Description

Technical Field

[0001] The utility model mainly relates to the field of drinking water filtering equipment, in particular to a drinking water activated carbon filtering equipment. Background Art

[0002] Activated carbon is a porous adsorbent with a large surface area and strong decolorization and adsorption capabilities. It can partially or completely remove impurities from products, improve the crystalline purity of compounds such as foods and pharmaceutical intermediates, enhance product stability, and improve the appearance and color. Activated carbon has been widely used in purification fields such as food production and pharmaceutical intermediates. Activated carbon is also widely used in water purification. Activated carbon filters are currently a commonly used device for water purification. Activated carbon, such as a filter medium, is typically placed into the filter. The water is adsorbed by the activated carbon granules and filtered through a mesh before being discharged. However, the filter medium and mesh should not be used for a long time, as prolonged use can easily cause secondary contamination. Currently used filtration equipment has a simple structure, filtering water only by passing it through a container filled with activated carbon. This results in impurities in the water flowing through the upper layer to be removed, leaving the lower layer unable to perform its due cleaning ability. Furthermore, disassembling and cleaning the equipment is inconvenient. Furthermore, during the activated carbon back-filtration cleaning process, impurities filtered out by the lower activated carbon material are difficult to discharge due to the obstruction of the upper activated carbon material, resulting in incomplete cleaning.

[0037] Working principle:

[0038] When the device is in use, the water to be filtered is first introduced into the water inlet pipe 20A, so that the water flows into the water inlet hole 6 provided in the center of the support plate 2 and enters the filter barrel 1, and further the water flows through the multiple groups of the activated carbon inner net barrel 8 and the activated carbon outer net barrel 9 and then is filtered by the activated carbon filter material 11 filled therebetween. After multi-layer filtration, the water flows into the inner edge of the filter barrel 1, and is further discharged through the drain pipe 38 provided on one side of the filter barrel 1 to proceed to the next step. When the activated carbon material absorbs too many impurities and bacteria, it needs to be cleaned. At this time, the electric cylinder 15 is controlled to rise and drive the water inlet pipe support pipe 20 to rise. The insertion tube 22 is moved out of the water inlet hole 6 provided in the center of the support plate 2, and the servo motor 2 is further controlled to rotate to drive the driving gear 25 to rotate, thereby driving the driven gear 23 engaged with the rotation thereof to rotate, thereby driving the water inlet pipe support tube 20 to rotate to the water inlet hole 6 provided on one side of the fixing ring 5 and controlling the electric cylinder 15 to contract so that the insertion tube 22 is inserted into the water inlet hole 6, and further clean water is introduced into the water inlet pipe 20A, so that the water flows from each group of the activated carbon outer net barrels 9 through the activated carbon inner net barrels 8, and the activated carbon filter materials 11 filled in the two are reversely filtered to remove internal impurities, and the impurities are removed. The impurities enter the gaps between the activated carbon filter materials 11 of each group, and the rotating disk 29 is further driven by the servo motor 23 to rotate so that the rotating drain port 30 coincides with the drain port 26 opened at the bottom of the filter barrel 1, so that the water flow with impurities is discharged from the drain port 26 into the collection barrel 33 for collection, and can be further discharged through the drain pipe 38 connected to the collection barrel 33, and further by injecting water into different water inlet holes 6, the water flow is further made to enter the nozzle 42 from the water dividing ring 41 and spray out to evenly flush the gaps between the activated carbon filter materials 11 of each group, thereby filling and soaking the gaps between each activated carbon filter material 11. The foam flushing treatment enhances the cleaning effect, and flushes the impurities attached to the surface of the activated carbon outer net barrel 9 during the back filtration process to prevent the occurrence of pollutant residues. Subsequently, the rotating disk 29 is driven to rotate by the servo motor 2 37 so that the rotating drain port 30 coincides with the drain port 26 opened at the bottom of the filter barrel 1, so that the water with impurities is discharged from the drain port 26, and further the sliding connection between the activated carbon net support ring 7 and the support disk 2, support ring 3, and fixed ring 5 is made, so that it can drive the activated carbon inner net barrel 8 and the activated carbon outer net barrel 9 and the lower support ring 10 provided at the bottom of the two to slide away from the filter barrel 1, thereby facilitating deep maintenance and cleaning work.
