The present invention relates to a stirring device having excellent mixing reactivity used in the water purification process for treating contaminated water, such as contaminated river water, lake water, drinking water, and wastewater, and more specifically, instead of the conventional stirring type using a stirring blade. In addition, the mixing reactivity, which allows the treatment water to improve the cohesive mixing properties of the flocculant and the like through rapid vortex generation and collision of the treated water while moving across the agitator tank, can significantly reduce the operating cost of the equipment. An excellent stirring device.

In the water purification process that treats contaminated water such as contaminated river water, lake water, drinking water, and waste water, the contaminants, for example, organic matters are flocculated and treated to purify the water and to purify the water. It is essential to use a stirring tank (tank) into which flocculants and disinfectants are added.

However, until now known stirring tanks have been used to mix the treated water and the input agent using a stirring blade in order to mix the treated water and the added flocculant, disinfectant and the like.

For example, FIG. 1A shows a conventional stirring tank, but such a stirring tank 100 is not shown in detail in the drawing, but between treatment tanks such as various inflow tanks, sedimentation tanks, and disinfection tanks in water and sewage treatment plants. It may be a concrete structure disposed in accordance with the water treatment process.

Alternatively, in the case of a simple water treatment plant, a stirring vessel (agglomeration reactor) of a resin structure may be used.

On the other hand, in most of the stirring tank 100, the motor 130 is installed on the fixed base 120 installed across the tank structure 110, the treated water (filled inside the tank structure 110 directly below) ( The stirring blade 150 is provided on the drive shaft 140 immersed in W).

Therefore, in the conventional stirring tank 100, when the treated water (W) flows into the tank structure 110, a flocculant, a disinfectant, and the like are introduced using a mechanism or facility not shown, and the motor 130 As the stirring blade 150 was rotated by driving, the treatment water and the input chemicals such as the flocculant were mixed and reacted to perform the water treatment.

However, in the stirring tank 100, that is, the stirring tank 100 of the flocculation reaction, the treated water and the dosing agent and the like are mixed during the rotation operation of the stirring blade 150, and thus the stirring blade as shown in FIG. 1B. Since the contaminant particles (A), flocculant particles (B), and other substance particles (C) contained in the treated water are mixed in the same direction and flow in almost the same direction only in the advancing direction (arrow) of 150, The dispatch mix between the two was inferior.

In addition, in order to rotate the stirring blade 150 in the tank structure in the state in which the treated water (W) is used, since the motor 130 having a capacity of at least 50 horsepower or more must be used, the operating cost of the stirring tank is increased annually. It is quite spent.

In addition, since there is no other mechanism for mixing and stirring the treated water and the chemicals in the tank except for the stirring vane, there are various problems such as stopping the entire operation of the stirring tank even when only the motor is stopped.

Accordingly, by using a rapid vortex of the treated water which forcibly generates a mixed reaction of the treated water and the injected chemical in a stirring vessel (stirrer), particles of pollutants (organic matter, etc.) to be purified contained in the treated water are used. There has been a need for a stirring device that can increase the treatment efficiency of the agitator tank with sufficient collision reaction of the injected chemical particles and to reduce the running cost more due to the mixing means moving almost linearly.

The present invention has been made in order to improve the conventional problems as described above, its purpose is to move across the agitator tank instead of using a conventional stirring blade, such as a coagulant injected through rapid vortex generation and collision of the treated water Since it is more actively mixed with the treated water, the mixing agility is further improved, and in particular, the mixing reactivity is excellent, which makes it possible to save power compared to using the existing stirring blades and to significantly reduce the operating cost of the equipment. It is to provide a stirring device.

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

In FIG. 2, the whole structure of the stirring apparatus 1 excellent in the mixing reactivity which concerns on this invention is shown in perspective view.

For example, as shown in FIG. 2, the stirring device 1 having excellent mixing reactivity of the present invention includes a stirring vessel structure 10 into which treated water is largely introduced and stored therein and chemicals such as a flocculant are introduced, and A plurality of carts 30 installed on both sides of the upper part of the structure 10 so as to move forward and backward and vertically under the connection pipe 52 connected between the cart means 30 extends near the bottom of the agitator structure. Is coupled to the support rod 54 is installed and the outer surface of the support rod 54 includes a mixing means 50 having a vortex generating plate 56 to forcibly generate vortex in the treated water during the movement of the support rod to maximize the coagulation stirring It is composed.

Therefore, the stirring device 1 having excellent mixing reactivity of the present invention is an example of a connecting pipe 52 connected between the bogie means 30 when the bogie means 30 moves from both bottom walls 10a of the agitator concrete structure 10. For example, the supporting rods 54 vertically installed in three rows of connecting pipes 52a, 52b, and 52c move integrally, and the vortex generating plates 56 installed therein are forced while passing through the treated water stored in the stirring tank. This process causes rapid vortices to cause agglomeration and agitation of treated water, input particles such as flocculants or disinfectants, and contaminants (organic substances, etc.).

In addition, in the case of the stirring device 1 having excellent mixing reactivity of the present invention, when the stirring blade 150 is conventionally used (see FIG. 1), the capacity of the driving motor 130 is required at least 50 horsepower or more, In the case of the present invention, since only the linear movement of the bogie means 30 needs to be possible, the motor capacity for driving the bogie means is greatly reduced, which makes it possible to considerably reduce costs in consideration of the annual operating costs.

In addition, in the case of the present invention, since the connection pipe, the support rod, and the vortex generating plate are simply connected to each other by welding, they provide another advantage of less equipment defects than the existing stirring blades.

At this time, the stirring vessel structure 10 is composed of a rectangular concrete structure, the trolley means 30 is arranged to be moved back and forth on both side walls of the concrete structure.

On the other hand, as shown in Figures 3 and 4, in the stirring apparatus 1 of the present invention, the cart means 30, the rail 32 and the rail (installed on the upper floor 10a of both side walls of the concrete structure) A trolley body 38 having a moving wheel 36 for moving to a moving means 34 installed at an upper portion along the upper portion 32 and the vortex generating plate 54 of the mixing means are installed on the trolley body 38. It is made of a connection box 40 to be connected.

The moving means 34 is connected to the moving wheels 36 and is connected to the drive shaft 34a rotatably installed as a bearing on the bogie body and the drive chain 34c connected to the driven sprocket 34b on the drive shaft. ) And the drive chain 34c are connected to each other, and the drive sprocket 34f is connected to the motor 34e in the gear box 34d on the upper portion of the bogie body.

Therefore, when the motor 34e of the moving means 34 is driven to drive the drive chain 34c by the drive sprocket 34f, the bogie body 38 is driven while the drive shaft 34a on which the driven sprocket 34b is fixed is driven. Both movement wheels 36 of) move along the rail 32.

At this time, the motor 34e of the moving means enables the reciprocating motion of the bogie body 38 of the bogie means 30 to repeat forward and backward as forward and reverse motors.

Accordingly, the connecting pipe 52 connected between the cart means 30, that is, the first to third row connecting pipes 52a, 52b, 52c and the supporting rods 54 fixed perpendicular to the connecting pipes 52, respectively. They move through the treatment water W in the agitation tank integrally with the movement of the bogie means.

As a result, the vortex generating plates 56 installed on the support rods 54 generate a rapid vortex of the treated water, thereby expanding the collision of contaminant particles and the injected chemical particles such as a flocculant during the water treatment, and thus increasing the amount of collision through mixing. It is to improve reflection.

At this time, the connecting pipe 52 is shown in three rows, but if the length is long, it is also possible to install only the central connecting pipe (52b).

However, in order to increase the cohesive mixing property, three rows will be most suitable, because if too few or too many are installed, the vortex generation width for the coagulation reaction is small or vice versa, and the weight increases and the load is applied during the movement.

On the other hand, as shown in Figures 5 and 6, the support rods 54 installed in the connecting pipes (52a, 52b, 52c), respectively, so that the vortex generating plates 56 at different angles to maximize the vortex generation width It is preferable to be installed as.

For example, as shown in FIG. 6, the vortex generating plate 56 provided in the support rod 54 side of a 1st row connection pipe is installed inclined about 45 degrees (a) clockwise from a center line, and the 2nd The vortex generating plate 56 installed on the support rod 54 of the thermal connection pipe 52b. It is installed at 180 ° (b) horizontally, the vortex generating plate 56 provided on the support shelf 54 of the third row connection pipe (52c) is installed inclined about 45 ° (c) counterclockwise from the center line.

Therefore, since the installation angles of the vortex generating plates 56 are differently installed according to the first to third row connectors, the vortex generation or the width of the treated water at the time of advancing and reversing the supporting rod will be greatly amplified.

In this case, as shown in FIG. 3, the vortex generating plate 56 is integrally installed in the longitudinal direction of the supporting rod 54.

Therefore, as shown in FIG. 6, the stirring device 1 of the present invention is a pharmaceutical particle (B) or other substance particles such as a contaminant particle (A) and a flocculant in FIG. Since C) collides violently with the treated water vortexing inside the agitator vessel structure, it collides with each other to make the agitation for the aggregation reaction of the particles very high.

Next, Figure 7 shows another form of the vortex generating plate 56 according to the present invention, the vortex generating plate 56 provided on the support rod is shorted to the support rod, for example, several in the longitudinal direction, for example about two Is attached, and the upper and lower vortex generating plates 56a and 56b have different angles with respect to the same support bar 54.

Therefore, as shown in FIG. 7, when the directions of the vortex generating plates 56a and 56b are different from each other in the longitudinal direction of the supporting rod 54, the vortex issuing directions of the upper and lower portions of the treated water in the tank are different. In this case also, the flocculation agitation will be increased.

And, although not shown in a separate drawing, it will be possible to install inclined in the horizontal direction with respect to the vortex generating plate support rods.

Meanwhile, as shown in FIGS. 2 and 5, a flexible air inlet pipe 42 connected to an air compressor 42a is connected to the connection box 40 of the cart means 30, between the connection boxes. The connecting rod 52 and the support rod 54 connected in the vertical direction are composed of ventilated pipes, and an air nozzle 58 for injecting air to the bottom of the support rod 54 is additionally installed. It is also possible.

Therefore, as shown in FIGS. 2 and 3, the high pressure air supplied through the flexible air inlet pipe 42 while the air compressor 42a is operated is connected to the connection box 40 on the bogie body 38. Fed through the connecting pipes 52a, 52b and 52c and the support rod 54 and finally sprayed from the bottom 10b through the air nozzle 58, in this case being sedimented and fixed on the bath bottom 10b. It will enable the dispersion of sediment which is liable to decay, and be treated with dosing chemicals, thereby increasing the water treatment efficiency of the stirring bath.

And, the air spray will facilitate the purification of the treated water.

Next, FIG. 8 illustrates another modified example of the stirring device 1 according to the present invention. As shown in FIGS. 8A and 8B, the rails 32 on both bottom walls of the bottom of the stirring vessel structure 10 are formed. The support plate 70 is installed on the upper portion, and the center of the support plate 70 is hinged 72 through the long hole 72a on the upper bottom 10a of the stirring vessel structure 10.

8B and 8C, a driving cylinder 74 is connected to the center of the support plate 70 in a horizontal direction, and both ends of the support plate 70 having the rails 32 installed on both sides thereof. Each of the auxiliary rails 76 are installed in the rail is provided to move in the horizontal direction.

At this time, as shown in Figure 8c, the auxiliary rail 76 is a rail block (76a) installed on the bottom of the structure and the movable block is mounted on the upper portion, the support plate 70 is fixed to the upper block ( 76b).

Therefore, when the driving cylinder 74 connected to the center side of the support plate 70 is driven, the support plate 70 moves left and right, and the cart means 30 on the upper rail 32 moves left and right. In addition, it is possible for the connecting pipe and the support rod and the vortex generating plate between the bogie means to have a movement path as shown in FIG.

That is, the movement paths of the vortex generating plates in the stirring vessel structure 10 are different from each other when moving forward and backward, which in turn causes the moving direction of the vortex generating plate 56 to move in the Z-shape of the zigzag. Directional movement will maximize the vortex generation width in the treated water W, thereby improving the cohesive agitation.

Next, Fig. 9 shows another modification of the mixing means in the stirring device of the present invention.

That is, as shown in FIG. 9, the support rod 54 is rotatably connected to the lower portion of the connecting pipe 52 as shown in the drawing, and the lower air nozzle 58 'of the support rod 54 has a counterclockwise end. Constantly bent in the clockwise or clockwise direction.

Accordingly, as the air is injected through the bent air nozzle 58 ', the supporting rod 54 is rotated by the repulsive force, and in this case, the vortex generating plates 56a and 56b (including 56 in FIG. 3) fixed to the supporting rod. As it rotates, the vortex generation width is increased to increase the stirring effect.

In addition, as shown in FIG. 9, holes 57 may be formed in the vortex generating plates 56a and 56b (including 56 in FIG. 3).

In this case, a part of the treated water W passes through the holes of the vortex generating plate, and the vortex generating plate progresses or rotates at different angles, and the vortex generation increases and decreases by that amount, passing through the hole 57. The water and the treated water behind it will collide again to increase agitation.

Accordingly, in the case of the stirring device 1 having excellent mixing reactivity of the present invention, it is possible not only to improve the mixing agent mixing mixing agitation property of the treated water without using the existing stirring blade, but also to enable low-cost operation of the stirring equipment. .

Thus, according to the stirring device with excellent mixing reactivity of the present invention, instead of using the existing stirring blade, it moves across the treated water stored in the stirring vessel structure, and generates a rapid vortex in the treated water, thereby causing the active of the contaminant and the input agent particles. Improving agitation properties by enabling impingement and agglomeration agitation, and at the same time, it is possible to save power than using a stirring blade, and provides an excellent effect that can significantly reduce the operating cost of the equipment.
