Description

Technical Field

[0001] This utility model relates to the field of material conveying technology, and in particular to a small weighing hopper feeding device for ore bins. Background Technology

[0002] In blast furnace production, the charging system is a crucial auxiliary system, primarily supplying coke and ore to the blast furnace. A malfunction in this system directly impacts blast furnace operation. After ore screening, qualified ore falls through a small hopper onto a large conveyor belt, which then transports it to the main conveyor belt for blast furnace smelting. The existing small hopper discharge port is a constricted flared opening, with its end perpendicular to the large conveyor belt. This results in significant impact force from the ore on the belt, posing a risk of damage. Furthermore, the impact of the ore on the belt generates dust, polluting the surrounding air. Therefore, there is an urgent need to develop a small hopper discharge device that effectively reduces the impact force of the material on the belt, significantly lowers the risk of belt damage, and collects and treats the dust generated during material descent, thus reducing dust pollution. This device would overcome the shortcomings of current applications and meet current needs. Utility Model Content

[0003] The purpose of this utility model is to provide a small weighing hopper feeding device for ore bins to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A small hopper feeding device for ore bins includes a small hopper, a buffer feeding channel, a dust cover, a buffer mechanism, and a dust removal mechanism. The small hopper has legs fixed to its side for support on the ground. A buffer feeding channel is fixed to the lower side of the small hopper and is inclined. A dust cover is fixed to the outer side of the buffer feeding channel. Two buffer mechanisms are rotatably connected to the bottom of the buffer feeding channel. Each buffer mechanism includes a rotating shaft, a baffle, and a spring. The rotating shaft is rotatably connected to the bottom of the buffer feeding channel and fixedly connected to the baffle. The spring provides elastic support to the baffle. Multiple springs are present, with one end fixed to the baffle and the other end fixed to the inner wall of the dust cover. The dust removal mechanism is connected to the dust cover.

[0006] Preferably, the angle between the buffer feeding channel and the horizontal plane is 45°.

[0007] Preferably, the dust removal mechanism includes a negative pressure fan, a suction pipe, an output pipe, and a bag filter. Both the negative pressure fan and the bag filter are installed on the ground. The air inlet of the negative pressure fan is connected to a suction pipe inserted into a dust cover, and the air outlet of the negative pressure fan is connected to an output pipe. The output pipe is connected to the bag filter.

[0008] Preferably, the upper half of the small weighing container is trumpet-shaped.

[0009] Preferably, the small weighing hopper, buffer feeding channel, rotating shaft, and baffle are all made of high manganese steel.

[0010] The beneficial effects of this utility model are as follows: In use, the material enters from the top of the small weighing hopper and then enters the buffer feeding channel, increasing the material's descent time and reducing the final impact on the conveyor belt. When the material slides to the bottom of the buffer feeding channel, it impacts the baffle plate before falling onto the conveyor belt. The baffle plate swings around its shaft due to the impact force, while a spring cushions the impact, further reducing the material's kinetic energy. This significantly reduces the impact force of the material falling onto the conveyor belt, improving its protective performance. Furthermore, the dust cover prevents dust from splashing up after the material falls, and a negative pressure fan draws air to transport the dust to a bag filter, where it is filtered out, thus reducing dust pollution. In summary, this utility model effectively reduces the impact force of material on the conveyor belt, greatly reducing the risk of belt scratches, and collects and treats the dust generated during material descent, reducing dust pollution.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0016] Specific implementation examples are given below.

[0017] See Figures 1-2In this embodiment of the utility model, a small weighing hopper feeding device includes a small weighing hopper 1, a buffer feeding channel 2, a dust cover 3, a buffer mechanism 4, and a dust removal mechanism 5. The small weighing hopper 1 is positioned above the blast furnace charging conveyor belt. Support legs 101 supporting the ground are fixed to the side of the small weighing hopper 1. The upper half of the small weighing hopper 1 is funnel-shaped to facilitate the entry of materials (coke and ore). A buffer feeding channel 2 is fixed to the lower side of the small weighing hopper 1. The buffer feeding channel 2 is inclined, with an angle of 45° between the buffer feeding channel 2 and the horizontal plane. The buffer feeding channel 2 reduces the impact force when the material falls. A dust cover 3 is fixed to the outer side of the buffer feeding channel 2 to cover the dust splashed up after the material falls. Two buffer mechanisms 4 are rotatably connected to the bottom of the buffer feeding channel 2. Each buffer mechanism 4 includes a rotating shaft 401 and a baffle 40. 2. A spring 403 is used to elastically support the baffle 402. Multiple springs 403 are used, with one end fixed to the baffle 402 and the other end fixed to the inner wall of the dust cover 3. The dust removal mechanism 5 is connected to the dust cover 3 and includes a negative pressure fan 50. 1. Suction pipe 502, output pipe 503 and bag filter 504. The negative pressure fan 501 and the bag filter 504 are both installed on the ground. The negative pressure fan 501 and the bag filter 504 are equipped with their own switch buttons. The air inlet end of the negative pressure fan 501 is connected to the suction pipe 502 inserted into the dust cover 3. The air outlet end of the negative pressure fan 501 is connected to the output pipe 503. The output pipe 503 is connected to the bag filter 504.

[0018] The small weighing hopper 1, the buffer feeding channel 2, the rotating shaft 401, and the baffle 402 are all made of high manganese steel, which gives them good impact and wear resistance.

[0019] Working principle: In use, the material enters from the top of the small weighing hopper 1 and then enters the buffer feeding channel 2, increasing the time for the material to slide down and reducing the final impact on the conveyor belt. When the material slides to the bottom of the buffer feeding channel 2, it will impact the baffle 402 and then fall onto the conveyor belt. The baffle 402 swings around the rotating shaft 401 due to the impact force, while the spring 403 buffers the impact force, further reducing the kinetic energy of the material. This greatly reduces the impact force of the material falling onto the conveyor belt and improves the protection performance of the conveyor belt. In addition, the dust cover 3 covers the dust splashed after the material falls, and the negative pressure fan 501 draws airflow to transport the dust to the bag filter 504, where the dust is filtered out, thereby reducing dust pollution.

[0020] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
