Description

Technical Field

[0001] This utility model belongs to the field of metallurgical auxiliary material processing technology, specifically relating to a vibration grading and screening device for metallurgical auxiliary materials. Background Technology

[0002] Metallurgical auxiliary raw materials are a general term for raw materials used as fluxes and refractory materials in the metallurgical industry. They mainly include magnesite, refractory clay, high-alumina clay, dolomite, silica, high-alumina mineral raw materials, and molding sand. These auxiliary materials are added during the metal smelting process to enhance the various mechanical properties of the metal. Since these auxiliary materials contain materials of different particle sizes, they need to be screened using filtration devices to separate the particles. Once the required particle size is achieved, the material can proceed to the next processing step.

[0003] Some screens use different particle sizes to screen materials, and can also vibrate to peel off agglomerated materials. If the agglomerated material is very dense, the excitation force needs to be adjusted. However, a large force can easily affect the material and is not conducive to screening. Utility Model Content

[0004] This utility model provides a vibratory grading and screening device for metallurgical auxiliary materials, which is convenient for handling agglomerated materials and for carrying out screening work during the grading and screening process.

[0005] This utility model provides the following technical solution: a vibratory grading and screening device for metallurgical auxiliary materials, comprising a screening machine body, wherein a plurality of screening chambers are provided in the screening machine body, and a material control and stripping component is provided in the screening chamber. The material control and stripping component includes a V-shaped vibrating plate and a plurality of dividing extension columns. The V-shaped vibrating plate has a vibrating surface and a filter groove for material leakage. The plurality of dividing extension columns are slidably connected to the V-shaped vibrating plate, and the dividing extension columns are opposite to the vibrating surface. Both the dividing extension columns and the vibrating surface act on the agglomerated material for screening.

[0006] The screening chamber is fixedly connected to a first screening screen and a second screening screen, with the first screening screen located above the second screening screen.

[0007] The filter media tank is opposite to the first screening screen and the second screening screen, with the first screening screen located below the filter media tank.

[0008] The vibration surface is adjusted by a vibration motor to control the excitation force of the vibrating material, and both sides of the filter media tank have vibration surfaces.

[0009] The screening machine body is fixedly connected to a fixed plate, and the dividing extension column is threadedly connected to the fixed plate.

[0010] The outer side of the dividing column is fitted with an elastic sealing gasket, which is fixedly connected to the V-shaped vibrating plate.

[0011] The screening machine body is equipped with a door and a feed hopper, and the outer wall of the dividing column is threaded with an adjusting cap for limiting the position.

[0012] The beneficial effects of this utility model are:

[0013] The material control and stripping assembly includes a V-shaped vibrating plate and several dividing extension columns. When the material enters the screening machine, the vibrating surfaces on both sides of the filter trough control the material to vibrate, concentrating it around the outer edge of the filter trough. Simultaneously, influenced by the dividing extension columns, the material can contact the outer surface of the columns, further separating it. The separated material then passes through the filter trough and is screened using the first and second screening screens. This facilitates the handling of agglomerated materials during the grading and screening process, and is beneficial for screening operations.

[0014] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0020] Please see Figures 1-4The present invention provides the following technical solution: it includes a screening machine body 1, which has a plurality of screening chambers 14. The screening chambers 14 are provided with a material control and stripping assembly 2. The material control and stripping assembly 2 includes a V-shaped vibrating plate 21 and a plurality of dividing extension columns 22. The V-shaped vibrating plate 21 has a vibrating surface 211 and a filter groove 212 for material leakage. The plurality of dividing extension columns 22 are slidably connected to the V-shaped vibrating plate 21. The dividing extension columns 22 are opposite to the vibrating surface 211. The dividing extension columns 22 and the vibrating surface 211 both act on the agglomerated material for screening.

[0021] In this embodiment: the material control and stripping assembly 2 includes a V-shaped vibrating plate 21 and several dividing extension columns 22. The V-shaped vibrating plate 21 has a filter groove 212 for material leakage. The several dividing extension columns 22 are slidably connected to the V-shaped vibrating plate 21. The dividing extension columns 22 are opposite to the vibrating surface 211. Both the dividing extension columns 22 and the vibrating surface 211 act on the agglomerated material for screening. When the material enters the screening machine body 1, it is subjected to the action of the vibrating surfaces 211 on both sides of the filter groove 212. The vibrating surfaces 211 are adjusted by a vibrating motor to vibrate the material. The filter groove 212 has vibrating surfaces 211 on both sides, which can control the material to be in a vibrating state, concentrating the material around the outer perimeter of the filter groove 212, while being subjected to the action of the dividing extension columns 22. The material can come into contact with the outer surface of the separating column 22, further separating the material. The separated material passes through the filter tank 212 and is screened by the first screening screen 12 and the second screening screen 13. During the grading and screening process, it is beneficial to handle agglomerated materials and facilitate the screening work. Under the action of the V-shaped shaking vibrating plate 21, the material can be controlled to concentrate inward, which is conducive to the contact between materials. Thus, through the action of vibration, the action of material-to-material contact, and the action of material contact on the outer surface of the separating column 22, the excitation force can be adjusted, so that the material can pass through the filter tank 212 with high efficiency. The screen holes of the first screening screen 12 and the second screening screen 13 are large and small, respectively, from coarse to fine filtration, thereby ensuring the screening effect of metallurgical auxiliary materials.

[0022] A first screening screen 12 and a second screening screen 13 are fixedly connected inside the screening chamber 14. The first screening screen 12 is located above the second screening screen 13. The filter media trough 212 is opposite to the first screening screen 12 and the second screening screen 13, with the first screening screen 12 located below the filter media trough 212. The material can pass through the filter media trough 212 efficiently. The screen holes of the first screening screen 12 and the second screening screen 13 are large and small, respectively, and the material is filtered from coarse to fine, thereby ensuring the screening effect of metallurgical auxiliary materials.

[0023] A fixed plate 23 is fixedly connected inside the screening machine body 1. The dividing extension column 22 is threadedly connected to the fixed plate 23. The screening machine body 1 is provided with a box door and a feed hopper 11. The outer wall of the dividing extension column 22 is threadedly connected with an adjusting cap 24 for limiting the position. The dividing extension column 22 slides on the V-shaped shaking vibrating plate 21. The adjusting cap 24 locks the position of the dividing extension column 22, controlling the dividing extension column 22 at the required operating height.

[0024] An elastic sealing gasket 25 is fitted on the outside of the dividing column 22, and the elastic sealing gasket 25 is fixedly connected to the V-shaped material shaking vibrating plate 21. When the V-shaped material shaking vibrating plate 21 vibrates, the elastic sealing gasket 25 can ensure the sealing between the dividing column 22 and the V-shaped material shaking vibrating plate 21.

[0025] The working principle and usage process of this utility model are as follows: During use, the V-shaped vibrating plate 21 has a filter trough 212 for material leakage. Several dividing extension columns 22 are slidably connected to the V-shaped vibrating plate 21. The dividing extension columns 22 are opposite to the vibrating surface 211. Both the dividing extension columns 22 and the vibrating surface 211 act on the agglomerated material for screening. When the material enters the screening machine body 1, it is subjected to the action of the vibrating surfaces 211 on both sides of the filter trough 212. The vibrating surfaces 211 are adjusted by a vibrating motor to control the material's vibration. The filter trough 212 has vibrating surfaces 211 on both sides, which can control the material to be in a vibrating state, concentrating the material around the outer perimeter of the filter trough 212. Simultaneously, influenced by the dividing extension columns 22, the material can contact the dividing surfaces. The material is further separated by the outer surface of the insert column 22, allowing the separated material to pass through the filter trough 212 and be screened by the first screening screen 12 and the second screening screen 13. This facilitates the handling of agglomerated materials during the grading and screening process. Under the action of the V-shaped vibrating plate 21, the material can be controlled to concentrate inward, which is conducive to the contact between materials. Thus, through the action of vibration, the action of material-to-material contact, and the action of material contact on the outer surface of the insert column 22, the excitation force can be adjusted, allowing the material to pass through the filter trough 212 with high efficiency. The screen holes of the first screening screen 12 and the second screening screen 13 are large and small, respectively, from coarse to fine filtration, thereby ensuring the screening effect of metallurgical auxiliary materials.
