Detailed Implementation
[0022] The following embodiments are further explanations and supplements to the present invention and do not constitute any limitation on the present invention.
[0023] Please see Figure 1The grinding device 100 provided by this utility model includes a chamber 10, a grinding platform 20, a dust collection hood 30, and an exhaust fan 40.
[0024] The silo body 10 is provided with a dust outlet 11; the grinding platform 20 is horizontally located inside the silo body 10 for grinding materials; the dust collection hood 30 is located outside the silo body 10, on the side of the silo body 10 and / or below the grinding platform 20, for collecting dust, and the dust collection hood 30 is provided with a connecting port 31 that connects to the dust outlet 11 and / or the first through hole 21; the exhaust fan 40 is connected to the connecting port 31 for extracting the dust generated by the grinding platform 20 grinding the materials.
[0025] When grinding materials, the grinding device 100 places the materials on the grinding platform 20. The dust generated during the grinding process is collected in the dust collection hood 30 through the dust outlet 11 and / or the first through hole 21 under the suction force of the exhaust fan 40, and is finally extracted by the exhaust fan 40, thereby achieving dust collection to protect the environment and prevent the dust from being inhaled by the operators and affecting their health.
[0026] Specifically, the material in this embodiment is an aluminum template. Understandably, in one grinding method, a grinding wheel can be installed inside the chamber 10, and a motor drives the grinding wheel to rotate, thus grinding the surface of the aluminum template. In another embodiment, an opening can be provided on one side of the chamber 10, allowing the operator to stand at the opening and hold a grinding tool to grind the aluminum template.
[0027] In the dust collection hood 30, to achieve better dust collection, the dust outlet 11 is located above the grinding platform 20. The dust collection hood 30 includes an air outlet hood 32 and a dust collection bin 33 with interconnected inner cavities. The air outlet hood 32 is located to the side of the dust outlet 11 and above the grinding platform 20, while the dust collection bin 33 is located below the grinding platform 20. The dust collection bin 33 and the grinding platform 20 have a dust discharge port 331 on the opposite side. The air outlet hood 32 or the dust collection bin 33 has a connecting port 31. Thus, the fine dust generated during the grinding process gradually enters the air outlet hood 32 through the dust outlet 11 under the suction of the exhaust fan 40 and is extracted by the exhaust fan 40. At the same time, some large particles of residue fall into the dust collection bin 33 through the first through hole 21 of the grinding platform 20 by their own gravity, and are finally collected or discharged by the dust collection bin 33. In this way, the dust generated during the polishing process can be collected, that is, the fine dust and large-particle residue can be collected separately.
[0028] The connecting port 31 can be set in the air outlet hood 32 or the ash collection bin 33. Since the inner cavities of the air outlet hood 32 and the ash collection bin 33 are interconnected, smaller dust particles can be extracted under the suction force of the exhaust fan 40.
[0029] Specifically, in order to achieve better dust collection, the dust collection bin 33 in this embodiment is provided with a connecting port 31. Thus, smaller dust particles initially move towards the exhaust hood 32 under the suction force of the exhaust fan 40 and flow through the connecting port 31 to the exhaust fan 40 for extraction. Further, larger dust particles and smaller dust particles that are missed and do not flow to the exhaust hood 32 fall through the first through hole 21 and are extracted again by the exhaust fan 40 provided on the dust collection bin 33. At the same time, since the exhaust fan 40 is provided on the dust collection bin 33, the air force is directly generated inside the dust collection bin 33, which can suck out some of the larger dust particles.
[0030] Understandably, since the dust collection bin 33 and the grinding platform 20 are provided with a dust discharge port 331 on the opposite side, in order to facilitate the collection of large-diameter residue, the diameter of the dust collection bin 33 gradually decreases from the grinding platform 20 toward the dust discharge port 331. That is, the dust collection bin 33 is set in the shape of a funnel. As the residue falls into the dust collection bin 33, the residue gradually slides toward the dust discharge port 331 by its own gravity, avoiding adhesion to the side wall of the dust collection bin 33, and is finally discharged from the dust discharge port 331, thus facilitating the discharge and collection of residue.
[0031] Please see Figure 1 In one embodiment of this utility model, in order to allow dust to flow out of the connecting port 31 in an orderly manner, the polishing device 100 also includes a side mesh plate 50. The side mesh plate 50 is provided with a plurality of second through holes 51. The side mesh plate 50 is attached to the inner wall of the chamber 10 and is located on the inner side of the chamber 10 where the dust outlet 11 is located. Thus, through the setting of the side mesh plate 50, fine dust can be gradually discharged through the second through holes 51 and gradually collected by the exhaust fan 40.
[0032] Further, please refer to Figure 1 In this embodiment, the exhaust hood 32, when installed, has a vertical cross-section including a guide wall 321 and a vertical wall 322. The guide wall 321 is connected to the hopper 10 and is inclined downwards. The vertical wall 322 is connected to the ash collection hopper 33 and is also arranged vertically. That is, under the guidance of the inclined guide wall 321, the dust gradually moves downwards and eventually moves downwards along the vertical wall 322 for collection through the connecting port 31. It can be understood that because the exhaust hood... The exhaust hood 32 needs to be installed outside the silo body 10. The exhaust hood 32 may include three guide walls 321 connected in sequence and three vertical walls 322 connected in sequence. One vertical wall 322 is connected to one guide wall 321. Two guide walls 321 and two vertical walls 322 are connected to the silo body 10 and the ash collection silo 33. One vertical wall 322 is arranged opposite to the silo body 10 and is connected to the ash collection silo 33. At the same time, the guide wall 321 connected to the vertical wall 322 is connected to the silo body 10.
[0033] Please see Figure 1 In one embodiment of this utility model, in order to facilitate the centralized collection of residual slag in the ash collection bin 33, the grinding device 100 also includes an ash discharge door 60. The ash discharge door 60 is used to open or close the dust discharge port 331. That is, during the grinding process, the ash discharge door 60 is in a closed state to the dust discharge port 331. When it is necessary to discharge residual slag, the ash discharge door 60 is opened so that the large-particle residual slag can be discharged and collected in a centralized manner to avoid scattering on the ground and generating dust again.
[0034] Furthermore, such as Figure 1 As shown, large-particle residue falls onto the ash discharge door 60 and is collected by it. The residue exerts pressure on the ash discharge door 60. To facilitate the collection of residue, the ash discharge door 60 is opened or closed by rotating relative to a horizontally positioned first rotating shaft 70. That is, the ash discharge door 60 is equipped with a horizontally positioned first rotating shaft 70. As the ash discharge door 60 is opened, the gravity of the residue drives the ash discharge door 60 to rotate downwards. Simultaneously, the residue can gradually flow downwards along the wall of the ash discharge door 60 and be collected. The rotation direction of the ash discharge door 60 is as follows: Figure 1 As shown by arrow a in the diagram.
[0035] Understandably, the grinding device 100 also includes a locking structure 80, which is connected to the ash collection hopper 33. When the ash discharge door 60 is closed relative to the dust discharge port 331, the locking structure 80 locks the ash discharge door 60. The locking structure 80 may include a second rotating shaft 81, a locking rod 82, a locking nut 83, and a handle 84. The second rotating shaft 81 is located in the ash collection hopper 33. The ash discharge door 60 is provided with a latch. The locking rod 82 rotates relative to the second rotating shaft 81 under the drive of the handle 84 to engage or disengage from the latch. When the ash discharge door 60 is locked, the locking rod 82 is locked in the latch, and the locking nut 83 is rotated relative to the locking rod 82. At this time, rotating the nut will lock the ash discharge door 60.
[0036] Please see Figure 1 In one embodiment of this utility model, since the exhaust fan 40 needs to circulate air when exhausting, the silo body 10 in this embodiment includes a main body 12 and a silo top 13 located on top of the main body 12. The main body 12 is provided with a dust outlet 11 and a grinding platform 20. The cross-section of the silo body 10 along the vertical plane is trapezoidal. Thus, the silo top 12 is set in an arched manner to adapt to the arc-shaped flow of air, so as to reduce the air resistance when the air flows at the corners and facilitate the circulation of air to drive the flow of dust.
[0037] The aforementioned grinding device 100, by configuring the dust collection hood 30 as an air outlet hood 32 and a dust collection bin 33 with interconnected inner cavities, allows fine dust generated during the grinding process to gradually enter the air outlet hood 32 through the dust outlet 11 under the suction of the exhaust fan 40, and be extracted by the exhaust fan 40; simultaneously, some large particles of residue fall into the dust collection bin 33 by their own gravity through the first through hole 21 of the grinding platform 20, and are ultimately collected or discharged by the dust collection bin 33, achieving the collection of dust particles of different sizes; by setting the connecting port 31 in the dust collection bin 33, the exhaust fan 40 is closer to the larger particles of residue, and the larger particles of residue are collected. Dust mixed in can also be sucked out; the diameter of the ash collection bin 33 gradually decreases from the grinding platform 20 toward the dust discharge port 331, and the residue gradually slides toward the dust discharge port 331 by its own gravity, avoiding adhesion to the side wall of the ash collection bin 33, and is finally discharged from the dust discharge port 331; by setting a side mesh plate 50 on the inner side of the ash outlet 11, fine dust can be gradually discharged through the second through hole 51 and gradually collected by the exhaust fan 40; by setting an ash discharge door 60 at the dust discharge port 331, the residue is collected by the ash discharge door 60 and discharged, avoiding direct scattering on the ground and generating dust again.
