodiments are illustrative and are not to be construed as limitations on the present invention. A person skilled in the art may change, modify, replace and modify the above embodiments within the scope of the present invention.
