Description

Technical Field

[0001] The utility model relates to the field of explosion-proof refueling, in particular to a skid-mounted explosion-proof refueling device. Background Art

[0002] A skid-mounted refueling device is a device used for refueling and filling. The skid-mounted refueling device has the characteristics of simple structure, convenient operation, safety and reliability, etc., and is suitable for places such as small gas stations and store refueling points. It can improve refueling efficiency, reduce labor and energy costs, and ensure the safe filling of fuel.

[0003] The biggest characteristic and advantage of the skid-mounted refueling device is that it is convenient for installation and movement. The product is widely applicable to large construction sites such as logistics parks, ports, docks, airports, mines, and internal gas stations of enterprises. In these areas, due to traffic restrictions, large oil tank trucks are difficult to enter, so it is not suitable to build large gas stations. Therefore, the skid-mounted refueling device has been greatly utilized. The skid-mounted refueling device can store oil, refuel, and meet the fuel use of internal transportation tools. And if it is in a large construction site, it can also be relocated along with the construction site to ensure that the construction equipment can be refueled in time.

[0004] In the existing skid-mounted refueling device, the fuel dispenser is connected to the whole device, resulting in inconvenient refueling.
