Technical Field

[0001] This utility model relates to the technical field of refractory bricks, specifically to a raw material crushing device for refractory brick production. Background Technology

[0002] Refractory bricks, also known as fire bricks, are refractory materials made from refractory clay or other refractory raw materials. Refractory bricks are light yellow or brownish in color and can withstand high temperatures of 1580℃-1770℃. Refractory bricks are generally divided into two types: unshaped refractory bricks and shaped refractory bricks. Refractory bricks are mainly used for lining smelting furnaces and can be used as high-temperature building materials and structural materials for building kilns and various thermal equipment. They can withstand various physical and chemical changes and mechanical actions at high temperatures.

[0003] Current crushing devices for refractory brick raw materials, due to their inherent design features, are not convenient for rapid screening of the crushed materials during actual use. This can easily lead to the mixing of materials with different particle sizes, reducing the yield of finished products in subsequent processing, and also presents operational inconvenience.

[0027] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides a technical solution: a raw material crushing device for refractory brick production, including a frame 1, movable wheels 10 respectively set at the four corners of the lower end face of the frame 1, a crushing box 2 fixedly connected to the frame 1, a first crushing roller 31 set in the upper part of the inner cavity of the crushing box 2, and a second crushing roller 32 set parallel to the first crushing roller 31. Ball bearings are respectively set at both ends of the first crushing roller 31 and the second crushing roller 32. The ball bearings are fixedly connected to the inner wall of the crushing box 2. The ball bearings facilitate the connection of both ends of the first crushing roller 31 and the second crushing roller 32 to the crushing box 2, thereby facilitating the crushing of raw materials through the gap between the first crushing roller 31 and the second crushing roller 32.

[0028] Please refer to Figure 2 , Figure 3 and Figure 4A drive assembly for driving the first crushing roller 31 and the second crushing roller 32 includes a first drive gear 41 connected to the first crushing roller 31, a second drive gear 42 connected to the second crushing roller 32 and meshing with the first drive gear 41, and a drive motor 43 connected to the first drive gear 41. The output shaft of the drive motor 43 is connected to the first drive gear 41, and the mounting base of the drive motor 43 is connected to the crushing housing 2 by fixing screws. The output shaft of the drive motor 43 facilitates driving the first drive gear 41 to rotate. The first drive gear 41 and the second drive gear 42 respectively... The first crushing roller 31 and the second crushing roller 32 are connected by splines, which facilitates the connection of the first drive gear 41 to the first crushing roller 31 and the second drive gear 42 to the second crushing roller 32. When the drive motor 43 starts, the output shaft of the drive motor 43 rotates, which drives the first drive gear 41 to rotate. When the first drive gear 41 rotates, it drives the first crushing roller 31 to rotate, and the first drive gear 41 drives the second drive gear 42, which meshes with it, to rotate. This facilitates the second drive gear 42 to drive the second crushing roller 32 to rotate, thereby facilitating the crushing of the raw material by the first crushing roller 31 and the second crushing roller 32.

[0029] Please refer to Figure 2 , Figure 3 and Figure 4 The screening mechanism is located in the lower part of the crushing chamber 2. The screening mechanism includes a vibrating frame 5 installed in the inner cavity of the crushing chamber 2, a filter frame 6 slidably connected to the vibrating frame 5, and a vibrating motor 51 that passes through the crushing chamber 2 and connects to the vibrating frame 5. The crushing chamber 2 is provided with a groove that matches the vibrating frame 5, so that the vibrating frame 5 can be limited by the groove. The filter frame 6 is set along the height direction of the vibrating frame 5. There are at least three filter frames 6, and the aperture of the filter frame 6 decreases sequentially in the direction of material falling, so as to facilitate multi-stage screening of the crushed material through the filter frame 6.

[0030] Please refer to Figure 1 and Figure 2 In order to facilitate the removal of material remaining on the filter frame 6, the filter frame 6 is slidably connected to the crushing box 2. The front end of the crushing box 2 is provided with a sliding hole that matches the filter frame 6, so as to facilitate the removal of the filter frame 6 from the crushing box 2 and thus facilitate the removal of material remaining on the filter frame 6.

[0031] Working principle: When the drive motor 43 starts, its output shaft rotates, driving the first drive gear 41 to rotate. The rotation of the first drive gear 41 drives the first crushing roller 31 to rotate, and the first drive gear 41 drives the meshing second drive gear 42 to rotate. This facilitates the second drive gear 42 driving the second crushing roller 32 to rotate, thus facilitating the crushing of the raw material by the first and second crushing rollers 31 and 32. The vibration motor 51 drives the vibration frame 5 to vibrate, which in turn causes the filter frame 6 to vibrate. The material on the filter frame 6 is screened due to the vibration, effectively ensuring the efficiency of material screening by the filter frame 6.

[0032] The device designed above can basically meet the needs of improving the current crushing device for refractory brick raw materials. Due to its design characteristics, it is not convenient to quickly screen the crushed material after crushing it in actual use. This easily causes the mixing of materials with different particle sizes, which reduces the yield of finished bricks in the later processing. However, in order to further improve its function, the designer has made further improvements to the device.

[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
