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.
[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0031] Please see Figure 1-4 As shown, this utility model is a gas monitoring device for a calcium carbide furnace, comprising:
[0032] The detector 100 has a gas sampling pipe 110 fixedly installed on its top. A gas sampling valve 120 is fixedly connected to the end of the gas sampling pipe 110. When 120 is opened, the gas in the flue gas pipe of the calcium carbide furnace is collected and enters the detector through 110.
[0033] The gas processing mechanism includes an outlet pipe 210, a purification component 220, a gas collecting pipe 230, a gas collecting valve 240, a gas collecting tank 250, an exhaust pipe 260, and an exhaust valve 270.
[0034] The gas outlet pipe 210 is fixed to the side of the detector 100, the purification component 220 is fixed to the other end of the gas outlet pipe 210, the gas collection pipe 230 is fixed to the other side of the purification component 220, the gas collection valve 240 is fixed to the other end of the gas collection pipe 230, the gas collection tank 250 is fixed to the other side of the gas collection valve 240, the exhaust pipe 260 is fixed to the other end of the gas collection tank 250, and the exhaust valve 270 is fixed to the other end of the exhaust pipe 260. The gas detected by the detector enters the purification component 220 through the gas outlet pipe 210. After being purified by the purification component 220, the toxic gas is adsorbed, and the remaining combustible gas enters the gas collection tank 250 through the gas collection pipe 230. The combustible gas is collected in the gas collection tank 250. When the sealed plate 225 is full of gas, the gas is extracted from the exhaust pipe 260 by opening the exhaust valve 270.
[0035] The purification component 220 includes a housing 221, a filter plate 222, an inlet 223, and a partition 224;
[0036] The outer shell 221 is fixed to the other end of the gas outlet pipe 210. There are three inlets 223, which are equally spaced on the top surface of the outer shell 221. There are two partitions 224, which are equally spaced and fixed in the inner cavity of the outer shell 221. There are three filter plates 222, which are respectively inserted into the three inlets 223. The filter plates 222 are aligned with the inlets 223 and inserted into the outer shell 221. After the gas enters the outer shell 221 through the gas outlet pipe 210, it passes through the three layers of filter plates 222 to adsorb the toxic gas.
[0037] A bracket 251 is fixed at the bottom of the gas collection tank 250, and a sealing plate 225 is fixed on the top surface of the filter plate 222. A handle 226 is fixed on the top surface of the sealing plate 225. Pulling the handle 226 moves the sealing plate 225, and the sealing plate 225 moves the filter plate 222 into and out of the insertion port 223 for easy replacement.
[0038] The size of the sealing plate 225 is larger than the opening size of the inlet 223 to prevent gas from leaking from the inlet 223. The two partitions 224 divide the interior of the outer shell 221 into three chambers. The three filter plates 222 pass through the corresponding inlet 223 and are inserted into the corresponding chambers.
[0039] Working principle: The gas detected by the detector enters the outer shell 221 through the gas outlet pipe 210. After entering the outer shell 221 through the gas outlet pipe 210, the gas passes through three layers of filter plates 222 to adsorb the toxic gas. When the filter plates 222 need to be replaced, the handle 226 is pulled to move the sealing plate 225. The sealing plate 225 moves the filter plates 222 to insert and pull out of the insertion port 223. The remaining combustible gas enters the gas collection tank 250 through the gas collection pipe 230 and is collected in the gas collection tank 250. When the sealing plate 225 is full of gas, the gas is extracted from the exhaust pipe 260 by opening the exhaust valve 270.
[0040] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes:
[0041] Alarm mechanism 300 includes a round tube 310, a round plate 320, a round cylinder 330, a spring 340, a pull rod 350, a sliding column 360, and a warning sign 370;
[0042] A circular tube 310 is fixedly connected to the side wall of an exhaust pipe 260. A circular plate 320 is slidably connected inside the circular tube 310. A cylinder 330 is fixedly connected to the top of the circular plate 320, with the other end of the cylinder 330 passing through the top of the circular tube 310. A spring 340 is fixedly connected at both ends to the top of the circular plate 320 and the top of the circular tube 310, respectively, with the cylinder 330 passing through the spring 340. One end of a pull rod 350 is rotatably connected to the end of the cylinder 330. A sliding column 360 is rotatably connected to the other end of the pull rod 350. A warning sign 370 is rotatably connected to the side wall of the circular tube 310. A groove 371 is provided on the surface of the warning sign 370, and the sliding column 360 is slidably connected within the groove 371. When… After the gas collection tank 250 is full, the gas pressure inside the gas collection tank 250 increases, causing the circular plate 320 to slide upward inside the circular tube 310. The upward sliding of the circular tube 310 causes the cylindrical column 330 to slide upward, compressing the spring 340 at the same time. The upward sliding of the cylindrical column 330 causes one end of the pull rod 350 to rotate and move upward. The upward movement of one end of the pull rod 350 causes the other end of the pull rod 350 to move upward, thereby causing the sliding column 360 to move upward. The upward movement of the sliding column 360 causes the sliding column 360 to slide in the sliding groove 371, while simultaneously causing one end of the warning sign 370 to lift up, making the warning sign 370 vertical to indicate to the staff that the gas collection tank 250 is full of gas, thus preventing the gas collection tank 250 from exploding due to excessive pressure.
[0043] Two square columns 331 are symmetrically arranged on the top of the cylindrical column 330. A connecting column 332 is fixedly connected between the two square columns 331. Rotary tubes 351 are fixed at both ends of the pull rod 350. One end of the rotary tube 351 is rotatably connected to the connecting column 332. A second rotating groove 361 is opened at the end of the sliding column 360. The other end of the rotary tube 351 is rotatably connected in the second rotating groove 361. One end of the rotary tube 351 rotates around the connecting column 332. The other end of the rotary tube 351 rotates in the second rotating groove 361.
[0044] A connecting plate 311 is fixedly installed on the upper end of the side wall of the round tube 310. A first rotating groove 312 is opened on the side wall of the connecting plate 311. The end of the sign 370 is rotatably connected in the first rotating groove 312. When one end of the sign 370 is lifted, the other end of the sign 370 rotates in the first rotating groove 312.
[0045] Working principle: When the gas collection tank 250 is full, the gas pressure inside the gas collection tank 250 increases, causing the circular plate 320 to slide upward in the circular tube 310. The upward sliding of the circular tube 310 drives the cylindrical column 330 to slide upward, compressing the spring 340 at the same time. The upward sliding of the cylindrical column 330 drives the square column 331 and the connecting column 332 to move upward. The upward movement of the square column 331 and the connecting column 332 drives one end of the rotating tube 351 to rotate and move upward. The upward movement of one end of the pull rod 350 drives the other end of the pull rod 350 to move upward and rotate in the second rotating groove 361, thereby driving the sliding column 360 to move upward. The upward movement of the sliding column 360 causes the sliding column 360 to slide in the sliding groove 371, while driving one end of the warning sign 370 to lift up, causing the other end of the warning sign 370 to rotate in the first rotating groove 312, so that the warning sign 370 is vertical, indicating to the staff that the gas collection tank 250 is full of gas, thus preventing the gas collection tank 250 from exploding due to excessive pressure.
