Description

Technical Field

[0001] This utility model relates to the field of intermediate ladle refractory material production technology, specifically to a material screening device for intermediate ladle refractory material production. Background Technology

[0002] The tundish is a refractory container used in short-process steelmaking. It first receives molten steel poured from the ladle, and then distributes it to various crystallizers through the tundish nozzle. Steel, as a crucial basic raw material, plays a vital role in the economic development of countries worldwide. In the production of refractory materials for the tundish, to achieve a scientific particle size distribution and improve the bulk density and strength of the processed product, a screening device is used to sieve the material.

[0003] The existing screening device uses a vibrating motor to drive multiple sets of screens to vibrate in order to screen the refractory materials on their surface. However, it is inconvenient to adjust the screen angle according to the specific characteristics of the refractory materials during use. This results in some materials rolling off the screens at a relatively high speed, affecting the screening effect. Furthermore, direct feeding of materials can easily damage the screen components. Therefore, a material screening device for refractory material production in tundishes is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a material screening device for the production of refractory materials in intermediate ladles, so as to solve the problems mentioned in the background art. In the process of use, the existing screening device is inconvenient to adjust the angle of the screen according to the condition of the refractory material itself, which causes some materials to roll off the screen too fast, affecting the screening effect, and the direct feeding of materials can easily damage the screen components.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a material screening device for the production of refractory materials in intermediate ladles, comprising a vibrating screen body, a support frame on the outer wall of the vibrating screen body, and vibrating motors on both outer walls of the vibrating screen body; multiple sets of rotating blocks on both inner walls of the vibrating screen body, and fixed frames on opposite sides of the rotating blocks; sliders on the outer sides of both ends of the fixed frames, and spiral grooves on the sliders; multiple sets of spiral holes evenly distributed on both outer walls of the vibrating screen body, and first bolts spirally wound on the vibrating screen body and the sliders; an installation frame inserted inside the fixed frame, and a first screen and a second screen respectively on the installation frame; a third bolt inserted through the installation frame and the fixed frame, and a nut spirally wound on the lower end of the third bolt;

[0006] The vibrating screen body has a base plate at one end, and multiple sets of spiral holes and spiral grooves are opened on both sides of the vibrating screen body and the base plate. Multiple sets of second bolts are spirally screwed on the vibrating screen body and the base plate. A rubber pad is provided on the upper surface of the base plate, and a material receiving hopper is provided above the rubber pad. Multiple sets of material distribution rods are provided inside the material receiving hopper, and multiple sets of material distribution plates are evenly provided on one side of the material distribution rods. Through holes and limiting grooves are opened on both sides of the material receiving hopper and the vibrating screen body, and limiting rods are engaged in the through holes and limiting grooves.

[0007] The receiving hopper is provided with a motor box on one side of the vibrating screen body, and a servo motor is provided in the motor box. One end of the output shaft of the servo motor is connected to the rotating shaft through a coupling, and the rotating shaft is connected to the baffle plate on the outer wall through multiple sets of connecting rods.

[0008] Preferably, the fixing frame forms a rotating structure inside the vibrating screen body through a rotating block, and the fixing frame forms a spiral locking structure with the vibrating screen body through multiple sets of first bolts.

[0009] Preferably, the mounting bracket is inserted into the slide groove on the fixed bracket, and the mounting bracket is connected to the fixed bracket in a spiral locking structure by multiple sets of third bolts and nuts.

[0010] Preferably, the receiving hopper is connected to the vibrating screen body via multiple sets of second bolts, limiting rods, and a bottom plate to form a spiral locking structure.

[0011] Preferably, the baffle plate forms a rotating structure inside the vibrating screen body via a rotating shaft under the action of a servo motor.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: The fixed frame of the material screening device for intermediate ladle refractory material production forms a rotating structure inside the vibrating screen body through a rotating block, and the fixed frame forms a spiral locking structure with the vibrating screen body through multiple sets of first bolts. Thus, the angle of multiple sets of screens can be easily adjusted through the rotatable fixed frame, making it easy to know the residence time and movement speed of the material on the screen according to the material conditions. The receiving hopper of this device forms a spiral locking structure with the vibrating screen body through multiple sets of second bolts, limit rods, and a bottom plate. Thus, the spirally installed receiving hopper assembly prevents the material from falling directly onto the screen and causing damage to the screen. At the same time, the multiple material components inside the receiving hopper effectively ensure that the refractory material is dispersed into the vibrating screen body for screening. The baffle plate of this device forms a rotating structure inside the vibrating screen body through a rotating shaft under the action of a servo motor. Thus, the rotating baffle plate does not affect the screening of refractory materials and can prevent some materials from rolling on the screen at a high speed, which would affect the screening effect.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 This utility model provides a technical solution: a material screening device for the production of intermediate refractory materials, including a vibrating screen body 1, a support frame on the outer wall of the vibrating screen body 1, and vibrating motors on both outer walls of the vibrating screen body 1. Multiple sets of rotating blocks 4 are provided on both inner walls of the vibrating screen body 1, and fixed frames 5 are respectively provided on opposite sides of the rotating blocks 4. Slider blocks are respectively provided on the outer sides of both ends of the fixed frames 5, and spiral grooves are opened on the sliders. Multiple sets of spiral holes are evenly provided on both outer walls of the vibrating screen body 1, and first bolts 6 are spirally screwed on the vibrating screen body 1 and the sliders respectively.

[0020] Furthermore, the fixed frame 5 forms a rotating structure inside the vibrating screen body 1 through the rotating block 4, and the fixed frame 5 forms a spiral locking structure with the vibrating screen body 1 through multiple sets of first bolts 6. Thus, the rotating block 4 and its related components can easily drive the fixed frame 5 to rotate, so as to adjust the angle of the screen according to the size, weight and other conditions of the material to be screened.

[0021] A mounting frame 7 is inserted inside the fixed frame 5, and a first screen 2 and a second screen 3 are respectively provided on the mounting frame 7. A third bolt 17 is inserted on the mounting frame 7 and the fixed frame 5, and a nut is screwed on the lower end of the third bolt 17.

[0022] Furthermore, the mounting bracket 7 is inserted into the groove on the fixed bracket 5, and the mounting bracket 7 forms a spiral locking structure with the fixed bracket 5 through multiple sets of third bolts 17 and nuts, thereby facilitating the normal installation of multiple sets of screen components.

[0023] The vibrating screen body 1 has a base plate 11 at one end. Multiple sets of spiral holes and spiral grooves are opened on both sides of the vibrating screen body 1 and the base plate 11. Multiple sets of second bolts 9 are spirally screwed on the vibrating screen body 1 and the base plate 11. A rubber pad is provided on the upper end face of the base plate 11. A receiving hopper 8 is provided above the rubber pad. Multiple sets of material distribution rods 12 are provided inside the receiving hopper 8. Multiple sets of material distribution plates 13 are evenly provided on one side of the material distribution rods 12. Through holes and limiting grooves are opened on both sides of the receiving hopper 8 and the vibrating screen body 1. Limiting rods 10 are engaged in the through holes and limiting grooves. It should be noted that a feeding conveyor belt is provided on one side of the screening machine. The end of the conveyor belt that discharges material is located at the receiving hopper 8 so that the material can be continuously conveyed into the vibrating screen body 1 through the conveyor belt.

[0024] Furthermore, the receiving hopper 8 forms a spiral locking structure with the vibrating screen body 1 through multiple sets of second bolts 9, limit rods 10, and bottom plate 11. This prevents materials from falling onto the screen and causing impact damage through the inclined receiving hopper 8. At the same time, the receiving hopper 8 and its internal multiple material feeding components effectively prevent material accumulation.

[0025] A motor box is provided on one side of the receiving hopper 8 on the vibrating screen body 1, and a servo motor 14 is provided in the motor box. One end of the output shaft of the servo motor 14 is connected to the rotating shaft 15 through a coupling, and the rotating shaft 15 is connected to the baffle plate 16 on the outer wall through multiple sets of connecting rods. It should be noted that each group of electrical components in this device is equipped with shock absorption and heat dissipation structures during installation to ensure normal operation. High-strength bolt assemblies are used in this device to ensure the connection stability between the components. This utility model is a material screening device for the production of intermediate ladle refractory materials. All components are standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. All electrical components mentioned above in this device refer to power elements, electrical components, and the matching monitoring computer and power supply connected by wires. The specific connection method should refer to the working principle above to complete the electrical connection between each electrical component in sequence. The detailed connection method is a well-known technology in this field.

[0026] Furthermore, under the action of the servo motor 14, the baffle plate 16 forms a rotating structure within the vibrating screen body 1 via the rotating shaft 15, thereby preventing some heavier refractory materials from sliding rapidly off the screen and affecting its screening effect.

[0027] Working Principle: In the material screening device for intermediate ladle refractory material production, firstly, a screen with the corresponding mesh size is selected based on the required intermediate ladle refractory material to be screened. This screen is then installed on the fixed frame 5 using multiple sets of third bolts 17 and nuts. Subsequently, the screen angle can be adjusted according to the size and dimensions of the refractory material to be screened. The fixed frame 5 is rotated by a rotating block 4, and the rotated fixed frame 5 is helically limited by multiple sets of first bolts 6. The rotating fixed frame 5 then adjusts multiple sets of screens to a suitable tilt angle to ensure the residence time and movement speed of the refractory material on the screen surface. After the screen angle is determined, the operator drives the various electrical components on the screening device through the controller, ensuring they operate according to the program. This allows the conveyor belt to uniformly feed the processed refractory material at a suitable speed, and the vibrating screen body 1 is closed. Appropriate amplitude is used to screen refractory materials. During the plasticizing process, the inclined receiving hopper 8 can receive the material, thus preventing it from falling directly onto the screen and causing impact damage. At the same time, the rubber pad can effectively increase the buffering effect of the receiving hopper 8, and the multi-component material assembly on the inner wall of the receiving hopper 8 can effectively ensure the dispersed feeding of refractory materials, thereby ensuring the subsequent screening effect of refractory materials on the inner wall of the vibrating screen body 1. During the screening process, the servo motor 14 can drive the rotating shaft 15 to rotate, so that the angle of the baffle plate 16 can be adjusted through the rotating shaft 15. Thus, without affecting the screening of refractory materials, the baffle plate 16 at a suitable angle can prevent some materials from sliding quickly on the screen and affecting the screening effect of the device, further ensuring the screening accuracy of the device for intermediate ladle refractory materials. This is the usage process of the material screening device for intermediate ladle refractory material production.

[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
