[0002] With the rapid development of industry, the discharge amount of industrial wastewater is increasing, which is complex in composition and contains a large amount of pollutants such as organic matter, heavy metals, nitrogen and phosphorus nutrients, and suspended solids, causing serious threat to the ecological environment. As an important wastewater treatment process, the denitrification deep bed filter can realize the dual functions of biological denitrification and filtration, has significant advantages in removing pollutants such as nitrate nitrogen and suspended solids in wastewater, and is widely used in the field of industrial wastewater advanced treatment.

[0003] In the prior art, patent number CN217418464U discloses a deep bed denitrification filter, which drives the first stirring rod and the second stirring rod to rotate relative to each other, stirs and crushes large-particle carbon source particles into small-particle carbon source, and installs a filter inside the box below the stirring element. After being filtered by the filter, the small-particle carbon source falls into the sewage, so that the sewage and the small-particle carbon source are in full contact, improving the effect of denitrification and phosphorus removal. However, in actual use, the denitrification deep bed filter is prone to accumulate dirt inside. Due to the lack of effective cleaning mechanism, a large amount of microbial membrane, algae and the like will be attached to the top of the inner wall of the filter, hindering gas exchange and affecting the normal activity of denitrifying bacteria. The bottom of the inner wall will deposit sludge and large-particle impurities or scale that have not been fully filtered, gradually causing the filter to be blocked, the water flow to be unevenly distributed, and thus reducing the denitrification efficiency and filtration effect and shortening the service life of the equipment.

[0026] Embodiment 1:

[0027] As Figures 1-6As shown, a denitrification deep bed filter for industrial wastewater treatment is provided, comprising a denitrification deep bed filter 1, a scraping mechanism is arranged inside the denitrification deep bed filter 1; the scraping mechanism comprises a lifting frame 2, which is slidingly connected inside the denitrification deep bed filter 1, a first scraper 3 is fixedly connected to the top of the lifting frame 2, a filter core 4 is installed inside the lifting frame 2, a second scraper 5 is arranged at the bottom of the lifting frame 2, a fixed rod 6 is fixedly connected to the bottom of the lifting frame 2, a connecting plate 7 is fixedly connected to the bottom of the fixed rod 6, a lifting mechanism is arranged between the denitrification deep bed filter 1 and the lifting frame 2, a dismounting mechanism is arranged between the lifting frame 2 and the filter core 4, the lifting mechanism comprises a fixed box 9, which is fixed to the inner wall bottom of the denitrification deep bed filter 1, a waterproof motor 10 is fixedly installed on one side of the fixed box 9, a rotating shaft 11 is fixedly connected to the output end of the waterproof motor 10, a first bevel gear 12 is fixedly sleeved on the outer side of the rotating shaft 11, a second bevel gear 13 is engaged at the top of the first bevel gear 12, a threaded rod 14 is fixedly connected to the top of the second bevel gear 13, a threaded sleeve 15 is threadedly connected to the top of the threaded rod 14, a fixed plate 16 is fixedly connected to the top of the threaded sleeve 15, and the fixed plate 16 is fixed to the bottom of the lifting frame 2, so that the first scraper 3 and the second scraper 5 can be lifted, the inner wall of the denitrification deep bed filter 1 can be scraped by the first scraper 3 and the second scraper 5, and the inner wall of the denitrification deep bed filter 1 can be cleaned.

[0028] As can be seen, in the above technical solution, the lifting frame 2 drives the first scraper 3 and the second scraper 5 to realize targeted cleaning of different parts of the filter. The first scraper 3 focuses on the top area of the filter, where light dirt such as algae and microbial membrane is often attached. During the lifting process, it can be completely scraped off to avoid dirt accumulation affecting gas exchange at the top of the filter and maintain a good working environment at the top of the filter.

[0029] Further, the denitrification deep bed filter 1 is fixedly connected to a drain pipe 17 on one side, and a valve 18 is installed in the drain pipe 17; as can be seen, in the above technical solution, the valve 18 is opened to discharge the treated wastewater through the drain pipe 17.

[0030] Use process: when the inside of the denitrification deep bed filter 1 needs to be cleaned, the waterproof motor 10 in the fixed box 9 is connected to the starting instruction, and the output end drives the rotating shaft 11 to rotate. The first bevel gear 12 fixedly sleeved on the outside of the rotating shaft 11 rotates. Since the first bevel gear 12 and the second bevel gear 13 are meshed with each other, the rotation of the first bevel gear 12 drives the second bevel gear 13 to rotate synchronously, and the rotation direction changes according to the meshing characteristics of the bevel gears. The threaded rod 14 fixedly connected to the top of the second bevel gear 13 rotates, and the threaded sleeve 15 threadedly connected to the top of the threaded rod 14 moves up and down along the axial direction of the threaded rod 14 under the rotation driving of the threaded rod 14. The fixed plate 16 fixedly connected to the top of the threaded sleeve 15 is fixed at the bottom of the lifting frame 2, so as to drive the lifting frame 2 to realize the lifting action. The lifting frame 2 slides up and down in the denitrification deep bed filter 1, and the first scraper 3 at the top of the lifting frame 2 can scrape off the deposits such as impurities and biofilm that may be attached to the top of the filter, so as to prevent the deposits from affecting the normal operation of the filter. At the same time, the filter core 4 installed in the lifting frame 2 is used for filtering pollutants in wastewater. With the lifting of the lifting frame 2, the second scraper 5 at the bottom can clean the bottom of the filter, and the solid particles deposited at the bottom can be scraped up for subsequent discharge. The fixed rod 6 and the connecting plate 7 serve to connect and stabilize the structure at the bottom of the lifting frame 2, so as to ensure that the second scraper 5 can work stably.

[0031] Example 2:

[0032] As Figures 1-6 shown, a denitrification deep bed filter for industrial wastewater treatment is provided, which comprises a denitrification deep bed filter 1, and a scraping mechanism arranged in the denitrification deep bed filter 1. The scraping mechanism comprises a lifting frame 2 slidably connected in the denitrification deep bed filter 1, a first scraper 3 fixedly connected to the top of the lifting frame 2, a filter core 4 installed in the lifting frame 2, a second scraper 5 arranged at the bottom of the lifting frame 2, a fixed rod 6 fixedly connected to the bottom of the lifting frame 2, a connecting plate 7 fixedly connected to the bottom of the fixed rod 6, a lifting mechanism arranged between the denitrification deep bed filter 1 and the lifting frame 2, and a dismounting mechanism arranged between the lifting frame 2 and the filter core 4. The dismounting mechanism comprises a hollow frame 19 fixedly sleeved on the outside of the filter core 4, a clamping slot 8 formed in the inner wall of the lifting frame 2, a moving plate 20 slidably connected in the hollow frame 19, a spring 21 fixedly connected between the moving plate 20 and the inner wall of the hollow frame 19, a through sliding groove 22 formed in the top surface of the hollow frame 19, a sliding rod 23 slidably connected in the through sliding groove 22, a push-pull plate 24 fixedly connected to the top of the sliding rod 23, a clamping rod 25 fixedly connected to one side of the moving plate 20, and fixedly connected between the clamping rod 25 and the clamping slot 8, and slidably connected between the clamping rod 25 and the hollow frame 19.

[0033] It can be seen that in the above technical solution, the filter core 4 of different sizes and specifications can be adapted, as long as the filter core 4 can be sleeved into the hollow frame 19, and through the elastic adjustment of the spring 21 and the cooperation of the clamping rod 25 and the clamping groove 8, reliable fixation can be achieved. This provides convenience for the filter tank to select the most suitable filter core in different industrial wastewater treatment scenarios, so that the filter tank can flexibly adjust the filtering configuration according to the change of wastewater quality and processing requirements, and widens the application range of the filter tank.

[0034] Use process: when the filter core 4 needs to be replaced, the operator pulls the push-pull plate 24, and the push-pull plate 24 drives the sliding rod 23 to slide in the through sliding groove 22 at the top of the hollow frame 19. The moving plate 20 connected at the bottom of the sliding rod 23 slides inside the hollow frame 19, at this time the spring 21 between the moving plate 20 and the inner wall of the hollow frame 19 is compressed, and the clamping rod 25 fixedly connected on one side of the moving plate 20 is separated from the clamping groove 8 opened on one side surface of the inner wall of the lifting frame 2, and the fixed connection relationship between the hollow frame 19 and the lifting frame 2 is released. Thus, the filter core 4 can be conveniently taken out from the lifting frame 2 for replacement. When installing a new filter core, reverse operation is performed, the hollow frame 19 is placed into the lifting frame 2, the clamping rod 25 is clamped into the clamping groove 8 under the elastic force of the spring 21, and the installation and fixation of the filter core are completed.

[0035] Obviously, the above embodiments are only examples for the purpose of clear illustration, and are not limitations on the embodiments. For those skilled in the art, other different forms of changes or variations can be made on the basis of the above description. All the embodiments do not need to be exhausted here, and the obvious changes or variations derived therefrom are still within the protection scope of the present application.
