Description

Technical Field

[0001] The utility model relates to the field of calcination equipment, in particular to an aluminum-based crucible for calcining anode materials. Background Art

[0002] The negative electrode refers to the end with a lower potential in a power source. In a primary battery, it refers to the electrode that undergoes oxidation, and the negative electrode is the pole where electrons flow out in an electric circuit. The anode material refers to the raw material that constitutes the negative electrode in a battery. Common anode materials include carbon anode materials, tin-based anode materials, lithium-containing transition metal nitride anode materials, alloy anode materials, and nanoscale anode materials. When calcining anode materials, the commonly used equipment is an aluminum-based crucible. The anode material is loaded into the aluminum-based crucible and then placed in a calcining furnace for calcination. The existing aluminum-based crucibles are not convenient to move and need to be taken out of the high-temperature calcining furnace using clamping equipment, which is inconvenient for taking. Therefore, it is particularly necessary to develop an aluminum-based crucible for calcining anode materials that is convenient to move. Summary of the Invention

[0003] The purpose of the utility model is to provide an aluminum-based crucible for calcining anode materials, which has the advantage of being convenient to move.

A plurality of limiting holes are provided at the upper end of the crucible, and a plurality of limiting columns corresponding to the limiting holes are provided at the lower end of the crucible. Moving seats are provided on both sides of the crucible. A cavity is provided inside the moving seat, a through hole is provided in the cavity, notches are provided on both sides of the through hole, and a T-shaped plate is detachably arranged in the cavity.

[0006] Preferably, a plurality of fins are vertically arranged on the outer side surface of the crucible.

[0007] Preferably, a plurality of ventilation holes are formed on the side surfaces of the fins.

[0008] Preferably, a chamfer is provided on the upper end surface of the limiting hole.

[0009] Preferably, a rounded corner is provided on the lower end surface of the limiting column.

[0010] Preferably, a plurality of through grooves are formed on the upper end surface of the crucible.

[0011] Compared with the prior art, the beneficial effects are as follows:

[0012] In the present utility model, two crucibles are stacked up and down, and the limiting posts of the upper crucible are inserted into the limiting holes of the lower crucible to realize the connection of the two crucibles. When it is necessary to move a row of crucibles, the T-shaped plate is inserted into the through hole, and the T-shaped plate is inserted into the cavity by using the notch. The T-shaped plate is rotated to block the T-shaped plate by the cavity, so as to facilitate pulling the crucible by using the T-shaped plate, thereby facilitating the movement of the crucible.
