Description

Technical Field

[0001] The utility model relates to the technical field of aerator production, in particular to a cyclone type microporous aerator. Background Art

[0002] With the rapid development of social economy, sewage treatment has received more and more attention, and aerators are the most commonly used equipment in the field of sewage treatment. Aerators are essential equipment for aeration and oxygenation of water supply and drainage. In sewage treatment, aerobic reactions are usually required to remove organic matter in sewage. It is a treatment device that uses aerobic microorganisms in sewage to digest and degrade organic matter in sewage in the presence of free oxygen, making it stabilized and harmless. Aerators provide oxygen for aerobic reactions.

[0003] The utility model with authorization announcement number CN210214914U provides a cyclone aerator that is easy to fix and install. By aerating the water flow twice, oxygen can be evenly dissolved in the water. The spiral blades are used for rotation to guide the water flow and produce a cyclone state. The overall use is convenient and the cost is low.

[0004] When the cyclone aerator proposed above aerates the water through the aeration mixing strip, the stationary aeration mixing strip cannot evenly pump air into the water at the same height, resulting in uneven dissolved oxygen content in the water. At the same time, a large number of bubbles are generated when aerating the water, and the bubbles prevent the oxygen inside them from dissolving in the water. The above patent cannot reduce the number of bubbles, so a large amount of oxygen is not dissolved in the water and is directly discharged through the output port. In view of this, we propose a cyclone microporous aerator. Summary of the Invention

[0005] The purpose of the utility model is to provide a cyclonic microporous aerator to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, one of the purposes of the present invention is to provide a cyclone-type microporous aerator, comprising a cylinder, the inner wall of the cylinder is fixedly connected to two support frames, the two support frames are aligned up and down, and the side walls of the two support frames are rotatably connected to a shaft tube, the upper end of the shaft tube is provided with an air intake assembly, and the air intake assembly is used to inject air into the shaft tube, and the lower end of the shaft tube is provided with a driving assembly, and the driving assembly is used to drive the shaft tube to rotate. The outer wall of the shaft tube is located on the side where the two support frames are away from each other, and a plurality of hollow plates are fixedly connected to the annular array, and a plurality of through holes are opened on the side walls of the hollow plates, and the outer wall of the shaft tube is fixedly connected to a spiral blade at a position between the two support frames, and a reciprocating mechanism is provided on the lower side of the upper support frame, and a plurality of bubble nails are provided in an annular array between the reciprocating mechanism and the spiral blades. When the shaft tube drives the hollow plate to rotate, the reciprocating mechanism drives the bubble nails to move back and forth vertically.

[0007] As a further improvement of the present technical solution, the reciprocating mechanism includes several concentrically arranged positioning rings, the upper ends of several of the piercing nails are respectively fixedly connected to the lower surfaces of several positioning rings, the top annular array of the positioning rings is fixedly connected to several vertical rods, the side wall annular array of the support frame is provided with several hydrophobic holes, the upper ends of the vertical rods pass through the hydrophobic holes and extend to the top of the support frame, the upper ends of the vertical rods are fixedly connected to a ball head, and a spring is provided on the outer movable sleeve of the vertical rod, the two ends of the spring are respectively fixedly connected to the support frame and the positioning ring, when the ball head moves downward, the vertical rod drives the positioning ring and the piercing nail to move downward synchronously, and the spring is elastically stretched.

[0008] As a further improvement of the present technical solution, the ball head is higher than the lower surface of the hollow plate located above. When the rotating hollow plate contacts the ball head, the hollow plate presses the ball head downward, causing the spring to elastically stretch. When the rotating hollow plate loses contact with the ball head, the spring rebounds and drives the positioning ring and the piercing nail to move upward.

[0009] As a further improvement of the present technical solution, the air intake assembly includes a sleeve rotatably connected to the upper end of the shaft tube, one side of the sleeve is fixedly connected to an air intake pipe, and one end of the air intake pipe passes through the side wall of the cylinder and extends out.

[0010] As a further improvement of the present technical solution, the drive assembly includes a base frame fixedly connected to the lower surface of the cylinder, and a waterproof motor is fixedly connected to the bottom surface inside the base frame. The output shaft of the waterproof motor passes through the lower side wall of the cylinder and is coaxially fixedly connected to the shaft tube.

[0011] As a further improvement of the present technical solution, a water inlet pipe is fixedly connected to one side of the cylinder, the hollow plate located below is located above the water inlet pipe, the cylinder is set with an opening at the top, and the opening of the cylinder is set as an output port.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. When air is pumped into the shaft tube through the air inlet assembly, the air is discharged from the inside of the hollow plate through the through holes. By driving the shaft tube to rotate several hollow plates, the through holes on the hollow plates are fully in contact with the water at the same height, so that oxygen can be dissolved in the water more evenly, thereby increasing the dissolved oxygen content in the water.

[0014] 2. In this cyclone microporous aerator, when the shaft tube drives the hollow plate to rotate, the reciprocating mechanism drives several bubble nails to move vertically back and forth, so that the bubble nails puncture some bubbles in the water in the cylinder, allowing more oxygen to dissolve in the water, further increasing the dissolved oxygen content in the water in the cylinder.

[0026] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention. Example

[0027] See also Figure 1-Figure 2The air inlet pipe 3 is provided with an air inlet pipe 31, and the air inlet pipe 3 is provided with an air inlet pipe 32. The air inlet pipe 3 is provided with an air inlet pipe 32. The air inlet pipe 3 is provided with an air inlet pipe 32. The air inlet pipe 3 is provided with an air inlet pipe 32. The air inlet pipe 3 is provided with an air inlet pipe 32. The air inlet pipe 3 is provided with an air inlet pipe 32. The end of the pipe 11 away from the cylinder 1 is connected to an external water pump, and the hollow plate 31 located below is located above the water inlet pipe 11. The cylinder 1 is set as an opening at the top, and the opening of the cylinder 1 is set as an output port. Water is pumped into the interior of the cylinder 1 through the water inlet pipe 11. After the water fills the cylinder 1, the water flows out through the opening. During the process of conveying water by the water inlet pipe 11, air is pumped into the shaft tube 3 through the air intake component, and the air discharged from the hollow plate 31 through the through hole 32 is mixed with the water, thereby increasing the content of the water flowing out of the cylinder 1. In the process of pumping water and air, the shaft tube 3 is driven to rotate by the driving assembly, so that the shaft tube 3 drives the hollow plate 31 and the spiral blades 35 to rotate. When the hollow plate 31 rotates, the through hole 32 is driven to fully contact with the water body at the same height, so that oxygen can be dissolved in the water more evenly. When the spiral blades 35 rotate, a spiral downward force is generated on the water flow in the cylinder 1, forming a vortex state, prolonging the contact time between water and air, and continuously fusing oxygen and water flow during movement, thereby further increasing the dissolved oxygen content in the water.

[0028] In order to drive the shaft tube 3 to rotate, the structure of the driving component is refined below. The driving component includes a base frame fixedly connected to the lower surface of the cylinder 1, and the bottom surface inside the base frame is fixedly connected to a waterproof motor 4. The output shaft of the waterproof motor 4 passes through the lower side wall of the cylinder 1 and is coaxially fixedly connected to the shaft tube 3. After the waterproof motor 4 is started, its output shaft drives the shaft tube 3 to rotate.

[0029] In order to be able to pump air into the shaft tube 3 when the shaft tube 3 rotates, the structure of the air intake assembly is detailed below. The air intake assembly includes a sleeve 33 rotatably connected to the upper end of the shaft tube 3. One side of the sleeve 33 is fixedly connected to an air intake pipe 34. One end of the air intake pipe 34 passes through the side wall of the cylinder body 1 and extends out. The end of the air intake pipe 34 away from the cylinder body 1 is connected to an external air pump. After the air pump is started, air is pumped into the interior of the shaft tube 3 through the air intake pipe 34 and the sleeve 33. When the shaft tube 3 rotates, the shaft tube 3 rotates relative to the sleeve 33, and the sleeve 33 remains stationary, which does not affect the pumping work.

[0030] When the air discharged from the hollow plate 31 through the through hole 32 mixes with water, bubbles are generated in the water. The bubbles confine the air inside, so that the oxygen in the air in the bubbles cannot dissolve in the water. In order to burst these bubbles and allow more oxygen to dissolve in the water, a reciprocating mechanism 5 is provided on the lower side of the upper support frame 2. A plurality of bubble puncturing nails 6 are provided in a ring array between the reciprocating mechanism 5 and the spiral blades 35. When the shaft tube 3 drives the hollow plate 31 to rotate, the reciprocating mechanism 5 drives the bubble puncturing nails 6 to move back and forth vertically. Through the vertical reciprocating movement of the plurality of bubble puncturing nails 6, the bubbles spirally transported by the spiral blades 35 are continuously burst, thereby increasing the dissolved oxygen content in the water in the cylinder 1.

[0031] In order to drive the piercing nail 6 to move back and forth vertically when the shaft tube 3 drives the hollow plate 31, the structure of the reciprocating mechanism 5 is detailed below, referring to Figure 3 and Figure 4The reciprocating mechanism 5 includes several concentrically arranged positioning rings 51, and the upper ends of several puncture nails 6 are respectively fixedly connected to the lower surfaces of several positioning rings 51. The top annular array of the positioning ring 51 is fixedly connected to several vertical rods 52. The side wall annular array of the support frame 2 is provided with several drain holes 21. The upper ends of the vertical rods 52 pass through the drain holes 21 and extend to the top of the support frame 2 above. The upper ends of the vertical rods 52 are fixedly connected with ball heads 53. The drain holes 21 limit the vertical rods 52 to move vertically only along the axial direction. A spring 54 is provided on the outer movable sleeve of the vertical rod 52. The two ends of the spring 54 are respectively fixedly connected to the support frame 2 and the positioning ring 51. The ball head 53 is higher than the lower surface of the hollow plate 31 above, and the shaft tube 3 drives the hollow plate 31 to rotate until it is in contact with the ball head 53. After the contact position is reached, the hollow plate 31 presses the ball head 53 downward, pushing the ball head 53 and the vertical rod 52 to move vertically downward. The vertical rod 52 moves downward to press the positioning ring 51, so that the positioning ring 51 drives the bubble nail 6 to move downward synchronously. The distance between the positioning ring 51 and the support frame 2 increases, and the spring 54 elastically stretches. When the top of the ball head 53 contacts the lower surface of the hollow plate 31, the positioning ring 51 and the bubble nail 6 stop moving downward. When the hollow plate 31 rotates to a position where it does not contact the ball head 53, the spring 54 rebounds and drives the positioning ring 51 and the bubble nail 6 to move upward, thereby realizing the vertical reciprocating movement of the bubble nail 6. During the vertical reciprocating movement, the tip of the bubble nail 6 can puncture more bubbles, allowing more oxygen to dissolve in the water, thereby increasing the dissolved oxygen content in the water in the cylinder 1.
