Description

Technical Field

[0001] The utility model relates to the technical field of silicon-manganese alloy smelting, in particular to a reducing agent proportioning device for silicon-manganese alloy smelting. Background Art

[0002] Silicon manganese alloy is an alloy composed of manganese, silicon, iron, a small amount of carbon and other elements. It is a ferroalloy with a wide range of uses and a large output. Silicon manganese alloy is a commonly used composite deoxidizer in steelmaking, and a reducing agent in the production of medium and low carbon ferromanganese and the production of metallic manganese by the electric silicon thermal method.

[0003] In the process of smelting existing silicon-manganese alloy, a reducing agent is required. In the process of producing the reducing agent, a variety of raw materials need to be used for proportioning, so a corresponding proportioning device is required. In actual use, the existing proportioning device introduces the raw materials into the device, and then uses a motor to drive the stirring rod to stir and mix the raw materials to adapt the proportion. However, when the raw materials are introduced into the device, a single raw material will be locally accumulated, so in order to fully stir during stirring, the stirring time required is poor, which affects the efficiency of the raw material proportioning and mixing. Therefore, we propose a reducing agent proportioning device for silicon-manganese alloy smelting. Utility Model Content

[0004] The utility model aims to provide a reducing agent proportioning device for smelting silicon-manganese alloy, which solves the problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a reducing agent proportioning device for silicon-manganese alloy smelting, comprising a base, support plates are fixed on both sides of the top of the base, a stirring box is rotatably installed between the two support plates, a first servo motor is fixed on the outer wall of one of the support plates, a transmission shaft of the first servo motor passes through the support plate and is fixedly connected to one end of the stirring box, a stirring motor is fixed on the outer wall of the other support plate, the transmission shaft of the stirring motor passes through the support plate and the end face of the stirring box and is fixedly connected to a rotating shaft, a plurality of evenly distributed stirring rods are fixed on the outer wall of the rotating shaft, a top plate is fixedly connected to the top of the two support plates, a slide rail is fixed to the top of the top plate, and both sides of the outer wall of the slide rail are equipped with an adaptive electric slider, a hopper is fixedly connected to the top of the electric slider through a connecting plate, a material guide pipe is rotatably connected to the tail end of the hopper, a material distribution flat pipe is fixedly connected to the tail end of the material guide pipe, and an electromagnetic valve is matched and installed between the material distribution flat pipe and the material guide pipe.

[0006] By adopting the above technical scheme, the raw materials are placed in two hoppers respectively, and then one of the electric sliders is started to drive the corresponding hopper to move, and the solenoid valve is opened, so that the raw materials can enter the mixing box along the material guide pipe and the material distribution flat tube, and the moving material can form a material layer. After a single hopper reciprocates the material once, another hopper is used to move again to form a second material layer, and then the alternating materials are used to achieve preliminary mixing of the raw materials. At the same time, the stirring motor is started to drive the stirring rod to rotate to achieve stirring and mixing. After the preliminary mixing, the subsequent stirring time is effectively shortened, thereby significantly improving the stirring efficiency and stirring effect.

[0007] As a preferred embodiment of the utility model, a gear ring is fixedly mounted on the upper side of the outer wall of the guide tube, a gear is meshed on the outer wall of the gear ring, and the gear is fixed to the outer end of the transmission shaft of the second servo motor.

[0008] By adopting the above technical solution, after the stirring and mixing is completed, the second servo motor is started to drive the gear to rotate, thereby driving the gear ring to rotate, so that the material guide pipe and the material distribution flat tube are rotated to one side of the mixing box, and then the first servo motor is started to drive the mixing box to rotate, so that the material after the proportioning and mixing is completed can be directly discharged, making it convenient to discharge the material.

[0009] As a preferred embodiment of the present invention, the top of the second servo motor is fixedly connected to the outer wall of the hopper through a connecting block.

[0010] By adopting the above technical solution, the stability of the second servo motor during use can be ensured.

[0011] As a preferred embodiment of the present utility model, the length of the distribution flat tube is smaller than the width of the inner cavity of the mixing box.

[0012] By adopting the above technical solution, it is ensured that materials are prevented from scattering to the outside of the mixing box during distribution.

[0013] As a preferred embodiment of the present utility model, the transmission shaft of the first servo motor and the transmission shaft of the stirring motor are concentrically arranged.

[0014] By adopting the above technical solution, there will be no interference when the first servo motor and the stirring motor work separately.

[0015] As a preferred embodiment of the utility model, rubber blocks are embedded at the four corners of the bottom of the base.

[0016] By adopting the above technical solution and setting the rubber block, the device as a whole can avoid sliding when in use.

[0017] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0018] The technical solution of the present application is a reducing agent proportioning device for smelting silicon-manganese alloy. The raw materials are introduced into the hopper, and then the electric slider drives the hopper to move along the slide rail, so that the two hoppers can alternately spread the materials into the mixing box layer by layer, so as to achieve preliminary mixing during stirring, so that the stirring time can be greatly shortened when the stirring rod is driven by the motor to stir later, thereby effectively improving the efficiency of proportioning and mixing, and at the same time improving the adequacy of stirring and mixing;

[0019] The first servo motor can drive the mixing box to flip, so that the mixed material can be discharged quickly and conveniently. At the same time, when discharging the material, the second servo motor drives the gear to rotate, so that the gear ring rotates, and then the material guide pipe and the material distribution flat pipe rotate to one side, so as to avoid spatial obstacles to the rotation of the mixing box.

The tail end of the hopper 3 is rotatably connected to a material guide pipe 31. The tail end of the material guide pipe 31 is fixedly connected to a material distribution flat pipe 32, and an electromagnetic valve is matched and installed between the material distribution flat pipe 32 and the material guide pipe 31.

[0029] In actual use, the raw materials are placed in the two hoppers 3 respectively, and then one of the electric sliders 22 is started to drive the corresponding hopper 3 to move, and the solenoid valve is opened, so that the raw materials can enter the mixing box 12 along the material guide pipe 31 and the material distribution flat pipe 32, and the moving material distribution can form a material layer.

After the preliminary mixing, the subsequent stirring time is effectively shortened, thereby significantly improving the stirring efficiency and stirring effect;

[0030] Furthermore, rubber blocks are embedded at the four corners of the bottom of the base 1. The arrangement of the rubber blocks prevents the device from sliding when in use.

[0031] Furthermore, the length of the flat pipe 32 for distributing the material is smaller than the width of the inner cavity of the mixing box 12, thereby ensuring that the material is prevented from being scattered outside the mixing box 12 during distributing the material;

[0032] It is worth mentioning that the transmission shaft of the first servo motor 13 and the transmission shaft of the stirring motor are concentrically arranged, so that there is no interference when the first servo motor 13 and the stirring motor work separately;

[0034] After the mixing is completed, the second servo motor 35 is started to drive the gear 34 to rotate, thereby driving the gear ring 33 to rotate, so that the material guide pipe 31 and the material distribution flat pipe 32 rotate to the side of the mixing box 12, and then the first servo motor 13 is started to drive the mixing box 12 to rotate, so that the materials after the proportioning and mixing are directly discharged, so that the material discharge is convenient;

[0035] Furthermore, the top of the second servo motor 35 is fixedly connected to the outer wall of the hopper 3 via a connecting block, thereby ensuring the stability of the second servo motor 35 during use.

[0036] The implementation principle of the reducing agent proportioning device for smelting silicon-manganese alloy of the present application is as follows: in actual use, the raw materials are placed in two hoppers 3 respectively, and then one of the electric sliders 22 is started to drive the corresponding hopper 3 to move, and the solenoid valve is opened, so that the raw materials can enter the mixing box 12 along the material guide pipe 31 and the material distribution flat pipe 32, and the moving material distribution can form a material layer. After the single hopper 3 reciprocates to distribute the material once, the other hopper 3 is used to move again to form a second material layer, and then the alternating distribution is used to achieve preliminary mixing of the raw materials, and at the same time, the stirring motor is started to drive the stirring rod 15 to rotate to achieve stirring and mixing. After the preliminary mixing, the subsequent stirring time is effectively shortened, thereby significantly improving the stirring efficiency and stirring effect. After the stirring and mixing is completed, the second servo motor 35 is started to drive the gear 34 to rotate, thereby driving the gear ring 33 to rotate, so that the material guide pipe 31 and the material distribution flat pipe 32 rotate to one side of the mixing box 12, and then the first servo motor 13 is started to drive the mixing box 12 to rotate, so that the material after the proportioning and mixing is completed can be directly discharged, so that the material is convenient to discharge.
