Description

Technical Field

[0001] This utility model relates to the field of raw material processing technology for brick making machines, specifically a layered screening device for raw materials in brick making machines. Background Technology

[0002] Brick making machines are core equipment in the building materials industry. Using stone powder, fly ash, slag, sand, and other raw materials, they can produce various brick types, including sintered bricks and non-fired bricks. They are divided into sintered brick machines and non-fired brick machines, characterized by wide raw material adaptability and high forming efficiency, and are used in the production of building wall materials. Raw material screening is a crucial step in the brick-making process. Through equipment such as vibrating screens and drum screens, large particles and agglomerated materials are separated from the raw materials, and the main materials such as stone powder, fly ash, and sand with uniform particle size are screened out. This prevents impurities from affecting the forming accuracy, improves the stability of the raw material ratio, and enhances the quality of subsequent pressing and forming.

[0003] Current screening devices typically use a single screening screen for screening raw materials for brick making machines. During the screening process, it is difficult to effectively disperse agglomerated raw materials, and the relative displacement between the raw materials and the screening screen is small, resulting in screening efficiency that fails to meet practical requirements. To address these technical problems, a layered screening device for brick making machine raw materials is provided to solve the aforementioned issues. Utility Model Content

[0004] The purpose of this invention is to provide a brick-making machine raw material layering and screening device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A brick-making machine raw material layering and screening device includes a support frame. Parallel and vertically corresponding primary screening baskets and fine screening baskets are slidably mounted on the support frame. A floating screen plate is vertically slidably mounted inside the primary screening basket, and a fixed screen plate is fixed inside the fine screening basket. The primary screening basket is located above the fine screening basket. A guide slide plate located below the fine screening basket is fixed on the support frame. Side guide blocks that are slidably embedded on the side walls of both the primary and fine screening baskets are fixed. A portal frame fixed to the side guide blocks is mounted on the primary screening basket. A motor I is fixed on the portal frame. The output shaft of the motor I drives a central shaft that passes through the floating screen plate. The central shaft is rotatably mounted on the fixed screen plate. Several horizontally arranged extension arms are fixed on the central shaft. Dispersion components for dispersing brick-making raw materials are mounted on the extension arms.

[0006] As an improvement of this utility model: a turntable is rotatably mounted on the support frame, and an eccentrically set fixed seat is fixed on the top of the turntable. A connecting rod is hinged to the fixed seat, and the end of the connecting rod away from the fixed seat is hinged to the side wall of the primary screening basket.

[0007] As an improvement of this utility model: a motor II is fixed on the support frame, and the output shaft of the motor II is connected to the turntable through a belt pulley mechanism.

[0008] As an improvement of this utility model: the dispersing component includes several vertical sleeves fixed on the extension arm, each vertical sleeve is vertically slidably mounted with a sliding column, a connecting spring is fixed between the sliding column and the top of the vertical sleeve, and a crushing blade is fixed at the lower end of the sliding column.

Detailed Implementation

[0016] The technical solution of this utility model will be further described in detail below with reference to specific embodiments: For the first embodiment, please refer to... Figures 1-8 A brick-making machine raw material layering and screening device includes a support frame 1. A primary screening basket 10 and a secondary screening basket 11 are slidably mounted on the support frame 1, and are parallel and vertically corresponding. A floating screen plate 13 is vertically slidably mounted inside the primary screening basket 10, and a fixed screen plate 14 is fixed inside the secondary screening basket 11. The diameter of the screen holes on the floating screen plate 13 is larger than the diameter of the screen holes on the secondary screening basket 11. The primary screening basket 10 is located above the secondary screening basket 11. A guide slide plate 4 located below the secondary screening basket 11 is fixed on the support frame 1. The primary screening basket 10 and the secondary screening basket 11... The side walls of the basket 11 are all fixed with side guide blocks 15 that are slidably embedded in the support frame 1. The primary screening basket 10 is equipped with a portal frame 2 that is fixed with the side guide blocks 15. The portal frame 2 is fixed with a motor I3. The output shaft of the motor I3 drives and connects to a central shaft 12 that passes through the floating screen 13. The central shaft 12 is rotatably mounted on the fixed screen 14. Several horizontally arranged extension arms 25 are fixed on the central shaft 12. The extension arms 25 are equipped with dispersion components for dispersing brick-making raw materials.

[0017] When screening raw materials for brick making using this screening device, the raw materials are put into the primary screening basket 10, and the floating screen plate 13 of the primary screening basket 10 performs the initial screening. The raw materials that pass through the floating screen plate 13 fall into the fine screening basket 11 and undergo secondary screening by the fixed screen plate 14. Finally, the brick making raw materials that meet the requirements fall onto the guide slide plate 4 for collection and processing.

[0018] A turntable 5 is rotatably mounted on the support frame 1. An eccentrically positioned fixed seat 7 is fixed to the top of the turntable 5. A connecting rod 6 is hinged to the fixed seat 7, with the end of the connecting rod 6 away from the fixed seat 7 hinged to the side wall of the primary screening basket 10. A motor II8 is fixed on the support frame 1, and the output shaft of the motor II8 is connected to the turntable 5 via a pulley mechanism 9.

[0019] When motor II8 is started, the output shaft of motor II8 rotates through the pulley mechanism 9 and the turntable 5. The turntable 5 drives the fixed seat 7 to rotate. The fixed seat 7 pulls the primary screening basket 10 through the connecting rod 6. At this time, under the guidance of the side guide block 15, the primary screening basket 10 and the fine screening basket 11 reciprocate relative to the support frame 1, so that the brick-making raw materials inside the primary screening basket 10 and the fine screening basket 11 are fully shaken. The brick-making raw materials have sufficient relative displacement with the floating screen plate 13 and the fixed screen plate 14, which promotes the full screening of the brick-making raw materials.

[0020] In addition, the dispersion component of this device includes several vertical sleeves 17 fixed on the extension arm 25. Each vertical sleeve 17 is vertically slidably mounted with a sliding column 27. A connecting spring 26 is fixed between the sliding column 27 and the top of the vertical sleeve 17. A crushing blade 18 is fixed at the lower end of the sliding column 27.

[0021] The central shaft 12 rotates and drives multiple extension arms 25 to rotate. During the rotation of the extension arms 25, the vertical sleeve 17, sliding column 27 and crushing blade 18 installed on them are driven to rotate respectively. During the rotation of the crushing blade 18, the brick-making raw materials on the floating screen plate 13 are broken down and refined to prevent the brick-making raw materials from clumping, improve the looseness of the raw materials, and effectively improve the screening efficiency of the raw materials.

[0022] Second embodiment, please refer to Figures 1-8 In addition to the first embodiment, several L-shaped connecting plates 21 are fixed on the floating screen plate 13. The L-shaped connecting plates 21 are vertically slidably installed on the primary screening basket 10. A vertical spring 23 is fixed between the primary screening basket 10 and the L-shaped connecting plate 21.

[0023] A rotating ring plate 19 is fixed on the extension arm 25 and sleeved on the primary screening basket 10. Several lower protrusions 20 are evenly distributed in the circumferential direction at the bottom of the rotating ring plate 19. An upper protrusion 22 corresponding to the rotation of the lower protrusions 20 is fixed on the L-shaped connecting plate 21. A rotating locking block 24 is fixed on the rotating ring plate 19 and is slidably embedded in the side wall of the primary screening basket 10 along the circumferential direction.

[0024] With the above configuration, when the central shaft 12 rotates, the central shaft 12 drives the rotating ring plate 19 to rotate through the extension arm 25. The rotating block 24 on the rotating ring plate 19 slides circumferentially relative to the primary screening basket 10, which plays a guiding role in the rotation process of the rotating ring plate 19. At this time, the lower protrusion 20 rotates with the rotating ring plate 19, and multiple lower protrusions 20 slide and push against each other one by one. Under the elastic connection of the vertical spring 23, the L-shaped connecting plate 21 drives the floating screen plate 13 to vibrate relative to the primary screening basket 10 in the vertical direction. The raw material on the floating screen plate 13 vibrates, and the screening efficiency of the brick-making raw material is greatly improved.

[0025] In addition, several comb-toothed baffles 16 are fixed on the central shaft 12 and contact the upper surface of the fixed screen plate 14. When the central shaft 12 rotates, the central shaft 12 drives the multiple comb-toothed baffles 16 to rotate. The comb-toothed baffles 16 move and disperse the brick-making raw materials on the fixed screen plate 14, further improving the screening efficiency of the brick-making raw materials.

[0026] In summary, this utility model, through the reciprocating motion of the primary screening basket 10 and the fine screening basket 11 relative to the support frame 1, and the rotation of the dispersing component on the extension arm 25 to disperse and refine the brick-making raw materials in the floating screen plate 13, simultaneously drives the rotating ring plate 19 to rotate, thereby rotating the lower protrusion 20. Multiple lower protrusions 20 abut against the upper protrusion 22, enabling the floating screen plate 13 to vibrate vertically relative to the primary screening basket 10, effectively promoting the full screening of the brick-making raw materials in the primary screening basket 10. The primary screening basket 10 and the fine screening basket 11 perform two screenings on the brick-making raw materials, greatly improving the screening efficiency of the brick-making raw materials.
