Description

A feeding device for a reduction furnace Technical Field

[0001] This utility model relates to the field of metal smelting technology, specifically to a feeding device for a reduction furnace. Background Technology

[0002] A reduction furnace is a piece of equipment used in metal smelting. It extracts and purifies metals by reducing ores or waste at high temperatures. Currently, existing feeding devices require crushed metal ores to be fed into the reduction furnace. The raw materials contain metal ores with larger particles, which tend to accumulate on the feeding hopper, affecting the efficiency of raw material transportation. At the same time, the oxidation and reduction time of larger particles is longer, which reduces the production efficiency of the reduction furnace. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this utility model provides a feeding device for a reduction furnace, which solves the problem that existing feeding devices require crushed metal ore to be fed into the reduction furnace. However, the raw materials contain large-particle metal ore, which tends to accumulate on the feeding hopper, affecting the efficiency of raw material transportation. At the same time, the oxidation and reduction time of large-particle raw materials is longer, thus reducing the production efficiency of the reduction furnace.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a feeding device for a reduction furnace, comprising a reduction furnace body, a storage tank on the reduction furnace body, a first support block and a second support block on the storage tank, a support seat on the upper wall of the second support block, a motor on the support seat, a cam on the drive end of the motor, a first connecting rod rotatably mounted on the cam, a second connecting rod rotatably mounted on the first connecting rod, the second connecting rod movably mounted on the first support block, a support frame on the second connecting rod, an arc-shaped screen on the support frame, a pair of discharge ports on the storage tank, and a pair of collection boxes movably mounted on the storage tank.

[0005] Preferably, the collection box is provided with a pair of L-shaped fixing blocks, the storage tank is provided with two pairs of first fixing slots and two pairs of second fixing slots, the collection box is inserted into the first fixing slot through the L-shaped fixing blocks, and the longitudinal end of the L-shaped fixing blocks is movably disposed in the second fixing slot.

[0006] Preferably, the storage tank is provided with a feeding hopper, which is located at the feed inlet of the reduction furnace body, and a pair of conical support blocks are provided on the second connecting rod, which are movably disposed inside the feeding hopper.

[0007] Preferably, an arc-shaped dispersion block is provided on the lower wall surface of the second connecting rod.

[0008] Preferably, a support frame is provided between the reduction furnace body and the storage tank.

[0009] Beneficial effects

[0010] The feeding device for a reduction furnace provided by this utility model has the following beneficial effects:

[0011] This design uses a drive motor to rotate a cam, which in turn moves the first connecting rod, causing the second connecting rod to reciprocate up and down. This, in turn, moves the support frame up and down, causing the arc-shaped screen to reciprocate up and down. When the second connecting rod reaches its highest point, the arc-shaped screen moves to the discharge port, facilitating the discharge of larger metal ore particles from the storage tank into the collection box. This prevents larger metal ore particles from accumulating on the feeding hopper and affecting the efficiency of raw material transportation, thereby improving the production efficiency of the reduction furnace. It also prevents the oxidation-reduction time of larger particles from being too long, which could lead to different reaction times in the furnace.

[0012] The collection box in this design is installed in the first fixed slot by inserting an L-shaped fixing block. When the collection box is moved downward, the longitudinal end of the L-shaped fixing block is inserted into the second fixed slot to fix the collection box. The collection box adopts a detachable installation method, which makes it easy for workers to clean the metal ore raw materials inside the collection box. At the same time, the insertion installation method can improve the loading and unloading speed of the collection box, thereby improving the working efficiency of the feeding device.

[0013] This design drives the second connecting rod to move up and down, causing the conical support block to move up and down at the feeding hopper. This clears the feeding hopper and prevents metal raw materials from accumulating in it, which would reduce the material conveying speed and thus improve the working efficiency of the feeding device.

[0014] The arc-shaped dispersion block of this design allows the metal ore raw material falling on it to disperse around and fall into the reduction furnace, avoiding the accumulation of metal ore raw material in the middle of the reduction furnace and reducing the contact area of ​​the metal ore raw material, thereby improving the working efficiency of the reduction furnace.

[0024] The second connecting rod 10 is movably mounted on the first support block 11, and the first support block 11 is used to control the moving direction of the second connecting rod 10.

[0025] The arc-shaped screen 12 can prevent large metal ore particles from accumulating in the middle of the screen and affecting the transportation efficiency of the feeding device.

[0026] The drive motor 18 rotates, causing the cam 7 to rotate, controlling the first connecting rod 8 to move, which in turn drives the second connecting rod 10 to move up and down reciprocatingly, controlling the support frame 13 to move up and down reciprocatingly, thereby causing the arc screen 12 to move up and down reciprocatingly. When the second connecting rod 10 moves to the highest point, the arc screen 12 moves to the discharge port 14, which facilitates the discharge of larger metal ore raw materials from the storage tank 1 and into the collection box 5. This avoids the situation where larger metal ore raw materials accumulate on the feeding hopper 2, affecting the raw material transportation efficiency, thereby improving the production efficiency of the reduction furnace. At the same time, it can prevent the oxidation and reduction time of larger raw materials from being too long, resulting in different reaction times of raw materials in the furnace.

This avoids the accumulation of larger metal ore particles on the feeding hopper 2, which would affect the raw material transportation efficiency, thereby improving the production efficiency of the reduction furnace. At the same time, it can prevent the oxidation and reduction time of larger raw materials from being too long, resulting in different reaction times of raw materials in the furnace. The collection box 5 is inserted into the first fixed groove 17 by an L-shaped fixing block 6. Moving the collection box 5 downwards makes the L-shaped... The longitudinal end of the fixing block 6 is inserted into the second fixing groove 20 to fix the collection box 5. The collection box 5 adopts a detachable installation method, which makes it easy for workers to clean the metal ore raw materials in the collection box 5. At the same time, the insertion installation method can improve the loading and unloading speed of the collection box 5, thereby improving the working efficiency of the feeding device. The second connecting rod 10 moves up and down, driving the conical support block 15 to move up and down at the feeding hopper 2, which is used to clear the feeding hopper 2 and prevent the metal raw materials from accumulating in the feeding hopper 2, which would cause the raw material conveying speed to decrease, thereby improving the working efficiency of the feeding device. The arc-shaped dispersing block 16 can disperse the metal ore raw materials falling on it to the surrounding area and fall into the reduction furnace, preventing the metal ore raw materials from accumulating in the middle of the reduction furnace and reducing the contact area of ​​the metal ore raw materials, thereby improving the working efficiency of the reduction furnace.
