Description

Technical Field

[0001] The utility model belongs to the technical field of aerators, in particular to a novel aerator. Background Art

[0002] During the sewage treatment process, certain methods and equipment are used to force air into the sewage, so that the sewage in the pool comes into contact with the air and is oxygenated, and the liquid is stirred to accelerate the transfer of oxygen in the air to the liquid, preventing suspended objects in the pool from sinking, and strengthening the contact between organic matter in the pool and microorganisms and dissolved oxygen, thereby oxidizing and decomposing the organic matter in the sewage. This process of forcing oxygen into the sewage is called aeration.

[0003] In the existing sewage treatment, sewage is aerated by an aerator. In order to facilitate the maintenance of the aerator in the prior art, a lifting aerator is used, which is mainly to hang the aerator in the sewage pool. Then, when the aerator needs to be maintained, it is only necessary to disassemble the aerator air inlet pipe and the air supply pipe at the corresponding position, and then the personnel can lift the aerator to maintain the aerator. In the actual use of the above-mentioned existing aerators, the applicant found that the above-mentioned liftable and maintainable aerators are generally hung on the air supply pipe, and in order to facilitate lifting and maintenance, the aerator is small in size, so a large number of aerators are hung on one air supply pipe. Due to the large number of aerators, they need to be lifted one by one for maintenance in the later stage, and they also need to be disassembled and assembled back and forth, which is troublesome to operate and the maintenance efficiency is very low. In order to solve the above-mentioned problems, a new type of aerator is provided. Utility Model Content

[0006] Vertical guide rods are fixedly installed on both sides of the mounting frame, and positioning tubes are fixedly connected on both sides of the horizontal plate. The vertical guide rods pass through the positioning tubes, and a through hole is opened on the positioning tube. A locking bolt is inserted into the through hole, and a locking nut is threadedly connected to the locking bolt. An insertion hole is clamped on the upper part of the vertical guide rod, and the locking bolt passes through the insertion hole.

[0007] In a preferred embodiment, two square holes are opened in the middle of the horizontal plate, and the iron chain passes through the square holes.

Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0020] The following will be combined Figure 1-Figure 4 A novel aerator according to an embodiment of the utility model is described in detail.

[0021] Example:

[0022] A novel aerator provided by the embodiment of the utility model, referring to Figures 1 to 4 As shown, it includes a horizontal plate 1, two support plates 2 are fixedly connected to the horizontal plate 1, a rotating shaft 3 is rotatably connected to the upper part of the support plate 2, reels 4 are fixedly connected to both sides of the rotating shaft 3, an iron chain 5 is wound around the reel 4, a mounting frame 6 is fixedly connected to the lower end of the iron chain 5, U-shaped tubes 7 are fixedly installed on both sides of the mounting frame 6, an air inlet pipe 8 is fixedly connected to the two U-shaped tubes 7, two slat aerators 9 are fixedly connected between the two U-shaped tubes 7, and the air inlet pipe 8, the U-shaped tube 7 and the slat aerator 9 of this structure constitute an aerator for a sewage pool;

[0023] The personnel can rotate the rotating shaft 3, and the rotating shaft 3 drives the reel 4 to rotate, so that the iron chain is wound around the reel 4, and then the mounting frame 6 is lifted, so that the U-shaped tube 7 and the slat aerator 9 are lifted upward to the upper part of the sewage, so as to facilitate the inspection and maintenance of the aerator composed of the U-shaped tube 7 and the slat aerator 9. The whole structure can lift and maintain large aerators. Compared with the existing small lifting aerator, the number of disassembly and lifting back and forth is less, the maintenance is more convenient, and the maintenance efficiency is improved.

[0024] refer to Figures 1 to 4 As shown, the lath aerator 9 includes a flat tube 22, and a microporous membrane 23 is arranged on the upper part of the flat tube 22. This structure uses the microporous membrane 23 on the flat tube 22 to disperse air into bubbles, and then diffuse it into the mixture, so that the sample in the bubbles is dissolved in the sewage.

[0025] refer to Figures 1 to 4 As shown, both ends of the rotating shaft 3 are provided with a socket 20, and a force rod 21 can be inserted into the socket 20. In this structure, a person can insert the force rod 21 into the socket 20, so that the person can use force to rotate the rotating shaft 3.

[0026] refer to Figures 1 to 4As shown, ratchets 10 are fixedly connected to both sides of the rotating shaft 3, and a pawl 11 is arranged on the upper part of the ratchet 10. The pawl 11 is rotatably mounted on the support plate 2. This structure is used when a person rotates the rotating shaft 3 to lift the aeration device. At this time, the ratchet 10 and the pawl 11 structure can lock the position of the rotating shaft 3, thereby locking the height of the aeration device, thereby facilitating the maintenance and cleaning of the aerator.

[0027] refer to Figures 1 to 4 As shown, the upper parts of the two support plates 2 are fixedly connected with the blocking columns 19. In this structure, after the slat aerator 9 is maintained, the personnel can first apply force to rotate the rotating shaft 3 so that the ratchet 11 can be flipped up and mounted on the blocking column 19, so that the ratchet 11 will not interfere with the bottom of the slat aerator 9. Then the personnel can slowly put the slat aerator 9 back into the sewage.

[0028] refer to Figures 1 to 4 As shown, vertical guide rods 12 are fixedly installed on both sides of the mounting frame 6, and positioning tubes 13 are fixedly connected on both sides of the horizontal plate 1. The vertical guide rods 12 penetrate the positioning tubes 13, and a through hole 14 is provided on the positioning tube 13. A locking bolt 15 is inserted into the through hole 14, and a locking nut 16 is threadedly connected to the locking bolt 15. A locking hole 17 is clamped on the upper part of the vertical guide rod 12, and the locking bolt 15 penetrates the locking hole 17. This structure uses the vertical guide rods 12 and the positioning tube 13 to position the mounting frame 6 when it moves up and down;

[0029] When the slat aerator 9 is in place, the personnel can pass the locking bolt 15 through the through hole 14 and the locking hole 17, and then screw the locking nut 16 into the locking bolt 15, thereby locking the vertical guide rod 12 and the positioning tube 13, thereby preventing the slat aerator 9 from shaking due to the sewage flow, ensuring the stable use of the slat aerator 9.

[0030] refer to Figures 1 to 4 As shown, two square holes 18 are opened in the middle of the cross plate 1, and the iron chain 5 passes through the square holes 18. The square holes 18 of this structure facilitate the iron chain 5 to pass through the cross plate 1 and connect with the mounting frame 6.

[0031] refer to Figures 1 to 4 As shown, a limit plate 24 is fixedly installed on the upper end of the vertical guide rod 12. This structure uses the limit plate 24 to limit the lowest downward position of the vertical guide rod 12.

[0032] The implementation principle of a novel aerator of the embodiment of the present application is as follows: when the slat aerator 9 needs to be maintained, the locking bolt 15 between the vertical guide rod 12 and the positioning tube 13 is first removed, and the personnel can insert the force rod 21 into the insertion hole 20, and then the personnel rotate the rotating shaft 3, and the rotating shaft 3 drives the reel 4 to rotate, so that the iron chain is wound around the reel 4, and then the mounting frame 6 is lifted, so that the U-shaped tube 7 and the slat aerator 9 are lifted upward to the upper part of the sewage, and at this time, the ratchet 10 pawl 11 structure can lock the position of the rotating shaft 3, thereby locking the height of the aeration device, so as to facilitate the inspection and maintenance of the aerator composed of the U-shaped tube 7 and the slat aerator 9;

[0033] When the inspection is completed, the rotating shaft 3 can be rotated with force so that the pawl 11 can be turned up and mounted on the blocking column 19, so that the pawl 11 will not interfere with the bottom of the slat aerator 9. Then the staff can slowly put the slat aerator 9 back into the sewage. When the bottom is in place, the staff will pass the locking bolt 15 through the through hole 14 and the locking hole 17, and then screw the locking nut 16 into the locking bolt 15, and then lock the position of the vertical guide rod 12 and the positioning tube 13, so as to avoid the sewage flow causing the slat aerator 9 to shake during operation, thereby ensuring the stable use of the slat aerator 9.
