Description

Technical Field

[0001] This utility model relates to the field of silicon-manganese alloy smelting technology, and more specifically, to a reducing agent proportioning device for silicon-manganese alloy smelting. Background Technology

[0002] As an important ferroalloy product, silicon-manganese alloy is mainly smelted by using a carbothermal reduction method in an electric arc furnace to reduce valuable elements from raw materials such as manganese ore and silica. In this process, the precise amount and proportion of carbonaceous reducing agent (mainly coke) are the core factors determining the smooth progress of smelting and the quality of technical and economic indicators.

[0003] For example, the Chinese utility model patent (publication number: CN222239719U) discloses a "reducing agent proportioning device for smelting silicon-manganese alloy". The specification states that: the raw material is introduced into the hopper, and then the electric slider drives the hopper to move along the slide rail. The two hoppers can alternately spread the material into the mixing tank layer by layer, thereby improving the initial mixing during the mixing process. This greatly shortens the mixing time when the motor drives the stirring rod to stir later, thus effectively improving the proportioning and mixing efficiency and the thoroughness of the mixing.

[0004] Regarding the aforementioned technologies, this device has some shortcomings. In actual use, the top of the mixing tank is open when the material is being distributed. The movement of the hopper and the high-speed rotation of the mixing rod easily generate a large amount of dust that spills out. This not only seriously deteriorates the workshop working environment and endangers the health of operators, but also causes serious waste of raw materials and increases production costs. At the same time, dust accumulation on the equipment surface will accelerate the wear of parts and affect the service life and operational stability of the equipment.

[0005] Therefore, we have made improvements to this and proposed a reducing agent proportioning device for smelting silicon-manganese alloys. Utility Model Content

[0013] As a preferred technical solution of this application, the top of the U-shaped sealing cover is fixedly equipped with symmetrically distributed limiting rods, and the top of the connecting frame is provided with sliding holes corresponding to the position and number of the limiting rods. The connecting frame is slidably connected to the limiting rods through the sliding holes.

[0014] As a preferred technical solution of this application, one end of the connecting frame is fixedly installed with symmetrically distributed reinforcing rods between it and the outer surface of the mixing tank.

[0015] As a preferred technical solution of this application, a discharge trough is provided on the other side of the top of the substrate, and a discharge plate is fixedly installed at the other end of the mixing tank, with the discharge plate corresponding to the position of the discharge trough.

[0016] As a preferred technical solution of this application, an extension rod is fixedly installed on one side of the substrate, and a controller is fixedly installed on one end of the extension rod.

[0017] As a preferred technical solution of this application, a sealing gasket is fixedly installed on the outer wall of the U-shaped sealing cover, and an L-shaped opening is provided on the upper surface of the mixing tank, and the mixing tank is adapted to the U-shaped sealing cover.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] In the scheme of this application:

[0020] 1. Through the coordinated use of a base plate, base, support, movable seat, mixing tank, servo motor, U-shaped sealing cover, hopper, feeding assembly, electric telescopic rod, connecting frame, mixing shaft, mixing roller, and hydraulic telescopic rod, the controller drives the electric telescopic rod to lower the U-shaped sealing cover and close it with the mixing tank to form a closed processing chamber. Raw materials smoothly enter through the elastic telescopic connecting pipe and feed pipe of the feeding assembly. The servo motor drives the mixing roller to mix, while the hydraulic telescopic rod pushes the mixing tank to oscillate back and forth, guiding the material to both sides, significantly improving mixing uniformity and efficiency. The closed structure effectively prevents dust spillage, protecting the environment and reducing costs. During discharge, the U-shaped sealing cover moves upward, and the mixing assembly moves out accordingly. The modular design facilitates cleaning and maintenance, improving ease of use.

[0021] 2. By using the discharge chute and discharge plate together, after the raw materials are mixed, the controller drives the electric telescopic rod to move the U-shaped sealing cover upward and separate it from the mixing tank. Then, the hydraulic telescopic rod is controlled to push the mixing tank to the left. The material in the tank slides down through the left opening under the action of gravity and is stably discharged under the guidance of the discharge plate, realizing fast and smooth discharge and effectively improving discharge efficiency and operational stability.

[0022] 3. By using the reinforcing rod and the limiting rod in combination, the limiting rod slides on the connecting frame during the lifting and lowering of the U-shaped sealing cover. The limiting rod guides and limits the U-shaped sealing cover, effectively improving the stability and structural robustness of the U-shaped sealing cover and its internal stirring components. In addition, the reinforcing rod significantly enhances the connection strength between the connecting frame and the mixing tank, making the overall operation of the device more stable and reliable.

[0033] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0034] Example 1

[0035] Please refer to Figures 1-5 A reducing agent proportioning device for smelting silicon-manganese alloy includes a base plate 1, a base 2 fixedly installed at the bottom of the base plate 1, a support 3 fixedly installed at the top of the base plate 1, a movable seat 4 rotatably installed on the support 3 via a rotating shaft, a mixing tank 7 fixedly installed at the top of the movable seat 4, and a connecting frame 15 fixedly installed at one end of the mixing tank 7.

[0036] An electric telescopic rod 13 is fixedly installed on the top of the connecting frame 15. The driving end of the electric telescopic rod 13 passes through the connecting frame 15 and extends to the top of the mixing tank 7. A U-shaped sealing cover 9 is fixedly installed on the driving end of the electric telescopic rod 13. A mixing component is provided inside the U-shaped sealing cover 9.

The driving end of the hydraulic telescopic rod 18 is hinged to the outer surface of the connecting frame 15. A feeding assembly 12 is provided on the top of the connecting frame 15.

[0038] Furthermore, the stirring assembly includes a stirring shaft 16 rotatably mounted inside the U-shaped sealing cover 9, a plurality of stirring rollers 17 fixedly mounted on the outer wall of the stirring shaft 16, a servo motor 8 fixedly mounted on one end of the U-shaped sealing cover 9, the drive end of the servo motor 8 passing through the U-shaped sealing cover 9 and extending into the interior of the U-shaped sealing cover 9, and the drive end of the servo motor 8 being fixedly connected to one end of the stirring shaft 16.

[0039] Furthermore, the feeding assembly 12 includes a hopper 11 fixedly installed on the top of the connecting frame 15.

The top end of the inlet pipe 22 is fixedly connected to the bottom end of the elastic telescopic connecting pipe 24. A one-way valve 23 is provided on the bottom discharge end of the hopper 11. The feeding assembly 12 connects the hopper 11 and the inlet pipe 22 through the elastic telescopic connecting pipe 24. It can automatically expand and contract to compensate when the U-shaped sealing cover 9 is raised or lowered, keeping the material conveying channel always unobstructed. The one-way valve 23 effectively prevents backflow of materials or dust during the mixing process, ensuring the sealing and smoothness of the feeding process.

[0040] Furthermore, a discharge trough 5 is provided on the other side of the top of the substrate 1, and a discharge plate 6 is fixedly installed at the other end of the mixing tank 7, with the discharge plate 6 corresponding to the position of the discharge trough 5. This ensures that the material discharged from the mixing tank 7 is accurately guided into the discharge trough 5 through the discharge plate 6, achieving stable and smooth discharge guidance.

[0041] Furthermore, an extension rod 20 is fixedly installed on one side of the substrate 1, and a controller 19 is fixedly installed at one end of the extension rod 20. This facilitates operation by the operator and improves operational convenience.

[0044] The reducing agent proportioning device for smelting silicon-manganese alloy provided in Example 1 is further optimized. Specifically, the top of the U-shaped sealing cover 9 is fixedly equipped with symmetrically distributed limiting rods 14, and the top of the connecting frame 15 is provided with sliding holes corresponding to the position and number of the limiting rods 14.

[0045] Furthermore, symmetrically distributed reinforcing rods 10 are fixedly installed between one end of the connecting frame 15 and the outer surface of the mixing tank 7. This effectively enhances the connection strength between the connecting frame 15 and the mixing tank 7, improving the overall structural stability and reliability of the device during operation.

[0046] It should be noted that the controller control circuit can be implemented by those skilled in the art through simple programming, and is common knowledge in the field. It is only used and not modified, so the control method and circuit connection will not be described in detail.

[0047] The following is the usage process of the reducing agent proportioning device for silicon-manganese alloy smelting provided by this utility model:

[0048] In operation, the electric telescopic rod 13 is first activated by the controller 19. Its drive end moves the U-shaped sealing cover 9 vertically and simultaneously drives the internal stirring assembly to displace, causing the U-shaped sealing cover 9 to close downwards with the opening of the mixing tank 7, thus forming a closed processing chamber. During this process, the U-shaped sealing cover 9 stretches the elastic telescopic connecting pipe 24 through the feed pipe 22. In the closed state, raw materials are fed into the hopper 11 of the feeding assembly 12. The raw materials are guided into the feed pipe 22 through the elastic telescopic connecting pipe 24 and finally enter the closed processing chamber formed by the mixing tank 7 and the U-shaped sealing cover 9. Simultaneously, the controller 19 controls the servo motor 8 to drive the stirring shaft 16 to rotate, causing the stirring roller 17 to stir and mix the raw materials. The hydraulic telescopic rod 18 reciprocates, swinging left and right through the hinged connecting frame 15, thereby driving the mixing tank 7 to swing the movable seat 4 back and forth on the support 3, guiding the incoming raw materials to both sides, improving the uniformity of raw material distribution, and significantly improving mixing efficiency in conjunction with the stirring assembly. The entire mixing process is completed within a closed processing chamber, effectively preventing dust spillage, protecting the workshop environment, and reducing production costs. During discharge, the U-shaped sealing cover 9 moves upward and separates from the mixing tank 7, and the mixing components move out of the tank accordingly, realizing a modular structure design. This facilitates subsequent cleaning and maintenance of the mixing tank 7 and the mixing components on the U-shaped sealing cover 9, significantly improving the ease of use of the device.

[0049] After the raw materials are mixed, the controller 19 drives the electric telescopic rod 13 to move the U-shaped sealing cover 9 upward, separating it from the mixing tank 7. Then, the drive end of the hydraulic telescopic rod 18 is extended to push the mixing tank 7 to tilt to the left around the hinge point between the movable seat 4 and the support 3. The mixed materials inside the mixing tank 7 slide down along the tilt direction under the action of gravity and are discharged through the left opening of the mixing tank 7. Under the guidance of the discharge plate 6, the materials are stably discharged, thus realizing the fast, smooth and stable discharge process of the device.
