A cleaning piece is arranged in the crushing box 1, adjacent to one group of crushing rollers, for cleaning the material adhered to the crushing rollers. An adjustable blocking mechanism is installed on the inner top wall of the crushing box 1, located above the two groups of crushing rollers, for adjusting the material flow to the designated crushing roller group.

[0032] A feeding hopper 2 is fixedly connected to the top of the crushing box 1 by bolts, for introducing the material to be crushed into the crushing box 1; support legs 4 are fixedly arranged at the four corners of the bottom of the crushing box 1.

[0033] In the crushing process of the refractory material raw material, how to effectively optimize the pretreatment of the material is the key to improving the crushing efficiency and product quality. Figures 1-3 The crushing mechanism 3 comprises a driving motor 301, a cutter ring cutting roller 304 and a textured stable grinding roller 305, the driving motor 301 is installed on one side of the crushing box 1, a plurality of bearings 303 are fixed on the two sides of the crushing box 1, the inner rings of the bearings 303 are all fixed with rotating columns, a plurality of rotating columns on one side of the crushing box 1 are all fixedly connected with transmission gears 302, the adjacent two transmission gears 302 are meshed with each other, and the output end of the driving motor 301 is fixed with one of the transmission gears 302. The crushing rollers comprise a group of cutter ring cutting rollers 304 and a group of textured stable grinding rollers 305, the two ends of each two cutter ring cutting rollers 304 and each two textured stable grinding rollers 305 are fixed with one end of the rotating column, the outer surfaces of the cutter ring cutting rollers 304 are all fixed with crushing knives in the shape of a ring, and the outer surfaces of the textured stable grinding rollers 305 are provided with anti-skid lines.

[0034] A plurality of bearings 303 are fixed on the two sides of the crushing box 1, the inner rings of the bearings are closely connected with the rotating columns, and the rotating columns constitute the rotating support of the crushing rollers.

[0035] Each rotating column on one side of the crushing chamber 1 is fixedly connected to a transmission gear 302, and adjacent transmission gears are meshed to ensure smooth power transmission among multiple gears. The output end of the drive motor 301 is closely connected to one of the transmission gears 302. Once the motor starts, it can drive all rotating columns to rotate synchronously through the gear transmission system.

[0036] The crushing roller section consists of a set of blade ring cutting rollers 304 and a set of textured grinding rollers 305. Both ends of every two blade ring cutting rollers 304 and every two textured grinding rollers 305 are firmly fixed to one end of a rotating column, forming a stable rotating structure. The outer surface of the blade ring cutting rollers 304 is uniformly covered with ring-shaped crushing blades. These sharp blades can quickly cut large pieces of raw material, achieving initial crushing. The outer surface of the textured grinding rollers 305 is provided with anti-slip textures. These textures further refine the particle size of the material during rotation and reduce slippage and wear on the roller surface.

[0037] Implementation 1: Refer to Figure 1 , Figure 5 The blocking mechanism includes a rotating shaft 501 and a baffle 502. The rotating shaft 501 is rotatably connected to the upper inner wall of the crushing box 1, and the blocking mechanism is located between two sets of crushing rollers. The baffle 502 is fixed to the side wall of the rotating shaft 501 by bolts. The wrench 5 is located on the outer side wall of the crushing box 1 and is fixed to one end of the rotating shaft 501.

[0038] In this embodiment, the rotating shaft 501 is stably rotatably connected to the upper inner wall of the crushing chamber 1 and is located between the two sets of crushing rollers (blade ring cutting roller 304 and textured grinding roller 305), providing a support point for the rotation of the baffle 502. The baffle 502 is tightly fixed to the side wall of the rotating shaft 501 by bolts, and its installation angle can be adjusted as needed. For ease of operation, a wrench 5 is provided on the outer side wall of the crushing chamber 1 and fixed to one end of the rotating shaft 501. By rotating the wrench 5, the angle of the baffle 502 can be easily adjusted, thereby precisely controlling the flow direction of the material and enabling it to enter the designated crushing roller group for processing according to a predetermined path.

[0039] Example 2: A baffle with a filter screen is fixed to the side wall of the rotating shaft 501 by bolts for pre-filtering materials.

[0040] On the basis of Embodiment 1, the baffle 502 is improved in this embodiment, that is, a baffle with a filter screen is fixed on the side wall of the rotating shaft 501 by bolts. This design not only retains the function of adjusting the flow direction of the material, but also adds the link of pre-filtering the material. The filter screen can effectively intercept and remove large impurities or materials that do not meet the particle size requirements in the raw materials, ensuring that the raw materials entering the crushing roller are more pure and uniform. In this way, not only the work burden of the crushing roller is reduced, the crushing efficiency is improved, but also the quality and consistency of the final product are improved.

[0041] By adding the guide plate 6, the distribution plate 7 and the discharge plate 8, precise control and distribution refinement of the material flow direction are realized, referring to Figure 1 、 Figure 3 The top wall of the crushing box 1 is also fixed with a guide plate 6, and the guide plate 6 is provided with a groove matched with the baffle 502 to guide the material flow to the designated crushing roller group. The inner side of the crushing box 1 is provided with a distribution plate 7, which is located between the guide plate 6 and the crushing roller, for further refining the material distribution. The bottom of the crushing box 1 is fixed with a discharge plate 8, which is separated along the partition between the two groups of crushing rollers to facilitate the collection of the processed material.

[0042] The guide plate 6 is provided with a groove matched with the baffle 502. This design allows the baffle 502 to closely match the groove of the guide plate 6 when adjusted to a specific angle, and together guide the material to flow to the designated crushing roller group along the predetermined path. This precise material guiding mechanism effectively avoids the disorderly flow and accumulation of the material, improving the continuity and stability of the crushing process.

[0043] Further, the inner side of the crushing box 1 is also provided with a distribution plate 7, which is located between the guide plate 6 and the crushing roller. The function of the distribution plate 7 is to further refine the distribution of the material that has been preliminarily guided. Through its specific shape and arrangement, the distribution plate 7 can uniformly disperse the material to the working area of the two groups of crushing rollers, ensuring that each crushing roller is fully utilized, thereby improving the overall crushing efficiency.

[0044] In addition, the bottom of the crushing box 1 is also fixed with a discharge plate 8. The discharge plate 8 is separated along the partition between the two groups of crushing rollers to form two independent discharge channels. This design not only facilitates the collection of processed materials, but also allows for the classification and collection of materials of different crushing degrees as needed. At the same time, the partitioned discharge plate can effectively prevent the mixing and contamination of materials during the discharge process, ensuring the quality

[0045] During the crushing process, the knife ring cutting roller as a key component, its surface often attached a large number of material residues, this not only will affect the crushing efficiency, but also may exacerbate the equipment wear, referring to Figure 1 、 Figure 4The cleaning piece includes a fixed plate 9 arranged in the crushing box 1 and adjacent to the knife ring cutting roller 304, and the fixed plate 9 is provided with separation grooves 10 corresponding to the crushing knife gaps on the knife ring cutting roller 304.

[0046] The fixed plate 9 is carefully arranged inside the crushing box 1 and is located adjacent to the knife ring cutting roller 304. Such a layout ensures that the cleaning piece 9 can directly act on the working area of the knife ring cutting roller, achieving a high cleaning effect. The fixed plate 9 is provided with separation grooves 10 corresponding to the crushing knife gaps on the knife ring cutting roller 304. These separation grooves 10 can closely penetrate the arrangement and gaps of the crushing knives on the knife ring cutting roller, so that when the knife ring cutting roller rotates, the material residues adhering to the crushing knives are guided into the separation grooves 10 by the gravity and centrifugal force of the material itself, and then discharged out of the crushing box.

[0047] This design not only simplifies the cleaning process and reduces the need for manual intervention, but also significantly improves the cleaning efficiency. As the knife ring cutting roller continues to rotate, the separation grooves 10 continuously strip and discharge the material residues from the crushing knives, ensuring the cleanliness and sharpness of the surface of the knife ring cutting roller 304, thereby maintaining the continuity and efficiency of the crushing process.

[0048] The working principle of the raw material crushing device for producing refractory bricks is as follows: when the device is used, first, adjust the baffle 502 according to different raw materials, rotate the wrench 5 to drive the rotating shaft 501 and the baffle 502 to rotate, and the baffle 502 is attached to the guide plate 6 after rotating to the upper side of one of the crushing rollers. At this time, the material will flow into the other crushing roller along the guide plate 6 and the baffle 502. Place the raw material in the feed hopper 2, and the material flows into one of the crushing rollers along the guide plate 6 and the baffle 502. Start the drive motor 301, and the output shaft of the drive motor 301 drives one of the transmission gears 302 to rotate, which in turn drives the other three transmission gears 302 to rotate. The transmission gears 302 drive the two sets of crushing rollers to rotate through the rotating columns. One of the crushing rollers crushes the material, and the knife ring cutting roller 304 rotates through the separation grooves 10 on the fixed plate 9, which can push out the material stuck in the crushing knives of the knife ring cutting roller 304.

[0049] When replacing the baffle 502 with a filter screen, the material can be pre-filtered. Larger material particles are difficult to crush, so larger particles of material are filtered out and crushed externally after pre-crushing.
