During the production process of cement, it is necessary to convey powdery cement. Generally, when long-distance conveying of powdery objects, a vacuum conveyor can be preferred. The vacuum conveyor mainly consists of a feeding box, a conveying pipe, a bag filter, a vacuum pump, etc. When in use, powdery cement will be added into the interior of the feeding box, and the cement will fall from the bottom end of the feeding box into the interior of the conveying pipe and finally be conveyed inside the conveying pipe.
[0003] However, when adding materials into the interior of the feeding box of the traditional vacuum conveyor, lumped cement powder blocks may fall into the interior of the feeding box. The lumped cement powder blocks are likely to cause blockage of the conveying system during the conveying process, resulting in poor stability in use. Content of the Utility Model

[0025] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, a long-distance conveying device for powdered cement includes a feeding box 1, a support frame 2 is fixedly connected to the bottom end of the feeding box 1, a first filtering structure 3 is provided on the feeding box 1, the first filtering structure 3 includes a handle 301 and a connection frame 302, the connection frame 302 is slidably connected to the feeding box 1, a first filter screen 303 is fixedly connected to the connection frame 302, a stopper 305 is rotatably connected to the feeding box 1, an insertion rod 306 is slidably connected to the stopper 305, two slots 308 are provided on the feeding box 1, and one end of the insertion rod 306 is engaged with one of the slots 308.
[0026] As a technical optimization scheme of the present utility model, asFigure 2 and Figure 6 As shown in Figure 6 , a plurality of rotating shafts 304 are rotatably connected to the feeding box 1, and the top ends of the rotating shafts 304 are in contact with the bottom end of the connecting frame 302, so that it is more labor-saving to pull the connecting frame 302.
[0027] As a technical optimization scheme of the present invention, as Figure 2 and Figure 4 shown, one end of the connecting frame 302 is fixedly connected with a handle 301. The cross-section of one end of the insertion rod 306 is in a T-shaped structure, and the cross-section of the other end of the insertion rod 306 is in a trapezoidal structure, so that it can play a guiding role when the insertion rod 306 is engaged with the slot 308.
[0028] As a technical optimization scheme of the present invention, as Figure 2 shown, a return spring 307 is sleeved outside the insertion rod 306. One end of the return spring 307 is fixedly connected to the insertion rod 306, and the other end of the return spring 307 is fixedly connected to the stopper 305. Therefore, under the action of the return spring 307, the insertion rod 306 can be more firmly engaged with the slot 308.
[0029] As a technical optimization scheme of the present invention, as Figure 1 、 Figure 3 and Figure 7 shown, a feeding structure 4 is provided at the bottom end of the feeding box 1. The feeding structure 4 includes a feeding pipe 401 and a motor 402. The bottom end of the feeding box 1 is fixedly connected with the feeding pipe 401. A motor 402 is installed on the feeding pipe 401. A roller 403 is rotatably connected inside the feeding pipe 401. A plurality of connecting plates 404 are fixedly connected to the roller 403. The output shaft of the motor 402 is fixedly connected to one end of the roller 403. The plurality of connecting plates 404 are circumferentially arranged around the middle of the roller 403. The end of the connecting plate 404 is in contact with the inner wall of the feeding pipe 401, so that the materials inside the feeding box 1 can be conveyed into the connecting pipe 5.
[0030] As a technical optimization scheme of the present invention, as Figure 1 and Figure 5As shown, a connecting pipe 5 is fixedly connected to the support frame 2. The connecting pipe 5 is fixedly connected to the blanking pipe 401. A second filtering structure 6 is provided on the connecting pipe 5. The second filtering structure 6 includes a connecting sleeve 601 and an outer frame 602. One end of the connecting pipe 5 is fixedly connected to the connecting sleeve 601. The outer frame 602 is snap-fitted on the connecting sleeve 601. A second filter screen 603 is fixedly connected to the outer frame 602. A compression sleeve 605 is threadedly connected to the connecting sleeve 601. The compression sleeve 605 abuts against the outer frame 602. A plurality of rotating rods 604 are fixedly connected to the compression sleeve 605. The plurality of rotating rods 604 are circumferentially arranged around the middle of the compression sleeve 605. Therefore, it can prevent relatively large sundries from entering the interior of the conveying system through the end of the connecting pipe 5 and causing blockage to the conveying system.
[0031] When the utility model is in use, the conveying pipeline of cement powder can be connected to one end of the connecting pipe 5 during use. Then, by starting the fan of the conveying system, under the action of the fan, gas will enter the inside of the connecting pipe 5 from the other end of the connecting pipe 5 and flow unidirectionally inside the connecting pipe 5. During the process of entering the inside of the connecting pipe 5, the air can filter out impurities in the air through the second filter screen 603, thus preventing larger impurities from entering the inside of the conveying system and causing blockage to the conveying system. When it is necessary to convey cement powder, the cement powder can be put into the feeding box 1. When the cement powder passes through the first filter screen 303, the first filter screen 303 can filter out larger cement powder lumps in the cement powder, thus preventing the cement powder lumps from entering the inside of the conveying system and causing blockage to the conveying system, effectively improving the stability of use. The cement powder passing through the first filter screen 303 will fall to the bottom end of the feeding box 1. Then, the motor 402 can be started. The rotation of the output shaft of the motor 402 will drive the rotating roller 403 to rotate. The rotation of the rotating roller 403 will drive a plurality of connecting plates 404 to rotate. As the plurality of connecting plates 404 rotate, the cement powder at the top end of the feeding pipe 401 will fall to the bottom end of the feeding pipe 401 and finally fall into the inside of the connecting pipe 5 from the bottom end of the feeding pipe 401. The cement powder falling into the inside of the connecting pipe 5 will move to the inside of the conveying pipeline under the action of the air flow and continue to move inside the conveying pipeline, thus completing the conveying of the cement powder. The cement powder lumps filtered by the first filter screen 303 will gather inside the connecting frame 302. When it is necessary to clean the cement powder lumps, the inserting rod 306 can be pulled, and the return spring 307 will elongate. When the inserting rod 306 is not engaged with one of the slots 308, the blocking block 305 can be rotated. The blocking block 305 will drive the inserting rod 306 to move together. When the end of the inserting rod 306 is facing another slot 308, the return spring 307 will contract to make the inserting rod 306 engaged with another slot 308. At this time, the blocking block 305 rotates 90 degrees and will not resist the connecting frame 302. Then, the connecting frame 302 can be pulled out of the feeding box 1 by holding the handle 301. After being pulled out, it is convenient to clean the cement powder lumps collected inside the connecting frame 302. During the movement of the connecting frame 302, a plurality of rotating shafts 304 will rotate, so that it is more labor-saving when pulling the connecting frame 302, and thus it is more convenient to use. When it is necessary to clean the second filter screen 603, the pressing sleeve 605 can be rotated by holding the rotating rod 604. When the pressing sleeve 605 is twisted off from the connecting sleeve 601, the outer frame 602 can be taken out of the inside of the connecting sleeve 601. After being taken out, the second filter screen 603 can be cleaned.
