Description

Technical Field

[0001] The utility model relates to the technical field of crushing, in particular to a molecular sieve crushing device. Background Art

[0002] Molecular sieve is a kind of silicon-aluminate microporous crystal material with uniform pore size. It has extremely high specific surface area, good thermal stability, strong adsorption performance, large internal surface area and high strength. Molecular sieve can selectively adsorb according to the size and shape of molecules and is usually used in the fields of gas drying, gas separation, catalyst carrier, etc. In the production process of molecular sieve, high requirements are placed on the sphericity of the quality. Generally, the unqualified molecular sieves produced need to be crushed for reuse.

[0003] After investigation, a Chinese patent discloses a crushing device for nitrogen-making molecular sieve (publication number: CN220425542U), which includes a box body. A driving structure is arranged inside the box body, and a crushing structure is arranged inside the box body. The crushing structure includes two rotating rods. A limiting rod is fixedly connected to the outer side of the rotating rod, an extrusion wheel is welded to the outer side of the rotating rod, and a cutting tool is fixedly connected to the outer side of the extrusion wheel.

[0004] In the above patent, through the setting of the inclined block, when the molecular sieve is poured into the crushing device, it can preferentially fall into the junction of the two groups of cutting tools, thereby achieving the effect of rapid crushing and improving the operation efficiency. However, its drawback is that it lacks an automatic feeding mechanism. If the molecular sieve is directly poured into the crushing chamber, it is easy to cause the problem of excessive feeding and blockage of the device. Therefore, manual control of feeding is required, but this also increases the labor cost.

[0005] Therefore, the utility model provides a molecular sieve crushing device to solve the above problems. Summary of the Utility Model

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0025] The present invention provides a molecular sieve crushing device, as Figure 1 , Figure 2 and Figure 3 shown. The crushing device includes a support 1, a crushing box 2 fixedly installed on the support 1, a storage bin 3 fixedly installed on the crushing box 2, a feeding mechanism fixedly installed inside the storage bin 3 for feeding the molecular sieve, and a crushing mechanism fixedly installed inside the crushing box 2 for crushing the molecular sieve;

[0026] The feeding mechanism includes inclined plates 11 symmetrically installed inside the storage bin 3, a moving plate 12 slidably installed inside the storage bin 3, a connecting column 13 fixedly installed on one side of the moving plate 12, a threaded block 14 fixedly installed on the connecting column 13, and a bidirectional threaded rod 15 rotatably installed inside the threaded block 14.

[0027] The molecular sieve is placed inside the storage bin 3 before crushing. The inclined plates 11 inside the storage bin 3 can facilitate the feeding of the molecular sieve. The gap between the two inclined plates 11 is the feeding port of the molecular sieve. The size of this gap is changed by the movement of the moving plate 12, thereby realizing the control of the feeding amount. The movement of the moving plate 12 is achieved by rotating the bidirectional threaded rod 15. The threaded block 14 engaged with the bidirectional threaded rod 15 is connected to the moving plate 12 through the connecting column 13. Therefore, by rotating the moving plate 12 to force the threaded block 14 to drive the moving plate 12 to move, the size of the feeding port can be changed.

[0028] Furthermore, in order to improve the stability of the moving plate 12 during operation, as Figure 1 and Figure 3As shown, the top of the moving plate 12 is slidably attached to the bottom of the inclined plate 11. A strip-shaped chute is provided on the storage bin 3. The connecting column 13 is slidably connected inside the strip-shaped chute. The threaded block 14 is arranged outside the storage bin 3 and the side close to the connecting column 13 is slidably attached to one side of the storage bin 3.

[0029] The opening of the strip-shaped chute provides the prerequisite for the sliding of the connecting column 13 and driving the movement of the moving plate 12. The threaded block 14 is attached to the storage bin 3, providing a stable guarantee for the movement of the moving plate 12.

[0030] Furthermore, in order to enable the powder fragments 18 to crush the molecular sieve, as Figure 1 、 Figure 2 and Figure 4 shown, the crushing mechanism includes a rotating shaft 8 rotatably installed inside the crushing box 2, powder fragments 18 fixedly installed on the rotating shaft 8, and a scraping blade 9 fixedly installed inside the crushing box 2. One side of the scraping blade 9 is movably attached to one side of the powder fragments 18.

[0031] The powder fragments 18 are arranged on the rotating shaft 8. By driving the rotation of the rotating shaft 8, the powder fragments 18 can crush the molecular sieve. The scraping blade 9 being attached to the powder fragments 18 enables the rotating shaft 8 to automatically scrape off the residual molecular sieve on the powder fragments 18 when driving the powder fragments 18 to rotate.

[0032] Among them, in order to enable the rotating shaft 8 to rotate, as Figure 1 、 Figure 2 and Figure 4 shown, both ends of the rotating shaft 8 penetrate through the crushing box 2. An installation plate 6 is fixedly connected to the crushing box 2. A motor 7 is fixedly connected to the installation plate 6. The output end of the motor 7 is fixedly connected to one end of the rotating shaft 8. A gear 10 is fixedly connected to the other end of the rotating shaft 8.

[0033] Since there are two sets of the rotating shaft 8 and its corresponding parts, there are also two gears 10 and they are meshed with each other. There is one motor 7 and it is connected to one of the rotating shafts 8. After driving one of the rotating shafts 8 to rotate by the motor 7, due to the influence of the meshing of the gears 10, the other rotating shaft 8 will also rotate, thereby driving the powder fragments 18 to crush the molecular sieve.

[0034] It should be noted that in order to enable the bidirectional threaded rod 15 to rotate stably, as Figure 1 、 Figure 2 and Figure 3 shown, a fixing block 17 is sleeved on the bidirectional threaded rod 15. One side of the fixing block 17 is fixedly connected to one side of the storage bin 3. One end of the bidirectional threaded rod 15 is fixedly connected to a handle 16.

[0035] The staff can rotate the handle 16, causing the handle 16 to drive the bidirectional threaded rod 15 to rotate. The fixed block 17 is provided to ensure the stable rotation of the bidirectional threaded rod 15.

[0036] Furthermore, to facilitate the collection of the pulverized molecular sieve, as Figure 1 , Figure 2 and Figure 4 shown, a discharge hopper 4 is fixedly connected to the bottom of the pulverizing box 2, and a collection box 5 is arranged directly below the discharge hopper 4. The collection box 5 is movably connected to the bracket 1.

[0037] The collection box 5 is located inside the bracket 1 and relies on the support rods on the bracket 1 as supports to receive the molecular sieve falling from the discharge hopper 4, facilitating collection by the staff.

[0038] When the molecular sieve is pulverized, uniform feeding can reduce blockage and uneven filling problems during the production process, thereby improving the operating efficiency and output of the production line.

[0039] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
