Description

[Technical field]

[0001] The present invention relates to an oxygen supply type high speed incineration apparatus having one or more air injection members with air injection ports that forcibly inject air toward a combustible part in order to incinerate combustion materials at high temperature and high speed. [Background technology]

[0002] In conventional river and road maintenance work, weeds on embankment slopes and road shoulders are cut down and dried on the spot, then raked into strips on the ground at the top of the slope and incinerated on the ground. However, this method of incinerating weeds, etc., was carried out on damp ground, so it was not possible to completely burn them, and a lot of smoke was generated, which hindered the visibility of drivers of vehicles traveling on the roads on the embankments or on general roads, and smoke was blown into nearby houses and ashes were splashed on laundry, resulting in complaints. Therefore, in order to prevent such complaints from third parties, a method has been adopted in which grass cuttings, etc. are transported to a place where they are less likely to affect third parties, piled up, and then incinerated.

[0003] In order to solve these problems, the inventors have proposed a V-shaped combustible incineration device having an air injection member (Patent Document 1). With this incineration device, by supplying air, it is possible to completely combust and incinerate at a high temperature, so that the generation of smoke can be significantly reduced, the incineration time can be shortened, and the incineration efficiency can be improved by two to three times. As a result, while in the past, when incineration took several days, it was greatly dependent on the weather, it is now possible to perform a large amount of incineration work in a short time on a good weather day, so the number of cases where work to make up for delays had to be done on holidays has drastically decreased, and overtime work and holiday work have been eliminated, contributing to work style reform for workers engaged in this work.

[0004] However, this incineration device has a V-shaped combustible material loading section that gets wider toward the top, so when it is transported, the width of the upper part exceeds the width of the transport vehicle, and so it is transported by dividing it vertically into three parts, including the incineration rack base, the right grass clippings loading rack part, the central grass clippings loading rack main body, and the left grass clippings loading rack member. There is also the problem that two trucks are required to transport it, one for the left and right grass clippings loading racks and one for the central grass clippings loading rack main body. This incineration device is assembled on site, but because it is a heavy item, heavy machinery such as cranes and backhoes are required for the assembly work, and there is the problem that it takes time and money to complete the assembly.

[0005] [Patent Document 1] Patent Publication No. 2021-55930 Summary of the Invention [Problem to be solved by the invention]

[0006] The present invention has been made in consideration of such problems, and has an object to provide an oxygen-supply-type high-speed incineration apparatus having one or more air injection members with air injection ports that forcibly inject air toward the burning part of combustible materials in order to incinerate the materials at high temperature and high speed, which is easy to transport and assemble. [Means for solving the problem]

[0007] In order to achieve the above-mentioned main object, the present invention adopts the following means.

[0008] The oxygen supply type high speed incineration apparatus according to the present invention comprises: A combustible incineration rack having a central incineration rack part formed on a flat surface, the central incineration rack part being arranged with a space between the central incineration rack part and the ground below for placing combustible materials thereon and incinerating the combustible materials thereon, the central incineration rack part being fixed in a parallel state with a plurality of rod-shaped members made of steel or heat-resistant members, and a left and right inclined rack part arranged in a V shape so that the left and right inclined rack parts are diverged upward from the central incineration rack part; and one or more air injection members each having an air injection port which can be arranged at any position of the central incineration rack and which forcibly injects air toward the combustion part of the combustible material in order to incinerate the combustion material at a high temperature and high speed. The rod-shaped members of the left and right inclined base sections are characterized in that they have at least one of sliding, folding and detaching functions or any combination of these functions so that the protruding length can be adjusted.

[0009] In the oxygen supply type high-speed incineration apparatus according to the present invention, the rod-shaped members that form the left and right inclined rack parts formed on the left and right sides of the central incineration rack part of the combustible incineration rack are formed so that the protruding length can be changed, and the rod-shaped members are formed so that they can be inserted detachably, or are slidable or foldable within the width of the central incineration rack part, so that the protruding amount of each rod-shaped member can be changed manually. As a result, cranes and heavy machinery are no longer necessary after the central incineration rack part is installed at the desired location, and the oxygen supply type high-speed incineration apparatus can be installed manually thereafter. In addition, since the load on the transport vehicle is only the width of the central incineration rack part, the loading area is narrow, the loading amount can be greatly reduced, and only one truck is required for transportation.

[0010] In addition, the left and right inclined frame parts may be provided with comb-shaped planar members having a narrower interval than the interval between the left and right inclined frame parts, which are made of rod-shaped members thinner than the rod-shaped members used for the left and right inclined frame parts, so that the comb-shaped planar members can be freely attached to the left and right inclined frame parts. This makes it possible to reduce the number of rod-shaped members forming the left and right inclined frame parts, and to provide an oxygen-supply type high-speed incineration apparatus that is lighter and can be assembled more quickly than conventional oxygen-supply type high-speed incineration apparatuses.

[0011] Furthermore, the comb-shaped planar member may have a hook portion that can be hooked into the insertion hole when the rod-shaped member is a cylindrical member. By providing the hook portion, the comb-shaped planar member can be easily attached.

[0012] Furthermore, the left and right inclined base parts may be provided with mesh-like planar members formed in a mesh shape by rod-like members so as to be freely attached thereto. When burning small vegetation, the possibility of the vegetation not being completely burned falling can be reduced by using a finer mesh-like planar member. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. Note that the embodiment and drawings described below are intended to exemplify a part of the embodiment of the present invention, and are not intended to be used for the purpose of limiting the configuration of the embodiment. In addition, the same or similar reference numerals are used to designate corresponding components in each drawing.

[0015] (First embodiment) As shown in FIG. 1, the oxygen supply type high speed incineration apparatus 100 according to the first embodiment mainly comprises a central incineration stand 10 made of horizontally arranged rod-shaped members 13, left and right inclined stand members 20 arranged in a V shape so as to spread upward from the left and right sides of the central incineration stand 10, an air injection member 30 that ejects air onto combustible materials such as grass clippings placed on the central incineration stand 10, and a comb-shaped planar member 40 that is arranged on the left and right rod-shaped members 13.

[0016] The incineration central rack 10 is made by arranging a plurality of rod-shaped members 13 horizontally in parallel. The interval between the rod-shaped members 13 is preferably set to 20 cm to 50 cm. If the interval is too narrow, the weight becomes heavy, and if the gap is too wide, the grass clippings cannot be held. The rod-shaped members 13 used are not limited, and may be steel of any shape. It is preferable to use a single pipe with a space formed inside, such as an H-shaped steel, a round pipe, or a square pipe. As for the heat-resistant material, there is no particular preference for the material as long as it has excellent heat resistance, such as steel or ceramic. It is preferable to support the incineration central rack 10 at a height of about 50 cm to 100 cm from the ground.

[0017] The left and right inclined rack parts 20 are arranged in a V-shape on both sides of the central rack part 10 for incineration, with a wide upper gap and a narrow lower gap. The left and right inclined rack parts 20 of the first embodiment are formed by bending so as to communicate with the parallel rod-shaped members 13 forming the central rack part 10 for incineration, and are composed of a lower rod-shaped member 13b having a hollow insertion hole 13a and an upper rod-shaped member 13c that can be inserted into the insertion hole 13a of the lower rod-shaped member 13b. By configuring in this way, the upper rod-shaped members 13c can be attached and detached one by one to the insertion hole 13a of the lower rod-shaped member 13b, and the protruding length of the rod-shaped members 13 of the left and right inclined rack parts 20 can be adjusted by attaching and detaching them. Since one of the upper rod-shaped members 13c is lightweight, it can be freely attached and detached by human power. Therefore, after the incineration central rack unit 10 is set in a predetermined position by a crane, the incineration central rack unit 10 can be completed by human power alone.

[0018] The air injection member 30 has one or more air injection ports 35, and injects air from a compressor (not shown) from the air injection ports 35. The injection direction of the multiple air injection ports 35 may be a fixed direction or may be in different directions. The air injection member 30 is disposed on the above-mentioned central incineration rack 10, and is set to face upward so as to inject air (oxygen) from the air injection port 35 toward the burning part of the combustible material.

[0019] The comb-shaped planar member 40 is a member attached to the left and right inclined platform 20 to adjust the interval between the parallel rod-shaped members 13 of the left and right inclined platform 20. Specifically, when the interval between the left and right inclined platform 20 is too wide, it is used to adjust the interval to be narrower. The comb-shaped planar member 40 is formed as a planar member arranged to have an interval narrower than the interval between the left and right inclined platform 20 using a thin rod-shaped member 41 thinner than the rod-shaped member 13 used in the left and right inclined platform 20. The comb-shaped planar member 40 has a hook-shaped hook portion 45 that hooks onto the insertion hole 13d formed in the upper rod-shaped member 13c formed of a cylindrical member, and can be easily attached to the left and right inclined platform 20 by human force. In this way, by providing the comb-shaped planar member 40, the interval between the rod-shaped members 13 of the left and right inclined platform 20 can be widened, and the weight of the incineration central platform 10 and the left and right inclined platform 20 can be reduced. As shown in the figure, a mesh-like planar member 46 formed in a mesh shape may be used instead of the comb-like planar member 40. The comb-like planar member 40 is attached to the left and right inclined base parts 20 to adjust the distance between the parallel rod-like members 13 of the left and right inclined base parts 20, and may not be used if the distance between the lower rod-like member 13b and the upper rod-like member 13c attached to the rod-like member 13 is such that the material to be burned does not spill out before combustion.

[0020] The oxygen supply type high-speed incineration apparatus 100 constructed as described above is used as follows. First, the central incineration rack unit 10 is installed at the place where incineration is to be performed using heavy machinery or a crane. Then, the upper rod-shaped members 13c are manually inserted one by one into the insertion holes 13a of the lower rod-shaped members 13b constituting the left and right inclined rack units 20 formed by bending so as to communicate with the parallel rod-shaped members 13 that form the central incineration rack unit 10, thereby constructing the left and right inclined rack units 20, and the oxygen supply type high-speed incineration apparatus 100 is completed. Combustible materials such as grass clippings are placed on the central incineration rack unit 10 and the left and right inclined rack units 20 of the assembled oxygen supply type high-speed incineration apparatus 100 using heavy machinery or the like. Then, air is injected from the air injection port 35 of the air injection member 30 toward the burning part of the combustible materials at the same time as the combustible materials are ignited. By injecting air into the burning part, oxygen is supplied to the burning part, improving the combustion effect. When the combustibles are burned and reduced, more combustibles are added. At this time, the combustibles that have finished burning shrink and become brittle when they turn into ash, so they fall to the ground. However, even if there are lumps of ash remaining, the work of adding combustibles is performed using heavy machinery with a scissor bucket, so that the burnt and brittle ash is finely crushed and dropped between the rod-shaped members 13 by the combustibles placed on the central incineration rack 10, and the incineration work can be continued by securing space to place new combustibles. The stronger the firepower becomes by adding combustibles, the stronger the air flow that rises at the same time as the flames becomes, and the air (oxygen) on the underside of the central incineration rack 10 is drawn in, further increasing the firepower. Air is injected from the air injection port 35 of the air injection member 30, which is also provided, to the burning part of the combustibles, supplying air (oxygen) to the burning part, increasing the firepower and making it possible to control the generation of smoke by complete combustion at high temperatures, which has made it possible to significantly reduce the amount of smoke compared to the past.

[0021] According to the oxygen supply type high speed incineration apparatus 100 of the present invention, the air injection member 30 is provided for the purpose of forcibly supplying air (oxygen) from the central incineration stand 10 to the combustible material burning section by injection, so that the burning section further promotes combustion and increases the burning temperature, thereby greatly accelerating the incineration speed. Also, since the upper rod-shaped member 13c can be removed by pulling it out of the insertion hole when transporting, the removed upper rod-shaped member 13c can be stored in the hollow part of the framework structure of the central incineration stand 10, so that the loading area of ​​the transport vehicle is narrow and the loading amount can be greatly reduced because the width of the central incineration stand 10 is the only width of the load on the transport vehicle.

[0022] Second embodiment The figure shows an oxygen supply type rapid incineration apparatus 100 according to the second embodiment. The oxygen supply type rapid incineration apparatus 100 according to the second embodiment differs in the shape of the rod members 13b, 13c of the left and right inclined platform parts 20, and other configurations are the same as those of the first embodiment, so explanations will be omitted.

[0023] As shown in Fig. 4, the left-right inclined stand section 20 of the oxygen supply type high-speed incineration apparatus 100 according to the second embodiment is formed with an upper rod-shaped member 13c slidably relative to a lower rod-shaped member 13b having a hollow insertion hole 13a, and a slide fixing pin 14 is inserted into fixing holes 14a formed in the lower rod-shaped member 13b and the upper rod-shaped member 13c to fix the rod-shaped member 13c to a predetermined protruding amount. In this way, by sliding the upper rod-shaped member 13c downward, the protruding amount of the upper rod-shaped member 13c can be reduced. This narrows the width of the oxygen supply type high-speed incineration apparatus 100, so that the loading area on the transport vehicle can be narrowed and the loading amount can be greatly reduced.

[0024] Third embodiment The oxygen supply type high-speed incineration apparatus 100 according to the third embodiment is shown in Fig. 5. The oxygen supply type high-speed incineration apparatus 100 according to the third embodiment differs in the shape of the rod-shaped members of the left and right inclined rack parts 20, and other configurations are the same as those of the first embodiment, so the description will be omitted.

[0025] The left and right inclined platform section 20 of the oxygen supply type high speed incineration apparatus 100 according to the second embodiment has a hinge 15 between the lower rod-shaped member 13b and the upper rod-shaped member 13c, and the upper rod-shaped member 13c is formed so as to be freely foldable relative to the lower rod-shaped member 13b. By folding it in this way, the amount of protrusion of the upper rod-shaped member 13c can be reduced. This narrows the width of the oxygen supply type high speed incineration apparatus 100, so that the loading area on the transport vehicle can be narrowed and the loading amount can be greatly reduced.

[0026] The removable rod-shaped member of the first embodiment, the slidable rod-shaped member of the second embodiment, and the foldable rod-shaped member of the third embodiment may be used in any combination. For example, the rod-shaped member may be formed to be foldable as in the third embodiment, and the upper rod-shaped member 13c may be provided as removable.

[0027] The present invention is not limited to the above-described embodiments, and may be embodied in various forms within the technical scope of the present invention.

[0028] As shown in the above-mentioned embodiment, the present invention can be used as an incineration facility. [Explanation of symbols]
