Description

Technical Field

[0001] The utility model relates to the technical field of aerators, in particular to an aerator. Background Art

[0002] The new vortex aerator (aeration head) injects "micro bubbles" directly into untreated sewage through the air-dispersing impeller. Under the joint action of coagulants and flocculants, the suspended matter undergoes physical and chemical flocculation, thereby forming large suspended matter flocs. Under the buoyancy of the bubble group, the "flocs" float to the liquid surface to form scum, which is separated from the water by a scraper.

[0003] When the aerator is used in a pool, since the pool contains impurities such as leaves, water plants, flexible plastic bags and dead fish remains, the aerator will absorb the impurities into the mixing disk together with the water, causing the water outlet of the mixing disk to be blocked, affecting the use of the aerator. In this case, a motor-driven cutter is generally provided at the water inlet of the aerator, and the cutter is used to rotate and cut off the impurities entering from the aerator inlet, so that the volume of the impurities is reduced and dispersed, thereby achieving the purpose of preventing blockage. For example, an aerator disclosed in a Chinese patent with publication number: CN220012356U, however, when the cutter is cutting, some flexible impurities cannot be cut off and are entangled on the rotating shaft of the rotating blade. Since the rotating shaft of the blade is coaxial with the aerator, the blade and the aerator cannot be used. Therefore, an aerator is designed to solve the above-mentioned problems.

[0006] The driving assembly drives the cutting assembly to approach the filtering assembly, so that the cutting assembly moves upward and contacts with the surface of the filtering assembly to form an extrusion force, so as to cut off the flexible impurities intercepted on the surface of the filtering assembly.

[0012] Compared with the prior art, the utility model has the following beneficial effects: by providing a filter plate with a blade surface at the water inlet and a conical block and a mounting plate at the lower end of the filter plate, the water in the pool is filtered before entering the aerator; the mounting plate is used in conjunction with the blade surface of the filter plate to cut off flexible impurities, so that they form small impurities that do not block the aerator, thereby allowing the aerator to be used normally and avoiding large flexible impurities from directly entering the aerator body; and the method of rotary cutting with a cutter is not adopted, which also avoids flexible impurities from being entangled on the cutter and causing extreme damage.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Example

[0020] See also Figure 1-3 The present embodiment provides an aerator, including an aerator body 1, a filter assembly, a cutting assembly and a driving assembly, wherein the aerator body 1 is a centrifugal aerator, which is a well-known device in the art, and therefore will not be described in detail. The water inlet at the lower end of the aerator body 1 is fixedly connected to a mounting frame 2, the mounting frame 2 is connected to the water inlet of the aerator body 1, a fixing groove is provided at the bottom of the mounting frame 2, and a filter plate 3 is fixedly connected in the fixing groove. When in use, the aerator body 1 is started, so that the aerator body 1 sucks water from the pool from the water inlet. During the sucking process, larger impurities and soft impurities in the water are blocked by the filter plate 3 and cannot enter, thereby preventing the aerator body 1 from being blocked inside.

[0021] The filter plate 3 is formed by welding a plurality of No. 1 cutters 31 and No. 2 cutters 32 in a staggered manner. The mesh formed by the cross-section of the No. 1 cutters 31 and No. 2 cutters 32 is a flow slot 33. The flow slot 33 allows smaller impurities and water to enter the aerator body 1 for circulation. Figure 4 As shown, the blade of the cutter faces the water pool, and the filter plate 3 is provided to prevent the entry of larger impurities and soft impurities. The lower end of the aerator body 1 is fixedly connected to the electric push rod 4 on both sides near the water inlet, the output end of the electric push rod 4 is fixedly connected to the connecting plate 41, the connecting plate 41 is fixedly connected to the support plate 5 near the water inlet of the aerator body 1, the upper end of the support plate 5 is fixedly connected to two elastic sheets 6, and the upper end of the elastic sheet 6 is fixedly connected to the mounting plate 7, as shown in FIG. Figure 2 shown.

[0022] When the mounting plate 7 and the filter plate 3 are used to squeeze and cut off the trapped flexible impurities, it is found that some of the flexible impurities may not be completely cut off, and the uncut flexible impurities may cover the flow groove 33, resulting in blockage of the flow groove 33. Therefore, a plurality of conical blocks 8 are fixedly connected to the upper end of the mounting plate 7. The conical blocks 8 are as follows: Figure 2 As shown, the tip of the conical block 8 faces the filter plate 3, and the conical block 8 is aligned with the flow slot 33, so that the conical block 8 can be inserted into the flow slot 33. The conical block 8 is driven into the flow slot 33 by the mounting plate 7, which can pierce the flexible impurities and prevent the flow slot 33 from being blocked, thereby ensuring that water enters the aerator body 1 normally and the aerator body 1 can operate normally.

[0023] It should be noted that a corresponding sleeve and sleeve rod may be installed between the mounting plate 7 and the support plate 5 to form a telescopic rod, which is used to limit the movement of the upper mounting plate 7 and prevent the mounting plate 7 from being excessively deflected by the water flow.

[0024] When in use, the aerator body 1 is started, so that the aerator body 1 sends the water in the pool from the water inlet into the mixing chamber in the aerator body 1 to mix with the drawn air and spray it out. In the process of water entering the pool, the impurities in the pool are filtered by the filter plate 3, so that large impurities and flexible impurities are blocked and attached to the filter plate 3. At this time, the electric push rod 4 is started, so that the electric push rod 4 drives the support plate 5 to rise, and the support plate 5 drives the mounting plate 7 to rise, so that the conical block 8 at the upper end of the mounting plate 7 rises, and the mounting plate 7 contacts the lower end of the filter plate 3 after rising, and the cutter and the mounting plate 7 squeeze the large impurities and flexible materials, and the blade surface of the filter plate 3 applies shear force to cut off the impurities and flexible materials, so that the flexible materials and impurities enter the aerator body 1 for circulation, and the aerator body 1 is not damaged.

[0025] Even if some flexible impurities cannot be cut off, the conical block 8 that rises together with the mounting plate 7 will be inserted into the flow slot 33 to dredge the flow slot 33, preventing the flexible impurities from blocking the flow slot 33 and affecting the entry of water. At the same time, the conical block 8 is inserted into the flow slot 33, so that the conical block 8 pushes the impurities stuck in the flow slot 33 to prevent the filter plate 3 from being continuously blocked and affecting the water entering the aerator body 1. The overall cutting process time does not exceed 5 seconds. Repeat this process to continuously squeeze and crush impurities and cut flexible materials.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
