Description

Technical Field

[0001] This utility model relates to the field of blast furnace technology, and in particular to a low-cost blast furnace ore structure proportioning device. Background Technology

[0002] A blast furnace uses steel plates as its outer shell, lined with refractory bricks. The blast furnace body is divided into five parts from top to bottom: the throat, the body, the waist, the belly, and the hearth.

[0003] When a blast furnace is in use, it is necessary to feed materials. When the ore to be fed into the furnace is proportioned, it is done manually. It is inconvenient to weigh the weight of each material. At the same time, manual proportioning is time-consuming, labor-intensive and inefficient.

[0004] Therefore, there is an urgent need for improved technologies to solve the above problems. Utility Model Content

[0005] 1. Technical Solution

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a low-cost blast furnace ore proportioning device, comprising,

[0008] The holding assembly includes a holding box, a holding slot formed on the upper surface of the holding box, and brackets fixed to both sides of the holding box;

[0009] The proportioning component is positioned above the container component;

[0010] The proportioning component includes a proportioning box fixed to one side of the support and through slots opened on both sides of the upper surface of the proportioning box;

[0011] as well as;

[0012] Weighing component, movably connected to the lower surface of proportioning component;

[0013] The weighing assembly includes a movable plate movably connected to both sides of the lower surface of the mixing tank, a fixed plate fixed to one side of the movable plate, and a weighing device installed on both sides of the upper surface of the fixed plate.

[0014] Furthermore, four pillars arranged in a rectangular array are fixed to the lower surface of the container;

[0015] Specifically, the support pillars can support the container, making the overall device stable.

[0016] Furthermore, a control switch box is fixed to the front end of the container, and a display screen and buttons are sequentially fitted and installed on the front end of the control switch box from top to bottom;

[0017] Specifically, the control switch box can control the start and stop of the motor and weighing device.

[0018] Furthermore, long slots are respectively opened on both sides of the lower surface of the mixing box, and connecting blocks are inserted into the long slots. A threaded hole is opened at the front end of the connecting block. Round holes are opened on both sides of the front end of the mixing box. Motors are fixed on both sides of the front end of the mixing box. The rear end of the drive shaft of the motor extends into the round hole. A threaded rod is fixed at the rear end of the drive shaft of the motor. The rear end of the threaded rod passes through the threaded hole and is threadedly connected. A movable plate is fixed on the lower surface of the connecting block.

[0019] Specifically, the motor has a drive shaft that fixes the threaded rod, providing power for the rotation of the threaded rod, so that the connecting block and the moving plate can be moved as needed, facilitating the unloading of the weighed material.

[0020] Furthermore, the width of the long slots opened on both sides of the lower surface of the mixing box matches the width of the connecting block;

[0021] Specifically, the width of the long groove matches the width of the connecting block. The long groove can limit the connecting block to prevent the threaded rod from rotating. The connecting block rotates with the groove, making it easy for the connecting block to move.

[0022] Furthermore, the size of the weighing devices installed on both sides of the upper surface of the fixed plate matches the size of the through slots opened on both sides of the upper surface of the mixing box;

[0023] Specifically, the size of the weighing device is matched with the size of the through-channel, which facilitates the weighing of materials placed in the through-channel.

[0024] 2. Beneficial effects

[0025] Compared with existing technologies, the advantages of this utility model are:

[0026] This utility model adds a proportioning component to the upper end of the holding component. When it is necessary to accurately proportion the ore fed into the blast furnace, the two materials are placed into the through groove for weighing. Then the motor is started, which causes the threaded rod to rotate, the connecting block and the weighing device to move, so that the through groove opens and the material enters the holding box.

[0027] At the same time, a weighing device is added. The weighing device can seal the through groove. After the material is put into the through groove, the material falls on the upper surface of the weighing device. The weighing device can accurately weigh the material, which is convenient for accurate proportioning.

[0028] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
