A flange connection center centering rotary sealer

Abstract

The invention relates to a flanged connection centring rotation sealer which comprises a sealer baffle, a sealer housing, center sleeve, a gland, filling, locating sleeves, a hole ring and an oil cup, wherein the sealer baffle is in a flanged shape and is fixedly connected with the sealer housing; the sealer housing comprises a hollow pipe part and an elbow part; the locating sleeves are placed in the hollow pipe part of the sealer housing; the center sleeve is located by the locating sleeve and mounted in the hollow pipe part of the sealer housing and can rotate relative to the hollow pipe part of the sealer housing; the filling is mounted between the center sleeve and the hollow pipe part of the sealer housing; the gland is connected with an opening of the hollow pipe part of the sealer housing; the hole ring is located in the hollow pipe part of the sealer housing and mounted outside the center sleeve; the oil cup is mounted on the housing at the hollow pipe part of the sealer housing; and the hole ring is communicated with the oil cup.

Description

technical field [0001] The invention relates to the technical field of solar thermal utilization, in particular to a flange-connected centering rotary sealer. Background technique [0002] Solar thermal power generation technology (English name Concentrating Solar Power, referred to as CSP) uses a concentrator to reflect solar radiation energy to a heat collector, and the heat collector converts solar radiation energy into heat energy, and generates power through a thermal cycle process. As an important way of large-scale solar power generation, solar thermal power generation has a series of obvious advantages. First of all, its carbon emission in the whole life cycle is very low, only 18g / kWh according to foreign research. Secondly, this technology has the lowest cost among the existing solar power generation technologies, and it is easier to quickly realize large-scale industrialization. Finally, solar thermal power generation also has a very strong compatibility advanta...

Problems solved by technology

Because the height and angle of the sun will change in real time, the collector usually needs a rotating device capable of carrying heat transfer oil. Such rotating devices in the prior art usually use bellows to compensate for the position change caused by rotation, but Because the weight of the bellows and oil will cause the stress of the collector tube in the collector, it is easy to cause the pipeline to break and cause oil leakage, which will not only cause pollution accidents, but also increase the labor intensity of workers
