Description

Technical Field

[0001] The utility model belongs to the technical field of protective slag, and in particular relates to a raw material feeding mechanism for protective slag production. Background Art

[0002] Mold slag is a melting auxiliary material specially used in the steel smelting process. It plays a key role in improving the quality and production efficiency of steel products. At present, mold slag needs to be loaded during the production process, so a special raw material loading mechanism for mold slag production is needed.

[0003] Existing raw material feeding mechanisms for protective slag production usually use various feeders for feeding operations, such as screw feeders and other equipment. The screw feeders rely on the rotation of the spiral feed frame to transport the raw materials during operation. Although such devices can meet basic feeding needs, when the raw materials are damp, they are prone to agglomeration during the spiral conveying process, which not only hinders the flow of materials, but also affects the subsequent processing of the protective slag raw materials. Utility Model Content

[0004] In view of this, the utility model provides a raw material feeding mechanism for protective slag production, which can effectively break up the agglomerated protective slag raw materials through a breaking rack, promote the flow of the protective slag raw materials, and prevent the protective slag raw materials from getting damp and agglomerated, affecting subsequent operations.

[0005] In order to solve the above technical problems, the utility model provides a raw material feeding mechanism for protective slag production, including a spiral feeder and a discharge pipe arranged at the discharge port of the spiral feeder. The discharge pipe is rotatably connected with symmetrically distributed break-up frames, and the break-up frames are provided with a gear at one end away from the feed port of the spiral feeder. The two gears are meshed and connected to each other. The spiral feeder is also provided with a dispersion mechanism, which can effectively break up the agglomerated protective slag raw materials, promote the flow of the protective slag raw materials, and prevent the protective slag raw materials from getting damp and agglomerating and affecting subsequent operations.

[0006] A pulley 1 is provided at one end of a debonding frame near gear 1, and a pulley 2 is provided at one end of a spiral feeding frame arranged in the spiral feeder near gear 1. The pulley 2 is connected to the pulley 1 through a belt transmission, which plays a role of rapid transmission.

[0007] The dispersion mechanism includes a rotating plate rotatably connected to one end of the screw feeder near the discharge pipe, a dispersion rack rotatably connected to the edge of the rotating plate, and rotating holes corresponding to the dispersion racks are provided at the edge of the spiral feed rack. The end of the spiral feed rack passes through the axis of the rotating plate and extends to the outside, thereby dispersing the protective slag raw material located in the screw feeder 100.

[0008] The dispersion mechanism also includes gear 2 arranged on the dispersion frame near the end of pulley 2, and the spiral feeder is provided with a bevel gear ring on the end near pulley 2. Gear 2 is meshed with the bevel gear ring to play a role of rapid transmission.

[0009] The scattering teeth on the two scattering frames are staggered with each other, which improves the scattering effect.

[0010] A protective cover is provided between the spiral feeder and the discharge pipe on the side close to gear one. The bevel gear ring, gear two, gear one, pulley one and pulley two are all located in the protective cover to prevent foreign matter from entering and personal injury.

[0011] It also includes a negative pressure dust suction component, which is used to extract the dust generated when the protective slag is broken up. The negative pressure dust suction component includes a negative pressure dust suction box arranged on one side of the discharge pipe close to the gear. The dust suction hole arranged on the negative pressure dust suction box is provided with a connecting pipe to maintain the cleanliness of the working environment.

[0012] The beneficial effects of the above technical solution of the utility model are as follows:

[0013] 1. First, regulate the operation of the motor installed on the spiral feeder. The rotation of the motor output shaft drives the spiral feed frame to rotate synchronously. At this time, feed the protective slag raw material into the feed port of the spiral feeder. Under the action of the rotating spiral feed frame, the protective slag raw material is pushed to move to the discharge pipe. The spiral feed frame drives pulley 2 to rotate synchronously during the rotation process. While rotating, pulley 2 drives pulley 1 and its breaking frame and gear 1 to rotate synchronously through the belt. When the gear 1 rotates, it drives another breaking frame through another gear 1 meshing with it to rotate in the same opposite amplitude at the same time. When the protective slag raw material is discharged through the discharge pipe, it can effectively break up the agglomerated protective slag raw material, promote the flow of protective slag raw material, and prevent the protective slag raw material from getting damp and agglomerating, affecting subsequent operations.

[0014] 2. During this process, the rotating plate rotates synchronously with the spiral feed rack. When the rotating plate rotates, it drives the dispersion rack and gear 2 to rotate synchronously. When gear 2 rotates, it cooperates with the bevel gear ring, so that the dispersion rack rotates, which can further promote the dispersion of the protective slag raw materials.

[0015] 3. During the breaking up of the protective slag raw materials, the connecting pipe is connected to the external negative pressure vacuum cleaner. The generated dust is continuously extracted through the connecting pipe by the negative pressure dust collector located at the discharge pipe to maintain the cleanliness of the working environment.

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solutions and advantages of the embodiment of the present invention clearer, the following will be combined with the appended drawings of the embodiment of the present invention. Figure 1-4 , clearly and completely describing the technical solutions of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field fall within the scope of protection of the present invention.

[0022] This embodiment provides a raw material feeding mechanism for mold slag production, such as Figure 1-4 As shown: it includes a screw feeder 100 and a discharge pipe 101 arranged at the discharge port of the screw feeder 100. The screw feeder 100 is composed of a motor near the feed port end and a spiral feed frame inside the body, and the motor output shaft is fixedly connected to the end of the spiral feed frame. The discharge pipe 101 is rotatably connected with a symmetrically distributed disassembly frame 102. The disassembly frame 102 is provided with a gear 103 at one end away from the feed port of the screw feeder 100. The two gears 103 are meshed and connected to each other. The screw feeder 100 is also provided with a dispersion mechanism.

[0023] The operation of the motor installed on the screw feeder 100 is regulated, and the rotation of the motor output shaft drives the spiral feed frame to rotate synchronously. At this time, the protective slag raw material is fed into the feed port of the screw feeder 100. Under the action of the rotating spiral feed frame, the protective slag raw material is pushed to move to the discharge pipe 101, and then the slag breakup frame 102 and gear 103 are driven to rotate synchronously. When the gear 103 rotates, it drives another slag breakup frame 102 to rotate in the opposite direction with the same amplitude through another gear 103 meshing with it. When the protective slag raw material is discharged through the discharge pipe 101, the agglomerated protective slag raw material can be effectively broken up, the flow of the protective slag raw material is promoted, and the protective slag raw material is prevented from being damp and agglomerated, affecting subsequent operations.

[0024] like Figure 2-4 As shown, a debonding frame 102 is provided with a pulley 104 at one end close to gear 103, and a spiral feeding frame arranged in the spiral feeder 100 is provided with a pulley 2 105 at one end close to gear 103, and the pulley 2 105 is connected to the pulley 1 104 through a belt transmission.

[0025] The spiral feed frame drives the pulley 2 105 to rotate synchronously during the rotation process. The pulley 2 105 drives the pulley 1 104 and the breaking frame 102 and the gear 1 103 to rotate synchronously through the belt, thereby playing a role of rapid transmission.

[0026] like Figure 2-4 As shown, the dispersion mechanism includes a rotating plate 300 rotatably connected to one end of the spiral feeder 100 near the discharge pipe 101, and a dispersion rack 301 is rotatably connected to the edge of the rotating plate 300. The edge of the spiral feed rack is provided with rotating holes corresponding to the dispersion rack 301 one by one, and the end of the spiral feed rack passes through the axis of the rotating plate 300 and extends to the outside.

[0027] The rotating plate 300 rotates synchronously with the spiral feed frame. When the rotating plate 300 rotates, it drives the dispersion frame 301 to rotate synchronously, thereby dispersing the protective slag raw materials located in the spiral feeder 100.

[0028] like Figure 2-4 As shown, the dispersion mechanism also includes a gear 2 302 arranged on the dispersion frame 301 near the end of the pulley 2 105, and a bevel gear ring 303 is provided on the end of the spiral feeder 100 near the pulley 2 105, and the gear 2 302 is meshed with the bevel gear ring 303.

[0029] When the second gear 302 rotates, it cooperates with the bevel gear ring 303, so that the dispersion rack 301 rotates, playing the role of rapid transmission.

[0030] like Figure 2-4 As shown, the scattering teeth on the two scattering frames 102 are staggered with each other to improve the scattering effect.

[0031] like Figure 1 As shown, a protective cover 400 is provided between the spiral feeder 100 and the discharge pipe 101 on the side close to the gear 1 103. The bevel gear ring 303, gear 2 302, gear 1 103, pulley 1 104 and pulley 2 105 are all located in the protective cover 400. The setting of the protective cover 400 ensures safe operation and prevents foreign matter intrusion and personal injury.

[0032] like Figure 1-4As shown, it also includes a negative pressure dust suction component, which is used to extract the dust generated when the protective slag is broken up. The negative pressure dust suction component includes a negative pressure dust suction box 200 arranged on the side of the discharge pipe 101 close to the gear 103, and a connecting pipe 201 is provided in the dust suction hole set on the negative pressure dust suction box 200.

[0033] During the process of breaking up the protective slag raw materials, the connecting pipe 201 is connected to an external negative pressure vacuum cleaner, and the generated dust is continuously extracted through the connecting pipe 201 by the negative pressure dust collector box 200 located at the discharge pipe 101 to maintain the cleanliness of the working environment.

[0034] The working principle of a raw material feeding mechanism for protective slag production provided by the present invention is as follows: first, the operation of the motor provided on the spiral feeder 100 is regulated, and the rotation of the motor output shaft drives the spiral feed frame to rotate synchronously. At this time, the protective slag raw material is fed into the feed port of the spiral feeder 100, and the rotating spiral feed frame pushes the protective slag raw material to move to the discharge pipe 101. The spiral feed frame drives pulley 2 105 to rotate synchronously during the rotation process. While the pulley 2 105 rotates, it drives pulley 1 104 and the disintegration frame 102 and gear 1 103 in which it is located to rotate synchronously. When the gear 103 rotates, it drives another disintegration frame 102 to rotate in the same opposite amplitude at the same time through another gear 103 meshing with it. When the protective slag raw material passes through the discharge pipe When the channel 101 is discharged, the agglomerated protective slag raw materials can be effectively broken up, the protective slag raw materials can be promoted to flow, and the protective slag raw materials can be prevented from being damp and agglomerated and affecting subsequent operations. During this process, the rotating plate 300 rotates synchronously with the spiral feed rack. When the rotating plate 300 rotates, it drives the dispersion rack 301 and gear 2 302 to rotate synchronously. When gear 2 302 rotates, it cooperates with the bevel gear ring 303, so that the dispersion rack 301 rotates, which can further promote the dispersion of the protective slag raw materials. The setting of the protective cover 400 ensures safe operation and avoids foreign matter intrusion and personal injury. During the process of breaking up the protective slag raw materials, the connecting pipe 201 is connected to the external negative pressure vacuum cleaner, and the generated dust is continuously extracted by the negative pressure dust box 200 located at the discharge pipe 101 through the connecting pipe 201 to maintain the cleanliness of the working environment.

[0035] Furthermore, it should be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0036] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
