A sedimentation device for concrete cleaning slurry

Abstract

This invention relates to the field of wastewater treatment, and more particularly to a sedimentation device for concrete washing slurry, comprising a sedimentation tank, a sedimentation vessel above the sedimentation tank, a drive motor above the sedimentation vessel, a winding wheel fixedly mounted on the output shaft of the drive motor, a connecting belt wound around the outer wall of the winding wheel, a mounting frame fixedly mounted at one end of the connecting belt, a reciprocating cylinder fixedly mounted on the inner wall of the mounting frame, and multiple feeding structures fixedly mounted on the outer wall of the sedimentation vessel. Feeding is completed in the middle of the water body, allowing for more direct contact with suspended solids, promoting mixing and reaction with flocculants, and improving the effectiveness. Simultaneously, the reverse feeding of flocculants in the rotating water body generates a certain shear force, which helps break down large particles or agglomerates in the water, making them easier to contact with the flocculant. This shear force may also promote the interaction between flocculant molecules and suspended particles, thereby accelerating the flocculation process.

Description

Technical Field

[0001] This invention relates to the field of wastewater treatment, and more particularly to a device for settling slurry from concrete cleaning. Background Technology

[0002] Concrete cleaning slurry is wastewater generated during the cleaning of concrete mixer trucks, pumps, and other equipment. It contains a large amount of suspended solids such as cement particles, sand, and additives. Direct discharge of this slurry not only wastes water resources but also pollutes the environment, such as soil and water bodies. Therefore, to prevent environmental pollution and reduce water waste, sedimentation devices are generally used to treat this wastewater, thereby enabling its reuse.

[0003] Existing sedimentation devices typically involve directly placing wastewater into the sedimentation tank and then adding flocculants for sedimentation. However, since sedimentation tanks are generally quite large, the mixing rate between the flocculants and the water is slow after adding the flocculants, which reduces the sedimentation rate and may even affect the sedimentation effect. Furthermore, existing devices directly pump out the water after sedimentation, which makes it impossible to guarantee the treatment effect of the slurry. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the background art by proposing a sedimentation device for concrete cleaning slurry.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0011] In the above-mentioned sedimentation equipment for concrete cleaning slurry, an overflow plate is attached to the outer wall of the sedimentation tank, a water guide box is fixedly installed on the outer wall of the overflow plate, an overflow trough is opened on the inner wall of the sedimentation tank, a sealing baffle is slidably connected to the inner wall of the overflow trough, a screw is rotatably connected to the inner wall of the sedimentation tank, the outer wall of the screw is threadedly connected to the inner wall of the sealing baffle, and an adjustment knob is fixedly installed at one end of the screw.

[0012] In the above-mentioned sedimentation equipment for concrete cleaning slurry, a bottom plate is fixedly connected to the bottom of the sedimentation tank, and a support plate A and a support plate B are fixedly installed on the top of the bottom plate. The support plate A and the support plate B are respectively fixedly connected to the overflow plate and the water guide box.

[0013] In the above-mentioned concrete cleaning slurry sedimentation equipment, an outer frame is fixedly installed on the top of the base plate, an mounting base is fixedly installed on the top of the outer frame, the drive motor is fixedly installed on the inner side of the mounting base, positioning frames are symmetrically fixedly installed on the top of the outer frame, and the winding wheel is rotatably installed between the inner walls of the two positioning frames.

[0014] In the above-mentioned concrete cleaning slurry sedimentation equipment, a connecting frame is fixedly installed on the outer wall of the sedimentation tank, and the output shaft of the reciprocating cylinder is fixedly connected to the top of the connecting frame.

[0015] In the above-mentioned concrete cleaning slurry sedimentation equipment, a horizontal plate is fixedly connected to the bottom of the mounting frame, the reciprocating cylinder is fixedly connected to the top of the horizontal plate, sliders are fixedly installed at both ends of the horizontal plate, and sliding grooves are symmetrically opened on the inner wall of the outer frame, with the two sliders respectively slidingly connected inside the two sliding grooves.

[0016] In the above-mentioned concrete cleaning slurry sedimentation equipment, the bottom of the horizontal plate is symmetrically fixedly connected with limit blocks, the top of the connecting frame is fixedly installed with limit rings, and the inner wall of the limit rings is slidably connected with the outer wall of the limit blocks.

[0017] In the above-mentioned concrete cleaning slurry sedimentation equipment, a cleaning window is hinged to the outer wall of the sedimentation tank, a handle is rotatably connected to the inner wall of the cleaning window, and a snap-fit ​​component is fixedly installed on the outer wall of the sedimentation tank, which snaps into the handle.

[0018] Compared with existing technologies, the advantages of this concrete cleaning slurry sedimentation equipment are as follows:

[0019] 1. Add flocculant to the sedimentation tank and each feeding structure, then lower the sedimentation tank. As the tank descends, the guide plate enters the water. Once in the water, the reciprocating cylinder rotates the sedimentation tank, causing the guide plate to rotate the water. During this rotation, the sedimentation tank descends again until the feeding structure is at the middle of the water level. At this point, the reciprocating cylinder rotates the sedimentation tank in the opposite direction. During this rotation, the resistance plate experiences water resistance, causing the sealing cover to rotate around the axis. The top and bottom of the feed box are... When opened, the flocculant is released from the inside of the feed box, thus realizing the feeding process. By completing the feeding process in the middle of the water body, the flocculant can diffuse better and come into more direct contact with the suspended solids, promoting their mixing and reaction and improving the effect. At the same time, the flocculant is fed in the opposite direction in the rotating water body, which can generate a certain shear force. This helps to break up large particles or agglomerates in the water, making them easier to contact with the flocculant. In addition, this shear force may also promote the interaction between flocculant molecules and suspended particles, thereby accelerating the flocculation process.

[0020] 2. When the sealing cover is opened, the snap-fit ​​plate connected to the sealing cover via the receiving bracket will be pulled out from the snap-fit ​​groove, thereby releasing the restriction on the push plate. After the elastic element is released from the restriction, it will extend and reset, thereby pushing the push plate to move. The push plate will push the conical plate to move quickly towards the opening. Since the conical plate and the adjusting rod are threadedly connected, the conical plate will rotate during the movement. The rapid movement of the conical plate can push the flocculant to fly out of the material box quickly. On the one hand, it accelerates the diffusion of flocculant to the outside, and on the other hand, it prevents flocculant residue in the material box from affecting the mixing effect and improves the use effect of flocculant.

[0021] 3. As the conical plate moves toward the opening, when the conical plate reaches its maximum value, the receiving plate will collide with the retaining ring. Through the lever principle, with the hinge as the fulcrum, the side of the receiving plate away from the retaining ring will tilt up, thereby ejecting the flocculant on the surface of the receiving plate. This allows the flocculant to spread rapidly in all directions, making the distribution of the flocculant more uniform and enabling it to mix with the water more quickly, further improving the mixing effect.

[0022] 4. After the sewage in the sedimentation tank has finished settling, adjust the position of the sealing baffle and then start the drive motor to lower the sedimentation tank into the sedimentation tank. The sewage that has settled in the sedimentation tank will flow into the sedimentation tank through the overflow trough, thus achieving the first overflow. After the sedimentation work in the sedimentation tank is completed, adjust the height of the sealing baffle again to make the sewage in the sedimentation tank overflow again. The overflowed water flows out through the overflow plate and the guide box. Through two overflow operations and two sedimentation operations, the sewage treatment effect is better.

[0023] 5. The feeding structure in this invention is detachable. By pulling out the pin, the fixing between the plug plate and the plug seat can be released, so that the feeding structure can be removed from the main body of the equipment, thereby facilitating the addition of flocculant.

[0045] The feeding structure 8 also includes a middle plate 809 fixedly installed on the inner wall of the material box 803. A set of elastic elements 810 are fixedly installed on the top and bottom of the middle plate 809. Push plates 811 are provided above and below the middle plate 809. The two push plates 811 are fixedly connected to a set of elastic elements 810 respectively. The outer wall of the push plate 811 is slidably connected to the inner wall of the material box 803. The inner wall of the push plate 811 is provided with a snap-fit ​​groove 812. The outer wall of the sealing cover 806 is fixedly connected to a receiving frame 813. A snap-fit ​​plate 814 is fixedly installed at one end of the receiving frame 813. The snap-fit ​​plate 814 passes through the material box 803 and snaps into the snap-fit ​​groove 812.

[0046] The feeding structure 8 also includes two sets of ball bearings 815 fixedly installed on the inner wall of the push plate 811 and two conical plates 816 slidably connected to the inner wall of the material box 803. The two conical plates 816 are rotatably connected to the two sets of ball bearings 815 respectively. Adjusting rods 817 are fixedly installed at the axial center of the top and bottom of the middle plate 809. The outer walls of the two adjusting rods 817 are threadedly connected to the inner walls of the two conical plates 816 respectively. Multiple hinges 818 are fixedly installed on the top of the conical plates 816. The outer walls of the hinges 818 are... A material support plate 819 is fixedly installed, and multiple partitions 820 are fixedly installed on the top of the material support plate 819. Multiple support blocks are fixedly installed on the top of the conical plate 816. The tops of the multiple support blocks are respectively attached to the bottoms of the multiple material support plates 819. Retaining rings 821 are fixedly installed on the inner walls of the material box 803 near the top and bottom. A pin 822 is inserted into the inner wall of the plug-in seat 801. The plug-in plate 802 is fixedly connected to the plug-in seat 801 through the provided pin 822. A pull block 823 is fixedly installed on the top of the pin 822.

[0047] The internal structure of the stirring structure 9 includes a telescopic vertical rod 901 fixedly installed at the bottom of the sedimentation tank 2. A rotating part 902 is fixedly installed at the bottom of the telescopic vertical rod 901. The bottom of the rotating part 902 is fixedly connected to the bottom of the inner wall of the sedimentation tank 1. Multiple horizontal rods 903 are fixedly installed on the outer wall of the telescopic vertical rod 901. A stirring rod 904 is fixedly installed at the end of the horizontal rod 903 away from the telescopic vertical rod 901.

[0048] In this embodiment, flocculant is added to the interior of the sedimentation tank 2 and each feeding structure 8. Then, the sedimentation tank 2 is lowered. During this descent, a guide plate enters the water. Once the guide plate is in the water, the reciprocating cylinder 7 rotates the sedimentation tank 2, causing the guide plate to rotate the water. As the water rotates, the sedimentation tank 2 lowers again, positioning the feeding structure 8 at the middle height of the water. At this point, the reciprocating cylinder 7 rotates the sedimentation tank 2 in the opposite direction. During this rotation, the resistance plate 807 experiences water resistance, causing the sealing cover 806 to rotate around the shaft 804. The top and bottom of the material box 803 are opened, allowing the flocculant to disperse from inside the material box 803. The flocculant is fed into the water in the middle of the body, allowing for better diffusion and direct contact with suspended solids. This promotes mixing and reaction, improving the flocculant's effectiveness. Reverse feeding of the flocculant in the rotating water generates shear force, which helps break down large particles or agglomerates, making them easier to contact with the flocculant. This shear force also promotes interaction between flocculant molecules and suspended particles, accelerating the flocculation process. When the sealing cover 806 is opened, the snap-fit ​​plate 814, connected to the sealing cover 806 via the receiving bracket 813, is pulled out of the snap-fit ​​groove 812, releasing the push plate. After the elastic element 810 is released from its constraint, it will extend and reset, thereby pushing the push plate 811 to move. The push plate 811 will then push the conical plate 816 to move rapidly toward the opening. Since the conical plate 816 and the adjusting rod 817 are threadedly connected, the conical plate 816 will rotate during the movement. The rapid movement of the conical plate 816 can push the flocculant to fly out of the material box 803 quickly, which accelerates the diffusion of the flocculant to the outside and prevents the flocculant from remaining in the material box 803 and affecting the mixing effect, thus improving the flocculant's effectiveness. During the process of the conical plate 816 moving toward the opening, when the conical plate 816 moves to its maximum value, the receiving plate 819 will collide with it. Upon reaching the retaining ring 821, using the lever principle and with the hinge 818 as the fulcrum, the side of the receiving plate 819 away from the retaining ring 821 will tilt upwards, thereby ejecting the flocculant on the surface of the receiving plate 819, allowing the flocculant to spread rapidly in all directions, thus making the distribution of the flocculant more uniform and enabling it to mix with the water more quickly, further improving the mixing effect. During the rotation of the sedimentation tank 2, the stirring structure 9 will rotate accordingly, thereby stirring the water. In this invention, the feeding structure 8 is detachable. By pulling out the pin 822, the fixation between the plug plate 802 and the plug seat 801 can be released, thereby allowing the feeding structure 8 to be removed from the main body of the equipment, thus facilitating the addition of flocculant.

[0049] Specifically, the outer wall of the sedimentation tank 2 is fitted with an overflow plate 10, and a water guide box 11 is fixedly installed on the outer wall of the overflow plate 10. An overflow trough is opened on the inner wall of the sedimentation tank 2, and a sealing baffle 12 is slidably connected to the inner wall of the overflow trough. A screw is rotatably connected to the inner wall of the sedimentation tank 2, and the outer wall of the screw is threadedly connected to the inner wall of the sealing baffle 12. An adjustment knob 13 is fixedly installed at one end of the screw.

[0050] In this embodiment, after the sewage in the sedimentation tank 1 has finished settling, the position of the sealing baffle 12 is adjusted, and then the drive motor 3 is started to lower the sedimentation tank 2 into the sedimentation tank 1. The sewage that has been settled in the sedimentation tank 1 will flow into the sedimentation tank 2 through the overflow trough, thus achieving the first overflow. After the sedimentation work in the sedimentation tank 2 is completed, the height of the sealing baffle 12 is adjusted again to make the sewage in the sedimentation tank 2 overflow again. The overflowed water flows out through the overflow plate 10 and the water guide box 11. Through two overflow operations and two sedimentation operations, the sewage treatment effect is better.

[0051] Specifically, a bottom plate 14 is fixedly connected to the bottom of the sedimentation tank 1, and a support plate A15 and a support plate B16 are fixedly installed on the top of the bottom plate 14. The support plate A15 and the support plate B16 are fixedly connected to the overflow plate 10 and the water guide box 11, respectively.

[0052] In this embodiment, the overflow plate 10 and the water guide box 11 are fixed by the support plate A15 and the support plate B16, so that the overflow plate 10 can fit in close to the sedimentation tank 2. When the sedimentation tank 2 overflows, the water will flow through the overflow channel to the inside of the overflow plate 10, and then flow out through the water guide box 11.

[0053] Specifically, an outer frame 17 is fixedly installed on the top of the base plate 14, a mounting base 18 is fixedly installed on the top of the outer frame 17, a drive motor 3 is fixedly installed on the inner side of the mounting base 18, and positioning frames 19 are symmetrically fixedly installed on the top of the outer frame 17. The winding wheel 4 is rotatably installed between the inner walls of the two positioning frames 19.

[0054] In this embodiment, the mounting base 18 is used to provide installation conditions for the drive motor 3, and the drive motor 3 is fixed by the mounting base 18. The positioning frame 19 is used to support the winding wheel 4 and ensure the stability of the winding wheel 4 during use.

[0055] Specifically, a connecting frame 20 is fixedly installed on the outer wall of the sedimentation tank 2, and the output shaft of the reciprocating cylinder 7 is fixedly connected to the top of the connecting frame 20.

[0056] In this embodiment, the reciprocating cylinder 7 is connected to the sedimentation tank 2 via the connecting frame 20, so that the reciprocating cylinder 7 can drive the connecting frame 20 to rotate back and forth. The connecting frame 20 is connected to multiple positions of the sedimentation tank 2 from the outside, increasing its stability.

[0057] Specifically, a horizontal plate 21 is fixedly connected to the bottom of the mounting bracket 6, a reciprocating cylinder 7 is fixedly connected to the top of the horizontal plate 21, and sliders 22 are fixedly installed at both ends of the horizontal plate 21. Slide grooves 23 are symmetrically opened on the inner wall of the outer frame 17, and the two sliders 22 are slidably connected to the inside of the two slide grooves 23 respectively.

[0058] In this embodiment, the horizontal plate 21 is fixedly connected to the mounting bracket 6 and the reciprocating cylinder 7, thereby reinforcing the installation of the reciprocating cylinder 7. The horizontal plate 21 is limited by the slider 22 and the slide groove 23 to ensure the stability of the reciprocating cylinder 7 when it starts.

[0059] Specifically, the bottom of the horizontal plate 21 is symmetrically and fixedly connected to the limiting block 24, and the top of the connecting frame 20 is fixedly installed with the limiting ring 25. The inner wall of the limiting ring 25 is slidably connected to the outer wall of the limiting block 24.

[0060] In this embodiment, the limiting block 24 is fixed to the horizontal plate 21, and the limiting ring 25 is fixed to the connecting frame 20. Through the cooperation of the limiting block 24 and the limiting ring 25, the connection between the reciprocating cylinder 7 and the connecting frame 20 is strengthened without affecting the rotation of the connecting frame 20, thus preventing the device from malfunctioning.

[0061] Specifically, the outer wall of the sedimentation tank 1 is hinged with a cleaning window 26, the inner wall of the cleaning window 26 is rotatably connected with a handle 27, and the outer wall of the sedimentation tank 1 is fixedly installed with a snap-fit ​​part 28, which snaps into the handle 27.

[0062] In this embodiment, by rotating the handle 27 to release the engagement with the snap-fit ​​member 28, the cleaning window 26 can be opened, thereby facilitating the cleaning of the interior of the sedimentation tank 1.

[0063] The working principle and usage process of this invention are as follows: After the wastewater in sedimentation tank 1 has settled, the adjusting knob 13 is turned to rotate the screw, causing the sealing baffle 12 to descend. Then, the drive motor 3 is started, driving the winding wheel 4 to rotate, thereby loosening the connecting belt 5 wound on the winding wheel 4, allowing the sedimentation tank 2 to descend into the sedimentation tank 1. The settled wastewater in sedimentation tank 1 flows into the sedimentation tank 2 through the overflow trough, achieving the first overflow. After the overflow ends, the drive motor 3 reverses to raise the sedimentation tank 2. Then, flocculant is added into the sedimentation tank 2 and each feeding structure 8. The sedimentation tank 2 is then lowered again, allowing the guide plate to enter the water. After the guide plate enters the water, the reciprocating cylinder... 7 drives the sedimentation tank 2 to rotate, which in turn causes the guide plate to rotate the water. During the rotation of the water, the sedimentation tank 2 descends again, positioning the feeding structure 8 at the middle height of the water. At this time, the reciprocating cylinder 7 causes the sedimentation tank 2 to rotate in the opposite direction. During this rotation, the resistance plate 807 is resisted by the water, causing the sealing cover 806 to rotate around the rotating shaft 804. The top and bottom of the material box 803 are opened, and the flocculant is released from the inside of the material box 803, thus realizing the feeding operation. By completing the feeding operation in the middle of the water, the flocculant can diffuse better and come into more direct contact with the suspended solids, promoting their mixing and reaction, and improving the effect. At the same time, the flocculant is added in the opposite direction in the rotating water. This can generate a certain shear force, which helps break down large particles or agglomerates in the water, making them easier to contact with the flocculant. Simultaneously, this shear force may also promote the interaction between flocculant molecules and suspended particles, thereby accelerating the flocculation process. When the sealing cover 806 is opened, the snap-fit ​​plate 814 connected to the sealing cover 806 via the receiving bracket 813 is pulled out of the snap-fit ​​groove 812, thus releasing the restriction on the push plate 811. After the elastic element 810 is released, it extends and resets, thereby pushing the push plate 811 to move. The push plate 811 then pushes the conical plate 816 to move rapidly towards the opening. Since the conical plate 816 and the adjusting rod 817 are threadedly connected, the conical plate 816 rotates during movement. The rapid movement of plate 816 propels the flocculant out of container 803 quickly, accelerating its outward diffusion and preventing residue within container 803 that could affect mixing, thus improving flocculant effectiveness. As the conical plate 816 moves towards its opening, when it reaches its maximum value, the receiving plate 819 collides with the retaining ring 821. Through leverage, with hinge 818 as the fulcrum, the side of the receiving plate 819 away from the retaining ring 821 tilts upward, ejecting the flocculant from its surface. This allows the flocculant to spread rapidly in all directions, resulting in a more uniform distribution and faster mixing with the water, further enhancing the mixing effect. During the rotation of sedimentation tank 2…The stirring structure 9 rotates to agitate the water. After the flocculant is mixed, the sedimentation tank 2 rises to perform sedimentation again. After sedimentation is complete, the height of the sealing baffle 12 is adjusted again to allow the wastewater in the sedimentation tank 2 to overflow. The overflowing water flows out through the overflow plate 10 and the guide box 11. Through two overflows and two sedimentations, the wastewater treatment effect is improved. In this invention, the feeding structure 8 is detachable. By pulling out the pin 822, the fixing between the plug plate 802 and the plug seat 801 can be released, allowing the feeding structure 8 to be removed from the main body of the equipment for easy addition of flocculant.
