DETAILED DESCRIPTION
[0018] The following will be combined with the embodiments to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.
[0019] It is to be noted that the concepts of directions “left”, “right”, “up”, “down”, “front”, “back”, “inside” and “outside” in the following schemes are all relative directions and will not be listed one by one here.
[0020] A heat-conducting structure of a lithium metal preparation reactor, reference Figure 1 The heat-conducting jacket unit 2 comprises multiple layers of heat-conducting jacket units 2 uniformly sleeved on the outer wall of the reactor 1. The multiple layers of heat-conducting jacket units 2 are not interconnected and together form a heat-conducting jacket. An oil guide pipe 3 is detachably provided on the heat-conducting jacket unit 2.
[0021] refer to Figure 2, a first annular heat conducting member 4 annularly sleeved on the outer wall of the reactor 1 is arranged in the heat conducting jacket unit 2. A second annular heat conducting member 5 matching the number and position of the first annular heat conducting member 4 is arranged in an annular manner on the inner wall of the reactor 1. The first annular heat conducting member 4 is connected to the second annular heat conducting member 5. When hot oil is filled into the heat conducting jacket unit 2, the hot oil transfers heat to the first annular heat conducting member 4, and the first annular heat conducting member 4 transfers heat to the second annular heat conducting member 5, which greatly improves the heat transfer efficiency.
[0022] refer to Figure 3 The heat-conducting jacket unit 2 is provided with an opening. Two closing plates 21 are rotatably arranged at the opening. A torsion spring 22 is arranged at the connection between the closing plate 21 and the opening. When the torsion spring 22 is in a natural state, the two closing plates 21 cooperate with each other to close the opening.
[0023] The outer wall of the oil guide pipe 3 is provided with a heat insulating sleeve 33. The heat insulating sleeve 33 is provided with four bayonet holes 31 evenly distributed in an annular manner. The heat insulating sleeve 33 is also provided with a sliding sleeve 32 for sealing the bayonet holes 31. The sliding sleeve 32 and the heat insulating sleeve 33 can be provided by screw rotation and sliding, or can be provided by sliding directly through a slide groove, depending on the actual situation.
[0024] The outer wall of the heat-conducting jacket unit 2 is provided with a positioning groove 23 that matches the position and number of the bayonet 31. A telescopic rod 24 is provided on the positioning groove 23. An inclined block 25 is provided at the end of the telescopic rod 24. A return spring 26 is sleeved on the telescopic rod 24. The inclined block 25 is inclined on the side close to the oil guide pipe 3.
[0025] When the metal lithium raw material needs to be subjected to a high-temperature reaction in the reactor 1, the oil pipe 3 is inserted into the corresponding heat-conducting jacket unit 2 according to the amount of the metal lithium raw material. When the heat pipe 3 is inserted into the heat-conducting jacket unit 2, the sleeve 32 does not close the bayonet 31. The oil pipe 3 is inserted into the heat-conducting jacket unit 2, the closing plate 21 rotates, the torsion spring 22 generates torque, the heat-insulating sleeve 33 squeezes the inclined block 25, and the reset spring 26 is compressed. When the heat pipe 3 enters a certain depth and the bayonet 31 is aligned with the inclined block 25, the reset spring 26 resets and sends the inclined block 25 into the bayonet 31, thereby fixing the oil pipe 3 and the heat-conducting jacket unit 2, and then the oil can be guided inside. When the oil is guided, the oil pipe 3 needs to be taken out, the sleeve 32 is slid, and the inclined block 25 is pushed away from the bayonet 31. The inclined block 25 no longer restricts the oil pipe 3, and the oil pipe 3 can be taken out at this time. During the process of taking out the oil pipe 3, the torsion spring 22 is restored, thereby driving the closing plate 21 to rotate and close the opening.
