TECHNICAL FIELD

[0001] The application belongs to the field of aeration equipment, and particularly relates to a low-energy-consumption water treatment aeration equipment. BACKGROUND

[0002] Most of the existing aeration equipment is simply combined by a gas supply device and a nozzle, and manual adjustment is required when the aeration amount is controlled. Such aeration equipment is prone to blockage of the air outlet, which leads to difficult air outlet, increased energy consumption and reduced aeration effect.

[0003] Currently, there is also a membrane type aeration equipment. Compared with the traditional aeration equipment, the aeration hole diameter is smaller, and the steam pocket and water fusion efficiency are higher. However, such a membrane type aeration equipment has the defects that dirt and impurities are easily attached to the surface of the membrane, and the membrane is easily damaged when contacted by sharp impurities in the water body.

[0004] The application aims to provide a low-energy-consumption water treatment aeration equipment, which can greatly reduce the interference of dirt and impurities on the aeration equipment and the aeration process, improve the aeration efficiency, and reduce the energy consumption, compared with the above-mentioned aeration equipment.

DETAILED DESCRIPTION

[0023] In order to enable the personnel in the technical field to better understand the present application scheme, the present application is further described in detail below in combination with the drawings and specific embodiments.

[0024] It should be noted here that the up and down orientation words involved in the present application are relative to the drawings. Figures 1 to 7The middle parts in the figure and the positions of the parts relative to each other are defined only for the purpose of expressing the technical solution clearly and conveniently. It should be understood that the orientation words used herein should not limit the scope of the application claimed.

[0025] A low-energy water treatment aeration device, comprising an aeration pipe 1, the aeration pipe 1 is connected with a bottom plate 10 through a connecting sleeve 7, the bottom plate 10 is provided with a fixing frame 11, the fixing frame 11 is fixedly connected with an aeration membrane 13 inside, the bottom plate 10 is provided with a sliding rail 20, the sliding rail 20 is connected with a rotating ring 17 through a ball bearing 18 (the bottom plate 10 and the rotating ring 17 are vertically limited, which will not be described here), the rotating ring 17 is fixedly provided with an air outlet cover 3. The sliding rail 20 can also be rotatably connected with the rotating ring 17 through a rotating bearing or other connection modes.

[0026] As a further embodiment, the air outlet cover 3 is provided with a plurality of grid-shaped air outlet grooves 4.

[0027] As a further embodiment, the air outlet cover 3 is provided with a top plate 5, the top plate 5 is provided with a through hole in the middle, the through hole is provided with a column 8, the upper end of the column 8 is provided with an upper stop block 6, the lower end of the column 8 is provided with a lower stop block 15, the lower stop block 15 is connected with a stop ring 21 through a spring 9, the stop ring 21 is arranged around the column 8, and the stop ring 21 is tightly attached to the bottom of the top plate 5. The stop ring 21 abuts against the bottom of the top plate 5, and when the air outlet cover 3 rotates, it rotates relative to the stop ring 21, and the spring 9 does not interfere with the rotation.

[0028] As a further embodiment, two sliding balls 14 are arranged on the wall surface of the through hole, and a threaded sliding groove 22 is arranged on the outer circumferential surface of the column 8, and the sliding ball 14 is slidingly arranged in the sliding groove 22.

[0029] As a further embodiment, the aeration membrane 13 is fixedly provided with a fixed membrane piece 12 in the middle.

[0030] As a further embodiment, the bottom of the lower stop block 15 is provided with a clamping groove 16, and the upper end of the fixed membrane piece 12 is fixedly provided with a clamping strip 19 matched with the clamping groove 16. Due to the existence of the spring 9, the clamping strip 19 and the clamping groove 16 will also maintain contact during the process of gradually flattening the aeration membrane 13 under reduced pressure until the initial contact is restored, and the situation that the clamping strip 19 is lowered in advance to cause the subsequent clamping groove 16 and the clamping strip 19 to be misaligned will not occur.

[0031] In this embodiment, when normal aeration is performed, gas is introduced into the lower part of the aeration membrane 13 through the aeration pipe 1, is sprayed out through the aeration holes of the aeration membrane 13, and then is sprayed out through the air outlet grooves 4 of the air outlet cover 3 to mix with the water body to realize aeration. During the aeration process, the aeration membrane 13 will be inflated, and the fixed membrane piece 12 will not be in contact with the lower stop block 15 in the normal aeration state.

[0032] When the aeration holes are blocked, the gas discharge efficiency of the aeration membrane 13 is reduced when aeration is carried out, the internal pressure of the aeration membrane 13 is increased, the aeration membrane 13 is inflated, and when the inflation height reaches the contact between the fixed membrane 12 and the lower stop block 15, the clamping strip 19 is clamped into the clamping groove 16, and as the aeration membrane 13 continues to inflate, the membrane surface of the aeration membrane 13 is close to the inner wall surface of the air outlet cover 3, and at the same time, under the pushing of the aeration membrane 13, the column 8 is pushed upward, the sliding ball 14 is moved through the sliding groove 22, thereby driving the air outlet cover 3 to rotate, and the edge of the air outlet groove 4 of the air outlet cover 3 contacts the impurities on the aeration membrane 13, thereby scraping off the impurities, and at the same time, due to the resistance of rotation, the aeration membrane 13 itself will also appear slight torsion, which is combined with the aeration vibration during aeration to quickly twist and shake off the impurities, and then combined with the wall surface of the air outlet groove 4 to scrape off.

[0033] It should be noted that this process is a gradual process, and when the impurities attached to the surface of the aeration membrane 13 are not stubborn, they may be shaken off and discharged by the cooperation of the aeration membrane inflation process and the air outlet. During the gradual inflation of the aeration membrane 13, the edge of the air outlet groove 4 will first contact the impurities attached to the aeration membrane, and if the scraping effect is achieved, the aeration holes are reopened, the internal pressure of the aeration membrane 13 is reduced, and the aeration membrane quickly returns to the normal aeration state, so the scraping action will not appear violent extrusion of the aeration membrane 13, and will not aggravate the damage to the aeration membrane 13.

[0034] By unblocking the aeration holes, the aeration state is quickly restored to avoid the situation that the internal pressure is increased due to the inability to normally aerate, thereby aggravating the consumption of aeration energy, thereby achieving the effect of solving energy and improving aeration efficiency.

[0035] The above is only an embodiment of the present application, and does not limit the patent protection range of the present application, and any equivalent structure or equivalent flow transformation using the content of the specification and drawings, or direct or indirect application in other related technical fields, are also included in the patent protection range of the present application.
