Description

TECHNICAL FIELD

[0001] The utility model relates to a red phosphorus processing device, especially to a low-temperature quenching device for electronic grade red phosphorus crushing. BACKGROUND

[0002] High-purity red phosphorus is used for manufacturing semiconductor materials, such as compound semiconductor indium phosphide, gallium phosphide, and ion implantation agent for semiconductor silicon.

[0003] High-purity red phosphorus products are obtained by crushing after yellow phosphorus is converted into high-purity red phosphorus ingots. The existing crushing technology mainly adopts mechanical extrusion crushing, such as the red phosphorus crushing devices disclosed in patents CN218784853U, CN217725693U, and CN216322449U. Red phosphorus is a flammable and explosive product. In the process of crushing red phosphorus, the heat generated by the crushing equipment itself and the internal energy generated by the impact of red phosphorus may cause combustion or other accidents. Therefore, inert gas needs to be introduced into the crushing equipment to isolate air. After crushing is completed, red phosphorus is discharged from the crushing equipment, and red phosphorus inevitably contacts air. Therefore, the crushing equipment needs to be cooled before discharging red phosphorus. During reprocessing, inert gas needs to be continuously introduced into the crushing equipment, resulting in low efficiency of the entire processing flow. SUMMARY

[0004] In order to overcome the above-mentioned defects of the prior art, the utility model aims to provide a safe and efficient low-temperature quenching device for electronic grade red phosphorus crushing.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

[0006] A low-temperature quenching device for electronic grade red phosphorus crushing includes a red phosphorus collector and a low-temperature quenching tank. The red phosphorus collector includes a basket and a collection tank in the basket. The low-temperature quenching tank includes a tank body containing a cooling medium. The tank body has a neck and a neck plug that fits the neck. The red phosphorus collector is buckled to the neck by the basket to suspend the collection tank in the tank body.

[0007] Preferably, the cooling medium in the tank body is liquid nitrogen.

[0008] Preferably, the tank body is provided with an inner container, and the tank body is provided with a vacuum sealing joint.

[0009] Preferably, the tank body is provided with a handle near the neck.

[0010] Preferably, the tank body is provided with a bottom support.

[0011] Preferably, the depth of the red phosphorus collector in the tank body is greater than one-third of the height of the tank body.

[0012] Preferably, the top diameter of the basket is greater than one-third of the neck diameter but less than the neck diameter.

[0013] Preferably, the collection tank has a cylindrical structure with several holes on its outer wall.

[0014] Compared with the prior art, this utility model places the blocky red phosphorus in a low-temperature quenching tank through a red phosphorus collector. The red phosphorus is fully quenched by liquid nitrogen, which changes its physical properties and makes it easy to break into uniform and dense 2-5mm particles, greatly improving the conversion rate, quality and production efficiency of electronic-grade red phosphorus products.

[0017] The structure of this utility model will now be fully described in conjunction with specific embodiments so that those skilled in the art can fully understand and implement it.

[0018] like Figure 1 As shown, the present invention discloses a low-temperature quenching device for crushing electronic-grade red phosphorus, including a red phosphorus collector 1 and a low-temperature quenching tank.

[0019] in,

[0020] The red phosphorus collector 1 includes a basket 11 and a collection tank 12 located inside the basket 11.

[0021] The low-temperature cold extraction tank includes a tank body 2 containing a cooling medium, which in this embodiment is liquid nitrogen; the top of the tank body 2 is provided with a neck opening 21 and a neck plug 22 adapted to the neck opening 21; the red phosphorus collector 1 is fastened to the neck opening 21 by the basket 11 so that the collection tank 12 is suspended in the tank body 2.

[0022] In this embodiment, by placing the blocky red phosphorus in the collection tank 12, and then placing the collection tank 12 into the tank body 2 of the low-temperature cold extraction tank through the basket 11, the physical shape of the red phosphorus changes after being fully quenched by liquid nitrogen, making it easier to break into uniform and dense particles, which can reach 2-5mm. This greatly improves the finished product conversion rate, quality and production efficiency of electronic-grade red phosphorus, and the equipment has a simple structure and is easy to operate.

[0023] Further, the tank body 2 is provided with an inner liner 23, the cooling medium is contained in the inner liner 23, and the tank body 2 is provided with a vacuum sealing connector 24.

[0024] Preferably, the tank body 2 is provided with a handle 25 near the neck 21. The device is more easily carried and moved by lifting the handle 25.

[0025] Preferably, the tank body 2 is provided with a bottom support 3. The device is placed stably by the bottom support 3, improving the use effect.

[0026] As known from the above, the depth of the red phosphorus collector 1 in the tank body 2 directly affects the cold quenching effect of the red phosphorus. Preferably, the depth of the red phosphorus collector 1 in the tank body 2 is greater than one third of the height of the tank body 2.
