Description

Technical Field

[0001] The utility model relates to the technical field of pneumatic filling, in particular to a pneumatic filling device for a four-tube reduction furnace. Background Art

[0002] The function of the reduction furnace is to reduce metal oxides into metals. It is usually used to refine steel, ferroalloys, manganese alloys, etc. The reduction reaction requires high temperature, high pressure and a certain reducing agent. The reduction furnace plays an important role in it. By burning fuel, high temperature and high pressure gas flow is generated to transport the reducing agent to the surface of the material to reduce the oxides into metals. Therefore, the structure of the reduction furnace and the design of the control system are crucial to the effective reduction reaction.

[0003] Traditional filling equipment usually lacks the function of precise control and adjustment of reduction furnaces at different heights. For example, a fixed filling mechanism can often only work at a certain height, and it is difficult to flexibly cope with furnaces at different heights. Therefore, there is a problem of inconvenience in adjusting the height of the discharge port. Utility Model Content

The adjusting mechanism 3 also includes a groove rod 303 fixedly connected to the outer surface of the storage bin 207, and the outer surface of the sliding frame 304 is fixedly connected to the sliding block 305, and the outer surface of the sliding block 305 is slidably connected to the outer surface of the groove rod 303. The sliding block 305 allows the sliding frame 304 to slide along the outer surface of the groove rod 303, which is convenient for limiting the sliding frame 304, wherein the upper surface of the mobile cart 1 is fixedly connected to the cylinder 302, and the inner wall of the cylinder 302 is slidably connected to the piston rod 306, and the upper end of the piston rod 306 is fixedly connected to the lower surface of the discharge frame 301.

[0025] It is worth mentioning that the piston rod 306 can drive the discharge frame 301 to slide up and down along the direction of the groove rod 303 through the cylinder 302, thereby facilitating the filling of the four-tube reduction furnace at different heights.

[0026] In order to control the amount of raw materials, the filling mechanism 2 also includes an air compressor 205 fixedly connected to the upper surface of the mobile cart 1, and the output port of the air compressor 205 is fixedly connected to a pipe 206, and the other end of the pipe 206 extends to the inner wall of the storage bin 207. By starting the air compressor 205, the air compressor 205 transmits the compressed gas to the storage bin 207, so that the sliding plate 208 can slide on the inner wall of the storage bin 207, so that the raw materials above the sliding plate 208 can overflow from the discharge port, wherein the storage bin A transparent plate 202 is embedded in the outer surface of the storage bin 207, and scale lines 201 are engraved on the outer surface of the storage bin 207.

The transparent plate 202 and the scale line 201 make it easy to observe the amount of raw materials in the storage bin 207.

[0028] Working principle: By starting the air compressor 205, the air compressor 205 delivers compressed air to the storage bin 207, so that the air can push the sliding plate 208 upward, and then the sliding plate 208 drives the raw materials to move upward, and the raw materials are discharged from the discharge port opened on the outer surface of the storage bin 207 and fall into the sliding frame 304, and fall into the discharge frame 301 under the action of gravity, so as to facilitate the addition of raw materials to the four-tube reduction furnace, and the piston rod 306 can slide up and down through the cylinder 302. The sliding of the piston rod 306 drives the discharge frame 301 and the sliding frame 304 to slide on the outer surface of the groove rod 303, and at the same time, the sliding block 305 slides on the outer surface of the groove rod 303, so as to prevent the sliding frame 304 and the storage bin 207 from separating, so as to facilitate the filling of the four-tube reduction furnace at different heights.
