[0002] In the current field of monocrystalline silicon production technology, monocrystalline silicon usually refers to a substance in which silicon atoms are arranged in a certain form. Silicon is the most common and widely used semiconductor material. When molten elemental silicon solidifies, silicon atoms are arranged in a diamond lattice to form crystal nuclei. The crystal nuclei grow into grains with the same crystal orientation, forming monocrystalline silicon. During its processing, loading and unloading are required. This process is prone to generating dust, causing environmental pollution and also causing pollution during the crystal pulling process. Therefore, dust removal equipment is required.

[0042] Please see Figure 1-3 This utility model provides a technical solution: a dust removal device for easy solid waste collection, including an adjustment mechanism 1 and a dust removal mechanism 2, which includes a dust removal box 21. The dust removal box 21 is disposed on one side of the adjustment mechanism 1. The dust removal box 21 has a separation chamber 211 and an air guide chamber 212 inside. An air intake fan 23 is fixedly installed on one outer wall of the dust removal box 21, and an exhaust fan 24 is fixedly installed on the other outer wall. The air intake fan 23 is connected to the separation chamber 211, and the exhaust fan 24 is connected to the air guide chamber 212. A separation mechanism 3 is used to separate dust. The separation mechanism 3 is installed on the dust removal box 21 and includes dust removal rollers 31. Multiple dust removal rollers 31 are rotatably installed in the dust removal box 21. The multiple dust removal rollers 31 are arranged longitudinally in the separation chamber 211, and a connecting cylinder 312 is installed at the end of the dust removal rollers 31. The multiple dust removal rollers 31 are connected to the air guide chamber 212 through the connecting cylinder 312.

[0043] In this process, the air containing dust is transported to the separation chamber 211 by the intake fan 23. The air is filtered by multiple dust removal rollers 31. The filtered air enters the air guide chamber 212 through the connecting cylinder 312, and the exhaust fan 24 discharges the filtered air.

[0044] Multiple dust collector rollers 31 have bevel gears 311 fixedly installed at their ends after passing through the dust collector box 21. A geared motor 32 is fixedly installed on the outer wall of the dust collector box 21. A rotating shaft 321 is fixedly installed at the output end of the geared motor 32. The rotating shaft 321 is rotatably installed on the outer wall of the dust collector box 21. Multiple bevel gears 322 that mesh with bevel gears 311 are rotatably fixedly installed on the rotating shaft 321, and the multiple bevel gears 322 correspond one-to-one with the multiple bevel gears 311.

[0045] Among them, the second gear motor 32 drives the rotating shaft 321 to rotate, thereby driving multiple bevel gears 322 to rotate, thereby using gear transmission to drive multiple dust removal rollers 31 to rotate, so that the dust removal rollers 31 have more contact with the air and facilitate the dust on the dust removal rollers 31 to fall off.

[0046] An air guide pipe 331 is fixedly installed inside the air guide chamber 212. Multiple nozzles 332 are fixedly installed on the air guide pipe 331. Each nozzle 332 is directly facing the corresponding connecting cylinder 312. An air pump 33 is fixedly installed on the upper surface of the dust collection box 21. The air pump 33 is connected to the air guide pipe 331 through a pipe.

[0047] Furthermore, the air pump 33 can be connected to a compressed air source at its air inlet. The air pump 33 delivers air to the air guide pipe 331, which sprays it out through multiple nozzles 332 and then sprays it onto the dust removal roller 31 through the connecting cylinder 312, causing the dust on its outer surface to fall off, thus improving the cleaning efficiency.

[0048] The bottom of the dust collector 21 is provided with multiple support legs 22. Each support leg 22 is fixedly installed with a support spring 221. One end of the support spring 221 is fixedly connected to the support leg 22, and the other end is fixedly connected to the dust collector 21. Pads 215 are fixedly installed on both outer walls of the dust collector 21. A geared motor 25 is fixedly installed on the outer wall of the two support legs 22. An eccentric block 251 is fixedly installed at the output end of the geared motor 25.

[0049] In addition, the geared motor 25 drives the eccentric block 251 to rotate, and the eccentric block 251 lifts the pad block 215, thereby lifting the dust collection box 21. The support spring 221 uses its own elasticity to reset, causing the dust collection box 21 to vibrate longitudinally, causing the dust on the inner wall of the dust collection box 21 to fall off. At the same time, the two geared motors 25 are controlled by the synchronous controller to make the eccentric block 251 rotate synchronously. The bottom end of the support leg 22 can be fixed to the ground through pads and bolts, thereby improving the stability of the support leg 22.

[0050] The bottom of the dust collector 21 is provided with a conical discharge port 213. A discharge pipe 214 connected to the discharge port 213 is fixedly installed at the bottom of the discharge port 213. A collection box 26 is provided at the lower end of the dust collector 21. A feed inlet 261 that is slidably connected to the discharge pipe 214 is provided on the collection box 26.

[0051] In addition, the dust inside the dust collector 21 is discharged through the discharge port 213 and falls into the collection box 26 through the discharge pipe 214 for centralized collection and treatment. At the same time, the dust collector 21 can be lifted by the eccentric block 251 to facilitate the removal of the collection box 26.

[0052] The adjustment mechanism 1 includes a gantry frame 11, which is located on one side of the dust collection box 21. An adjustment screw 12 is rotatably mounted on the gantry frame 11, and a sliding nut 121 is threaded onto the adjustment screw 12. A drive motor 13 is fixedly mounted on the gantry frame 11, and the drive motor 13 is connected to the adjustment screw 12. A guide pipe 14 is fixedly mounted on the lower end of the sliding nut 121. The guide pipe 14 is connected to the air intake end of the air intake fan 23 through a flexible hose. Multiple air intake heads 141 are fixedly mounted on the lower surface of the guide pipe 14.

[0053] Specifically, the drive motor 13 drives the adjusting screw 12 to rotate, which in turn drives the sliding screw nut 121 to move laterally, which in turn drives the guide tube 14 to move laterally. The air intake fan 23 provides suction, and multiple air intake heads 141 draw in air containing dust, which can remove dust from different equipment and has a wider range of applications.

[0054] The working principle and usage process of this utility model are as follows: After installation, a programmable controller can be installed on the dust collection box 21. The programmable controller controls the device, drives the motor 13 to rotate the adjusting screw 12, thereby causing the sliding screw nut 121 to move laterally, which in turn causes the guide tube 14 to move laterally. The intake fan 23 provides suction, and air containing dust is drawn in by multiple air intake heads 141. The dust-laden air is transported to the separation chamber 211, where it is filtered by multiple dust collection rollers 31. The reduction motor 32 drives the rotating shaft 321 to rotate, which in turn drives multiple bevel gears 322 to rotate. This gear transmission drives the multiple dust collection rollers 31 to rotate, making the dust collection rollers 31 more in contact with the air and facilitating the removal of dust from the dust collection rollers 31. The filtered air is then discharged through the connecting cylinder 31. 2. The air enters the air guide chamber 212. The exhaust fan 24 discharges the filtered air. The air pump 33 can be connected to a compressed air source. The air pump 33 delivers air to the air guide pipe 331 and sprays it out through multiple nozzles 332. The air is then sprayed onto the dust removal roller 31 through the connecting cylinder 312, causing the dust on its outer surface to fall off, resulting in higher cleaning efficiency. The geared motor 25 drives the eccentric block 251 to rotate. The eccentric block 251 lifts the pad block 215, thereby lifting the dust removal box 21. The support spring 221 uses its own elasticity to reset, causing the dust removal box 21 to vibrate longitudinally, causing the dust on the inner wall of the dust removal box 21 to fall off. The dust inside the dust removal box 21 is discharged through the discharge port 213 and falls into the collection box 26 through the discharge pipe 214 for centralized collection and treatment. At the same time, the eccentric block 251 can be used to lift the dust removal box 21, making it easier to remove the collection box 26.

[0055] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
