Description

[0001] This invention is a divisional application of the following patent application: Application No. 202310174320.8; Application Date 2023.02.28; Invention Title: A preparation device for a composite flocculant. Technical Field

[0002] This invention relates to the field of flocculant technology, specifically to a device for preparing a composite flocculant. Background Technology

[0003] Flocculants can be broadly classified into two categories based on their chemical composition: inorganic flocculants and organic flocculants. Inorganic flocculants include inorganic coagulants and inorganic polymeric flocculants, while organic flocculants include synthetic organic polymeric flocculants, natural organic polymeric flocculants, and microbial flocculants.

[0004] Existing flocculants are usually prepared by directly mixing them with water or other solutions without staged mixing or grading filtration to filter out large volumes of flocculants. This results in uneven mixing and affects the flocculant's effectiveness.

[0005] Chinese Patent CN217221255U discloses a device for preparing an inorganic composite flocculant for dyeing and printing wastewater. The device includes a preparation cylinder, a first feed hopper, a second feed hopper, a filtration mechanism, a first stirring mechanism, a second stirring mechanism, and a third stirring mechanism. The first feed hopper is fixedly connected to the left side of the upper end of the preparation cylinder, and the second feed hopper is fixedly connected to the right side of the upper end of the preparation cylinder. The filtration mechanism is located inside the preparation cylinder, the first stirring mechanism is located above the inside of the preparation cylinder, and the second stirring mechanism is located below the first stirring mechanism. This device for preparing an inorganic composite flocculant for dyeing and printing wastewater can perform graded filtration of the flocculant by setting two filter screens with decreasing mesh diameters.

[0006] The aforementioned prior art addresses the technical problem that existing flocculants, when stirred, do not undergo segmented stirring with water or other solutions, nor do they perform graded filtration to remove large volumes of flocculant, leading to uneven stirring and affecting the flocculant's effectiveness. The applicant has developed a new technical solution to solve the aforementioned technical problems during actual production. Summary of the Invention

[0007] The purpose of this invention is to provide a device for preparing a composite flocculant, which has the advantages of segmented stirring of the flocculant with water or other solutions and graded filtration of the flocculant.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0009] This invention provides a preparation device for a composite flocculant, comprising a mixing tank, two U-shaped frames, and a discharge pipe disposed at the bottom of the mixing tank. The discharge pipe is equipped with a shut-off valve. Two opposing feed pipes are disposed at the top of the mixing tank. Both U-shaped frames are located inside the mixing tank and are vertically opposite each other, with both frames inclined. The mixing tank is equipped with a vibrating element for simultaneously driving the two U-shaped frames to vertically shake up and down. A first filter screen is disposed in the upper U-shaped frame along its inclined direction, and a second filter screen is disposed in the lower U-shaped frame along its inclined direction. The mixing tank is equipped with a stirring element for stirring the upper and lower sides of the second filter screen and the area above the first filter screen. The mesh diameter of the first filter screen is larger than that of the second filter screen.

[0010] By adopting the above technical solution, the flocculant and other solutions are separately fed into the mixing tank through two feed pipes. Then, the shaking component simultaneously drives the two U-shaped frames to shake vertically up and down, and the agitator performs primary agitation on the flocculant above the first filter screen. After primary agitation, the large volume of flocculant is filtered out by the first filter screen, and the filtered flocculant is located above the second filter screen. Then, the agitator performs secondary agitation on the flocculant above the second filter screen. After secondary agitation, the large volume of flocculant is filtered out by the second filter screen, and the filtered flocculant is located below the second filter screen. Finally, the agitator agitates the flocculant below the second filter screen, thus completing the segmented agitation. Because the mesh diameter of the first filter screen is larger than that of the second filter screen, the flocculant can be filtered in stages through the first and second filters. When the shaking component simultaneously drives the two U-shaped frames to shake vertically up and down, the filtration efficiency of the first and second filters can be improved. It is simple and convenient to use.

[0017] Preferably, the stirring component includes a fourth rotating shaft rotatably connected to the top of the stirring tank and a fifth rotating shaft rotatably connected to the bottom of the stirring tank. The bottom end of the fourth rotating shaft passes through a first filter screen and has a first hemispherical block located below the first filter screen.

Detailed Implementation

[0032] 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 scope of protection of the present invention.

[0033] An apparatus for preparing a composite flocculant, such as Figure 1 and Figure 2The system includes a mixing tank 1, two U-shaped frames 2, and a discharge pipe 3 located at the bottom of the mixing tank 1. The discharge pipe 3 is equipped with a shut-off valve 4. The top of the mixing tank 1 is equipped with two opposing feed pipes 5. The two U-shaped frames 2 are located inside the mixing tank 1 and are vertically opposite each other. The two U-shaped frames 2 are inclined. The mixing tank 1 is equipped with a vibrating component for simultaneously driving the two U-shaped frames 2 to shake vertically up and down. The upper U-shaped frame 2 is equipped with a first filter screen 6 along the inclined direction of the U-shaped frame 2, and the lower U-shaped frame 2 is equipped with a second filter screen 7 along the inclined direction of the U-shaped frame 2. The mixing tank 1 is equipped with a stirring component for stirring the upper and lower sides of the second filter screen 7 and the top of the first filter screen 6 inside the mixing tank 1. The mesh diameter of the first filter screen 6 is larger than the mesh diameter of the second filter screen 7.

[0034] like Figure 1 and Figure 2 The flocculant and other solutions are fed into the mixing tank 1 through two feed pipes 5. A vibrating element simultaneously drives two U-shaped frames 2 to shake vertically up and down. The agitator then performs primary agitation on the flocculant above the first filter screen 6. After primary agitation, a large volume of flocculant is filtered out by the first filter screen 6, leaving the filtered flocculant above the second filter screen 7. The agitator then performs secondary agitation on the flocculant above the second filter screen 7. After secondary agitation, a large volume of flocculant is filtered out by the second filter screen 7, leaving the filtered flocculant below the second filter screen 7. This completes the segmented agitation. Because the mesh diameter of the first filter screen 6 is larger than that of the second filter screen 7, the flocculant can be filtered in stages through the first and second filters. When the vibrating element simultaneously drives the two U-shaped frames 2 to shake vertically up and down, the filtration efficiency of the first and second filters is improved. The process is simple and convenient to use.

[0035] like Figure 1 and Figure 2 and Figure 4The first filter screen 6 is flush with the upper surface of the upper loop frame 2, and the second filter screen 7 is flush with the upper surface of the lower loop frame 2. The shaking component includes a first rod 8 and a second rod 9. The first rod 8 is vertically fixed between the two loop frames 2, and the second rod 9 is vertically fixed to the top of the upper loop frame 2. The top of the second rod 9 extends vertically through the mixing tank 1 to the outside of the mixing tank 1 and is rotatably connected to a roller 10. A support plate 12 is vertically provided at the top of the mixing tank 1, and a cam 13 is rotatably connected to one side of the support plate 12. The cam 13 is located below the roller 10 and contacts the roller 10. A first motor 14 for driving the cam 13 to rotate is provided on the support plate 12. Two vertically opposite recesses are opened on one side of the outer wall of the mixing tank 1. The outer wall of the mixing tank 1, near the opening of the groove 15, is bolted with a sealing plate 16 for sealing the opening of the groove 15. The two grooves 15 correspond one-to-one with the two loop frames 2. The purpose of this setting is that when it is necessary to drive the two loop frames 2 to shake vertically up and down at the same time, it is only necessary to turn on the first motor 14. At this time, the rotating shaft of the first motor 14 drives the cam 13 to rotate. Then, through the cooperation of the cam 13 and the roller 10, the second rod 9 can be pushed to drive the two loop frames 2 and the first rod 8 to shake vertically up and down. After stirring and filtering, the bolts are unscrewed, the two sealing parts are removed, and the groove 15 is opened. The large volume of flocculant filtered on the first filter screen 6 and the second filter screen 7 can be taken out from the groove 15. It is simple and convenient to use.

[0036] like Figure 1 and Figure 4 The second rod 9 is located on opposite sides of the mixing tank 1, and a third rod 17 is horizontally provided. A tension spring 18 is provided between the bottom end of the third rod 17 and the top end of the mixing tank 1. The purpose of this setting is that when the rotating shaft of the first motor 14 drives the cam 13 to rotate, and the cam 13 and the roller 10 cooperate to push the second rod 9 to drive the two loop frames 2 and the first rod 8 to shake vertically up and down, the tension spring 18 can keep the roller 10 in contact with the cam 13. This reduces the possibility of the roller 10 separating from the cam 13 due to inertia when the rotating cam 13 drives the second rod 9 to drive the two loop frames 2 and the first rod 8 to move vertically upward through the roller 10. This makes it simple and convenient to use.

[0037] like Figure 2The mixing component includes a rotating groove 19 disposed at the top of the mixing tank 1 and communicating with the mixing tank 1. A first rotating shaft 20 is rotatably connected inside the rotating groove 19. The bottom end of the first rotating shaft 20 extends outside the rotating groove 19 and passes through the first filter screen 6 and the second filter screen 7. The first rotating shaft 20 is provided with a plurality of first stirring rods 21, a plurality of second stirring rods 22, and a plurality of third stirring rods 23. Each first stirring rod 21 is located above the first filter screen 6, each second stirring rod 22 is located between the first filter screen 6 and the second filter screen 7, and each third stirring rod 23 is located below the second filter screen 7. The top end of the first rotating shaft 20 is coaxially fixedly connected to a first gear 24 located outside the mixing tank 1. The mixing tank 1 is provided with a rotating component for driving the first rotating shaft 20 to rotate at a different speed through the first gear 24.

[0038] like Figure 2 When it is necessary to stir the upper and lower sides of the second filter screen 7 and the top of the first filter screen 6 in the mixing tank 1, it is only necessary to drive the first gear 24 to rotate by the rotating component. At this time, the first gear 24 drives the first rotating shaft 20 to rotate. Through the first stirring rods 21 located above the first filter screen 6, the second stirring rods 22 located above the second filter screen 7, and the third stirring rods 23 located below the second filter screen 7 on the first rotating shaft 20, the upper and lower sides of the second filter screen 7 and the top of the first filter screen 6 can be stirred. It is simple and convenient to use.

[0039] like Figure 2 and Figure 3 The rotating component includes a bracket 25 mounted on the top of the mixing tank 1, and a turntable 26 rotatably connected to the bracket 25. The bottom end of the turntable 26 is coaxially provided with a circular groove 27, and a disc 28 is coaxially provided inside the circular groove 27. A first gear 24 is located between the disc 28 and one side wall of the circular groove 27. The outer wall of the disc 28 is provided with a plurality of first protruding teeth 29 that mesh with the first gear 24, and each first protruding tooth 29 is distributed on a part of the outer wall of the disc 28. The groove wall of the circular groove 27 is provided with a plurality of second protruding teeth 30, and each second protruding tooth 30 is distributed on a part of the groove wall of the circular groove 27. A second motor 31 for driving the turntable 26 to rotate is provided on the bracket 25.

[0040] like Figure 2 and Figure 3When the second motor 31 is turned on, its rotating shaft drives the turntable 26 to rotate clockwise. The turntable 26 then drives the disc 28 to rotate along its axis. The first tooth 29 on the disc 28 drives the first gear 24 to rotate counter-clockwise. As the turntable 26 rotates, the first gear 24 disengages from the first tooth 29 and engages with the second teeth 30. With the rotation of the turntable 26, the second teeth 30 then drive the first gear 24 to rotate counter-clockwise. The first gear 24 rotates clockwise at a speed greater than its counterclockwise rotation speed. As the turntable 26 rotates, after the first gear 24 separates from the second tooth 30, it will re-engage with the first tooth 29. The first gear 24 drives the first shaft 20 to rotate at a different speed, which in turn drives the first stirring rod 21, the second stirring rod 22, and the third stirring rod 23 to rotate at a different speed along the axis of rotation of the first shaft 20. This improves the stirring effect and makes the machine simple and convenient to use.

[0041] like Figure 5 and Figure 6Alternatively, the mixing component includes a second rotating shaft 32 rotatably connected to the top of the mixing tank 1 and a third rotating shaft 33 rotatably connected to the bottom of the mixing tank 1. The bottom end of the second rotating shaft 32 passes through the first filter screen 6 and is provided with a first swing arm 34 located below the first filter screen 6. The top end of the third rotating shaft 33 passes through the second filter screen 7 and is provided with a second swing arm 35 located above the second filter screen 7. A sliding barrel 36 is horizontally provided on one side of the inner wall of the mixing tank 1, located between the first filter screen 6 and the second filter screen 7, and the sliding barrel 36 is horizontal. A sliding column 37 is slidably connected. A cylinder 38 is provided at one end of the outer wall of the mixing tank 1 near the sliding barrel 36. One end of the piston rod of the cylinder 38 passes through the tank wall of the mixing tank 1 and extends into the sliding barrel 36, where it is fixedly connected to the sliding column 37. The end of the sliding column 37 away from the cylinder 38 extends horizontally to the outside of the sliding barrel 36 and is connected to the first swing arm 34 and the second swing arm 35 through the first transmission assembly. When the piston rod of the cylinder 38 drives the sliding column 37 to move horizontally, the horizontally moving sliding column 37 is connected to the first transmission assembly, the first swing arm 34, and the second swing arm 35 through the first transmission assembly. A first swing arm 34 and a second swing arm 35 drive a second rotating shaft 32 and a third rotating shaft 33 to rotate. The second rotating shaft 32 has several first stirring blades 39 positioned above the first filter screen 6, and the third rotating shaft 33 has several second stirring blades 40 positioned below the second filter screen 7. The first transmission assembly includes two push plates 41 disposed at the end of the slide column 37 away from the cylinder 38. A rotating column 42 is vertically disposed between opposite sides of the push plates 41, and two opposing rotating rings 43 are coaxially rotatably connected to the rotating column 42. The first swing arm... The end of the first swing arm 34 away from the second rotating shaft 32 is rotatably connected to the third swing arm 44, and the end of the third swing arm 44 away from the first swing arm 34 is fixedly connected to the outer wall of one of the rotating rings 43. The end of the second swing arm 35 away from the third rotating shaft 33 is rotatably connected to the fourth swing arm 45, and the end of the fourth swing arm 45 away from the second swing arm 35 is fixedly connected to the outer wall of another rotating ring 43. Several stirring columns 46 located between the first filter screen 6 and the second filter screen 7 are provided on the outer walls of the third rotating shaft 33 and the second rotating shaft 32.

[0042] like Figure 5 and Figure 6When it is necessary to stir the upper and lower sides of the second filter screen 7 and the top of the first filter screen 6 in the mixing tank 1, simply open the cylinder 38. At this time, the piston rod of the cylinder 38 pushes the slide column 37 to drive the push plate 41, the two rotating rings 43, and the rotating column 42 to move horizontally back and forth. Since the third swing arm 44 is rotatably connected to the first swing arm 34, and the end of the third swing arm 44 away from the first swing arm 34 is fixedly connected to the outer wall of one of the rotating rings 43, and the fourth swing arm 45 is rotatably connected to the second swing arm 35, and the end of the fourth swing arm 45 away from the second swing arm 35 is fixedly connected to the outer wall of the other rotating ring 43, when the piston rod of the cylinder 38 pushes the slide column 37 to drive the push plate 41, the two rotating rings 43, and the rotating column 42 to move horizontally back and forth... When moving, the rotation of the second rotating shaft 32 and the third rotating shaft 33 is achieved through the cooperation of the rotating column 42 with one of the rotating rings 43 and the third swing arm 44 and the first swing arm 34, as well as the cooperation of the fourth swing arm 45 with the second swing arm 35. At this time, the second rotating shaft 32 drives the first stirring plate 39 to stir the area above the first filter screen 6, and the third rotating shaft 33 drives the second stirring plate 40 to stir the area below the second filter screen 7. The third rotating shaft 33 and the second rotating shaft 32 drive the stirring column 46 to stir the area between the second filter screen 7 and the first filter screen 6. When the first swing arm 34 and the second swing arm 35 are misaligned, the rotation directions of the second rotating shaft 32 and the third rotating shaft 33 are opposite, making it simple and convenient to use.

[0043] like Figure 7 and Figure 8Alternatively, the mixing components include a fourth rotating shaft 47 rotatably connected to the top of the mixing tank 1 and a fifth rotating shaft 48 rotatably connected to the bottom of the mixing tank 1. The bottom end of the fourth rotating shaft 47 passes through the first filter screen 6 and is provided with a first hemispherical block 49 located below the first filter screen 6. The top end of the fifth rotating shaft 48 passes through the second filter screen 7 and is provided with a second hemispherical block 50 located above the second filter screen 7. The fourth rotating shaft 47 is provided with a plurality of third stirring blades 51 located above the first filter screen 6, and the fifth rotating shaft 48 is provided with a plurality of fourth stirring blades 52 located below the second filter screen 7. A third electric shock is provided on one side of the outer wall of the mixing tank 1. The third motor 53 has a rotating shaft that extends through the wall of the mixing tank 1 and into the mixing tank 1, and is equipped with a drive disk 54. The first hemispherical block 49 and the second hemispherical block 50 are vertically opposite each other and are both located on the side of the drive disk 54 away from the third motor 53. When the rotating shaft of the third motor 53 drives the drive disk 54 to rotate, the drive disk 54 is equipped with a second transmission assembly for driving the first hemispherical block 49 and the second hemispherical block 50 to rotate alternately. On the side of the drive disk 54 near the third motor 53, a plurality of fifth stirring blades 55 are arranged along the circumference of the drive disk 54. The first hemispherical block 49 and the second hemispherical block 50 form a... The hollow sphere 56 and the second transmission assembly include four first hemispherical grooves 57 and four first grooves 58 disposed on the outer wall of the first hemispherical block 49 and communicating with the bottom end of the first hemispherical block 49. The four first hemispherical grooves 57 and 58 are evenly distributed along the circumference of the first hemispherical block 49, and the four first grooves 58 are respectively located between two adjacent first hemispherical grooves 57. The outer wall of the second hemispherical block 50 is provided with four second hemispherical grooves 59 and four second grooves 60, and the four second hemispherical grooves 59 and 60 are all communicating with the top end of the second hemispherical block 50. Both slots 60 are evenly distributed along the circumference of the second hemispherical block 50, and the four second slots 60 are respectively located between two adjacent second hemispherical slots 59. The drive disk 54 is provided with a semi-circular plate 61 on the side away from the third motor 53, and the semi-circular plate 61 is located in one of the first hemispherical slots 57 and contacts the slot wall of the first hemispherical slot 57. An inclined plate 62 is provided on one side of the drive disk 54, and the end of the inclined plate 62 away from the drive disk 54 is inclined towards the hollow ball 56 and is provided with a pusher 63. The end of the pusher 63 away from the inclined plate 62 passes through one of the second slots 60 and is located in the hollow ball 56.

[0044] like Figure 7 and Figure 8When it is necessary to stir the upper and lower sides of the second filter screen 7 and the top of the first filter screen 6 in the mixing tank 1, simply turn on the third motor 53. At this time, the rotating shaft of the third motor 53 drives the drive disk 54 to rotate. The drive disk 54 drives the semi-circular plate 61, the inclined plate 62, the push column 63, and the fifth stirring blade 55 to rotate along the rotation axis of the drive disk 54. At this time, because the end of the push column 63 away from the inclined plate 62 passes through one of the second grooves 60 and is located in the hollow sphere 56, the semi-circular plate 61 is located in one of the first semi-circular grooves 57. The inner part of the plate 61 is in contact with the wall of the first semi-circular groove 57. Therefore, when the drive disk 54 drives the semi-circular plate 61, the inclined plate 62, and the push column 63 to rotate along the rotation axis of the drive disk 54, the push column 63 can drive the second hemispherical block 50 to rotate the fifth rotating shaft 48 through the cooperation of one of the second grooves 60. At this time, the fourth stirring plate 52 on the fifth rotating shaft 48 can stir the area below the second filter screen 7, and the fifth stirring plate 55 on the drive disk 54 can stir the area between the second filter screen 7 and the first filter screen 6.

[0045] As the second hemispherical block 50 rotates, the four second grooves 60 on the second hemispherical block 50 correspond one-to-one with the four first grooves 58 on the first hemispherical block 49. At this time, the four first semicircular grooves 57 correspond one-to-one with the four second semicircular grooves 59. The vertically opposite first semicircular grooves 57 and second semicircular grooves 59 form a circular groove 27. At this time, as the drive disk 54 rotates, the semicircular plate 61 will enter the corresponding second semicircular groove 59 from one of the first semicircular grooves 57. The push column 63 will enter the corresponding first groove 58 from one of the second grooves 60. Through the cooperation of the push column 63 and one of the first grooves 58, the first hemispherical block 49 is pushed to drive the fourth rotating shaft 47 to rotate. At this time, the second hemispherical block 50 stops rotating. At this time, the third stirring plate 51 on the fourth rotating shaft 47 can stir the area above the first filter screen 6.

[0046] As the first hemispherical block 49 rotates, the four first grooves 58 on the first hemispherical block 49 correspond one-to-one with the four second grooves 60 on the second hemispherical block 50. At this time, as the drive disc 54 rotates, the semicircular plate 61 will enter the next first semicircular groove 57 on the first hemispherical block 49, and the pusher 63 will enter the next second groove 60. Through the cooperation of the pusher 63 and one of the second grooves 60, the second hemispherical block 50 is pushed to drive the fifth rotating shaft 48 to rotate. At this time, the first hemispherical block 49 stops rotating. Through the above process, the first hemispherical block 49 and the second hemispherical block 50 can rotate alternately, thereby causing the fourth rotating shaft 47 and the fifth rotating shaft 48 to rotate alternately. The rotation directions of the first hemispherical block 49 and the second hemispherical block 50 are opposite, which is simple and convenient to use.

[0047] like Figure 8The first hemispherical block 49 is provided with several L-shaped first stirring plates 64, and each first stirring plate 64 is located above the first groove 58 and is evenly distributed along the circumference of the first hemispherical block 49. The second hemispherical block 50 is provided with several L-shaped second stirring plates 65, and each second stirring plate 65 is located below the second groove 60 and is evenly distributed along the circumference of the second hemispherical block 50. The purpose of this arrangement is that when the first hemispherical block 49 and the second hemispherical block 50 rotate, the first stirring plates 64 on the first hemispherical block 49 and the second stirring plates 65 on the second hemispherical block 50 can further stir the second filter screen 7 and the first filter screen 6, which is simple and convenient to use.

[0048] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
