TECHNICAL FIELD

[0001] The utility model relates to the technical field of fine crusher, concretely is a kiln tail fuel fine crusher. BACKGROUND

[0002] The existing kiln tail fuel fine crusher usually adopts the fixed structure of the crushing roller group to realize the fine crushing of the material, and the material is crushed by compression and shearing effect between the crushing rollers. In the traditional technology, the roller group is generally composed of two or more rollers, and the roller body is supported by bearings and rotated by a driving device. After the material enters the crushing cavity, the roller body performs fine crushing treatment on the material through extrusion and shearing effect with the material. The existing equipment is usually equipped with a screen to screen out fine materials, but the process of material entering the roller group and the discharge mode of the material are relatively single, and the adjustment and cleaning of the equipment are not convenient.

[0003] Corresponding beneficial effects, reveal the defects of the traditional technical scheme:

[0004] The crushing roller group structure of the traditional kiln tail fuel fine crusher generally adopts symmetrically arranged roller bodies with fixed gaps, which cannot be flexibly adjusted according to the different characteristics of the material. When processing large pieces of material, the traditional scheme often leads to unsatisfactory crushing effect due to the too large gap, and the existing equipment often relies on single extrusion effect and lacks effective shearing force. Therefore, the traditional equipment has low efficiency when crushing large pieces of material, and cannot accurately control the crushing effect.

[0005] In the traditional equipment, the material screening method is relatively single, the screen is easy to block during use, and it is difficult to clean in real time. During the crushing process, fine materials and large materials cannot be separated in time, which affects the fine crushing efficiency. In addition, the equipment maintenance and cleaning in the traditional scheme are relatively complicated, many parts need to be disassembled, which leads to long downtime, increases the complexity and cost of maintenance.

[0006] Therefore, the existing problems are studied and improved, and a kiln tail fuel fine crusher is provided to solve the existing problems, aiming to solve the problems and improve the practical value through the technology. INVENTION CONTENTS

[0029] Embodiment 1

[0030] In this embodiment, the kiln tail fuel fine crusher is an industrial-scale fuel processing equipment, which is suitable for fine crushing of kiln tail materials.

[0031] In this embodiment, when the crushing roller group 300 rotates, the eccentric effect is generated by the combined movement of the roller shaft 310 and the roller body 320, which makes the surface of the crushing bar 330 gradually mesh with the convex rib 410 and the grinding groove 420, further extruding and shearing the large block material. In this way, when the material enters between the crushing roller group 300 and the crushing guide plate 400, the material is uniformly and effectively crushed, meeting the requirement of fine crushing of the kiln tail fuel.

[0032] During the crushing process, the filter holes on the screen bucket 220 effectively screen the fine crushed material, thereby avoiding the accumulation of excessively fine material. The fine crushed material is filtered out in time through the filter holes on the screen bucket 220, ensuring uniform particle size of the fine crushed material and high crushing efficiency.

[0033] During maintenance, the feeding box 210 is driven to deflect by the opening and closing rod 212, quickly opening the top surface of the crusher box 200, so that the screen bucket 220 can be quickly disassembled, facilitating cleaning and inspection of the inside of the equipment. This design improves the operability and maintenance efficiency of the equipment, reducing downtime.

[0034] The flywheel connected at the end of the crushing roller group 300 effectively balances the moment of inertia, avoiding vibration caused by unbalanced rotation and improving the stability and service life of the equipment.

[0035] Embodiment 2

[0036] This embodiment uses a kiln tail fuel fine crusher to process kiln tail waste, which is suitable for occasions that require efficient screening.

[0037] In this embodiment, the eccentric design of the crushing roller group 300 and the crushing guide plate 400 makes the distance between the crushing roller group 300 and the crushing guide plate 400 gradually decrease. During rotation, it can efficiently extrude and crush larger materials. At the same time, the meshing action between the crushing bar 330 and the convex rib 410 and the grinding groove 420 can further shear the material, ensuring the fine crushing effect.

[0038] The filter holes provided on the surface of the screen bucket 220 allow the fine crushed material to be filtered out in time, ensuring accurate control of the particle size of the material and avoiding the accumulation of excessive fine crushed material, achieving the ideal fine crushing effect.

[0039] During maintenance, the feeding box 210 is driven to deflect by the opening and closing rod 212, achieving the opening of the top surface of the crusher box 200, so that the operator can conveniently clean and maintain the equipment, improving the maintenance efficiency and safety of the equipment.

[0040] The flywheel connected at the end of the crushing roller group 300 helps to balance the moment of inertia of the equipment, reducing the unbalanced force during rotation, reducing the vibration and wear of the equipment, and prolonging the service life.
