Description

Technical Field

[0001] This utility model relates to the field of crusher technology, specifically a vertical crusher. Background Technology

[0002] Vertical shaft impact crushers are highly efficient crushing equipment widely used in construction, road, and bridge engineering. Material falls vertically from the top of the machine into a high-speed rotating impeller. Under high-speed centrifugal force, it collides and crushes with another portion of material diverted in an umbrella-like pattern around the impeller. A vortex then forms between the impeller and the casing, where materials are repeatedly crushed through collisions and friction, exiting directly from the bottom. This process causes material to quickly accumulate at the screen plate, resulting in a large amount of material on the screen. This increased material volume leads to more material covering the screen openings. In cases of large accumulation, material can squeeze and bridge, forming clumps that block the screen openings, hindering the flow of other material and causing screen plate blockage. Utility Model Content

[0003] In view of this, the present invention provides a vertical crusher, which aims to solve the problems in the prior art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a vertical crusher, comprising:

[0005] The crusher body has a screening box below the discharge port at its lower end, and the screening box is connected to the discharge port; the bottom of the screening box has a particle outlet.

[0006] The first screening plate is inclinedly disposed below the discharge port inside the screening box. A first discharge port is provided on the screening box on the lower side of the first screening plate, and a first screen hole is provided on the first screening plate.

[0007] The second screening plate is arranged parallel to the first screening plate below it. A second discharge port is provided on the screening box on the lower end side of the second screening plate. The second screening plate is provided with a second screen hole. The diameter of the second screen hole is smaller than that of the first screen hole. The second screening plate is connected to the first screening plate through a connector.

[0008] The vibration assembly is connected to the second screening plate and drives the second screening plate and the first screening plate to vibrate synchronously.

[0009] A further improvement of this utility model is that the lower ends of the first screening plate and the second screening plate are respectively hinged to the screening box, and the vibration assembly includes:

[0010] A lifting rod is slidably mounted on a support plate below the second screening plate. A first roller is rotatably mounted on the upper end of the lifting rod, and the outer circumferential surface of the first roller is in rolling connection with the lower surface of the second screening plate.

[0011] A first rotating shaft is horizontally positioned below the lifting rod and rotates under the drive of a first motor. An eccentric wheel is fixed on the first rotating shaft, and the outer circumferential surface of the eccentric wheel is in rolling connection with the outer circumferential surface of the second roller at the lower end of the lifting rod.

[0012] A further improvement of this utility model is that the connecting member is a first connecting rod, which is disposed on one side of the first screening plate. The upper end of the first connecting rod is hinged to the first screening plate, and the lower end of the first connecting rod is hinged to the second screening plate.

[0013] A further improvement of this utility model is that a dust removal box is provided on one side of the crusher body, and the screening box is connected to the dust removal box through a first dust extraction pipe.

[0020] The technological advancements achieved by this utility model due to the adoption of the above technical solution are as follows:

[0021] This utility model provides a vertical crusher. A first screening plate has first screen holes. Material, under its own weight and the downward force generated by the inclination angle of the first screening plate, begins the screening process on the plate surface. Material with a particle size smaller than the first screen hole diameter passes through the first screen hole and falls downwards; while material with a particle size larger than the first screen hole diameter moves along the lower end of the first screening plate and is finally discharged from the first discharge port on the lower side of the screening box. Material passing through the first screen hole continues to fall onto a second screening plate parallel to it below. The second screen plate has second screen holes with a smaller diameter than the first screen hole diameter, allowing for finer screening. Material with a particle size smaller than the second screen hole diameter passes through the second screen hole and is finally discharged from the particle outlet at the bottom of the screening box, becoming finished particles that meet the particle size requirements. Material with a particle size larger than the second sieve aperture but smaller than the first sieve aperture moves along the second screening plate towards the lower end and is discharged from the second discharge port on the screening box at the lower end of the second screening plate. The vibration assembly drives the second screening plate and the first screening plate connected to it to vibrate synchronously. The high-frequency oscillation force generated by the vibration causes the material to continuously jump and roll on the first and second screening plates. Compared with the prior art, this can prevent the material from accumulating on the first and second screening plates, reduce the occurrence of material particles squeezing each other and bridging and clogging the first and second sieve apertures, and reduce the occurrence of clogging of the first and second screening plates.

Obviously, in the following description, specific details such as particular system structures and technologies are set forth for illustrative purposes rather than for limiting purposes, in order to provide a thorough understanding of the embodiments of the present invention. However, those skilled in the art should understand that the present invention can also be implemented in other embodiments without these specific details.

[0030] The vertical crusher provided by this utility model, in conjunction with the appendix to the instruction manual... Figure 1 To be continued Figure 4 It can be seen that the vertical crusher mainly includes the following parts or components: crusher body 10, first screening plate 12, second screening plate 13, and vibration assembly 20.

[0031] In this utility model, a screening box 11 is provided below the discharge port 101 at the lower end of the crusher body 10, and the screening box 11 is connected to the discharge port 101; a particle outlet 111 is provided at the bottom of the screening box 11; a first screening plate 12 is inclinedly disposed below the discharge port 101 inside the screening box 11, and a first discharge port 112 is provided on the lower end side of the first screening plate 12 on the screening box 11, and a first screen hole 121 is provided on the first screening plate 12; a second screening plate 13 is flat. The second screening plate 13 is positioned below the first screening plate 12. A second discharge port 113 is provided on the screening box 11 on the lower end side of the second screening plate 13. A second screen hole 131 is provided on the second screening plate 13. The diameter of the second screen hole 131 is smaller than the diameter of the first screen hole 121. The second screening plate 13 is connected to the first screening plate 12 through a connector. The vibration assembly 20 is connected to the second screening plate 13 and drives the second screening plate 13 and the first screening plate 12 to vibrate synchronously.

[0032] The first screening plate 12 has a first screen hole 121. Under the action of its own gravity and the downward force generated by the inclination angle of the first screening plate 12, the material begins the screening process on the plate surface. The material with a particle size smaller than the aperture of the first screen hole 121 passes through the first screen hole 121 and falls downward; while the material with a particle size larger than the aperture of the first screen hole 121 moves along the first screening plate 12 to the lower end and is finally discharged from the first discharge port 112 set on the screening box 11 on the lower end side of the first screening plate 12. The material passing through the first screen hole 121 continues to fall onto the second screening plate 13 set parallel below. The second screen hole 131 on the second screening plate 13 has a smaller aperture than the aperture of the first screen hole 121, and performs finer screening. The material with a particle size smaller than the aperture of the second screen hole 131 passes through the second screen hole 131 and is finally discharged from the particle outlet 111 at the bottom of the screening box 11, becoming finished particles that meet the particle size requirements. Material with a particle size larger than the second sieve aperture 131 but smaller than the first sieve aperture 121 moves along the second screening plate 13 towards the lower end and is discharged from the second discharge port 113 provided on the screening box 11 on the lower end side of the second screening plate 13. The vibration assembly 20 drives the second screening plate 13 and the first screening plate 12 connected thereto to vibrate synchronously. The high-frequency oscillation force generated by the vibration causes the material to continuously jump and roll on the first screening plate 12 and the second screening plate 13, which can prevent the material from accumulating on the first screening plate 12 and the second screening plate 13, reduce the occurrence of material particles squeezing each other and bridging and clogging the first sieve aperture 121 and the second sieve aperture 131, and reduce the occurrence of clogging of the first screening plate 12 and the second screening plate 13.

[0033] Specifically, the connecting component is a first connecting rod 14, which is located on one side of the first screening plate 12. The upper end of the first connecting rod 14 is hinged to the first screening plate 12, and the lower end of the first connecting rod 14 is hinged to the second screening plate 13.

[0034] Specifically, the materials discharged from the first discharge port 112 and the second discharge port 113 will be recycled and crushed again to meet the standards.

[0035] As one embodiment, in conjunction with the appendix to the specification Figure 2 To be continued Figure 3 It is known that the lower ends of the first screening plate 12 and the second screening plate 13 are hinged to the screening box 11 respectively. The vibration assembly 20 includes a lifting rod 21, which is slidably mounted on a support plate (not shown in the figure) below the second screening plate 13. A first roller 211 is rotatably mounted on the upper end of the lifting rod 21, and the outer circumferential surface of the first roller 211 is in rolling connection with the lower surface of the second screening plate 13. The first rotating shaft 23 is horizontally mounted below the lifting rod 21 and rotates under the drive of the first motor (not shown in the figure). An eccentric wheel 25 is fixed on the first rotating shaft 23, and the outer circumferential surface of the eccentric wheel 25 is in rolling connection with the outer circumferential surface of the second roller 22 at the lower end of the lifting rod 21.

[0036] After the first motor starts, it drives the horizontally positioned first rotating shaft 23 to rotate. The eccentric wheel 25 rotates with the first rotating shaft 23. The eccentricity of the eccentric wheel 25 causes its contact position with the second roller 22 to change continuously during rotation, thus generating a periodic force on the lower end of the lifting rod 21. When the eccentric wheel 25 rotates, its outer circumferential surface pushes the second roller 22, causing the lifting rod 21 to slide up and down on the support plate. The first roller 211 at the upper end of the lifting rod 21 always maintains a rolling connection with the lower surface of the second screening plate 13. When the lifting rod 21 moves up and down, the first roller 211 causes the second screening plate 13 to vibrate up and down. Since the second screening plate 13 and the first screening plate 12 are connected by a connector, this vibration is synchronously transmitted to the first screening plate 12, causing the second screening plate 13 and the first screening plate 12 to vibrate synchronously. During vibration, the first screening plate 12 and the second screening plate 13 swing up and down about their lower ends, which are hinged to the screening box 11, respectively.

[0037] As one embodiment, in conjunction with the appendix to the specification Figure 4 It is known that a dust collection box 30 is provided on one side of the crusher body 10, and the screening box 11 is connected to the dust collection box 30 through a first dust extraction pipe (not shown in the figure). The dust collection box 30 is provided with an inlet 301 and an outlet 302. A stirring shaft 32 is provided inside the dust collection box 30. The stirring shaft 32 rotates alternately in both directions under the drive of the drive assembly. A stirring paddle 33 is fixed on the stirring shaft 32. The drive assembly includes a cylinder 41, which is fixed on the dust collection box 30. A guide post 42 is fixed at the end of its piston rod. The lower end of the second connecting rod 43 is fixedly connected to the end of the stirring shaft 32, and the elongated slot 44 at the upper end is slidably connected to the guide post 42.

[0038] Water is fed into the dust collector 30 through the inlet 301. Then, the exhaust fan is turned on, and the dust generated in the screening box 11 is sent into the water in the dust collector 30 through the first dust extraction pipe. The cylinder 41 drives the piston rod to extend and retract, and the piston rod drives the guide column 42 to slide in the long slot 44. Through the cooperation between the guide column 42 and the long slot 44, the second connecting rod 43 swings around the end of the stirring shaft 32. The second connecting rod 43 drives the stirring shaft 32 to rotate alternately in the forward and reverse directions. The stirring shaft 32 stirs the water and dust through the stirring paddle 33, so that the dust and water are fully mixed and in contact, increasing the contact area between the dust and water, which can prevent the dust from settling and accumulating in the water. After mixing, the solution of water and dust is discharged from the outlet 302.

[0039] In this embodiment, refer to the appendix to the specification. Figure 4 It can be seen that the dust collector 30 has an air outlet at the top (not shown in the figure), and a filter plate 31 is fixed on the air outlet.

[0040] Even after water treats the dust, some fine dust particles still rise with the airflow to the outlet. Filter plate 31 can intercept these residual dust particles, further improving dust removal efficiency, ensuring cleaner exhaust gas, and reducing pollution to the atmospheric environment.

[0041] In this embodiment, the dust collection box 30 is connected to the feed inlet 102 of the crusher body 10 via a second exhaust pipe (not shown in the figure). Dust is also easily generated at the feed inlet 102. By turning on another exhaust fan, the dust generated in the feed inlet 102 is sent to the water in the dust collection box 30 through the second dust extraction pipe, thereby treating the dust.
