Description

Technical Field

[0001] The utility model relates to the technical field of refining slag production equipment, and specifically relates to a pre-melted refining slag proportioning weighing machine. Background Art

[0002] Pre-melted refining slag is made by sintering and melting limestone (containing CaO), magnesite (containing MgO), dolomite (containing CaO·MgO), witherite (containing BaO) and fluorite (containing CaF2) in a cupola. This kind of slag has a very low melting point, can melt at the fastest speed, shortens the residence time of molten steel in the refining ladle, and strengthens the smelting process. At the same time, the fluidity of this kind of refining agent is very good, optimizing the kinetic conditions of the desulfurization reaction, and deep desulfurization can be achieved. When producing pre-melted refining slag, a special weighing device is needed to weigh various raw materials and use them in proportion.

[0003] For example, the Chinese patent publication number is CN216726855U, and the technical solution disclosed in this patent document is as follows: a pre-melted refining slag proportioning weighing machine, including a bottom plate. A stirring device support frame is fixedly installed on the top of the bottom plate. A stirring and mixing box is installed on the stirring device support frame through bearings. A gear ring is sleeved outside the stirring and mixing box. A stirring motor is installed on the left side of the stirring device support frame through a motor installation bin. The output shaft of the stirring motor is fixedly installed with a gear, and the gear meshes with the gear ring. A weighing device installation frame is fixedly installed on the top of the stirring device support frame. A weighing device and a diversion device are fixedly installed on the weighing device installation frame. A lifting gantry is fixedly installed on the top of the bottom plate. An ingredient box group is slidably installed on the lifting gantry through a chute and a lifting slider. After proportioning and weighing, this device can directly stir and mix the materials, and the mixed materials are directly transported to the slag refining furnace through a feeding conveyor belt, which can effectively save the intermediate transfer link and improve work efficiency.

[0004] The above-mentioned technical ingredients flow into the inner box of the weighing device through a diversion plate. However, when the ingredients inside the inner box of the weighing device reach the standard, the ingredients on the diversion plate need to flow a certain distance, resulting in the subsequent ingredients continuing to flow into the inner box of the weighing device after reaching the weighing standard, which will cause the weight to exceed the standard and affect the proportioning accuracy.

By setting the electric push rod 72, the support plate 74 can be driven to move back and forth. A through hole 75 is opened on the support plate 74. A limit frame 76 is fixedly installed on the top of the collection box 77, and the limit frame 76 is arranged on the top of the support plate 74. The collection box 77 passes through the through hole 75 and is movably connected with the through hole 75. By setting the limit frame 76, it is convenient to install the collection box 77 on the support plate 74. A discharge pipe 8 is communicated on the right side of the weighing tank 6. A cylinder 11 is fixedly installed on the top of the discharge pipe 8. The output end of the cylinder 11 is fixedly installed with a fixing plate 10. A baffle 9 is fixedly installed at the bottom of the fixing plate 10. By setting the cylinder 11, the baffle 9 can be driven to move up and down, so as to control the opening and closing of the discharge pipe 8.

[0026] In this embodiment, by starting the cylinder 11 to drive the fixing plate 10 to move upward, the fixing plate 10 drives the baffle 9 to move upward a certain distance to open the discharge pipe 8, so that the weighed batching flows into the mixing tank 12. When the amount of batching flowing out of the weighing tank 6 reaches the specified ratio, the cylinder 11 drives the baffle 9 to close the discharge pipe 8, and the excess batching in the weighing tank 6 remains in the weighing tank 6. Start the electric push rod 72 to drive the support plate 74 to move forward, so that the collection box 77 is aligned with the discharge pipe 8, and then move the baffle 9 upward to collect the excess batching into the collection box 77, making the ratio of raw materials more accurate.
