DETAILED DESCRIPTION

[0031] The embodiment of the present invention provides a micro-bubble generating mechanism of an air flotation water purification device, such as Figure 1-7As shown, it includes a water purification tank body 1, which is filled with sewage, and a disc 2 is arranged in the water purification tank body 1, and the disc 2 is suspended in the sewage of the water purification tank body 1.

[0032] An outer layer tape 3, a middle layer tape 4 and an inner layer tape 5 are arranged in the chamber 1 21. The middle layer tape 4 is located in the outer layer tape 3, and the inner layer tape 5 is located in the middle layer tape 4. Three groups of traction rollers 23 are arranged in the chamber 1 21. The three groups of traction rollers 23 correspond to the three tapes one by one respectively. The traction rollers 23 cooperate with the tape transmission, and the rotation of the traction rollers 23 drives the tape to rotate.

The diameter of pore 1 31 is smaller than that of pore 2 41 , and the diameter of pore 2 41 is smaller than that of pore 3 51 .

[0034] It also includes a trapezoidal block 6, the side of the trapezoidal block 6 is welded to the inner wall of the chamber 21, an air groove 64 is provided on the top of the trapezoidal block 6, the interior of the trapezoidal block 6 is hollow, a plurality of air cylinders 7 are pivotally connected to the trapezoidal block 6, a plurality of holes are provided on the rod of the air cylinder 7, a docking channel is provided on the disc 2, an air delivery hose 9 is fixedly installed at the aggregation end of the docking channel, the air delivery hose 9 extends to the outside of the water purification tank body 1, and the branch end of the docking channel is connected to the air cylinder 7.

[0035] The chamber 1 21 is filled with liquid oil 10. The gas cylinder 7 is in a fast rotating state, and air is released from the holes of the gas cylinder 7, and the gas is suspended in the liquid oil 10 in the form of bubbles. At the same time, the cover plate 27 is opened, and then with the help of buoyancy, the bubbles pass through the inner tape 5, the middle tape 4, and the outer tape 3 in sequence, and the bubbles are finally released into the water purification tank body 1.

[0036] A plurality of ropes 11 are fixedly bound to the bottom of the disc 2 , and the lower ends of the ropes 11 are fixedly bound to the inner wall of the bottom of the water purification tank body 1 .

[0037] A semipermeable membrane 26 is fixedly installed at the upper opening of the chamber 1 21, and the semipermeable membrane 26 only allows gas to pass through.

[0038] It also includes a horizontal plate 1 24 and a horizontal plate 25. The sides of the horizontal plate 1 24 and the horizontal plate 25 are welded to the inner wall of the chamber 1 21. The horizontal plate 1 24 is provided with a through gas delivery channel 1 241, and the horizontal plate 25 is provided with a through gas delivery channel 2 251. The gas delivery channel 1 241, the gas delivery channel 2 251 and the gas groove 64 are aligned.

[0039] When air is input into the air cylinder 7 through the air delivery hose 9, the air cylinder 7, the outer tape 3, the middle tape 4, and the inner tape 5 rotate respectively, and the air cylinder 7 rotates intermittently to spray out bubbles, which float up and are cut through the inner tape 5, the middle tape 4, and the outer tape 3 to form tiny bubbles.

[0040] A counterweight 271 is welded to the top of the cover plate 27, and a chamber 22 is opened in the disc 2. A winding rod 29 is pivotally connected in the chamber 22. A steel wire 28 is welded to the shaft of the winding rod 29. The steel wire 28 extends to the outside of the disc 2 away from one end of the winding rod 29 and is welded to the counterweight 271. A pressure relief hole 221 connected to the outside is opened at the bottom of the chamber 22.

[0041] The water purification tank body 1 is also fixedly installed with a pressurizing device. According to the hydraulic transmission principle, the pressure transmitted to various parts of the surface of the object through the water body is equal. If the object is compressible, when the external air pressure increases, the object in the water will also be compressed, the drainage volume will decrease, the buoyancy will decrease, and the object will change from a suspended state to a sinking state.

[0042] A touch switch 12 is fixedly installed on the inner wall of the water purification tank body 1. When the disc 2 drops to the lowest point, it can touch the touch switch 12. A warning light 13 is fixedly installed outside the water purification tank body 1. The touch switch 12 is electrically connected to the warning light 13.

[0043] The above-mentioned disc 2 is made of rubber. After the sewage is poured into the water purification tank body 1, some air is reserved at the top of the interior. Then, air is introduced from the top of the water purification tank body 1 to apply pressure. This is a conventional technical means. Working principle: When the pressure increases to the specified requirement, the water in the second chamber 22 is squeezed out, the volume of the entire disc 2 is reduced, the disc 2 sinks and contacts the touch switch 12, so that the warning light 13 lights up. This indicates that the internal pressure of the water purification tank body 1 has reached the specified standard and air can be transported.

[0044] The horizontal plate 1 24 is between the outer tape 3 and the middle tape 4, the horizontal plate 25 is between the middle tape 4 and the inner tape 5, the top of the trapezoidal block 6 is in close contact with the inner tape 5, the bottom of the horizontal plate 25 is in contact with the inner tape 5, the top of the horizontal plate 25 is in contact with the middle tape 4, the bottom of the horizontal plate 1 24 is in contact with the middle tape 4, and the top of the horizontal plate 1 24 is in contact with the outer tape 3.

[0045] Since the outer layer adhesive tape 3 is in a tight state, there is no possibility of air bubble leakage. Further, the adhesive tape is in close contact with the horizontal plate 2. The liquid oil 10 plays a role of lubrication.

[0046] A gear 8 is fixedly mounted at the center of the trapezoidal block 6, and a tooth groove 71 is provided around the center of the rod of the air cylinder 7. The gear 8 is meshed with the tooth groove 71, and the rotation of the gear 8 drives the air cylinder 7 to rotate.

[0047] The trapezoidal block 6 is symmetrically provided with grooves 61, which are located at the front and rear sides of the gear 8, and the air groove 64 is connected with the groove 61. The inner wall of the groove 61 is provided with a slide rail 62, and a driving part is slidably fitted in the slide rail 62. The driving part is fixedly provided with a paddle 63, and the air cylinder 7 has a hole extending into the groove 61. The groove 61 is also filled with liquid oil 10.

[0048] The driving unit drives the paddle 63 to move along the slide rail 62 , and the paddle 63 pushes the bubbles so that the bubbles float to the side of the groove 61 , so that bubbles pass through each gas groove 64 to a certain extent.

[0049] The diameter of pore 1 31 is 20 microns, the diameter of pore 2 41 is 40 microns, and the diameter of pore 3 51 is 80 microns.

[0050] The diameters of each group of traction rollers 23 are different.

[0051] There are wrinkles on the surface of the gas delivery hose 9 to facilitate the expansion and contraction of the gas delivery hose 9.

[0052] The gear 8, winding rod 29 and traction roller 23 are all driven by motors, which are conventional technical means and will not be described in detail.

[0053] In summary, the micro-bubble generating mechanism of the air flotation water purification device is that a disc 2 is suspended in the water purification tank 1, and pressure is applied to the tank. The disc 2 is subjected to the pressure and its volume becomes smaller, and at this time, the disc 2 sinks. Air is transported into the disc 2. A trapezoidal block 6 is provided in the disc 2, and an air cylinder 7 is provided in the trapezoidal block 6. Air is ejected from the rotating air cylinder 7 to form bubbles, and then the bubbles are cut into tiny bubbles that meet the indicators through the cooperation of the outer tape 3, the middle tape 4, and the inner tape 5. This solves the problem of large-volume bubbles in the traditional water purification process, which affects the air flotation separation effect.
