The present invention also relates to a method of manufacturing a foamable artificial filter material for water treatment recycling a waste glass.

Accordingly, the present invention provides an improved filtration efficiency due to a very high porosity, an improved water treatment effect due to an improved filtration rate, and a high cleaning recovery rate with only a small amount of power during backwashing for improving filtration performance, It is possible to reduce the scale of the site, so that it is easy to secure the site area (site reduction), and the construction cost can be reduced and the installation cost of the auxiliary facility can be remarkably reduced.

Further, the present invention provides a cleaning apparatus and a pulverizing apparatus having improved cleaning efficiency and pulverizing performance, and each apparatus is formed so as to minimize discharge noise to the surroundings while minimizing environmental pollution. Especially, The mechanical setting control of the firing furnace can be performed precisely and conveniently so that the manufacturing process is easy for the operator while the quality of the artificial filter medium is improved.

In addition, the present invention is characterized in that the product sorting device enables rapid and easy packaging according to the capacity or size (size) of the artificial filter media.

Generally, lake water (reservoir), river water, and sewage used in water and sewage contain various foreign matter and suspended matter generated from dirt and solids, and bacteria such as coliform bacteria are deposited in water or floated.

Therefore, the water quality of the raw water can not be used as a constant water or a heavy water, and a separate treatment process is required.

Recently, physical and chemical treatment methods such as coagulation treatment and sand filtration have been widely used.

The sand filtration method has a disadvantage in that the porosity of the homogeneous sand is 0.3 to 0.4 and the porosity is low and the filtration speed is slow (about 120 / m 3 / ㎡ to 150 / ㎥ / ㎡)

In addition, the sand filtration method requires an installation cost and a site area of the filtration facility excessively, and after a certain time, it is necessary to back-wash to recover the filtration function by contamination of the sand.

However, such a sand filtration method is problematic in that the weight of the sand is heavy (specific gravity is about 2.5), the backwashing is not smooth, and a lot of power is required for backwashing.

In order to solve this problem, anthracite (the main component of sand and anthracite) has been developed and used, but the filtration rate has been somewhat improved (about 200 / m3 / m2 day to 300 / m3 / m2 day) The installation cost and the site area of the filtration facility are excessively consumed, and after a certain period of time, the filter is required to be backwashed in order to recover the filtration function.

To improve this, a porous floating filter medium is disclosed in the patent application No. 2011-0039331 (filed on April 27, 2011) of the prior art, and the technical point thereof is to form a foam using glass and utilize it for water treatment .

However, this prior art is not compatible with the green technology because it is not a system for recycling abandoned resources such as waste glass (the related publication does not disclose cleaning related technology), and it can not be used for crushing, grinding, There is no treatment plan for the pollution and noise generation in the surrounding environment occurring during the sintering, cooling, and sorting processes.

Hereinafter, the present invention will be described in detail with reference to the drawings.

In the case of a water treatment agent, the filter material has a particle size of 10 to 70 mm , The particle size of the filtration tank is 0.3 to 2.5 mm, the density during drying is 0.3 g / cm 3 to 0.7 g / cm 3, the density during water saturation is 1.0 g / cm 3 to 1.4 g / cm 3, the porosity is 65 % To 85%, and a compressive strength of 10 kg / cm 3 to 30 kg / cm 3.

Also, as shown in FIG. 1, the method for manufacturing the artificial filter material of the present invention comprises a washing step, a pulverizing step, a mixing step, a foaming step and a firing step.

The cleaning step S100 is performed to clean the collected waste glass 1 through the cleaning device 100 to remove foreign matter or dirt.

2 to 3, the cleaning apparatus 100 includes a driving unit 111 having a rotary table 111 at one side thereof for enhancing removal efficiency of various foreign matter or dirt adhered to and adsorbed on the waste glass, And a drying unit 130 having a drain trap 131 is formed on the other side of the water-cooled and air-cooled cleaning unit 120.

The water-cooled and air-cooled cleaning unit is configured to primarily clean the waste glass by a water pump formed outside the hopper, wherein water supplied through the water pump is selectively supplied with cold water and hot water according to the summer or winter season, It is filled with water up to the upper end of the hopper opening so that the waste glass is locked.

Thereafter, a water pipe having a plurality of spray nozzles is formed in the water-cooled supply pipe connected to the water pump to form a water jet type for high pressure cleaning.

In addition, high-pressure air is supplied to one side of the water-cooling supply pipe in accordance with an optional period to communicate with the air line of the air compressor to smoothly remove stubborn bubbles.

At this time, the rotary table rotates in the circumferential direction by the driving unit, thereby assisting in even cleaning.

The drying unit is connected to the water pump and the air compressor. The drying unit is formed to spray water from the first top to the bottom. When the washed water is completely drained through the drain trap, Pressure air is sprayed to smoothly perform cleaning.

In other words, by precisely performing cleaning in the past, it is possible to eliminate the impurity source, thereby doubling the foaming performance.

Thus, the pulverizing step (S200) is pulverized through the pulverizing apparatus (200) so as to be pulverized to a fine particle size set for the washed waste glass.

4 to 8, the pulverizer 200 is formed so that a rotor 221 or a fine medium 222 is inserted into the pulverizing tank 210 so that the pulverized glass that is cleaned by rotation is 100 A dust collecting dust collecting part 220 is formed at one side of the crushing tank 210 and a sound absorbing part 230 for preventing noise is formed at the outer circumferential surface of the crushing tank 210.

Such a crushing tank is formed such that a Teflon coating is formed on its inner periphery so as to minimize the damage of the broken glass bulb glass to the crushing tank.

In addition, the rotor or the fine media are made to crush the waste glass to a predetermined size (approximately 1 to 5 cm 2), and a plurality of rotors (impellers) are branched radially with reference to an axle shaft rising in the vertical direction , And a fine bead-shaped fine media is formed so as to crush the waste plastic glass so as to increase the crushing force during rotation.

Thereafter, the primary pulverized waste glass is formed to be finely pulverized to a size of 100 to 200 mu m while passing through a drum type precision pulverizing apparatus.

At this time, a shaft shaft is formed in the right and left direction (or longitudinal direction) in the precision milling apparatus and finely pulverized to a size (100 to 200 μm) set by the rotor or fine media.

At this time, the dust collecting dust collecting part is formed at one side of the pulverizing tank so that dust generated during pulverization is collected and discarded.

At this time, the sound-absorbing portion is formed so that the crushing tank is formed in the form of a double pipe, and a sound absorbing material is filled between the double pipes to block the noise to the outside.

At this time, the sound absorbing material is formed so as to be fixed by attaching a plurality of fixing clips having a wedge type fixing member to an inner hollow tube of a double tube and then welding and fixing an outer hollow tube.

This is to prevent the sound absorbing material from flowing down in the direction of its own weight during construction and thus lowering the sound absorption efficiency.

In the mixing step (S300), the foaming agent and the additive are mixed through the mixing device 300 as shown in FIG. 9 so as to have specific gravity, strength and physical properties set for the pulverized waste glass powder.

At this time, the mixing step (S300) is performed so that a foaming agent combined with any one of calcium carbonate, carbon black, and sodium carbonate or a combination thereof is used, and as the additive, a component having properties equivalent to those of clay or clay .

In the mixing step (S300), 0.3 to 3.0 parts by weight of calcium carbonate, 0.05 to 1.0 part by weight of carbon black and 0.4 to 3.0 parts by weight of sodium carbonate are added to 100 parts by weight of pulverized waste glass powder, and the specific gravity of the artificial filter media And 0.5 to 1.0 part by weight of clay are mixed so that the density of the pulverized waste glass powder is 1.1 g / cm3 to 2.0 g / cm3, and then the continuous firing furnace 400, respectively.

Thus, the foaming and firing step (S400) is performed so as to foam the foaming glass raw material powder mixture in which the foaming agent and the additive are mixed, while being heated to a high temperature through the continuous firing furnace 400 of the refractory structure so as to be stabilized after foaming and firing .

10 to 11, the automatic thermostat 410 is installed in the continuous firing furnace 400 so that the internal heating temperature is 650 [deg.] From the inflow to the set interval, Deg.] C to 1,200 [deg.] C, and the temperature is lowered to 400 [deg.] C to 500 [deg.] C immediately after the calcination and foaming to promote annealing for stabilization of the foam and prevent internal residual stress and cracks.

At this time, in the foaming and firing step (S400), the conveyor belt 420 having the speed adjusting device 421 is formed in the continuous firing furnace 400 so that the speed setting can be controlled according to the introduced powder glass raw material powder mixture The material of the conveyor belt 420 is formed of a stainless steel material resistant to heat.

At this time, a protective net 430 is formed below the conveyor belt 420 so that the waste powder glass raw material powder mixture is not scattered or dispersed to the bottom, and the conveyor belt 420 and the conveyor belt 420 are made of titanium or tungsten The rotation roller 440 is formed to have a separate cooling chamber 450 for continuous cooling by the circulating water.

12, the artificial filter media 10 after the foaming and sintering step S400 are crushed to a predetermined size using the crusher 510, and then the product sorting device 500 is moved to a size suitable for water treatment (S500). The packaging step (S500) is a step of selecting and wrapping the bags.

At this time, in the product sorting apparatus 500, a multi-stage mesh network 520 is formed on one side, and the foamed and fired artificial filter media 10 is crushed to a size of 10 to 70 mm through a crusher 510, Or to be used as a filter medium for any of the filtration apparatuses for water, heavy water, or sewage treatment, while the other side is capable of collecting dust generated during the sorting process A dust collecting member 530 is formed.

At this time, the product sorting apparatus 500 is formed to have a conveyor transfer body for packing and sorting the selected artificial filter media into 50 L, 100 L, and 1,000 L, respectively.

Hereinafter, embodiments of the present invention will be described in more detail as follows.

The principle of foaming of the waste synthetic glass material manufacturing method in which the waste glass is recycled is that the blowing agent is added to the waste glass powder, the waste glass is surrounded by the foaming agent in the softened liquid state, the foaming agent contained therein is sintered to generate gas, And when it is stabilized and stabilized itself, it is formed to be a foamed glass.

That is, the waste glass manufacturing process of the present invention is conceptually similar to that of the prior art, because the waste plastic glass used as the basic material of the present invention has amorphous basic characteristics of glass.

However, since the physical properties of the glass are fundamentally dependent on the chemical composition of the raw material, the size, mixing ratio, selection of foaming agent, foaming and stabilization of the powder particles of the waste glass are very important factors for the efficiency of foaming. Has basically the composition of soda lime glass, and the chemical composition of the waste glass is shown in the following table.

<Chemical composition of waste glass> Item SiO2 Na2O K2O CaO MgO Al2O3 Remarks Composition ratio (%) 73.0 14.0 0.6 10.0 0.1 1.5

On the other hand, the particle size of the waste glass powder was affected by the temperature rise time.

Accordingly, the waste glass of the present invention is formed so as to be pulverized to a fine particle size of 100 to 200 microns or less in a pulverizer filled with a rotor or a fine media.

In this case, the water penetrated into the waste glass during hydration process forms a non-crosslinked material, thereby reducing the viscosity of the raw material and positively affect the softening of the waste glass during the foaming and firing process.

At this time, the water content is about 1.1%, which affects the strength and porosity depending on the weight ratio of the blowing agent.

In view of the fact that when the foaming agent is sintered before the softening of the raw material, the foaming of the foam is poor and it is difficult to obtain a homogeneous structure. As the foaming agent, 0.3 to 3.0 parts by weight of calcium carbonate, 0.05 to 1.0 part by weight of sodium carbonate and 0.4 to 3.0 parts by weight of sodium carbonate are added and when 0.5 to 1.0 part by weight of clay is added to enhance the physical properties of the artificial medium by controlling specific gravity and strength of the artificial medium, The powder is melted so as to have a density of 1.1 g / cm3 to 2.0 g / cm3, and then charged into the continuous type firing furnace 400 to be charged.

Also, in the foaming and firing process, when the raw material powder mixture flows into the continuous firing furnace, the furnace is heated to a high temperature by using gas, and the firing furnace is equipped with a temperature control device capable of automatically controlling the heating temperature to 650 to 1,200 ° C.

In this case, when the foaming temperature of the firing furnace is lower than 700 ° C., foaming is not easy because of low viscosity, and when the temperature is higher than 1,000 ° C., it is difficult to form surface pores due to high viscosity. .

In order to stabilize the foam immediately after firing and foaming, it is stabilized at 400 to 500 ° C. and then annealed to remove internal residual stress to prevent cracking of the foam.

At this time, when the foaming and sintering process is completed, the filter material is crushed to a size of 10 to 70 mm through a product sorting device, and is selected so as to be used as a water treatment carrier or a filter carrier for treating non-point pollutant.

In this case, when used as a filtration media, it is further pulverized through a crusher to have a particle size of 0.3 to 2.5 mm, a density of 0.3 g / cm 3 to 0.7 g / cm 3 when dried, a density of 1.0 g / To 1.4 g / cm 3, a porosity of 65% to 85%, and a compressive strength of 10 kg / cm 3 to 30 kg / cm 3.

&Lt; Example 1 >

Various foreign matters adhered to the collected waste glass were removed by using water and air, and the copper glass was dried and crushed to a size of 10 mm to 50 mm, and then put into a pulverizer filled with a rotor or fine media and subjected to hydration reaction for 24 hours or more To obtain a pulverized glass powder, wherein the particle size of the glass powder is 120 μm and the water content is 1.0% or more.

1.0 part by weight of calcium carbonate and 0.03 part by weight of carbon black are added to 100 parts by weight of the pulverized waste glass powder mixed with the hydrated waste glass powder and the molded body to prepare a raw material powder mixture by mixing the mixed powder and the foaming agent.

At this time, the density of the raw powder mixture was increased to about 1.3 g / cm 3, and the temperature was gradually increased by 42 ° C. per hour after pressurizing the continuous calcining furnace. The temperature of the center of the calcining furnace was adjusted to 800 ° C., followed by foaming at the foaming firing portion, In order to stabilize the foam, it is stabilized at 500 ° C in the cooling part and annealed, and then the internal residual stress is removed to finally obtain a plate-like foamed filter material.

<Comparison of physical properties of each filter material> division Dry density Moisture saturation density Porosity Remarks Common field soil 1.25 g / cm3 4.2 g / cm3 52.0% Plain sand 2.65 g / cm3 2.9 g / cm3 40.0% Example 1 0.37 g / cm3 1.15 g / cm3 75.0% Compressive strength 20kg / ㎤

As a result of measurement of the obtained foamed filter medium, the physical properties of the resulting foamed filter material were found to be 0.37 g / cm 3, a density of 1.15 g / cm 3, a porosity of 75% and a compressive strength of 20 kg / It can be seen that the characteristics of Example 1 are excellent in comparison with the physical properties of sand and Example 1.

In other words, the present invention relates to a method for manufacturing artificial filter material for water treatment, which is recycled as a raw material by pulverizing broken glass bottles corresponding to about 50% of the total glass bottle production amount, In the production of the foamable artificial filter material used in the filtration process of the tap water, the tap water, and the sewage treatment device for removing the suspended substances and solids contained in the biologically treated sewage water, It is composed of a process of selecting and packing products according to particle sizes according to the use of crushing, mixing, foaming and firing water treatment, improving the productivity and quality of products, and recycling limited resources that can be used.
