Description

Friction-reducing rotary nozzle body {ROTARY NOZZLE APPARATUS FOR REDUCING FRICTION}

The present invention relates to a friction reducing rotary nozzle body. More particularly, the present invention relates to a friction reducing rotary nozzle body which sprays snow melt while rotating to enable snow melting over a wider area.

Generally, when the snow falls in winter and the road surface freezes, vehicle accidents and pedestrian traffic accidents may occur. Especially, in the case of roads with sloped mountainous terrain, the melting speed of snow due to shade is very slow compared to general roads. Therefore, if the snow accumulated on the road is not cleared quickly, the road freezes and traffic accidents occur frequently.

Therefore, in order to prevent freezing of the road, a method of spraying sand or calcium chloride on the road by a manpower is mainly used.

However, in order to continue to use the above-described conventional method, there is a problem in that a huge road snow removal cost is repeatedly spent every year.

In order to solve such a problem, a molten liquid injector has been disclosed to spray snow melt on a road surface by continuously forward and reverse rotation by using an inflow pressure difference of snow melt flowing into the prior art.

However, in the above-described conventional technology, when the injection pressure is variable due to the structure of forward and reverse rotation using the pressure difference, the speed of the forward and reverse rotation is also variable, so that precise control of the forward and reverse rotation is impossible, so that the snow melting efficiency is lowered, and the lower outer peripheral surface of the injection nozzle part is also reduced. Since only one rubber packing structure is installed in the structure, when the injection pressure of the snow melt is high, there is a problem that can not withstand the high pressure and the snow melt flows out.

In addition, due to the high frictional resistance between the parts in the forward and reverse rotation, as the damage between the parts deepens over time, as a result, the durability is very low and the long-term use is difficult, so the maintenance management cost such as frequent replacement of parts is very high.

In addition, when snow melt or salt water is introduced into the gap between the reverse rotation part and the injection nozzle part, the frictional resistance against the reverse rotation increases further, thereby increasing the frequency of failure, unbalanced the injection direction of the snow melt, and increasing noise. There is a problem.
