Description

Technical Field

[0001] This invention relates to the field of water purification medium preparation technology, specifically to an efficient and synergistic device and method for preparing natural water purification media. Background Technology

[0002] As people's living standards improve, their requirements for the environment also increase. Natural water bodies, such as garden landscape water bodies and residential area landscape water bodies, urban rivers and ponds, natural and artificial lakes, are good places for people to relax and enjoy boating. However, with the increase in human traffic, the pollution caused by human activities and other factors has exceeded the self-purification capacity of natural water bodies. Usually, purification media are added to natural water bodies to purify them.

[0003] Currently, when preparing purification media, tailings slag is typically mixed with riverbed sediment and lightly aerated at 200-600 degrees Celsius to solidify, forming porous reactive media particles for purifying natural water bodies. During the preparation of these purification media, mixing equipment is required to combine the tailings slag and riverbed sediment. However, existing mixing equipment has the following shortcomings: First, it lacks a pulverizing structure, making it impossible to pulverize the tailings slag as it enters the mixing equipment. To ensure uniform mixing of the tailings slag and riverbed sediment, separate pulverizing equipment is usually necessary first. The existing equipment suffers from several problems. First, the tailings slag is crushed and then transferred to a mixing device to be mixed with riverbed sediment, resulting in low mixing efficiency. Second, existing equipment typically uses a single feed inlet, with both tailings slag and riverbed sediment added from the same location. Since tailings slag is dry and hard particles while riverbed sediment is wet and sticky, their physical properties differ significantly. If the wet material passes through the crushing and screening stages, it is highly prone to clogging, affecting the smooth operation of the equipment. Third, the existing equipment has a relatively simple mixing structure, making it difficult to simultaneously achieve efficient and uniform mixing of materials in both horizontal and vertical directions, and clogging easily occurs during discharge. These issues lead to low mixing efficiency of tailings slag and riverbed sediment, increasing manual workload and thus reducing the efficiency of natural water purification media preparation. Summary of the Invention

[0004] The purpose of this invention is to provide an efficient and synergistic device and method for preparing natural water purification media, thereby solving the aforementioned problems in the prior art.

[0007] Furthermore, the discharge pipe is a threaded pipe, the outer diameter of the small spiral component is adapted to the inner diameter of the threaded pipe, and a threaded cap is threadedly connected to the lower part of the discharge pipe.

[0008] Furthermore, the stirring assembly also includes a third guide plate, which is inclinedly disposed in the lower middle part of the device body. The top end of the third guide plate is fixedly installed on the side wall near the collection tank, and the top end of the fourth rotating shaft is rotatably installed on the third guide plate.

[0010] Furthermore, the screening mechanism includes a sieve plate, a second rotating shaft, a rotating component, and a coil spring. The second rotating shaft is rotatably installed in the middle of the side wall of the device body near the second feed inlet. The rotating component is fixedly installed on the second rotating shaft. The sieve plate is fixedly installed on the side of the rotating component away from the second feed inlet. A drive assembly is provided below the end of the sieve plate away from the rotating component. The sieve plate is correspondingly arranged with the collection groove. The coil spring is slidably sleeved in the middle of the second rotating shaft. The two ends of the coil spring are respectively fixedly embedded in the device body and the rotating component.

[0011] Furthermore, the drive assembly includes a third rotating shaft and a second motor. The third rotating shaft is rotatably mounted on the side of the device body away from the second feed inlet. Several cams are evenly fixedly mounted on the third rotating shaft. The top of the cams contacts the bottom of the screen plate. One end of the third rotating shaft is fixedly connected to the output shaft of the second motor. The second motor is electrically connected to the controller.

[0012] Furthermore, the crushing assembly includes a first guide plate, a first rotating shaft, a second guide plate, and a first motor. The first guide plate is symmetrically and fixedly installed on both sides of the top of the equipment body. The second guide plate is inclinedly arranged in the upper middle part of the equipment body, and the top of the second guide plate is fixedly installed on the side wall of the equipment body away from the second feed inlet.

Step 2: The crushing component inside the upper part of the equipment body crushes the tailings slag, and the crushed tailings slag falls onto the screening mechanism. Step 3: The screening mechanism screens the crushed tailings slag. The small tailings slag particles screened out fall into the lower part of the equipment body and mix with the river bottom mud added in Step 1. Step 4: The mixing assembly operates by driving the mixing plate, large spiral component, and small spiral component to rotate via the fourth rotating shaft. The mixing plate mixes the mixture horizontally, while the large and small spiral components mix the mixture vertically, ensuring that the tailings slag and riverbed sediment are evenly mixed. Step 5: Discharge the evenly mixed material from the discharge pipe at the bottom of the equipment body.

Simultaneously, riverbed sediment is directly conveyed to the mixing zone below the screening mechanism through a second feed inlet, achieving simultaneous feeding of dry and wet materials in separate zones and preventing wet materials from clogging the crushing component and screening mechanism. The screening mechanism, in conjunction with a vacuum feeder, can automatically re-crush incompletely crushed tailings slag, improving raw material utilization. The alternating arrangement and coordinated rotation of the stirring plate, large spiral component, and small spiral component in the mixing component achieves simultaneous multi-dimensional mixing of the mixture in both horizontal and vertical directions, and the small spiral component's location within the discharge pipe prevents discharge blockage. These synergistic technical features result in a more uniform mixing of tailings slag and riverbed sediment, significantly reducing manual labor and substantially improving the mixing efficiency of tailings slag and riverbed sediment, thereby efficiently and synergistically enhancing the preparation efficiency of natural water purification media.

[0025] Specifically, the mixing assembly includes a third guide plate 24 and a fourth rotating shaft 25. The third guide plate 24 is inclinedly disposed in the lower middle part of the equipment body 1, and the top end of the third guide plate 24 is fixedly installed on the side of the equipment body 1 away from the second feed inlet 3.

The large spiral components 29 are used to mix the small-particle tailings slag and riverbed sediment in the vertical direction. Small spiral components 30 are fixedly installed on the bottom end of the fourth rotating shaft 25. The small spiral components 30 are used to accelerate the discharge rate of the mixed small-particle tailings slag and riverbed sediment.

[0026] Furthermore, a third motor 26 is fixedly connected to the top of the fourth rotating shaft 25. The third motor 26 drives the fourth rotating shaft 25 to rotate. The large spiral component 29 and the stirring plate 28 are arranged alternately, and the small spiral component 30 is arranged inside the discharge pipe 4. The housing of the third motor 26 is fixedly installed on the top of the third guide plate 24. The output shaft of the third motor 26 is fixedly connected to the top of the fourth rotating shaft 25. The third motor 26 is electrically connected to the controller 6. At this time, the controller 6 can control the opening and closing of the third motor 26. A protective box 27 is provided on the third motor 26, and the bottom end of the protective box 27 is fixedly installed on the top of the third guide plate 24. The protective box 27 is used to protect the third motor 26 and prevent it from being damaged by small particles of tailings.

[0027] Meanwhile, the crushing assembly includes a first guide plate 7, a first rotating shaft 8, and a second guide plate 12. The first guide plate 7 is symmetrically and fixedly installed on both sides of the top of the equipment body 1. The second guide plate 12 is inclinedly arranged in the upper part of the equipment body 1, and the top of the second guide plate 12 is fixedly installed on the side of the equipment body 1 away from the second feed inlet 3. The first rotating shaft 8 is symmetrically and rotatably installed on both sides of the upper part of the equipment body 1. One end of each of the two first rotating shafts 8 is fixedly connected to a first motor 11, which drives the first rotating shaft 8 to rotate. A roller 9 is fixedly installed in the middle of each of the two first rotating shafts 8. Crushing cones 10 are evenly fixedly installed on the side of the device. The crushing cones 10 can crush tailings slag by rotating. The crushing cones 10 of the two drums 9 are arranged alternately. The housings of the two first motors 11 are fixedly installed on the side of the device body 1 near the controller 6. The output shafts of the two first motors 11 are respectively fixedly connected to the end of the first rotating shaft 8 near the controller 6. The two first motors 11 are electrically connected to the controller 6. The controller 6 controls the opening and closing of the first motors 11 and controls the rotation direction of the output shafts of the first motors 11. The rotation directions of the output shafts of the two first motors 11 are opposite.

[0028] In this embodiment 1, the screening mechanism includes a second rotating shaft 18, which is rotatably installed in the middle of the side of the equipment body 1 near the second feed inlet 3. A rotating component 19 is fixedly installed on the second rotating shaft 18, and a screen plate 17 is fixedly installed on the side of the rotating component 19 away from the second feed inlet 3. The screen plate 17 is used to screen the crushed tailings and screen out the incompletely crushed tailings. A drive component is provided below the end of the screen plate 17 away from the rotating component 19. The bottom of the end of the screen plate 17 away from the rotating component 19 is in contact with the input end of the vacuum feeder. A coil spring 20 is slidably sleeved in the middle of the second rotating shaft 18. The coil spring 20 is used to drive the screen plate 17 to rotate in the opposite direction and reset. The two ends of the coil spring 20 are respectively fixedly embedded in the equipment body 1 and the rotating component 19.

[0029] The drive assembly includes a third rotating shaft 21 and a second motor 23. The third rotating shaft 21 is rotatably installed on the side of the equipment body 1 away from the second feed inlet 3. Several cams 22 are evenly fixedly installed on the third rotating shaft 21. The top of each cam 22 contacts the bottom of the screen plate 17. The rotation of the cams 22 can intermittently push the screen plate 17 to rotate upward, while the coil spring 20 can drive the screen plate 17 to rotate downward and reset, so that the screen plate 17 vibrates back and forth within a certain angle range, thereby quickly screening the crushed tailings and improving the screening efficiency of the tailings. The end of the third rotating shaft 21 near the controller 6 is fixedly connected to the output shaft of the second motor 23. The housing of the second motor 23 is fixedly installed on the side of the equipment body 1 near the controller 6, and the second motor 23 is electrically connected to the controller 6. The controller 6 controls the opening and closing of the second motor 23.

[0030] Preferably, the equipment for the efficient synergistic preparation of natural water purification media in Embodiment 1 of the present invention further includes a vacuum feeder 15. The vacuum feeder 15 is fixedly installed on the top of the equipment body 1 on the side away from the second feed inlet 3. The vacuum feeder 15 is electrically connected to the controller 6, and the controller 6 controls the opening and closing of the vacuum feeder 15. The output end of the vacuum feeder 15 is fixedly connected to the top of the equipment body 1 near the vacuum feeder 15 through the discharge pipe 16. The input end of the vacuum feeder 15 is fixedly connected to a collection tank 13 through the feed pipe 14. The collection tank 13 is fixedly installed in the middle of the equipment body 1 on the side away from the second feed inlet 3, and the top of the collection tank 13 near the second feed inlet 3 is in contact with the bottom of the sieve plate 17. When the vacuum feeder 15 is working, the incompletely crushed tailings are transported to the top of the equipment body 1 for re-feeding through the feed pipe 14 and the discharge pipe 16, thereby realizing secondary crushing, so that the tailings can be completely crushed and the crushing effect is better.

[0031] In the use of the high-efficiency synergistic preparation of natural water purification media in Embodiment 1 of the present invention, the operator can start the second motor 23, the third motor 26 and the two first motors 11 through the controller 6, and then transport the tailings and river bottom sediment into the equipment body 1 through the first feed port 2 and the second feed port 3 respectively: the tailings are transported to the upper part of the equipment body 1 through the first feed port 2, and the river bottom sediment is transported to the lower part of the equipment body 1 through the second feed port 3. The controller 6 controls the output shafts of the two first motors 11 to rotate in opposite directions. The operation of the two first motors 11 drives the two first rotating shafts 8 and the two drums 9 to rotate, thereby causing the crushing cones 10 on the two drums 9 to rotate, so that the crushing cones 10 on the two drums 9 rotate in opposite directions, thereby crushing the tailings that enter the equipment body 1 into small particles of tailings. The crushed tailings fall onto the second guide plate 12 and slide down the second guide plate 12 onto the screen plate 17.

[0032] The crushed tailings are screened through the screen plate 17. The second motor 23 drives the third rotating shaft 21 to rotate. The rotation of the third rotating shaft 21 causes the cam 22 to rotate. When the protruding end of the cam 22 gradually contacts the end of the screen plate 17 away from the second feed inlet 3, the cam 22 can push the end of the screen plate 17 away from the second feed inlet 3 to move upward, so that the screen plate 17 rotates counterclockwise with the second rotating shaft 18 and the rotating part 19. At this time, the coil spring 20 is in a compressed state. When the protruding end of the cam 22 gradually disengages from the end of the screen plate 17 away from the second feed inlet 3, the force of the coil spring 20 can drive the screen plate 17, the second rotating shaft 18 and the rotating part 19 to rotate in the opposite direction, so that the screen plate 17 rotates clockwise, so that the screen plate 17 vibrates back and forth within a certain angle range, thereby quickly screening the crushed tailings and improving the screening efficiency of the tailings.

[0033] At this time, the incompletely crushed tailings fall into the collection tank 13 along the screen plate 17. When the vacuum feeder 15 is working, it transports the incompletely crushed tailings to the top of the equipment body 1 through the feed pipe 14 and the discharge pipe 16 for re-feeding, thereby realizing secondary crushing, so that the tailings can be completely crushed and the crushing effect is better.

[0034] The screened small-particle tailings fall onto the third guide plate 24 and enter the lower part of the equipment body 1 along the third guide plate 24. The riverbed sediment enters the lower part of the equipment body 1 through the second feed inlet 3. The third motor 26 drives the fourth rotating shaft 25 to rotate. The rotation of the fourth rotating shaft 25 causes the stirring plate 28, the large spiral component 29, and the small spiral component 30 to rotate. The rotation of the stirring plate 28 can stir the small-particle tailings and riverbed sediment in the horizontal direction. The large spiral component 29 and the small spiral component 30 can stir the small-particle tailings and riverbed sediment in the vertical direction. This achieves stirring of the small-particle tailings and riverbed sediment in both the horizontal and vertical directions, making the small-particle tailings and riverbed sediment more evenly mixed and achieving a better mixing effect.

[0035] After the small-particle tailings and riverbed sediment are evenly mixed, the workers rotate the threaded cover 5 and remove it from the discharge pipe 4. At this time, the mixed small-particle tailings and riverbed sediment are discharged through the discharge pipe 4. The rotation of the small spiral component 30 can accelerate the discharge rate and prevent blockage. This allows the tailings to be crushed when it enters the mixing equipment, and the incompletely crushed tailings can be crushed multiple times. The crushed tailings and riverbed sediment can be stirred horizontally and vertically, resulting in good mixing effect and more uniform mixing of the crushed tailings and riverbed sediment. This greatly reduces the amount of manual labor, improves the mixing efficiency of tailings and riverbed sediment, and thus improves the efficiency of natural water purification media preparation.

[0036] Example 2 The method for efficiently and synergistically preparing natural water purification media according to Embodiment 2 of the present invention, using the aforementioned equipment, includes the following steps: Step 1: The tailings slag is transported to the upper part of the equipment body 1 through the first feed port 2, and the river bottom mud is transported to the lower part of the equipment body 1 through the second feed port 3. Step 2: The crushing component inside the upper part of the equipment body 1 crushes the tailings slag, and the crushed tailings slag falls onto the screening mechanism. Step 3: The screening mechanism screens the crushed tailings slag. The small tailings slag particles screened out fall into the lower part of the equipment body 1 and mix with the river bottom mud added in step 1. Step 4: The mixing assembly operates by driving the mixing plate 28, the large spiral component 29, and the small spiral component 30 to rotate via the fourth rotating shaft 25. The mixing plate 28 mixes the mixture horizontally, while the large spiral component 29 and the small spiral component 30 mix the mixture vertically, so that the tailings slag and riverbed mud are mixed evenly. Step 5: Discharge the evenly mixed material from the discharge pipe 4 at the bottom of the equipment body 1.

[0037] The device and method for efficiently and synergistically preparing natural water purification media of the present invention utilizes a crushing component to crush tailings slag upon its entry into the equipment, eliminating the need for pre-crushing and intermediate transfer. Simultaneously, riverbed sediment is directly conveyed to the mixing zone below the screening mechanism through a second feed inlet, achieving simultaneous feeding of dry and wet materials in separate zones and preventing wet materials from clogging the crushing component and screening mechanism. The screening mechanism, in conjunction with a vacuum feeder, can automatically re-crush incompletely crushed tailings slag, improving raw material utilization. The alternating arrangement and coordinated rotation of the stirring plate, large spiral component, and small spiral component in the mixing component achieves simultaneous multi-dimensional mixing of the mixture in both horizontal and vertical directions, and the small spiral component's location within the discharge pipe prevents discharge blockage. These synergistic technical features result in a more uniform mixing of tailings slag and riverbed sediment, significantly reducing manual labor and substantially improving the mixing efficiency of tailings slag and riverbed sediment, thereby efficiently and synergistically enhancing the preparation efficiency of natural water purification media.
