Abstract
Description
Technical Field
[0001] This utility model relates to the field of gas flow technology for static furnaces, and specifically to an automatic flow control device for static furnaces. Background Technology
[0002] Currently, during the firing process of the settling furnace, the heating is achieved by manually controlling the gas supply via valves. This results in unstable gas pressure and fluctuating gas flow, wasting approximately 1000 cubic meters of gas. Furthermore, overheating can damage the furnace, and the firing time is extended by 40-60 minutes per furnace, leading to low production efficiency. Therefore, an automatic flow control device for settling furnaces is urgently needed to solve these problems. Utility Model Content
[0003] To address the technical problems of relying on manual valve control for gas supply to the settling furnace, which leads to unstable gas pressure, fluctuating gas flow, overheating and potential damage, and prolonged firing time, this invention provides an automatic flow control device for the settling furnace. This device ensures stable gas pressure and uniform, quantitative gas delivery to the furnace, preventing overheating and prolonged firing time, and effectively improving the furnace's production efficiency.
[0004] This utility model provides an automatic flow control device for a settling furnace, including a gas box and multiple pipe assemblies. Each pipe assembly includes a gas outlet pipe, an automatic gas outlet valve, and a first flow meter connected to the gas outlet pipe. The gas box is equipped with a pressure regulating component and multiple gas outlet ports, the same number as the pipe assemblies. Each gas outlet port is detachably connected to one end or a sealing head of the gas outlet pipe, and the other end of the gas outlet pipe is detachably connected to the settling furnace. The gas box stores fuel gas. The pressure regulating component can initially adjust the pressure and flow rate of the fuel gas entering the gas box to maintain a stable fuel gas pressure. The fuel gas then enters the settling furnace through the gas outlet pipes.
[0005] Furthermore, the pressure regulating assembly includes an intake pipe and an automatic intake valve, a filter, a pressure regulator, and a second flow meter connected sequentially to the intake pipe. The gas tank is equipped with an intake port, and both ends of the intake pipe are fixedly connected to the intake port and the gas source tank, respectively. The automatic intake valve automatically controls the flow of gas into the gas tank. The filter removes impurities from the gas, ensuring its purity. The pressure regulator regulates the gas pressure, stabilizing it. The second flow meter displays the gas flow rate. Gas from the gas source tank enters the gas tank evenly and quantitatively, and the gas pressure remains stable.
[0006] Furthermore, the automatic flow control device for the stationary furnace also includes a frame. The bottom of the frame is equipped with rollers and a support plate, with the support plate positioned above the rollers. The gas box is fixedly connected to the support plate. The frame supports and secures the gas box. Movement of the rollers on the frame moves the frame and the gas box, allowing for easier and more convenient supply of gas to multiple stationary furnaces by changing the position of the gas box.
[0007] Furthermore, multiple support frames are detachably installed on the frame corresponding to the air outlet, and each support frame is equipped with an arc-shaped bracket, with the air outlet located on the arc-shaped bracket. When the air outlet is not in use, the support frame can be detached from the frame, meaning the support frame can be used in conjunction with the air outlet.
[0008] Furthermore, the frame is provided with multiple first locking plates, and each support frame is provided with a second locking plate. The first and second locking plates are fixedly connected by bolts. The fixed connection of the first and second locking plates thereby fixes the support frame to the frame. At this time, the arc-shaped bracket on the support frame can support and fix the air outlet pipe.
[0009] Furthermore, the automatic flow control device for the static furnace also includes a display screen, which is mounted on the frame and located to the side of the gas tank. The gas tank is also equipped with a gas sensor for detecting the concentration of gas outside the tank. The display screen is electrically connected to the automatic outlet valve, the first flow meter, the automatic inlet valve, the second flow meter, and the gas sensor. When there is a leak in the gas tank, and the gas sensor detects that the concentration of combustible gas outside the tank exceeds the standard, the gas sensor will trigger an alarm.
[0010] Furthermore, the static furnace is equipped with a gas outlet. Both the outer surface of the gas outlet and the outer surface of the gas pipe are provided with external threads. Both ends of the gas outlet and the inner surface of the sealing head are provided with internal threads matching the external threads. The gas outlet is threadedly connected to one end of the gas outlet or the sealing head, and the other end of the gas outlet is threadedly connected to the gas inlet. The gas outlet is connected to the gas outlet or the sealing head as needed to meet gas intake or gas shut-off requirements.
[0011] Compared with the prior art, the present invention has the following technical effects:
[0012] This utility model discloses an automatic flow control device for a settling furnace. The gas tank stores natural gas, and a pressure regulating component initially adjusts the pressure and flow rate of the gas entering the tank to maintain stable pressure. The gas then enters the settling furnace through an outlet pipe. An automatic outlet valve and a first flow meter are installed on the outlet pipe. The automatic outlet valve automatically controls the gas flow into the settling furnace, and the first flow meter displays the gas flow rate. Ultimately, the gas enters the settling furnace evenly and quantitatively, preventing overheating and prolonged firing time, and effectively improving the furnace's production efficiency.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0023] like Figures 1-3As shown, an automatic flow control device for a settling furnace includes a gas box 1 and multiple pipe assemblies. Each pipe assembly includes a gas outlet pipe 2, an automatic gas outlet valve 21, and a first flow meter 22 connected to the gas outlet pipe 2. The gas box 1 is equipped with a pressure regulating component and multiple gas outlet ports 11, the same number as the pipe assemblies. Each gas outlet port 11 is detachably connected to one end of the gas outlet pipe 2 or a sealing head 5, and the other end of the gas outlet pipe 2 is detachably connected to the settling furnace. Because there are multiple settling furnaces in the work area, each requiring gas, the automatic flow control device can simultaneously supply gas to multiple settling furnaces. The same number of pipe assemblies are installed on the gas box 1 according to the number of settling furnaces. Specifically, the sealing head 5 is removed from the gas outlet port 11, and one end of the gas outlet pipe 2 is installed on the gas outlet port 11, while the other end of the gas outlet pipe 2 is installed on the settling furnace. When the gas outlet 11 is not in use, the sealing head 5 seals the gas outlet 11 to prevent gas from leaking from the gas outlet 11.
[0024] In this embodiment, the automatic flow control device operates as follows: Gas tank 1 stores natural gas. The pressure regulating component initially adjusts the pressure and flow rate of the gas entering tank 1 to maintain a stable gas pressure. The gas then enters the settling furnace through outlet pipe 2. Outlet pipe 2 is equipped with an automatic outlet valve 21 and a first flow meter 22. The automatic outlet valve 21 automatically controls the gas flow into the settling furnace, and the first flow meter 22 displays the gas flow rate. This ensures that the gas enters the settling furnace evenly and quantitatively, preventing overheating and prolonged firing time, thus effectively improving the furnace's production efficiency. Because different outlet pipes 2 connect to different settling furnaces, the gas flow rate can be set according to the requirements of each furnace. In this embodiment, the gas flow rate is set to 800 cubic meters.
[0025] The automatic flow control device in this embodiment ensures stable gas pressure, allowing the gas to enter the settling furnace evenly and quantitatively, thus preventing overheating and prolonged burning time, and effectively improving the production efficiency of the settling furnace.
[0026] In one possible implementation, the pressure regulating assembly includes an inlet pipe 3 and an automatic inlet valve 31, a filter 32, a pressure regulator 33, and a second flow meter 34 connected sequentially to the inlet pipe 3. The gas tank 1 is provided with an inlet port 12, and both ends of the inlet pipe 3 are fixedly connected to the inlet port 12 and the gas source tank, respectively. The outlet pipe 2 is provided with an automatic inlet valve 31, a filter 32, a pressure regulator 33, and a second flow meter 34. The automatic inlet valve 31 automatically controls the flow of gas into the gas tank 1. The filter 32 filters out impurities in the gas, ensuring gas purity. The pressure regulator 33 adjusts the gas pressure to stabilize it. The second flow meter 34 displays the gas flow rate. The gas in the gas source tank can enter the gas tank 1 evenly and quantitatively, and the gas pressure remains stable.
[0027] In one possible implementation, the automatic flow control device for the stationary furnace further includes a frame 4. The bottom of the frame 4 is equipped with rollers 41 and a support plate 42, with the support plate 42 positioned above the rollers 41. The gas box 1 is fixedly connected to the support plate 42. The frame 4 supports and fixes the gas box 1. Movement of the rollers 41 on the frame 4 can move the frame 4 and the gas box 1, allowing the gas box 1 to supply gas to multiple stationary furnaces more conveniently while changing its position.
[0028] In one possible implementation, multiple support frames 43 are detachably installed on the frame 4 at positions corresponding to the gas outlet 11. Each support frame 43 is equipped with an arc-shaped bracket 431, and the gas outlet 2 is located on the arc-shaped bracket 431. The arc-shaped bracket 431 can support and fix the gas outlet 2, ensuring that the gas outlet 2 remains stable when delivering gas, so as not to affect the uniformity of gas delivery. When the gas outlet 2 is not in use, the support frame 43 can be detached from the frame 4, that is, the support frame 43 is used in conjunction with the gas outlet 2.
[0029] In one possible implementation, the frame 4 is provided with a plurality of first locking plates 44, and each support frame 43 is provided with a second locking plate 432. The first locking plates 44 and the second locking plates 432 are fixedly connected by bolts. Specifically, both the first locking plates 44 and the second locking plates 432 are provided with locking holes, and the locking holes on the first locking plates 44 and the second locking plates 432 are fixedly connected by bolts. The fixed connection of the first locking plates 44 and the second locking plates 432 thereby fixes the support frame 43 to the frame 4, and at this time, the arc-shaped bracket 431 on the support frame 43 can support and fix the air outlet pipe 2.
[0030] In one possible implementation, the automatic flow control device for the static furnace also includes a display 7, which is mounted on the frame 4 and located to the side of the gas tank 1. The gas tank 1 is also equipped with a gas sensor 6 for detecting the concentration of gas outside the gas tank 1. The display 7 is electrically connected to the automatic outlet valve 21, the first flow meter 22, the automatic inlet valve 31, the second flow meter 34, and the gas sensor 6. The display 7 can show the opening and closing status of the automatic outlet valve 21 and the automatic inlet valve 31, and can also display the values of the first flow meter 22, the second flow meter 34, and the gas sensor 6, facilitating personnel to observe the working status of the automatic flow control device. When there is a leak in the gas tank 1, and the gas sensor 6 detects that the concentration of gas outside the gas tank 1 exceeds the standard, the gas sensor 6 will sound an alarm.
[0031] In one possible implementation, the stationary furnace is provided with a gas outlet. Both the outer surface of the gas outlet 11 and the outer surface of the gas pipe are provided with external threads. Both ends of the gas outlet 2 and the inner surface of the sealing head 5 are provided with internal threads that match the external threads. The gas outlet 11 is threadedly connected to one end of the gas outlet 2 or the sealing head 5 via external and internal threads. The other end of the gas outlet 2 is threadedly connected to the gas inlet via external and internal threads. In this embodiment, the gas outlet 11 is connected to the gas outlet 2 or the sealing head 5 as needed to meet gas intake or gas shut-off requirements.
[0032] The embodiments described above are merely preferred embodiments of this utility model and are only used to explain this utility model. They are not intended to limit the scope of implementation of this utility model. For those skilled in the art, other implementation methods can be easily made by substitution or modification based on the technical content disclosed in this specification.
