Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without any creative effort belong to the protection scope of the present invention.
The embodiment provides a drinking water filtering device capable of sterilizing as shown in fig. 1, which comprises a filter material and a hollow shell, wherein the filter material is filled in the shell; the filter material is a mixture of a support material and spherical activated carbon. An ultraviolet irradiation device is also arranged in the shell;
a water inlet is arranged at the middle position of the top of the shell, and a water inlet filter screen is arranged between the water inlet and the filter material; a water outlet is formed in the middle of the bottom of the shell, and a water outlet filter screen is arranged between the water outlet and the filter material;
the ultraviolet irradiation device comprises a power supply, a water immersion sensor, a switch circuit and an LED ultraviolet lamp bead; the LED ultraviolet lamp beads are connected with a power supply through a switch circuit and sealed in the quartz tube; an output signal line of the water sensor is connected with a switch trigger end of the switch circuit; the water sensor is powered by a power supply; the shell is connected with a water-proof cavity, and the power supply and the switch circuit are arranged in the water-proof cavity; the water sensor is positioned below the water inlet filter screen; the quartz tube is buried in the filter material.
In this example:
the filter material is formed by mixing a support material, spherical activated carbon and a biological-grade high-molecular hot-melt material; the biological high molecular hot melt material is bonded between the support materials or the spherical activated carbon (namely, the biological high molecular hot melt material is bonded between the spherical activated carbon and the spherical activated carbon, and/or the biological high molecular hot melt material is bonded between the spherical activated carbon and the support materials).
The invention adopts the spherical activated carbon, which not only increases the surface area of the activated carbon and greatly enhances the filtering performance of the filtering device. In addition, the invention uses the biological-grade high-molecular hot-melt material to bond two adjacent activated carbons together, thereby effectively preventing the spherical activated carbon from rotating due to the pressure of water or preventing the spherical activated carbon from rotating due to the deflection of the gravity center after the spherical activated carbon adsorbs enough impurities, so that some impurities with smaller particles fall into the filtered water along with the rotation of the activated carbon. (see the attached figure 3)
The principle is that after water enters stacked spherical activated carbon, the spherical activated carbon can adsorb and remove residual pollutants in the water, but as the spherical activated carbon rotates under the pressure of flowing water flow or the center of gravity of the spherical activated carbon deflects after adsorbing enough impurities, some impurities with small particles can be introduced into the filtered water, and at the moment, biological-grade high-molecular hot-melt materials of the filtering device are bonded among the spherical activated carbon 5, so that the spherical activated carbon is effectively prevented from rotating.
The inner cavity of the shell is in a circular truncated cone shape, and the smaller bottom of the circular truncated cone is arranged below the inner cavity; the quartz tube is provided with a plurality of quartz tubes, and a single quartz tube is annular; the quartz tubes are arranged from top to bottom, and the axis of each quartz tube is superposed with the axis of the inner cavity of the shell.
The upper part in the shell is connected with an object placing plate, and the filter material is arranged below the object placing plate; a water-proof cavity is formed between the object placing plate and the top of the shell; the switch circuit and the power supply are installed on the object placing plate.
As shown in fig. 2, the power supply is an adapter externally connected with an alternating current commercial power; the switch circuit is a circuit with a switch tube as a core, or a circuit with a relay as a core (in this example, the circuit with the relay as the core can meet the requirement of a larger power load).
The wavelength range of the LED ultraviolet lamp beads is 200-280 nm.
The diameter range of the spherical activated carbon is 3-11 mm.
The working principle of the filtering device is as follows: water enters from the water inlet, and after passing through the water inlet filter screen, large granular impurities in the water can be filtered, then the water immersion sensor positioned below the water inlet filter screen senses and receives a signal of water flow, the signal is transmitted to the switch circuit, the switch circuit receives the signal and closes the power supply circuit of the ultraviolet lamp beads, so that the switch circuit is started to sterilize the water flowing in the device (in order to ensure that all areas with water flow can be sterilized, a plurality of layers of quartz tubes are arranged in the filter device, and a certain number of quartz tubes are paved on each layer),
when water flows through the stacked spherical activated carbon, residual impurities can be filtered, and the water flows into the water outlet filter screen after being filtered layer by layer and flows out of the water outlet, so that the processes of sterilizing and filtering the drinking water are finished.
In examples 1 to 6, the filtering devices have the same structure, but the difference is only in the thickness of the sponge layer and the difference of the spherical activated carbon, specifically:
in example 1, the thickness of the sponge layer was 2cm, the content of 3mm in the spherical activated carbon was 96% or more, and the balance was other diameters. In this example, the TDS pen test (for testing water quality, the smaller the value is, the better the water quality is), the TDS value of the filtered drinking water is 55 ppm.
Example 2, the thickness of the sponge layer was 2cm, the content of 7mm diameter spherical activated carbon was 96% or more, and the balance was other diameters. In this example, the TDS value of the filtered drinking water was 67ppm as measured by the TDS pen.
Example 3 the thickness of the sponge layer was 2cm, the content of 11mm diameter in the spherical activated carbon was 96% or more, and the balance was other diameters. In this example, the TDS value of the filtered drinking water was 75ppm as measured by a TDS pen.
In example 4, the thickness of the sponge layer was 3cm, the content of 3mm in the spherical activated carbon was 96% or more, and the balance was other diameters. In this example, the TDS value of the filtered drinking water was 44ppm as measured by the TDS pen.
In example 5, the thickness of the sponge layer was 3cm, the content of 7 mm-diameter spherical activated carbon was 96% or more, and the balance was other diameters. In this example, the TDS value of the filtered drinking water was 53ppm as measured by the TDS pen.
In example 6, the thickness of the sponge layer was 3cm, the content of 11mm in the spherical activated carbon was 96% or more, and the balance was other diameters. In this example, the TDS value of the filtered drinking water was 65ppm as measured by a TDS pen.
Comparative example: the structure of the filter device is the same as that of example 1, except that the spherical activated carbon is not bonded with the bio-grade high-molecular hot-melt material. Under the same experimental conditions, the TDS value of the filtered drinking water is 175ppm after the filtering compared with the TDS pen test in example 1.
In terms of sterilization effect, the higher the dosage of the UVLED, the better.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
