Description

Technical Field

[0001] The present invention relates to the technical field of powder material conveying, and in particular to a powder material conveying device and a use method thereof. Background Art

[0002] At present, the dust collectors used in powder conveying devices are all silo roof dust collectors, that is, a dust collector is installed on the top of the large tank. Most of the powder silos in domestic mixing stations use silo roof dust collectors. When the powder silo is loaded, the high-pressure gas containing a large amount of dust enters the powder silo and directly enters the dust collector. After being filtered by the filter element in the dust collector, the dust falls back into the large tank, and the filtered gas is discharged into the atmosphere.

[0003] Generally speaking, when the filter element maintains air permeability, the dust collector can basically meet the requirements. However, since the dust collector is on the top of the large tank, whether it is to replace the filter element or perform maintenance, the staff needs to climb to the top of the large tank, which is not only difficult to maintain, but also increases safety hazards. If the routine maintenance is reduced, dust will accumulate or dust will clump inside the filter element, causing the dust collector to basically lose its function. At this time, if the material is loaded, the pressure will increase, the filter element will be damaged, and a large amount of high-pressure gas containing dust will be directly discharged into the atmosphere, causing a large amount of dust pollution. Not only is raw materials wasted, but long-term use will even cause a large amount of powder to accumulate around the dust collector. If it is not cleaned, it will affect the filtering effect of the filter element. When cleaning, the top of the silo needs to be lifted and removed by a crane to clean the filter element in the silo. Repeated disassembly and assembly reduce the sealing of the device and increase the installation time, which is time-consuming and labor-intensive. Summary of the invention

[0015] The embodiment of the present invention also discloses a method for using the powder conveying device, comprising the following steps:

[0016] Introduce powder, connect the external powder device with the suction pipe, the suction pipe draws the external powder into the tank, and then the weighing sensor set on the periphery of the tank senses the weight of the powder, and the powder falls into the transfer body;

[0017] Conveying powder, after the powder enters the material transfer body, the conveying motor is started, and the conveying motor drives the conveying shaft arranged inside the material transfer body to rotate, and after the conveying shaft rotates, the powder is driven to move to the right side through the conveying pipe and enter the inside of the material discharge body;

[0018] Discharging: When the powder enters the discharging body through the conveying shaft, the telescopic motor retracts to drive the cover plate to separate from the conveying pipe, and the powder falls from the conveying pipe through the push of the conveying shaft to complete the discharging;

[0019] To clean the dust, when the powder is discharged, the dust inside the tank is filtered through the filter cartridge, and the filtered gas is discharged through the dust suction port arranged on the periphery of the end cover. While the filter cartridge is filtering the dust, the dust blowing pulse valve is opened to allow the blowing pipe to blow the filter cartridge through the air bag to maintain the air permeability of the filter cartridge.

[0020] The beneficial effects of the present invention are: first, the powder conveying device of the present invention is used to prevent the filter cartridge inside the tank body for conveying powder from being used for a long time. When cleaning, the top of the silo needs to be disassembled and assembled to clean the inside of the filter cartridge, resulting in a decrease in the sealing of the device. First, when a large amount of powder is flushed into the tank body for conveying through the tank body, the end cover, the filter cartridge, the dust-blowing pulse valve, the blowing pipe, and the air bag, the powder enters the tank body and moves downward to the rotating body. The conveying motor connected to the rotating body drives the conveying shaft to rotate, and the powder is pushed to move toward the discharging body through the conveying shaft. When the powder reaches the discharging body, the powder is discharged through the opening below the discharging body, thereby reducing dust pollution caused by manual conveying of powder and reducing powder waste. Secondly, when conveying powder, since the powder is conveyed inside the tank, the dust generated by the powder will not leak out of the tank, further reducing the pollution caused by dust. However, after the powder enters the tank, it is conveyed through high-pressure gas into the tank and then conveyed. High pressure will be formed inside the tank and needs to be discharged. During the discharge process, the gas will carry dust. If it is discharged directly without treatment, it will inevitably cause pollution to the working environment. The gas containing dust is filtered through the filter cartridge, and the dust adsorbed on the inner wall of the filter cartridge is discharged through the top of the filter cartridge, and then discharged through the dust extraction port set on the outer periphery of the end cover. The filter cartridge that adsorbs dust will cause accumulation after long-term use, thereby affecting the filtering effect and air permeability of the filter cartridge. The gas in the air bag is conveyed to the blowing pipe through the dust blowing pulse valve, and the filter cartridge is cleaned through the blowing pipe to blow off the dust adsorbed on the inner wall of the filter cartridge, thereby ensuring the air permeability of the filter cartridge and preventing the gas with dust from being discharged into the air. Third, during the maintenance of the filter cartridge, the end cover does not need to be removed by a crane, because usually the maintenance and cleaning of the filter cartridge in the tank body requires the end cover above the tank body to be removed before the filter cartridge can be maintained manually. This method requires the end cover to be re-jointed with the tank body after treatment, which is time-consuming and labor-intensive. If the joint is not completely and accurately connected, it will cause leakage of powder. Through the bracket, locking bracket, fixing column, sleeve, and auxiliary pin of the locking device, after the end cover and the tank body are fitted, the fixing column is inserted into the locking bracket, and then passed through the locking bracket to connect to the inside of the sleeve, and the lock is locked through the auxiliary pin. The fixed bracket is fixed to the bracket, and the fastening screws are driven through the connecting holes set on the fitting surface of the end cover and the tank body to completely seal. When cleaning is needed, the fastening screws are unscrewed, and the fixing column is lifted up a certain distance by rotating the jacking stud, so that a gap is generated between the fitting surface of the end cover and the tank body, and then the end cover is rotated around the fixing column to open the end cover, and then the filter cartridge is maintained and cleaned. With this method, there is no need to completely separate the end cover and the tank body when maintaining and cleaning the filter cartridge, which reduces the time for reassembling the end cover and the tank body after maintenance is completed, and prevents dust leakage caused by unstable sealing during assembly.

[0051] When in use, the powder conveying device of the present invention is used to prevent the filter cartridge 90 inside the tank body 10 for conveying powder from being used for a long time. When cleaning, the top of the silo needs to be disassembled and assembled to clean the inside of the filter cartridge 90, which causes the sealing of the device to decrease. The present application uses the tank body 10, the end cover 20, the filter cartridge 90, the dust-blowing pulse valve 110, the blowing pipe, and the air bag 30. When a large amount of powder is rushed into the tank body 10 for conveying, the powder enters the tank body 10 and moves downward to the rotating body 50. The conveying motor 100 connected to the rotating body 50 drives the conveying shaft to rotate, and the powder is pushed to move toward the discharging body 120 through the conveying shaft. When the powder reaches the discharging body 120, the powder is discharged through the opening below the discharging body 120, thereby reducing dust pollution caused by manual powder conveying and reducing powder waste. When conveying powder, since the powder is conveyed in the tank body 10, the dust generated by the powder will not leak out of the tank body 10, further reducing the pollution caused by the dust. However, after the powder enters the tank body 10, it is conveyed by high-pressure gas entering the tank body 10. A high pressure gas will be formed in the tank body 10 and needs to be discharged. During the discharge process, the gas will carry dust. If it is discharged directly without treatment, it will inevitably cause pollution to the working environment. The gas containing dust is filtered by the filter cartridge 90, and the dust adsorbed on the inner wall of the filter cartridge 90 is discharged through the top of the filter cartridge 90, and then discharged through the dust extraction port set on the outer periphery of the end cover 20. The filter cartridge 90 that adsorbs dust will cause accumulation after long-term use, thereby affecting the filtering effect and air permeability of the filter cartridge 90. The gas in the air bag 30 is conveyed to the blowing pipe through the dust blowing pulse valve 110, and the filter cartridge 90 is cleaned through the blowing pipe to blow off the dust adsorbed on the inner wall of the filter cartridge 90, thereby ensuring the air permeability of the filter cartridge 90 and preventing the gas with dust from being discharged into the air.During the maintenance of the filter cartridge 90, the end cover 20 does not need to be removed by a crane, because usually the filter cartridge 90 in the tank body 10 needs to be maintained and cleaned by removing the end cover 20 above the tank body 10 so that the filter cartridge 90 can be maintained manually. This method requires the end cover 20 to be re-joined with the tank body 10 after the treatment, which is time-consuming and labor-intensive. If the joint is not completely and accurately connected, it will cause leakage of powder.

[0053] Powder is introduced, and the external powder device is connected to the suction pipe 60, and the suction pipe 60 draws the external powder into the tank body 10, and then the weight of the powder is sensed by the weighing sensor 80 arranged on the periphery of the tank body 10, and the powder falls into the transfer body 50;

[0054] Conveying powder. After the powder enters the material transfer body 50, the conveying motor 100 is started. The conveying motor 100 drives the conveying shaft disposed inside the material transfer body 50 to rotate. After the conveying shaft rotates, the powder moves to the right through the conveying pipe and enters the inside of the material discharge body 120.

[0055] Discharging: When the powder enters the discharge body 120 through the conveying shaft, the telescopic motor retracts to drive the cover plate to separate from the conveying pipe, and the powder falls from the conveying pipe through the conveying shaft to complete the discharging;

[0056] To clean the dust, when the powder is discharged, the dust inside the tank body 10 is filtered through the filter cartridge 90, and the filtered gas is discharged through the dust extraction port arranged on the periphery of the end cover 20. While the filter cartridge 90 is filtering the dust, the dust blowing pulse valve 110 is opened to allow the blowing pipe to blow the filter cartridge 90 through the air bag 30 to maintain the air permeability of the filter cartridge 90.

[0057] Clean the filter cartridge 90, unscrew the fastening screws that seal the end cover 20 and the tank body 10, and then rotate the lifting stud 703 to push the fixing column 704 upward through the lifting stud 703 to move. When the fixing column 704 moves, the end cover 20 also moves upward, thereby creating a gap between the end cover 20 and the tank body 10, and then rotate the end cover 20 around the center of the fixing column 704, so that the end cover 20 and the tank body 10 are staggered and the end cover 20 is in an open state, and then manually clean and maintain the filter cartridge 90 inside the tank body 10.
