[0048] As one of the technical optimization schemes of the present application, a powder material conveying method comprises the conveying device described above, and further comprises the following steps:

[0049] Step one: one end of the conveying pipeline 1 is connected with a preset Roots blower, the other end of the conveying pipeline 1 is connected with a preset collecting container, and then the powder material to be conveyed is placed in the feeding bin 3, enters the inside of the feeding port 2 from the discharge port at the bottom of the feeding bin 3, and enters the inside of the conveying pipeline 1, and the powder material in the conveying pipeline 1 is pneumatically conveyed by the air force discharged by the Roots blower;

[0050] Step two: if there are a small amount of agglomerates in the powder material to be conveyed, the agglomerates mixed in the powder material are automatically filtered when the powder material enters the inside of the feeding bin 3, and then the two sliding blocks 21 are controlled to move back and forth in the corresponding sliding groove 5, the two first electric telescopic rods 22, the connecting rod 23 and the moving plate 8 are driven to move synchronously, so that the moving plate 8 automatically crushes the agglomerates temporarily stored on the top of the filter plate 7 during the movement;

[0051] Step three: if a small amount of metal impurities are mixed in the powder material to be conveyed, the two partition plates 11 in the feeding bin 3 are controlled to rotate upwards to a horizontal state before the conveying pipeline 1 conveys the powder material, at this time, the powder material entering the inside of the feeding bin 3 is temporarily stored in the feeding bin 3, the multiple electromagnets 10 are controlled to generate magnetic force, the multiple rectangular plates 9 and the electromagnets 10 are driven by the driving motor 25 to rotate on the top of the two partition plates 11, and a small amount of metal impurities mixed in the powder material are automatically absorbed and collected by the multiple electromagnets 10 with magnetic force;

[0052] Step four: if some sticky powder materials need to be transported, repeat the above steps for powder materials containing a small amount of metal impurities, so that the powder material entering the inside of the feed bin 3 is accumulated on the top of the two baffles 11, and the preset electric heating block inside the two baffles 11 is started to heat the powder material accumulated on the top of the two baffles 11;

[0053] Step five: after the heating treatment of the sticky powder material, the telescopic ends of the two third electric telescopic rods 18 are controlled to retract to the original position, so that the two drive plates 12 are reset by the elastic reset of the two springs 13, the drive motor 25 drives the rotation of the plurality of rectangular plates 9, and the rectangular plates 9 push the end of the two drive plates 12 away from the rotating part, and after the rectangular plates 9 rotate away from the drive plates 12, the drive plates 12 are impacted by the rubber blocks 14 and the corresponding blocking blocks 17 driven by the two springs 13, so that the whole feed bin 3 vibrates to reduce the probability of blockage of the sticky powder material during transportation.

[0054] In the present application, when the user uses the device, one end of the conveying pipeline 1 is connected with the output end of the external preset Roots blower, and the other end of the conveying pipeline 1 is connected with the preset collection container. At this time, the powder material to be transported can be placed in the inside of the feed bin 3. After the powder material passes through the filter plate 7, it can enter the inside of the feed inlet 2 from the discharge port at the bottom of the feed bin 3, and then enter the inside of the conveying pipeline 1. The powder material in the conveying pipeline 1 is pneumatically transported by the air exhaust of the Roots blower. After the powder material is transported by the conveying pipeline 1 and discharged into the preset collection container, the transportation of the powder material is completed.

[0055] If there are a small amount of lumps in the powder material to be transported, in order to avoid the lumps directly entering the inside of the conveying pipeline 1 for transportation, causing the conveying pipeline 1 to be easily blocked, when the powder material enters the inside of the feed bin 3, the filter plate 7 can automatically filter the lumps mixed in the powder material, and the lumps are temporarily stored on the top of the filter plate 7. Then, the two first electric telescopic rods 22, the connecting rod 23 and the moving plate 8 can be moved back and forth by controlling the two sliding blocks 21 to move back and forth in the corresponding sliding slot 5, so that the moving plate 8 can automatically crush the lumps temporarily stored on the top of the filter plate 7 during the back and forth movement on the top of the filter plate 7. After the crushed lumps pass through the filter plate 7, they can be transported together with the subsequent powder material into the inside of the conveying pipeline 1, reducing the probability of blockage of the conveying pipeline 1, and facilitating the device to quickly transport the powder material containing lumps.

[0056] And, like the powder material to be mixed with a small amount of metal impurities, in order to avoid these metal impurities into the conveying pipe 1 inside and fast moving process, the inner wall of the conveying pipe 1 caused by abrasion, reduce the service life of the conveying pipe 1, can be transported before the conveying pipe 1 to such powder material, first control the two baffle 11 in the feed bin 3 inside the upward rotation together to the horizontal state, so that the mutual splicing to the feed bin 3 bottom of the discharge port for plugging, at this time into the feed bin 3 inside the powder material will be after passing through the filter plate 7 fall in the top of two baffle 11, and in the feed bin 3 inside the temporary storage processing, then control a plurality of electromagnet 10 are energized to start generating magnetic force, with the aid of the drive motor 25 drive mounting seat 26 and two rotating plate 27 synchronous slow rotation, drive a plurality of rectangular plate 9 and electromagnet 10 together on the top of two baffle 11 rotation, so that a plurality of electromagnet 10 can be in contact with the powder material in the process of rotation, but also can control two screw 16 rotation drive two sealing block 17 received in the receiving slot 15 inside, so that two through slot 6 exposure, control two third electric telescopic rod 18 telescopic end together with the extension, drive two moving block 19 are away from the direction of the feed bin 3 movement, so that two moving block 19 can be pulled two driving plate 12 respectively, drive two rubber block 14 through the corresponding through slot 6, so that two driving plate 12 rotation to the state of parallel with the inner wall of the feed bin 3 side, at this time can be with the aid of two sliding block 21 in the corresponding sliding slot 5 inside back and forth movement, drive the moving plate 8 on the top of the filter plate 7 movement, also can drive mounting seat 26 and a plurality of rectangular plate 9 on the bottom of the filter plate 7 synchronous back and forth movement, so that a plurality of electromagnet 10 can be more fully contacted with the powder material, a small amount of metal impurities mixed in the powder material can be in the process of moving and rotating a plurality of rectangular plate 9, automatically by the magnetic force of a plurality of electromagnet 10 adsorption collection, that is, to achieve the effect of automatic removal of a small amount of metal impurities mixed in the powder material.

[0057] After a small amount of metal impurities in the powder material are adsorbed and collected by the plurality of electromagnets 10, the two partition plates 11 are controlled to rotate downward to reset, so that the treated powder material can enter the inside of the conveying pipeline 1 through the feeding port 2 for conveying. Then the extension ends of the two first electric telescopic rods 22 are controlled to extend upward together, driving the two connecting rods 23, the moving plate 8, the filter plate 7 and the mounting seat 26 to move upward together inside the feeding bin 3, until the height of the plurality of rectangular plates 9 is higher than the height of the two driving plates 12, then the two rotating plates 27 are controlled to rotate upward together inside the mounting seat 26 to a horizontal state, driving the plurality of rectangular plates 9 to be inserted in the corresponding filter grooves, the extension ends of the two second electric telescopic rods 28 inside the plurality of rectangular plates 9 are controlled to extend upward together, driving the corresponding electromagnets 10 to pass through the corresponding filter grooves upward and move above the filter plate 7. Then the extension ends of the two first electric telescopic rods 22 are continuously controlled to extend upward, until the plurality of rectangular plates 9 move to the outside of the feeding bin 3, then the plurality of electromagnets 10 lose magnetism after being controlled to be powered off, so that the metal impurities collected by the plurality of electromagnets 10 fall downward on the top of the filter plate 7, the plurality of filter grooves are blocked at the bottom ends by the plurality of rectangular plates 9, so that the metal impurities falling into the filter grooves will not fall into the inside of the feeding bin 3 again. Then the metal impurities on the top of the filter plate 7 and in the filter grooves can be cleaned by manually holding a dust collection device or other device with magnetic force, so as to quickly collect and remove a small amount of metal impurities in the powder material, avoiding the adverse effects of metal impurities in the powder material conveying process.

[0058] At the same time, if some powder materials with high viscosity need to be conveyed, in order to reduce the difficulty of conveying such powder materials, the above steps for treating powder materials containing a small amount of metal impurities can be repeated, so that the powder material entering the inside of the feeding bin 3 is accumulated on the top of the two partition plates 11. At this time, the preset electric heating block or electric heating wire inside the two partition plates 11 can be controlled to be powered on to start, so that the heat generated by the two partition plates 11 can heat treat the powder material accumulated on the top. During the heating process of the powder material, the above steps of rotating and moving back and forth of the plurality of rectangular plates 9 inside the feeding bin 3 can also be repeated, so that the powder material can be dispersed and stirred, improving the heating efficiency of the powder material and ensuring that the powder material with high viscosity can be quickly and stably conveyed in the inside of the conveying pipeline 1, reducing the difficulty of conveying the powder material with high viscosity by the device.

[0059] After the heating treatment of the powder material with high viscosity, the two partitions 11 are slowly rotated downward, so that the powder material can enter the inside of the conveying pipeline 1 downward. At this time, the extension end of the two third electric telescopic rods 18 is retracted to the original position, so that the two drive plates 12 are reset by the elastic reset of the two springs 13. The drive motor 25 drives the mounting seat 26, the rotating plate 27 and the plurality of rectangular plates 9 to rotate synchronously, so that the rectangular plates 9 can push the end of the two drive plates 12 away from the rotating position while rotating clockwise, drive the two corresponding springs 13 to be in a stretched state, and after the rectangular plates 9 rotate away from the drive plates 12, the drive plates 12 lose the pushing force and are reset by the elastic reset of the two springs 13, so that the rubber blocks 14 can collide with the corresponding blocking blocks 17, so that the whole feeding bin 3 vibrates. With the continuous impact of the two rubber blocks 14 on the blocking blocks 17 and the continuous rotation of the plurality of rectangular plates 9 in the inside of the feeding bin 3, the probability of blockage of the powder material during downward conveying in the feeding bin 3 can be reduced, and the conveying efficiency of the powder material can be further improved.

The two or more powder materials can be automatically mixed and stirred before conveying, without the need for additional mixing and stirring equipment to mix and stir them first, and then the powder material conveying work is carried out, so that the device can effectively improve the conveying efficiency when conveying two or more powder materials.

[0061] When the conveying work of the device for the powder material is about to be completed, and there is no powder material to be added into the inside of the feeding bin 3, and the Roots motor at one end of the conveying pipeline 1 is still in the open state, the drive motor 25 can continue to drive the mounting seat 26 and the plurality of rectangular plates 9 below it to rotate in the inside of the feeding bin 3, so that it can continuously push the two drive plates 12, and the two rubber blocks 14 can continuously cooperate with the corresponding blocking blocks 17 to clean and remove a small amount of powder material attached to the inner wall of the feeding bin 3 by vibration, and the cleaned powder material is continuously conveyed to the preset collecting container through the conveying pipeline 1 for storage, reducing the loss and waste of the powder material during conveying.

[0062] After the conveying work of the device to the powder material is completed, after the related parts such as the feeding bin 3 are cleaned, the two rotating plates 27 are controlled to rotate upward together in the inside of the mounting seat 26 to a horizontal state, drive the plurality of rectangular plates 9 to block the plurality of filter grooves in the filter plate 7, then control the extension ends of the two first electric telescopic rods 22 to extend upward together, drive the moving plate 8 and the filter plate 7 and a plurality of components to move upward together to the top of the feeding bin 3, at this time, the filter plate 7 whose plurality of filter grooves are blocked by the plurality of rectangular plates 9 can be used as the cover plate of the feeding bin 3, block the top opening of the feeding bin 3, avoid the problem that when the device is not used, foreign matters from the opening into the inside of the feeding bin 3.
