It is about.

Water quality of various water systems such as rivers, lakes, and dams, which are sources of water intake, is deteriorating due to increasingly severe environmental pollution, and advanced water treatment processes such as ozone, activated carbon, and separators are introduced in most water treatment processes to produce and supply safe drinking water. It is a driving situation.

However, due to the distrust of tap water, the ratio of installing expensive water purifiers or purchasing bottled water and using it as drinking water is increasing in each home or office. However, bottled water sold on the market is recognized as safe from bacteria or harmful substances through strict quality control, but such bottled water is often used as a source of intake of bedrock water or groundwater, and once the groundwater becomes contaminated, it is difficult to remove contaminants. Not only is it practically impossible, and it is impossible to block contaminated groundwater from moving to other places, so bottled water cannot be declared safe.

Meanwhile, interest in improving the quality of life and health has increased, so people buy and drink bottled water for the purpose of exercising, mountain climbing, various leisure activities, and drinking enough water or drinking tap water from a portable water bottle.

Hereinafter, the filter 330 incorporated in the filter receiving member 200 will be described in detail.

5 is a flowchart illustrating a filter manufacturing method according to a preferred embodiment of the present invention. The filter of the present invention is a filter to which a function capable of removing various foreign substances and bacteria contained in water, as well as hardness inducing substances such as magnesium and calcium, is added, and includes a positive charge additive, glass fiber, binder fiber, cellulose, zeolite powder, and It can be prepared including the step of mixing water and molding.

Specifically, the step of mixing the positively charged additive, glass fiber, binder fiber, cellulose, zeolite powder, and water includes: i) preparing a first mixture by mixing the positively charged additive and water, ii) glass fiber, water and Preparing a second mixture by mixing binder fibers, iii) preparing a third mixture by mixing water and cellulose, iv) adding the third mixture prepared in step iii) to the first mixture prepared in step ii). Preparing a fourth mixture by mixing, iv) preparing a fifth mixture by mixing the second mixture prepared in step ii) with the fourth mixture prepared in step iv), iv) preparing a fifth mixture, iv) 5 It includes preparing a raw material slurry mixture by mixing zeolite powder in the mixture.

In addition, the forming step includes: iv) laminating the raw material slurry mixture prepared in step iv) on a mesh belt, iv) dehydrating the raw material slurry mixture stacked on the mesh belt, ⅸ) pressing the dehydrated raw material slurry mixture. It comprises a step of pressing with a roller and ⅹ) drying with hot air.

To explain the above steps in more detail, step i) is a step of preparing a first mixture by mixing a positively charged additive and water. Here, the positive charge additive is preferably mixed in a ratio of 15 to 40 L based on 600 L of water. If the mixing amount of the positive charge additive is less than 15L, the positive charge formed on the fiber surface is insufficient and the ability to remove contaminants decreases. If it exceeds 40L, the bonding strength between the fibers is too strong and dehydration is not performed properly. The additive is preferably mixed in the above ratio.

Here, the positive charge additive may be selected from the group consisting of polyvinylamine, vinylamine copolymer, vinylamine terpolymer, and vinylamine homopolymer.

The first mixture consisting of the above mixing ratio is stirred for 45 to 75 minutes at a speed of 1300 to 1800 RPM in a stirrer.

Step ii) is a step of preparing a second mixture by mixing glass fibers, water, and binder fibers.

Here, when the glass fiber is based on 600L of water, it is preferable to mix the ratio of 1800 to 3000g and the binder fiber at a ratio of 300 to 600g.

When the mixing amount of glass fiber is less than 1800 g, not only the pores of the manufactured filter are too large, but the retention rate of zeolite decreases. On the contrary, when it exceeds 3000 g, the amount of fiber increases, making it difficult to control the basis weight and pores during filter manufacturing. It is preferable that the fibers are mixed in the above ratio. Here, it is preferable that the glass fiber has a diameter of 0.1 to 0.6 μm and a length of 5 to 50 μm.

As the binder fiber, any one or more selected from the group consisting of polyethylene, polypropylene, and polyethylene terephthalate may be used, and when the amount of the binder fiber is less than 300 g, the fibers are not entangled with each other, so it is difficult to transfer to a drying furnace. When it exceeds 600 g, the content of the glass fiber and cellulose is relatively low, so that the function as a filter cannot be sufficiently exhibited, the binder fiber is preferably mixed in the above ratio.

The second mixture having the above mixing ratio is stirred for 100 to 140 minutes at a speed of 1300 to 1800 RPM in a stirrer.

Step iii) is a step of preparing a third mixture by mixing water and cellulose.

Here, cellulose is preferably mixed in a ratio of 4000 to 6000 g based on 600 L of water.

When the amount of cellulose mixed is less than 4000 g, the zeolite retention rate is low, whereas when it exceeds 6000 g, it is difficult to manufacture a filter due to poor pore control and dehydration power, so that cellulose is preferably mixed in the above ratio. Cellulose can be obtained from various herbaceous or woody materials, and for example, wood fibers can be obtained through mechanical methods such as a grinder, a high pressure homogenizer, and a microfluidizer.

It is preferable that the cellulose has a diameter of 0.1 to 0.6 μm and a length of 3 to 10 μm. The third mixture having the above mixing ratio is stirred for 100 to 140 minutes at a speed of 1300 to 1800 RPM in a stirrer.

Step iv) is a step of preparing a fourth mixture by mixing the first mixture prepared in step iii) with the third mixture prepared in step iii), and is preferably stirred under the same conditions as in step iii).

Step v) is a step of preparing a fifth mixture by mixing the second mixture prepared in step ii) with the fourth mixture prepared in step iv), and it is preferable to stir under the same conditions as in step i).

All of the first mixture, the second mixture, and the third mixture prepared in steps i) to iii) are not mixed, and the first mixture and the third mixture are first mixed in step iv), and then a fourth mixture is prepared, and then The reason for preparing the fifth mixture by mixing the second mixture is to maximize the formation of positive charges on the cellulose surface. That is, when the first mixture in which the positive charge additive is mixed and the third mixture containing cellulose are first mixed and stirred, positive charges are formed on the cellulose surface, but the first mixture, the second mixture, and the third mixture are mixed together or the first mixture , This is because when the second mixture and the third mixture are sequentially mixed, positive charges are not sufficiently formed on the cellulose surface due to the binder fibers of the second mixture.

Step vi) is a step of preparing a raw material slurry mixture by mixing zeolite powder with the fifth mixture prepared in step v).

At this time, the zeolite powder is preferably mixed in a ratio of 2400 to 6000 g to the prepared fifth mixture, and stirred for 20 to 40 minutes at a speed of 1300 to 1800 RPM.

When the amount of zeolite powder mixed is less than 2400 g, the ability to remove the hardness material is deteriorated, and when it exceeds 6000 g, the basis weight and thickness of the filter are unnecessarily increased. Therefore, the zeolite is preferably mixed in the above ratio. Here, it is preferable that the zeolite has a diameter of 2 to 10 μm. When the diameter of the zeolite is less than 2 μm, the pores of the filter are too small because the diameter is too small, and when the diameter exceeds 10 μm, the diameter is too large to sufficiently remove the hardness material. Therefore, it is preferable that the zeolite has a diameter within the above range.

In preparing the raw material slurry mixture, the reason for the last mixing of the zeolite powder is to prevent clogging of the zeolite surface by the binder fibers.

Step vii) is a step of laminating the raw material slurry mixture prepared in step vii) on a mesh belt, and as an example, the manufacturing apparatus shown in FIG. 6 may be used.

Specifically, the raw material slurry mixture prepared in step ⅵ) is transferred to the hopper 410 by a pump (not shown), and the spray nozzle 411 connected to one side of the hopper 410 is a mesh moving at a predetermined speed. The raw material slurry mixture is sprayed onto the belt 420.

Here, it is preferable that the spray nozzle 411 of the hopper 410 is located inside the head box 430 that is blocked from the outside to form a separate space.

Step viii) is a step of dehydrating the raw material slurry mixture stacked on the mesh belt 420, and may be composed of a first dehydration step and a second dehydration step.

Specifically, the first dehydration step is the moment when the raw material slurry mixture of step ⅶ) is stacked on the mesh belt 420, the first vacuum dehydration located on the lower surface of the mesh belt 420, which is the opposite surface on which the raw material slurry mixture is stacked. It can be dehydrated with the device 431, where the vacuum pressure is preferably 50-80 cmHg.

If the first vacuum dehydration is performed at the moment when the raw material slurry mixture is stacked on the mesh belt 420 as described above, the load applied to the mesh belt 420 can be reduced, thereby reducing the maintenance cost of the device. Since the fiber is bonded by dehydration, even if the mesh belt 420 moves in a slightly inclined state, the stacked raw material slurry mixture is maintained as it is, thereby obtaining a filter having a uniform thickness.

The second dehydration step is a step of further lowering the moisture of the raw material slurry mixture that has been dehydrated and at the same time inducing more dense bonding between fibers, and a second vacuum dewatering device (440) located behind the first vacuum dewatering device (431). ), and natural gravity equation is also possible, but it is preferable to dehydrate under reduced pressure with a vacuum pressure of 10 to 40 cmHg.

Step ix) is a step of pressing the dehydrated raw material slurry mixture. The dehydrated raw material slurry mixture on the upper portion of the mesh belt 420 is transferred to a pair of pressure rollers 450 spaced at predetermined intervals and pressed.

Step ⅹ) is a step of hot air drying. In the dehydration step, as a step of completely drying some residual moisture to obtain a filter, it is preferable to perform hot air drying in a drying apparatus 460 maintained at a temperature of 100-150°C.

After that, if necessary, it can be wound with a winding device 470, and any one or more of the steps of additionally stacking the raw material slurry mixture on the mesh belt 420, the dehydration step, and the hot air drying step can be repeatedly performed. have.

Hereinafter, a method for manufacturing a filter according to the present invention will be described in more detail through specific examples.

Separately, 600 L of water and 4000 to 5500 g of cellulose were mixed and stirred to prepare a third mixture, and then the first mixture and the third mixture were mixed and stirred to prepare a fourth mixture.

Subsequently, the fourth mixture and the second mixture were mixed and stirred to prepare a fifth mixture, and 3000 to 6000 g of zeolite powder were mixed with the fifth mixture to prepare a raw material slurry mixture.
