Description

Technical Field

[0001] The present invention belongs to the technical field of fused quartz crushing devices, and specifically refers to a multi-stage impact type fused quartz crushing device. Background Art

[0002] In the field of quartz processing, the production process of fused quartz is high-temperature melting - cooling - crushing - screening. After the quartz sand is cleaned and dried, it is melted and sintered into a quartz ingot, and then the fused quartz is crushed and ground. Existing fused quartz crushing equipment usually uses impact crushers for operation. The crushing chambers of these impact crushers are usually designed relatively simply and have a single structure, and often cannot effectively process fused quartz raw materials with different particle sizes. In practical applications, the particle size differences of fused quartz raw materials are relatively large. Some crushers use a single crushing chamber to crush fused quartz with different particle sizes, resulting in certain processing difficulties caused by the size differences of raw material particles.

[0003] In the traditional impact crushing process of fused quartz, due to the mixing of fused quartz particles with different particle sizes in the crushing chamber, the smaller particle-sized fused quartz particles are often sandwiched in the gaps between the larger particles; during impact crushing, these smaller particles, due to their smooth surface or lower hardness, will have a buffering effect on the larger particles, reducing the impact force that the larger particles can withstand, thereby affecting the crushing effect; especially in the stone-on-stone crushing working condition, the presence of small particles will significantly reduce the crushing efficiency of large particles, resulting in the crusher being unable to achieve the ideal crushing effect and reducing the overall production efficiency. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention. Apparently, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the drawings. These are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention.

[0020] As Figures 1-6 shown, this embodiment includes a multi-stage crushing chamber 100 and an integrated material distributor 200. The integrated material distributor 200 is arranged in the multi-stage crushing chamber 100. The multi-stage crushing chamber 100 includes a primary crushing chamber 101 and a secondary crushing chamber 102. After the fused quartz raw material to be crushed enters the integrated material distributor 200, the integrated material distributor 200 rotates at a high speed and scatters the fused quartz raw material in all directions with a relatively high initial velocity. The high-speed moving fused quartz impacts the inner walls of the primary crushing chamber 101 and the secondary crushing chamber 102 and is shattered by the impact. At the same time, the particles will also collide with each other, further promoting the crushing of the raw material, thus completing the crushing of the fused quartz raw material.

[0021] In order to further optimize the crushing process and improve the efficiency, the crushing device proposed in this embodiment is provided with a plurality of screening gaps in the multi-stage crushing chamber structure for effective particle size diversion. The primary screening gap 105 is provided on the side surface of the primary crushing chamber 101 proposed in this embodiment. The primary screening gap 105 completely penetrates the side wall of the primary crushing chamber 101. The secondary screening gap 106 is provided on the side surface of the secondary crushing chamber 102. The secondary screening gap 106 completely penetrates the side wall of the secondary crushing chamber 102. At the same time, the width of the primary screening gap 105 is greater than the width of the secondary screening gap 106. The large-particle fused quartz is preferentially and effectively retained in the primary crushing chamber 101 for primary crushing, while the small particles will be screened out to avoid their buffering effect on the larger particles, ensuring that the larger particles can be fully impacted and shattered, thereby improving the crushing efficiency.

[0022] During use, the combined loading and feeding device 200 accelerates the fused silica raw materials, and then the fused silica raw materials enter the primary crushing chamber 101. These fused silica raw materials are mixed with fused silica particles of various sizes. The fused silica particles with a particle size smaller than the width of the primary screening gap 105 fly out of the primary crushing chamber 101 through the primary screening gap 105, while the fused silica particles with a particle size larger than the width of the primary screening gap 105 remain in the primary crushing chamber 101 for impact crushing. Since the primary screening gap 105 filters out the fused silica particles with a particle size smaller than its width from the primary crushing chamber 101, the accumulation of smaller-sized fused silica particles is avoided, the buffering effect of the smaller-sized fused silica particles is eliminated, and the impact force of the fused silica particles with a particle size larger than the width of the primary screening gap 105 hitting is ensured, thus ensuring the crushing effect.

[0023] Subsequently, the fused silica particles with a particle size smaller than the width of the primary screening gap 105 fly out of the primary screening gap 105 and then re-enter the combined loading and feeding device 200. The combined loading and feeding device 200 re-accelerates these fused silica particles with a particle size smaller than the width of the primary screening gap 105 and then enters the secondary crushing chamber 102 for secondary crushing. The secondary screening gap 106 is also provided on the secondary crushing chamber 102. The secondary screening gap 106 in the secondary crushing chamber 102 plays a role similar to that of the primary screening gap 105, screening and diverting the fused silica particles with a particle size smaller than the width of the primary screening gap 105 again. The fused silica particles with a particle size smaller than the width of the secondary screening gap 106 fly out through the secondary screening gap 106, and the fused silica particles with a particle size larger than the width of the secondary screening gap 106 are crushed in the secondary crushing chamber 102. Through multi-stage screening and diverting, the crushing device can efficiently process the fused silica raw materials, ensuring that the particles in each particle size range can be fully crushed, thereby improving the overall crushing effect.

[0024] In this embodiment, the multi-stage crushing chamber 100 includes a connecting rod 104. The primary crushing chamber 101 and the secondary crushing chamber 102 are fixedly connected through the connecting rod 104. The connecting rod 104 plays a role in stabilizing and supporting, ensuring the fixed relationship between the primary crushing chamber 101 and the secondary crushing chamber 102, and effectively preventing displacement or vibration between the two during operation, thus maintaining the stability and accuracy of the equipment.

[0025] There is a crushing chamber gap 103 between the primary crushing chamber 101 and the secondary crushing chamber 102. The crushing chamber gap 103 is configured to allow the molten quartz raw material to pass through. During actual use, the crushed molten quartz particles in the primary crushing chamber 101 fall into the secondary crushing chamber 102 for secondary crushing. At the same time, the molten quartz particles with a particle size smaller than the width of the primary screening gap 105 fly out from the primary screening gap 105, pass through the crushing chamber gap 103, and enter the secondary crushing chamber 102 for secondary crushing, effectively guiding them to the secondary crushing chamber 102 for further processing while avoiding the accumulation of small particles; the multi-stage crushing and screening mechanism ensures that molten quartz particles of different particle sizes can be processed in a timely and effective manner, avoiding the waste of impact force or uneven crushing caused by mixing the particles together.

[0026] In this embodiment, the combined material distributor 200 includes a primary material distribution cylinder 201 and a secondary material distribution cylinder 202. The primary material distribution cylinder 201 is arranged inside the primary crushing chamber 101 and is rotatably arranged relative to the primary crushing chamber 101. The secondary material distribution cylinder 202 is arranged inside the secondary crushing chamber 102 and is rotatably arranged relative to the secondary crushing chamber 102. During actual use, the molten quartz raw material is put into the primary material distribution cylinder 201. The primary material distribution cylinder 201 rotates at a high speed to throw the molten quartz particles of mixed sizes into the primary crushing chamber 101 for crushing. The crushed molten quartz particles fall into the secondary material distribution cylinder 202. At the same time, the molten quartz particles with a particle size smaller than the width of the primary screening gap 105 fly out from the primary screening gap 105, pass through the crushing chamber gap 103, and enter the secondary material distribution cylinder 202, where they are re-accelerated and then enter the secondary crushing chamber 102 for further crushing.

[0027] This embodiment also includes a multi-stage diversion sleeve 400. The multi-stage diversion sleeve 400 includes a primary guide sleeve 401 and a secondary guide sleeve 402. The primary guide sleeve 401 is arranged on the primary crushing chamber 101 and is configured to guide the molten quartz from the primary screening gap 105 through the crushing chamber gap 103 into the secondary material distribution cylinder 202. The secondary guide sleeve 402 is arranged on the secondary crushing chamber 102 and is configured to guide the molten quartz from the secondary screening gap 106 to the lower part of the secondary crushing chamber 102. By setting the primary guide sleeve 401 and the secondary guide sleeve 402, the molten quartz particles screened out from the primary screening gap 105 and the secondary screening gap 106 are diverted, enabling them to return to the multi-stage crushing chamber 100 and the combined material distributor 200, continuously diverting and integrating the molten quartz according to the particle size of the molten quartz particles during the crushing process, and improving the crushing efficiency.

[0028] By setting the primary material guiding sleeve 401 and the secondary material guiding sleeve 402, precise diversion and guiding of the fused quartz particles are carried out during the crushing process, ensuring that particles of different particle sizes can be sent into the appropriate crushing chambers according to their sizes; not only optimizing the flow path of the particles, but also avoiding the mutual influence between the particles, thus improving the overall crushing efficiency.

[0029] This embodiment also includes a power support base 300. The multi-stage crushing chamber 100 and the combined material distributor 200 are arranged on the power support base 300. The power support base 300 ensures the stability of the entire crushing system, can withstand various dynamic loads during the crushing process, avoids displacement or deformation of the equipment due to vibration or other factors, and ensures the efficient operation of the system.

[0030] A material distributing motor 301 is provided on the power support base 300; the combined material distributor 200 includes a linkage shaft 203. The primary material distributing cylinder 201 and the linkage shaft 203 are both connected to the linkage shaft 203. The linkage shaft 203 is arranged on the material distributing motor 301. When the material distributing motor 301 is started, the primary material distributing cylinder 201 and the secondary material distributing cylinder 202 are driven by the linkage shaft 203 to rotate at high speed, enabling the fused quartz raw material to quickly enter the crushing chamber and effectively break by hitting the inner wall of the crushing chamber at high speed.

[0031] In this embodiment, a material receiving ring 302 is provided on the power support base 300. The material receiving ring 302 is located directly below the multi-stage crushing chamber 100. The fused quartz particles during the crushing process can smoothly flow to the lower collection area, avoiding waste or blockage problems caused by untimely or uneven dropping of the particles during the crushing process.

[0032] An outlet 303 is provided on the material receiving ring 302 for discharging the crushed fused quartz particles and sending them to the next process or for storage. The design of the outlet 303 ensures the continuous flow of the material. Through the reasonably designed outlet 303, the system can efficiently discharge the crushed fused quartz particles, ensuring the efficient operation of the equipment.

[0033] In this embodiment, a rotating discharge wheel 304 is provided on the material receiving ring 302. The rotating discharge wheel 304 is rotatably arranged relative to the material receiving ring 302. Through the operation of the rotating discharge wheel 304, the fused quartz particles collected on the material receiving ring 302 can be effectively driven and guided to the outlet 303. Through the cooperation of the rotating discharge wheel 304 and the material receiving ring 302, the fused quartz is not easily accumulated or blocked during the discharge process, ensuring the smooth flow of the fused quartz after crushing and avoiding the occurrence of stagnation and material accumulation phenomena.

[0034] The rotating discharge wheel 304 is provided with discharge bars 305, which are used to increase the friction between the rotating discharge wheel 304 and the fused silica particles, and help the rotating discharge wheel 304 to carry the fused silica particles from the material receiving ring 302 to the discharge outlet during rotation, ensuring that the material can flow out of the material receiving ring 302 quickly and evenly.

[0035] In this embodiment, the power support base 300 is provided with a crushing chamber support 306. The primary crushing chamber 101 and the secondary crushing chamber 102 are arranged on the crushing chamber support 306. The crushing chamber support 306 is provided with a crushing motor 307, which is configured to drive the primary crushing chamber 101 and the secondary crushing chamber 102 to rotate. The rotation directions of the primary crushing chamber 101 and the secondary crushing chamber 102 are opposite to the rotation direction of the combined distributor 200, increasing the relative speed between the fused silica discharged by the combined distributor 200 and the multi-stage crushing chamber 100. The fused silica particles are subjected to more intense collision and friction in the crushing chamber, which greatly improves the crushing efficiency of the fused silica particles, enables particles of different particle sizes to collide with each other better, and are more effectively crushed into finer particles.

[0036] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.

[0037] The above describes the present invention and its implementation manners. This description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. All in all, if those of ordinary skill in the art are inspired by it and design similar structural modes and embodiments without creative efforts without departing from the purpose of the present invention, they shall fall within the protection scope of the present invention.
