Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

The present invention relates to a flock monitoring device of a water treatment facility.

Generally tap water is produced by passing through mixing basin, flocculation basin, sedimentation basin and filter basin.

In the mixed soil, flocculant is provided in the raw water containing a large amount of foreign matter from the water source, and foreign substances are solidified in the form of floc by the flocculant.

The raw water in which the flocs are formed in the mixed paper is provided as a cohesive paper, and the size and the number of the flocs are increased in the cohesive paper.

The raw water is supplied to the sedimentation basin, and the flocs are precipitated in the sedimentation basin. The raw water in which the flocs are precipitated is supplied to the filter paper from the sedimentation basin, and flocs and other foreign matter are completely filtered from the filter paper to produce tap water.

In this water treatment process, it is very important to solidify the foreign substances contained in the raw water into flocs.

In particular, when the amount of coagulant supplied to the raw water is insufficient compared to the foreign substances contained in the raw water, the flocs are not formed smoothly, and the foreign matter is not completely removed from the raw water, so that it is difficult to drink with drinking water.

On the other hand, when the amount of coagulant supplied to the raw water is larger than the amount of the foreign material, the coagulant remains in the raw water and is difficult to drink as drinking water.

Therefore, the number of flocs and the size of the flocs formed in the raw water by the coagulant provided in the raw water are monitored in real time, and the amount of coagulant supplied to the raw water by the monitoring result is feedback-controlled.

As a method for monitoring the number of flocs formed in the raw water, Korean Patent No. 10-0448560 and Floc measurement system of cohesive paper (registered on September 3, 2004) are representative.

In the floc measurement system of the coagulant, a floc characteristic of the coagulant is measured by an image acquisition device fixed to the coagulant to control the coagulant stirring speed and the coagulant input amount.

However, since the flock measuring system of the flocculation paper monitors the flocs from the image capturing device capturing the water surface of the flocculating paper in a state fixed to the flocculating paper, it is difficult to monitor the size and number of flocs according to the depth of the water surface of the flocculating paper

Also, since the flocculation system of the flocculation paper is fixedly arranged, it is difficult to accurately monitor the position of the flocculation paper, for example, the size and number of flocs at the edge of the flocculation paper or the central part of the flocculation paper.

In addition, in the flock measurement system of the cohesive paper, the camera is always disposed at the lower part of the water surface, and moss and the like are easily attached to the lens part of the camera by the raw water, thereby requiring a separate washing pipe or the like for monitoring flocs.

The flock measuring system of the cohesive paper is very difficult to clean the camera completely because it cleans the image stroke device by the flushing pipe disposed below the water surface of the raw water.

Further, the flock measuring system of the cohesive paper can not compare the flock size, the number per unit area of flocs and the volume of the flocs generated per unit time, and accurately calculates the actual size of the flocs, the number per unit area, and the volume of flocs generated per unit time There is no problem.

The second guide rail 210 is coupled to the first drive unit 120 of the first guide unit 210. Accordingly, the second guide rail 210 is moved together with the first guide unit 210.

The second guide rail 210 may be formed of a metal material or a rail.

The second guide rail 210 may be formed perpendicular to the bottom of the cohesive paper 2 with respect to the water surface of the cohesive paper 2. [

In one embodiment of the present invention, a portion of the second guide rail 210 coupled to the first drive unit 120 extends to a portion adjacent the bottom of the cohesive paper 2, Some extend to the upper part of the water surface of the coagulant 2.

The second driving unit 220 is mounted on the second guide rail 210 and the second driving unit 220 allows the camera 300 to be described later to be moved along the second guide rail 210.

The second drive unit 220 includes a screw 224 screwed to the drive block 222 and the drive block 222 and a motor 226 for rotating the screw 224 .

The motor 226 may be fixed to the upper end of the second guide rail 210 disposed on the upper surface of the water surface of the cohesive paper 2 among the second guide rails 210.

The screw 224 is coupled to the motor 226 in a direction parallel to the second guide rail 210, that is, toward the water surface, and the screw 224 extends to the lower portion of the water surface of the cohesive paper 2.

The drive block 222 is coupled to the screw 224 in a screw tightening manner and the drive block 222 is lifted or lowered along the second guide rail 210 as the screw 224 is rotated by the motor 226 Whereby the drive block 222 can be lowered to a position above the surface of the flocculation paper 2 and adjacent to the bottom of the flocculation paper 2.

The camera 300 is mounted on the driving block 222 of the second driving unit 220. In an embodiment of the present invention, a camera 300 can be used that can be photographed even if placed under the water surface of the coagulant 2.

When the camera 300 mounted on the driving block 222 of the second driving unit 220 of the second guide unit 200 is lowered to the lower part of the water surface of the cohesive paper 2 in an embodiment of the present invention, It is possible to accurately monitor the flock state by photographing the number of flocs according to the variation of the depth of the cohesive paper 2, the size of the flocs according to the change of the depth of water, or the volume of the flocs according to changes in the water depth.

On the other hand, while the camera 300 does not photograph the flock of the cohesive paper 2, the camera 300 is disposed on the upper surface of the water by the second guide unit 200, It is possible to prevent the lens of the camera 300 from being seriously contaminated by foreign matter, green algae, flocs, etc. contained in the raw water of the camera 300 for a long time.

Figs. 5 and 6 are sectional views showing a flask volume measuring tank, a camera, a floc volume measuring unit and a floc counting unit.

5 and 6, the fl ow volume measuring water tank 250 is coupled to the second driving block 222 of the second guide unit 200, and thus the fl ow volume measuring water tank 250 is connected to the second guide Unit 200 together.

The floc volume measuring water tank 250 is formed in a very small size as compared with the flocculating paper 2 and the floc volume measuring water tank 250 is formed in the upper portion of the flocculation paper 2 for sampling a part of the floc falling to the bottom of the flocculating paper 2. [ As shown in Fig.

The floc volume measuring water tank 250 may be formed in various three-dimensional shapes having a storage space therein. In one embodiment of the present invention, the flot volume measuring water bath 250 may be formed in a shape similar to a hexahedral shape with, for example, an open top.

The floc volume measuring water bath 250 includes a plurality of sidewalls 252 and a bottom plate 254 that forms the bottom of the sidewalls 252.

One side of the bottom plate 254 of the floc volume measuring water tank 250 is hinged to a lower end of either side wall 252 of the side wall 252 by a hinge pin or a hinge or the like .

That is, the bottom plate 254 of the floc volume measuring water tank 250 has a structure that contacts with the side wall 252 while being rotated with respect to the side wall 252, or is spaced apart from the side wall 252.

The camera 300 is coupled to the inner side of one side wall 252 of the floc volume measuring water bath 250. The camera 300 takes a picture of the flock generated under the water surface of the cohesive paper 2 to produce a digital image or a digital image to calculate the number of flocs, the size of the flocs and the volume of the flocs.

The flock counting unit 330 is coupled to the camera 300 to measure the number of flocks per unit area and the size of each flock generated in the aggregation paper 2 through the digital image or the digital image generated from the camera 300 .

5 and 6, the flock counting unit 330 is disposed in front of the camera 300 and disposed within the shooting range of the camera 300. [

The flock counting unit 330 and the camera 300 are interconnected by a plurality of connecting members 335.

The flock counting unit 330 disposed in front of the camera 300 has a lattice form. For example, the flock counting unit 330 includes a horizontal grid 332 arranged in a horizontal direction and a vertical grid 334 arranged in a vertical direction, and is formed by a horizontal grid 332 and a vertical grid 334 All the spaces are formed with the same lattice area.

When the flocks fall between the flock counting unit 330 and the camera 300 having the same lattice area, the camera 300 is shot together with the flock counting unit 330 and the flock.

Since the lattices of the flock counting unit 330 have the same area, the image taken from the camera 300 is subjected to image processing so that the number of flocks included in each lattice is accurately calculated by considering the coefficients and the area of the lattice .

On the other hand, with the flock counting unit 330 and the camera 300, it is possible to deduce the volume of the flock per unit volume, and it is difficult to calculate the volume of the flock per unit volume accurately.

In order to accurately calculate the volume of the flock per unit volume and use it as data for determining the dosage of the flocculant, a floc volume measuring unit 350 is disposed inside the floc volume measuring water tank 250.

The flock volume measuring unit 350 is disposed within the shooting range of the camera 300. [

The flock volume measurement unit 350 includes a flock volume measurement container 352 and a floc discharge unit 359.

The flock volume measurement container 352 is formed of a transparent material having an open upper portion for accommodating the falling flock. The flock volume measurement container 352 is disposed inside the flock volume measurement water tank 250, A weighing scale for measuring the volume is formed.

The camera 300 uses the timer 400 to take the flock volume measurement container 352 for a specified time or at designated time intervals.

The volume per unit time of the floc stored in the floc volume measurement container 352 photographed from the camera 300 can be calculated through a scale formed in the floc volume measurement container 352 through an image processing process.

The floc discharge unit 359 discharges flocs stored in the floc volume measurement container 352 after the volume of the floc per unit time is measured.

The floc discharge unit 359, for example, rotates the floc volume measurement vessel 352 in the gravitational direction to discharge the floc stored in the floc volume measurement vessel 352.

The floc discharge unit 359 includes a rotation shaft 353, a waterproof motor 354 and a bracket 355.

The rotary shaft 353 serves to rotate the flock volume measurement container 352. One end of the rotary shaft 353 is fixed to the outer surface of the flock volume measurement container 352, Is projected outside the side wall 252 through the side wall 252 of the floc volume measuring water tank 250.

The waterproof motor 354 is disposed at a position opposite to the other end of the rotation shaft 353 passing through the side wall 252 and the shaft of the waterproof motor 354 is engaged with the rotation shaft 353.

The rotation shaft 353 is rotated by the rotation of the shaft of the waterproof motor 354 and the flock volume measurement container 352 is rotated by the rotation of the rotation shaft 353. [ A water reducer or the like may be disposed inside the waterproof motor 354.

Although it is shown and described that the flocking unit 359 is rotated using the waterproof motor 354 in one embodiment of the present invention, it is also possible to use various mechanism members for converting the linear motion into the rotational motion .

The bracket 355 serves to fix the waterproof motor 354 disposed on the outside of the side wall 252 to the side wall 252.

One end of the bracket 355 is fixed to the outer surface of the side wall 252 and the other end of the bracket 355 is coupled to the waterproof motor 354. [

On the other hand, the floc discharging unit 359 is provided on the floor (bottom) for removing the flocs accumulated on the bottom plate 254 by rotating the bottom plate 254 of the floc volume measuring water tank 250 together when the floc volume measuring container 352 is rotated And a plate rotating unit 356.

The bottom plate turning unit 356 interlocks the rotation shaft 356 and the hinge shaft 246 of the bottom plate 245 so that the bottom plate 245 rotates in the same direction when the rotation shaft 356 is rotated.

The bottom plate turning unit 356 may include a drive pulley coupled to the rotation shaft 356, a driven pulley coupled to the hinge shaft 246 of the bottom plate 245, and a belt or chain connecting the drive pulley and the driven pulley. have.

7 is a cross-sectional view illustrating operation of a bottom plate rotating unit according to an embodiment of the present invention.

6 and 7, a bottom plate 254 coupled to the side wall 252 is also rotated when the flock volume measurement vessel 252 is rotated by the flock discharge unit 359, 352 are discharged to the outside from the flock volume measurement container 352. The flock discharged from the flock volume measurement container 352 is introduced into the floc volume measurement water tank 250 by opening of the bottom plate 254 And is provided to the bottom surface of the agglomerated paper 2 without being accumulated.
