Description

Technical Field

[0001] This application relates to the field of ultrapure chemical loading technology, specifically a special container for ultrapure high-purity ammonia water. Background Technology

[0002] There are many types of packaging barrels on the market, including imported brands such as Merrill Lynch, Integrity, and Sekisui. However, they all share a common problem: for ammonia, the phenomenon of expansion in summer and contraction in winter cannot be effectively solved. Over time, the alternating changes in thermal expansion and contraction greatly reduce the service life of the barrels. Furthermore, the frequent wrinkling of the inner lining seriously affects the quality of the stored products, and the bottom tube may even break in winter.

[0003] Secondly, the best quality buckets currently available on the market can only hover around G5, which cannot reliably provide or reflect the quality of the products. Summary of the Invention

[0004] The purpose of this application is to provide a special tank for ultra-clean high-purity ammonia water, so as to at least partially solve the technical problem in the above-mentioned background technology that the service life of the tank is greatly reduced due to the alternating changes of thermal expansion and contraction.

[0005] To achieve the above objectives, this application provides the following technical solution: a special tank for ultra-clean, high-purity ammonia water, comprising,

[0006] The barrel body includes a corrugated buffer layer and a filling layer in sequence along the vertical direction. The corrugated buffer layer can extend or retract along the vertical height of the barrel body. The filling layer is lined with a clean layer in the part that contacts the material. A discharge port is provided at the top of the barrel body.

[0007] A bottom insertion tube is installed inside the barrel body, with one end extending into the bottom of the barrel body and the other end connected to the discharge port at the top of the barrel body.

[0008] Furthermore, the corrugated buffer layer is located at the top of the barrel body, and the area ratio of the corrugated buffer layer to the filling layer is 1:9.

[0009] Furthermore, the cleanroom layer is made of high-density polyethylene.

[0010] Furthermore, the cleanroom layer is made of modified high-density polyethylene, which can chelate metal ions in the material.

[0011] Furthermore, a liquid-drawing device is provided at the bottom of the insertion tube, and the liquid-drawing device is sleeved on the bottom of the insertion tube, with several liquid-drawing holes evenly distributed on the liquid-drawing device.

[0012] Furthermore, the liquid extractor is arranged in a hollow cylindrical shape.

[0013] Furthermore, the bottom of the liquid extractor is 1-2 mm away from the bottom of the container.

[0014] Furthermore, the barrel body is made of high-density polyethylene.

[0015] Furthermore, the discharge port is embedded in the upper top of the barrel body.

[0016] Compared with the prior art, the beneficial effects of this application include at least the following:

[0017] The ultra-clean, high-purity ammonia water container provided in this application includes a container body and a bottom insertion pipe. The container body includes a corrugated buffer layer and a filling layer arranged vertically. The corrugated buffer layer can extend or contract along the vertical height of the container body. The filling layer, in contact with the material, is lined with a clean layer. A discharge port is provided at the top of the container body. The bottom insertion pipe is located inside the container body, with one end extending to the bottom of the container body and the other end connected to the discharge port at the top of the container body. The corrugated buffer layer of this device can expand and contract, preventing damage caused by frequent folding of the container body. Simultaneously, the clean layer prevents direct contact between the inner wall of the container and the material, thus avoiding material contamination. The bottom insertion pipe allows for complete emptying of the material inside the container. Attached Figure Description

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] This application provides a special container for ultra-clean, high-purity ammonia water, combined with... Figure 1The container includes a barrel body 1 and a bottom insertion tube 6. The barrel body 1 contains a corrugated buffer layer 2 and a material filling layer 3 arranged vertically inside the barrel body 1. The corrugated buffer layer 2 can extend or retract along the vertical height of the barrel body 1. The material filling layer 3 is lined with a clean layer 4 in the part that contacts the material. The top of the barrel body 1 is provided with a discharge port 5. The bottom insertion tube 6 is disposed inside the barrel body 1, with one end of the bottom insertion tube 6 extending into the bottom of the barrel body 1 and the other end of the bottom insertion tube 6 communicating with the discharge port 5 at the top of the barrel body 1.

[0023] External temperature changes cause variations in the solubility of ammonia in ammonia water. When the temperature is too high, the dissolved ammonia in the ammonia water volatilizes, leading to increased pressure inside the ammonia water tank, causing the tank walls to bulge and posing a risk of leakage. This special ammonia water tank has a corrugated buffer layer 2 at its top. This corrugated buffer layer 2 expands or contracts with changes in internal pressure, effectively preventing the tank walls from bulging or contracting due to thermal expansion and contraction, thus reducing its service life. Simultaneously, a cleanroom layer 4 is lined inside the tank, effectively preventing the tank body 1 from releasing ions and contaminating the high-purity ammonia water after prolonged contact. Furthermore, a grounding pipe 6 is installed, effectively solving the problem of incomplete material removal from conventional tanks.

[0024] In one embodiment, it should be noted that most companies typically load high-purity ammonia into the barrel to 80% of its capacity. The corrugated buffer layer 2 is located at the top of the barrel 1, and the area ratio of the corrugated buffer layer 2 to the loading layer 3 is 1:9, allowing the high-purity ammonia to be loaded normally into the loading layer 3.

[0025] In one embodiment, the clean layer 4 is made of high-density polyethylene. The clean layer 4 comes into contact with ammonia water, which can effectively prevent impurities in the barrel 1 from precipitating into the high-purity ammonia water and causing product contamination.

[0026] In one embodiment, the clean layer 4 is made of modified high-density polyethylene. The modified high-density polyethylene material can chelate metal ions in the material and can slowly adsorb metal ions in high-purity ammonia water, which is beneficial for removing impurities from high-purity ammonia water.

[0027] In one embodiment, a liquid-collecting device 7 is provided at the bottom of the insertion tube 6. The liquid-collecting device 7 is sleeved on the bottom of the insertion tube 6, and a plurality of liquid-collecting holes are evenly distributed on the liquid-collecting device 7.

[0028] In one embodiment, the liquid collector 7 is arranged in a hollow cylindrical shape.

[0029] In one embodiment, the bottom of the liquid extractor 7 is 1-2 mm away from the bottom of the inner wall of the barrel 1, which is beneficial for sucking out the material at the bottom of the barrel.

[0030] In one embodiment, the barrel body 1 is made of high-density polyethylene.

[0031] In one embodiment, the discharge port 5 is embedded in the upper top of the barrel body 1.
