Description

Technical Field

[0001] This utility model belongs to the field of oil mist emission separation technology, specifically relating to a sealing device for loading and unloading barrels. Background Technology

[0002] Existing container loading and unloading systems on the market lack sealing devices at the gas and liquid container openings, resulting in several drawbacks during loading and unloading. Specifically: For some volatile substances, unsealed loading and unloading processes lead to significant evaporation. This results in material waste and, moreover, the reduced concentration of the evaporated substance may affect its usability. Unsealed loading and unloading processes cannot prevent the entry of oxygen, moisture, and microorganisms from the air. Microorganisms can grow and multiply on the contents of the container, causing mold, spoilage, and other problems. External dust and impurities can easily enter the container, contaminating the stored substances. If the container contains corrosive or toxic liquids, such as strong acids, strong alkalis, or pesticides, unsealed loading and unloading processes may lead to leakage and environmental pollution. When containerizing flammable or explosive substances, the evaporating gases from unsealed loading and unloading processes, when mixed with air and reaching a certain concentration, may ignite or cause a fire upon contact with open flames or static electricity.

[0003] Existing container loading and unloading devices on the market often fail to ensure the plumb line reaches the bottom of the container during unloading, resulting in incomplete unloading. Incomplete unloading means that some materials are not fully utilized, leading to resource waste. If the remaining material is flammable, explosive, toxic, or hazardous, uncleaned containers after unloading may pose a safety hazard. Incompletely unloaded containers require additional processing steps, such as cleaning and recycling, which increases operating costs for businesses. If the remaining material differs from the raw materials or products to be used next, it may cause raw material contamination, leading to substandard product quality.

[0004] Existing container loading and unloading systems on the market may fail to completely clean residual substances from the vertical pipes during the unloading process, potentially leading to the following hazards: If these residues are released into the environment, they can pollute soil, water, and air. If subsequent products are incompatible with the residues, they may mix into the new products, causing a decline in product quality. If the residues are flammable or explosive chemicals, such as gasoline, alcohol, or other organic solvents, they may volatilize and form flammable gases during subsequent loading and unloading operations. If these gases encounter static electricity, sparks, or other ignition sources, they can easily ignite a fire or even an explosion, causing serious injury to personnel and equipment. Utility Model Content

[0005] The purpose of this utility model is to provide a sealing device mechanism for loading and unloading barrels, so as to solve the problems of poor sealing at the gas and liquid phase vertical pipes and difficulty in removing residual liquid from the vertical pipes.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A sealing device for loading and unloading barrels includes a liquid phase support pipe with a sight glass embedded in it. The device is characterized by: a support frame mounted on the liquid phase support pipe; a gas phase hose mounted on the support frame; a gas phase rigid pipe mounted on the gas phase hose; a gas phase sealing base mounted on the gas phase rigid pipe; a liquid phase vertical pipe connected to the liquid phase support pipe via a rotary joint; a ball valve mounted on the liquid phase vertical pipe; a rotating ring platform fitted onto the liquid phase vertical pipe, allowing rotation; a downward-pressing locking hook mounted on the rotating ring platform; and a liquid phase sealing base mounted on the liquid phase vertical pipe.

[0008] Furthermore, the downward locking hook includes a hook bracket, a tension handle, and a tension hook. The hook bracket is bolted to the rotating ring, a pin is installed between the hook bracket and the tension handle, and the tension hook is installed on the tension handle via an adjusting nut.

[0009] Furthermore, the liquid phase sealing seat includes a seat body, a sealing cover plate, a liquid phase handle, and a spring support barrel. The seat body is equipped with an O-ring and a skeleton sealing ring. The sealing cover plate is connected to the seat body via connecting bolts. The liquid phase handle is mounted on the sealing cover plate. The spring support barrel is installed on the sealing cover plate via fastening bolts. The sealing cover plate is designed with hooks; one end of the spring is connected to the hook, and the other end of the spring is equipped with a tension hook. The sight glass structure of this invention ensures reliable visual monitoring throughout the loading and unloading process, guaranteeing operational safety. The ball valve structure of this invention allows for controllable on / off switching during operation, ensuring operational safety.

[0010] Furthermore, the vapor phase sealing base is equipped with an O-ring and a vapor phase handle. The ergonomic design of the handle facilitates installation, disassembly, and adjustment, greatly enhancing the user experience.

[0011] Furthermore, a gas phase limiting bolt is installed on the gas phase rigid pipe, and a liquid phase limiting bolt is also installed on the liquid phase vertical pipe.

[0012] This utility model has the following advantages:

[0013] The liquid-phase sealing seat designed in this utility model features an O-ring seal on the outer side of the gas-phase sealing base, which tightly fits the threaded area at the root of the barrel opening, effectively preventing material leakage during loading and unloading. The skeleton seal structure inside the seat can meet the requirements of rotary sealing and axial movement sealing of the vertical pipe, ensuring a good seal at the vertical pipe while effectively removing residual liquid from it.

[0014] This utility model's design features a liquid phase sealing seat and a downward-pressing locking hook that work together to ensure the liquid phase pipeline reaches the bottom of the container. Simultaneously, a specially designed diversion port at the bottom of the liquid phase pipeline minimizes material residue at the bottom of the container during unloading. The rotating platform can rotate 360 ​​degrees on the vertical pipe to accommodate the uncertain angle of the tension hook during tightening, ensuring perpendicular force on the tension hook at any angle. The tension hook's height can also be adjusted using a nut to meet operational and usage requirements. The spring structure design allows for flexible adjustment of the tension force as needed.
