Description

Technical Field

[0001] The utility model relates to the field of SF6 gas recovery, in particular to a SF6 gas cylinder heating and weighing operation device. Background Art

[0002] During GIL maintenance, it is necessary not only to use multiple SF6 cylinders to recover a large amount of SF6 gas (about 550kg) at the same time, but also to complete weighing. The traditional SF6 cylinder shelf cannot keep the bottom of the device basically level with the ground, and the SF6 cylinders can only be moved in and out of the relevant devices by manpower. Not only is the operation difficult and the workload is large, but there is also a risk of cylinders slipping and injuring people. In addition, due to the large amount of heat absorbed by the gasification of liquid SF6, the lower half of the SF6 cylinder cools down and freezes, affecting the cylinder recovery operation. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a SF6 gas cylinder heating and weighing operation device, so that the recovery and filling of SF6 gas is safer, more efficient and more convenient.

[0014] 2) By installing a partition with a heater in the gas cylinder body, it is not only convenient to position the SF6 gas cylinder to prevent it from tipping over, but also the internal space of the gas cylinder body can be divided into different areas, thereby facilitating and accelerating temperature adjustment.

[0015] 3) By installing a hose in the gas cylinder body, the hose is a metal self-sealing hose, which can facilitate the connection between the gas cylinder and the external pipeline, so that the gas in the external pipeline can be diverted into different SF6 gas cylinders.

[0024] like Figure 1-2As shown, a SF6 gas cylinder heating and weighing operation device includes a gas cylinder body 1, a heat preservation door 2 is hinged at the front outer frame of the gas cylinder body 1, the bottom plate of the gas cylinder body 1 is open and covered with rotatable rollers 8, and a slide 3 is hinged on the side of the bottom plate close to the heat preservation door 2. When the slide 3 is opened, the upper end surface forms a slope surface, and the lower end surface is flush with the lower end of the bottom plate. The slope surface of the slide 3 is also covered with rollers 8, which is convenient for pushing the SF6 gas cylinder 4 to roll and move. In addition, slide seats 5 are fixed on the left and right sides of the outer side of the gas cylinder body 1, and the slide seats 5 on each side are arranged up and down. The slide seats 5 on each side include a cross bar, and the two ends of the cross bar are provided with perforations. The upper ends of the two vertical beams in front and behind the bracket 6 pass through the perforations of the slide seat 5 and slide with the slide seat 5. The lower ends of the two vertical beams in front and behind the bracket 6 are installed with running wheels 7, which are convenient for rolling movement. A cross beam is fixed between the lower parts of the two vertical beams before and after the bracket 6, and a lifting cylinder 9 is installed on the cross beam. The piston rod of the lifting cylinder 9 is fixedly connected to the slide seat 5 at the lower end.

[0025] like Figure 5 As shown, when the SF6 gas cylinder 4 needs to be delivered into the gas cylinder vehicle body 1, the lifting cylinder 9 contracts, and the gas cylinder vehicle body 1 descends to the ground. At this time, the lower edge of the running wheel 7 is flush with the bottom of the gas cylinder vehicle body 1. After the thermal insulation door 2 is fully opened, the slide 3 can be turned outward, and the slide 3 remains horizontal. At this time, the SF6 gas cylinder 4 can be slid into the gas cylinder vehicle body 1 along the slide 3 and the roller 8 of the gas cylinder vehicle body 1. In this way, there is no need for manual carrying in and out, which reduces the difficulty and ensures safety.

[0026] When weighing is required, the piston rod of the lifting cylinder 9 is extended to lift the gas cylinder body 1 to a certain height, and then the platform scale 10 can be moved to the bottom of the gas cylinder body 1. The lifting cylinder 9 is partially retracted and the pressure is released, so that the gas cylinder body 1 falls on the platform scale 10 as a whole, thereby facilitating weighing.

[0027] like Figure 1 As shown, preferably, a plurality of partitions 11 are longitudinally arranged in the gas cylinder body 1, and the distance between adjacent partitions 11 matches the diameter of an SF6 gas cylinder 4. A heater 12 is installed in each partition 11, and the heater 12 adopts a conventional electric heating tube. After the heater 12 heats up, the lower half of the SF6 gas cylinder can be prevented from cooling down and freezing. In addition, a temperature sensor is installed at a suitable position in the gas cylinder body 1. The temperature sensor is a thermistor sensor, and the temperature sensor is used to measure the temperature in the gas cylinder body 1. The temperature sensor and the heater 12 are connected to an external temperature controller 13. The temperature controller 13 has a power supply inside. The temperature controller 13 is provided with an adjustment button and a display screen outside. This temperature control system is an existing mature technology, and the temperature is controlled by heating, which will not be described one by one here.

[0028] like Figure 3As shown, preferably, a plurality of groups of hoses 14 are installed on the upper end of the gas cylinder body 1, and the other end of each group of hoses 14 is connected to a main pipe 15, which is fixed by a bracket and one end of which extends out of the gas cylinder body 1. The main pipe 15 is used to be connected to the SF6 gas recovery pipeline for recovering SF6 gas.
