Description

Technical Field

[0001] This utility model relates to the field of hazardous liquid packaging technology, and in particular to a chemical packaging bottle. Background Technology

[0002] Electronic grade phosphorus oxychloride is a colorless and transparent liquid, mainly used in semiconductor and photovoltaic doping. It is a colorless and transparent chemical that is highly corrosive, highly oxidizing, toxic, and reacts violently with water. When using phosphorus oxychloride, it is placed in a quartz glass source bottle and then carried to the user's process pipeline by nitrogen gas. The quartz glass source bottle is connected to the nitrogen gas inlet and outlet pipes through a valve on it.

[0003] A search revealed a Chinese patent application with patent number CN201922467861.1, which discloses a quartz source bottle that prevents liquid accumulation. The bottle includes a bottle body and a valve body. The valve body is sealed to the bottle mouth. A valve core is horizontally installed inside the valve body. One end of the valve core extends out of the valve body and has a handle on it. However, the above technical solution does not have a corresponding structure that allows nitrogen to directly enter the bottom of the quartz source bottle. Therefore, the nitrogen entering the bottle cannot quickly and fully mix with phosphorus oxychloride, resulting in phosphorus oxychloride not being able to be continuously and stably output through nitrogen. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a chemical packaging bottle.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A chemical packaging bottle includes a quartz glass source bottle. An outlet pipe and an inlet pipe are fixed to the top outer wall of the quartz glass source bottle. The outlet pipe and the inlet pipe pass through the top outer wall of the quartz glass source bottle. An insertion pipe is fixed to the bottom end of the inlet pipe. Four evenly distributed vent holes are opened at the bottom end of the insertion pipe 20 mm away from the bottom inner wall of the quartz glass source bottle. The inner diameter of the vent holes is 2 mm.

[0007] As a further improvement of this utility model: an air outlet valve is provided on the outer wall of the air outlet pipe, and an air inlet valve is provided on the outer wall of the air inlet pipe.

[0008] As a further improvement of this utility model, the outer walls of the air outlet pipe and the air inlet pipe are respectively provided with mounting ring grooves.

[0009] As a further improvement of this utility model, the bottom opening of the insertion tube is 10mm away from the inner wall of the bottom of the quartz glass source bottle.

[0010] As a further improvement of this utility model, the inner diameter of both the air intake pipe and the insertion pipe is 5mm.

[0011] As a further improvement of this utility model, the height of the air outlet pipe and the air inlet pipe is 40mm.

[0012] As a further improvement of this utility model: the diameter of the quartz source bottle is 180mm, the height of the quartz source bottle is 260mm, and the outer wall thickness of the quartz source bottle is 6.5mm.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. When the user needs to use the phosphorus oxychloride stored inside the quartz glass source bottle, nitrogen gas can be introduced into the inlet pipe through the inlet valve. The nitrogen gas enters the insertion pipe through the inlet pipe, and then is evenly sprayed into the bottom of the quartz glass source bottle through the bottom opening of the insertion pipe and the four exhaust holes at the bottom of the insertion pipe. This allows the nitrogen gas to fully and evenly contact the phosphorus oxychloride stored inside the quartz glass source bottle. Due to the volatility of phosphorus oxychloride, the phosphorus oxychloride gas is carried by the nitrogen gas into the outlet pipe, and then transported to the photovoltaic diffusion furnace pipeline through the outlet valve on the outer wall of the outlet pipe. This allows the phosphorus oxychloride stored inside the quartz glass source bottle to be effectively and evenly and stably released outward through the nitrogen gas introduced inside, thereby improving the uniformity and stability of the phosphorus oxychloride gas entering the semiconductor photovoltaic diffusion furnace and improving the utilization rate of the stored phosphorus oxychloride.

[0015] 2. A corresponding sealing ring can be installed on the inner wall of the installation ring groove to improve the stability and sealing of the connection between the air outlet pipe, air inlet pipe, air outlet valve, and air inlet valve; by setting a quartz glass source bottle with uniform wall thickness and smooth outer wall, the overall stability and structural strength of the quartz glass source bottle can be improved, allowing users to reuse the quartz glass source bottle multiple times, thereby improving the economic and environmental benefits of the quartz glass source bottle.

[0024] Example 1

[0025] A chemical packaging bottle, such as Figure 1-3 As shown, it includes a quartz glass source bottle 1. An exhaust pipe 2 and an inlet pipe 4 are fixed to the top outer wall of the quartz glass source bottle 1. The exhaust pipe 2 and the inlet pipe 4 pass through the top outer wall of the quartz glass source bottle 1. An insertion pipe 6 is fixed to the bottom end of the inlet pipe 4. Four evenly distributed exhaust holes 8 are opened at the bottom end of the insertion pipe 6 20mm away from the bottom inner wall of the quartz glass source bottle 1. The inner diameter of the exhaust holes 8 is 2mm.

[0026] An air outlet valve 3 is provided on the outer wall of the air outlet pipe 2, and an air inlet valve 5 is provided on the outer wall of the air inlet pipe 4.

[0027] The outer walls of the air outlet pipe 2 and the air inlet pipe 4 are respectively provided with mounting ring grooves 7;

[0028] The bottom opening of the insertion tube 6 is 10mm away from the inner wall of the bottom of the quartz source bottle 1;

[0029] The inner diameter of both the intake pipe 4 and the insertion pipe 6 is 5mm;

[0030] The height of the air outlet pipe 2 and the air inlet pipe 4 is 40mm;

[0031] The quartz glass source bottle 1 has a diameter of 180 mm, a height of 260 mm, and an outer wall thickness of 6.5 mm.

[0032] After phosphorus oxychloride is packaged in a quartz glass source bottle 1, the user can directly move the quartz glass source bottle 1 to the corresponding processing position for use. When the user needs to use the phosphorus oxychloride inside the quartz glass source bottle 1, nitrogen gas can be introduced into the inlet pipe 4 through the inlet valve 5. The nitrogen gas enters the insertion pipe 6 through the inlet pipe 4, and then is evenly sprayed into the bottom of the quartz glass source bottle 1 through the bottom opening of the insertion pipe 6 and the four exhaust holes 8 set at the bottom of the insertion pipe 6. This allows the nitrogen gas to fully and evenly contact the phosphorus oxychloride stored inside the quartz glass source bottle 1. Due to the volatility of phosphorus oxychloride, it can be carried by the nitrogen gas into the outlet pipe 2, and then enter the corresponding processing conveying pipeline through the outlet valve 3 on the outer wall of the outlet pipe 2. This allows the phosphorus oxychloride stored inside the quartz glass source bottle 1 to be effectively and evenly released outward through the nitrogen gas introduced inside, thereby ensuring that the phosphorus oxychloride gas entering the photovoltaic diffusion furnace tube is uniform and stable, improving the doping effect. Improve the utilization rate of phosphorus oxychloride stored inside quartz source bottle 1;

[0033] Meanwhile, a corresponding sealing ring can be set on the inner wall of the mounting ring groove 7 to improve the stability and sealing of the connection between the air outlet pipe 2, the air inlet pipe 4, the air outlet valve 3, and the air inlet valve 5.

[0034] By setting the quartz glass source bottle 1 with uniform wall thickness and smooth outer wall, the overall stability and structural strength of the quartz glass source bottle 1 can be improved, thereby allowing users to reuse the quartz glass source bottle 1 multiple times and improving the economic and environmental benefits of the quartz glass source bottle 1.

[0035] In this embodiment, the quartz glass source bottle 1, the outlet pipe 2, the inlet pipe 4, and the insertion pipe 6 are all made of quartz glass.

[0036] Working principle: Nitrogen gas is introduced into the inlet pipe 4 through the inlet valve 5. The nitrogen gas enters the insertion pipe 6 through the inlet pipe 4, and then is evenly sprayed into the bottom of the quartz source bottle 1 through the bottom opening of the insertion pipe 6 and the four exhaust holes 8 set at the bottom of the insertion pipe 6. This allows the nitrogen gas to fully contact the phosphorus oxychloride stored inside the quartz glass source bottle 1. Due to the volatility of phosphorus oxychloride, it can enter the outlet pipe 2 under the carry of nitrogen gas. Then, it enters the corresponding processing pipeline through the outlet valve 3 on the outer wall of the outlet pipe 2.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
