[0037] like Figure 1-7 As shown, this embodiment proposes a dust collector applied to large-scale crushing equipment, including a box body 1, a dust removal mechanism 2 is arranged inside the box body 1, a cleaning component 3 is arranged on one side of the box body 1, and a fixing component 4 is arranged inside the box body 1;

[0038] like Figure 4 and Figure 6As shown, the dust removal mechanism 2 includes a fixed plate 201, a bag 202, an air inlet pipe 203, an exhaust pipe 204, a flared portion 205 and an exhaust fan 206. The fixed plate 201 is bolted to the inner wall of the box body 1, the bag 202 is fixedly connected to the inside of the fixed plate 201, the air inlet pipe 203 is connected to one side of the box body 1 and is located below the fixed plate 201, the exhaust pipe 204 is connected to the other side of the box body 1 and is located above the fixed plate 201, the flared portion 205 is welded to one end of the air inlet pipe 203, and the exhaust fan 206 is fixedly connected to the exhaust pipe 2 04, there are several bags 202 which are evenly distributed along the length and width of the fixed plate 201. When in use, the device is placed on one side of the external crushing equipment, and then the exhaust fan 206 is connected to the external power supply and started. The operation of the exhaust fan 206 will put the interior of the box body 1 in a negative pressure state, because the atmospheric pressure will cause the external dust to enter the interior of the box body 1 through the air inlet pipe 203, and then the dust particles in the air are filtered by the bags 202, and then the cleaner air will be drawn out to the outside by the exhaust fan 206, thereby completing the filtration.

[0039] like Figure 6 As shown, the cleaning assembly 3 includes a compressed air pipe 301, a cleaning pipe 302 and a nozzle 303. The compressed air pipe 301 is bolted to the top of the box body 1, and the cleaning pipe 302 is fixedly connected to the output end of the compressed air pipe 301. The nozzle 303 is connected and arranged at the bottom of the cleaning pipe 302 and is located directly above the bag 202. The number of cleaning pipes 302 is several and evenly distributed along the width direction of the fixed plate 201. The number of nozzles 303 is several and evenly distributed along the length direction of the fixed plate 201, and The number of nozzles 303 is the same as the number of bags 202. One end of each of the cleaning tubes 302 is fixedly connected to the output end of the compressed air tube 301. As the air is continuously filtered, the dust on the surface of the bag 202 will accumulate thicker and thicker, and the air resistance will also become greater and greater. At this time, the compressed air tube 301 is started, and compressed air is intermittently sprayed into the cleaning tube 302 and the nozzles 303. Then the compressed air will enter the bag 202 and flush away the dust accumulated on the outer surface of the bag 202, thereby completing the cleaning.

[0040] like Figure 6 As shown, the fixing assembly 4 includes a circular hoop 401 and a connecting rod 402. The circular hoop 401 is fixedly connected to the bottom of the cloth bag 202. The connecting rod 402 is fixedly connected to the side wall of the circular hoop 401 and one end is bolted to the inner wall of the box body 1. When the cloth bag 202 cleans the dust, the circular hoop 401 and the connecting rod 402 will be fixed by the bottom of the cloth bag 202 to prevent the cloth bag 202 from shaking when filtering dust.

[0041] like Figure 5As shown, an inspection opening 5 is provided on the side wall of the box body 1, a switch door 6 is hinged on the inner bottom wall of the inspection opening 5, and a handle 7 is bolted on the side wall of the switch door 6. When a fault occurs inside the box body 1, the switch door 6 can be opened to repair the inside of the box body 1.

[0042] like Figure 5 As shown, a fixing ring 8 is fixedly connected to the outer wall of the exhaust pipe 204, a positioning rod 9 is fixedly connected to the side wall of the fixing ring 8, one end of the positioning rod 9 is fixedly connected to the outer wall of the box body 1, and the number of the positioning rods 9 is several and distributed circumferentially along the central axis of the fixing ring 8. When in use, the fixing ring 8 and the positioning rod 9 can fix the exhaust pipe 204 to prevent the exhaust pipe 204 from shaking when exhausting.

[0043] like Figure 5 As shown, the bottom of the box body 1 is connected to an ash hopper 10, the bottom of the ash hopper 10 is connected to an ash discharge pipe 11, and the outside of the ash discharge pipe 11 is provided with a solenoid valve 12. When the dust is blown off the bag 202, the solenoid valve 12 is opened to discharge the dust from the ash discharge pipe 11 to the outside.

[0044] like Figure 7 As shown, an extension rod 13 is bolted to the inner wall of the ash discharge pipe 11, one end of the extension rod 13 is fixedly connected to a bearing 14, an auger 15 is arranged inside the bearing 14, and the bottom end of the auger 15 is fixedly connected to a first bevel gear 16, and a motor 17 is arranged on the outer wall of the ash discharge pipe 11, and the output end of the motor 17 is fixedly connected to a second bevel gear 18, the output end of the motor 17 passes through the ash discharge pipe 11 and the second bevel gear 18 is meshed with the first bevel gear 16, and the side wall of the auger 15 is tightly fitted with the inner wall of the ash discharge pipe 11. When in use, the motor 17 is started, and the motor 17 drives the second bevel gear 18 to rotate and then rotates the first bevel gear 16 and the auger 15, so that dust is discharged from the inside of the ash discharge pipe 11 in an orderly manner to prevent the ash discharge pipe 11 from being blocked.

[0045] like Figure 1 As shown, the bottom of the ash hopper 10 is bolted with a support leg 19, and the bottom of the support leg 19 is fixedly connected with a stabilizing plate 20. There are four support legs 19 and four stabilizing plates 20, which are distributed circumferentially along the central axis of the drain pipe. When in use, the support legs 19 and the stabilizing plates 20 can improve the stability of the device and prevent the device from falling down.

[0046] like Figure 1 and Figure 4As shown, a pressure sensor 21 is bolted to the inner wall of the box 1, and a pressure gauge 22 is bolted to the outer wall of the box 1. The pressure sensor 21 is electrically connected to the pressure gauge 22. When more dust accumulates on the outer surface of the bag 202, the air resistance will also increase. At this time, the pressure inside the box 1 will rise. Then the pressure sensor 21 measures the pressure inside the box 1 and transmits it to the pressure gauge 22 through an electrical signal, so that the workers can know when the bag 202 needs to be cleaned.

[0047] like Figure 1 As shown, an anti-rust layer is provided on the outer wall of the box body 1, and the material of the anti-rust layer is epoxy resin paint. When in use, the anti-rust layer can prevent the outer wall of the box body 1 from being corroded, thereby increasing the service life of the box body 1.

[0048] Specifically, when the dust collector for large crushing equipment is used: the device is placed in a designated position, and then the exhaust fan 206, the compressed air pipe 301, the motor 17, the solenoid valve 12, the pressure sensor 21 and the solenoid valve 12 are all connected to an external power supply. When removing dust, the solenoid valve 12 is closed and the exhaust fan 206 is started. The operation of the exhaust fan 206 will put the interior of the box 1 in a negative pressure state, because the atmospheric pressure will cause the external dust to enter the interior of the box 1 through the air inlet pipe 203, and then the dust particles in the air are filtered by the bag 202, and then the relatively clean air will be sucked out to the outside by the exhaust fan 206, thereby completing the filtration. As the air is continuously filtered, the bag 2 The dust on the surface of 02 will accumulate thicker and thicker, and the air resistance will become greater and greater. At this time, the pressure sensor 21 senses the data and feeds back to the pressure gauge 22, then stops the exhaust fan 206, opens the solenoid valve 12, and then starts the compressed air pipe 301, and intermittently sprays compressed air into the cleaning pipe 302 and the nozzle 303. Then the compressed air will enter the inside of the cloth bag 202, and the dust accumulated on the outer surface of the cloth bag 202 will be washed off, thereby completing the cleaning. After the cleaning is completed, start the motor 17, and the motor 17 drives the second bevel gear 18 to rotate, and then the first bevel gear 16 and the auger 15 rotate, so that the dust is discharged from the inside of the ash discharge pipe 11 in an orderly manner to prevent the ash discharge pipe 11 from being blocked.

[0049] All technical features in this embodiment can be freely combined according to actual needs.

[0050] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
