Description

Technical Field

[0001] This utility model relates to the field of water treatment, and in particular to an alkaline solution iron removal device. Background Technology

[0002] Alkaline solutions are aqueous solutions containing alkaline substances, typically composed of a mixture of water and alkali. In groundwater or surface water, naturally occurring iron minerals will retain their iron content in the alkaline solution after the addition of alkaline substances. Iron-containing alkaline solutions accelerate the corrosion of equipment and pipelines, leading to leaks and equipment failures, thus increasing operating costs. Therefore, removing iron can reduce corrosion and deposits in pipes, containers, and equipment, extending equipment lifespan and lowering maintenance and replacement costs. This is the key importance of alkaline iron removal devices.

[0003] However, conventional iron removal devices cannot absorb and treat the iron that has been converted into actual iron in a timely manner, which can lead to fluctuations in water quality or repeated iron contamination, affecting the final water's clarity and taste. Furthermore, conventional iron removal devices lack backwashing capabilities, which can cause the filter media or device to become clogged with impurities and sediments over long-term use, thereby reducing water flow and treatment efficiency.

[0004] Therefore, those skilled in the art have provided an alkaline iron removal device to solve the problems mentioned in the background art. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an alkaline iron removal device. This invention can discharge iron elements during operation and has a backwashing function.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An alkaline iron removal device includes a filter tank, a fixed plate, a water storage tank, and an oil separation device. A connecting pipe is fixedly installed at the lower end of the filter tank, and a return pipe is fixedly installed at the side end of the connecting pipe. A first water pump is fixedly installed between the connecting pipe and the return pipe. A magnetic filter is fixedly installed at the outer end of the connecting pipe near the connection point with the water storage tank. A water inlet mechanism is fixedly installed at the front end of the water storage tank. A pumping pipe is fixedly installed at the upper end of the oil separation device. The water inlet mechanism includes a second water pump. A water inlet pipe is fixedly installed at the output end of the second water pump. A heater is fixedly installed on the water inlet pipe near the second water pump. An alkaline washing tank is fixedly installed in the middle of the water inlet pipe, and a pipeline filter is fixedly installed at the other end of the water inlet pipe.

[0008] Furthermore, a catalyst box is fixedly installed at the top of the filter tank by bolts, and a filter plate is fixedly installed on the inner side of the filter tank near the middle.

[0009] Furthermore, an oil filter plate is fixedly installed at the outer end of the water pumping pipe, and the lower end of the water storage tank is connected to the output end of the oil separation device through a fixed pipe.

[0010] Furthermore, the water storage tank is fixedly mounted on one side of the upper end of the fixed plate, and the oil separation device is fixedly mounted on the other side of the upper end of the fixed plate.

[0011] Furthermore, the return pipe passes through the filter tank and leads to the upper end of the filter plate, and the connecting pipe passes through the water storage tank and leads to the upper part of the inner side of the water storage tank.

[0012] Furthermore, the water pumping pipe is fixedly installed inside the water storage tank near the upper end.

[0013] Furthermore, the second water pump is fixedly installed at the lower front end of the water storage tank, and the water storage tank passes through the catalytic converter and extends to the upper inner side of the catalytic converter.

[0014] This utility model has the following beneficial effects:

[0015] 1. The alkaline iron removal device proposed in this utility model involves turning on the No. 2 water pump and heating the alkaline solution when adding alkaline solution into the filter tank. This first heats the alkaline solution, which helps to accelerate the chemical reaction, promotes the precipitation and removal of iron ions, and improves the overall treatment efficiency. Then, the alkaline washing tank can adjust the pH value of the water to keep it within the most suitable range, enhance the reactivity of the alkaline solution with iron ions in the water, improve the precipitation effect, and ensure the maximum removal rate. When passing through the pipeline filter, it can effectively remove solid impurities and suspended solids in the water, further improving the water purification level. Finally, it is discharged into the catalytic box.

[0016] 2. This utility model proposes an alkaline iron removal device. After the alkaline solution is catalyzed by a catalyst box inside the filter tank, the filter plate filters out impurities in the water. After the No. 1 water pump is turned on, water is discharged from the connecting pipe into the upper part of the storage tank. The magnetic filter at the outer end of the connecting pipe can adsorb the iron elements catalyzed by the catalyst box. Through the action of the catalyst box, the dissolved iron elements in the water can be converted into a precipitable form, facilitating subsequent filtration and removal. When the valve at the outer end of the connecting pipe is closed, the No. 1 water pump will pump water to the upper part of the filter plate to clean the filter plate. The secondary rinsing process allows iron elements on the upper part of the filter plate to be fully discharged and adsorbed by the magnetic filter. When passing through the oil separation device, the water suction pipe, located at the top of the water storage tank, can suck away the oil film floating on the surface of the water storage tank. Then, the oil filter plate performs initial filtration of the oil-containing water, and the oil separation device separates the oil and water. The water will be discharged back into the water storage tank from the fixed pipe at the output end of the oil separation device. After being processed by the oil filter plate and the oil separation device, oil and impurities in the water can be effectively removed, improving water quality and ensuring water cleanliness.

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.

[0027] Reference Figures 1-5 One embodiment provided by this utility model:

[0028] An alkaline iron removal device includes a filter tank 1, a fixed plate 6, a water storage tank 7, and an oil separator 9. A connecting pipe 2 is fixedly installed at the lower end of the filter tank 1, and a return pipe 4 is fixedly installed at the side end of the connecting pipe 2. A water pump 3 is fixedly installed between the connecting pipe 2 and the return pipe 4. A magnetic filter 5 is fixedly installed at the outer end of the connecting pipe 2 near the connection point with the water storage tank 7. A water inlet mechanism 8 is fixedly installed at the front end of the water storage tank 7. A pumping pipe 10 is fixedly installed at the upper end of the oil separator 9. A catalyst box 13 is fixedly installed at the top of the filter tank 1 by bolts. A filter plate 14 is fixedly installed on the inner side of the filter tank 1 near the middle. An oil filter plate 11 is fixedly installed on the outer end of the water pumping pipe 10. The lower end of the water storage tank 7 and the output end of the oil separator 9 are connected by a fixed pipe 12. The water storage tank 7 is fixedly installed on one side of the upper end of the fixed plate 6. The oil separator 9 is fixedly installed on the other side of the upper end of the fixed plate 6. The return pipe 4 passes through the filter tank 1 and leads to the upper end of the filter plate 14. The connecting pipe 2 passes through the water storage tank 7 and leads to the upper inner side of the water storage tank 7. The water pumping pipe 10 is fixedly installed on the upper inner side of the water storage tank 7.

[0029] Specifically, after the catalytic box in filter tank 1 catalyzes the alkaline solution 13, filter plate 14 filters out impurities in the water. After turning on water pump 3, water is discharged from connecting pipe 2 into the upper part of storage tank 7. The magnetic filter 5 at the outer end of connecting pipe 2 can adsorb the iron elements catalyzed by catalytic box 13. Through the action of catalytic box 13, the dissolved iron elements in the water can be converted into a precipitable form, facilitating subsequent filtration and removal. When the valve at the outer end of connecting pipe 2 is closed, water pump 3 will pump water to the upper part of filter plate 14 for a secondary rinsing of filter plate 14. This allows the iron elements at the top of the filter plate 14 to be fully discharged and adsorbed by the magnetic filter 5. When passing through the oil separation device 9, since the water pumping pipe 10 is located at the top of the water storage tank 7, it can suck away the oil film floating on the surface of the water storage tank 7. Then, the oil filter plate 11 performs initial filtration on the water containing oil, and then the oil separation device 9 separates the oil and water. The water will be discharged back into the water storage tank 7 from the fixed pipe 12 at the output end of the oil separation device 9. After being processed by the oil filter plate 11 and the oil separation device 9, the oil and impurities in the water can be effectively removed, the water quality can be improved, and the water body can be kept clean.

[0030] Reference Figure 6 The water inlet mechanism 8 includes a second water pump 805, an inlet pipe 801 is fixedly installed at the output end of the second water pump 805, a heater 802 is fixedly installed near the second water pump 805 on the inlet pipe 801, an alkaline washing tank 803 is fixedly installed in the middle of the inlet pipe 801, and a pipeline filter 804 is fixedly installed at the other end of the inlet pipe 801.

[0031] The No. 2 water pump 805 is fixedly installed at the lower front end of the water storage tank 7. The water storage tank 7 passes through the catalytic converter box 13 and extends to the upper inner side of the catalytic converter box 13.

[0032] Specifically, when adding alkaline solution into filter tank 1, water pump 805 is turned on and heater 802 heats the alkaline solution first, which helps to accelerate the chemical reaction, promote the precipitation and removal of iron ions, and improve the overall treatment efficiency. Then, alkaline washing tank 803 can adjust the pH value of the water to keep it within the most suitable range, enhance the reactivity of alkaline solution with iron ions in water, improve the precipitation effect, and ensure maximum removal rate. When passing through pipeline filter 804, it can effectively remove solid impurities and suspended solids in the water, further improving the water purification level, and finally discharge into catalyst box 13.

[0033] Working principle: When adding alkaline solution into filter tank 1, turn on water pump 805 and heater 802 to heat the alkaline solution first, which helps to promote the precipitation and removal of iron ions. Then, alkaline washing tank 803 can adjust the pH value of the water to keep it within the most suitable range. When passing through pipeline filter 804, it can effectively remove solid impurities and suspended solids in the water, and finally discharge into catalyst box 13.

[0034] Secondly, after the catalytic box 13 in the filter tank 1 catalyzes the alkaline solution, the filter plate 14 filters the impurities in the water. After the No. 1 water pump 3 is turned on, the water will be discharged from the connecting pipe 2 into the upper part of the water storage tank 7. The magnetic filter 5 at the outer end of the connecting pipe 2 can adsorb the iron elements catalyzed by the catalytic box 13. When the valve at the outer end of the connecting pipe 2 is closed, the No. 1 water pump 3 will pump the water to the upper part of the filter plate 14 to perform a secondary flushing of the filter plate 14, so that the iron elements at the upper part of the filter plate 14 can be fully discharged and adsorbed by the magnetic filter 5. When passing through the oil separation device 9, since the water pumping pipe 10 is located at the upper part of the water storage tank 7, it can suck away the oil film floating on the surface of the water storage tank 7. Then the oil filter plate 11 performs initial filtration of the water containing oil. Then the oil separation device 9 separates the oil and water. The water will be discharged back into the water storage tank 7 from the fixed pipe 12 at the output end of the oil separation device 9.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
