FIG. 1 is a schematic view of a slag sample taking device for a furnace door of a steelmaking arc furnace according to an embodiment of the utility model;
in the figure, an angle control line 1, a first handle 2, a fixed ring 3, a second handle 4, a 5U-shaped bracket, a 6 supporting rod and a 7 sampling box are arranged.
Detailed Description
The utility model is described in further detail below with reference to the embodiments of the drawings.
As shown in fig. 1, a slag sample sampling device for a furnace door of a steelmaking electric arc furnace in the embodiment comprises a hand-held handle, wherein one end of the hand-held handle is provided with a U-shaped bracket 5 with an opening arranged outwards. The support rod 6 is erected at the opening of the U-shaped support 5, and two ends of the support rod 6 are respectively hinged with the U-shaped support 5, so that the support rod 5 can freely rotate on the U-shaped support 5. The support rod 6 is hinged with a sampling box 7, and the sampling box 7 freely rotates on the support rod 6. The mounting position of the support rod 6 is arranged at a distance of 2/5 of the top of the sampling box 7, namely, the support rod is arranged on the upper part of the sampling box, and the sampling box is in a free state, so that the opening of the sampling box faces upwards. The sampling box bottom is provided with an angle control mechanism, and the angle control mechanism pulls the sampling box bottom to enable the sampling box to rotate outwards, so that the rotation angle of the sampling box is adjusted, and the angle between the opening of the sampling box and the slag sample to be taken is adjusted.
The length of the sampling box is greater than the interval between the support rod and the U-shaped bracket.
The sampling box 7 is a cuboid with an opening at the top and a sealed bottom, the opening is wedge-shaped, and the height of the opening close to the outer side of the U-shaped bracket is higher than that of the opening at the inner side of the U-shaped bracket, namely, the opening is high at the outer side and low at the inner side.
The hand-held handle comprises a first handle 2 and a second handle 4,U type bracket 5 which are fixed on a second handle 4, wherein the second handle is fixed on one end of the first handle, and the horizontal included angle between the first handle and the second handle is 30 degrees.
