[0002] Dust-free feeding is used for unpacking and feeding of small bags of materials in the pharmaceutical, food and chemical industries. Due to the dust removal device, the flying of dust during the feeding process can be avoided. The fertilizer production process also requires the use of dust-free feeding stations to avoid the flying of dust in the production workshop;

[0003] Existing dust-free feeding devices mostly use dust removal devices as the main body to collect and reduce the flying of dust, and existing dust-free feeding devices mostly only use conveying devices and storage devices to cooperate to complete the storage and feeding of materials. In the process of unpacking, some disassembled package fragments will be mixed into the device, causing the storage and feeding device to be easily blocked, and the screening and filtering devices of the existing dust-free feeding devices can only perform simple screening and filtering on the debris, but cannot remove the magnetic impurities in the material, thereby failing to improve the purity of the material; for this reason, the present application designs an intelligent demagnetization dust-free feeding device and a feeding method to solve the above problems.

A scraping brush for abutting against the electromagnetic transmission belt is fixedly connected in the demagnetizing and filtering box.

[0014] The present invention also provides a feeding method for an intelligent demagnetizing and dust-free feeding device, including the following steps:

[0015] S1, firstly, connect the power supply to each electrical appliance and the motor, then take out the powdery or smaller granular materials from the package and pour them into the conveying box on one side of the pneumatic conveying device, and take out the viscous or blocky materials from the package and pour them into the conveying box on one side of the screw conveyor, then the materials are lifted by the belt conveyor and enter the demagnetization filter box. Through the setting of the screw conveyor and the pneumatic conveying device, the device can store the powdery or smaller granular materials and the viscous or blocky materials, so that the application range of the device is improved.

[0016] S2, then the material is transmitted to the electromagnetic transmission belt through the limit of the second material guide sleeve, and then the material is transmitted to the lower end of the drum demagnetization component, and then the electric magnetic separation drum flattens and spreads the material under the action of the compression spring, so that the material is laid smoothly on the electromagnetic transmission belt. At the same time, the middle part of the electric magnetic separation drum starts to rotate driven by the electric rotating device inside the electric magnetic separation drum. During the rotation of the electric magnetic separation drum, the magnetic debris on the upper layer of the material that is in contact with the electric magnetic separation drum can be adsorbed and removed by scraping of the material guide scraper, and then enters the collection box. Through the setting of the electromagnetic transmission belt, the magnetic debris on the lower layer of the material that is closer to the electromagnetic transmission belt can be adhered to the electromagnetic transmission belt, thereby reducing the demagnetization pressure of the drum demagnetization component.

[0017] S3, then the electromagnetic transmission belt drives the material to continue to move forward for transportation, and then moves to the end of the electromagnetic transmission belt. At this time, the material falls, and the fallen material enters the baffle frame through the guidance of the hinged plate, and then passes into the transmission bucket through the second discharge chute in the middle of the baffle frame, and then is transmitted to the storage box through the pipeline via the screw conveyor or pneumatic conveying device at the lower end of the transmission bucket. Before the material passes into the storage box, it is first passed into the bag dust collector for dust removal. Through the setting of the second discharge chute, the processed material can be better passed into the transmission bucket. Through the setting of the first discharge chute and the sliding plug plate, the screened impurities and part of the material can be better discharged into the demagnetization filter box.

[0018] S4, when the material is finally loaded, the storage and loading of the material are completed by the discharge of the second material guide sleeve. When the material passes through the hinged paddle, the vibration motor installed on the side end of the block can be started, so that the top block of the vibration motor repeatedly hits the hinged paddle, causing the hinged paddle to swing up and down, thereby vibrating the material compressed by the electric magnetic separation roller, and the electric swing plate at the lower end of the guide plate can fall and abut on the hinged paddle, so that the vibrated material hits the electric swing plate, and then is introduced into the transmission bucket through the filter hole on the electric swing plate. Some substandard materials enter the collecting bag through the collecting opening, and the electric swing plate vibrates together with the short-distance collision with the hinged paddle, and performs secondary vibration screening on the material in the collecting bag, thereby removing residual material on the material that has not passed. At this point, the use of the device is completed.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: In the present invention, through the blocking cooperation between the second material guiding sleeve and the partition plate, it is convenient to carry out the sealing of material processing, thereby realizing the dust-free operation mode, ensuring the cleanliness of the production environment and protecting the health of employees. Furthermore, the function of discharging and removing magnetic treatment dust leakage can be realized. Through the demagnetization cooperation between the electromagnetic transmission belt and the electric magnetic separation roller, it is convenient to collect the magnetic impurities in the material, improving the quality of the products discharged by the feeding device. Moreover, the function of demagnetizing feeding can be realized. Then, through the vibration cooperation between the articulated baffle and the electric swing plate, it is convenient to vibrate and screen the objects, and the function of removing impurities and screening the material specifications can be realized. Finally, the problems of material doping with magnetic impurities and wide quality specifications are solved. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Working principle: In this embodiment, the present invention also proposes a feeding method of an intelligent demagnetization dust-free feeding device, comprising the following steps:

[0038] Step 1: First, power on all electrical appliances and motors, then take out powdery or small-particle materials from the package and pour them into the conveying box 1 on one side of the pneumatic conveying device 6, and take out viscous or blocky materials from the package and pour them into the conveying box 1 on one side of the screw conveyor 4. Then, the materials are lifted by the belt conveyor and enter the demagnetization filter box 2. Through the arrangement of the screw conveyor 4 and the pneumatic conveying device 6, the device can store powdery or small-particle materials and viscous or blocky materials, thereby improving the application range of the device;

[0039] Step 2: The material is then transferred to the electromagnetic transmission belt 15 through the limit of the second material guide sleeve 9, and then the material is transferred to the lower end of the drum demagnetization assembly, and then the electric magnetic separation drum 16 flattens and spreads the material under the action of the compression spring 32, so that the material is gently laid on the electromagnetic transmission belt 15. At the same time, the electric magnetic separation drum 16 starts to rotate in the middle part of the electric magnetic separation drum 16 driven by the electric rotating device in the electric magnetic separation drum 16. During the rotation of the electric magnetic separation drum 16, the magnetic debris in the upper layer of the material that is in contact with the electric magnetic separation drum 16 can be adsorbed and removed by the scraping of the material guide scraper 31, and then enters the collection box 30. Through the setting of the electromagnetic transmission belt 15, the magnetic debris in the lower layer of the material that is closer to the electromagnetic transmission belt 15 can adhere to the electromagnetic transmission belt 15, thereby reducing the demagnetization pressure of the drum demagnetization assembly;

[0040] Step three, the electromagnetic transmission belt 15 then drives the material to continue to move forward for transportation, and then moves to the end of the electromagnetic transmission belt 15. At this time, the material falls, and the fallen material enters the baffle frame through the guidance of the hinged plate 17, and thus passes into the transmission bucket 5 through the second discharge chute 14 in the middle of the baffle frame, and then is transmitted to the storage box 3 through the screw conveyor 4 or the pneumatic conveying device 6 at the lower end of the transmission bucket 5 through the pipeline. Before the material passes into the storage box 3, it is first passed into the bag dust collector for dust removal. Through the setting of the second discharge chute 14, the processed material can be better passed into the transmission bucket 5. Through the setting of the first discharge chute 13 and the sliding plate 11, the screened impurities and part of the material can be better discharged from the demagnetization filter box 2;

[0041] Step four, when the material is loaded, the storage and loading of the material are completed by the discharge of the second material guide sleeve 9. When the material passes through the hinged plate 17, the vibration motor 26 installed on the side end of the block can be started, so that the top block of the vibration motor 26 repeatedly hits the hinged plate 17, so that the hinged plate 17 swings up and down, thereby vibrating the material compressed by the electric magnetic separation drum 16, and the electric swing plate 20 at the lower end of the guide plate 18 can fall and abut on the hinged plate 17, so that the vibrated material hits the electric swing plate 20, and then is introduced into the transmission bucket 5 through the filter hole on the electric swing plate 20. Some substandard materials enter the collection bag 27 through the collection opening 28. The electric swing plate 20 vibrates together with the short-distance collision with the hinged plate 17, and performs secondary vibration screening on the material in the collection bag 27, so as to remove the residual material on the material that has not passed. At this point, the use of the device is completed.

Then, the electric magnetic separation drum (16) spreads out the materials smoothly under the action of the compression spring (32), so that the materials are gently laid on the electromagnetic conveyor belt (15). At the same time, the middle part of the electric magnetic separation drum (16) starts to rotate driven by the electric rotating device in the electric magnetic separation drum (16). During the rotation of the electric magnetic separation drum (16), magnetic impurities in contact with the upper layer of the materials and the electric magnetic separation drum (16) can be adsorbed and removed by the scraping of the material guiding scraper (31), and then enter the collection box (30). Through the setting of the electromagnetic conveyor belt (15), magnetic impurities in contact with the electromagnetic conveyor belt (15) closer to the lower layer of the materials can be adhered to the electromagnetic conveyor belt (15), thereby reducing the demagnetization pressure of the drum demagnetizing assembly. S3, then the electromagnetic transmission belt (15) drives the material to continue to move forward for transportation, and then moves to the end of the electromagnetic transmission belt (15), at which time the material falls down, and the fallen material is guided by the hinged plate (17) into the baffle frame, and then the second discharge chute (14) in the middle of the baffle frame is passed into the transmission bucket (5), and then transmitted to the storage box (3) through the screw conveyor (4) or the pneumatic conveying device (6) at the lower end of the transmission bucket (5) through the pipeline. Before the material is passed into the storage box (3), it is first passed into the bag dust collector for dust removal. Through the setting of the second discharge chute (14), the processed material can be better passed into the transmission bucket (5), and through the setting of the first discharge chute (13) and the sliding plug plate (11), the screened impurities and part of the material can be better discharged into the demagnetization filter box (2); S4, when the material is finally loaded, the storage and loading of the material is completed by the discharge of the second material guide sleeve (9). When the material passes through the hinged dial plate (17), the vibration motor (26) installed at the side end of the stopper can be started, so that the top block of the vibration motor (26) repeatedly hits the hinged dial plate (17), so that the hinged dial plate (17) swings up and down, thereby vibrating the material pressed by the electric magnetic separation drum (16), and the electric swing plate (20) at the lower end of the guide plate (18) can fall down and abut on the hinged dial plate (17). The plate (17) causes the vibrating material to hit the electric swing plate (20) and then be introduced into the transmission bucket (5) through the filter hole on the electric swing plate (20). Some of the substandard materials enter the collection bag (27) through the collection opening (28). The electric swing plate (20) vibrates together with the articulated plate (17) through a short-distance collision, and performs secondary vibration screening on the material in the collection bag (27), thereby removing the residual material on the material that has not passed through. At this point, the use of the device is completed.
