Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to an air flotation machine foam scraping device for municipal sewage treatment. Background Art

[0002] Municipal sewage refers to domestic sewage, industrial wastewater and runoff sewage within urban areas; municipal sewage treatment refers to the process of centralized collection, treatment and discharge of urban domestic sewage, with the aim of removing or reducing harmful substances in sewage to protect the environment and human health.

[0003] As a type of municipal sewage treatment device, flotation machine is a water treatment equipment that uses a dissolved air system to generate a large number of fine bubbles in the water, 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 lower than that of water. The buoyancy principle is used to make the air float on the water surface, thereby achieving solid-liquid separation. Flotation machines are divided into super-efficient shallow flotation machines, vortex flotation machines, and horizontal flow flotation machines. They are currently used in water supply, industrial wastewater and municipal sewage treatment.

[0004] During the use of existing flotation machines, particles with bubbles generated float on the surface of the water and are scraped off manually or automatically by scrapers. Therefore, manual scraping is required because the original flotation machine does not have an automatic scraping mechanism. Moreover, the installation of a scraping device is complicated, so manual cleaning is the only option. However, flotation machines equipped with automatic scrapers are difficult to clean internally due to the inconvenience of equipment installation. Frequent disassembly and assembly will affect the structural stability of the automatic scrapers, which is not conducive to subsequent safe use. Summary of the Invention

[0029] In this embodiment, the convenient mounting seats 4 are provided in a plurality and are distributed equidistantly; specifically, the guide frame 2 and the scraping mechanism 3 can be stably mounted and fixed.

[0030] In this embodiment, the convenient mounting seat 4 includes a mounting seat body 41 for supporting the guide frame 2 and the scraping mechanism 3, a fixed clamping block 42 integrally formed at the bottom of one end of the mounting seat body 41, a stop block 43 integrally formed at both ends above the mounting seat body 41, a movable clamping block 44 assembled under the mounting seat body 41, a fixed block 45 arranged at one end of the mounting seat body 41 for fastening the movable clamping block 44, and an upper fixing stud 46 that passes through the stop block 43 to fix the guide frame 2 and the scraping mechanism 3 respectively, and a lower fixing stud 47 that passes through the fixed block 45 to fix the movable clamping block 44.

[0031] The mounting base body 41 has anti-movement strips 411 integrally formed at both ends of its upper surface. The anti-movement strips 411 cooperate with the guide frame 2 or the scraping mechanism 3 to improve the installation stability of the guide frame 2 and the scraping mechanism 3.

[0032] The lower surface of the mounting base body 41 is provided with a clamping block movable guide groove 412 for assembling the movable clamping block 44 .

[0033] Among them, the upper end of the movable clamping block 44 is integrally formed with a guide seat 441.

[0034] The fixing block 45 is fixed to the outside of the stopper 43 by screws. Specifically, it can cooperate with the lower fixing stud 47 to fix the movable clamping block 44 .

[0035] There are two upper fixing studs 46 , one of which needs to be screwed into the fixing block 45 and then pass through the stopper 43 to fix the guide frame 2 or the scraping mechanism 3 .

[0036] Therefore, through the design of the convenient mounting base, the screw mechanism and the guide frame can be installed conveniently and quickly, thereby improving the installation efficiency; the fixed clamp block and the movable clamp block on the mounting base body can provide stable support and fixing effects, thereby ensuring the stability of the guide frame and the scraping mechanism; in addition, through the design of the movable clamp block, it can be flexibly adapted to flotation machines of different specifications, thereby improving the versatility of assembly; furthermore, through the setting of the fixing studs, the guide frame and the scraping mechanism can be firmly fixed to prevent loosening during use; in summary, the flotation machine scraping device for municipal sewage treatment has the advantages of convenient installation, good stability, and strong adaptability, thereby improving the scraping effect and service life of the flotation machine.

[0037] In this embodiment, the screw mechanism 1 includes a screw seat 11, support seats 12 fixedly mounted at both ends of the screw seat 11, a screw 13 located inside the screw seat 11 and passing through the support seats 12 at both ends, a screw motor 14 fixedly mounted outside one of the support seats 12 and with its output end fixedly connected to the screw 13, a screw nut 15 mounted on the screw 13, and a guide plate 16 fixedly mounted on the screw nut 15 for mounting the scraping mechanism 3;

[0038] The upper end of the screw seat 11 is integrally formed with a guide slide 111 for assembling the guide plate 16. The lower end of the screw seat 11 is provided with screw seat side assembly grooves 112 on both sides that can cooperate with the stop block 43 and the upper fixing stud 46 for fixation. The bottom ends of the screw seat 11 are provided with screw seat bottom assembly grooves 113. The anti-movement strip 411 is assembled through the screw seat bottom assembly grooves 113, which is conducive to improving the assembly stability of the screw seat 11.

[0039] The lower ends of both sides of the guide plate 16 are fixed with side sliding seats 161 by screws. Specifically, the side sliding seats 161 are assembled with the guide slide bar 111 to smoothly drive the screw nut 15 to move during the movement of the screw 13.

[0040] In this embodiment, the guide frame 2 includes a guide frame assembly base plate 21, and a guide column 22 fixed to the guide frame assembly base plate 21 via a triangular bracket;

[0041] Among them, the lower end of the guide frame assembly base plate 21 is provided with base plate side assembly grooves 211 on both sides that can cooperate with the stop block 43 and the upper fixing stud 46 for fixation, and the bottom ends of the guide frame assembly base plate 21 are provided with base plate seat bottom assembly grooves 212.

[0043] Specifically, according to the thickness of the foam inside the flotation machine, the foam scraping plate rotation motor 33 is controlled to adjust the inclination of the foam scraping plate 31 to scrape off the foam.

[0044] It should be further explained that when the foam thickness is large, the foam scraper plate rotating motor 33 can be used to adjust the foam scraper plate 31 to be inserted perpendicularly into the water surface, thereby maximizing foam removal. When the foam thickness is small, the foam scraper plate rotating motor 33 can be used to adjust the foam scraper plate 31 to a suitable angle and insert it into the water surface, thereby not only removing the foam but also reducing the water resistance to the foam scraper plate 31. When the screw motor 14 drives the screw 3 to control the return stroke of the foam scraper mechanism 3, the foam scraper plate rotating motor 33 adjusts the foam scraper plate 31 to be parallel to the water surface, thereby ensuring a stable and rapid return stroke of the foam scraper mechanism 3.

[0045] The portion where the scraper blade rotating motor 33 is connected to the C-shaped seat 32 is provided with a reduction box 331, which is helpful to improve the control accuracy of the scraper blade rotating motor 33;

[0046] The guide post joint 34 has a sleeve 341 welded to one end of the guide post joint 34 facing the C-shaped seat 32. Specifically, the sleeve 341 is assembled with the C-shaped seat 32, allowing the C-shaped seat 32 to rotate within the sleeve 341. The guide post joint 34 can be mounted on the guide post 22, using the guide post 22 to support the foam scraping mechanism 3 and also provide guidance for the movement of the foam scraping mechanism 3.
