[0002] In the production of superhard materials, namely diamonds, non-metallic impurities such as pyrophyllite and dolomite need to be removed. The current method is to remove these impurities by boiling in alkali. The tool for boiling in alkali is a boiling furnace. The diamonds are placed in the boiling furnace along with alkali. The alkali in the boiling furnace is heated to generate high temperature to remove non-metallic impurities such as pyrophyllite and dolomite.

However, in the current caustic soda furnace structure, after caustic soda boiling is completed, the alkali and materials in the furnace need to be poured out manually. The corrosive alkali can easily splash onto human skin, thus affecting the health of operators. At the same time, the existing caustic soda furnace structure is usually heated by an electric heating wire built into the furnace. When the heating component fails, it is not easy to disassemble and repair, which seriously affects the use effect of the caustic soda furnace. It is necessary to improve it.

An insulation layer 102 is provided on the inner wall of the outer shell 1 to improve the heat preservation effect of the inner liner container 2. The insulation layer 102 is a longitudinally arranged circular tube and is fixedly fitted onto the inner circumferential side wall of the outer shell 1. The inner liner container 2 is open at the top. The inner container 2 is cylindrical and its axis coincides with the axis of the outer shell 1. The inner container 2 is fitted inside the insulation layer 102. The top of the inner container 2 extends to the outside of the top of the outer shell 1. A liquid outlet 201 is provided on one side of the top of the inner container 2 to facilitate the pouring of materials. A fixing flange 202 is welded to the outer periphery of the top of the inner container 2 and is detachably connected to the top of the reinforcing beam 101 through the fixing flange 202. A handle 203 is symmetrically provided on both sides of the top of the inner container 2 to facilitate the disassembly and lifting of the inner container 2. The handle 203 is welded to the outer wall of the top of the inner container 2 and is located above the fixing flange 202.

[0021] The fixed flange 202 is arranged in a circular shape and is located above the top of the outer shell 1. The fixed flange 202 is sleeved on the outer peripheral side wall of the top of the inner liner container 2 and is welded to the outer side wall of the inner liner container 2. The fixed flange 202 is provided with four first bolt holes, which are corresponding to the second bolt holes provided at the top of the four reinforcing beams 101. The first bolt holes and the second bolt holes are connected by fixed bolts 4.

[0022] When the inner liner is placed inside the outer shell, the fixing flange is positioned just above the top of the outer shell. Then, the first bolt hole at the edge of the fixing flange is connected to the second bolt hole at the top of the reinforcing beam using fixing bolts. It adopts an assembly structure, which facilitates disassembly and maintenance operations.

[0023] The power rotation mechanism includes a first support frame 6, a second support frame 7, a first rotating shaft 8, a second rotating shaft 9, and a power motor 10. The first support frame 6 and the second support frame 7 are both stably fixed to the ground and are symmetrically arranged on both sides of the reaction vessel. A first bearing seat 601 is fixedly connected to the top of the first support frame 6, and a second bearing seat 701 is fixedly connected to the top of the second support frame 7.

The power motor 10 is fixedly connected to the second support frame 7 through the motor fixing plate 702.

[0024] During the diamond caustic soda boiling process, diamonds are placed in an inner container, and then caustic soda solution is poured in. The material in the inner container is heated by a heating layer, and the heating is controlled by a temperature control device to remove impurities from the diamonds. After the caustic soda boiling process is completed, a remotely controlled motor starts working. The motor drives the reaction vessel to rotate via a first rotating shaft. As the reaction vessel rotates, the material in the inner container flows out from the outlet, allowing for material removal and preventing the spilled caustic soda solution from causing harm to personnel. After the material in the inner container is poured out, the motor is reversed to restore the reaction vessel to its original state, allowing for the next diamond caustic soda boiling operation.

[0025] A heating layer for heating the inner liner container 2 is provided between the outer wall of the inner liner container 2 and the inner wall of the insulation layer 102.

[0026] The heating layer includes two symmetrically arranged heating plates 3 on both sides of the inner container 2. Both heating plates 3 are arc-shaped and their openings face each other. The edges of both heating plates 3 are provided with corresponding connecting ears 302. The corresponding connecting ears 302 on the two heating plates 3 are fixedly connected by fastening bolts 5. After the two heating plates 3 are fixedly connected by fastening bolts 5, they form a longitudinal circular tube structure and are fixedly sleeved on the outer periphery of the inner container 2. The bottom ends of the two heating plates 3 are provided with power lines 301. The power lines 301 extend from the clearance through hole 103 at the bottom end of the outer shell 1 and are connected to the equipment control cabinet.

[0027] A temperature measuring head for monitoring the temperature of the material inside the inner container 2 is installed on the side wall of the inner container 2, and the temperature measuring head is connected to the circuit of the equipment control cabinet.

[0028] The design, which combines two heating plates to form the heating layer, creates a detachable structure between the heating layer and the inner container. This facilitates disassembly and replacement of the heating plates in case of malfunction, improving the maintenance convenience of the heating layer. Simultaneously, the temperature of the material inside the inner container can be monitored using a temperature sensor, and the heating status of the heating plates can be controlled based on the monitoring results, ultimately achieving constant temperature heating operation in the caustic soda furnace. Its simple structure and convenient operation further enhance the effectiveness of this invention.

[0029] This invention employs a power-driven rotating mechanism on the outside of the reaction tank. After caustic soda boiling is completed, the tank can be tilted and poured out, allowing the alkali solution and other materials to be discharged. This can be achieved remotely by the operator controlling the motor in the rotating mechanism, preventing alkali solution from splashing onto the operator's skin and affecting their health, thus ensuring the safety of the caustic soda boiling furnace operation. Furthermore, the reaction tank features a detachable outer shell and inner container. In case of heating component failure, the outer shell and inner container can be disassembled, and the heating layer on the outside of the inner container can be repaired or replaced. This simple and quick design improves the maintenance convenience of the heating components in the caustic soda boiling furnace and facilitates subsequent maintenance by the operator, further enhancing the furnace's performance.

[0030] On the other hand, this utility model also has two temperature measuring heads installed on the side wall and bottom of the reaction vessel, and uses a high-precision temperature measuring instrument for temperature monitoring, which ensures that the temperature of the caustic soda furnace remains constant, the caustic soda reaction is more complete, and avoids the situation where the material is burned due to excessive temperature, thus further improving the effectiveness of this utility model.
