Description

一种篝火炉  a campfire 技术领域Technical field
本 发明涉及 一种篝火炉,尤其有关于一种使用生物燃料的安全、易控篝火发生装置。 BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a bonfire furnace, and more particularly to a safe, easy-to-control bonfire generating device using biofuels.
背景技术Background technique
燃放篝火是人类一种古老的传统,深受很多国家人们的喜爱。迄今为止,燃放篝火的方式基本上是在地面或一个容器内堆放木柴、煤、木炭然后点燃。这种传统篝火燃放方式带来以下主要问题。第一,安全问题。燃烧所产生的火星或火焰随风飞舞,很容易引燃其他物体或烫伤人或其他动物。尤其在天然木材或煤炭在燃烧中产生爆燃现象时,情况更加危险。第二,火焰控制问题。这种篝火燃放方式中点火和熄火往往都需要很长的时间。 木材和煤炭都不容易用普通点火器具如打火机、点火枪等直接点燃,而熄火一般只能采用水浇熄或自然燃尽的方式。水浇熄需要准备足量的水源,自然燃尽往往需要人员守候。不论哪种方式,控制火焰的效率都较低。另外,由于火焰完全受自然风的影响,所以在风力较大时、尤其是有较大阵风的时候篝火就完全不能够燃放。第三,环境影响问题。传统燃放方式在开始燃烧至充分燃烧的很长一段时间内都会产生浓烟,对周围人员的健康和环境造成负面影响。 而燃烧过后留下的灰烬、残骸、和对地面烧烤所留下的污迹也非常难以清除,这种情况在用水熄灭篝火的情况下尤为严重。第四,火焰高度不高的问题。传统篝火堆火焰高度有限,不能形成熊熊火焰的壮观景象。第五,移动不便。 The bonfire is an ancient tradition of human beings and is loved by people in many countries. So far, the way to set up a bonfire is basically to put wood, coal, charcoal on the ground or in a container and then ignite. This traditional bonfire discharge method brings the following major problems. First, security issues. The sparks or flames produced by the burning dance with the wind, and it is easy to ignite other objects or burn people or other animals. Especially when natural wood or coal produces a deflagration in combustion, the situation is even more dangerous. Second, the flame control problem. Ignition and flameout in this type of bonfire discharge often take a long time. Wood and coal are not easily ignited by ordinary ignition devices such as lighters, igniters, etc., and flameouts can only be used in the form of water quenching or natural burning. Water quenching requires a sufficient amount of water to be prepared, and natural burning often requires personnel to wait. Either way, the efficiency of controlling the flame is low. In addition, since the flame is completely affected by the natural wind, the bonfire cannot be discharged at all when the wind is large, especially when there is a large gust. Third, environmental impact issues. Conventional discharge methods generate smoke over a long period of time from the start of combustion to full combustion, which has a negative impact on the health and environment of the surrounding people. The ash, wreckage, and smudges left on the ground barbecue after burning are also very difficult to remove, especially in the case of extinguishing bonfires with water. Fourth, the problem of low flame height. The traditional bonfire flames are limited in height and cannot form a spectacular sight of a blazing flame. Fifth, it is inconvenient to move.
技术问题technical problem
本发明所要解决的主要技术问题是提供一种篝火炉,该篝火炉不会产生飞出炉体的火星,火焰在人员高度范围内也不会随风舞动,可以为篝火带来极大的安全性。The main technical problem to be solved by the present invention is to provide a bonfire furnace which does not generate Mars flying out of the furnace body, and the flame does not dance with the wind in the height range of the person, which can bring great safety to the bonfire. .
本发明所要解决的另一个技术问题是提供一种篝火炉,该篝火炉点火和熄火都只需要使用者揿动按钮即可在很短的时间内或产生篝火或完全熄灭。Another technical problem to be solved by the present invention is to provide a simmering furnace which can only ignite or completely extinguish the igniting or extinguishing in a short period of time by the user pushing the button.
本发明所要解决的另一个技术问题是提供一种篝火炉,该篝火炉在持续或阵风风力较大时仍可正常使用。Another technical problem to be solved by the present invention is to provide a simmering furnace which can be used normally even when the wind is continuous or the gust wind is large.
本发明所要解决的另一个技术问题是提供一种篝火炉,该篝火炉烟尘和灰烬量都很少,燃烧后也不会在地面留下难以清除的污迹。Another technical problem to be solved by the present invention is to provide a simmering furnace which has a small amount of soot and ash, and which does not leave a stain which is difficult to remove on the ground after burning.
本发明所要解决的另一个技术问题是提供一种篝火炉,该篝火炉能够形成超过人员高度的火焰,能够形成壮观的篝火火焰景象。Another technical problem to be solved by the present invention is to provide a bonfire furnace capable of forming a flame exceeding the height of a person and capable of forming a spectacular bonfire flame scene.
本发明所要解决的另一个技术问题是提供一种篝火炉,该篝火炉容易移动,即方便通过人员搬动在短距离范围内移动,也方便使用交通工具进行长距离移动。Another technical problem to be solved by the present invention is to provide a bonfire furnace which is easy to move, that is, it is convenient to move within a short distance by a person to move, and it is also convenient to use a vehicle for long-distance movement.
技术解决方案Technical solution
为了解决上述技术问题,本发明提供有一种篝火炉,该篝火炉使用生物质燃料颗粒并 包括 一个可安放于地面上的本体,本体包括一个燃烧箱和一个辅助设备箱。燃烧箱包括有一个可平放于地面之上的底面,一个沿底面周边向上延伸的侧面,一个与侧面上缘相连接并与底面相对的顶面,侧面上设有一个可开关的箱门。燃烧箱内容纳有一个燃烧器。燃烧器具有一个燃料架板,一个沿燃料架板周边向上延伸的侧板,一个位于侧板上方并与燃料架板相对的顶板,一个位于燃料架板下方的鼓风区,一个由侧板在燃料架板上方围成的燃烧区。鼓风区上辅助设备箱一侧形成有一条送风孔,送风孔相对的的一侧形成有一个前方开口。燃料架板上开设有数个通风孔隙。顶板上燃烧区的上方固设有一个通向燃烧区的火焰筒,火焰筒的周边上开设有数个进风孔。辅助设备箱内容纳有燃料输送机构和电气设备。燃料输送机构包括一个料斗,一条一端与料斗下方的出口相连通另一端伸入燃烧区中的送料筒,以及一条可转动的容纳于送料筒中的燃料螺旋推送杆。电气设备包括一台与送风孔相连通的鼓风机、一台驱动燃料螺旋推送杆的送料电机、一个电源和一个电源开关。在本体的顶面之上还安装有一个火焰部,火焰部是一个由耐高温的玻璃围绕火焰筒而形成的一个火焰升腾空间。 In order to solve the above technical problems, the present invention provides a bonfire furnace using biomass fuel particles and including A body that can be placed on the ground, the body includes a combustion box and an auxiliary equipment box. The combustion box includes a bottom surface that can be laid flat on the ground, a side that extends upward along the periphery of the bottom surface, a top surface that is connected to the upper edge of the side surface and opposite the bottom surface, and a switchable door is provided on the side. There is a burner in the combustion chamber. The burner has a fuel rack plate, a side panel extending upwardly along the periphery of the fuel rack plate, a top plate above the side plate and opposite the fuel rack plate, a blast zone located below the fuel shelf plate, and a side panel at a combustion zone enclosed above the fuel shelf. A ventilation hole is formed on one side of the auxiliary equipment box on the blast zone, and a front opening is formed on the opposite side of the air supply hole. There are several ventilation holes on the fuel rack. A flame tube leading to the combustion zone is fixed above the combustion zone on the top plate, and a plurality of air inlet holes are opened in the periphery of the flame cylinder. The auxiliary equipment box houses a fuel delivery mechanism and electrical equipment. The fuel delivery mechanism includes a hopper, a delivery barrel having one end communicating with the outlet below the hopper and the other end extending into the combustion zone, and a rotatable fuel auger rod accommodated in the delivery cylinder. The electrical equipment includes a blower that communicates with the air supply aperture, a feed motor that drives the fuel auger, a power supply, and a power switch. A flame portion is also mounted above the top surface of the body, and the flame portion is a flame rising space formed by the high temperature resistant glass surrounding the flame tube.
有益效果Beneficial effect
本发明所带来的有益效果是第一,由于燃烧过程主要是在燃烧器内完成,同时鼓风式的燃烧可以大幅增加燃烧的充分性,由微小燃料颗粒所构成的火星不容易脱离燃烧器再通过较长的火焰部飞溅至外部;同时火焰在火焰部内跳动而不易受风力影响,所以相较自然篝火安全性大大提高。第二,当使用者开动篝火炉后,高温的点火棒和鼓风机可以迅速使燃料充分燃烧,产生所需的火焰;而在使用者关闭篝火炉后,鼓风机可以继续工作一段时间,使燃烧室内的燃料可以迅速燃尽。这样就大幅提升了篝火产生和熄灭的效率。第三,篝火炉所使用的是生物质燃料颗粒。生物质燃料本身即比大密度的木材和煤炭易燃烧、烟雾少、灰烬少, 颗粒状的生物质燃料尤其是在点燃初期和熄灭时进一步减少了点燃时间,烟雾和灰烬量。第四,炉内的灰烬集中在燃烧器内,通过打开箱门很容易清理;炉内的燃烧也集中在燃烧器内,不会在地面形成难以清除的污迹。第五,火焰筒上进风孔的存在可以使外部空气进入并在火焰部内高速流动,带动产生远高于自然燃烧篝火高度的火焰,形成壮观的篝火景象。第六,相较于传统篝火,篝火炉易于移动。既可以在短距离内通过人员搬动来选择更合适的燃烧地点,也适于通过交通工具长距离搬移。 The beneficial effects of the present invention are first, since the combustion process is mainly completed in the burner, and the blast-type combustion can greatly increase the sufficiency of combustion, and Mars composed of tiny fuel particles is not easily separated from the burner. Then, the flame is splashed to the outside through the longer flame portion; at the same time, the flame jumps in the flame portion and is not easily affected by the wind, so the safety of the natural bonfire is greatly improved. Second, when the user activates the oven, the high temperature ignition rod and blower can quickly burn the fuel to produce the desired flame; and after the user closes the furnace, the blower can continue to work for a period of time, so that the combustion chamber The fuel can burn out quickly. This greatly increases the efficiency of the bonfire generation and extinction. Third, biomass fuel pellets are used in the furnace. Biomass fuel itself is more flammable, less smog, and less ash than large-density wood and coal. Granular biomass fuels further reduce ignition time, smoke and ash emissions, especially during initial ignition and extinction. Fourth, the ash in the furnace is concentrated in the burner, which is easy to clean by opening the door; the combustion in the furnace is also concentrated in the burner, and no hard-to-clear smudges are formed on the ground. Fifth, the presence of the air inlet hole on the flame tube allows the outside air to enter and flow at a high speed in the flame portion, causing a flame that is much higher than the natural burning bonfire height to form a spectacular bonfire scene. Sixth, the stove is easy to move compared to the traditional campfire. It is possible to select a more suitable burning location by personnel movement within a short distance, and also to move long distances by means of vehicles.

燃料 70 为生物质燃料,是由稻草、木屑、农作物秸秆等粉碎压制而成的小颗粒。Fuel 70 is a biomass fuel and is a small particle that is crushed and pressed from straw, wood chips, and crop straw.
在使用时,使用者可以先在所需位置的地面上将本发明的篝火炉摆放平稳,然后向料斗41内倒入燃料70。当使用者按下电源开关55后,电源指示灯56亮起,表示电源接通,篝火炉开始工作。此时送料电机52转动,驱动燃料螺旋推送杆43将燃料70送入燃烧器30中,燃料70在重力作用下落在燃料架板31上。同时,通电的点火棒53变成炽热,通过点火棒窗口312将燃料架板31上燃烧区35内的燃料70点燃。也是在同时,鼓风机51开始向鼓风区34内送风,风通过燃料架板31上开设的通风孔隙311进入燃烧区35,为燃料70的燃烧提供所需的氧气。当燃料70燃烧到一定程度时会产生高浓度的甲烷气体,这些甲烷气体在鼓风机51产生的气流的作用下快速流经火焰筒37。同时,由于玻璃圆筒201上部和下部的温差,火焰筒37外部的空气会经进风孔371流入火焰筒37内部,并在火焰部2的火焰升腾空间内快速向上流动。此时,高温高浓度的甲烷气体遇到氧气开始充分燃烧,产生熊熊的火焰。火焰在火焰部2上、下温差作用下产生的气流的带动下被拉长,在整个火焰部2内形成高高的熊熊火焰。图1显示的即为篝火燃烧的状态。在燃料70本身可以持续燃烧后,电路控制点火棒53断电,节约电能。In use, the user can first place the bonfire furnace of the present invention on the ground at the desired location and then pour the fuel 70 into the hopper 41. When the user presses the power switch 55, the power indicator light 56 illuminates, indicating that the power is turned on, and the stove is started to work. At this time, the feed motor 52 rotates, and the fuel auger rod 43 is driven to feed the fuel 70 into the burner 30, and the fuel 70 falls by gravity on the fuel rack 31. At the same time, the energized ignition rod 53 becomes hot, and the fuel 70 in the combustion zone 35 on the fuel rack 31 is ignited through the ignition rod window 312. Also at the same time, the blower 51 begins to blow air into the blast zone 34, and the wind enters the combustion zone 35 through the venting apertures 311 formed in the fuel shelf plate 31 to provide the required oxygen for combustion of the fuel 70. When the fuel 70 is burned to a certain extent, a high concentration of methane gas is generated, which rapidly flows through the flame cylinder 37 by the air flow generated by the blower 51. At the same time, due to the temperature difference between the upper portion and the lower portion of the glass cylinder 201, the air outside the flame tube 37 flows into the inside of the flame tube 37 through the air inlet hole 371, and flows upward rapidly in the flame rising space of the flame portion 2. At this time, the high-temperature and high-concentration methane gas starts to fully burn with oxygen, resulting in a blazing flame. The flame is elongated by the airflow generated by the upper and lower temperature differences of the flame portion 2, and a high blazing flame is formed in the entire flame portion 2. Figure 1 shows the state of bonfire combustion. After the fuel 70 itself can continue to burn, the circuit controls the ignition rod 53 to be powered off, saving electrical energy.
当需要停止燃烧的时候,使用者可以断开电源开关55,电源指示灯56熄灭,送料电机52停止转动,鼓风机51停止。没有新的燃料70供给燃烧,燃烧区35内的燃料将很快燃尽,使用者即可打开箱门121,从燃烧器30的前方开口342清理燃烧区35内的灰烬。 燃料架板 31 的边缘部分可以向上偏斜有一定角度,在中部形成一片低地 313 。低地 313 可以聚拢燃料 70 ,从而避免边缘燃料燃烧受热不充分产生黑烟。When it is necessary to stop the combustion, the user can turn off the power switch 55, the power indicator light 56 is turned off, the feed motor 52 stops rotating, and the blower 51 stops. Without the new fuel 70 being supplied to the combustion, the fuel in the combustion zone 35 will burn out quickly, and the user can open the tank door 121 and clean the ash in the combustion zone 35 from the front opening 342 of the burner 30. The edge portion of the fuel rack plate 31 may be inclined upward at an angle to form a low ground 313 in the middle. Lowland 313 can gather fuel 70 In order to avoid excessive combustion of the edge fuel, the black smoke is not sufficiently generated.
小颗粒状的生物燃料70相比于体积较大的木材和煤炭来讲,更容易被引燃,再加上高温炽热的点火棒53和充足的氧气,本发明的篝火炉可以在非常短的时间内形成壮观的篝火。也由于生物燃料70很容易被引燃,本发明也可以不使用点火棒53而是用点燃的纸张、浸有酒精或汽油的纸张等引燃物点燃。在这种情况下,电路中的点火棒53可以被省略,燃料架板31上也可以不开设点火棒窗口312。在仅有玻璃圆筒201而没有玻璃内筒202的情况下,玻璃圆筒201的底部靠近火焰筒37的部分会形成一个滞流区。滞流区内空气流动缓慢燃烧不充分,因此会形成黑烟并在此处的玻璃圆筒201内形成由未充分燃烧的微碳颗粒构成的黑垢,影响篝火的外观。直径与火焰筒37基本相同的玻璃内筒202内可以消除滞流区、形成快速流动的火焰,不容易产生黑垢。即使偶尔产生少量的黑垢,快速流动的火焰也可以随后马上将其充分的燃烧尽,使黑垢快速消失。透明的玻璃内筒202也不会影响对火焰的观赏。The small granular biofuel 70 is easier to ignite than the bulky wood and coal, coupled with the high temperature hot ignition rod 53 and sufficient oxygen, the furnace of the present invention can be very short A spectacular bonfire is formed during the time. Also, since the biofuel 70 is easily ignited, the present invention can also ignite with an ignition material such as ignited paper, paper impregnated with alcohol or gasoline, without using the ignition rod 53. In this case, the ignition rod 53 in the circuit can be omitted, and the ignition rod window 312 may not be provided on the fuel shelf plate 31. In the case where only the glass cylinder 201 is present without the glass inner cylinder 202, the portion of the bottom of the glass cylinder 201 near the flame cylinder 37 forms a stagnant zone. The air flow in the stagnation zone is slowly burned insufficiently, so that black smoke is formed and black scale composed of under-burned micro-carbon particles is formed in the glass cylinder 201 here, which affects the appearance of the bonfire. The glass inner cylinder 202 having substantially the same diameter as the flame tube 37 can eliminate the stagnant zone, form a fast flowing flame, and is less prone to black scale. Even if a small amount of black scale is occasionally produced, the fast-flowing flame can be fully burned out immediately, so that the black scale quickly disappears. The transparent glass inner cylinder 202 also does not affect the viewing of the flame.
如图 7-11 所示为本发明一种篝火炉的第二实施例。在该实施例中,侧壁 32 的上缘与顶板 33 相连接,送料筒 42 通过侧壁 32 上辅助设备箱 20 一侧开设的一个开口 321 伸入燃烧区 35 中。A second embodiment of a simmering furnace of the present invention is shown in Figs. 7-11.
