Description

Technical Field

[0001] This utility model relates to the field of air flotation technology, and more specifically, to a scum collection device for shallow air flotation machines. Background Technology

[0002] The scum collection device of a shallow dissolved air flotation (DAF) machine is a core component for achieving solid-liquid separation. Its design directly determines the scum removal efficiency and effluent quality. This device precisely collects the scum formed in the DAF zone, preventing backflow or retention and ensuring the continuous and stable operation of the DAF machine. The scum collection device mainly consists of a drive system, a scraper actuator, a guide adjustment component, and a scum discharge auxiliary structure. Suspended particles in the wastewater are adsorbed by microbubbles to form a scum layer that floats to the liquid surface. After the scraper-type collection device is started, the drive system drives the scraper to move at a uniform speed along the liquid surface. The scraper adheres to the surface of the scum layer, pushing the concentrated scum layer by layer to the scum trough at the edge of the pool. Through the height-adjustable scraper design, it is ensured that scum of different thicknesses is thoroughly scraped and discharged quickly through the scum discharge channel. Since the scraper is in direct contact with the scum, it is necessary to perform a collection and removal operation.

[0003] In related technologies, during the use of scum collection devices, workers typically clean and remove the adhesive residue adhering to the scraper surface periodically before use.

[0004] However, during the current use of scum collection devices, when the scraper scrapes the scum for collection, the scum adheres to the surface of the scraper. Since there is a certain time delay in the regular cleaning and removal by the staff, the scraper will carry the scum adhering to the surface back into the liquid of the air flotation machine when it is working, which affects the scraping and collection effect of the scum collection device.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Reference Figures 1-4This utility model provides a technical solution: a scum collection device for a shallow air flotation machine, including an air flotation machine 1 and a scraping removal mechanism. Chains 2 are installed on both sides of the inner side of the air flotation machine 1, and scrapers 3 are installed on the surface of the chains 2. The scrapers 3 can be scraped and removed from the surface of the scrapers 3, so that the user can remove the scum attached to the surface of the scrapers 3 during operation. This avoids the situation where the scrapers 3 carry the scum attached to the surface back into the liquid of the air flotation machine 1 during operation, thus improving the scraping and collection effect of the scrapers 3.

[0021] Reference Figures 1-4 In a preferred embodiment, the scraping removal mechanism includes a support frame 4, which is fixedly connected to both sides of the top left side of the flotation machine 1. A support opening 5 is provided on the inner side of the support frame 4, and a support seat 6 is movably connected inside the support opening 5. A removal plate 7 that contacts the scraper 3 is movably connected to the inner side of the support seat 6. A support connection mechanism is located inside the support seat 6. As the chain 2 drives the scraper 3 to scrape, collect, and push the scum on the liquid surface inside the flotation machine 1 to the left side of the flotation machine 1, the removal plate 7 contacts the surface of the upward-moving scraper 3, scraping away the scum adhering to the contact surface between the scraper 3 and the scum. During this process, the removal plate 7 drives the support seat 6 to move inside the support opening 5 along with the scraper 3. When the scraper 3 moves and contacts the scum... After the removal plate 7 separates, the support base 6 and the removal plate 7 move downwards and reset under their own gravity, preparing for subsequent contact with the scraper 3 for scum removal. The support connection mechanism includes a connecting hole 8, a connecting column 9, and a connecting plate 10. The connecting hole 8 is located inside the support base 6, and the connecting column 9 is movably connected inside the connecting hole 8. The inner side of the connecting column 9 is connected to the outer side of the removal plate 7, and the connecting plate 10 is fixedly connected to the outer side of the connecting column 9. This allows for a rotatable connection between the removal plate 7 and the support base 6, so that the removal plate 7 can move the support base 6 inside the support opening 5 when it is working. This avoids the situation where the removal plate 7 is difficult to connect with the support base 6 during use, thus improving the connection effect between the removal plate 7 and the support base 6.

[0022] Reference Figures 2-4In a preferred embodiment, threaded grooves 11 are provided on both sides of the removal plate 7, and studs 12 are threadedly connected to the inside of the threaded grooves 11. The outer side of the studs 12 is fixedly connected to the outer side of the connecting column 9, which can perform threaded fastening between the connecting column 9 and the removal plate 7. This avoids the situation where the connecting column 9 is difficult to effectively install and disassemble with the removal plate 7 during use, thus improving the installation and disassembly effect between the connecting column 9 and the removal plate 7. A support block 13 is fixedly connected to the left side of the inner side of the support base 6, which contacts the removal plate 7, and a limiting block 14 is fixedly connected to the right side of the inner side of the support base 6, which is located at the top of the removal plate 7. This allows the removal plate 7 and the support base 6 to perform flipping restriction and reset support work during operation, avoiding the situation where the removal plate 7 is difficult to maintain the reset position or excessive flipping and movement during operation, thus improving the working stability of the removal plate 7.

[0023] Reference Figures 2-4 In a preferred embodiment, a lifting hole 15 communicating with the support opening 5 is provided on the top of the support frame 4. A screw 16 is movably connected inside the lifting hole 15. The bottom of the screw 16 is connected to the top of the support base 6, which can perform lifting connection and anti-displacement work between the support base 6 and the support frame 4, and avoid the situation where the support base 6 drives the removal plate 7 to shift when working. Therefore, the lifting connection effect between the support base 6 and the support frame 4 is improved. A fixing seat 17 is fixedly connected to the bottom of the screw 16. Fixing bolts 18 threadedly connected to the support base 6 are movably connected to both sides inside the fixing seat 17. The screw 16 and the support base 6 can be installed and fixed, and the situation where the screw 16 is difficult to connect with the support base 6 when in use is avoided. Therefore, the connection effect between the screw 16 and the support base 6 is improved.

[0024] Reference Figures 2-4 In a preferred embodiment, a limiting ring 19 is movably connected to the top of the support frame 4, and the outer side of the screw 16 is threadedly connected to the inner wall of the limiting ring 19. The screw 16 provides a medium for the user to adjust the initial working height of the support base 6 and the removal plate 7, avoiding the situation where it is difficult to adjust the initial height of the support base 6 and the removal plate 7 during use. Therefore, the flexibility of the support base 6 and the removal plate 7 is improved. Mounting bolts 20 are movably connected to both sides of the top of the support frame 4. The bottom of the mounting bolts 20 is threadedly connected to the top of the air flotation machine 1, which can be used to install and fasten the support frame 4 and the air flotation machine 1. This avoids the situation where it is difficult to install and fix the support frame 4 during use, thus improving the ease of installation and fixing of the support frame 4.

[0025] Specifically, the working process or principle of this shallow air flotation machine scum collection device is as follows: During use, the support frame 4 is installed and fixed on both sides of the top left side of the air flotation machine 1 using mounting bolts 20. Then, according to the actual size of the scraper 3 and the required working trajectory, the distance between the limiting ring 19 and the support seat 6 is adjusted by rotating the screw 16 in conjunction with the hand-held limiting ring 19. At this time, the fixing seat 17, in conjunction with the fixing bolt 18, connects and fixes the screw 16 and the support seat 6. Simultaneously, the limiting ring 19, in conjunction with the screw 16, fixes the support seat 6. During the initial working height adjustment, it is important to note that the distance between the bottom of the limiting ring 19 and the top of the support base 6 and the screw 16 determines the subsequent lifting range of the support base 6. During this process, the screw 16 moves within the lifting hole 15, connecting the support base 6 and the support frame 4. Simultaneously, the connecting column 9, through the connecting hole 8 and the connecting plate 10, connects the support base 6 and the removal plate 7. At the same time, the screw 12, in conjunction with the screw groove 11, secures the connecting column 9 and the removal plate 7, ensuring the support... The support 6 drives the removal plate 7 to rise synchronously for initial working height adjustment. After the initial working height of the support 6 and the removal plate 7 is adjusted, the bottom of the limiting ring 19 contacts the top of the support 6, engaging with the screw 16 to restrict and support the adjusted support 6 and the support frame 4. When the chain 2 drives the scraper 3 to move to the left to scrape and collect the scum on the liquid surface inside the flotation machine 1, the bottom of the removal plate 7 contacts the surface of the scraper 3, which rotates with the chain 2, scraping and removing the scum adhering to the contact surface between the scraper 3 and the scum. During this process, the removal plate... 7 drives the support base 6 to move inside the support opening 5 along with the scraper 3. At this time, the removal plate 7 is tilted and flipped by the flipping force of the scraper 3, and the scum attached to the surface of the scraper 3 is fully contacted and scraped away. At the same time, the connecting column 9 moves inside the connecting hole 8 along with the removal plate 7 through the stud 12 and the screw groove 11, and flips and connects the removal plate 7 and the support base 6. When the scraper 3 moves and separates from the removal plate 7, the support base 6 and the removal plate 7 move downward and reset under the influence of their own gravity, in preparation for contacting the scraper 3 again to scrape away the scum.

[0026] It should be noted that the air flotation machine 1, chain 2 and scraper 3 are all existing devices or equipment, or devices or equipment that can be implemented with existing technology. Their power supply, specific composition and principle are clear to those skilled in the art, so they will not be described in detail.
