Description

Technical Field

[0001] This patent relates to the field of storage devices, specifically a protective slag decarbonization device. Background Technology

[0002] Currently, when testing the viscosity, surface tension, and other properties of finished protective slag, it is required to remove the carbonaceous material (referred to as "decarbonization"). Otherwise, the accuracy of the measured properties will be affected. The principle of decarbonization is to oxidize the carbonaceous material in the protective slag into carbon monoxide or carbon dioxide at high temperatures. Therefore, the conditions required for decarbonization are suitable high temperature and sufficient oxygen or air. Considering that if the temperature is too low, the reaction rate will be slow; if the temperature is too high, the protective slag may sinter or even partially melt, thus encapsulating the carbonaceous material and isolating it from air or oxygen, making it impossible to remove. Therefore, the temperature is generally controlled at 600-800℃.

[0003] However, existing protective slag storage devices still have some shortcomings. For example, existing decarbonization devices are mainly unidirectional furnaces or muffle furnaces, which mostly use a fixed stirring position for stirring, which can easily lead to certain stirring dead zones inside. Therefore, existing technologies need to be improved. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this patent is to provide a protective slag decarbonization device.

[0005] The technical solution adopted by this patent to solve its technical problem is: a protective slag decarbonization device, including a protective slag furnace body, wherein support blocks are uniformly and equidistantly assembled on the outer ring of the top of the protective slag furnace body, and an annular slide rail is installed at the lower inner end of the support block.

[0006] A slider is installed on the annular slide rail, a support frame is installed on the side wall of the slider, and a lifting block is installed inside the support frame;

[0007] A motor is installed on the side wall of the lifting block, a rotating shaft is assembled at the drive end of the motor, and a bearing seat is assembled on the outside of the rotating shaft.

[0008] The outside of the rotating shaft is equipped with a stirring auger;

[0009] An annular top ring is installed at the upper inner end of the support block, and the inner wall of the annular top ring is provided with internal teeth.

[0010] A motor b is mounted on the top of the support block, and a gear is assembled on the drive end of the motor b, which meshes with internal teeth.

[0011] Furthermore, an electric push rod is mounted on the top of the support frame, and the lifting block is connected to the drive end of the electric push rod.

[0012] Furthermore, both outer walls of the lifting block are provided with sliding surfaces, which are fitted into the inner wall of the support frame.

[0013] Furthermore, the bearing housing includes two opposing shaft cylinders a and b, with rotating cavities evenly formed on the inner walls of shaft cylinders a and b, and ball bearings installed inside the rotating cavities.

[0014] Furthermore, connecting plates are installed on both side walls of shaft cylinder a and shaft cylinder b, and threaded holes are opened on the side walls of the connecting plates. Bolts are screwed into the threaded holes, and fixing plates are installed on the rear side walls of shaft cylinder a and shaft cylinder b.

[0015] Furthermore, the outer walls of the shaft cylinders a and b are provided with oil injection holes, and plugs are inserted into the oil injection holes.

[0016] Furthermore, the inner wall of the protective slag furnace body is equipped with a heating plate, and the bottom end of the protective slag furnace body is equipped with a discharge pipe.

[0017] The beneficial effects of this patent are:

[0018] A protective slag decarbonization device is simple in structure and easy to operate. By setting an annular slide rail at the top of the protective slag furnace body, the overall stirring height of the stirring shaft can be changed, which further ensures the stirring effect of the protective slag furnace body during use. Moreover, the stirring shaft moves with the sliding block, which can effectively avoid the stirring dead corners inside. Attached Figure Description
