Description

Technical Field

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

[0002] In industries such as mining, building materials, and chemical engineering, double-roll crushers are widely used in the medium and fine crushing operations of medium-hard materials (such as coal, limestone, gypsum, etc.). Traditional double-roll crushers usually crush materials by the relative rotation of two rolls. However, in practical applications, when crushing materials with high humidity or large mud content, the surface of the crushing rolls is prone to adhere to mud, resulting in a decrease in crushing efficiency. Therefore, there is an urgent need for a new type of swing double-roll crusher that can effectively cope with the influence of sticky and wet materials while ensuring high-efficiency crushing, and improve the stability and service life of the equipment. Summary of the Invention

The crushing roll is installed on the base frame. The mating roll is installed on the swing frame. The swing frame changes the distance between the mating roll and the crushing roll through an adjusting device, specifically realized indirectly through pitch adjustment. The output end of the driving device is connected to drive the crushing roll. High-hardness wear-resistant alloy steel is provided on the surfaces of the crushing roll and the mating roll. A limiting plate extending to the side end of the mating roll is provided at the side end of the crushing roll.

[0037] Example 1

[0038] As Figures 1-3 shown, this embodiment provides a swing double-roll crusher, which includes a base frame 1, a swing frame 2, a driving device 3, a crushing roller 4, and a mating roller 5. The swing frame 2 is hinged to the base frame 1. The crushing roller 4 is installed on the base frame 1. The mating roller 5 is installed on the swing frame 2. The swing frame 2 changes the distance between the mating roller 5 and the crushing roller 4 through an adjusting device 6. The output end of the driving device 3 is connected to drive the crushing roller 4. High-hardness wear-resistant alloy steel 7 is provided on the surfaces of the crushing roller 4 and the mating roller 5. A limiting plate 8 extending to the side end of the mating roller 5 is provided at the side end of the crushing roller 4. The adjusting device 6 is a hydraulic cylinder.

[0039] The crushing roller 4 is installed on the base frame 1 through a first shaft rod 41, and bearings 9 are installed at both ends of the first shaft rod 41. The mating roller 5 is installed on the swing frame 2 through a second shaft rod 51, and bearings 9 are installed at both ends of the second shaft rod 51. The driving device 3 includes a driving motor 31 and a speed reducer 32. A driving pulley 311 is installed at the driving end of the driving motor 31. A driven pulley 321 is installed at the input end of the speed reducer 32. The output end of the speed reducer 32 is linked with the first shaft rod 41 through a coupling 322. The driving pulley 311 is linked with the driven pulley 321 through a belt. A protection device is provided between the base frame 1 and the swing frame 2. The protection device includes a limiting head 10, and the limiting head 10 is fixedly installed at the side end of the swing frame 2. Buffer pads 11 are installed at the bottom ends of the base frame 1 and the swing frame 2. A scraper 12 is provided at the bottom end of the crushing roller 4.

[0040] Working principle: The driving motor 31 drives the driven pulley 321 of the speed reducer 32 to rotate through the driving pulley 311 and the belt. After deceleration, the first shaft 41 and the crushing roller 4 on the first shaft 41 are driven through the coupling 322. The crushing roller 4 serves as the driving roller and contacts the material through the high-hardness wear-resistant alloy steel 7 on the surface, generating shear force and extrusion force; the mating roller 5 serves as the driven roller and rotates passively under the friction of the material. The swing frame 2 is connected to the base frame 1 through a hinge and can swing around the hinge point.

[0041] The limiting plate 8 enables the crushing roller 4 and the mating roller 5 to be accurately aligned during use, effectively avoiding the adverse effects caused by the displacement of the mating roller 5 after long-term use, and indirectly improving the service life of the crusher. When the surface of the broken item is mixed with wet soil, some of the high-hardness wear-resistant alloy steel 7 on the crushing roller 4 will be stained with wet soil. When the soil is too thick, when the crushing roller 4 rotates, the soil exceeding the thickness is blocked by the scraper 12, reducing the amount of soil on the high-hardness wear-resistant alloy steel 7. Since the debris on the crushing roller 4 is cleaned to a certain extent, the crushing effect of the crusher is improved.

[0042] Embodiment 2

[0043] As Figures 1-4 shown, this embodiment provides a swing double-roll crusher. The difference between this embodiment and Embodiment 1 is that the following structure is further provided on the basis of Embodiment 1: The base frame 1 and / or the swing frame 2 are provided with a temperature-raising device 13 for raising the surface temperature of the high-hardness wear-resistant alloy steel 7. The temperature-raising device 13 includes a blower 131, an air supply pipe 132, an air outlet hood 133, and a heating wire 134. The blower 131 is communicated with the air supply pipe 132, the air supply pipe 132 is communicated with the air outlet hood 133, and the heating wire 134 is installed on the air outlet hood 133.

[0044] To improve the efficiency of the crusher in removing soil, the surface temperature of the crushing roller 4 and the mating roller 5 is raised through the temperature-raising device 13, so that the dryness of the soil is increased. Even if there is still soil remaining on the high-hardness wear-resistant alloy steel 7, due to being drier, its viscosity decreases, making the soil easier to separate from the crushing roller 4, thereby improving the soil removal effect. The blower 131 is installed through a mounting bracket. When the blower 131 is started, it outputs wind power, which is sent into the air outlet hood 133 through the air supply pipe 132 and outputs hot air after being heated by the heating wire 134 on the air outlet hood 133; and the air outlet hood 133 is installed facing the crushing roller 4, thereby raising the surface temperature of the corresponding position of the crushing roller 4; The temperature-raising device 13 is not limited to being set to one, and multiple ones can be set, or through pipeline layout, the hot air can be transmitted to different positions of the crushing roller 4, as Figure 4 shown, the pipeline layout connecting different air outlet hoods 133 in the figure is not shown.

[0045] The above are only the preferred embodiments of the present invention, and thus 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.
