Metal rubber composite compensation dustproof device with sealing structure

Abstract

The invention discloses a metal rubber composite compensation dustproof device with a sealing structure, and relates to the technical field of compensation and sealing, a first connecting end and a second connecting end are respectively provided with a first guide cylinder and a second guide cylinder which extend towards the inner side, the second guide cylinder is located on the outer side of the first guide cylinder, and the second guide cylinder and the first guide cylinder are coaxially installed in a crossed manner; a first gap is formed between the first sealing ring and the second sealing ring, and a lip-shaped sealing ring is connected into the first gap in a sealed mode. A corrugated compensation pipe is fixedly connected between the first connecting end and the second connecting end and located on the outer side of the second guide cylinder, and a second gap is formed between the corrugated compensation pipe and the second guide cylinder. The first flow guide cylinder and the second flow guide cylinder which are coaxial and are installed in a crossed mode are matched with the corrugated compensation pipe on the outermost side, a first gap is reserved between the first flow guide cylinder and the second flow guide cylinder, and a second gap is reserved between the corrugated compensation pipe and the second flow guide cylinder. The first gap and the second gap ensure relative movement with large displacement in a three-dimensional space when the first gap and the second gap are vibrated.

Description

technical field [0001] The invention relates to the technical field of compensation and sealing, in particular to a metal-rubber composite compensation and dustproof device with a sealing structure. Background technique [0002] In the steelmaking plants of iron and steel enterprises, there are still many problems in the overall or individual compensation connection parts of the converter mineral material or mineral powder conveying system, such as leakage loss of alloys, vibration dust, compensation failure, etc. Once the compensation sealing function fails, it will be This will lead to the loss of granular powder alloys, resulting in inaccurate proportions of raw materials such as alloy materials, resulting in changes in the composition of molten steel, and even serious product quality problems, which directly affect the use level and economic benefits of the product. It is common for steel mills to be downgraded by customers every year due to product quality, which invisi...

Problems solved by technology

However, due to the influence of their own structures and materials, existing pipeline compensation devices such as metal bellows compensators, non-metallic compensators, sleeve compensators, and square compensators are not suitable for large displacements, large angles, and high-frequency vibrations. Therefore, it is impossible to meet the technical requirements for sealing compensation of the feeder mouth of the vibrating feeder for steelmaking alloy blanking
