Detailed Description

The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings of the present invention, and obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

In this specification, for convenience and simplicity of description, the aeration disc is considered to be in the horizontal direction at the time when the aeration disc is in the horizontal direction based on the orientation in which the surface of the boss provided with the through groove is in the horizontal direction.

Similarly, for the convenience and simplicity of description, the aeration trays are integrally plate-shaped, and the orientation is taken as the horizontal position thereof with respect to the plane having the largest area, and the plurality of aeration trays can be stacked one on another with the largest area.

As shown in fig. 1 and 2, the aeration disc of the present invention is hollow plate-shaped, and when the aeration disc is in the horizontal direction, the hollow structure thereof penetrates through the aeration disc in the vertical direction for the connecting column to pass through; the positioning hole is arranged on the connecting plate and is positioned at the inner edge part of the connecting plate, and the outer edge part of the connecting plate is provided with a boss higher than the middle part of the connecting plate, so that the whole section is concave when the aeration disc is positioned in the horizontal direction, namely the configuration that the outer edge part is high and the middle part is low; the boss distributes along aeration dish body outer peripheral edges, and the logical groove that the boss surface set up is located the surperficial inside and outside of boss, and the boss is towards one side at aeration dish center and towards the one side in the aeration dish outside promptly, and the tip is link up, open-ended logical groove for it is link up at the boss surface to lead to the groove. The connecting plate outer fringe part both sides of aeration dish body all set up the boss, perhaps also can the unilateral set up the boss, and the boss sets up logical groove, and the back of body another side is smooth surface.

When the lug boss of the through groove arranged on the aeration disc is in the horizontal direction, the outline of the through groove can be in a V shape, a rectangle, an arc (including a semicircle) or any other available form when being observed along the vertical direction vertical to the horizontal direction; the through grooves are distributed on the aeration disc in various ways, such as being distributed along the radial direction, namely diverging outwards from the center; however, the term "radial" herein does not necessarily mean that the aeration disc is of a particular shape, such as circular; spiral distribution, etc. In addition, the through grooves can be continuously and uniformly distributed on the surface of the boss of the aeration disc, and can also be distributed discretely, for example, a distance exists between one group of through grooves and the other group of through grooves, and the distance is different from the interval between the through grooves in the group. The length that leads to the groove can be set for according to actual need and processing technology, if for radial distribution, then its length is the radial length of boss, however, as long as aeration dish boss surface is equipped with all has open-ended to lead to the groove at the inside and outside tip of boss for it is link up on the boss surface to lead to the groove, then can realize utility model purpose, and belong to utility model's scope, and its concrete size is not limited. For example, the width of the through grooves formed on the convex surface of the aeration disc is preferably 0.07mm to less than 0.1mm (i.e., 0.07-0.1mm, but not 0.1 mm; if one through groove has a non-uniform width over the entire length of the through groove, the maximum value and the minimum value thereof vary within a range of 0.07mm to less than 0.1 mm), and the depth of the through groove is 0.1-1.2mm (if one through groove has a non-uniform depth over the entire length of the through groove, the maximum value and the minimum value thereof vary within a range of 0.1-1.2 mm). Unexpectedly, the inventors have experimentally verified that, as long as the width of the through slots is between 0.07mm and less than 0.1mm, a beneficial effect can be achieved regardless of the height of the through slots: when the diameter is less than 0.07mm, the aeration resistance is large; if the diameter is higher than 0.1mm, the gas is discharged into large bubbles, and the gas utilization rate is low. The interval between the through grooves is 0.05-2 mm. For example, the height of the bosses (from the mid-plane of the aeration disc) is 0.1-2.0mm, and the width of the bosses (in terms of the direction of the bosses along a line extending outward from the center of the aeration disc) is 0.5-30 mm. Preferably, the height of the bosses is greater than the depth of the through slots, which helps to form a chamber for storing gas in the space surrounded by the bosses, facilitating stable operation of the aeration process.

The hollow structure outward flange of aeration dish can be circular, the rectangle, oval etc., preferably circular, its size is preferably slightly more than the external diameter size of spliced pole, the fixed column that the spliced pole set up in axial direction combines with the locating hole that aeration dish connecting plate inner edge position set up, the aeration dish of being convenient for is installed and the loose joint on the spliced pole, the shape of hollow structure outward flange is preferably unanimous with the outside profile of spliced pole, but this is just in processing and convenient assembling's consideration, if the shape of hollow structure outward flange is inconsistent with the outside profile of spliced pole, then during the connection, must form the space between aeration dish and spliced pole, can reduce the result of use of aerator, then probably adopt gasket etc., form the space between sealed aeration dish and the spliced pole. The size and the thickness of the aeration disc are not limited and can be determined according to actual needs. For example, the aeration disk may have a diameter (in terms of the diameter of an inscribed circle, when non-circular) of 5 to 250mm and a thickness of, for example, 1 to 5 mm.

Set up the maintenance device on the aeration dish, set up the constant head tank at the positive connecting plate of body promptly, for constant head tank central point, the body back sets up the reference column. Like this in two adjacent aeration dish, the constant head tank that the connecting plate of one of them aeration dish body set up, with another aeration dish corresponding the back set up with the reference column that this constant head tank corresponds, the reference column can insert in the constant head tank, from this, can effectively prevent the drunkenness displacement between the aeration dish at aeration in-process to work reliably.

The aeration disc of the utility model is made of metal (aluminum, iron, etc.), plastic material (such as polyethylene, polypropylene, polymethyl methacrylate, polyformaldehyde, polycarbonate, etc.) or hard rubber.

The aeration disc of the present invention can be manufactured by various known manufacturing methods, for example, injection molding, casting, cutting, turning, etc.

The dimensions of the aeration disc of the embodiment are given below, but of course, the dimensions of the various components of the present invention may be adjusted according to specific production requirements.
