Description

攪拌式融雪装置Stirring snow melting device
　本発明は、雪を攪拌しながら融解する攪拌式融雪装置に関するものである。 The present invention relates to a stirring-type snow melting device that melts snow while stirring.
　従来、北海道等の降雪量の多い地域では、道路や市街地に降り積もった雪をロータリー除雪車等によって除雪し、その雪をダンプカー等に積んで郊外に用意された排雪地や河川等に投棄するのが一般的である。しかし、上記のような除雪作業には、排雪地の確保や労働力をはじめとして膨大な費用と人手が必要となり、さらに深夜作業のため騒音や交通渋滞を発生させるという問題もある。 Conventionally, in areas such as Hokkaido where there is a lot of snowfall, snow that has accumulated on roads and urban areas is removed with a rotary snowplow, etc., and the snow is dumped onto dump trucks, etc., and dumped in snowy areas or rivers prepared in the suburbs. It is common. However, the above snow removal work requires a huge amount of money and manpower, such as securing a snow discharge area and labor, and there is also a problem that noise and traffic congestion occur due to late night work.
　そこで、従来、排雪ではなく、除雪した雪を融かしてしまうための融雪装置が提案されている。例えば、特開２０１０－１０１０３１号公報には、平面状に配設された放熱管にボイラーで加熱した熱媒体を循環させ、該放熱管を加熱することによって融雪を行う融雪装置が開示されている（特許文献１）。 Therefore, conventionally, there has been proposed a snow melting device for melting snow removed instead of snow removal. For example, Japanese Patent Application Laid-Open No. 2010-101031 discloses a snow melting apparatus that circulates a heat medium heated by a boiler through a flatly arranged heat radiating pipe and heats the heat radiating pipe to melt snow. (Patent Document 1).
　また、特開２００３－１４７７４１号公報には、融雪処理を行う融雪槽と、温水を供給する温水シャワーと、投入された雪を攪拌する攪拌機構と、水を貯留する貯留槽と、貯留槽内部の水位を検出する水位センサと、貯留槽内の水を加熱して循環させる循環機構と、水位センサの検出結果に基づき水供給源の制御を行う制御部とを有する融雪装置が開示されている（特許文献２）。 Japanese Patent Application Laid-Open No. 2003-147741 discloses a snow melting tank that performs a snow melting process, a hot water shower that supplies hot water, a stirring mechanism that stirs the introduced snow, a storage tank that stores water, A snow melting device having a water level sensor for detecting the water level of the water, a circulation mechanism for heating and circulating the water in the storage tank, and a control unit for controlling the water supply source based on the detection result of the water level sensor is disclosed. (Patent Document 2).

　しかしながら、特許文献１に記載された発明を含め、従来の放熱管を用いた融雪装置は、地下に埋設したり、屋根上に配設して使用することが多い。このため、設置工事に多大な費用とコストがかかるという問題がある。また、固定設置型であるため、道路等で除雪した雪を融雪するには、別途、当該融雪装置まで運搬しなければならず効率が悪い。 However, including the invention described in Patent Document 1, a conventional snow melting device using a heat radiating tube is often used underground or disposed on a roof. For this reason, there is a problem that the installation work is very expensive and expensive. Moreover, since it is a fixed installation type, in order to melt the snow removed from the road or the like, it must be transported separately to the snow melting device, which is inefficient.
　また、特許文献２のように、車載可能な融雪装置も存在するが、攪拌機構が一本の回転軸で構成されている。このため、投入された雪が回転軸や攪拌羽根に付着して肥大化し、攪拌機能が低下してしまうおそれがある。この場合、融雪効率が低下することはもとより、回転軸の駆動源に多大な負荷がかかり、故障してしまうおそれもある。 Also, as in Patent Document 2, there is a snow melting device that can be mounted on a vehicle, but the stirring mechanism is composed of a single rotating shaft. For this reason, the thrown-in snow adheres to a rotating shaft or a stirring blade, and there exists a possibility that the stirring function may fall. In this case, not only the snow melting efficiency is lowered, but also a great load is applied to the drive source of the rotating shaft, and there is a risk of failure.
　本発明は、このような問題点を解決するためになされたものであって、コンパクトに構成されて移動可能であり、攪拌用の回転軸に付着する雪が肥大化するのを防止し、融雪効率を向上することができる攪拌式融雪装置を提供することを目的としている。 The present invention has been made to solve such problems, and is configured to be compact and movable, and prevents snow adhering to the rotating shaft for stirring from being enlarged, snow melting efficiency.

A stirring blade group consisting of a plurality of blades protruding along, a rotation driving means for rotationally driving the rotary shafts, a steam supply means for supplying steam to the snow melting tank, and / or the snow melting tank.

And is inclined in a direction to move snow to a substantially central position of the rotating shaft, and the high-pressure water injection means injects high-pressure water to a substantially central position of the rotating shaft.

It may be a configuration.
　また、本実施形態では、融雪水を循環させて再利用するとともに、余分な融雪水は排水しているが、この構成に限定されるものではない。例えば、融雪槽２の側面に開口を形成し、余分な水をオーバーフローさせるようにしてもよい。 Further, in this embodiment, the snowmelt water is circulated and reused, and the excess snowmelt water is drained. However, the present invention is not limited to this configuration. For example, an opening may be formed on the side surface of the snow melting tank 2 so that excess water overflows.
　つぎに、以上の構成を備えた本実施形態の攪拌式融雪装置１による作用について説明する。 Next, the operation of the stirring snow melting device 1 of the present embodiment having the above configuration will be described.
　本実施形態の攪拌式融雪装置１を用いて雪を融かす場合、まず、吊りフック２１，２１にワイヤーを通して重機等で持ち上げ、トラック等に搭載する。これにより、攪拌式融雪装置１を所望の場所に移動させて融雪作業が可能となり、雪を運搬する必要がなくなる。 In the case of melting snow using the agitation type snow melting device 1 of the present embodiment, first, the suspension hooks 21 and 21 are lifted with heavy machinery through wires and mounted on a truck or the like. As a result, the agitation-type snow melting apparatus 1 can be moved to a desired location to perform snow melting work, and it is not necessary to carry snow.
　つぎに、融雪槽２内に所定の水位まで水を貯留させた後、ホイールローダー等で雪投入用傾斜板８上に雪を投入する。このとき、本実施形態では、攪拌式融雪装置１が、シンプルでコンパクトに構成されているため、全高が低く抑えられている。このため、雪を投入する際の労力が軽減されるとともに、作業時間が短縮化する。 Next, after water is stored in the snow melting tank 2 to a predetermined water level, snow is thrown onto the snow throwing inclined plate 8 with a wheel loader or the like. At this time, in this embodiment, since the stirring type snow melting apparatus 1 is comprised simply and compactly, the total height is restrained low. For this reason, the labor at the time of throwing snow is reduced, and the working time is shortened.
　つづいて、雪投入用傾斜板８上に投入された雪は、滑流手段９によって上方から散水される水によって、雪投入用傾斜板８に沿って徐々に回転軸３側へと滑りながら流れ落ちる。これにより、回転軸３および攪拌羽根群４上に直接雪を投入する場合と比較して、融雪槽２内に貯留されている水を雪が一気に吸収し固まってしまうのを防止する。 Subsequently, the snow thrown onto the snow throwing inclined plate 8 flows down while gradually sliding toward the rotary shaft 3 along the snow throwing inclined plate 8 by water sprayed from above by the sliding means 9. . Thereby, compared with the case where snow is directly put on the rotating shaft 3 and the stirring blade group 4, the water stored in the snow melting tank 2 is prevented from being absorbed at once and solidified.
　つぎに、各回転軸３に設けられた攪拌羽根群４が、回転駆動手段５によって回転駆動され、投入された雪を破砕しながら攪拌する。このとき、融雪槽２内では、蒸気供給手段６から供給された高圧蒸気の凝縮伝熱により、蒸気中の潜熱が一瞬で放出されるため、短時間で雪が融解する。また、本実施形態では、水面下に配置された蒸気供給手段６が、蒸気の噴射音を低減するとともに、蒸気の潜熱を大気中に放出してしまうことがない。 Next, the stirring blade group 4 provided on each rotating shaft 3 is rotationally driven by the rotational driving means 5 and agitates while crushing the introduced snow. At this time, in the snow melting tank 2, the latent heat in the steam is released instantly due to the condensation heat transfer of the high-pressure steam supplied from the steam supply means 6, so that the snow melts in a short time. Further, in the present embodiment, the steam supply means 6 disposed below the water surface reduces the steam injection sound and does not release the latent heat of the steam into the atmosphere.
　また、本実施形態では、各羽根４１の先端が隣り合う回転軸３の近傍まで延設されている攪拌羽根群４同士が、互いに羽根４１と羽根４１との隙間を通過し、隣り合う回転軸３に付着した雪を掻き落とす。これにより、各回転軸３に付着する雪が肥大化するのを防止し、融雪効率の低下やギアモーター５１への過負荷を防止する。 Further, in the present embodiment, the stirring blade groups 4 in which the tips of the blades 41 extend to the vicinity of the adjacent rotation shafts 3 pass through the gap between the blades 41 and the blades 41 and are adjacent to each other. Scrap off the snow adhering to 3. As a result, the snow adhering to each rotating shaft 3 is prevented from being enlarged, and a decrease in snow melting efficiency and an overload to the gear motor 51 are prevented.
　さらに、本実施形態では、攪拌羽根群４の各羽根４１が、投入された雪を回転軸３の略中央位置に移動させるとともに、その移動された雪に対し、高圧水噴射手段７が高圧の水を噴射する。これにより、噴射する水の温度が低くても、水の衝撃で雪が破砕されながら融解する。また、本実施形態では、高圧水の噴射範囲が回転軸３の略中央位置に絞られるため、高圧水ポンプ７２のポンプサイズや消費電力量が低減される。 Further, in the present embodiment, each blade 41 of the stirring blade group 4 moves the introduced snow to a substantially central position of the rotating shaft 3, and the high-pressure water injection means 7 has a high pressure against the moved snow. Spray water. Thereby, even if the temperature of the water to be sprayed is low, the snow melts while being crushed by the impact of the water. Moreover, in this embodiment, since the injection range of high pressure water is restrict | squeezed to the approximate center position of the rotating shaft 3, the pump size and power consumption of the high pressure water pump 72 are reduced.
　融雪槽２内では、循環手段１０および排水手段１１が、融雪槽２内に貯留される融雪水を所定の水位に調整する。このため、水位が高くなり過ぎて、攪拌羽根群４が水没してしまうことがない。このため、攪拌羽根群４による雪の破砕作用が低下するのを防止し、一定の融雪効率を維持する。また、回転軸３を回転させる負荷を抑えることができる。 In the snowmelt tank 2, the circulation means 10 and the drain means 11 adjust the snowmelt water stored in the snowmelt tank 2 to a predetermined water level. For this reason, the water level does not become too high and the stirring blade group 4 is not submerged. For this reason, it prevents that the crushing action of the snow by the stirring blade group 4 falls, and maintains constant snow melting efficiency. Moreover, the load which rotates the rotating shaft 3 can be suppressed.
　また、循環手段１０は、融雪水に含まれる異物等をストレーナ１０２で濾過した後、蒸気ボイラ６２、高圧水ポンプ７２および散水ポンプ９２へ循環させる。このため、水道施設のない場所等でも使用することができ、ランニングコストも低減される。 Further, the circulation means 10 circulates to the steam boiler 62, the high-pressure water pump 72, and the watering pump 92 after filtering foreign matters contained in the melted snow water with the strainer 102. For this reason, it can be used in places where there is no water supply facility, and the running cost is also reduced.
　また、本実施形態では、回転駆動手段５が、各回転軸３の回転方向をランダムに切換制御する。このため、大きい雪塊が投入された場合でも、正逆方向に回転する攪拌羽根群４が、雪塊に対して多方向から衝突し、効果的に破砕する。 Further, in the present embodiment, the rotation drive means 5 performs switching control of the rotation direction of each rotation shaft 3 at random. For this reason, even when a large snow mass is thrown in, the stirring blade group 4 that rotates in the forward and reverse directions collides with the snow mass from multiple directions and effectively crushes.
　以上のような本実施形態の攪拌式融雪装置１によれば、以下のような効果を奏する。
１．回転軸３に付着する雪が肥大化するのを防止し、融雪効率を向上することができる。
２．融雪したい現場に直接移動させて融雪することができ、雪の運搬作業のために何度もトラックで往復する必要がなくなり、コストや労働力を省けるとともに、深夜の運搬時の騒音や交通渋滞を無くすることができる。
３．蒸気の凝縮伝熱を利用して迅速に融雪するとともに、騒音を低減することができる。
４．融雪槽２に投入された雪が固化するのを抑制することができる。
５．高圧水を噴射して融雪効率を向上するとともに、高圧水の噴射に必要なポンプサイズや消費電力量を低減することができる。
６．大きい雪塊であっても効果的に破砕し、融雪処理を滞りなく進めることができる。
７．融雪水を再利用してランニングコストを低減し、水道施設がない場所でも使用することができる。 According to the stirring type snow melting device 1 of the present embodiment as described above, the following effects can be obtained.
1. The snow adhering to the rotating shaft 3 can be prevented from being enlarged, and the snow melting efficiency can be improved.
2. Snow can be melted by moving directly to the site where you want to melt snow, eliminating the need to reciprocate by truck many times for snow transportation work, saving costs and labor, and reducing noise and traffic congestion during night transportation. Can be eliminated.
3. The snow can be melted quickly by using condensation heat transfer of steam, and noise can be reduced.
4). It can suppress that the snow thrown into the snow melting tank 2 solidifies.
5. In addition to improving snow melting efficiency by injecting high-pressure water, the pump size and power consumption required for injecting high-pressure water can be reduced.
6). Even large snow blocks can be crushed effectively and the snow melting process can proceed without delay.
7. Reusing snowmelt water reduces running costs and can be used even in places where there is no water supply facility.

For example, as shown in FIG. 7, if through holes 42 are formed in each blade 41, it is considered that snowmelt water can flow through each through hole 42 and reduce the resistance of water during stirring.
　さらに、上述した本実施形態のように、融雪水を循環させて再利用する場合、装置内に砂利等が蓄積することが想定される。そこで、例えば、配管の所定位置に砂利を溜めておくための貯留室を設けてもよい。この構成によれば、融雪水に含まれる砂利等は、配管内を循環する途中で貯留室に溜められる。したがって、定期的に貯留室から砂利を取り除くことで、装置内に砂利が貯留し故障してしまうのを未然に防止することができる。 Furthermore, as in the present embodiment described above, when snowmelt water is circulated and reused, it is assumed that gravel or the like accumulates in the apparatus. Therefore, for example, a storage chamber for storing gravel at a predetermined position of the pipe may be provided. According to this configuration, gravel or the like contained in the snowmelt water is stored in the storage chamber while circulating in the pipe. Therefore, by periodically removing gravel from the storage chamber, it is possible to prevent gravel from accumulating in the apparatus and causing failure.
