Description

Technical Field

[0001] The utility model relates to a recovery device, in particular to a surfactant recovery device, and belongs to the technical field of polystyrene remodeling. Background Art

[0002] Polystyrene is a homopolymer of styrene and a general-purpose thermoplastic plastic. It does not decay, degrade or transform over time in the natural environment, and directly pollutes the environment. Therefore, the recycling and utilization of waste polystyrene raw materials has a dual meaning, that is, the waste treated purifies the environment, and renewable resources can be developed to reuse the waste. At present, in the process of polystyrene remodeling resin, in order to ensure the quality of the material, the material needs to be rinsed and cleaned first, and the wastewater contains a large amount of surfactants. Direct discharge will cause water pollution, so the surfactant needs to be recovered;

[0003] For example, the utility model in the prior art with application number 202122727716.X discloses a multi-stage floating surfactant recovery device, which uses a blower and an aeration disk to aerate the sewage to form a foam layer in the sewage, and the surfactant gathers in the foam layer; the foam layer rises with the water level of the sewage, and is discharged from the cylinder through an overflow assembly and an overflow branch pipe to recycle the foam layer.

[0004] Similar to the above application, there are still some shortcomings:

[0005] There are a certain amount of particulate impurities in the stored water, and the wastewater cannot be filtered and cleaned during the recycling process, so the functionality is low. In addition, after the foam passes through the overflow component, the foam cannot be quickly broken, which affects the recovery rate of the surfactant;

[0006] Therefore, a surfactant recovery device is designed to optimize the above problems. Utility Model Content

In addition, it is used in conjunction with a cleaning mechanism composed of an air guide box, an axle, an impeller and a lower scraper inside the upper cylinder body. When the device is ventilated by an air pump, the lower scraper can be automatically controlled to clean the impurities on the surface of the filter screen to avoid clogging of the filter screen, thereby ensuring the filtering effect during use.

[0025] like Figure 1-Figure 4As shown, this embodiment provides a surfactant recovery device, including an upper cylinder 1, an overflow assembly 2 located at the top of the upper cylinder 1, and an overflow pipe 3 installed on the side of the upper cylinder 1 and located at the top of the overflow assembly 2, a lower cylinder 4 is provided at the bottom of the upper cylinder 1, the diameter of the lower cylinder 4 is larger than the diameter of the upper cylinder 1, a liquid inlet pipe is provided at the bottom end of the lower cylinder 4, a filter screen 5 is horizontally fixed at the bottom end of the upper cylinder 1, and the bottom surface of the filter screen 5 is located at the same horizontal plane as the bottom end of the upper cylinder 1, a cleaning mechanism is provided at the bottom of the filter screen 5, an air pump 11 is installed on the outer side of the upper cylinder 1, an aeration plate 10 is installed on the inner bottom of the upper cylinder 1, the output end of the air pump 11 is connected to the aeration plate 10 through a conduit, and a collecting mechanism is provided on the outer side of the lower cylinder 4.

[0026] The general working principle is as follows: when in use, the waste liquid containing the surfactant is injected from the lower cylinder 4, and then the waste liquid enters the interior of the upper cylinder 1 through the filter screen 5. The filter screen 5 filters and blocks the large particles of impurities in the waste water, and then the air pump 11 is used to pass gas into the interior of the aeration plate 10, and bubbles are generated inside the upper cylinder 1. The surfactant in the waste liquid rises with the bubbles and gathers at the gas-liquid interface, reaching the top of the solution body to form a foam layer. As the bubbles increase, the bubbles are pierced by the serrations on the overflow component 2, enter the interior of the overflow component 2, and are discharged outward through the overflow pipe 3, completing the recovery of the surfactant.

[0027] In this embodiment, the cleaning mechanism includes an air guide box 6, a shaft 7, an impeller 8 and a lower scraper 9. The air guide box 6 is installed inside the upper cylinder 1. The output end of the air pump 11 is connected to one side of the air guide box 6, and the other side of the air guide box 6 is connected to the aeration plate 10 through a conduit. The shaft 7 is vertically mounted inside the air guide box 6, and the shaft 7 extends to the bottom of the filter 5. The lower scraper 9 that fits the surface of the filter 5 is fixed to the bottom of the shaft 7, and the impeller 8 is fixed inside the air guide box 6 and on the shaft 7.

[0028] Local working principle: After long-term use, floating impurities will adhere to the bottom of the filter 5, causing blockage of the filter 5, so it needs to be cleaned by a cleaning mechanism. After the gas discharged by the air pump 11 enters the interior of the upper cylinder 1, it first enters the air guide box 6 and applies thrust to the impeller 8 on the shaft 7. At this time, the shaft 7 will rotate. The rotation of the shaft 7 drives the lower scraper 9 to clean the surface of the filter 5 and sweep the impurities to the outside to ensure the filtering effect. The impurities float on the top of the lower cylinder 4 and accumulate. When more impurities are accumulated, it will be opened for cleaning.

[0029] In this embodiment, the top end of the shaft rod 7 extends to the top of the overflow assembly 2 , and an upper scraper 12 is horizontally fixed to the top end of the shaft rod 7 , with a gap between the upper scraper 12 and the top of the overflow assembly 2 .

[0030] Partial working principle: During the rotation of the shaft 7, the upper scraper 12 will be driven to rotate at the same time. The upper scraper 12 pushes the bubbles on the top of the overflow component 2 to the outside and breaks the bubbles, thereby increasing the recovery rate of the surfactant.

[0031] In this embodiment, the collecting mechanism includes a collecting box 13 and a partition plate 14. The partition plate 14 is inclined at the inner top of the collecting box 13. The top of the outer side of the lower cylinder 4 is connected to the collecting box 13, and the connecting port between the lower cylinder 4 and the collecting box 13 is located below the partition plate 14. The bottom end of the overflow pipe 3 extends to the top of the collecting box 13.

[0032] Local working principle: When a large amount of impurities are accumulated at the top of the lower cylinder 4, the switch valve between the lower cylinder 4 and the collecting box 13 is opened, and the impurities flow into the interior of the collecting box 13 for storage and discharge, and the surfactant recovered on the overflow pipe 3 directly falls into the top of the collecting box 13 for storage.

[0033] In this embodiment, the top end of the lower cylinder 4 is an inclined surface, the bottom end of the upper cylinder 1 is vertically inserted into the lower cylinder 4, and a distance is left between the bottom end of the upper cylinder 1 and the inner top of the lower cylinder 4.

[0034] Partial working principle: The inclined design of the top of the lower cylinder 4 can facilitate the collection of impurities to the top and facilitate the discharge of impurities.

[0035] In this embodiment, transparent windows are provided on the top and bottom of the outer side of the collecting box 13 and the outer side of the lower cylinder 4, and the transparent windows are all located on the same side.

[0036] Partial working principle: Through the provision of a transparent window, the conditions inside the lower cylinder 4 and the collecting box 13 can be observed, which is more practical.

[0037] In this embodiment, a support plate is fixed to the bottom end of the lower cylinder 4, and an anti-slip pad is provided at the bottom of the support plate.

[0038] Partial working principle: The setting of the support plate increases the supporting area of ​​the bottom end of the lower cylinder 4 and ensures the stability of the equipment.
