Description
Technical Field
[0001] This utility model relates to the field of water seal device technology, and specifically discloses a low-pollution water seal structure suitable for multiple scenarios in normal pressure environments. Background Technology
[0002] In industrial fields such as chemical processing, hazardous materials storage, and environmental protection, atmospheric pressure equipment or containers (such as storage tanks, reaction vessels, and wastewater pools) often need to use water seal structures to isolate the internal gas from the external environment.
[0003] In industrial production and material storage, the handling and protection of volatile substances are crucial. Traditional water seal structures often use a trough-shaped cover to fit a ring-shaped water tank, which has significant drawbacks: First, the excessive contact area between the water and the internal gas in the tank leads to a large amount of volatile substances being lost through evaporation, causing environmental pollution; second, the lack of an effective drainage design allows condensed liquid to easily flow into the ring-shaped water tank through the cover, polluting the water, weakening the water seal effect, and even posing safety hazards. Therefore, a low-pollution water seal structure suitable for various scenarios under normal pressure is needed to solve this problem. Utility Model Content

[0009] A drain cone is disposed at the center of the inner top of the water seal cover, and its bottom is connected to the root of the brim.

Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.
[0023] Please see Figure 1-2 A low-pollution water seal structure suitable for various scenarios in normal pressure environments, including
[0024] Water tank 3 has an outer ring 1 and an inner ring 2 arranged coaxially. The outer ring 1 and the inner ring 2 are fixed by welding. The height of the outer ring 1 is higher than that of the inner ring 2.
[0025] Water seal cover 7, the bottom of water seal cover 7 is provided with a downward extending brim 4, the outer wall of the brim 4 is tightly fitted with the inner wall of the inner ring 2 of the water tank to form a sealing contact point 5;
[0026] The water seal 6 is formed by the brim 4 and the contact point 5, and the water level does not exceed the contact point 5.
[0027] The drain cone 8 is located at the center of the inner top of the water seal cover 7, and its bottom is connected to the root of the brim 4.
[0028] In this embodiment: the water tank 3 adopts a split structure, with the outer ring 1 having a height of 8-12 cm and the inner ring 2 having a height of 5-8 cm, and is fixed by welding to ensure sealing. The water seal cover 7 is manufactured by mold stamping process, with the cap 4 fitting against the inner ring 2 of the water tank to form a sealing contact point 5. The drain cone 8 is connected to the center of the top inside the water seal cover 7, and its bottom is fixed to the root of the cap 4. In use, the water tank 3 is installed on the equipment or container, and after placing the water seal cover 7, the seal is achieved by gravity. When the water level rises to the contact point 5 between the cap 4 and the inner ring 2 of the water tank, an effective water seal 6 is formed. The design of the outer ring 1 being higher than the inner ring 2 of the water tank effectively prevents liquid overflow and external structural corrosion, improving the stability of the water seal.
[0029] The brim 4 fits tightly against the inner ring 2 of the water tank, and the water seal cover 7 achieves a seal by its own weight, which greatly reduces the contact area between water and internal gas, and reduces the volatilization loss of volatile substances and environmental pollution.
[0030] The structure of the drain cone 8 guides the condensate backflow, preventing contamination of the water in the water tank 3, maintaining the water seal effect and reducing safety risks.
[0031] The overall structure is compatible with a variety of volatile substances (such as sticky substances, toxic and harmful gases, flammable and explosive gases, etc.), and is suitable for multiple scenarios such as chemical industry, storage, and environmental protection, taking into account both sealing performance and the need for frequent opening.
[0032] As a technical optimization of this utility model, the angle between the brim 4 and the horizontal ground is about 60 degrees, and the contact angle between the brim 4 and the inner wall of the inner ring 2 of the water tank is about 30 degrees.
[0033] In this embodiment: when manufacturing the water seal cap 7 and the brim 4, the angle between the brim 4 and the horizontal ground is precisely controlled to be 60 degrees, and the contact angle with the inner wall of the inner ring 2 of the water tank is 30 degrees, through the die stamping process. This angle design ensures that the sealing contact point 5 is located in the longitudinal middle position of the brim 4, ensuring uniform distribution of gravity and reliable sealing. The 60-degree angle of the brim 4 facilitates the flow of condensate along the slope, achieving efficient drainage in conjunction with the drain cone 8; the 30-degree contact angle makes the brim 4 fit more tightly with the inner ring 2 of the water tank, improving pressure resistance.
[0034] As a technical optimization of this utility model, the sealing contact point 5 is located at the middle position of the longitudinal height of the brim 4.
[0035] In this embodiment, the sealing contact point 5 is located in the middle of the cap brim 4, so that the gravity of the water seal cover 7 is evenly applied to the sealing surface, thereby improving the sealing stability and durability.
[0036] As a technical optimization of this utility model, the diameter of the water seal cover 7 is smaller than the diameter of the inner ring 2 of the water tank.
[0037] In this embodiment, the diameter of the water seal cover 7 is smaller than that of the inner ring 2 of the water tank, ensuring that the brim 4 can penetrate deep into the inner ring 2 of the water tank and fit tightly, avoiding interference or jamming, and facilitating the placement and removal of the water seal cover 7, thus improving the ease of operation.
[0038] As a technical optimization of this utility model, the diameter of the drain cone 8 is smaller than the diameter of the water seal cover 7.
[0039] In this embodiment: by making the diameter of the drain cone 8 smaller than that of the water seal cover 7, interference with the internal space of the water seal cover 7 is avoided, ensuring that the condensate flows smoothly back into the container along the surface of the drain cone 8, reducing liquid retention, and preventing secondary pollution and material loss.
[0040] As a technical optimization of this utility model, the water seal cover 7 is provided with an observation hole and a handle 9.
[0041] In this embodiment: the observation hole is made of 304 stainless steel with a thickness of 1-2 mm, which takes into account strength, corrosion resistance and lightweight, and makes it easy to view the internal condition of the container in real time. The substance status can be monitored without opening the lid, reducing the risk of volatilization; the design of the handle 9 makes the water seal cover 7 easy to lift and place, improving the efficiency of operation.
[0042] As a technical optimization of this utility model, the main components of the water seal structure are made of stainless steel.
[0043] In this embodiment: Stainless steel is corrosion-resistant, has high strength, is suitable for toxic, harmful or corrosive environments, and extends its service life.
[0044] The working principle and usage process of this utility model are as follows: The water tank 3 is fixedly installed on the opening of the equipment or container, and an appropriate amount of water is injected into the water tank 3. Then, the water seal cover 7 is placed, with its brim 4 extending into the inner ring 2 of the water tank. Under the weight of the water seal cover 7 itself, the outer wall of the brim 4 fits tightly against the inner wall of the inner ring 2 of the water tank, forming a ring-shaped mechanical seal contact point.
[0045] When the internal air pressure of the container approaches equilibrium with the external atmospheric pressure, the water level in the water tank 3 will rise. The water level will reach the sealing contact point 5, forming a sealed "water seal ring" between the cap 4 and the inner ring 2 of the water tank. This water seal 6 effectively prevents the gas inside the container from escaping and also prevents external air from entering. The water seal 6 acts only as a final barrier, significantly reducing the contact surface area between the water and the gas inside the container. This fundamentally inhibits the dissolution and volatilization of volatile substances through the water medium. The condensate generated inside the equipment will drip onto the inclined surfaces of the drain cone 8 and the water seal cover 7. Thanks to the guiding effect of the drain cone 8 and the 60-degree tilt design of the cap 4, the condensate is guided back into the container along the inclined surfaces, preventing it from dripping directly into the water tank 3 and contaminating the sealing water, thus maintaining the purity and sealing effectiveness of the water seal liquid.

Therefore, they should not be construed as limitations on this utility model.
[0047] However, the above description is only a specific embodiment of this utility model and should not be construed as limiting the scope of implementation of this utility model. Therefore, any substitution of equivalent components or equivalent changes and modifications made in accordance with the scope of protection of this utility model should still fall within the scope of the claims of this utility model.
