Abstract
Description
Technical Field
[0001] This utility model relates to the field of screening and dust removal technology, specifically a screening and dust removal device for molecular sieve production. Background Technology
[0002] Molecular sieves are synthetically produced hydrated aluminosilicates (zeolites) or natural zeolites that sieve molecules. Structurally, molecular sieves have numerous uniformly sized channels and neatly arranged pores. Different pore sizes allow molecular sieves to separate molecules of different sizes and shapes. They exhibit high adsorption capacity, strong selectivity, and high temperature resistance, making them widely used in organic and petrochemical industries. They are also excellent adsorbents for coal gas dehydration. Their application in waste gas purification is increasingly valued. The production process of molecular sieves includes raw material mixing, granulation, sieving, drying, calcination, and packaging. Producers use the sieving process to select semi-finished molecular sieve particles with particle sizes matching production requirements, ensuring the consistency of the finished product's particle size. During granulation and crushing, powdery debris is easily generated. Since this debris has low adsorption capacity, if not removed, it reduces the quality of the carbon molecular sieve. Dust is also generated during the sieving process, requiring treatment. Utility Model Content

Detailed Implementation
[0019] 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.
[0020] See Figures 1-3 In this embodiment of the present invention, a sieving and dust removal device for molecular sieve production includes a base 1, a support rod 2 fixedly connected to the base 1, a rotating shaft 3 rotatably connected to the support rod 2, one end of a rotating arm 4 fixedly connected to the rotating shaft 3, a connecting shaft 5 rotatably connected to the other end of the rotating arm 4, a vibrating screen 7 fixedly connected to the connecting shaft 5, a first motor 6 fixedly connected to the support rod 2, the output shaft of the first motor 6 fixedly connected to the driving end of the rotating shaft 3, a screen 8 fixedly connected inside the vibrating screen 7, a collecting hopper 9 fixedly connected to the bottom of the vibrating screen 7, a discharge pipe 10 fixedly connected inside the collecting hopper 9, a fixing frame 13 fixedly connected to the base 1, and a filter tank fixedly connected to the fixing frame 13. 14. A filter element is installed inside the filter tank 14. A fixed connecting cylinder 15 is fixedly connected to the bottom of the filter tank 14. A sliding connecting cylinder 16 is slidably connected inside the fixed connecting cylinder 15. A spring 17 is installed between the sliding connecting cylinder 16 and the fixed connecting cylinder 15. A collecting hopper 18 is fixedly connected to the sliding connecting cylinder 16. Multiple sets of spiral brushes 19 are fixedly connected to the inner wall of the collecting hopper 18. A collecting screen 20 is fixedly connected to the outer wall of the collecting hopper 18. A sliding connecting seat 21 is fixedly connected to the bottom of the collecting screen 20. The sliding connecting seat 21 is slidably connected to the vibrating screen 7. A feeding assembly is installed on the vibrating screen 7. An air suction assembly is installed on the top of the filter tank 14. A vibration assembly is installed inside the fixed frame 13.
[0021] In use, this utility model first connects the collecting screen 20 to the vibrating screen 7 through the sliding connection of the sliding connecting seat 21 and the vibrating screen 7. Then, the raw material is injected into the vibrating screen 7 through the feeding assembly. Then, the first motor 6 drives the rotating shaft 3 to rotate, the rotating shaft 3 drives the rotating arm 4 to rotate, and the rotating arm 4 drives the connecting shaft 5 to rotate, thereby driving the vibrating screen 7 to rotate and vibrate at high speed in the horizontal direction. Then, the raw material in the vibrating screen 7 is filtered through the screen 8. The filtered raw material passes through the screen 8 and enters the collecting hopper 18, and is then discharged along the discharge pipe 10. During the vibration process, the collecting screen 20 isolates the small particles of raw material that are raised, thereby avoiding dust.
[0022] The remaining raw material remains in the vibrating screen 7. Afterwards, simply remove the sliding connecting seat 21 from the vibrating screen 7, and the remaining raw material in the vibrating screen 7 can be directly removed from the outside.
[0023] Furthermore, during the screening process, the gas in the vibrating screen 7 is drawn into the filter tank 14 through the air intake component. When the gas flows into the filter tank 14, it first passes through the rotating brush and then the rotating brush filters out the small particles of raw material that are raised in the gas. The filtered small particles of raw material adhere to the rotating brush, and the remaining gas is then filtered through the filter element in the filter tank 14.
[0024] After the equipment has been running for a period of time, the collection bucket 18 can be driven to reciprocate through the vibration component. The high-frequency vibration of the collection bucket 18 will shake out the small particles attached to the spiral brush 19, and the shaken-out small particles will fall back into the vibrating screen 7.
[0025] In one instance of this embodiment, please refer to Figures 1-3 The material injection assembly includes a feed inlet 11 disposed in the side wall of the vibrating screen 7, and a feeding hopper 12 is fixedly connected inside the feed inlet 11. The material injection assembly injects raw materials through the feeding hopper 12 and enters the vibrating screen 7 through the feed inlet 11.
[0026] In one instance of this embodiment, please refer to Figures 1-3 The air intake assembly includes a duct 24 threaded to the top of the filter canister 14. A mounting base 25 is fixedly connected inside the duct 24. A second motor 26 is fixedly connected to the mounting base 25. A fan blade 27 is fixedly connected to the output shaft of the second motor 26. The air intake assembly drives the fan blade 27 to rotate through the second motor 26, thereby drawing the gas in the filter canister 14 into the duct 24 and discharging it along the duct 24.
[0027] In one instance of this embodiment, please refer to Figures 1-3The oscillation assembly includes a telescopic motor 23 fixedly connected to the fixed frame 13. A connecting rod 22 is fixedly connected to the output shaft of the telescopic motor 23. The connecting rod 22 is fixedly connected to the sliding connecting cylinder 16. The oscillation assembly drives the connecting rod 22 to perform high-frequency oscillation through the telescopic motor 23. The connecting rod 22 drives the collecting hopper 18 to perform high-frequency reciprocating oscillation through the sliding connecting cylinder 16. In turn, the high-frequency oscillation of the collecting hopper 18 shakes out the small particles of material attached to the spiral brush 19.
[0028] In one instance of this embodiment, please refer to Figures 1-3 A cone 28 is fixedly connected inside the fixed connecting cylinder 15. The present invention prevents the gas in the vibrating screen 7 from directly entering the fixed connecting cylinder 15 by setting the cone 28, thereby avoiding the material being directly sucked into the fixed connecting cylinder 15.

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.
