For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances. Specific embodiments:

[0028] For example, Figures 1-3As shown, the present application provides a kind of broken device of slag material, including shell 1, the top of shell 1 is equipped with feed inlet 2, the bottom of shell 1 is equipped with discharge outlet 3, shell 1 is equipped with crushing assembly 4, shell 1 is equipped with the drive assembly 5 of driving crushing assembly 4 operation, shell 1 is equipped with dust removal assembly 6, dust removal assembly 6 includes dust cover 61, dust removal fan 62, dust removal pipe 63, dust collection box 64 and dust exhaust pipe 65, dust cover 61 covers in feed inlet 2, the top of dust cover 61 is equipped with feed hopper 7, dust collection box 64 is fixed in the side of shell 1, one side of dust cover 61 is connected with dust collection box 64 by dust removal pipe 63, dust removal fan 62 is equipped on dust removal pipe 63, the bottom of dust collection box is connected with the lower part of shell 1 by dust exhaust pipe 65, by dust cover 61 cover feed inlet 2, and top has feed hopper 7, can effectively control dust when entering slag material, prevent dust from spreading to the surrounding environment in the stage of feeding, reduce air pollution, meet environmental protection requirements, help to protect the quality of surrounding environment, dust removal fan 62 is installed on dust removal pipe 63, can extract dust-containing air in dust cover 61 at feed inlet 2 to dust collection box 64, ensures the high efficiency of dust collection, makes the dust amount in working area greatly reduce, avoids dust to influence the health condition of work place, reduces the opportunity of operator to contact dust, reduces the risk of health problems such as respiratory diseases caused by inhaling dust.

[0029] As Figure 3 And Figure 4 As shown, the top of dust collection box 64 is equipped with exhaust hole, the exhaust hole is equipped with filter assembly 8, dust exhaust valve 9 is equipped on dust exhaust pipe 65, the exhaust hole in the top of dust collection box 64 is used to discharge air in dust collection box 64, when dust-containing air is settled in dust collection box 64, air flows upwards and is discharged from exhaust hole, and filter assembly 8 arranged at exhaust hole can effectively intercept residual fine dust particles, prevent these dust from escaping into the working environment again with exhaust, avoid secondary pollution of dust, ensure that dust problem that has been controlled will not be deteriorated again in the process of collecting dust, keep the air of work place clean, by dust exhaust valve 9, the dust collected in dust collection box 64 can be controlled to be discharged into shell 1, so that this part of dust is recycled with slag material after crushing and is discharged from discharge outlet 3 to next process.

[0030] As Figure 4As shown, the filter assembly 8 comprises a filter mesh frame 81 and a filter sponge 82, the filter mesh frame 81 is clamped at the exhaust hole, the periphery of the filter mesh frame 81 is bent upwards to form a containing groove, and the filter sponge 82 is embedded in the containing groove, the filter mesh frame 81 and the filter sponge 82 in the filter assembly 8 constitute a double-layer filtering structure. The filter mesh frame 81 can preliminarily intercept larger dust particles to prevent them from being discharged with the exhaust. The filter sponge 82 can further filter fine dust particles. For fine dust particles that may pass through the pores of the filter mesh frame 81, the filter sponge 82 can effectively adsorb and trap them due to its porous characteristics. This double-layer filtering mechanism greatly improves the filtering efficiency of dust in the exhaust, ensuring that the discharged air is cleaner. The filter mesh frame 81 is clamped at the exhaust hole, making the installation process of the filter assembly 8 very simple. The operator does not need complex tools or professional skills to easily install the filter mesh frame 81 in place.

[0031] As shown in Figure 3 The crushing assembly 4 comprises a first rotating shaft 41, a second rotating shaft 42, a first crushing roller 43, and a second crushing roller 44. The first crushing roller 43 is rotatably arranged in the housing 1 by the first rotating shaft 41. The second crushing roller 44 is rotatably arranged in the housing 1 by the second rotating shaft 42. The first crushing roller 43 and the second crushing roller 44 are oppositely arranged. When the slag material enters the housing 1 from the feed inlet 2 and falls between the first crushing roller 43 and the second crushing roller 44, the oppositely rotating first crushing roller 43 and the second crushing roller 44 can generate strong extrusion force and shear force on the slag material, effectively crushing the slag material.

[0032] As shown in Figure 2 The driving assembly 5 comprises a driving motor 51, a mounting seat 52, a first gear 53, and a second gear 54. The driving motor 51 is fixedly arranged on the housing 1 by the mounting seat 52. The first rotating shaft 41 and the second rotating shaft 42 extend to the outside of the housing 1. The outer end of the first rotating shaft 41 is connected with the output shaft of the driving motor 51. The first gear 53 is fixedly arranged on the outer end of the first rotating shaft 41. The second gear 54 is fixedly arranged on the outer end of the second rotating shaft 42. The first gear 53 is engaged with the second gear 54. The first rotating shaft 41 is driven to rotate by the driving motor 51, which drives the first crushing roller 43 and the first gear 53 to rotate. The first gear 53 drives the second gear 54 to rotate, which drives the second rotating shaft 42 to rotate, and the second rotating shaft 42 drives the second crushing roller 44 to rotate. The engagement of the first gear 53 and the second gear 54 enables the first crushing roller 43 and the second crushing roller 44 to move synchronously and oppositely, ensuring that the slag material receives uniform extrusion force and shear force after entering the crushing area, making the crushing process more uniform and complete.

[0033] As shown in Figure 3As shown, a material guiding assembly 10 is provided inside the housing 1 above the crushing assembly 4. The material guiding assembly 10 includes a first material guiding plate 101 and a second material guiding plate 102. The first material guiding plate 101 and the second material guiding plate 102 are fixed inside the housing 1. The first material guiding plate 101 and the second material guiding plate 102 are arranged in an inverted V-shape. When the raw slag falls from the feed inlet 2, the inverted V-shaped first material guiding plate 101 and second material guiding plate 102 will guide the material to flow to both sides, so that the material can cover the area between the first crushing roller 43 and the second crushing roller 44 more widely, and avoid the raw slag from concentrating on a certain position of the first crushing roller 43 or the second crushing roller 44, which would lead to local excessive wear or uneven crushing.

[0034] like Figure 3 As shown, an inclined plate 11 is fixed inside the housing 1. The inclined plate 11 is located below the crushing component 4. The inclined plate 11 can guide the crushed slag material. The crushed slag material will slide down naturally along the inclined plate 11 under the action of gravity. The connection between the dust discharge pipe 65 and the housing 1 is located below the inclined plate 11. When the dust collected in the dust collection box 64 is discharged into the lower part of the housing 1 through the dust discharge pipe 65, the inclined plate 11 can block this part of the dust to a certain extent, preventing the dust from moving upward and affecting the airflow stability inside the housing 1, and ensuring stable material feeding.

[0035] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
