Description
Technical Field
[0001] This utility model relates to the field of pure water preparation technology, and in particular to a pure water preparation device for oily wastewater that combines air flotation separation and activated carbon adsorption. Background Technology
[0002] The oily wastewater pure water preparation device that combines air flotation separation and activated carbon adsorption is a device that combines air flotation separation technology and activated carbon adsorption technology to treat oily wastewater and prepare pure water.
[0003] Existing oily wastewater pure water preparation devices that combine air flotation separation and activated carbon adsorption achieve efficient conversion from oily wastewater to pure water through the synergistic effect of these two technologies.
[0004] However, in practical applications, existing oily wastewater pure water preparation devices that combine air flotation separation and activated carbon adsorption generally use pipelines to connect the air flotation machine and the activated carbon filter to achieve the combined use of flotation separation and activated carbon adsorption. However, this connection method makes it impossible to integrate the air flotation machine and the activated carbon filter, resulting in a large area occupied by the device, which is not conducive to saving the space occupied by the device.
[0005] Therefore, this application provides a device for preparing pure water from oily wastewater by combining air flotation separation and activated carbon adsorption to meet the requirements. Utility Model Content
[0006] The purpose of this invention is to overcome the shortcomings of existing technologies and propose a device for preparing pure water from oily wastewater by combining air flotation separation and activated carbon adsorption.
[0007] To achieve the above objectives, this utility model adopts the following technical solution: a device for preparing pure water from oily wastewater using a combination of air flotation separation and activated carbon adsorption, comprising a flotation separator, and further comprising:
[0008] An integrated component is located inside the flotation separator. The integrated component includes an activated carbon filter located inside the flotation separator. The activated carbon filter has a main filter cartridge inside, and an inlet pipe is inserted inside the main filter cartridge.
[0009] A quick-release assembly is placed outside the activated carbon filter and is used to allow the activated carbon filter to slide inside the flotation machine. The quick-release assembly includes a slider connected inside the flotation machine near the activated carbon filter. A groove is provided on the activated carbon filter near the slider. The activated carbon filter is slidably connected to the flotation machine through the slider and the groove.
[0010] Furthermore, a booster pump is connected to the flotation separator, and a connecting pipe connects the booster pump to the flotation separator and the inlet pipe.
[0011] The beneficial effect of adopting the above-mentioned further solution is that it allows clean water to enter the activated carbon of the activated carbon filter, and then installs an additional support on the connecting pipe to facilitate support of the inlet pipe and ensure the stability of the inlet pipe.
[0012] Furthermore, a secondary filter cartridge is connected to the top of the activated carbon filter.
[0013] The beneficial effect of adopting the above-mentioned further solution is that the auxiliary filter cartridge is installed on the top of the activated carbon filter to prevent the activated carbon inside the flotation separator from flowing out with the filtered water and to prevent the activated carbon from contaminating the water.
[0014] Furthermore, the activated carbon filter has a sloping surface at the top.
[0015] The advantages of adopting the above-mentioned further solution are: it facilitates the discharge of clean water. At the same time, after removing the secondary filter cartridge, the activated carbon filter can be flipped over, which makes it easier for the activated carbon to be discharged along the inclined surface and facilitates the replacement of activated carbon.
[0016] Furthermore, a sliding plate is slidably connected to the inner side of the main filter cartridge, and the diameter of the sliding plate is larger than the diameter of the inlet pipe.
[0017] The beneficial effect of adopting the above-mentioned further solution is that after the water inlet pipe is separated from the main filter cartridge, the slide plate slides down along the main filter cartridge to block the outlet of the main filter cartridge, preventing the liquid remaining inside the activated carbon filter from dripping into the flotation separator when the activated carbon filter is removed.
[0018] Furthermore, a handle is attached to the top of the activated carbon filter.
[0019] The beneficial effect of adopting the above-mentioned further solution is that it makes it easier to remove the activated carbon filter from the inside of the flotation machine by handle, which helps to improve the replacement efficiency of the activated carbon filter.
[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0021] 1. By setting up an integrated component, the activated carbon filter is designed with a rectangular structure, and the clear water tank of the flotation machine is customized according to its shape to make the two shapes match perfectly. The water inlet pipe is inserted into the main filter cartridge to ensure that the clear water can be smoothly delivered to the activated carbon filter for filtration. This realizes the integrated integration of the activated carbon filter and the flotation machine, which solves the problem of traditional air flotation machines and activated carbon filters occupying a lot of space due to independent installation. This saves the equipment's floor space and improves space utilization.
[0022] 2. By setting up a quick-release component and welding a slider inside the flotation machine, the activated carbon filter is pushed along the slider towards the inside of the flotation machine. The activated carbon filter is then slidably installed inside the flotation machine by its own groove engaging with the slider. This simplifies the disassembly and assembly process of the activated carbon filter and the flotation machine. When the activated carbon filter needs to be replaced, the equipment can be quickly separated without complicated tools and cumbersome operations, significantly improving replacement efficiency and providing convenience for equipment maintenance and upgrades.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] like Figure 1 - Figure 5 As shown, this utility model provides a technical solution: a device for preparing pure water from oily wastewater using a combination of air flotation separation and activated carbon adsorption, including a flotation separator 1, and further comprising:
[0034] like Figure 1 - Figure 2 As shown, the integrated component 2 is placed inside the flotation unit 1. The integrated component 2 includes an activated carbon filter 21 disposed inside the flotation unit 1. The activated carbon filter 21 has a main filter cartridge 26 inside, and an inlet pipe 22 is inserted inside the main filter cartridge 26.
[0035] like Figure 1 - Figure 3 As shown, quick-release assembly 3 is placed outside the activated carbon filter 21 and is used to allow the activated carbon filter 21 to slide inside the flotation machine 1. Quick-release assembly 3 includes a slider 31 connected inside the flotation machine 1 near the activated carbon filter 21. A groove 32 is provided on the side of the activated carbon filter 21 near the slider 31. The activated carbon filter 21 is slidably connected to the flotation machine 1 via the slider 31 and the groove 32. By making the activated carbon filter 21 rectangular and shaping the clear water tank on the flotation machine 1 to match the activated carbon filter 21, the activated carbon filter 21 is placed on the clear water tank of the flotation machine 1. The main filter cartridge 26 is installed inside the activated carbon filter 21 using bolts to prevent… Activated carbon leaks from the bottom of the activated carbon filter 21. The inlet pipe 22 is inserted into the inside of the main filter cylinder 26, allowing clean water to be delivered to the inside of the activated carbon filter 21. This integrates the activated carbon filter 21 with the flotation machine 1, solving the problem of the large area occupied by the air flotation machine and the activated carbon filter 21, thus saving the space occupied by the device. Furthermore, by welding the slider 31 to the inside of the flotation machine 1, the activated carbon filter 21 is pushed to move inwards towards the inside of the flotation machine 1. The activated carbon filter 21 is then slidably installed inside the flotation machine 1 along the slider 31 via the slide groove 32. This connection method facilitates the quick assembly and disassembly of the activated carbon filter 21 and the flotation machine 1, thereby improving the replacement efficiency of the activated carbon filter 21.
[0036] Furthermore, such as Figure 2 As shown, a booster pump 24 is connected to the flotation separator 1. A connecting pipe 23 connects the booster pump 24 to the flotation separator 1 and the inlet pipe 22. The connecting pipe 23 is installed between the flotation separator 1, the booster pump 24, and the inlet pipe 22 using a flange, so that the inlet pipe 22 can be connected to the flotation separator 1. When the booster pump 24 is started, the clean water at the bottom of the flotation separator 1 is transported to the inside of the inlet pipe 22 through the connecting pipe 23, so that the clean water enters the activated carbon inside the activated carbon filter 21. An additional bracket is installed on the connecting pipe 23 to support the inlet pipe 22 and ensure the stability of the inlet pipe 22.
[0037] Furthermore, such as Figure 5 As shown, the top of the activated carbon filter 21 is connected to a secondary filter cartridge 25. By installing the secondary filter cartridge 25 on the top of the activated carbon filter 21, the activated carbon inside the flotation separator 1 is prevented from flowing out with the filtered water, thus preventing the activated carbon from contaminating the water.
[0038] Furthermore, such as Figure 4 As shown, the top of the activated carbon filter 21 is provided with an inclined surface. By setting the top of the activated carbon filter 21 as an inclined surface, the lowest point of the inclined surface is lower than the drain port on the flotation separator 1, which facilitates the discharge of clean water. At the same time, after removing the auxiliary filter cartridge 25, the activated carbon filter 21 can be flipped over, which facilitates the discharge of activated carbon along the inclined surface and makes it easier to replace the activated carbon.
[0039] Furthermore, such as Figure 5 As shown, a sliding plate 27 is slidably connected to the inner side of the main filter cylinder 26. The diameter of the sliding plate 27 is larger than the diameter of the inlet pipe 22. By installing the sliding plate 27 inside the main filter cylinder 26, the inner diameter of the main filter cylinder 26 is equal to the outer diameter of the sliding plate 27. When the inlet pipe 22 is inserted inside the main filter cylinder 26, it lifts up the sliding plate 27. When the inlet pipe 22 is separated from the main filter cylinder 26, the sliding plate 27 slides down along the main filter cylinder 26 to block the outlet of the main filter cylinder 26, preventing the liquid remaining inside the activated carbon filter 21 from dripping into the flotation separator 1 when the activated carbon filter 21 is removed.
[0040] Furthermore, such as Figure 4 As shown, the top of the activated carbon filter 21 is connected to a handle 33. By welding the handle 33 to the top of the activated carbon filter 21, an external lifting device is installed on the handle 33, which makes it easy for the handle 33 to remove the activated carbon filter 21 from the inside of the flotation machine 1, thus improving the replacement efficiency of the activated carbon filter 21.
[0041] Working principle: such as Figure 1 - Figure 5As shown, the activated carbon filter 21 is first moved into the clear water tank of the flotation unit 1. The activated carbon filter 21 slides along the slider 31 on the flotation unit 1 via the slide groove 32, so that the activated carbon filter 21 is installed inside the clear water tank of the flotation unit 1. The inlet pipe 22 is inserted into the main filter cylinder 26. The slide plate 27 is lifted up. The connecting pipe 23 is installed between the flotation unit 1, the booster pump 24, and the inlet pipe 22 using a flange, so that the inlet pipe 22 can be connected to the flotation unit 1. Wastewater is discharged into the flotation unit 1. A large number of microbubbles are introduced into the wastewater. These bubbles adhere to the surface of oil droplets and solid particles, reducing their apparent density and causing them to float rapidly. A scum layer forms on the water surface, and the clear water sinks to the bottom of the flotation separator 1. The scraper on the flotation separator 1 is activated to remove the scum to the waste area and then discharge it. After that, the booster pump 24 is activated to transport the clear water at the bottom of the flotation separator 1 to the inside of the inlet pipe 22 through the connecting pipe 23, so that the clear water enters the activated carbon inside the activated carbon filter 21. The clear water accumulates inside the activated carbon filter 21 and overflows upward. At this time, the auxiliary filter cartridge 25 prevents the activated carbon inside the flotation separator 1 from flowing out with the filtered clear water. The filtered water is discharged from the auxiliary filter cartridge 25 and flows along the slope of the activated carbon filter 21 to the drain outlet of the flotation separator 1. The recovery system on the flotation separator 1 recovers the filtered water.
[0042] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
