Description

Technical Field

[0001] The invention belongs to the technical field of air flotation machines, in particular to a buoy scraping air flotation machine. Background Art

[0002] The flotation machine is a water treatment equipment that uses a dissolved air system to generate a large number of tiny bubbles in the water, causing the air to attach to the suspended particles in the form of highly dispersed tiny bubbles, resulting in a state where the density is less than that of water. The buoyancy principle is used to make the air float on the water surface, thereby achieving solid-liquid separation.

[0003] Since the flotation machine is mainly used to treat large amounts of grease in industrial wastewater and sewage, the use of a scraper circulating rotation method can easily cause the foam on the sewage surface to easily pass through the side of the scraper. The floating drum rotates the scraper to clean the foam. The rotating joint position on the side of the float is prone to the accumulation of scum, which makes it increasingly difficult for the float to rotate, so it needs to be improved.

[0015] The beneficial effects of the present invention are as follows:

[0016] 1. During operation, the device scrapes away the floating foam on the sewage surface through the bent filter plates on both sides to achieve the effect of cleaning the suspended particles in the water body. Since the scraper is used in a circular rotation mode, the floating foam on the sewage surface is easy to pass through the side parts of the scraper, and then the scum is gathered at the rotating joints on the sides of the outer cylinder shell, thereby affecting the rotation of the scraper equipment. Therefore, self-rotating side sleeves are provided on both sides to continuously disperse the accumulated scum through the jet end, thereby avoiding the problem that the accumulation of scum makes the rotation of the outer cylinder shell more and more difficult.

[0017] 2. The scraping equipment can detect the position of the sewage level through the inflatable outer pad set on the outer surface, and thus cooperate with the adjustment work of the heightening bottom column, so that the bent filter plate can scrape away the scum above the liquid surface during the rotation, thereby performing adaptive adjustment work for sewage of different capacities to prevent the problem that the scraping equipment is far away from the liquid level and cannot work normally due to the reduction of sewage water volume.

[0018] 3. During sewage treatment, the side push box on the left side will push the wall push plate back and forth through the horizontal push rod to push the sewage to the right. At this time, the scum on the upper surface of the sewage will float to the right again and be cleaned by the scraping equipment, thereby preventing the scum from gathering in the cleaning dead corner on the right side of the scraping equipment.

[0019] 4. By having the bent filter plate hit the residue holding component, the residue scraped off the inner wall of the bent filter plate is poured into the interior of the horizontal connecting plate, thereby achieving the effect of clearing the bent filter plate, and the adsorption plate can clear the filter mesh of the bent filter plate by means of side jet flow, thereby further cleaning the residual residue inside the bent filter plate. When the bent filter plate hits the inner wall of the horizontal connecting plate, it will stop moving urgently and generate vibration force, so it can promote the shaking off of the residue on the inner wall of the bent filter plate by adding vibration, thereby preventing the residue from adhering tightly to the inner wall of the bent filter plate and being difficult to pour onto the horizontal connecting plate.

Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0030] Example 1, please refer to Figure 1-Figure 6 The present invention provides a technical solution: a buoy scraper flotation machine, comprising a treatment box 1, side spray components 3 are symmetrically arranged on the front and rear sides of the outer surface of the treatment box 1, a scraper device 2 is rotatably connected to the upper part of the treatment box 1, and a flow-pushing component 4 is arranged on the left side of the treatment box 1;

[0031] The scraping device 2 includes an outer cylinder shell 21, and an inserting inner cylinder 22 is fixedly connected to the axis center of the inner wall of the outer cylinder shell 21. The outer surface of the inserting inner cylinder 22 is evenly provided with a pressure-sensing box 23, and the end of the pressure-sensing box 23 away from the inserting inner cylinder 22 is fixedly connected to an inflatable outer cushion 24. After the inflatable outer cushion 24 contacts the water surface, it will be squeezed due to the buoyancy of the water surface, thereby triggering the pressure-sensing box 23. Sliding push rods 25 are symmetrically arranged on the upper and lower sides of the outer surface of the inserting inner cylinder 22, and the end of the sliding push rod 25 away from the inserting inner cylinder 22 is fixedly connected to an inner sliding push plate 26. Compression springs 27 are symmetrically arranged on both sides of the outer surface of the inner sliding push plate 26. A bent filter plate 28 is fixedly connected to the middle part of the outer surface of the inner sliding push plate 26. The sliding push rod 25 can pull the bent filter plate 28 to slide by actively extending and retracting.

[0032] The side spray component 3 includes a torque motor 31, a height adjustment bottom column 32 is fixedly connected to the bottom of the outer surface of the torque motor 31, a side sleeve 33 is fixedly connected to the outer surface of the output shaft of the torque motor 31, and the inner cavity of the side sleeve 33 is evenly provided with jet ends 35. An embedded turntable 36 is rotatably connected to the inner cavity of the side sleeve 33 near the axis center of one side of the torque motor 31 through a rotating groove, and embedded inserts 37 are symmetrically provided on the left and right sides of the inner cavity of the embedded turntable 36. The end of the embedded insert 37 away from the embedded turntable 36 is fixedly connected to a side pressure pump 38. The side pressure pump 38 can inflate the interior of the side sleeve 33 so that the side sleeve 33 can blow away the scum accumulated on the front and rear sides of the side spray component 3 through the jet end 35, and a plug-in connecting rod 39 is fixedly connected to the axis center of the outer surface of the side pressure pump 38.

[0033] There are two side spray components 3. The bottom end of the height-adjusting bottom column 32 is fixedly connected to the outer surface of the processing box 1. The outer surface of the output shaft of the torque motor 31 is fixedly connected to the inner wall of the plug-in inner cylinder 22. The side of the outer surface of the side sleeve 33 away from the torque motor 31 is rotatably connected to the outer surface of the outer cylinder shell 21 through a circular rail groove.

[0034] An axial rotating cylinder 34 is fixedly connected to the axis center of the inner wall of the side sleeve 33, and one end of the jet end 35 away from the axial rotating cylinder 34 extends to the outside of the side sleeve 33. The inner wall of the axial rotating cylinder 34 is rotatably connected to the outer surface of the output shaft of the torque motor 31 through a rotating column. The axial rotating cylinder 34 can drive the side sleeve 33 to rotate relative to the torque motor 31 through the rotating column on the inner wall, thereby changing the jet position of the jet end 35.

[0035] There are four inflatable outer cushions 24, the outer surfaces of which are fixedly connected to the outer surface of the outer tube shell 21. There are two bent filter plates 28, and filter mesh holes are evenly arranged on the outer surfaces of the bent filter plates 28. The outer surface of the pressure sensing box 23 is fixedly connected to the outer surface of the plug-in inner tube 22.

[0036] The processing box 1 includes a containing box body 11, a drainage port is provided on the left side of the bottom of the inner cavity of the containing box body 11, a gas dissolving component 12 is fixedly connected to the bottom of the inner wall of the containing box body 11, drainage ports 13 are evenly arranged on the right side of the inner cavity of the containing box body 11 through the through opening, waterproof baffles 14 are symmetrically arranged on the front and back sides of the inner wall of the containing box body 11, guide rails 15 are symmetrically arranged on the left and right sides of the waterproof baffles 14, the guide rails 15 are embedded in the interior of the containing box body 11, and are used to guide the plug-in connecting rod 39 to perform vertical sliding movement, and socket slides 16 are symmetrically arranged on the front and back sides of the inner cavity of the containing box body 11.

[0037] The top of the inner wall of the sleeve slide 16 is rotationally connected to the side of the outer surface of the output shaft of the torque motor 31 away from the side sleeve 33, the outer surface of the guide rail 15 is fixedly connected to the inner wall of the accommodating box 11 through a vertical slide groove, the end of the plug-in connecting rod 39 away from the side pressure pump 38 is slidably connected to the inner wall of the guide rail 15, and the outer surface of the plug-in connecting rod 39 is slidably connected to the inner cavity of the accommodating box 11 through a vertical slide groove.

[0038] When the device is used for operation, sewage is injected into the interior of the containing box 11 through the drainage port 13 on the right side, and then the air dissolving component 12 at the bottom generates fine bubbles, so that the air is attached to the suspended particles in the form of highly dispersed tiny bubbles, and the suspended particles are gathered on the water surface. Subsequently, the outer cylinder shell 21 and the plug-in inner cylinder 22 at the top rotate counterclockwise under the rotation of the torque motor 31, and the water gathered on the sewage surface is scooped out through the bent filter plates 28 on both sides of the outer surface. The sewage will flow into the containing box 11 through the mesh of the bent filter plate 28, and the foam impurities will remain on the inner wall of the bent filter plate 28.

[0039] After the water enters the containing box 11, it is necessary to ensure that the scraper device 2 is at the height of the horizontal plane. At this time, raising the bottom column 32 will move the scraper device 2 downward by driving the torque motor 31 to descend, and gradually approach the horizontal plane below. When the lower part of the outer cylinder shell 21 is completely immersed in water, the inflatable outer pads 24 on both sides below will be immersed in the sewage, causing the reaction force generated by the buoyancy to squeeze the inflatable outer pads 24, thereby triggering the internal pressure sensing box 23, indicating that the height adjustment of the scraper device 2 is completed and the scraping work can be carried out normally.

[0040] When the outer cylinder shell 21 rotates, the side sleeves 33 on both sides can independently rotate relative to the long rotating shaft of the torque motor 31 under the control of the inner wall axis rotating cylinder 34, and when the side sleeves 33 rotate, they will rotate relative to the embedded turntable 36, that is, the embedded turntable 36 can always remain in a relatively static state, and the side pressure pumps 38 on both sides pressurize the inside of the side sleeves 33 through the embedded insert tubes 37, and blow air into the sewage through the jet ends 35 of the side sleeves 33, so as to blow away the scum gathered on the front and rear sides of the outer cylinder shell 21, so as to prevent the scum from accumulating and causing difficulty in rotating the outer cylinder shell 21.

[0041] The side sleeve 33 can slide up and down with the torque motor 31, driving the side pressure pumps 38 on both sides to move synchronously along the inner wall of the guide slide rail 15. Since the sleeve slide 16 always slides against the inner wall of the containing box 11 and closes the reserved slide groove of the containing box 11, the waterproof baffle 14 further prevents the internal sewage from seeping out. Therefore, during the up and down adjustment of the scraping equipment 2, the sewage inside the containing box 11 will not seep out.

[0042] Example 2, please refer to Figure 1-Figure 8 The present invention provides a technical solution: on the basis of Example 1, the flow pushing component 4 includes a fixed bottom plate 41, the top of the fixed bottom plate 41 is fixedly connected to a side push box 42, the right side of the outer surface of the side push box 42 is evenly provided with sliding push rods 25, the right end of the sliding push rod 25 is fixedly connected to a wall push plate 44, and the top of the wall push plate 44 is provided with a slag holding component 5.

[0043] The slag holding component 5 includes a vertical thick plate 51, and a horizontal connecting plate 54 is slidably connected to the inner part of the vertical thick plate 51. An adsorption plate 55 is fixedly connected to the left side of the horizontal connecting plate 54, and air jets 53 are evenly opened on the right side of the inner cavity of the adsorption plate 55. Auxiliary wheels 52 are symmetrically arranged on the left side of the outer surface of the vertical thick plate 51. The auxiliary wheels 52 can drive the adsorption plate 55 to slide left and right relative to the vertical thick plate 51 in a fixed state. The outer surface of the auxiliary wheel 52 is rollingly connected to the outer surface of the adsorption plate 55. The cross-section of the end of the adsorption plate 55 is the same as the cross-section on the left side of the horizontal connecting plate 54, and the air jet 53 passes through the left side of the inner cavity of the horizontal connecting plate 54.

[0044] The front and rear sides of the lower surface of the vertical thick plate 51 are both slidably connected to the upper surface of the containing box 11, the upper surface of the vertical thick plate 51 is fixedly connected to the top of the wall-adhering push plate 44, the outer surface of the wall-adhering push plate 44 is slidably connected to the left side of the inner wall of the containing box 11, and the outer surface of the sliding push rod 25 is slidably connected to the left side of the inner cavity of the containing box 11 through the through opening.

[0045] When sewage treatment is being carried out, the side push box 42 located on the left side will reciprocately push the wall push plate 44 through the horizontal push rod 43, pushing the sewage to the right. At this time, the scum on the upper surface of the sewage will float to the right again, and the cleaning work will be carried out through the scraping device 2, thereby preventing the scum from gathering in the cleaning dead corner on the right side of the scraping device 2.

[0046] After continuous rotation, a large amount of scum is scraped off the inner wall of the bent filter plate 28. At this time, the wall-attached push plate 44 can be pushed to the right, and the rotating bent filter plate 28 will hit the horizontal connecting plate 54 on the left, pouring the residue on the inner wall into the interior of the horizontal connecting plate 54, and then the adsorption plate 55 will spray air to the right through the air jet 53 to blow out the scum in the mesh of the bent filter plate 28, and it will also fall into the interior of the horizontal connecting plate 54 to complete the work of collecting the scum, and the bent filter plate 28 on the other side will also be vibrated due to the impact force, but its bent part faces upward, so the residue on the inner wall will not fall into the sewage.

[0047] The auxiliary rotating wheel 52 can slide the adsorption plate 55 so that the adsorption plate 55 and the fixed vertical thick plate 51 can slide relative to each other. At this time, the horizontal connecting plate 54 can not hinder the bending filter plate 28, and the outer cylinder shell 21 can rotate normally.

[0048] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
