[0001] The present invention relates to the technical field of crushers, and specifically to an efficient double-roll crusher. Background Art

[0002] As a core device in the field of material crushing, the double-roll crusher is widely used in industries such as mining, metallurgy, building materials, and solid waste treatment. It crushes materials by squeezing and shearing them with two oppositely rotating roll wheels. However, the traditional double-roll crusher has the following deficiencies in practical applications: when crushing high-humidity and sticky materials (such as clay and oily metal waste), the crushed materials are easily adhered to the surface of the roll wheels, forming a stacking layer, and it is difficult to efficiently scrape off the sticky materials; at the same time, when crushing metal materials, magnetic impurities are generated, which are easily accumulated in the bottom frame and are difficult to efficiently handle and transfer. Based on this, the inventor has studied and proposed this case. Summary of the Invention

[0033] As Figures 1 - 10 shown, a high-efficiency double-roll crusher includes a bottom crushing frame 1, a top crushing frame 2, a first roller 3, a second roller 4, a driving device 5, a scraping component 6, and a magnetic adsorption component 7. The first roller 3 is installed on the bottom crushing frame 1, and the second roller 4 is installed on the top crushing frame 2. The first roller 3 and the second roller 4 are arranged facing each other. The first roller 3 is controlled to rotate by the driving device 5. A scraping component 6 for scraping the raw materials sticking to the rollers in real time is provided on the bottom crushing frame 1 and / or the top crushing frame 2. A magnetic adsorption component 7 for adsorbing magnetic impurities is provided on the inner side surface of the crushing frame and / or the top crushing frame 2. Several scraping components 6 and magnetic adsorption components 7 are provided.

[0034] According to some embodiments of the present invention, optionally, the first roller 3 is installed on one side of the bottom crushing frame 1, the second roller 4 is installed on one side of the top crushing frame 2, and the other ends of the bottom crushing frame 1 and the top crushing frame 2 are buffered at intervals by an air spring 8.

[0035] According to some embodiments of the present invention, optionally, a supporting foot 9 is lockingly installed on the bottom crushing frame 1.

[0036] According to some embodiments of the present invention, optionally, the scraping component 6 includes an erection rod 61, an erection bracket 62, a foundation seat 63, an adjusting part 64, a connecting part 65, a mounting plate 66, and a scraper 67. The erection rod 61 is installed on the erection bracket 62 in the vertical direction. The bottom end of the erection rod 61 is connected to the foundation seat 63. One end of the adjusting part 64 is lockingly installed on the foundation seat 63 through a screw 68 and a nut 69. The other end of the adjusting part 64 is connected to the connecting part 65 through a rod body 610. The bottom end of the connecting part 65 is connected to the mounting plate 66. A scraper 67 is lockingly installed on the mounting plate 66.

[0037] According to some embodiments of the present invention, optionally, a scale ruler 10 is installed on the mounting plate 66, scale lines can be set on the corresponding panel of the crusher, and the distance between the edge end of the mounting plate 66 and the roller is measured by using the scale ruler 10. When presetting the position of the scraper 67, the scraper 67 is brought into contact with the roller. At this time, the distance value measured by the scale ruler 10 is A. When the distance value is greater than A, it indicates that there is a gap between the scraper 67 and the roller and they are not in contact with each other.

[0038] According to some embodiments of the present invention, optionally, the magnetic adsorption assembly 7 is an electromagnet, and the electromagnet includes an iron core and a conductive winding wound around the outside of the iron core. When the conductive winding of the electromagnet is energized, it will have magnetism, and at this time, it can adsorb the debris generated by the crusher when crushing metal materials.

[0039] According to some embodiments of the present invention, optionally, an air extraction assembly 11 for absorbing iron filings is installed at the bottom side end of the first roller 3 and / or the second roller 4. After crushing, the materials with larger sizes are easy to transfer, but when some fine debris falls onto the bottom crushing frame 1, it is difficult to clean or transfer them efficiently. At this time, the air extraction assembly 11 efficiently transfers the debris scattered during the crushing of the crusher, reducing the possibility of it transferring to the bottom crushing frame 1 and reducing the subsequent cleaning workload.

[0040] According to some embodiments of the present invention, optionally, the air extraction assembly 11 includes a high-pressure vortex blower 111, an absorption pipeline 112, and a collection container 113. The absorption pipeline 112 is distributed at the bottom side end of the first roller 3 and the second roller 4, and the high-pressure vortex blower 111 is in communication with the absorption pipeline 112 and the collection container 113. The high-pressure vortex blower 111 is suitable for the fine iron filings and dust generated in metal processing. By generating wind through the high-pressure vortex blower, the iron filings on the side of the absorption pipeline 112 communicating with the roller are transferred into the collection container 113.

[0041] According to some embodiments of the present invention, optionally, the driving device 5 includes a driving motor 51 and a speed reducer 52. The driving end of the driving motor 51 is installed with a driving pulley 53, the input end of the speed reducer 52 is installed with a driven pulley 54, the output end of the speed reducer 52 is linked with the first roller 3 through a coupling 55, and the driving pulley 53 is linked with the driven pulley 54 through a belt.

[0042] According to some embodiments of the present invention, optionally, bearings 12 are installed at the side ends of the first roller 3 and the second roller 4.

[0043] Embodiment 1

[0044] As Figures 1 - 5As shown in the figure, this embodiment provides an efficient double-roll crusher, which includes a bottom crushing frame 1, a top crushing frame 2, a first roll 3, a second roll 4, a driving device 5, and a scraping assembly 6. The first roll 3 is installed on the bottom crushing frame 1, and the second roll 4 is installed on the top crushing frame 2. The first roll 3 and the second roll 4 are arranged facing each other. The first roll 3 is controlled to rotate by the driving device 5. A scraping assembly 6 for scraping the raw materials adhered to the rolls in real time is arranged on the bottom crushing frame 1 and / or the top crushing frame 2, and several scraping assemblies 6 are provided.

[0045] The first roll 3 is installed on one side of the bottom crushing frame 1, and the second roll 4 is installed on one side of the top crushing frame 2. The other ends of the bottom crushing frame 1 and the top crushing frame 2 are spaced and buffered by an air spring 8. A supporting foot 9 is locked and installed on the bottom crushing frame 1. The scraping assembly 6 includes a mounting rod 61, a mounting bracket 62, a base seat 63, an adjusting member 64, a connecting member 65, a mounting plate 66, and a scraper 67. The mounting rod 61 is installed on the mounting bracket 62 in the vertical direction. The bottom end of the mounting rod 61 is connected to the base seat 63. One end of the adjusting member 64 is locked and installed on the base seat 63 through a screw 68 and a nut 69. The other end of the adjusting member 64 is connected to the connecting member 65 through a rod body 610. The bottom end of the connecting member 65 is connected to the mounting plate 66. The scraper 67 is locked and installed on the mounting plate 66. The driving device 5 includes a driving motor 51 and a speed reducer 52. The driving end of the driving motor 51 is installed with a driving pulley 53. The input end of the speed reducer 52 is installed with a driven pulley 54. The output end of the speed reducer 52 is linked with the first roll 3 through a coupling 55. The driving pulley 53 is linked with the driven pulley 54 through a belt. Bearings 12 are installed at the side ends of the first roll 3 and the second roll 4.

[0046] The driving motor 51 drives the speed reducer 52 through belt transmission. The output end of the speed reducer 52 drives the first roll 3 to rotate. The material enters the gap between the two rolls from the feeding port and is crushed under the extrusion and shearing action of the rolls. The surface of the rolls can be designed as a toothed shape or a smooth surface to adapt to different hardness materials. When it is a smooth surface, high-hardness wear-resistant alloy steel can be used. The adjustment of the scraper 67 is mainly achieved by changing the angle between the adjusting member 64 and the base member, realizing fine adjustment of the distance from the roll surface, and ensuring close contact with the roll surface. The scraper 67 continuously scrapes the adhered materials during the rotation of the rolls to prevent blockage of the roll gap.

[0047] Embodiment 2

[0048] Further refer to Figure 6, this embodiment provides an efficient double-roll crusher. The difference between this embodiment and Embodiment 1 is that magnetic adsorption components 7 for adsorbing magnetic impurities are provided on the inner side surfaces of the bottom crushing frame 1 and / or the top crushing frame 2, and several magnetic adsorption components 7 are provided. The magnetic adsorption components 7 are electromagnets, and each electromagnet includes an iron core and a conductive winding wound around the outside of the iron core; after the electromagnet is powered on, the conductive winding wound around the iron core generates a magnetic field to adsorb the magnetic impurities in the material; after the electromagnet is powered off, the magnetism disappears, which is convenient for centralized cleaning of the adsorbed magnetic impurities. A scale ruler 10 is installed on the mounting plate 66, and the scale ruler 10 detects the offset of the scraper 67.

[0049] Embodiment 3

[0050] As Figure 7 shown, this embodiment provides an efficient double-roll crusher. The difference between this embodiment and Embodiment 2 is that in this efficient double-roll crusher, a suction component 11 for absorbing iron filings is installed at the bottom end of the first roll 3 and / or the second roll 4. The suction component 11 includes a high-pressure vortex blower 111, a suction pipe 112, and a collection container 113. The suction pipe 112 is distributed at the bottom end of the first roll 3 and the second roll 4, and the high-pressure vortex blower 111 is communicated with the suction pipe 112 and the collection container 113.

[0051] The suction component 11 is arranged at the bottom side of the roll to suck the scattered magnetic impurities during the crushing process and transfer them to the collection container 113, which is convenient for centralized treatment of the magnetic impurities and avoids their adsorption on the inner walls of the bottom crushing frame 1 and the top crushing frame 2, making it inconvenient to clean after long-term use.

[0052] Embodiment 4

[0053] As Figures 7 - 10 shown, this embodiment provides an efficient double-roll crusher. The difference between this embodiment and Embodiment 3 is that a valve plate 1121 is arranged in the suction pipe 112, and a through hole 1122 is penetrated through the valve plate 1121. The valve plate 1121 is controlled to rotate by a motor 1131. Usually, the suction pipe 112 has a cylindrical structure and its cross-section is circular, and the valve plate 1121 is circular; when the main side surface 1123 (circular side surface) of the valve plate 1121 faces the gas flow direction, the air flow enters from the through hole 1122, which is the Figure 7 state in the figure; when the secondary side surface 1124 of the valve plate 1121 faces the gas flow direction, at this time, the gas flow space in the suction pipe 112 becomes larger, which is the Figure 8 state in the figure.

[0054] A flow port 1125 is locally arranged on the absorption pipeline 112. A closing piece 1126 is arranged on the outer side surface of the absorption pipeline 112. The closing piece 1126 slides along the outer wall of the absorption pipeline 112 to cover or open the flow port 1125 through the closing piece 1126. The displacement of the closing piece 1126 is controlled by an air rod 1127. An independent container 1128 is arranged at the bottom end of the flow port 1125 for collection. When the main side surface 1123 (circular side surface) of the valve piece 1121 faces the gas flow direction and the high-pressure vortex blower 111 is started, an air flow is generated in the absorption pipeline 112, and debris will be mixed in. When the size of the debris is smaller than the size of the flow hole 1122, it will directly pass through the valve piece 1121; otherwise, it will be blocked by the valve piece 1121. First, the high-pressure vortex blower 111 is turned off, and the debris blocked on the valve piece 1121 falls to the flow port 1125. Then, the movement of the closing piece 1126 is controlled by the air rod 1127 to open the flow port 1125, and the debris will fall downward into the independent container 1128 for collection.

[0055] The above structure in this embodiment is beneficial to efficiently screening out and transferring large-particle debris to the independent container 1128 for collection at the front end. On the one hand, the design of the independent container 1128 and the collection container 113 increases the debris collection amount and improves the processing efficiency. On the other hand, it can reduce the risk of large-particle debris blocking in the absorption pipeline 112 and also reduce the burden on the high-pressure vortex blower 111, so that small debris that meets the requirements can be efficiently transferred to the collection container 113 by the high-pressure vortex blower 111. The absorption pipeline can be divided into a transverse pipeline 1129 and a longitudinal pipeline 1130. The structures of the flow port 1125, the closing piece 1126, and the valve piece 1121 are arranged on the transverse pipeline 1129, and multiple transverse pipelines 1129 can be arranged according to requirements.

[0056] The above is only a preferred embodiment of the present invention, so the scope of implementation of the present invention cannot be limited thereby. That is, equivalent changes and modifications made according to the scope of the present invention patent and the content of the specification should still fall within the scope covered by the present invention.
