Detailed Description
The present application is described in further detail below with reference to figures 1-3.
The embodiment of the application discloses a sensor for a ladle scale weighing system.
Referring to fig. 1 and 2, a sensor for a ladle scale weighing system comprises a bottom plate 4, a resistance strain gauge 1 is arranged at the top end of the bottom plate 4, a weighing sensor 2 is arranged at the top end of the resistance strain gauge 1, and a bearing plate 3 for bearing a measured object is arranged at the top end of the weighing sensor 2. Specifically, weighing sensor 2 is high temperature sensor, and high temperature sensor's heat-resisting effectual is difficult to appear measuring inaccurate or the condition that fails when being in the higher environment of temperature and takes place. The top end of the bottom plate 4 is fixedly provided with a protective frame 5, the bottom plate 4 is a ceramic fiber nano heat insulation plate, and the protective frame 5 is machinable microcrystalline mica ceramic. The ceramic fiber nano heat insulation plate and the processable microcrystalline mica ceramic are both heat insulation materials, so that the floor and the protective frame 5 are not easy to melt by high-temperature molten steel, and a certain heat insulation effect is achieved. The resistance strain gauge 1 is arranged in the protective frame 5, and the cross section of the protective frame 5, the weighing sensor 2 and the bearing plate 3 is circular. The shape of the protective frame 5 is bowl-shaped, and the inner diameter of the protective frame 5 is larger and larger from top to bottom. First annular opening 6 has been seted up on the top of protection frame 5, and second annular opening 7 has been seted up to the bottom of protection frame 5, and the diameter of first annular opening 6 is less than the diameter of second opening. The lateral wall of bearing plate 3 is laminated mutually with the inboard wall of protective frame 5, and the bottom of bearing plate 3 is less than the top of protective frame 5. The fixed cover in top of bearing plate 3 lateral wall is equipped with ring baffle 10, and the one end that this ring baffle 10 kept away from bearing plate 3 is less than the one end that ring baffle 10 is close to bearing plate 3, and the external diameter of ring baffle 10 is greater than the diameter of first annular opening 6.
In operation, when the high-temperature molten steel in the ladle drops to the edge of the bearing plate 3, the annular baffle plate 10 is arranged to prevent the high-temperature molten steel from flowing into the annular baffle plate 10 from the gap between the bearing plate 3 and the protective frame 5, so that the high-temperature molten steel is prevented from damaging the resistance strain gauge 1 and the weighing sensor 2 in the protective frame 5. High-temperature molten steel flows onto the protective frame 5 along the annular baffle 10, and because the outer side wall of the bowl-shaped protective frame 5 has a certain radian, the high-temperature molten steel can flow downwards along the edge of the protective frame 5, so that the high-temperature molten steel is prevented from stopping on the protective frame 5 for a long time to cause higher temperature inside the protective frame 5, and inaccurate measurement or failure of the resistance strain gauge 1 inside the protective frame 5 is prevented.
Referring to fig. 1 and 2, in order to make the high-temperature molten steel slide off the protective frame 5 more quickly, a plurality of drainage grooves 8 are formed in the outer side wall of the protective frame 5 from top to bottom, and the drainage grooves 8 are uniformly distributed along the circumferential direction of the protective frame 5.
