Technical Field

[0001] The utility model relates to the technical field of sewage treatment, and particularly relates to a swirl aerator. Background Art

[0002] A swirl aerator is an efficient air-water mixing and aeration device. Through a swirl structure, air and water are fully mixed to form fine bubbles, enhancing the oxygen transfer efficiency. It also has a stirring function to promote water circulation. It is suitable for improving dissolved oxygen and the activity of activated sludge in sewage treatment, and has advantages such as low energy consumption, high oxygen utilization rate, and anti-blockage.

[0003] A Chinese patent discloses a swirl aerator (Publication No.: CN211283852U). Due to the setting of a limiting mechanism, the pulling column can be pulled, and the limiting column can be pulled into the limiting frame. At the same time, the reset spring contracts. Then, the swirl aerator main body is placed on a pre-fixed installation groove. At the same time, the installation block on the swirl aerator main body is located inside the installation groove. Then, the pulling column is released, and its reset spring pushes the limiting column into the limiting hole on the installation block, fixing the installation block in the installation groove, that is, fixing the swirl aerator main body on the installation groove to complete the installation, thereby realizing the advantage of being easy to install.

[0004] The above device also has the following defects: When the swirl aerator needs to be fixed, the operator not only needs to hold and position the installation groove in the above device, pull up the pulling column, but also align the installation groove and connect it to the outside of the installation block on the side of the swirl aerator, which is rather troublesome. Therefore, a swirl aerator is proposed to solve the above problems. Summary of the Utility Model

Detailed Embodiments

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the attached drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the protection scope of the present utility model.

[0026] Such as Figures 1-5As shown in the figure, a swirl aerator includes a swirl aerator main body 1. A fixing mechanism 2 is provided on one side of the swirl aerator main body 1. The fixing mechanism 2 includes a mounting sleeve 201. A flange end plate 202 is fixedly connected to the outer wall on one side of the mounting sleeve 201. Symmetrically fixed to the middle of the outer wall of the mounting sleeve 201 are limiting rails 203. One side of each limiting rail 203 is fixedly connected to the surface of the flange end plate 202; Slidably connected to the inner side of each limiting rail 203 is a limiting slide plate 204. Fixedly connected to the side of each limiting slide plate 204 away from the mounting sleeve 201 is a pushing block 205. A magnetic attraction block 210 is inlaid and fixed on the side of the pushing block 205. The surface of the magnetic attraction block 210 is magnetically connected to the inner side of the limiting rail 203; Among them, symmetrically slidably and penetratingly connected to the middle of the mounting sleeve 201 are clamping blocks 206. An extrusion hole 207 is opened at one end of the inner wall of the clamping block 206. The inside of the extrusion hole 207 is penetrated by the limiting slide plate 204, and the inside of the extrusion hole 207 abuts against and is slidably connected to the pushing block 205, as Figure 2 、 Figure 5 shown in the figure. The limiting rail 203 is made of iron. When the pushing block 205 abuts against the inner side of the limiting rail 203, it is adsorbed to the inner side of the limiting rail 203 through the magnetic attraction block 210 for positioning. An arc for transition is provided on the side of the inner wall of the extrusion hole 207. This arc abuts against the slope surface of the pushing block 205, facilitating the pushing of the inside of the extrusion hole 207 when the pushing block 205 moves;

[0027] A slope is provided at one end of the clamping block 206 away from the extrusion hole 207. A slider 208 is fixedly connected to the middle of the outer wall of the clamping block 206. A second spring 209 is fixedly connected to one side of the slider 208. The outer wall of the slider 208 is slidably connected to the inner wall of the mounting sleeve 201. The side of the second spring 209 is also fixedly connected to the inner wall of the mounting sleeve 201, as Figures 4-5 shown in the figure. A linear chute is opened on the inner wall of the mounting sleeve 201, and the movement direction of the clamping block 206 is limited by accommodating the slider 208. There is friction between the inner wall of the linear chute and the slider 208, thus preventing the second spring 209 and the slider 208 from shaking due to external vibration and ensuring the stability of the clamping block 206;

[0028] The swirl aerator main body 1 includes a housing 101. A mounting block 110 is fixedly installed in the middle of the outer wall of the housing 101. Slopes are symmetrically provided on the side of the mounting block 110 away from the housing 101. Triangular clamping grooves 111 are symmetrically opened in the middle of the outer wall of the mounting block 110. The mounting block 110 is inserted into the inside of the mounting sleeve 201, and the inside of the triangular clamping groove 111 abuts against the clamping block 206.

[0029] In the middle of the side of the housing 101 away from the mounting block 110, an air inlet pipe 102 is fixedly and penetratingly connected. Limiting holes 103 are symmetrically opened in the middle of the air inlet pipe 102. A ball 104 is installed in each limiting hole 103. One end of the ball 104 extends into the inside of the air inlet pipe 102, asFigure 3 As shown, the movement of the ball 104 in the limit hole 103 is restricted, and the ball 104 cannot escape from the limit hole 103;

[0030] A push cylinder 105 is also slidably sleeved on the outer wall of the intake pipe 102. The middle part of the push cylinder 105 is aligned with the limit hole 103 and abuts against the ball 104. One side of the inner wall of the push cylinder 105 is fixedly connected with a first spring 106, and the other side of the first spring 106 is fixedly connected with the outer wall of the intake pipe 102. A gas transmission pipe 107 is inserted into the inner wall of the intake pipe 102. Arc-shaped card slots 108 are symmetrically arranged on the outer wall of the end of the gas transmission pipe 107, and the inside of the arc-shaped card slots 108 abuts against the ball 104. A sealing ring 109 is also fixedly connected to the side of the gas transmission pipe 107, and the surface of the sealing ring 109 abuts against the gas transmission pipe 107. As Figure 3 shown, through the sliding friction between the inner side of the push cylinder 105 and the outer side of the intake pipe 102, the shaking of the first spring 106 caused by vibration is avoided, and thus the position of the push cylinder 105 relative to the intake pipe 102 is kept fixed.

[0031] The working principle of the present utility model:

[0032] When the swirl aerator main body 1 is fixed, it needs to be assembled with the fixing mechanism 2 and fixed on the support plane in cooperation with the flange end plate 202 in the fixing mechanism 2. The mounting block 110 is directly inserted into the inside of the mounting sleeve 201. The slope at the end of the mounting block 110 presses the side of the clamping block 206 and moves from the clamping block 206 to the outside of the mounting sleeve 201. The slider 208 moves along the linear chute arranged inside the mounting sleeve 201, and the second spring 209 is compressed. After the mounting block 110 is inserted in place in the mounting sleeve 201, the clamping block 206 is exactly aligned with the triangular card slot 111. Thus, the second spring 209 releases its elastic potential energy, drives the clamping block 206 to insert into the inside of the triangular card slot 111 by pushing the slider 208, and completes the locking; when it is necessary to separate the mounting block 110 from the mounting sleeve 201, the push block 205 is pushed along the inside of the limit rail 203, so that the push block 205 presses and pushes the side of the inner wall of the extrusion hole 207, so that the clamping block 206 receives a force in the direction away from the mounting block 110, and thus the clamping block 206 releases the contact with the inside of the triangular card slot 111;

[0033] Secondly, when connecting the intake pipe 102 and the gas transmission pipe 107, the push cylinder 105 is pushed towards the direction close to the housing 101, and the end of the gas transmission pipe 107 can be directly aligned and inserted into the inside of the intake pipe 102. After the push cylinder 105 is released, the first spring 106 drives the push cylinder 105 to reset, and the inner wall of the push cylinder 105 presses the two balls 104 against the inside of the arc-shaped card slots 108 respectively, thus completing the locking of the connection between the intake pipe 102 and the gas transmission pipe 107.

[0034] The above has described in detail an embodiment of the present utility model, but the above content is only a preferred embodiment of the present utility model and cannot be considered as limiting the scope of implementation of the present utility model. All equivalent changes and improvements made according to the scope of application of the present utility model shall still fall within the scope covered by the patent of the present utility model.
