Description

Technical Field

[0001] This utility model relates to the field of return air furnace technology, specifically to an energy-saving gasification burner head based on a return air furnace. Background Technology

[0002] A return air furnace is a common heating device, mainly used for heating homes, offices, and other places. It works by burning fuels (such as industrial alcohol, domestic methanol, or natural gas) to generate heat, and then using a flue design to circulate the hot air within the furnace, thereby improving thermal efficiency and dissipating heat evenly.

[0003] Traditional return air furnaces typically use a coal-fired furnace structure. Because heat is lost quickly in a coal-fired furnace, materials need to be added continuously in a short period of time, resulting in fuel waste. Furthermore, due to the limited number of channels in traditional coal-fired furnaces, heat flows rapidly to the outside, leading to incomplete heat utilization and affecting the full utilization of thermal energy.

[0004] Therefore, an energy-saving gasification burner based on a return air furnace is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides an energy-saving gasification burner head based on a return air furnace, which can solve problems such as low heating efficiency and low heat utilization efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: it includes a support cylinder and a through pipe built into the support cylinder, wherein a thin tube is built into the through pipe, the thin tube penetrates the support cylinder, and the through pipe extends outward from the support cylinder through the inside of the support cylinder.

[0007] A connecting cylinder is provided below the support cylinder, and a positioning ring is provided below the thin tube. The thin tube and the connecting cylinder pass through and are inserted into the inside of the through pipe. The positioning ring is located on the lower end face of the connecting cylinder.

[0008] Preferably, the support cylinder is cylindrical in shape, and a through hole is provided through the inner wall of the cylinder, the through hole extending to the outside of the support cylinder, and the thin tube is inserted through the through hole.

[0009] Preferably, a side ring is fixedly fitted on the side of the support cylinder away from the connecting cylinder, and the specifications of the side ring are larger than those of the support cylinder.

[0010] Preferably, the connecting cylinder has a through hole with the same specifications as the through hole inside, and a connector is installed on the outer side of the connecting cylinder, which communicates with the inside of the connecting cylinder.

[0011] Preferably, a plurality of conduits are installed on the lower half of the outer side of the through pipe, the conduits being evenly distributed in a ring on the outer side of the through pipe, and the conduits communicating with the inside of the through pipe.

[0012] Preferably, a plurality of guide holes are provided through the outer side of the through pipe, the guide holes extending into the inside of the through pipe, and a cone-shaped head is installed at the upper end of the through pipe, the upper edge of the cone-shaped head being rounded.

[0013] Preferably, the connection between the conduit and the through pipe is welded, the through pipe is welded to the inner wall of the support cylinder, the through pipe is welded to the conical head, the thin tube is welded to the positioning ring, and the positioning ring is welded to the connecting cylinder.

[0014] Compared with the prior art, this utility model provides an energy-saving gasification burner head based on a return air furnace, which has the following beneficial effects:

[0015] 1. The energy-saving gasification burner head of this return air furnace, through the flow inside the thin tube, the transfer of heat between the inner wall of the through tube and the outer side of the thin tube, and the transfer of heat between the outer side of the through tube and the inner wall of the support cylinder, allows the support cylinder, through tube, and thin tube to be used after assembly. At the same time, it has multi-layer flow control support, allowing heat to flow between multiple spaces, so that the heat between two adjacent spaces forms a complementary heating and heat preservation effect, improving the situation of preventing rapid heat loss while allowing heat to flow.

[0016] 2. The energy-saving gasification burner head of this return air furnace, under the restriction of the conical shape of the head itself, causes the heat flow to be restricted to a short distance when it flows here, so that the heat flow is concentrated and compressed here, thereby increasing the heat flow time inside the pipe.

[0017] 3. The energy-saving gasification burner head of this return air furnace, under continuous accumulation and compression, causes the heat flow to flow outward through the guide hole, and the heat flow out from the inside of the pipe in multiple directions, improving the multidirectional heat flow and improving the uniformity and comprehensiveness of heating.

[0018] 4. The energy-saving gasification burner head of this return air furnace is connected to the connector and the positioning ring through the connecting cylinder, so that heat can flow between the thin tube and the through tube through the connector, and flow inside the thin tube, ensuring the accuracy and reliability of its multi-channel flow.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0026] Please see Figure 1 - Figure 4 The energy-saving gasification burner head based on the return air furnace in this embodiment includes a support cylinder 1 and a through pipe 2 built into the support cylinder 1. The feature is that a thin pipe 3 is built into the through pipe 2, the thin pipe 3 penetrates the support cylinder 1, and the through pipe 2 extends out of the support cylinder 1 from its top.

[0027] A connecting cylinder 102 is provided below the support cylinder 1, and a positioning ring 301 is provided below the thin tube 3. The thin tube 3 passes through the connecting cylinder 102 and is inserted into the inside of the through tube 2. The positioning ring 301 is located on the lower end face of the connecting cylinder 102.

[0028] After the support cylinder 1, through pipe 2, and thin pipe 3 are assembled, this device can be connected to different models of heating stoves on the market to replace the existing coal stoves and achieve high-efficiency heat transfer.

[0029] By installing the through pipe 2 inside the support cylinder 1, the thin pipe 3 is simultaneously inserted into the support cylinder 1 and the through pipe 2, and the thin pipe 3 is fixed on the connecting cylinder 102, so that the support cylinder 1, the through pipe 2, and the thin pipe 3 are used as a whole, so that a stable flow guiding space is formed inside and outside the through pipe 2, providing a flow channel for the flow of heat.

[0030] Under the flow inside the thin tube 3, the heat is transferred between the inner wall of the through tube 2 and the outer side of the thin tube 3, and the heat is transferred between the outer side of the through tube 2 and the inner wall of the support cylinder 1. After the support cylinder 1, through tube 2, and thin tube 3 are assembled, they provide multi-layer flow control support while allowing heat to flow between multiple spaces. This creates a complementary heating and heat preservation effect between adjacent spaces, improving the heat flow while preventing rapid heat loss, thereby improving the heat conversion efficiency of the device during use.

[0031] The support cylinder 1 is cylindrical in shape, and a through hole 104 is provided through the inner wall of the cylinder. The through hole 104 extends to the outside of the support cylinder 1, and the thin tube 3 is inserted through the through hole 104.

[0032] A side ring 101 is fixedly fitted on the side of the support cylinder 1 away from the connecting cylinder 102. The side ring 101 is larger than the support cylinder 1.

[0033] The connecting cylinder 102 has a through hole of the same specification as the through hole 104 inside. A connector 103 is installed on the outer side of the connecting cylinder 102, and the connector 103 communicates with the inside of the connecting cylinder 102.

[0034] With the heat temporarily stored and buffered by the inner cylinder of the support cylinder 1, it provides heat insulation support for the thin tube 3 and the through tube 2 located inside it. Under the connection structure formed by the side ring 101 and the support cylinder 1, the heat of this part is continuously and stably maintained. With the connection between the connecting cylinder 102 and the connector 103, and the connection between the connecting cylinder 102 and the positioning ring 301, the heat can flow between the thin tube 3 and the through tube 2 through the connector 103, and flow through the inside of the thin tube 3, ensuring the accuracy and reliability of its multi-channel flow.

[0035] Several conduits 201 are installed on the lower half of the outer side of the tube 2. The conduits 201 are evenly distributed in a ring on the outer side of the tube 2, and the conduits 201 are connected to the inside of the tube 2.

[0036] Several guide holes 202 are provided through the outside of the tube 2, and the guide holes 202 extend into the inside of the tube 2. A cone-shaped head 203 is installed at the upper end of the tube 2, and the upper edge of the cone head 203 is rounded.

[0037] Under the guidance of multiple outer conduits 201, the heat inside the pipe 2 can flow into the support cylinder 1 and then outward, increasing the heat flow path and allowing the heat to play a full role in its flow path. Thus, before its heat energy is exhausted, it continuously provides heating support for the support cylinder 1 and the pipe 2, making the heat utilization more complete and keeping the device in a heating state for a longer period of time, thereby improving its efficiency.

[0038] The conical shape of the conical head 203 restricts the flow of heat, causing a short-distance confinement. This constricts and compresses the heat flow, increasing its flow time within the pipe 2. Under this continuous consolidation and compression, the heat flows outward through the guide hole 202, allowing it to exit the pipe 2 in multiple directions. This enhances the multidirectional nature of the heat flow and improves the uniformity and comprehensiveness of the heating process.

[0039] The connection between the conduit 201 and the through pipe 2 is welded; the through pipe 2 is welded to the inner wall of the support cylinder 1; the through pipe 2 is welded to the conical head 203; the thin tube 3 is welded to the positioning ring 301; and the positioning ring 301 is welded to the connecting cylinder 102.

[0040] By welding the connections between the multiple components of the device, it is easy to quickly connect and fix them without creating too many connection points, allowing it to be installed and used as a whole, thus improving the convenience of its connection process.

[0041] The installation method, connection method, or setting method disclosed in this embodiment are all common mechanical connections.

[0042] Any connection method that can achieve its beneficial effect can be implemented. In addition, all electrical components in this embodiment are electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing public power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
