Description

Technical Field

[0001] This utility model relates to the technical field of pulverizing equipment, specifically a pulverizing device for molecular sieve production. Background Technology

[0002] Molecular sieves are aluminosilicate compounds with a cubic lattice. They possess a uniform microporous structure with consistent pore diameter. These pores adsorb molecules smaller than their diameter into the interior of the pores, exhibiting preferential adsorption of polar and unsaturated molecules. Therefore, they can separate molecules with different degrees of polarity, saturation, size, and boiling point, effectively "sieving" molecules, hence the name molecular sieve. Due to their high adsorption capacity, strong selectivity, and high-temperature resistance—advantages not found in other adsorbents—molecular sieves are excellent adsorbents for coal gas dehydration, leading to their widespread application. However, during the manufacturing process, a high degree of sphericity is crucial for the quality of molecular sieves.

[0003] Currently, the manufacturing process of molecular sieves often requires the use of a crushing device to crush the raw materials. The raw materials for making molecular sieves are put into the crushing device according to the proportion, and the crushing device operates to crush and mix the various raw materials. However, the existing crushing devices all use a single shaft to drive the cutter and crushing rod to rotate. This crushing method is relatively simple and easily leads to uneven size of the mixed raw material powder, thus affecting the quality of the finished molecular sieve. Utility Model Content

Detailed Implementation

[0017] 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.

[0018] See Figures 1-3 In this embodiment of the present invention, a pulverizing device for molecular sieve production includes a base 1, a support rod 2 fixedly connected to the base 1, a crushing cylinder 3 fixedly connected to the support rod 2, a feeding hopper 4 fixedly connected to the top of the crushing cylinder 3, an extrusion cylinder 5 fixedly connected inside the crushing cylinder 3, a crushing head 6 disposed inside the extrusion cylinder 5, a mounting base fixedly connected to the bottom of the crushing cylinder 3, an mounting block 8 fixedly mounted on the mounting base by mounting bolts 7, a fixed grinding disc 9 fixedly connected to the mounting block 8, a sliding bearing 20 fixedly connected inside the fixed grinding disc 9, a rotating connecting seat 12 fixedly connected outside the sliding bearing 20, and a rotating grinding disc 13 rotatably connected to the rotating connecting seat 12. The rotating grinding disc 13 and the fixed grinding disc 9 cooperate with each other. The fixed grinding disc 9 is provided with a material trough 10 at the top and a material discharge port 11 at the bottom. The material discharge port 11 connects the material discharge port and the top of the rotating grinding disc 13. A hydraulic telescopic pump 19 is fixedly connected to the base 1. The output shaft of the hydraulic telescopic pump 19 passes through the sliding bearing 20 and is fixedly connected to the crushing head 6. The output shaft of the hydraulic telescopic pump 19 is slidably connected to the sliding bearing 20. A material discharge hopper 22 is provided at the bottom of the rotating grinding disc 13. The material discharge hopper 22 is inclined. The lowest end of the material discharge hopper 22 is provided with a discharge port 23. The material discharge hopper 22 is fixedly connected to the support rod 2 by a fixing rod 21.

[0019] A drive assembly is provided between the base 1 and the rotating grinding disc 13 for driving the rotating grinding disc 13 to rotate.

[0020] This invention first receives large pieces of raw material through the hopper 4, and then drives the crushing head 6 to reciprocate up and down in the extrusion cylinder 5 through the hydraulic telescopic pump 19. When the crushing head 6 rises, small pieces of raw material fall through the gap between the crushing head 6 and the extrusion cylinder 5 into the material holding trough 10 at the top of the fixed grinding disc 9, while large pieces of raw material are stuck between the crushing head 6 and the extrusion cylinder 5. Then, the hydraulic telescopic pump 19 drives the crushing head 6 to press down, thereby compressing and crushing the large pieces of raw material stuck between the crushing head 6 and the extrusion cylinder 5 through the compression between the crushing head 6 and the extrusion cylinder 5. Then, when the crushing head 6 rises again, the crushed raw material falls back into the material holding trough 10 under the action of gravity.

[0021] Simultaneously, the rotating grinding disc 13 is driven to rotate by the drive component. The rotating grinding disc 13 rotates relative to the fixed grinding disc 9. At this time, the raw material in the trough 10 falls from the discharge port 11 to the space between the fixed grinding disc 9 and the rotating grinding disc 13. Then, through the relative rotation between the fixed grinding disc 9 and the rotating grinding disc 13, the raw material is ground and crushed. The ground raw material is then received by the discharge hopper 22. Under the action of gravity, the raw material in the discharge hopper 22 slides from the top of the discharge hopper 22 to the bottom of the discharge hopper 22 and is finally discharged through the discharge port 23.

[0022] In one instance of this embodiment, please refer to Figures 1-3 An extrusion groove is provided between the crushing head 6 and the extrusion cylinder 5. This utility model uses the extrusion groove to crush large raw materials.

[0023] In one instance of this embodiment, please refer to Figures 1-3 The drive assembly includes a connecting shaft 14 fixedly connected to the bottom of the rotating grinding disc 13, a first gear 15 fixedly connected to the connecting shaft 14, a fixed frame 16 fixedly connected to the base 1, a motor 17 fixedly connected to the fixed frame 16, a second gear 18 fixedly connected to the output shaft of the motor 17, and the second gear 18 meshing with the first gear 15.

[0024] The drive assembly drives the second gear 18 to rotate via the motor 17. The second gear 18 drives the first gear 15 to rotate via meshing with the first gear 15. The first gear 15 drives the rotating grinding disc 13 to rotate via the connecting shaft 14.

[0025] The working principle of this utility model is as follows: First, the large pieces of raw material are received by the hopper 4. Then, the hydraulic telescopic pump 19 drives the crushing head 6 to reciprocate up and down in the extrusion cylinder 5. When the crushing head 6 is raised, the small pieces of raw material fall from the gap between the crushing head 6 and the extrusion cylinder 5 into the material holding trough 10 at the top of the fixed grinding disc 9. The large pieces of raw material are stuck between the crushing head 6 and the extrusion cylinder 5. Then, the hydraulic telescopic pump 19 drives the crushing head 6 to press down, thereby crushing the large pieces of raw material stuck between the crushing head 6 and the extrusion cylinder 5 through compression. Then, when the crushing head 6 is raised again, the crushed raw material falls back into the material holding trough 10 under the action of gravity.

[0026] Simultaneously, the motor 17 drives the second gear 18 to rotate. The second gear 18 meshes with the first gear 15, which in turn drives the first gear 15 to rotate. The first gear 15 drives the rotating grinding disc 13 to rotate via the connecting shaft 14. The rotating grinding disc 13 rotates relative to the fixed grinding disc 9. At this time, the raw material in the trough 10 falls from the discharge port 11 to the space between the fixed grinding disc 9 and the rotating grinding disc 13. The relative rotation between the fixed grinding disc 9 and the rotating grinding disc 13 grinds and crushes the raw material. The ground raw material is then received by the discharge hopper 22. Under the action of gravity, the raw material in the discharge hopper 22 slides from the top to the bottom of the discharge hopper 22 and is finally discharged through the discharge port 23.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
