Description

Cleaner cartridge for water purification {Cartridge munufacturing machine for water cleaning}

The present invention relates to a water purification cartridge maker for producing a cartridge filter used to filter foreign matter contained in domestic water or industrial water, and more particularly, in an aqueous solution using an intake pump from an aqueous solution containing activated carbon fibers and a binder. The present invention relates to a cartridge manufacturing machine for water purification, in which a cartridge filter formed with a uniform thickness by forming a cylindrical activated carbon fiber cartridge filter by rotating a cartridge mold at the same time as suctioning a dispersion of the polymer can be produced.

Recently, due to the development of industry and overcrowding of the population, the problem of environmental pollution has emerged as an important concern.In particular, among the environmental pollution, river pollution caused by the inflow of various wastewater and the increase in the amount of detergents used in each household is considered as the destruction of the ecosystem or drinking water. Water quality problems for drinking water are seriously raised.

As a result, the water quality of the water supply source is lower than in the past, and as the water supply pipe is deteriorated, the amount of harmful components including various foreign substances is increased in domestic water or industrial water supplied to each home or factory.

In particular, contamination by organic matters such as various bacteria, which are likely to be contained in domestic tap water, is serious, and various infections such as cholera, typhoid fever, and dysentery are caused by organic matter invading through old water pipes or contamination of various microorganisms in the water storage tank. Harm to the human body by sex bacteria and bacteria, and the smell or taste caused by these contaminants make you feel unpleasant when drinking.

As one of the countermeasures that can be taken by the water user against water pollution of the water, a type of filtering water or a water purifier is generally used to filter foreign substances contained in raw water. Conventionally, activated carbon, an ion exchange resin cartridge, or a cartridge in which activated carbon and a polymer membrane filter are combined is used.

Conventional activated carbon cartridge removes impurities, odors, pigments, and bacteria by molecular adsorption of activated carbon, and in particular, the activated carbon has an excellent function of removing residual chlorine for disinfecting tap water, but its adsorption function deteriorates when used for a long time, so it is adsorbed in activated carbon. As the various pollutants are desorbed, unpurified water discharges water containing more organic matter.

In addition, the conventional activated carbon cartridge has a lot of problems in use because the various bacteria to multiply in the water purifier cartridge when the use is suspended for a while.

In addition, the ion exchange resin cartridge has a heavy metal removal function to remove and remove metal ions in water by substitution adsorption, but it is pointed out that the lack of bacteria and residual chlorine removal function such as E. coli.

Recently, since the water purification effect of activated carbon fiber is found to be superior to that of general activated carbon and polymer resin, many new manufacturing methods have been proposed, and conventionally, activated carbon fiber is a method for producing a cartridge for water purification using activated carbon fiber. A method of preparing a cartridge by heat-curing the adhesive non-woven fabric or short fibers by adding an adhesive polymer, and placing the vertical mold in an aqueous solution in which the activated carbon fibers and the water dispersible binder are dispersed, and preforming the cartridge mold using a pump. There has been a process of demolding a cartridge to produce a cartridge.

However, conventional cartridges using activated carbon fibers are composed of only heat curing or suction of activated carbon fibers, so the smoothness of the outer peripheral surface of the cartridge is reduced, and the pore size is not uniform. There is this.

In addition, since the thickness of the inner and outer circumferential surface of the cartridge is uneven, it is pointed out that the pressure difference between the cartridge filter and the water due to the water is not kept constant when installed in the water purifier, so that the pressure loss of the water purifier increases.

Accordingly, the water cartridge manufacturing apparatus of the present invention was devised to solve the above disadvantages and problems, and has a structure in which a cartridge core wound around a non-woven fabric is installed in a cartridge mold having an aqueous solution discharge port and a cartridge support at both ends. , Activated carbon fiber cartridge with excellent smoothness, constant thickness and uniform density of activated carbon fiber layer forming the outer circumferential surface of the cartridge by rotating the cartridge mold simultaneously with the suction of the aqueous solution due to the operation of the suction pump in the aqueous solution containing activated carbon fibers An object of the present invention is to provide a cartridge manufacturing machine for water purification that can be produced.

It consists of the cartridge mold 16 which consists of).

The cartridge maker 10 has a structure in which the entirety of the cartridge mold 16 is introduced into an aqueous solution containing activated carbon fibers and a dispersion such that the cartridge support 14 is rotatably coupled to an external rotor (not shown). The cartridge mold 16 in the aqueous solution is rotated by the rotation of the external rotor.

On the other hand, the cartridge core 11 mounted inside the cartridge maker 10 is located in the center of the cartridge mold 16 while the nonwoven fabric 12 is wound, and activated carbon in the aqueous solution according to the rotation of the cartridge maker 10. The fibers stick to the nonwoven fabric 12 to form an activated carbon fiber filter layer of constant thickness.

As described above, the stainless metal mesh 15 connected to the cartridge support 14 at both ends when the cartridge maker 10 rotates to form the outer circumferential surface of the cartridge mold 16 has uniformly dispersed activated carbon fibers in the aqueous solution. It serves to flow into the inside of the cartridge mold 16, the activated carbon fibers are introduced into the filter layer with a uniform density on the nonwoven fabric (12).

Next, Figure 2 shows a cartridge produced by the cartridge maker of the present invention, (a) is a schematic cross-sectional view of the cartridge, (b) is a longitudinal sectional view.

As shown, the cartridge 20 manufactured by the water purification cartridge maker 10 of the present invention has a nonwoven fabric 12 wound around the outer circumferential surface of a cylindrical cartridge core 11 having an empty inside, and the nonwoven fabric 12 On the outside, the activated carbon fiber filter 21 formed by the rotation of the cartridge mold 16 and the nonwoven fabric 22 are sequentially laminated on the outer circumferential surface thereof.
