Description

Technical Field

[0001] This utility model relates to the field of filling equipment technology, specifically to a filling device for a natural gas-to-ethylene glycol flare device. Background Technology

[0002] Ethylene glycol is an important chemical raw material widely used in textiles, plastics, rubber, pharmaceuticals, and other fields. With the continuous growth of China's economy, the demand for ethylene glycol has been increasing year by year, driving the rapid development of the natural gas-to-ethylene glycol industry. This, in turn, prompts continuous improvement of related filling equipment technology to meet production needs. However, existing filling equipment is prone to detachment at the connection point with the external conduit, leading to raw material leakage, environmental pollution, and safety hazards. At the same time, the liquid level in the storage tank needs to be monitored in real time during the filling process. If the liquid level in the storage tank is too low, subsequent filling processes may not be able to proceed normally, or even damage related equipment. To solve the above problems, a filling device for a natural gas-to-ethylene glycol flare unit is needed.

[0003] The existing filling device for a natural gas-to-ethylene glycol flare unit cannot monitor the liquid level of the alcohol-containing liquid in the storage tank in real time during operation. When the liquid level is too high, material overflow is likely to occur. When the liquid level is too low, subsequent filling processes may not be able to proceed normally, or even damage related equipment. During the filling process, the connection with the external conduit is easily pulled or collided by external forces, causing it to detach and leak internal raw materials. This not only affects the filling operation, but also pollutes the environment and causes safety accidents. Therefore, there is an urgent need for a filling device for a natural gas-to-ethylene glycol flare unit. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a filling device for a natural gas-to-ethylene glycol flare unit, in order to solve the problems of existing natural gas-to-ethylene glycol flare unit filling devices, which cannot monitor the liquid level of the alcohol-containing liquid in the storage tank in real time. When the liquid level is too high, material overflow is likely to occur. When the liquid level is too low, subsequent filling processes may not be able to proceed normally, or even damage related equipment. During the filling process, the connection with the external conduit is easily pulled or collided by external forces, causing it to fall off and leak internal raw materials. This not only affects the filling operation, but also pollutes the environment and causes safety accidents.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a filling device for a natural gas-to-ethylene glycol flare unit, comprising a base, a fixing frame mounted on the top of the base, a storage tank mounted on the top of the fixing frame, a viewing window on the side wall of the storage tank, a lifting lug mounted on the top of the storage tank, a liquid level sensor mounted on the top of the storage tank, an infrared detection port mounted on the bottom of the liquid level sensor, a limit rod mounted on the bottom of the liquid level sensor, a fixing sleeve mounted on the outer wall of the limit rod, a hollow float mounted on the outer wall of the fixing sleeve, a check valve mounted on the side wall of the storage tank, a pressure gauge mounted on the top of the check valve, a clamping sleeve mounted on the side wall of the check valve, a clamping groove formed on the inner wall of the clamping sleeve, an external conduit mounted on the outer wall of the check valve, a positioning block mounted on the outer wall of the external conduit, a positioning rod mounted on the outer wall of the positioning block, and a positioning sleeve mounted on the outer wall of the positioning rod.

[0006] Preferably, the mounting bracket is welded to the storage tank, and the liquid level sensor is connected to the flange of the storage tank.

[0007] Preferably, the fixing sleeve is movably connected to the limiting rod, and the hollow float is vertically arranged with respect to the infrared detection port.

[0008] Preferably, the external conduit is sleeved with the check valve, and the positioning rod is symmetrically arranged with the central axis of the external conduit as the center.

[0009] Preferably, the positioning rod is engaged with the sleeve, and the positioning sleeve is threadedly connected to the positioning rod.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. This utility model uses a storage tank, a viewing window, a liquid level sensor, an infrared detection port, a limit rod, a fixing sleeve, and a hollow float. The liquid level sensor is connected to the top flange of the storage tank. The hollow float will float up and down with the liquid level in the storage tank, while the infrared detection port will emit infrared rays that illuminate the top of the hollow float. The liquid level is monitored in real time by the distance between the infrared rays and the top of the hollow float. When the liquid level is abnormal, an alarm is immediately issued to prevent the liquid level from being too high, which could easily cause material overflow, or too low, which could cause subsequent filling processes to fail or even damage related equipment.

[0012] 2. This utility model, through the design of a ferrule, a slot, an external conduit, a positioning block, a positioning rod, and a positioning sleeve, allows the external conduit connecting the flare device to the side wall of the storage tank during filling operations. Then, the positioning rod is rotated to engage with the ferrule. Finally, the positioning sleeve is threaded onto the positioning rod, and after tightening, it engages with the slot to prevent the positioning rod from falling off. The combined use of the positioning rod and the positioning sleeve increases the stability of the connection between the storage tank and the external conduit. Attached Figure Description
