Technical Field

[0001] The utility model relates to the technical field of air flotation equipment, in particular to an air outlet structure of an air flotation equipment with an anti-blocking structure. Background Art

[0002] Flotation refers to the use of highly dispersed tiny bubbles as carriers to adhere to pollutants in wastewater, making their buoyancy greater than gravity and upward resistance, thereby causing the pollutants to float to the water surface and form foam. The foam is then scraped off from the water surface with scraping equipment to achieve solid-liquid or liquid-liquid separation. This process is called flotation.

[0003] At present, the air outlet structure of the existing flotation equipment is a simple nozzle without an anti-blocking structure. Impurities in sewage and wastewater will enter the nozzle, causing the nozzle to be blocked. Therefore, an air outlet structure of an air flotation equipment with an anti-blocking structure is proposed. The compression spring pushes the vertical rod downward through the limit plate, so that the cover plate covers the air outlet block, which can prevent impurities from entering the cylinder and avoid its blockage. Utility Model Content

[0004] In response to the problems in the existing technology, the utility model provides an air outlet structure of a flotation equipment with an anti-blocking structure. The compression spring pushes the vertical rod downward through the limit plate, so that the cover plate covers the air outlet block, which can prevent impurities from entering the cylinder and avoid blockage.

[0005] The technical solution adopted by the utility model to solve the technical problem is an air outlet structure of an air flotation device with an anti-blocking structure, comprising an air collecting pipe, one side of the air collecting pipe is equidistantly connected to an air outlet pipe through a pipe joint, the top of the air outlet pipe is equidistantly connected to a one-way valve through a threaded groove, the top of the one-way valve is provided with a nozzle assembly, and the nozzle assembly includes a cylinder provided on the top of the one-way valve;

[0007] By adopting the above technical solution, the wastewater in the gas collecting pipe flows into the gas outlet pipe and is sprayed out from the cylinder through the one-way valve. The compression spring pushes the vertical rod downward so that the cover plate covers the gas outlet block, which can seal it and prevent impurities in the wastewater from entering.

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] The compression spring pushes the vertical rod downward through the limit plate, so that the cover plate covers the air outlet block, which can prevent impurities from entering the cylinder and avoid clogging. Figure 1-4 As shown, the air outlet structure of the flotation equipment with an anti-blocking structure described in the present invention includes an air collecting pipe 1, one side of the air collecting pipe 1 is evenly connected to an air outlet pipe 2 through a pipe joint, the top of the air outlet pipe 2 is evenly connected to a one-way valve 3 through a threaded groove, and the top of the one-way valve 3 is provided with a nozzle assembly 4, and the nozzle assembly 4 includes a cylinder 401 provided on the top of the one-way valve 3;

[0024] An air outlet block 402 is welded to the top of the cylinder 401, and a through groove 408 is opened inside the air outlet block 402. A circular layer plate 403 is fixed to the inside of the cylinder 401 by bolts, and a vertical rod 404 is sleeved inside the circular layer plate 403. The top of the vertical rod 404 is located on the top of the air outlet block 402 and is welded with a cover plate 405. The bottom end of the vertical rod 404 is located inside the cylinder 401 and is connected to a limiting plate 406 through a threaded groove. The vertical rod 404 is located between the cover plate 405 and the circular layer plate 403 and is sleeved on the outside with a compression spring 407.

[0025] When in use, the wastewater in the gas collecting pipe 1 flows into the gas outlet pipe 2 and is sprayed out from the cylinder 401 through the one-way valve 3. The compression spring 407 pushes the vertical rod 404 downward, so that the cover plate 405 covers the gas outlet block 402, which can block it and prevent impurities in the wastewater from entering.

[0026] For example, Figure 1 As shown, the utility model further includes that the side of the gas collecting pipe 1 away from the gas outlet pipe 2 is connected to the gas distribution pipe 5 through a pipe joint, and one end of the gas distribution pipe 5 is connected to the valve 6 through a threaded groove.

[0027] When in use, open valve 6 to allow compressed air to flow into the gas collecting pipe 1 through the gas distribution pipe 5.

[0028] For example, Figure 3 As shown, the present invention further includes that the top of the air outlet block 402 located at the top of the through slot 408 is provided with an outward expansion slot 409 , and the outer side of the circular layer plate 403 is equidistantly penetrated with reserved slots 410 .

[0029] During use, the opening of the outward expansion groove 409 allows the compressed air flowing out of the through groove 408 to be ejected, and the opening of the reserved groove 410 prevents the circular layer plate 403 from affecting the flow of the compressed air.

[0030] For example, Figure 3 As shown, the present invention further includes: a slot 413 is opened on the outside of the cylinder 401 ; an external threaded tube 414 is welded to the bottom end of the cylinder 401 ; and the cylinder 401 is connected to the top of the one-way valve 3 through the external threaded tube 414 .

[0031] During use, the reserved groove 410 is provided to facilitate personnel to use tools to rotate the cylinder 401 , and the provision of the external threaded tube 414 facilitates the connection of the cylinder 401 to the one-way valve 3 .

[0032] For example, Figure 3 As shown, the present invention further includes: a sealing ring 412 is glued to the bottom of the cover plate 405 , and a sealing groove 411 corresponding to the sealing ring 412 is opened on the top of the air outlet block 402 .

[0033] When in use, the sealing ring 412 and the sealing groove 411 are provided to improve the sealing between the cover plate 405 and the air outlet block 402 .

[0034] For example, Figure 4 As shown, the present invention further includes that an anti-corrosion layer 7 is provided on the outer sides of the gas collecting pipe 1 and the gas outlet pipe 2, and the anti-corrosion layer 7 is made of polytetrafluoroethylene material.

[0035] When in use, the anti-corrosion layer 7 made of polytetrafluoroethylene material enables the gas collecting pipe 1 and the gas outlet pipe 2 to have better corrosion resistance when dealing with high chloride ion wastewater.

[0036] When the utility model is in use, personnel use a pipeline to connect the valve 6 to the air supply equipment, open the valve 6 to allow the compressed air to flow through the gas distribution pipe 5 to the gas collecting pipe 1, and then flow evenly to the gas outlet pipe 2, and flow out from the cylinder 401 through the one-way valve 3;

[0037] Under normal circumstances, the compression spring 407 pushes the vertical rod 404 downward through the limit plate 406. The vertical rod 404 moves downward so that the cover plate 405 covers the air outlet block 402, thereby blocking the through groove 408. This prevents impurities in the wastewater from entering the through groove 408 and preventing it from being blocked.

[0038] After the compressed air flows into the cylinder 401 through the one-way valve 3 and the external threaded tube 414, it pushes the limit plate 406 and the cover plate 405 upward, allowing the compressed air to flow out through the through groove 408. The compressed air flowing out of the through groove 408 is guided by the external expansion groove 409 and can be sprayed into the wastewater.

[0039] Reserved grooves 410 are equidistantly provided inside the circular layer plate 403 so as not to affect the flow of compressed air. When the cover plate 405 is placed on the air outlet block 402, the sealing ring 412 enters the sealing groove 411, thereby improving the sealing between the cover plate 405 and the air outlet block 402. An anti-corrosion layer 7 made of polytetrafluoroethylene material is provided on the outside of the air collecting pipe 1 and the air outlet pipe 2, so that it has good corrosion resistance when dealing with high chloride ion wastewater.

[0040] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
