Description

Technical Field

[0001] This invention relates to the field of sheet metal cutting equipment technology, and in particular to a combustible gas generating device and cutting equipment. Background Technology

[0002] In the steel structure processing industry, high efficiency, low cost, and low pollution are required in the processing. Gas cutting of sheet metal is widely used in this industry. Currently, the most common type of gas cutting machine used in sheet metal processing is the acetylene cutting machine. This machine mainly includes a cutting torch, compressed oxygen and acetylene storage tanks, a manually controlled throttle valve, and an ignition cutting device.

[0003] However, the aforementioned acetylene cutting machines have a narrow range of applications. While existing acetylene cutting machines can meet the cutting needs of most sheet materials, acetylene has a low calorific value, resulting in low cutting efficiency for thicker sheets. Furthermore, acetylene fuel is a gas at room temperature and pressure, making it unsuitable for transportation and storage. Currently, most acetylene gas used in acetylene cutting machines is bottled acetylene, which poses significant safety hazards during frequent transportation. In addition, acetylene is expensive and has a relatively low calorific value, making it uneconomical.

[0004] Therefore, there is an urgent need for a combustible gas generating device and cutting equipment to solve the above problems. Summary of the Invention

[0039] Figure 1 This diagram shows a structural schematic of a combustible gas generating device provided in an embodiment of the present invention. Figure 2 A cross-sectional view of a combustible gas generating device provided in an embodiment of the present invention is shown. (Refer to...) Figure 1 and Figure 2 This embodiment provides a combustible gas generating device. The combustible gas generating device includes a heater 100, an evaporator 200, a filter 300, and a generator cover 500.

[0040] Specifically, the heater 100 includes a heater housing 110, the interior of which is hollow to form a heating chamber 120, which is configured to hold a heat-conducting liquid. The evaporator 200 includes an evaporator body 210, which is inserted into the heating chamber 120. The interior of the evaporator body 210 is hollow to form an evaporation chamber 220, which is configured to hold pentane liquid, which vaporizes in the evaporation chamber 220. In other words, by heating the heater housing 110, the heat-conducting liquid in the heating chamber 120 can uniformly heat the evaporator body 210; the evaporation chamber 220 provides an evaporation space for the low-boiling-point pentane liquid.

[0041] More specifically, the heater 100 further includes a heating component 140, which is fixedly connected to the heater housing 110 and configured to heat the heat-conducting liquid. In this embodiment, the heating component 140 is a heating mica, which is ring-shaped around the heater housing 110 and connected to a power source. When the heating mica is energized, it generates heat, thereby heating the heater housing 110. Through the heat conduction of the heat-conducting liquid in the heating chamber 120, the evaporator 200 is then uniformly heated.

[0042] More specifically, the filter 300 is connected to the heater housing 110, the evaporator 200 is housed in the heating chamber 120 and the filter 300, and the filter 300 is configured to filter pentane gas. The filter 300 can filter the pentane gas formed by evaporation, thereby improving the purity of the pentane gas.

[0043] Continue to refer to Figure 1 and Figure 2The filter 300 includes a filter housing 310 and a filter mechanism 320. The filter housing 310 is hollow, forming a filter chamber. The filter mechanism 320 is installed in the filter chamber, located downstream of the evaporator 200, and configured to filter the pentane gas. In this embodiment, the filter mechanism 320 includes a demister and a filter element. A support is placed above the evaporator chamber 220, and a demister is placed on the upper side of the support. The demister is configured to remove residual pentane liquid, and the filter element is configured to further purify the pentane gas.

[0044] Preferably, the filter housing 310 is provided with a liquid inlet, which is connected to a pentane liquid source. A shut-off valve is provided at the liquid inlet, through which the pentane liquid enters the evaporation chamber 220.

[0045] Specifically, the filter 300 further includes a lower filter flange 330, which is fixedly connected to the bottom of the filter housing 310; the heater 100 further includes an upper heater flange 130, which is fixedly connected to the top of the heater housing 110; the lower filter flange 330 can be reliably connected to the upper heater flange 130. That is, the upper periphery of the evaporator 200 is fixedly connected to the inner wall of the filter chamber by welding, realizing a reliable connection between the evaporator 200 and the filter 300.

[0046] Figure 3 Show Figure 2 A magnified view of the structure marked A in the middle, see reference. Figure 2 and Figure 3 Preferably, the combustible gas generating device further includes a first sealing ring 400, which is sandwiched between the lower flange 330 of the filter and the upper flange 130 of the heater. Figure 3 As shown, the heater upper flange 130 has an annular first sealing groove on the side facing the filter lower flange 330, and the geometric center of the first sealing groove coincides with the geometric center of the heater upper flange 130. The first sealing ring 400 is embedded in the first sealing groove. This arrangement reliably seals the gap between the heater upper flange 130 and the filter lower flange 330, preventing pentane gas leakage. In this embodiment, the first sealing ring 400 is made of rubber.

[0047] Continue to refer to Figure 2 In this embodiment, the generator cover 500 is connected to the filter housing 310. The internal space of the generator cover 500 is connected to the filter chamber. A connector 510 is provided on the top of the generator cover 500. The connector 510 is connected to the internal space of the generator cover 500 and is configured to connect to the cutting torch.

[0048] Specifically, a generator flange 530 is fixedly connected to the bottom of the generator cover 500 body; a filter upper flange 340 is fixedly connected to the top of the filter housing 310. The generator flange 530 is located and connected to the filter upper flange 340.

[0049] More specifically, the combustible gas generating device also includes a second sealing ring 600. The second sealing ring 600 is sandwiched between the generator flange 530 and the filter upper flange 340. The filter upper flange 340 has an annular second sealing groove on its side facing the generator flange 530, and the geometric center of the second sealing groove coincides with the geometric center of the filter upper flange 340. The second sealing ring 600 is embedded in the second sealing groove. Through the above arrangement, the gap between the generator flange 530 and the filter upper flange 340 can be reliably sealed, preventing pentane gas leakage. In this embodiment, the second sealing ring 600 is also made of rubber.

[0050] More specifically, the generator cover 500 has a vacuum suction port 520, which is configured to connect the internal space of the generator cover 500 to a vacuum pump. The vacuum pump is configured to evacuate air from the combustible gas generator before the heating assembly 140 operates, thereby maintaining a vacuum inside the combustible gas generator and preventing an explosion after the pentane liquid evaporates and forms gas.

[0051] Figure 4 A schematic diagram of the cutting device provided in an embodiment of the present invention is shown. (Refer to...) Figure 4 This embodiment also provides a cutting device. The cutting device includes a liquid storage tank 10 and an electrical control box 20, and also includes a combustible gas generating device provided in this embodiment. The liquid storage tank 10 is connected to the evaporation chamber 220 and is configured to store pentane liquid as a pentane liquid source. The electrical control box 20 is electrically connected to the heating component 140 of the heater 100 and is configured to control the opening and closing of the heating component 140.

[0052] Specifically, the cutting equipment also includes a mobile trolley 30, on which the liquid storage tank 10, the electrical control box 20, and the combustible gas generator are all mounted. The heater 100 also includes a bottom flange 150, which is fixed to the bottom of the heater housing 110 and has multiple evenly spaced mounting holes 151. These mounting holes 151 are configured to insert mounting bolts, which are then used to mount the bottom flange 150 to the target position. This configuration facilitates the transfer of the entire cutting equipment.

[0053] More specifically, the combustible gas generating device provided in this embodiment further includes a thermally conductive liquid level gauge and a liquid fuel level gauge. The thermally conductive liquid level gauge is installed on the inner wall of the heating chamber 120 and is configured to sense the level of the thermally conductive liquid. The liquid fuel level gauge is installed on the inner wall of the evaporation chamber 220 and is configured to sense the level of the pentane liquid. The thermally conductive liquid level gauge and the liquid fuel level gauge are respectively communicatively connected to the electrical control box 20, which is capable of indicating the levels of the thermally conductive liquid and the pentane liquid. The electrical control box 20 is prior art, and its structure and principle will not be described in detail here. Optionally, the electrical control box 20 can also indicate the internal vacuum degree of the combustible gas generating device before heating and the pressure of the pentane gas output at connector 510.
