Technical Field
[0001] This utility model relates to the field of hydrogen chloride synthesis furnace technology, specifically a mixing device for a hydrogen chloride synthesis furnace. Background Technology
[0002] The hydrogen chloride synthesis furnace mixes hydrogen and chlorine gases in a reaction vessel, then synthesizes hydrochloric acid gas. Before entering the furnace, the hydrogen and chlorine gases pass through a graphite guide pipe. This guide pipe connects to the furnace's inlet pipe, typically via flanges. However, these connections are susceptible to corrosion and rust over time, leading to leaks. This leakage not only affects the concentration of the mixture during transport but also impacts the surrounding environment. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a mixing device for a hydrogen chloride synthesis furnace, comprising a furnace body, an inlet pipe connected to the upper and lower left side of the furnace body, an inner cover, a partition plate, and a spiral pipe respectively disposed inside the furnace body, and further comprising:
[0005] The cooling structure located on the right side of the furnace body has a sealing sleeve movably connected to the surface of the air inlet pipe, and a first air bladder is embedded inside the sealing sleeve.
[0006] A fixing plate is fixed on the left side of the furnace body. A screw is movably connected inside the fixing plate. One end of the screw is rotatably connected to the left side of the furnace body. The other end of the screw is fixed to one side of the crank handle. A screw sleeve is threaded onto the surface of the screw. Vertical plates are fixed on both the upper and lower sides of the screw sleeve. The other end of the vertical plates is fixed to one side of the sealing sleeve.
[0007] The outer shell is fixed to the surface of the fixing plate, and a second airbag is provided inside the outer shell. The bottom of the second airbag is connected to an air inlet pipe, and the right side of the second airbag is connected to a hose. The other end of the hose is connected to a fixing pipe. Both ends of the fixing pipe pass through a sealing sleeve and are connected to the first airbag.
[0008] Preferably, the cooling structure includes a cooling box fixed to the right side of the furnace body, a water pump installed on the top of the cooling box, a liquid outlet pipe connected to the discharge end of the water pump, and a nozzle connected to the other end of the liquid outlet pipe.
[0009] Preferably, the inner side of the fixing plate is provided with sliding grooves at both the front and rear sides, and the front and rear sides of the screw sleeve are fixedly connected with sliders, the other end of the sliders being slidably connected to the inside of the sliding grooves.

[0022] Please see Figure 1-4 As shown, a mixing device for a hydrogen chloride synthesis furnace includes a furnace body 1. An inlet pipe 2 is connected to both the upper and lower sides of the left side of the furnace body 1. An inner cover 3 is installed inside the furnace body 1, and a partition plate 4 is fixed above the inner cover 3 and to the inner wall of the furnace body 1. A spiral pipe 5 is connected to the top of the partition plate 4, and the other end of the spiral pipe 5 is connected to the discharge end of the furnace body 1. A cooling structure 6 is provided on the right side of the furnace body 1. A sealing sleeve 8 is movably connected to the surface of the inlet pipe 2, and a first air bladder 9 is embedded inside the sealing sleeve 8. A fixing plate 10 is fixedly connected to the left side of the furnace body 1. A screw 12 is movably connected inside the fixing plate 10, and one end of the screw 12 is rotatably connected to the left side of the furnace body 1. The other end of the screw 12 is fixed to one side of a crank handle 11. A threaded sleeve 13 is threadedly connected to the surface of the screw 12, and the upper and lower sides of the threaded sleeve 13 are... Each is fixed with a vertical plate 14, and the other end of the vertical plate 14 is fixed to one side of the sealing sleeve 8. The surface of the fixing plate 10 is fixed with a shell 15, and the inside of the shell 15 is provided with a second airbag 16. The bottom of the second airbag 16 is connected to an air inlet pipe 21, and the right side of the second airbag 16 is connected to a hose 17, and the other end of the hose 17 is connected to a fixing pipe 18. The surface of the air inlet pipe 21 is provided with a one-way valve 22, and the surface of the hose 17 is provided with a one-way valve 23, so that the air inlet pipe 21 can only take in air, and the hose 17 can only take out air. The two ends of the fixing pipe 18 pass through the sealing sleeve 8 and are connected to the first airbag 9. The surface of the fixing pipe 18 is provided with a valve 24, so that when the seal between the air inlet pipe 21 and the external pipe is removed, the valve 24 can be opened to exhaust air, so that the first airbag 9 can be contracted.
[0023] The cooling structure 6 includes a cooling tank 61, a water pump 62, a liquid outlet pipe 63, and a nozzle 64. The cooling tank 61 is fixed on the right side of the furnace body 1, and the water pump 62 is fixed on the top of the cooling tank 61. The suction end of the water pump 62 is connected to the cooling tank 61, and the discharge end of the water pump 62 is connected to one end of the liquid outlet pipe 63. The other end of the liquid outlet pipe 63 extends into the interior of the furnace body 1 and is connected to the nozzle 64. Thus, when cooling is performed, the water pump 62 can be started to draw the coolant inside the cooling tank 61 and then deliver it to the nozzle 64 through the liquid outlet pipe 63, thereby spraying it onto the surface of the spiral pipe 5 for cooling.
[0024] The front and rear sides of the inner side of the fixing plate 10 are provided with sliding grooves 19. The front and rear sides of the screw sleeve 13 are fixedly connected with sliders 20.

[0026] It is worth noting that the technical features proposed in this technical solution should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be selected using conventional methods in the field. This technical solution will not elaborate further.
[0027] Working principle: In use, the external pipe can be connected to the inlet pipe 2. After the connection is completed, the crank handle 11 can be turned to drive the screw 12 to rotate. At the same time, the screw sleeve 13, the vertical plate 14 and the sealing sleeve 8 will move to the left on the surface of the inlet pipe 2, so that the sealing sleeve 8 is located on the surface of the connection between the inlet pipe 2 and the external pipe. Then, the second air bag 16 is pressed, and the gas is delivered into the interior of the first air bag 9 through the hose 17 and the fixed pipe 18, causing the first air bag 9 to expand, thereby sealing the connection between the inlet pipe 2 and the external pipe. Then, hydrogen and chlorine will enter the interior of the furnace body 1 through the upper and lower inlet pipes 2 respectively. Subsequently, the gas will float upward through the inner cover 3. At this time, hydrogen and chlorine will be initially mixed below the partition plate 4. The mixed gas will be mixed around through the spiral pipe 5. During the mixing process, the surface of the spiral pipe 5 can be sprayed and cooled by the cooling structure 6, thereby ensuring that the generated hydrogen chloride gas can be stably output.
