Description

Technical Field

[0001] The utility model relates to the technical field of water seal structure equipment, in particular to a water seal structure for a storage tank manhole. Background Art

[0002] The water seal is a measure that uses a certain height of hydrostatic pressure to resist the change of air pressure in the drainage pipe and prevent the gas in the pipe from entering the room. The water seal structure is not only used in the building drainage pipe, but also set at the feed pipe mouth of the heating and mixing equipment to achieve the purpose of sealing. In daily life, the seal of the kimchi jar mouth also adopts the water seal structure. However, the existing water seal structure is not equipped with a water replenishment device. Due to the high temperature in the heating and mixing equipment or the high external temperature, the water in the water tank evaporates and dissipates, and the water tank cannot be replenished in time. The water level in the water tank drops, resulting in poor sealing of the water seal structure.

[0003] The application number is CN202121057520.8, which discloses an emergency water device for the water seal tank on the top of a dry coke quenching furnace, including a water seal tank and a water storage tank. The water storage tank is provided with an upper pipeline and a lower pipeline connected to the water seal tank, a full flow pipe manual regulating valve is provided on the upper pipeline, a water tank manual regulating valve and a water seal tank manual valve are provided on the lower pipeline, a cold water pipe is provided between the water tank manual regulating valve and the water seal tank manual valve, a water supply one-way valve is provided on the cold water pipe, and a venting hole is provided on the top of the water storage tank. The utility model can realize the water storage function under normal conditions and the emergency function under abnormal conditions. It can effectively alleviate the problems of high-temperature burning and leakage of the water seal tank, overflow of harmful gases, high danger of artificial water replenishment operations, and easy freezing and loss of emergency function in cold winter weather. It has a simple structure, convenient operation, low manufacturing and maintenance costs, and can effectively reduce labor costs and safety risks.

[0004] The water seal trough emergency water device disclosed in the above document has the following defects: during the use of the device, when the water source in the device needs to be discharged, the device controls the regulating valve to make the drain pipe drain the water. When water needs to be connected, it is necessary to install a water seal trough through a water pipe. This structure cannot quickly drain water in or out, thereby reducing the processing efficiency of the mixing equipment.

[0005] It can be seen from this that the existing water seal tank emergency water device does not have the function of rapid drainage, and it is necessary to improve the existing deficiencies and provide a function that can quickly drain water and deliver water. Utility Model Content

[0006] The utility model aims to provide a water seal structure for a storage tank manhole to solve the problems raised in the above-mentioned background technology.

[0007] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0008] The utility model relates to a water seal structure for a manhole of a storage tank, which comprises a water seal tank and a fixing structure.
