[0002] The advanced treatment and reuse of industrial sewage is a main way to solve the water shortage problem in China. Generally, industrial sewage can reach the discharge standard after primary physical and chemical treatment and secondary biochemical treatment. However, if the treated sewage needs to be reused, it is necessary to carry out tertiary advanced treatment. In the tertiary advanced treatment process, activated carbon is a kind of micro-quality carbon material made of carbon-containing materials, which has a black appearance, a well-developed internal pore structure, a large specific surface area, and strong adsorption ability. As a low-cost adsorbent with a large surface area and strong adsorption ability, activated carbon is currently widely used in the advanced treatment of urban sewage, industrial wastewater and the purification of polluted water sources. Activated carbon has a good removal effect on COD, SS, chromaticity, ammonia nitrogen and total phosphorus in sewage. It is generally used in combination with an adsorption tank. During the use of the adsorption tank, activated carbon particles are generally put into the adsorption tank to adsorb impurities, so as to improve the adsorption efficiency of the adsorption tank.

[0003] In the prior art, the phenomenon that the sewage after being filtered by the filter plate still contains small solids often occurs during the use of the activated carbon adsorption device, resulting in small solid impurities still adhering to the surface of the carbon filter element during the long-term use of the device, and further causing the blockage of the carbon filter element, and further reducing the sewage treatment effect of the device.

[0024] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

[0025] It should be noted that all the directional indications in the embodiments of the present application are only used to explain the relative positional relationship and movement conditions between components in a specific posture. If this specific posture changes, the directional indications will also change accordingly.

For example, "fixation" can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0027] In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present application.

[0028] Activated carbon is a kind of microcrystalline carbon material made of carbon-containing materials, which has a black appearance, a well-developed internal pore structure, a large specific surface area, and strong adsorption capacity. As a low-cost adsorbent with a large surface area and strong adsorption capacity, activated carbon is currently widely used in the advanced treatment of urban sewage, industrial wastewater, and the purification of polluted water sources. Activated carbon has good removal effects on COD, SS, chromaticity, ammonia nitrogen, and total phosphorus in sewage. It is generally used in combination with an adsorption tank. During the use of the adsorption tank, activated carbon particles are generally put into the adsorption tank to adsorb impurities, so as to improve the adsorption efficiency of the adsorption tank.

[0029] In related technologies, during the use of the activated carbon adsorption device, it often occurs that the sewage after being filtered by the filter plate still contains small solids. As a result, small solid impurities will still adhere to the surface of the carbon filter element during the long-term use of the device, which further leads to the blockage of the carbon filter element and further reduces the sewage treatment effect of the device.

[0030] To solve the problems in related technologies to a certain extent, the embodiment of the present application provides an adsorption device for an activated carbon filter tank. When the sewage inside the adsorption tank is transported to the connecting pipe 12 and enters the inside of the box body 11 and is filtered by the carbon filter element 13, activated carbon is placed inside the carbon filter element 13 to adsorb impurities in the sewage so as to achieve the purpose of purifying water. However, after being used for a period of time, small solids will appear on one side of the carbon filter element 13 adsorbed on the surface of the carbon filter element 13. At this time, the electric telescopic rod 21 is connected to an external power supply to drive it, and the scraper 22 is pushed downward. While the scraper 22 moves downward, the small solids on the surface of the carbon filter element 13 can be scraped off. The scraper 27 can scrape off stubborn impurities. It moves to the lower vertical plate 26 and contacts the baffle 24, and squeezes the baffle 24 to rotate, and squeezes the torsion spring 25 to rotate. At this time, the scraped impurities are pushed into the inside of the collection box 23. The electric telescopic rod 21 retracts to drive the scraper 22 to reset. At the same time, without the extrusion of the scraper 22, the torsion spring 25 rebounds to push the baffle 24 to rotate and reset. One side of the baffle 24 is blocked by the carbon filter element 13 to limit the rotation of the baffle 24. When the inside of the collection box 23 needs to be cleaned, only the valve 28 needs to be opened, and the impurities inside will be discharged from the inside of the sewage discharge pipe 28.

[0031] The present application will be described below with reference to the accompanying drawings and specific embodiments:

[0032] Combined with Figures 1-4, an embodiment of the present application provides an adsorption device for an activated carbon filter tank, including: a box body 11 with connecting pipes 12 provided on both sides thereof and internally communicating; an activated carbon filter element 13 disposed inside the box body 11; a cleaning assembly 2 is disposed inside the box body 11, and the cleaning assembly 2 includes: electric telescopic rods 21 symmetrically disposed on the top of the box body 11, and the output shafts thereof are inserted into the box body 11; a scraper 22 is disposed at the bottom of the electric telescopic rods 21; a collection box 23 is disposed at the bottom of the box body 11 and internally communicating; a baffle 24 is rotatably disposed on one side of the inner top wall of the collection box 23; torsion springs 25 are symmetrically disposed at the connection between the baffle 24 and the torsion springs 25.

[0033] When it is necessary to clean the surface of the activated carbon filter element 13 during use, the electric telescopic rod 21 is connected to an external power supply to drive, and the scraper 22 is pushed downward. While the scraper 22 moves downward, small solids on the surface of the activated carbon filter element 13 can be scraped off. The scraper blade 27 can scrape off stubborn impurities. When it moves to the lower vertical plate 26 and contacts the baffle 24, it squeezes the baffle 24 to rotate and squeezes the torsion spring 25 to rotate. At this time, the scraped impurities are pushed into the interior of the collection box 23. The electric telescopic rod 21 retracts to drive the scraper 22 to reset. At the same time, without the extrusion of the scraper 22, the torsion spring 25 rebounds to push the baffle 24 to rotate and reset. One side of the baffle 24 is blocked by the activated carbon filter element 13 to limit the rotation of the baffle 24.

[0034] In some embodiments, the length of the collection box 23 is the same as the side length of the activated carbon filter element 13.

[0035] During use, the collection box 23 can collect all the impurities scraped off from the activated carbon filter element 13 into the interior.

[0036] In some embodiments, the cleaning assembly 2 further includes: a vertical plate 26 disposed at the bottom of the scraper 22.

[0037] During use, the vertical plate 26 can squeeze the baffle 24 to rotate before the scraper 22 contacts the baffle 24, which can prevent the scraper 22 from squeezing the impurities and avoid the impurities from adsorbing on the scraper 22.

[0038] In some embodiments, the bottom of the vertical plate 26 is designed to be arc-shaped.

[0039] During use, the arc setting can reduce the rubbing between the vertical plate 26 and the baffle 24.

[0040] In some embodiments, the cleaning assembly 2 further includes: a scraper blade 27 disposed at the bottom of the scraper 22 and closely attached to the activated carbon filter element 13.

[0041] During use, the scraper blade 27 can clean relatively stubborn impurities to make the cleaning effect better.

[0042] In some embodiments, the cleaning component 2 further includes: a sewage discharge pipe 28 disposed at the bottom of the sewage discharge pipe 28 and communicating with the interior of the collection box 23; a valve 281 disposed on the sewage discharge pipe 28.

[0043] During use, the impurities inside the collection box 23 can be discharged by controlling the valve 281.

[0044] In some embodiments, the cleaning component 2 further includes: an inclined plate 29 disposed on the inner bottom wall of the collection box 23.

[0045] During use, the setting of the inclined plate 29 can cause the impurities to accumulate above the sewage discharge pipe 28, which is beneficial to the discharge of the impurities.
