Description

Technical Field

[0001] This invention relates to the field of chemical tools, and more particularly to a volatile-proof, leak-proof sealing component, appliance, and its application. Background Technology

[0002] In the chemical industry, existing reagents such as HNO3, HCl, NaClO, and NH3 are prone to volatilization during storage, and leaks can easily occur at the connection between the storage container and the lid, producing irritating odors in the atmosphere. This phenomenon is especially likely to occur during the handling of storage containers. Therefore, preventing the volatilization of stored reagents is of paramount importance.

[0003] Meanwhile, during the preparation of chemicals such as aqua regia, large amounts of irritating and corrosive volatile gases are easily generated, sometimes accompanied by large amounts of white smoke. These gases overflow from the container and lid connection points, and direct discharge of these volatile gases will pollute the external environment and corrode surrounding objects and equipment. While directly connecting the volatile gases to the exhaust tower duct makes it easy to draw the gases to the tower, the resulting negative pressure in the storage tank exacerbates the evaporation and reduces the efficiency of the working fluid. Furthermore, contact with or inhalation of these volatile gases can cause burns to the skin or respiratory organs, and may even lead to poisoning.

[0004] The patent number "CN207216940U" discloses "a chemical instrument device", but in this patent, it is still necessary to open a part of the opening to add liquid to absorb the internal volatile gas. However, when the opening is opened, there will be a situation where volatile gas overflows, so it cannot completely prevent the overflow of volatile gas. Summary of the Invention

[0005] The purpose of this invention is to provide a sealing component that prevents volatilization and leakage.

[0006] The present invention also provides an appliance with a sealing component that prevents volatilization and leakage.

[0007] The present invention also provides an application of an appliance with a sealing component that prevents volatilization and leakage.

[0008] The innovation of this invention lies in the fact that the volatile gas is introduced into the absorbent liquid in the sealed cavity through the diversion plate, so that the volatile gas after the reaction can be absorbed without opening the sealing cover.

[0009] To achieve the above-mentioned objectives, the technical solution of this invention is as follows:

[0010] A volatile-proof and leak-proof sealing component includes a sealing cap with a drainage plate connected to its bottom surface. Several pressure plates are provided on the drainage plate, located at the bottom outer side of the drainage plate. These pressure plates are used to drain volatile gases into an external sealing cavity, thus improving the sealing effect of the sealing cap. Under the action of the liquid in the external sealing cavity, the pressure plates can push the sealing cap downwards; this allows the liquid level in the sealing cavity to be appropriately lower, only higher than the pressure plates, while also ensuring that the outflow of volatile gases is not affected.

[0011] Furthermore, the bottom surface of the sealing cap is provided with several protrusions, which are located within the inner ring of the drainage plate; the longitudinal cross-section of the protrusions is triangular or arc-shaped. This increases the top area, facilitating the condensation of volatile gases.

[0012] Furthermore, the bottom of the sealing cap is also provided with a sealing wall, which is located outside the drainage plate and bends inward at the bottom. The lower pressure plate is provided with several protrusions to form a sealed cavity with the sealing container; the protrusions on the lower pressure plate can increase the contact area with the solution.

[0013] Furthermore, a sealing ring is provided at the bottom edge of the sealing wall. This facilitates a bottom seal upon contact with the sealed container.

[0014] An appliance with a sealing component that prevents volatilization and leakage includes a sealed container with a top opening, a sealing cap on the top of the sealed container, a sealing cavity outside the sealed container, and a drainage plate located inside the sealing cavity.

[0015] Furthermore, the sealed cavity is provided with a liquid inlet, the sealed container and the sealed cavity are connected and the connection is located inside the guide plate; the sealed cavity is provided with a first liquid inlet, a first liquid outlet and a first overflow outlet; the first overflow outlet is higher than the lowest point of the guide plate, and the sealed container is provided with a second liquid outlet, a water inlet and a second liquid inlet.

[0016] Furthermore, a sealing wall is connected to the sealing cap or the sealing container, and the sealing cavity is formed by the inner wall of the sealing wall, the bottom surface of the sealing cap, and the outer wall of the sealing container; a pH meter is provided inside the sealing cavity.

[0017] Furthermore, when the sealing wall is connected to the sealing cover, a sealing ring is provided at the bottom of the sealing wall.

[0018] Furthermore, the outer wall of the sealed container is provided with a ring of slots facing upwards, and the sealing wall is provided with a ring of insertion holes for inserting into the slots. This results in a superior sealing effect.

[0019] An application of an appliance for preventing volatilization and leakage of sealing components is characterized in that it is used in the preparation of chemical agents that can generate volatile gases, the cleaning of contaminated parts, the storage of chemicals, and chemical reactions; during application, the sealing cavity is filled with absorbent liquid, the liquid level of which is higher than the bottom of the drainage plate, and the volatile gases in the sealed container overflow from the connection and are absorbed by the absorbent liquid.

[0020] An application of an appliance with a volatile-proof and leak-proof sealing component is characterized in that it is used in the preparation of chemical agents that can generate volatile gases, the cleaning of contaminated parts, the storage of chemicals, and chemical reactions;

[0021] When applying:

[0022] (1) The sealed cavity is filled with absorbent liquid, and the liquid level of the absorbent liquid is higher than the bottom of the drainage plate;

[0023] (2) Add solution from several No. 2 liquid inlets. Volatile gas is generated in the sealed container. The volatile gas evaporates into the sealed cavity and is guided to the absorbent liquid in the sealed cavity by the guide plate. After the volatile gas comes into contact with the absorbent liquid in the sealed cavity, it is absorbed by the absorbent liquid. The pH meter in the sealed cavity detects the acidity and alkalinity of the absorbent liquid in the sealed cavity. The pH is adjusted by adding neutralizing liquid through No. 1 liquid inlet, so that the solution in the sealed cavity is safe and non-corrosive.

[0024] (3) After a period of time, most of the solution in the sealed container is drained through the No. 2 drain port, and the draining stops;

[0025] (4) Water overflows into the sealed container. After the sealed container is filled with water, water overflows into the sealed cavity, carrying out the volatile gas that has not been discharged from the sealed container. The volatile gas that has not been discharged is absorbed by the absorbent liquid in the sealed cavity. After the absorbent liquid in the sealed cavity reaches the height of the first overflow port, it begins to overflow from the first overflow port of the sealed cavity. At the same time, the pH meter in the sealed cavity continuously monitors the pH value. The pH is adjusted by adding neutralizing liquid through the first liquid filling port until the pH value is in the range of 6.5~7.5.

[0026] (5) After overflowing for a period of time, stop filling the sealed container with water and drain the water from the sealed container;

[0027] (6) Repeat steps (4) and (5) several times, drain the solution in the sealed cavity through the No. 1 drain port, and open the lid.

[0028] The beneficial effects of this invention are:

[0029] 1. In this invention, to prevent leakage of volatile gases, a diversion plate is set in the sealed cavity, and the liquid level of the absorbent is higher than the lowest end of the diversion plate. Gas leaking from the sealed container is diverted to the absorbent along the diversion plate. Unabsorbed liquid is sealed in a closed space formed by the diversion plate and the lower pressure plate, the L-shaped diversion component, the cover, and the liquid surface. Finally, the gas in the closed space is absorbed, dissolved, and discharged by the circulating supply of absorbent.

[0030] 2. In this invention, by setting a lower pressure plate on the drainage plate, the absorbent liquid applies downward pressure to the lower pressure plate, thereby improving the sealing effect of the sealing cap. Attached Figure Description

The sealed cavity 8 is equipped with a first liquid inlet 8.2, a first overflow port 8.1, and a first drain port 8.3. A pH meter is installed inside the sealed cavity. The first overflow port 8.1 is higher than the lowest point of the guide plate 2. The sealed container 7 is equipped with a second drain port 7.2, a water inlet 7.3, and a second liquid inlet 7.4.

[0044] Example 4: An appliance with anti-evaporation and leak-proof sealing components includes a sealed container 7 with a top opening, a sealing cap 1 at the top of the sealed container 7, a drainage plate 2 connected to the bottom surface of the sealing cap 1, several pressure plates 3 on the drainage plate 2, the pressure plates 3 located outside the drainage plate 2 and at the bottom of the drainage plate 2, several protrusions 5 on the bottom surface of the sealing cap 1, the protrusions 5 located in the inner ring of the sealed container 7; the longitudinal cross-section of the protrusions 5 is triangular, a sealing cavity 8 is provided outside the sealed container 7, the drainage plate 2 is located in the sealing cavity 8, the sealing cavity 8 is provided with a liquid inlet 8.1, the sealed container 7 and the sealing cavity 8 are connected through an air outlet 7.1 located on the sealing container 7, the air outlet 7.1 is located at the drainage plate. A sealing wall 6 is connected to the sealing cap 1, a sealing ring 9 is provided at the bottom of the sealing wall 6, and the sealing cavity 8 is formed by the inner wall of the sealing wall 6, the bottom surface of the sealing cap 1 and the outer wall of the sealed container 7. The outer wall of the sealed container 7 has a ring of slots 7.2 facing upwards, and the sealed wall 6 has a ring of insertion ports 6.2 for inserting into the slots 7.2. The sealed cavity 8 has a first liquid inlet 8.2, a first overflow port 8.1, and a first drain port 8.3, and a pH meter is installed inside the sealed cavity; the first overflow port 8.1 is higher than the lowest point of the guide plate 2. The sealed container 7 has a second drain port 7.2, a water inlet 7.3, and a second liquid inlet 7.4.

[0045] When used to prepare disinfectant: Close the sealing cap 1, and inject water into the sealed container 7 through the water inlet 7.3. Continue injecting water until the sealed container 7 is full and overflows into the sealed cavity 8. Stop injecting the absorbent solution when overflowing begins at overflow port 8. Drain the water from the sealed container 7 through drain port 7.2. Inject sodium hypochlorite and water at a ratio of 1:200 into the sealed container 7 through the two fill ports 7.4 to form the prepared solution. The sodium hypochlorite in the sealed container begins to evaporate. After contacting the water in the sealed cavity 8, the sodium hypochlorite is absorbed by the water. The pH meter in the sealed cavity 8 measures the acidity or alkalinity of the water. Neutralization solution is added through fill port 8.2 to adjust the pH, ensuring the solution in the sealed cavity 8 is safe and non-corrosive. The sealed container 7... Drainage port 7.2 discharges most of the prepared solution into the storage tank, then stops the discharge. Water overflows from sealed container 7. Once sealed container 7 is full, water overflows into sealed cavity 8, carrying away any undischarged sodium hypochlorite. This undischarged sodium hypochlorite is absorbed by the water in sealed cavity 8. Once the water in sealed cavity 8 reaches the height of overflow port 8.1, it begins to overflow from overflow port 8.1. Simultaneously, the pH meter in sealed cavity 8 continuously monitors the pH value, and neutralizing solution is added through filling port 8.2 to adjust the pH until it is within the range of 6.5 to 7.5. After overflowing for a period of time, water filling to sealed container 7 is stopped, and the water in sealed container 7 is drained. After several cycles of circulation and cleaning, the lid can be opened.

[0046] Example 5: An appliance with a sealing component to prevent volatilization and leakage includes a sealed container 7 with a top opening. A sealing cap 1 is provided on the top of the sealed container 7. A drainage plate 2 is connected to the bottom surface of the sealing cap 1. Several pressure plates 3 are provided on the drainage plate 2, located on the outer side and bottom of the drainage plate 2. Several protrusions 5 are provided on the bottom surface of the sealing cap 1, located within the inner ring of the sealed container 7. The longitudinal cross-section of the protrusions 5 is triangular. A sealing cavity 8 is provided outside the sealed container 7. The drainage plate 2 is located within the sealing cavity 8. A liquid inlet 8.1 is provided on the sealing cavity 8. The sealed container 7 and the sealing cavity 8 are connected through an outlet 7.1 located on the sealing container 7, at the drainage plate. A sealing wall 6 is connected to the sealed container 7. The sealing cavity 8 is formed by the inner wall of the sealing wall 6, the bottom surface of the sealing cap 1, and the outer wall of the sealed container 7. The sealed cavity 8 is equipped with a first liquid inlet 8.2, a first overflow port 8.1, and a first drain port 8.3. A pH meter is installed inside the sealed cavity. The first overflow port 8.1 is higher than the lowest point of the guide plate 2. The sealed container 7 is equipped with a second drain port 7.2, a water inlet 7.3, and a second liquid inlet 7.4.

[0047] When used for cleaning contaminated parts: During cleaning, open the sealing cap 1, place the contaminated quartz part into the sealing container 7, close the sealing cap 1, and inject clean water into the sealing container 7 through the water inlet 7.3. Continue injecting water until the set time is reached. At this time, the sealing container 7 is full of water and overflows into the sealing cavity 8, and the sealing cavity 8 begins to overflow from the first overflow port 8.1. Drain the clean water from the sealing container 7 through the second drain port 7.2, and add the cleaning solution through the second filling port 7.4. The cleaning solution corrodes the contaminants on the surface of the quartz part. During the cleaning process, the volatile gases are highly corrosive and irritating. The volatile gases in the sealing container 7 begin to evaporate. After the volatile gases come into contact with the water in the sealing cavity 8, they are absorbed by the absorbent liquid. At this time, the water gradually becomes acidic. The pH meter in the sealing cavity 8 detects that the solution in the sealing cavity 8 is acidic. Alkali solution is added through the first filling port 8.2 to ensure that the solution in the sealing cavity 8 is safe and non-corrosive. After the set cleaning time, most of the solution in sealed container 7 is drained through drain port 7.2. Drainage stops. Some volatile gases are trapped in the absorbent liquid in sealed cavity 8 by the guide plate 2, preventing them from escaping from sealed container 7. At this point, water is added to sealed container 7 to overflow. After sealed container 7 is full, water overflows into sealed cavity 8, allowing the remaining volatile gases to be absorbed by the absorbent liquid in sealed cavity 8. Once the solution in sealed cavity 8 reaches a certain height, it begins to overflow from overflow port 1. Simultaneously, the pH meter in sealed cavity 8 continuously monitors the pH value, adding alkalinity through fill port 8.2 to adjust the pH until it is within the range of 6.5 to 7.5. After the overflow time is limited, water is added to sealed container 7, and the solution is drained. After drainage stops, clean water is added until the set time is reached, and then the solution in sealed container 7 is drained again. This cycle is repeated multiple times to complete the cleaning of the quartz component. At this point, the solution inside the sealed cavity 8 is drained, and the quartz piece is removed from the sealed cavity 8.

[0048] Example 6: Application of an appliance with a volatile and leak-proof sealing component, used in the preparation of chemical agents that can generate volatile gases, the cleaning of contaminated parts, the storage of chemicals, and chemical reactions; during application, the sealing cavity 8 is filled with absorbent liquid, the liquid level of which is higher than the bottom of the drainage plate 2, and the volatile gas in the sealing container 7 overflows from the connection and is absorbed by the absorbent liquid.

[0049] Example 7: Application of an appliance with a volatile and leak-proof sealing component, used in the preparation of chemical agents that can generate volatile gases, the cleaning of contaminated parts, the storage of chemicals, and chemical reactions;

[0050] In application: The sealed cavity 8 is filled with absorbent liquid, and the liquid level is higher than the bottom of the drainage plate 2. Solution is added through several No. 2 inlet ports 7.4. Volatile gas is generated in the sealed container 7 and evaporates into the sealed cavity 8. This evaporated gas is then drained by the drainage plate 2 into the absorbent liquid in the sealed cavity 8. Upon contact with the absorbent liquid in the sealed cavity 8, the volatile gas is absorbed. A pH meter in the sealed cavity 8 detects the acidity or alkalinity of the absorbent liquid. Neutralizing liquid is added through No. 1 inlet port 8.2 to adjust the pH, ensuring the solution in the sealed cavity 8 is safe and non-corrosive. After a period of time, most of the solution in the sealed container 7 is drained through No. 2 outlet port 7.2, and drainage is stopped. Water is then added to the sealed container 7 to overflow. After the sealed container 7 is filled with water, water overflows into the sealed cavity 8, carrying away the volatile gases that have not yet been discharged from the sealed container 7. These volatile gases are then absorbed by the absorbent liquid in the sealed cavity 8. Once the absorbent liquid in the sealed cavity 8 reaches the height of the first overflow port 8.1, it begins to overflow from the first overflow port 8.1. At the same time, the pH meter in the sealed cavity 8 continuously monitors the pH value and adds neutralizing liquid through the first liquid inlet 8.2 to adjust the pH until the pH value is within the range of 6.5 to 7.5. After overflowing for a period of time, the filling of the sealed container 7 is stopped, and the water in the sealed container 7 is drained. After several cycles of circulation and cleaning, the solution in the sealed cavity 8 is drained through the first drain port 8.3, and the lid is opened.
