Description

Hot pressed activated carbon polypropylene composite filter device

The present invention relates to a water filtering device, in particular to a hot-press activated carbon polypropylene composite filter device.

Modern people have higher requirements for water quality. At the outlet of tap water, water purification equipment is usually installed. The water purification equipment first filters the impurities in the tap water to obtain tap water with no odor and clean water. In the water purification equipment. Usually, a filter core is added, as shown in FIG. 5, which is a common compressed activated carbon filter core 60, which is formed by mixing and sintering plastic powder and activated carbon particles, and then placed in a water filter to filter the odor. Since the plastic powder covers the activated carbon particles, the filtration area of the activated carbon particles is reduced, resulting in poor filtration effect, and the compressed activated carbon filter core 60 generally only has the effect of removing odor, and needs to be additionally used with other filter cores. The cost of purchasing is higher.

Another bulk type activated carbon filter 70 is shown in FIG. 6 , which includes a solid central filter core 71 and a peripheral filter core 72 disposed around the outer periphery of the central filter core 71. The central filter core 71 and the The outer peripheral filter 72 is a PP (polypropylene) melt-blown filter, and an accommodating space 73 is formed between the central filter 71 and the outer peripheral filter 72. The accommodating space 73 is filled with bulk granules. After the activated carbon filter 70 is placed in the water filter, the contact with the activated carbon particles when the tap water enters the accommodating space 73 can produce an odor removing effect, but the activated carbon particles are easily moved along with the water flow. The accommodating space 73 is arbitrarily displaced, and then deposited in various places, resulting in uneven distribution density of the activated carbon particles, which easily causes uneven filtration water quality. Improve the need for strengthening.

In order to solve the problem that the existing compressed activated carbon filter has a small filtering area and needs to be matched with other filter cores, and the activated carbon particles of the bulk activated carbon filter are easily moved with the water flow, the distribution density is uneven, resulting in uneven filtering water quality. The main purpose of this creation is to provide a hot-pressed activated carbon polypropylene composite filter device which is combined with a peripheral filter core of a central filter core, and a composite filter core is thermocompression bonded to PP by activated carbon powder. Propylene) melt-blown non-woven fabric, and the composite material formed by winding, the activated carbon particles can be firmly adhered and evenly distributed on the composite filter core, the filtering effect is better and the water quality can be uniformly filtered, and the filtering effect is better. .

The technical means used in the present invention is to provide a hot-pressed activated carbon polypropylene composite filter device, comprising: a central filter core having a circular tubular shape; and two filter core joints respectively coupled to the central filter core a composite filter core, which is rounded and sleeved on the outer periphery of the central filter core and the two filter core joints, the composite filter core is a carbon cloth composite polypropylene filter core; two cover bodies, The cover is respectively fixed and fixed to both ends of the composite filter.

The hot-press activated carbon polypropylene composite filter device, wherein the central filter system is a polypropylene melt blown filter.

The enhancement effect of this creation is that the composite filter core is thermocompression-bonded with PP (polypropylene) melt-blown non-woven fabric with activated carbon powder, and then wound around the center of the central filter, and the activated carbon particles can be surely adhered to the composite. The outer circumference of the filter core is not easy to seep or fall, and is evenly distributed in the composite filter core to make the water level They are all in contact with activated carbon particles, and can uniformly filter the water quality. The first filter can be used to filter the first layer of odor or chemical substance by using a composite filter with activated carbon uniformly dispersed on the surface, and then use the central filter to carry out the second impurity. Layer filtration, through two layers of filtration to achieve clean water quality and the removal of odor impurities, and the filtration effect is better.

In order to be able to understand in detail the technical features and practical functions of the present invention, and can be implemented in accordance with the contents of the specification, and further illustrated in the preferred embodiment as illustrated in the following figure, the present invention is a hot-pressed activated carbon polymerization. For the propylene composite filter device, please refer to the preferred embodiment of FIG. 1 to FIG. 4, which includes a central filter core 10, two filter core connectors 20, a composite filter core 30 and two cover bodies 40, wherein: FIG. As shown in FIG. 2 and FIG. 3, the central filter core 10 is a PP (polypropylene) melt blown circular tubular filter; the two filter joints 20 are respectively coupled to the two ends of the central filter 10; The composite filter core 30 is sleeved on the outer circumference of the central filter core 10 and the two filter core joints 20, and the composite filter core 30 is a carbon cloth composite PP (polypropylene) type filter core, which is made of carbon powder or The carbon particles are thermocompression bonded to a PP (polypropylene) melt-blown nonwoven fabric, so that the carbon powder or the carbon particles can be evenly dispersed on the surface layer, and then surrounded by a composite filter core which is wound into a circular tube; the two cover bodies 40 are annular cover bodies. And respectively, the cover is fixed to both ends of the composite filter core 30 and the central filter core 10.

A preferred embodiment of the present invention is shown in FIG. 4. The present invention can be incorporated into a water filter 50, and the water filter 50 has an inlet pipe 51 and an outlet pipe 52. The filter connector 20 is connected to the water outlet pipe 52, and when the water inlet pipe 51 introduces tap water or other water source, First, the first filter layer is filtered through the composite filter core 30. Since the composite filter core 30 is uniformly distributed with activated carbon particles, the composite filter core 30 does not cause deposition, flaking or oozing of activated carbon particles, so the water source can Uniformly passing through the composite filter core 30, thereby removing odor or chemical substances in the water source, and then flowing into the central filter core 10 to filter the impurities of the second layer, so that the foreign matter remains on the central filter core 10, and then The water outlet pipe 52 discharges the clean water, that is, completes the cycle of water filtration.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way. Anyone having ordinary knowledge in the technical field may use the present invention without departing from the technical features of the present invention. Equivalent embodiments of the local changes or modifications made by the technical content disclosed herein are still within the scope of the features of the present invention.
