Description

Technical Field

[0001] The utility model relates to the technical field of blast furnace ironmaking, in particular to a blast furnace iron ditch material distribution device. Background Art

[0002] Currently, due to the increasing requirements for quality, output, and consumption in blast furnace ironmaking, specific materials need to be added to the molten iron in an open environment before it is filled into the tank. For example, sodium carbonate powder is added to the iron flow channel for desulfurization of the molten iron; an insulating covering agent is added to the swinging nozzle for insulation of the molten iron; and small-sized slag steel is added to the iron flow channel for solid waste recycling. Due to the high temperature of the molten iron channel, accidents are prone to occur when people work close to the molten iron channel. However, all of the above operations currently require people to use tools such as shovels to throw materials into the molten iron channel. This process causes molten iron to splash and is accompanied by huge dust. There are problems with low safety, low efficiency, and high pollution, and improvements are urgently needed. Therefore, we propose a blast furnace iron channel material addition device. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] Example 1, as Figure 1-3As shown, the utility model provides a technical solution: a blast furnace iron ditch material feeding device, including a belt conveyor mechanism 1, an inclined vibrating feeding mechanism 2 and an iron ditch feeding mechanism 3, the belt conveyor mechanism 1 includes a conveyor belt 104 that feeds upward at 25° and a motor 101 and a driving roller 103 that drive the conveyor belt to operate, the inclined vibrating feeding mechanism 2 includes an inclined bucket 202 that feeds downward at 25° and a vibration motor 203 that drives the inclined bucket 202 to vibrate, the inclined vibrating feeding mechanism 2 also includes an inclined baffle A204 arranged below the bottom end of the inclined bucket 202, and the iron ditch feeding mechanism 3 includes an inclined baffle B305 symmetrically arranged with the inclined baffle A204, and an electric push rod 302 that drives the inclined baffle B305 to move horizontally.

[0019] In a specific embodiment of the present invention, the conveyor belt 104 is driven by two driving rollers 103, and the driving rollers 103 are rotatably matched with the bracket 102 through the shaft. The motor 101 is installed on one side of the bracket 102 at the low point of the conveyor belt 104. The motor 101 is connected to the driving rollers 103 at the low point of the conveyor belt 104 through a reducer. The motor 101 drives the conveyor belt 104 to operate through the driving rollers 103;

[0020] The vibration motor 203 is in contact with the back of the inclined bucket 202. Four springs 201 and spring supports are provided on the back of the inclined bucket 202. The springs 201 are used to enhance the vibration effect. The spring supports are used to connect the inclined vibration blanking mechanism 2 to the base. One side of the base is connected to the inclined baffle A204.

[0021] The inclined baffle A204 and the inclined baffle B305 are symmetrically distributed on the left and right. The inclined baffle is composed of a vertical plate and an inclined plate. The bottom of the inclined plate of the two inclined baffles is in contact with each other (such as Figure 1 As shown), the electric push rod 302 is connected to the inclined baffle B305 through the heat insulation plate 304, and the inclined baffle B305 is controlled to move horizontally to perform the blanking operation. A polished rod is also provided on one side of the inclined baffle B305, and the polished rod is slidably fitted with the through hole of the through hole plate 303. The motor 101, the vibration motor 203 and the electric push rod 302 are all powered by the power cord and the power supply, and their start and stop operations are controlled by an independent controller.

[0022] In the preferred technical solution, a number of ridges 105 are evenly spaced on the outer surface of the conveyor belt 104, and the distance between two adjacent ridges is set to 10 cm. The provision of ridges is beneficial to reducing the rolling and sliding of materials and making it more convenient to convey materials.

[0023] In the preferred technical solution, the highest point of the inclined bucket 202 is close to directly below the highest point of the conveyor belt 104, which is conducive to receiving the material transported by the highest point of the conveyor belt 104. Side guards are provided on both sides of the inclined bucket 202 to prevent the material from sliding and being lost from both sides of the inclined bucket 202.

[0024] In the preferred technical solution, a spring mechanism is provided on the bottom surface of the inclined bucket 202. The spring mechanism includes a spring 201 and a spring support. The spring support is fixed to the surface of the base.

[0025] In the preferred technical solution, one end of the inclined baffle A204 is fixed to one end of the base by bolts. The slope of the inclined surface of the inclined baffle A204 is 10° greater than the slope of the inclined surface of the inclined bucket 202, which is conducive to smoother and faster material discharge of the inclined baffle A204.

[0026] In the preferred technical solution, the iron ditch feeding mechanism 3 also includes an L-shaped support 301, a through-hole plate 303 is fixed on the top of the L-shaped support 301, the electric push rod 302 is fixed at the center position of the through-hole plate 303, and the inclined baffle B305 is fixed with an insulation plate 304 on the side facing the through-hole plate 303. The push rod of the electric push rod 302 is connected to the insulation plate 304, and the insulation plate 304 is used to isolate the electric push rod 302 from the inclined baffle B305.

[0027] Working principle: The materials required for the iron ditch are transported through the belt conveyor mechanism 1. The conveyor belt 104 with ridges 105 is more convenient for transporting materials. The materials at the highest point of the conveyor belt 104 naturally fall to the surface of the inclined bucket. The materials are vibrated by the inclined bucket and discharged to the bottom of the slope of the two inclined baffles. The bottom of the slope of the two inclined baffles is located just above the center of the iron ditch 4 (such as Figure 1 、 3 As shown in the figure, the electric push rod controls the separation of the two inclined baffles to ensure the safe addition of materials into the iron ditch. When no material is being conveyed, the two inclined baffles are in a closed state to protect the inclined vibrating unloading mechanism. Both the belt conveyor mechanism and the inclined vibrating unloading mechanism are open structures, which is convenient for subsequent cleaning. Workers only need to put materials at the low point of the belt conveyor mechanism, which greatly improves personnel safety.
