Abstract

PURPOSE:To continuously treat melted snow and water by a method in which a steam jet nozzle is set on the lower part of a snow-thawing plate and a drain pan to trap melted snow water is provided on the back side of the bottom of a shovel to make up a snow-thawing section, and the melted snow water is partly recovered by a drain pump for reuse. CONSTITUTION:A snow-thawing plate 2 to introduce snow to a snow-thawing section is provided to a shovel 1, a steam jet nozzle 3 is provided to the lower part of the plate 2, and a drain pan 4 to trap melted snow water is provided to the back side of the bottom of the shovel 1. Melted snow water is recovered by a drain pump 5 and partly reused for boiler and the other is discharged to drainage. A high-place steam snow-thawing device is made up of a steam nozzle (a), a drain hopper (b), a steam pipe (c), a control valve (d), a steam hose (e), and a drain hose (f), which collect melted snow and ice waters. Snow and ice in every state can thus be easily melted, treated, and reused for water supply for steam production.

Description

DETAILED DESCRIPTION OF THE INVENTION (1) Industrial Application Field The present invention is intended to rationally solve traffic obstructions caused by snowfall in snowy regions and lightning extinguishing at high places such as roofs of houses. The snow and water at the point where this device passes is melted by steam, turning into snowmelt water with a volume of just a few minutes, making it easier to handle. After collecting this, some of it is reused for water supply to the boiler. , the remaining water is drained into the drainage channel, so unlike traditional snow removal methods, there is no problem with snow that accumulates on the sides and surrounding areas after snow removal, and it is a reasonable method of extinguishing lightning that does not stain the road surface with water. there is.

(b) Conventional technology Snow removal tools that have been commonly used include small-scale manual snow removal methods such as shovels and snow dumpers, snow removal methods that melt snow by draining underground water, and snow removal methods that blow away snow using centrifugal force using motorized snow removal tools. Large-scale public snow removal methods involve using rogues, shovels, etc. to collect snow and dumping it out, which often causes problems with groundwater shortages and lack of places to dispose of snow.

(c) Problems to be solved.

Conventional snow removal methods simply move the snow, and this moved snow also causes obstacles and requires removal.
It required a lot of effort and expense. In order to solve this problem, the snow removal site should be free of snow and water stains, and there should be no piles of snow left in the surrounding area.

B) Means for Solving the Problem The present invention uses a steam boiler as a heat source for snow melting, which can stably transmit high temperature even in severe cold, and can supply the pressure and steam amount corresponding to the amount of snow in each situation. The snow or ice at the lightning extinguishing area is safely and reliably melted in the snow melting section, and the equipment's drain pump collects snow melt water and drains it to the drainage channel for reuse and recovery. This system is characterized by continuous treatment of snowmelt water.

(e) Effects and Examples Next, the method and product of the present invention will be explained by giving examples.

First example Maximum evaporation amount as a heat source: 52 kg/Hr.

Calorific value 27,991kcal/Hr, maximum pressure 3.0k
As a result of a snow melting experiment using this device using a once-through steam boiler with a specification of ``g/cm'', the snowfall amount was 21.8 m/hr when the snow was melted at a depth of 30 cm, and the snow was melted at a depth of 70 cm during snow melting. It can be consumed, and its melting snow volume is 4,578
m3/Hr, and the amount of snowmelt water is 704Q/Hr.
Met. Although the results may differ depending on the snow quality, the results of the experiment are as above.

Of the 704Q/Hr of snowmelt water, 52Q/Hr is reused for boiler feed water, and the remaining 65212Q/Hr is
Drained with a hose.

The fuel cost in this case is 5Q/Hr for kerosene, which is approximately 225
It was yen. Snow melting fuel cost per 1 m' is 225/45
It is economical at 78 = 49 yen, and is an excellent lightning extinguishing method considering the cost and cost of removing surrounding snowy mountains caused by snow removal.

Example 2: As shown in Figure 4, a snow melting water tray and a steam injection nozzle are efficiently installed at the end of a long steam pipe, and steam is sent through a steam hose through a control valve attached to a handle to remove snow from high places and the roof. It safely melts snow and ice from icicles, etc., and can achieve its purpose without having to climb to dangerous heights due to snow.

(f) Effects of the Invention Next, the effects of the steam extinguishing device of the present invention will be described. It melts snow and water in all snow conditions, reduces the volume as water, makes it easier to treat, and supplies water for steam generation. This steam lightning extinguishing device is suitable for the coldest and most snowy regions, as it can be reused as a dehydrator and completely removes snow, even leaving traces of snow melted by the device.
