Description

Technical Field

[0001] The utility model belongs to the technical field of high-pressure reactors, and in particular relates to a novel side liquid discharge device for a high-pressure reactor. Background Art

[0002] After the reaction in the high-pressure reactor is finished, the liquid metal in it needs to be discharged. Since the reactor is in a state of high temperature and pressure, and there is corrosive liquid metal in the reactor, the use of ordinary drainage pipes will be prone to blockage and leakage. If the liquid metal is cooled into a whole piece of solid metal in the crucible after the reaction is finished and then taken out, the removal process is more laborious and easily causes damage to the refractory lining. Utility Model Content

[0003] In order to overcome the deficiencies of the above-mentioned technology, the purpose of the utility model is to provide a novel side liquid discharge device for a high-pressure reactor.

Since neither the refractory material nor the tungsten rod will be corroded by the liquid metal, the liquid metal can be blocked for a long time.

[0005] Furthermore, a hydraulic cylinder is provided on the side of the refractory material conduit away from the high-pressure reactor, a telescopic rod of the hydraulic cylinder is passed through the refractory material conduit, and an end of the telescopic rod is hinged to one end of the tungsten rod through a buckle.

[0006] Furthermore, the inner diameter of the end of the refractory material conduit away from the high-pressure reactor gradually decreases along the direction from the high-pressure reactor to the refractory material conduit, and the inner diameter of the end surface of the refractory material conduit away from the high-pressure reactor is smaller than the diameter of the tungsten rod.

[0007] Furthermore, the refractory material conduit is externally sheathed with a first steel pipe.

[0008] Furthermore, the refractory material drainage pipe is sheathed with a second steel pipe.

[0009] Furthermore, a gate valve is provided between the refractory drainage pipe and the collecting tube, the outlet of the gate valve is connected to the inlet of the collecting tube, the inlet of the gate valve is communicated with the refractory drainage pipe, and the gate valve is connected to the second steel pipe through a flange.

[0012] Figure 2 It is a structural schematic diagram of the coordination of a refractory conduit, a refractory drainage pipe and a gate valve. DETAILED DESCRIPTION

[0013] The utility model is described in detail below with reference to the accompanying drawings and specific embodiments.

[0014] like Figures 1 to 2 As shown, a novel side liquid discharge device of a high-pressure reactor comprises a collecting tube 4 and a refractory conduit 7, one end of the refractory conduit 7 is connected to the liquid metal outlet of the high-pressure reactor 1, a liquid metal discharge outlet is arranged in the middle of the refractory conduit 7 and the liquid metal discharge outlet is connected to the collecting tube 4 through a refractory drainage pipe 8, a tungsten rod 9 is penetrated in the refractory conduit 7 and can reciprocate along the axial direction of the refractory conduit 7, and the liquid metal outlet of the high-pressure reactor 1 can be blocked or opened by moving the tungsten rod 9, so that the liquid metal outlet of the high-pressure reactor 1 can be connected or disconnected with the liquid metal discharge outlet of the refractory conduit 7. Since neither the refractory material nor the tungsten rod will be corroded by the liquid metal, the liquid metal can be blocked for a long time.

[0015] A hydraulic cylinder 13 is provided on the side of the refractory material conduit 7 away from the high-pressure reactor 1 . A telescopic rod 11 of the hydraulic cylinder 13 is inserted into the refractory material conduit 7 . The end of the telescopic rod 11 is hinged to one end of the tungsten rod 9 through a buckle 10 .

[0016] The inner diameter of the end of the refractory conduit 7 away from the autoclave 1 gradually decreases along the direction from the autoclave 1 to the refractory conduit 7, and the inner diameter of the end face of the refractory conduit 7 away from the autoclave 1 is smaller than the diameter of the tungsten rod 9. When the tungsten rod moves to the end of the refractory conduit 7 away from the autoclave 1, the tungsten rod blocks the end to prevent the liquid metal from leaking out.

[0017] The refractory material conduit 7 is sheathed with a first steel pipe 6. The first steel pipe 6 is connected to the support structure of the autoclave 1. The first steel pipe 6 supports and protects the refractory material conduit 7. A dynamic seal 12 is provided at one end of the first steel pipe 6 away from the autoclave 1, and the dynamic seal 12 is provided on the telescopic rod 11 to seal the gas leaking from the gap.

[0018] The refractory material drainage pipe 8 is sleeved with a second steel pipe 14. The second steel pipe 14 is connected to the first steel pipe 6, and the second steel pipe 14 plays a role in supporting and protecting the refractory material drainage pipe 8.

[0019] A gate valve 2 is provided between the refractory drainage pipe 8 and the collecting tube 4, the outlet of the gate valve 2 is connected to the inlet of the collecting tube 4, the inlet of the gate valve 2 is connected to the refractory drainage pipe 8, and the gate valve 2 is connected to the second steel pipe 14 through the flange 5. The telescopic rod of the cylinder 3 of the gate valve 2 moves back and forth, so that the refractory drainage pipe 8 is connected or disconnected with the collecting tube 4. A graphite sealing ring is installed in the gate valve to block the gas leaking from the gap of this structure.

[0020] When the utility model is working, the metal liquid flows from the liquid metal outlet of the high-pressure reactor 1 through the refractory material conduit 7, the refractory material drainage pipe 8, the gate valve 2 and then enters the collecting cylinder 4. The problem that the liquid metal in the high-pressure reactor is difficult to be discharged smoothly after the reaction is completed is solved. The problem that the ordinary drainage pipeline is easy to be blocked and leaked will not occur. Safe and reliable full-automatic drainage is achieved.

[0021] The above embodiments are based on the technical solution of the present utility model, and provide detailed implementation methods and specific operation processes, but the protection scope of the present utility model is not limited to the above embodiments.
