Description

Technical Field

[0001] The utility model relates to the field of shallow-layer flotation machines, in particular to an angle adjustment mechanism of a sludge treatment device. Background Art

[0002] Shallow flotation machine is a common water purification equipment, mainly composed of a tank body, a sludge treatment device, an overflow regulating device, a rotary water distribution mechanism, etc. It adopts the principle of dissolved air flotation. When working, the rotary water distribution mechanism introduces part of the dissolved air water into the water to be treated to utilize the tiny bubbles released by the dissolved air water, thereby making the suspended matter or oil in the water float to the surface to achieve the purpose of solid-liquid separation. Finally, the sludge floating on the surface is scraped off with the help of the sludge treatment device; the sludge collection device in the prior art is mainly composed of a driving motor, a skimmer and a mud discharge pipe. When the driving motor is working, it will drive the two scroll plates on the skimmer to rotate alternately. Each scroll plate will push the sludge into the skimmer when it rotates across the sewage surface. Finally, The sludge is discharged outwards through the sludge discharge pipe to achieve the scraping of the sludge; in addition, in order to scrape off the sludge from every part of the sewage surface, the skimmer will also rotate around the pool body with the help of a matching connecting mechanism to achieve revolution; however, since the inclination of the skimmer and the sludge discharge pipe are small and fixed, and the sludge flow is poor, if only relying on the inclination of the skimmer and the sludge discharge pipe, the sludge flow rate is slow, resulting in the sludge in the skimmer and the sludge discharge pipe cannot be quickly emptied, so it is easy to get blocked. The only way to avoid blockage is to reduce the rotation speed of the skimmer to allow the sludge enough time to flow. However, this results in a low treatment efficiency of the shallow flotation machine, and each treatment process takes a long time, which needs further improvement. Utility Model Content

[0008] Preferably, a positioning hole distributed radially along the annular guide tube is opened on one side of the lower end of the lifting column, and the traction bolt is inserted into the positioning hole. A first nut is also threaded on the threaded portion of the traction bolt. The head of the traction bolt and the first nut are both pressed against the outer wall of the lifting column and are respectively located outside the openings at both ends of the positioning hole.

[0009] Preferably, two second nuts are threadedly mounted on the threaded portion of the traction bolt and are located on both sides of the wear-resistant sleeve.

[0025] Two second nuts 8 are threadedly mounted on the threaded portion of the traction bolt 3 and are located on both sides of the wear-resistant sleeve 7.

[0030] A first connecting hole 24 is defined in the connecting block 23 , and correspondingly, a concentrically distributed second connecting hole 102 is defined on both inner walls of the connecting groove 101 . Pins 10 are inserted into the first connecting hole 24 and the two second connecting holes 102 .

[0031] Working principle:

[0032] like Figure 4 As shown, the main structure of the shallow flotation machine mainly consists of a cylindrical purification tank 11, a cylindrical isolation tank 12 concentrically arranged inside the cylindrical purification tank 11, and a cylindrical collection tank 13 concentrically arranged inside the cylindrical isolation tank 12. When the shallow flotation machine is working, sewage exists between the cylindrical purification tank 11 and the cylindrical isolation tank 12. The above structure and principle are all existing technologies.

[0033] A sludge collecting mechanism is provided above the cylindrical purification tank 11, the cylindrical isolation tank 12 and the cylindrical collection tank 13. The sludge collecting mechanism is mainly composed of a rotary frame 14, a drive motor 15, a skimming scoop 16 and a sludge discharge pipe 17. The inner side of the rotary frame 14 is rotatably connected to the top opening of the cylindrical isolation tank 12, and the outer side of the rotary frame 14 is rotatably connected to the top opening of the cylindrical purification tank 11; the drive motor 15, the skimming scoop 16 and the sludge discharge pipe 17 are sequentially arranged inside the rotary frame 14 from the outside to the inside, and the rotating shaft of the drive motor 15 is arranged in the direction of the skimming scoop 16 and fixed to the skimming scoop. At the center of the outer end of the scoop 16, the mud discharge pipe 17 is concentrically inserted into the inner end of the skimming scoop 16 and is interconnected with the interior of the skimming scoop 16; a wheel frame 19 that can revolve around the cylindrical isolation tank 12 is also provided above the top opening of the cylindrical isolation tank 12, and two rotatable and symmetrically distributed rollers 18 are also provided on the wheel frame 19. The middle part of the mud discharge pipe 17 is erected between the two rollers 18 so that the mud discharge pipe 17 can follow the rotation of the skimming scoop 16 while obtaining the support force of the wheel frame 19; the end opening of the mud discharge pipe 17 is inclined above the top opening of the cylindrical collecting tank 13. The above structure and principle are all existing technologies.

[0034] The annular guide tube 5 is concentrically fixed at the top opening of the cylindrical purification tank 11, and then the rotating frame 14 is placed above the cylindrical purification tank 11, the cylindrical isolation tank 12 and the cylindrical collection tank 13, and the threaded end of the traction bolt 3 is passed through the corrugated guide groove 51 along the radial direction of the annular guide tube 5 and extended into the interior of the annular guide tube 5; then the support seat 9 is fixed to the outer inner wall of the rotating frame 14, and then the top of the connecting seat 1 is fixed to the drive motor 15 so that the drive motor 15 is supported; finally, according to the same principle, the outer side of the rotating frame 14 is rotatably connected to the top of the annular guide tube 5, and then the inner side of the rotating frame 14 is rotatably connected to the top opening of the cylindrical isolation tank 12, so that the rotating frame 14 can revolve around the cylindrical purification tank 11, the cylindrical isolation tank 12 and the cylindrical collection tank 13.

[0035] The driving motor 15 is started to rotate its rotating shaft, thereby driving the skimmer 16 and the mud discharge pipe 17 to rotate together. When the skimmer 16 rotates, the two centrally symmetrically distributed leaf plates 161 on the skimmer 16 will alternately roll across the sewage surface. When the outer edge of any leaf plate 161 passes through the sewage surface, the mud floating on the sewage surface will be scooped into the interior of the skimmer 16; since the inner and outer walls of each leaf plate 161 are conical surfaces, in order to ensure that the leaf plate 161 can scoop up the mud to the greatest extent, the outer edge of the leaf plate 161 must be adjusted to a horizontal state to match the sewage surface, so that the driving motor 15, the skimmer 16 and the mud discharge pipe 17 are all in an inclined state with a low inside and a high outside, so that the sludge inside the skimmer 16 can flow out into the cylindrical collection tank 13 through the mud discharge pipe 17; and the purpose of the revolution is to enable the skimmer 16 to collect the sludge at every part of the sewage surface. The above structure and principle are all existing technologies.

[0036] However, since the slope of the skimmer 16 is small and the sludge flow is poor, the sludge collected by the skimmer 16 the previous time has not yet completely flowed out, and the sludge collected the next time has to enter again, which makes it impossible for the skimmer 16 to quickly empty the sludge; and the function of the utility model is that: when the driving motor 15, the skimmer 16 and the mud discharge pipe 17 rotate together with the rotary frame 14, the lifting column 2 will rotate together with the rotary frame 14 with the help of the limit sleeve 4, thereby driving the traction bolt 3 to rotate synchronously, but because the threaded end of the traction bolt 3 passes through the corrugated guide groove 51 along the radial direction of the annular guide tube 5 and extends into the inner part of the annular guide tube 5 Therefore, the traction bolt 3 will fluctuate continuously up and down along the direction of the corrugated guide groove 51 during revolution. Since the outer height of the rotary frame 14 remains unchanged, and since the connecting seat 1 can rotate on the vertical diameter plane at any position of the annular guide tube 5, the traction bolt 3 will drive the drive motor 15 to fluctuate continuously up and down with the help of the lifting column 2 and the connecting seat 1, thereby continuously changing the inclination angle of the skimmer 16 and the mud discharge pipe 17; the lateral spacing of each crest and each trough of the corrugated guide groove 51 is designed to cooperate with the rotation speed of the drive motor 15, so that the following effects can be achieved: when any leaf plate 161 needs to When scooping sludge, the traction bolt 3 is exactly at the trough position, so that the outer edge of the above-mentioned rolling blade 161 is in a horizontal position; when the rolling blade 161 has scooped out the sludge, the traction bolt 3 gradually rises along the wave-shaped guide groove 51 during the revolution, so that the inclination angle of the skimming scoop 16 and the mud discharge pipe 17 continues to increase. When the traction bolt 3 reaches the peak position, the inclination angle of the skimming scoop 16 and the mud discharge pipe 17 reaches the maximum, so that the sludge in the skimming scoop 16 and the mud discharge pipe 17 can be quickly emptied; when the other rolling blade 161 gradually turns to the sewage surface to prepare for scooping sludge, the traction bolt 3 gradually moves downward. When the traction bolt 3 reaches the next trough position, the outer edge of the other rolling blade 161 is also in a horizontal position to facilitate scooping sludge, thereby forming a cycle; since the mud discharge pipe 17 is installed between the two rollers 18, the upper and axial directions of the mud discharge pipe 17 are not restricted and the position can be changed at will. Therefore, when the inclination angle of the mud discharge pipe 17 is constantly changing, the mud discharge pipe 17 can always be installed between the two rollers 18 at different inclination angles to maintain the smoothness of the rotation. When the inclination angle of the mud discharge pipe 17 changes, the axial direction of the mud discharge pipe 17 will automatically adjust adaptively.

[0037] The setting of the wear-resistant sleeve 7 can prevent the traction bolt 3 from directly contacting the inner wall of the corrugated guide groove 51, thereby effectively preventing the wear of the traction bolt 3 and reducing the friction between the two; if the wear-resistant sleeve 7 is damaged, just replace the wear-resistant sleeve 7; when replacing, first use the rotating frame 14 to rotate a second nut 8 located inside the annular guide tube 5 to the position of any through hole 52, and then use a tool to pass through the above-mentioned through hole 52 and extend into the inside of the annular guide tube 5 to remove the above-mentioned second nut 8, and then take the wear-resistant sleeve 7 outward through the above-mentioned through hole 52, and finally replace it with a new wear-resistant sleeve 7 and reinstall the removed second nut 8 according to the same principle.

[0038] The utility model can repeatedly change the inclination angle of the driving motor 15, the skimmer 16 and the mud discharge pipe 17 in accordance with the rotation speed of the driving motor 15, so that the two rolling blades 161 on the skimmer 16 can automatically restore to a horizontal state when scraping sludge, and when discharging sludge, the inclination angle of the skimmer 16 and the mud discharge pipe 17 reaches the maximum to effectively accelerate the sludge flow rate, and then quickly empty the sludge in the skimmer 16 and the mud discharge pipe to avoid blockage, thereby shortening the sludge emptying time and improving the processing efficiency of the shallow flotation machine.
