Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, and in particular to a rapid sedimentation device for machine-made sand wastewater treatment. Background Art

[0002] Mechanical sand making refers to sand processed by sand making machines and other ancillary equipment. The finished product is more regular and can be processed into sand of different rules and sizes according to different process requirements, which can better meet daily needs. With the continuous increasing demand for infrastructure construction, the output of machine-made sand has increased year by year, but the contradiction between the large-scale generation of machine-made sand wastewater and environmental protection and water conservancy and flood control is also becoming increasingly prominent.

[0003] There are many impurities in the wastewater from mechanical sand making. For the treatment of wastewater from mechanical sand making, flocculation sedimentation is generally carried out. Flocculation refers to the aggregation and enlargement of suspended particles in water or liquid, or the formation of flocs, thereby accelerating the aggregation of particles and achieving the purpose of solid-liquid separation. The flocculation step can effectively remove suspended impurities in the wastewater.

[0004] However, the existing machine-made sand sewage on the market has problems in the sedimentation work. The traditional method is to mix the flocculant and sewage by rotation mixing for precipitation. However, stirring is also required during the mixing process. The water in the sedimentation tank will rotate during stirring. Although it can be mixed, the sludge and floccules at the bottom of the sedimentation tank will be stirred up during the mixing process. This requires re-sedimentation, which will prolong the sedimentation time and is not conducive to efficient and rapid sedimentation. At the same time, the stirred sludge and floccules are easy to enter the water purification pipe and be discharged.

[0005] Therefore, it is necessary to provide a rapid sedimentation equipment for machine-made sand sewage treatment to solve the above technical problems. Summary of the invention

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] A rapid sedimentation equipment for machine-made sand sewage treatment First embodiment: See also Figures 1 to 12 , comprising a sedimentation box 1, a driving mechanism 5 and a flocculation mechanism 7; The driving mechanism 5 includes a turntable 57, a top plate 2 is fixedly provided on the top of the sedimentation box 1, a protection box 3 is installed on the upper surface of the top plate 2 by bolts, a base 51 is fixedly provided on the upper surface of the top plate 2 and inside the protection box 3, a driving motor 52 is installed on the top of the base 51 by bolts, a first gear 53 is connected to the keyway of the output shaft of the driving motor 52, a second gear 54 is meshedly connected to one side of the first gear 53, a key rod 55 is splined at the axis of the second gear 54, a ratchet 56 is splined to the outer wall of the key rod 55 and located below the base 51, ratchet teeth 58 are installed inside the turntable 57 and on both sides of the ratchet 56 by torsion springs, a rotating ring 59 is concentrically and integrally provided at the bottom of the turntable 57, a limiting ring 510 is rotatably connected to the bottom of the rotating ring 59, limiting rods 511 are fixedly provided on both sides of the limiting ring 510, and limiting plates 512 are fixedly provided at the bottom ends of the two limiting rods 511; Preferably, the drive motor 52 can preferably be a three-phase asynchronous motor, which can realize forward and reverse rotation.

[0022] See also Figure 4 and Figure 5 : Starting the driving motor 52 can control the first gear 53 to mesh with the second gear 54 to rotate forward or reverse. If the second gear 54 rotates counterclockwise, the second gear 54 will drive the internal key rod 55 to synchronously control the ratchet 56 to rotate counterclockwise; The ratchet wheel 56 rotating counterclockwise can engage with the ratchet teeth 58 on both sides of the force control to drive the entire turntable 57 to rotate counterclockwise. When the turntable 57 rotates counterclockwise, it will synchronously drive the rotating ring 59 to make the stirring frame 513 rotate counterclockwise. See also Figure 8 When the stirring frame 513 rotates counterclockwise, it will control the rotating frame 71 to rotate counterclockwise at the center position of the limiting plate 15, and can synchronously control the four outer contact wheels 72 to rotate counterclockwise as well.

[0023] A rotating tube 16 is rotatably mounted at the center of the limiting plate 512, a first toothed disc 17 is fixedly mounted on the top of the rotating tube 16, a baffle 18 is fixedly mounted on the outer wall of the key rod 55 and located below the ratchet 56, a second toothed disc 20 is meshedly connected above the first toothed disc 17, and a return spring 19 is sleeved on the outer wall of the key rod 55 and located between the baffle 18 and the second toothed disc 20; See also Figure 7 , Figure 8 and Fig. 9When the turntable 57, the rotating ring 59 and the stirring frame 513 rotate counterclockwise, the key rod 55 is affected by the ratchet 56 and rotates counterclockwise synchronously. The key rod 55 can drive the second toothed disc 20 at the bottom to rotate counterclockwise on the first toothed disc 17. Since the second toothed disc 20 rotates counterclockwise, the oblique tooth surfaces at the meshing position of the first toothed disc 17 and the second toothed disc 20 will avoid each other. The second toothed disc 20 can rotate and avoid on the first toothed disc 17 by repeatedly moving up and down through the reset spring 19. Therefore, the counterclockwise rotating second toothed disc 20 will not affect the first toothed disc 17. Therefore, in the flocculation working state, the pH adjustment will not rotate.

[0024] The outer wall of the rotating ring 59 is fixed with a stirring frame 513, and the flocculation mechanism 7 includes a rotating frame 71 fixed at the middle position of the bottom of the stirring frame 513, and the rotating frame 71 is rotatably connected with a contact wheel 72, and the number of the contact wheels 72 is four; A limit plate 15 is fixedly provided on the inner wall of the sedimentation box 1, and a fixing frame 14 is fixedly provided inside the sedimentation box 1 and below the limit plate 15. An annular tube 73 is installed inside the fixing frame 14, and two mounting blocks 74 are installed on the outer wall of the annular tube 73 and in the horizontal direction. Two hoses 75 are integratedly provided on the outer wall of the annular tube 73 above the two mounting blocks 74, and nozzles 76 are integrated on the top ends of the two hoses 75. Reset rotating frames 77 are installed on the outer walls of the two mounting blocks 74 through rotation of torsion springs.

[0025] See also Fig.11 : Each abutment wheel 72 rotated counterclockwise to the position of the reset rotating frame 77 will move and resist the bottom of the reset rotating frame 77; See also Fig.12 (a): In the initial state, the reset rotating frame 77 is tilted to the left, and at this time, the reset rotating frame 77 will restrict the nozzle 76 and the hose 75 from tilting to the left as well, and the resistance wheel 72 rotating counterclockwise to the left will resist the force-bearing reset rotating frame 77; See also Fig.12 (b) in the figure: When the reset rotating frame 77 is pushed by the friction wheel 72, the reset rotating frame 77 will switch from the left tilting clockwise to the right tilting state, forming a fan-shaped linkage flipping. During the flipping process, the nozzle 76 will also flip. As the friction wheel 72 continues to rotate away, when the reset rotating frame 77 finally flips to the extreme position, the bottom of the reset rotating frame 77 will be separated from the top of the friction wheel 72. After separation, the reset rotating frame 77 loses the force and automatically resets to Fig.12 In the state (a), a fan-shaped flip is formed again, and the friction wheel 72 that rotates behind will again resist the reset rotating frame 77 to flip, and the rotation in sequence can control the reciprocating fan-shaped flipping movement of the reset rotating frame 77.

[0026] The key rod 55 is rotationally connected to the base 51 , the two ratchet teeth 58 are meshed with the ratchet wheel 56 , the outer wall of the rotating ring 59 is rotationally connected to the top plate 2 via a bearing, and the key rod 55 passes through the interior of the rotating ring 59 and does not contact the rotating ring 59 .

[0027] The axis of the second toothed disc 20 is vertically restricted from sliding about the bottom of the key rod 55 , and the rotating frame 71 is rotatably connected to the limiting plate 15 .

[0028] The outer wall of the nozzle 76 is embedded with each other above the reset rotating frame 77, and the outer wall of the ring tube 73 is integrally provided with a flocculant main pipe 24, which passes through the interior of the top plate 2 and extends to the top of the protection box 3.

[0029] See also Figure 1 and Fig.10 : By adding flocculant into the flocculant main pipe 24, the flocculant can be pumped into the ring pipe 73 through an external pump, and then in turn through the hose 75 and finally sprayed from the nozzle 76 to the water in the sedimentation box 1 for mixing and flocculation.

[0030] This embodiment: Compared with the traditional rotary stirring and mixing design, this case improves the traditional stirring rod into a small stirring frame 513 design. Secondly, in the flocculation and mixing state, the stirring frame 513 is in a counterclockwise rotation state, which will synchronously drive the rotating frame 71 to control the continuous rotation of the resistance wheel 72 to resist the corresponding reset rotating frame 77 to realize the corresponding nozzle 76 to perform a fixed range of fan-shaped reciprocating rotation motion. In this way, during the process of spraying the flocculant, the fan-shaped reciprocating spray can also be performed in the water body for mixing, flocculation and sedimentation. Therefore, such a design can minimize the rotational potential energy in the water body, change the traditional large-scale rotation mixing, and realize multi-frequency small-range flipping spraying, which not only ensures that the flocculant can be well mixed and flocculated with the water body, but also avoids the sediment at the bottom from being stirred up, so that rapid sedimentation can be achieved, further improving the sedimentation speed.

[0031] Second embodiment: See also Figures 5 to 9 , Fig.13 and Fig.14 , further comprising an acid-base regulating mechanism 4, the acid-base regulating mechanism 4 comprising a water pump 41 installed above the protection box 3, a three-way pipe 42 installed at the water inlet end of the water pump 41, an output pipe 43 installed at the water outlet end of the water pump 41, a first rotating joint 44 installed at the bottom end of the output pipe 43, and an injection pipe 45 installed at the bottom end of the first rotating joint 44; A through hole 23 is provided inside the key rod 55, the bottom end of the injection tube 45 is fixedly connected to the top end of the key rod 55, a middle tube 22 is fixedly provided at the bottom end of the key rod 55 and located inside the first gear disc 17 and the second gear disc 20, a second rotary joint 21 is installed at the bottom end of the middle tube 22, acid-base regulating tubes 514 are integrated on both sides of the rotating tube 16, and a stirring plate 515 is fixedly provided on the outer wall of the rotating tube 16 and located below the acid-base regulating tube 514.

[0032] See also Figure 5 and Figure 7 : In the process of the first embodiment, the first embodiment is in a flocculation state, in which the ratchet 56 rotates counterclockwise. In this embodiment, the ratchet 56 needs to be controlled to rotate clockwise. The clockwise rotating ratchet 56 will cause the ratchet teeth 58 to avoid the ratchet 56, so the clockwise rotating ratchet 56 will not affect the rotation of the control dial 57; See 8 and Fig. 9 : The clockwise rotating ratchet 56 will drive the key rod 55 to rotate clockwise, and the key rod 55 will control the second toothed disc 20 to rotate clockwise. Since the second toothed disc 20 rotates clockwise on the first toothed disc 17, a helical tooth meshing is formed, and the first toothed disc 17 will also rotate clockwise. The first toothed disc 17 will drive the rotating tube 16 to drive the acid-base regulating tube 514 and the stirring plate 515 to rotate at the center position of the limiting plate 512. During the rotation process, if the pH value of the water in the sedimentation box 1 is unbalanced, if it is too acidic, it is necessary to add lime water through the three-way pipe 42, through the water pump 41, through the output pipe 43, through the first rotating joint 44, and then through the injection pipe 45 into the through hole 23, and then through the middle pipe 22, through the second rotating joint 21, and finally into the rotating tube 16, and sprayed from the acid-base regulating tubes 514 on both sides into the water body to achieve pH adjustment. Similarly, if the alkalinity of the water body is too high, citric acid solution needs to be added to the water body.

[0033] The bottom end of the second rotary joint 21 and the top end of the rotary tube 16 are sealed and installed, and the rotary tube 16, the second rotary joint 21, the middle tube 22, the key rod 55 and the injection tube 45 are connected from bottom to top.

[0034] It can be understood that: since the key rod 55 and the output pipe 43 are connected through the first rotating joint 44, the key rod 55 rotates clockwise or counterclockwise to ensure that the liquid passes through without interfering with the water pump 41; Secondly, the middle tube 22 and the rotating tube 16 are installed with a second rotating joint 21, so that no matter whether the key rod 55 rotates clockwise or counterclockwise, the liquid can pass smoothly and the interference caused by the rotating tube 16 can be avoided. Fig.14 It can be seen that the rotating tube 16 can be controlled to rotate only when the key rod 55 rotates counterclockwise.

[0035] Please refer again Figure 6 : Since the limiting ring 510 and the rotating ring 59 are rotatably connected, and secondly, the bottom of the entire limiting ring 510 limits the rotation direction of the rotating tube 16 and the first gear disk 17 through the limiting plate 512, no matter how the rotating ring 59 rotates, the rotating tube 16 can be limited to a fixed position.

[0036] This embodiment: Compared with the traditional design, this case can adopt a driving mode of clockwise and counterclockwise rotation to realize flocculation or pH adjustment to work in conjunction with each other, so that the device has the function of pH adjustment. The pH of the water body can be judged before flocculation, and lime water or citric acid can be freely injected according to needs to freely control the pH balance of the water body. At the same time, the addition and stirring of pH are completed in one driving mode, and the rotary injection method and rotary stirring are adopted to ensure the uniformity and stability of water mixing. At the same time, based on the first embodiment, the key rod 55 can start the pH adjustment work when it rotates clockwise, and start the flocculation work when it rotates counterclockwise. The two workpieces can be designed as an integrated design without interfering with each other.

[0037] Third embodiment: Please combine Figure 1 , Figures 15 to 18 , further comprising a discharge mechanism 8, a support plate 6 is fixedly provided on the side wall of the sedimentation box 1, a water inlet frame 11 is fixedly provided on the top of the support plate 6, an interception plate 12 is rotatably connected inside the water inlet frame 11, an overflow plate 9 is installed inside the sedimentation box 1, a clean water outlet 10 is provided on the outer wall of the sedimentation box 1 and outside the overflow plate 9, and a sediment suction pipe 13 is integrally provided on the lower side wall of the sedimentation box 1; The discharge mechanism 8 includes a discharge motor 81 installed on the outer wall of the sedimentation box 1, the output shaft keyway of the discharge motor 81 is connected to a driving pulley 82, the inner bottom of the sedimentation box 1 is rotatably connected to a connecting roller 84 and a pulley roller 83, the outer walls of the pulley roller 83 and the connecting roller 84 are provided with a conveyor belt 85, and the outer walls of the pulley roller 83 and the driving pulley 82 are provided with a belt 86.

[0038] The interception plate 12 is provided with equidistantly arranged oblique grooves therein.

[0039] See also Figure 1 The water to be treated needs to overflow from the water inlet frame 11 into the sedimentation tank 1, and an overflow passage method needs to be adopted because the sludge and gravel in the water body need to be preliminarily treated.

[0040] See also Fig.15 and Fig.16When water flows through the water inlet frame 11, the overflowing water will pass through the obliquely installed interception plate 12. When passing through the interception plate 12, the large gravel in the water will first sink in the largest tooth groove due to gravity. As it continues to flow, the medium gravel and sludge will sink in the middle chute, and finally the lightest sludge will sink in the rightmost chute.

[0041] See also Fig.17 : After the process flow of the first embodiment and the second embodiment, the residual sludge and the successfully flocculated solid medium will all be deposited on the conveyor belt 85 due to gravity. Starting the discharge motor 81 can drive the driving pulley 82 to rotate the transmission belt 86 to control the conveyor belt 85 to move to the left, and the deposited solid medium is concentratedly transported to the sediment suction pipe 13, which can be pumped out by the sludge pump.

[0042] This embodiment: Compared with the traditional direct sedimentation design, this case is designed with an inclined intercepting plate 12, and three sections of inclined troughs with different depths are opened in the intercepting plate 12. During the overflow of water, gravel and sludge of different sizes will automatically settle in the corresponding inclined troughs due to different gravity. Such a design can initially perform physical sedimentation treatment on large gravel and sludge in the water body, which can ensure that the sediment in the water body before flocculation is smaller, which is conducive to rapid sedimentation. Secondly, the sediment after flocculation can be processed in a centralized manner to ensure that the sedimentation box 1 can perform continuous sedimentation work and can process more water to be precipitated in one day.

[0043] Please refer to Figures 1 to 18 The working principle of the rapid sedimentation equipment for machine-made sand sewage treatment provided by the present invention is as follows: Step S1: preliminary treatment of sewage to be precipitated; When the water flows through the water inlet frame 11, the overflowing water will pass through the obliquely installed interception plate 12. When passing through the interception plate 12, the large gravel in the water will first sink in the largest tooth groove due to gravity. As it continues to flow, the medium gravel and sludge will sink in the middle chute, and finally the lightest sludge will sink in the rightmost chute. Step S2: Adjustment of water pH; The control ratchet 56 rotates clockwise, and the clockwise rotating ratchet 56 causes the ratchet teeth 58 to avoid the ratchet 56. Therefore, the clockwise rotating ratchet 56 will not affect the rotation of the control dial 57. The clockwise rotating ratchet 56 will drive the key rod 55 to rotate clockwise. The key rod 55 will control the second toothed disc 20 to rotate clockwise. Since the second toothed disc 20 rotates clockwise on the first toothed disc 17 to form a helical tooth meshing, the first toothed disc 17 will also rotate clockwise. The first toothed disc 17 drives the transmission tube 16 to drive the acid-base regulating tube 514 and the stirring plate 515. The limiting plate 512 rotates at the center position. During the rotation process, if the pH value of the water in the sedimentation box 1 is unbalanced, if it is too acidic, lime water needs to be added through the three-way pipe 42, through the water pump 41, through the output pipe 43, through the first rotating joint 44, and then through the injection pipe 45 into the through hole 23, and then through the middle pipe 22, through the second rotating joint 21, and finally into the rotating pipe 16, and then sprayed out from the acid-base regulating pipes 514 on both sides into the water body to achieve pH adjustment. Similarly, if the alkalinity of the water body is too high, citric acid solution needs to be added to the water body; Step S3: water flocculation and sedimentation; Starting the driving motor 52 can control the first gear 53 to mesh with the second gear 54 to rotate forward or reverse. If the second gear 54 rotates counterclockwise, the second gear 54 will drive the internal key rod 55 to synchronously control the ratchet 56 to rotate counterclockwise. The ratchet wheel 56 rotating counterclockwise can engage with the ratchet teeth 58 on both sides of the force control to drive the entire turntable 57 to rotate counterclockwise. When the turntable 57 rotates counterclockwise, it will synchronously drive the rotating ring 59 to make the stirring frame 513 rotate counterclockwise. When the stirring frame 513 rotates counterclockwise, it controls the rotating frame 71 to rotate counterclockwise at the center of the limiting plate 15, and can synchronously control the four outer contact wheels 72 to rotate counterclockwise as well; When the reset rotating frame 77 is pushed by the resistance wheel 72, the reset rotating frame 77 will switch from tilting to the left side and rotating clockwise to tilting to the right side, forming a fan-shaped linkage flipping. During the flipping process, the nozzle 76 will also flip. As the resistance wheel 72 continues to rotate away, when the reset rotating frame 77 finally flips to the extreme position, the bottom of the reset rotating frame 77 will be separated from the top of the resistance wheel 72, and finally flocculation precipitation will be achieved by spraying flocculant through the nozzle 76.
