Technical Field

[0001] This utility model relates to the field of sand making machine technology, and in particular to a dust collector for an impact crusher sand making machine. Background Technology

[0002] The impact crusher, also known as a sand making machine, is a high-energy, low-consumption impact crusher with internationally advanced technology. Its performance plays an irreplaceable role among various ore fine crushing equipment, making it the most effective, practical, and reliable stone crushing machine. Sand making machines are suitable for crushing and shaping soft, medium-hard, and extremely hard materials, and are widely used in various ores, cement, refractory materials, bauxite clinker, corundum, glass raw materials, manufactured building sand, stone, and various metallurgical slags. They are particularly effective for high-hardness, ultra-hard, and abrasion-resistant materials such as silicon carbide, corundum, sintered bauxite, and silica sand, offering higher output and efficiency than other types of crushers. In the engineering field, sand making machines are ideal production equipment for manufactured sand, subbase materials, asphalt concrete, and cement concrete aggregates. In the mining industry, sand making machines are widely used in the pre-grinding process, producing large quantities of fine ore and reducing the high-cost grinding load.

[0003] For example, Chinese utility model patent (CN219291600U) discloses a dust collector for an impact crusher and sand making machine, which states: "It effectively solves the problem of dust flying during crushing caused by sand and gravel directly entering the machine for crushing without dust removal equipment in the current impact crusher and sand making machine on the market. By adding dust removal equipment at the sand and gravel inlet, the dust phenomenon during the sand and gravel crushing process is effectively avoided. At the same time, the addition of guide parts and shock absorbers ensures that the sand and gravel enter the equipment while avoiding the ejection damage to the dust removal equipment caused by the crushing of sand and gravel. Moreover, by placing it directly at the sand inlet, the equipment achieves versatility and reduces production costs."

[0023] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Example

[0024] Please refer to Figures 1-4 A dust collector for an impact crusher and sand making machine, comprising: The fixed frame assembly 1 has a flow guide 2 at its upper end for buffering and guiding the flow. The flow guide 2 can guide the flow direction of sand and gravel and avoid the impact of sand and gravel on the fixed frame assembly 1. The inner side of the fixed frame assembly 1 is equipped with a dust suppression pipe assembly 3 for spraying dust suppression. The sprayed water mist is fully mixed with the dust-laden airflow to achieve a high-efficiency dust suppression effect. Specifically, the fixed frame assembly 1 includes a top plate 5 and a bottom plate 4 arranged parallel to each other. Multiple connecting fasteners 6 are arranged in a circular array between the top plate 5 and the bottom plate 4. The upper ends of the multiple connecting fasteners 6 are fixedly connected to the top plate 5, and the lower ends of the multiple connecting fasteners 6 are fixedly connected to the bottom plate 4. The connecting fasteners 6 not only connect the top plate 5 and the bottom plate 4, but also provide positioning and support for the installation of other components. A sealing plate 10 is also provided between the top plate 5 and the bottom plate 4. Multiple sealing plates 10 are arranged in a circular array, forming a circular enclosure. The connecting fasteners 6 are located inside the circular enclosure, and the two ends of the sealing plate 10 are detachably and fixedly connected to two adjacent connecting fasteners 6. This effectively prevents airflow and dust from leaking out of the fixed frame assembly 1.

[0025] Specifically, the guide frame 2 is funnel-shaped, with its lower end extending to the inside of the fixed frame assembly 1. The lower end of the guide frame 2 is located between the bottom plate 4 and the top plate 5, ensuring that the sand and gravel can smoothly enter the impact crusher.

[0026] Specifically, the dust suppression pipe assembly 3 includes a diversion pipe 7, which is located between the bottom plate 4 and the top plate 5. The diversion pipe 7 is fastened to the connecting buckle 6, which facilitates the installation and disassembly of the diversion pipe 7. Multiple dust suppression nozzles 8 are arranged in a ring array on the inner side of the diversion pipe 7. The multiple dust suppression nozzles 8 can evenly spray out fine water mist, which can fully contact the dust-laden airflow to achieve efficient dust suppression. A water inlet pipe 9 is fixedly connected to the outer side of the diversion pipe 7. The water inlet pipe 9 extends to the outer side of the fixing frame assembly 1 for connecting to an external water source to provide a continuous water supply for the dust suppression nozzles 8.

[0027] Furthermore, a buffer and a fixing component are provided between the top plate 5 and the guide frame 2. The buffer is used to reduce impact and dampen vibration to ensure stable operation of the equipment. The fixing component is used for positioning and installing the guide frame 2 and limiting its movement to prevent displacement of the guide frame 2 during use. Example

[0028] The dust collector for the impact crusher sand making machine provided in Example 1 has been further optimized, specifically, as follows: Figure 5 As shown, a detachable annular sealing plate 15 is also provided between the flow guide 2 and the base plate 4. The upper end of the annular sealing plate 15 is sleeved on the outer side of the lower end of the flow guide 2, and the lower end of the annular sealing plate 15 is in contact with the inner side of the base plate 4. The annular sealing plate 15 is used to seal the gap between the flow guide 2 and the base plate 4, and can further seal the gap between the flow guide 2 and the base plate 4 to prevent dust and airflow from leaking out from the gap. Corresponding windows are opened on the annular sealing plate 15 at the positions corresponding to the dust suppression nozzle 8 to ensure that the water mist sprayed by the dust suppression nozzle 8 can smoothly enter the dust-laden airflow without affecting the dust suppression effect.

[0029] The above structural design effectively improves the sealing performance of the dust collector, reduces the leakage of dust and airflow, and further enhances the dust removal effect. At the same time, the detachable design also facilitates the maintenance and replacement of the annular sealing plate 15. Example

[0030] The dust collector for the impact crusher sand making machine provided in Example 1 has been further optimized, specifically, as follows: Figure 4 As shown, the buffer includes a first sealing hose 11 and a second sealing hose 12. The first sealing hose 11 is fixedly connected to the bottom of the flow guide frame 2, and the second sealing hose 12 is fixedly connected to the top of the top plate 5. There are two second sealing hoses 12. The first sealing hose 11 is located between the two second sealing hoses 12. Both the first sealing hose 11 and the second sealing hose 12 are hollow. The hollow structure can deform to a certain extent when subjected to impact, thereby absorbing and dispersing the impact force and reducing the impact of vibration on the equipment.

[0031] Through the above structural design, the buffer can effectively reduce the impact on the flow guide frame 2 and the top plate 5, protect the equipment from damage caused by excessive vibration, extend the service life of the equipment, and ensure the stable operation of the equipment. Example

[0032] The dust collector for the impact crusher sand making machine provided in Example 1 has been further optimized, specifically, as follows: Figure 4 As shown, the fasteners include a limiting buckle 13 and a fixing bolt 14. The upper end of the limiting buckle 13 is fastened to the guide frame 2, and the lower end of the limiting buckle 13 is arc-shaped. The bottom of the limiting buckle 13 fits against the top of the top plate 5, which can better adapt to the shape of the guide frame 2 and the top plate 5, providing stable support and limiting. The lower end of the fixing bolt 14 is plugged into the guide frame 2, the upper end of the limiting buckle 13, and the lower end of the limiting buckle 13, which facilitates installation and disassembly. The lower end of the fixing bolt 14 is threaded to the top plate 5. The threaded connection ensures that the connection between the fixing bolt 14 and the top plate 5 is firm and reliable.

[0033] Through the above structural design, the fixing component can accurately position the flow guide 2 and effectively restrict the movement of the flow guide 2, ensuring the stability of the flow guide 2 during use, thereby improving the working efficiency and reliability of the entire dust collector.
