DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water quality improving agent spraying boat apparatus, and more particularly to a water quality improving agent spraying boat apparatus capable of spraying an improving agent near a quay or the like.

[0002]

2. Description of the Related Art In recent years, the sea and rivers are polluted with the inflow of domestic wastewater and industrial wastewater, generating hydrogen sulfide, blue tide, red tide, and the like, and sludge is deposited on the bottom.

[0003] In order to improve the water quality and sediment of such seas and rivers, improvers such as lime have been conventionally sprayed.

[0004]

In order to improve the water quality and sediment as described above, it is generally necessary to spray 400 g of an improving agent such as lime per 1 m ² . Improving agents such as lime are sprayed by hand, and powders are scattered by such an improving method, which is not only harmful to the human body, but also cannot be sprayed at a uniform concentration continuously over a wide area. In addition, there were drawbacks in the vicinity of the quay, such as the inability of the barbed material and the stake to disperse and prevent spraying.

The present invention has been made to eliminate the above disadvantages.

[0006]

SUMMARY OF THE INVENTION A water quality improver sprayer apparatus according to the present invention forms a slurry by stirring a water quality improver sprayer body and a predetermined amount of powder of the improver with a predetermined amount of water. Means, a scatter rod of the slurry, a scatter nozzle provided at a lower end of the scatter rod, a guide turret supporting the scatter rod vertically movable outside one end of the scatter boat body, and a guide turret relative to the guide turret. to a spraying rod vertical movement means for allowing vertical movement of the spraying rod, Ri more a guide tower moving means for allowing movement of the guide tower in a direction projecting from the spraying vessel body, said spraying nozzle, medium

Embodiments of the present invention will be described below with reference to the drawings.

1 to 3 show a water quality improver spraying apparatus according to the present invention, wherein 1 is a workboat, 2 is a hopper storage tank for placing a powdery improver arranged on the barge 1, and 3 is a hopper storage tank. Hopper,
Reference numeral 4 denotes an improver measuring device for measuring the improver as it passes from the hopper 3, 5 denotes a screw conveyor, 6 denotes a slurry stirring tank, and 7 denotes a high-pressure spray pump.

In the present invention, a predetermined amount of powder of water quality and bottom sediment improver such as lime is continuously taken out from a hopper storage tank 2 on a workboat 1 via a hopper 3 and a improver measuring device 4, and a screw is removed. The slurry is continuously introduced into the slurry stirring tank 6 via the conveyor 5 and stirred together with a predetermined amount of water, for example, at a ratio of the improver 1 to water 10.

A telescopic base 8 is attached to one end of the work barge 1 and extends horizontally beyond the end of the barge.
An improving agent spraying guide tower 10 is attached to the tip of the base 8 via an arm 9, and the base 8 can be extended and contracted by an extension means 11.

An improving agent spraying rod 12 is attached to the guide tower 10 via a winch wire 13 so as to be movable up and down.
4 and the spray nozzle device 14 and the stirring tank 6
The spaces are connected by an improver spray hose 15 so that the slurry can be pumped to the spray nozzle device 14 by the high-pressure spray pump 7.

As shown in FIG. 3, the spray nozzle device 14 has a common nozzle mounting triangular base 16 extending in the horizontal direction and, for example, six 90 ° to 120 ° wide-angle spray nozzles disposed at the lower end of the base 16. The nozzle 17 is used.

As shown in FIG. 4, the wide-angle spray nozzle 17 has a nozzle body 18, a center hole 19, and a central hole 19.
And a conical hole 21 that gradually widens radially outward toward the opening 20. By changing the pressure of the spray to be sprayed, the spray angle is set to, for example, 90 ° to 120 °.
Can be changed to

Since the water quality improving agent spraying boat apparatus of the present invention has the above-described structure, the rod 12 is usually lowered into the water through the winch wire 13 to convert the water quality such as lime and the bottom quality improving agent slurry into sludge. After dredging, for example, a maximum pressure of 20 kg / cm ^{2 at a} position 1 m above the water bottom from the nozzle 17
Sprinkle with.

In the case of spraying near the quay, the guide tower 10 is projected horizontally by the expansion and contraction means 11 and only the spray nozzle device 14 is positioned near the quay to perform spraying.

In this case, if the spray angle is increased by changing the spray pressure, the spray can be sprayed closer to the quay.

[0018]

According to the water quality improver spraying apparatus of the present invention as described above, the improver slurry can be obtained very easily and continuously, and it can be continuously dispersed in a wide area of water. Can be sprayed at a uniform concentration and the guide tower 10
The spraying of the slurry in the horizontal direction makes it possible to spray the improver even in places where there is an obstacle such as near the quay and the workboat 1 cannot be approached. When sprayed on, it is possible to easily suppress the floating mud generated after sludge dredging, and at this time, there is a great advantage that the spray angle can be arbitrarily changed as required.
