Description

Technical Field

[0001] This utility model relates to the field of fly ash brick processing technology, and more specifically, to a feeding device for autoclaved fly ash brick processing. Background Technology

[0002] Autoclaved fly ash bricks are solid bricks made primarily from fly ash and lime, with the addition of appropriate amounts of gypsum and aggregates. They are produced through a process of raw material preparation, pressing, and high-pressure steam curing. There are two types of fly ash bricks: autoclaved fly ash bricks and steam-cured fly ash bricks. Autoclaved fly ash bricks are those cured under high-pressure steam, while steam-cured fly ash bricks are those cured under normal pressure. The production of autoclaved fly ash bricks requires a large amount of raw materials such as fly ash and lime, necessitating the use of a feeding device.

[0003] A search revealed that patent application CN202221953570.9 discloses a feeding device for autoclaved fly ash brick processing, comprising two base plates. A support rod is fixedly connected to the top of one of the base plates. The support rod is connected to a sliding plate via a transmission assembly. The sliding plate is connected to a fixed ring via a rotating assembly. A feeding cylinder is fixedly connected to the inner wall of the fixed ring. A threaded sealing ring is threadedly connected to the bottom of the feeding cylinder. The transmission assembly includes a first servo motor mounted on the top of the support rod, with a transmission screw at the output end of the first servo motor. This invention, by setting up a transmission assembly and a rotating assembly, uses the first and second servo motors to drive the feeding process, making the fly ash feeding more stable. Furthermore, by setting up a threaded sealing ring, the bottom of the feeding cylinder can be opened by rotating the threaded sealing ring during cleaning, thereby achieving thorough cleaning of the inside of the feeding cylinder and ensuring the quality of the fly ash bricks. However, the following drawbacks still exist:

[0004] (1) The feeding device in the prior art feeds materials through a feeding cylinder. However, feeding through the feeding cylinder results in insufficient continuity and intermittent feeding, leading to low feeding efficiency. At the same time, there will be agglomeration in the raw materials, making it inconvenient to crush the agglomerates in the raw materials and affecting subsequent use.

[0005] (2) In the prior art, the feeding device can only feed in a fixed direction and cannot be flexibly adjusted according to the layout of the production line or the material conveying requirements, resulting in poor flexibility of the feeding device.

[0006] Therefore, we have made improvements to this and proposed a feeding device for autoclaved fly ash brick processing. Utility Model Content

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, this embodiment proposes a feeding device for autoclaved fly ash brick processing, including a hopper 1. Two crushing rollers 2 are symmetrically and rotatably connected inside the hopper 1. A transmission gear 3 is rotatably connected to one end of each crushing roller 2 on the same side. A bottom cylinder 4 is fixedly connected to the bottom end of the hopper 1. A first rotating shaft 5 is rotatably connected inside the bottom cylinder 4. A first spiral blade 6 is fixedly connected to the first rotating shaft 5. A first pulley 7 is fixedly connected to the end of one crushing roller 2 away from the transmission gear 3. A first double-groove belt is fixedly connected to the end of the first rotating shaft 5 near the first pulley 7. The first pulley 8 and the first double-grooved pulley 7 are connected to the first double-grooved pulley 8 via the first synchronous belt 9. The first motor 10 is fixedly connected to the bottom cylinder 4. The drive end of the first motor 10 is fixedly connected to the second pulley 11. The second pulley 11 is connected to the first double-grooved pulley 8 via the second synchronous belt 12. The output end of the bottom cylinder 4 is fixedly connected to the feed pipe 13 via a bolt assembly. The outer end of the feed pipe 13 is fixedly connected to the upper feed cylinder 14. The upper feed cylinder 14 is rotatably connected to the second shaft 15. The second spiral blade 16 is fixedly connected to the second shaft 15. A drive mechanism 17 is provided at the bottom, and a conveying cylinder 18 is rotatably connected to the top of the feeding cylinder 14. A reversing mechanism 19 is provided on the conveying cylinder 18, and an output pipe 20 is fixedly connected to the conveying cylinder 18. The first motor 10 drives the second pulley 11 to rotate, which in turn drives the first double-grooved pulley 8 to rotate via the second synchronous belt 12. The rotation of the first double-grooved pulley 8 drives the first rotating shaft 5 to rotate, which in turn causes the first spiral blade 6 to rotate, thereby conveying the crushed raw materials. At the same time, the first double-grooved pulley 8 drives the first pulley 7 via the first synchronous belt 9. The rotation causes the first crushing roller 2 connected to it to rotate. When the crushing roller 2 rotates, the other crushing roller 2 will also rotate in the opposite direction synchronously through the meshing action of the transmission gear 3. When the material enters the hopper 1, it will be clamped and crushed by the two rotating crushing rollers 2, thereby achieving the purpose of crushing agglomerated raw materials and making the raw materials more refined. The crushed raw materials enter the feeding cylinder 14, and the second rotating shaft 15 rotates, thereby driving the second spiral blade 16 to rotate, thereby lifting the raw materials into the conveying cylinder 18, and then flowing out through the output pipe 20.

[0031] like Figure 1 and Figure 4 As shown, in a preferred embodiment, based on the above method, a second double-groove pulley 1701 is fixedly connected to the bottom end of the second rotating shaft 15, a second motor 1702 is fixedly connected to the bottom of the feeding cylinder 14, a third double-groove pulley 1703 is fixedly connected to the drive end of the second motor 1702, and the third double-groove pulley 1703 is connected to the second double-groove pulley 1701 via a belt 1704; the second motor 1702 drives the third double-groove pulley 1703 to rotate, which in turn drives the second double-groove pulley 1701 and the second rotating shaft 15 to rotate via the belt 1704, thereby driving the second spiral blade 16 to perform the feeding operation.

[0032] like Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, in a preferred embodiment, based on the above method, the reversing mechanism 19 further includes a gear ring 1901 fixed to the top of the feed cylinder 14. A mounting plate 1902 is provided on the upper side of the gear ring 1901. The mounting plate 1902 is fixedly connected to the conveying cylinder 18. A servo motor 1903 is fixedly connected to the mounting plate 1902. The drive end of the servo motor 1903 passes through the mounting plate 1902 and is fixedly connected to a reversing gear 1904 that meshes with the gear ring 1901. Two anti-detachment sleeves 1905 are symmetrically provided on the mounting plate 1902 and the gear ring 1901. 05 is fixedly connected to the mounting plate 1902 by bolts; when it is necessary to change the direction of the conveying cylinder 18, the servo motor 1903 is started, which drives the reversing gear 1904 to rotate. Since the reversing gear 1904 is meshed with the gear ring 1901, the mounting plate 1902 and the conveying cylinder 18 will rotate around the central axis of the gear ring 1901, thereby realizing the reversing function of the conveying cylinder 18. The anti-detachment sleeve 1905 ensures the stability of the mounting plate 1902 and the gear ring 1901 during use. Adjusting the direction of the conveying cylinder 18 can convey raw materials to different production equipment and improve the flexibility of the feeding device.

[0033] like Figure 1 and Figure 2 As shown, in a preferred embodiment, based on the above method, a base frame 21 is fixedly connected to the hopper 1, and a sub-frame 22 is fixedly connected to the end of the base frame 21; the base frame 21 and the sub-frame 22 together provide stable support for the hopper 1, ensuring the stability and safety of the hopper 1 during operation.

[0034] like Figure 1 and Figure 2 As shown, in a preferred embodiment, based on the above method, two guide plates 23 are symmetrically and fixedly connected inside the hopper 1. The guide plates 23 are inclined. The function of the guide plates 23 is to guide the material entering the hopper 1 between the two crushing rollers 2, so as to ensure that the material can be crushed by the crushing rollers 2 evenly and effectively, thereby improving the crushing efficiency.

[0035] like Figure 5 and Figure 6As shown, in a preferred embodiment, based on the above method, the bottom end of the conveying cylinder 18 is fixedly connected with a protruding ring 24, and the top end of the feeding cylinder 14 is provided with a groove 25 that matches the protruding ring 24; when the conveying cylinder 18 is connected to the feeding cylinder 14, the protruding ring 24 will be inserted into the groove 25, so as to realize the tight connection and positioning of the conveying cylinder 18 and the feeding cylinder 14, ensure the stability and sealing of the material during the conveying process, and facilitate the rotation of the conveying cylinder 18.

[0036] Specifically, when using this feeding device for autoclaved fly ash brick processing: First, start the first motor 10. The first motor 10 will drive the second pulley 11 to rotate, which in turn drives the first double-grooved pulley 8 to rotate via the second synchronous belt 12. The first double-grooved pulley 8 drives the first pulley 7 to rotate via the first synchronous belt 9, which in turn causes the first crushing roller 2 connected to it to rotate. When the crushing roller 2 rotates, through the meshing action of the transmission gear 3, the other crushing roller 2 will also rotate synchronously in the opposite direction. At the same time, the rotation of the first double-grooved pulley 8 will drive the first rotating shaft 5 to rotate, which in turn causes the first spiral blade 6 to rotate, pouring the raw material into the hopper 1. It will be clamped and crushed by the two rotating crushing rollers 2. The crushed material falls into the bottom cylinder 4, and then... The material is conveyed to the feeding cylinder 14 through the first spiral blade 6. The second motor 1702 drives the third double-grooved pulley 1703 to rotate, which in turn drives the second double-grooved pulley 1701 and the second shaft 15 to rotate through the belt 1704. This drives the second spiral blade 16 to convey the raw material into the conveying cylinder 18, and then it flows out through the output pipe 20. When the feeding direction needs to be adjusted, the servo motor 1903 is started to drive the reversing gear 1904 to rotate. Since the reversing gear 1904 is meshed with the gear ring 1901, the mounting plate 1902 and the conveying cylinder 18 will rotate around the central axis of the gear ring 1901, thereby realizing the reversing function of the conveying cylinder 18. This allows the material to be conveyed to different production equipment, improving the flexibility of the feeding device.

[0037] All technical features in this embodiment can be freely combined according to actual needs.

[0038] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
