Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1 to 8, the emergency safety treatment device for drinking water (hereinafter referred to as treatment device) according to the present invention includes a filter vat 11 and a filter assembly located inside the filter vat 11, wherein a water outlet 12 is provided on a side wall of the filter vat 11, a water inlet plate 24 and a water outlet plate 23 are provided at intervals from bottom to top inside the filter vat 11, and the water outlet plate 23 is installed on the filter assembly. The filtering component comprises a filtering disc 25, the filtering disc 25 is positioned between the water inlet plate 24 and the water outlet plate 23, and the filtering component is configured to ascend under the action of an upward pulling force and drive the water outlet plate 23 to ascend along the filtering barrel 11, so that water to be treated is sucked into the filtering barrel 11 through the water inlet plate 24; the water outlet plate 23 is driven to rotate and descend along the filter barrel 11 under the action of lower pressure, so that the water entering the filter barrel 11 is filtered by the filter disc 25, and the filtered water penetrates through the water outlet plate 23 and is discharged through the water outlet 12.
The filter tray 25 includes a central support 256, and a plurality of curved screens 252 and a plurality of riser screens 254 evenly distributed circumferentially around the central support 256, the height of the top edge of the riser screens 254 decreasing gradually from the inside to the outside, and the height of the bottom edge of the riser screens 254 increasing gradually from the inside to the outside. Each curved screen 252 is located between two adjacent vertical screens 254, the curved screen 252 extends from the bottom edge of one vertical screen 254 to the top edge of the other vertical screen 254, the curved screen 252 is connected to the perimeter wall of the middle support 256, the connecting lines are helical lines, and the outer edges of the curved screens 252 are located on the same circumference. The rotation direction of the filter disc 25 when descending is opposite to the extension direction of the curved filter screen 252, so that the impurities entering the filter barrel 11 are driven to be concentrated towards the top point of the space enclosed by the curved filter screen 252 and the vertical filter screen 254 in the process of rotating and pressing the filter disc 25. In other embodiments of the present invention, the height of the bottom edge of the vertical filter 254 may be configured to gradually decrease from the inside to the outside, or may be configured to extend horizontally.
In the whole filter pressing process, the filter disc 25 rotates and descends, and the bending structure of the curved surface filter screen 252 enables sundries to tend to the highest point of the curved surface filter screen 252 to move. During the rotation of the filter disc 25, the water on the lower side of the curved filter screen 252 further promotes the impurities to move towards the highest point of the curved filter screen 252, and meanwhile, the water flowing out of the vertical filter screen 254 has a scouring effect on the curved filter screen 252 from the upper side of the curved filter screen 252, so that the impurities are subjected to a force opposite to the rotation direction of the filter disc 25, and the impurities are further promoted to be collected towards the highest point of a space enclosed by the curved filter screen 252 and the vertical filter screen 254. Because the vertex position is close to the rotation center, the resistance which hinders the filter disc 25 from rotating and is generated by the sundries is minimum, and because the sundries are distributed in a mode of converging on one point, the force which is required by the sundries to hinder the filter disc 25 from moving downwards is also minimum, thereby reducing the force required by the filter pressing process, accelerating the filter pressing frequency in unit time and greatly improving the filter pressing efficiency.
Since the impurities are concentrated at the rotation center of the filter disc 25, the closer to the rotation center, the more necessary the impact force is sufficient to make the impurities in the concentrated position. The top edge of the vertical filter screen 254 is gradually reduced from inside to outside, so that the larger the area filter area of the vertical filter screen 254 close to the rotation center is, the larger the water inlet and outlet amount is, the larger the scouring capability of water flow on the curved filter screen 252 is, the smaller the force required by concentrating impurities on one point is due to the design, and the filter pressing efficiency is further improved.
Due to the matching form of the vertical surface filter screen 254 and the curved surface filter screen 252, the overall external contour of the filter disc 25 is a circle, and the sealing effect between the filter disc 25 and the filter barrel 11 is ensured. To further ensure the sealing effect, the outer periphery of the filter disc 25 is provided with a sealing ring 253.
