Description

Technical Field

[0001] The utility model belongs to the technical field of water treatment equipment, and in particular relates to an aeration device. Background Art

[0002] At present, in the salt and quality separation project of water treatment, the high-concentration brine regulating water tank has the following problems in operation: Since the high-concentration brine contains a large amount of suspended solids, the regulating water tank lacks an agitator, resulting in a lot of silt at the bottom of the pool, which not only easily blocks the pump port of the brine lift pump and affects the operation of the system, but also increases the annual dredging task and reduces the volume of the regulating water tank. In addition, the accumulation of organic matter in the regulating water tank will also lead to increased organic fermentation, which will have a great impact on the overall operation of the subsequent system.

[0003] The existing solution is to install an aeration device or a mechanical stirring device at the bottom of the regulating pool to oxygenate and stir the regulating pool. However, the mechanical stirring device is often complicated to maintain and the maintenance frequency is high. The existing aerator is easily blocked in high-salt and high-suspended-matter water, and the stirring effect is poor. Utility Model Content

[0004] The utility model aims to provide an aeration device to solve the technical problems existing in the prior art that the aerator is easily blocked and the stirring effect is poor.

[0005] In order to achieve the above purpose, the specific technical solution of the utility model is as follows:

[0006] An aeration device comprises an aeration shell, a plurality of aeration holes evenly arranged on the bottom surface of the aeration shell, and a plugging mechanism arranged in the aeration shell, wherein air pipe connecting holes are provided on both sides of the aeration shell and are connected to an external air supply pipe, wherein the plugging mechanism is a telescopic mechanism, wherein a fixed end of the plugging mechanism is arranged in the aeration shell, and after the telescopic end extends from the aeration shell through the aeration holes to the outside of the aeration shell, it is detachably connected to a guide cover, and the guide cover is a cover body having a diameter larger than the aeration holes.

[0007] The telescopic mechanism includes an extension rod, a connecting rod and an automatic rebound portion. The number of the extension rods corresponds to the number of aeration holes. One end of the extension rod extends out of the aeration hole and is detachably connected to the guide cover and is gap-matched with the aeration hole. The connecting rod is fixedly connected to one end of each row or column of extension rods located in the aeration shell and is connected to the interior of the aeration shell through the automatic rebound portion.

[0008] The automatic rebound part includes a guide pile and a compression spring. The guide pile is rod-shaped and vertically fixed on the bottom surface of the aeration shell. The compression spring is sleeved on the guide pile. The connecting rod is connected to the upper end of the compression spring.

[0009] The automatic rebound part also includes connecting rods, and every two connecting rods form a group, and two or more connecting rods are evenly arranged between the two connecting rods in each group.

[0010] The height of the guide pile is greater than the height of the jacking rod.

[0011] The aeration shell comprises a main shell and a top cover which closes the inner cavity of the main shell and is detachably fixedly connected with the main shell.

[0012] The beneficial effects of the utility model are as follows: the utility model provides an aeration device, and by arranging a blocking mechanism in the main shell of the device, and arranging it in a spring-compressed form, the device can automatically close the aeration holes on the aeration shell when there is no airflow flowing in, so that the device is automatically in a closed state to prevent suspended matter from entering the aeration holes and causing blockage. When an airflow of a certain pressure is introduced, the diversion cover automatically moves away from the aeration shell under the pressure of the airflow, and the spring is compressed by the pressure of the top extension rod, the connecting rod and the connecting rod, and the aeration hole opens to spray airflow into the regulating tank. At the same time, since the diversion cover is arranged at the aeration hole, the sprayed airflow is changed from the original direct spray to spraying to all sides along the diversion cover, thereby increasing the spray area of ​​the airflow, so that a larger area of ​​high-concentration brine can be stirred, so that the precipitation of suspended matter can be better avoided, thereby effectively reducing the accumulation of sludge in the regulating water tank.

[0020] In order to better understand the purpose, structure and function of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings.

[0021] like Figures 1 to 6 As shown, the utility model provides an aeration device, which includes an aeration shell 1, a plurality of aeration holes 103 evenly arranged on the bottom surface of the aeration shell 1, and a blocking mechanism arranged in the aeration shell 1. Air pipe connecting holes 4 are opened on both sides of the aeration shell 1, which are connected with the external air supply pipe and are used to allow external air flow to flow into the aeration shell 1. The blocking mechanism is a telescopic mechanism, and the fixed end of the blocking mechanism is arranged in the aeration shell 1. After the telescopic end extends from the aeration shell 1 through the aeration holes 103 to the outside of the aeration shell 1, it is detachably connected to the guide cover 5 for easy installation. The guide cover 5 is a cover body with a diameter larger than the aeration holes 103. The setting of the blocking mechanism can drive the guide cover 5 to press the outer surface of the aeration shell 1 when there is no air flow flowing in, thereby automatically closing the aeration holes 103, preventing the highly concentrated brine in the regulating tank from entering the aeration device from the aeration holes 103, thereby preventing the aeration holes 103 from being blocked and scaling in the aeration device.

[0022] Further, such as Figures 2 to 4 As shown, the telescopic mechanism includes a top extension rod 6, a connecting rod 7 and an automatic rebound portion. The top extension rod 6 corresponds to the number of aeration holes 103 and is in clearance with the aeration holes 103. Figure 6 As shown, one end of the extension rod 6 extends out of the aeration hole 103 and is detachably connected to the guide cover 5, and the connecting rod 7 is fixedly connected to one end of each row or column of the extension rods 6 located in the aeration shell 1, and is connected to the interior of the aeration shell 1 through the automatic rebound part. Among them, the automatic rebound part in this embodiment includes a guide pile 8 and a compression spring 9, the guide pile 8 is rod-shaped and vertically fixed on the bottom surface of the aeration shell 1, the compression spring 9 is sleeved on the guide pile 8, and the connecting rod 7 is connected to the upper end of the compression spring 9 through the connecting rod 10, as shown in FIG. Figure 2 Figure 4 As shown, every two connecting rods 10 form a group, and two or more connecting rods 10 are evenly arranged between the two connecting rods 10 in each group.

[0023] Furthermore, in order to provide a limit for the compression spring 9 and prevent the spring from escaping from the guide pile 8, the height of the guide pile 8 is greater than the height of the extension rod 6. In this embodiment, a detachable limit block is also provided on the top of the guide pile 8.

[0024] Furthermore, in order to facilitate the disassembly and assembly of the sealing mechanism, the aeration shell 1 in this embodiment includes a main shell 101 and a top cover 102, wherein the top cover 102 is detachably sealedly connected to the main shell 101, and is used to seal the inner cavity of the main shell 101 so that the airflow only passes through the aeration holes 103.
