Description

Technical Field

[0001] The utility model relates to the technical field of single crystal furnaces, in particular to a holding device for a single crystal furnace heater and battery sheet processing equipment. Background Art

[0002] In the related art, after the single crystal furnace is dismantled, the thermal field components are taken out, and the high-temperature thermal field components are moved to the designated grinding and cleaning room for cleaning to dissipate heat and cool down; after cleaning, the thermal field components need to be installed in sequence, and during the installation process, the thermal field components are continuously exposed to the air and in contact with the air to dissipate heat and cool down. High-temperature thermal field components are prone to thermal expansion and contraction when exposed to low-temperature air.

[0030] Reference below Figure 1-Figure 8 The following describes a device 100 for holding a single crystal furnace heater 200 according to an embodiment of the first aspect of the present utility model.

[0031] like Figure 1-Figure 8 As shown, the holding device 100 of the single crystal furnace heater 200 according to the first embodiment of the utility model includes a heat preservation box body 1, a box door 2 and a placement component 3.

[0032] Specifically, the heat preservation box 1 has a receiving chamber 11, and a suction port 12 connected to the receiving chamber 11 is formed on the top of the heat preservation box 1. The receiving chamber 11 is evacuated through the suction port 12. The heat preservation box 1 is in a first direction (for example, Figure 1 The door 2 is pivotally arranged on the open side of the heat preservation box 1. The placement component 3 is arranged in the accommodating cavity 11, and the placement component 3 is suitable for placing the single crystal furnace heater 200.

[0033] For example, in Figure 1 , Figure 4 and Figure 5 In the example, the accommodating cavity 11 of the heat preservation box 1 is suitable for installing the single crystal furnace heater 200, and the door 2 is pivotally arranged on the open side of the heat preservation box 1, that is, the door 2 can be switched between an open position and a closed position. When the door 2 is opened, the user can take out the single crystal furnace heater 200 in the accommodating cavity 11 through the open side or put the single crystal furnace heater 200 into the accommodating cavity 11.
