Description

Technical Field

[0001] The invention relates to the technical field of feeding devices, in particular to a fly ash feeding device. Background Art

[0002] Fly ash refers to the ash produced during the combustion process of coal-fired power plants. These ashes are mainly composed of silicon, aluminum and iron oxides, and also contain carbon and some other minerals. At present, fly ash has been widely used in the industry as a mixed material added to cement clinker. At the same time, fly ash can also be used as a basic material for the aluminum industry. Usually, fly ash is stored in a storage tank as a raw material. During production, fly ash is discharged from the pipe at the bottom of the storage tank to the feeding device and transported by the feeding device.

[0030] In this embodiment, the driving member drives the dredging rods 310 on both sides to extend into the discharge pipe 101 at intervals to squeeze and dredge the fly ash. At the same time, the driving member can also drive the knocking rods 510 to knock the outer wall of the discharge pipe 101 at intervals to achieve the effect of stable discharge of the discharge pipe 101; Among them, through the setting of the scraping and sweeping component, the scraping and sweeping component can scrape the inner wall of the storage tank 100 to prevent fly ash from adhering to the inner wall of the storage tank 100. At the same time, the fly ash dropped by the scraping can be discharged from the discharge pipe 101, so that the unloading effect of the storage tank 100 is better.

Therefore, when it is necessary to scrape the fly ash attached to the inner wall of the storage tank 100, the rotating rod 132 is driven to rotate by the second motor 131, so that the scraper 810 can scrape the inner wall of the storage tank 100, thereby causing the fly ash attached to the inner wall of the storage tank 100 to fall off so that it can be discharged from the discharge pipe 101.

[0032] In this embodiment, the driving member includes a mounting frame 320 arranged on the outer wall of the discharge pipe 101, a slidable bracket 330 is provided on the mounting frame 320, the other end of the dredging rod 310 is rotatably mounted on the bracket 330, a driving slide groove 331 is provided at the center position of the bracket 330 along the axial direction of the discharge pipe 101, a rotatable turntable 520 is provided on the mounting frame 320, and a driving slide column 340 sliding in the driving slide groove 331 is provided on the side of the turntable 520 and near the edge.

[0033] In this embodiment, both ends of the mounting frame 320 are bent to form mounting ears, and the mounting ears are fixedly mounted on the outer wall of the discharge pipe 101 by screws to achieve fixed installation of the mounting frame 320; Specifically, combined Figure 5 and Figure 6 As shown, extension plates 630 are provided on both sides of the mounting frame 320 along the moving direction of the bracket 330, and slide rails 631 are provided on the extension plates 630 along the extending direction thereof, and sliders are provided on the sides of the bracket 330 to slide on the corresponding slide rails 631, thereby preferably realizing the sliding installation of the bracket 330 on the mounting frame 320; The turntable 520 is located between the mounting frame 320 and the bracket 330. Specifically, the turntable 520 is rotatably mounted on the mounting frame 320 through a rotating shaft, so that the turntable 520 rotates to drive the driving slide column 340 to rotate, so that the drive slide column 340 squeezes the side wall of the driving slide groove 331 to drive the bracket 330 to move back and forth, thereby driving the dredging rods 310 on both sides of the discharge pipe 101 to extend into the discharge pipe 101 at intervals; It should be noted that during the telescopic movement of the dredging rod 310, the inserted end thereof does not separate from the discharge pipe 101, thereby ensuring that the dredging rod 310 can relatively stably squeeze and dredge the fly ash in the discharge pipe 101; Among them, a first motor 360 for driving the rotating shaft to rotate is arranged on the mounting frame 320. By utilizing the first motor 360 to drive the rotating disk 520 to rotate, the operation of the dredging member can be better realized.

[0034] Combination Figure 6-Figure 7 As shown, in this embodiment, the knocking member also includes a knocking box 350 arranged on the mounting frame 320, the knocking rod 510 is arranged in parallel in the knocking box 350, and a mounting rod 710 is provided in the knocking box 350 corresponding to the knocking rod 510, and one end of the knocking rod 510 located in the knocking box 350 is slidably sleeved on the corresponding mounting rod 710, and the end of the knocking rod 510 located in the knocking box 350 extends outward to form a mounting portion 721, and a spring 722 is sleeved on the knocking rod 510, and the spring 722 is used to push the knocking rod 510 to retract into the knocking box 350, and a power member for driving the knocking rod 510 to extend out at intervals is provided in the knocking box 350.

[0035] In this embodiment, the knocking box 350 is fixed on the mounting frame 320 by bolts, and two knocking rods 510 are arranged radially side by side in the knocking box 350 along the discharge pipe 101, wherein the knocking rod 510 can be extended and retracted in the knocking box 350 through the coordinated arrangement of the spring 722 and the power part, and the end of the knocking rod 510 extending outside the knocking box 350 hits the outer wall of the discharge pipe 101, thereby causing the fly ash in the discharge pipe 101 to vibrate.

[0036] In this embodiment, the power part includes a rotating rod 730 rotatably arranged on the knocking box 350, the rotating rod 730 is located between the knocking rods 510, and an inclined rotating wheel 731 is provided on the rotating rod 730. The rotating rod 730 rotates to drive the rotating wheel 731 to squeeze the installation part 721 at intervals to realize the extension and retraction of the knocking rod 510.

[0037] In this embodiment, the two ends of the rotating rod 730 are rotatably installed in the knocking box 350 through bearings. Therefore, when the rotating rod 730 drives the rotating wheel 731 to rotate, the rotating wheel 731 rotates to squeeze the corresponding mounting portion 721 at intervals, so that the knocking rod 510 is extended, and the spring 722 drives the knocking rod 510 to retract, so that the rotating rod 730 continues to rotate to drive the knocking rod 510 to extend and retract at intervals, thereby knocking the outer wall of the discharge pipe 101. In actual use of this embodiment, one end of the rotating rod 730 is extended out of the knocking box 350, and a driven sprocket 610 is provided at the extended end of the rotating rod 730. A driving sprocket is provided on the rotating shaft, and a chain 620 is sleeved between the driving sprocket and the driven sprocket 610.

[0038] In this embodiment, through the coordinated arrangement of the active sprocket, the driven sprocket 610 and the chain 620, the first motor 360 drives the bracket 330 to move back and forth, driving the dredging rod 310 to perform dredging operations, and can drive the knocking rod 510 to knock on the discharge pipe 101 at intervals to cause it to vibrate, thereby making the dredging effect of the dredging component 120 better.

[0039] In this embodiment, a rotating part is provided on the outer wall of the discharge pipe 101 corresponding to the dredging rod 310, and the rotating part is used to drive the dredging rod 310 to rotate when the dredging rod 310 is extended and retracted at intervals; by allowing the dredging rod 310 to reciprocate while moving in the discharge pipe 101, the dredging rod 310 can thereby improve the dredging effect of the dredging rod 310 on the discharge pipe 101.

[0040] In this embodiment, the rotating part includes a fixed cylinder 370 fixedly installed on the outer wall of the discharge pipe 101, and a spiral sliding groove is arranged on the inner wall of the fixed cylinder 370. A spiral sliding block 410 that cooperates with the sliding groove is arranged on the outer wall of the dredging rod 310. When the dredging rod 310 moves along the fixed cylinder 370, the sliding block 410 slides along the sliding groove to realize the rotation of the dredging rod 310.

[0041] Through the structure of this embodiment, in actual use, when the dredging rod 310 is extended into the discharge pipe 101 along the fixed cylinder 370, the sliding block 410 slides in the sliding groove, thereby driving the dredging rod 310 to rotate forward, so that the dredging rod 310 can rotate and squeeze the fly ash in the discharge pipe 101. When the dredging rod 310 is extended out of the discharge pipe 101 along the fixed cylinder 370, the sliding block 410 slides in the sliding groove, thereby driving the dredging rod 310 to reverse, so that the dredging rod 310 is reset; It should be noted that during the extension and retraction of the dredging rod 310 , the portion on which the sliding block 410 is arranged does not extend into the discharge pipe 101 to avoid material getting stuck on the sliding block 410 , which would cause it to fail to operate normally.

[0042] Specifically, the outer end of the dredging rod 310 is provided with a threaded rod that passes through the bracket 330, and a nut is threadedly connected to the threaded rod, thereby realizing the rotatable installation of the dredging rod 310 on the bracket 330.

[0043] In this embodiment, in order to improve the effect of the dredging rod 310 in rotating and dredging the fly ash, a conical portion 530 is provided at the end of the dredging rod 310 extending into the discharge pipe 101, and spiral scrapers 531 are distributed along the circumference of the frustum of the conical portion 530. The rotation of the dredging rod 310 drives the spiral scrapers 531 to rotate and squeeze the fly ash, which can better improve its rotational dredging effect.

[0044] During actual use of this embodiment, when the discharge pipe 101 is discharging fly ash in the storage tank 100, the drive motor 113 is started to drive the spiral blade 210 to feed and convey the material. At the same time, the first motor 360 is started to drive the clearing rod 310 to extend into the discharge pipe 101 at intervals. At the same time, the knocking rod 510 is driven to knock on the outer wall of the discharge pipe 101 at intervals to prevent the fly ash in the discharge pipe 101 from being blocked, thereby improving the stability of the discharge of the discharge pipe 101.

[0045] In conclusion, the above is only a preferred embodiment of the present invention, and all equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the patent of the present invention.
