Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and in particular to a multi-stage wastewater treatment device. Background Technology

[0002] With the rapid development of industries such as chemical engineering, pharmaceuticals, and electroplating, the discharge of industrial wastewater containing heavy metals, organic solvents, and recalcitrant compounds continues to increase. This type of chemical wastewater is characterized by its complex composition, high toxicity, and poor biodegradability, making it difficult to effectively treat using traditional wastewater treatment processes. The demand for chemical wastewater treatment equipment in environmental monitoring stems from the specific technical requirements of the work, the mandatory provisions of standards and regulations, the need to ensure the quality of test data, and the economic considerations of improving testing efficiency. Specialized chemical wastewater treatment equipment has become an indispensable key component of modern environmental monitoring systems. Its technological development level directly affects the accuracy and reliability of environmental monitoring data. Furthermore, specific testing of treated wastewater yields more accurate results. However, existing environmental monitoring chemical wastewater treatment equipment may experience problems such as excessively rapid wastewater discharge or excessive impurities in the treated wastewater, affecting the effectiveness of subsequent environmental monitoring. Summary of the Invention

[0003] To address the aforementioned technical problems, the present invention adopts the following technical solution: a multi-stage wastewater treatment device, comprising an action mechanism for treating chemical wastewater; the action mechanism includes a treatment cylinder, and is equipped with a feeding mechanism for adding wastewater and additives in equal proportions and a recovery mechanism for collecting sediments; The operating mechanism includes a transmission column rotatably mounted on the processing cylinder, a mixing cylinder and a vortex generator fixedly installed inside the processing cylinder, a vortex track provided inside the vortex generator, an inner cylinder fixedly installed on the vortex generator, and a discharge block fixedly installed at the bottom of the inner cylinder.

[0004] Furthermore, the operating mechanism also includes a motor fixedly installed inside the processing cylinder, the motor driving the transmission column to rotate via a transmission belt, a water outlet pipe being provided on the processing cylinder, a mixing blade shaft being rotatably installed on the processing cylinder, and the transmission column driving the mixing blade shaft to rotate via a transmission belt.

[0005] Furthermore, a closed cylinder is rotatably mounted outside the mixing cylinder, and a lever is fixedly mounted on the closed cylinder. The lever is slidably mounted with the processing cylinder. Several holes are provided on the side of the mixing cylinder and several holes are provided on the side of the closed cylinder. In the initial state, the holes of the mixing cylinder and the closed cylinder are staggered.

[0006] After the wastewater and additives begin to enter the mixing drum, the holes in the closed drum are misaligned with the holes in the mixing blade shaft. At this time, the water in the mixing drum flows into the inner drum and the collection chamber. The motor drives the transmission column to rotate via belt drive, and the transmission column drives the mixing blade shaft to rotate via belt drive. The mixing blade shaft stirs and mixes the wastewater and additives, accelerating the mixing reaction speed. The resulting sediment settles to the bottom of the collection chamber. When the water level reaches a certain level, the lever is manually turned to rotate the closed drum, aligning the holes in the closed drum with the holes in the mixing drum. At this time, the wastewater that has been mixed with the additives flows into the space between the vortex generator and the inner drum through the holes in the closed drum and the mixing drum. The wastewater spirals out along the vortex track of the vortex generator and is finally discharged from the outlet pipe. The vortex track inside the vortex generator ensures that the wastewater at the bottom is discharged first during drainage. After the closed drum rotates and opens, wastewater and additives can be continuously introduced into the subsequent inlet pipe and additive pipe. Only when the machine is first started does it need to be filled with water before the lever and the closed drum are opened.

[0007] Furthermore, the feeding mechanism includes a water inlet pipe and an additive pipe fixedly installed on the processing cylinder. A fan blade is rotatably installed inside the water inlet pipe, and a vertical pipe is fixedly installed on the additive pipe, which is connected to an external additive bottle.

[0008] Furthermore, a rotating gear is rotatably mounted on the additive tube, and a driving rotating rod is fixedly mounted on the rotating gear. The fan blade drives the rotating gear to rotate via belt transmission. A driven rotating rod is rotatably mounted on the driving rotating rod, and a pushing rotating rod is rotatably mounted on the driven rotating rod. A pusher column is rotatably mounted on the pushing rotating rod, and the pusher column slides inside the additive tube.

[0009] Furthermore, the pusher column is provided with a groove, which is a through groove.

[0010] Wastewater enters through the inlet pipe, causing the fan blades to rotate. The fan blades drive the rotating gear and the driving rod via a transmission belt. The driving rod drives the driven rod to rotate, which in turn drives the pushing rod to rotate. This causes the driven rod to slide along the inner wall of the additive tube, and the additive in the riser falls into the groove. When the pusher slides towards the additive tube, the groove reaches the top of the vertical section of the additive tube, and the additive enters the mixing cylinder through the additive tube. At this point, the pusher seals the bottom of the riser. When the pusher moves outward and resets, the groove reaches the bottom of the riser again, and the additive in the riser falls into the groove. This process repeats continuously. The sliding speed of the pusher is controlled by the rotation speed of the fan blades, achieving a proportional addition of wastewater and additives.

[0011] Furthermore, the recycling mechanism includes a recycling cylinder fixedly installed below the discharge block. The recycling cylinder is divided into two chambers: a lead screw slide chamber and a collection chamber. A discharge plate is slidably installed on the recycling cylinder.

[0012] Furthermore, a turntable is rotatably installed inside the processing cylinder, a swing rod is eccentrically rotatably installed on the turntable, a lower rotating rod is rotatably installed on the swing rod, the lower rotating rod is fixedly installed with the transmission column, an internal gear ring is fixedly installed below the turntable, a central rotating gear is rotatably installed inside the processing cylinder, a small gear is rotatably installed on the discharge block, and a central gear is rotatably installed on the recovery cylinder. The central gear is provided with multiple through slots. The central rotating gear meshes with the internal gear ring, the central rotating gear meshes with the small gear, and the small gear meshes with the central gear.

[0013] Furthermore, an internal threaded bracket is fixedly installed inside the inner cylinder, and a lifting screw is rotatably installed inside the internal threaded bracket via a thread. The lifting screw is provided with a vertical sliding groove, and the lifting screw is slidably installed with the central gear through the vertical sliding groove. A lower push plate is fixedly installed on the lifting screw, and multiple water-passing sliding columns are slidably installed on the lower push plate. An opening block is fixedly installed on the water-passing sliding column, and the lower surface of the opening block is a conical surface. A water-passing spring is provided between the water-passing sliding column and the lower push plate.

[0014] The rotation of the transmission column drives the lower rotating rod to rotate. The lower rotating rod, through the swing rod, drives the turntable and internal gear ring to rotate reciprocally relative to the processing cylinder. The internal gear ring drives the central rotating gear to rotate, which in turn drives the pinion gear to rotate, thereby driving the central gear to rotate. The rotation of the central gear drives the lifting screw to rotate. Under the action of the internal thread frame, the lifting screw moves up and down relative to the central gear, thus realizing the spiral movement of the lifting screw, which in turn drives the lower push plate to move up and down. The turntable rotates reciprocally, causing the lifting screw and the lower push plate to descend to the lowest point and then rise to the highest point, repeating this cycle. When the lower push plate descends, it pushes the water and sediment in the inner cylinder to be removed. The material is pushed downwards, and the continuous downward pressure of the push plate compacts the sediment into the collection chamber. During the downward movement of the push plate, when it can no longer press down due to water pressure, the water-passing slide column and the opening block will be lifted. The opening block will no longer block the water passage, and the water-passing spring will be compressed, allowing water to be discharged through the water passage to the top of the push plate. However, the sediment cannot pass through the water passage, and eventually the sediment is continuously compacted into the collection chamber. When the push plate rises, it will push the water in the inner cylinder upwards into the mixing cylinder. When it is necessary to deal with the sediment in the collection chamber, simply open the discharge plate to remove the sediment.

[0015] The beneficial effects of the present invention compared with the prior art are: (1) The working mechanism set in the present invention can stir the sewage and additives, and at the beginning of use, the mixing cylinder is closed to allow enough time for the initial mixing of sewage and additives. Through the setting of the vortex generator, the lower layer of sewage flows out in advance, providing enough time for the mixing of the continuously introduced sewage and additives; (2) The feeding mechanism set in the present invention can control the speed of additive feeding according to the flow rate of sewage, so that the amount of additive matches the amount of sewage; (3) The recycling mechanism set in the present invention uses the continuously rising and falling lifting screw and the lower push plate to continuously press the precipitated impurities generated after the reaction into the collection chamber to remove impurities in the sewage and collect the impurities uniformly.

Detailed Implementation

[0030] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0031] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of the present invention, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0032] Example: Figures 1-13 As shown, a multi-stage wastewater treatment device includes an action mechanism for treating chemical wastewater; the action mechanism includes a treatment cylinder 101, and is equipped with a feeding mechanism for adding wastewater and additives in equal proportions and a recovery mechanism for collecting sediment. The operating mechanism includes a transmission column 102 rotatably mounted on the processing cylinder 101. A mixing cylinder 110 and a vortex generator 106 are fixedly installed inside the processing cylinder 101. A vortex track is provided inside the vortex generator 106. An inner cylinder 107 is fixedly installed on the vortex generator 106. A discharge block 109 is fixedly installed at the bottom of the inner cylinder 107.

[0033] like Figures 3-6As shown, the operating mechanism also includes a motor 103 fixedly installed inside the processing cylinder 101. The motor 103 drives the transmission column 102 to rotate via a transmission belt. A water outlet pipe 108 is provided on the processing cylinder 101. A mixing blade shaft 111 is rotatably installed on the processing cylinder 101. The transmission column 102 drives the mixing blade shaft 111 to rotate via a transmission belt.

[0034] like Figures 3-6 As shown, a closed cylinder 104 is rotatably mounted on the outside of the mixing cylinder 110. A lever 105 is fixedly mounted on the closed cylinder 104. The lever 105 is slidably mounted on the processing cylinder 101. Several holes are provided on the side of the mixing cylinder 110 and several holes are provided on the side of the closed cylinder 104. In the initial state, the holes of the mixing cylinder 110 and the closed cylinder 104 are staggered.

[0035] After wastewater and additives begin to enter the mixing cylinder 110, the holes in the closed cylinder 104 are misaligned with the holes in the mixing blade shaft 111. At this time, the water in the mixing cylinder 110 flows into the inner cylinder 107 and the collection chamber 310. The motor 103 drives the transmission column 102 to rotate via belt drive, and the transmission column 102 drives the mixing blade shaft 111 to rotate via belt drive. The mixing blade shaft 111 stirs and mixes the wastewater and additives, accelerating the mixing reaction speed. The resulting sediment settles to the bottom of the collection chamber 310. When the water level reaches a certain level, the lever 105 is manually turned to rotate the closed cylinder 104, causing the closed cylinder to rotate. The holes in cylinder 104 are aligned with the holes in mixing cylinder 110. At this time, the wastewater that has been mixed with the additive flows into the space between vortex generator 106 and inner cylinder 107 through the holes in closed cylinder 104 and mixing cylinder 110. The wastewater spirals out along the vortex track of vortex generator 106 and is finally discharged from outlet pipe 108. The vortex track in vortex generator 106 makes the wastewater below discharged first when draining. After closed cylinder 104 is rotated and opened, wastewater and additives can be continuously introduced into subsequent inlet pipe 201 and additive pipe 202. Only when the machine is first turned on does it need to be filled with water before opening lever 105 and closed cylinder 104.

[0036] like Figure 7 , Figure 8 As shown, the feeding mechanism includes a water inlet pipe 201 and an additive pipe 202 fixedly installed on the processing cylinder 101. A fan blade 204 is rotatably installed inside the water inlet pipe 201, and a riser pipe 203 is fixedly installed on the additive pipe 202. The riser pipe 203 is connected to an external additive bottle.

[0037] like Figure 7 , Figure 8As shown, a rotating gear 205 is rotatably mounted on the additive tube 202, and a driving rod 206 is fixedly mounted on the rotating gear 205. The fan blade 204 drives the rotating gear 205 to rotate via belt drive. A driven rod 207 is rotatably mounted on the driving rod 206, and a pushing rod 210 is rotatably mounted on the driven rod 207. A pusher column 208 is rotatably mounted on the pushing rod 210, and the pusher column 208 slides inside the additive tube 202.

[0038] like Figure 7 , Figure 8 As shown, the pusher column 208 is provided with a groove 209, which is a through groove.

[0039] Wastewater enters through the inlet pipe 201. As the wastewater enters, it drives the fan blade 204 to rotate. The fan blade 204 drives the rotating gear 205 and the driving rod 206 to rotate via the transmission belt. The driving rod 206 drives the driven rod 207 to rotate, which in turn drives the pushing rod 210 to rotate. This causes the driven rod 207 to slide along the inner wall of the additive pipe 202. The additive in the riser 203 falls into the groove 209. When the pusher column 208 slides towards the additive pipe 202, the groove 209 reaches the top of the vertical section of the additive pipe 202. The additive enters the mixing cylinder 110 through the additive pipe 202. At this time, the pusher column 208 closes the bottom of the riser 203. When the pusher column 208 moves outward to reset, the groove 209 reaches the bottom of the riser 203 again, and the additive in the riser 203 falls into the groove 209. This process repeats continuously. The sliding speed of the pusher column 208 is controlled by the rotation speed of the fan blade 204, achieving the equal addition of wastewater and additives.

[0040] like Figures 9-13 As shown, the recycling mechanism includes a recycling cylinder 304 fixedly installed below the discharge block 109. The recycling cylinder 304 is divided into two chambers: a screw slide chamber 309 and a collection chamber 310. A discharge plate 305 is slidably installed on the recycling cylinder 304.

[0041] like Figures 9-13 As shown, a turntable 301 is rotatably mounted inside the processing cylinder 101. A swing rod 303 is eccentrically mounted on the turntable 301. A lower rotating rod 302 is rotatably mounted on the swing rod 303. The lower rotating rod 302 is fixedly mounted to the transmission column 102. An internal gear ring 306 is fixedly mounted below the turntable 301. A central rotating gear 307 is rotatably mounted inside the processing cylinder 101. A pinion 308 is rotatably mounted on the discharge block 109. A central gear 311 is rotatably mounted on the recovery cylinder 304. The central gear 311 is provided with multiple through slots 312. The central rotating gear 307 meshes with the internal gear ring 306, the central rotating gear 307 meshes with the pinion 308, and the pinion 308 meshes with the central gear 311.

[0042] like Figures 9-13As shown, an internal threaded bracket 314 is fixedly installed inside the inner cylinder 107. A lifting screw 313 is rotatably installed inside the internal threaded bracket 314 via a thread. A vertical sliding groove 315 is provided on the lifting screw 313. The lifting screw 313 is slidably installed with the central gear 311 through the vertical sliding groove 315. A lower push plate 316 is fixedly installed on the lifting screw 313. Multiple water-passing sliding columns 317 are slidably installed on the lower push plate 316. An opening block 319 is fixedly installed on the water-passing sliding column 317. The lower surface of the opening block 319 is a conical surface. A water-passing spring 318 is provided between the water-passing sliding column 317 and the lower push plate 316.

[0043] The rotation of the transmission column 102 drives the lower rotating rod 302 to rotate. The lower rotating rod 302 drives the turntable 301 and the internal gear ring 306 to reciprocate relative to the processing cylinder 101 via the swing rod 303. The internal gear ring 306 drives the central rotating gear 307 to rotate, which in turn drives the pinion gear 308 to rotate, thereby driving the central gear 311 to rotate. The rotation of the central gear 311 drives the lifting screw 313 to rotate. Under the action of the internal thread frame 314, the lifting screw 313 rises and falls relative to the central gear 311, thus realizing the spiral rise and fall of the lifting screw 313, which in turn drives the lower push plate 316 to rise and fall. The turntable 301 reciprocates, causing the lifting screw 313 and the lower push plate 316 to descend to the lowest point and then rise to the highest point, repeating this process. When the lower push plate 316 descends, it pushes the inner cylinder 101... The water and sediment in the inner cylinder 107 are pushed downwards. The continuous downward pressure of the push plate 316 compacts the sediment in the collection chamber 310. During the downward movement of the push plate 316, when it can no longer press down due to water pressure, the water-passing slide 317 and the opening block 319 will be lifted. The opening block 319 will no longer block the water passage 320, and the water-passing spring 318 will be compressed, allowing water to be discharged through the water passage 320 to the top of the push plate 316. However, the sediment cannot pass through the water passage 320. Finally, the sediment is continuously compacted in the collection chamber 310. When the push plate 316 rises, it will push the water in the inner cylinder 107 upwards into the mixing cylinder 110. When it is necessary to deal with the sediment in the collection chamber 310, the discharge plate 305 can be opened to remove the sediment.

[0044] The working principle of the multi-stage sewage treatment equipment disclosed in this invention is as follows: Sewage is introduced through the inlet pipe 201. As the sewage enters, it drives the fan blade 204 to rotate. The fan blade 204 drives the rotating gear 205 and the active rotating rod 206 to rotate via a transmission belt. The active rotating rod 206 drives the driven rotating rod 207 to rotate, which in turn drives the pushing rod 210 to rotate. This causes the driven rotating rod 207 to slide along the inner wall of the additive pipe 202. The additive in the riser 203 falls into the groove 209. When the pusher column 208 moves towards... When the additive tube 202 slides, the groove 209 reaches the top of the vertical section of the additive tube 202, and the additive enters the mixing cylinder 110 through the additive tube 202. At this time, the pusher column 208 closes the bottom of the riser 203. When the pusher column 208 moves outward to reset, the groove 209 reaches the bottom of the riser 203 again, and the additive in the riser 203 falls into the groove 209. This process is repeated. The sliding speed of the pusher column 208 is controlled by the rotation speed of the fan blade 204 to achieve the addition of wastewater and additive in equal proportion. After wastewater and additives begin to enter the mixing cylinder 110, the holes in the closed cylinder 104 are misaligned with the holes in the mixing blade shaft 111. At this time, the water in the mixing cylinder 110 flows into the inner cylinder 107 and the collection chamber 310. The motor 103 drives the transmission column 102 to rotate via belt drive, and the transmission column 102 drives the mixing blade shaft 111 to rotate via belt drive. The mixing blade shaft 111 stirs and mixes the wastewater and additives, accelerating the mixing reaction speed. The resulting sediment settles to the bottom of the collection chamber 310. When the water level reaches a certain level, the lever 105 is manually turned to rotate the closed cylinder 104, causing the closed cylinder to rotate. The holes in cylinder 104 are aligned with the holes in mixing cylinder 110. At this time, the wastewater that has been mixed with the additive flows into the space between vortex generator 106 and inner cylinder 107 through the holes in closed cylinder 104 and mixing cylinder 110. The wastewater spirals out along the vortex track of vortex generator 106 and is finally discharged from outlet pipe 108. The vortex track in vortex generator 106 makes the wastewater below discharged first when draining. After closed cylinder 104 is rotated and opened, wastewater and additives can be continuously introduced into subsequent inlet pipe 201 and additive pipe 202. Only when the machine is first turned on does it need to be filled with water before opening lever 105 and closed cylinder 104.The rotation of the transmission column 102 drives the lower rotating rod 302 to rotate. The lower rotating rod 302 drives the turntable 301 and the internal gear ring 306 to reciprocate relative to the processing cylinder 101 via the swing rod 303. The internal gear ring 306 drives the central rotating gear 307 to rotate, which in turn drives the pinion gear 308 to rotate, thereby driving the central gear 311 to rotate. The rotation of the central gear 311 drives the lifting screw 313 to rotate. Under the action of the internal thread frame 314, the lifting screw 313 rises and falls relative to the central gear 311, thus realizing the spiral rise and fall of the lifting screw 313, which in turn drives the lower push plate 316 to rise and fall. The turntable 301 reciprocates, causing the lifting screw 313 and the lower push plate 316 to descend to the lowest point and then rise to the highest point, repeating this process. When the lower push plate 316 descends, it pushes the inner cylinder 101... The water and sediment in the inner cylinder 107 are pushed downwards. The continuous downward pressure of the push plate 316 compacts the sediment in the collection chamber 310. During the downward movement of the push plate 316, when it can no longer press down due to water pressure, the water-passing slide 317 and the opening block 319 will be lifted. The opening block 319 will no longer block the water passage 320, and the water-passing spring 318 will be compressed, allowing water to be discharged through the water passage 320 to the top of the push plate 316. However, the sediment cannot pass through the water passage 320. Finally, the sediment is continuously compacted in the collection chamber 310. When the push plate 316 rises, it will push the water in the inner cylinder 107 upwards into the mixing cylinder 110. When it is necessary to deal with the sediment in the collection chamber 310, the discharge plate 305 can be opened to remove the sediment.
