[0025] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the scheme of the present invention will be further described below. It should be noted that, in the absence of conflict, the embodiments of the present invention and the features therein can be combined with each other.
[0026] The following description sets forth many specific details to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; it is obvious that the implementation methods in the specification are only part of the implementation methods of the present invention, not all of the implementation methods.
[0027] Combine Figures 1 to 5 As shown, the vertical dry material pulverizer provided by the embodiment of the present invention includes a pulverizer body 1, which is provided with a feed port 2 and a discharge port, a preliminary pulverizing mechanism 3, which is installed at the upper end of the interior of the pulverizer body 1, an auxiliary pulverizing component 4, which is installed on the inner wall of the pulverizer body 1, a first screen 5, which is installed inside the pulverizer body 1, the first screen 5 is located below the preliminary pulverizing mechanism 3 and the auxiliary pulverizing component 4, a grinding pulverizing mechanism 6, the stationary end of which is installed on the inner wall of the pulverizer body 1, and the lower end of the output end of the preliminary pulverizing mechanism 3 passes through the first screen 5. It is fixedly connected to the rotating end of the grinding and crushing mechanism 6, the grinding and crushing mechanism 6 is located below the first screen 5, the large particle dry material circulating grinding feed port 7 is connected to the side wall of the grinder body 1, and the connection point of the large particle dry material circulating grinding feed port 7 is located between the first screen 5 and the grinding and crushing mechanism 6, the second screen 8 is detachably connected to the inside of the grinder body 1, the second screen 8 is located below the grinding and crushing mechanism 6, the grinding and crushing mechanism 6, the second screen 8 and the large particle dry material circulating grinding feed port 7 constitute a large particle dry material circulating grinding assembly.
[0028] Thus, the dry material is effectively crushed and dehumidified through the preliminary crushing mechanism and the auxiliary crushing assembly, and the grinding and crushing mechanism grinds the dry material finely. The ground dry material falls onto the second screen. The staff takes out the second screen and pours the large-particle dry material on the second screen into the large-particle dry material circulating grinding feed port, so that the large-particle dry material enters the grinding and crushing mechanism for repeated grinding, which effectively reduces the generation of large-particle dry material and lumps and improves the quality of the product.
[0029] In some embodiments, as Figure 1 and Figure 5 As shown, the preliminary crushing mechanism 3 includes a motor 31, which is fixedly connected to the middle of the upper surface of the crusher body 1. The output end of the motor 31 passes through the upper surface of the crusher body 1 and is fixedly connected to a rotating rod 32. A plurality of reamers 33 are evenly installed on the surface of the rotating rod 32. The lower end of the rotating rod 32 passes through the first screen 5 and is fixedly connected to the rotating end of the grinding and crushing mechanism 6.
[0030] The rotating rod 32 and the penetration points of the first screen 5 and the grinder body 1 are all fixedly connected with sealed bearings.
[0031] Thus, when the dry material enters the grinder body 1 from the feed port 2, the motor 31 is started, which in turn drives the rotating rod 32 to rotate, causing the reamer 33 mounted thereon to rotate, thereby crushing the entering dry material.
[0032] In some embodiments, as Figure 1 and Figure 5 As shown, the auxiliary crushing assembly 4 includes an auxiliary reamer 41 and a drying rod 42 , and the auxiliary reamer 41 and the drying rod 42 are evenly distributed and installed on the inner wall of the crusher body 1 .
[0033] The auxiliary reamer 41 is a blade body with a blade offset in the opposite direction to the reamer 33, thereby enhancing the cutting effect and increasing the efficiency of crushing.
[0034] Therefore, when the preliminary crushing mechanism 3 is working, it drives the dry material to rotate on the inner wall of the grinder body 1, and the dry material is assisted in crushing and removing moisture through the auxiliary reamer 41 and the drying rod 42. The dry material that meets the preliminary crushing standard passes through the first screen 5 and enters the grinding and crushing mechanism 6.
[0035] In some embodiments, as Figure 1 and Figure 4 As shown, the grinding and crushing mechanism 6 includes a dynamic grinding block 61, which is fixedly connected to the lower end of the rotating rod 32, and a static grinding block 62, which is installed on the inner wall of the grinder body 1. Crushing protrusions 63 are evenly distributed on the surfaces of the dynamic grinding block 61 and the static grinding block 62.
[0036] Therefore, when the dry material enters the grinding and crushing mechanism 6, the rotation of the dynamic grinding block 61 drives the crushing protrusion 63 on it to rotate and cooperate with the crushing protrusion 63 on the static grinding block 62 to grind and crush the dry material more finely, and the ground dry material falls onto the second screen 8.
[0037] In some embodiments, as Figure 1 and Figure 3 As shown, the second screen clamping mechanism 9 includes a groove 91, which is opened on the opening, a spring 92, one end of the spring 92 is installed in the groove 91, and the other end of the spring 92 is fixedly connected with an arc-shaped protrusion 93, and a matching arc-shaped groove is opened on the second screen 8, and the arc-shaped protrusion 93 is clamped in the arc-shaped groove.
[0038] Therefore, when it is necessary to clean the large particles of dry material on the second screen 8, the second screen 8 is pulled out and the large particles of dry material on it are poured into the large particle dry material circulation grinding feed port 7, so that it re-enters the grinding and crushing mechanism 6 for re-grinding until it reaches the screening standard of the second screen 8 and then falls on the guide plate 10 and is discharged to the outside.
[0039] In some embodiments, as Figure 1 and Figure 2 As shown, a guide plate 10 is installed on the inner wall of the grinder body 1, and the guide plate 10 is located below the second screen 8. A viewing window 11 is opened on the outer wall of the grinder body 1, and the height of the viewing window 11 is the same as that of the second screen 8.
[0040] Thus, the viewing window 11 allows the staff to observe the situation on the second screen 8 more clearly.
[0041] The following is combined with Figure 1-5 Describe a specific embodiment of the utility model:
[0042] like Figure 1-Figure 5 As shown, it includes a grinder body 1, which is provided with a feed port 2 and a discharge port, a preliminary crushing mechanism 3, which is installed at the upper end of the grinder body 1, an auxiliary crushing component 4, which is installed on the inner wall of the grinder body 1, a first screen 5, which is installed inside the grinder body 1, the first screen 5 is located below the preliminary crushing mechanism 3 and the auxiliary crushing component 4, a grinding and crushing mechanism 6, the stationary end of which is installed on the inner wall of the grinder body 1, the lower end of the output end of the preliminary crushing mechanism 3 passes through the first screen 5 and is fixedly connected to the rotating end of the grinding and crushing mechanism 6, and the grinding and crushing mechanism 6 is located below the first screen 5. The large-particle dry material is circulated and ground into the feed. The opening 7 is connected to the side wall of the grinder body 1. The connection point of the large-particle dry material circulating grinding feed opening 7 is located between the first screen 5 and the grinding and crushing mechanism 6. The second screen 8 is detachably connected to the inside of the grinder body 1. The second screen 8 is located below the grinding and crushing mechanism 6. The grinding and crushing mechanism 6, the second screen 8 and the large-particle dry material circulating grinding feed opening 7 constitute a large-particle dry material circulating grinding assembly. A guide plate 10 is installed on the inner wall of the grinder body 1. The guide plate 10 is located below the second screen 8. A visual window 11 is opened on the outer wall of the grinder body 1. The height of the visual window 11 is the same as that of the second screen 8.
[0043] In actual use, when the dry material enters the grinder body 1 from the feed port 2, the motor 31 is started, which in turn drives the rotating rod 32 to rotate, causing the reamer 33 installed thereon to rotate, crushing the dry material entering and driving the dry material to rotate on the inner wall of the grinder body 1. The dry material is assisted in crushing and removing moisture through the auxiliary reamer 41 and the drying rod 42. The dry material that meets the preliminary crushing standard passes through the first screen 5 and enters the grinding and crushing mechanism 6. After the dry material enters the grinding and crushing mechanism 6, the rotation of the dynamic grinding block 61 drives the crushing protrusion 63 on it to rotate and rub against the static grinding block 6. 2 cooperates to grind the dry material more finely, and the ground dry material falls onto the second screen 8. When the large particles of dry material on the second screen 8 need to be cleaned, the second screen 8 is pulled out and the large particles of dry material on it are poured into the large particle dry material circulation grinding feed port 7, so that it re-enters the grinding and crushing mechanism 6 for re-grinding until it reaches the screening standard of the second screen 8 and then falls on the guide plate 10 and is guided to the outside. The viewing window 11 allows the staff to observe the situation on the second screen 8 more clearly, effectively reducing the generation of large particles of dry material and agglomerates, and improving the quality of the product.
