Description

Technical Field

[0001] The utility model relates to the technical field of dispersing and classifying, in particular to a wear-resistant and impact-resistant dispersing and classifying machine. Background Art

[0002] The disintegrator classifier is a kind of equipment widely used in many industrial fields, especially when it is necessary to process materials of various particle sizes and compositions. Its importance is more prominent. This equipment combines the functions of disintegration and classification, and can effectively disintegrate and separate the materials into different particle size levels. The disintegrator is responsible for crushing and disintegrating the materials to make their particle size more uniform, laying the foundation for subsequent classification operations. The classification mechanism separates the materials according to their particle size, ensuring that materials of different particle sizes can be accurately separated to meet different production needs.

[0003] During the feeding process of the existing scattering and classifying machine, especially when the material flow rate is large or the material particle size is uneven, when the material enters the scattering roller in a free fall state, due to the superposition effect of speed and mass, a large impact force will be generated on the roller. If this continues for a long time, it may cause the surface of the scattering roller to wear faster, and even cause deformation or breakage, shortening its service life.

[0004] For example, a scattering and grading device for producing cement is disclosed with announcement number CN218796400U. In this patent, a buffer structure is provided to protect the scattering roller from the impact of materials. When the material enters the processing box and contacts the scattering roller, especially when the material flow rate is large or the material particles are large, the material may have a direct and strong impact on the scattering roller. This impact may not only cause damage to the scattering roller and shorten its service life, but also affect the scattering effect and even threaten the stability and safety of the entire equipment.

[0005] Therefore, it is necessary to invent a wear-resistant and impact-resistant breaking and classifying machine to solve the above problems. Utility Model Content

[0012] Preferably, a small pulley is fixedly connected to the output end of the No. 1 gear, a large pulley is arranged directly below the small pulley, a belt is tensioned on the small pulley and the large pulley, a driving motor is arranged on the front side of the small pulley, the small pulley is connected to the output end of the driving motor, and the power of the driving motor is transmitted to the breaking up roller through a belt transmission system composed of a small pulley, a large pulley and a belt.

At the same time, filters with different apertures can achieve graded filtration of materials of different particle sizes.

[0014] Preferably, one end of the No. 1 filter passes through the grading box and extends to the outside, and a No. 1 discharge port is opened at the position where the No. 1 filter passes through the grading box. One end of the No. 2 filter passes through the grading box and extends to the outside, and a No. 2 discharge port is opened at the position where the No. 2 filter passes through the grading box.

It can allow larger particles of material to pass through, while intercepting and separating larger impurities or particles. Filter plate No. 2 is used for further fine filtration. It can intercept and separate smaller impurities or particles. By combining the use of two filter plates with different apertures, the effect of graded filtration can be achieved, and the vibration motors at the bottom of filter plates No. 1 and No. 2 can provide strong vibration force to further promote the separation and filtration of materials. The vibration generated by the vibration motor can make the material form continuous jumping and rolling on filter plates No. 1 and No. 2, thereby effectively separating materials of different particle sizes. This vibration effect can not only improve the grading efficiency, but also reduce the clogging and accumulation of materials on filter plates No. 1 and No. 2. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] By setting two buffer plates 3, when the material enters the scattering box 1, the buffer plate 3 can produce a certain swing under the impact of the material, thereby alleviating the impact force of the material on the scattering roller 11. At the same time, the buffer spring 4 at the bottom of the buffer plate 3 can absorb and disperse the remaining impact force, further protecting the scattering roller 11 from damage. Through the synchronous rotation of the two scattering rollers 11, the material can be effectively scattered and mixed, which provides convenience for subsequent processing or grading.

[0031] The No. 1 filter 14 and the No. 2 filter 17 are designed in an inclined state, the aperture of the No. 1 filter 14 is larger than the aperture of the No. 2 filter 17, the No. 1 filter 14 is arranged directly above the No. 2 filter 17, the No. 1 filter 14, the No. 2 filter 17 and the inner wall of the grading box 13 are slidably connected, one end of the No. 1 filter 14 passes through the grading box 13 and extends to the outside, a No. 1 discharge port 15 is provided at the position where the No. 1 filter 14 passes through the grading box 13, one end of the No. 2 filter 17 passes through the grading box 13 and extends to the outside, and a No. 2 discharge port 18 is provided at the position where the No. 2 filter 17 passes through the grading box 13.

This grading design can achieve accurate separation of materials and improve the purity and quality of products. The inclined state design of filter screen No. 14 and filter screen No. 2 17 is conducive to the natural flow and separation of materials on filter screen No. 14 and filter screen No. 2 17, so that the materials can slide smoothly along filter screen No. 14 and filter screen No. 2 17 under the action of gravity to achieve effective separation. At the same time, the design of discharge port No. 1 15 and discharge port No. 2 18 makes it convenient for materials of different particle sizes to be discharged from different positions.

[0033] Working principle of this utility model:

[0034] Refer to the instruction manual Figure 1-3 When using the utility model, first pour the material to be broken up and graded into the inside of the breaking box 1 through the feed hopper 2. When the material falls into the feed hopper 2, it will encounter two buffer plates 3 hinged to the inner wall of the feed hopper 2. The two buffer plates 3 will swing to a certain extent under the impact of the material. At the same time, the buffer spring 4 at the bottom will also absorb and disperse the impact force, thereby effectively reducing the impact of the material on the breaking roller 11. After buffering, the material falls between the two parallel breaking rollers 11 inside the breaking box 1. The two breaking rollers 11 rotate at the same speed and direction through the driving motor 5, the small pulley 6, the large pulley 7, the belt 8, the first gear 9 and the second gear 10 to break up and mix the material.

[0035] Refer to the instruction manual Figure 4-7When the utility model is used, the dispersed material enters the grading box 13 through the discharge hopper 12, and the coarser material particles will be intercepted by the No. 1 filter screen 14, while the finer material particles can pass through the No. 1 filter screen 14 and continue to be filtered by the No. 2 filter screen 17. When the No. 1 filter screen 14 and the No. 2 filter screen 17 are filtering the material, the No. 1 vibration motor 16 and the No. 2 vibration motor 19 will generate vibration force, so that the material can flow and separate more quickly on the No. 1 filter screen 14 and the No. 2 filter screen 17 to prevent blockage and accumulation. At the same time, the material remaining on the No. 1 filter screen 14 will be discharged through the No. 1 discharge port 15, and the material remaining on the No. 2 filter screen 17 will be discharged through the No. 2 discharge port 18, thereby achieving the dispersion and grading of the material.
