Description

Technical Field

[0001] This utility model relates to the technical field of melting pot devices, specifically a high-efficiency melting pot device for nitrous oxide production. Background Technology

[0002] A high-efficiency melting pot device for nitrous oxide production refers to a specialized piece of equipment used in the nitrous oxide production process to efficiently melt solid raw materials into a liquid state for subsequent chemical reactions or purification processes. Its core function is to improve melting efficiency and uniformity through structural designs such as stirring and sealing.

[0003] In existing nitrous oxide production, most melting pot devices use electric heating plates or local heating wires directly installed at the bottom of the pot to accelerate the melting of solid raw materials. However, heat is only transferred from the bottom of the pot or a local area, resulting in uneven heating of the raw materials inside the pot. The lack of an effective heat exchange structure means that heat cannot be evenly diffused inside the pot. Even if the heating time is extended, it is difficult to achieve uniform melting of the raw materials. Therefore, we propose a high-efficiency melting pot device for nitrous oxide production.

[0013] The beneficial effects of this utility model are:

[0014] 1. This utility model, through the arrangement of a heating furnace and a spiral heat-conducting pipe, introduces heat-conducting oil into the heating furnace through its inlet. The furnace heats the oil, and a delivery pump draws and pressurizes the oil, which is then transported through a connecting pipe and a second L-shaped pipe to the spiral heat-conducting pipe. The spiral heat-conducting pipe surrounds the outside of the melting pot body, conducting heat to the melting pot body through large-area contact, uniformly heating the nitrous oxide raw material inside. The low-temperature heat-conducting oil, after releasing heat, returns to the heating furnace through the spiral heat-conducting pipe loop. After being heated again, it is drawn back by the delivery pump, and this cycle repeats continuously, providing a stable heat source for the solid raw material, ensuring uniform heating, efficient melting, and improving work efficiency.

This utility model, through the setting of a rotating motor and a sawtooth-shaped stirring component, enables the connecting plate to be pressed down by activating the electric push rod, which in turn causes the fixing plate and sealing ring to seal the top of the shell and the melting pot body respectively. By activating the rotating motor, the output end of the rotating motor drives the sawtooth-shaped stirring component to stir, which can accelerate the melting of solid raw materials. When the sawtooth-shaped stirring component comes into contact with the solid raw materials, the sharp teeth on its surface can break the fixed raw materials, further accelerating the melting of solid raw materials.

[0024] In practice, heat transfer oil is added from the inlet of the heating furnace 53 and heated by the heating furnace 53. The transfer pump 56 is started, which draws out and pressurizes the heat transfer oil in the heating furnace 53. The heat transfer oil is then transported to the spiral heat transfer pipe 2 through the connecting pipe 54 and the second L-shaped pipe 57. The spiral heat transfer pipe 2 surrounds the outside of the melting pot body 1 and conducts heat to the melting pot body 1 through large-area contact, uniformly heating the nitrous oxide raw material in the melting pot body 1. The low-temperature heat transfer oil that has released heat returns to the heating furnace 53 through the loop of the spiral heat transfer pipe 2. After being heated, it is drawn out again by the transfer pump 56. This cycle repeats continuously, providing a stable heat source for the solid raw material, ensuring uniform heating and efficient melting.

[0025] As a technical optimization of this utility model, the outer wall of the casing 3 is fixedly connected with three support legs 9 for supporting the device, the bottom ends of the three support legs 9 are fixedly connected with a base plate 10, the bottom of the melting pot body 1 is fixedly connected with a conical guide pipe 6, the outer side of the conical guide pipe 6 is fixedly sleeved on the inner wall plate at the bottom end of the casing 3, the bottom end of the conical guide pipe 6 is fixedly connected with a discharge pipe 7, and the bottom of the discharge pipe 7 is fixedly installed with a control valve 8 for sealing the discharge pipe 7.

[0026] In practice, the device is supported by the support leg 9 and the base plate 10. By connecting an external pipe to the bottom of the discharge pipe 7 and eliminating the seal of the control valve 8 on the discharge pipe 7, the fused liquid can be discharged, facilitating subsequent processing.

[0027] As a technical optimization of this utility model, the stirring mechanism 4 includes an electric push rod 41 fixedly installed on the top surface of the base plate 10. A connecting plate 42 is fixedly connected to the telescopic end of the electric push rod 41. A fixing plate 43 is fixedly connected to the lower surface of the connecting plate 42. A sealing ring 44 is fixedly connected to the lower surface of the fixing plate 43. A circular plate 45 is fixedly sleeved in the inner cavity of the sealing ring 44. The top surface of the circular plate 45 is fixedly connected to the bottom surface of the fixing plate 43. A rotary motor 46 is fixedly installed on the bottom surface of the circular plate 45. The output end of the rotary motor 46 is fixedly connected to... There is a serrated stirring component 47. A scraper 49 is fixedly connected to one side wall plate of the serrated stirring component 47. The side wall plate of the scraper 49 away from the serrated stirring component 47 is movably fitted with the inner cavity wall plate of the melting pot body 1. A sealing plate 48 is rotatably connected to the bottom of the serrated stirring component 47. The outer circumference of the sealing plate 48 is movably fitted with and sealed to the bottom wall plate of the inner cavity of the melting pot body 1. The outer circumference of the fixing plate 43 is movably fitted with the bottom wall plate of the inner cavity of the sleeve 3. The outer circumference of the sealing ring 44 is movably fitted with the top wall plate of the inner cavity of the melting pot body 1.

[0028] In practice, by activating the electric push rod 41, the extension end of the electric push rod 41 drives the connecting plate 42 to press down, which can drive the fixing plate 43 and the sealing ring 44 to seal the top of the shell 3 and the melting pot body 1 respectively. By activating the rotating motor 46, the output end of the rotating motor 46 drives the sawtooth stirring piece 47 to stir, which can accelerate the melting of solid raw materials. When the sawtooth stirring piece 47 stirs and comes into contact with the solid raw materials, the tooth tips on the surface can break the fixed raw materials, further accelerating the melting of solid raw materials.

[0029] In use, this invention involves activating the electric push rod 41, which in turn raises the connecting plate 42, placing the raw material inside the melting pot body 1. Heat transfer oil is then added through the inlet of the heating furnace 53, which heats the oil. The electric push rod 41 then lowers the connecting plate 42, causing the fixing plate 43 and sealing ring 44 to seal the top of the casing 3 and the melting pot body 1, respectively. The rotating motor 46 is activated, driving the sawtooth-shaped stirring element 47 to stir the mixture. Finally, the delivery pump 56 pumps the contents of the heating furnace 53 into the furnace. The heat transfer oil is extracted and pressurized, and then transported to the spiral heat transfer pipe 2 through the connecting pipe 54 and the second L-shaped pipe 57. The spiral heat transfer pipe 2 surrounds the outside of the melting pot body 1, and conducts heat to the melting pot body 1 through large-area contact, uniformly heating the nitrous oxide raw material in the melting pot body 1. After releasing heat, the low-temperature heat transfer oil returns to the heating furnace 53 through the loop of the spiral heat transfer pipe 2. After being heated, it is drawn out again by the delivery pump 56. This cycle repeats continuously, providing a stable heat source for the solid raw material, ensuring uniform heating and efficient melting. After melting is completed, the control valve 8 is released from the discharge pipe 7, and the fused liquid is discharged.
