Technical Field

[0001] The utility model relates to the technical field of air flotation machines, in particular to a connection structure of a scraper plate of an air flotation machine. Background Art

[0002] The air flotation machine is a water treatment equipment that produces a large number of fine bubbles in the water by a dissolved air system, so that the air is attached to the suspended particles in the form of highly dispersed tiny bubbles, resulting in a state with a density less than that of water. The buoyancy principle is used to make the air float on the water surface, thereby achieving solid-liquid separation. The air flotation machine is usually equipped with a scraper assembly, and the scraper plate of the scraper assembly is used to scrape off the waste residue floating on the water surface.

[0003] The existing scraper plate connection structure is connected and fixed to the mounting frame by a plurality of screws or other fasteners, and the mounting frame is further connected and fixed to the chain.

[0028] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are only used to explain the utility model but not to limit it.

[0029] Example 1

[0030] like Figure 1-4 As shown, this embodiment provides a connection structure of a scraper plate of an air flotation machine, which includes a body 110, the body 110 includes a scraper plate 130 for scraping off the slag, and a mounting frame 120 for connecting the scraper plate 130 to the air flotation machine;

[0031] The mounting frame 120 is provided with a plug-in portion 223, the scraper 130 includes a plate body 234, and a mounting seat 233 that cooperates with the plug-in portion 223 and is plugged in. The mounting frame 120 is also provided with a limiting assembly 140 for locking the plug-in portion 223 and the mounting seat 233;

[0032] The limiting assembly 140 includes an insert block 343 , which penetrates the mounting seat 233 and the plug-in portion 223 along a direction perpendicular to the plug-in of the mounting seat 233 and the plug-in portion 223 to achieve locking of the plug-in cooperation between the mounting seat 233 and the plug-in portion 223 .

[0033] Through the limiting assembly 140 in this embodiment, it is possible to avoid the need for a number of screws to complete the installation of the scraper 130, the steps are simple, and it is very convenient to disassemble and assemble the scraper 130, wherein the outer diameter of the plug block 343 is larger than the inner diameter of the first socket 231 and the second socket 221, achieving an interference fit effect.

[0034] In this embodiment, the mounting frame 120 has second sockets 221 penetrating the plug-in portion 223 on both sides, the mounting seat 233 has a first socket 231 matching the second socket 221 ; the plug block 343 is interference fit with the first socket 231 and the second socket 221 .

[0035] Through the arrangement of the first socket 231 and the second socket 221 in this embodiment, after the inserting block 343 is inserted into the first socket 231 and the second socket 221 , the mounting seat 233 of the scraper 130 cannot be detached, thereby fixing the scraper 130 .

[0036] In this embodiment, one side of the plug block 343 is connected to the abutment plate 241, and one side of the plug block 343 is provided with a retractable limit block 346. The limit block 346 and the abutment plate 241 are respectively abutted against the two sides of the mounting frame 120 to limit the plug block 343 in the first socket 231 and the second socket 221.

[0037] By providing the abutment plate 241 and the retractable limit block 346 in this embodiment, the insert block 343 cannot be detached after being inserted into the first socket 231 and the second socket 221, thereby preventing the insert block 343 from falling off, and further improving the stability of the connection to the scraper 130.

[0038] In this embodiment, a sliding groove 4431 is provided on one side of the plug block 343 away from the abutment plate 241, and two sliders 444 are slidably connected inside the sliding groove 4431. Telescopic holes 4432 that penetrate the sliding groove 4431 are provided on both sides of the plug block 343. Two limit blocks 346 are provided, which are connected to the two sliders 444 after being inserted into the two telescopic holes 4432, and a compression spring 447 is connected between the two sliders 444.

[0039] By setting the slider 444 and the compression spring 447 in this embodiment, the two limit blocks 346 extend out of the telescopic hole 4432 when the compression spring 447 is in a non-compressed state, so that the plug block 343 can not be separated from the first socket 231 and the second socket 221 through the cooperation of the limit block 346 and the abutment plate 241; wherein the distance between the limit block 346 and the abutment plate 241 is consistent with the total width of the plug-in part 223, so that after the plug block 343 is fully plugged into the first socket 231 and the second socket 221, the limit block 346 and the abutment plate 241 can fit on both sides of the plug-in part 223 to limit the plug block 343.

[0040] In this embodiment, the insert block 343 has a side with a slide groove 4431 connected to a cover plate 348 , and the cover plate 348 has a slide opening that passes through the slide groove 4431 . The outsides of the two sliders 444 are fixed with pinch blocks 345 that pass through the slide opening.

[0041] Through the arrangement of the pinching block 345 in this embodiment, the limiting block 346 can be driven to retract into the telescopic hole 4432 during relative movement, thereby the limiting block 346 can be retracted into the telescopic hole 4432.

[0042] In this embodiment, the mounting seat 233 is provided with a first guide hole 232 penetrating both sides, the mounting frame 120 is provided with a second guide hole 222 corresponding to the first guide hole 232 , and one side of the abutment plate 241 is connected with a guide bar 242 that cooperates with the first guide hole 232 and the second guide hole 222 .

[0043] By providing the guide strip 242 in this embodiment, the insertion connection between the scraper 130 and the insertion portion 223 can be more stable, thereby ensuring the stability of the scraper 130 after installation.

[0044] When the connection structure of the scraper plate of the flotation machine of the present embodiment is used, the mounting seat 233 of the scraper plate 130 is inserted into the plug-in portion 223, the push plate 241 is taken out, and the two limit blocks 346 of the plug block 343 are pushed into the telescopic hole 4432. When the limit blocks 346 are retracted, the slider 444 will compress the compression spring 447. Then the plug block 343 is passed through the second socket 221 and the first socket 231, and the two guide bars 242 are respectively passed through the first guide hole 232 and the second guide hole 222. When the plug block 343 is fully inserted, the two limit blocks 346 are not restricted, and the compression spring 447 is restored to push the two limit blocks 346 out of the telescopic hole 4432. At this time, the two The limit block 346 abuts against one side of the mounting frame 120, and the abutment plate 241 abuts against the other side of the mounting frame 120, so that the plug block 343 can be prevented from being separated from the first socket 231 and the second socket 221, thereby completing the installation of the scraper 130; when removing the scraper 130, the two pinching blocks 345 are relatively pinched, and the plug block 343 is pushed at the same time. The two pinching blocks 345 drive the two sliders 444 to slide relative to each other, so that the limit block 346 retracts into the inside of the plug block 343. At this time, the plug block 343 is not restricted and can be separated from the mounting frame 120 and the scraper 130. At the same time, the guide bar 242 is separated from the mounting frame 120 and the scraper 130. Finally, the scraper 130 can be pulled out of the plug-in portion 223.

[0045] In short, the above is only a preferred embodiment of the present utility model, and all equivalent changes and modifications made according to the scope of the patent application of the present utility model should fall within the scope of the present utility model patent.
