Description

Technical Field

[0001] The invention relates to the technical field of glass fiber production, in particular to a multi-stage raw material crushing device used in glass fiber production. Background Art

[0002] Glass fiber is an inorganic non-metallic material with excellent performance and comes in many varieties. Its advantages are good insulation, strong heat resistance, good corrosion resistance and high mechanical strength, but its disadvantages are brittleness and poor wear resistance. Many high-quality kaolin ores can be directly used in the glass fiber industry after grinding. Nano-grade kaolin is required in the production process of glass fiber. When producing nano-grade kaolin, the raw materials need to be purified and impurity-removed.

[0003] Publication No. CN117380332B discloses a kaolin crushing device for glass fiber production. Two crushing rollers crush the raw material, and the crushed raw material is collected in a collection chamber below the two crushing rollers. The filter holes on the rotating drum filter the raw material. Raw material with qualified particle size falls through the filter holes and is discharged from the discharge port to the processing box. Raw material with unqualified particle size continues to be collected in the collection chamber below the crushing rollers until it is dropped again from above the two crushing rollers. In this way, the raw material with unqualified particle size is continuously crushed until it meets the requirements, thereby improving the crushing effect of the raw material, increasing the utilization rate of the raw material, and thus saving raw material. As the rotating drum rotates, the crushed raw material in the collection chamber is in a flowing state, thereby improving the filtering effect. However, this patent still has the following problems in actual use:

[0004] Although the kaolin crushing device for glass fiber production can use crushing rollers to crush raw materials, the crushed raw materials are collected in the collection chamber below the two crushing rollers, and the filter holes on the rotating cylinder filter the raw materials, and raw materials with qualified particle size fall from the filter holes and are discharged from the discharging port to the processing box, but since the spacing between the crushing rollers is fixed, the particle size of the crushed kaolin is constant. When the hardness and particle size of the kaolin change, it is easy to cause damage to the crushing rollers when the kaolin is crushed by using fixed crushing rollers. At the same time, the hard kaolin will be stuck between the crushing rollers, thereby affecting the crushing effect of the crushing rollers.

[0005] Therefore, a multi-stage crushing device for raw materials used in glass fiber production is proposed to solve the above-mentioned problems. Summary of the Invention

[0006] The purpose of the present invention is to provide a multi-stage crushing device for raw materials used in glass fiber production, so as to solve the problem raised in the above background technology that the spacing between the crushing rollers is fixed, resulting in a certain particle size of the crushed kaolin.

[0041] Working principle: Before using this multi-stage crushing device for raw materials used in glass fiber production, it is necessary to first check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 11 As shown, first, the conveying motor 203 is used to drive the conveying rotating rod 204 to rotate, so that the conveying rotating rod 204 drives the conveying spiral blade 205 to rotate. Through the structural characteristics of the conveying spiral blade 205, the raw material can be conveyed.

[0043] Finally, by pressing the locking ring 134 and utilizing the meshing connection between the locking gear 130 and the first locking rack 131 and the second locking rack 132, the relative movement of the first locking rack 131 and the second locking rack 132 can be achieved. When the second locking rack 132 is engaged with the meshing gear ring 105, the filter cylinder 123 can be fixed. At the same time, the first locking rack 131 is separated from the engaging ring 107, and the first rotating disk 108 and the crushing driven gear 104 can be rotated, thereby adjusting the position between the first crushing roller 113 and the second crushing roller 114. Since the diameters of the first crushing roller 113 and the second crushing roller 114 are different, the crushing roller 113 and the second crushing roller 114 are different. The particle sizes of the kaolin raw materials are different. The large-particle size kaolin raw materials are crushed step by step, thereby improving the crushing effect of the kaolin raw materials. The elastic force of the protective spring 116 inside the protective chute 115 can be used to realize the sliding of the crushing block 117, thereby protecting the crushing block 117 and improving the service life of the crushing block 117. The outer surface of the filter cylinder 123 can be cleaned by the cleaning brush 125, thereby improving the filtering effect of the filter cylinder 123.
