[0031] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0032] like Figures 1 to 9 As shown, the present invention provides a technical solution: a molecular sieve raw material lifting and conveying device, including a lifting platform 1, a feed plate 2 fixedly installed on the top of the lifting platform 1, the feed plate 2 being in an inclined state, a movable frame 3 slidably connected to the top of the lifting platform 1, telescopic rods 4 symmetrically fixedly connected to the top of the movable frame 3, a conveying device 5 fixedly connected to the top of the telescopic rods 4, a plurality of fixed columns 31 fixedly connected to the bottom of the lifting platform 1, a lifting assembly provided between the feed plate 2 and the conveying device 5, the lifting assembly being used to convey the molecular sieve raw material in segments to the top of the conveying device 5, and a feed assembly provided on one side of the feed plate 2, the feed assembly being used to convey the molecular sieve raw material to the upper surface of the feed plate 2.

[0033] During operation: The molecular sieve raw materials are mostly spherical or strip-shaped particles. The conveying device 5 mainly includes components such as a motor, drive shaft, and conveyor belt. The molecular sieve raw materials first enter the upper surface of the feed plate 2 through the feed assembly. Since the feed plate 2 is inclined, the raw materials will automatically slide down its slope into the interior of the lifting assembly after entering the upper surface of the feed plate 2. At this time, the lifting assembly moves upward, conveying the raw materials in segments to the conveying device 5. The raw materials will fall onto the surface of the conveyor belt. After the raw materials are lifted to the conveyor belt, they undergo other processing, thus completing the lifting and conveying process of the raw materials. After the lifting assembly has conveyed the raw materials, it will move downward. During the descent, the feed assembly will replenish the feed plate with subsequent raw materials. On the upper surface of 2, since the lifting component can easily change the height of the raw material lifting, the lateral position and longitudinal height of the conveying device 5 can be adjusted by the movable frame 3 and the telescopic rod 4. According to different working scenarios, the height of the raw material lifting is different, so the position of the conveying device 5 can be adjusted accordingly. Through the above embodiment, the raw material is lifted onto the conveyor belt in batches by the lifting component, which completely eliminates the problem of continuous material spillage caused by particle rolling, vibration or changes in accumulation height in traditional conveyor belts. It also facilitates batch processing of the raw materials conveyed to the conveyor belt. During the descent, the feeding component automatically replenishes the material, realizing a seamless cycle of lifting-unloading-replenishing, which greatly improves the efficiency of the entire raw material lifting process.

[0034] like Figures 2 to 7 As shown, the lifting assembly includes a conveyor plate 7 and a material carrier plate 8. The number of conveyor plates 7 and material carrier plates 8 is the same, and there are multiple conveyor plates 7 and material carrier plates 8. Each set of conveyor plates 7 and material carrier plates 8 is arranged in a stepped manner. The top surface of both conveyor plates 7 and material carrier plates 8 is inclined. Both conveyor plates 7 and material carrier plates 8 are perpendicular to the feed plate 2. One side of each material carrier plate 8 is attached to one side of the adjacent conveyor plate 7. The top surface of one conveyor plate 7 is attached to the inclined bottom surface of the feed plate 2. A driving assembly is provided on the side of the material carrier plate 8. The driving assembly drives multiple material carrier plates 8 to rise simultaneously along the inclined surface of the adjacent conveyor plates 7.

[0035] During operation: After the raw material slides along the inclined surface of the feed plate 2, a portion of the preceding raw material will enter the area above the first material carrier plate 8 via the feed plate 7 at the bottom of the inclined surface of the feed plate 2. At this time, the drive assembly is activated, causing the first material carrier plate 8 to rise. When the first material carrier plate 8, carrying the material, rises above the top surface of the second feed plate 7, the raw material can be poured into the top inclined surface of the second feed plate 7. Since all the material carrier plates 8 rise synchronously, the raw material poured into the top inclined surface of the feed plate 7 will stop on the side wall of the adjacent second material carrier plate 8. After the second material carrier plate 8 descends and resets, it will automatically slide down onto the top of the material carrier plate 8. During this process, since one side of each material carrier plate 8 is in contact with one side of the adjacent feed plate 7, when the raw material is poured from the material carrier plate 8 into the inclined surface of the feed plate 7... There will be no material blockage. Similarly, when the second material carrier plate 8 rises above the third feed plate 7 with the raw material above it, the raw material is poured into the top slope of the third feed plate 7 and enters the area above the third material carrier plate 8. The third material carrier plate 8 continues to rise and lift the raw material until the last material carrier plate 8 pours the raw material onto the conveyor belt, thus completing the entire raw material lifting process. In the first few lifts, each material carrier plate 8 will receive the raw material in segments. Once the material carrier plate 8 that is close to the conveyor belt receives the raw material, there will be raw material on top of each material carrier plate 8. Subsequently, in each subsequent movement of the lifting component, a batch of raw material will be conveyed to the top of the conveyor belt, from the initial segmented filling to the closed-loop cyclic conveying, thus realizing the continuous segmented conveying of raw materials.

[0036] It should be noted that the height of the raw material lifting can be further increased by increasing the number of feed plates 7 and material carrier plates 8, and the lateral position and longitudinal height of the conveying device 5 can be adjusted accordingly. Compared with the existing technology of lifting and conveying raw materials by inclined conveyor belt, the segmented lifting and conveying of raw materials adopted in this solution avoids the risk of material spillage caused by vibration, material accumulation or angle change of inclined conveyor belt. By increasing the number of material carrier plates, a vertical lifting of nearly 90 degrees can be achieved, which reduces the footprint compared with inclined conveyor belt.

[0037] like Figures 5 to 6 As shown, the top of the lifting platform 1 is symmetrically fixedly installed with side main plates 9, and the bottom of each feed plate 7 is fixedly installed on the top of the lifting platform 1. Each set of feed plates 7 and material carrier plates 8 are located between two side main plates 9. The top shaft of each material carrier plate 8 is hinged with a feed funnel 10, and the top surface of the feed funnel 10 is concave.

[0038] During operation: With the side main plate 9 in place, the raw material will not slip off the side of the feed plate 7 or the material carrier plate 8 during the lifting process, thus avoiding leakage. When the raw material slides onto the surface of the feed plate 7, it will rest against the side wall of the adjacent material carrier plate 8. When the material carrier plate 8 descends and resets, it will slide down the inclined surface of the feed plate 7 into the concave surface of the feed hopper 10. When the material carrier plate 8 lifts the feed hopper 10 and the raw material inside it, the feed hopper 10 will rotate 90 degrees when it rises above the next feed plate 7 or the conveyor belt. The raw material will be accurately and completely poured into the next feed plate 7 or the top of the conveyor belt. In the above embodiment, since the top surface of the feed hopper 10 is concave, it is convenient to receive the raw material and also convenient to pour it out.

[0039] like Figures 5 to 7 As shown, a gear 11 is fixedly connected to one end of the shaft of each material carrier plate 8, and multiple racks 12 are fixedly installed on one side of the side plate 9. The number of gears 11 and racks 12 are one-to-one and the teeth can mesh with each other.

[0040] During operation: When the material carrier plate 8 lifts the feed hopper 10 and the raw material inside it, the gear 11 will rise along a certain path. When the feed hopper 10 rises above the next feed plate 7 or the conveyor belt, the gear 11 will mesh with the rack 12, causing the gear 11 to rotate. The gear 11 will drive the feed hopper 10 to rotate. After the feed hopper 10 rotates, it will pour the raw material inside the concave surface into the next feed plate 7 or the top of the conveyor belt, so that the raw material can be accurately poured into the designated position.

[0041] like Figures 5 to 7 As shown, the number of teeth on rack 12 is one-quarter of the number of teeth on gear 11.

[0042] During operation: By setting the number of teeth of rack 12 to one-quarter of the number of teeth of gear 11, when gear 11 and rack 12 are meshed, they can drive the feed hopper 10 to rotate 90 degrees and pour out the raw material. When the material carrier plate 8 carries the feed hopper 10 down, gear 11 will continue to mesh with rack 12, causing the feed hopper 10 to rotate 90 degrees in the opposite direction to return to its original state.

[0043] like Figures 3 to 4As shown, the drive assembly includes multiple fixed seats 19, which are all fixedly installed on the outer wall of the side main board 9. Multiple sliding bar grooves 21 are opened on the inner wall of both side main boards 9. Connecting rods 20 are fixedly connected to both sides of each material carrier plate 8. The connecting rods 20 are slidably connected to the sliding bar grooves 21. The shaft of the gear 11 is slidably connected to the sliding bar grooves 21. An inner slider 17 is fixedly connected to one end of the connecting rod 20. A threaded conveying rod 18 is rotatably connected to the inner wall of each fixed seat 19. The inner slider 17 is threadedly connected to the outer wall of the threaded conveying rod 18 and slidably connected to the inner wall of the fixed seat 19.

[0044] During operation: When multiple threaded conveying rods 18 rotate simultaneously on the inner wall of the fixed seat 19, they will drive the inner slider 17 to slide along the inner wall of the fixed seat 19. This will cause multiple material carrier plates 8 to slide upwards simultaneously through the connecting rod 20. As a result, multiple material carrier plates 8 will drive multiple feed hoppers 10 and raw materials at different stages to be lifted, thus enabling the raw materials to be lifted synchronously in segments. Furthermore, by setting the sliding bar inclined groove 21, conditions are created for the sliding of the shaft of the connecting rod 20 and the gear 11, while also improving the stability during sliding.

[0045] like Figures 3 to 4 As shown, a rotating rod 16 is fixedly connected to one end of each threaded conveying rod 18, and a transmission ring 14 is fixedly connected to the end of each rotating rod 16 away from the threaded conveying rod 18. A transmission belt 15 is connected between the outer walls of the multiple transmission rings 14. A servo motor 13 is fixedly installed on the top of the lifting platform 1, and the output shaft of the servo motor 13 is fixedly connected to one of the transmission rings 14.

[0046] During operation: When the servo motor 13 is started, its output shaft will drive one of the transmission rings 14 to rotate. The transmission ring 14 will drive all the transmission rings 14 to rotate through the transmission belt 15. All the transmission rings 14 will drive the rotating rod 16 to rotate. The rotating rod 16 will cause multiple threaded conveying rods 18 to rotate simultaneously, thereby causing multiple material carrier plates 8 to move upward and be lifted at the same time.

[0047] like Figures 8 to 9 As shown, the feeding assembly includes a feeding bin 22, the bottom surface of which is inclined. A fixed base 23 is fixedly connected to the bottom of the feeding bin 22, and a rope 25 is fixedly connected to the bottom of the fixed base 23. One end of the rope 25 away from the fixed base 23 is fixedly connected to the bottom of one of the material carrier plates 8. A clamping seat 28 is fixedly connected to the bottom of the lifting platform 1. Fixed pulley 1 26 and fixed pulley 27 are rotatably connected to both ends of the clamping seat 28, respectively. The rope 25 is wound around the outer wall of fixed pulley 1 26 and fixed pulley 27, respectively.

[0048] During operation: When the material carrier plate 8 rises, it pulls the discharge bin 22 downwards via the rope 25 and the fixed base 23, causing the discharge bin 22 to descend to the upper surface of the lifting platform 1. Workers can then fill the discharge bin 22 with raw materials. When the material carrier plate 8 returns to its original position, the lifting assembly has already transported a portion of the raw materials to the conveying device 5. At this time, the discharge bin 22, carrying the filled raw materials, moves upwards. When the material carrier plate 8 returns to its original position, one end of the opening of the discharge bin 22 is aligned with the top surface of the baffle 6. The raw materials then enter the inclined surface of the baffle 6 along the inclined bottom surface of the discharge bin 22 and proceed along the inclined surface into the lifting assembly for lifting and conveying. In the above embodiment, the difficulty of feeding is avoided due to the baffle 6 being at a high position on the lifting platform 1. By feeding in real time, excessive raw materials are prevented from being loaded onto the baffle 6 at once, thus avoiding blockage and accumulation.

[0049] like Figures 8 to 9 As shown, a limiting plate 24 is provided on the bottom surface of the baffle 6. The bottom of the limiting plate 24 is fixedly connected to the top surface of the lifting platform 1. One side of the limiting plate 24 is attached to the opening of the discharge bin 22. A lifting column 30 is fixedly connected to the bottom of the fixed base 23. The lifting column 30 is fixedly installed on the top of the lifting platform 1. A return spring 29 is provided on the outside of the lifting column 30. One end of the return spring 29 is fixedly connected to the bottom of the fixed base 23, and the other end of the return spring 29 is fixedly connected to the outer wall of the lifting column 30.

[0050] During operation: When the material carrier plate 8 rises, it pulls the discharge bin 22 downward via the rope 25. During this process, the return spring 29 is compressed and deformed. When the material carrier plate 8 descends, the discharge bin 22 rebounds and rises under the action of the return spring 29 to align with the top surface of the baffle 6. When the discharge bin 22 moves to its highest point under the action of the return spring 29, it vibrates under the influence of the elastic force, which can better facilitate the raw material to slide onto the slope surface of the baffle 6. The opening of the discharge bin 22 is blocked by the limiting plate 24. Only when the discharge bin 22 rises to align with one side of the baffle 6 can the raw material slide from the bottom surface of the discharge bin 22 onto the slope surface of the baffle 6.

[0051] like Figure 9 As shown, baffles 6 are symmetrically fixedly connected to both sides of the feed plate 2, and an electric vibration block 32 is provided at the bottom of the feed plate 2.

[0052] During operation: The baffle 6 restricts the two sides of the feed plate 2, preventing the raw material from deviating from the direction and sliding out from the two sides of the feed plate 2 when it slides down the slope. The electric vibration block 32 keeps the slope of the feed plate 2 vibrating when conveying materials, preventing light raw materials from easily adhering to the slope and failing to slide down to the upper surface of the first feed plate 7.

[0053] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
