A glass sand dispersing machine

Abstract

This utility model provides a glass sand dispersing machine, including a dispersing box and a conical hopper. The conical hopper is welded to the lower end of the dispersing box, and an intercepting filter screen is horizontally welded inside the conical hopper. A conical sand-proof shell is installed through the center of the intercepting filter screen by bolts. A small motor is built into the conical sand-proof shell, and the movable end of the small motor passes through the conical sand-proof shell and is fixed to the dispersing plate. A drive shaft is installed through the upper end of the dispersing box by bearings, and multiple coarse dispersing blades are installed through the annular side of the drive shaft. This design solves the problem that traditional single-rotor hammer dispersers rely solely on hammer impact, resulting in mediocre dispersing effect, unevenness, and low fine powder rate of glass sand. This utility model adopts a transmission-type coarse dispersing and transmission-type fine dispersing structure, which can not only disperse the glass sand twice, but also, with the final rotary dispersing structure, can further disperse the intercepted and filtered glass sand, ensuring a high fine powder rate of glass sand.

Description

Technical Field

[0001] This utility model is a glass sand dispersing machine, belonging to the field of glass sand processing technology. Background Technology

[0002] Glass sand, due to its high hardness, corrosion resistance, and chemical stability, is widely used in casting, construction, and industrial materials. As an important raw material for glass product manufacturing, glass sand often clumps due to humid storage environments or compression during transportation, requiring pretreatment by a breaker. Traditional glass sand breakers typically employ a single-rotor hammer mill structure: a motor drives the rotor to rotate, and hammers impact the clumped glass sand, with a fixed screen at the bottom for particle size screening.

[0003] However, traditional single-rotor hammer mills rely solely on hammer impact, resulting in only moderate and uneven glass sand dispersion with a low fine powder content. There is an urgent need for a glass sand disperser to address these issues. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a glass sand dispersing machine to solve the problems mentioned in the background. This invention adopts a transmission-type coarse dispersing and transmission-type fine grinding structure, which can not only disperse the glass sand twice, but also, with the final addition of a rotary dispersing structure, can further disperse the filtered glass sand, ensuring the fine powder rate of the glass sand.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a glass sand dispersing machine, comprising a dispersing box and a conical hopper, wherein a conical hopper is welded to the lower end of the dispersing box, and an intercepting filter screen is horizontally welded inside the conical hopper. A conical sand-proof shell is installed through the middle of the intercepting filter screen by bolts. A small motor is built into the conical sand-proof shell, and the movable end of the small motor passes through the conical sand-proof shell and is fixed to the dispersing plate. A drive shaft is installed through the upper end of the dispersing box by bearings. Multiple coarse dispersing blades are installed through the annular side of the drive shaft. A first driven wheel is installed at the right end of the drive shaft. A servo motor is installed at the front end of the dispersing box by bolts. A composite drive wheel is installed at the shaft end of the servo motor. A first grinding roller and a second grinding roller are horizontally installed inside the dispersing box, and a second driven wheel is coaxially installed at the right end of the first grinding roller.

[0006] Furthermore, the lower side of the movable end of the dispersing plate slides against the surface of the intercepting filter screen.

[0007] Furthermore, a controller is bolted to the front end of the conical bucket, and the controller is connected to a servo motor and a small motor via wires.

[0008] Furthermore, the first and second grinding rollers are located directly below the multiple coarse abrasive blades, and the intercepting filter screen is located below the first and second grinding rollers.

[0009] Furthermore, a first spur gear is coaxially connected to the left end of the first grinding roller, and a second spur gear is coaxially connected to the left end of the second grinding roller, and the second spur gear meshes with the first spur gear for transmission.

[0010] Furthermore, the second driven wheel is synchronously connected to the composite transmission wheel via a second synchronous belt, and the composite transmission wheel is synchronously connected to the first driven wheel via a first synchronous belt.

[0011] The beneficial effects of this utility model are as follows: This utility model provides a glass sand dispersing machine. Because it adds coarse dispersing blades, a drive shaft, a first driven wheel, a first synchronous belt, a composite drive wheel, a servo motor, a second driven wheel, a second synchronous belt, a first grinding roller, a second grinding roller, a small motor, a conical sand-proof shell, an intercepting filter screen, and a dispersing plate, the structure is reasonable. It adopts a transmission-type coarse dispersing and transmission-type fine grinding dispersing structure, which can not only disperse the glass sand twice, but also, with the final rotary dispersing structure, can further disperse the intercepted and filtered glass sand, ensuring the fine powder rate of the glass sand and making it highly practical.

Detailed Implementation

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] Please see Figures 1-3 This utility model provides a technical solution: a glass sand dispersing machine, including a dispersing box 1 and a conical hopper 14. The conical hopper 14 is welded to the lower end of the dispersing box 1. An intercepting filter screen 18 is horizontally welded inside the conical hopper 14. A conical sandproof shell 17 is installed through the center of the intercepting filter screen 18 by bolts. A small motor 16 is built into the conical sandproof shell 17. The movable end of the small motor 16 passes through the conical sandproof shell 17 and is fixed to the dispersing plate 19. A drive shaft 3 is installed through the upper end of the dispersing box 1 by bearings. Multiple coarse dispersing blades 2 are installed through the annular side of the drive shaft 3. A first driven wheel 4 is installed at the right end of the drive shaft 3. A servo motor 7 is bolted to the front end of the dispersing box 1. A composite drive wheel 6 is installed at the shaft end of the servo motor 7. A first grinding roller 10 and a second grinding roller 13 are horizontally installed inside the dispersing box 1. A second driven wheel 8 is coaxially installed at the right end of the first grinding roller 10. This design solves the problem that the traditional single-rotor hammer disperser relies solely on hammer impact, resulting in a generally poor dispersing effect on glass sand, insufficient uniformity, and a low fine powder rate.

[0019] In the first embodiment of this utility model: the lower side of the movable end of the dispersing plate 19 slides and contacts the surface of the intercepting filter screen 18. By adding the dispersing plate 19 and sliding its lower side against the surface of the intercepting filter screen 18, the glass sand on the intercepting filter screen 18 can be dispersed when the dispersing plate 19 rotates. A controller 15 is bolted to the front end of the conical bucket 14. The controller 15 is connected to the servo motor 7 and the small motor 16 through wires. The added controller 15 is an existing mature device (PLC control device), and the control principle will not be described in detail. The first grinding roller 10 and the second grinding roller 13 are located directly below the multiple coarse grinding blades 2. The intercepting filter screen 18 is located below the first grinding roller 10 and the second grinding roller 13. The left end of the first grinding roller 10 is coaxially connected to the first spur gear 11, and the left end of the second grinding roller 13 is coaxially connected to the second spur gear 12. The second spur gear 12 meshes with the first spur gear 11 for transmission. When the first spur gear 11 rotates, it can drive the second spur gear 12 to mesh and rotate, thereby realizing the opposite rotation of the first grinding roller 10 and the second grinding roller 13.

[0020] The second driven wheel 8 is synchronously connected to the composite transmission wheel 6 via the second synchronous belt 9. The composite transmission wheel 6 is synchronously connected to the first driven wheel 4 via the first synchronous belt 5. The added second driven wheel 8 is synchronously connected to the composite transmission wheel 6 via the second synchronous belt 9. The composite transmission wheel 6 is synchronously connected to the first driven wheel 4 via the first synchronous belt 5. When the composite transmission wheel 6 rotates, it can drive the first driven wheel 4 and the second driven wheel 8 to rotate synchronously via the first synchronous belt 5 and the second synchronous belt 9.

[0021] As a second embodiment of this utility model: Glass sand to be dispersed is added into the dispersing box 1. The servo motor 7 is started, and the servo motor 7 drives the composite transmission wheel 6 to rotate. This, in turn, drives the first driven wheel 4 and the second driven wheel 8 to rotate synchronously via the first synchronous belt 5 and the second synchronous belt 9. During this process, the first driven wheel 4 drives the transmission shaft 3 and multiple coarse dispersing blades 2 to rotate, thus coarsely dispersing the added glass sand. The rotation of the second driven wheel 8 drives the first grinding roller 10 and the first spur gear 11 to rotate. When the first spur gear 11 rotates, it drives the second grinding roller 10 to rotate. The spur gear 12 meshes and rotates, thereby realizing the opposite rotation of the first grinding roller 10 and the second grinding roller 13. This can finely grind and disperse the glass sand passing between the first grinding roller 10 and the second grinding roller 13. Then, the glass sand that is not completely dispersed in the second grinding falls onto the intercepting filter screen 18, while the completely dispersed glass sand will pass through the intercepting filter screen 18. The small motor 16 is started, and the small motor 16 drives the dispersing plate 19 to rotate. When the dispersing plate 19 rotates, it can rotate and disperse the glass sand on the intercepting filter screen 18 again until it is completely dispersed and passes through the intercepting filter screen 18.
