Description

A drying mechanism for lithium aluminum hydride production

Technical Field

This utility model relates to the field of chemical product drying technology, and in particular to a drying mechanism for the production of lithium aluminum hydride.

Background Technology

Lithium aluminum hydride is an inorganic compound, mainly used as a carbonyl reagent and reducing agent. It is metastable at room temperature. During long-term storage, its properties change. In the chemical industry, lithium aluminum hydride is generally prepared by reacting lithium aluminum hydride with aluminum tribromide in an ether solution, followed by a drying process to obtain solid lithium aluminum hydride.

The existing process for drying lithium aluminum hydride basically involves transferring the lithium aluminum hydride into a drying chamber and drying it by heating air. Because the lithium aluminum hydride is piled up, the heat transfer to the interior of the lithium aluminum hydride is slow, resulting in uneven drying. At the same time, prolonged drying can easily cause changes in the properties of the lithium aluminum hydride on the surface, reducing the quality of the finished product.

Utility Model Content

To overcome the above shortcomings, this utility model provides a drying mechanism for lithium aluminum hydride production, which aims to improve the existing drying process, which fails to disperse the lithium aluminum hydride during drying, resulting in uneven drying and easy deterioration of the surface lithium aluminum hydride.

To achieve the above objectives, the present invention provides the following technical solution:

A drying mechanism for lithium aluminum hydride production includes a cabinet with a door on the front side. A feeding hopper is fixedly connected to the top of the cabinet. A drying chamber is opened inside the cabinet, with a feeding inlet between the feeding hopper and the drying chamber. A discharge outlet is opened at the bottom of the drying chamber, and a collection chamber is located at the bottom of the discharge outlet. A circulating hot air fan is installed on the right side of the cabinet, with a hot air pipe fixedly connected to the top of the circulating hot air fan and an air inlet pipe fixedly connected to the right side of the circulating hot air fan. A motor is fixedly connected to the left side of the cabinet, with a rotating shaft fixedly installed at the output end of the motor. Fixed columns are rotatably connected to both ends of the rotating shaft, and a stirring column is fixedly connected to the middle of the rotating shaft. A dehumidification mechanism is installed on the left side of the drying chamber for dehumidifying the drying chamber.

Preferably, the dehumidification mechanism includes an air outlet pipe, the top end of which is rotatably connected to the left side of the drying chamber, the bottom end of which is rotatably connected to a hot air exchanger, the top of which is fixedly connected to an air inlet pipe, a filter column fixedly connected to the top end of the air inlet pipe and the top end of the air outlet pipe, and a breathable plate fixedly connected to the top end of the filter column.

Preferably, the bottom surface of the filter column is in contact with the left side surface of the collection chamber.

Preferably, the rotating shaft passes through and extends to the inner wall of the right side of the cabinet, and the fixing column is fixedly connected to the cabinet.

Preferably, the bottom surface of the motor is in contact with the top surface of the hot air exchanger.

Preferably, one end of the hot air duct extends through and to the inner wall of the right side of the drying chamber.

Preferably, the surface of the stirring column is in contact with the inner wall of the drying chamber.

Preferably, a material trough plug is provided at the top of the feed hopper, and the surface of the material trough plug is in contact with the inner wall of the top of the feed hopper.

This utility model has the following beneficial effects:

1. In this utility model, by starting the circulating hot air blower, lithium aluminum hydride enters the drying chamber through the feed hopper. The circulating hot air blower delivers heated air into the drying chamber through the hot air pipe. At the same time, the motor starts, and the rotating shaft drives the stirring column to rotate. The fan blades on the stirring column continuously tumble and disperse the lithium aluminum hydride in the drying chamber, so that the lithium aluminum hydride is heated evenly. After the lithium aluminum hydride is dried, it falls naturally into the collection chamber through the discharge port. Thus, the lithium aluminum hydride is continuously tumbled and dispersed during the drying process, so as to achieve uniform drying, accelerate the drying speed of lithium aluminum hydride, and avoid the quality change that may occur when lithium aluminum hydride is piled up for a long time during drying, which would affect the quality of the finished product.

2. In this utility model, the hot air exchanger is activated, and air from the collection chamber is drawn in through the air inlet pipe. Dry air is then sent into the collection chamber through the air outlet pipe. The filter columns and permeable plates set at the front end of the air inlet and air outlet pipes prevent lithium aluminum hydride from entering the pipeline and causing a reduction in output. This achieves the goal of keeping the air in the drying chamber dry and avoiding the condensation of water vapor on the inner wall of the feed inlet, which would affect the lithium aluminum hydride raw material.

Lithium aluminum hydride in the feed hopper 2 enters the drying chamber 4 through the feed inlet 12. The circulating hot air fan 9 delivers heated air into the drying chamber 4 through the hot air pipe 7. At the same time, the motor 10 starts, and the rotating shaft 6 drives the stirring column 5 to rotate. The fan blades on the stirring column 5 continuously tumble and disperse the lithium aluminum hydride in the drying chamber 4, so that the lithium aluminum hydride is heated evenly. After the lithium aluminum hydride is dried, it falls naturally into the collection chamber 3 through the discharge port 11. The finished lithium aluminum hydride is taken out by opening the cabinet door 8. Thus, the lithium aluminum hydride is continuously tumbled and dispersed during the drying process, so as to achieve uniform drying, accelerate the drying speed of lithium aluminum hydride, and avoid the quality change of lithium aluminum hydride that will affect the quality of the finished product when it is piled up for a long time during drying.

Referring to Figure 4, the dehumidification mechanism includes an air outlet pipe 17. The top end of the air outlet pipe 17 is rotatably connected to the left side of the drying chamber 4. The bottom end of the air outlet pipe 17 is rotatably connected to a hot air exchanger 15. The top of the hot air exchanger 15 is fixedly connected to an air inlet pipe 16. The top end of the air inlet pipe 16 and the top end of the air outlet pipe 17 are fixedly connected to a filter column 18. The top end of the filter column 18 is fixedly connected to a breathable plate 20.

When the hot air exchanger 15 is activated, it draws in air from the collection chamber 3 through the air inlet pipe 16 and sends dry air into the collection chamber 3 through the air outlet pipe 17. The filter column 18 and the air permeable plate 20 set at the front end of the air inlet pipe 16 and the air outlet pipe 17 prevent lithium aluminum hydride from entering the pipeline, thus avoiding affecting the production of lithium aluminum hydride. This keeps the air in the drying chamber 3 dry and prevents the condensation of water vapor on the inner wall of the feed inlet 12, which would affect the lithium aluminum hydride raw material.

Referring to Figure 2, the bottom surface of the filter column 18 is in contact with the left side surface of the collection chamber 3, and the filter column 18 and the air vent plate 20 work together to prevent lithium aluminum hydride from entering the pipeline.

Referring to Figure 2, the rotating shaft 6 passes through and extends to the inner wall of the right side of the cabinet 1, and the fixed column 13 is fixedly connected to the cabinet 1, thereby ensuring that the rotating shaft 6 rotates smoothly inside the drying chamber 4.

Referring to Figure 2, the bottom surface of the motor 10 is in contact with the top surface of the hot air exchanger 15 to keep the motor 10 stable.

Referring to the figure, one end of the hot air pipe 7 passes through and extends to the inner wall of the right side of the drying chamber 4. The air is heated by the circulating hot air fan and enters the drying chamber 4 to achieve the drying of lithium aluminum hydride.

Referring to the figure, the surface of the stirring column 5 is in contact with the inner wall of the drying chamber 4, so that the lithium aluminum hydride can be continuously turned over when the stirring column 5 rotates to prevent the lithium aluminum hydride from accumulating.

Referring to the figure, a material trough plug 14 is provided at the top of the feed hopper 2. The surface of the material trough plug 14 is in contact with the inner wall of the top of the feed hopper 2 so as to seal the feed hopper 2 after lithium aluminum hydride is added, thereby achieving a seal for the entire drying mechanism.

Working principle: The circulating hot air blower 9 is started, and the lithium aluminum hydride in the feed hopper 2 enters the drying chamber 4 through the feed inlet 12. The circulating hot air blower 9 delivers heated air into the drying chamber 4 through the hot air pipe 7. Simultaneously, the motor 10 starts, and the rotating shaft 6 drives the stirring column 5 to rotate. The blades on the stirring column 5 continuously tumble and disperse the lithium aluminum hydride in the drying chamber 4, ensuring uniform heating. After drying, the lithium aluminum hydride naturally falls into the collection chamber 3 through the discharge port 11. The finished lithium aluminum hydride is then removed by opening the cabinet door 8. This process continuously tumbles and disperses the lithium aluminum hydride during drying, ensuring uniform drying. The drying process accelerates the drying speed of lithium aluminum hydride, preventing quality changes that may occur when lithium aluminum hydride is piled up for a long time during drying, thus affecting the quality of the finished product. The hot air exchanger 15 is activated, drawing in air from the collection chamber 3 through the air inlet pipe 16 and sending dry air into the collection chamber 3 through the air outlet pipe 17. The filter column 18 and the air permeable plate 20 set at the front end of the air inlet pipe 16 and the air outlet pipe 17 prevent lithium aluminum hydride from entering the pipeline, thus avoiding affecting the production of lithium aluminum hydride. This ensures that the air in the drying chamber 3 is kept dry, preventing the condensation of water vapor on the inner wall of the feed inlet 12, which would affect the lithium aluminum hydride raw material.
