Description

Vehicle for supplying cooling water to grooving machine

The present invention relates to a cooling water supply vehicle for a grooving operation, and more particularly, to solidify the slurry in the form of slurry generated during the grooving operation on the pavement surface, thereby grooving the separation liquid. The present invention relates to a cooling water supply vehicle for grooving operations that can easily collect sludge and recycle it with the cooling water of the machine.

In general, the grooving method is a surface treatment method for forming a groove on a pavement surface such as asphalt or cement at regular intervals. The grooving method is carried out to flatten the uneven pavement surface, or to prevent slipping due to water film development and drainage, to prevent freezing, to improve driving safety, and to prevent noise.

A grooving machine is used for this grooving method. The grooving machine is provided with a plurality of cutting edges for digging grooves in the transverse or longitudinal direction on the pavement surface, and can be classified into wet (water cooling) and dry (air cooling) according to the cooling method of the cutting edge.

The wet grooving machine has the advantage of fast working speed because it cools the cutting edge with coolant, which is why it is widely used for grooving. The amount of coolant used in a wet grooving machine usually consumes about 15 tonnes based on 5 hours of work. The grooving operation is carried out in such a way that a cooling water supply vehicle having a large water tank (usually 3 to 8 tons) moves with the grooving machine and supplies the cooling water.

[Operation of the present invention]

Hereinafter, with reference to the accompanying drawings will be described the operation of the cooling water supply vehicle for grooving operation according to the present invention.

Cooling water supply vehicle 100 according to the present invention is to perform a grooving operation with the grooving machine 200 as shown in FIG. That is, the grooving machine 200 forms grooves having a predetermined interval on the pavement surface by using the cutting blade 210. In addition, the cooling water supply vehicle 100 may supply the cooling water to the grooving machine 200 while following the grooving machine 200 at a speed of less than 4 km / h. At this time, the dust generated by the cutting blade 210 is mixed in the cooling water, thereby producing a slurry to flow on the pavement surface. Such a slurry is sucked by the vacuum pump 220 and the suction hose 230 provided in the grooving machine 200, and is transferred to the cooling water supply vehicle 100.

The slurry transferred from the grooving machine 200 is transferred to the solid-liquid separator 130 through a hose or pipe 124. Specifically, it is temporarily stored in the slurry reservoir 122 provided in front of the vehicle 100, and is transferred to the stirring tank 126 by the slurry transfer pump 120. At this time, the slurry reservoir 122 accommodates a relatively large amount of slurry to smooth the pumping action of the slurry transfer pump 120. In addition, the slurry temporarily stored in the stirring tank 126 is agitated to a constant concentration by an agitator (not shown) and transferred to the solid-liquid separator 130. At this time, it is possible to prevent the overload and failure of the solid-liquid separator 130 by the stirring action of the stirring tank 126.

The solid-liquid separator 130 separates the transferred slurry into a separation liquid (water) and solid sludge. Solid-liquid separator 130 according to the present invention is a centrifugal separator as shown in Figure 3, the rotating cylinder 132 is rotated at a high speed at a speed of 4000 ~ 5000rpm, the transfer screw 134 is inside the rotating cylinder 132 Rotate at a speed smaller than the rotating cylinder (132). Then, the slurry is introduced into the transfer screw 134 as shown in FIG. The injected slurry is discharged from the slurry discharge hole 135 of the transfer screw 134 and flows into the rotating cylinder 132. The slurry introduced into the rotary cylinder 132 is moved to the conical inclined portion 132a of the rotary cylinder 132 by the transfer screw 134. At this time, the slurry is precipitated solid sludge with a high specific gravity by the centrifugal force by the rotating cylinder 132 is rotated at high speed, the sludge is dewatered from the conical inclined portion (132a) is discharged through the sludge discharge hole (133a). Then, the separation liquid is discharged to the separation liquid discharge hole 133b formed at the left end of the rotating cylinder 132 through the spiral channel (not shown) of the transfer screw 134. The discharged sludge and the separation liquid are guided by the partitions 138a and 138b formed inside the casing 137, respectively, and are respectively dropped in the direction of the arrow shown in FIG. 3 to separate the separation liquid reservoir 160 and the sludge storage part 160. Will be moved to.

Separation liquid stored in the separation liquid reservoir 160 is transferred to the water tank 110 by the separation liquid transfer pump 150 shown in FIG. At this time, when the separation liquid is stored in the separation liquid reservoir 140 in a predetermined amount or more, the level control device (not shown) is to operate the transfer pump 150 automatically.

The separation liquid stored in the water tank 110 is re-supplied to the grooving machine 200 through the hose or pipe 113 by the coolant transfer pump 112 as shown in Figs. ) Is recycled into the coolant.

The cooling water supply vehicle 100 according to the present embodiment has a capacity of about 6 tons of the water tank 110. When the cooling water supply vehicle 100 is put into the grooving operation and consumes 6 tons of cooling water, the amount of the separation liquid recycled by the solid-liquid separator 130 is about 3.6 tons. This is because not only the slurry produced during the grooving operation is not completely collected by the slurry transfer pump 120 but also the slurry is not completely dehydrated by the solid-liquid separator 130. That is, about 2.4 tons of cooling water is consumed in 6 tons of cooling water. Therefore, by recycling the 3.6 tons of the separation liquid to the cooling water, the amount of cooling water required for the grooving operation can be greatly saved. This can reduce the interruption of the grooving operation to recharge the cooling water in the cooling water supply vehicle 100, which brings about the efficiency of the grooving operation.

On the other hand, the sludge falling from the solid-liquid separator 130 to the sludge storage unit 160 is collected through the following process. At this time, the sludge housing 160 is in a state where the sack holder 161 protrudes toward the rear side of the vehicle 100 as shown in FIGS. 1 and 2.

First, the sludge falling from the solid-liquid separator 130 is dropped to the front side of the conveying belt 162 via the sludge guide cylinder 167 as shown in Figure 7b. Then, it is conveyed to the rear side by the conveying belt 162, and is dropped to the sack (not shown) of the cradle 161 is received. And, when the sludge is filled in the sack (not shown), the worker can collect it, and by placing a new sack on the cradle 161, the sludge can be continuously collected.

As described above, the cooling water supply vehicle 100 according to the present invention has an effect of widening the working radius of the worker as the sack holder 161 of the sludge storage unit 160 protrudes a predetermined distance to the rear of the vehicle 100 during the grooving operation. Bring it. Through this, the sludge collection operation can be made more efficient, and the labor cost can be reduced significantly by reducing the number of workers.

On the other hand, when the grooving operation is completed, the cooling water supply vehicle 100 shortens the hydraulic cylinder 166 as shown in FIG. 7A to draw the transfer belt 162 and the stool holder 161 to the front side of the vehicle and operate the cooling water supply vehicle 100. Done.
