As mentioned above, the structure of the crushing and feeding machine 511 is the same as that of the crushing and feeding device provided in the utility model with the application number CN201820865173.3 (see fig. 7), and then, the crushing and feeding machine 511 also includes a guiding groove, which is inserted into the material input port 5102. The furnace cover 5101 is arranged at the furnace opening of the molten salt furnace 510, so that the heating efficiency of the molten salt furnace 510 on the materials can be improved, and the heat in the molten salt furnace 510 is effectively prevented from being dissipated. In addition, a material input interface 5102 is arranged on the furnace cover 5101, and the crushing feeder 511 is connected with the material input interface 5102; this ensures that the broken nitrate solid can smoothly enter the molten salt furnace 510 without opening the furnace cover 5101, and prevents the molten nitrate in the molten salt furnace 510 from splashing out when the broken solid nitrate falls into the molten salt furnace 510.
Further, the fire hole of the molten salt furnace 510 is divided into a first open area and a second open area; the furnace lid 5101 includes a first lid 5101a and a second lid 5101 b; the first cover 5101a is fixedly connected to the molten salt furnace 510 for shielding the first open area; the second cover 5101b is movably connected to the molten salt furnace 510, and is used for shielding or opening the second open area; the material input port 5102 is disposed on the first cover 5101 a.

Since the second cover 5101b is opened when the inside of the molten salt furnace 510 needs to be cleaned, the crushing feeder 511 is not required to be detached from the material input port 5102 before the second cover 5101b is opened because the crushing feeder 511 is connected to the material input port 5102 of the first cover 5101 a.
Further, a pair of rails 5103 are disposed at the second open region of the furnace opening of the molten salt furnace 510, the rails 5103 extend out of the furnace opening of the molten salt furnace 510, and the second cover 5101b is slidably disposed on the pair of rails 5103. Specifically, a pair of the rails 5103 are fixed to front and rear edges of the second open area, respectively, the rails 5103 extend out of the furnace opening of the molten salt furnace 510 in the left-right direction, and the ends of the rails 5103 extending to the outside of the furnace opening of the molten salt furnace 510 are supported by pillars. A plurality of rollers may be disposed on the front and rear sides of the second cover 5101b, respectively, so that an operator can push the second cover 5101b to move on the pair of rails 5103.

Specifically, the pumping mechanism 512 is a high-temperature submerged pump. By adopting the design, the inside of the molten salt furnace 510 is convenient to clean. Since, when we need to clean the inside of the molten salt furnace 510, only the second cover 5101b needs to be opened, since the pump body 5121 is fixed to the first cover 5101a and the pipette 5122 protrudes into the molten salt furnace 510 through the first cover 5101a, the pump body 5121 is fixed to the first cover 5101a, and the pipette 5122 protrudes into the molten salt furnace 510 through the first cover 5101a, it is not necessary to detach the pump body 5121 and the pipette 5122 from the first cover 5101a before opening the second cover 5101 b.

In addition, only the joint of the metal hose 5124 and the drain pipe 5123 needs to be protected for the second time, so that the nitrate solution can be effectively prevented from leaking and splashing. In order to prevent the nitrate solution from being solidified in the metal hose 5124 due to heat dissipation and causing blockage, an insulating layer may be further disposed on the outer side of the metal hose 5124.
Further, a collar for inserting the metal hose 5124 is fixed to an inner wall of the toughening furnace 400. Specifically, the lantern ring is fixed on the inner wall of the toughening furnace 400 by welding, and the inner diameter of the lantern ring is just matched with the outer diameter of the metal hose 5124, so that the metal hose 5124 can be stably inserted into the lantern ring. Therefore, before the addition of the nitrate melt to the toughening furnace 400, the metal hose 5124 may be inserted into the collar in advance to fix the metal hose 5124, thereby preventing the metal hose 5124 from being thrown out of the toughening furnace 400 when the nitrate melt is added.
