[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0020] Please refer to Figure 1 , Figure 1 It is a schematic structural diagram of an automatic crucible cleaning device provided by a specific embodiment of the present invention.

[0021] An automatic crucible cleaning device provided by an embodiment of the present invention includes: a tunnel furnace 2, a conveying device 3, a first rotary dust removal device 4, a first purging nozzle, and a storage device 5. Specifically, the first rotary dust removal device 4 includes a drum and a driving motor. A baffle 8 is provided inside the drum. The crucible can be lifted to a certain height along with the circular motion to change the orientation of the crucible opening, so that the dust drops. In addition, when the drum is at a certain inclination angle, the crucible can fall downward to facilitate falling into the storage device 5. In addition, through holes are provided on the side wall of the drum to facilitate the first purging nozzle to clean the dust in the crucible. Specifically, one or more nozzles can be arranged around the drum. During specific operation, the sample can be directly loaded manually or by a robot. After the crucible is placed on the conveying device 3, the conveying device 3 conveys the crucible into the tunnel furnace 2 for burning. After burning, the conveying device 3 conveys the crucible into the first rotary dust removal device 4 again. The crucible makes a circular motion in the first rotary dust removal device 4, and at the same time, the dust in the first rotary dust removal device 4 is removed through the first purging nozzle. As the first rotary dust removal device 4 rotates, the crucible will automatically fall into the storage device 5. During the process of crucible dust removal, no manual intervention is required, continuous sample loading can be carried out, and the cleaning efficiency is relatively high.

[0022] Further, it further includes a second rotary dust removal device 6 located at the feeding port of the conveying device 3. A second purging nozzle is provided on the outer periphery of the second rotary dust removal device 6. The second rotary dust removal device 6 is the same as the first rotary dust removal device 4, and both realize the flipping of the crucible through circular motion and realize the cleaning of dust through the purging nozzle 7. It can be understood that before the crucible is burned, it can be preliminarily cleaned by the second rotary dust removal device 6. After cleaning, the crucible will automatically fall onto the conveying device 3 as the second rotary dust removal device 6 rotates, and then is conveyed into the tunnel furnace 2 by the conveying device 3 for subsequent dust removal operations.

[0023] Furthermore, a door control device is provided at the entrance of the tunnel furnace 2, and a detection switch is provided on the conveying device 3. The conveying device 3 is preferably a conveyor belt, which is required to withstand continuous high temperature. After the detection switch detects that a preset number of crucibles have accumulated at the entrance of the tunnel furnace 2, it controls the door control device to open. Through the door control device and the detection switch, a batch of crucibles can enter the tunnel furnace 2 for burning. In addition, the operation of the conveying device 3 can also be controlled by PLC timing, and the opening and closing of the door control device can also be controlled.

[0024] In addition, it further includes a temperature control device for controlling the temperature inside the tunnel furnace 2. The temperature inside the furnace can be adjusted through the temperature control device to meet different temperature requirements.

[0025] Furthermore, it further includes a furnace hood 1 for accommodating the tunnel furnace 2, the first rotary dust removal device 4 and the second rotary dust removal device 6. In a distribution mode, the first rotary dust removal device 4 is located at the lower right of the tunnel furnace 2, and the second rotary dust removal device 6 is located at the upper left of the tunnel furnace 2. The furnace hood 1 can prevent the problem of dust scattering during the dust cleaning process.

[0026] Among them, a dust removal fan 9 is provided at the bottom of the furnace hood 1. The dust removal fan 9 is preferably an explosion-proof fan. Specifically, an air inlet is provided on one side of the bottom of the furnace hood 1 close to the storage device 5, and an air outlet is provided on the other side opposite to this side. Through the dust removal fan 9, it can prevent the crucible from taking the dust out of the furnace hood 1.

[0027] In this specification, each embodiment is described in a progressive manner. The key point of each embodiment is to illustrate the differences from other embodiments. For the same or similar parts among the embodiments, reference can be made to each other.

[0028] The above has introduced in detail a crucible automatic cleaning device provided by the present invention. Specific examples are used in this article to elaborate on the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
