When the powder conveying device is used, the situation that the sealing performance of the device is reduced because the interior of the filter cartridge 90 can be cleaned only by disassembling and assembling the bin top during cleaning after the filter cartridge 90 in the tank 10 for conveying powder is used for a long time is solved, according to the powder conveying device, when a large amount of powder is flushed into the tank 10 for conveying through the tank 10, the end cover 20, the filter cartridge 90, the dust blowing pulse valve 110, the blowing pipe and the air bag 30, the powder enters the tank 10 and then moves downwards to the material rotating body 50, the conveying shaft is driven to rotate by the conveying motor 100 connected with the material rotating body 50, the powder is pushed to the material discharging body 120 through the conveying shaft, and when the powder reaches the material discharging body 120, the powder is discharged through an opening below the material discharging body 120, so that the dust pollution caused by manual powder conveying is reduced. When powder is conveyed, powder is conveyed in the tank body 10, so that dust generated by the powder cannot leak out of the tank body 10, and pollution caused by the dust is further reduced, but after the powder enters the tank body 10, high-pressure gas enters the tank body 10 and is conveyed in the conveying process, high pressure is formed in the tank body 10 and needs to be discharged, the gas with the dust is carried in the discharging process, if the dust is not treated, the gas with the dust is directly discharged, so that pollution to the working environment is avoided, the gas with the dust is filtered through the filter cartridge 90, the dust is adsorbed on the inner wall of the filter cartridge 90, the gas is discharged through the upper part of the filter cartridge 90 and then is discharged through a dust extraction port arranged on the periphery of the end cover 20, the filter cartridge 90 adsorbing the dust is separated and accumulated after being used for a long time, so that the filtering effect and the air permeability of the filter cartridge 90 are influenced, and the gas in the gas bag 30 is conveyed, the filter cartridge 90 is cleaned by the blowing pipe to blow off the dust adsorbed to the inner wall of the filter cartridge 90, thereby ensuring the permeability of the filter cartridge 90 and preventing the gas with the dust from being discharged to the air. During the maintenance of the filter cartridge 90, the end cover 20 does not need to be removed by crane, because the maintenance and cleaning of the filter cartridge 90 in the tank 10 usually requires the end cover 20 above the tank 10 to be removed for maintenance and treatment of the filter cartridge 90 by manpower, and the method requires re-docking the end cover 20 with the tank 10 after treatment, which is time-consuming and labor-consuming, and if the complete docking is not accurate, powder leakage can be caused, the fixing column 704 is inserted into the locking support 706 after the end cover 20 is attached to the tank 10 and then connected to the inside of the sleeve 702 through the locking support 706, the locking support 706 and the support 701 are fixed through the auxiliary pin 705, and fastening screws are driven through connecting holes arranged on the abutting surfaces of the end cover 20 and the tank 10 for complete sealing, when the cleaning is required, the fastening screws are screwed out, the fixing column 704 is jacked upwards for a certain distance by rotating the jacking stud 703, so that a gap is generated between the abutting surfaces of the end cover 20 and the tank body 10, then the end cover 20 is rotated to circularly rotate around the fixing column 704 to open the end cover 20, and then the filter cartridge 90 is maintained and cleaned.
The embodiment of the invention also discloses a using method of the powder conveying device, which comprises the following steps:
powder is introduced, an external powder device is connected with a material suction pipe 60, the material suction pipe 60 sucks external powder into the tank body 10, then the weight of the powder is sensed by a weighing sensor 80 arranged on the periphery of the tank body 10, and the powder falls into a material rotating body 50;
conveying powder, starting the conveying motor 100 after the powder enters the material rotating body 50, driving a conveying shaft arranged in the material rotating body 50 to rotate by the conveying motor 100, and driving the powder to move towards the right side to enter the material discharging body 120 through a conveying pipeline after the conveying shaft rotates;
feeding, wherein when powder enters the discharging body 120 through the conveying shaft, the telescopic motor retracts to drive the cover plate to be separated from the conveying pipeline, and the powder falls off from the conveying pipeline through the pushing of the conveying shaft to finish discharging;
cleaning dust, when powder is discharged, the dust in the tank 10 is filtered by the filter cartridge 90, the filtered gas is discharged through a dust extraction port formed in the periphery of the end cap 20, and the dust blowing pulse valve 110 opens to blow the filter cartridge 90 through the air bag 30 while the filter cartridge 90 filters the dust, so that the blowing pipe blows the filter cartridge 90 to maintain the air permeability of the filter cartridge 90.
Cleaning the filter cartridge 90, screwing out fastening screws sealed by the end cover 20 and the tank body 10, then rotating the jacking studs 703 to push the fixing posts 704 upwards to move through the jacking studs 703, moving the fixing posts 704 and the end cover 20 upwards, so that a gap is formed between the end cover 20 and the tank body 10, then rotating the end cover 20 around the circle center of the fixing posts 704, so that the end cover 20 is in an open state in a staggered arrangement between the end cover 20 and the tank body 10, and then manually cleaning and maintaining the filter cartridge 90 inside the tank body 10.
