Description

Technical Field

[0001] This utility model relates to the field of calcining furnace feeding, and in particular to a vertical calcining furnace anti-clogging quantitative screw feeding device. Background Technology

[0002] The anti-clogging screw feeder for vertical calcining furnace is a device that uses a screw conveyor to feed materials into the furnace evenly and continuously. Its core design adopts a variable pitch or stepped screw structure, combined with anti-clogging measures such as wear-resistant liners, vibrators or reverse blades, to effectively prevent clogging problems caused by material accumulation, bridging or adhesion during the conveying process.

[0003] During the process of feeding raw materials through a screw feeder, uneven feeding can cause an imbalance in the temperature field distribution inside the furnace, resulting in uneven heating of the materials. Some materials may be over-burned or under-burned, affecting the physical and chemical properties of the product. Furthermore, during the raw material transfer process, when some incinerated solid raw materials are transferred, the direct transfer of larger solid raw materials can cause jamming of the screw structure, resulting in blockage of solid raw materials.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figure 1 , Figure 2 and Figure 3This utility model provides an embodiment of a vertical calcining furnace anti-clogging quantitative screw feeding device, comprising: a transmission support frame 1 for bottom support; a support connecting rod 2 fixedly connected to the top left side of the transmission support frame 1; a crushing tank 6 fixedly connected to the top of the support connecting rod 2; a rotating rod 4 rotatably connected inside the crushing tank 6; a first bevel gear 14 fixedly connected to the bottom end of the rotating rod 4; a rotating rod 16 rotatably connected inside the transmission support frame 1; a transmission screw 13 fixedly connected to the outside of the rotating rod 16; a second bevel gear 15 fixedly connected to the left side of the rotating rod 16; the first bevel gear 14 and the second bevel gear 15 meshing with each other; and a feeding frame 3 fixedly connected to the bottom right side of the crushing tank 6. An intermittent feeding assembly is installed inside the feeding frame 3 for use with... To achieve intermittent feeding for calcination, the intermittent feeding assembly includes a baffle plate 19 that slides inside the feeding frame 3. A sliding plate 17 is fixedly connected to the left side of the baffle plate 19. The outer side of the sliding plate 17 is slidably connected to the left side of the feeding frame 3. A toggle cam 5 is fixedly connected to the outside of the rotating rod 4 on the lower side of the crushing tank 6. The outer side of the toggle cam 5 is attached to the left side of the sliding plate 17. A drive motor 7 is fixedly connected to the top center of the crushing tank 6. The drive end of the drive motor 7 is fixedly connected to the top of the rotating rod 4. Outer push plates 21 are fixedly connected to both sides of the sliding plate 17. The inner side of the outer push plates 21 is connected to the left side of the feeding frame 3 through a return spring 20. A blocking traction block 18 is fixedly connected to the inner left side of the feeding frame 3 to restrict and block the feeding.

[0029] During operation, the crushed raw material is discharged downward through the blocking traction block 18. The rotation of the rotating rod 4 drives the actuating cam 5 to rotate synchronously. When the cam protrusion contacts the inner side of the sliding plate 17, it pushes the blocking plate 19 to the right, causing it to engage with the notch at the bottom of the blocking traction block 18, thus temporarily intercepting the raw material. As the cam continues to rotate, when the protrusion disengages from the sliding plate 17, the return spring 20 pushes the outer push plate 21 to the left, causing the blocking plate 19 to retract and reset. The raw material resumes falling. After the falling raw material enters the transmission support frame 1, the rotating rod 4 drives the rotating rod 16 to rotate the transmission screw 13 through the meshing of the first bevel gear 14 and the second bevel gear 15, thus realizing the continuous conveying of the raw material. This working mode, which combines intermittent feeding and continuous conveying, not only ensures the quantitative supply of raw material but also ensures the uniform heating of the material during combustion, significantly improving combustion efficiency and thermal energy utilization.

[0030] Reference Figure 2 , Figure 4 and Figure 6 The rotating roller 8, which is fixed to the upper outer side of the rotating rod 4, is shown in the reference. Figure 5Multiple crushing blades 9 are fixedly connected to the outside of the rotating roller 8. A support frame 11 is fixedly connected to the lower inside of the crushing tank 6. An upward traction component is installed at the top of the support frame 11 to achieve uniform crushing of the calcined raw materials. The upward traction component includes a screen plate 10 nested inside the crushing tank 6. An upward rotating inclined block 22 is fixedly connected to the outside of the rotating rod 4 at the lower side of the screen plate 10. A traction slot 23 is opened in the middle of the bottom end of the screen plate 10. The outside of the upward rotating inclined block 22 is attached to the inside of the traction slot 23. A downward guide block 12 is fixedly connected to the bottom inside the crushing tank 6 to achieve downward traction of the raw materials. Multiple limiting sliders 24 are fixedly connected to both sides of the screen plate 10. The outside of the limiting sliders 24 is slidably connected to the inside of the crushing tank 6, and the top height of the limiting sliders 24 is lower than the lower side of the rotating roller 8.

[0031] After the raw material to be processed is put into the inner cavity of the crushing tank 6, the drive motor 7 is started to drive the rotating rod 4 to rotate, which in turn drives the rotating roller 8 and the multiple crushing blades 9 on its surface to crush the raw material. At the same time, the rotating rod 4 synchronously drives the upward rotating inclined block 22 to rotate. Its top inclined surface interacts with the inclined surface inside the traction slot 23. During the rotation, the screening plate 10 is periodically lifted, causing it to generate an upward impact motion. This design achieves a dual function: on the one hand, the raw material to be crushed is continuously thrown up to ensure that it is in full contact with the crushing blades 9, thereby improving the uniformity of crushing; on the other hand, it promotes the falling of qualified particles through the screen holes of the screening plate 10 and guides them to the right discharge port through the lower guide block 12. This dynamic screening mechanism effectively prevents the spiral conveyor from being blocked by material accumulation, and significantly improves the overall crushing efficiency and product quality.

[0032] Working principle: The raw material to be added is placed inside the crushing tank 6. At this time, the drive motor 7 is started, and the rotating rod 4 is rotated, which in turn drives the rotating roller 8 to rotate. The raw material is crushed by multiple crushing blades 9. The rotation of the rotating rod 4 also drives the upward rotating inclined block 22 to rotate. The inclined surface at the top of the upward rotating inclined block 22 contacts the inclined surface inside the traction slot 23. As the upward rotating inclined block 22 rotates, it pulls the screening plate 10 upward, thereby generating an upward impact force. The raw material on the surface of the screening plate 10 is thrown upward, so that it comes into uniform contact with the crushing blades 9 for crushing. The crushed raw material is discharged downward through the holes of the screening plate 10 and discharged to the right through the lower guide block 12, which improves the uniformity of the crushing of the raw material and avoids the spiral from getting blocked. The crushed raw material enters the inside of the feeding frame 3 and is discharged downward through the blocking traction block 18. The rotation of lever 4 also drives the rotating cam 5 to rotate. The outer protrusion of the rotating cam 5 contacts the inner side of the sliding plate 17, thereby pushing the blocking plate 19 to the right and blocking the blocking traction block 18 at the bottom notch, thus blocking the raw material. When the protrusion of the rotating cam 5 disengages from the inner side of the sliding plate 17, the return spring 20 pushes the push plate 21 to the left, thereby retracting the blocking plate 19, and the raw material is discharged again. The raw material enters the interior of the transmission support frame 1. As the rotating lever 4 rotates, the first bevel gear 14 rotates. The first bevel gear 14 meshes with the second bevel gear 15, thereby rotating the rotating lever 16. The transmission screw 13 rotates accordingly, thereby transmitting the raw material. The raw material falls intermittently, thus completing the intermittent transmission of the raw material, improving the efficiency of the raw material combustion, and improving the uniform heating of the material.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
