Description

Technical Field

[0001] This utility model relates to the field of road administration engineering technology, specifically a combustion furnace device. Background Technology

[0002] The definition of a combustion furnace is broad. In daily life, the most common type is a furnace that restricts the combustion of fuel. In road construction projects, a combustion furnace is often used in conjunction with a pot to heat asphalt. A small amount of asphalt is used to repair the edges of roads and other areas that need filling, serving as a supplement to asphalt paving machines.

[0003] Chinese utility model patent CN214891227U, published on November 26, 2021, discloses a combustion furnace for preparing asphalt mixtures. The furnace includes a furnace body with an exhaust hood embedded at the top and a filter screen at the bottom. A horizontal plate is located at the bottom of the furnace body, and a rectangular protective net is fixedly connected to the top edge of the horizontal plate. A striking rod is fixedly connected to one side of the top of the rectangular protective net and one side of the bottom of the filter screen. Multiple slag-leaking holes are evenly chiseled on the horizontal plate. This utility model, a combustion furnace for preparing asphalt mixtures, features a horizontal plate with multiple overhead rods at its top. When used in conjunction with multiple rotating balls, the poured coal can smoothly roll and spread on top of the rotating balls, facilitating complete combustion. Simultaneously, the overhead rods suspend the coal for combustion, allowing air to enter the gaps between the coal particles, resulting in more complete combustion without dead zones. When the coal turns to ash, it can pass through the overhead rods and not accumulate near unburned coal, thus avoiding affecting combustion.

[0004] However, the above-mentioned publicly disclosed solutions have the following shortcomings: the existing combustion furnaces have a small space for heating asphalt, and the heating volume to equipment volume ratio is small; when the heating volume is large, the equipment is large and inconvenient to move to the road construction site; when the equipment is small and easy to carry, the heating volume is small, which means that when a certain volume of asphalt needs to be heated, it needs to be divided into multiple furnaces, resulting in low efficiency. Utility Model Content

[0005] The purpose of this invention is to solve the technical problems of existing combustion furnaces, which have small space for heating asphalt and a small ratio of heating volume to equipment volume; when the heating volume is large, the equipment is bulky and inconvenient to move to the road construction site; when the equipment is small and easy to carry, the heating volume is small, which means that when a certain volume of asphalt needs to be heated, it needs to be divided into multiple furnaces, resulting in low efficiency. The invention provides a combustion furnace device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution;

[0007] The present invention relates to a combustion furnace device, comprising a protective box; multiple stepped grooves are symmetrically provided on both sides of the protective box; a nut pair is slidably connected within the stepped groove; a support rod is sleeved on the nut pair; a primary air inlet is provided inside the protective box; a combustion cylinder is fixedly connected inside the protective box; and a secondary air inlet is provided through the outer surface of the combustion cylinder.

[0008] Furthermore, a side-opening cover is inserted into the side slot of the combustion cylinder; a handle is fixed to the outer surface of the side-opening cover.

[0009] Furthermore, the support rod has a first array hole; a limit rod is inserted into the first array hole.

[0010] The combustion furnace device provided by this utility model has the following beneficial effects:

[0011] 1. This utility model moves the support rod and nut assembly within a stepped groove by pushing the support rod. When the nut assembly is at the horizontal end of the stepped groove, the support rod is retracted. When the nut assembly is in the inclined section of the stepped groove, the support rod is in a supporting state, which can stably support the protective box. By keeping the eight support rods in two sets far apart, the stability of the protective box's grounding is enhanced. At the same time, it can withstand a heavier asphalt heating container, so that the size of the heating container is not synchronized with the size of the combustion furnace. It can be adapted to heating containers of different sizes, thereby improving the efficiency of heating large amounts of asphalt.

[0012] 2. This utility model allows for pushing and pulling the side-opening cover by holding the handle. When the side-opening cover is pulled open, burning material can be placed in. Then, pushing the side-opening cover back to its original position restores it to a complete combustion chamber. This maintains a stable upward flow of air, keeping the flame at its maximum, and also facilitates the addition of burning material. Attached Figure Description

[0018] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0019] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] It should be noted that all directional indications (such as up-down-left-right-forward-backward...) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly. The connection can be a direct connection or an indirect connection.

[0021] Please see Figure 1-3 As shown, a combustion furnace device includes a protective box 1; multiple stepped grooves 2 are symmetrically opened on both sides of the protective box 1; a nut pair 3 is slidably connected within the stepped groove 2; a support rod 4 is sleeved on the nut pair 3; a primary air inlet 14 is opened inside the protective box 1; a combustion cylinder 10 is fixedly connected inside the protective box 1; a secondary air inlet 11 is opened through the outer surface of the combustion cylinder 10. By pushing the support rod 4, the nut pair 3 moves within the stepped groove 2, so that when the nut pair 3 is at the horizontal end of the stepped groove 2, the support rod 4 is retracted; when the nut pair 3 is at the inclined section of the stepped groove 2, the support rod 4 is in a supporting state, which can stably support the protective box 1. By keeping the eight support rods 4 in two sets far apart, the stability of the protective box 1 grounding is enhanced, and it can also withstand a larger weight of asphalt heating container, so that the size of the heating container is not synchronized with the size of the combustion furnace, and it can be adapted to heating containers of different sizes, thereby improving the efficiency of heating large amounts of asphalt.

[0022] A side opening cover 12 is inserted into the side slot of the combustion tube 10; a handle 13 is fixed to the outer surface of the side opening cover 12. By holding the handle 13, the side opening cover 12 can be pushed and pulled. When the side opening cover 12 is opened, the burning material can be put in. Then push the side opening cover 12 back to its original position, so that the combustion tube 10 is restored to a complete state. This can maintain a stable upward flow of air, keep the flame at its maximum, and also facilitate the addition of burning material.

[0023] The support rod 4 has a first array hole 5; a limiting rod 6 is inserted into the first array hole 5. By using the limiting rod 6 in conjunction with the first array hole 5, the distance between the two limiting rods 6 can be changed, thereby adapting to heated asphalt containers of different diameters and maintaining a more stable placement.

[0024] Limiting rod 6 is fitted with limiting plate 7; limiting plate 7 has a second array hole 8. By using two limiting plates 7 in conjunction with two limiting rods 6, the heated asphalt container can be stably restricted, thus making the heating of asphalt more stable and adaptable to heated asphalt containers of different diameters.

[0025] A movable plate 9 is fixed to the opening of the protective box 1 by a hinge. The magnetic attraction between the movable plate 9 and the protective box 1 is achieved by a magnet that is fixed in a slot at the overlap of the movable plate 9 and the protective box 1. This allows the protective box 1 to be sealed, so that the airflow into the combustion cylinder 10 remains stable and the flame remains stable. At the same time, when the movable plate 9 is kept in a horizontal state, a large amount of combustible material can be placed, making it more convenient to fill the combustion cylinder 10 with combustible material.

[0026] The protective box 1 is made of flame-retardant material; the combustion cylinder 10 is made of cast iron, so that the combustion cylinder 10 will not melt or deform at high temperatures and can be used for long-term normal heating of asphalt; the protective box 1 can withstand the temperature generated by combustion in the combustion cylinder 10, thereby reducing the heat from being radiated to the human body and ensuring the safety of the operator during use.
