Description

Technical Field

[0001] This utility model relates to the field of lithium tetrachloroaluminate production technology, and in particular to lithium tetrachloroaluminate synthesis furnace. Background Technology

[0002] Currently, in the battery field, lithium thionyl chloride batteries are the chemical batteries known to date with the highest energy and the highest specific energy, and are considered the "ultimate" high-energy chemical power source. They possess advantages such as high voltage, stable operating voltage, wide applicable temperature range, good low-temperature performance, and long shelf life. The applications of this battery are becoming increasingly widespread, with lithium aluminum tetrachlorosilane being an indispensable electrolyte.

[0003] Because lithium aluminum tetrachloro is extremely hygroscopic and highly corrosive in air, its main reaction must be carried out under a dry argon atmosphere, where anhydrous aluminum trichloride and anhydrous lithium chloride are mixed in an equimolar ratio and melted at a certain temperature.

[0006] Therefore, this utility model proposes a lithium tetrachloroaluminate synthesis furnace.

[0007] Preferably, the present invention may also have the following technical features:

[0008] The lithium aluminum tetrachlorometallurgical synthesis furnace includes a furnace cavity and an outer shell. The furnace cavity is located inside the outer shell. The furnace cavity contains at least an electric heater, a first vertical wall, a bottom plate, and a second vertical wall. The first and second vertical walls are respectively connected to the two ends of the bottom plate, forming a U-shaped structure. The electric heater is used to heat the furnace cavity. The furnace cavity also contains at least one layer of perforated partition. The two ends of the perforated partition are fixed to the first and second vertical walls, forming a holding area. The front side of the outer shell has a furnace door to facilitate the placement and removal of material bottles onto the perforated partition.

[0009] Furthermore, each layer of mesh partition is supported by a brick wall in the middle.

[0010] Furthermore, it also includes a second electric heater and a third electric heater, wherein a mezzanine space is provided inside the first and second vertical walls and the second and third electric heaters are respectively installed therein, and the mezzanine space is connected to the storage area.

[0011] Furthermore, an insulating brick layer is provided between the interlayer space and the nearest outer shell wall.

[0012] Furthermore, the mezzanine space is provided with connecting openings on the front, back, and top sides.

[0013] Furthermore, it also includes an air vent, which is located on the top surface of the outer shell and connects to the interior of the furnace cavity.

[0014] Furthermore, it also includes an air outlet pipe, the upper end of which is fixed to the air outlet hole, and the lower end abutting against the mesh partition arranged on the uppermost layer.

[0015] The advantages of this invention compared to existing technologies include: the three electric heaters are arranged in a U-shape, transferring heat simultaneously from the bottom and both sides of the container area, resulting in high heat transfer efficiency and more uniform heating within the container area. When multiple layers of perforated partitions are provided, the partitions are spaced apart, increasing the number of material bottles that can be placed.

[0019] The present invention will now be described in further detail with reference to specific embodiments and the accompanying drawings. It should be emphasized that the following description is merely exemplary and is not intended to limit the scope and application of the present invention.

[0020] Non-limiting and non-exclusive embodiments will be described with reference to the following figures, wherein the same reference numerals denote the same parts unless otherwise specifically stated.

[0021] like Figure 1-3The lithium tetrachloroaluminate synthesis furnace shown includes a furnace cavity 13 and an outer shell 1. The furnace cavity 13 is located inside the outer shell 1. The furnace cavity 13 contains at least an electric heater, a first vertical wall 2, a bottom plate 6, and a second vertical wall 4. The first vertical wall 2 and the second vertical wall 4 are respectively connected to the two ends of the bottom plate 6, forming a U-shaped structure. The furnace cavity 13 also contains at least one layer of perforated partitions 3. The two ends of the perforated partitions 3 are fixed to the first vertical wall 2 and the second vertical wall 4, forming a holding area. In this way, when multiple layers of perforated partitions 3 are provided, the perforated partitions 3 are spaced apart, increasing the number of material bottles that can be placed. The material bottles contain lithium chloride and aluminum trichloride in a weight ratio, improving the efficiency of lithium tetrachloroaluminate synthesis. Preferably, each layer of perforated partitions 3 is further supported by a brick wall 21 in the middle to prevent deformation due to the long span of the perforated partitions 3 and to improve the load-bearing capacity of the perforated partitions 3. The front side of the outer shell 1 is provided with a furnace door 7 to facilitate the placement and removal of material bottles onto the perforated partitions 3.

[0022] The electric heater, used for heating, is installed between the perforated partition 3 and the base plate 6. When the electric heater is activated, heat is transferred upwards layer by layer through the mesh of the perforated partition 3. Preferably, to improve heating efficiency, two additional sets of electric heaters are provided. Specifically, a sandwich space 41 is provided inside the first vertical wall 2 and the second vertical wall 4, and a second and third electric heater are installed therein. The sandwich space 41 is connected to the storage area, allowing the heat from the second and third electric heaters to be transferred to the storage area, thereby improving the heating of the material bottles placed on the perforated partition 3. Preferably, an insulating brick layer 42 is provided between the sandwich space 41 and the nearest outer shell wall to prevent the second and third electric heaters in the sandwich space 41 from heating the outer shell 1 to a high temperature. In other words, the two sandwich spaces 41 sandwich the storage area in the middle, and during heat transfer, the heat transfer to the nearby outer shell wall is significantly reduced, with most of the heat being conducted to the storage area.

[0023] Preferably, the interlayer space 41 has connecting openings 11 on both the front and rear sides, and the upper side of the interlayer space 41 is open to facilitate heat transfer to the holding area. In this way, the connecting openings 11 connect the interlayer space 41 and the holding area, enabling heat transfer. The three electric heaters are arranged in a U-shape, transferring heat to the holding area simultaneously from the bottom and left and right sides, resulting in high heat transfer efficiency and more uniform heating within the holding area.

[0024] It also includes a vent 8, which is located on the top surface 12 of the outer shell and connects to the interior of the furnace cavity 13. When lithium chloride and aluminum trichloride are heated in the furnace cavity 13 to synthesize lithium tetrachloroaluminate, the vent 8 is blocked with insulating cotton to prevent heat loss from the furnace cavity; after the synthesis reaction is completed, the insulating cotton is removed to allow the furnace cavity to connect with the atmospheric environment. Preferably, it also includes a vent pipe 5, the upper end of which is fixed to the vent 8, and the lower end abuts against the mesh partition 3 arranged on the uppermost layer.

[0025] Those skilled in the art will recognize that numerous variations are possible with respect to the above description, and the embodiments and figures are merely for describing one or more specific implementations.

[0026] Although exemplary embodiments of the present invention have been described and illustrated, those skilled in the art will understand that various changes and substitutions can be made thereto without departing from the spirit of the present invention. Furthermore, many modifications can be made to adapt specific situations to the doctrine of the present invention without departing from the central concept of the present invention described herein. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but may include all embodiments and equivalents that fall within the scope of the present invention.
