[0011] According to the technical solution provided in the embodiments of this application, the air intake structure includes a first air intake pipe, which extends along the first direction, with one end penetrating the first sidewall and extending into the interior of the furnace body. The top portion of the first air intake pipe located inside the furnace body is provided with a plurality of first air outlet holes evenly distributed along the first direction.

[0012] According to the technical solution provided in the embodiments of this application, the air intake structure further includes a second air intake pipe, which is disposed inside the furnace body and coaxially sleeved on the first air intake pipe. The bottom of the second air intake pipe is evenly provided with a plurality of second air outlet holes along the first direction.

[0013] According to the technical solution provided in the embodiments of this application, the gas equalization structure includes a flow equalization plate, which is a rectangular structure and adapted to the furnace body. The flow equalization plate is disposed inside the furnace body through an overlapping structure. A plurality of flow equalization holes are evenly opened on the flow equalization plate for equalizing the flow of the natural gas.

[0014] According to the technical solution provided in the embodiments of this application, the gas equalization structure further includes a plurality of screens arranged along the second direction at the top of the flow equalization plate. The screens are rectangular structures that are adapted to the furnace body and are used to equalize the flow of the natural gas. The second direction is perpendicular to the first direction.

[0015] According to the technical solution provided in the embodiments of this application, a support frame is provided at the top of the screen, which is a rectangular frame structure. A cavity is formed inside the support frame. The honeycomb panel is disposed at the top of the support frame, and the circumferential edge of the honeycomb panel is sealed with the inner wall of the furnace through a sealing structure.

[0030] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0031] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] Example 1

[0033] Please refer to Figure 1 The schematic diagram shown illustrates the structure of the gas heating furnace for a diamond wire drawing machine. The gas heating furnace includes a furnace frame 10 and a furnace body 1. The furnace frame 10 has a rectangular structure with a groove 11 at its top, forming a first space. The furnace body 1 is movably positioned within this first space along a first direction. Figure 2 Mid-horizontal direction;

[0034] like Figures 5 to 7 As shown, the furnace body 1 has a rectangular structure, a first side wall perpendicular to the first direction, and an open top.

[0035] The air intake structure includes a first air intake pipe 3, the length of which extends along a first direction, and one end of the first air intake pipe 3 extends through the first side wall into the furnace body 1 and is fixedly connected to the inner wall of the furnace body 1 opposite to the first side wall.

[0036] Correspondingly, a through hole is provided on the first side wall along the first direction, and the outer wall of the first air intake pipe 3 and the inner wall of the through hole are fixedly connected;

[0037] The air intake structure also includes a second air intake pipe 5, which is located inside the furnace body 1 and extends along the first direction. Both ends of the second air intake pipe 5 are fixedly connected to the inner wall of the first side wall of the furnace body 1 and the inner wall opposite to the first side wall, respectively. The diameter of the second air intake pipe 5 is larger than the diameter of the first air intake pipe 3. The second air intake pipe 5 is sleeved on the outer wall of the part of the first air intake pipe 3 located inside the furnace body 1, and there is a gap between the second air intake pipe 5 and the first air intake pipe 3 to form an air passage space.

[0038] The first air inlet pipe 3 is located inside the furnace body 1, and a plurality of first air outlet holes 4 are evenly opened at the top along the first direction. The second air inlet pipe 5 has a plurality of second air outlet holes 19 evenly opened at the bottom along the first direction.

[0039] Thus, by supplying natural gas to the first air inlet pipe 3, the natural gas enters the gas passage space through the first air outlet 4, and then is transported into the furnace body 1 through the second air outlet 19.

[0040] The gas equalization structure is set inside the furnace body 1 and above the gas inlet structure to uniformly disperse the natural gas;

[0041] Specifically, the gas equalization structure includes a flow equalization plate 6, which is a rectangular structure and is adapted to the furnace body 1. The flow equalization plate 6 is set inside the furnace body 1 through an overlapping structure, and several flow equalization holes 7 are evenly opened on the flow equalization plate 6.

[0042] Furthermore, a number of flow equalization holes 7 are distributed throughout the flow equalization plate 6. The flow equalization holes 7 can be selected with a diameter of 3mm. Through the flow equalization holes 7, natural gas can move upward.

[0043] Furthermore, the overlapping structure includes overlapping pieces. Overlapping pieces are provided at the included angles between two adjacent inner walls inside the furnace body 1. The flow equalization plate 6 is placed on the overlapping pieces, thereby achieving support for the four corners of the flow equalization plate 6, thus ensuring that the flow equalization plate 6 can be placed stably.

[0044] Furthermore, the gas equalization structure also includes a screen assembly, which comprises six layers of screens 8 arranged in a second direction. The screen assembly is located on top of the flow equalization plate 6, and the screens 8 have a rectangular structure that is compatible with the furnace body 1; the second direction is... Figure 2 The first direction is vertical, and the second direction is perpendicular to the first direction;

[0045] Optionally, the screen 8 is 120 mesh;

[0046] The screen assembly can re-equalize the natural gas passing through the flow equalization plate 6, ensuring that the natural gas is evenly distributed in the furnace body.

[0047] The top of the screen 8 is provided with a support frame 9, which is a rectangular frame structure, and the inside of the support frame 9 forms a cavity;

[0048] Furthermore, a honeycomb panel 2 is provided on the top of the support frame 9, and the circumferential edge of the honeycomb panel 2 is sealed with the inner wall of the furnace body 1 through a sealing structure;

[0049] Optionally, the honeycomb panel 2 is a ceramic honeycomb panel;

[0050] Optionally, the sealing structure is a mixture of refractory putty and industrial glass water to ensure a strong seal;

[0051] As a result, the natural gas, which is uniformly distributed by the gas equalization structure, continues to rise into the cavity, and then moves upward through the honeycomb plate 2 and is ignited. Thus, a combustion space is formed above the honeycomb plate 2, which can heat the diamond wire.

[0052] like Figures 1 to 4 As shown, the heating furnace frame 10 has a second side wall perpendicular to the first direction, and an avoidance groove 12 is provided on the second side wall to avoid the first air inlet pipe 3.

[0053] Furthermore, the heating furnace frame 10 also has a third side wall and a fourth side wall opposite to each other in a third direction, and a first connecting plate 13 is movably disposed on both the third side wall and the fourth side wall; the third direction is... Figure 3 In the horizontal direction, the third direction is perpendicular to the first direction and perpendicular to the second direction;

[0054] Furthermore, two connecting holes 15 are provided at the bottom of both the third and fourth sidewalls, and the connecting holes 15 can be screw holes;

[0055] Furthermore, the first connecting plate 13 is provided with two first sliding grooves 14 corresponding to the two connecting holes 15. The length of the first sliding groove 14 extends along the second direction, and the connector 16 passes through the first sliding groove 14 and extends into the connecting hole 15; the connector 16 can be a bolt.

[0056] Therefore, by twisting the connector 16 to loosen it, the position of the heating furnace frame 10 in the second direction can be adjusted, and then the connector 16 can be tightened to fix the position, thereby realizing the position adjustment of the furnace body 1.

[0057] Two first connecting plates 13 are connected to a second connecting plate 17 at one end near the second side wall. Two second sliding grooves 18 are provided on the second connecting plate 17. Both second sliding grooves 18 extend along the third direction and are arranged in the third direction. They are used to adjust the position of the heating furnace frame 10 in the third direction when connected to the external structure, thereby adjusting the position of the furnace body 1.

[0058] It should be noted that the first air intake pipe 3 is equipped with a valve.

[0059] It should be noted that a reinforcing member is provided between the first connecting plate 13 and the second connecting plate 17 to enhance the connection strength.

[0060] Working principle: Natural gas is supplied to the first air inlet pipe 3. The natural gas enters the gas passage space through the first air outlet 4, and then is supplied to the inner wall of the bottom of the furnace body 1 through the second air outlet 19. The natural gas then rises. This structure can prevent the natural gas from blowing directly into the flow equalization plate 6, providing the prerequisite for subsequent flow equalization. The rising natural gas passes through the flow equalization plate 6 and the screen assembly in sequence and is fully evenly distributed, ensuring that the natural gas can be evenly distributed in the furnace body 1. Then, the natural gas passes through the honeycomb plate 2 and can be evenly distributed above the honeycomb plate 2. Ignition above the honeycomb plate 2 can heat the diamond wire above the honeycomb plate 2.

[0061] By setting up honeycomb panel 2, when the diamond wire breaks, it will fall onto honeycomb panel 2. The design of using natural gas heating through this device completely avoids the risk of the diamond wire coming into contact with the heating wire compared to the existing technology that uses heating wire auxiliary heating. At the same time, it does not require a long preheating time, and the valve can be closed after production, saving energy.

[0062] Furthermore, the furnace body 1 can be adjusted in the first, second, and third directions according to the actual production situation, which improves its applicability. At the same time, the natural gas supply can be adjusted according to the actual production situation through valves, thereby adjusting the firepower, which provides greater flexibility.

[0063] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
