Two rotating rollers are provided in the middle frame, and the two rotating rollers are respectively fixed on the two rotating shafts.

[0024] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0025] like Figure 1-5 As shown, a compact block material crushing device includes a middle frame 1 and a crushing mechanism 2 disposed within the middle frame 1. The crushing mechanism 2 is disposed between two symmetrical semi-circular concave plates 3. The two semi-circular concave plates 3 are disposed within the middle frame 1 and fixed by screws. The middle frame 1 is detachably installed on the inlet hopper of the screw conveyor. An upper expansion hopper 4 is integrally provided on the upper side of the middle frame 1, and the upper expansion hopper 4 is correspondingly disposed with the discharge hopper of the screw conveyor.

[0026] The crushing mechanism 2 includes two rotating shafts 31, a first gear 35, and a second gear 36. The first gear 35 and the second gear 36 are located on the outside of the intermediate frame 1 and are respectively installed on one side of the two rotating shafts 31 by key connection. The first gear 35 and the second gear 36 mesh with each other. The two rotating shafts 31 are rotatably installed in the intermediate frame 1 by bearings. Two rotating rollers 32 are provided in the intermediate frame 1. The two rotating rollers 32 are respectively fixed on the two rotating shafts 31. Two sets of crushing tooth assemblies 33 are respectively provided in the semi-circular recesses of the two semi-circular recess plates 3 in the intermediate frame 1. A drive motor 34 is installed on the side of the intermediate frame 1 by a bracket. The output shaft of the drive motor 34 is connected to one of the rotating shafts 31 by a coupling. The drive motor 34 is a servo motor, and the speed of the drive motor 34 is set at 28-35 rpm.

[0027] As an optional implementation, each set of the crushing tooth assembly 33 is configured as multiple and evenly distributed around the outer periphery of the rotating roller 32. The crushing tooth assembly 33 includes a plug plate 33a and shearing teeth 33b. The shearing teeth 33b are configured as multiple and evenly spaced and fixed on the plug plate 33a. In this way, multiple crushing tooth assemblies 33 can perform cyclic crushing processing when the rotating roller 32 rotates.

[0028] See attached document Figure 4 and attached Figure 5The insertion plate 33a is inserted into the insertion slot 32a. The insertion slot 32a consists of multiple slots that are evenly distributed around the outer periphery of the rotating roller 32. Multiple fastening screws pass through the insertion plate 33a and are located between two adjacent shear teeth 33b. The fastening screws pass through the threaded holes in the bottom surface of the insertion plate 33a and are threaded into the insertion slot 32a. This not only fixes the shear tooth assembly 33 after insertion but also facilitates subsequent replacement operations.

[0029] Furthermore, the shearing tooth 33b is a right-angled triangle, and an integral crushing blade 33c is provided on the inclined surface of the triangle. This allows the crushing blade 33c to quickly break the filter cake into pieces when it rotates, thereby cooperating with another set of shearing teeth 33b to carry out the crushing process of the filter cake.

[0030] Furthermore, the transmission ratio between the first gear 35 and the second gear 36 is set to 1:5 or higher, so that when the two rotating rollers 32 rotate relative to each other, a differential speed effect is achieved, thereby driving the two sets of crushing tooth components 33 to achieve progressive crushing of the filter cake, reducing the size of the crushed particles and improving the uniformity of crushing.

[0031] Furthermore, the crushing tooth assemblies 33 on the two rotating rollers 32 are symmetrically arranged between the two rotating shafts 31, so that the shearing teeth 33b on the two rotating rollers 32 can rotate relative to each other with the crushing blades 33c, thereby performing dual processing of crushing and segmentation, and improving the crushing smoothness.

[0032] See attached document Figure 1 and attached Figure 3 A bending protection plate 5 is installed on the other side of the intermediate frame 1 via a bolt and nut assembly. The first gear 35 and the second gear 36 are located between the outer side of the intermediate frame 1 and the bending protection plate 5. This can protect the first gear 35 and the second gear 36 when they rotate and mesh, reducing the risk of foreign objects getting stuck and affecting operation.

[0033] Using the above structure, the drive motor 34 drives one of the rotating shafts 31 to rotate via a coupling. The meshing transmission of the first gear 35 and the second gear 36 (with a transmission ratio of 1:5 or higher) enables the two rotating shafts 31 to rotate in opposite directions at different speeds, thereby driving the two rotating rollers 32 to rotate relative to each other. The evenly distributed crushing tooth components 33 on the rotating rollers 32 rotate with the rollers 32. The two sets of symmetrically arranged shearing teeth 33b form a strong shearing action under differential speed. When the filter cake material enters the middle frame 1 from the upper expansion hopper 4, it is first subjected to the shearing and biting action of the crushing tooth components 33 on the rotating rollers 32. The crushing blades 33c of the right-angled triangular shearing teeth 33b cut the material into pieces. Subsequently, under the differential shearing and extrusion action of the two sets of crushing tooth components 33, progressive crushing is achieved. During the crushing process, the crushing blades 33c of the shearing teeth 33b cooperate with the biting surface to complete the crushing-segmentation-refinement cycle of the material. The entire crushing process operates stably under the protection of the bent protective plate 5, effectively preventing foreign objects from interfering with gear meshing and ensuring continuous and efficient crushing operations.

[0034] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. All standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part all adopt conventional methods such as bolts, rivets, and welding, which are mature technologies in the prior art.

The control circuit of the controller can be implemented by simple programming by those skilled in the art, and is common knowledge in the field. Furthermore, this application is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail here. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, are implemented according to conventional methods in the field.
