Description

  The present invention relates to a snow melting agent composed of charcoal powder and sand.

  It is used as a snow melting agent to promote the melting of snow early by spraying charcoal crushed material on the snow cover of golf courses and farmland.

There is a snow melting agent obtained by stirring a pulverized carbonaceous material and water.
Patent Publication 2001-181608

  On roads, a snow melting method using calcium chloride is common, but it causes salt damage to vehicles and the natural environment.

  When charcoal powder is sprayed as a snow melting agent, the amount of loss due to scattering is very large and the spraying efficiency is inferior. On roads, there is a risk of pedestrians and vehicle slipping when the water freezes after melting snow. there were.

  The present invention is intended to solve the problem of the snow melting agent using such charcoal powder, and while improving the spraying efficiency, pedestrians and vehicles against freezing after spraying on roads, golf courses, and farmland. It aims at providing the snow melting agent which united the function which can prevent the slip of snow.

Means to solve the problem

  In order to achieve the above object, the present invention provides a charcoal powder obtained by crushing charcoal, bamboo charcoal, or rice bran charcoal into a powdery particle having a particle diameter of 5 mm or less, and river sand, mountain sand, or rock. It is characterized by being a snow melting agent that can be dispersed without scattering the charcoal powder by agitation with the sand and adhering the charcoal powder to the surface of the sand. A snow melting agent that can prevent slipping by sand.

The invention's effect

  The snow melting agent of this invention can provide the snow melting agent which suppressed the loss by scattering of charcoal powder by making charcoal powder adhere to the surface of sand, and raised the efficiency to the spraying area with respect to the usage-amount of charcoal powder.

In addition to the above-mentioned spraying effect as a snow melting agent, it is possible to prevent pedestrians and vehicles from slipping due to freezing after snow melting with sand.

  The snow melting agent of the present invention is used to prevent snow melting and slipping by remaining in the rainy season, in contrast to calcium snow melting agent that melts and flows out due to its own snow melting effect on sloped roads such as mountainous areas. It is effective.

  When the snow-melting agent of the present invention is sprayed on the road, the snow-melting agent remaining on the road surface after snow melting flows out together with water due to rain and leads to river purification.

  By using the snow melting agent of the present invention in combination with a snow melting agent based on calcium chloride, neutralization can be promoted with respect to acidic calcium chloride by the effect of alkaline charcoal powder, and a snow melting method considering the natural environment can be provided.

  When the snow melting agent of the present invention is sprayed on a golf course or farmland, it exerts an effect on germicidal effects of germs and rooting of turf or crops after snow melting.

BEST MODE FOR CARRYING OUT THE INVENTION

  Hereinafter, embodiments of the present invention will be described with reference to FIGS.

  A specific example of processing charcoal, bamboo charcoal, or rice bran charcoal into charcoal powder that has been processed into a powder having a particle size of 5 mm or less is as follows. After pulverization, the air is blown to the primary hopper 2. Charcoal particles of 5 mm or less are accumulated in the containers of the primary hoppers 2 to 10, and the carbon particles that cannot pass through the sieve of 8 are sent to the container of 9. Among the carbon powder, fine particles 11 are sent to the secondary hopper together with air.

  Specific examples of stirring charcoal, bamboo charcoal, or rice husk charcoal 10 in a powdery form with a particle size of 5 mm or less, and sand with a particle size of 5 mm or less obtained by crushing river sand, mountain sand and rocks are shown in the figure. As in 2, sand and charcoal powder are added to the concrete mixer 4 and stirred.

  The mixing ratio of stirring can be adjusted according to the purpose of use, with carbon powder 0.2 being standard for sand 1 in weight ratio. During the agitation, the mixture is agitated while mixing water to such an extent that no soot is generated from the secondary hopper exhaust port 7, and a mixture of charcoal powder and sand is produced. This is sent to the secondary hopper 5 by a belt conveyor.

  In the secondary hopper 3, fine carbon powder further adheres to the agitated carbon powder and sand mixture, and the snow melting agent 12 which is the product of the present invention is stored here. In addition to the above, the sand and charcoal powder may be fused by stirring in water and drying.

From the secondary hopper 3, a snow melting agent is filled in a container that can be hermetically packaged, and hermetically sealed with a welding sealer.

  As for the spraying method, as a snow melting material, it can be opened and put into a conventional salt-car spraying vehicle, and machine spraying can be performed.

  Further, it can be opened and put into an agricultural dusting machine and sprayed by a machine, and a method by handing may be used.

As a snow melting agent, 1.1 kg per 10 m ^{2 of the} present invention was manually spread on an asphalt pavement where the weather conditions were 7:00 am, the temperature was −3 ° C., the weather was clear, and the snow was 15 cm. The ratio of sand and charcoal powder at this time is 0.1 charcoal powder with respect to sand 1 in weight ratio. It can be easily sprayed without generating dust, and the spraying amount can be confirmed in black on the snow surface.

  At 12:00 noon and at a temperature of 4 ° C, the melting of the snow at the sprayed place was completed, and sand and charcoal powder were confirmed on the pavement surface where moisture remained. The unsprayed area leaves about 12 cm of snow, and the charcoal powder that has flowed out adheres to the remaining snow at the surrounding spreading boundary, and further melts snow to the surroundings. The next day at 7:00 am and at a temperature of −4 ° C., the melted water was frozen, but it was difficult to slip due to the sand effect.

  At present, snow melting agents mainly made of calcium chloride are mainly used on roads, but on steep roads such as mountainous areas, the water flows out with the water from which calcium chloride has melted, and then the temperature decreases. Because it freezes, sand and charcoal powder remain on the road until the rain in the present invention, so that the slip prevention effect is exerted even on a sherbet-like snowy road or icing, and traffic safety is improved. Is.

  As a snow melting agent, it is easy to spread charcoal powder.

  In a particularly soft ground such as a golf course or farmland, the snow melting agent of the present invention is repeatedly sprayed, whereby the soil is tightened by the effect of sand, and the rooting of turf and crops is promoted by the effect of charcoal powder.
